Description

[Detailed description of the invention] This invention relates to a solenoid valve device that operates a valve body by energizing a solenoid and energizing it. Regarding the structure of the connecting part for connecting.

Conventionally, a configuration is known in which a recess is formed on one surface of the outer wall of the valve body, and an insulating terminal block is fixed therein to support a terminal fitting for connecting an external conductor (for example, in practice). (See Publication No. 51-28819). In the above configuration, when connecting the external conductor, hold the external conductor and approach the valve body attached to the machine (valve body located in a narrow place or a dangerous place at a high place), and then connect the external conductor for a long time. There was the inconvenience (danger) of having to do connection work on time. Furthermore, when the outer conductor was pulled after the connection work, the connecting fittings were sometimes deformed, making it difficult to repair them. Furthermore, with the above configuration, there is the difficulty of having to form a recess in the outer wall of the valve body in advance when molding the valve body, and on top of that, the manufacturer of the valve body (ironworker) has to control the placement of the electrician's product. There was also a truly unreasonable situation in which the valve body had to be machined with this in mind.

Therefore, the present invention solves the above-mentioned problems, and can relay the power supply from the external conductor to the solenoid, and can easily connect the external conductor to perform the relay. To provide a structure in which a member for connection can be covered without using any other extra member.

The configuration of the present invention is as follows. The present invention includes a solenoid valve body with a solenoid detachably attached to its side, a terminal block, and a support plate protruding from the edge of the terminal block so as to surround one side of the terminal block. The terminal box is formed into a box-like shape with one side open and is itself made of an electrically insulating material. One surface faces the solenoid valve body with a space in between, and the opening of the terminal box is removably fixed even when the opening of the solenoid valve body is covered by the peripheral wall surface of the solenoid valve body, and the terminal box is inside the terminal box. In some cases, a connection terminal to which an external conductor can be connected is attached to one side of the terminal block,
Furthermore, when the connection terminal is electrically conductive and the terminal box is attached to the solenoid valve body, the pin connection body is placed in a position where it can be connected to the pin contact that protrudes from the solenoid toward the terminal box position. Moreover, the pin contact introduction part of the pin connection body is formed so that it can be freely inserted and extracted from two directions: the side facing the solenoid valve main body and the side facing the solenoid perpendicular to the main body, and A wire opening for passing an external conductor is provided near the mounting position of the connection terminal on the stand, and its function is as follows.

The hollow terminal box can be separated from the solenoid valve body. When inserting a conductor through the wire port provided on the terminal block and connecting it to the connection terminal at the bottom of the terminal box, the conductor can be fixed to the terminal by operating from the opening of the terminal box. After the conducting wire is fastened, even if the conducting wire is pulled outward, the pulling force acts in a direction that presses the terminal against the inner wall of the terminal block. When the lower opening of the terminal box is placed over the solenoid valve body, the pin connection body is placed in a predetermined position (a position where it can be connected to a pin contact), and the exposed part of the connection terminal (electrified part) is covered with an electrically insulating material. terminal block and
It is also wrapped in a terminal box consisting of a support plate. Further, as a result, the pin contact introduction portion of the pin connection body can be inserted and extracted from two directions: the side facing the electromagnetic valve body and the side facing the solenoid orthogonal thereto. When attaching or detaching the terminal box to the solenoid valve body, make sure that the solenoid is attached to the solenoid valve body (with the pin contact protruding as shown in Figure 1) and that the terminal box is facing in the Y direction. The solenoid can be attached and detached, and the solenoid can be attached and detached in the X direction even when the terminal box remains attached to the solenoid valve body as shown in FIG.
