Abstract
The utility model discloses a contact terminal (1) formed by bending a metal plate, comprising a welding part (11) and an elastic contact arm (13) obliquely extended out upward on one side of the welding part. The contact arm comprises an arc connecting part (14) extended out from the side, a connecting arm (131) extended from the end of the connecting part and a contact part (132) located at the end of the connecting arm, and the connecting part comprises a first connecting part (141) and a second connecting part (142) bent upward twice in the extension direction. The first connecting part and the second connecting part are capable to avoid excessive welding and improve the stability of the terminal contact arm.
Description
[technical field]
The utility model relates to a kind of contact terminal, and the one end is directly fixed on circuit board, and the other end is in order to electrically to reach other electronic devices and components of mechanical connection.
[background technology]
At present the contact terminal of using generally is that an end permanently is welded in circuit board, and the other end is Mechanical Contact electronic devices and components flexibly then, to finish both electrically conducting.Such as present on the market cover-slide-type handset, mobile phone generally comprises pedestal and slide, and contact terminal can be used as electrically conducting between two interior circuit boards of pedestal and slide.By both slide relative, make pedestal and slide be superimposed or the part released state, contact terminal then transmits the information of both above-mentioned states.Contact terminal directly is exposed between two circuit boards, needs the larger area welding, still, the weldering phenomenon of overflowing takes place inevitably.So, wish to design a kind of contact terminal of weldering phenomenon of can effectively avoiding overflowing to the electric property influence.
[utility model content]
Technical scheme to be solved in the utility model provides a kind of contact terminal of weldering phenomenon to the electric property influence of effectively avoiding overflowing.
The purpose of this utility model is achieved through the following technical solutions: a kind of contact terminal, it is bent to form by a sheet metal, comprise weld part and from the weld part one side extended elastic contact arm that is inclined upwardly, contact arm comprises that connecting portion comprises first, second connecting portion that is bent to form by twice on the direction of its extension from the extended arc connecting portion of side, from the terminal linking arm that extends of connecting portion and be positioned at the contact site of linking arm end.
Compared to prior art, contact terminal of the present utility model can be avoided overflowing and weld phenomenon, and can improve the stability of termination contact arm.

Fig. 1 is the stereogram of the utility model contact terminal.
Fig. 2 is the stereogram of another angle of contact terminal.
Fig. 3 is the cutaway view along the A-A line of Fig. 1.
[embodiment]
Shown in ginseng Fig. 1 to 3, contact terminal 1 is to be bent to form by a metallic plate, and it comprises that the base portion 11 of rectangle and a pair of arm 12, two arms that extend from the two edges of a side 111 of base portion keep at a certain distance away.One contact arm 13 is inclined upwardly from the side between two arms 111 of base portion and extends.Contact arm 13 comprises from the base portion side continuous arc that makes progress and bends the connecting portion 14 of twice formation, and this connecting portion comprises that first, second connecting portion 141,142, the first connecting portions 141 are curved portions up, and second connecting portion 142 is curved portions down.Linking arm 131 extends from the free terminal of second connecting portion 142, and is a linearity, and the free terminal of linking arm 131 bends downwards, forms a contact site 132, and this contact site can be for the Elastic Contact of other or external electronic component.
Upwards the arc connecting portion 14 of bending can effectively be avoided the excessive weldering phenomenon of weld part when being welded in circuit board.Ginseng Fig. 3, when weld part was welded in circuit board, part or unnecessary scolding tin can flow to first connecting portion 141 (as arrow B), because of the first upwards bending of connecting portion 141, distance between itself and the weld part bottom surface has increased, and corresponding space has also increased, and the scolding tin that can Gong overflow holds.Because of first connecting portion 141 is curved portions upwards, the direction of its extension will be shown in the dotted line C of Fig. 3, and because of the height of linking arm 131 can be restricted, linking arm may the direction shown in dotted line D bend, that corresponding R angle will be bigger, and the stability of linking arm will reduce greatly.Downward second connecting portion 142 of the present utility model can be avoided this situation, and it is bigger that the R angle of linking arm 131 need not be designed, and certainly, this connecting line can reach the straight line situation, guarantees linking arm stability preferably.
