Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a conductor connection terminal for connecting conductors for, for example, a duct.

(Prior art) This type of conductor connection terminal generally has a terminal body that has a groove that opens upward and into which the conductor to be connected is inserted, and a terminal body that overlaps and is tightened to push the conductor deep into the groove of the terminal body. It consists of a leaf spring that presses downward against the A conductor connection terminal having such a structure uses only a leaf spring to hold down the conductor, but the leaf spring has a risk of loosening and has a small tightening force, making it impossible to reliably connect the conductor.

(Purpose of the invention) The purpose of the invention is to increase the clamping force of the conductor,
Another object of the present invention is to provide a conductor connection terminal that can prevent a leaf spring from loosening.

(Structure of the invention) The conductor connection terminal of the invention is provided with a groove that is open on one side and into which two conductors to be connected are inserted, and a groove that is displaced toward the opening of the groove with respect to the conductor so as to cross this groove. A terminal body has a screw tap into which a screw is inserted to push the conductor deep into the groove, respectively, and a through hole through which a screw inserted into the screw tap is disposed overlapping the terminal body and is engaged with the conductor. The invention is characterized in that it consists of a hanging piece and a restraining spring.

In this way, the conductor is pressed deep into the groove of the terminal body not by the leaf spring but by the screws that are displaced relative to these conductors, so the clamping force on the conductor is large, and these screws are not pressed against the conductor. The tightening does not come loose because the effect of the leaf spring prevents it from loosening.

(Embodiment) An embodiment of the present invention will be described in detail with reference to the drawings. Figs. 1 to 3 show a conductor connecting terminal 10 according to the present invention, and this conductor connecting terminal 10 has one side open and connected. A substantially U-shaped groove 14 into which the conductor 12, 12' to be inserted is inserted;
The conductor 1 is displaced toward the opening 14a side of the
A terminal main body 20 (see FIG. 4) having two screw tabs 18 into which two screws 16 are inserted, which push the terminals 2 and 12' into the depths of the grooves 14, respectively. The through hole 22 through which the screw 16 screwed into the tap 18 passes, and the conductor 12,
12';
(See Figure 5). In the illustrated embodiment, the groove 14 of the terminal body 20 is stepped with its lower side ending closer to the upper side than the upper side. As can be seen from FIGS. 1 to 3 and 4A and 4B, the terminal body 20 also has a stopper pin 28 in the center of its upper plate portion, with which the tips of the conductors 12 and 12' abut. It has a pin hole 30 passing through it.
The lower end of this stopper pin 28 is engaged with the lower plate portion of the terminal body 20 to prevent it from coming off.

In this way, the conductors 12, 12' are pressed deep into the groove 14 by the screw 16 screwed into the terminal body 20, so the conductors 12, 12' The tightening of the conductors 12 and 1 is ensured, and the restraining spring 26
2', the conductors 12, 12' are fixed by the spring effect, and the screws 16
It can be seen that this prevents loosening.

(Effects of the invention) According to the invention, as mentioned above, the tightening force of the conductor is increased, so it can withstand a large tensile force, and the screws that tighten the conductor are prevented from loosening by the restraining spring, so the conductor The tightening will not loosen.
