BACKGROUND OF THE INVENTION

Field of the Invention

The present invention is related to a cover body sliding/locating structure of subscriber identity module (SIM) connector, and more particularly to a cover body of the SIM connector. Two sides of one end of the cover body are respectively bent to form two cartridge sections for pivotally connecting with the guide pins of the plastic main body. A projecting locating section is disposed on inner side of each cartridge section for locating the cover body in a position where the cover body can be turned up or latched with the plastic main body.

FIGS. 1,2and3show a current subscriber identity module (SIM) connector applied to mobile phone. The SIM connector includes a plastic main body91and a cover body92. Multiple terminals911are inlaid in the plastic main body91. One end of the cover body92is pivotally connected with the plastic main body91. A SIM card93can be placed in the plastic main body91. The cover body92can be turned to cover the SIM card93and clamp the SIM card93together with the plastic main body91. Accordingly, the SIM card93can be electrically connected with the terminals911.

Two sides of the cover body92are respectively formed with two slide slots921. Two guide pins912are formed on two sides of the plastic main body91and pivotally fitted in the slide slots921of the cover body92. Accordingly, the cover body92can be guided by the guide pins912to be stably transversely slid or turned upward. In use, such conventional structure has some shortcomings as follows:

1. As shown inFIG. 3, the cover body92has no locating structure in the slide slot921. Therefore, when transferred or taken by a mechanical arm and mounted on a mobile phone, due to shock, the cover body92is apt to transverse slide and unlatch from the plastic main body91and automatically pivot up. This will affect the installation of the SIM connector on the mobile phone.

2. Referring toFIG. 3, when a user turns up the cover body92, the cover body92will simultaneously slide forward F along the guide pins912(as shown by the phantom line). When the user places in the SIM card to close the cover body92, since the cover body92has been displaced, the user needs to pull the cover body92rearward (in the direction of arrow B) and then close the cover body92to cover the SIM card. This is inconvenient to the user.

3. The cover body92has a longitudinally extending insertion plate922, which is latched under a locating block913of the plastic main body91. The insertion plate922is an elongated plate body which is apt to be bent and deformed.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide a cover body sliding/locating structure of SIM connector in which by means of the locating sections of the cartridge sections, the cover body can be temporarily located and prevented from sliding during turning up operation. Accordingly, when a user successively closes the cover body, the cover body can be directly downward closed to cover the plastic main body. This facilitates use and operation of the SIM connector.

It is a further object of the present invention to provide the above cover body sliding/locating structure of SIM connector in which when the cover body is closed to latch on the plastic main body, the locating sections of the cartridge section of the cover body will stop the outer edge of the plastic main body and prevent the cover body from freely sliding on the plastic main body. Therefore, during installation of the SIM connector, the cover body will not displace or automatically pivot outward. This facilitates installation of the SIM connector on a mobile phone.

It is still a further object of the present invention to provide the above cover body sliding/locating structure of SIM connector in which the lateral edges of the board body of the cover body are directly downward bent to form the L-shaped hook sections for hooking with the plastic main body. The L-shaped hook sections are not elongated sections so that when the cover body is slid to latch with the plastic main body, the L-shaped hook sections are not apt to deform. Therefore, the using life of the SIM connector is prolonged.

According to the above objects, the cover body sliding/locating structure of SIM connector includes: a plastic main body formed with multiple terminal cavities in which multiple terminals are respectively inlaid, two sides of one end of the plastic main body being respectively formed with two guide pins; and a cover body. Two sides of one end of the cover body are respectively bent to form two cartridge sections. A first end of the cartridge section is formed with a slide entrance in which the guide pin is pivotally fitted. At least one projecting locating section is disposed on inner side of the cartridge section for locating the cover body in a position where the cover body can be turned up or latched with the plastic main body. At least one projecting stopper board is formed at an opening of a second end of the cartridge section for stopping the guide pin. An L-shaped hook section downward projects from each lateral edge of the cover body for correspondingly hooking and latching with a locating block of the plastic main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer toFIGS. 4 to 12. The present invention is related to a cover body sliding/locating structure of SIM connector. The SIM connector includes a plastic main body1and a cover body3. Two sides of the cover body3are respectively formed with two cartridge sections32. Two sides of a second end of the plastic main body1are respectively formed with two guide pins13. The cartridge sections32are pivotally fitted on the guide pins13. The inner side of each cartridge section32is formed with a projecting locating section33. The projecting locating section33serves to locate the cover body3in a position where the cover body3is latched with the plastic main body1or the cover body3can be turned upward.

Referring toFIGS. 4 and 5, the plastic main body1includes a substrate11. A receiving dent12is defined on the substrate11. A SIM card4can be snugly accommodated in the receiving dent12. The substrate11is formed with multiple terminal cavities111in which multiple terminals1aare respectively inlaid. Two sides of a second end of the plastic main body1are respectively formed with two guide pins13. At least one locating block14projects from a lateral edge of the plastic main body1. A bottom section of the locating block14is formed with a latch dent141.

Referring toFIG. 4, the cover body3is made of metal material. The cover body3includes board body31and two cartridge sections32integrally connected with two sides of a second end of the board body31. Each cartridge section32has a sideboard321. A top end of the sideboard321is integrally connected with a lateral edge of the board body31. A bottom end of the sideboard321is inward bent to form a bottom board322. The bottom board322and the board body31define therebetween a receiving space30. The guide pin13of the plastic main body1is pivotally fitted in the receiving space30. A first end of the cartridge section32is formed with a slide entrance323. A projecting stopper board324is formed at the opening of a second end of the cartridge section32for abutting against outer side of the guide pin13to stop the guide pin13and prevent the cover body3from further displacing. At least one projecting locating section33slightly projects from inner side of the cartridge section32near the second end thereof. The locating section33serves to slide with the cover body3to stop a lateral side of the guide pin13, whereby the cover body3is located in a position where the cover body3is latched with the plastic main body1or the cover body3can be turned upward. At least one L-shaped hook section34downward projects from an edge of the board body31for correspondingly hooking and latching in the latch dent141of the bottom of the locating block14of the plastic main body1.

Referring toFIGS. 4 and 12, the present invention further includes at least one grounding plate2made of metal board by integral punching. A first end of the grounding plate2is formed as an insertion end21which is tightly inserted in an insertion slit15of one side of the plastic main body1. A bottom section221of a second end22of the grounding plate2always electrically contacts with a grounding circuit of a circuit board5. A top section of the second end22is formed with a first adjoining section222for connecting on the cover body3to ground the cover body3and shield the SIM card from external static and magnetic wave. The second end22of the grounding plate2is formed with a substantially C-shaped cross-section or the like. This is not limited.

The cover body3has at least one second adjoining section35projecting from a lateral edge of the board body31of the cover body3. When the cover body3is latched on the plastic main body1, the second adjoining section35of the cover body3contacts with the first adjoining section222of the grounding plate2to electrically connect with the grounding circuit of the circuit board5.

Referring toFIGS. 4 to 9, when assembled, the guide pins13of two sides of the plastic main body1are slid and fitted into the slide entrances323of the first ends of the cartridge sections32of the cover body3. At this time, the cover body3can be freely pivotally rotated about the guide pins13on the plastic main body1. Also, the cover body3can be guided by the guide pins13to stably transversely slide. Referring toFIGS. 5 to 7, in use of the present invention, the cover body3is first pulled toward the first end of the SIM connector to unlatch the L-shaped hook section34from the plastic main body1. At this time, the guide pins13of the plastic main body1are relatively moved to a position between the locating sections33and the stopper boards324of the cartridge sections32of the cover body3. Under such circumstance, the user can freely turn up the cover body3and place in a SIM card4. In the turning up operation of the cover body3, the guide pins13of the plastic main body1are restricted between the locating sections33and the stopper boards324of the cover body3. Therefore, the cover body3is prevented from sliding. Accordingly, when the user successively closes the cover body3as shown inFIGS. 8 and 9, the cover body3is not slid so that the user can directly downward close the cover body3. This facilitates use and operation of the SIM connector.

Referring toFIGS. 10 to 12, when the cover body3is slid and pushed in the direction R, the guide pins13of two sides of the plastic main body1will relatively slide out of the locating sections33of the cover body3and move to outer sides of the first ends of the locating sections33. The L-shaped hook sections34of the cover body3will correspondingly hook and latch in the latch dents141of the bottoms of the locating blocks14of the plastic main body1. The locating sections33stop the second ends of the guide pins13of the plastic main body1. Therefore, when an ordinary external force is applied to the cover body3(for example, the shock during transfer or operation of a mechanical arm for mounting the SIM connector on a mobile phone), the cover body3will not displace in the direction R1. Accordingly, the cover body3can be firmly latched on the plastic main body1without pivoting up from the plastic main body1in the transfer or installation. Therefore, the installation is facilitated.

The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
