Description

Technical Field

[0001] This utility model relates to the field of hardware terminals, and in particular to a hardware terminal for connectors. Background Technology

[0002] In electronic device connection systems, connector hardware terminals are core components for achieving circuit conduction, widely used in various electronic terminal products such as communication equipment, automotive electronics, and consumer electronics. Their main function is to establish a stable current or signal transmission channel through mating with adapter terminals, ensuring efficient communication between various modules of the electronic device. The structural design of the hardware terminals directly affects the reliability, conductivity, and lifespan of the connection, thus occupying a crucial position in the overall performance of electronic devices.

[0003] However, existing connector hardware terminals still have certain shortcomings in practical applications. Some traditional terminals have unreasonable mating structures, where the mating cylinder and the inner wall of the mating adhesive rely primarily on simple friction for fixation, lacking a dedicated elastic clamping structure. This frictional mating method has limited clamping force and is prone to loosening under the influence of environmental factors such as long-term insertion / removal, vibration, or temperature changes. With increased usage time, the friction surfaces are prone to wear, leading to increased mating clearances, which in turn causes poor terminal contact, resulting in signal transmission interruptions, unstable current, and in severe cases, even affecting the normal operation of the entire electronic device. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a solution that can effectively solve the technical problem that the connection is prone to loosening as wear increases.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A hardware terminal for a connector includes a fixed base plate, a plug-in cylinder, and a soldering part. The fixed base plate, plug-in cylinder, and soldering part are integrally formed by stamping. The plug-in cylinder and the soldering part are located at opposite ends of the fixed base plate. The side wall of the soldering part is bent to form a pressure plate. The pressure plate is parallel to the axis of the plug-in cylinder. A clamping spring is also provided. The clamping spring includes a clamping part and a connecting part. The connecting part is fixedly connected to the fixed base plate. The clamping part extends into the inner plug-in cylinder. The clamping part is composed of two or more elastic arms. The two or more elastic arms are evenly distributed around the axis of the plug-in cylinder. The elastic arms are arc-shaped and bent toward the axis of the plug-in cylinder.

[0007] Furthermore, the end of the insertion cylinder away from the fixed base plate is provided with a guide opening and a constriction. The guide opening is located at the end of the constriction away from the fixed base plate, and the outer wall of the guide opening and the outer wall of the constriction combine to form a recessed positioning part.

[0008] Furthermore, the guide opening expands outward in a trumpet shape, and the constriction narrows in an arc shape toward the axis of the insertion cylinder.

[0009] Furthermore, a bending portion is provided between the fixed base plate and the welding portion.

[0010] Furthermore, a limiting plate is bent at one end of the fixed base plate. The limiting plate is L-shaped and bends toward the center of the insertion cylinder and passes through the extension line of the axis of the insertion cylinder.

[0011] Furthermore, the inner wall of the insertion cylinder is provided with a guide groove, and the end of the clamping part away from the connecting part is bent into an abutment part. When the clamping part of the connecting part is deformed, the abutment part moves along the guide groove.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By setting a clamping part composed of two or more elastic arms, with the elastic arms evenly distributed around the axis of the insertion cylinder, the traditional method of fixing terminals that relies solely on frictional engagement between the insertion cylinder and the inner wall of the insertion adhesive is changed. This allows for multi-point elastic clamping when the adapter terminal is inserted. This multi-elastic arm distribution structure effectively solves the problems of insufficient clamping force and easy loosening caused by simple frictional engagement, significantly improving the connection stability and clamping force between the terminal, the insertion adhesive, and the adapter component. Secondly, the arc-shaped structure of the elastic arms, bent towards the axis of the insertion cylinder, allows the elastic arms to generate continuous elastic pressure when in contact with the inner wall of the insertion adhesive and the adapter terminal. This ensures both tight clamping and good elastic adjustment capability, which can offset wear gaps during long-term use. It can maintain a stable clamping effect even under environments with vibration and temperature changes, reducing contact problems caused by loosening of the insertion. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] The following is combined Figures 1-3 A detailed description is provided of a metal terminal for a connector according to this utility model:

[0019] A connector hardware terminal includes a fixed base plate 1, a plug-in cylinder 2, and a welding part 3. The fixed base plate 1, plug-in cylinder 2, and welding part 3 are integrally formed by stamping. The plug-in cylinder 2 and welding part 3 are located at opposite ends of the fixed base plate 1. The side wall of the welding part 3 is bent to form a pressure plate 4, which is parallel to the axis of the plug-in cylinder 2. A clamping spring 5 is also provided. The clamping spring 5 includes a clamping part 501 and a connecting part 502. The connecting part 502 is fixedly connected to the fixed base plate 1. The clamping part 501 extends into the inner plug-in cylinder 2 and is composed of two elastic arms 511. The two elastic arms 511 are symmetrically distributed around the axis of the plug-in cylinder 2. The elastic arms 511 are arc-shaped and bent towards the axis of the plug-in cylinder 2. The inner wall of the plug-in cylinder 2 is provided with two or more symmetrically distributed guide grooves 201 along the axial direction. The guide grooves 201 are elongated groove structures. The free end of the clamping part 501 away from the connecting part 502 is bent towards the inner wall of the insertion cylinder 2 to form an arc-shaped abutment part 503. The outer wall of the abutment part 503 fits against the inner wall of the guide groove 201. When the clamping part 501 is squeezed by the adapter terminal and undergoes elastic deformation, the abutment part 503 can slide back and forth along the length of the guide groove 201. The cooperation between the guide groove 201 and the abutment part 503 can guide and limit the elastic deformation of the clamping part 501, preventing the elastic arm 511 from shifting or twisting laterally when under force, ensuring the uniform deformation of multiple elastic arms 511, and ensuring a uniform distribution of clamping force. At the same time, the sliding of the abutment part 503 along the groove can disperse the force points of the clamping part 501, reduce local stress concentration, extend the fatigue life of the elastic arm 511, and ensure that a stable clamping force can still be maintained after long-term use.

[0020] By setting a clamping part 501 composed of two or more elastic arms 511, with the elastic arms 511 evenly distributed around the axis of the insertion cylinder 2, the traditional fixing method of the terminal relying solely on frictional engagement between the insertion cylinder 2 and the inner wall of the insertion adhesive is changed, enabling multi-point elastic clamping when the adapter terminal is inserted. This multi-elastic arm 511 distribution structure effectively solves the problems of insufficient clamping force and easy loosening caused by simple frictional engagement, significantly improving the connection stability and clamping force between the terminal, the insertion adhesive, and the adapter component. Secondly, the arc-shaped structure of the elastic arms 511, bent towards the axis of the insertion cylinder 2, allows the elastic arms 511 to generate continuous elastic pressure when in contact with the inner wall of the insertion adhesive and the adapter terminal. This ensures both tight clamping and good elastic adjustment capability, which can offset wear gaps during long-term use and maintain a stable clamping effect under environments such as vibration and temperature changes, reducing contact problems caused by loosening of the insertion.

[0021] The end of the plug-in cylinder 2 away from the fixed base plate 1 is provided with a guide opening 6 and a constriction 7 along the axial direction. The guide opening 6 and the constriction 7 are integrally formed. The guide opening 6 is located on the side of the constriction 7 away from the fixed base plate 1. The outer wall of the guide opening 6 is an outwardly inclined slope, and the outer wall of the constriction 7 is an inwardly concave arc surface. The connection between the two forms a ring-shaped concave positioning part. After the insulating shell is extruded, the inner wall engages with the positioning part, making the hardware terminal more stable and preventing loosening.

[0022] The guide opening 6 expands outward in a trumpet shape. By increasing the entrance area, the trumpet-shaped guide opening 6 can significantly reduce the alignment accuracy requirements when inserting the adapter terminal, making the insertion and removal operation more convenient and smooth. At the same time, the smooth transition surface can reduce the impact force during the insertion and removal process and extend the service life of the terminal. The constriction 7 is arc-shaped and shrinks towards the axis of the insertion cylinder 2. After the adapter terminal is inserted, the arc-shaped constriction 7 can form a radial clamping force, which, together with the elastic clamping of the clamping spring 5, forms a double fixation, enhancing the compatibility with adapter terminals of different diameters and improving the tightness of the connection.

[0023] The fixed base plate 1 has a 90° bend 8 at one end near the welding part 3. The bend 8 offsets the welding part 3 away from the axis of the insertion cylinder 2, making the central axis of the welding part 3 parallel to the central axis of the insertion cylinder 2 with a preset offset. The welding part 3 and the fixed base plate 1 achieve a vertical transition through the bend 8. The design of the bend 8 realizes the misalignment of the axes of the welding part 3 and the insertion cylinder 2, which can avoid the cable twisting problem caused by spatial interference after wire welding, and facilitate the neat arrangement of wires in a limited installation space. The parallel axis design ensures that the force direction of the welding part 3 is consistent with the insertion direction, reduces the torque generated on the insertion part when the wire is pulled, and reduces the risk of loosening of the insertion due to wire stress.

[0024] One end of the fixed base plate 1 is bent to provide a limiting plate 9. The limiting plate 9 is "L" shaped. The limiting plate 9 bends toward the center of the insertion cylinder 2 and passes through the extension line of the axis of the insertion cylinder 2. The design of the limiting plate 9 passing through the extension line of the axis can limit the radial and axial displacement of the terminal. In the vibration environment, it can effectively resist the impact of external force, prevent the terminal from falling out of the insulating shell, and improve the overall structural strength of the connector.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
