Description

Technical Field

[0001] This utility model relates to the field of terminal conductive sheet technology, and in particular to a high-performance connector terminal conductive sheet. Background Technology

[0002] A terminal connection assembly is a device used to achieve a detachable electrical connection between conductors and electrical components or wires in a circuit. Its definition can be summarized as follows: it consists of a flexible terminal spring and a matching conductor. The elastic clamping force of the spring ensures tight contact between the two, forming a conductive path. In this assembly, the mounting plate of the terminal spring is used to fix the assembly to a base or circuit board. The elastic clamping plate generates elastic deformation through a preset angle and arc-shaped connection part, forming a stable contact with the inserted conductor. The corresponding groove and conductor are designed to assist in positioning and reserve buffer space to ensure connection reliability.

[0003] The limitations of existing terminal connection assemblies are mainly reflected in insufficient structural rationality and connection stability. However, the claims of this application can effectively solve these problems through targeted design: In existing assemblies, some terminal springs do not clearly distinguish between installation and conductive functions, and the overall structural rigidity distribution is unreasonable, resulting in insufficient elastic compression deformation capacity and difficulty in forming stable contact with the conductor; if the connection part adopts a right angle design, it is easy to generate cracks due to stress concentration, reducing service life; at the same time, the positioning structure between the spring and the conductor is missing, lacking groove and gap fit, making it easy to misalign during installation. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a high-performance connector terminal conductive sheet to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a high-performance connector terminal conductive sheet, including a terminal bullet and a conductor. The terminal bullet includes an integrally formed mounting plate and an elastic pressure plate. The elastic pressure plate is located between the mounting plate and the conductor. Two grooves are formed on the side of the elastic pressure plate near the conductor. The mounting plate and the elastic pressure plate form a preset angle. The connection between the mounting plate and the elastic pressure plate is arc-shaped. The conductor is a flat insert structure. The conductor is arranged along the extension direction of the elastic pressure plate. The conductor and the elastic pressure plate are matched opposite to each other. The grooves are correspondingly arranged with the conductor. A gap is left between the conductor and the elastic pressure plate to form an electrical connection.

[0007] Preferably, the end bullet is made of SUS301 material and the surface of the end bullet is nickel-plated.

[0008] Preferably, the conductor is made of H65 material with a hardness of HV135, as described in any of the above schemes.

[0009] Preferably, the edge burr size of the end bullet piece is ≤0.03mm, the planar portion of the mounting piece is flat, the curved surface of the elastic pressure piece is smooth, the whole piece is free from twisting and deformation, and the connection between the mounting piece and the elastic pressure piece is free from cracks.

[0010] Preferably, in any of the above embodiments, the end of the elastic pressure plate away from the arc-shaped connection portion is curved upward to form a guide portion, the angle between the guide portion and the mounting plate is 62°, and the angle between the elastic pressure plate 102 and the mounting plate 101 is 38°.

[0011] Preferably, in any of the above embodiments, the two grooves are spaced apart along the length of the elastic pressure plate, and the cross-sectional shape of the grooves is V-shaped or U-shaped.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. During installation, the assembly is secured using the mounting plate of the end spring clip. The conductor is inserted along the guide section of the elastic pressure plate. Because the elastic pressure plate and the mounting plate form a 38° angle, and they transition through a rounded connection, the elastic pressure plate can naturally deform and conform to the conductor. The V-shaped or U-shaped grooves on the elastic pressure plate correspond to the conductor, and the pre-reserved gap between them ensures precise positioning and no interference when the conductor is inserted. The 62° angle between the guide section and the mounting plate further guides the conductor smoothly into the contact area. This design clearly distinguishes the functions of the mounting plate and the elastic pressure plate, giving the elastic pressure plate reasonable deformation capabilities. The rounded connection avoids stress concentration, solving the problem of cracking that easily occurs in traditional right-angle connections. The fit between the grooves and the gap eliminates the risk of installation misalignment. The edge burrs of the end spring clip are ≤0.03mm, and the flat surface and smooth curved surface ensure uniform contact between the elastic pressure plate and the conductor, improving connection stability and assembly lifespan.

[0014] 2. The end spring clips are made of SUS301 material with nickel plating, ensuring good elasticity and corrosion resistance during long-term use. The conductor is made of H65 material with a hardness of HV135, matching the material properties of the elastic clips to ensure efficient conductivity during contact. The curved surface of the elastic clips is smooth and free from twisting deformation, fitting tightly to the flat structure of the conductor and reducing contact resistance. This design, through targeted material selection of SUS301 nickel-plated end spring clips and H65 conductors, solves the problems of poor conductivity and easy corrosion caused by material incompatibility in traditional components. Strict processing precision requirements, such as the absence of cracks and burrs, ensure effective contact between the elastic clips and the conductor. At the same time, the angle design of the guide section improves adaptability in different scenarios, enabling the component to stably conduct current or signals in various electrical connection scenarios.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0020] like Figures 1 to 3 As shown, a high-performance connector terminal conductive sheet includes a terminal bullet 1 and a conductor 2. The terminal bullet 1 includes an integrally formed mounting plate 101 and an elastic pressure plate 102. The elastic pressure plate 102 is located between the mounting plate 101 and the conductor 2. Two grooves 3 are formed on the side of the elastic pressure plate 102 near the conductor 2. The mounting plate 101 and the elastic pressure plate 102 form a preset angle. The connection part between the mounting plate 101 and the elastic pressure plate 102 is arc-shaped. The conductor 2 is a flat insert structure. The conductor 2 is arranged along the extension direction of the elastic pressure plate 102. The conductor 2 and the elastic pressure plate 102 are matched and engaged. The grooves 3 are correspondingly arranged with the conductor 2. A gap is left between the conductor 2 and the elastic pressure plate 102 to form an electrical connection.

[0021] As an optional technical solution of this utility model, the end bullet piece 1 is made of SUS301 material and the surface of the end bullet piece 1 is nickel-plated. The end bullet piece 1 is made of SUS301 material and the surface is nickel-plated. SUS301 has excellent elasticity and fatigue resistance, ensuring that the elastic pressure plate 102 can maintain a stable clamping force after repeated deformation. The nickel plating treatment can improve the corrosion resistance and conductivity of the end bullet piece 1, avoid poor contact due to oxidation and rust during long-term use, and extend the service life of the component.

[0022] As an optional technical solution of this utility model, the conductor 2 is made of H65 material with a hardness of HV135. The conductor 2 is made of H65 material with a state of T0.0.6 and a hardness of HV135. H65 has good conductivity and processing performance, which is compatible with the material characteristics of the end bullet piece 1 and ensures the current conduction efficiency when the two are in contact. The specific state and hardness parameters ensure that the conductor 2 has sufficient structural strength and is not easily deformed when inserted into the elastic pressure piece 102, thus maintaining a stable contact state.

[0023] As an optional technical solution of this utility model, the edge burr size of the end bullet piece 1 is ≤0.03mm, the flat part of the mounting piece 101 is flat, the curved surface of the elastic pressure piece 102 is smooth, the whole is without twisting or deformation, and there are no cracks at the connection between the mounting piece 101 and the elastic pressure piece 102. The edge burr size of the end bullet piece 1 is ≤0.03mm, the flat surface of the mounting piece 101, the smooth curved surface of the elastic pressure piece 102 without twisting or deformation, and the connection without cracks can avoid burrs scratching the conductor 2 or the operator. The flat surface ensures that the elastic pressure piece 102 and the conductor 2 are in uniform contact, and the crack-free connection prevents structural failure caused by stress concentration, thereby improving the safety and reliability of the component.

[0024] As an optional technical solution of this utility model, the end of the elastic pressure plate 102 away from the arc-shaped connection part is curved upward to form a guide part 4. The angle between the guide part 4 and the mounting plate 101 is 62° and the angle between the elastic pressure plate 102 and the mounting plate 101 is 38°. The guide part 4 of the elastic pressure plate 102 and the mounting plate 101 form an angle of 62° and 38° respectively. The angle design of the guide part 4 provides clear guidance for the insertion of the conductor 2, reducing insertion resistance and misalignment probability. The 38° angle gives the elastic pressure plate 102 a reasonable elastic deformation space, ensuring that an appropriate clamping force is generated when in contact with the conductor 2, balancing contact stability and insertion convenience.

[0025] As an optional technical solution of this utility model, two grooves 3 are distributed at intervals along the length direction of the elastic pressure plate 102. The cross-sectional shape of the grooves 3 is V-shaped or U-shaped. The two grooves 3 of the elastic pressure plate 102 are distributed at intervals along the length direction and have a V-shaped or U-shaped cross-section. The grooves 3 are correspondingly set with the conductor 2 to assist in positioning and prevent the conductor 2 from shifting laterally during contact. The V-shaped or U-shaped cross-sectional shape can adapt to the edge contour of the conductor 2. With the gap between the two, it can not only ensure positioning accuracy, but also reserve space for the deformation of the elastic pressure plate 102 and prevent damage to the components caused by excessive compression.

[0027] 1): Using the mounting plate of the end bullet piece to fix the assembly, the conductor is inserted along the guide part of the elastic pressure plate.

[0028] 2): The V-shaped or U-shaped grooves on the elastic pressure plate correspond to the conductor, and the gap between them ensures accurate positioning and no interference when the conductor is inserted; the 62° angle design between the guide part and the mounting plate further guides the conductor smoothly into the contact area.

[0029] 3) The conductor is made of H65 material with a hardness of HV135, which matches the material properties of the elastic pressure plate to ensure conductivity during contact; the bending surface of the elastic pressure plate is smooth and free from twisting deformation, and fits tightly with the flat plate structure of the conductor to reduce contact resistance.

[0030] In summary, this high-performance connector terminal conductive piece utilizes the mounting plate of the terminal bullet to fix the assembly during installation. The conductor is inserted along the guide portion of the elastic pressure plate. Because the elastic pressure plate and the mounting plate form a 38° angle, and they transition through an arc-shaped connection, the elastic pressure plate can naturally deform and conform to the conductor. The V-shaped or U-shaped grooves on the elastic pressure plate correspond to the conductor, and the pre-reserved gap between them ensures accurate positioning and no interference when the conductor is inserted. The 62° angle design between the guide portion and the mounting plate further guides the conductor smoothly into the contact area. This design clearly distinguishes the functions of the mounting plate and the elastic pressure plate, giving the elastic pressure plate reasonable deformation capability. The arc-shaped connection avoids stress concentration, solving the problem of cracking that easily occurs in traditional right-angle connections. The fit between the groove and the gap eliminates the risk of installation misalignment. The edge burrs of the terminal bullet ≤0.03mm and the flat surface and smooth curved surface ensure uniform contact between the elastic pressure plate and the conductor, improving connection stability and component lifespan. The end spring clips are made of SUS301 material with nickel plating, ensuring good elasticity and corrosion resistance during long-term use.
