Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a board-end multi-pin connector. 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, in the existing multi-pin connectors, in order to realize the setting of the connector, a welding plate is generally specially provided to fix the plastic shell to the board body, so as to reduce the force on the PIN pins, resulting in damage to the board body or loosening of the PIN pins. The main factor is that one of the sides of the plastic shell contacts the board body, so the force fulcrum is unbalanced. Utility Model Content

[0004] The main purpose of the utility model is to propose a board-end multi-pin connector, aiming to design a multi-pin connector structure with a simple structure. The structure is simple and stable, and the male terminal and the female terminal can be inserted stably, and the coaxiality of the male terminal can be guaranteed.

[0005] To achieve the above object, the utility model provides a board-end multi-pin connector, comprising:

[0006] A male connector, wherein a first plate body is vertically arranged on the male connector, and two rows of PIN pins are arranged on the male connector, and first soldering feet are arranged at the rear ends of the PIN pins, and the two groups of first soldering feet are extended outwardly away from the center line of the male connector;

[0007] A female connector, the female connector is vertically arranged on the second plate body, the female connector is provided with a female slot, the female slot is provided with a female terminal, the PIN needle can extend into the female slot and contact the female terminal, the rear end of the female terminal is provided with a second soldering foot, and the second soldering foot is extended outwardly toward a position away from the center line of the female connector;

[0008] The opposite end surfaces of the male head and the female head are respectively provided with a first guide portion and a second guide portion, and the first guide portion and the second guide portion fit each other.

[0009] In the actual design, the PIN needle can be integrally injection molded with the male head or adopt an inserted structure. By setting the first welding foot and the second welding foot outward, the contact area between the board body and the welding foot is made larger, and the outward extension setting can make the plugging and unplugging pressure act on the plastic part of the male head and the female head, reducing the stress on the terminal and the stress on the welding foot and the board body, effectively improving the stability of the connector, and the structure is simple.

[0028] In the actual design, the PIN needle 11 can be integrally injection molded with the male connector 1 or can adopt an inserted structure. By setting the first welding foot 12 and the second welding foot 22 outward, the contact area between the board body and the welding foot is made larger, and the outward extension setting can make the plugging and unplugging pressure act on the plastic part of the male connector 1 and the female connector 2, reducing the stress on the terminal and the stress on the welding foot and the board body, effectively improving the stability of the connector, and the structure is simple.
