Abstract

A shaped anchor member for anchoring a telephone handset to a telephone housing wherein a stranded cable is employed to mechanically connect the handset and the housing. An end portion of the stranded cable is disposed within the anchor member. The anchor member is provided with a top compound surface having first and second radii of curvature such that the compound surface is in substantially full surface contact with an interior surface of the handset at the junction of the handset yoke and receiver.

Description

This is a continuation-in-part of co-pending application Ser. No. 915,353 filed on Oct. 6, 1986 now abandoned.

BACKGROUND OF THE INVENTION

In the anchoring system employed in U.S. Pat. No. 4,518,830, the handset end of the tca is crimped so as to fit between the transmitter cup legs. The legs and an interior surface of the transmitter end of the handset retain the tca in position. If the spacing between the transmitter cup legs exceeds the outer diameter of the tca, they will not anchor the tca against longitudinal displacement. Thus, when the handset is pulled away from the telephone housing, the handset end of the tca is forced against the grommet. If the handset is pulled with sufficient force, the tca may be forced through and pulled out of the grommet. Likewise, the handset end of the tca may be pushed through the transmitter end of the handset into an acoustic foam block at the junction of the handset transmitter and yoke portions. One problem solved by the present invention is that of anchoring the stranded cable at the yoke-receiver junction of the handset without danger of rupture of the junction wall when forces up to the 800 pound tensile strength of the stranded cable are applied. Another problem solved by the present invention is that of anchoring the handset end of the tca against longitudinal and rotational displacement in the transmitter end of the handset.

The invention includes the discovery that rupture of the handset wall at the yoke-receiver junction is due to "point" contact between the relatively sharp edges of the conventional wedge-shaped anchor member and the compound interior surface of the handset at the yoke-receiver junction. The invention also includes recognition of the inability of the transmitter cup legs to reliably anchor the handset end of the tca in position against longitudinal and rotational displacement at the transmitter end of the handset.

In my invention, the anchor member is shaped so as to have a top compound surface matching the shape of the compound interior surface of the handset at the yoke-receiver junction such that full surface contact is maintained between the anchor member and the handset interior compound surface at the yoke-receiver junction. Such contact distributes the forces produced when the handset is pulled away from the telephone housing so that the forces cannot concentrate at a "point" or even along a "line" thereby preventing rupture of the handset wall at the junction. In addition, in my invention, the handset end of the tca is positively anchored against longitudinal and rotational displacement by a retainer member mounted on the tca and sandwiched between the grommet and transmitter cup legs.

Other advantages of the invention are described hereafter.

DETAILED DESCRIPTION OF INVENTION

Referring to the drawings, wherein like numerals indicate like elements, there is shown in FIG. 1 atelephone housing 10 of the public or "pay" type and ahandset 12. Thehousing 10 andhandset 12 are conventional structures. Thetelephone signal wires 14 and a strandedcable 16 are sheathed intca 18 between thehousing 10 andhandset 12. Thetca 18 extends through agrommet 20 secured to thetransmitter end 22 of the handset. Thetca 18 protects thesignal wires 14 andcable 16 from vandalism.

The system for anchoring thecable 16 andtca 18 inhandset 12 according to the present invention is best shown in FIG. 2. Thehandset 12 includes a receiver end orportion 24 and ayoke 26 connecting the transmitter and receiver ends 22, 24. Thehandset 12 is a conventional one-piece structure provided with

screw caps

28, 30 at the transmitter and receiver ends respectively. The tca extends throughgrommet 20 below thetransmitter cup 32 through thetransmitter cup legs 34. Aferrule 36 is secured in conventional manner to the end of the tca. The ferrule is provided with an opening allowing for passage of thecable 16 andsignal wires 14.

Thecable 16 is anchored in thehandset 12 by means of acable anchor member 38 which is inserted in the handset at the yoke-receiver junction. The junction is generally indicated by 40 in FIG. 2. Thetop surface 42 of theanchor member 38 includes a generally concavo-convex surface which "matches" the convex-concaveinterior surface 44 of the handset at the yoke-receiver junction 40 as shown in FIGS. 3-8.

Thecable anchor member 38 and yoke-receiver junction 40 are best shown in FIGS. 3-8. Thebottom surface 46 of the cable anchor member is substantially flat, and it contacts a substantially flatinterior surface 48 of the handset at the yoke-receiver junction 40. Thus, thetop compound surface 42 and flatbottom surface 46 of the cable anchor member contact the handset interior surfaces 44, 48 at the yoke-receiver junction so as to maintain full surface contact between the cable anchor member and the interior surfaces 44, 48 of the handset. The side surfaces 50, 52 of the cable anchor member are substantially flat. Preferably, the side surfaces converge towards thetransmitter end 22 of the handset with slight taper such as 3° so as to provide pilot surfaces facilitating placement of thecable anchor member 38 in the yoke-receiver junction 40.

Preferred dimensions of thecable anchor member 38 are as follows. Thetop compound surface 42 includes a lower, relativelyflat surface portion 54 which leads into a concavo-convex surface portion 56 having a 1/2 inch radius of curvature along the direction of the longitudinal axis L of the handset and a 11/8 inch radius of curvature along a direction transverse and substantially perpendicular to the longitudinal axis of the handset. The cable anchor member is provided with a substantially flatfront surface 58 and a substantially flatrear surface 60. The distance between the front and

rear surfaces

58, 60 is 11/4 inch. The width of the front surface is 1.060 inch. The width of therear surface 60 is 1.125 inch. The concavo-convex portion 56 leads into an upper, substantiallyflat surface portion 62 along an arcuaterounded edge 64.Edge 64 is defined by an arc running transverse to the longitudinal axis of the anchor member with a radius of curvature of 11/8 inch. The edge is rounded with a radius of curvature of 3/32 inch. The

surfaces

54, 56 and 62 intersect the side surfaces 50, 52 along rounded

edges

66, 68 each having a radius of curvature of 3/32 inch. Thefront surface 58 intersects the side surfaces 50, 52 along straight, rounded edges 70, 72 each having a radius of curvature of 3/32 inch. Thefront surface 58 intersects thelower surface portion 54 along a straight, roundededge 74 having a radius of curvature of 1/16 inch. The side surfaces 50, 52 intersectbottom surface 46 along straight, rounded edges 76, 78 each having a radius of curvature of 3/32 inch. Thebottom surface 46 intersects thefront surface 58 along a straight, roundededge 80 having a radius of curvature of 1/16 inch. Aslot 82 is formed in thebottom surface 46 parallel to the longitudinal axis of the anchor member to accommodate thecable 16. A circular bore orpassage 84 is formed in therear surface 60. Thepassage 84 intersects theslot 82 so as to define ashoulder 86 which serves as a stop surface for an end stop or plug 88 secured to the end ofcable 16.

Cavities

90, 92 may be formed betweenpassage 84 and the side surfaces 50, 52 so as to make the anchor member lightweight.

Thecable anchor member 38 is formed of a hard, polymeric plastic material such as ABS. By rounding the intersecting edges of the cable anchor member surfaces, and by forming the top compound surfaces of the anchor member as described, "point" or "line" contact between the anchor member and the interior surfaces of the handset at the yoke-receiver junction are avoided. Accordingly, when the handset is pulled away from thetelephone housing 10, end stop 88 seats inpassage 84 againstshoulder 86, and all forces are distributed over an area of full surface contact between the cable anchor member and the interior surface of the handset. As a result, rupture of the handset wall at the yoke-receiver junction will not occur even at forces which are commensurate with the 800 pound tensile strength ofcable 16.

Thetca 18 is anchored in thetransmitter end 22 ofhandset 12 by aretainer member 94. Thetca retainer member 94 is best shown in FIGS. 10 and 11. Theretainer member 94 is a block of hard, polymeric plastic material having a through-bore orpassage 96 extending from afront face 98 to a rear face 100 (FIG. 2). The retainer member is also provided with aslot 102 extending from atop face 104 to abottom face 106 and intersecting thepassage 96. The diameter of thepassage 96 is slightly greater than the outer diameter offerrule 36 so that thetca 18 andferrule 36 can freely slide through the passage. Anend portion 108 of thetca 18proximate ferrule 36 is swaged. A metallic, generallyU-shaped clip 110 is inserted inslot 102 such that the

clip legs

112, 114 at least partially protrude within thepassage 96. The spacing between the

clip legs

112, 114 is less than the outer diameter of the tca so that the legs fit over the swagedend portion 108 of the tca thereby preventing any appreciable longitudinal or rotational displacement of the tca withinpassage 96. Thus, thetca 18 is locked in theretainer member 94.

Theretainer member 94 itself is anchored in position against longitudinal and rotational displacement by thegrommet 20, thebottom surface 116 of thetransmitter cup 32, thetransmitter cup legs 34 and the bottom interior surface 118 of thetransmitter end 22 of the handset. Thus, whenscrew cap 28 is secured to thehandset 12,transmitter cup 32 and the bottom interior surface 118 of thetransmitter end 22 of the handset prevent rotational displacement of theretainer member 94 hence rotational displacement of thetca 18 about its longitudinal axis. Also, if the tca is pushed into thetransmitter end 22 of the handset, thetransmitter cup legs 34 provide a stop surface which is contacted by therear face 100 of theretainer member 94 thereby preventing longitudinal displacement of the retainer member hence longitudinal displacement of the tca. And if thetca 18 is pulled away from thetransmitter end 22 of the handset, thegrommet 20 provides a stop surface which is contacted by thefront face 98 of theretainer member 94 thereby preventing longitudinal displacement of the retainer member hence longitudinal displacement of the tca. Accordingly, thetca 18 can neither be pushed through thetransmitter end 22 to theyoke 26 of the handset nor pulled from thetransmitter end 22 through thegrommet 20.

Thetca 18 is anchored in thetelephone housing 10 by means of a combined cable-tca retainer member 120. The cable-tca retainer member 120 is best shown in FIGS. 12 and 13. Retainer member 120 is a five sided, hollow rigid metallic block having

side walls

122, 124, slotted top and

bottom walls

126, 128 and arear wall 130. Aferrule 132 is secured to the telephone housing end of thetca 18 and is provided with a passage through which thesignal wires 14 and thecable 16 extend. The telephone housing end of thetca 18 is inserted through acircular opening 134 in awall 136 of thetelephone housing 10. The telephone housing end portion of thetca 18 is swaged as at 138.Swaged portion 138 of the tca is located in aslot 140 formed in akeeper plate 142 which is screw fastened to aconventional mounting block 137 secured to wall 136 inside the telephone housing. Thekeeper plate 142 has anear 143 which is captured in a portion of the mounting block and aflange 145 provided with ascrew hole 147. The swagedportion 138 of the tca also extends through aslot 144 in thebottom wall 128 of the retainer member 120. Thekeeper plate 142 andbottom wall 128 of the retainer member provide stop surfaces which contact shoulders 146, 148 and 150, 152 at the swagedportion 138 of the tca thereby preventing longitudinal displacement of the tca. Thus, the tca cannot be pushed into or pulled from thetelephone housing 10. In addition, thekeeper slot 140 and thebottom wall slot 144 of the retainer member have identical widths which permit insertion of the swagedportion 138 of the tca with only slight clearance such that thekeeper plate 142 andbottom wall 128 prevent rotational displacement of the tca about its longitudinal axis. The end portion of thetca including ferrule 132 is prevented from sliding out of thebottom wall slot 144 by acotter pin 154 which extends through aligned

The telephone housing end of thecable 16 extends through aslot 160 in thetop wall 126 of the retainer member 120. Thetop wall 126 provides a stop surface for an end stop or plug 162 secured to thecable 16. Thecable 16 is retained inslot 160 by acotter pin 164 which extends through aligned

openings

166, 168 in

side walls

122, 124. Thus, the retainer member 120 serves to anchor both thetca 18 andcable 16 within thetelephone housing 10.

Referring to FIG. 15, there is shown an alternative embodiment of the tca retainer member designated 94'. The tca retainer member 94' is best shown in FIGS. 16 and 17. The retainer member 94' is a rigid, generally L-shaped metal clip having aslot 200 extending from anupper leg 202 to alower leg 204. The portion ofslot 200 inleg 202 is generally elongated and has a width slightly greater than the width of the swagedend portion 108 of thetca 18. The portion ofslot 200 inleg 204 is in the shape of a partial circle having a diameter which is greater than the width of the portion ofslot 200 inleg 202. The diameter of the portion of the slot inleg 204 is slightly greater than the outer diameter of theferrule 36 so that the ferrule end of thetca 18 may be inserted through the portion of theleg 204 as shown in solid lines in FIG. 17. Thetca 18 can then be displaced upwardly through the portion ofslot 200 inleg 202, as shown in FIG. 17, along the swagedend portion 108 thereof. The edges of theslot 200 inleg 202 will then prevent longitudinal and rotational displacement of the tca.

As shown in FIG. 15, the tca retainer member 94' is captured by inserting theclip leg 202 in the gap between the

transmitter cup legs

34 and 206. Preferably, the thickness ofleg 202 is chosen to ensure that the leg is captured by frictional engagement with the

transmitter legs

34, 206. As shown in FIG. 21, thetransmitter cup 32 and retainer clip 94' may be rotated 180° so as to captureleg 202 between

transmitter legs

34, 206 and against thegrommet 20.

Although the system of the present invention has been described in terms of acable anchor member 38, tca retainer member 94 (or 94') and combined cable-tca retainer member 120, and it is preferred that all such elements be used in combination, the elements may also be used independently of each other. Thus, thecable anchor member 38 anchors thecable 16 at the yoke-receiver junction of thehandset 12 while the tca retainer member 94 (or 94') anchors the tca at thetransmitter end 22 of thehandset 12. Although thecable 16 is sheathed in thetca 18 between thetelephone housing 10 and thehandset 12, the cable and tca are not mechanically connected, and they are separately anchored in the handset. Similarly, although the combined cable-tca retainer member 120 serves to anchor both thetca 18 andcable 16 at thetelephone housing 10, the tca and cable are separately anchored by the top and

bottom walls

126, 128 of retainer member 120.

Although the invention has been described in connection with ahandset 12 having

screw caps

28, 30, it should be understood that in public or "pay" telephone systems of this type the caps are welded or otherwise secured to the handset so that the caps cannot be removed from the handset.

Also, although thecable anchor member 38 has been described as being inserted in the yoke-receiver junction 40 of thehandset 12, so that the anchor member interacts with the interior surfaces of the handset at the yoke-receiver junction so as to provide a stop surface for thecable end stop 88 when the handset is pulled away from thetelephone housing 10, the anchoring action may be further improved by welding thecable anchor member 38 to the interior surfaces of the handset at the yoke-receiver junction. Thus, thecable anchor member 38 may be ultrasonically welded to the interior surfaces of the handset at the yoke-receiver junction so as to provide a unified body of increased strength. It should be understood, however, that whether thecable anchor member 38 is welded to the interior surfaces of the handset or not, theanchor member 38 prevents rupture of the handset wall at the yoke-receiver junction despite the application of forces up to the 800 pound tensile strength of thecable 16 itself.

Further, although thecable anchor member 38 has been described in connection with a concavo-convex surface having particular radii of curvature, it should be understood that the shape of the surfaces of the cable anchor member are generally chosen to match the shape of the interior surface of the handset at the yoke-receiver junction to ensure optimal surface contact between the anchor member and handset.

Although an alternative embodiment of the tca retainer member 94' has been described as a generally L-shaped

clip having legs

202, 204, it should be apparent thatleg 204 can be dispensed with whereby theleg 202 would be generally U-shaped around theslot 200, similar in shape to clip 110 in FIG. 10. Such a retainer clip, designated 94", is shown in FIGS. 19 and 20. Thetransmitter cup 32 andretainer clip 94" may be rotated 180° so as to place theclip 94" against thegrommet 20 in the manner previously explained in connection with retainer clip 94' and FIG. 21.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
