Abstract

An electrical connector is provided with unitarily molded housing and a wire seal cover mounted to the rear end of the housing. A latch extends from a wall of the housing and includes a forwardly projecting locking beam and a rearwardly projecting actuator. The housing further includes a shroud unitarily molded therewith to cover both sides and the top of the locking beam of the latch. The wire seal cover further includes a shroud for protecting the actuator of the latch. However, at least a portion of the shroud on the wire seal cover is open to enable actuation of the latch for unmating the connector.

Claims

1. An electrical connector having a unitarily molded first housing structure and a unitarily molded second housing structure in locked engagement with the first housing structure, said first and second housing structures together adapted to contain a single set of electrical terminals which can mate with a complementary electrical connector the first housing structure comprising latch means for locked but releasable mating of said electrical connector with a second connector, said latch means comprising deflectable locking means for lockingly engaging the second connector and actuating means for selectively deflecting the locking means, said first housing structure further comprising a first shroud at least partly enclosing a first portion of said latch means, said second housing structure comprising a second shroud at least partly enclosing a second portion of said latch means of said first housing structure, whereby the first and second shrouds combine to substantially prevent the latch means from snagging wires and accumulating debris.

2. An electrical connector as in claim 1 wherein said first shroud partly encloses the locking means, and wherein the second shroud partly encloses the actuating means.

3. An electrical connector as in claim 1 wherein the first housing structure comprises a body for receiving electrical terminals therein, said latch means comprising a root extending from the body, the locking means of the latch means defining a locking beam extending deflectably from the root in a first direction, the actuating means of the latch means defining an actuator extending in a second direction from the root and being substantially rigid with the locking beam.

4. An electrical connector as in claim 3 wherein said first shroud comprises at least one shroud wall extending generally parallel to the locking beam, and wherein the second shroud comprises at least one wall extending generally parallel to the actuator.

5. An electrical connector as in claim 4 wherein the wall of the first shroud is disposed in engagement with the wall of the second shroud.

6. An electrical connector as in claim 4 wherein the first shroud comprises a pair of side walls disposed on opposite respective sides of the locking beam and a top wall extending unitarily between the side walls such that the locking beam is disposed intermediate the top wall of the shroud and the body of the housing.

7. An electrical connector as in claim 6 wherein the second shroud comprises a pair of side walls disposed on opposite respective sides of the actuator, the side walls of the second shroud engaging the side walls of the first shroud.

8. An electrical connector as in claim 7 wherein the second shroud further comprises an end wall extending from the second housing structure between the side walls of the second shroud and in spaced relationship to the actuator.

9. An electrical connector as in claim 8 wherein the second shroud further comprises a top wall extending between the side walls of the second shroud and generally adjacent the top wall of the first shroud, the top wall of the second shroud being in spaced relationship to the end wall thereof for permitting access to the actuator of the latch means.

10. An electrical connector comprising a housing having a body defining a forward mating end, a rearward wire receiving end and a plurality of terminal receiving cavities extending therebetween, said housing comprising a deflectable latch for locking the mating end of the housing body with a second connector, a wire seal cover lockingly engaged with the rear wire receiving end of the housing body, wherein the improvement comprises:

the latch being unitarily molded with the connector housing and comprising a route extending from the body of the housing, a locking beam in spaced relationship to the housing body and extending deflectably forwardly toward the mating end thereof, an actuator in spaced relationship to the housing body and extending substantially rigidly from the locking beam rearwardly toward the rearward wire receiving end of the body;

a pair of housing side shroud walls unitary with the housing and disposed on opposite respective sides of the locking beam for preventing accumulation of debris between the locking beam and the housing body; and

a pair of cover shroud side walls unitary with the wire seal cover and disposed on opposite respective sides of the actuator for preventing accumulation of debris intermediate the actuator and the body of the housing.

11. An electrical connector as in claim 10 further comprising a housing top shroud wall extending unitarily between the housing side shroud walls such that the locking beam is intermediate the housing top shroud wall and the body of the housing.

12. An electrical connector as in claim 11 further comprising a cover rear shroud wall extending unitarily from the wire seal cover and between the cover side shroud walls, said cover rear shroud wall being disposed in spaced relationship to the actuator and intermediate the actuator and the rear wire receiving end of the connector.

13. An electrical connector as in claim 12 further comprising a cover top shroud wall extending unitarily between the cover side shroud walls and in spaced relationship to the cover rear shroud wall such that the actuator is accessible intermediate the side, rear and top shroud walls of the cover, the top shroud wall of the cover being in abutting engagement with the top shroud wall of the housing.
