Description

A kind of sim card connector

Technical field

This utility model relates to a kind of sim card connector.

Background technology

At present, mobile phone terminal is both provided with sim card connector, is used for SIM is installed. Terminal it is provided with in adapter.

Owing to different mobile phones are different to the size of SIM, the adapter of some mobile phone is before inserting SIM, it is necessary to SIM is cut little; And the adapter of some mobile phone needs to install bigger SIM, now, if to be continuing with cutting little after SIM, it is necessary to SIM is first assembled to inside cutting ferrule, at insertion adapter.

But, some user, when inserting cutting ferrule, forgets SIM to be assembled in cutting ferrule, so, when user wants the cutting ferrule extracting sky, the space in the middle of cutting ferrule can abut with the terminal of adapter, makes the movable end of terminal catch on the space in the middle of cutting ferrule thus hindering extracting of cutting ferrule. If user extracts cutting ferrule by force, then can damage terminal, cause mobile phone normally to use.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further elaborated:

As it is shown in figure 1, sim card connector 1 of the present utility model includes a base 11 and a fixing shell 12. When fixing shell 12 is installed on the pedestal 11, fixing space between shell 12 and base 11 forms SIM and the appearance card space of cutting ferrule 2 (shown in Fig. 4). Preferably, in the present embodiment, base 11 is identical with the shape of fixing shell 12, and with cutting ferrule 2 mating shapes of SIM or SIM, namely remove the rectangular shape at one of them angle.

Shown in Fig. 2, fixing shell 12 has a roof 121 and multiple sidewall, and sidewall has multiple buckle 122, and this buckle 122 extends from sidewall toward the inside of fixing shell 12. The roof 121 of fixing shell 12 is used for fixing SIM and cutting ferrule 2, and when fixing shell 12 is installed on the pedestal 11, buckle 122 abuts with the lower surface 110b of base 11, so that fixing formation between shell 12 and base 11 is fixed.

Base 11 has upper surface 110a and lower surface 110b, and is provided with accommodation portion 111 and flexible terminal 112 on base 11. Wherein, flexible terminal 112 is multiple, and multiple flexible terminals 112 form two rows. In the present embodiment, accommodation portion 111 is the shape of a through hole, can be up and down when making flexible terminal 112 contact with SIM. And in other embodiments, it can also be close to be formed that accommodation portion 111 is positioned at the position of base 11 lower surface 110b. Flexible terminal 112 is formed by conductive material, and has elasticity, and elastic deformation can occur. Additionally, flexible terminal 112 is positioned at the position of above-mentioned accommodation portion 111 correspondence, the shape in inverted " V ", contact site 1120 is the drift angle of inverted " V " shape, for the electrode contact with SIM. Preferably, flexible terminal 112 is metal clips. Certainly, flexible terminal 112 can also be formed by other elastic conducting materials.

As it is shown on figure 3, flexible terminal 112 has movable end 1121 and fixing end 1122, it is internal that fixing end 1122 utilizes the mode of in-mould injection or assembling to embed base 11. The side in the accommodation portion 111 of base 11 is additionally provided with space 113 and limiting unit 114, and flexible terminal 112 movable end 1121 embeds limiting unit 114 and is inserted in space 113. Preferably, flexible terminal 112 movable end 1121 be designed with limiting unit 114 up and down, namely movable end 1121 is between limiting unit 114, for the restraint end 1121 movement at above-below direction;And when elastic deformation occurs flexible terminal 112, the movable end 1121 of flexible terminal 112 can move in space 114 or slide. The movable end 1121 of flexible terminal 112 is lower than the upper surface 110b of base 11, and contact site 1120 is higher than the upper surface 110b of base. Additionally, flexible terminal is provided with welding foot, to realize firmly with welding circuit board and forming electric loop and being connected.

Limiting unit 114 can be totally enclosed type (i.e. the whole space 113 of upper-lower seal), it is also possible to be non-totally enclosed type. And in the present embodiment, preferably, limiting unit 114 is non-totally enclosed type, and its limiting unit 114 is one-body molded by plastic cement with base 11, the width of limiting unit is 0.1-0.5mm or other sizes, thus reducing frictional force when movable end 1121 moves in limiting unit or slides.

As shown in Figure 4, not installing the mounting portion 20 in the middle of the cutting ferrule 2 of SIM with SIM, mounting portion 20 is the shape of through hole. When user is inserted directly into adapter 1 because of faulty operation above-mentioned cutting ferrule 2, the contact site 1120 of flexible terminal 112 receives the pressure of cutting ferrule 2 at the beginning and moves down, and movable end 1121 moves forward a segment distance, and namely elastic deformation occurs flexible terminal 112. When the mounting portion 20 of cutting ferrule 2 is moved to the position of contact site 1120 correspondence of flexible terminal 112, contact site 1120 moves up, and movable end 1121 is moved rearwards by, and flexible terminal 112 returns to the original form. Owing to the movable end 1121 of flexible terminal 112 can move freely in space 114, therefore when user extracts cutting ferrule 2, contact site 1120 can also move down again, without hindering extracting of cutting ferrule 2, is more damaged from flexible terminal 112.

There is the sim card connector of said structure, even if user is in use by mistake inside empty cutting ferrule installation value adapter, owing to terminal having movable end, this movable end is lower than the upper surface of connector base, and can move freely front and back, therefore cause obstruction when cutting ferrule is extracted without to withdrawal process, be more damaged from terminal.

Embodiment described above, simply preferred embodiments of the present utility model, it is not limit practical range of the present utility model, therefore all equivalences done according to the structure described in this utility model claim, feature and principle change or modify, and all should be included in this utility model patent claim.
