Description

  The present invention relates to a control device capable of detaching a base and a main body.

  For example, a control device such as a temperature controller is used as a control unit in which an optimum control device is selected according to the type and function of input / output according to the application, and a plurality of control devices are arranged adjacent to each other. In order to cope with the optimal control unit arbitrarily and to allow only the control device to be replaced in the event of a failure, in recent years, only the main body can be removed while the base of the control device is attached to the DIN rail. The number of control devices is increasing.

For example, Patent Document 1 discloses a control device in which a main body and a base can be attached and detached while the base is attached to a DIN rail, and a locking claw is formed on the upper surface of the base and elastically deformed on the upper surface of the main body. The base and the main body can be attached and detached easily by having a spring part and a button for engaging one end of the spring part with the locking claw and operating the engagement with the locking claw at the other end. A device unit attaching / detaching mechanism and a control device that can be performed in the same manner are disclosed.
Here, when wiring work is performed on a control unit in which a plurality of control devices that can be attached and detached from the main body and the base are arranged adjacent to each other, a force is generated in a direction in which the control devices repel each other from stress due to the wired cables, There may be a gap between the main bodies of the control device, and the control device may not be installed as designed. In this way, there is a gap between the control devices, and if the control device is not properly installed, the connection between the base and the main body may be hindered, and there may be a problem in the malfunction or safety or durability of the control device. In addition, since the control device cannot be installed as designed, the external dimensions after connection become large and it cannot be installed on the panel as planned. It becomes a problem in appearance.

  In a control unit in which a plurality of control devices are arranged adjacent to each other, for example, Patent Document 2 includes a slide lock member on the upper surface and the lower surface of the control device. A connection structure is disclosed in which members are locked between adjacent control devices by locking hook-shaped connecting pieces of adjacent control devices.
