[Detailed description of the device] [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-touch detachable connector in which a male and a female connector are fitted to each other so that the fitting can be released by a one-touch operation.

[Prior art]

Conventionally, as a connector, there is a connector of a type in which a male and a female are fitted. It is possible to energize by mating a male connector with a male contact on the connector housing and a female connector with a female contact on the connector housing to bring the male and female contacts into contact. It is a connector that puts it in a proper state. However, if the fitting is unintentionally disengaged, the power supply is cut off at an unexpected time. Therefore, a lock is provided so as not to be easily separated. For example, Japanese Utility Model Laid-Open No. 56-77 is known as a document relating to a male / female fitting type connector with a lock.

[Problems to be solved by the device]

(Problem) However, the above-mentioned conventional connector requires a considerable amount of force and time to separate the mated female side connector and male side connector, and repairs equipment equipped with many connectors. When checking, there was a problem that workability was poor. (Explanation of Problems) In the male-female fitting type connector, in order to make good electrical contact, the contacts are brought into sliding contact with each other with a certain frictional force. Further, in order to prevent the contacts from rattling with each other, the contact housings are also fitted to each other exactly without any extra gap. Therefore, when fitting and disengaging, it is necessary to overcome the frictional force between the contact housings. Therefore, when fitting or disengaging, it is necessary to add a force that overcomes the total frictional force between the contacts and between the connector housings. In view of the above problems, it is an object of the present invention to eliminate the need for a person to apply the above-mentioned force when detaching, and to enable instant detachment with one-touch operation. is there.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, in the one-touch disconnection type connector of the present invention, a male side connector having at least a releasing spring compressed by a female side connector at the time of fitting and a lock rod having a locking action at the time of completion of fitting is pressed. Therefore, it is configured to include a female connector having at least a piston for releasing the lock with the lock rod.

[Action]

The fitting of the connector is performed by applying a force against the frictional force between the contacts and between the contact housings and the elastic force of the detaching spring. Then, when the fitting is completed, the lock bar engages with the female side housing and is locked. The fitting is released by pressing the piston. The lock is released when the piston is pressed. Then, the force for releasing the fitting is satisfied by the elastic force of the compressed release spring, and it is not necessary for a person to apply force. Therefore, the connector can be detached by only one-touch operation of pressing the piston.

FIG. 3 shows the one-touch detachable connector in a fitted state. The reference numerals correspond to those in FIGS. 1 and 2. The lock rod 13 is erected from the bottom of the male housing 11, and the lock rod tip portion 13-1 has a taper portion extending outward from the tip end and a step portion for locking engagement on the back. . One end (right side) of the detaching spring 14 is fixed to the male housing 11 by a detaching spring stopper 11-1. The other end is a free end. The locking edge portion 2-2 may be a donut-shaped plate fixed to the female side housing 2 after the lock releasing recess 5-4 is housed in the sliding body housing chamber 7. The pressing plate 5-1 is fixed to the neck portion 5-2 connected to the sliding body 5-3 and constitutes a part of the piston 5. Sliding body 5-3
Is slid by operating the pressing plate 5-1. Now, the fitting is performed as follows. So that the lock bar 13 is inserted into the fitting opening 6,
The male side connector 10 and the female side connector 1 are opposed to each other so that the male contact portion 12 is inserted into the female contact portion 4-3, and both are brought close to each other. In order to bring them close to each other, it is necessary to overcome the total frictional force between the outer wall of the female housing 2 and the inner wall of the male housing 11 and the frictional force between the male contact portion 12 and the female contact portion 4-3. During fitting, the male contact contact part 12-1
It advances while slidingly contacting the inner wall of the female contact portion 4-3.
As the fitting progresses, the tip of the detaching spring 14 comes into contact with the detaching spring stopper 2-3. After that,
It is necessary to add a force that overcomes the elastic force of the release spring 14. Then, as the approaching is continued, the outside of the lock rod tip portion 13-1 comes into contact with the locking edge portion 2-2 before long.
Both of them constitute a lock part. When it gets closer, locking is performed. FIG. 5 is a diagram for explaining the movement of the lock portion when fitting. FIG. 5B shows a state in which the lock rod 13 has advanced and the outside of the lock rod tip portion 13-1 is in contact with the locking edge portion 2-2. When the lock bar 13 further advances in the direction of the arrow, the state shown in FIG. FIG. 5A shows a state in which the lock rod tip portion 13-1 completely enters the sliding body accommodating chamber 7 and is locked. Locking is performed by engaging the back portion of the lock rod tip portion 13-1 with the back portion of the locking edge portion 2-2. Release spring 14 while locked
Is kept compressed. FIG. 3 is an overall image when this state is reached. The back of the lock rod tip 13-1 and the back of the locking edge 2-2 are rounded so that the lock can be released smoothly. The operation of releasing the fitted connector will be described below. In FIG. 3, the pressing plate 5-1 of the piston 5 is pushed to the right. Then, the sliding body 5-3 slides to the right, the lock releasing recess 5-4 contacts the lock rod tip portion 13-1, and the lock is released. FIG. 6 is a diagram for explaining the unlocking operation. When the sliding body 5-3 advances as shown by the arrow A and the lock releasing recess 5-4 comes into contact with the lock rod tip 13-1, the two lock rod tips 13-1 are unlocked. The recesses 5-4 are guided by the V-shaped taper and are brought close to each other. As a result, the engagement with the locking edge portion 2-2 is released (this engagement performed the locking action). Then
The releasing spring 14 which has been kept in the compressed state by this engagement is released from the compressed state.
The release spring 14 is a release spring stopper 2-
3 tries to return to the original state by kicking 3, but due to the elastic force at that time, the male side housing 11 becomes the female side housing 2
Will be more withdrawn. That is, the connector can be disengaged instantly by a one-touch operation of pressing the pressing plate 5-1 and without the need for a person to apply a disengagement force. FIG. 4 is an external view of the one-touch detachable connector in a fitted state. The reference numerals correspond to those in FIG. The spring 16 for returning the pressing plate may or may not be attached. If attached, push the push plate 5-1 to unlock and then push the push plate 5-1 by hand.
