ABSTRACT:
TECHNICAL FIELD
The present invention relates to a sealing arrangement between an electrical connector and an electrical conductor, and in particular to a sealing arrangement between an electrical connector and a substantially flat electrical conductor (such as a flexible print circuit).
BACKGROUND OF THE INVENTION
In order to electrically connect a flexible printed circuit (FPC) to another FPC or to an electrical component, it is necessary to secure a electrical connector to the FPC. In such an arrangement, the FPC passes through an aperture in the housing of the electrical connector. To provide a substantially watertight seal between the FPC and the housing, the housing or part of the housing is moulded around the FPC or the FPC is secured to the housing by hot-melt adhesive. These known arrangements have disadvantages in terms of assembly or processing time, and temperature stresses on the FPC.
SUMMARY OF THE INVENTION
It is an object of the present invention to overcome the above mentioned disadvantages.
A sealing arrangement in accordance with the present invention between an electrical connector and an electrical conductor in which the electrical conductor extends through an aperture in a housing of the electrical connector, the sealing arrangement being positioned adjacent the aperture and comprising a flap member which is pivotally mounted and movable between an open position and a closed position, the flap member being positioned on one side of the electrical conductor; a wall positioned on the opposite side of the electrical conductor to the flap member; and a compressible seal positioned around the electrical conductor; wherein, in the closed position of the flap member, the flap member, the wall and the electrical conductor lie in planes which are substantially parallel; and the seal is compressed between the flap member and the wall and partially extruded into the aperture.
Compared to previously known arrangements, the present invention provides a sealing arrangement which is quicker and easier to assemble, and which does not subject the electrical connector to temperature stresses.
