Reference numeral 18 denotes boots. All of these perform almost the same functions as those shown in FIGS.
[0019]
In FIG. 1, reference numeral 20 denotes a connector plug removal engaging portion which is one of the features of the present invention. The connector plug removal engagement portion 20 has a length in which the slider 8 relatively retreats against the insertion direction of the connector plug and the bias when the latch 13 is disposed in the adapter engagement portion 12. The above play gap (space) 20 'is provided. Therefore, as described below, when the connector plug 5 is inserted into the adapter 1, the removal hook 32 does not prevent the slider 8 from retreating.
[0020]
In FIG. 1, reference numeral 30 denotes a connector attaching / detaching tool, which is formed by a handle portion 31, a removal hook 32 disposed at a tip of the handle portion 31, and an insertion pressure-response piece 33 disposed inside the handle portion 31. ing.
[0021]
As shown in FIG. 3 and the like, the connector attachment / detachment tool 30 is generally formed by connecting a pair of handle portions 31 to each other at an end on the side where the removal hook 32 is not formed in a U-shape. You. The mutually connected handles 31 are usually manufactured by bending a steel plate for a leaf spring into a U-shape by bending or the like.
[0022]
For this reason, the handle portions 31 formed in a U-shape are formed by removing the hooks 32, 32 by elastically deforming the material by pressing the outside of the handle portions 31, 31 by hand and applying a gripping force. The distance between them is reduced, and the original distance can be returned again by releasing the gripping force. In addition, the handle portion 31 needs to be made of steel enough not to bend when the connector plug 5 described later is pushed into the adapter 1.
[0023]
The handle portion 31 can be made of any material as long as it can change the distance between the removal hooks 32 when handled by hand as described above and does not bend when the connector plug is inserted. it can.
