Description

The board to board connector locating device

The utility model relates to a kind of board to board connector locating device, is meant a kind of board to board connector locating device that the socket and plug inlay card can be located especially.

Board to board connector is used for printed circuit board (PCB) is connected to each other, this type of connector is usually used in portable computer, relevant technology is at United States Patent (USP) the 5th, 057, No. 027, the 5th, 112, No. 235, and Taiwan patented claim No. 80105936, No. 81216612, No. 83209060, and among the flat 3-173337 of Japanese patent application, 3-3595550,4-212046 description is arranged all.But, the shortcoming that haves much room for improvement below in these board to board connectors that disclosed, all existing, that is:

(1) assembly cost height--have good flatness in order to keep the socket and plug terminal, the weld part position of terminal is controlled easily, can effectively weld with circuit board easily, therefore on the insulation shell of socket and plug, add a pressing plate (SPACER), so not only increase the mould expense and increase assembly cost because of part more.

(2) the pin problem that collapses can appear in the terminal on the socket--because manufacturing tolerance and when butt joint are inserted the relation of angle, and directly utilize the plug upper terminal to do guiding and can't be used by the improper extrusion pin that causes collapsing because of the terminal on the socket when making the socket and plug butt joint.

(3) plug docks the loose contact of back terminal with socket--because the no ad hoc device of replacing between the socket and plug terminal, so terminal and terminal mutual contact uncertain.Easily cause the electric signal transmission unstable during actual the use.

(4) socket and plug terminal resistance value is too high--and the socket and plug upper terminal does not have energy storage (Preload) design, cause terminal and terminal containing slot inwall gap (Gap) uncontrollable, therefore, under the different contact force pressure of each terminal, cause part terminal resistance value too high easily, influence the electric signal stable transfer.

(5) locating effect is bad between the socket and plug--because connector is not provided with locating device, the fine location of Chang Buneng between socket and plug.

The purpose of this utility model is to provide a kind of board to board connector locating device, can be with fine location of socket and plug and interlocking, more expediently with the circuit board solid welding.

The purpose of this utility model is to realize like this, a kind of locating device of board to board connector promptly is provided, be used for the socket and plug inlay card and affixed with circuit board, it comprises the plate body with inlay card section, extension and canned paragraph, an and caulking groove, described caulking groove is located at the both sides of described socket and plug insulation shell, the inlay card section of described plate body is provided with hangnail with described socket and plug inlay card at the corresponding caulking groove wall of plate body, described extension is along the moulding of described insulation shell outline, and described canned paragraph is for to develop and the plane affixed with circuit board with circuit board.

The advantage of the utility model device is.The locating device of this board to board connector can remain on socket and plug on the tram respectively, makes the accurately inlay card butt joint of socket and plug energy of connector, and the location is firm, and benefits realization and the intact solid welding of circuit board.
