Embodiment
In more detail with reference to accompanying drawing, at first with reference to Fig. 1 and Fig. 4-8, the present invention specifically comprises a card connector, mark prevailingly with 12, it comprises insulation shell, marks prevailingly with 16, sheet metal shell with the compression molding that covers insulation shell marks prevailingly with 18.From Fig. 1 as seen, housing is equipped with a plurality of conducting terminals, marks prevailingly with 20, and they are installed on the housing with the afterbody that array format side by side crosses housing.Housing and metal shell 18 mark (Fig. 7) prevailingly in conjunction with forming the chamber with 22, in order to receive storage card, mark prevailingly with 24, and storage card inserts the preceding reception area 26 (Fig. 4) of connector according to the direction of joint " A ".
Can see better that from Fig. 1 when inserting connector with suitable direction, storage card 24 comprises leading edge 28, trailing edge 30, plane 32, top and baseplane 34.Cutting forms a plurality of contact grooves 36 on plane 32, top, and the opening of groove is at leading edge 28 places of card.Be provided with contact 38 in the bottom of groove, with the contact part of splice terminal 20.Cutting forms wrong insertion-proof slot 40 on the plane, top 32 of card.At last, at a side cutting formation groove 42 of card, below will describe.
Insulation shell 16 has best image in Fig. 2, but also combines with Fig. 1.Housing is normally L shaped, defines in the terminal assembly section 44 of housing afterbody horizontal expansion and the longitudinal side wall district 46 with thin base plate 46a.Sidewall region is extended forward at an end of rear terminal assembly section 44, common form right angle, and comprise side wall block 46b.Guide rail 46c is parallel to the longitudinal side wall district and extends towards side wall block 46b.A plurality of terminal-receiving passages 48 extend through rear terminal assembly section 44.Also will more specifically describe below, latch boss 50 is outwards outstanding from the rear surface of terminal assembly section.At last, the far-end in terminal assembly section 44 forms top fitting recess 51a, forms two top fitting recess 51b and 51c on the top of side wall block 46b, so that metal shell 18 is assembled on the housing, will describe below.
With reference to Fig. 3, and in conjunction with Fig. 1 and 2, each terminal 20 comprises the contact arm 22a that is hung to forward in the card reception cavity 22, and it is being used for and is being positioned at the contact part 20b termination that storage card 24 each each contacts 38 that contact groove 36 engage.Contact arm 20a is outstanding forward from assembling matrix (base) 20c of terminal, and this assembling matrix is pressed against in each interior terminal-receiving passage 48 of the terminal assembly section 44 of housing.The welding afterbody 20d of terminal is projected into the outside of housing afterbody, and ends at the welding backing 20e that is used to be welded to each circuit trace (not shown) on the printed circuit board (PCB).Housing has a plurality of assembling stake 53 (Fig. 6-9), is used to insert pilot hole suitable on the printed circuit board (PCB).
Be equipped with and push away/pull-type card ejection mechanism in the longitudinal side wall district 46 of housing 16, marks prevailingly with 52 in Fig. 1.Providing and playing card structure is that it is known type in this area for ejection from connector and taking-up storage card 24.Below be enough to explanation, play mechanism for card and comprise the slide 54 that can on the base plate 46a in longitudinal side wall district 46, slide, slide is forced to the wind spring 56 of the preceding reception area 26 (Fig. 4) of connector, the pin member 58 that combines with heart-shaped cam groove (not shown) in the slide.Push away/pull-type card ejection mechanism 52 is well known in the art.When being inserted into storage card 24 in the card reception cavity 22, the groove 42 of card side blocks the hammerlock 60 of slide, makes slide move along direction of insertion with card, simultaneously coil compression springs 56.When pulling out card, under the effect of wind spring 56, card ejects from the card reception cavity.Imaginary line among Fig. 4-6 shows the initial and complete insertion position of storage card.
With reference to Fig. 1 and Fig. 4-8, metal shell 18 is molded and moulding by sheet material, and is enough to cover basically the whole zone that insulation shell 16 is limited.Metal shell comprises and covers top board 66 and a pair of trend opposite side wallboard 68 and 70 for along hanging of the front-posterior direction of connector.Sidewall paneling 68 covers the longitudinal side wall district 46 that plays mechanism for card 52 and housing.Sidewall paneling 70 limits the opposition side of card reception cavity 22, and this has best image in Fig. 4 and 7.A plurality of fitting joint (tab) 72a of of hanging, 72b and 72c are molded and shaped and go out from shell, being pressed into the top fitting recess 51a of housing respectively, among 51b and the 51c.Latch tab 74 at the afterbody of metal shell has opening 74a, is used for latch boss 50 interlocks with housing.Therefore, when shell is assembled to housing, the fitting joint 72a-72c of shell by the fitting recess 51a-51c that compresses into housing, and latch boss 50 interlocks of the latch tab 74 of shell and housing.
Metal shell 18 also has anti-mis-insertion projection 76, and it is from overlay 66 molded and shaped the forming of shell, and it will be suspended in downwards in the groove 40 of top surface 32 of storage card 24 (Fig. 1) will blocking when suitably being inserted into connector.When will block positive and negative or put the cart before the horse insertion, projection 76 prevents that card from engaging with the contact part 20b of terminal 20.
The sidewall paneling 70 of metal shell 18 comprises a plurality of parts, specifically with reference to Fig. 9.At first, outwardly-bent on the base of sidewall paneling have at least one fitting joint 80 that has pilot hole 80a, and it is fitted on connector device on the circuit board.Secondly, the sidewall paneling 70 of metal shell is included in the aduncate vertical bottom flange 82 in base of sidewall paneling, is used for guiding storage card 22 turnover from the chamber.The 3rd, sidewall paneling 70 comprises the slide protrusion 84 that extends in the chamber, is used to engage the side of storage card, so that reduce when card passes in and out from the chamber and the friction that blocks.Can find out better that from figure slide protrusion 84 is narrow projections that extend along the activity direction of storage card, and from sidewall paneling 70 embossing (emboss) inwardly.
At last, a metal assembling nail 86 (Fig. 1 and 6) is inserted downwards in the groove 90 (Fig. 2) of opening 88 (Fig. 1) in the metal shell 18 and housing 16, the same with welding, connector is fixed on the assembling liner suitable on the printed circuit board (PCB).
Can know the rear terminal assembly section 44 of L shaped housing 16 and an afterbody and the side that longitudinal side wall district 46 forms card reception cavity 22 from noted earlier.Metal shell 18 comprises overlay 66 and sidewall paneling 70, and they form the top and the opposite side in this chamber respectively.The combination of this uniqueness has reduced the size and the weight of whole connector.
At last, Figure 10 illustrates alternative of the present invention, and the sidewall region 46 of its middle shell 16 moves on to the opposed end of rear terminal assembly section 44 from first embodiment shown in Fig. 2 the best.Alternative hereto, the sidewall paneling 68 of metal shell 18 and 70 is just put upside down simply, and connector just constitutes and operation similarly similarly.In addition, the housing of alternative will form the afterbody and a side of card reception cavity, and metal shell will form the top and an opposite side in this chamber, also reduce the size and the weight of connector in the prior art.
Be appreciated that the present invention can implement with other particular form, only otherwise break away from its spirit or core feature.Therefore, example of the present invention and scheme all should be thought exemplary and nonrestrictive, and the invention is not restricted to details given here.
