Description

Technical Field

[0001] This application relates to the field of electrical connection technology, and in particular to a connection terminal. Background Technology

[0002] As a key component for achieving electrical connections and signal transmission, the performance of connector terminals directly affects the stability and reliability of the entire system. With the continuous development of electronic technology and the increasing demands for equipment integration and miniaturization, higher standards are being placed on the structural design, ease of installation, and connection stability of connector terminals. Currently, connector terminals are widely used in communication equipment, automotive electronics, consumer electronics, and many other fields, ensuring the effective transmission of electrical signals or power through reliable connections with the wiring.

[0003] Currently, most existing connection terminals use a single structure or simple mechanical contact method to fix the cable, which is difficult to meet the requirements for a stable connection of the cable under complex working conditions. When the equipment is running in harsh environments such as vibration and high temperature, the cable is prone to loosening due to external force, resulting in poor contact or even signal interruption. At the same time, the single fixing method has poor adaptability when dealing with cables of different specifications and materials. Therefore, a new type of connection terminal is proposed. Utility Model Content

[0004] The purpose of this application is to provide a connection terminal that has the advantages of multiple fixation of wires of different specifications and materials, effectively meeting the connection needs under complex working conditions, ensuring the stability of electrical connection and signal transmission, and solving the problems raised in the background art.

[0005] The connection terminal provided in this application adopts the following technical solution: it includes a stop portion and a connecting portion arranged sequentially along the axial direction. The stop portion includes a first clamping portion and two second clamping portions inside. The two second clamping portions are respectively located on both sides of the first clamping portion. The first clamping portion includes a first arc-shaped placement seat. Two first clamping pieces are fixedly connected to the outer side of the first arc-shaped placement seat. A first pressure block is fixedly connected to the side of the two first clamping pieces that are close to each other. Two second clamping pieces are fixedly connected to the outer side of the first arc-shaped placement seat. A second pressure block is fixedly connected to the side of the two second clamping pieces that are close to each other. A second elastic piece is fixedly connected to the outer side of the first arc-shaped placement seat. The second clamping portion includes a second arc-shaped placement seat. Two third clamping pieces are fixedly connected to the outer side of the second arc-shaped placement seat. Multiple equidistantly arranged first barbs are fixedly connected to the side of the two third clamping pieces that are close to each other. Multiple equidistantly arranged second barbs are fixedly connected to the outer side of the second arc-shaped placement seat.

[0006] By adopting the above technical solution, a three-level clamping system is formed by the cooperation of the first clamping part and the second clamping part inside the stop part. The first arc-shaped placement seat achieves the center positioning and fixation of the wire body through the first pressure block and the second pressure block. The second arc-shaped placement seats on both sides provide lateral locking through the first barb and the second barb. Then, the second elastic sheet applies pressure to the wire body through its own elastic deformation to further prevent the wire body from loosening. This effectively solves the problem of the single fixing method of traditional terminals, improves the stability of the connection under complex working conditions, avoids poor contact caused by external force, and adapts to the fixing requirements of wires of different specifications.

[0007] Preferably, a second tapered connecting block is fixedly connected to both sides of the first arc-shaped placement base, and the side of the second tapered connecting block away from the first arc-shaped placement base is fixedly connected to the outer side of the second arc-shaped placement base.

[0008] By adopting the above technical solution, the second tapered connecting block flexibly connects the first arc-shaped placement seat and the second arc-shaped placement seat. Its tapered structure not only makes the internal structure of the stop part transition more smoothly and reduces stress concentration, but also optimizes the layout in a limited space, improves the overall structural strength of the stop part, and ensures the stable performance of multiple fixing functions.

[0009] Preferably, the first barb and the second barb are arranged in a right-angled triangle shape.

[0010] By adopting the above technical solution, the right-angled triangular configuration of the first and second barbs forms an asymmetrical locking surface, which can be effectively embedded into the surface of the line, increase friction, and prevent the line from slipping when pulled by external force. Especially in a vibration environment, it can significantly improve the fixing effect on the line and avoid problems such as poor contact caused by the line loosening.

[0011] Preferably, each of the second barbs extends laterally, and each of the first barbs extends longitudinally, with the first and second barbs arranged in a cross-shaped spatial arrangement.

[0012] By adopting the above technical solution, the second barb extending laterally is orthogonal to the first barb extending longitudinally, forming a grid-like locking structure in three-dimensional space. This constrains the wire from multiple dimensions, forming a three-dimensional fixing structure. It can effectively limit both the longitudinal tension and lateral displacement of the wire, greatly improving the stability of the connection terminal in fixing the wire, and also enhancing the adaptability to wires of different specifications and materials.

[0013] Preferably, the second elastic piece is located between the first clamping piece and the second clamping piece, and the second elastic piece is provided with a raised shape.

[0014] By adopting the above technical solution, the second elastic sheet with a raised shape is located between the first clamping sheet and the second clamping sheet to form a floating clamping cavity. The raised part can closely fit the surface of the thread and use the pressure generated by the elastic deformation to fix the thread for a second time. It can also adapt to threads of different thicknesses, further improving the fixing effect and adaptability.

[0015] Preferably, the connecting part includes a connecting seat, and a first tapered connecting block is fixedly connected to the outer side of the connecting seat. One side of the first tapered connecting block is fixedly connected to the outer side of the second arc-shaped placement seat. The interior of the connecting seat is hollow, and two symmetrical first elastic pieces are fixedly connected to the outer side of the connecting seat. The two first elastic pieces are convex in shape.

[0016] By adopting the above technical solution, the first tapered connecting block and the connecting seat are connected to the second arc-shaped placement seat, which optimizes the overall structural strength. The two first elastic pieces with convex shapes can make elastic contact with the external structure during the connection process, which increases the tightness and stability of the connection and prevents the connecting terminals from loosening during use.

[0017] Preferably, two symmetrical clamping plates are fixedly connected to the outer side of the connecting seat, and an elastic gasket is fixedly connected to the outer side of the connecting seat.

[0018] By adopting the above technical solution, the clamping plate and elastic gasket on the outside of the connector work together. The clamping plate can apply pressure to the wire or connecting parts, while the elastic gasket buffers the external force through its own elasticity. The combination of the two can not only further fix the wire, but also reduce the loosening of the connection caused by external force impact, and improve the reliability of the connecting terminal in complex environments.

[0019] Preferably, the ends of the two clamping plates furthest from the outer side of the connecting seat are arranged in an arc shape.

[0020] By adopting the above technical solution, the arc shape at the end of the clamping plate forms a guide slope, which guides the mating terminal to be inserted accurately. At the same time, the arc surface can better fit the surface of the wire, provide more uniform pressure, and enhance the fixing effect.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This type of connector terminal forms a three-level clamping system by setting a first clamping part inside the stop part and second clamping parts on both sides. The first and second pressure blocks on the first arc-shaped placement seat achieve precise positioning of the wire center. The first and second barbs on the second arc-shaped placement seat form a cross-shaped locking network. The second barb in the lateral direction inhibits radial displacement, and the first barb in the longitudinal direction prevents axial loosening, which completely solves the problem of wire loosening under vibration conditions. The flexible transition design of the second tapered connecting block disperses stress concentration and prevents the clamping part from breaking. The raised second elastic sheet compensates for wire diameter tolerance and temperature deformation through deformation to maintain a constant clamping force. The pressure plate and elastic pad in the connecting part work together. The pressure plate applies pressure to the wire or connecting parts to further ensure the overall stable connection of the connector terminal. It comprehensively overcomes the defects of the existing technology, such as single fixing method, poor vibration resistance and low adaptability, and significantly improves the stability and reliability of the connection under complex working conditions.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A connection terminal, please refer to Figure 1, Figure 3 and Figure 4 The device includes a stop portion 1 and a connecting portion 2 arranged sequentially along the axial direction. The stop portion 1 includes a first clamping portion 3 and two second clamping portions 4, which are located on both sides of the first clamping portion 3. The first clamping portion 3 includes a first arc-shaped placement seat 301. Two first clamping pieces 302 are fixedly connected to the outer side of the first arc-shaped placement seat 301. A first pressure block 305 is fixedly connected to the side of the two first clamping pieces 302 that are close to each other. Two second clamping pieces 304 are fixedly connected to the outer side of the first arc-shaped placement seat 301. A second pressure block 306 is fixedly connected to the side of the two second clamping pieces 304 that are close to each other. The first arc-shaped placement seat 301, through the first pressure block 305 and the second pressure block 306, achieves the center positioning and fixation of the thread. A second elastic piece 303 is fixedly connected to the outer side of the first arc-shaped placement seat 301. The second elastic piece 303 applies pressure to the thread through its own elastic deformation to further prevent the thread from loosening. Both sides of the first arc-shaped placement seat 301... A second tapered connecting block 307 is fixedly connected. The side of the second tapered connecting block 307 away from the first arc-shaped placement seat 301 is fixedly connected to the outside of the second arc-shaped placement seat 401. The second tapered connecting block 307 flexibly connects the first arc-shaped placement seat 301 and the second arc-shaped placement seat 401. Its tapered structure not only makes the internal structure transition of the stop part 1 smoother and reduces stress concentration, but also optimizes the layout in a limited space, improves the overall structural strength of the stop part 1, and ensures the stable performance of multiple fixing functions. The second elastic piece 303 is located between the first clamping piece 302 and the second clamping piece 304. The second elastic piece 303 is convex in shape. The convex second elastic piece 303 is located between the first clamping piece 302 and the second clamping piece 304 to form a floating clamping cavity. The convex part can closely fit the surface of the wire and use the pressure generated by the elastic deformation to fix the wire a second time. It can also adapt to wires of different thicknesses, further improving the fixing effect and adaptability.

[0032] Please refer to Figure 1 , Figure 3 and Figure 5The second clamping part 4 includes a second arc-shaped placement seat 401. Two third clamping pieces 402 are fixedly connected to the outer side of the second arc-shaped placement seat 401. Multiple equidistantly arranged first barbs 403 are fixedly connected to the side of each of the two third clamping pieces 402 that are close to each other. Multiple equidistantly arranged second barbs 404 are fixedly connected to the outer side of the second arc-shaped placement seat 401. The first barbs 403 and second barbs 404 are arranged in a right-angled triangle configuration. This right-angled triangular configuration forms an asymmetrical locking surface, which can effectively embed into the surface of the thread, increase friction, and prevent the thread from slipping when subjected to external force, especially under vibration conditions. To improve the fixing effect on the cable and avoid problems such as poor contact caused by cable loosening, each second barb 404 extends laterally, and each first barb 403 extends longitudinally. The first barbs 403 and second barbs 404 are arranged in a cross shape in space. The laterally extending second barbs 404 and the longitudinally extending first barbs 403 are spatially orthogonal, forming a grid-like locking structure in three-dimensional space. This constrains the cable from multiple dimensions and forms a three-dimensional fixing structure. It can effectively limit both longitudinal tension and lateral displacement of the cable, greatly improving the stability of the connection terminal fixing the cable and enhancing the adaptability to cables of different specifications and materials.

[0033] Example 2: A connection terminal, please refer to Figure 1 and Figure 2The connecting part 2 includes a connecting seat 201. A first tapered connecting block 202 is fixedly connected to the outer side of the connecting seat 201. One side of the first tapered connecting block 202 is fixedly connected to the outer side of the second arc-shaped placement seat 401. The interior of the connecting seat 201 is hollow. Two symmetrical first elastic pieces 203 are fixedly connected to the outer side of the connecting seat 201. The two first elastic pieces 203 are convex in shape. The first tapered connecting block 202 is connected to the connecting seat 201 and the second arc-shaped placement seat 401 to optimize the overall structural strength. The two convex first elastic pieces 203 can make elastic contact with the external structure during the connection process, increasing the tightness and stability of the connection and preventing the connecting terminals from loosening during use. The outer side of the connecting seat 201 is fixedly connected to two... A symmetrical clamping plate 204 is fixedly connected to the outer side of the connector 201, and an elastic pad 205 is fixedly connected to it. The clamping plate 204 and the elastic pad 205 on the outer side of the connector 201 work together. The clamping plate 204 can apply pressure to the wire or the two connecting parts, while the elastic pad 205 buffers the external force through its own elasticity. The two not only further fix the wire, but also reduce the loosening of the connection caused by external impact, and improve the reliability of the connecting terminal in complex environments. The ends of the two clamping plates 204 away from the outer side of the connector 201 are set in an arc shape. The arc shape at the end of the clamping plate 204 forms a guide slope to guide the mating terminal to be accurately inserted. At the same time, the arc surface can better fit the surface of the wire, provide more uniform pressure, and enhance the fixing effect.

[0034] It should be noted that the second tapered connecting block 307 absorbs lateral vibration energy, and the second elastic sheet 303 releases longitudinal stress through deformation. When the temperature changes, the elastic element automatically compensates for the difference in the material expansion coefficient to maintain a constant clamping force. The first barb 403 and the second barb 404 of the right triangle ensure the unidirectional self-locking characteristics in the vibration environment, realizing the core functions of smooth insertion and removal and firm locking.

[0035] The implementation principle of this application embodiment is as follows: When in use, the thread is placed in the stop part 1. The first arc-shaped placement seat 301 and the second arc-shaped placement seat 401 provide the initial placement position for the thread. The first clamping piece 302, the first pressure block 305, the second clamping piece 304 and the second pressure block 306 clamp and fix the thread from different directions. Then, the second elastic piece 303, with its own protruding shape and elastic deformation, tightly fits the surface of the thread and applies pressure to achieve secondary fixation. At the same time, the first barb 403 and the second barb 404 on the outside of the second arc-shaped placement seat 401 of the second clamping part 4 are embedded in the surface of the thread in a cross-shaped three-dimensional structure, restricting the movement of the thread from multiple dimensions. The cross-shaped barbs form a spatial interlocking network, completely restricting the displacement of the thread. Subsequently, the connecting part 2 performs the terminal docking function. When the mating terminal is inserted into the connecting seat 201, the arc-shaped end of the clamping plate 204 guides the mating terminal to slide into the hollow cavity. The protrusion of the first elastic plate 203 generates elastic deformation to provide insertion resistance feedback, ensuring reliable physical connection. At the same time, the clamping plate 204 and the elastic pad 205 work together. The clamping plate 204 applies pressure to the wire or the two connecting parts, and the elastic pad 205 buffers the external force, further ensuring the overall stable connection of the connecting terminal. Through the coordinated operation of the stop part 1 and the connecting part 2, multiple fixation of the wire is achieved, effectively meeting the connection requirements under complex working conditions and ensuring the stability of electrical connection and signal transmission.
