Description

Technical Field

[0001] The utility model belongs to the technical field of cable splitters, and in particular relates to a cable splitter with a cable splitter structure. Background Art

[0002] In the prior art, when a new cable needs to be added to a cable, the previous operation method is generally to wrap the new cable end with the cable, and then roll on insulating tape after the wrapping is completed. This operation process is relatively cumbersome, so a splitter is introduced, which can more conveniently add a new cable to the cable.

[0003] When clamping the cable, the existing splitter generally slides the limit block onto the conductor first, and then locks the limit block with bolts. The limit block bites the exposed part of the cable. Therefore, multiple bolts need to be tightened during wiring, and there is room for further improvement in wiring efficiency.

DETAILED DESCRIPTION

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a cable splitter with a splitting structure, such as Figure 1-3 As shown, it includes two shells 1 connected by a mounting plate 2 and bolts. The inner cavities of the two shells 1 are both provided with conductors 15. Clamping mechanisms are distributed inside the two shells 1. The clamping mechanisms are used to clamp the exposed cable parts without insulation layers. The two parts of the clamping mechanisms distributed inside the two shells 1 are synchronously actuated by a synchronization mechanism; the two parts of the clamping mechanisms in the synchronous action state are used to synchronously clamp the upper and lower parts of the outer wall of the exposed cable, a screw sleeve 3 is formed on the top of the upper shell 1, and a stud 4 is threadedly connected to the inner wall of the screw sleeve 3. The stud 4 and the slide plate 6 are located on the same vertical line, and a sealing ring is provided at the docking position of the two shells 1.

[0021] In this embodiment, when a new cable is connected to the outer wall of the cable, firstly, the insulating rubber of the original outer wall of the cable is partially stripped, and then the insulating rubber of the end of the connected cable is stripped. At this time, the outer shell 1 located at the bottom is placed under the two cable stripping positions, and then the upper outer shell 1 is docked with the lower outer shell 1, and the upper and lower mounting plates 2 are tightened with bolts and nuts;

[0022] After tightening, by rotating the stud 4, the stud 4 moves downward while rotating, driving the clamping mechanism part located above to move downward, and the clamping mechanism part above drives the clamping mechanism located below to move synchronously through the synchronization mechanism, thereby further clamping the exposed part of the cable, thereby achieving an anti-slip effect.

[0023] In a further preferred embodiment of the present invention, Figure 1-3As shown, the clamping mechanism includes a connecting groove 9 opened inside the conductor 15, and a pressure plate 10 is slidably connected inside the connecting groove 9, and a serrated tooth block 11 is formed on the pressure plate 10 near the wire hole of the conductor 15; the two pressure plates 10 and the tooth block 11 are respectively distributed inside the two shells 1, and the synchronization mechanism includes a gear 19 rotatably connected to the inside of the connecting groove 9, and an upper rack 18 extending downward is formed at the bottom end of the upper pressure plate 10, and a lower rack 17 extending upward is formed at the top end of the lower pressure plate 10; the lower rack 17 is meshed with one side of the outer periphery of the gear 19, and the upper rack 18 in a pressed state is meshed with the other side of the outer periphery of the gear 19; a vertical groove 16 for the gear 19 to move is opened on the upper pressure plate 10, and the width of the gear 19 is half the width of the pressure plate 10 and the upper rack 18.

[0024] In this embodiment, after the upper pressing plate 10 moves downward and drives the upper rack 18 to mesh with the gear 19, the upper rack 18 moves downward, driving the gear 19 to rotate, and the gear 19 drives the lower rack 17 to move upward, so that the two pressing plates 10 are close to each other, and the two pressing plates 10 drive the sawtooth tooth blocks 11 to bite the exposed part of the cable, and because the multiple tooth blocks 11 are distributed in a sawtooth shape, the biting force on the exposed part of the cable can be effectively increased to avoid the problem of the cable and the splitter being loosened;

[0025] When the lower rack 17 moves upward, the lower rack 17 will slide with the vertical groove 16, and the vertical groove 16 provides space for the lower rack 17 to move upward, so as to avoid the lower rack 17 from interfering with the pressing plate 10 located above during the movement.

[0026] Furthermore, the width of the vertical groove 16 is half of the pressing plate 10 , so the opening of the vertical groove 16 does not cause the pressing plate 10 located above to be split into two.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, an upper reset mechanism for driving the upper pressure plate 10 to reset is provided on the upper shell 1, and the upper reset mechanism includes a docking hole 5 opened on the shell 1 and its internal conductor 15, and a slide plate 6 is slidably connected to the inner wall of the docking hole 5 up and down, and a connecting column 8 is fixedly connected between the bottom end of the slide plate 6 and the upper pressure plate 10, and an upper spring 7 is connected between the slide plate 6 and the bottom end of the inner wall of the docking hole 5 located above, and a lower reset mechanism for driving the lower pressure plate 10 to reset is provided on the lower shell 1, and the lower reset mechanism includes a guide column 13 formed at the bottom end of the inner wall of the shell 1, and the guide column 13 passes through the lower pressure plate 10, and a fixed plate 12 is integrally formed on the top of the guide column 13, and a lower spring 14 is connected between the bottom end of the fixed plate 12 and the lower pressure plate 10.

[0028] In the present embodiment, when the upper pressure plate 10 moves downward, the pressure plate 10 drives the slide plate 6 to move downward along the docking hole 5 through the connecting column 8. Since the bottom of the upper spring 7 is connected to the docking hole 5, the bottom of the upper spring 7 remains stationary, and the top of the upper spring 7 moves downward, so the upper spring 7 is compressed, and at the same time the connecting column 8 pushes the upper pressure plate 10 to move downward, and after the synchronization mechanism is driven, the pressure plate 10 at the bottom moves upward. Since the top of the lower spring 14 is limited by the fixing plate 12, the top of the lower spring 14 remains stationary, and at the same time the bottom of the lower spring 14 moves upward, so the lower spring 14 is compressed, and since the stud 4 and the screw sleeve 3 are threadedly connected, the threaded connection has self-locking properties, and under the premise that the stud 4 is not rotated, the upper spring 7 and the lower spring 14 will not be reset;

[0029] The upper reset mechanism and the lower reset mechanism are arranged so that the clamping force on the exposed cable position can be adjusted by appropriately rotating the stud 4;

[0030] It should be noted that: in the present application, except for the conductor 15, all other components are made of insulating plastic. At the same time, the rotational connection method of the gear 19 is to rotate with the conductor 15 through an insulating ceramic bearing. Specifically, a hole groove for accommodating insulating ceramics is opened on the conductor 15, and then the outer stator of the insulating ceramic bearing is interference-connected with the hole groove, and then the rotating shaft of the gear 19 is interference-connected with the inner rotor of the insulating ceramic bearing.
