Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a terminal unit of a remote control wiring device used for remote control of lighting, multi-point operation and the like.

(Prior Art) Conventionally, remote lighting of offices, hospitals, department stores, etc.
The remote control circuit illustrated in FIG. 3 is adopted,
The terminal unit T / U is built in the relay control panel B. In the figure, S1 to S5 are arranged in each room or remote control switch, S6 is a central control switch installed in the central control room, U1 is a remote control relay control carinal unit, U2 is a transmission unit, Ry1 to Ry12 are A relay, L is a load, that is, a fluorescent lamp, T is a remote control transformer, and M is an amplifier.

The terminal unit T / U is composed of a unit body in which a recess is formed between the control signal side and the load side terminal, and a cover that covers the recess and the load side terminal, and an operation window for a channel setting switch is formed in the recess. ing. The cover is attached to the unit body with screws.

(Problems to be solved by the invention) By the way, in the above-mentioned terminal unit of the related art, since the cover is attached by screws, screw parts are indispensable, the number of parts increases, and screw tightening work is required, resulting in poor workability and cost. There was a problem such as getting expensive.

This invention was devised by paying attention to the above-mentioned circumstances, and the purpose thereof is to enable one-touch fitting without the need for screw parts for cover attachment, and to improve workability and design. It is to provide a terminal unit capable of reducing the cost.

(Means for Solving the Problems) In order to achieve the above object, the present invention has taken the following technical means.

That is, according to the invention, a unit main body in which a recess is formed between the control signal side and the load side terminal, and an operation window for a channel setting switch is formed in the recess, and a cover for covering the recess and at least the load side terminal. In the terminal unit, the cover is provided with a locking hook on the back side, and the recess of the main body is provided with a hook engaging hole corresponding to the locking hook. There is a point.

(Operation) According to this invention, the cover is aligned with the unit body,
By simply pressing the cover, the locking hook of the cover is fitted into the hook engaging hole of the unit body and locked. Further, when the cover is removed, it may be separated from the unit body while the locking hook is pushed inward.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, the terminal unit 1 comprises a unit body 2 made of synthetic resin and a cover 3, and the unit body 2
Although it is a substantially rectangular box shape, it is composed of a body and a body cover (not shown), and a concave portion 4 having an opening in the width direction and the upper portion is formed in the central portion of the upper surface. The unit body 2 is provided with terminal mounting portions 5 and 6 at both ends in the longitudinal direction adjacent to the recess wall 4A, and one terminal mounting portion 5 is provided with the control signal side terminal 7.
Load-side terminals 8 are mounted on the other terminal mounting portions 6, respectively. Further, in the upper surface 4B of the concave portion 4 of the unit main body 2,
Operation window for built-in channel setting switches 9 and 10 1
1, 12 are formed, and rectangular hook engagement holes 13 elongated in the longitudinal direction of the unit body 2 are provided at both ends in the width direction. Reference numeral 14 is a mounting hole for a control panel or the like.

The cover 3 has a substantially rectangular box shape and has side walls 3A and 3B having the same height as the height of the recessed wall 4A of the unit body 2. One side end of the longitudinal direction is cut away from the side wall of the terminal mounting portion 6 side. Therefore, only the top plate 3C that covers the load side terminal mounting portion 6 is provided. And
The side wall 3B in the width direction is slightly recessed inward in the width direction at a portion corresponding to the hook engaging hole 13 of the unit main body 2, and the side wall lower end of the side wall recessed portion 3D, that is, the back side of the cover 3 is engaged with the outer side. Locking hooks 15 from which the stoppers 15A are projected are provided in a protruding manner. The locking hook 15 is provided with a slight spring property so as to be deformed and displaced when pressed inward from both sides in the width direction, and in the fitting engagement state with the hook engagement hole 13, Although it does not disengage at all, the engaging hook 15 and the engaging hole 13 can be engaged with each other by an artificial external force. The springiness of the locking hook 15 also contributes to the fact that the end side wall on the terminal mounting portion 6 side is not provided and the end of the width direction side wall 3B is opened.

According to the above embodiment of the present invention, the engaging hook 15 is easily fitted and locked in the hook engaging hole 13 of the unit body 2 by aligning and pushing the cover 3 into the recess 4 of the unit body 2, The cover 3 is securely fitted to the unit body 2, and the two are not naturally separated from each other. Therefore, no screws or the like are required to attach the cover 3 to the unit body 2, and when removing the cover 3 from the unit body 2, by pushing the lower portion of the side wall recessed portion 3D of the cover 3 inwardly, The locking hook 15 can be separated and removed from the hook engagement hole 13 very easily.

(Effects of the Invention) A terminal unit according to the present invention has a hook engaging hole formed in a recess formed in the unit body, and a cover provided with a locking hook to be fitted into the hook engaging hole on the back surface thereof. Therefore, it is possible to attach the cover to the unit body with a simple operation that aligns the cover with the unit body and pushes it in, that is, with one touch. The two can be separated very easily by pushing in one direction. Therefore, screws for attaching the cover to the unit body are not required, reducing the number of parts and screw tightening work, which not only improves workability and workability, but also enables cost reduction and facilitates parts management. It is possible to obtain a terminal unit with a good design that has a neat appearance without screws as well as tightening.
