When the housing is attached to the equipment case with the standby connector attached, the equipment side terminal is introduced from the attachment surface, so that the equipment side terminal and the wire side terminal held by the standby side connector are mutually connected. The tips are overlapped with each other in an orthogonal posture. Next, the terminals of the device-side terminal and the electric wire-side terminal are bolted through the opening of the housing that is opened by removing the service cover, so that both terminals are electrically connected. Finally, by fitting the movable connector provided at the end of the harness to the standby connector, each electric wire is individually connected to the electric wire terminal, thereby forming a predetermined conductive path.
Since the harness is pulled out from the side surface adjacent to the mounting surface of the housing at right angles, it is possible to save the space on the protruding end side of the housing, that is, the device connector device. As a means for pulling out the harness to the side, the I-shaped terminals having a simple structure are bolted in an orthogonal posture, so that the entire structure such as the standby side connector and the housing can be easily fastened.

The following configuration may also be used.
(1) A removal preventing mechanism is provided for preventing the service cover from being removed before the movable connector is detached from the standby connector.
The service cover cannot be removed before the movable connector is detached from the standby connector. In other words, the service cover can be removed only after the movable connector is detached from the standby connector and the energized state of the conductive path is released.

(2) The movable-side connector and the standby-side connector include a fastening portion in which a bolt that is freely supported only for rotation by a bolt support portion provided in the movable-side connector is provided facing the housing. The service cover is held in a fitted state by being screwed into the bolt hole, and the service cover is covered with the bolt sandwiched between the bolt support portion and the fastening portion in a form in which the bolt is penetrated. The removal preventing mechanism is configured by providing the clamping plate.

When the bolt is loosened and the movable connector is detached from the standby connector together with the bolt, the clamped plate is released from being locked to the bolt, and the service cover can be removed.

(3) The service cover is attached by closing the opening of the housing by screwing, and the movable connector is fitted to the standby connector. As long as it is provided, a cover portion that covers the screwing portion of the service cover is provided, whereby the removal prevention mechanism portion is configured.
When the movable connector is fitted to the standby connector, the cover provided on the movable connector covers the screwing portion of the service cover. When the movable side connector is detached from the standby side connector, the cover part moves and the screwing part is opened, so that the screw can be loosened, that is, the service cover can be removed.

  (4) The structure of the portion where the service cover is mounted by closing the opening is a waterproof structure through packing. Infiltration from the opening is prevented.

  According to the device connector device disclosed in the present specification, it is possible to save space while keeping the structure simple.

Each of the 61 round pin terminals 62 is individually connected to form a predetermined conductive path. At the same time, the short pin mounting portion 102 provided on the fitting surface of the movable connector 80 is fitted with the first connection portion 113 provided on the fitting surface of the standby connector 60, thereby The end and the short pin 101 are connected via the relay terminal 115, the interlock circuit 100 is turned on, and the conductive path is made conductive.

  When removing the connector device from the device case for maintenance or the like, the following procedure is used. First, the movable connector 80 of the terminal of the harness WH is detached from the standby connector 60 attached to the housing 20. Specifically, the movable side connector 80 is gradually detached by loosening the third bolt 92, and after the third bolt 92 is removed from the bolt hole 38, the movable side connector 80 is manually pulled out from the standby side connector 60. Until the movable connector 80 is completely removed from the standby connector 60, the short pin 101 is pulled out from the relay terminal 115 connected to the base end of the relay conductor 110, and the interlock circuit 100 is turned off. Thus, the conduction path is cut off.

  Subsequently, the service cover 50 is removed by loosening the second bolt 53, but the movable side connector 80 is detached from the standby side connector 60 as described above, so that it is supported by the bolt support 90 of the shield shell 87. Since the third bolt 92 that has been moved escapes to the rear of the sandwiched plate 56 provided in the extending portion 52 of the service cover 50, the lock on the service cover 50 is released and the service cover 50 is lifted and removed. Can do. As a result, the opening 40 is opened, and when the fourth bolt 75 is loosened and removed through the opening 40 and the work hole 34, the connection between the end portions of the device-side terminal 10 and the wire-side terminal 61 is released.

  When the casing 20 is pulled to the near side from such a state, the casing 20 is gradually removed while the two device-side terminals 10 gradually come out rearward from the mounting surface 21 of the casing 20. At this time, the interlock connector 105 is pulled out while being fitted to the connector portion 120. However, after the device-side terminal 10 is completely removed, the interlock connector 105 is inserted into the introduction hole 22 of the housing 20 and the interlock connector 105 is inserted. Remove from the connector part 120. Thereby, it becomes possible to remove the housing | casing 20 completely from the case of an apparatus.

Here, before performing the operation of removing the connector device from the case as described above, before the movable side connector 80 is detached from the standby side connector 60 attached to the housing 20, that is, when the conduction path is still in a conduction state. If the service cover 50 is removed first, the conductive path is opened through the opening 40, so that the conductive path may be accidentally touched.
However, in this embodiment, in order to hold the standby side connector 60 and the movable side connector 80 in the fitted state, only the rotation is freely supported by the bolt support portion 90 of the movable side connector 80 (shield shell 87). When the bolt 92 is screwed into the bolt hole 38 of the second fastening portion 37 provided in the housing 20, the third bolt 92 is held and formed on the extended portion 52 of the service cover 50. It has a structure that penetrates the insertion groove 57 of the plate 56. With this structure, the removal prevention mechanism A1 is configured.

  Therefore, even if the second bolt 53 is first loosened and the service cover 50 is lifted, the bottom edge of the insertion groove 57 of the sandwiched plate 56 provided in the service cover 50 is screwed into the third bolt 92. The service cover 50 cannot be removed by being locked to the shaft portion. In other words, the service cover 50 can be removed only after the movable connector 80 is detached from the standby connector 60 and the conductive path is cut off. As a result, the conductive path in the conductive state is prevented from being opened to the outside through the opening 40.

According to this embodiment, the following effects can be obtained.
Since the harness is structured to be pulled out from the side surface adjacent to the mounting surface 21 of the housing 20 on the device case at a right angle, space saving on the protruding end side of the housing 20, that is, the device connector device can be achieved. Can be planned. As a means for pulling out the harness WH to the side, the device-side terminal 10 and the wire-side terminal 61 made of an I-shaped terminal having a simple structure are bolted in an orthogonal posture. The whole structure can be easily fixed.

  Further, as long as the movable connector 80 is held in a fitted state with the standby connector 60, the service cover 50 cannot be removed. In other words, the movable connector 80 is detached from the standby connector 60 and becomes conductive. The service cover 50 can be removed only after the road is blocked. Therefore, it is possible to prevent the conductive path in the conductive state from being opened to the outside through the opening 40.

<Embodiment 2>
Next, a second embodiment will be described with reference to FIGS. In the second embodiment, in order to prevent the service cover 50X from being removed at an incorrect timing, an example in which means different from the first embodiment is taken is illustrated. In the following, differences from the first embodiment will be mainly described, and members and parts having the same functions as those in the first embodiment will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

In the present embodiment, the service cover 50 </ b> X covering the opening 40 formed on the upper surface of the housing 20 has a substantially rectangular cover body 51 that covers the upper surface of the housing 20, and the upper portion of the right edge of the housing 20. And a bent portion 52X bent downward from the right edge of the cover body 51 so as to be applied to the cover body 51.
Similarly to the first embodiment, three positions on the peripheral edge of the cover main body 51, that is, the left front corner corresponding to each mounting seat 43 provided on the upper surface of the housing 20, a position slightly approaching the left end on the back edge, In addition, bolt insertion holes 53 </ b> A through which the second bolts 53 are inserted are formed at three positions that are slightly closer to the front end portion on the right edge. When the service cover 50 </ b> X is attached to the upper surface of the casing 20, the position where each bolt insertion hole 53 </ b> A is disposed becomes the bolt fastening portion 150.

  On the other hand, in the movable connector 80, a cover 152 is formed to project forward from the top of the bolt support 90 provided on the shield shell 87. When the movable connector 80 is normally fitted to the standby connector 60, the cover 152 is set at a position slightly offset from the front end of the right edge of the cover body 51 as shown in FIG. It is possible to advance to a position that can cover the upper portion of the bolt fastening portion 150X. With such a structure, the removal preventing mechanism A2 is configured by the structure.

The operation of the second embodiment is as follows. The housing 20 is attached to the case of the device in the same manner as in the first embodiment, and inside the housing 20, the device-side terminal 10 and the wire-side terminal 61 are fastened and connected by the fourth bolt 75 in an orthogonal posture. The opening 40 is watertightly closed with a service cover 50X.

When the fitting is started, the tip of the third bolt 92 supported by the bolt support portion 90 of the shield shell 87 engages with the bolt hole 38 of the second fastening portion 37 provided in the housing 20, and then Then, the third bolt 92 is screwed into the normal position shown in FIG.

When the regular fitting is performed, a predetermined conductive path is similarly configured, and the interlock circuit 100 is turned on to bring the conductive path into a conductive state.
During this time, after the tip of the cover part 152 protruding forward from the top of the bolt support part 90 passes over the second fastening part 37 of the housing 20, as shown in FIG. It will be in the state which covered the upper part of the bolt fastening part 150X set to the right edge in the cover main body 51 of this.

When the connector device is removed from the case of the device for maintenance or the like, the third bolt 92 is loosened, and then the movable connector 80 is pulled out to be detached from the standby connector 60. Meanwhile, the interlock circuit 100 is turned off and the conduction path is cut off.
Subsequently, the service cover 50X is removed by loosening the second bolt 53. However, as the movable connector 80 is detached from the standby connector 60 as described above, the movable connector 80 (shield shell 87) is removed. The cover portion 152 provided on the right side of the cover main body 51 escapes from the upper side of the bolt fastening portion 150X set on the right edge to the right side, and all the three bolt fastening portions 150 are opened. Therefore, the service cover 50X can be removed while being lifted upward by loosening and removing the second bolts 53 at three locations.

  As a result, the opening 40 is opened, and by loosening and removing the fourth bolt 75, the connection between the end portions of the device-side terminal 10 and the wire-side terminal 61 is released. Thereafter, similarly, the housing 20 is completely removed from the case of the device by pulling the housing 20 to the near side and removing the interlock connector 105 from the connector portion 120.

  On the other hand, even if it is attempted to remove the service cover 50X before the movable side connector 80 is detached from the standby side connector 60, at least one bolt fastening portion 150X is covered with the cover portion 152. Thus, the second bolt 53 arranged on the bolt fastening portion 150X cannot be loosened, that is, the service cover 50X cannot be removed. Therefore, the conductive path in the conductive state is prevented from being opened to the outside through the opening 40.

  According to the second embodiment, as in the first embodiment, the harness WH is drawn from the side surface adjacent to the mounting surface 21 of the housing 20 at a right angle. It is possible to save space on the protruding end side of the apparatus, and as a means for that purpose, the device side terminal 10 and the wire side terminal 61 made of an I-shaped terminal with a simple structure are bolted in an orthogonal posture. Therefore, the entire structure such as the standby connector 60 and the housing 20 can be easily secured.

  In addition, as long as the movable connector 80 is held in the fitted state with the standby connector 60, the cover 152 cannot cover the bolt fastening portion 150X and loosen the second bolt 53, that is, the service cover 50X In other words, the service cover 50X can be removed only after the movable connector 80 is detached from the standby connector 60 and the conductive path is cut off. Therefore, it is possible to prevent the conductive path in the conductive state from being opened to the outside through the opening 40.
