curved transverse slot 30 separated from the two sheet metal strips 1, 2 and comprises a bending leg 31 and a

Partition wall leg 32 which are separated by a bulge 33 in the transverse slot.

The longitudinal slot 10 between the metal strips 1, 2 still has an extension 14 in order to increase the spring compliance of the metal strips 1, 2 between a KontaktSchenkel 11 and a bending region 13. The lateral edges of the metal strips 1, 2 are aligned parallel to each other. Further, the metal strips 1, 2 are connected to each other via a bridge plate member 15, adjacent to the curved transverse slot 30. The angle plate 3 is connected via a web 16 with the bridge sheet metal part 15 and still has a journal extension 35, the

Terminal chamber finds, which by the

Partition wall legs 32 are separated from each other. The spring clamp is designed in DirektStecktechnik (so-called "direct push in"), the bare conductor ends 81, with or without ferrules, can be plugged directly into the connection chamber and there independently of the respectively associated loop clamping spring 21, 22 are clamped.

Referring to Fig. 8a, the

Inter-panel legs 32 include an upper free portion 32a that extends within the shaft-like opening 60 or the material passage, and a lower base portion 32b connected to the web 16. The base portion 32b thus extends the separation of the

Spaces for the conductor ends 81 to below the

Metal collar 63. Between the base portion 32b and the free portion 32a is further preferably a

Stop edge 32c is provided which forms a stop against a lower edge 61a of the intended for clamping collar wall or clamping wall 61 when the terminal spring element is inserted into the material passage, as shown in FIG. 9a. In this way, in conjunction with the obliquely upward, away from the intermediate wall leg 32 loop-clamping springs 21, 22, the connecting spring element can be securely held in the material passage.

If a number n of compartments or connection chambers per bay-like opening are to be formed, then n parallel metal strips and n-1 intermediate wall legs are formed on the sheet metal part to be punched out. Then, if necessary, more than three bending steps are carried out in order to achieve the

Connecting spring elements for n compartments to produce.
