[0019] The utility model discloses an expansion part structure schematic diagram.

[0020] As Figures 1-5 The utility model provides a kind of electrically conductive terminal for electric connector, including insert part 1, one end of insert part 1 is fixedly connected with expansion part 2, and expansion part 2 inside is hollow structure.Specific use, expansion part 2 position is inserted into the fixed perforation of printed circuit board (not shown in the drawing) and realizes the effect of fixed connection.

[0021] Expansion part 2 includes ellipsoid segment 3, end tail 4 and end head 5, end tail 4, ellipsoid segment 3 and end head 5 are sequentially distributed along the direction away from insert part 1, end tail 4, ellipsoid segment 3 and end head 5 adopt integrated forming process.

[0022] When expansion part 2 is inserted into the fixed perforation of printed circuit board, first end head 5 passes through fixed perforation, then ellipsoid segment 3 enters and is clamped on fixed perforation, so as to realize the fixed effect of electrically conductive terminal on printed circuit board.

[0023] The top of ellipsoid segment 3 is provided with first through slot 6, the top of end tail 4 is provided with second through slot 7, the top of end head 5 is provided with third through slot 8, first through slot 6 is communicated between second through slot 7 and third through slot 8, and second through slot 7, first through slot 6 and third through slot 8 form through groove.

[0024] Through groove is arranged, and expansion part 2 inside is hollow structure, so that expansion part 2 has better elastic deformation capacity, so that electrically conductive terminal is not easy to be brittle in plugging operation.

[0025] The inner wall of ellipsoid segment 3 is integrally formed with inner reinforcing rib 11, the inner reinforcing rib 11 is arranged as multiple, and the multiple inner reinforcing ribs 11 are equidistantly distributed, so that ellipsoid segment 3 maintains structural strength and prolongs the service life of electrically conductive terminal by arranging ellipsoid segment 3.

[0026] The end tail 4 is provided with a cutout 12 near one end of the insertion part 1, and the cutout 12 is located on the side of the end tail 4 close to the second through groove 7. The cutout 12 does not affect the deformation of the position of the end tail 4 in the second through groove 7.

[0027] Due to the larger volume of the ellipsoidal segment 3 compared to the end head 5 and other positions, the deformation is more obvious. The first through groove 6 is provided in an elliptical shape to improve the structural strength while ensuring the elastic deformation ability of the ellipsoidal segment 3.

[0028] In order to maintain good elastic properties of the bulging part 2, an elastic block 10 is provided inside the end tail 4. The elastic block 10 can be made of insulating rubber material and has a certain elasticity.

[0029] When the bulging part 2 is inserted into the fixed hole of the printed circuit board, the bulging part 2 is squeezed and shrinks. The bulging part 2 squeezes the elastic block 10, which also shrinks and deforms. The reset elastic force of the elastic block 10 maintains good reset effect of the bulging part 2. Even if the elastic properties of the bulging part 2 decrease due to long-term use, the bulging part 2 can be stably clamped on the fixed hole, improving the stability of the electrical connector and the printed circuit board connection.

In actual use, threaded holes can be provided on the clamping block 9, and screws can be passed through the threaded holes to fix the clamping block 9 on the insertion part 1. The adjustment can be made according to the specific use.

[0031] When the elastic properties of the elastic block 10 decrease due to long-term use, the elastic block 10 can be pulled out from the second through groove 7 by the clamping block 9, and then replaced without replacing the entire conductive terminal, reducing the use cost. During the replacement process, the operator can move the second through groove 7 to make the second through groove 7 larger, which is convenient for replacement and can be adjusted according to the specific use.

Even if the elastic properties of the bulging part 2 decrease due to long-term use, the bulging part 2 can be stably clamped on the fixed hole, improving the stability of the electrical connector and the printed circuit board connection. At the same time, the elastic block 10 is easy to replace, and the entire conductive terminal does not need to be replaced, reducing the use cost.
