DETAILED DESCRIPTION

(6) The invention is described below with reference to exemplary embodiments and to FIGS. 1 to 4, wherein the same reference symbols indicate same functional and/or structural features.

(7) FIG. 1 shows a plan view of an unbent sheet metal part 1. The flat sheet metal part 1 has a rectangular base shape with edges 1a, 1b, 1c, 1d and four corner sections 2a, 2b, 2c, 2d. The two edges 1a, 1b extend parallel to one another. These edges 1a, 1b are the rims of the collar crosspieces 10, 20. The collar crosspieces 10, 20 extend between two corner sections 2a, 2b or 2c, 2d, respectively.

(8) A multitude of contact blades 4 extend between the collar crosspieces 10, 20, which blades 4 connect the two collar crosspieces 10, 20.

(9) Each collar crosspiece 10, 20 has a protrusion 11 lengthening the collar crosspiece in the region of the respective corner section 2a, 2c, which represents a part of the capturing geometry.

(10) Furthermore, each collar crosspiece 10, 20 forms a respective recess 12 in the region of the respective other corner section 2b, 2d, which also represents a part of the capturing geometry according to the invention.

(11) As is further visible, the front edge K of the sheet metal part 1 in the region of the collar crosspiece 10 is assigned the reference symbol K, and the rear edge of the collar crosspiece 20, i.e. the collar crosspiece located opposite the collar crosspiece 10, is also assigned the reference symbol K.

(12) FIGS. 2 and 3 show embodiments of a contract cage 3, which were formed, particularly rolled, from a sheet metal part 1 according to the invention. A receiving space 40 for plugging in a contact in the plug-in direction Z is formed in the contact cage 3.

(13) As is well visible in FIG. 2, the front-side edge K extends on the first collar crosspiece 10 parallel to the end-side edge K on the second collar crosspiece 20 and particularly in one plane in the region of the capturing geometries in the corner sections 2a, 2b, 2c, 2d, therefore in flush alignment and without a step-like offset.

(14) FIG. 4 shows a partial view one of the capturing geometries, which are formed from the protrusion 11 and the recess 12 and the other protrusion 32.

(15) The edge profile K in the region of the protrusion 11 of the collar crosspiece 10 is described in more detail below. It first runs linearly along the edge 1a of the collar crosspiece 10, then in a curved manner around the respective protrusion 11 in a bend 34 of about 180°, and then again in a bend 30 of about 90° [it transitions] into the edge section of a contact blade 4.

(16) It is further visible that the edge profile of the edge K extends as follows in the region of the recess 12 of the collar crosspiece 10. First linearly along the edge 1a of the collar crosspiece 10, then in a curved manner in a bend 31 of about 90° along the recess 12 and further in a bend of about 180° forming a protrusion 32, wherein the edge afterwards also transitions into the edge of a contact blade 4 in the present embodiment.

(17) Furthermore, the linear oblique sections 31a, 34a can be seen, which extend parallel or substantially parallel to one another and are provided on the respective opposite edge K in the region of the bend 31 of about 90°.

(18) It can further be seen that the protrusion 32 comprises an oblique section 32a which extends about parallel to the linear oblique section 34a of the edge K in the region of the bend 34. When rolling the sheet metal part together, the respective oblique sections 31a, 34a or the edges K of the capturing geometries abut, such that a desired end position of the edges 1a or 1c, respectively, is achieved.

(19) Furthermore, as shown in FIG. 2 and FIG. 3, the cylindrically shaped contact cage 3 is constricted in or near its center.

(20) In this state, the side edge 33 of the protrusion 32 which is facing in the direction of the edge 1a or 1c rests next to the recess 12 against the respective opposite side edge 13 of the edge K of the protrusion 11 in the region of the 90° bend 31.

(21) The protrusion 11 plunges into the recess 12, forming an end-side gap 14 to the edge K located on the opposite end side.

(22) The implementation of the invention is not limited to the preferred embodiments described above. Instead, a plurality of variants is conceivable in which the solution described is used for completely different designs.
