DESCRIPTION:
BRIEF SUMMARY
The invention relates to the field of coaxial type components for use at high frequencies. More precisely, it relates to a miniature component that forms both a connector and a switch.
More and more portable type appliances are being used that operate at high frequencies. The most common are car radiotelephones which can be used either in a car, in which case the appliance is connected to an antenna of the car, or else outside it as a portable telephone, using an antenna incorporated in the appliance. It is therefore necessary for the appliance both to include a connector enabling it to be connected to an external car antenna, and also to possess a switch for switching between the two antennas.
The present invention relates to a connector-switch component designed to enable the above-mentioned switching to be performed automatically when the appliance is connected to and disconnected from an external antenna. More precisely, when the appliance is used as a portable appliance outside a car, the circuit of the appliance is connected to the external antenna via an internal contact. When the appliance is put into place in a car, it is placed in a connector incorporated in the car and connected to an external antenna, and the connector displaces a moving assembly which serves firstly to provide a connection between the external antenna and the internal circuit of the appliance, and secondly to disconnect and ground the second contact which is connected to the internal antenna of the appliance. Such grounding is particularly advantageous at high frequencies (particularly above 1 GHz) since otherwise the disconnected member can give rise to interference that spoils operation.
More precisely, the invention provides a coaxial type connector-switch component for high frequencies, comprising: a conductive body defining an elongate cavity and designed to be connected to ground; a first contact supported by a first insulating member at a first end of the elongate cavity in the body so as to be fixed relative to the body; a second contact supported by a second insulating member in a wall of the body so as to be accessible on one side of the elongate cavity and so as to be fixed relative to the body; an assembly that is movable in translation along an axis between a first position and a second position and comprising: a conductive member co-operating by sliding with the first contact with which it is in permanent contact, and possessing a moving contact which co-operates with the second contact when the moving assembly is in the first position and which is remote from the second contact when the moving assembly is in its second position; a ground conductive member electrically connected to the body and disposed around the insulating member of the moving assembly to which it is secured so that, in the first position of the moving assembly, it is remote from the second contact, and in the second position of the moving assembly, it co-operates with the second contact; and a third insulating member disposed around the conductive member and insulating it relative to the body; and a return device for returning the moving assembly towards its first position.
In one embodiment, the moving contact projects laterally from the conductive member of the moving assembly, and the connector-switch component further includes a guide device for providing guidance in translation and that is designed to prevent rotation of the moving assembly about its displacement axis. Preferably, the guide device comprises a cylindrical sector formed by the third insulating member and a complementary cylindrical sector formed by the first insulating member, the two cylindrical sectors co-operating via surfaces parallel to the displacement axis.
Preferably, the body of the component further includes an impedance-matching cavity formed inside the body around the moving contact.
Preferably, the ground conductor member is a conductive sleeve having a cylindrical body extended by two diametrically opposite arms, one of the arms being designed to co-operate wi
