Abstract

An electrical connector assembly includes an electrical terminal having an attachment end and a connection end, a first terminal housing having a first cavity in which the attachment end is disposed. The first cavity defining a terminal extension opening through which the connection end extends. The assembly also includes a second terminal housing having a second cavity in which the connection end is disposed. The second cavity defining a terminal reception opening through which the connection end is received. The first terminal housing defines a first attachment surface surrounding the terminal extension opening and the second terminal housing defines a second attachment surface surrounding the terminal reception opening. The first attachment surface is sealed to the second attachment surface. The first attachment surface forms a first angle relative to the longitudinal axis and the second attachment surface forms a second angle relative to the lateral axis.

Claims

1. An electrical connector assembly, comprising:

an electrical terminal having an attachment end extending along a longitudinal axis configured to be attached to a wire cable and a connection end extending along a lateral axis configured to be attached to a corresponding mating terminal;

a first terminal housing having a first cavity extending along the longitudinal axis in which the attachment end is disposed, the first cavity defining a cable opening through which the wire cable extends and defining a terminal extension opening through which the connection end extends; and

a second terminal housing having a second cavity extending along the lateral axis in which the connection end is disposed, the second cavity defining a terminal reception opening through which the connection end is received and a mating opening configured to receive the corresponding mating terminal, wherein the first terminal housing defines a first attachment surface surrounding the terminal extension opening and the second terminal housing defines a second attachment surface surrounding the terminal reception opening, wherein the first attachment surface is sealed to the second attachment surface, and wherein the first attachment surface forms a first angle relative to the longitudinal axis and the second attachment surface forms a second angle relative to the lateral axis.

2. The electrical connector assembly according to claim 1, wherein the second angle is complementary to the first angle.

3. The electrical connector assembly according to claim 1, wherein a first angular value of the first angle is about 45 degrees and a second angular value of the second angle is about 45 degrees.

4. The electrical connector assembly according to claim 1, wherein the first attachment surface defines a circumferential ridge surrounding the terminal extension opening and the second attachment surface defines a circumferential groove surrounding the terminal reception opening in which the circumferential ridge is received.

5. The electrical connector assembly according to claim 4, wherein the circumferential ridge is welded to the circumferential groove using an infrared laser welding process.

6. The electrical connector assembly according to claim 1, wherein the first attachment surface is welded to the second attachment surface, thereby forming a watertight joint between the first and second terminal housings.

7. The electrical connector assembly according to claim 1, wherein the first attachment surface is welded to the second attachment surface using a laser welding process.

8. The electrical connector assembly according to claim 1, wherein the first terminal housing is formed of first material and the second terminal housing is formed of a second material different than the first terminal housing.

9. The electrical connector assembly according to claim 8, wherein the first material is infrared transparent and the second material is infrared absorbent.

10. The electrical connector assembly according to claim 1, wherein the longitudinal axis of the attachment end is substantially perpendicular to the lateral axis of the connection end.

11. A method of manufacturing an electrical connector assembly, comprising the steps of:

providing an electrical terminal having an attachment end extending along a longitudinal axis configured to be attached to a wire cable and a connection end extending along a lateral axis configured to be attached to a corresponding mating terminal;

providing a first terminal housing having a first cavity extending along the longitudinal axis in which the attachment end is disposed, the first cavity defining a cable opening through which the wire cable extends and defining a terminal extension opening through which the connection end extends;

providing a second terminal housing having a second cavity extending along the lateral axis in which the attachment end is disposed, the second cavity defining a terminal reception opening through which the connection end is received and a mating opening configured to receive the corresponding mating terminal, wherein the first terminal housing defines a first attachment surface surrounding the terminal extension opening and the second terminal housing defines a second attachment surface surrounding the terminal reception opening;

inserting the attachment end of the electrical terminal within the first cavity of the first terminal housing;

inserting the connection end of the electrical terminal within the second cavity of the second terminal housing; and

sealing the first attachment surface to the second attachment surface.

12. The method according to claim 11, wherein the first attachment surface defines a circumferential ridge surrounding the terminal extension opening and the second attachment surface defines a circumferential groove surrounding the terminal reception opening and wherein the method further includes the step of disposing the circumferential ridge within the circumferential groove.

13. The method according to claim 12, wherein the step of sealing the first attachment surface to the second attachment surface is performed by welding the circumferential ridge to the circumferential groove using an infrared laser welding process.

14. The method according to claim 11, wherein the step of sealing the first attachment surface to the second attachment surface is performed by welding the first attachment surface to the second attachment surface.

15. The method according to claim 11, wherein the step of sealing the first attachment surface to the second attachment surface is performed using a laser welding process.

16. The method according to claim 11, wherein the first terminal housing is formed of first material and the second terminal housing is formed of a second material different than the first terminal housing.

17. The method according to claim 16, wherein the first material is infrared transparent and the second material is infrared absorbent.

18. The method according to claim 11, wherein the longitudinal axis of the attachment end is substantially perpendicular to the lateral axis of the connection end.
