Description

Technical Field

[0001] The utility model relates to the field of electronic connectors, and specifically relates to a pin-header and female-header connector. Background Art

[0002] A pin header is a type of connector that is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its function is to act as a bridge between interrupted or isolated circuits within a circuit, taking on the task of current or signal transmission. It is usually used in conjunction with a female header to form a board-to-board connection, or with electronic wire harness terminals to form a board-to-wire connection, and can also be used independently for board-to-board connection.

[0003] However, for most pin-header and female-header connectors on the market today, when used together, the pin header may fall off the female header due to some shaking, causing the contact terminals to deviate from their working positions and resulting in the loss of connection function. Based on this background, the utility model proposes a pin-header and female-header connector assembled by a snap module. This connector sets a connection frame outside the female-header seat and the pin-header seat, and uses an external snap module to snap and lock the connection frame, thereby keeping the female-header seat and the pin-header seat tightly connected and avoiding the situation of connection slippage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pin-header and female-header connector to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pin-header and female-header connector includes a pin-header seat and a female-header seat assembled by a snap module. The outer sides of the female-header seat and the pin-header seat are both provided with connection frames of the same size. A plurality of female-header slots are arranged in an array on the female-header seat, and a metal terminal is provided inside each female-header slot. An anti-fooling mark is provided on the pin-header seat, and a number of pin-header pins corresponding to the female-header slots are provided on the side of the pin-header seat facing the female-header seat. The snap module includes two snap units arranged in a mirror image. Each snap unit includes a back plate, an upper buckle plate and a lower buckle plate integrally connected to the upper and lower ends of the back plate, and a locking block provided on the upper buckle plate and the lower buckle plate.

[0006] Preferably, both the upper buckle plate and the lower buckle plate are provided with buckling marks, and the upper buckle plate and the lower buckle plate can buckle the side of the connection frame during the assembly of the pin-header seat and the female-header seat.

[0007] Preferably, a card slot is opened on the side of the connection frame, and the card slot can be adapted to the locking blocks on the upper buckle plate and the lower buckle plate.

[0008] Preferably, the connection frame and the female-header seat, the pin-header seat can be connected by gluing, welding or pressing parts.

[0009] Preferably, the two snap units are connected by welding, and the splicing dimension of the two snap units is adapted to the sum of the lengths between the two connection frames during the assembly of the pin header socket and the female header socket.

[0010] Preferably, the two snap units are connected by a tension spring. When the tension spring is in an extended state, the splicing dimension of the two snap units is greater than the sum of the lengths between the two connection frames during the assembly of the pin header socket and the female header socket.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By providing a connection frame outside the female header socket and the pin header socket, the connector of the present utility model uses an external snap module to snap and lock the connection frame, thereby keeping the female header socket and the pin header socket tightly connected and avoiding the situation of connection slippage.
