Abstract

A housing assembly for electrical connector includes a housing body and a locking lever pivotally connected to the housing body. The locking lever is pivotable relative to the housing body between a pre-locked position and a locked position. A groove is formed in an outer side surface of the housing body, and an elastic protrusion is formed on an inner side surface of the locking lever. The groove and the elastic protrusion are adapted such that the elastic protrusion is engaged into the groove when the locking lever is in the pre-locked position, and the elastic protrusion is disengaged from the groove when the locking lever is moved from the pre-locked position.

First claim

What is claimed is:

1 . A housing assembly for electrical connector, comprising:
a housing body including a groove formed in an outer side surface thereof, and a locking lever pivotally connected to the housing body and pivotable relative to the housing body between a pre-locked position and a locked position, the locking lever including an elastic protrusion formed on an inner side surface thereof, the groove and the elastic protrusion are adapted such that the elastic protrusion is engaged into the groove when the locking lever is in the pre-locked position, and the elastic protrusion is disengaged from the groove when the locking lever is moved from the pre-locked position.

2 . The housing assembly according to claim 1 , further comprising a sliding groove formed in the outer side surface of the housing body and located adjacent to the groove, the sliding groove adapted such that as the locking lever is pivoted from the pre-locked position to the locked position, the elastic protrusion disengaged from the groove enters into and is moved along the sliding groove.

3 . The housing assembly according to claim 2 , wherein the elastic protrusion further comprises:
an elastic sheet extending from the inner side surface of the locking lever; and a boss protruding from the elastic sheet.

4 . The housing assembly according to claim 3 , wherein two opposite ends of the elastic sheet extend from the inner side surface of the locking lever.

5 . The housing assembly according to claim 4 , wherein:
two sides of the elastic sheet adjacent to the two opposite ends are separated from the inner side surface of the locking lever; and the boss is arranged in a middle portion of the elastic sheet.

6 . The housing assembly according to claim 3 , wherein the boss is formed by bending the elastic sheet.

7 . The housing assembly according to claim 3 , wherein the elastic protrusion is integrally formed with the inner side surface of the locking lever.

8 . The housing assembly according to claim 3 , wherein a wall surface of the groove near the sliding groove is formed with a chamfer.

9 . The housing assembly according to claim 8 , wherein the boss defines an inclined face that matches the chamfer.

10 . The housing assembly according to claim 8 , wherein a wall surface of the sliding groove proximate the groove is formed with a chamfer.

11 . The housing assembly according to claim 2 , wherein the locking lever further comprises:
a pair of arm portions; and a connecting portion connected to the pair of arm portions.

12 . The housing assembly according to claim 11 , wherein the pair of arm portions are pivotally connected to the opposite outer side surfaces of the housing body.

13 . The housing assembly according to claim 12 , wherein the elastic protrusion is formed on an inner side surface of each arm portion of the pair of arm portions.

14 . The housing assembly according to claim 13 , wherein the groove and the sliding groove are correspondingly formed in each outer side surface of the opposite outer side surfaces of the housing body.

15 . The housing assembly according to claim 14 , wherein the locking lever is formed with an error-proofing stopper preventing the locking lever from being pivoted from the pre-locked position in a direction opposite to the locked position.

16 . The housing assembly according to claim 15 , wherein the error-proofing stopper extends from each arm portion of the pair of arm portions towards the outer side surface of the housing body.

17 . The housing assembly according to claim 1 , wherein the housing assembly is an outer housing of an electrical connector adapted to electrically connect connection to a battery of a vehicle.

18 . An electrical connector housing, comprising:
a housing, including:
at least one groove formed in a first outer side surface of the housing and adapted to receive an elastic protrusion of a locking lever pivotally mounted to the housing with the locking lever in a pre-locked position; and
at least one sliding groove formed in the first outer side surface of the housing and positioned adjacent to the at least one groove, the first sliding groove adapted to slidably receive the elastic protrusion of the locking lever as the locking lever is moved from the pre-locked position.

19 . The housing according to claim 18 , wherein:
the at least one groove includes a first groove formed in the first outer side surface of the housing and a second groove formed in a second outer side surface of the housing oppose the first outer side surface; and the at least one sliding groove includes a first sliding groove formed in the first outer side surface of the housing and a second sliding groove formed in the second outer side surface of the housing.

20 . The housing according to claim 18 , wherein the at least one groove is located directly adjacent to a first end of the at least one sliding groove in a direction of extension of the at least one sliding groove.
