Abstract

The male connector (10) comprises a first connector body (14) comprising electrical contacts (54, 56) extending towards the free insertion end (44) of the first connector body (14) and provided with free end portions (58) that are elastically deformable. The first connector body (14) comprises a plug portion (18) extending in the insertion direction and being provided with first hook-like extensions (46) at its free ends extending laterally outward. The hook-like extensions (46) cover the free end portions (58) of the electrical contacts (54, 56) of the first connector body (14) which are elastically biased outwardly to engage the first hook-like extensions (46). Moreover, the female connector (12) comprises a second connector body (16) with electric contacts (98, 100) extending towards the insertion end and being provided with free end portions (104) which are elastically deformable. The second connector body (16) comprises a socket portion (72) enclosing the electrical contacts (98, 100) and comprising the insertion opening, the edge (90) defining this opening being provided with further hook-like extensions (92) extending radially inward.

Claims

1. A male connector,

comprising a first connector body provided to be inserted into a second connector body of a female connector,

said first connector body comprising electrical contacts extending towards the free insertion end of said first connector body and being provided with free end portions that are elastically deformable,

and a plug portion extending in the insertion direction of said first connector body, said plug portion being provided with first hook-like extensions at its free end extending radially outward,

said first hook-like extensions being arranged to cover the free end portions of the electrical contacts of said first connector body which are elastically biased outwardly to engage said first hook-like extensions,

wherein said plug portion of said first connector body comprises a narrowing portion that narrows its cross section towards the insertion end of said plug portion,

said narrowing portion being defined by wedge surfaces for supporting the electrical contacts of said first connector body in the assembled state of said first connector body and a second connector body.

2. The connector according to claim 1,

wherein said plug portion comprises a central plug member inserted between two wedge members, said central plug member extending beyond the ends of the wedge members and carrying said first hook-like extensions at its free end,

the electrical contacts of said first connector body being arranged to both sides of said wedge members.

3. The connector according to claim 1,

wherein the free end portions of the electrical contacts of said first connector body are provided with outwardly curved sections.

7. A connector arrangement,

comprising a male connector according to claim 1 and a female connector according to claim 4,

the first connector body of said male connector being provided to be inserted into the second connector body of said female connector so that the respective electrical contacts of said first connector body and said second connector body engage with each other.

8. The connector arrangement according to claim 7,

wherein said first connector body comprises a female receiving portion surrounding said plug portion and being provided to receive the socket portion of said second connector body.

4. A female connector,

comprising a second connector body provided to receive a first connector body of a male connector by insertion into said second connector body,

said second connector body comprising electrical contacts extending towards the free insertion end of said second connector body and being provided with free end portions that are elastically deformable,

said second connector body comprising a socket portion enclosing the electrical contacts and comprising an insertion opening at its free insertion end, the edge) defining said opening being provided with second hook-like extensions extending radially inward,

said second hook-like extensions being arranged to cover the free end portions of the electrical contacts of said second connector body which are elastically biased inwardly to engage said second hook-like extensions

wherein said socket portion of said second connector body comprises a widening portion that widens the free cross section within said socket portion towards the insertion opening of said socket portion,

said widening portion being defined by the wedge surfaces for supporting the electrical contacts of said second connector body in the assembled state of said first connector body and said second connector body.

5. The connector according to claim 4,

wherein said socket portion comprises wedge members forming inner walls of said socket portion and being inserted into a surrounding socket member that forms outer walls of said socket portion,

wherein said surrounding socket member extends beyond the ends of the wedge members and provides the edge defining said insertion opening,

said wedge members providing the wedge surfaces of said widening portion,

the electrical contacts of said second connector body being arranged on the inner walls formed by said wedge members.

6. The connector according to claim 4,

wherein the free end portions of the electrical contacts of said second connector body are provided with inwardly curved sections.
