Description

Technical Field

[0001] The utility model relates to the technical field of power-on testing, in particular to a cable power-on testing tool. Background Art

[0002] A cable is a device for transmitting electrical energy, usually consisting of several or several groups of wires that are insulated from each other and usually twisted around a center wire and covered with a highly insulating covering. The main function of the cable is to transmit electricity or information from one place to another.

[0003] After the cable is produced, it is often necessary to conduct a power-on test. The cable conductor is connected to another conductor and then a power-on test is conducted. In order to save trouble, some workers directly connect the heads of the two conductors together, and then simply wrap them with simple insulating tape to connect the two conductors and power them on. Although this method is simple, it is full of dangers. When power is turned on, once sparks are generated at the connection of the wires, sparks will fly and may endanger people around. There are great safety hazards and this fixing method is also more troublesome. The tape needs to be fully untied when separating, which is not convenient at all. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A cable power-on test tool comprises a base 1, a protective shell 2 is placed on the upper surface of the base 1, a fixing frame 4 is vertically arranged in the middle of the upper surface of the base 1, a power-on unit 3 is arranged on the upper end of the fixing frame 4, and fixing boxes 5 are symmetrically arranged on both sides of the fixing frame 4 on the upper surface of the base 1, and a limit rod 6 is rotatably arranged on the fixing box 5;

[0022] A plug hole 51 is provided in the body of the fixed box 5, and a power block 7 is provided at the top of the plug hole 51. A movable groove 52 is provided at the upper end of the hole wall of the plug hole 51 on the side of the power block 7, and a clamping block 53 is provided in the movable groove 52. A threaded hole 54 is provided in the middle of the top wall of the movable groove 52, and the threaded hole 54 is opened to the upper surface of the body of the fixed box 5.

[0023] Among them, a threaded portion that engages with the threaded hole 54 is opened on the rod body of the limiting rod 6. The limiting rod 6 can rotate in the threaded hole 54, and the bottom end surface of the rod body of the limiting rod 6 abuts against the upper surface of the clamping block 53. As the limiting rod 6 rotates downward, the clamping block 53 can be slowly pressed downward.

[0024] In addition, a second spring 531 is symmetrically connected to the upper surface of the clamping block 53. The second spring 531 is fixed to the top groove wall of the movable groove 52 at one end away from the clamping block 53. The second spring 531 facilitates the clamping block 53 to always be against the bottom end of the limiting rod 6 after the limiting rod 6 rotates upward.

[0025] Moreover, a slot 11 is provided at a side edge of the upper surface of the base 1 , and the protective shell 2 is inserted and installed in the slot 11 . The slot 11 is convenient for installing and fixing the protective shell 2 .

[0026] At the same time, the power-on block 7 extends to the outside of the fixed box 5, the power-on blocks 7 on the fixed boxes 5 on both sides are relative, and the power-on blocks 7 on both sides are in contact with the power-on unit 3 above. The power-on unit 3 includes a push rod 31, and the push rod 31 is arranged on the fixed frame 4 for up and down movement. The bottom end of the push rod 31 is horizontally fixedly connected with a conductive touch plate 33, and the contact at the bottom end of the conductive touch plate 33 can contact the power-on blocks 7 on both sides. The upper end of the conductive touch plate 33 is fixedly connected with a first spring 32, and one end of the first spring 32 away from the conductive touch plate 33 is fixed on the bottom surface of the upper frame of the fixed frame 4. The conductive touch plate 33 can electrically connect the power-on blocks 7 on both sides, so as to perform a power-on test.

[0027] In this embodiment, when it is necessary to conduct a power-on test on the cable, this test tool can be used. First, the wires at the cable head are exposed, and then the cable is inserted into the fixing box 5 on one side, and the cable is inserted into the jack 51, and the cable is pushed to the innermost side, and then the limit rod 6 is rotated. As the limit rod 6 rotates downward, the clamping block 53 below can move downward in the movable groove 52, so that the clamping block 53 can slowly clamp the wire head of the cable until the clamping is completed, and then the rotation of the limit rod 6 is stopped, and then another energized wire is installed into the fixing box 5 in the same way.

[0028] Then the protective shell 2 can be covered and inserted into the slot 11. Then the operator wears insulating gloves, holds the push rod 31, and pushes the push rod 31 downward on the fixing frame 4 so that the conductive touch plate 33 at the bottom can contact the power-on blocks 7 on both sides. Then the wire can be energized, and the current is transmitted from the conductive touch plate 33 to the power-on block 7 on one side of the wire, and then to the cable for a power-on test. Once a spark appears in the middle, the operator immediately cuts off the power and releases the push rod 31. Under the elastic contraction of the first spring 32, the push rod 31 can be reset, and the conductive touch plate 33 is reset to the top of the power-on block 7. When sparks are generated, the protective shell 2 can effectively prevent sparks from flying.

[0029] When removing the wires on both sides, it is only necessary to rotate the limit rod 6 upward. The second spring 531 can keep the clamping block 53 always against the bottom end of the limit rod 6 after the limit rod 6 is rotated upward, so that the clamping block 53 can slowly disengage from the wire of the cable.

[0030] Moreover, the push rod 31, the limit rod 6 and the box body of the fixing box 5 are all made of insulating materials to ensure the safety of the equipment.

[0031] In the utility model, by installing the protective shell 2 on the base 1, it can be ensured that once sparks are generated during the power-on test, the sparks will not endanger external operators, thereby ensuring its safety. In addition, the provided fixing box 5 is convenient for fixing the cable. The cable can be quickly fixed by only rotating the limit rod 6 downward and pressing the clamping block 53 against the cable conductor. When disassembling, it is only necessary to rotate the limit rod 6 upward and cooperate with the second spring 531 to quickly disengage the clamping block 53, making it more convenient to disassemble and install the cable.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
