Abstract
A triaxial contact (1) comprising three contacts (2, 3, 4) retained by a front insulator (5) which is anchored in a cavity (7) of a first cylindrical contact (2). A triaxial contact such that an intermediate contact (3) is harpooned inside a first receptacle of the front insulator. The front insulator is such that it has a second receptacle (30) allowing to accommodate and insulate the central contact. Said triaxial contact has a rear insulator (6) allowing to retain the intermediate contact and the central contact inside the cavity of the first contact.
Claims12
A contact of the triaxial type, comprising a first outer cylindrical contact, an intermediate contact and a central contact, these contacts being held together by mechanical means and electrically insulated from each other by an insulating member, wherein
- the insulating member includes a single-piece front insulator, the front insulator being held at a front end of a cavity of the first cylindrical contact by means of a first elastic lock, secured in a first groove,
- the intermediate contact being held in a first receptacle of the front insulator by a harpoon embedded in the material of the front insulator,
- the central contact being situated in a second receptacle of the front insulator, and being locked therein by a shoulder of the front insulator, further wherein the elastic lock/s have a conical shape, such that a portion with the greater diameter of the conical shape is situated at the front end which is designed to receive the complementary connector.
A process for assembling a triaxial contact including the steps of:
- (a) introducing an intermediate contact in a first receptacle of a front insulator from a front end of the front insulator,
- (b) securing a harpoon of the intermediate contact in a wall of this first receptacle,
- (c) introducing a central contact in a second receptacle of said front insulator from a rear end of the front insulator, the rear end being opposite to the front end of the front insulator,
- (d) engaging a rear insulator against the rear end of the front insulator, the rear insulator and the rear end of the front insulator having an intermediate contact pin and a central contact pin projecting therefrom,
- (e) introducing the assembly composed of the rear insulator, front insulator, intermediate and central contacts in a cavity of a cylindrical contact trough a front end of the cylindrical contact, and
- (f) locking said assembly against a step of the cylindrical contact by securing an elastic lock of the front insulator in a complementary groove of the cylindrical contact.
A contact of the triaxial type, comprising a first outer cylindrical contact, an intermediate contact and a central contact, these contacts being held together by mechanical means and electrically insulated from each other by an insulating member, wherein
- the insulating member includes a single-piece front insulator, the front insulator being held at a front end of a cavity of the first cylindrical contact by means of a first elastic lock, secured in a first groove,
- the intermediate contact being held in a first receptacle of the front insulator by a harpoon embedded in the material of the front insulator,
- the central contact being situated in a second receptacle of the front insulator, and being locked therein by a shoulder of the front insulator, further wherein the insulating member includes a rear insulator held by a rim at a rear end of the first cylindrical contact.
A contact of the triaxial type, comprising a first outer cylindrical contact, an intermediate contact and a central contact, these contacts being held together by mechanical means and electrically insulated from each other by an insulating member, wherein
- the insulating member includes a single-piece front insulator, the front insulator being held at a front end of a cavity of the first cylindrical contact by means of a first elastic lock, secured in a first groove,
- the intermediate contact being held in a first receptacle of the front insulator by a harpoon embedded in the material of the front insulator,
- the central contact being situated in a second receptacle of the front insulator, and being locked therein by a shoulder of the front insulator, further wherein the central contact includes a socket at its front end, and that the second receptacle has an orifice at the same front end, the orifice having a diameter slightly smaller than the inside diameter of the socket.
