識して行わなくてはならず不便であつた。``Prior art'' This type of conventional plug is, for example,
As shown in Japanese Patent No. 110489, when a plug and a socket are connected, a locking mechanism automatically operates to lock the connected state. Therefore, even if the cord connected to the plug or socket is caught on a hand or foot, there is no risk of the plug and socket coming off. To release the coupling state, the coupling cylinder provided on the outer periphery of the plug is pulled rearward against its biasing force to release the lock. However, in conventional plugs with a locking mechanism of this type, it has not been possible to connect the plugs by holding the connecting cylindrical portion of the plug. Moreover, the coupling cylinder generally occupies a relatively large area on the outer periphery of the plug, and the person using this plug must hold something other than the coupling cylinder, for example, the cap part, when connecting the plugs. This was inconvenient as I had to be aware of this.

なつてプラグはソケツトから抜けない。 To combine such a plug and socket,
The insertion portion 12 of the plug may be inserted into the fitting groove 35 of the socket. In this case, when inserting the insertion portion 12 into the fitting groove 35, the end of the pawl 18 of the locking spring piece 17 is inserted into the fitting groove 35 as shown in FIG. 7A.
However, since the thickness d 1 of the claw 18 and the holding plate 21 and the groove width d 2 are selected as described above, the holding plate 21 is inserted into the holding plate 5 as shown in FIG. 7B. Hooked on the front surface of the socket body 34, the presser plate 21 moves relatively rearward against the biasing force of the coil spring 22. While the locking spring piece 17 is elastically bent inward, the claw 18 and the insertion portion 12 fit into the fitting groove 35.
When the claw 18 enters the engagement recess 38 and faces the engagement recess 38, the elastic force of the locking spring piece 17 causes the claw 18 to enter the engagement recess 38 and engage with it in the axial direction. When the locking spring piece 17 is elastically bent, the presser plate 21 is also elastically bent as shown in FIG. 7B, but when the claw 18 enters the engagement recess 38, the presser plate 21 is elastically deformed. is restored, and the holding plate 21 is inserted into the fitting groove 35 by the action of the coil spring 22. It is preferable to have a corner at the tip of the presser plate 21 so that this insertion can be easily started. In this state, even if the plug is simply pulled against the socket, since the locking spring piece 17, the thickness of the holding plate 21, and the groove width d2 have been selected as described above, the claw 18 will not fit into the engaging recess 38. The plug cannot be displaced enough to be pulled out of the socket, and the plug becomes locked and cannot be removed from the socket.

から抜くことができる。 In this locked state, in order to remove the plug from the socket, the coupling cylinder 23 can be pulled rearward against the biasing force of the coil spring 22. When this is done, the presser plate 21 is pulled rearward via the engagement piece 25 and comes out of the fitting groove 35 as shown in FIG. 7D. Therefore, the end of the locking spring piece 17 can move in the direction in which the pawl 18 protrudes, and by pulling it in the axial direction, the pawl 18 is disengaged from the engagement recess 38, that is, the lock is released and the plug is released. It can be pulled out from the socket.
