Abstract

The present invention is a connecting piece comprising a plug (12) and a socket (14), the plug (12) and the socket (14) are set to be able to connect and disconnect each other, and each has a mounting part for mounting to other components ( 28a, 38). The connector has a protruding portion (22) protruding from a base portion (16) of the plug (12) and an engaging portion (24) formed on the protruding portion (22). The socket (14) has a housing portion (32) for housing the protruding portion (22), and an engaged portion (34) formed on the housing portion (32) to engage the engaging portion (24). The plug (12) or socket (14) has an operation piece (26) for disengaging the engagement between the engaging portion (24) and the engaged portion (34). A first elastic deformation part (23) and a second elastic deformation part (25) are provided on the protruding part (22). Elastic deformation, the second elastic deformation part (25) is formed at a position different from that of the first elastic deformation part (23), when the plug (12) is connected to the socket (14), when the plug (12 ) and the socket (14) are separated from each other by a load, the second elastic deformation portion (25) can release the engagement between the engaging portion (24) and the engaged portion (34) under a load above a specified value. Elastic deformation in the way of engagement.

Description

technical field [0001] The present invention relates to a fastener such as a buckle that includes a male member and a female member and is capable of being connected to and released from each other. Background technique [0002] Conventionally, a buckle has been used as a coupling tool for detachably coupling two coupling objects such as ends of string-like members. The buckle includes a plug as a male member and a receptacle as a female member into which the plug is inserted and engaged. The plug includes a plug body and a pair of legs formed at both sides of the plug body parallel to each other. An operation piece and an engaging portion are respectively formed at the tip portion of each leg. The socket includes a socket body and an insertion hole formed in the socket body and into which a plug is inserted. In the insertion hole, there is formed an abutting portion that abuts against the legs and elastically displaces each leg inward, and an engaged portion for engaging...

Problems solved by technology

Therefore, when setting the pull-out force when the engagement is released as a relatively strong force to a certain extent, it is necessary to set the inclination angle of the abutment surface of the engaging part and the engaged part at the contact position to be the same as the pull-out force. The pulling direction is close to a right angle. In the case of this structure, the elastic deformation of the leg is difficult to proceed smoothly, and the engaging part of the leg and the engaged part of the socket may be damaged when the engagement is released. can no longer be used

[0011] In addition, in the coupling disclosed in Patent Document 2, when the coupling is partially broken, the coupling cannot be used again, and when the coupling is configured to be disengaged by a force greater than a predetermined value , there is the same problem as the above-mentioned patent document 1

Moreover, for the structure that can release the holding of the connecting part by receiving a force of more than a predetermined value, a holding structure and a holding release mechanism are required. In order to release the holding with a force of a predetermined value, a complicated and high-precision mechanism is required on a small member, resulting in the failure of the member. cost increase
