Technical Field
[0001] This utility model relates to the field of wire and cable testing technology, specifically to a cable conductivity testing device. Background Technology
[0002] In the manufacturing process of wires and cables, the conductor, as the core component for transmitting electrical energy or signals, directly determines the quality and safety of the cable. Current conductivity testing procedures require specialized testing equipment to electrically connect both ends of the cable under test, applying a specific voltage or current signal to measure its resistance value to see if it meets standard requirements.
[0003] Currently, when using traditional testing equipment, it is necessary to first strip the insulation from both ends of the cable to be tested to expose the internal core, and then bend the core and electrically connect it to the testing port of the equipment. However, when testing cables with high core stiffness, operators need to spend a lot of time and effort adjusting the core angle to fit the testing port, which seriously reduces testing efficiency.
[0004] Therefore, a cable conductivity testing device is proposed to solve the above problems. Utility Model Content

[0013] Preferably, the conduit has a pre-reserved groove for the piercing cone to pass through, the conduit is fixedly connected to the mounting plate, and the conduit is made of engineering insulating plastic material.
[0014] In the design, the reserved groove on the conduit provides a puncture path for the puncture cone, and the conduit fixedly connected to the mounting plate guides and positions the cable. The conduit is made of engineering insulating plastic to avoid leakage during the testing process.

[0020] This invention improves testing efficiency by setting a fixing mechanism on the device body and a positioning component in the fixing mechanism, and solves the problem that it takes a long time to adjust the core angle when testing cables with high core hardness.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of this utility model is provided: a cable conductivity testing device, including a device body 1, a fixing mechanism 2 installed on the device body 1, and the fixing mechanism 2 is used to fix the cable to be tested;
[0031] The fixing mechanism 2 includes a positioning component 22, on which a conduit 21 is mounted for the cable to be tested to pass through.
[0032] The positioning component 22 includes a mounting plate 221, on which a slide rod 223 is movably mounted via a frame 222. A stainless steel piercing cone 225 is mounted on the slide rod 223. The piercing cone 225 is used to pierce the outer sheath of the cable to be tested.
[0033] Specifically, by setting the fixing mechanism 2 on the device body 1 and the positioning component 22 in the fixing mechanism 2, the detection efficiency is improved, and the problem of long time consumption in adjusting the core angle when testing cables with high core hardness is solved.
[0034] After the cable to be tested passes through the conduit 21, it is stably positioned by the positioning component 22 without the need for manual fixing. When testing is required, the slide bar 223 drives the piercing cone 225 to directly pierce the cable sheath, so that the stainless steel piercing cone 225 contacts the internal wire core, replacing the traditional stripping and wire core bending adjustment steps.
[0035] This design avoids the problem of operators spending a lot of time adjusting the angle to fit the test port due to the high rigidity of the cable core. Electrical continuity is directly achieved through mechanized piercing connection, which simplifies the testing process, shortens the preparation time before testing, and thus significantly improves testing efficiency.
[0036] Example 2
[0037] To achieve stable support for the equipment and coordinated driving of the detection components, such as Figure 1 and Figure 4 As shown, in this embodiment, a base frame 11 is installed at the bottom of the device body 1, an electric push rod 12 is fixedly installed on the front of the device body 1, a connecting plate 121 is fixedly installed on the piston end of the electric push rod 12, and a connecting wire 3 is installed on the device body 1. The connecting wire 3 is used to connect the cable to be tested.
[0038] Specifically, the base frame 11 installed at the bottom of the equipment body 1 provides stable support for the equipment body 1. The electric push rod 12 fixedly installed on the front of the equipment body 1 has the ability to drive the connecting plate 121 to move linearly through the extension and retraction of the piston end. The connecting plate 121 fixedly installed on the piston end of the electric push rod 12 adopts a design that is linked to the slide rod 223. The connecting line 3 installed on the equipment body 1 realizes the function of connecting the equipment body 1 and the cable to be tested.
[0039] Furthermore, the connecting wire 3 passes through the slide bar 223 and is fixedly connected to the piercing cone 225, and the connecting wire 3 is provided with an insulating outer sheath.
[0040] Specifically, the connecting line 3, which passes through the slide bar 223 and is fixedly connected to the puncture cone 225, realizes the function of connecting the device body 1 and the puncture cone 225. The connecting line 3 adopts a composite structure design with an inner conductive core and an outer insulating material.
[0041] Furthermore, a reserved groove 211 is provided on the conduit 21 for the piercing cone 225 to pass through. The conduit 21 is fixedly connected to the mounting plate 221. The conduit 21 is designed with engineering insulating plastic material.
[0042] Specifically, the reserved groove 211 on the conduit 21 provides a piercing path for the piercing cone 225. The conduit 21, which is fixedly connected to the mounting plate 221, guides and positions the cable. The conduit 21 is made of engineering insulating plastic material to avoid leakage during the testing process.
[0043] Example 3
[0044] To achieve automatic reset of the slide bar 223 and structural reinforcement and insulation performance of the positioning assembly 22, such as Figure 2 and Figure 3 As shown, in this embodiment, the frame 222 is provided with a C-shaped opening, and a spring element 224 is fitted on the slide rod 223 located in the C-shaped opening. The spring element 224 is used to reset the slide rod 223. One end of the spring element 224 is elastically connected to the slide rod 223, and the other end of the spring element 224 is elastically connected to the frame 222. The frame 222 and the mounting plate 221 are integrally formed and both are designed with engineering insulating plastic material.
[0045] Specifically, the C-shaped opening on the frame 222 provides installation space for the elastic component 224. The elastic component 224, located inside the C-shaped opening and fitted onto the slide bar 223, has elastic potential energy to push the slide bar 223 back to its original position after it moves. The elastic component 224 is designed to be elastically connected to the slide bar 223 at one end and elastically connected to the frame 222 at the other end. The frame 222 and the mounting plate 221 are integrally formed and both are made of engineering insulating plastic material, which enhances the structural strength and insulation performance of the positioning component 22.
[0046] Furthermore, the end of the slide bar 223 facing away from the puncture cone 225 is fixedly connected to the connecting plate 121, and the slide bar 223 is designed with engineering insulating plastic material.
[0047] Specifically, the structure in which the end of the slide rod 223 away from the puncture cone 225 is fixedly connected to the connecting plate 121 enables the slide rod 223 to move linearly via the electric push rod 12. The slide rod 223 is made of engineering insulating plastic material and is designed to prevent leakage during the detection process.
[0048] When using this utility model, the equipment body 1 is placed on a stable workbench via the bottom frame 11 to ensure equipment stability.
[0049] Take out the cable to be tested, insert one end of it into one end of the conduit 21, and move it along the guide inside the conduit 21 so that the cable passes through the conduit 21.
[0050] The electric push rod 12 is activated, which drives the slide rod 223 to move along the guide structure of the frame 222 towards the cable. The stainless steel piercing cone 225 on the slide rod 223 moves with the slide rod 223, passes through the reserved groove 211 of the conduit 21, pierces the cable sheath, and contacts the internal wire core. At this time, the detection circuit of the equipment body 1 is connected to the cable core through the connecting wire 3, completing the electrical connection.
[0051] The internal detection module of the device body 1 applies a detection voltage or current signal to the cable core through the connecting line 3, collects feedback data in real time, calculates the resistance value, and determines whether the cable conductivity meets the standard.
[0052] After the test is completed, the piston end of the electric push rod 12 retracts, causing the connecting plate 121 and the slide rod 223 to move away from the cable. This causes the piercing cone 225 to exit the cable sheath. After the slide rod 223 has fully reset, the cable is pulled out of the conduit 21, completing a single test process.
