Description

Technical Field

[0001] This utility model relates to the field of lead wire splice technology, and more specifically to a lead wire splice for live working. Background Technology

[0002] Lead wire connectors, also known as parallel groove clamps, are used to connect small and medium cross-section aluminum stranded wires or steel-cored aluminum stranded wires and steel stranded wires of overhead lightning protection wires in positions where they are not subjected to tension. They are also used for jumper connections of non-straight towers. The lead wire connector consists of three parts: an upper clamp, a lower clamp, and a bolt. During daily storage or transportation, in order to prevent the parts from falling off, the upper clamp and the lower clamp are fastened to the bolt with nuts. When using it, the operator needs to loosen the nuts first to separate the upper clamp and the lower clamp, which is inconvenient. Therefore, it is urgent to design a lead wire connector for live working to solve the above problems. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a live-line working lead connector to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a live working lead wire splicer, including an upper clamp, a lower clamp, and a screw assembly. The upper clamp and the lower clamp are slidably sleeved on the screw assembly. It also includes a locking component, which is located at the bottom of the lower clamp and can lock the lower clamp onto the screw assembly.

[0005] Furthermore, the screw assembly includes a horizontal plate, two bolts, and two nuts. The two bolts are fixedly installed on the top of the horizontal plate, and the two nuts are respectively slidably sleeved on the two bolts by threads. The upper clamp and the lower clamp are slidably sleeved between the two bolts.

[0006] Furthermore, the locking assembly includes a base and two locking blocks. The base is fixedly installed on the bottom of the lower clamp. A sliding groove is provided on the bottom of the base. The two locking blocks are symmetrically slidably installed in the sliding groove. The base is slidably sleeved between two bolts through the sliding groove, and the locking blocks can be slidably locked in the bolts.

[0007] Furthermore, both bolts are provided with slots, and the locking blocks are slidably installed in the slots.

[0008] Furthermore, the locking assembly also includes a rotating rod, an elliptical plate, and two connecting blocks. The rotating rod is rotatably installed in the lower clamp, the elliptical plate is fixedly installed on the rotating rod, and the two connecting blocks are respectively fixedly installed on the bottom of the two locking blocks. Two arc-shaped grooves are equidistantly formed on the circumference of the elliptical plate, and the two connecting blocks are respectively slidably installed in the two arc-shaped grooves.

[0009] Furthermore, the locking assembly also includes a hexagonal rod, a paddle, and a spring. The bottom of the rotating rod has a hexagonal groove, the hexagonal rod is slidably installed in the hexagonal groove, the paddle is fixedly installed at the bottom of the hexagonal rod, one end of the spring is fixedly installed in the hexagonal groove, and the other end of the spring is fixedly installed at the top of the hexagonal rod.

[0010] Furthermore, the screw assembly also includes two concave blocks, both of which are fixedly installed at the bottom of the horizontal plate, and the paddle is slidably installed between the concave parts of the two concave blocks.

[0011] Furthermore, the locking assembly also includes four limiting blocks, which are fixedly installed at both ends of the two locking blocks respectively. Limiting grooves are provided at both ends of the base, and the limiting blocks are slidably installed in the limiting grooves.

[0012] The technical effects and advantages of this utility model are as follows: Before installation, this invention allows for unlocking by pulling down the lever and hexagonal rod to disengage the lever from the two concave blocks. Rotating the lever and hexagonal rod counter-clockwise then causes the rotating rod and elliptical plate to rotate counter-clockwise. This counter-clockwise rotation of the elliptical plate causes the two connecting blocks to slide closer together, thereby pulling the two locking blocks closer together and disengaging them from their slots, thus unlocking the lower clamp. Sliding the lower clamp downwards to separate it from the upper clamp allows the cable to be placed between the upper and lower clamps, improving the ease of separation for workers.

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0016] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 6 The present invention will be further described below.

[0017] The live-line working lead splice includes an upper clamp 1, a lower clamp 2, and a screw assembly 3. Both the upper clamp 1 and the lower clamp 2 are slidably sleeved on the screw assembly 3. It also includes a locking assembly 4, which is located at the bottom of the lower clamp 2 and can lock the lower clamp 2 onto the screw assembly 3.

[0018] Specifically, the screw assembly 3 includes a horizontal plate 301, two bolts 302, and two nuts 305. The two bolts 302 are fixedly installed on the top of the horizontal plate 301, and the two nuts 305 are respectively threaded and slidably sleeved on the two bolts 302. The upper clamp 1 and the lower clamp 2 are slidably sleeved between the two bolts 302.

[0019] In this embodiment, in the initial state, the lower clamp 2 is locked to the two bolts 302 by the locking assembly 4, and the upper clamp 1 is attached to the lower clamp 2 and limited by the nut 305.

[0020] Specifically, the locking assembly 4 includes a base 401 and two locking blocks 403. The base 401 is fixedly installed at the bottom of the lower clamp 2. A sliding groove 402 is provided at the bottom of the base 401. The two locking blocks 403 are symmetrically slidably installed in the sliding groove 402. The base 401 is slidably sleeved between two bolts 302 through the sliding groove 402. The locking blocks 403 can be slidably locked in the bolts 302. Both bolts 302 are provided with locking slots 303. The locking blocks 403 are slidably installed in the locking slots 303.

[0021] In this embodiment, in the initial state, the locking block 403 is in the slot 303, locking the base 401 onto the bolt 302.

[0022] Specifically, the locking assembly 4 also includes a rotating rod 404, an elliptical plate 405, and two connecting blocks 407. The rotating rod 404 is rotatably installed in the lower clamp 2, the elliptical plate 405 is fixedly installed on the rotating rod 404, and the two connecting blocks 407 are respectively fixedly installed on the bottom of the two locking blocks 403. Two arc-shaped grooves 406 are equidistantly formed on the circumference of the elliptical plate 405, and the two connecting blocks 407 are respectively slidably installed in the two arc-shaped grooves 406.

[0023] In this embodiment, when the elliptical plate 405 rotates counterclockwise, it will cause the two arc-shaped grooves 406 to rotate counterclockwise. When the two arc-shaped grooves 406 rotate counterclockwise, they will cause the two connecting blocks 407 to slide along the inner wall of the arc-shaped grooves 406, thereby causing the two connecting blocks 407 to slide closer to each other.

[0024] Specifically, the locking assembly 4 also includes a hexagonal rod 411, a lever 412, and a spring 413. The bottom of the rotating rod 404 is provided with a hexagonal groove 410. The hexagonal rod 411 is slidably installed in the hexagonal groove 410. The lever 412 is fixedly installed at the bottom of the hexagonal rod 411. One end of the spring 413 is fixedly installed in the hexagonal groove 410, and the other end of the spring 413 is fixedly installed at the top of the hexagonal rod 411. The screw assembly 3 also includes two concave blocks 304. Both concave blocks 304 are fixedly installed at the bottom of the horizontal plate 301. The lever 412 is slidably installed between the concave parts of the two concave blocks 304.

[0025] In this embodiment, in the initial state, the spring 413 is in a contracted state, applying a pulling force to the hexagonal rod 411 and the paddle 412, so that the paddle 412 is between the concave parts of the two concave blocks 304, thereby locking the paddle 412.

[0026] Specifically, the locking assembly 4 also includes four limiting blocks 409, which are fixedly installed at both ends of the two locking blocks 403 respectively. Limiting grooves 408 are provided at both ends of the base 401, and the limiting blocks 409 are slidably installed in the limiting grooves 408.

[0027] In this embodiment, the limiting block 409 and the limiting groove 408 can limit the locking block 403 to prevent it from falling off the slide groove 402.

[0028] Working principle: Before installation, first pull down the lever 412 and the hexagonal rod 411 to disengage the lever 412 from the two concave blocks 304, thus unlocking the lever 412. Then, rotate the lever 412 and the hexagonal rod 411 counterclockwise, causing the rotating rod 404 and the elliptical plate 405 to rotate counterclockwise. When the elliptical plate 405 rotates counterclockwise, it will cause the two connecting blocks 407 to slide closer to each other in the two arc-shaped grooves 406, thereby causing the two locking blocks 403 to move closer to each other and disengage from the locking grooves 303, thus unlocking the lower clamp 2. At this time, the lower clamp 2 can be slid down to separate it from the upper clamp 1. Slide the lower clamp 2 down until the elliptical plate 405 contacts the horizontal plate 301. Then, place the cable between the upper clamp 1 and the lower clamp 2. Then, slide the upper clamp 1 down until it contacts the cable, and then tighten the two nuts 305 to complete the installation.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
