[Problems to be Solved by the Invention] As shown in FIG.
In the grommet with the connector configured as described above, the connection between the connectors is likely to be incomplete as the number of connectors increases, and since the connection portion is covered by the grommet 60, it is determined whether the connectors 40 and 50 are completely connected. Is extremely difficult to determine.

Further, the composite connector disclosed in the above-mentioned utility model application publication is disclosed.
The connector cannot detect incomplete mating between connectors.
The connector disclosed in the above utility model application has a connector
After performing the first fitting operation, push the lock detection component.
Connector operation.
Confirmation operation is not quick and the lock detection parts are assembled.
There is a problem that the configuration of the connector to be inserted becomes complicated.

The present invention solves the above-mentioned problem, and can easily detect incomplete connection between both connectors to be connected.
An object of the present invention is to provide a connector device with a grommet .

[0008]

Means for Solving the Problems] The grommet connector device with the present invention for solving the problems of, providing a locking projection 5 which fits locking the engaging slot a vehicle panel A to the tip
And a connector securing the locking piece 4, engaging the connector 1 and the engaging projection 3 provided in the opening edge of the abutment 2 fit for mating connector to lock the locking projection 3 of the connector <br/> Kuta 1 The other connector 10 provided with a locking piece 11 provided with a projection 12 so as to be vertically movable;
Projecting from the inner side of the abutment 21 fitting connector detection key 22 to be inserted into the lower gap of the locking piece 11 of the connector 10
An inner 20 and a grommet fitted to the inner 20
And 30 are provided .

[0009]

A connector provided on one connector 1 to be connected
The locking projection 5 of the distal end portion of the mounting engagement pieces 4 forcibly fitted engagement locked in <br/> engaging slot a vehicle panel A mounting the connector 1 to the vehicle panel A. Then, by fitting the distal end portion of the mating connector 10 into the fitting opening 2 of the connector 1 counterparty
The locking projection 12 of the locking piece 11 of the connector 10 is
The fitting is engaged with the engaging projection 3 of the abutment 2 of the connector 1,
10 are electrically connected to each other. Next , the Grommet
The inner 20 to which the connector 30 is fitted is fitted to the connector 10.
The grommet 30 is pressed into contact with the peripheral surface of the grommet 30 against the vehicle panel A to prevent rainwater, dust and the like from entering the vehicle interior.

When the connectors 1 and 10 are completely connected to each other
Are the locking projections of the mating opening 2 for the mating connector of the connector 1
3, a locking projection 12 of a locking piece 11 of a mating connector 10;
Is locked, and the locking piece 11 is below its lower surface without bending downward.
Since a gap is formed on the side of the connector 10,
-20, the connector of the inner 20 is inserted into the gap.
The tip of the detection key 22 protruding into the fitting opening 21 is fitted.
And the inner 20 is completely inserted into the connector 10.
Be in a state. In this state, the connectors 1 and 10 are completely connected.
The connection is detected.

If the connectors 1 and 10 are incompletely connected to each other, the mating connector 2
The locking projection 12 of the locking piece 11 of the mating connector 10 does not lock to the locking projection 3 of the mating connector 10, and the locking piece 11 is bent downward. For this reason, the inner to the mating connector 10
Even if it is attempted to insert the connector 20, the tip surface of the detection key 22 projecting into the connector fitting port 21 of the inner 20 abuts on the free end surface of the locking piece 11, and the inner 20 is connected to the connector 10. Into a state where it cannot be inserted . In this state
As a result , incomplete connection between the connectors 1 and 10 is detected.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a fragmentary exploded view showing an embodiment of the present invention.
One of the connector 1 is to be connected in FIG, 2 is fitted to the distal end portion of the counterpart connector 10 to be described later counterpart connector
The connector fitting opening 3 is a locking projection provided at the center of the upper edge of the fitting opening 2, and the connector mounting locking pieces 4 and 4 are supported at the base end of the connector 1 so as to be vertically movable and project forward. In the connection
The connector 1 is mounted on the vehicle panel A by forcibly fitting and locking the locking projections 5 provided at the tips of the locking pieces 4, 4 on the vehicle panel A with the locking openings a provided on the vehicle panel A. ing.

[0013] 10 of the other party to be electrically connected to the connector 1 connector, 11 is a locking piece which is vertically movably supported on the distal end central portion of the upper surface of the mating connector 10, the connector in the locking piece 11 locking projection 12 for locking is projectingly provided on one <br/> locking projections 3 of the mating connector fitting for abutment 2.

Reference numeral 20 denotes a resin inner fitting fitted to a rubber grommet 30 , and the connector 10 is fitted on the front surface thereof.
A mating connector fitting port 21 is provided, and a detection key 22 that is inserted into the lower surface of the locking piece 11 provided on the connector 10 protrudes inside the connector fitting port 21.

[0015] The grommet of the present invention configured as described above.
The attached connector device, for example, to connect the harness arranged in the harness and the passenger compartment disposed in the engine room side, as shown in FIG. 2, the tip of the locking piece of the connector 1 4,4 The connector 1 is attached to the vehicle panel A by forcibly fitting and locking the locking projection 5 of the vehicle 1 into the locking opening a of the vehicle panel A.

[0016] Subsequently, the connector 1 of the mating connector
Tip Mate the mating connector 10 in use the fitting opening 2, forcibly engaged the locking projections 12 of the locking piece 11 of the mating connector 10 to the locking projection 3 of the fitting opening 2, both The connectors 1 and 10 are electrically connected.

[0017] Next, fitted a resin inner 20 which is fitted a rubber grommet 30 to the connector 10, the front end peripheral surface of the grommet 30 is pressed against the vehicle panel A, rainwater into the car, invasion of dust or the like To prevent

When the connectors 1 and 10 are incompletely connected, as shown in FIG. 3, a locking projection 3 of a fitting opening 2 of the connector 1 and a locking member provided on a mating connector 10 so as to be vertically movable. a locking projection 12 projecting from the strip 11 is not locked, the locking piece 11 is in a state flexed downwardly. Thus, even so fitted to the inner 20 to the connector 10, the detection key projecting from the connector fitting opening 21 within the side of Lee runner <br/> -20 2
Since the distal end surface of the inner member 20 comes into contact with the free end surface of the locking piece 11 of the connector 10, the inner 20 cannot be fitted into the connector 10. In this state
The connector 1,10 mutual incomplete connection can be surely detected more during the connection work.

When the connectors 1 and 10 are completely connected to each other
The locking piece 11 of the connector 10 does not bend downward.
A gap is formed below the spider, and the inner
Since the tip of the detection key 22 of FIG.
The complete connection between the connectors 1 and 10 is confirmed.

[0020]

[Effects of the Invention] As described above, the present invention locks the connector.
Insert the detection key into the connector
Fit the inner protruding inside the grommet to the grommet,
Grommet fitting inner provided separately from the connector,
Mating connector connected to the connector mounted on the panel
The inner is connected to the connector.
By simply inserting the connector into the connector
Complete and incomplete connection can be reliably detected.
And complicated like the push-in operation of the conventional lock detection part.
Easy, quick and incomplete connection during connection work without any need for complicated operations
Can be detected to prevent an electrical accident.
