Embodiment

For ease of better understanding the utility model, now in conjunction with the accompanying drawings a preferred embodiment of the present utility model is described in detail as follows:

As shown in Figure 2, the utility model electronic card coupler 1 comprises a metal shell 10, an insulating body 20, places a plurality of conducting terminals 30 in this insulating body 20, with at least one pivot joint earth terminal 40.This pivot joint earth terminal 40 can articulate metal shell 10 and insulating body 20.

Please in conjunction with Fig. 3, this metal shell 10 comprises the two side 12 that a loam cake 11 reaches from these loam cake 11 both sides approximate vertical protrude out, can supply an electronic cards (not icon) to be inserted to pivot end 102, and be contained in the receiving space 13 of this loam cake 11 and sidewall 12 formations by insertion end 101.

Two side 12 is respectively equipped with an articulated section 121 at pivot end 102.Also roughly equidistantly be extended with a plurality of and Access Divisions 122 loam cake 11 plane almost parallels on the sidewall 12 in addition to receiving space 13 1 sides, Access Division 122 1 side direction insertion ends 101 near insertion end 101 are extended a contact chip 123, and these contact chip 123 free ends are the shell fragment that protrudes out contact site 124.

This loam cake 11 extends an auxiliary articulated section 111 at pivot end 102 relatively near 12 places, two side, and this auxiliary articulated section 111 is after loam cake 11 extends one section, and it is near the approximate vertical bending again of two side 12 sides.Slightly one L shaped butting section 112 is arranged from loam cake 11 between the two auxiliary articulated sections 111 to receiving space 13 diagonally extendings.When electronic cards is inserted receiving space 13, can be butting section 112 through pushing and prop up, thereby but assisting users is inserted to the tram with electronic cards.

Insulating body 20 roughly is H shape, and wherein respectively there is a pair of auxiliary earth terminal containing slot 211 position of H shape two arms 21 symmetries, is used to accommodate auxiliary earth terminal 50; The transverse part 22 of H shape is provided with a plurality of conducting terminal accepting grooves 221, is used to accommodate corresponding conducting terminal 30.This auxiliary earth terminal 50 has a weld part 51, and roughly is the contact site 52 of twice vertical bending from these weld part 51 1 sides, and from these weld part 51 opposite sides holding parts 53 of the vertical bending in middle part approximately.This holding parts 53 can be fastened in the draw-in groove that accepting groove 211 forms at insulating body 20 lower surfaces 201 (not shown, as to please refer to the position of holding parts 53 among Fig. 5), thereby auxiliary earth terminal 50 is immobilizated in accepting groove 211.This auxiliary earth terminal 50 is for strengthening the effect of filtering electromagnetic interference, can according to circumstances considering whether to be provided with or to adopt other suitable shape in the present embodiment.Two arms, 21 1 ends are pin joint seat 212.Respectively be provided with the first pivot connected slot 213a, the second pivot connected slot 213b on outer, the inboard of this pin joint seat 212 and accommodate articulated section 121 and auxiliary articulated section 111, and body 20 lower surfaces 201 depressions that insulate certainly have a holding slot (not shown, as to please refer to the position that holds that articulates earth terminal 40 among Fig. 5).Corresponding with the Access Division 122 on the metal shell 10, H shape two arms 21 of insulating body 20 are provided with buckling groove 214 relatively.Buckling groove 214 comprises the first buckling groove 214a and the second buckling groove 214b, is the first buckling groove 214a near articulating metal shell 10 sides wherein, is the groove formula; The second buckling groove 214b is then only from lower surface 201 upwards cave in one section (please simultaneously with reference to Fig. 5).

Articulating earth terminal 40 is a bending sheet metal, have weld part 41, the pivot joint alar part 42 of this weld part 41 1 side approximate vertical extension, and certainly relative opposite side certainly that can be soldered on the circuit board (not icon) and bend the holding parts 43 that extends in the same way with pivot joint alar part 42.Pivot joint alar part 42 about middle parts are provided with first pivoted hole 420 and second pivoted hole 421 of connection, being through to weld part 41 along this second pivoted hole 421 is a transition passage 422 (this transition passage 422 also can be through to weld part 41 from first pivoted hole, 420 places), this transition passage 422 is slightly narrow than second pivoted hole 421, so can enter second pivoted hole 421 under the user promotes for articulated section 121.Holding parts 43 both sides have protruded out a plurality of interference parts 430, and the holding slot inwall of can conflicting produces interference and makes the pivot joint earth terminal 40 stable pin joint seats 212 that are coated on.

Metal shell 10 can be opened and lock dual mode with insulating body 20 and articulate.Be contained in the pivot points (simultaneously) that first pivoted hole 420 defines as Fig. 2 articulated section 121, auxiliary articulated section 111 is contained in the pin joint seat 212 inboard second pivot connected slot 213b by metal shell 10 ends, this moment, metal shell 10 can rotate freely with respect to insulating body 20, was in open state.Metal shell 10 is sticked in insulating body 20 (as Fig. 5), and promotion articulated section 121 enters second pivoted hole 421 from first pivoted hole 420 and defines the position, and also push ahead thereupon auxiliary articulated section 111.As Fig. 4, this moment, Access Division 122 was contained in the second buckling groove 214b, and metal shell 10 lockings are fastened on insulating body 20, and both can not throw off.Auxiliary earth terminal 50 also contacts (in fact, as long as metal shell 10 engages with insulating body 20, both can contact) with contact site 124.So, nationality gets final product effective filtering electromagnetic interference by the articulated section 121 of metal shell 10 and contacting of pivot joint earth terminal 40; Auxiliary earth terminal 50 and contacting of contact site 124 have then strengthened the effect of filtering electromagnetic interference.

The utility model uses and articulates earth terminal pivot joint metal shell and insulating body, and is simple in structure, kills two birds with one stone.Simultaneously can effectively filtering electromagnetic interference, provide the assurance of necessity for realizing high communication quality.

Technology contents of the present utility model and technical characterstic disclose as above, yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and done all replacement and modifications that does not deviate from the utility model spirit.Therefore, protection range of the present utility model should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present utility model and modifications, and is contained by the present patent application claim.
