Abstract

A connector position assurance (CPA) device for assuring the full engagement of a female connector assembly and a male connector assembly in a connector apparatus, and the connector apparatus having the female connector assembly and the male connector assembly engaged together when the CPA device is at a full-lock position. Prior to the CPA device being at a full-lock position, the female connector assembly, with the CPA device at a pre-lock position therein, enters the male connector assembly for engagement thereto. At such time, protruding members of a flexible member of the female connector assembly enter a side elongated slot of the male connector assembly. When the CPA device, at the pre-lock position, is further pushed into the female connector assembly, a set of side ledges extending from the CPA device prevents the flexible member of the female connector assembly from being moved or pushed; thus, with the CPA device at the full-lock position, it is assured that the male and female connector assemblies remain fully engaged.

Claims

1. A connector apparatus, comprising:

a female connector assembly for receiving a set of terminals, wherein the female connector assembly has an opening at one end thereof;

a male connector assembly for receiving another set of terminals, wherein the male connector assembly receives therein the female connector assembly for engagement thereto; and

a connector position assurance (CPA) device for entering the opening of the female connector assembly, and assures the full engagement of the male and female connector assemblies when the CPA device is at a full-lock position,

wherein the CPA device includes at least a flexible member having a substantially elongated slot for accommodating therein a substantially ramp-like member of the female connector assembly when the CPA device is at a full-lock position.

2. The connector apparatus as in claim 1, wherein the female connector assembly includes members for allowing the CPA device to be at a pre-lock position therein during transport of the female connector assembly.

3. The connector apparatus as in claim 1, wherein the CPA device includes a first flexible member having a portion thereof that enters a first window of the female connector assembly when the CPA device is at a pre-lock position.

4. The connector apparatus as in claim 3, wherein the device includes a second flexible member that traverses a substantially ramp-like member inside the female connector assembly and mounts onto an upper part of the substantially ramp-like member when the CPA device is at a pre-lock position.

5. The connector apparatus as in claim 3, wherein the portion of the first flexible member of the CPA device enters a second window of the female connector assembly when the CPA device is at a full-lock position.

6. The connector apparatus as in claim 4, wherein the upper portion of the substantially ramp-like member of the female connector assembly enters the substantially elongated slot of the second flexible member of the CPA device when the CPA device is at a full-lock position.

7. A connector position assurance (CPA) device for engaging female and male connector assemblies together in one of a pre-lock position and a full-lock position, the CPA device comprising:

a first flexible member; and

a second flexible member,

wherein the second flexible member has a substantially elongated slot for accommodating therein a substantially ramp-like member of the female connector assembly when the CPA device is at a full-lock position.

8. The CPA device as in claim 7, wherein the first flexible member includes a portion that enters a first window of the female connector assembly when the CPA device is at a pre-lock position.

9. The CPA device as in claim 7, wherein the second flexible member traverses a substantially ramp-like member inside the female connector assembly and mounts onto an upper part of the substantially ramp-like member when the CPA device is at a pre-lock position.

10. The CPA device as in claim 8, wherein the portion of the first flexible member enters a second window of the female connector assembly when the CPA device is at a full-lock position.

11. The CPA device as in claim 9, wherein the upper portion of the substantially ramp-like member of the female connector assembly enters the substantially elongated slot of the second flexible member when the CPA device is at a full-lock position.

12. The CPA device as in claim 11, further comprising at least a side ledge that is positioned beneath a flexible member of the female connector assembly when the CPA device is at a full-lock position,

wherein the flexible member of the female connector assembly includes protruding members that are inside an elongated slot of the male connector assembly to prevent the female connector assembly from being pulled away from the male connector assembly with the side ledge assuring that the flexible member of the female connector assembly is unable to move, thereby assuring that the male and female connector assemblies remain fully engaged when the CPA device is at a full-lock position.

13. A female connector assembly for engaging with a male connector assembly, comprising a flexible member;

and a side with a first window and a second window,

wherein a CPA device as in claim 7 enters the female connector assembly at the pre-lock position when the CPA device engages with the female connector assembly at the first window thereof, and at the full-lock position when the CPA device engages with the female connector assembly at the second window thereof.

14. A male connector assembly for engaging with a female connector assembly, comprising a side having an elongated slot for accommodating therein protruding members of a flexible member of the female connector assembly when the CPA device as in claim 7 is at one of the pre-lock position and the full-lock position inside the female connector assembly.

15. A method for assembling a male connector assembly and a female connector assembly, comprising the steps of:

inserting a connector position assurance (CPA) device and a female terminal position assurance (TPA) device, at pre-lock positions, into the female connector assembly;

inserting a male terminal position assurance (TPA) device, at a pre-lock position, into the male connector assembly;

inserting the female TPA device and the male TPA device, at full-lock positions, into the female connector assembly and the male connector assembly, respectively;

inserting the female connector assembly into the male connector assembly; and

further inserting the CPA device into the female connector assembly at a full-lock position to assure that the male and female connector assemblies remain engaged,

wherein the step of inserting the CPA device into the female connector assembly at a full-lock position includes the step of a substantially elongated slot of at least a flexible member of the CPA device accommodating therein a substantially ramp-like member of the female connector assembly.

16. The method for assembling the male connector assembly and the female connector assembly as in claim 15, further comprising the step of transporting the male and female connector assemblies with the CPA device at the pre-lock position and with the male and female TPA devices at the pre-lock positions.
