Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
See Fig. 1 and Fig. 2, the specific embodiment of the distortion-free card connector of the utility model is three select two card connectors, comprise: housing 1, terminal 2 and plastic body 3, wherein, housing 1 and terminal 2 shaping by metallic conduction sheet material integrated punching, terminal 2 is preferably embedded with the mode and plastic body 3 of injecting insert molding (insertmolding) and is integrated and is formed a terminal assembly 4.Certainly, the mode that terminal 2 and plastic body 3 also can be assembled is embedded and is integrated and forms this terminal assembly 4.When leaving insert port 7, NanoSIM card in front end after housing 1 with terminal assembly 4 assembly and/or namely MicroSD card inserts from insert port 7.In order to meet the function that three select two, terminal 2 is arranged with from front to back three groups of conducting terminals, be positioned at middle conducting end subgroup and transmit different signals from the conducting end subgroup at two ends, on the whole this and prior art are similar, do not repeat in the utility model.
Between the first side wall (in Fig. 7 left side wall) and the first side wall (in Fig. 7 left side wall) of housing 1 of terminal 2, leave sliding space, in sliding space, trip mechanism is installed.Trip mechanism specifically comprises: propulsion arm 5 and action bars 6, wherein, propulsion arm 5 be installed on terminal assembly 4 away from the rear end of insert port 7 and one end abut with the link 61 of action bars 6, action bars 6 is arranged in sliding space and operating side 62 and stretches out from sliding space, and the operating side 62 of action bars 6 is spoon shape structure.Pull the operating side 62 of spoonful shape the NanoSIM card in card connector and/or MicroSD card can be ejected from insert port 7, move back card (two kinds of location statuss of operating side 62 have been shown in Fig. 1) easy to operate.
In order to fast and reliable housing 1 is fitted in terminal assembly 4 together with, housing 1 and terminal 2 are provided with multipair connection fastening structure each other, and this fastening structure is coordinated by the multiple engaging lugs 8 be divided on the inside panel (adjacent with the first side wall of housing 1 and establish) of housing 1 and the second sidewall and the multiple link slots 9 be divided into accordingly on the first side wall of terminal 2 and the second sidewall and forms.In the present embodiment, fastening structure is 5 right, as shown in Figure 3 and Figure 7, engaging lug 8 is divided into: before, during and after housing 1 second sidewall before three positions and housing 1 inside panel, in two positions, link slot 9 is arranged at the relevant position of terminal 2 second sidewall and the first side wall accordingly, by rationally setting up separately fastening structure, can effectively ensure assembly reliability.In addition, as shown in Figure 5, the bottom-up sectional area of engaging lug 8 increases gradually, and such structure is conducive to fastening operation, and can prevent fastening rear engaging lug 8 and skid off from link slot 9.
The particularly important innovation of the utility model is the distortion effectively preventing terminal 2 and housing 1, see Fig. 3 to Fig. 8, correspondingly on second sidewall, the first side wall of the second sidewall of housing 1, inside panel and terminal 2 be formed with a multipair anti-structure changes, often pair of anti-structure changes is formed by inner panel spacing each other and outside plate, one in inner panel and outside plate is arranged on housing 1, then another must be arranged on terminal 2.It should be noted that, so-called " inner panel ", when referring to terminal 2 and housing 1 assembly, be positioned at that piece of plate body of inner side, obviously, " outside plate " just refers to that piece of plate body being positioned at outside.And, housing 1 at least has an inner panel and an outside plate, that is, terminal 2 must at least have an outside plate and an inner panel, this makes it possible to play the effect preventing outer distortion and prevent interior distortion simultaneously, utilize this anti-structure changes to ensure that housing 1 and terminal 2 realize restriction mutually when assembly, prevent distortion.
In the present embodiment, the Position Design of inner panel and outside plate is very reasonable.Particularly, as shown in Figure 3 and Figure 4, three link slot 9 place side plates on terminal 2 second sidewall are the first outside plate 10, first outside plate 10 is also provided with between anterior link slot 9 and middle part link slot 9 place outside plate, be two the first inner panels 11 between three outside plates forward of middle part, these three the first outside plates 10 and two the first inner panels 11 are overall continual structure; Correspondence position on housing 1 second sidewall is provided with four the second inner panels 13 independent of each other and two the second outside plates 12, and engaging lug 8 is positioned at wherein on three the second inner panels 13.In order to fasten guiding terminal assembly 4, in four the second inner panels 13 of housing 1 second sidewall, except except the anterior inner panel of insert port 7, another three the second inner panels 13 have all been bent to form the first fastening guidance part 19 to the direction near housing 1 the first side wall.
As shown in Figure 7 and Figure 8, two link slot 9 place side plates on terminal 2 the first side wall are the 3rd outside plate 14, two the 3rd outside plates 14 and form overall continual structure by one the 3rd inner panel 15; Correspondence position on housing 1 inside panel is provided with independent of each other two the 4th inner panels 17 and the 4th outside plate 16, and engaging lug 8 is positioned on two the 4th inner panels 17.In order to fasten guiding housing 1,3rd inner panel 15 of terminal 2 the first side wall is bent to form the second fastening guidance part 20 to the direction arc near its second sidewall, meanwhile, the 3rd outside plate 14 in the middle part of terminal 2 the first side wall is bent to form the 3rd to the direction arc away from the second sidewall and fastens guidance part 21.
So, first outside plate 10 and the second inner panel 13, first inner panel 11 and the second outside plate 12, the 3rd outside plate 14 and the 4th inner panel 17, the 3rd inner panel 15 are formed respectively with the 4th outside plate 16 and coordinate, housing 1 and terminal 2 are realized spacing mutually, effectively can prevent outer and interior distortion of housing 1, terminal 2.
As further improvement of the utility model, near the second inner panel 13 and the 4th inner panel 17 all inwardly downward-extension formation welding foot 18 of housing 1 front end insert port 7, terminal 2 is formed with the through slot 22 passed for welding foot 18, welding foot 18 arrives pcb board to be welded after through slot 22, realizes the bonding strength between product and pcb board while effectively can guaranteeing the mechanical strength of product own.
To sum up, card connector structure of the present utility model is ingenious, assembly convenient, together with housing 1 can firmly be fitted in terminal 2 by the fastening structure consisted of engaging lug 8 and link slot 9, the anti-structure changes of recycling can ensure that housing 1 and terminal 2 realize restriction mutually when assembly well, thus effectively prevents distortion.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection range of the present utility model.
