And it is disclosed on the market at present by cover-slide-type handset that pedestal and slide constituted, as TaiWan, China patent application case number No. 093101461, No. 093209318 etc., can be by at least one contact terminal as electrically conducting between two printed circuit board (PCB)s in pedestal and the slide, as shown in Figure 2, existing contact terminal 1a comprises that one is the base portion 11a of long strip-board shape, base portion 11a end is formed with solid welding sheet 12a, with with the pedestal of cover-slide-type handset in printed circuit board (PCB) solid welding mutually, the other end of base portion 11a then upwards bends an elastic plate 13a parallel and separated by a distance with base portion 11a, being formed with on the elastic plate 13a can be for the adsorption plane 131a of the absorption of the suction nozzle on SMT board usefulness, the end of elastic plate 13a then bends one again and is circular-arc contact site 14a, the contact site 14a conducting that can contact with the printed circuit board (PCB) upper contact in the slide of cover-slide-type handset.
Yet 13a has elasticity because of elastic plate, and causes suction nozzle to be difficult for adsorbing contact terminal 1a, and then influences whole production flow process speed, even excessive because of suction, and the elastic plate 13a of contact terminal 1a also might produce distortion.
The utility model content
In order to solve in the above-mentioned prior art for because of elastic plate has elasticity, and cause suction nozzle to be difficult for adsorbing the technical problem of contact terminal, the utility model spy provides a kind of contact terminal structure.
For achieving the above object, contact terminal of the present utility model is with pedestal and printed circuit board (PCB) slide in the mutually telecommunication connection of surface mount mode (Surface MountTechnology is called for short SMT) with slide electronic device.Wherein, contact terminal comprises the base portion of a long strip-board shape, base portion one end extends the solid welding sheet, solid welding sheet and the interior printed circuit board (PCB) solid welding mutually of pedestal, the other end at base portion then upwards bends an elastic plate parallel and separated by a distance with base portion, being formed with on the elastic plate can be for the adsorption plane of the absorption of the suction nozzle on SMT board usefulness, and the end of elastic plate then bends one again and is circular-arc contact site, the conducting that contacts of the contact on the interior printed circuit board (PCB) of contact part and slide.Wherein, contact terminal upwards is bent with a support arm respectively at the place, both sides of base portion and extends to the elastic plate end face, and adsorption plane downward and elastic plate fastens.
As mentioned above, the utility model is resisted against on the elastic plate by this support arm, and the supported arm of elastic plate is fastened can't be toward top offset, and strengthens the adsorption plane intensity of elastic plate, the suction nozzle that makes the SMT board can be more easily when the absorption contact terminal, to increase production procedure speed person.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the stereo appearance figure of the utility model contact terminal.
Fig. 2 is the stereo appearance figure of existing contact terminal.
Among the figure, 1. contact terminal, 11. base portions, 111. collection molten tin baths, 12. solid welding sheets, 121. solder collecting holes, 13. elastic plates, 131. adsorption planes, 14. contact sites, 15. support arms.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
In the utility model, contact terminal 1 is applied on the cover-slide-type handset (not shown), general cover-slide-type handset is the slidingtype cooperation by the slide that a pedestal and with operating surface has display surface, by the two slide relative, makes pedestal and slide be the state of coinciding or part released state.Therefore, place, at least one side at the cover-slide-type handset pedestal is provided with surface mount mode (Surface Mount Technology, be called for short SMT) with pedestal and slide in the printed circuit board (PCB) contact terminal 1 that connects of telecommunication mutually, seeing through this contact terminal 1 is the message that is the state of coinciding or is the part released state to transmit pedestal and slide.
Please refer to shown in Figure 1, contact terminal 1 includes a base portion 11 that is long strip-board shape, base portion 11 1 ends extend solid welding sheet 12, solid welding sheet 12 and the interior printed circuit board (PCB) solid welding mutually of pedestal, then upwards bend an elastic plate 13 parallel and separated by a distance at the other end of base portion 11 with base portion 11, being formed with on the elastic plate 13 can be for the adsorption plane 131 of the absorption of the suction nozzle on SMT board usefulness, the end of elastic plate 13 then bends one again and is circular-arc contact site 14, contact site 14 be with slide in printed circuit board (PCB) on the contact conducting that contacts.
Wherein, contact terminal 1 upwards is bent with at least one support arm 15 in the side edge of base portion 11, and support arm 15 extends to elastic plate 13 end faces.In present embodiment, support arm 15 is two and all props up elastic plate 13 end faces.When the suction nozzle on the SMT board adsorbed the adsorption plane 131 of usefulness, support arm 15 propped up elastic plate 13 end faces, made the adsorption plane 131 supported arms 15 of elastic plate 13 fasten and can't cause distortion to avoid elastic plate 13 because of the suction of suction nozzle toward top offset.In addition, on the solid welding sheet 12 of these base portion 11 1 ends, be provided with a solder collecting hole 121, and be formed with collection molten tin bath 111 at the side of base portion 11.
