Abstract
The utility model discloses a contact terminal which is formed by a bent metal piece. The contact terminal comprises a base part (11), a welding part (12) arranged on one end of the base part, and a connecting part (13) extended from the other end of the base part. The tail end of the connecting part is bent to form an arc-shaped contact part (15), two side edges of the welding part are bent upwardly to form opposite supporting walls (16), at least partial contact part is positioned between the two supporting walls, and the supporting walls also have buckling arms (161) which are bent oppositely and press downwardly against the contact part or the connecting part so as to give an upward elastic force to the contact part.
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, is different from the conducting terminal in the electric connector, and it does not have the protection of insulating body, and elastic tip may take place provides the not enough or elastic tip of elastic force phenomenon such as can not be replied by the electronic devices and components excessive compression.So it is better to wish to design a kind of elastic force, and can guarantee the contact terminal of electrical contact stabilization.
[utility model content]
But but technical scheme to be solved in the utility model provides the contact terminal of a kind of precompressed and self-protection.
The purpose of this utility model is achieved through the following technical solutions: a kind of contact terminal, it is by a metal
Be bent to form, comprise base portion, be positioned at the weld part of base portion one end and the connecting portion that extends from the base portion other end, the end of connecting portion is bent with an arc-shaped contact part, the dual-side of weld part upwards is bent with relative supporting walls, at least partly the contact site is between two supporting walls, supporting walls also is provided with the button gripping arm of relative bending, compresses contact site or connecting portion downwards, makes contact site have elastic force upwards.
Compared to prior art, but contact terminal precompressed of the present utility model, and can realize the self-protection function.

Fig. 4 is the cutaway view of Fig. 3 along the B-B line.
[embodiment]
Fig. 1,2 has shown the contact terminal of first embodiment of the present utility model, and this contact terminal 1 is by a metal
Be bent to form, it comprises the base portion 11 that is long strip-board shape, and an end of base portion is the weld part 12 in order to be welded in circuit board.The other end of base portion 11 upwards vertically extends first connecting portion 13 earlier, and then to extend second connecting portion, 14, the second connecting portions towards base portion 11 sides be to be parallel to base portion 13.Second connecting portion continues to extend upward the contact site 15 of arc, and contact site is downward opening arch bridge shape, and its free terminal 151 is bent into horizontal.The two sides of weld part 12 upwards vertically bend out two supporting walls 16.Two supporting walls 16 are cutting out a part near outboard end, the button gripping arm 161 that bends inwards out relative then, and other parts of supporting walls continue to extend upward, and until the centre position of contact site 15, form a protective bulkhead 162.151 of the free terminals of contact site flexibly are resisted against button gripping arm 161 belows.
Second connecting portion 14 is roughly horizontal, in order to the adsorption plane of the suction nozzle on the SMT board to be provided.Button gripping arm 161 roughly is positioned on the sustained height with adsorption plane, the free end resilient abutment of contact site is in button gripping arm 161 belows, can realize the elasticity precompressed of contact site 15, promptly hold by the button of button gripping arm, contact site is not with the electronic devices and components contact time, and it has elastic force trend upwards, so, contact site 15 just can produce bigger elastic force under than the situation of small deformation, especially under the less situation of terminal sizes, the effect of this prepressing structure is just more obvious.
The top of protective bulkhead 162 roughly is positioned at contact site 15 position intermediate, and when electronics vigour device contacts contact site 15, contact site 15 will move down, and protective bulkhead 162 can prevent that electronic devices and components from excessively pressing down and cause the destruction problem of contact site.The height of protective bulkhead 162 is by the elastic force size decision that needs between contact site 15 and the electronic devices and components.Be provided with a finedraw 111 between weld part 12 and the base portion 11, it can hold the scolding tin that weld part 12 overflows, and prevents the influence of scolding tin to the contact terminal electric property, also helps the vertical bending of supporting walls 16.
Fig. 3,4 has shown the contact terminal of second embodiment of the present utility model, and contact terminal 2 also is bent to form by a sheet metal, and it comprises base portion 21, and an end of base portion is extended with weld part 22.The other end of base portion 11 upwards vertically extends first connecting portion 23 earlier, and then to extend second connecting portion, 24, the second connecting portions towards base portion 21 sides be to be parallel to base portion 21.Second connecting portion continues to extend upward the contact site 25 of arc, and contact site is downward opening arch bridge shape.The two sides of weld part 12 upwards vertically bend out two supporting walls 26.Two supporting walls 26 are cutting out a part near medial extremity (being adjacent base 21 sides), the button gripping arm 261 that bends inwards out relative then, and other parts of supporting walls continue to extend upward, and until contact site 25, form a protective bulkhead 262.
Second connecting portion 24 is parallel to base portion 21, also can be used as the SMT adsorption plane, and second connecting portion begins to attenuate from touching with contact site 25 handing-over, forms a neck 241, and the lateral dimension of contact site (being width) is roughly suitable with neck, less than second connecting portion.The width of base portion, weld part and second connecting portion is also identical, and two supporting walls vertical extent so the width of contact site is slightly less than the distance between two supporting walls, make things convenient for contact site to move between two supporting walls.Button gripping arm 261 buttons are held neck 241, make contact site 25 precompressed to have certain elasticity.Supporting walls is provided with opening 263, the cross-ventilation when helping to weld.
