Abstract

The utility model provides a connector for a memory card, which mainly comprises a shell body has a front end trough body and two lateral arm bodies, two metal bodies which are respectively installed inside the two lateral arm bodies of the shell body, and a plurality of terminals which are installed inside the trough body on the front end of the shell body. Both lateral arm bodies of the shell body respectively have a turning arm which can be turned outwards, an inclined salient press part, and a convex ring part which projects inwards. When the memory card is plugged into the shell body and is pressed down till the memory card is positioned, the convex ring parts which project inwards of both lateral arm bodies can be respectively contained outwards inside concave walls which are arranged on both sides of the memory card, and the inclined salient press parts of the turning arms on both sides are pressed on the upper part of a plate body of the memory card at the same time, so that a stable combining relation can be kept between the memory card and the connector. When the turning arms on both sides of the shell body are turned and opened outwards, the limitation of the convex ring parts and the salient press parts of the shell body of the connector on the concave walls and the plate body of the memory card can be relieved, so that the memory card can be taken out or replaced conveniently.

Specific embodiment

Structure of the present utility model, characteristics and effect thereof, the embodiment of adjoint is described in more detail as follows.

The utility model connector A consists predominantly of: a housing 1, two metallic objects 2, a plurality of terminal 3.

As shown in the figure, the utility model housing 1 includes front end cell body 11 and two side arms body 12; Being " ㄇ " shape connects.Pilot trench 111 and lower end pilot trench 112 can insert upper terminal 31 and lower terminal 32 respectively for laying respectively at cell body outer end and the inner on this cell body 11 had.These cell body 11 inner notches 113 that form, the inner upper wall of this notch is a tiltedly interior ancient piece of jade, round, flat and with a hole in its centre 114 that is downward-sloping.The structure of above-mentioned this two side arms body 12 is in full accord, its have base plate 121 and be L type arm directly to pulling arm 122, this base plate and directly lack seam 123 to pulling to be provided with between the arm makes this directly have the elasticity of closing in can be by outer to pulling arm 122.Should directly form the inwardly skew wall 124 under declivity to the end face of pulling the arm close end, this skew wall bottom surface is a short slot 125, make the bottom surface sections of this skew wall form the projecting pressing part 126 of a platform, an appropriate location of this skew wall inner edge is more to projecting inward formation one projecting ring section 127 again.One end ecto-entad of above-mentioned this base plate 121 is provided with the slot 128 of depth.

As shown in Figure 3, the structure of above-mentioned two metallic objects 2 is in full accord, and it has a planar substrates 21, this substrate one side linking arm body and extend back forward and protrude in the substrate two ends, this arm body rear end bends inwards and forms L shaped pin 22, and this arm body front end then outwards upwards is connected with straight stopper 23.This metallic object 2 is inserted in the slot 128 of arm body base plate 121 with its L shaped pin 22, and simultaneously, the straight stopper 23 of this metallic object also is inserted in the short slot 125 inboard appropriate locations of pulling arm 122, according to this, finishes firm combination of

metallic object

2 and 12 of housing 1 two side arms bodies.

To shown in Figure 8, above-mentioned this terminal 3 includes a plurality of upper terminals 31 and lower terminal 32, can be inserted in the upper end pilot trench 111 and the lower end pilot trench 112 of housing 1 front end respectively as Fig. 5.This upper terminal 31 includes a strip straight-arm 311, the outwards outstanding welding foot 312 that extends to form in this straight-arm bottom, each inwardly outstanding extension of end position forms contact arm 313 and fixed arm 314 respectively in this straight-arm top and approximately for other, this contact arm end is provided with the protuberance 315 of downward protrusion, can do contacting on electric with the positive set contact 41 of memory card 4 leading sections, this fixed arm then is provided with ratchet 316, to strengthen the fixing of 111 of itself and upper end pilot trench.Above-mentioned lower terminal 32 also includes strip straight-arm 321, welding foot 322, contact arm 323, fixed arm 324, protuberance 325, ratchet 326, and only this protuberance 325 is protruding upward, can do contacting on electric with the positive set contact 42 of memory card 4 leading sections.

Connector is to do welding on electric with the welding foot 312,322 of each terminal 3 and circuit board (not icon), and in addition, the substrate 21 of metallic object 2 is welded on the circuit board, strengthening the bond strength between whole connector and circuit board, and makes the usefulness of ground connection.

As Fig. 1 and shown in Figure 9, above-mentioned this memory card 4 includes a plate body 43, which is provided with internal memory (not icon), and these plate body both sides respectively are provided with and the above-mentioned arm 122 projecting ring sections 127 corresponding recess 44 of pulling.

At plant memory card 4 when connector A uses, be with notch 113 inside of this memory card front end according to this housing 1 front end of the oblique insertion of housing 1 oblique inwall 114 angles, and then these internal memory 4 plate bodys 43 are pressed down, in the process of pressing down, this plate body can be forward the location that arrives by the skew wall 124 of housing 1 two side arms body 12 naturally, at this moment, the projecting ring section 127 that housing 1 is pulled arm 122 is contained in the recess 44 of memory card 4 both sides respectively, simultaneously, the projecting pressing part 126 of housing two side arms body 12 also is pressed on plate body 43 tops of memory card, make this memory card 4 and connector A keep firm marriage relation, and the contact 41 of this memory card front end positive and negative, 42 contact with upper terminal 31 and following son 32 respectively.

When desire is taken out or is changed memory card 4, then the arm 122 of pulling with housing 1 both sides wall body 12 outwards pulls open, can remove the projecting ring section 127 of connector and projecting pressing part 126 respectively to the restriction of the recess 44 and the plate body 43 of memory card 4, this RAM (random access memory) card is oblique naturally the upspringing according to the oblique angle of the oblique inwall 114 of housing 1 front end immediately, but and the supplier just takes out.

In addition, please cooperate shown in Figure 9ly again, with SMT mode weld metal body 2 time,, can respectively install a metallic gasket 5 again additional in these two metallic objects, 2 substrates, 21 bottoms for guaranteeing the evenness of this metallic object bottom surface.The structure of this two metallic gasket 5 is in full accord, it has the base portion 51 that is the plane, has a stria 53 between a pair of trip 52, two trips protruding upward in the middle of the flat base, make the trip 52 outer effect of opening that contracts in having, flat base 51 each side is provided with barricade protruding upward 54 again.When metallic gasket 5 inserts the set circular hole 24 of metallic object 2 substrates 21 with its trip 52, can engage mutually, and can finely tune both up and down so that combination smoothly, 54 edges that can fasten substrate 21 of the barricade of the left and right sides are to increase the stability that above-mentioned this item is finely tuned up and down.Then, utilize again these metallic gasket 5 base portions 51 smooth bottom surfaces carry out and circuit board between SMT welding.

In sum, the memory card connector of the novel structure that the utility model provides has novel creativity and obvious improvement.
