In the fitted state, the fitting portion 210 of the male housing 20 fits into the fitting space 311 of the female housing 30 and the tip end abuts on the contact surface 50a of the elastic member 5, as shown in FIG.

<Release of mating state>
To release the mated state of the male connector 2 and the female connector 3, as shown in FIG. 7, the locked state of the hook portion 203 of the lock arm 201 and the locked portion 313a of the lock locking portion 313 is released. It is performed in a releaseable state. To release the locked state between the hook portion 203 of the lock arm 201 and the locking portion 313a of the lock locking portion 313, the male connector 2 was moved in the direction (fitting direction) of the female connector 3 and brought into contact with each other. The locking surfaces 205 and 315 are moved away from each other. As shown in FIG. 7, this moving distance is larger than the release regulation distance by the taper provided on the locking surfaces 205 and 315, and the concave portion 206 and the convex portion 316 provided on the locking surfaces 205 and 315 It is a distance equivalent to the release regulation distance required to loosen the fit.

As shown in FIG. 7, when the locking surfaces 205 and 315 are moved by a distance corresponding to the release regulation distance between the concave portion 206 and the convex portion 316, the lock arm 201 and the lock locking portion 313 The lock can be released, and the lock arm 201 is released. By the release operation, the operation portion 207 provided at the tip end portion of the lock arm 201 is lowered downward, and the hook portion 203 is released from the locked state of the locking portion 313a. In this way, the locked state of the lock arm 201 and the lock locking portion 313 is released, and the fitted state of the connector structure 1 can be released.

As described above, in order to release the locked state, the male connector 2 must be moved in the direction of the female connector 3, that is, the fitting direction, but as shown in FIG. 4, the male connector 2 is fitted in the fitted state. The joint portion 210 fits in the fitting space 311 and the tip portion is in contact with the contact surface 50a of the elastic member 5. When the fitting portion 210 in this state is pushed further to the back, the restoring force due to the deformation of the elastic member 5 acts in the opposite direction (anti-fitting direction), so that the male connector 2 is directed toward the female connector 3. Movement will be restricted.

In this way, in order to release the fitted state, the lock arm 201 must be pushed down to release the locked state, but for that purpose, the male connector 2 already in the fitted state is used as the restoring force of the elastic member 5. It must be moved further in the fitting direction against it, and requires a force higher than the normal fitting force. Further, the components of the force at this time are the force in the fitting direction and the force in the direction of pushing down the lock arm 201, and the directions of these two forces are orthogonal to each other and cannot be carelessly generated at the same time. As a result, the connector structure 1 in which the locked state of the lock arm 201 and the lock locking portion 313 is hard to be released and the fitted state is hard to be released can be obtained.

<Effect>
The locking surface 205 of the hook portion 203 of the lock arm 201 and the locking surface 315 of the locking portion 313a of the lock locking portion 313 are provided with a taper in a direction for restricting the release of the locked state. A connector structure 1 is obtained in which the locked state is not easily released even when a prepared force is applied.
-Since the locking surface 205 of the hook portion 203 is provided with the concave portion 206 and the locking surface 315 of the locking portion 313a is provided with the convex portion 316, it is difficult to release the locked state even if an inadvertent force is applied. The connector structure 1 is obtained.

In the fitted state, the tip of the fitting portion 210 is in contact with the elastic member 1 at the back of the fitting space 311. As a result, when the fitting portion 210 is further pushed to release the locked state, a force acts in a direction for restricting the release of the locked state. As a result, a connector structure 1 is obtained in which the locked state is not easily released even if a force is carelessly applied.
A force in the mating direction and a force in the direction of pushing down the lock arm 201 are required to release the mating state, but since these two forces are orthogonal to each other, they cannot be generated at the same time almost carelessly. .. As a result, the connector structure 1 in which the locked state is not easily released can be obtained.

<Other embodiments>
FIG. 8 is a connector structure according to another embodiment of the present invention, in which (1) is a cross-sectional view of a main part, (2) is an elastic member, and (3) is a holder.

An elastic member 5'is provided at the back of the fitting space 311. The elastic member 5'includes a hollow tubular main body 50'and a lip 51 extending in an annular shape on the peripheral surface. The elastic member 5'is mounted in a state where the tip of the lip 51 is crushed and the rear surface contact portion 50'b is in contact with the inner portion of the fitting space 311.

The fitting space 311 includes a tubular holder 6 inside. The holder 6 is a tubular body, and the total length is shorter than the axial dimension of the fitting space 311. Further, the holder 6 is shorter than the axial dimension of the fitting portion 210.

The outer peripheral surface of the holder 6 mounted in the fitting space 311 has a clearance with the inner peripheral surface of the fitting space 311. The holder 6 can move in the fitting space 311 along the axial direction. Further, the inner peripheral surface of the holder 6 is formed of a flat surface, and the fitting portion 210 can insert the inner hollow portion.

The holder 6 mounted on the fitting space 311 can move along the axial direction in the fitting space 311. In the male connector 2, the pressing portion 208 of the main body portion 200 comes into contact with the front contact portion 62 of the holder 6 in the middle of fitting. As a result, in the latter half of the fitting process, the holder 6 moves integrally with the fitting portion 210 in the fitting direction. The lock arm 201 is locked to the lock locking portion 313 in the process in which the tip portion of the fitting portion 210 passes through the inside of the elastic member 5'. At this time, the locking surface 205 of the hook portion 203 and the locking surface 315 of the locking portion 313a come into contact with each other, and the concave portion 206 of the hook portion 203 and the convex portion 316 of the locking portion 313a fit into each other. As a result, the lock arm 201 and the lock locking portion 313 are locked. When in the locked state, the male connector 2 and the female connector 3 are in the fitted state. Further, in the locked state, the tip end portion of the holder 6 is in contact with the front contact portion 50'a of the elastic member 5'.

In order to release the mated state, the male connector must be moved in the direction of the female connector to release the locked state. At this time, since the elastic member 5'is deformed via the holder 6, the required restoring force can be obtained without increasing the size of the connector structure 1, so that the lock arm can be obtained even when an inadvertent force is applied. A connector structure is obtained in which the locked state between the lock hole and the lock hole is difficult to be released. Even when the configuration is changed in this way, the above-mentioned effects can be generally obtained.
