Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering, and in particular to a detection device for intermediate joints of low-voltage cables. Background Technology

[0002] Low-voltage circuits generally refer to DC circuits or audio, video, network, and telephone lines, with AC voltage typically below 36V. Low-voltage debugging equipment is used to detect, test, and adjust low-voltage systems and related equipment to ensure their normal, stable, and efficient operation. The intermediate joints of low-voltage cables are a crucial component of the cable system, and their quality directly affects the stability and reliability of the entire system. To ensure the quality of low-voltage cable intermediate joints, a series of rigorous tests are required. These tests include visual inspection, contact reliability testing, power-off testing, power-on testing, time-domain reflectometry, cable body damage inspection, joint cleanliness and sealing inspection, splicing quality inspection, and joint marking inspection.

[0003] In existing technologies, some low-voltage cable joint testing devices require the low-voltage cable joint to be placed into a V-shaped groove in the lower pressure plate before use. Then, the drive cylinder is activated to move the upper pressure plate towards the lower pressure plate to clamp the low-voltage cable joint. Next, the moving cylinder is activated to move the test rod to contact the low-voltage cable joint. Finally, the test rod is energized through the cable to perform an energization test on the low-voltage cable joint. Because the center point of the low-voltage cable joint will move up and down after being placed in the V-shaped groove, the center of the fixed low-voltage cable joint is not on the same horizontal line as the center line of the test rod. Therefore, it is necessary to align the low-voltage cable joint with the test rod, which greatly reduces the testing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a detection device for intermediate joints of low-voltage cables. This solves the problem mentioned in the background art where the center point of the intermediate joint of the low-voltage cable moves up and down after being placed in the V-shaped groove, causing the center of the fixed intermediate joint of the low-voltage cable to be out of sync with the center line of the test rod. Therefore, additional alignment of the intermediate joint of the low-voltage cable with the test rod is required, which greatly reduces the efficiency of the test.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a detection device for intermediate joints of low-voltage cables, including a base; A connecting frame is fixedly installed on the top of the base. The surface of the connecting frame has several insertion holes. The surface of the connecting frame has several second sliding holes, first sliding holes, and third sliding holes around the insertion holes. The second sliding holes, first sliding holes, and third sliding holes are alternately arranged on the surface of the connecting frame. A first clamping seat is slidably connected in one of the first sliding holes, and a second clamping seat is slidably connected in the remaining first sliding holes. A first transmission seat is slidably connected in the second sliding hole, and a second transmission seat is slidably connected in the third sliding hole. A clamping cylinder is fixedly connected to the bottom end of the first clamping seat. The test component is located at the top of the base.

[0006] Optionally, the test assembly includes a guide rail, a mounting base, a movable cylinder, and a test rod. The guide rail is fixedly installed on the top of the base on one side of the connecting frame. The mounting base is slidably connected to the surface of the guide rail. The movable cylinder is fixedly installed on the top of the base on one side of the guide rail. The movable cylinder and the mounting base are fixedly connected. The test rod is disposed inside the mounting base.

[0007] Optionally, both the first transmission seat and the second transmission seat are L-shaped on one side, and the first transmission seat and the second transmission seat are arranged intersectingly within the first clamping seat and the second clamping seat.

[0008] Optionally, both the first clamping seat and the second clamping seat have a clamping plate fixedly connected to one end near the insertion hole, and the clamping plate is arc-shaped.

[0009] Optionally, a protective sleeve is provided on the surface of the clamping plate, and the surface of the protective sleeve is provided with anti-slip texture.

[0010] Optionally, a fixing plate is provided at the top of the mounting base, a fixing bolt is inserted inside the fixing plate, and a fixing nut is threaded onto the surface of the fixing bolt.

[0011] Optionally, an elastic washer is fitted onto the surface of the fixing bolt, and the elastic washer is annular.

[0012] Optionally, a cable management plate is fixedly connected to the top of the mounting base on one side of the test rod, and the corners of the cable management plate are rounded.

[0013] The beneficial effects of this utility model are as follows: the intermediate connector of the low-voltage cable is placed into the socket, and the intermediate connector of the low-voltage cable can be clamped and fixed by cooperating with the clamping cylinder, the first clamping seat, the first sliding hole, the first transmission seat, the second transmission seat, the second sliding hole, the third sliding hole and the second clamping seat. Since the first clamping seat and the second clamping seat can move simultaneously toward the intermediate connector of the low-voltage cable, it ensures that the center of the clamped intermediate connector of the low-voltage cable is on the same horizontal line as the center of the test rod, which helps to improve the efficiency of fixing the intermediate connector of the low-voltage cable. The test rod located within the mounting base can be maintained by using fixing nuts, fixing bolts, and fixing plates, ensuring the accuracy of the test results. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1 to 3This utility model provides a technical solution: a detection device for intermediate joints of low-voltage cables, comprising: a base 1, a connecting frame 2 fixedly installed at the top of the base 1, a plurality of insertion holes 201 formed on the surface of the connecting frame 2, a plurality of second sliding holes 203, first sliding holes 202 and third sliding holes 204 formed around the insertion holes 201 on the surface of the connecting frame 2, the second sliding holes 203, first sliding holes 202 and third sliding holes 204 being alternately arranged on the surface of the connecting frame 2, and a first clamping seat 205 being slidably connected in one of the first sliding holes 202. The second clamping seat 206 is slidably connected in the first sliding hole 202, the first transmission seat 207 is slidably connected in the second sliding hole 203, the second transmission seat 208 is slidably connected in the third sliding hole 204, the clamping cylinder 209 is fixedly connected to the bottom end of the first clamping seat 205, and the test component 3 is provided at the top of the base 1. The first transmission seat 207 and the second transmission seat 208 are both L-shaped on one side, and the first transmission seat 207 and the second transmission seat 208 are arranged crosswise in the first clamping seat 205 and the second clamping seat 206.

[0017] The weak current cable intermediate joint is placed into the insertion hole 201 on the surface of the connecting frame 2. Then, the clamping cylinder 209 is activated, causing the first clamping seat 205 to slide along one of the first sliding holes 202 on the surface of the connecting frame 2 toward the weak current cable intermediate joint. This causes the first transmission seat 207 and the second transmission seat 208, which are slidably connected inside, to slide along the second sliding hole 203 and the third sliding hole 204 on the surface of the connecting frame 2, respectively. This, in turn, causes several second clamping seats 206 to slide along the remaining first sliding holes 202, thereby clamping and fixing the weak current cable intermediate joint. Since the first clamping seat 205 and the second clamping seat 206 can move toward the weak current cable intermediate joint at the same time, it ensures that the center of the clamped weak current cable intermediate joint is on the same horizontal line as the center of the test rod 304, which helps to improve the efficiency of fixing the weak current cable intermediate joint.

[0018] Preferably, the first clamping seat 205 and the second clamping seat 206 are both fixedly connected to a clamping plate 210 near the insertion hole 201, and the clamping plate 210 is arc-shaped.

[0019] The curved shape of the clamp 210 allows it to fit more closely to the surface of the low-voltage cable joint, thereby further improving the fixing effect of the low-voltage cable joint.

[0020] Furthermore, a protective sleeve 211 is fitted onto the surface of the clamp 210, and the surface of the protective sleeve 211 is provided with anti-slip texture.

[0021] The protective sleeve 211 not only prevents the clamp 210 from scratching the intermediate joint of the low-voltage cable, but also increases the friction between the intermediate joint of the low-voltage cable and the clamp 210, which helps to enhance the fixing effect of the clamp 210 on the intermediate joint of the low-voltage cable.

[0022] Please see Figure 4 The present invention provides a technical solution: the test component 3 includes a guide rail 301, a mounting base 302, a moving cylinder 303 and a test rod 304. The guide rail 301 is fixedly installed on the top of the base 1 on one side of the connecting frame 2. The mounting base 302 is slidably connected to the surface of the guide rail 301. The moving cylinder 303 is fixedly installed on the top of the base 1 on one side of the guide rail 301. The moving cylinder 303 and the mounting base 302 are fixedly connected. The test rod 304 is disposed in the mounting base 302.

[0023] The movable cylinder 303 is activated, causing the mounting base 302 to slide along the surface of the guide rail 301, which in turn drives the test rod 304 installed in the mounting base 302 to connect to the intermediate joint of the low-voltage cable. At this time, the intermediate joint of the low-voltage cable can be tested by energizing the test rod 304 through the cable connected to one end of the test rod 304.

[0024] Preferably, a fixing plate 305 is provided at the top of the mounting base 302, a fixing bolt 306 is provided inside the fixing plate 305, and a fixing nut 307 is threaded onto the surface of the fixing bolt 306.

[0025] Rotating the fixing nut 307 to disengage it from the fixing bolt 306 allows the fixing plate 305 to be removed from the top of the mounting base 302, enabling maintenance of the test rod 304 located inside the mounting base 302 and ensuring the accuracy of the test results.

[0026] Furthermore, an elastic washer 308 is fitted on the surface of the fixing bolt 306, and the elastic washer 308 is annular.

[0027] When the fixing bolt 306 is tightened, the elastic washer 308 will deform due to the compression of the fixing bolt 306, thereby preventing the fixing bolt 306 from loosening and improving the firmness of the connection between the mounting base 302 and the fixing plate 305.

[0028] Optionally, a cable management plate 309 is fixedly connected to the top of the mounting base 302 on one side of the test rod 304, and the corners of the cable management plate 309 are rounded.

[0029] The cable management plate 309 can separate the lines connected to the test rod 304, thereby preventing the lines from getting tangled. The corners of the cable management plate 309 are rounded to prevent them from scratching the lines.

[0030] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
