Connector

Abstract

A connector holds and is connected electrically with a memory card such as a subscriber identity module (SIM) card and has an insulative housing, a plurality of terminals and a cover. The insulative housing has two sidewalls and a pair of holders. The holders are formed respectively on the sidewalls, and each holder has a lateral segment and a limiting segment. The lateral segment is formed on a corresponding sidewall. The limiting segment protrudes from the lateral segment to define a gap between the limiting segment and the corresponding sidewall. The terminals are mounted in the insulative housing. The cover is connected pivotally with the insulative housing and has a pair of mounting legs. Each mounting leg is connected with a corresponding sidewall and has a limiting tab selectively extending into a corresponding gap to prevent the mounting leg from moving transversely to further prevent the cover from detaching.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 2 and 3, a connector (100) in accordance with the present invention holds and is connected electrically with a memory card such as a subscriber identity module (SIM) card and comprises an insulative housing (10), a plurality of terminals (40) and a cover (30).

The insulative housing (10) has a front end, a rear end, a bottom (101), two opposite sidewalls (102), two rear walls (104), a recess (106), a pair of pivot holes (103), a plurality of mounting slots (107) and a pair of holders (105) and may further have a pair of mounting notches (108).

The sidewalls (102) are formed on and protrude up from the bottom (101).

The rear walls (104) are formed on and protrude up from the bottom (101) at the rear end adjacent respectively to the sidewalls (102).

The recess (106) is defined in the insulative housing (10) and may accommodate a SIM card.

The pivot holes (103) are defined respectively in the sidewalls (102) near the rear end.

The mounting slots (107) are defined in the bottom (101).

The holders (105) are L-shaped, correspond respectively to and are formed respectively on the sidewalls (102) adjacent to the rear end, and each holder (105) has a lateral segment (1051) and a limiting segment (1052). The lateral segment (1051) is formed on and protrudes transversely out from a corresponding sidewall (102). The limiting segment (1052) is connected with and protrudes perpendicularly from the lateral segment (1051) and is separated from the corresponding sidewall (102) to define a gap between the limiting segment (1052) and the corresponding sidewall (102).

The mounting notches (108) are defined respectively in the sidewalls (102), and each mounting notch (108) has an inner surface.

The terminals (40) are conductive and are mounted respectively in the mounting slots (107).

The cover (30) is connected pivotally with the insulative housing (10) at the rear end and has a body (301), two opposite sides and two mounting legs (303) and may further have a pair of retaining tracks (309) and a pair of clamps (302).

The body (301) has a proximal end and a distal end.

The mounting legs (303) are formed respectively on and protrude respectively out from the sides at the proximal end of the body (301). The mounting legs (303) correspond respectively to the sidewalls (102) and the holders (105) and are pivotally connected respectively with the sidewalls (102) of the insulative housing (10) at the rear end. Each mounting leg (303) has an outer edge, a pivot boss (305) and a limiting tab (307). The pivot boss (305) is formed transversely on the mounting leg (303) by punching the mounting leg (303) and is mounted in the pivot hole (103) in a corresponding sidewall (102) of the insulative housing (10). The limiting tab (307) may be curved, is formed on and protrudes out from the outer edge of the mounting leg (303) and selectively extends into the gap between the limiting segment (1052) of a corresponding holder (105) and the corresponding sidewall (102) to abut the limiting segment (1052). When the cover (30) opens on the insulative housing (10), the limiting tab (307) extends into the gap and abuts the limiting segment (1052). The limiting segment (1052) presses against the limiting tab (307) and keeps the mounting leg (303) from bending and moving transversely relative to the insulative housing (10) to further prevent the pivot boss (305) from escaping from the pivot hole (103). With the limiting holders (105) and the limiting tabs (307), the cover (30) will not separate inadvertently from the insulative housing (10).

The retaining tracks (309) are formed respectively on and protrude respectively from the sides of the cover (30) and may slidably hold a SIM card.

The clamps (302) are formed respectively on and protrude respectively out from the sides of the cover (30) and are selectively engaged with the mounting notches (108) in the insulative housing (10) tightly to clamp the insulative housing (10) and prevent the cover (30) from opening inadvertently.

The holders (105) and the limiting tabs (307) prevent the pivot bosses (305) on the mounting legs (303) of the cover (30) from escaping from the pivot holes (103) in the insulative housing (10). Therefore, the cover (30) firmly is connected with the insulative housing (10) and will not detach unintentionally.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
