Abstract

A connector is provided with a terminal position assurance (TPA) member that secures a terminal within a channel provided in a base. The TPA member can be secured to the base with a hinge that extends substantially a width of the base. The TPA member and the base can be formed as a one-piece molded part.

First claim

We claim:

1. A connector, comprising:
a housing with a base and a nose, the base including a first side and a second side and having a top surface that extends between the first and second side, the nose extending from the base, the housing including a channel that extends within the base and the nose;
a terminal positioned in the channel, the terminal including a bottom side, a top side and two adjacent sides, the terminal having a contact end with a contact width and a crimp with a crimp width, the terminal further includes at least one projection extending above the top side; and
a terminal position assurance (TPA) member extending from the top surface of the base, the TPA member having a hinge that substantially extends from the first side to the second side of the base, the hinge extending from the top surface and connecting the TPA member to the top surface, the TPA member including a rear edge that is configured to rotate approximately 180 degrees so as to press against the base, the TPA member including a pushing flange that extends past the rear edge, the pushing flange configured to be inserted into the channel, the pushing flange engaging the projection so as to prevent the terminal from translating past the TPA member.

2. The connector of claim 1 , wherein the hinge extends a first distance from the top surface, wherein the pushing flange extends past the rear edge a second distance, and wherein the first distance is greater than the second distance.

3. The connector of claim 2 , wherein a plurality of terminals are provided, and wherein the housing includes a plurality of noses extending from the base and a plurality of channels that extend within the base and the noses, each nose being spaced apart from an adjacent nose so that there is an air gap between two adjacent noses, and wherein each nose has a single channel extending therein and each channel has a single terminal positioned therein.

4. The connector of claim 1 , wherein the channel has a first width in the nose and a second width in the base, the second width being greater than the first width and the first width being greater than the contact width.

5. The connector of claim 4 , further comprising a tapered portion in the channel, the tapered portion providing a transition from the second width to a third width that is less than the first width.

6. The connector of claim 5 , wherein the terminal includes at least one wing and the channel includes a shoulder, the wing configured to engage the shoulder and prevent removal of the terminal once the terminal is inserted into the channel.
