Abstract

A first housing (10) is formed with guiding holes (24) through which a releasing member (27) is inserted while being held in contact therewith in a movable range between a standby area and a releasing position. In the process of connecting the first housing (10) and a second housing (40), the releasing member (27) comes into engagement with the second housing (40), thereby being displaced backward relative to the first housing (10). Since the first housing (10) is formed with the guiding holes (24) through which the releasing member (27) is inserted while being held in contact therewith, the releasing member (27) is smoothly moved without being displaced and being forced.

Claims

1. A connector for connection with a mating connector having a mating housing (40), mating terminals (42) in the mating housing (40) and a shorting terminal (43) for shorting the mating terminals (42), the connector comprising:

a housing (10) having a front end for connection with the mating housing (40), at least one guiding hole (24) extending through the housing (10) in a front to rear direction, at least one resilient piece (18) on the housing (10) and a restricting portion (22) formed on the resilient piece (18); and

a releasing member (27) having at least one unlocking piece (29) slidably engaged in the guiding hole (24) for guiding forward and rearward movement of the releasing member (27) relative to the housing (10), the releasing member (27) engaging the restricting portion (22) when the resilient piece (18) is in a first position for limiting forward movement of the releasing member (27) relative to the housing (10), the resilient piece (18) being deflected to a second position when the housing (10) is connected with the mating housing (40) for disengaging the releasing member (27) from the restricting portion (22) and permitting forward movement of the releasing member (27) relative to the housing (10), whereby the forward movement of the releasing member (27) enables the unlocking piece (29) to deflect the shorting terminal (43) away from the terminal fittings (42) for releasing a shorted state of the terminal fittings (42) when the housing (10) is connected properly with the mating housing (40).

2. The connector of claim 1, wherein the releasing member (27) is operable in a moving direction (MD) substantially parallel to a connecting direction (CD) of the housing (10) with the mating housing (40).

3. The connector of claim 1, wherein unlocking pieces (29) and the guiding holes (24) are dimensioned for preventing the releasing member (27) from being displaced in directions at an angle to a moving direction (MD) of the releasing member (27) relative to the housing (10).

4. The connector of claim 1, further comprising at least one first lock (31) and at least one second lock (32) formed on the releasing member (27) and being engageable with at least one window (20) of the housing (10) so that the resilient member (27) can be moved backward relative to the housing (10) without coming backward out of the housing (10).

5. The connector of claim 1, further comprising a locking piece (30) on the releasing member (27) for engaging the restricting portion (22) of the resilient piece (18) when the housing (10) is not yet connected with the mating housing (40) for holding the releasing member (27) in a standby area.

6. The connector of claim 5, wherein the resilient piece (18) is disposed to be engaged by the mating housing (40) in the process of connecting the housing (10) with the mating housing (40) and deformed resiliently to the second position for releasing an interlocked state of the resilient piece (18) and the locking piece (30).

7. The connector of claim 6, wherein the resilient piece (18) and the locking piece (30) are resiliently deformable in directions at an angle to interlocking directions of the resilient piece (18) and the locking piece (30).

8. The connector of claim 1, wherein the guiding hole (24) is substantially flat in cross-section.

9. The connector of claim 1, wherein a rear surface of the releasing member (27) is substantially flush with a rear surface of the housing (10) when the releasing member (27) is moved forward to a releasing position (RP).

10. A connector assembly, comprising:

a first housing (10) having opposite front and rear ends, first terminal fittings (14) mounted in the first housing (10), at least one resilient piece (18) projecting forward on the first housing (10) and a restricting portion (22) formed on the resilient piece (18);

a second housing (40) having a connecting recess (41) for receiving the first housing (10), second terminal fittings (42) projecting into the connecting recess (41) and being connectable with the first terminal fittings (14) when the first housing (10) is inserted into the connecting recess (41), a resiliently deflectable shorting terminal (43) mounted in the second housing (40) for shorting the second terminal fittings (42); and

a releasing member (27) mounted movably in the first housing (10) and having at least one forwardly projecting unlocking piece (29), the restricting portion (22) of the first housing (10) engaging the releasing member (27) and preventing forward movement of the releasing member (27) when the first housing (10) is not connected with the second housing (40), the restricting portion (22) being disengaged from the releasing member (27) when the first housing (10) is connected with the second housing (40) for permitting movement of the releasing member (27) into a position where the unlocking piece (29) deforms the shorting terminal (43) away from the second terminal fittings (42).

11. The connector assembly of claim 10, wherein the releasing member (27) is operable in a moving direction (MD) substantially parallel to a connecting direction (CD) of the first housing (10) with the second housing (40).

12. The connector assembly of claim 11, wherein unlocking pieces (29) and the guiding holes (24) are dimensioned for preventing the releasing member (27) from being displaced in directions at an angle to a moving direction (MD) of the releasing member (27) relative to the first housing (10).

13. The connector assembly of claim 12, wherein the guiding hole (24) is substantially flat in cross-section.

14. The connector assembly of claim 10, further comprising a locking piece (30) on the releasing member (27) for engaging the restricting portion (22) of the resilient piece (18) when the first housing (10) is not yet connected with the second housing (40) for holding the releasing member (27) in a standby area.

15.
