Embodiment
It is described in detail as follows, and described preferred embodiment only is described in detail, and is not in order to limit the utility model.
At first, please refer to Fig. 2, Figure 2 shows that the decomposing schematic representation of position limiting structure of the card connector of the utility model one embodiment.As shown in the figure, the position limiting structure of card connector comprises: a base plate 10, a metal shell 20, a follow block 30 and an elastic component 40.Wherein, metal shell 20 is by vertical direction, as the dotted line in graphic, engages with base plate 10 to form one and can receive electronic cards or other and insert on the accommodation space of member and the metal shell 20 and have a perforation 22 and two button holes 24.Perforation 22 runs through and is arranged on the metal shell 20 and button hole 24 is arranged at perforation 22 left and right sides and protrude in metal shell 20.Follow block 30 passes to be arranged in the perforation 22 and will to bore a hole and 22 is distinguished into two blocks, and wherein follow block 30 1 ends extend outward a pair of lug 32 respectively, and follow block 30 other ends extend to accommodation space.One end of elastic component 40 is fastened on the follow block 30 and the other end is resisted against metal shell 20.When 40 groups of follow block 30 and elastic components upright to the metal shell 20 after, 30 formation of follow block can be subjected to electronic cards or insert the elastic piece structure of member ejection.Also promptly, follow block 30 can flexibly form elastic piece structure towards the front and back swing when accommodation space is inserted pushing and pressing of member (not shown) or pull.
In an embodiment, button hole 24 utilizes proper method, and impact style is for example formed the button hole structure of protruding as its end face such as the arch bridge by metal shell 20.But the shape of button hole 24 is not limited to this, can supply follow block 30 collude if detain person provided thereon so long as can form a button portion, all is included in the scope of the present utility model.In addition, follow block 30 is arranged at the perforation 22 about middle positions on the metal shell 20, makes it respectively be 90 degree swings approximately towards front and back by the pendulum state.In addition, base plate 10 is replaceable to be a substrate (not shown), and utilizes welding or other suitable mode that metal shell 20 is fixed thereon.
The above-mentioned explanation that continues is the upright action of group of clearer description the utility model position limiting structure, and Fig. 3 A and Fig. 3 B found schematic diagram on the metal shell in order to explanation follow block and elastic component group upright action schematic diagram and elastic piece structure group respectively.At first, please refer to Fig. 3 A, as shown in the figure, elastic component 40 has a spring structure 42 and two free ends, and as end 44,45, wherein spring structure 42 circles are located at a side of close lug 32 on the follow block 30 and are utilized end 44 to be immobilizated on the follow block 30.Continue with reference to figure 3B, as shown in the figure, two lugs 32 pass button hole 24 on the metal shell 20 respectively so that follow block 30 flexibly is fixed on the metal shell 20 on the follow block 30.In addition, the end 45 of elastic component 40 is fastened on the metal shell 20, and the practice like this is to form an elastic piece structure that can be pushed against.In addition, this structure need not replaced follow block 30 or elastic component 40 that whole metal shell 20 can be changed damage easily when heavy industry, can effectively save the time of heavy industry.
Accept above-mentioned, please refer to Fig. 4 A, as shown in the figure, when an insertion member, as vacation card 50, when inserting in metal shell 20 and the base plate 10 formed accommodation spaces according to dotted line direction A1, follow block 30 can be subjected to false card 50 pushing and pressing and towards metal shell 20 swings, as the dotted line direction B1 in graphic, follow block 30 can be about 90 degree swings and form graphic shown in Fig. 4 A along direction B1 by vertical direction.But, this is only when false card 50 inserts metal shells 20, and a view that is presented in follow block 30 swing process is when follow block 30 falls in the hole 52 of false card 50, promptly present graphic shown in Fig. 4 B, follow block 30 can present about plumbness because of falling into hole 52.In this embodiment, on the metal shell 20, a plurality of holes 34 can be set, to increase the heat-sinking capability of card connector, in addition, the hole design also can alleviate mechanism's overall weight to meet frivolous trend.In addition, in this embodiment, also have multiple hole 52 on the false card 50, yet the hole 52 on the false card 50 is a prior art, so locate the no longer description more.
Continue, please refer to Fig. 4 C, when vacation card 50 was desired to be pulled out by accommodation space, as dotted line direction A2, follow block 30 can and allow false card 50 extract metal shells 20 smoothly out towards dotted line direction B2 swing.As shown in the figure, when vacation card 50 is extracted accommodation space out, follow block 30 is subjected to false card 50 pulls and swings towards the direction B2 shown in the figure, that is is about 90 degree swings from vertical direction towards metal shell 20, causes false card 50 can be easily to extract out and not influenced by follow block 30 from accommodation space.
In another embodiment, please refer to Fig. 4 D, Fig. 4 D is the local enlarged diagram of Fig. 4 B.As shown in the figure, this position limiting structure comprises that more a button pawl 34 is arranged on the follow block 30, and wherein the end 44 of elastic component 40 is immobilizated on the button pawl 34.In addition, more can be provided with one and collude shape fixed component 28 on metal shell 20, and outstanding metal shell 20 is in order to the other end of fixing elastic component 40, as end 45.More the person for convenient member pushing and pressing or the pull follow block 30 of inserting, can comprise that also a flanging 36 is formed at the end that follow block 30 stretches into accommodation space.But be understandable that the shape of follow block 30, big I are liked design according to the user, are not limited to illustrate among the figure.
According to above-mentioned, one of the utility model feature is that the elastic piece structure on the metal shell has removable advantage, or when the slot design of card connector has change, only need change the position or the shape of elastic piece structure, suitable elasticity on the processing procedure.Moreover metal shell of the present utility model is provided with a plurality of holes, not only can have good thermal diffusivity, more can alleviate mechanism's weight.
Comprehensively above-mentioned, the spacing members that utilization can be swung about 180 degree according to foreign object pushing and pressing or pull can solve the problem that can't extract when foreign object when card connector is pulled out.Again, when heavy industry, need not replace follow block and elastic component that whole metal shell can be changed damage easily, can effectively save the time of heavy industry.
Above-described embodiment only is explanation technological thought of the present utility model and characteristics; its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this; when can not with qualification protection range of the present utility model; promptly the equalization of doing according to the spirit that the utility model disclosed generally changes or modifies, and must be encompassed in the claim of the present utility model.
