ものを代替することができる。FIG. 1 shows a state in which the male housing 1 and the female housing 2 are separated from each other, and illustrations of connection terminals housed inside and electric wires connected to these connection terminals are omitted. When the male housing 1 is inserted into the female housing 2, the outer surface of the male housing 1 and the inner surface of the female housing 2 are respectively provided as first locking means that are naturally engaged. Locking portions 3a and 3b are provided. To release the first locking means, the pressing portion 4
By pressing, the engaging portions 3a and 3b can be disengaged from each other.
However, such a first locking means has been widely used in the past, and various types other than the illustrated example can be substituted.

通することができるようになっている。In order to detect whether or not the first locking means is correctly engaged and to ensure the locked state, in the embodiment, the female housing 2 and the thin hinge portion 5 that can be bent are used.
There is provided a second locking means 6 connected by. A protrusion 7 is formed on the second locking means 6, and when the second locking means 6 is tumbled around the hinge portion 5 in the female housing 2 as shown by an arrow A, the protrusion 7 is formed. A through hole 8 penetrating therethrough is provided. On the other hand, male housing 1
A through hole 9 which is matched with the through hole 8 in the normal locked state.
Is provided. The projecting body 7 has two through holes 8,
The through holes 8 and 9 can be penetrated only when the male housing 1 and the female housing 2 are properly fitted with each other, that is, when the male housing 1 and the female housing 2 are correctly fitted.

接続端子11に接触させるようになっている。In order to electrically check this connection state, as shown in FIG. 2, inside the female housing 2, a check electric contact piece 10 is provided at a position corresponding to the lower side of the through hole 8 and the through hole 8 is provided. The check electrical contact piece 10 is pushed down by the tip of the projecting body 7 penetrating 8 and 9, and is brought into contact with a part of the connection terminals 11 as shown in FIG.

気的にチェックすることが可能となる。In the state where the projecting body 7 is not fitted into the through holes 8 and 9, the checking electrical contact piece 10 is separated from the connecting terminal 11 as shown in FIG. 2, but the male housing 1 is replaced by the female housing 2. Only when the through hole 8 and the through hole 9 are correctly fitted and the projecting body 7 is inserted therein, the checking electrical contact piece 10 is pressed by the projecting body 7 and comes into contact with the connection terminal 11. Therefore, if the electrical detector 12 as shown in FIG. 2 is connected between the checking electrical contact piece 10 and the connection terminal 11, it can be determined whether the male housing 1 and the female housing 2 are properly fitted. It becomes possible to electrically check.

ができる。Further, the second locking means 6 which fits the projecting body 7 into the matched through holes 8 and 9 causes double locking together with the first locking means described above. Less rattling between the housing 1 and the female housing 2,
A strong locked state can be maintained even against vibration and shock.
なお、ロック状態において、突体７が通し孔８、９から
容易に抜け出さないような適当な抜け止めを施すことが
望ましい。実施例では、第２のロック手段６に凸部6aを
設け、この凸部6aを通し孔８の周辺部2aの内側に引っ掛

In the embodiment, the second locking means 6 is provided with the convex portion 6a, and the convex portion 6a is hooked inside the peripheral portion 2a of the through hole 8 so that the projecting body 7 does not easily come out.

にしてもよい。Further, in the above-mentioned embodiment, the case where the second locking means 6 is formed integrally with the female housing 2 is shown, but it is not always necessary to form the second locking means 6 integrally. In short, as long as it has the protrusion 7 that can press the check electrical contact piece 10 through the through holes 8 and 9 and that the protrusion 7 does not easily come out from the through holes 8 and 9, The locking means 6 of 2 is the female housing 2
There is no problem even if it is separate from. Further, although the check by the electric contact piece 10 is mainly performed at the time of assembling the harness, it may be checked at a proper time during the use of the connector.

It is possible to prevent an accident due to a state of health. If other locking means is present in addition to this locking means, the lock is doubly reinforced so that it is resistant to vibrations and shocks and the rattling of both housings is reduced. The reliability of can be improved.
