Description

Board to board connector

The present invention relates to an electronic connector, and more particularly to a board-to-board connector in which a socket body houses a metal terminal package.

The board-to-board connector is the most powerful connector product in the current connector product category, mainly used in power systems, communication networks, financial manufacturing, industrial automation, medical equipment, home appliances and military manufacturing industries. The existing board-to-board connector is generally a two-piece assembly type, that is, the metal terminal is inserted into the corresponding terminal slot on the socket body, specifically, the metal terminal is inserted into the corresponding terminal slot of the socket body by assembling and riveting. The metal terminal is fixed in the socket body by the bonding of the side wall of the socket body and the metal terminal wall.

However, in the prior art, the tightness between the metal terminal and the socket body is not very good, and at the same time, since the metal terminal is exposed, it is easy to cause the tin to climb, and at the same time, the terminal is easily deformed during assembly, resulting in poor product functionality. In addition, when the board-to-board connector is actually connected, the terminal may be returned to the PIN due to the poor connection between the terminal and the terminal slot of the socket body.

The main purpose of the present invention is to provide a board-to-board connector in which the terminal body of the socket body completely encloses the metal terminal in a buried molding manner, so that the metal terminal and the socket body are integrated, thereby achieving close fixation of the two.

Specifically, the present invention provides a board-to-board connector that is made of an insulating material. The socket body is made up of a plurality of conductive materials and is composed of metal terminals held by the socket body, and the metal terminal and the socket body are formed by metal embedded injection molding, and the metal terminal is inserted in the In the recessed receiving groove of the pivot post of the socket body and the slot of the first side wall and the second side wall, the third contact portion of the metal terminal is formed by the slot of the first side wall and the second side wall of the socket body Wrapped in a package.

The socket-to-board connector includes: a central column disposed in a middle of the socket body accommodating space, and defining a first accommodating space with the first side wall and the second side wall respectively And a second receiving space, the central column is provided with a concave receiving groove for receiving the first contact portion and the second contact portion of the metal terminal; a first side wall is a frame of the socket body, and The second side wall is symmetrically disposed via the central column, and the first side wall is provided with a plurality of slots for receiving the third contact portion of the metal terminal; and a second side wall is another frame of the socket body, and The first side wall is symmetrically disposed via a central column, and the second side wall is provided with a plurality of slots for receiving the third contact portion of the metal terminal; and the board-to-board connector is mounted, the metal terminal The first contact portion is inserted into the concave receiving groove of the pivot post of the socket body; the second contact portion is inserted into the concave receiving groove of the pivot post of the socket body; and the third contact portion is Inserted into the first side wall of the socket body and Two sidewalls of the slot, insert injection molding metal the metal is formed by a third contact portions of the terminals of the first and second side walls of the slot-shaped accommodating package.

In the board-to-board connector, the socket body is a plastic material seat.

In the board-to-board connector, the metal terminal and the first side wall and the second side wall are disposed in a package-like manner in an insert molding manner, and the metal terminal is closely held by the socket body.

In the board-to-board connector, the slots on the first side wall and the second side wall are evenly arranged.

The board-to-board connector is provided with two hole positions on the back of the socket body.

This creation has the following distinct technical advantages over prior art board-to-board connectors:

1. The board-to-board connector of the present invention preserves the good springability of the metal terminal by the embedded molding method, and replenishes the strength of the terminal groove of the socket body, and innovates the elastic end of the metal terminal by the embedded molding. It can't move.

2. The splicing board adopts the in-line forming method for the board connector, so that the metal terminal and the socket body are closely engaged to ensure the TAIL coplanarity and position.

3. The embedded board-to-board connector saves the artificial waste caused by the prior art assembly molding, and also protects the metal terminal from deformation, thereby reducing the defect rate of the product.

4. The splicing plate-to-board connector adopts the in-line molding method to effectively avoid the phenomenon of climbing tin caused by the siphon effect in the SMT (surface adhesion technology) process. Moreover, it effectively prevents the terminal that is illuminated due to excessive insertion and extraction force from being detached or even detached when the connector is mated.
