The individual leaf spring areas 28 are on a holding element 30 arranged, which is bent to run along the insertion direction E via or on the screen housing 4 to be pushed to the spring clip fastener 20 to be arranged and fastened.

The holding element 30 has a return in unbent state at two opposite ends 31 with an undercut and a complementary projection, so that the undercut and the complementary projection in the bent state of the holding element 30 are in positive engagement and the retaining element 30 is held in the bent state. In particular, the return can 31 be formed dovetailed.

On the holding element 30 are to recesses 38 arranged in the corresponding projections 40 the spring clamp fastener 20 , in particular can intervene positively. By pressing or compressing the holding element on both sides 30 or the recesses 38 with the projections 40 arrive holding element 30 and spring clamp fastener 20 in positive engagement and / or friction, wherein the spring clip 6 on the shield housing 4 is attached.

Alternatively or additionally, the attachment can also be done by soldering, welding, gluing, riveting or the like.

6 shows a section through the Verbinderschirmung 2 in the rest position, ie before arranging on a printed circuit board or in a housing.

The spring clip 6 is not actuated or actuated along the actuation direction B1. Consequently, the contact area 22 the spring clip 6 in its rest position and consequently not deformed.

The holding element 30 is on a corresponding spring clip fastener 20 attached. By the positive engagement of the recesses 38 of the holding element 30 with the projections 40 the spring clamp fastener 20 is the spring clip 6 on the spring clip fastener 20 fixed and thus on the Schirmungsgehäuse 4 attached.

The curved leaf spring area 28 the spring clip 6 In particular, it comprises a shielding housing contact area 36 which is designed to be around the Schirmungsgehäuse 4 to contact mechanically and / or electrically. In particular, the electrical and / or mechanical contact takes place in the rest position by means of the Schirmungsgehäusekontaktbereich 36 outside the spring clip fastener 20 , Thus, the electrical contact between the Schirmungsgehäuse 4 and the spring clip 6 preferably be prepared in two ways at the same time.
