Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a device for testing the momentary interruption of cables. Background Technology

[0002] As an important carrier for power transmission and information transmission, the operational reliability of cables is directly related to industrial production safety and energy supply stability.

[0003] However, traditional cables do not undergo instantaneous interruption testing, which cannot guarantee the reliability of cable connections and can easily cause equipment connected to the cables to malfunction. Therefore, there is an urgent need for a device for instantaneous interruption testing of cables to solve the above problems.

[0004] For example, during the production, installation and maintenance of cables, it is necessary to test the electrical performance of cables under extreme conditions such as momentary power outage and short circuit to ensure that the products meet industry standards. Cables that have not undergone momentary power outage testing are prone to causing equipment failure. Utility Model Content

[0005] This utility model discloses a momentary interruption test device for cables, which aims to solve the technical problem that traditional cables cannot be used without momentary interruption testing, thus failing to guarantee the reliability of cable connections and easily causing equipment failures in cable connections.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An instantaneous interruption testing device for cables includes a workbench, a cable body, and a clamp mounted on the workbench, and further includes:

[0008] Limiting mechanism: The limiting mechanism is provided on the clamp;

[0009] A connecting plate is provided on one outer wall of the clamp, and a connecting ring is provided on the inner wall of the connecting plate. A connecting port is provided on the limiting mechanism, and a connecting groove is provided on one outer wall of the connecting port. The cable body is limited in the connecting groove. A detector is provided on one side of the top outer wall of the workbench, and two terminals are provided on one outer wall of the detector at equal intervals. The positive and negative poles of the connecting port are respectively provided with connecting wires, and the other ends of the two connecting wires are respectively connected to the positive and negative poles of the terminals.

[0010] In this solution, a limiting mechanism limits the position of the connection port, and then the cable body is connected to the connection slot of the connection port. The positive and negative terminals of the tester and the connection port are electrically connected through the connecting wire, so that the cable body rotates on the inner wall of the circumference of the connecting ring. The connecting ring controls the rotation angle. While the cable body is rotating, the tester detects whether there will be a momentary short circuit, thereby testing the electrical performance of the cable body. The connection is more reliable and the test effect is better.

[0011] In a preferred embodiment, the limiting mechanism includes a threaded rod disposed on the inner wall of the clamp, one end of the threaded rod being provided with a knob, and the other end of the threaded rod being provided with a limiting block, the limiting block being slidably connected to the inner wall of the clamp.

[0012] By adopting the above technical solution, the limiting block moves within the clamp by rotating the threaded rod, and together with the clamp on the other side, the connection port is limited and fixed, adapting to connection ports of different sizes, thereby adapting to the connected cable body. The limiting is simple and the adaptability is better.

[0013] In a preferred embodiment, a fixing buckle is provided on one side of the top outer wall of the fixture, and an installation groove is provided on the bottom outer wall of the fixing buckle. A limiting rod is provided on the inner wall of the installation groove, and the limiting rod is limited between the fixing buckle and the worktable.

[0014] By adopting the above technical solution, the clamp can be fixed at the edge of the worktable to move and fix the position of the clamp. The clamp is fixed between the fixing buckle and the worktable by the limiting rod, which is convenient to use.

[0015] As can be seen from the above, a device for testing the momentary interruption of cables includes a workbench, a cable body, and a clamp mounted on the workbench, and further includes:

[0016] Limiting mechanism: The limiting mechanism is provided on the clamp;

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The present invention discloses a momentary interruption test device for cables, which is mainly used in scenarios where traditional cables are not tested for momentary interruption, thus failing to guarantee the reliability of cable connections and easily causing equipment failures in cable connections.

[0025] Reference Figure 1 and Figure 2 A device for testing the momentary interruption of cables includes a workbench 1, a cable body 5, and a clamp 2 mounted on the workbench 1, and further includes:

[0026] Limiting mechanism: The limiting mechanism is located on fixture 2;

[0027] A connecting plate is provided on one outer wall of the clamp 2, and a connecting ring 6 is fixedly connected to the inner wall of the connecting plate. A connecting port 4 is provided on the limiting mechanism, and a connecting groove 12 is provided on one outer wall of the connecting port 4. The cable body 5 is limited in the connecting groove 12. A detector 3 is provided on one side of the top outer wall of the workbench 1. Two terminals are provided at equal intervals on one outer wall of the detector 3. The positive and negative poles of the connecting port 4 are respectively provided with connecting wires 14, and the other ends of the two connecting wires 14 are respectively connected to the positive and negative poles of the terminals.

[0028] In the specific working process, the limiting mechanism limits the position of the connection port 4, and then the cable body 5 is aligned with the connection groove 12 and electrically connected to the connection port 4. The positive and negative terminals of the detector 3 and the connection port 4 are electrically connected through two connecting lines 14, so that the cable body 5 rotates on the inner wall of the circumference of the connecting ring 6. The connecting ring 6 controls the rotation angle. While the cable body 5 is rotating, the detector 3 detects whether there will be a momentary short circuit, thereby testing the electrical performance of the cable body 5.

[0029] The cable body 5 rotates circumferentially inside the connecting ring 6 and outside the connecting ring 6. By rotating the cable body 5, the cable body 5 is made to move in a circular motion against the inner wall of the connecting ring 6 to check whether the interface is loose and whether the display screen of the connection tester 3 shows any momentary interruption. This simulates the working environment of the cable body 5 and makes it safer to use.

[0030] The cable body 5 is used in conjunction with the detector 3. The cable body 5 is electrically connected to the detector 3 through the connection port 4. The detector 3 detects the momentary interruption of the cable body 5. When the cable line rotates, the detector 3 will show whether there is a momentary short circuit. This method can detect the quality of the cable body 5 and has a better effect.

[0031] It should be noted that: the back of the connection port 4 is provided with multiple positive and negative terminals, and the detector 3 is also provided with multiple positive and negative connection terminals 13. When connecting the connection port 4 and the detector 3 with the connection cable 14, the two can be electrically connected at any position in the vertical direction at the positive and negative terminals, which makes manual operation more convenient.

[0032] Reference Figure 1 and Figure 4 In a preferred embodiment, the limiting mechanism includes a threaded rod 7 provided on the inner wall of the clamp 2, one end of the threaded rod 7 is provided with a knob 8, and the other end of the threaded rod 7 is provided with a limiting block 9, which is slidably connected to the inner wall of the clamp 2.

[0033] Specifically, the connection port 4 is placed in the clamp 2. By rotating the knob 8, the threaded rod 7 is rotated, causing the limiting block 9 to move within the clamp 2 and move closer to the clamp 2 on the other side. This limits and fixes the connection port 4 between the limiting block 9 and the clamp 2, thus adapting to different sizes of connection ports 4 to accommodate the connected cable body 5.

[0034] The connection port 4 is located between the limiting block 9 and the clamp 2. The connection port 4 is placed between the limiting block 9 and the clamp 2. By moving the limiting block 9, the connection port 4 is fixed between the limiting block 9 and the clamp 2.

[0035] The connection port 4 is used in conjunction with the clamp 2. The connection port 4 is fixed on the clamp 2, and the length of the connection port 4 can be controlled. The connection port 4 is limited and fixed by the movement, and the cooperation effect is good.

[0036] Reference Figure 1 and Figure 3 In a preferred embodiment, a fixing buckle 10 is provided on one side of the top outer wall of the clamp 2. The bottom outer wall of the fixing buckle 10 has an installation hole, and a limiting rod 11 is provided on the inner wall of the installation hole. The limiting rod 11 is limited between the fixing buckle 10 and the worktable 1.

[0037] Specifically, the position of the clamp 2 is movable, and the clamp 2 can be fixed at the edge of the workbench 1. It is limited between the fixing buckle 10 and the workbench 1 by the limiting rod 11, thus fixing the clamp 2. The clamp 2 at the edge of the workbench 1 is more conducive to manual operation.

[0038] Working principle: In use, the clamp 2 is placed on the edge of the workbench 1 and fixed between the fixing buckle 10 and the workbench 1 by the limiting rod 11. Then, according to different cable bodies 5, the corresponding connection port 4 is placed. By rotating the knob 8, the threaded rod 7 drives the limiting block 9 to move and fix the connection port 4 between the limiting block 9 and the clamp 2. Then, the cable body 5 is aligned with the connection groove 12 of the connection port 4 and fixed. The positive and negative terminals of the connection port 4 and the detector 3 are electrically connected by the connecting wire 14. At this time, the cable body 5 is rotated in the inner circumference of the connecting ring 6. While rotating, the detector 3 detects whether there is a momentary short circuit in the cable body 5, and then tests the cable body 5.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
