Description

BACKGROUND OF THE INVENTIONField of the Invention

The invention is a circular rapid-joint connector, particularly relating to one which may be in direct docking with a connection socket by a connector plug when using, such that effects of rapid joint, solid joining, rapid disassembling, simple structure and facile of use are accomplished.

Descriptions of the Related Art

Conventionally, the "Circular Connector", U.S. patent US 6,517,373 B2, includes a first connector element and a second connector element each of which has a first contact inset or a respective second contact inset in which, around the first contact inset of the first connector element, a sleeve-shaped latch segment is arranged from which, running along the longitudinal direction of the connector, one or more resilient latch flanges with latch tabs are formed that are appropriate for locking onto a ring-shaped groove formed on the inner side of the second connector element (locking position) and in which the first connector element includes an outer directly manually operated sleeve-shaped actuation slide, which can be slid back against a spring force along the longitudinal direction of the connector (unlocking position) and is adapted to actuate one or more sliding supports as locking elements, which can be slid along the longitudinal direction of the connector under a section of the latch flanges and are appropriate for supporting the latch flanges (locking position), characterized in that the latch flanges formed from the latch segment are integrally fixed to an end thereof in a manner ending rearwardly toward the actuation slide, that the sliding supports are formed from an end of the actuation slide and are directed directly toward the free ends of the latch segments, wherein the sliding supports extend from outside of the latch flanges essentially beneath their free ends only, when the actuation slide is pushed forward under the force of the spring.
From the cited patent described above, after the plug and the socket are docked, the actuation slide has to be pushed further in order for inserting the sliding supports beneath the latch flanges, such that the latch tabs are pushed and fastened into the ring-shaped groove, so that the operation of insertion and latching may be accomplished. As a result, cumbersome insertion procedure and complex structure will inhibit rapid connection in use of the conventional connector.
In view of this, the inventor has researched and developed a circular rapid-joint connector in order to improve the above conventional connector with respect to various shortages thereof.

Refer toFigures 16,17,18,19A and 19B, which are schematic diagrams showing assemblage of the invention and a schematic diagram showing another assemblage of the invention. As shown in the figures, in assemblage for the second embodiment, theelastic element 2 may be disposed in the containingarea 11a on the inner edge of the sliding bush 1a, and the buckle holes 12a of the sliding bush 1a are docked with therespective buckles 311a of thesleeve 31a, such that theextension sections 10a and therecession areas 101a of the sliding bush 1a are mated with the respective limitingslots 302a and thebumps 301a mutually. Moreover, the buckle holes 12a of the sliding bush 1a are larger than thebuckles 311a of thesleeve 31a, so that the sliding bush 1a is movable on thesleeve 31a. Moreover, the sliding bush 1a can only move forwards or rearwards, but it cannot move leftwards, rightwards by fitting each of theextension sections 10a, therecession areas 101a, the limitingslot 302a and thebumps 301a. After that, awire 5 is used to penetrate through the lockingbush 33a, theclip 34a, thecollar 32a, the sliding bush 1a and thesleeve 31a for thewire 5 to be connected with each of theinsertion terminals 43 of theconnector plug 4. Then, the secondexternal thread portion 42 of theconnector plug 4 is joined with the firstinternal thread portion 314a of thesleeve 31a, followed by providing thecollar 32a between theelastic pieces 312a on an end of thesleeve 31a for the edge of thecollar 32a to be locked by thestop ring 316a.

Moreover, the clamping characteristic function of theclip 34a may be utilized in practical use, such that it is applicable towires 5, 5a of different diameters. As it is applicable to thewire 5 of a wire diameter having larger diameter, the lockingbush 33a is locked more deeply in conjunction with theclip 34a(as shown inFigure 19A). As it is applicable to thewire 5a of a wire diameter having smaller diameter, the lockingbush 33a is locked shallower in conjunction with theclip 34a (as shown inFigure 19B). As such, the assemblage is accomplished.
Refer toFigures 20 and21, which are a schematic diagram showing operation of the invention, and a schematic diagram showing the invention after insertion with a connection socket. As shown in the figures, the second embodiment may be inserted into acorresponding connection socket 6 in use, while correspond to thesocket body 61 of theconnection seat 6 by theconnector plug 4 in docking, and correspond to the markingportion 63 of theconnection socket 6 by the markingportion 46 of theconnector plug 4, thereby the guidingportion 47 of theconnector plug 4 corresponds to groove 62 of theconnection socket 6 in order to identify insertion direction, such that incorrect insertion is avoided. As thetop portion 41 of theconnector plug 4 is docked tosocket body 61, the periphery of thetop portion 41 will withstand eachbuckle 64 of theconnection socket 6 for eachbuckle 64 to be opened. In the mean time, an end of eachbuckle 64 will abut against the end edge of the sliding bush 1a, such that the sliding bush 1a is pushed toward the holdingunit 3a (rearwards) and compresses theelastic element 2, and be removed from the end edge of the sliding bush 1a after eachbuckle 64 enters theditch 45 of thetop portion 41, while the sliding bush 1a is pushed back toward the top portion 41 (forwards) automatically due to restitution force, such that the sliding bush 1a is locked on the outer edge of eachbuckle 64 of theconnection socket 6 to limit eachbuckle 64 for eachinsertion terminal 43 to be inserted into thesocket body 61, and thereby, to accomplish insertion operation.
In disassembling, the sliding bush 1a is pulled toward the holdingunit 3a (rearwards), such that the sliding bush 1a no longer locked to the outer edge of eachbuckle 64. After that, a force may be applied to disassemble theconnector plug 4 from theconnection socket 6 directly by the user.
Moreover, as the sliding bush 1a moves forwards or rearwards, the sliding bush 1a is mated with the limitingslots 302a andbumps 301a by therespective extension sections 10a andrecession areas 101a, such that the sliding bush 1a is capable of moving forwards or rearwards only, but it is incapable of rotating leftwards or rightwards during movement on thesleeve 31a to maintain its position of the sliding bush 1a accordingly for operation of use thereof to be more stable.
Refer toFigure 22, which is a schematic diagram showing another type of a limiting unit of the invention. As shown in the figure, in addition to the structure described above, the limitingunit 30a of the second embodiment may be also of the structural type in this example, which differs in that the limitingunit 30b comprises arib ring 303b provided on thesleeve 31a, on which multiple insertingslots 304b docked with therespective extension sections 10a are provided. Thereby, theextension sections 10a may be inserted into the respective insertingslots 304b while the sliding bush 1a moves forwards, rearwards. Therefore, the sliding bush 1a is capable of moving forwards, rearwards only, but it is incapable of rotating leftwards, rightwards during movement on thesleeve 31a to maintain the position of the sliding bush 1a accordingly for operation of use thereof to be more stable.
Refer toFigure 23, which is a schematic diagram showing a further type of a limiting unit of the invention. As shown in the figure, in addition to the structure described above, the limitingunits 30a, 30b may also be of the structural type in this example, which differs in that the limitingunit 30c comprises multipleprolonged plates 305c mated with therespective recession areas 101a, and theprolonged plates 305c are formed with arespective groove 306c therebetween for each of theextension sections 10a to mate with. Thereby, theextension sections 10a and therecession areas 101a may be mated with the respectiveprolonged plates 305c andgrooves 306c mutually when the sliding bush 1a moves forwards or rearwards, such that the sliding bush 1a is capable of moving forwards or rearwards only, but it is incapable of rotating leftwards or rightwards during movement on thesleeve 31a to maintain its position of the sliding bush 1a accordingly for operation of use thereof to be more stable.
Refer toFigure 24, which is a schematic diagram showing another type of a clip of the invention. As shown in the figure, in addition to the structure described above, theclip 34a of the second embodiment may be of the structural type in this example, which differs in that an end of theclip 34b has multipleadjacent clamping sheets 341b, and the structure of thenotch portion 342a is omitted in this example. However, the inner edge of the lockingbush 33a may also be used to constrict the outer edge of theclip 34b during operation, such that theclip 34b takes advantage of each of theclamping sheet 341b to form a stable clamping ability on the jacket of thewire 5, such that the applicability to wires of different diameters may also be achieved.
In summary, with the description above, the invention can achieve actually the expected objectives of the invention, such that in assembling, direct docking with the connection socket by the connector plug is available for the connection socket to push away the sliding bush. After the connection socket and the connector plug are snap-fitting, the sliding bush is pushed back by the elastic element automatically, such that the sliding bush is locked to the outer edge of the connection socket to complete operation of assemblage. In disassembling, the sliding bush is pulled backwards such that the sliding bush is not locked to the outer edge of the connection socket any more. After that, a force may be applied to disassemble the connector plug from the connection socket directly, and the fitting of the extension sections, the recession areas and the limiting unit is utilized to limit and prevent the sliding bush from rotation. As a result, the effects of rapid assembling, solid joining, rapid disassembling, simple structure and ease of use are achieved.
