[0023] As Figures 1 - 3 shown, Figure 1 is a three-dimensional structural schematic diagram of a connection terminal; Figure 2 is a three-dimensional structural schematic diagram of a connection body 1; Figure 3 is a three-dimensional structural schematic diagram of a housing 2. The connection terminal includes a connection body 1 and a housing 2. The housing 2 is sleeved on the connection body 1. When in use, both ends of the connection body 1 are respectively connected to the pin and the copper sleeve of the PCB board.

[0024] In specific applications, the connection body 1 includes a connecting pipe 11, a plurality of connecting pieces 12 and a plurality of elastic insertion pieces 13. The plurality of connecting pieces 12 are located at one end of the connecting pipe 11, and the plurality of elastic insertion pieces 13 are located at the other end of the connecting pipe 11. Specifically, one end of each of the plurality of connecting pieces 12 is connected to one end of the connecting pipe 11, and the other end of the connecting piece 12 extends along the length direction. One end of the elastic insertion piece 13 is connected to the outer surface of the other end of the connecting pipe 11, and the other end of the elastic insertion piece 13 extends away from the outer surface of the connecting pipe 11. At the same time, the elastic insertion piece 13 can swing reciprocally relative to the outer surface of the connecting pipe 11. In this embodiment, the connecting pipe 11 is cylindrical. Along the length direction of the connecting pipe 11, the connecting pipe 11 has a first receiving hole 112 and a second receiving hole 113, and the plurality of connecting pieces 12 are distributed around the first receiving hole 112. Further, the connecting pipe 11 also has a plurality of first receiving openings 111, and the first receiving openings 111 communicate with the second receiving hole 113. The plurality of elastic insertion pieces 13 respectively correspond to the plurality of first receiving openings 111, that is, one elastic insertion piece 13 is provided in one first receiving opening 111. Through the arrangement of the first receiving openings 111, it is convenient for the elastic insertion piece 13 to move into the second receiving hole 113 through the first receiving opening 111 when assembling and being stressed, avoiding damage to the elastic insertion piece 13 and reducing the resistance during assembly.

[0025] Preferably, the elastic insertion piece 13 has a protrusion 131, which is provided at the end of the elastic insertion piece 13 away from the connecting pipe 11, and the protrusion 131 opens in a direction away from the connecting pipe 11. Through the arrangement of the protrusion 131, the contact effect between the elastic insertion piece 13 and the copper sleeve of the PCB board can be improved. In addition, the connection body 1 further includes a support block 14, and the support block 14 is located at the connection between the elastic insertion piece 13 and the connecting pipe 11, that is, a part of the support block 14 connects one end of the elastic insertion piece 13, and the other part of the support block 14 is connected to the surface of the connecting pipe 11. Through the arrangement of the support block 14, a support force can be provided for the elastic insertion piece 13. For example, when the elastic insertion piece 13 is assembled with the copper sleeve of the PCB board, due to the force, one end of the elastic insertion piece 13 moves towards the first receiving hole 112, and the other end of the elastic insertion piece 13 remains connected to the connecting pipe 11 and the support block 14. At this time, the support block 14 will provide a certain reverse support for the elastic insertion piece 13, improving the service life of the elastic insertion piece 13. In this embodiment, the number of support blocks 14 is the same as the number of elastic insertion pieces 13, that is, there is one elastic insertion piece 13 in each first receiving opening 111, and each elastic insertion piece 13 is connected with a support block 14.

[0026] The housing 2 includes a sleeve 21 and a plurality of first fixing pieces 22. The sleeve 21 is sleeved on the outer surfaces of the connecting piece 12 and the connecting pipe 11. The plurality of first fixing pieces 22 are arranged at intervals at one end of the sleeve 21, and the plurality of first fixing pieces 22 are bent towards the inside of the sleeve 21 and abut against the connecting piece 12, that is, the connecting piece 12 is fixed by the first fixing pieces 22 and the inner wall surface of the sleeve 21 together. Further, the housing 2 further includes a plurality of supporting pieces 23. The plurality of supporting pieces 23 are annularly arranged on the outer surface of the sleeve 21, and the plurality of supporting pieces 23 respectively abut against the plurality of connecting pieces 12. Through the arrangement of the supporting pieces 23, a positive force is provided for the connecting piece 12, and support is also provided for the connecting piece 12. In this embodiment, the number of the supporting pieces 23 is the same as the number of the connecting pieces 12, that is, one supporting piece 23 abuts against one connecting piece 12. The housing 2 further includes a positioning piece 24. One end of the positioning piece 24 is connected to the outer surface of the sleeve 21, and the other end of the positioning piece 24 extends away from the sleeve 21. Through the arrangement of the positioning piece 24, it is convenient to perform positioning and assembly with other components in the follow-up. Specifically, the number of the positioning pieces 24 is two, and the two positioning pieces 24 are respectively oppositely arranged on both sides of the sleeve 21.

[0027] Furthermore, the housing 2 further includes a second fixing piece 25. The connecting pipe 11 has a second receiving opening 114, and the second receiving opening 114 communicates with the first receiving hole 112. The second fixing piece 25 is clamped in the second receiving opening 114 to enhance the stability of the connection between the sleeve 21 and the connecting pipe 11. In this embodiment, the number of the second fixing pieces 25 is two, and the two second fixing pieces 25 are oppositely arranged. During use, the two second fixing pieces 25 respectively extend into the first receiving hole and are bent, so that the second fixing piece 25 abuts against the inner wall surface of the first receiving hole 112, thereby realizing the fixed connection between the sleeve 21 and the connecting pipe 11.

[0028] Specifically, both the connecting piece 12 and the elastic insertion piece 13 are made of high-conductivity and high-yield-strength materials, such as spring materials.

[0029] In summary, through the arrangement of the plurality of elastic insertion pieces 13 that can swing relative to the connecting pipe 11, when one end of the connecting pipe 11 provided with the elastic insertion pieces 13 is inserted into the copper sleeve on the PCB board, one ends of the plurality of elastic insertion pieces 13 are stressed and move towards the direction close to the connecting pipe 11 and remain in contact with the copper sleeve. Using the elastic insertion pieces 13 to replace the traditional drum spring structure can not only reduce the insertion and extraction force, but also the movement of the elastic insertion pieces 13 is convenient for the installation with the copper sleeve. In addition, the plurality of elastic insertion pieces 13 increase the contact points with the copper sleeve, thereby reducing the processing precision requirements for the copper sleeve on the PCB board.
