  In the cable connector 10 in which the receptacle 20 and the plug 30 are connected in this way, when the plug 30 is pulled out of the receptacle 20 using the cable connector pulling tool 100, first the cable connector 10 is pulled into the cable connector pulling tool 100. Set.

FIG. 10 is a view for explaining the operation of the cable connector pulling tool. Specifically, FIG. 10 is a diagram showing a state in which the cable connector pulling tool is set in the cable connector.
FIG. 11 is a diagram for explaining the operation of the cable connector extraction tool. Specifically, FIG. 11 shows a cable connector 10 of FIG. 10 in which a plug is pulled out of the receptacle by the cable connector extraction tool. It is a figure which shows the state extracted.

  As shown in FIGS. 7 and 10, in the cable connector 10 being connected, the axis line (the line along the connecting direction of the plug 30 and the receptacle 20) in the direction in which the receptacle 20 and the plug 30 are fitted and connected to each other by insertion. That is, it is arranged along the connection axis that is the axis between the cables 2 and 3. That is, the receptacle 20 and the plug 30 are firmly connected in a straight line.

  In such a cable connector 10, the connection portion 15 between the receptacle 20 and the plug 30 is sandwiched, and the first engagement portion 110 and the second engagement portion 140 are engaged with the receptacle-side recess 27 and the plug-side recess 37. .

  Specifically, the cable connector extraction tool 100 is disposed on the side of the connection portion 15, and the first engagement portion 110 is externally fitted to the plug-side recess 37 from the side of the plug-side recess 37. In addition, the second engagement portion 140 is externally fitted to the receptacle-side recess 27 from the side of the receptacle-side recess 27.

  At this time, the grip portion 120 of the cable connector pull-out tool 100 is disposed along the axis C, which is the connection axis in the connection direction of the cable connector 10, and forms a 45 degree angle with respect to the axis C. Placed in. In other words, the grip portion 120 is formed on a surface that forms an angle of less than 45 degrees with respect to the axis C when the first engagement portion 110 and the second engagement portion 140 are externally fitted in the recesses 27 and 37. Be placed. In addition, as long as the arrangement | positioning position of the holding part 120 is arrange | positioned in the position which forms an angle of less than 45 degree | times with respect to the axis C, you may be comprised so that it may arrange | position in any position.

  Then, as shown in FIG. 10, the cable connector 10 and the cable connector extraction tool 100 set on the cable connector 10 are gripped so as to be wrapped. At this time, since the grip portion 120 is disposed at a position that forms an angle of 45 degrees with respect to the axis C in the connection direction of the cable connector 10, the operator easily grips the cable connector pull-out tool 100. In addition, it is easy to put a fingertip on the outer periphery of the cable connector 10. Note that the operator may hold the cable connection portion 100 so that the fingertip is hung on the uneven portion of the gripping portion, and the vicinity of the thumb ball is applied to the connection portion of the cable connector 10 and wrapped.

  Then, a load A is applied to the grip portion 120 so that the grip portion 120 approaches the axis C (see FIG. 1) of the cable connector 10.

  Then, with the movement of the grip portion 120, the shaft attachment portion 160 serves as a fulcrum, and the base member 130 and the rotating arm member 150 move in a direction in which they are relatively separated from each other. In other words, the first engagement portion 110 of the distal end portion 131 of the base member 130 and the second engagement portion 140 of the distal end portion 152 of the rotating arm member 150 move in a relatively separated direction.

  At this time, the first engaging portion 110 abuts one side wall of the plug-side recess 37 of the plug 30 at the end portion 112, that is, the front end surface of the plug main body 32, and pulls the plug main body 32 from the receptacle 20 along the axis C. Press in the direction.

  On the other hand, the second engaging portion 140 abuts one side wall of the receptacle-side recess 27 of the receptacle 20 at the end 142, that is, the front end surface of the receptacle body 22, and pulls the receptacle body 22 from the plug 30 along the axis C. Press in the direction.

  As a result, forces in the direction B away from each other act on the cable connector 10 along the axis C.

  As a result, the receptacle 20 and the plug 30 move in the direction B away from each other, and as shown in FIG. 11, the receptacle 20 and the plug 30 are released from the fitted state. That is, in the cable connector 10, the other is pulled out from one of the receptacle 20 and the plug 30.

  As described above, in the cable connector pulling tool 100, the first engagement portion 110 and the second engagement portion 140 are separated from each other by moving the grip portion 120 so as to approach the axis C of the cable connector 10. Move in direction B. As a result, the receptacle 20 and the plug 30 are moved in the direction B away from each other along the axis along the connection direction, and the mutual connection state is released.

  Thus, according to the cable connector pulling tool 100, the cable connection in which the recesses 27 and 37 are formed along the circumferential direction on the outer peripheral surfaces of the receptacle body (receptacle outer package) 22 and the plug body (plug outer package) 32, respectively. The receptacle 20 and the plug 30 of the container 10 can be easily pulled out.

  That is, the cable connector extraction tool 100 has an angle formed by the axis C of the cables 2 and 3 and the grip portion 120 of less than 45 degrees. Therefore, the cable 2 and 3 and the cable connector pulling tool 100 are grasped with one hand, and the plug 20 can be easily plugged from the receptacle 20 simply by bringing the axis C of the cable connector 10, that is, the axis of the cables 2 and 3, close to the grip 120. 30 can be pulled out.

  For this reason, it is not necessary to pull out the plug 30 and the receptacle 20 that are the cable connector 10 while twisting or bending, and the cable connector 10 is not deformed or damaged.

  Further, the cable connector 10 is used by being installed at a position that forms 90 degrees with respect to the axis C of the cable connector 10 (corresponding to the connection direction of the plug 30 and the receptacle 20, that is, the axis of the cables 2 and 3). With this tool, when the cable connector is installed in a very narrow place, it is difficult to pull out the plug and the receptacle because the work is performed with both hands. In particular, when the cable connector is installed when there is no space for the length of the tool, the plug and receptacle cannot be pulled out.

  On the other hand, according to the pulling tool 100 for the cable connector, even when the cable connector 10 is very narrow, the receptacle in the cable connector 10 can be easily set by extending and holding one hand. The plug 30 can be pulled out from 20. That is, even when the cable connector 10 is housed in a hand hole beside the runway as an aerial lighting wiring, as a guide light wiring disposed beside the runway, Can be easily pulled out.

  In addition, when the angle formed by the grip part 120 and the axis C exceeds 45 degrees, it becomes difficult for an operator to grip the grip part 120, and it becomes difficult to use.
