Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a connecting device that is improved so that a plurality of electrical conductors each having a rectangular cross section can be easily connected by adjusting the contact pressure.

Multiple electrical conductors with rectangular cross sections are generally connected by tightening bolts and nuts or by using a knife switch. When it is necessary to increase the contact pressure of the switch, not only is a large opening/closing operation force required, but there is also the drawback that the contact surface of the switch may be damaged during the opening/closing operation.

In order to eliminate the above-mentioned drawbacks, the object of this invention is to provide a connecting device for electrical conductors having a rectangular cross section, which allows easy connection by adjusting the contact pressure.

Hereinafter, embodiments of this invention will be described based on the drawings.

1 and 2 show an electrical conductor connection device according to this invention. The connecting device in these figures shows two electrical conductors 1 of rectangular cross section.
is fixedly disposed with an electrical insulator 2 interposed therebetween, and two plate-shaped electrical conductors 4 with an electrical insulator 3 interposed therebetween are connected at their tips straddling both sides of the conductor 1. . The conductors 1 and 4 are connected by pressing with a tong mechanism 5, and when the tong mechanism 5 is loosened, the tip of the conductor 4 is released from both sides of the conductor 1 as shown in FIGS. 3 and 4. It's summery.
The tong mechanism 5 includes a pair of lever members 7 that rotate around both ends of a support rod 6, and the lever members 7.
It consists of an operating section 8 provided at one end, and an operating section 9 that engages with the other end of the lever member 7 to press the conductors 1 and 4. The operating section 8 is a lever member 7
A pair of operation plates 8a rotatably connected to one end of the
and a groove-shaped stopper 8 that engages with the tip of a pin 8b commonly connected to the tip of the operation plate 8a.
c, and an operating lever 8d attached to the tip of one operating plate 8a. The acting portion 9 is formed by interposing an electrical insulator 9a, and a spring 9b formed by stacking a plurality of bell springs is connected to the conductors 1 and 4.
The contact pressure can be adjusted.

According to the embodiment described above, the contact pressure between the conductors 1 and 4 can be appropriately adjusted by adjusting the spring action of the spring 9b, and the pair of operating plates 8a can be held in a buckling state as shown in FIG. By doing so, it is possible to reliably press and connect.
From this state, as shown in FIG.
By operating in the direction of the P arrow and moving the action part 9 in the direction of the Q arrow, the conductor 4 can be released from both sides of the conductor 1 and easily removed, and by operating in the reverse order, the conductor 4 and 1 can be connected with one touch.

As described above, according to this invention, in the connection device for a plurality of electrical conductors having a rectangular cross section, the connection is made by pressing with a tong mechanism equipped with a spring that adjusts the contact pressure of the conductors. Conductors can be reliably connected with a high contact pressure, and the tong mechanism can be operated with a single touch to connect conductors.
The effect is that removal can be easily performed.
