Description

Description: TECHNICAL FIELD The present invention relates to a handle illumination mechanism of a circuit breaker in which a handle block and a main body are separated and the handle specifications are selectable.

[Background Art] In a conventional circuit breaker of this type, a neon lamp for illuminating a handle and a resistor are arranged inside the main body of the breaker, and electric wires are routed inside the main body, so that workability is poor and a contact mechanism is provided. There is a problem that the electric wire and the electric wire are likely to come into contact with each other, and it is necessary to distinguish between the specification with the handle illumination and the specification without the illumination at the stage of manufacturing the parts.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the present invention is to manufacture a lamp block for steering wheel illumination as a separate component so that it can be attached with one touch at the assembly stage. Therefore, it is an object of the present invention to provide a circuit breaker of this kind which can improve the reliability of parts and the workability of assembling and simplify the inventory management.

DISCLOSURE OF THE INVENTION The circuit breaker according to the present invention, however, has a main body having a built-in contact mechanism and protruding external terminals on its lower surface, and a transparent handle attached to the upper portion of the main body so that the transparent handle is swingable. In a circuit breaker composed of a supported handle block, a V groove formed in a vertical portion is bendable so as to have a U-shape as a whole, and two terminal insertion holes are formed in a lower horizontal portion. L-shaped synthetic resin plate, handle lighting lamp mounted on the outer surface of the upper end bent portion of the synthetic resin plate, conductor spring and lamp provided along the inner side surface of the synthetic resin plate and mounted in the terminal insertion hole A lamp block made up of a connecting conductor for connecting and is provided, an external terminal is fitted and inserted in the terminal insertion hole, and the upper end bent portion is sandwiched between the handle block and the main body. Direct lamp power In particular, it is characterized in that the lamp block arranged along the outer surface of the main body portion is clamped and fixed between the main body portion and the handle block.

[Embodiment] FIG. 1 shows an embodiment of a circuit breaker according to the present invention. A main body 1 having a rectangular parallelepiped shape has a built-in contact mechanism for detecting an overcurrent and breaking the circuit. The external terminal 2 projects from the lower surface of the portion 1. Further, a handle block 4 in which a translucent handle 3 is pivotably supported is attached to an upper portion of the main body 1.

The lamp block A, which is an essential part of the present invention, is composed of an L-shaped synthetic resin plate 5 which has a V-shaped groove 6 acting as a hinge in the vertical portion 5a and which is bendable so that the whole is U-shaped. A conductor spring 8 is mounted in the two terminal insertion holes 7 formed in the lower end horizontal portion 5b of the synthetic resin plate 5, and a handle illumination lamp 9 and a lamp 9 are provided on the outer surface of the upper end bent portion 5c of the synthetic resin plate 5. A resistor 10 connected in series to the lamp 9 is mounted, and a connecting conductor 12 for connecting the conductor spring 8 and the lamp 9 is further inserted into a concave groove 11 provided along the inner surface of the synthetic resin plate 5. Has been done. In addition, 13 is an engaging projection provided on the side surface of the main body 1, 14
Is an engaging hole provided at the lower edge of the handle block 4, and 15 is a handle shaft.

At the time of assembly, first, the external terminal 2 is inserted into the terminal insertion hole 7, the lower end horizontal portion 5b and the vertical portion 5a of the synthetic resin plate 5 are brought into close contact with the lower surface and the side end surface of the main body portion 1, respectively, and the handle block The upper end bent portion 5c is bent at a right angle to be sandwiched between the handle block 4 and the upper surface of the main body 1 when the lamp 4 is attached, and the power source of the lamp 9 is the input side or the output side. From the external terminal 2 of the book to the connecting conductor 12 and the resistor
Supplied through 10. Although an electric wire is used as the connection conductor 12 in this embodiment, the connection conductor 12 can be formed by printed wiring by providing the V groove 6 on the outer surface.

[Effects of the Invention] As described above, according to the present invention, the power source of the handle illumination lamp 9 can be directly taken from the external terminal, and the main body 1
Since it is not necessary to connect the electric wire inside the lamp, the work of connecting the lamp 9 is facilitated, and there is no risk of the electric wire coming into contact with the contact mechanism in the main body 1, so that the reliability is improved. In addition, since it is not necessary to manufacture two types of main body 1 by distinguishing between the specification with handle illumination and the specification without illumination, there is an advantage that inventory management can be simplified.
