Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, specifically relating to a spring terminal clamping tool. Background Technology

[0002] Radio frequency (RF) power supplies typically use spring-loaded terminals for electrical connections. Currently, the installation of these spring-loaded terminals mainly relies on manual operation, where the terminals are manually pressed into their corresponding sockets. This requires considerable force during insertion, making the operation laborious and prone to hand injuries. Furthermore, the confined space inside the RF power supply makes this even more difficult, further increasing the installation complexity and increasing the risk of hand injuries due to improper force application.

[0003] Furthermore, when there is a repair task, the process of removing the spring-loaded terminal is more difficult. There is a large insertion and extraction force between it and the socket, making it difficult to remove smoothly in a confined space by hand alone. If conventional tools such as pliers are used for assistance, it is easy to damage the spring-loaded terminal or break the corresponding socket, thereby affecting the reliability of the electrical connection and bringing additional maintenance costs and equipment risks. Utility Model Content

[0004] The purpose of this utility model is to provide a spring terminal clamping tool, which solves the technical problems of manual insertion and removal of spring terminals using conventional tools, which are laborious and easy to injure hands, difficult to operate in a narrow space, and easy to damage the terminals and sockets.

[0005] This utility model discloses a spring terminal clamping tool, comprising: two clamping arms arranged in a cross configuration, each clamping arm comprising a handle section, a transition section, and a clamping section in sequence; the transition sections of the two clamping arms are attached to each other and rotatably connected by a pivot, so that the two clamping arms can rotate around the pivot as a fulcrum; The two clamping segments have opposing clamping blocks at their ends, and the opposing sides of the clamping blocks are provided with receiving grooves for accommodating and clamping the side ends of the spring terminals.

[0006] This application uses a lever structure formed by cross clamping arms and a pivot to convert pinching force into clamping force, thereby reducing the effort required for insertion and removal. The receiving groove at the end of the clamping section can securely wrap around and clamp the side end of the spring terminal, avoiding damage to the spring terminal and the corresponding socket. Moreover, the overall structure is compact and slender, which can be used for precise operation in the narrow space inside the RF power supply, improving the efficiency and safety of installation and maintenance.

[0007] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, the inner wall of the receiving groove is covered with a soft layer; this solution increases the clamping friction, which can prevent the spring terminal from slipping out and avoid direct contact between hard metal and the surface of the spring terminal, thereby preventing scratches, indentations or even deformation on the terminal surface and ensuring the performance of the spring terminal.

[0008] Preferably, the handle section is an outwardly protruding arc shape, and when the ends of the two handle sections are in contact with each other, the two clamping sections are in a closed state that clamps the spring terminal. This solution makes gripping and applying force more comfortable and forms a physical limit, which plays a role in preventing excessive clamping and effectively avoids damage to the spring terminal due to excessive clamping force, thereby ensuring the consistency and reliability of clamping.

[0009] Preferably, the inner wall of the handle segment has a first thickened portion that protrudes inward, and the outer surface of the first thickened portion is flush with the outer wall of the other handle segment. This solution enhances the bending strength of the handle segment, ensures efficient transmission of leverage force, avoids misalignment between the two handle segments, improves grip comfort, ensures uniform force distribution, and enhances overall structural stability and user experience.

[0010] Preferably, the clamping block has an arc-shaped transition at both corners along the thickness direction of the clamp arm; this solution eliminates sharp edges and corners, effectively preventing damage to components and cables due to scratches or collisions, and improving operational safety.

[0011] Preferably, the outer wall of the clamping section is provided with a thinning groove, and the inner wall is formed with a second thickened part that protrudes inward. The outer surface of the second thickened part is flush with the bottom surface of the thinning groove on the other handle section. By adopting this solution, the thickness of the clamping section is effectively reduced, making it more flexible to operate in a narrow space. It also improves the structural strength of the clamping section. Furthermore, by using a flush fit, it avoids misalignment during clamping and maintains the stability and reliability of the clamping.

[0012] Through the above technical solution, this utility model achieves the following beneficial effects: 1. This application uses a lever structure formed by cross clamping arms and a pivot to convert pinching force into clamping force, thereby reducing the effort required for insertion and removal. The receiving groove at the end of the clamping section can securely wrap around and clamp the side end of the spring terminal, avoiding damage to the spring terminal and the corresponding socket. Moreover, the overall structure is compact and slender, which can be precisely operated in the narrow space inside the RF power supply, improving the efficiency and safety of installation and maintenance. 2. By covering the inner wall of the receiving groove with a soft layer, this application increases the clamping friction, which can prevent the spring terminal from slipping out and avoid direct contact between hard metal and the surface of the spring terminal, thereby preventing scratches, indentations or even deformation on the terminal surface and ensuring the performance of the spring terminal.

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0016] The terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features.

[0017] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0019] Example: like Figure 1 and Figure 2 As shown in the figure, this application discloses a spring terminal clamping tool for inserting and removing spring terminals in a confined space. It is safe, labor-saving and efficient, and can effectively protect the terminals and sockets from damage during operation. The specific structure includes two clamping arms 1 arranged in a cross configuration.

[0020] The clamp arm 1 includes a handle section 11, a transition section 12, and a clamping section 13. The handle section 11 is where the user applies force. It can generate a large clamping force in the clamping section 13 by using a long lever arm and lever principle, which saves effort. The transition section 12 is an intermediate component. Its cross structure ensures the synchronicity and stability of the action. The clamping section 13 is the working end. It is relatively thin and long, and can penetrate into the narrow space inside the RF power supply to reach positions that are difficult for human hands to reach.

[0021] The transition section 12 of the two clamp arms 1 are attached to each other and rotated through the pivot 2, so that the two clamp arms 1 can rotate around the pivot 2 as the fulcrum, thus forming a lever fulcrum.

[0022] The two clamping sections 13 have opposing clamping blocks 131 at their ends, and the opposing sides of the clamping blocks 131 are provided with receiving grooves 1311 for accommodating and clamping the side ends of the spring terminals.

[0023] It should be noted that, due to the presence of the clamping block 131, the two clamping sections 13 remain V-shaped in the closed state, thus creating a triangular gap between them. This gap provides space for the wire connection area at the rear of the spring terminal, preventing damage to the rear of the spring terminal and the wire during the insertion and removal process, and also preventing it from interfering with the insertion and removal process.

[0024] It should be noted that by wrapping the side end of the spring terminal with the inner wall of the receiving groove 1311, the clamping force can be evenly applied to the solid side end of the spring terminal, rather than to other weak or critical parts. This avoids stress concentration caused by point-to-line contact and can prevent indentation or deformation.

[0025] It should be noted that by using the two receiving slots 1311 to hold the two ends, the left and right sliding of the spring terminals during clamping can be effectively limited, thereby ensuring the stability of the insertion and removal operation.

[0026] This utility model forms a lever structure through the cross clamp arm 1 and the pivot 2, which can convert the pinching force into the clamping force, thereby saving effort in the insertion and removal process. The receiving groove 1311 at the end of the clamping section 13 can firmly wrap and clamp the side end of the spring terminal, avoiding damage to the spring terminal and the corresponding socket. Moreover, the overall structure is compact and slender, which can perform precise operation in the narrow space inside the RF power supply, improving the efficiency and safety of installation and maintenance.

[0027] In some embodiments, such as Figure 2 As shown, the inner wall of the receiving groove 1311 is covered with a soft layer 14, which is rubber or other soft contact material.

[0028] The above design increases the clamping friction, which prevents the spring terminal from slipping out and avoids direct contact between hard metal and the surface of the spring terminal, thereby preventing scratches, indentations or even deformation on the terminal surface and ensuring the performance of the spring terminal.

[0029] In some embodiments, such as Figure 1 As shown, the handle section 11 is an arc shape that bulges outward, and when the ends of the two handle sections 11 are in contact with each other, the two clamping sections 13 are in a closed state that clamps the spring terminal.

[0030] The above design makes gripping and applying force more comfortable and forms a physical limit, which prevents excessive clamping and effectively avoids damage to the spring terminals due to excessive clamping force, thereby ensuring the consistency and reliability of clamping.

[0031] In some embodiments, such as Figure 1 As shown, the inner wall of the handle section 11 has a first thickened portion 111 that protrudes inward, and the outer surface of the first thickened portion 111 is flush with the outer wall of the other handle section 11.

[0032] The above design enhances the bending strength of the handle section 11, ensures efficient transmission of leverage force, and prevents misalignment between the two handle sections 11, thereby improving grip comfort, ensuring uniform force distribution, and enhancing overall structural stability and user experience.

[0033] In some embodiments, such as Figure 1 As shown, the clamping block 131 has arc-shaped transitions 1312 at both corners along the thickness direction of the clamp arm 1.

[0034] The above design eliminates sharp edges and corners, effectively preventing damage to components and cables caused by scratches or collisions, and improving operational safety.

[0035] In some embodiments, such as Figure 1 As shown, the outer side wall of the clamping section 13 is provided with a thinning groove 132, and the inner side wall is formed with a second thickened part 133 that protrudes inward. The outer surface of the second thickened part 133 is flush with the bottom surface of the thinning groove 132 on the other handle section 11.

[0036] Through the above design, the thickness of the clamping section 13 is effectively reduced by the thinning groove 132 on the outside, making it more flexible to operate in a narrow space. The structural strength of the clamping section 13 is improved by the second thickening part 133 on the inside. And by flush fitting, misalignment is avoided during clamping, maintaining the stability and reliability of clamping.
