Abstract

The invention relates to a connection unit of universal type. This comprises two complementary connection elements (1,2) with a coaxial structure having at least one peripheral part and a central conductive core. The peripheral part(s) of one of the connection elements (1) are in sleeve form. The sleeves (10) and the contact (11) are mounted movably in translation in the direction of the longitudinal axis Δ of the male element (1). The sleeves (10) and the contact (11) are mechanically independent. The connector of this invention has application to connectors for radio frequency and/or numerical or analog signals.

Claims

1. A universal connection unit with a coaxial structure comprising:

two complementary connection elements called a male element and a female element;

each said connection element comprising;

at least one peripheral sleeve having a planar outer end surface, said sleeve forming a connection mass and

a central core including a contact having a planar outer end surface, said core electrically isolated from said at least one peripheral sleeve;

said at least one sleeve and said contact of said male element being mounted moveably in translation in the direction of the longitudinal axis of said male element;

said at least one sleeve and said contact of said male element being mechanically independent; and

said contact planar outer end surface and the planar outer end surface of said at least one sleeve of said female element having substantially identical electric sections and dimensions in a plane perpendicular to the longitudinal axis of said connection unit as those of said male elements;

wherein electric connection between said two connection elements is ensured by bringing into flush abutment the planar outer end surfaces of said respective peripheral sleeves and contacts.

2. A connection unit according to claim 1, wherein its conductive parts are constituted in a coated copper alloy, and its insulating parts being constituted in polytetrafluorethylene.

3. A connector according to claim 1, wherein said male and female connection elements are arranged in a block of insulating material constituting said male and female parts respectively of the connector body, said male and female parts being provided with centering and fixing means.

4. A connection unit according to claim 1 wherein upon connection and electrical transmission said unit has a loss through transmission less than one decibel over a frequency band in the ratio of 10 for a maximum neighboring frequency greater than 1 GHz.

5. A connection unit according to claim 1 wherein said at least one sleeve and said contact of said male connection element are provided with spring means for elastic return permitting their maintenance in mechanical and electrical contact with said at least one sleeve and said contact of said female element respectively.

6. A connection unit according to claim 5, wherein said male connection element comprises at least:

an insulating cylindrical body mechanically fixed to a body of said male element in which is mounted slidingly in the region of the longitudinal axis thereof said contact forming said central core, and

a tubular conducting element, constituting one of said at least one sleeve, engaged slidingly on said cylindrical insulating body, said tubular conducting element having in a plane perpendicular to its lengthwise direction a rib, said spring means being engaged on said sleeve and acting on said sleeve by the intermediary of said rib and of a fixed part of said male connection element on which said spring means takes abutment, the parts of said sleeve on which said spring is engaged being constituted by a slit sleeve having a plurality of elastic blades.

7. A universal connection unit with a coaxial structure comprising:

two complementary connection elements called a male element and a female element;

each said connection element comprising;

at least one peripheral sleeve forming a connection mass and

a central core constituted by a contact electrically isolated from said at least one peripheral sleeve;

said at least one sleeve and said contact of said male element being mounted moveably in translation in the direction of the longitudinal axis of said male element;

said at least one sleeve and said contact of said male element being mechanically independent;

said contact and said at least one sleeve of said female element having substantially identical electric sections and dimensions in a plane perpendicular to the longitudinal axis of said connection unit as those of said male element;

wherein electric connection between said two connection elements is ensured by bringing into flush abutment said respective peripheral sleeves and contacts;

wherein said at least one sleeve and said contact of said male connection element are provided with means for elastic return permitting their maintenance in mechanical and electrical contact with said at least one sleeve and said contact of said female element respectively;

wherein said male connection element comprises at least;

an insulating cylindrical body mechanically fixed to a body of said male element in which is mounted slidingly in the region of the longitudinal axis thereof said contact forming said central core; and

a tubular conducting element, constituting one of said at least one sleeve, engaged slidingly on said cylindrical insulating body, said tubular conducting element having in a plane perpendicular to its lengthwise direction a rib, said elastic return means being engaged on said sleeve and acting on said sleeve by the intermediary of said rib and of a fixed part of said male connection element on which said spring takes abutment, the parts of said sleeve on which said elastic return means is engaged being constituted by a slit sleeve having a plurality of elastic blades; and

wherein said contact forming said central core comprises;

a substantially cylindrical connection base having a shoulder, said shoulder of said connection base being embedded in said insulating cylindrical body in a manner to leave free a connection zone outside said insulating body intended to receive a conductor of a cable to be connected, and a contact needle inside of a housing of said insulating cylindrical body,

a contact element constituting at one end a solid cylindrical contact member and at the other end extending lengthwise form a shoulder in a plane perpendicular to the lengthwise direction of said cylindrical contact member an element of slit sleeve type, said elastic return means acting on said contact being engaged on said slit sleeve and on said contact needle between said shoulders of said cylindrical element and of said connection base respectively on which said elastic return means abuts, said contact needle being able to be engaged in said slit sleeve on connection of said connection unit.
