Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a board-end-to-board-end connector structure. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets. They generally refer to electrical connectors. They are devices that connect two active devices and transmit current or signals. The male and female ends can transmit information or current after contact, and are also called connectors.

[0003] However, the existing connectors are more complicated in structure. When the terminals need to be fixed to the board end, they need to be bridged and fixed. Of course, there are also settings where the terminals are directly bent 90 degrees. However, in actual repeated plugging and unplugging tests, because the terminals are in direct contact with the PCB board (and the contact area is small), the force fulcrum is located at the board end when repeatedly plugged and unplugged. Therefore, when there is a certain amount of wear and tear during plugging and unplugging, the board end may wear or loosen, affecting stable use. Utility Model Content

[0004] The main purpose of the utility model is to propose a board-to-board connector structure, aiming to improve the existing terminal structure, thereby increasing the contact area with the board body, reducing the wear of the board body, and further improving the stability of the connector.

[0005] To achieve the above object, the utility model provides a board-to-board connector structure, comprising:

[0006] A male connector, the male connector comprising a male plastic shell and a PIN needle inserted into the male plastic shell, the front end of the PIN needle protruding from the male plastic shell, the rear end of the PIN needle being provided with a first bending portion, the first bending portion extending backwards to form a first welding foot that is flush with or lower than the lower wall of the male plastic shell;

[0007] A female connector, the female connector comprising a female rubber shell, a female groove arranged in the female rubber shell and a female terminal arranged in the female groove, the rear end of the female terminal being provided with a second bending portion, the second bending portion extending backwards to have a second welding foot which is flush with or lower than the lower wall of the female rubber shell.

[0008] In the actual setting, the first bending portion and the second bending portion are respectively arranged between the PIN pin and the first welding foot and the female terminal and the second welding foot, thereby improving the structural rigidity of the terminal, thereby improving the bonding degree between the plastic shell and the terminal, and at the same time, the arrangement of the first bending portion and the second bending portion avoids the problem of directly inserting the first welding foot and the second welding foot into the board body, so that the first welding foot and the second welding foot are arranged horizontally with the board body, thereby increasing the contact area between the welding foot and the board body, thereby improving the installation stability of the connector.

The rear end of the female terminal 22 is provided with a second bending portion 23, and the second bending portion 23 extends backward to have a second welding foot 24 that is flush with or lower than the lower wall of the female rubber shell 20.
