- a receptacle shell 71 is provided at the peripheral edge of the opening 61a, and the connector main body 15 is surrounded by the receptacle shell 71. Further, a metal cover member 16 is interposed between the connector main body 15 and the receptacle shell 71.
- the heat generated in the connector main body 15 can be dispersed in the housing 60 and the temperature rise of the connector main body 15 can be suppressed. If the receptacle shell 71 is also made of metal, the heat generated in the connector body 15 can be more efficiently distributed to the housing 60. In this way, suppressing the temperature rise of the connector main body 15 greatly contributes to the realization of a configuration in which the plug 80 is directly connected to the connector main body 15.
- the connector body 15 has a plurality of power terminals Tp and a plurality of signal terminals Ts, and the plurality of power terminals Tp are arranged on the outer peripheral side of the connector body 15.
- the power terminal Tp tends to generate heat more easily than the signal terminal Ts. For this reason, by arranging the power terminal Tp on the outer peripheral side of the connector main body 15 and bringing it close to the cover member 16 and the receptacle shell 71, the heat generated in the connector main body 15 can be more efficiently dispersed in the housing 60. Therefore, the temperature rise of the connector main body 15 can be suppressed more reliably.

Due to the shielding effect of the partition wall 18, noise propagation from the power terminal Tp to the signal terminal Ts is suppressed, so that it is easy to collect many terminals in the connector body 15.
- the edge 16d on the rear side (opening 61a side) of the cover member 16 protrudes from the rear end surface (end surface on the opening 61a side) 15a of the connector body 15.
- the connector body 15 is inserted from the inside of the housing 60 toward the shell body 71B of the receptacle shell 71, that is, from the front to the back.
- the edge 16d protrudes from the end surface 15a, the rear end portion of the connector body 15 can be protected when the connector body 15 is inserted into the receptacle shell 71.
- a guide surface 71e is formed on the front portion (portion on the substrate 11A side) of the inner peripheral surface of the shell body 71B. For this reason, the connector main body 15 can be smoothly inserted into the shell main body 71B.
- a guide surface 16e may be formed on the rear portion (portion on the opening 61a side) of the outer peripheral surface of the cover member 16 so as to shrink toward the rear side (inward). (See FIG. 8). Also in this case, the connector main body 15 can be smoothly inserted into the shell main body 71B. Both the guide surface 71e and the guide surface 16e may be formed.
- the receptacle shell 71 is attached to the housing 60 with a backlash along the back surface of the housing 60 with respect to the opening 61a. For this reason, the position of the receptacle shell 71 can be adapted to variations in the position of the connector body 15. Thereby, the connector main body 15 can be more smoothly inserted into the receptacle shell 71.
- the mounting hole 71d has a vertically long elliptical shape, so that the vertical rattling width is larger than the lateral rattling width. For this reason, it is easy to adapt the position of the receptacle shell 71 to variations in the position of the connector body 15 in the thickness direction of the board 11A.
- the plug cover 83 is attached to the plug shell 81 with a backlash. For this reason, even if the convex part 83b is fitted in the concave part 71a, the connector main body 82 is held with a backlash relative to the opening 83a. Thereby, the position of the connector main body 82 can be adapted to the variation in the position of the connector main body 15. Therefore, the cylindrical portion 84 can be inserted into the cell 17 more smoothly.
- the receptacle shell 71 has a holding portion 71A for holding the plug 80.
- the connector main body 15 is used as a connector for connecting the plug 80
- the driver 10 is pulled out in the front direction and taken out from the housing 60 for replacement, there is no connection destination of the plug 80. For this reason, it is necessary to remove the plug 80 from the robot controller 1 in order to replace the driver 10, and the replacement work of the driver 10 becomes complicated.
- the receptacle shell 71 with the holding portion 71A for holding the plug 80, the driver 10 can be replaced while the plug 80 is attached to the robot controller 1 (see FIG. 9). That is, it is possible to achieve both reduction of the cable inside the housing 60 and simplification of the replacement work of the driver 10.
- connection portion of the external cable 5 in the robot controller 1 is arranged in the fence 6, the effectiveness of being able to replace the driver 10 without removing the plug 80 from the robot controller 1 becomes remarkable.
- a lock mechanism for fixing the plug 80 to the holding portion 71A with a screw or the like may be further provided in order to more reliably prevent the plug 80 from falling off when the driver 10 is replaced.
- the cover member 16 is fixed to the heat sink 13. Thereby, the temperature rise of the connector main body 15 can be suppressed more reliably.
- the cover member 16 may cover the entire circumference of the connector body 15 or may partially cover only one surface of the connector body 15.
- the receptacle shell 71 may surround the entire circumference of the connector body 15.
- the multi-axis receptacle CN1 for the actuator of the articulated robot 2 and the single-axis receptacle CN2 for the external axis actuator need not necessarily be separated.
- a terminal for an external shaft actuator may be included in the receptacle CN1.
- the number of actuators controlled by the driver 10 is not limited to nine axes, and may be a single axis.
- the control target may be anything as long as it is electrically controlled, and is not limited to the articulated robot 2.
- Examples of the control target include a machine tool and a transport device.
- the present invention can be used for a control device attached to an electrically controlled device.
