Mating connector 2 having movable cover 250
At 01, the mating portion 207 of the mating insulator 203 is made to face the mating portion 107 of the insulator 103. When the mating portion 107 and the mating mating portion 207 are opposed to each other so as to match with each other, the engaging protrusions 115a and 116
a is pushed outward so as to ride on the outer surface of the pair of spring holding cylinders 261 and 262 of the movable cover 250 located on both sides of the opening 205a.
The tips of 15, 116 abut.

Next, when the mating insulator 203 is further moved in the fitting direction I, as shown in FIGS.
The mating part 207 is fitted to the mating part 7. At this time, the engagement piece 11
The engagement protrusions 115a and 116a of the pair 5 and 116 slide on the pair of mating side walls 211 and 212 to engage the engagement grooves 211a and 211a.
2a. In this state, the connector 101 and the mating connector 202 are completely fitted. When the engagement protrusions 115a and 116a of the engagement pieces 115 and 116 engage with the engagement grooves 211a and 212a, the pair of spring holding cylinders 261 and 262 of the movable cover 250 abut against the outer surfaces of the pair of spring holding cylinders 261 and 262. Since the tips of the engagement pieces 115 and 116 return to the original state, the abutting state is released, so that the coil spring 265 in the movable cover 250 extends to move the movable cover 25.
0 is moved to the fitting portion 107 side. At this time, the contact portion 105a of the contact 105 and the mating contact portion 205a of the mating contact 205 are completely in contact with each other.

By the way, the mating part 207 is
When the fitting operation is interrupted during the fitting with the contact 105, the contact portion 105 a of the contact 105 and the mating contact 205
Is slightly in contact with the other party contact portion 205a. At this time, the mating fitting portion 207 and the fitting portion 107 are not completely fitted, but are fitted with a small fitting size. In the following description, this state is called a half-fitted state. . In the half-fitted state, the contact portion 105 of the contact 105
a and the mating contact portion 205a of the mating contact 205 are also in incomplete contact.

When the fitting operation is interrupted in this half-fitted state,
A pair of spring holding cylinder portions 261 and 262 of the movable cover 250
Since the tips of the pair of engagement pieces 115 and 116 abut against the outer surfaces of the pair, the slightly compressed coil spring 265 expands, and the half-fitted state between the mating fitting portion 207 and the fitting portion 107 is released. Then, the mating connector 202 moves in the detaching direction from the connector 101 and detaches.

Therefore, in this connector device, the semi-fitted state between the connector 101 and the mating connector 201 is determined by the movable cover 250, the coil spring spring 265, and the engaging piece 11
5 and 116 to avoid the problem.

[0019]

However, in the conventional connector device, the connector 102 and the mating connector 20 are not provided.
1 is avoided by the configuration of the components such as the movable cover 250, the coil spring 265, and the pair of engagement pieces 115 and 116, so that the number of components is increased and the configuration is increased. However, there is a problem that it becomes complicated and the assembly work takes time.

Due to the configuration using 15 and 116, there is a problem that due to these deformations and reduced functions, it is not possible to reliably prevent the half-fitting.

Further, in a harness operation of an automobile, a connector must be fitted to a mating connector at a lower portion or a deep portion of a front panel, and a connector must be fitted to the mating connector by groping in a deep portion. This is a difficult task.

In the fitting operation in such a place, the engaging protrusions 115a, 116a are inserted into the engaging grooves 211a, 212a.
If the fitting operation is performed only with the sense of a finger, the work will not be complete unless the mating part is completely pushed into the mating part until the mating part is completely inserted. It will be difficult.

Therefore, an object of the present invention is to prevent the connector and the mating connector from being left in a half-fitted state, and even in the half-fitted state, both the repulsive force and the inertia force are maintained. It is an object of the present invention to provide a connector device that can be moved to a position where a connector and a mating connector are completely fitted and brought into a completely fitted state.

Still another object of the present invention is to provide a connector device capable of reducing the number of parts, facilitating the work of the fitting / removing operation, and obtaining a highly reliable completely fitted state. It is in.

Meshes with the tooth portion 41a. In this state, when the fitting operation is further advanced, as shown in FIG.
Rotates clockwise as shown by the arrow. At this time, the spiral spring member 45 is compressed and its winding diameter is reduced, so that a repulsive force is generated. That is, since the spiral spring member 45 has a repulsive force, the connector 1 is connected to the mating portion 37 of the mating connector 30.
The force is acting in the direction of pushing in the direction II.

As described above, the first rack portion 15 and the gear 4

If the operation of fitting the connector 1 to the mating connector 30 is interrupted in the first half of the fitting, that is, if the fitting operation is stopped due to an illusion that the connector 1 is completely fitted, the spiral is used. Since the repulsive force of the spring member 45 acts in the detaching direction II for detaching the connector 1 from the mating connector 30, the connector 1 comes off from the mating connector 30, so that the connector 1 is returned to a completely unfit state. Can be.

Further, in the fitting operation, the fitting operation is interrupted immediately after the point A has been exceeded, that is, at the time when the fitting part 7 has crossed the boundary of the point A in the middle of the engagement with the mating part 37. In this case, since the connector 1 is advanced in the fitting direction I by the repulsive force of the spiral spring member 45 at this time, the connector 1
The connector and the mating connector 30 move to a position where they are completely fitted, and are completely fitted.

In the embodiment, the first and second rack portions 1 are provided in each of the pair of guide grooves 13.

At this time, a key member for guiding the connector 1 may be provided in the other guide wall portion 13 in the other side wall portion 37c.

[0056]

As described above, according to the connector device of the present invention, according to the connector device of the present invention, the gear and the spiral spring member provided on the connector and the first and second rack portions provided on the mating connector are used. The connector and the mating connector are configured so that the connector and the mating connector repel each other toward or away from the mating side at the middle point of the mating and unmating due to the repulsive force of the spiral spring member. Can be prevented from remaining in a half-fitted state.

Further, in the fitting operation, the fitting is performed immediately after the intermediate point is exceeded, that is, at the time when the state of meshing between the first rack portion and the tooth portion is shifted to the meshing state of the second rack portion and the tooth portion. When the operation is interrupted, since the direction of the repulsive force of the spiral spring member at this point is the fitting direction, the connector can be moved to a position where the connector is completely fitted.

Further, a gear having a small shape is provided on the mating connector, and a half-engaged state can be prevented only by meshing with the rack portion. Even if the fitting operation is interrupted at a position beyond an intermediate point during the fitting operation, the fitting is stopped.
