Description

[Detailed description of the invention] (Field of industrial application) The purpose of this invention is to freely attach and detach terminals fixed to a terminal board at predetermined intervals and elastic clamping pieces fixed to an insulating plate with lead wires. This invention relates to a connection device between a fixed terminal and a lead wire.

(Problem to be solved by prior art and invention) Conventionally, in order to connect the terminal pieces of a terminal board and the lead wire ends, the lead wire ends were fixed with screws screwed into each terminal piece, or each lead wire end was An elastic clamping piece connected to the terminal is fitted and fixed to the terminal (for example,
No. 27686). Therefore, the screws on the terminal board must be screwed in and screwed out, or the ends of the lead wires must be processed, which limits the working position or takes a long time. There was also the problem that it was easy to make mistakes in connection in places where the wires were gathered and fixed.

(Means to Solve the Problem) However, this invention fixes the corresponding lead wire ends for each predetermined number of elastic clamping pieces to the same insulating plate, and then clamps the elastic clamping pieces to the corresponding terminal pieces. Since the wires are connected, the work can be completed instantly in both cases of connection and disconnection, and there is no risk of making a connection mistake.Furthermore, the above-mentioned problems of the conventional wires have been solved, such as there are no restrictions on the work place when attaching the lead wires. That's what I did.

That is, in this invention, in correspondence with a plurality of fixed terminals fixed to a terminal board, a plurality of elastic clamping pieces that can be clamped and fixed to one side of an insulating plate are fixed to one side of an insulating plate with independent screws, and the other parts of the insulating plate This is a connection device for a fixed terminal and a lead wire, in which one end of a screw that fixes the elastic clamping piece is projected from a surface, and independent lead wire ends are fixed to the part with nuts.

The elastic clamping piece mentioned above is composed of two, three or four conductive metal pieces facing each other in a cantilevered manner.

(Function) According to this invention, a plurality of elastic clamping pieces are fixed to the insulating plate with screws, and the ends of the lead wires are fixed to the screws. The fixed terminal and lead wire can be connected at the same time.

(Example) That is, to explain this invention in terms of an example, partition pieces 2, 2 are provided upright at equal intervals on the upper surface of a rectangular insulating plate 1 (for example, made of synthetic resin), and each of the partition pieces 2, 2 on the lower surface is erected.
2, to the position corresponding to the side elastic clamping piece 3,
The horizontal portions 3a of No. 3 are fixed with screws 4, 4, respectively. Therefore, the screws 4, 4 protrude between the partitions 2, 2 on the upper surface of the insulating plate 1. Screw the nuts 5, 5a onto the protruding parts of the screws 4, 4, respectively (the nuts 5 are for fixing the clamping pieces 3, 3;
is for fixing the terminal 7 of the lead wire 6).

By inserting the terminal 7 of the lead wire 6 between the nuts 5 and 5a and tightening the nut 5a, the terminal 7 can be fixed. On the other hand, a terminal board 9 is fixed to one side of the electrical equipment 8, and the terminal board 9 has a plurality of terminals 10.
is fixed with screws 11. Each terminal 10 of the terminal board 9 and each elastic clamping piece 3 of the insulating plate in the above
are manufactured with corresponding positions and dimensions, so the elastic clamping piece 3 is attached to the screw 1 of the terminal 10.
1 can be fitted and fixed. Therefore, a plurality of lead wires can be connected simultaneously. In the above embodiment, the elastic clamping piece 3 is made of two metal pieces facing each other, but the point is that the elastic clamping piece 3 needs only to be firmly connected to the screws and/or terminals of the terminal board. Of course, the number is not limited to two, but may be three or four. Further, it is preferable that the free end of the metal piece has a shape that allows it to come into close contact with the screw head or the abutting part of the terminal.

Conventionally, a connector is known in which a coupling piece is brought into contact with an insulating plate and the coupling piece is inserted into a connection hole of a corresponding connector. No technique for connecting lines has yet been proposed.

(Effect of the invention) That is, according to this invention, elastic clamping pieces for a plurality of terminals are fixed to the insulating plate in correspondence with each other, and each of the elastic clamping pieces and each lead wire end are electrically connected. Therefore, there is an effect that each lead wire can be fixed to or removed from each terminal of the terminal board through the elastic clamping piece. Moreover, it has the effect of improving work efficiency and eliminating any mistakes in connection between lead wires and terminals.
