Description

[Detailed description of the invention] This invention relates to a relay with a terminal block cover, and its main purpose is to protect the terminals of the terminal block to which the relay is attached to prevent short circuits and electric shocks. .

Conventionally, in plug-in type relays, that is, the relays are installed by inserting the terminal pins 2 protruding from the base into the sockets 6 of the terminal block 5, the terminals 7 of the terminal block 5 are exposed as shown in Fig. 1, so the live parts are exposed. There was a risk of electric shock or short circuit if the product was exposed and touched.

The present invention has been devised in view of the above points, and will be described in detail below based on the embodiments shown in the figures. The relay A is constructed by housing electronic components such as a relay coil and contacts in a case consisting of a base 1 and a cover 3, and a plurality of terminal pins 2 protrude from the bottom surface of the base 1 to communicate with the relay coils and contacts, respectively. The cover 3 is attached by fitting the base 1 into the lower end opening, and a skirt 4 that is elastically deformable extends obliquely outward from the lower end edge of the cover 3 integrally with the cover 3.
This skirt 4 is connected to the terminal pin 2 as shown in FIG.
When inserting the terminal into the socket 6 of the terminal block 5, the lower end may run along the outer periphery of the top surface of the terminal block 5 and cover the terminal 7 exposed on the top surface of the terminal block 5, causing an electric shock if the terminal 7 is touched with the hand. This prevents other foreign objects from coming into contact with it and causing a short circuit. Although it is desirable that the skirt 4 extends from the entire circumference of the lower end of the cover 3, it is not necessarily limited to this.
It may extend beyond the necessary portion.

As mentioned above, the present invention extends an elastically deformable skirt from the lower edge of the cover to the outside of the base and downward.
Since the top surface of the terminal block is covered with the skirt, the skirt can electrically insulate the top surface of the terminal block, preventing electric shocks caused by touching the terminals exposed on the top surface of the terminal block, or by other foreign objects coming into contact with the terminals. In addition to preventing short circuits, when connecting or disconnecting lead wires from terminals, the skirt can be flipped up with the cover still attached, making it easy to connect the relay to the relay. The lead wires can be easily attached and detached.

[Brief explanation of the drawing]

FIG. 1 is a front view showing a conventional example, FIG. 2 is a perspective view showing an embodiment of the present invention, and FIG. 3 is a front view of the same, in which 1 is a base, 2 is a terminal pin, 3 is a cover, 4 is a skirt, and 5 is a terminal block.

Claims (1)

[Scope of utility model registration request] In a configuration in which a terminal pin protruding from the lower surface of the base of the relay body is inserted into the upper surface of the center part of the terminal block, the terminal pin is made of an elastic material such as rubber and extends diagonally downward from the lower edges of both sides of the relay cover attached to the base. A relay with a terminal block cover, in which the skirt extends and elastically contacts the upper surface of the terminal connection part at both ends of the terminal block, thereby insulating the terminal connection part.
