It is known to use several types of electrical connectors (including plug and socket type devices) to electrically connect electronic circuits implemented on a printed circuit board PCB to a remote device. The remote device may, for example, be a power supply that supplies current to the electronic circuit via a wiring harness having at least one wire connected in an electrical connector. The electrical connector is connected to the electronic circuitry on the PCB.

A particular type of connector known in the art is a "kard" connector. The connector has a main body for connecting wires of a wire harness. A pair of opposing jaws extend from the body and are configured to receive a printed circuit board supporting an electronic circuit therebetween. The latch includes an electrical contact that is electrically connected to the wire harness through the body of the connector. The arrangement is such that electrical contacts on the jaws establish contact with corresponding conductive areas on the PCB sandwiched between the jaws.

However, if the PCB is not properly inserted between the jaws of the kard connector, or if either or both of the printed circuit board and the connector are subjected to vibration or shock during use, the connector may become disconnected from the PCB. Such events can only be handled by manual intervention. When the kard connector is used in a shared vehicle, the vehicle is subjected to vibration or shock, so that the connector may be disconnected during use.

Furthermore, due to the particularity of the shared vehicle use, the electrical connector is also required to have certain waterproof performance, and obviously, the kardel connector does not have the waterproof performance.
