Hooper [57] ABSTRACT A cable shield connector for providing electrical shield continuity at splice points or terminals utilizes contoured plates between which the shield and plastic outer jacket of the cable section are clamped. The inner plate has an upstanding tang or tab on one end thereof and an upwardly protruding threaded stud spaced from the tab. The other end of the inner plate is slipped beneath the shield and an outer plate is mounted on the I. sud stud over the exterior of the plastic jacket. As the plates are forced toward each other, the outer plate first contacts the tab and tends to pivot thereabout tightly clamping the shield and jacket between the ends of the plates. The inner plate can have an insulating layer on the underside thereof to prevent shorting of the cable conductors to the cable shield if damage occurs to the conductor insulation.

frnore particularly to cable connectors for providing jeans shield continuity at cable splice points and termifials- I '2. Descriptionofthe Prior Art Cable systems normally contain a plurality of discrete cable sections which are' joined together at splice points and which are joined to other apparatus at terminal points. Each of these discrete cable sections comprises a core of conductors within protective sheaths normally including an electrical shield and an outer protective plastic jacket. At splice points and terminals it is necessary to insure continuity of the electrical shield for proper electrical protection of the conductors.
one type of connector for providing electrical shield continuity clamps directly onto the thin shield alone. However, such connectors tear or damage the thin conductive shield and thereby lose their effectiveness.
Another typeof connector for providing shield conti- 'nuity comprises'a base which fits beneath the shield and has a stud protruding outwardly through a slit in the shield and outerjacket. An outer bridge is mounted on the stud to clamp the shield and, jacket between the base and the bridge.,A major disadvantage of such connectors is the necessity for slitting or tabing the cable shield and outer jacket to allow the stud to protrude.
' The slitting step adds considerably to the cost of installing such connectors. Further, the slitting step often results in cuts or damage to the insulation on the cable conductors thereby causing these conductors to be shorted to the cable shield. Additionally the slit cannot be completely closed after the connector is installed because of the stud protruding therethrough. Thus the shield is not in contact with the inner plate over a substantial portion of its surface and thereby an increase in contact resistance is produced.
Accordingly, it is an object of this invention to eliminate the necessity for slitting the cable shield and jacket for installing cable shield connectors.
Another object is to improve cable'shield connectors to prevent damage to the cable shield.
A further object is to improve cable shield connectors to provide better electrical contact with the shield simultaneous with a mechanically stronger connection.
A still further object is to increase the contact area between, the connector and cable shield to thereby decrease the contact resistance.
SUMMARY OF THE INVENTION The foregoing objects and others are achieved in ac- A cordance with the principles of this invention by the use of a connector comprising contoured plates between the ends of which'the'electrical shield and plastic spaced from the tab. The opposite end of the inner plate is slipped beneath the shield until the stud 'contacts the ends of the shield and jacket. The outer plate is inserted on the stud over the jacket and forced toward the inner plate by a nut. The outer plate first contacts the upstanding tab of the inner plate and tends 'to pivot thereabout causing the other ends of the plates to tightly clamp the shield and jacket therebetween. The tightening action also imparts a force component to the inner plate which keeps it securely wedged under the shield. The inner plate contacts the shield over the entire portion thereof which is inserted in the cable to thereby provide a low resistance connection. The lower surface of the inner plate is coated withan insulation to prevent any shorting of conductors to the cable shield in the event of damage to the conductor insulation.
BRIEF DESCRIPTION OF THEDRAWINVJXGSYP The invention will be more fully comprehended from the following detailed description and accompanying drawing in which:
FIG. 1 is an exploded perspective view of a cable shield connector; and
FIG. 2 is an exploded perspective view showing th connector of FIG. 1 installed on a cable. H
DETAILED DESCRIPTION 1 FIG. 1 shows in detail acable shield connector 101 in accordance with the principles of this invention.Connector 101 comprises aninner plate 10, anouter plate 20 and mountinghardware 30 such as nuts and washers formounting plates
Inner plate has a threadedstud ll integrally fastened thereto by some method such as welding and projecting upwardly from the upper surface 12 thereof. Upper surface 12 also has a plurality ofserrations 13 or other projections to insure good electrical contact with the cable shield when the connector is installed. On one end'17 ofplate 10 is an upstanding tab ortang 14 which is integrally formed as part ofplate 10. Tang l4 advantageously can have a slight angle backward from a plane perpendicular to surface 12 so that a force applied to the top edge oftang 14 will have a component parallel to surface 12 for reasons to become apparent subsequently. The height of tang l4 advantageouslycan be greater than the combined thicknesses of the jacket and shield of the cable on whichconnector 101 is installed. On the bottom ofplate 10 is aninsulating layer 15 which preventsplate 10 from shorting the cable shield to the conductors in the event of damage to the insulation of the conductors whenconnector 101 is installed.
Outer plate has an opening 21 through which stud 11 onplate 10 is inserted. The inner surface ofplate 20 has a plurality of sharp projections ortangs 22 for insuring a good mechanical bond to the plastic jacket of the cable over whichplate 20 is installed.Plate 20 has a length sufficient to insure thattang 14 onplate 10 firmly contacts theinner surface 23 ofplate 20 on oneend 25 thereof whenplate 20 is installed on stud 11.
Theinner surface 23 ofplate 20 can have a notch or groove, not shown, in which tang 14 fits to prevent any slippage ofplate 20 with respect totang 14 after installation.Plate 20 also has twoupstanding tabs 24 on theother end 26 thereof for retaining a cable clamp onconnector 101 should it become desirable to install such a clamp around the cable.
In FIG. 2, where like numbers refer to like elements, an exploded view ofconnector 101 of FIG. 1 installed on a cable 40 is shown. Inner plate is slid betweenconductors 41 and shield 42 until stud 11 butts against theends plastic jacket 43 and shield 42 respectively. Aplastic sheath 46 is shown surroundingconductors 41 but can readily be omitted. No slit or incission need be made injacket 43 or shield 42 as is required in prior art cable connectors. Outer plate is installed overjacket 43 and a portion of mounting hardward 30 is then installed on stud 11. Ashardware 30 is tightened, theinner surface 23 on end ofplate 20 first contacts tang 14. As hardware is further tightenedplate 20 pivots abouttang 14 thereby forcingend 26 ofplate 20 and end 16 ofplate 10 tightly together and clamping shield 42 andjacket 43 therebetween. The large clamping forces preventplate 10 from slipping from beneath shield 42. Furthermore, the force applied totang 14 byouter plate 20 can include a component parallel to the cable axis which tends to keepplate 10 shoved beneath shield 42. The relative magnitude of this component depends on the angle of incline oftang 14 with respect to a plane perpendicular to surface 12. Anappropriate conductor 50 is then mounted on stud 11 with another portion ofhardware 30 and electrically connects shield 42 across a splice point or to a terminal.
Previously, cable shield connectors could not be used without slitting the cable jacket and shield. Such connectors had no tang such astang 14 which made initial contact with the outer plate and about which the outer plate pivoted. Tabs or tangs similar in appearance totang 14 have been previously used on the inner plates of cable connectors but such tabs were used for facilitating insertion of the inner plate only. Such tabs extended beyond the end of the outer plate and made no contact therewith. Therefore, if one of these previous connectors were utilized with the stud only abutting the ends of the jacket and shield as shown with respect to the instant connector instead of protruding through a slit in the shield, the outer plate thereof would pivot about the end of the jacket in a direction opposite to the pivoting of the outer plate of the connector of this invention. Thus there would be no clamping of the jacket and shield between the inner and outer plate as required.
The elimination of the necessity for slitting the cable shield and jacket greatly reduces the time required for installingconnector 101. Additionally, the danger of damage to the insulation ofconductors 41 orsheath 46 from the sharp cutting tools required for slitting is eliminated. The elimination of the slit also increases the contact area between shield 42 andinner plate 10 thereby resulting in better connection with lower contact resistance. In previous contours the slit could not be completely closed after the insertion of the inner plate because of the stud protruding therethrough. Thus the portion of the inner plate directly beneath the slit made no contact with the shield.
Various modifications such as varying the numbers and configurations of the projecting tangs can be made without departing from the spirit and scope of the invention.
