Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a terminal device used, for example, in a circuit breaker, and more particularly to a terminal device with improved shielding plates between the terminals.

FIG. 1 is a side sectional view showing a conventional terminal device.

2 is a perspective view showing a shielding plate used in the terminal device shown in FIG. 1. FIG.

Corresponding parts in the figure are designated by corresponding reference numerals.

The same applies to the following drawings.

In Figures 1 and 2, a plurality of terminals 2 are attached to a substrate 1, which is the end of the outer frame that houses the circuit breaker, and the terminals 2 have screws for connecting external conductors (not shown). 3
are screwed together.

The portion 4a of the T-shaped insulating shielding plate 4 as shown in FIG. It is fixed to the substrate 1 by screws 5 inserted into the holes 4b.

In this conventional terminal device, the shield plate needs to be shaped like a T-shaped plate in order to be fixed to the board 1, and screws 5 are required, which has disadvantages in terms of structure and installation.

This idea was made in view of the conventional drawbacks.

This invention will be explained below with reference to the drawings.

FIG. 3 is a developed plan view showing one embodiment of the terminal device according to this invention.

FIG. 4 is a perspective view showing an embodiment of the shielding plate used in the terminal device shown in FIG. 3.

FIGS. 5 and 6 are explanatory diagrams of this invention.

3 and 4, a plurality of terminals 2 are attached to a substrate 1, and screws 3 for connecting external conductive wires (not shown) are screwed to the terminals 2.

A shielding plate 4 having a thin tip portion 4C having a convex portion 4d as shown in FIG. 4 is inserted into a groove 1a having a concave portion 1d at the end portion as shown by the arrow in FIG.

That is, when the shielding plate 4 is inserted into the groove 1a, the tip end 4C of the shielding plate 4 is elastically deformed to fit into the groove 1a, as shown in FIG.
a, and when the shielding plate 4 is fully inserted, the convex portion 4d of the tip portion 4C and the recessed portion 1d provided at the end of the groove 1a
are engaged with each other as shown in FIG.
Fixed to.

Further, since the engagement surface of the convex portion 4d is semi-cylindrical, the tip portion is thin and has a smooth curved surface, so that the shielding plate 4 can be easily attached and detached.

As described above, according to this invention, the shielding plate can be attached with a simple structure and without the need for screws.

[Brief explanation of the drawing]

FIG. 1 is a side sectional view showing a conventional terminal device. 2 is a perspective view showing a shielding plate used in the terminal device shown in FIG. 1. FIG. FIG. 3 is a developed plan view showing one embodiment of the terminal device according to this invention. Figure 4'' is a perspective view showing an embodiment of the shield plate used in the terminal device shown in Figure 3. Figures 5 and 6 are explanatory diagrams of this invention. Corresponding parts are given corresponding symbols, and 1 is a substrate, 1a is a groove, 1d is a recess, 2 is a terminal, 4 is a shielding plate, 4C is a tip, and 4d is a convex part.

Claims (1)

[Scope of utility model registration request] A board having a plurality of terminals, a groove provided between the terminals of the board, and a shielding plate inserted into the groove, a recess provided at an end of the groove, and a smooth curved surface that engages with the recess. A terminal device in which a certain convex portion is provided at the tip of the shielding plate, and the thickness of the tip is made thin.
