Abstract

A household appliance includes a connector for electrical contacting. The connector includes a body configured to mechanically retain at least one electrically conductive contact, which is accessible on an exit side of the body for contacting. The body is constructed from at least two different components, with one of the at least two components at least substantially forming the exit side and being made from a fire-retardant plastic.

First claim

The invention claimed is:

1. A household appliance comprising:
a pump having a base plate with at least one electrical contact; and
a separate and distinct 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 the at least one electrical contact of the base plate of the pump, 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 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.

2. The household appliance 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 household appliance 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 household appliance 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 household appliance 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 household appliance of claim 1 , wherein the second component of the at least two different components comprises a locking latch.

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

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

9. The household appliance of claim 1 , wherein the connector is connected internally in the household appliance.

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

11. The household appliance of claim 1 , wherein the household appliance comprises a household dishwasher and the pump comprises a heat pump of the household dishwasher.

12. The household appliance 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.

13. The household appliance 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.

14. The household appliance 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.

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

16. The household appliance of claim 15 , wherein the fiber-reinforced material includes glass fibers and/or mineral fibers.

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

18. The household appliance 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 the base plate of the pump into which the electrically conductive contact of the connector is insertable.

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

20. A household dishwasher comprising:
a heat pump having a base plate with at least one electrical contact; and
a separate and distinct connector, 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 the at least one electrical contact of the base plate of the heat pump, 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 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.
