Abstract

An electrical connector that can prevent an unexpected length of time from being spent in separating the mated connectors is provided. The supporting portion is a plate-like member forming a slot in which a jig can be inserted in cooperation with the operation portion when the plug housing and receptacle housing are mated, and serves as the fulcrum point of leverage while the jig inserted in the slot and working as a lever abuts against the operation portion and deforms the elastic portion so as to disengage the latching portion and engaging portion.

First claim

What is claimed is:

1. An electrical connector, comprising:
a first connector comprising a first housing forming an internal region with an insulation wall, and first contacts that are conductive members extending from the wall of the internal region toward the outside of the first housing; and
a second connector comprising a second housing comprising an insulating wall that is placed at least in part within the internal region of the first housing, and second contacts that are conductive members extending from the wall of the second housing toward the outside of the second housing,
in which the first contacts and the second contacts are electrically connected when the first housing and the second housing are mated,
wherein one of the first connector or the second connector comprises:
a latching portion positioned to face the wall of the housing of the other connector when the housing of one connector and the housing of the other connector are mated;
an operation portion extending outward from one connector and connected to one end of the latching portion; and
an elastic portion comprising a flexible member that is connected to the other end of the latching portion and mounted on the wall of the housing of one connector, and
the other connector comprises:
an engaging portion provided on the wall of the housing of the other connector facing the latching portion when the housing of one connector and the housing of the other connector are mated for engaging with the latching portion; and
a supporting portion that is a plate-like member forming a slot into which a jig can be inserted in cooperation with the operation portion when the housing of one connector and the housing of the other connector are mated and serving as the fulcrum point of leverage while the jig inserted in the slot and working as a lever abuts against the operation portion therefor deforming the elastic portion so as to disengage the latching portion and engaging portion from each other.

2. The electrical connector according to claim 1 , wherein
the other connector comprises a protective portion connected continuously to the supporting portion within the slot and extending toward the operation portion for protecting the other members from being damaged by contacting with the jig working as a lever.

3. The electrical connector according to claim 1 , wherein
the other connector comprises a reinforcing portion that is a plate-like member connected continuously to the supporting portion outside the slot and reinforces the supporting portion for improving the rigidity of the supporting portion.

4. The electrical connector according to claim 1 , wherein
the latching portion abuts against the wall of the housing of one connector to limit the deformation of the elastic portion when the elastic portion deforms under the leverage of the jig.

5. The electrical connector according to claim 1 , wherein
the latching portion comprises a latching piece in the shape of a protrusion,
the engaging portion is a plate-like member provided with an engaging hole for engaging with the latching piece, and
the latching piece abuts against the plate-like surface of the engaging portion and deforms the elastic portion when the housing of one connector and the housing of the other connector are mated and the latching piece is not engaged with the engaging hole so as to change the position of the operation portion and enlarge the slot compared with when the latching piece is engaged with the engaging hole.

6. The electrical connector according to claim 1 , wherein
the engaging portion and the supporting portion are formed by a sheet of plate, and
the engaging portion is fastened to the wall of the housing of the other connector.

7. The electrical connector according to claim 1 , wherein
one connector comprises at least two of the elastic portions, the latching portions, and the operation portions at opposite positions, and
the other connector comprises at least two of the engaging portions and the supporting portions at opposite positions.
