Abstract

A fluid-tight contact implementation includes a plastic body and a flat contact(s). The plastic of the plastic body is composed of a non-shrinking, duroplastic material. The flat contact has a region encapsulated by the plastic body. The encapsulated region of the flat contact has a cross-sectional width which varies along an axial direction of the flat contact. Longitudinal edges of the encapsulated region of the flat contact along the axial direction are rounded.

Claims

1. A fluid-tight contact implementation comprising:

a plastic body, wherein the plastic of the plastic body is composed of a non-shrinking, duroplastic material; and

a flat contact having a region encapsulated by the plastic body, the region of the flat contact having a cross-sectional width which varies along an axial direction of the flat contact, wherein longitudinal edges of the region of the flat contact along the axial direction are rounded.

2. The contact implementation of claim 1 wherein:

the region of the flat contact includes recesses which cause the cross-sectional width of the region of the flat contact to vary along the axial direction of the flat contact.

3. The contact implementation of claim 2 wherein:

the recesses are rounded.

4. The contact implementation of claim 2 wherein:

the recesses are rectangular shaped.

5. The contact implementation of claim 1 wherein:

the plastic body and the flat contact have at least similar thermal expansion coefficients.

6. The contact implementation of claim 1 wherein:

a bonding agent is applied between plastic body and the region of the flat contact.

7. The contact implementation of claim 1 wherein:

the plastic body forms a plug-in connector housing.

8. The contact implementation of claim 1 further comprising:

a plurality of other flat contacts, each of these flat contacts having a region encapsulated by the plastic body, the region of each of these flat contacts having a cross-sectional width which varies along an axial direction of these flat contacts, wherein longitudinal edges of the region of each of these flat contacts along the axial direction are rounded.

9. The contact implementation of claim 1 wherein:

the flat contact further includes end sections at opposite ends of the encapsulated region of the flat contact, wherein the end sections are not encapsulated by the plastic body.

10. The contact implementation of claim 9 wherein:

the non-encapsulated end sections of the flat contact are treated by a galvanic process and the encapsulated region of the flat contact is not treated by the galvanic process.

11. The contact implementation of claim 9 wherein:

the non-encapsulated end sections of the flat contact include at least one of a tin and silver coating and the encapsulated region of the flat contact does not include either a tin or silver coating.

12. The contact implementation of claim 1 wherein:

the longitudinal edges of the flat contact are embossed in a stamping process and thereby rounded circumferentially.

13. The contact implementation of claim 1 wherein:

the non-shrinking, duroplastic material includes an epoxy resin, a phenol resin, or a bulk molding compound with non-shrinking properties.
