Description

Technical Field

[0001] The utility model relates to the technical field of wires and cables, in particular to a test fixture for the electrical properties of wires. Background Art

[0002] During the production of wires and cables, the electrical properties of the wire are a key indicator of quality. Especially in the field of taping machines, the insulation, conductivity, and voltage resistance of the wire directly impact the safety and reliability of the final product. Therefore, rigorous electrical performance testing of the wire is particularly important.

[0003] A wire electrical performance test fixture is a device specifically used to test the electrical performance of wires. By simulating the use of wires in actual working environments, various electrical performance tests are performed on the wires. The test fixture is usually composed of clamps, connectors, sensors, cables, etc., and can test multiple indicators of the wires, such as resistance, capacitance, inductance, and voltage resistance. In the field of taping machines, the insulation and voltage resistance of wires are particularly important. Poor insulation performance may cause leakage of the wire during use, while insufficient voltage resistance may cause damage to the wire in a high-voltage environment. Therefore, the application of wire electrical performance test fixtures in the field of taping machines is of great significance.

[0004] In the existing technology, the wire is generally tested by a staff member after being placed on the testing equipment and pressing it. This generally wastes manpower and may cause inaccurate test results because the staff cannot accurately place the wire into the test point. At the same time, the pressure of the staff is also unstable. When the pressing force is insufficient, the test results will also be inaccurate. These problems need to be solved. Utility Model Content

[0005] The purpose of the present invention is to provide a test fixture for the electrical properties of wires to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The test fixture for the electrical properties of the wire includes a base, a testing platform, a pressing unit and a locking unit. The base is fixedly mounted on a horizontal table, the testing platform is fixedly mounted on the end surface of the base away from the table, a groove is provided on the surface of the testing platform, the pressing unit is fixedly mounted on the surface of the groove provided on the surface of the testing platform, the pressing unit has pressing and guiding functions, and the locking unit is fixedly mounted on the end surface of the testing platform away from the table.

[0008] The base is used to install and fix the test bench, the pressing unit and the locking unit. The pressing unit is used to press and fix the product on the fixture, and the locking unit is used to maintain the stability of the pressing unit. When the worker puts the wire on the test bench, the pressing unit presses the wire and then tests the electrical performance of the wire. After the locking unit locks the pressing unit, it ensures that the pressing unit will not be pried during the wire test while ensuring stable pressing, preventing the wire from detaching from the test point, thereby ensuring the accuracy of the test results while improving the electrical performance test rate of the wire.

[0009] Furthermore, the pressing unit includes a rotating rod, a mounting block, an extrusion block, a rotating plate, a spring, a buffer block and a guide platform. Both ends of the rotating rod are fixedly mounted on the surfaces on both sides of the groove opened on the detection platform. The rotating plate is rotatably connected to the rotating rod. The mounting block is fixedly mounted on the end of the rotating plate away from the rotating rod. The mounting block is mounted on the surface of the end of the rotating plate away from the desktop. One end of the spring is fixedly connected to the end of the mounting block close to the horizontal desktop. The other end of the spring is fixedly connected to the extrusion block. The buffer block is fixedly connected to the end of the mounting block close to the horizontal desktop through the spring. The guide platform is fixedly mounted on the end of the groove opened on the detection platform close to the horizontal desktop.

[0010] After the staff puts the wire into the testing point in the groove of the testing table, the staff drives the rotating plate to rotate on the rotating rod toward the groove of the testing table by rotating the mounting block. At the same time, the mounting block drives the extrusion block and the buffer block to rotate synchronously until the extrusion block contacts and presses the tail of the wire. The extrusion block compresses the spring to adapt to the size of the wire to avoid crushing the wire. At the same time, the buffer block squeezes the end of the wire into the guide table, thereby guiding the wire and improving the accuracy of the electrical performance test of the wire. It avoids the problems of inaccurate test results and wire crushing caused by unstable pressure caused by manual pressing. At the same time, the buffer block squeezes the spring to avoid crushing the end of the wire.

[0011] Furthermore, the locking unit includes a fixed rod, a rotating rod, a connecting rod and a handle. The fixed rod is vertically fixedly installed on the surface of the test bench at one end away from the horizontal table top. The rotating rod is rotatably connected to the fixed rod. A rectangular slot is provided at the end of the rotating rod away from the fixed rod. Both ends of the connecting rod are fixedly installed on the two side surfaces of the rectangular slot of the fixed rod, and the handle is rotatably installed on the outer surface of the connecting rod.

[0012] When the pressing unit has completed pressing the wire, the staff can rotate the handle around the connecting rod to the required angle according to personal comfort, push the handle to drive the rotating rod to rotate around the fixed rod to the top of the pressing unit, blocking the pressing unit to prevent the pressing unit from tilting while ensuring continuous and stable pressing of the wire to ensure the accuracy of the test results.

[0013] Furthermore, the surface of the base is provided with multiple groups of circular through holes.

[0014] In order to facilitate the assembly of the test line and provide power for the wire test.

[0015] Furthermore, the size of the groove formed on the detection platform is consistent with that of the rotating plate.

[0016] In order to facilitate the rotation of the rotating plate in the groove of the test table, the wire can be pressed while preventing dust from falling into the test port and affecting the accuracy of the test of the wire's electrical properties.

[0017] Furthermore, the mounting block is fixedly connected to the rotating plate by bolts.

[0018] In order to improve the connection stability between the mounting block and the rotating plate, it is convenient for disassembly and installation, and to facilitate subsequent replacement of parts for maintenance.

[0019] Furthermore, the rotating rod is a folded edge structure with a right-angle transition.

[0020] In order to provide a margin when the pressing mechanism presses the wire, the locking unit can provide stable pressure while fitting and locking the pressing unit, so as to avoid inaccurate test results and damage to the wire caused by unstable pressure caused by manual pressing.

[0021] Furthermore, the guide platform is provided with a groove structure having an oblique edge, and the guide platform groove structure is provided with an isosceles trapezoidal boss mechanism.

[0022] In order to make the wire pass through the bevel of the guide table groove quickly and accurately, the wire is guided so that the end of the wire can accurately enter the test point, thereby improving the test accuracy and efficiency.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention drives the extrusion block and the buffer block to rotate synchronously through the installation block in the pressing mechanism, until the extrusion block contacts and presses the tail of the wire, and the extrusion block compresses the spring to adapt to the size of the wire, thereby avoiding damage to the wire. At the same time, the buffer block squeezes the end of the wire into the guide table, thereby achieving the guidance of the wire, improving the accuracy of the electrical performance test of the wire, and avoiding the problems of inaccurate test results and damage to the wire caused by unstable pressure caused by manual pressing.

[0024] The utility model drives the rotating rod to rotate around the fixed rod to above the pressing unit through the handle in the locking mechanism, blocking the pressing unit to prevent the pressing unit from tilting while ensuring continuous and stable pressing of the wire, thereby ensuring the accuracy of the test results.
