ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical connectors, and particularly to an arrangement for securing an electrical connector to a printed circuit board.
2. Description of the Prior Art
U.S. Pat. Nos. 5,228,870 and 4,907,987 disclose a connector to circuit board securing arrangement including a planar barbed holding device installed within a recess of a mounting portion on a connector for subsequent insertion into an appropriately aligned cavity in a printed circuit board. The recess of the connector is open to a lower mounting face of the connector, so the holding device needs to be first inserted into the recess of the connector from the lower side of the connector, and then engaged with the cavity of the printed circuit board. The assembly procedure is complicated and the placement of the holding device is difficult, thereby decreasing production efficiency. The connection of the holding device with the electrical connector and the printed circuit board is apt tQ loosen, thereby reducing the stability of the mechanical connection between the electrical connector and the printed circuit board.
Therefore, an improved arrangement is desired to overcome the disadvantages of the prior art.
SUMMARY OF THE INVENTION
A first object of the present invention is to provide a connector to circuit board securing arrangement which is easier to assemble; and
A second object of the present invention is to provide a connector to circuit board sting arrangement which ensures the stability of the mechanical connection between the connector and the printed circuit board and of the orientation of a holding device thereof.
An electrical connector in accordance with the present invention comprises an insulative housing, a plurality of electrical contacts mounted in the insulative housing, and a holding device.
The insulative housing comprises a top wall, a bottom wall, and two side walls. One of the side walls forms a pair of plates on a lower outside surface thereof, the plates defining a guiding channel therebetween and a pair of engaging grooves between the plates and the side wall and in communication with the guiding channel.
The holding device includes an interferential portion, a transitional portion, and a mounting portion. The interferential portion is interferentially fitted into the engaging grooves of the insulative housing. The mounting portion is secured to a printed circuit board and is connected with the interferential portion via the transitional portion.
