A socket is provided at the top of the connector for insertion of gold fingers on an external PCB board. In some vertical-mount connectors, the spacing between adjacent terminals is very small, and the contact portions on all terminals are arranged in a row, resulting in a very close spacing between adjacent contact portions. In actual use, this structure is prone to short circuits, affecting the reliability of the electrical connection. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0024] The structure of the vertical connector in the embodiment of the present utility model is as follows Figures 1 to 5As shown, it includes a socket 1, and terminals 2 and positioning pieces 3 provided on the socket 1; when in use, the vertical connector is fixed to the circuit board by welding, and the electrical connection between the circuit board and the PCB board is realized by contacting the terminals 2 with the gold fingers on the external PCB board, and at the same time, the reliability of the fixed connection between the connector and the circuit board is enhanced by welding the positioning piece 3 with the fixed position on the circuit board; specifically, the upper end of the socket 1 is provided with a PCB board socket 11, and the PCB board socket 11 is for the gold finger end of the PCB board to be inserted, and a terminal insertion hole 12 is provided in the PCB board socket 11, and the lower end of the terminal insertion hole 12 extends to the bottom surface of the socket 1 to form a terminal insertion hole 13, and the terminals 2 are inserted into the terminal insertion hole 12 one by one by the terminal 2 sockets, and each terminal 2 is provided with an upwardly extending power connection spring arm 21, and the power connection spring arm 21 has a contact portion 22 protruding into the PCB board socket 11, and each terminal 2 is provided with a welding Foot 23; the terminal 2 is divided into a terminal 1 24 and a terminal 2 25 which are alternately arranged at intervals in the length direction of the socket 1, and the contact portion 22 on the terminal 1 24 and the contact portion 22 on the terminal 2 25 are at different height positions; by dividing the terminal into a terminal 1 24 and a terminal 2 25 which are alternately arranged at intervals in the length direction of the socket 1, and setting the contact portion on the terminal 1 24 and the contact portion on the terminal 2 25 at different height positions, the spacing between two adjacent contact portions 22 is increased. In this way, when the PCB board is inserted into the PCB board socket, the gold fingers on the PCB board contact with the corresponding contact portions 22 to achieve electrical connection. Since the adjacent contact portions 22 are at different high positions in the up and down directions, the corresponding adjacent contact portions 22 can contact with the gold fingers on the PCB board at different height positions, thereby reducing the short circuit problem easily caused by the adjacent contact portions being too close, and achieving a more reliable electrical connection.

[0025] Further, combined Figure 2 and Figure 3 As shown, in order to increase the spacing between the solder pin 23 of terminal 1 24 and the solder pin 23 of terminal 2 25, the solder pin 23 on terminal 1 24 and the solder pin 23 on terminal 2 25 are arranged to extend from opposite sides of the bottom of the socket 1 respectively, forming a staggered distribution. Because of their staggered distribution, the distance between the solder pins 23 is larger than the original design. Because the spacing between the solder pins 23 is increased, the solder pins 23 are easier to correctly connect with the solder pads at corresponding positions on the circuit board, thereby reducing the risk of poor connection or short circuit caused by position deviation and improving the reliability and stability of the connector.

[0026] like Figure 3As shown, in order to enhance the reliability of the electrical connection between the contact portion 22 and the gold finger on the PCB board, an elastic support portion 26 is provided on the lower portion of the connecting spring arm 21 on the side facing away from the contact portion 22. The elastic support portion 26 is suitable for abutting against the corresponding side wall of the terminal jack 12. The elastic support portion 26 has certain elastic characteristics and can provide effective elastic support for the corresponding position of the connecting spring arm 21, thereby enhancing the contact force between the contact portion 22 and the gold finger to maintain a stable and reliable electrical connection; when the contact portion 22 is subjected to external pressure or vibration, the elastic support portion 26 can play a role of buffering and protection, so that the electrical connection will not be interrupted or loosened due to external factors.

[0027] Continue to read Figure 3 As shown, as a preferred embodiment, the elastic support part 26 is an arc-shaped sheet and its two ends are connected to the connecting elastic arm 21, and a through-hole 27 is formed on the inner side of the elastic support part 26. The outer edge of the elastic support part 26 forms an elastic abutment with the corresponding side wall of the terminal jack 12; during production, the elastic support part 26 is integrally formed with the terminal 2 by punching; the through-hole 27 is a closed-loop structure, and the existence of the through-hole 27 makes the elastic support part 26 elastic. Compared with the elastic support part 26 structure with only one end connected to the connecting elastic arm 21, since both ends of the elastic support part 26 are connected to the connecting elastic arm 21, the elastic support part 26 has a strong anti-deformation ability and is not easily damaged, and can provide more stable and effective elastic support for the connecting elastic arm 21.

[0028] Further, see Figure 3 The terminal 2 has a fixed arm 28 extending upward, and the fixed arm 28 is opposite to the connecting spring arm 21 and is arranged in the same plane. During production, the fixed arm 28 is integrally formed with the terminal 2 by punching; the socket 1 is provided with a fixed slot 14 that is tightly fitted with the fixed arm 28, and the side of the fixed arm 28 is provided with a burr 281, and the burr 281 is preferably set to a triangular hook structure. The burr 281 can enhance the bonding force between the fixed arm 28 and the fixed slot 14, thereby enhancing the reliability of the connection between the terminal 2 and the socket 1.

[0029] In order to adapt to the positioning installation of the positioning piece 3 on the socket 1, positioning piece holes 15 are provided at both ends of the socket 1. The positioning piece holes 15 are arranged in the up and down directions and have an opening at the bottom. The positioning piece 3 is tightly fitted into the positioning piece hole 15 through the opening; the bottom of the positioning piece 3 is provided with positioning feet 34 extending from the opposite sides of the bottom of the socket 1 respectively; during installation, the positioning feet 34 at the bottom of the positioning piece 3 are welded to the corresponding pads on the circuit board to ensure that the positioning piece 3 is reliably connected to the circuit board, thereby ensuring that the vertical connector is firmly installed on the circuit board.

[0030] like Figure 4As shown, in order to further enhance the reliability of the connection between the positioning piece 3 and the socket 1, a second ridge 31 is provided on the side of the positioning piece 3, and the second ridge 31 is tightly fitted with the positioning piece socket 15. It is preferably set to a triangular hook structure. At the same time, a latch tooth 32 is provided on both sides of the upper end of the positioning piece 3, and a latch hole 16 that is engaged with the latch tooth 32 is provided on the side wall of the positioning piece socket 15, and a second through-hole 33 is formed on the positioning piece 3 at a position corresponding to the latch tooth 32; the existence of the second through-hole 33 makes the latch tooth 32 elastic, so that during the insertion process of the positioning piece 3 and the positioning piece socket 15, the latch tooth 32 is elastically deformed to reduce the resistance generated by the latch tooth 32, so that the positioning piece 3 can be smoothly inserted into the positioning piece socket 15; when the positioning piece 3 is inserted into place, the latch tooth 32 is elastically reset and forms a latching fit with the latch hole 16, thereby ensuring a stable connection between the positioning piece 3 and the socket 1. In order to facilitate injection molding, the card hole 16 is set to pass through the socket 1 horizontally and be connected with the positioning piece insertion hole 15; it is preferred to set the second through-hole 33 to be elliptical and to be a closed-loop structure; the long direction of the ellipse (i.e., the long axis direction) is the up and down direction, and the short direction of the ellipse (i.e., the short axis direction) is the force direction when the positioning piece 3 is inserted into the positioning piece insertion hole 15. The closed-loop structure and the elliptical design help to reduce deformation caused by compression and improve the durability and performance of the second through-hole 33.

[0031] Furthermore, in order to adapt to automated production, a protruding edge 17 is provided on the outer edge of the upper end of the socket 1, and the upper surface of the protruding edge 17 is arranged coplanar with the upper surface of the socket 1, so that a plane with a larger purchase area can be formed on the upper end of the socket 1, which is conducive to the adsorption and transfer of the socket 1 during automated production; and the protruding edge 17 is only provided on the upper end of the socket 1, which will not increase excessive material costs.

[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
