Description

Board to board connector

Affiliated technical field

The utility model relates to a kind of connector, relates in particular to a kind of board to board connector that can firmly be welded on the circuit board.

Background technology

Board to board connector is a kind of connector that is applied to electronic product inside, is used for realizing that the signal between two circuit boards transmits.

Usually, board to board connector comprises the pin connector and the socket connector of mutual grafting.This pin connector is welded on the corresponding circuit board by the weld part of its conducting terminal respectively with socket connector, so that connector is fixed to one another with corresponding circuit board respectively.When this pin connector inserts this socket connector, can reach the electric connection between two circuit boards.

But along with the lightening day by day development trend of electronic product, the conducting terminal of board to board connector also is tending towards miniaturization gradually.This is not enough to the solder bond power that provides enough big between connector and circuit board with regard to the weld part that has caused the board to board connector terminal.Especially plug repeatedly or contact engaging and separating force when excessive at connector, the weld part that very easily makes conducting terminal breaks away from and influences the normal transmission of signal the electronic product from circuit board.

At this phenomenon, the United States Patent (USP) the 5th that on April 6th, 1993 was announced, 199, disclosed a kind of connector for No. 884 with bonding pad, yet the weld strength that its bonding pad provides still can not satisfy actual needs, and the assembling process of this bonding pad on connector is also comparatively loaded down with trivial details, is unfavorable for improving the packaging efficiency of connector.

The utility model content

The utility model purpose is to provide a kind of board to board connector at the defective that above-mentioned prior art exists, and reaching the stable welding of board to board connector and circuit board, and is convenient to the assembling of board to board connector.

For achieving the above object, the utility model provides a kind of board to board connector, comprises the socket connector and the pin connector of mutual grafting.This socket connector comprises that one first body, some the first terminals and first help weld tabs.This first body has two first side walls and two second side walls that are oppositely arranged, the formation one of giving a farfetched interpretation downwards of the two ends of this second side wall end face middle part and first side wall is the deep-slotted chip breaker of " U " shape, and this deep-slotted chip breaker at least a portion at the two ends of first side wall and the second side wall place runs through first body downwards and forms first containing hole and second containing hole.This first helps weld tabs to have a main part that is " U " shape, to be inserted in the described deep-slotted chip breaker; At least one welding foot is extended at these main part two ends and middle part respectively downwards, and described welding foot is inserted in first containing hole and second containing hole respectively and exposes first body.This pin connector comprises that one second body, some second terminals and second help weld tabs.This second body has two the first side walls and two second sidewalls that are oppositely arranged, and the bottom surface of this second sidewall offers the inserting groove that extend front and back, and at least a portion of this inserting groove runs through described second body and forms spliced eye.This second straight-arm that helps weld tabs to have a transverse arm and vertically extend to form by transverse arm, this second helps weld tabs to be inserted in the described inserting groove, and this straight-arm is inserted in the spliced eye and exposes second body.

As mentioned above, first help weld tabs and second to help weld tabs by what be provided with in the board to board connector, the utility model board to board connector can have bigger adhesion when being welded in circuit board, so that more stable electric connection to be provided, simultaneously, because this first helps weld tabs and second to help weld tabs simple in structure, also can improve the packaging efficiency of board to board connector.
