Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to improving the safety of a terminal cover of a terminal device for electrical equipment.

[Conventional technology]

Figures 4 and 5 show a conventional terminal device. In the figures, 1 is the outer shell (main body) of an electrical device having multiple operation ports 2 connected to each other at the top and side. 2 includes wire connection parts 6 each consisting of a terminal fitting 3, a wire presser 4, and a terminal screw 5.
The terminal screw 5 can be operated with a screwdriver through the upper opening 11 of the operating port 2, and the electric wire 7 can be inserted through the side opening 12. 8 is attached to the outer cover 1 with screws 9 in order to prevent electric shock from accidentally touching the wire connection part 6, and the operation port 2
The upper opening 11 of the operation port 2 is completely closed by an insulating terminal cover that covers the operation port 2, and the side opening 12 is closed with an opening L necessary for the insertion of the electric wire 7 remaining.

[Problem that the invention attempts to solve]

In the conventional terminal device as described above, the opening amount L is a single value, so when the opening amount L is determined assuming that two electric wires 7 are to be connected as shown in FIG. When the number of electric wires 7 is reduced to one as shown in FIG. 6, the amount of opening becomes too large, resulting in an unfavorable situation in terms of safety.

This invention was devised to solve such problems, and provides a terminal device that can ensure an appropriate opening amount even if the number of connected wires changes.

[Means for solving problems]

The terminal device according to this invention is provided with a terminal cover having an elastic tongue that fits into the operation opening of the main body,
This ensures that the live part can be covered even if the number of connected wires changes.

[Effect]

In the terminal device according to this invention, a terminal cover having an elastic tongue piece fits into each operating port, and even if the number of connected wires changes, the live part is reliably covered, improving safety.

〔Example〕

An embodiment of this invention will be described below.
In FIGS. 1, 2, and 3, 1 is an outer shell (main body), and a wire connection part 6 consisting of a terminal fitting 3, a wire presser 4, and a terminal screw 5, as in the conventional one.
It has an operation port 2 that accommodates. Reference numeral 8 denotes a terminal cover of this invention, which is provided with elastic pieces 8a that correspond to each operation port 2 of the outer shell 1 and fit into each operation port 2. That is, the elastic tongue piece 8a is provided in an inclined manner so as to cover both the upper opening 11 and the side opening 12 of the operating port 2.

In the terminal device configured as described above, when two electric wires 7 are connected to the electric wire connection part 6 as shown in FIG.
covers the connection part 6 in a state where it is in contact with the upper electric wire 7. Further, as shown in FIG. 2, even when one electric wire 7 is connected to the electric wire connection part 6, the elastic tongue piece 8a of the terminal cover 8 is in contact with the electric wire 7, and the connection part 6
will cover.

[Effect of idea]

As described above, according to this invention, a terminal device with high safety can be obtained because the operating port is covered with a terminal cover equipped with an elastic tongue according to the change in the number of wires connected to the connection part. effective.

[Brief explanation of drawings]

Fig. 1 is a partially cutaway side view showing one embodiment of this invention, Fig. 2 is a partially cutaway side view showing different usage conditions, Fig. 3 is a perspective view of the terminal cover, and Fig. 4 is a conventional 5 is a partially cutaway side view, FIG. 6 is a partially cutaway side view showing different usage conditions, and FIG. 7 is a perspective view of the terminal cover. In the figure, 1 is the outer cover (main body), 2 is the operation port, 3 is the terminal fitting, 4 is the wire presser, 5 is the terminal screw, 8 is the terminal cover, 8a is the elastic tongue piece, 11 is the upper opening, 12
is the side opening. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] An electric appliance that houses the wire connection parts consisting of terminal fittings, wire holders, terminal screws, etc., has an operation opening with multiple openings connected above and on the sides, and a terminal cover that covers part of the upper and side parts of the operation opening. What is claimed is: 1. A terminal device for electrical equipment, comprising a terminal cover having an elastic tongue that fits into each of the operation ports.
