Please refer to Figures 1 to 4 as shown, which shows a preferred embodiment, showing a connector including a housing 1, further including a calibration post 2, a positioning and fixing post 3, a terminal pin 4, and an elastic member 5. One end of the housing 1 is provided with a plurality of terminal pins 4, and each terminal pin 4 is bent at 90°. One end of the terminal pin 4 extends into the housing 1, and the other end of the terminal pin 4 extends out of the housing 1 and extends to one side of the housing 1. One side of the housing 1 is provided with a calibration post 2 and a positioning and fixing post 3. The positioning and fixing post 3 includes a positioning portion 301, a connecting portion 302, a fixing portion 303, and a fixing convex 304. One end of the positioning portion 301 is connected to the housing 1, the other end of the positioning portion 301 is connected to one end of the connecting portion 302, the other end of the connecting portion 302 is connected to one end of the fixing portion 303, a fixing convex 304 is provided on the side of the fixing portion 303 away from the positioning portion 301, and a U-shaped groove is formed between the fixing portion 303 and the positioning portion 301, and an elastic member 5 is arranged in the U-shaped groove. In this embodiment, please refer to Figure 4As shown in the figure, there are two positioning and fixing columns 3 in total, and the two positioning and fixing columns 3 are arranged opposite to each other. The calibration column 2 is arranged between the two positioning and fixing columns 3. The provided positioning and fixing columns 3 are used to cooperate with the positioning holes on the substrate, the provided calibration column 2 is used to cooperate with the calibration holes on the substrate, and the terminal pin 4 is used to cooperate with the welding holes on the substrate. Connect the positioning part 301 to the housing 1, connect the connecting part 302 to the positioning part 301, connect the fixing part 303 to the connecting part 302, and arrange an elastic member 5 between the fixing part 303 and the positioning part 301, so that the fixing part 303 has sufficient elasticity to avoid loosening after being clamped with the substrate. Through the arrangement of the positioning and fixing columns 3 and the calibration column 2, the terminal pin 4 can be smoothly inserted into the welding hole, avoiding bending or deformation of the terminal pin 4.

[0025] Furthermore, as a preferred embodiment, the elastic member 5 is a spring, and both ends of the spring are connected to the fixing part 303 and the positioning part 301. In this embodiment, the elastic member 5 is preferably a spring. By applying a thrust force to the fixing part 303 through the spring, the clamping between the fixing part 303 and the substrate is more stable, avoiding loosening. In other embodiments, the elastic member 5 can be an elastic rubber column, and both ends of the elastic rubber column are connected to the fixing part 303 and the positioning part 301.

[0026] Furthermore, as a preferred embodiment, a first chamfer 305 is provided on the outer edge of the surface of the connecting part 302 away from the positioning part 301. Through the arrangement of the first chamfer 305, it is convenient for the positioning and fixing column 3 to be smoothly inserted into the positioning hole.

[0027] Furthermore, as a preferred embodiment, one end of the calibration column 2 is connected to the housing 1, and a second chamfer 201 is provided on the outer edge of the surface of the other end of the calibration column 2. Through the arrangement of the second chamfer 201, it is convenient for the calibration column 2 to smoothly enter the calibration hole.

[0028] Furthermore, as a preferred embodiment, it further includes a guiding piece 202, and a plurality of guiding pieces 202 are provided on the outer edge of the calibration column 2. Among them, a plurality of guiding grooves are opened on the inner wall of the calibration hole, and the guiding piece 202 can enter the guiding groove, which can prevent the calibration column 2 from rotating in the calibration hole.

[0029] Furthermore, as a preferred embodiment, the length of the calibration column 2 is greater than the length of the positioning and fixing column 3, so that it is convenient for the calibration column 2 to enter the calibration hole first to correct the position of the connector first, and it is convenient for the positioning and fixing column 3 to enter the positioning hole.

[0030] In use, first align the calibration column 2 with the calibration hole, and slowly insert the other end of the calibration column 2 into the calibration hole, so that the positioning and fixing column 3 at this time can be directly opposite to the positioning hole, and the other end of the terminal pin 4 can be directly opposite to the welding hole. Then slowly push the connector. The inner wall of the positioning hole will squeeze the fixing convex 304, and the fixing convex 304 will push the fixing part 303 to move closer to the positioning part 301. At this time, the fixing part 303 will squeeze the elastic member 5. After overcoming the elastic force of the elastic member 5, the fixing convex 304 will completely enter the positioning hole. At the same time, the other end of the terminal pin 4 will slowly enter the welding hole, which can avoid the phenomenon of bending at the other end of the terminal pin 4. And the fixing convex 304 will be stuck in the positioning hole under the action of the elastic member 5 and the fixing part 303, so as to realize the clamping connection between the connector and the substrate. Through the setting of the guiding piece 202 on the calibration column 2, the rotation of the connector can be avoided. And through the mutual cooperation of the fixing part 303 and the elastic member 5, the fixing convex 304 can be tightly stuck in the positioning hole to avoid loosening.

[0031] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention accordingly. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and drawings of the present invention should be included in the protection scope of the present invention.
