[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1-4 As shown;

[0025] The SMC 90-degree docking male connector includes a main housing 1, a terminal 2 is installed in the main housing 1, and the terminal 2 includes an upper terminal 21 and a lower terminal 22, which are arranged side by side. The terminal 2 is fixed to the surface of the PCB board by SMT horizontal welding, and the female connector also adopts this fixing method, so that the male and female connectors are in a horizontal docking state when connected, which effectively improves the space required for the connector, is conducive to the miniaturization of the terminal equipment, and keeps 1.27PITCH between adjacent terminals, further reducing the size of the connector, which is conducive to the wiring of the terminal product PCB board; and there is no need to pre-select and break the PCB board, saving production costs;

[0026] Furthermore, the upper terminal 21 and the lower terminal 22 both include a fixing portion 23 and a contact portion 24. The fixing portion 23 corresponding to the upper terminal 21 and the fixing portion 23 corresponding to the lower terminal 22 are arranged side by side in the front and back direction. Since the conventional fixing portion is an up-and-down structure or a left-and-right staggered structure, which occupies a large area of ​​the PCB board, the side-by-side arrangement can reduce the area of ​​the PCB board, thereby further improving the space required for the connector.

[0027] Furthermore, the fixing portion 23 and the contact portion 24 are at 90 degrees, which facilitates the welding and fixing of the terminal 2 and reduces the area of ​​the PCB board used;

[0028] Furthermore, a soldering foot 25 is provided at the bottom of the fixing portion 23, and the soldering foot 25 is used to solder and fix the terminal 2 to the surface of the PCB board, so that the connector is in a horizontal state to be plugged in, and the soldering foot 25 and the fixing portion 23 are kept vertical. In this way, when soldering the soldering foot 25, the soldering area occupied by the PCB board is reduced, further reducing the size of the connector, and the soldering foot 25 is thinned, further reducing the soldering area occupied by the PCB board.

[0029] like Figure 1-2 As shown;

[0030] A T-shaped frame opening 4 is provided in the main housing 1, and the T-shaped frame opening 4 is convenient for connecting with the female end connector. Through holes 5 are evenly provided in the upper and lower sides of the main housing 1 corresponding to the T-shaped frame opening 4 to the other side. The terminal 2 is installed on the main housing 1 through the through holes 5. The contact of the terminal 2 does not extend into the T-shaped frame opening 4 through the through holes 5, which is convenient for horizontal docking with the female end connector. In addition, the corresponding number of terminals can be installed according to the actual situation, which is highly practical.

[0031] A fixing piece 3 is provided on each side of the main housing 1. The fixing piece 3 is fixed to the PCB board by welding, so that the entire connector is more firm and the stability of the connector is improved.

[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
