Abstract

In the case of an electric socket contact for insertion into a socket housing with a sleeve body and a laminated cage, which is attached axially to said sleeve body, for the displaceably pressing reception of a contact pin and attachment means, which are designed at the sleeve body, e.g. crimp extensions for connecting leads, there are for the purpose of making early contact and a reliable central guide of the contact pin the laminated cage (4), which is formed by a cylindrically rolled flat sheet metal blank (6), which exhibits a cylindrical base member (7) with two contact tongues (8), which are punched diametrically to each other and which are bent into the laminated cage in the direction of the free end and then are bent back toward the outside; and a cylindrical annular member (9) reaches at a distance over the free ends (8'"'"') near the plug opening (13); and wherein at a distance there are strip elements (14), which are connected rigidly to the annular member (9) and the base member (7) next to the contact tongues (8) and which exhibit depressions (10), hollows or the like, which point in the direction of the center longitudinal axis of the laminated cage, as mechanical guide members for the contact pin (11).

Claims

1. An electric socket contact for insertion into a socket housing with a sleeve body and a laminated cage attached axially to said sleeve body for displaceably pressing reception of a contact pin and attachment means, said sleeve body being attached to extensions for connecting leads, wherein said laminated cage is formed from a cylindrically rolled flat sheet metal blank comprising a cylindrical base member with two contact tongues extending diametrically opposite to each other and bent into said laminated cage in the direction of the free end and then bent back outwardly, and a cylindrical annular member spaced from and extending over said free ends adjacent a plug opening, and strip elements spaced from said contact tongues and rigidly connected to said annular member and said base member adjacent to said contact tongues and which comprise depressions projecting towards the central longitudinal axis of said laminated cage and constituting mechanical guide means for said contact pin.

2. The socket contact according to claim 1, wherein said contact tongues have a uniform width in a longitudinal direction over an entire length of said contact tongues.

3. The socket contact according to claim 1, wherein said contact tongues have a decreasing width in a direction of said free end in a longitudinal direction.

4. The socket contact according to claim 1, wherein said contact tongues have a decreasing width in a direction of said free end and are delimited in a longitudinal direction by side faces extending asymmetrically to each other.

5. The socket contact according to claim 1, wherein said depressions extend substantially over the entire length of said spring tongues so as to project into said laminated cage.

6. The socket contact according to claim 1, wherein for axial fixing in position in the sleeve body, said base member of said laminated cage is braced against a bend of said sleeve body, and wherein an end of said sleeve body extends clampingly over an outer edge of said annular member facing away from said base member.
