Description

Technical Field

[0001] This utility model relates to the field of cable maintenance technology, specifically a cable piercing device for safety testing. Background Technology

[0002] Cables consist of conductive conductors inside and an outer insulating layer. During cable maintenance, a puncture test is typically performed to ensure the cable is not energized. A cable puncture tester can penetrate the high-hardness insulation layer and contact the internal conductors, then a controller connected electrically detects the conductor's energization. Using a puncture tester to inspect cables ensures the safety of electrical maintenance personnel.

[0003] Conventional cable piercing tools require clamping the cable first. However, common clamping components typically consist of two clamps to hold the cable in place. At this point, the cable ends are not secured. When external forces interfere with the cable ends, the cable can easily twist or roll, making it difficult for the two clamps alone to hold it stably. Consequently, during the piercing process, it becomes impossible to accurately contact the internal conductors of the cable, requiring multiple piercings to achieve the desired result, causing significant inconvenience to the user. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a piercing device for safety testing cables.

[0005] The technical solution of this utility model is as follows: a piercing device for safety testing cables, comprising a positioning component, a piercing gun, and a controller. The positioning component is detachably connected to one end of the piercing gun, and the other end of the piercing gun is electrically connected to the controller via a wire. The positioning component includes a crossbar and a clamping component. Detachable clamping components are provided on both sides of the crossbar. The clamping component includes an upper arc plate and a lower arc plate. One side of the upper arc plate and the lower arc plate are connected by a hinge, and the other side is provided with a locking mechanism. Detachable elastic pads are provided on the contact surfaces of the upper arc plate and the lower arc plate with the cable.

[0006] Furthermore, the upper arc plate is provided with a stud, and the crossbar is provided with a through hole that matches the stud; one end of the stud is integrated with the upper arc plate, and the other end passes through the through hole and is provided with a locking nut.

[0007] Furthermore, the elastic pad has multiple protrusions on the side near the clamping assembly, and the clamping assembly has positioning grooves that match the protrusions.

[0008] Furthermore, the side of the elastic pad that contacts the cable has anti-slip texture.

[0009] Furthermore, the locking mechanism includes a screw and a notch. The side of the lower arc plate away from the hinge is rotatably connected to one end of the screw, and the other end of the screw is provided with a threaded wing nut. The side of the upper arc plate away from the hinge is provided with a notch that matches the screw.

[0010] Furthermore, the piercing gun includes a barrel and a chamber, with the barrel and chamber fixedly connected by a connecting nut; an internally threaded cylinder is fitted onto one end of the barrel near the positioning assembly, and an externally threaded cylinder that matches the internally threaded cylinder is provided in the middle of the crossbar.

[0011] Furthermore, the controller is equipped with a delay button, indicator lights, and a speaker.

[0012] Compared with existing technologies, the advantages of this invention are as follows: the clamping components on both sides of the crossbar clamp a section of cable, keeping the cable stable between the clamping components, and the piercing gun pierces a section of cable within the clamping area. The upper and lower arc plates correspond to the shape of the cable, allowing for better clamping. The elastic deformation of the elastic pad ensures an interference fit between the cable and the clamping components, further improving clamping stability. The detachable clamping components are easy to replace to accommodate cables of different diameters. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0021] like Figures 1-4 As shown, a cable piercing device for safety testing includes a positioning component 1, a piercing gun 2, and a controller 3. The positioning component 1 is detachably connected to one end of the piercing gun 2, and the other end of the piercing gun 2 is electrically connected to the controller 3 via a wire 24. The piercing gun 2 determines the piercing position on the cable through the positioning component 1, and the controller 3 can send a signal to the piercing gun 2 to trigger piercing or display the energization status of the cable.

[0022] The positioning component 1 includes a crossbar 11 and a clamping component 12. Detachable clamping components 12 are provided on both sides of the crossbar 11. Each clamping component 12 includes an upper arc plate 121 and a lower arc plate 122. One side of the upper arc plate 121 and the lower arc plate 122 are connected by a hinge, and the other side has a locking mechanism. A stud 123 is provided on the upper arc plate 121, and a through hole is provided on the crossbar 11 to mate with the stud 123. One end of the stud 123 is integrated with the upper arc plate 121, and the other end passes through the through hole and is equipped with a locking nut 124. The upper arc plate 121 and the lower arc plate 122 can conform to the shape of the cable, providing stable clamping. The clamping component 12 is fixedly connected to the crossbar 11 by the locking nut 124. When it is necessary to clamp cables of different diameters, the locking nut 124 can be released to replace the clamping component 12 with one that matches the cable size, thus maintaining stable clamping. Both the upper arc plate 121 and the lower arc plate 122 have removable elastic pads 14 on their contact surfaces with the cable. The side of the elastic pad 14 closest to the clamping assembly 12 has multiple protrusions 141, and the clamping assembly 12 has positioning grooves 143 that mate with the protrusions 141. During the clamping process, the clamping assembly 12 deforms the elastic pad 14, utilizing the elastic force of the deformation to improve the clamping effect on the cable. The side of the elastic pad 14 that contacts the cable has anti-slip textures 142, which reduce the tendency for the cable to rotate during clamping.

[0023] The locking mechanism includes a screw 125 and a notch 127. The side of the lower arc plate 122 away from the hinge is rotatably connected to one end of the screw 125, and the other end of the screw 125 is provided with a threaded wing nut 126. The end of the upper arc plate 121 away from the hinge is provided with a notch 127 that mates with the screw 125. The cable enters from the side of the clamping assembly 12 away from the hinge between the upper arc plate 121 and the lower arc plate 122. The upper arc plate 121 and the lower arc plate 122 are closed, and the screw 125 is rotated to the notch 127. The wing nut 126 is tightened, so that the upper arc plate 121 and the lower arc plate 122 apply a clamping force to the cable.

[0024] The piercing gun 2 includes a barrel 21 and a chamber 23. The barrel 21 and the chamber 23 are fixedly connected by a connecting nut 22. One end of the chamber 23 is provided with a pull ring 231. An internally threaded cylinder 211 is fitted onto the end of the barrel 21 near the positioning component 1. An externally threaded cylinder 111 that mates with the internally threaded cylinder 211 is provided in the middle of the crossbar 11. The piercing gun 2 and the crossbar 11 are fixedly connected by the mating of the internally threaded cylinder 211 and the externally threaded cylinder 111. The chamber 23 is filled with nail cartridges, and then the barrel 21 and the chamber 23 are fixedly assembled by the connecting nut 22. The controller 3 is electrically connected to the chamber 23. Pull out the pull ring 231 and wait for the controller 3 to issue a piercing signal. Pressing the delay button 32 on the controller 3 will illuminate the indicator light 321. The speaker 33 on the controller 3 will then emit an audible signal instructing the operator to move away from the site. After the operator has moved to a safe distance, the controller will issue a puncture command to the puncture gun 2. Once the puncture is complete, the speaker 33 will signal to the operator that the puncture test is finished. The controller 3 has multiple connectors 31 for simultaneous electrical connection to multiple puncture guns 2, allowing for multiple puncture tests to be performed simultaneously, thus improving testing efficiency.

[0025] The working principle of this utility model is as follows: Select a suitable clamping assembly 12 according to the cable diameter. Pass the stud 123 of the upper arc plate 121 through the through hole on the crossbar 11 and tighten the locking nut 124 to assemble the clamping assembly 12 onto the crossbar 11. Insert both ends of the cable into the clamping assembly 12 from the side of the upper arc plate 121 and lower arc plate 122 away from the hinge. Rotate the screw 125 to the notch 127 of the upper arc plate 121, and then tighten the wing nut 126 to apply clamping force to the cable using the upper arc plate 121 and lower arc plate 122. The operation of the piercing gun 2 is controlled by the controller 3.
