Description

Technical Field

[0001] This utility model relates to the field of DC contactor testing technology, specifically to an installation template for testing DC contactor leads. Background Technology

[0002] Contactors are important power control components used to control the starting and stopping of motors and the switching on and off of other electrical loads. They are widely used in industrial and agricultural electrification and automation, as well as other economic construction fields. Most existing high-voltage DC contactors use coils as their drive units. Therefore, leads are provided at both ends of the coil for users to connect to the power supply and control the contactor's on / off state. Contactors equipped with auxiliary contacts also have leads to provide feedback on the status of the main contacts.

[0003] Currently, for DC contactors with assembled leads, it is usually necessary to connect the corresponding leads sequentially to the corresponding testing equipment for testing. However, traditional testing methods typically involve manually connecting the leads one by one or fixing them with general-purpose clamps before testing. This is not only inefficient but also prone to inaccurate test results due to lead misalignment. Furthermore, the leads are easily damaged when frequently changing testing equipment, thus affecting testing accuracy and equipment lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an installation template for testing DC contactor leads. It overcomes the deficiencies of existing technologies, has a reasonable design, can effectively ensure accurate lead positioning, improve testing efficiency and accuracy, reduce lead damage, extend equipment service life, and ensure the reliability of test results.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An installation template for testing DC contactor leads includes a template body. Multiple wire clamps are installed side-by-side on the front side of the upper surface of the template body. Each wire clamp has a wire clamping groove. A test panel is fixedly installed on the rear side of the upper surface of the template body. Multiple metal contacts are fixedly embedded on the surface of the test panel. Each metal contact corresponds to a wire clamp. The lower end of each metal contact is connected to one end of a lead, and the other end of the lead is fixedly engaged in the corresponding wire clamping groove.

[0007] A placement groove is provided on the rear side of the upper surface of the template body. A winding post is vertically installed on the upper surface of the template body. A wire taking groove is provided on the upper surface of the template body. A first winding post and a first limiting post are provided on the front side of the wire taking groove. A second winding post and a second limiting post are provided on the rear side of the wire taking groove. A gap is reserved between the first winding post and the first limiting post to accommodate the passage of the lead wire. A gap is reserved between the second winding post and the second limiting post to accommodate the passage of the lead wire. The first winding post, the first limiting post, the second winding post, and the second limiting post are all vertically fixedly installed on the template body.

[0008] Preferably, a plurality of wire clamps are also fixedly installed on the upper surface of the template body, and the wire clamps are located between the wire take-up slot and the wire clamp.

[0009] Preferably, a mounting bracket is fixedly installed on the rear side of the upper surface of the template body, and a binding terminal is fixedly installed on the rear side of the mounting bracket.

[0010] Preferably, a support protrusion is fixedly installed at the edge of the upper surface of the template body.

[0011] This invention provides an installation template for testing DC contactor leads, offering the following advantages: By first winding each lead of the DC contactor onto a winding post for initial sorting and guidance, then sequentially inserting each lead into its corresponding clamping slot, and securing it with wire clamps, the template connects each clamping slot to a metal contact point via wires. During testing, the entire template can be directly transported to the testing position. By connecting the metal contacts on the test panel to external testing equipment, the DC contactor can be tested. This avoids misjudgments and effectively improves testing efficiency and accuracy. Furthermore, the entire process eliminates the need for repeated sorting and securing of the DC contactor leads, effectively preventing damage caused by repeated operations when frequently changing testing equipment.

[0016] 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 with reference to the accompanying drawings.

[0017] Example 1, as Figure 1 As shown, an installation template for testing DC contactor leads includes a template body 1. Multiple wire clamps 2 are mounted side-by-side on the front side of the upper surface of the template body 1, each wire clamp having a wire clamping groove 3. A test panel 4 is fixedly mounted on the rear side of the upper surface of the template body 1. Multiple metal contacts 5 are fixedly embedded on the surface of the test panel 4, with each metal contact 5 corresponding to a wire clamp 2. The lower end of each metal contact 5 is connected to one end of a lead, and the other end of the lead is fixedly engaged in the corresponding wire clamping groove 3. The lead is fixedly embedded inside the template body 1. In this embodiment, conductive sheets can be fixedly installed on the inner wall of each wire clamping groove 3, so that the end of the lead is connected to the conductive sheet. Thus, when each lead of the DC contactor is clamped in the wire clamping groove 3 on the wire clamp 2, stable contact between the lead and the conductive sheet is achieved, thereby realizing a one-to-one connection between each lead and each metal contact 5.

[0018] A placement groove 6 is provided on the rear side of the upper surface of the template body 1. A winding post 12 is vertically installed on the upper surface of the template body 1. A wire taking groove 7 is provided on the upper surface of the template body 1. A first winding post 8 and a first limiting post 9 are provided on the front side of the wire taking groove 7. A second winding post 10 and a second limiting post 11 are provided on the rear side of the wire taking groove 7. A gap is reserved between the first winding post 8 and the first limiting post 9 to accommodate the lead wire. A gap is reserved between the second winding post 10 and the second limiting post 11 to accommodate the lead wire. The first winding post 8, the first limiting post 9, the second winding post 10 and the second limiting post 11 are all vertically fixed on the template body 1.

[0019] Working principle:

[0020] During testing, the DC contactor is first placed in the placement slot 6. Then, each lead wire from the DC contactor is first wound around the winding post 12 to initially organize and guide the wires. Next, the leads are sequentially passed through the gaps between the first winding post 8 and the first limiting post 9, and between the second winding post 10 and the second limiting post 11, ensuring the leads are flat and without bends. Afterward, each lead wire is sequentially inserted into its corresponding clamping slot 3, and clamped and fixed using the wire clamp 2. This ensures good contact between each lead wire and the lead wire below the clamping slot 3, achieving precise connection between the lead wire and the metal contact, and ensuring stable transmission of the test signal.

[0021] During subsequent testing, the entire template body 1 can be directly transported to the testing position. By connecting the metal contacts 5 on the test panel 4 to external testing equipment, the DC contactor can be tested. Since each metal contact 5 on the test panel 4 corresponds one-to-one with each lead of the DC contactor, the testing contacts of different testing equipment can directly contact the corresponding metal contacts 5, enabling independent testing of various performance characteristics of the DC contactor. This avoids misjudgments and effectively improves testing efficiency and accuracy. Furthermore, the entire process does not require reorganizing and fixing the leads of the DC contactor, effectively preventing damage to the leads caused by repeated operations when frequently changing testing equipment.

[0022] After the inspection is completed, the gripping fingers of the robotic arm can be controlled to extend downward into the wire take-up slot 7, and then the gripping fingers can be closed to clamp and fix the lead wire. After that, the robotic arm can be directly controlled to pull the lead wire out from the gap between the first winding post 8 and the first limiting post 9, and the second winding post 10 and the second limiting post 11. Then, another robotic arm can be used to take the DC contactor out of the placement slot 6 and transport it to the next process.

[0023] In Embodiment Two, as a further preferred embodiment of Embodiment One, multiple wire clamps 13 are also fixedly installed on the upper surface of the template body 1. The wire clamps 13 are located between the wire take-up slot 7 and the wire clamp 2. In this embodiment, the wire clamps 13 are made of rubber. By providing a wire clamping port on the top of the wire clamp 13, the lead wires are inserted into the wire clamp through the clamping port, thereby achieving further fixation and guidance of each lead wire. This ensures that each lead wire can remain stable in a specific position, preventing displacement due to external forces, and thus ensuring the stability and safety of the overall structure.

[0024] In Example 3, as a further preferred embodiment of Example 1, a mounting bracket 14 is fixedly installed on the rear side of the upper surface of the template body 1, and a binding terminal 15 is fixedly installed on the rear side of the mounting bracket 14.

[0025] Before placing the DC contactor into the placement slot 6, the barcode on the surface of the DC contactor can be scanned and identified. Then, the system binds the DC contact information to the binding terminal 15 on the corresponding template body 1 (this is existing technology and will not be described in detail). Therefore, in the subsequent testing process, only the binding terminal 15 needs to be identified, and the system can automatically retrieve the detailed information of the corresponding DC contactor, simplifying the operation process and improving testing efficiency.

[0026] In Example 4, as a further preferred embodiment of Example 1, a support protrusion 16 is fixedly installed at the edge of the upper surface of the template body 1. During the testing process, to prevent displacement of the template body 1, a telescopic cylinder can be used to drive the template body 1 upward to abut against the corresponding limiting block, forming a stable support. In this embodiment, the support protrusion can be set to buffer the interaction between the template body 1 and the limiting block, thereby effectively reducing the friction of the template body 1 itself, maintaining the structural stability of the template body 1 during long-term use, and extending the service life of the equipment.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
