[0029] The pogo pin is a spring-type probe formed by the three basic components of a needle shaft, a spring, and a needle tube, which are pre-pressed by riveting with precision instruments. It is mainly used for current and signal transmission, that is, charging and conducting. For some situations that require the use of an extra-small connector, a small pogo pin is required. Due to the small diameter of the needle tube, the needle tube and the needle shaft are easily bent when punching and pressing the needle shaft into the needle tube, affecting the quality of the connector. This is difficult to achieve for some small connectors and ultra-precision components. In addition, solid pins are used in some cases, but solid pins do not have the spring structure of pogo pins, so they cannot be compressed. There is a possibility that the mating end will be damaged during connection. Therefore, an elastic connector is needed that can meet the compression requirements of the solid pin and avoid the bending of the needle tube and needle shaft of the small connector.

[0035] The limiting member 230 is disposed on the needle shaft 200 , and is used to prevent the needle shaft 200 from popping out of the plastic hole 110 .
[0036] In the technical solution of the utility model, the elastic connector includes a plastic seat 100, a needle shaft 200, an elastic member 300 and a stopper 230. At least one plastic hole 110 is set on the plastic seat 100. The plastic hole 110 runs through the plastic seat 100. Each elastic member 300 is correspondingly set in a plastic hole 110, and the elastic member 300 is compressed along the axial direction of the plastic hole 110. Each needle shaft 200 passes through an elastic member 300 and passes through the plastic hole 110. The stopper 230 is set at one end of the needle shaft 200. When the connector is used to connect the electrical When manufacturing a sub-product, an elastic member 300 is provided to provide a compression force to prevent the hard connection from damaging the needle shaft 200. In addition, the plastic hole 110 on the plastic seat 100 replaces the original needle tube structure, and the needle shaft 200 passes through the plastic hole 110 to directly conduct the signal or current, thereby saving structural space, reducing production costs, and avoiding the bending of the needle shaft 200 and the needle tube caused by drilling a hole in the needle tube, which affects the quality of the connector, and facilitates the connection of ultra-precision components. The limit member 230 can prevent the needle shaft 200 from popping out of the plastic hole 110, thereby improving the stability of the connector.
[0037] In detail, the number of plastic holes 110 and needle shafts 200 is consistent, and different numbers of plastic holes 110 and needle shafts 200 are set according to actual needs. In addition, the cross-section of the plastic hole 110 can be circular or rectangular, etc., as long as it can accommodate the elastic member 300 and provide compression space for the elastic member 300, and allow the needle shaft 200 to pass through the plastic hole 110. Of course, in most cases, a plastic hole 110 with a circular cross-section can be selected for ease of processing and improved aesthetics. The elastic member 300 is provided with a through hole for the needle shaft 200 to pass through.
[0038] In an embodiment of the present invention, the needle shaft 200 has a first shaft end 210, the first shaft end 210 is located outside the plastic hole 110, and the limiting member 230 is provided at the first shaft end 210, and the size of the limiting member 230 is larger than the size of one end of the plastic hole 110 close to the first shaft end 210, so as to limit the limiting member 230 outside the plastic hole 110.
[0039] Please refer to Figure 2 The needle shaft 200 has a first shaft end 210 located outside the plastic hole 110, and the limiting member 230 is arranged at the first shaft end 210, and can be specifically arranged at the outer periphery of the first shaft end 210, and the outer edge size of the needle shaft 200 is larger than the diameter of the plastic hole 110. When the needle shaft 200 is connected to the plastic seat 100, the second shaft end 220 and the limiting member 230 are outside one end of the plastic hole 110 and cooperate with the plastic hole 110, and the other end of the needle shaft 200 is at the other end of the plastic hole 110. When the connector is used for connection, the elastic member 300 is compressed, which can prevent the needle shaft 200 from popping out in a direction away from the first shaft end 210 after the elastic member 300 is compressed and restored to its original state, so that the connection between the plastic seat 100 and the needle shaft 200 is stable.
[0040] In the embodiment of the present invention, the needle shaft 200 further has a second shaft end 220 opposite to the first shaft end 210 , and the size of one end of the second shaft end 220 close to the elastic member 300 is greater than or equal to the elastic member 300 to prevent the second shaft end 220 from passing through the elastic member 300 .
[0041] Please refer to Figure 2 The needle shaft 200 also has a second shaft end 220 at the other end of the plastic hole 110. The second shaft end 220 is in direct contact with the elastic member 300, and the diameter of the second shaft end 220 is larger than the through hole diameter of the elastic member 300. The second shaft end 220 can be limited to one side of the plastic hole 110 to prevent the second shaft end 220 from passing through the elastic member 300 and detaching from the plastic seat 100.
[0042] In the embodiment of the present invention, one end of the second shaft end 220 away from the elastic member 300 is located outside the plastic hole 110 .
[0043] Please refer to Figure 2 One end of the second shaft end 220 is close to the elastic member 300 and is in direct contact with the elastic member 300. When the electronic product needs to be connected, the second shaft end 220 moves toward the first shaft end 210 to compress the elastic member 300, and the end of the second shaft end 220 away from the elastic member 300 is outside the plastic hole 110, which is convenient for connecting with the electronic product.
[0044] In the embodiment of the present invention, the dimension of one end of the plastic hole 110 close to the second shaft end 220 is larger than the dimension of one end of the plastic hole 110 close to the first shaft end 210 , and the plastic hole 110 and the second shaft end 220 restrict the elastic member 300 in the plastic hole 110 .
[0045] Please refer to Figure 2 The diameter of one end of the plastic hole 110 close to the second shaft end 220 is greater than or equal to the size of the elastic member 300, which facilitates the elastic member 300 to enter the plastic hole 110, while the diameter of one end of the plastic hole 110 close to the first shaft end 210 is smaller than the size of the elastic member 300, preventing the elastic member 300 from escaping from the plastic hole 110 at this end. The elastic member 300 is limited in the plastic hole 110 through the second shaft end 220 and the plastic hole 110, providing compression force for the needle shaft 200.
[0046] In an embodiment of the present invention, one of the first shaft end 210 and the second shaft end 220 is configured to connect a signal and / or power output terminal, and the other of the first shaft end 210 and the second shaft end 220 is configured to connect a signal and / or power input terminal.
[0047] Specifically, the second shaft end 220 can be used as an input end to connect to the output end of the signal and / or power supply, such as a hand piece, and the first shaft end 210 can be used as an output end to connect to the input end of the signal and / or power supply, such as a welding wire, and the needle shaft 200 is used to guide the current and / or signal from the second shaft end 220 to the first shaft end 210. It can be understood that the first shaft end 210 can also be used as an output end to connect to the input end of the signal and / or power supply, and the second shaft end 220 can be used as an output end to connect to the input end of the signal and / or power supply.
[0048] In the embodiment of the present invention, the plastic seat 100 and the needle shaft 200 are injection molded.
[0049] Specifically, after the needle shaft 200 is inserted into the elastic member 300, the elastic member 300 is inserted from the end with a larger diameter of the plastic hole 110. At this time, since the diameter of the limiting member 230 is larger than the end with a smaller diameter of the plastic hole 110, the needle shaft 200 is riveted toward the first shaft end 210 by an air press, and the needle shaft 200 is riveted into the plastic hole 110. At this time, the limiting member 230 is limited outside the plastic hole 110. Finally, the molten polymer material is quickly injected into the plastic hole 110 at the second shaft end 220 by an injection molding machine at a certain pressure. After cooling and solidification, the needle shaft 200 and the plastic seat 100 are injection molded.
[0050] In the embodiment of the present invention, the elastic member 300 is configured as a spring.
[0051] Please refer to Figure 2 The spring has good elasticity and recovery. It is compressed instantly when two electronic products are connected, and rebounds after stabilization, which can avoid damaging the needle shaft 200. In addition, the spring has a long service life, good durability and fatigue resistance, and reduces maintenance costs and replacement costs.
