1. Field of the Invention
The present invention relates to an electrical connector, and more particular to an electrical connector for a sheet-like connection member such as a flexible printed circuit (FPC), a flexible flat cable and so forth.
2. Description of Related Art
U.S. Pat. No. 5,816,845 discloses a conventional connector adapted for connecting a flexible printed circuit (FPC). The connector comprises a insulating housing having an insertion cavity into which the FPC is adapted to be inserted and a pair of guiding grooves respectively at two ends thereof. A plurality of metal terminals is mounted on the housing. A projection is formed on each guiding grooves adjacent to an insertion port of the cavity and a sliding member with two arms at two opposite ends thereof is pushed into the guide groove across the projection.
However, when assembling the sliding member into the cavity, the arms made of plastic material, which get across the projection into the guiding grooves, may be broken. Furthermore, after the connector is mounted on a printed circuit board (PCB), it is difficult to replace a new sliding member if the sliding member is damaged during using. Therefore, a new design is required.
An object of the present invention is to provide an electrical connector with easily replacement of a slider.
In order to achieve above-mentioned objects, an electrical connector for a sheet-like connection member in accordance with the present invention comprises an insulating housing including a long wall, a short wall and a pair of endwalls beside said two walls, and said four walls forming a receiving cavity. A first and a second retaining wall parallel to the long wall and the short wall are formed at each side of the endwalls. A groove is formed by said two retaining walls with a first latching portion adjacent to the first retaining wall, and an entry is defined between the first latching portion and the second retaining wall. A slider comprises a tongue plate insertable into the receiving cavity and a pair of latching arms. The latching arms are assembled into the groove from the entry and then slide in the groove.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail.

Each conductive terminal 2 comprises a base section 21, a pair of solder portion 22 extending out from two opposite ends of the base section 21 to be soldered on a PCB (not shown), a fixing arm 23 extending upwards from the base section 21 to be retained in terminal groove 11 defined by the back wall 102, a first resilient arm 24 extending substantially parallel to the fixing arm 23, and a second resilient arm 25 branching from a root portion of the fixing arm 23 and extending upwards parallel to the first resilient arm 24. Both of the resilient arms 24, 25 are received in the terminal grooves 11 together defined by the front wall 101, and the first resilient arm 24 is longer than the fixing arm 23, i.e. nearer to an insertion open of the receiving cavity 10, as best shown in
The connector 100 further has a pair of retaining terminals 4. The structure of the retaining terminal 4 is similar to the conductive terminal 2, but without a second resilient arm.

Assembling the slider 3 into the housing 1 is in the same way. First put the grasping portion 331 of the latching arm 33 under the first latching portion 13, wherein the distal end 333 is blocked by the top of the interface. Then an enlarged force is exerted on the slider 3 to make the distal end 333 surpass the interface “T”. Thus the slider 3 is assembled into the housing 1.
The slider 3 of the invention is easily assembly into and divorced from the housing 1 without damaging the latching arms 33, therefore the slider 3 is easily to be replaced if it is damaged.
The present invention is not limited to the electrical connector 100 mentioned above. This disclosure is illustrative only, changes may be made in detail, especially in matter of shapes, size, and arrangement of parts within the principles of the invention. For example, the distance “T” can be changed from 0.1 mm to 0.3 mm.
