1. Field of the Invention
The present invention relates to an electrical connector for receiving a card-like component therein.
2. Description of the Related Art
Issued U.S. Pat. No. 7,270,559 disclose a conventional electrical connector adapted for receiving a card. The connector has a metal cover rotatably assembled on one end of the base with conductive terminals. The cover rotate downwards to the base and move to the pivot position along the horizontal direction to lack the cover with the base after the card is placed in the base or the cover. It is well known that it needs three steps to complete assembling of the card to the connector. Sometimes, said structure is believed complex.
In view of the above, a new electrical connector that overcomes the above-mentioned disadvantages is desired.
Accordingly, an object of the present invention is to provide an electrical connector which is facility for assembling of a card therein.
To fulfill the above-mentioned object, an electrical connector for receiving a card comprises an insulating housing, a plurality of terminals and a metal frame attached to the insulating housing. The insulating housing comprises a base having a terminal-location portion, a pair of sidewalls extending a first direction and a rear wall adjacent to the terminal-location portion. The terminals are arranged in the terminal-location portion along a second direction perpendicular to the first direction. The metal frame is attached to the insulating housing and comprises a base portion located above the terminal-location portion to define a receiving slot between the terminal-location portion and the base portion for receiving a mating end of the card, the base portion is not beyond the terminal-location portion in the first direction and the receiving. The metal frame further comprises a pair of locking portions adapted for pressing against a top face of the card to lock the card in the insulating housing and moving outwards in the second direction to release the card.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawings to describe the present invention in detail.

Referring to
The metal fame 3 is formed by stamping and bending a metal plate, which is construed from a base portion 12 and a pair of side arms 10 extending from two ends of the base portion 12. Each side arm 10 includes two parallel vertical portions 130, 133 and a horizontal portion 131 connecting with said vertical portions. After the metal frame slides to the housing along the first direction, the base wall 12 cover on the rear wall 23 and portions over the terminal-location portion 201 to deform a receiving slot 301. The width of base portion in the first direction is dimensioned to not exceed the terminal-location portion 201 in the first direction so as to be suitable for the insertion of the card 90, in a preferred embodiment, the base portion 12 do not exceed the rear row of the terminals 3A. The outer vertical portions 130 abut against the outer faces of the side walls 21 and the horizontal portions 131 is on the top face of the side walls 21, and two retaining tabs 134 bending inwards from the outer vertical portion 130 slide into a groove 211 on the insertion of the outer face and bottom face of the side walls of the housing so that the metal frame 1 is retained on the housing. The projections 230 on the top of the rear wall are used for protecting the metal frame 1. A soldering portion 135 bends outwards from the outer vertical portion 130.
The base wall 20 projects a locking post 24 near to a front of the notch 202, which is adjacent to the side arm 21. A slit slot (not labeled) is construed at the intersection of each side wall 21 and the base wall 20 and the middle portion of each side wall 21 is recessed inward from the slit slot thereof to define a moving recess 210. The sliding slot runs through a front edge of the housing, i.e., the post 24 separates from the side arm by the slot 25. The inner vertical portions 133 slide into the slots and can move outwards in the second direction by urging (with spring elasticity). A handing portion 15 extend upright from the top edge of the inner vertical portion 133 and then bending down at the outside. Each handing portion 15 has a locking portion 16 formed in the middle thereof which extend downwards freely with an inwards-slant tip. An abutting portion 17 extends forwards and inwards from the front bottom edge of the inner vertical portion 15, which abuts against a shadow recess 240 defined on the post 24 so that the metal frame 1 can be prevented from separating from the side wall 21 in the first direction. The rear ends 1331 of the inner vertical portion 133 are pressed against the sidewall to provide a pivot point when the hander portions 15 are urged to shift outwards in the second direction.
Referring to
The card is released from the housing by a manner that the handle portions 16 are urged to shift outwards and the card is detached from the locking portions.
It is to be understood, however, that 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, and changes may be made in detail, 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.
