Abstract

A connector housing (20) includes a housing body (21) to which a mating connector housing is to be fit from front. A lock arm (40) has front and rear ends fixed to the housing body (21). A lock (42) is provided in a central part of the lock arm (40) in the front-rear direction and is configured to lock the mating connector housing. A pressing surface (43) is on a rear end part of the lock arm (40) and is configured to displace the lock (42) in an unlocking direction by being pressed. A coupling portion (44) couples the pressing surface (43) to the central part of the lock arm (40) in the front-rear direction.

Claims

1. A connector housing (20), comprising:

a housing body (21) having a front end to which a mating connector housing is to be fit;

a lock arm (40) having front and rear ends fixed to the housing body (21) and having a lock (42) in a central part in a front-rear direction, the lock (42) being configured to lock the mating connector housing;

a pressing surface (43) disposed on a rear end part of the lock arm (40), the pressing surface (43) being configured to displace the lock (42) in an unlocking direction by being pressed; and

a coupling portion (44) coupling the pressing surface (43) to the central part of the lock arm (40) in the front-rear direction.

2. The connector housing (20) of claim 1, wherein the coupling portion (44) includes two arms (49) coupled respectively to left and right sides of the lock arm (40), and the pressing surface (43) extends to the arm portions (49).

3. The connector housing (20) of claim 1, wherein the pressing surface (43) is formed with a cutout (52) configured to allow the rear end part of the lock arm (40) to escape when the pressing surface (43) is pressed.

4. The connector housing (20) of claim 1, wherein:

the housing body (21) includes a protecting portion (29) configured to cover a side of the lock arm (40) opposite to the unlocking direction in an intermediate part of the lock arm (40) in the front-rear direction; and

the pressing surface (43) is located behind the protecting portion.

5. A connector (C), comprising:

the connector housing (20) of claim 1; and

a terminal fitting (10) accommodated in the housing body (21).

6. The connector (C) of claim 5, wherein the terminal fitting (10) is a coaxial terminal (10) to be connected to an end of a coaxial cable.
