Abstract

A connector for electrical contacting that includes a body configured to mechanically retain at least one electrically conductive contact, which is accessible on an exit side of the body for electrically contacting at least one other electrical contact. The body is constructed from at least two different components, with a first component of the at least two different components at least substantially forming the exit side and being made from a fire-retardant plastic, and a second component of the at least two different components having an ignition point which is lower than an ignition point of the first component of the at least two components, and the second component of the at least two different components having an elasticity which is greater than an elasticity of the first component of the at least two different components.

First claim

The invention claimed is:

1. A connector for electrical contacting, said connector comprising:
a body configured to mechanically retain at least one electrically conductive contact, which is accessible on an exit side of the body for electrically contacting at least one other electrical contact, said body being constructed from at least two different components, with a first component of the at least two different components at least substantially forming the exit side, the first component comprising the at least one electrically conductive contact, and the first component being made from a fire-retardant plastic, and a second component of the at least two different components having an ignition point which is lower than an ignition point of the first component of the at least two components, and the second component of the at least two different components having an elasticity which is greater than an elasticity of the first component of the at least two different components.

2. The connector of claim 1 , wherein the first component of the at least two different components is sized to take up a predominant share of a volume of the connector.

3. The connector of claim 1 , wherein the second component of the at least two different components is latched onto the one of the at least two components.

4. The connector of claim 1 , wherein the second component of the at least two different components is configured to allow mechanical connection of a plurality of said connector.

5. The connector of claim 4 , wherein the second component of the at least two different components is sized to extend over the multiple connectors to thereby form a chain.

6. The connector of claim 1 , wherein the second component of the at least two different components comprises a locking latch.

7. The connector of claim 1 , wherein the second component of the at least two different components is made from a standard plastic.

8. The connector of claim 1 , wherein the second component of the at least two different components is made from Schulamid.

9. The connector of claim 1 , wherein the connector is configured to conduct an electric current with a current strength of more than 2 amperes.

10. The connector of claim 1 , wherein the first component of the at least two different components is made of a material having a melting point which exceeds 260° C.

11. The connector of claim 1 , wherein the first component of the at least two different components is made of a material which is classified in flammability class V-0 under the test standard UL94.

12. The connector of claim 1 , wherein the first component of the at least two different components is made of a material which has a dielectric strength of more than 240 V.

13. The connector of claim 1 , wherein the first component of the at least two different components is made of fiber-reinforced material.

14. The connector of claim 13 , wherein the fiber-reinforced material includes glass fibers and/or mineral fibers.

15. The connector of claim 1 , wherein the first component of the at least two different components is made of Fortron 4665 B6.

16. The connector of claim 6 , wherein the locking latch of the second component of the at least two different components is configured to retain the connector in an installed position in a form-fit manner on a base plate of a pump into which the electrically conductive contact of the connector is insertable.

17. The connector of claim 1 , wherein the connector is a standard Rast 2.5, Rast 3 or Rast 5 connector.
