JPS5821084Y2 - Tightening terminal device - Google Patents

Description

[Detailed description of the invention] The present invention relates to a terminal device that tightens and connects electric wires by tightening screws. When inserting the electric wire, before tightening the screw, the electric wire is temporarily secured, so that the electric wire can be connected while the screw is being tightened. The purpose is to ensure that no one is left out.

Referring to the drawings shown below as an embodiment of the present invention, reference numeral 1 denotes a terminal metal fitting, which is composed of an upper plate 2 and a lower plate 3 corresponding to the upper plate 2.

Note that the upper and lower plates 2.3 are connected by side plates 4.

Reference numeral 5 denotes a tightening screw screwed into the upper plate 2, 6 an insertion opening for the electric wire T provided in the side plate 4, and 7 an insulating material stand to which the upper plate 2 is fixed.

Reference numeral 8 denotes a horizontal U-shaped presser foot made of conductive spring material, consisting of upper and lower pieces 9 and 10, with its tips 9a and 1 ob facing the wire insertion port 6, and terminal fitting 1. lower plate 3
is interposed between the upper and lower pieces 9 and 10.

Further, the upper piece 9 and the lower plate 3 are close to each other so as to sandwich the electric wire T when the electric wire T is inserted.

Further, the tip 9a of the upper piece 9 is curved upward to facilitate insertion of the electric wire T.

Next, to explain the tightening order of the electric wire of the present invention, Fig. 1 shows a state in which the electric wire T is not connected. Insert between the top piece 9 and the top piece 9.

In this case, the screw 5 is still tightened and the button does not press, but due to the springiness of the upper piece 9 of the presser foot 8, the electric wire T will not come out even if you release your hands holding it with the lower plate 3. be.

Thereafter, as shown in FIG. 3, the upper piece 9 of the presser foot 8 is held down by tightening the screw 5 to complete the tightening.

In the present invention, the horizontal U-shaped presser foot 8 is made of a conductive spring material, and is made of a conductive spring material, and the upper and lower pieces 9 and 10 are biased with a spring force in a direction in which the tips of the presser foot 8 approach each other. 9,100
The lower plate 3 of the terminal fitting 1 is interposed between the upper and lower parts 9 and 10 with the tip facing the wire insertion port 6 side, and the lower plate 3 of the terminal fitting 1 is inserted between the upper piece 9 of the presser foot 8 and the lower plate 3 of the terminal fitting 1. Since the electric wire T is placed in the same position, when connecting the electric wire T, the electric wire T can be temporarily fastened before tightening the screws.Therefore, there is no difficulty in operating the screwdriver while holding the electric wire T by hand, improving work efficiency. Moreover, since the presser foot 8 is made of a spring material, it has the effect of increasing the contact pressure of the electric wire and preventing the screw from loosening due to the repulsive force.
