Description

SIM Card Connector

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a SIM card connector used for a mobile communication terminal and the like, which enables an electrical connection between a SIM card and a printed circuit board, and more particularly, to improve the mountability of a SIM card connector soldered to a printed circuit board. The present invention relates to a SIM card connector.

A SIM (Card Subscriber Identity Module) card is provided to a device such as a mobile communication terminal in the form of a removable smart card, that is, an IC card. In general, a SIM card stores a key used to identify a user and needs to be connected to an electronic circuit such as a printed circuit board provided to the mobile communication terminal in order to be inserted into the mobile communication terminal to function.

In general, the SIM card connector is composed of a plurality of contact terminals electrically contacting the SIM card, a housing on which the contact terminals are mounted, and a shell covering the housing.

According to the prior art, there is a problem in that the SIM card connector cannot be mounted with sufficient strength when soldering to the printed circuit board.

SUMMARY OF THE INVENTION An object of the present invention is to provide a SIM card connector which can solve the problems of the prior art as described above and can increase the mountability when soldering a SIM card connector to a printed circuit board.

According to the present invention, a SIM card connector used in a mobile communication terminal to enable electrical connection between a SIM card and a printed circuit board of the terminal,

Contact terminals 21a and 21b electrically contacting the SIM card,

A housing 20 connected to the printed circuit board and mounted with contact terminals 21a and 21b;

A shell 10 is coupled to the housing 20 to cover the upper portion 201 of the housing 20.

The shell 10 has an upper surface facing the upper portion of the housing 20, a side surface extending downward from the upper surface and facing the side wall of the housing 20, and extending inward from the side surface. The lower surface 13a, 13b which is arrange | positioned so that it may face the bottom part 203 of 20 and is soldered to the said printed circuit board is included, and the said lower surface 13a, 13b is formed with the hole.

According to the structure of this invention, when soldering, solder flows into the hole formed in the lower surface 13a, 13b of the shell 10, and solderability is increased, and a SIM connector is firmly attached to a printed circuit board. A fixed effect is provided.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is an exploded perspective view of a SIM card connector according to the present invention.

As shown in FIG. 1, the SIM card connector according to the present invention includes a shell 10, a housing 20, and a plurality of contact terminals 21a and 21b adapted to be mounted to the housing 20. do.

The shell 10 is from the upper surface 11 on the side facing the upper surface 11 and the first side surfaces 15a and 15a 'extending downward from the upper surface 11 and the first side surfaces 15a and 15a'. A second side surface 15b extending downward, a first lower surface 13a extending vertically inwardly from the first side surfaces 15a and 15a ', and an agent extending vertically inwardly from the second side surface 15b; It includes two lower surfaces 13b. And the hole 150 is formed in the 1st lower surface 13a and the 2nd lower surface 13b. When soldering the lower side of the SIM card connector in the coupled state to the printed circuit board, such as a mobile communication terminal, by soldering, as shown in FIG. 3, the solder also flows into the lower side of the shell 10. ), The shell 10 can be more firmly fixed to the printed circuit board, resulting in the effect of more firmly fixing the entire SIM card connector to the printed circuit board.

The housing 20 includes a first mounting groove 29 including an upper portion 201, a first side portion 25a and a second side portion 25b, on which contact terminals 21a are mounted in front, At the rear, a second mounting groove 31 is formed in which the contact terminal 21b is mounted. A locking protrusion 27a is formed at the first side portion 25a. When the shell 10 is engaged with the housing 20, the locking protrusion 27a is caught by the first side portion 15a 'of the shell 10 so that the shell is caught. Make sure that (10) is not separated from the housing (20). Although not shown as the opposite side, the engaging projection is also formed on the second side portion 25b and is caught by the second side surface 15b of the shell 10 so as not to be separated from the housing 20 of the shell 10.

The shape of the contact terminal 21a and the contact terminal 21b is the same. The shape of the contact terminal 21a is shown in detail in FIG.

The contact terminal 21a includes a first portion 210 which is brought into direct electrical contact with the SIM card when the SIM card (not shown) is inserted in the A direction, and a second portion which is to be mounted on the printed circuit board ( 230, wherein the first portion 210 and the second portion 230 are staggered with respect to each other. The staggered shape is shown in detail in FIG. 4.

In this way, when the first portion 210 and the second portion 230 are staggered from each other, even if the first portion 210 is deformed downward when the SIM card is inserted, the first portion 210 may be the second portion ( It does not collide with 230, and therefore does not collide with the portion of the printed circuit board on which the second portion 230 is mounted.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is defined by the claims below, and should not be construed as being limited to the embodiments and / or accompanying drawings described above. do. And it should be clearly understood that improvements, changes and / or modifications of the invention described in the claims are included in the scope of the invention.
