The present invention relates to a coupler that is releasable by operation of a press-fit means formed on the side of the female coupler in the engagement state between the engaging projection of the male coupler fitted into the female coupler and the engaging portion of the female coupler.

Conventionally, a so-called front release type that moves the male coupler approximately horizontally with respect to the female coupler, engages and couples the female coupler and the male coupler, and releases the coupling by vertical press-in operation. As the coupler, one of the snap coupler type shown in Figs. 18 and 19 is conventionally used.

In this coupler, the female coupler 100, which is generally mounted on the main body side K 'of the object to be mounted K, is looped to a substantially rectangular position in the longitudinal direction of the attachment substrate 102 having a substantially rectangular shape. The rectangular frame in which the mold 101 is erected and generally mounted on the cover side K of the object K to be mounted on the cover side K, with respect to the object K. And a plate-like engagement piece 202 connected to the side of the rectangular frame 201 that is inserted into the female engagement hole 100.

Then, an end portion 203 is formed at the tip of the engagement piece 202 of the male coupler 200, and the bending piece 202 is bent downward by inserting the engagement piece 202 into the annular frame 101. The engagement surface 204 formed at the end portion 203 is engaged with the side surface of the annular frame 101 by the elastic force to the upper side of the engagement piece 202 so that the female coupler 100 The coupler 200 is configured to couple.

By the way, in the conventional coupling tool such as the snap coupling tool type, the engaging piece 202 is fitted into the annular frame 101 of the female coupling member 100 by press-fitting downward to thereby engage the engaging piece ( The engagement surface 204 of 202 and the annular frame 101 are released. Therefore, in order to facilitate this operation, it is necessary to configure the engagement piece 202 with a size sufficient to carry out the operation, whereby the male engagement tool (fitted to the annular frame 101) is thereby formed. The dimensions of the engaging piece 202 and the rectangular frame 201 of the 200 cannot be reduced.

As a result, when the rectangular frame 201 of the male coupler 200 is pulled out of the annular frame 101 of the female coupler 100, as shown by a virtual line in FIG. The installation K of the cover side K on which the male coupler 200 is mounted is bent as much as the insertion depth of the rectangular mold 201 with respect to the mold 101. This bending causes the repelling force F of the mounted object K to be bent in the insertion direction with respect to the rectangular frame 201 to be pulled out, which causes the smooth removal of the rectangular frame 201. do.

In addition, since the force to exfoliate the to-be-attached object K in the said rectangular frame 201 is frequently applied to the mounting part of the said rectangular frame 201 and the lid side K of the to-be-adhered object K, With time, problems such as deterioration of the mounting state of the water coupler 200 and the object to be mounted K occur.

In addition, when removing the rectangular frame 201 of the male coupler 200 from the female coupler 100, the engagement piece 202 must be pulled out while pressing with a finger. There was a problem in that the 101 touched the finger, which hindered the operation of pressing it out.

On the other hand, in Korean Utility Model Publication No. 91-1037, it is known that the male coupler contained in the female coupler can be easily withdrawn in the withdrawal direction by the operation of the press-fit means.

However, according to this conventional structure, since the coupling part of the male and female is exposed to the outside, the object and the human body are often damaged when they are in contact with another object or the human body.

In addition, there is a closed end such that the engaged state is released by touching another object by an unexpected operation.

However, the pair of engaging projections 25 and 25 are formed to be inwardly engaging projections, and the female coupling The shape of the recessed part 12g, the protrusion 12f, etc. of the engagement member 12 of the sphere 10 may be changed and comprised.

The engaging tool (T) according to the present invention is the engaging portion and the male coupling tool of the engaging member 12 of the pressure coupling tool 10 by the operation of the pressing means formed in the female coupling tool (10). Since the engaged state of the engaging protrusion 25 of the 20 can be released, and the female engaging tool 10 and the male engaging device 20 which are engaged and engaged by this can be detached, Some dimensions of the male coupler 20 including the engaging projection 25 fitted into the female coupler 10 can be made as small as possible.

Therefore, when the male coupler 20 is pulled out of the female coupler 10, since the dimension for moving the male coupler 20 in the horizontal direction can be reduced, the male coupler 20 is mounted. The warpage of the object K can be reduced. As a result, since the repulsive force of the to-be-adhered object K which tries to return the said male coupling tool 20 to an insertion direction by the cause of curvature as mentioned above can be reduced, the removal of the male coupling tool 20 is carried out. You can do it smoothly.

In addition, the object K is to be peeled from the male coupling tool 20 which is applied to the mounting portion between the male coupling tool 20 and the mounted object K, which frequently occurs due to the cause of the bending. Since the force can be reduced, it is possible to stably maintain the mounting state of the male coupler 20 and the object to be mounted (K).

In addition, when removing the male coupler 20 from the female coupler 10, only the pressing means of the female coupler 10 needs to be operated. It has a feature that can constitute a coupler (T).
