Abstract

The utility model provides an SIM card clamping device, which comprises a clamping seat and a spring plate, wherein, the clamping seat is provided with a sinking part which is used for accommodating the SIM card; and the spring plate is formed by extending inside the sinking part. As the spring plate of the SIM card fixing device is arranged in the sinking part, not only the effect of limiting the SIM card is achieved, but also no space outside the clamping seat is occupied. Furthermore, the interference generated by the spring plate and other elements which are arranged on the outer side of the clamping seat is avoided, and the reliability of the device is ensured.

Description

A kind of SIM card holding unit

Technical field

The utility model relates to a kind of SIM card (Subscriber Identity Module card, Subscriber Identity Module) holding unit, particularly a kind of SIM card holding unit that is used for mobile phone.

Background technology

Along with developing rapidly of mobile communication cause, mobile phone has become the more and more consumer's routine works and the indispensable instrument of living.The SIM card of mobile phone has functions such as record individual user number and address list, by changing SIM card, a mobile phone can use for a plurality of users, therefore, the fixed form of SIM card is just quite important, if can't be firmly fixing SIM card, mobile phone is easy to take place situation such as deadlock and can not normally uses.

SIM card normally is limited in the deck by shell fragment, at present on the market the SIM card holding unit of most mobile phones as shown in Figure 1, its shell fragment 1 extends in the deck 2 export-oriented decks 2 and forms, promptly shell fragment 1 is to be arranged at SIM card outside occupying.During because of the mobile phone project organization, the space of its housing is limited, once the outer housing of SIM card need be hollowed out, just shell fragment 1 can't be set, in case perhaps in the housing electronic component is arranged, shell fragment 1 can be withstood by these elements and lose elasticity, thereby causes SIM card to be difficult for entering and withdraw from deck 2.

The utility model content

The SIM card holding unit that technical problem to be solved in the utility model is to provide a kind of compact conformation, takes up room less.

The utility model is achieved in that a kind of SIM card holding unit, comprises deck and shell fragment, and described deck has the depressed part in order to ccontaining SIM card, and described shell fragment extends in depressed part and forms.

Compared with prior art, the shell fragment in the above-mentioned SIM card holding unit is positioned at depressed part, both can reach the effect of restriction SIM card, the space that vacant again deck is outer.In addition, also can avoid shell fragment and other elements that are positioned at the deck outside to interfere, guarantee the reliability of device.

Description of drawings

Fig. 1 is the schematic perspective view of SIM card holding unit in the prior art.

The schematic perspective view of the SIM card holding unit of Fig. 2 the utility model one embodiment.

Fig. 3 is used for fixing the schematic perspective view of SIM card for the SIM card holding unit among Fig. 2.

Embodiment

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Fig. 2 and the SIM card holding unit that Figure 3 shows that the utility model one embodiment.This SIM card holding unit comprises deck 10 and shell fragment 20.

Deck 10 is located on the housing 30 of products such as mobile phone, in the present embodiment, is provided with two decks that are set up in parallel 10, in order to settle two SIM card 40, is appreciated that ground, a deck 10 also can only be set, in order to settle a SIM card 40 on housing 30.

This deck 10 has depressed part 11 and reaches across the press strip above depressed part 11 12.Described depressed part 11 is in order to ccontaining SIM card 40, and it has the suitable accommodation space of geomery and SIM card 40.This depressed part 11 has the hypotenuse 112 and the skew wall 113 of flat bottom surface 111, bottom surface 111 inclinations relatively.In the present embodiment, bottom surface 111, hypotenuse 112 are obliquely installed skew wall 113 relatively simultaneously.

111 are provided with a rectangular aperture 114 in the bottom surface, to expose connector insulating body 50 on the printed circuit board (PCB) that is installed in housing 30 inside and terminal 51 mounted thereto.This hypotenuse 112 is positioned at an end of bottom surface 111, and hypotenuse 112 is that 111 end edge obliquely from the bottom surface, stretching out forms.A corner edge of 111 obliquely from the bottom surface, stretching out forms for skew wall 113, and it can cooperate with the oblique angle 41 of SIM card 40, both can avoid wrong plug SIM card 40, can play the effect of guiding again.

Shell fragment 20 is arranged in the depressed part 11, and it extends in depressed part 11 and forms.Shell fragment 20 roughly is " U " by one, the groove 115 of shape is separated with bottom surface 111 and hypotenuse 112.This shell fragment 20 is included in extension 21 and the pressure section 22 that extends in the bottom surface 11.111 inboards extend out to concordant with bottom surface 111 end edge this extension 21 from the bottom surface.This pressure section 22 from the end of extension 21 obliquely, stretching out forms, and pressure section 22 is positioned at depressed part 11, and closes on hypotenuse 112.The opening direction of groove 115 is towards the inside of depressed part 11, and around shell fragment 20 settings, the part of groove 115 is positioned on the bottom surface 111, and is positioned at the relative both sides of extension 21, and the remainder of groove 115 is positioned on the hypotenuse 112, and around pressure section 22.

When SIM card 40 is installed, SIM card 40 is tilted to be positioned over the side that depressed part 11 has hypotenuse 112, and apply external force, SIM card 40 is slipped into below the card article 12 gradually along SIM card 40 vergence directions; Continue to apply external force, the front end of SIM card 40 slips in the depressed part 11 under the guiding of skew wall 113 and hypotenuse 112 gradually, in this process, the front end of SIM card 40 applies an acting force towards depressed part 11 outsides to pressure section 22, makes pressure section 22 produce certain deformation on the direction in depressed part 11 outsides.After in SIM card 40 slips into depressed part 11 fully, pressure section 22 resiliences and the front end of SIM card 40 is applied an acting force, thus make SIM card 40 stable being located in the depressed part 11.

When needs take off SIM card 40, the front end that pushing and pressing SIM card 40 makes SIM card 40 applies one towards the acting force in depressed part 11 outsides and make pressure section 22 produce certain deformation on the direction in depressed part 11 outsides to pressure section 22, so can take out SIM card 40.

In sum, the shell fragment 20 of above-mentioned SIM card holding unit is positioned at the depressed part 11 of deck 10, both can reach the effect of restriction SIM card 40, the space outside the vacant again deck 10.In addition,,, can avoid and other elements of being positioned at deck 10 outsides interfere, can guarantee the reliability of device so shell fragment 20 is located in the depressed part 11 because the space between the general printed circuit board (PCB) with housing 30 inside in the shared position of deck 10 is narrow and small.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
