Abstract

An electrical connector with snap-in compliant arm members, an alignment member and a plurality of pin members for mating with openings on a PCB.

First claim

What is claimed is:

1. A connector comprising:
a connector housing having a flange member, a socket connector, a body portion, a compliant snap-in arm member and an alignment member, the socket connector being disposed at a first end of the connector housing and extending from the flange member in a first direction, the socket connector defining a connector cavity, a rib member and a locking member, the connector cavity being adapted to receive a plurality of leads therein, the rib member being adapted to guide a mating connector into engagement with the connector along a coupling axis, the locking member being adapted to engage a mating locking member on the mating connector to fixedly but releasably couple the connector to the mating connector, the body portion extending from the flange member in a second direction opposite the first direction, the connector housing having a second end at which a distal end of the body portion terminates,
the alignment member being coupled to the body portion proximate the second end of the connector housing; and
a plurality of compliant, electrically-conductive pin members extending from the body portion proximate the second end of the connector housing;
wherein the alignment member is offset from the plurality of pin members in a direction perpendicular to the coupling axis.

2. The connector of claim 1 wherein the pin members are disposed along respective longitudinal axes that are orthogonal to the coupling axis and the direction relative to the coupling axis in which the pin members are offset.

3. The connector of claim 1 wherein the compliant snap-in arm member comprises a barbed end member.

4. The connector of claim 1 wherein the alignment member defines an alignment opening.

5. The connector of claim 4 wherein each of the pin members extends from the connector housing along a respective pin member axis, and wherein the alignment opening is disposed along an axis that is parallel to pin member axes.

6. The connector of claim 1 wherein the pin member axes are perpendicular to a longitudinal axis of the body portion.

7. The connector of claim 1 , the connector housing further comprises a stop member mounted on the body portion between the flange member and the alignment member, wherein the compliant snap-in arm member comprises a beam and a barb, wherein the beam extends from the flange member parallel to the body portion, wherein the barb is disposed on an end of the beam opposite the flange member, and wherein the stop member is configured to limit pivoting of the snap-in arm member about the flange member toward the body portion.

8. The connector of claim 1 further comprising a sealing member mounted on the flange member.

9. The connector of claim 8 wherein the sealing member is an O-ring.

10. The connector of claim 1 further comprising at least one knock-out opening in the connector housing.

11. The connector of claim 10 wherein two knock-out openings are provided in the connector housing, the knock-out openings positioned in alignment on opposite sides of the connector housing.

12. A coolant pump comprising:
a housing that defines a housing cavity and a connector aperture, the housing cavity being formed along a first axis, the connector aperture being formed along a second axis that is transverse to the first axis, the connector aperture intersecting the housing cavity;
an electrical connector having a connector housing, an alignment member and a plurality of pin members, the connector housing having a flange member, a socket connector, a body portion, a compliant snap-in arm member and an alignment member, the socket connector being disposed at a first end of the connector housing and extending from the flange member in a first direction, the socket connector defining a connector cavity, a rib member and a locking member, the connector cavity being adapted to receive a plurality of leads therein, the rib member being adapted to guide a mating connector into engagement with the connector along a coupling axis, the locking member being adapted to engage a mating locking member on the mating connector to fixedly but releasably couple the connector to the mating connector, the body portion extending from the flange member in a second direction opposite the first direction, the connector housing having a second end at which a distal end of the body portion terminates, the alignment member being coupled to the body portion proximate the second end of the connector housing, the plurality of pin members extending from the body portion proximate the second end of the connector housing, wherein the connector is received through the connector aperture such that the flange member abuts an external surface of the housing member, wherein the compliant snap-in arm member engages an internal surface of the housing member to inhibit withdrawal of the connector from the connector aperture in a first direction along the second axis, wherein the pin members are disposed in the housing cavity and are oriented parallel to the first axis, and wherein the alignment member is coupled to the body portion proximate the second end of the connector housing;
a circuit board received into the housing cavity, the circuit board having circuit board terminals in electrical contact with the pin members; and
a threaded fastener disposed through the circuit board and the connector housing, the threaded fastener being threadably coupled to the housing member.

13. The coolant pump of claim 12 wherein the pin members are compliant pin members.

14. The coolant pump of claim 12 wherein the compliant arm member comprises a barbed end member.

15. The coolant pump of claim 12 the alignment member defines an alignment opening.

16. The coolant pump of claim 12 wherein the threaded fastener extends through the alignment opening.

17. The coolant pump of claim 15 wherein the alignment opening is disposed along an axis that is parallel to the first axis.

18. The coolant pump of claim 12 the connector housing further comprises a stop member mounted on the body portion between the flange member and the alignment member, wherein the compliant snap-in arm member comprises a beam and a barb, wherein the beam extends from the flange member parallel to the body portion, wherein the barb is disposed on an end of the beam opposite the flange member, and wherein the stop member is configured to limit pivoting of the snap-in arm member about the flange member toward the body portion.

19. The coolant pump of claim 18 further comprising a sealing member mounted on the flange member, the sealing member being sealingly engaged to the connector housing and the housing member.

20. The coolant pump of claim 19 wherein the sealing member is an O-ring.
