Embodiment

About the aforementioned of the utility model and other technology contents, characteristics and effect, in the detailed description of following cooperation, can clearly appear with reference to a preferred embodiment of accompanying drawing.

Before the utility model is described in detail, be noted that in following description similarly assembly is to represent with identical Reference numeral.

Consult Fig. 2～Fig. 6, a preferred embodiment of the utility model electronic card coupler applicable to the Micro SIM of pegging graft to be electrically connected with a circuit board 8.Electronic card coupler 1 comprises: an insulating body 2, a metal cap body 3, many first row's terminals 4 and many second row's terminals 5.

Insulating body 2 is integrally formed with first row's terminal 4 and second row's terminal 5 with the molded mode of flush type (insert molding); Fig. 5 and just explanation for ease of exploded view shown in Figure 6, in fact insulating body 2 and first row's terminal 4 and second row's terminal 5 are undecomposable.Metal cap body 3 is combined with insulating body 2, and defines a socket 61 of a slot 6 and turnover slot 6 jointly.Metal cap body 3 has a plurality of weld parts 31 to be fixedly welded on circuit board 8.

Consult Fig. 2～Fig. 8; First row's terminal 4 is arranged in the position of insulating body 2 near socket 61 at intervals; Each first row's terminal 4 part is embedded in insulating body 2, and terminal to be connected in first elastic arm 43 terminal and protrude out to first contact site 44 in the slot 6, and extend insulating body 3 outer first leg 46 toward the extension 45 and that extends away from the directions of socket 61 and be embedded in insulating body 3 by extension 45 by main body 41 toward tiltedly go up first elastic arm 43, that extends away from socket 61 directions by bend 42 respectively to have bend that a main body 41, extended near the up c-shaped reflexed of an end of socket 61 by main body 41 42.

The relative both sides of main body 41 are embedded in the insulating body 2 and the bottom surface is exposed to insulating body 2, and the bottom surface 411 of main body 41 is a plane and forms a weld zone 412, and have bigger bonding area.Moreover the bottom surface 411 of main body 41 flushes with the bottom surface 21 of insulating body 2, can make electronic card coupler 1 whole height lower, to reach the effect of low clearance (low profile).

Each first row's terminal 4 also has a through hole 47, a slotted eye 48 and a perforate 49 that runs through main body 41.Each first row's terminal 4 also has a plurality of protuberances 40 that extended and be embedded in insulating body 2 respectively by the relative both sides of main body 41, in order to increase the bond strength of main body 41 and insulating body 2.Through hole 47 is positioned at the zone of weld zone 412, and slotted eye 48 is between weld zone 412 and bend 42, and perforate 49 correspondences are positioned at the position that first contact site 44 presses down.In the present embodiment; The both sides, 412 front and back, weld zone of main body 41 connect slotted eye 48 and perforate 49 respectively, consult Fig. 9 and Figure 10, weld pad 81 welding on weld zone 412 correspondences and the circuit board 8; In the zone of weld zone 412; Scolder (not shown) can be sticked together by the edge of slotted eye 48 and the formed vertical plane in edge of perforate 49 in the formed vertical plane in edge and the both sides, 412 front and back, weld zone that utilize through hole 47, makes main body 41 and scolder except the gluing face of bottom surface 411 horizontal directions; Also increase the gluing face of vertical direction, can increase weld strength.Be noted that; Because bottom surface 411 entire area of main body 41 are bigger; Also do not had the bigger bonding area of the prior art compared even weld zone 412 is not provided with through hole 47, and had preferable weld strength, it is also passable therefore through hole 47 not to be set; Can strengthen weld strength again but through hole 47 is set, through hole 47 does not exceed with one certainly.In like manner, the side that slotted eye 48 and perforate 49 are connected with weld zone 412, can be in the weld zone 412 the outside form vertical plane, be increased in the gluing face of vertical direction, and strong weld intensity more, if slotted eye 48 is not set or perforate 49 also is fine.In addition, perforate 49 because perforate 49 is positioned at the position that the first corresponding contact site 44 presses down, and then makes the free end of first contact site 44 can stretch into perforate 49 except in order to increase the weld strength, to reduce the terminal height.

Consult Fig. 2～Fig. 5 again; Second row's terminal 5 is arranged in first row's terminal 4 at intervals away from a side of socket 61, each second row's terminal 5 have one be embedded in insulating body 2 fixed part 51, extend second elastic arm 53 and that the second outer legs 52 of insulating body 2, extend by fixed part 51 by fixed part 51 to be connected in second elastic arm 53 terminal and protrude out to second contact site 54 in the slot 6.At present embodiment.Second elastic arm 53 and first elastic arm 43 extend in the same way, the form of implementation that still changes in equivalence, and second elastic arm 53 and first elastic arm 43 can also oppositely extend.

In the present embodiment; The weld zone 412 of the main body 41 of first row's terminal 4 is the weld strengths that are used for strengthening first row's terminal 4 and circuit board 8; Also increase simultaneously the weld strength of whole electronic card coupler 1 and circuit board 8, and second leg 52 of first row's terminal 4 first leg 46 of also having first leg, 46, the first row's terminals 4 and second row's terminal 5 is staggered in the same side of insulating body 2 and be the side away from socket 61; And the weld pad 82 (consulting Fig. 9) that is welded in circuit board 8 is in order to transmission signals; That is, be a side that is positioned at away from socket 61 in order to first leg 46 and second leg 52 of transmission signals, the external force when receiving the electronic cards plug with respect to adjacent socket 61 places is less; Can avoid when the improper plug of electronic cards or repeatedly after the plug with this; The risk of first leg 46 and second leg, 52 breaking circuit plates 8, and can guarantee the stability that first row's terminal 4 and second row's terminal 5 are electrically connected with circuit board 8, to avoid the problem of loose contact or disconnected news.In the present embodiment; Second leg 52 of first leg 46 of first row's terminal 4 and second row's terminal 5 is staggered in the same side of insulating body 2 and is that a side away from socket 61 is preferable form of implementation; But first leg 46 and second leg 52 can perhaps can all can not change enforcement not being the same side away from socket 61 in the same side of insulating body 2 yet yet.

In sum, main body 41 bottom surfaces 411 of first row's terminal 4 of the utility model electronic card coupler 1 can form larger area weld zone 412 for exposing a plane of insulating body 2 bottom surfaces 21; Can increase the solder bond intensity of electronic card coupler 1 near socket 61 places; Make electronic card coupler 1 be difficult for the breaking circuit plate, to avoid the problem of loose contact or disconnected news, further; Main body 41 bottom surfaces 411 flush with the bottom surface 21 of insulating body 2; Can make electronic card coupler 1 whole height lower, to reach the effect of low clearance, so can reach the purpose of the utility model really.

Yet the above is merely the preferred embodiment of the utility model; Can not limit the scope that the utility model is implemented with this; Be that all simple equivalent of being done according to the protection range and the utility model description of the utility model change and modification, all still belong to the scope that the utility model patent contains.
