If it does in this way, the top plate part 11 of the cover 10 will be pressed against the suction cup part 84 of the adsorption | suction member 80 of the cover holding tool 71, and the air in the suction cup part 84 will be extruded. As a result, the top plate portion 11 of the cover 10 is attracted to the suction cup portion 84, and the cover 10 is held by the cover gripper 71.

  In order to attach the cover 10 held by the cover gripper 71 to the connector 20, the side plate 73 of the cover gripper 71 is pinched and gripped and supported by the connector support base 51 as shown in FIGS. 22 and 23. The connector 20 is brought close to the connector 20 from above. At this time, the positioning portions 72 a and 73 a of the cover gripper 71 are brought into contact with the positioning surface 53 a of the connector support base 51 and the cover 10 held by the cover gripper 71 with respect to the connector 20 supported by the connector support base 51. To position.

  In this state, the cover gripper 71 is pushed into the connector 20 side. Then, the locking projections 28 of the housing 21 of the connector 20 are fitted into the locking holes 13 of the cover 10 held by the cover gripping tool 71, and the locking force between the locking projections 28 and the locking holes 13 is engaged. Thus, the cover 10 is attached to the housing 21 of the connector 20. At this time, since the operator's finger is caught by the anti-slip portion 78 formed on the side plate 73 of the cover gripper 71, the operator can stably grip the cover gripper 71.

  When the cover 10 is attached to the connector 20, the cover gripping tool 71 is lifted and removed from the cover 10. Here, the suction force of the suction cup portion 84 to the top plate portion 11 is made weaker than the locking force between the locking projection 28 and the locking hole 13. Thereby, the cover gripper 71 is pulled away from the cover 10 by pulling up. Thereafter, the connector 20 to which the cover 10 is attached is removed from the connector support base 51.

  Thus, according to the cover gripping tool 71 according to this modification, the cover 10 can be easily held by the cover gripping tool 71 by sucking the top plate part 11 of the cover 10 to the suction cup part 84 of the suction member 80. Thus, the workability of attaching the cover 10 to the connector 20 can be further enhanced.

  Next, an engagement release jig used when the connector 20 coupled to the device-side connector 40 is removed from the device-side connector 40 will be described.

  FIG. 24 is a perspective view of a solenoid including a device-side connector to which a connector is connected. FIG. 25 is a cross-sectional view of the connector connected to the device-side connector. FIG. 26 is a perspective view of an engagement releasing jig used when removing the connector from the device-side connector. FIG. 27 is a perspective view of the disengagement jig for explaining the work of removing the connector from the device-side connector using the disengagement jig. FIG. 28 is a diagram for explaining a connector removal operation from the device-side connector using the engagement release jig, and FIGS. 28A to 28C are respectively connected to the device-side connector. It is sectional drawing of a connector. FIG. 29 is a cross-sectional view of the connector connected to the device-side connector for explaining the connector removing operation from the device-side connector using a bar-shaped tool.

  As shown in FIGS. 24 and 25, the connector 20 to which the cover 10 is mounted by the cover mounting jig 50 according to the above embodiment is connected to a device-side connector 40 provided on the solenoid 44, for example. When the connector 20 is connected to the device-side connector 40, the upper surface protrusion 27 provided on the housing 21 of the connector 20 passes through the passage 46 formed on the housing 45 of the device-side connector 40, and has a claw shape provided on the housing 45. Are engaged by engaging with the locking portion 41.

  As shown in FIG. 26, the disengagement jig 90 has a handle portion 91 and a metal fitting portion 92. The handle portion 91 is formed in a round bar shape that is easy for an operator to hold, and a metal fitting portion 92 is disposed at the tip of the handle portion 91. The metal fitting portion 92 is formed of a metal plate, and includes a fixing portion 93 extending in a bar shape, a contact plate portion 94 divided into two portions, and a lock provided between the contact plate portions 94. And a release protrusion 95. The fixed portion 93 extends into the handle portion 91 and is integrated with the handle portion 91. The unlocking protrusion 95 is bent about 90 ° to one side.

  In order to remove the connector 20 from the device-side connector 40, first, the handle portion 91 of the disengagement jig 90 is gripped, and the contact plate portion 94 is moved between the device-side connector 40 and the cover 10 as shown in FIG. The lock release protrusions 95 are inserted into the passages 46 of the housing 45 by being arranged on both sides of the connector 20 exposed between them.

  Next, as shown in FIG. 28A, the handle 91 is tilted in the direction opposite to the direction in which the unlocking protrusion 95 protrudes (the direction of arrow A in FIG. 28A). In this way, as shown in FIG. 28 (b), the contact plate portion 94 comes into contact with the cover 10 and the housing 45, and these contact portions become the fulcrums S1 and S2, and the tip of the unlocking projection 95 is It is displaced in a direction away from the connector 20.

  Then, as shown in FIG. 28 (c), the locking portion 41 is lifted by the lock release protrusion 95, and the engagement between the locking portion 41 and the upper surface protrusion 27 is released. At this time, the cover 10 is pressed and displaced in the direction away from the housing 45 (the direction of arrow B in FIG. 28C) by the contact plate portion 94 that is in contact with the cover 10. As a result, the connector 20 is detached from the housing 45.

  Here, in order to remove the connector 20 from the housing 45 of the device-side connector 40 without using the disengagement jig 90, as shown in FIG. 29, after the rod-shaped tool K inserted into the passage 46 of the housing 45. The locking portion 41 is lifted by pulling the end side away from the connector 20 (in the direction of arrow C in FIG. 29). Then, while maintaining this state, the connector 20 is pulled away from the housing 45 (in the direction of arrow D in FIG. 29) to be detached from the housing 45.

  As described above, in the case of a simple bar-shaped tool K, the lifting operation of the locking portion 41 by the tool K and the pulling-out operation of the connector 20 during the lifting work must be performed. For this reason, the workability of the work of removing the connector 20 is poor, and it may be difficult to remove the connector 20 particularly in a narrow work space.

  On the other hand, if the engagement releasing jig 90 is used, the lock release protrusion 95 is inserted into the passage 46 of the housing 45 and the handle portion 91 is tilted in a predetermined direction, whereby the front and back covers 10 of the abutting plate portion 94 are disposed. In addition, the lever principle that uses the contact points with the housing 45 as the fulcrums S1 and S2 makes it easy to release the engagement between the locking portion 41 and the upper surface protrusion 27 and to detach the connector 20 from the housing 45 simultaneously with a light force. Can be done. Therefore, the connector 20 can be easily detached from the device-side connector 40 of the solenoid 44 even in a narrow work space.

  In the above example, the contact portion of the contact plate portion 94 with the cover 10 is defined as the fulcrum S1. However, a portion where the contact plate portion 94 contacts the connector 20 and becomes the fulcrum S1 is formed in advance. Thus, the connector 20 can be easily detached from the housing 45 of the device-side connector 40 using the disengagement jig 90 even without the cover 10.
