Technical Field
[0001] This utility model relates to the field of wire-to-board connector technology, specifically a wire-to-board connector with stable contact. Background Technology
[0002] A wire-to-board connector is a connector used to connect wires or cables to a circuit board. They typically achieve electrical connection through pins and sockets. The pins are fixed to the circuit board, and the sockets are fixed to the wires. When a pin is inserted into the socket, the metal leads make tight contact with the metal slot, thus establishing an electrical connection. This connection method is simple, reliable, and easy to install and maintain. To improve the efficiency of wire connections, a wire-to-board connector is needed. However, existing wire-to-board connectors still have the following shortcomings:
[0003] When using existing wire-to-board connectors, most wire-to-board connectors do not easily and stably confine the mounting terminals inside the pin socket, causing the mounting terminals to easily detach from the pin socket, thus affecting the normal electrical connection and resulting in a decrease in the practicality and efficiency of the wire-to-board connectors.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a wire-to-board connector with stable contact. Utility Model Content
[0005] The purpose of this invention is to provide a wire-to-board connector with stable contact to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable contact wire-to-board connector, comprising a pin holder body and a limiting ball. The pin holder body has an internal mounting groove, and a conductive pin is added to the middle of the internal part of the pin holder body. Limiting grooves are also provided at both ends of the internal part of the pin holder body. Receiving grooves are provided on both sides of the internal part of the pin holder body. A spring damping rod is installed inside the receiving groove, and a limiting ball is provided at the front end of the spring damping rod. A snap-fit groove is provided on the outer side of the internal part of the pin holder body. A mounting terminal is connected inside the mounting groove, and a mating groove is provided at the middle of the internal part of the mounting terminal. Limiting sliders are added to both ends of the external part of the mounting terminal. Limiting grooves are also provided on both sides of the internal part of the mounting terminal. Auxiliary springs are added to both sides of the external part of the mounting terminal, and hooks are added to the front ends of the auxiliary springs. A fixing seat is added to the middle of the rear end of the mounting terminal, and a connecting wire is connected to the rear end of the fixing seat.
[0007] Furthermore, the internal dimensions of the mounting groove are adapted to the external dimensions of the mounting terminal, and the mounting terminal is slidably connected to the pin holder body through the mounting groove.
[0008] Furthermore, the number of conductive needles is set to four, and the four conductive needles are equidistantly distributed in the middle of the needle holder body.
[0009] Furthermore, the internal dimensions of the limiting groove are adapted to the external dimensions of the limiting slider, and the limiting slider is embeddedly connected to the needle seat body through the limiting groove.
[0010] Furthermore, there are two spring damping rods, and the two spring damping rods are symmetrically arranged on both sides of the front central axis of the needle holder body.
[0011] Furthermore, the internal dimensions of the snap-fit groove are adapted to the external dimensions of the snap hook, and the snap hook is connected to the needle holder body through the snap-fit groove.
[0012] Furthermore, the internal dimensions of the limiting groove are adapted to the external dimensions of the limiting ball, and the limiting ball is elastically connected to the limiting groove through a spring damping rod.
[0013] Furthermore, the outer side of the auxiliary spring piece and the outer side of the hook are horizontally distributed, and the hook is fixedly connected to the auxiliary spring piece by bolts.
[0014] This invention provides a wire-to-board connector with stable contact, which has the following advantages:
[0015] 1. This utility model, through the setting of the limiting ball, enables the limiting ball to elastically connect with the receiving groove through the spring damping rod when using a wire-to-board connector with stable contact. The limiting groove and the limiting slider are used to install the mounting terminal into the needle holder body. The internal dimensions of the limiting grooves opened on both sides of the mounting terminal are adapted to the external dimensions of the limiting ball. Thus, after the mounting terminal is installed into the needle holder body, the mounting terminal is limited by the limiting ball and the limiting groove, thereby increasing the stability of the mounting terminal after installation and improving the overall efficiency of the wire-to-board connector.
[0016] 2. This utility model, through the setting of the hook, enables the auxiliary spring to be fixedly installed on both sides of the outside of the mounting terminal by fastening bolts when using a wire-to-board connector with stable contact. The hook is also fixed on the outside of the auxiliary spring by fastening bolts. At the same time, the snap-fit groove and the hook further increase the stability of the mounting terminal after sliding installation.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figures 1 to 3As shown, a stable contact wire-to-board connector includes a pin holder body 1 and a limiting ball 7. The pin holder body 1 has an internal mounting groove 2, and a conductive pin 3 is added to the middle of the internal part of the pin holder body 1. Limiting grooves 4 are formed at both ends of the internal part of the pin holder body 1. Receiving grooves 5 are formed on both sides of the internal part of the pin holder body 1. A spring damping rod 6 is installed inside the receiving groove 5, and a limiting ball 7 is provided at the front end of the spring damping rod 6. The internal dimensions of the mounting groove 2 are adapted to the external dimensions of the mounting terminal 9, and the mounting terminal 9 is slidably connected to the pin holder body 1 through the mounting groove 2. Four conductive pins 3 are provided, and the four conductive pins 3 are equidistantly distributed at the middle of the internal part of the pin holder body 1. The internal dimensions of the limiting groove 4 are adapted to the external dimensions of the limiting slider 11, and the limiting slider 11 is embeddedly connected to the pin holder body 1 through the limiting groove 4. Two spring damping rods 6 are provided, and the two spring damping rods 6 are symmetrically arranged about the central axis of the front of the pin holder body 1. Inside the body 1, conductive pins 3 are fixedly installed in the middle of the needle holder body 1 by fastening bolts. Spring damping rods 6 are also fixedly installed in the receiving grooves 5 on both sides of the needle holder body 1. Limiting balls 7 are fixedly installed at the front end of the spring damping rods 6, and the spring damping rods 6 allow the limiting balls 7 to elastically connect with the receiving grooves 5. The internal dimensions of the limiting grooves 4 at both ends of the needle holder body 1 are adapted to the external dimensions of the limiting sliders 11 added to both ends of the mounting terminal 9. Thus, the mounting terminal 9 is installed into the needle holder body 1 through the limiting grooves 4 and the limiting sliders 11. Furthermore, the internal dimensions of the limiting grooves 12 on both sides of the mounting terminal 9 are adapted to the external dimensions of the limiting balls 7. Therefore, after the mounting terminal 9 is installed into the needle holder body 1, the limiting balls 7 and the limiting grooves 12 limit the mounting terminal 9, thereby increasing the stability of the mounting terminal 9 after installation and improving the overall efficiency of the wire-to-board connector.
[0023] like Figure 1 and Figure 2As shown, the needle holder body 1 has a snap-fit groove 8 on its inner outer side. A mounting terminal 9 is connected inside the mounting groove 2, and a mating groove 10 is formed in the middle of the mounting terminal 9. Limiting sliders 11 are added to both ends of the mounting terminal 9. Limiting grooves 12 are formed on both sides of the mounting terminal 9. Auxiliary spring pieces 13 are added to both sides of the mounting terminal 9, and hooks 14 are added to the front ends of the auxiliary spring pieces 13. A fixing seat 15 is added to the middle of the rear end of the mounting terminal 9, and a connecting wire 16 is connected to the rear end of the fixing seat 15. The internal dimensions of the snap-fit groove 8 are adapted to the external dimensions of the hooks 14, and the hooks 14 are connected to the needle holder body 1 through the snap-fit groove 8. The internal dimensions of the limiting groove 12 are adapted to the external dimensions of the limiting ball 7, and the limiting ball 7 is elastically connected to the limiting groove 12 through a spring damping rod 6. The auxiliary spring pieces... The outer sides of 13 and 14 are horizontally distributed, and the hooks 14 are fixedly connected to the auxiliary spring 13 by bolts. The auxiliary spring 13 is fixedly installed on both sides of the outside of the mounting terminal 9 by fastening bolts, and the hooks 14 are fixedly installed on the outside of the auxiliary spring 13 in conjunction with the fastening bolts. At the same time, the external dimensions of the hooks 14 are adapted to the internal dimensions of the snap-fit groove 8 opened on the inner side of the pin seat body 1. Thus, the snap-fit groove 8 and the hooks 14 further increase the stability of the mounting terminal 9 after sliding installation. The auxiliary spring 13 can easily disassemble the mounting terminal 9, thereby improving the convenience of the disassembly process. The fixing seat 15 is fixedly installed on the rear end of the mounting terminal 9. The fixing seat 15 is used to fix and limit the connecting wire 16, and further improve the overall practicality and efficiency of the wire-to-board connector.
[0024] In summary, this stable contact wire-to-board connector, during use, firstly, the internal dimensions of the mounting groove 2 inside the pin holder body 1 are adapted to the external dimensions of the mounting terminal 9 at the front end of the fixing seat 15. The conductive pin 3 is then fixedly installed in the middle of the pin holder body 1 using fastening bolts. Simultaneously, the spring damping rod 6 is fixedly installed in the receiving grooves 5 on both sides of the pin holder body 1 using the fastening bolts. The spring damping rod 6 allows the limiting ball 7 to elastically connect with the receiving groove 5. The mounting terminal 9 is then installed into the pin holder body 1 using the limiting slide groove 4 and the limiting slider 11. Furthermore, the internal dimensions of the limiting grooves 12 on both sides of the mounting terminal 9 are adapted to the external dimensions of the limiting ball 7, thus allowing the mounting terminal 9 to be installed into the pin holder body. After the internal positioning, the mounting terminal 9 is limited by the limiting ball 7 and the limiting groove 12, thereby increasing the stability of the mounting terminal 9 after installation. Then, the auxiliary spring piece 13 is fixedly installed on both sides of the outside of the mounting terminal 9 by the fastening bolt, and the hook 14 is fixedly installed on the outside of the auxiliary spring piece 13 by the fastening bolt. At the same time, the snap-fit groove 8 and the hook 14 are used to further increase the stability of the mounting terminal 9 after sliding installation. The auxiliary spring piece 13 can easily disassemble the mounting terminal 9, thereby improving the convenience of the disassembly process. The fixing seat 15 is fixedly installed on the rear end of the mounting terminal 9. The fixing seat 15 is used to fix and limit the connecting wire 16, and further improve the overall practicality and efficiency of the wire-to-board connector.
