[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] The existing electrical connector is only bent to form a contact point, and only the end with the contact point can contact the patch. Therefore, when installing, it is necessary to distinguish the two ends of the electrical connector and select the correct direction for installation. Once the installation direction of the two ends of the electrical connector is reversed, it is necessary to reinstall, which may easily cause the electrical connector to loosen. In addition, the connector has only one contact point that can be welded with the patch, and the welding firmness is low.

[0020] For the above technical issues, refer to Figure 1 The present embodiment provides a charging contact connector, including a plastic base 1, wherein at least two mutually parallel fixing grooves 12 are provided inside a main body 11 of the plastic base 1, and a metal guide pin 2 is provided in the fixing groove 12 in a one-to-one correspondence. The metal guide pin 2 is used for conducting electricity, and the two ends of the metal guide pin 2 have the same structure.

[0021] Since the structures of the two ends of the metal guide pin 2 are the same, both ends can be used as conductive contacts. During installation, the two ends of the metal guide pin 2 do not need to be distinguished, and the charging contact connector can be installed on the circuit board in any direction. There is no need to adjust the charging contact connector due to the direction of the metal guide pin 2, and the installation of the charging contact connector can be completed at one time, which is simple to operate and assemble.

[0022] Furthermore, the charging contact connector can be installed on the circuit board in one step, thus avoiding the loosening of the fit between the charging contact connector and the docking component that may be caused by repeated disassembly, thereby reducing the possibility of loosening.

[0023] The ends of both ends of the metal guide pin 2 form a contact surface 4 respectively, and the two contact surfaces 4 are connected to a spring pin respectively for charging. The two ends of the metal guide pin 2 can be SMTed at the same time, and the charging contact connector can be fixed from both ends to improve the firmness of the installation.

[0024] Reference Figure 2 The metal guide needle 2 includes a cylindrical conductor fixing portion 22, and the conductor fixing portion 22 is located in the fixing groove 12 and is wrapped by the main body 11 from the circumferential side, so that the metal guide needle 2 is firmly fixed in the plastic base 1.

[0025] A circular conductor end portion 21 is formed at both ends of the conductor fixing portion 22, and the conductor end portion 21 contacts the upper portion of the main body 11.

[0026] The contact surface 4 is formed at the end of the conductor end 21 .

[0027] Reference Figure 3 A positioning column 3 is fixed on the main body 11, and two positioning columns 3 are arranged between two adjacent metal guide needles 2, and the connecting line between the two positioning columns 3 is inclined relative to the axial direction of the metal guide needle 2.

[0028] A mounting hole is provided on the circuit board. When the charging contact connector is mounted on the circuit board, the positioning column 3 penetrates into the mounting hole on the circuit board to position the charging contact connector on the circuit board.

[0029] Working principle:

[0030] Since the structures of both ends of the metal guide pin 2 are the same, when the charging contact connector is installed on the circuit board, the metal guide pin 2 can be installed in any direction without distinguishing the direction, and there is no need to repeatedly split the metal guide pin 2 due to the contact direction. The installation of the charging contact connector can be achieved in one step, which reduces the possibility of loosening of the charging contact connector and improves the firmness of the installation.

[0031] The ends of both ends of the metal guide pin 2 form a contact surface 4 respectively, and the two contact surfaces 4 are connected to a spring pin respectively for charging. The two ends of the metal guide pin 2 can be simultaneously surface mounted (SMT), and the charging contact connector can be fixed from both ends to improve the firmness of the installation.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
