- An object of the present invention is to provide a terminal block that can more effectively prevent loosening of a screw in a holding portion.
- the above-mentioned object is to provide a terminal block having a holding portion for holding a wire end of an electric wire and a base body to which the holding portion is attached, wherein the base body has a holding surface on which the wire end is held.
- a base portion formed and two plate portions, each having a circular screw hole formed thereon and arranged so as to overlap with each other at a position facing the holding surface, wherein the holding portion includes: A sandwiching plate member disposed between the sandwiching surface and the two plate portions and sandwiching the wire end between the sandwiching surface and the two screw holes of the two plate portions; And a screw for pressing the plate member in the direction of the clamping surface, wherein the screw has a cross-section of a threaded shaft whose major axis is a diameter of a screw hole of the two plate portions.
- the two plate portions are formed when the wire ends are pinched, and are advanced when the screw is tightened.
- a force in the opposite direction acts on the two plate portions through the screw, the center positions of the two screw holes can be shifted from each other according to the force, and
- the terminal block is elastically connected to the base so that the centers of the two screw holes are arranged substantially coaxially.
- the wire end of the electric wire is attached to the base body.
- the holding plate member is pressed to press the wire end. Is sandwiched between the clamping surface and the clamping plate member.
- the two plate portions on which the screws are mounted are tightened by tightening the screws in the direction opposite to the direction in which the screws advance, that is, It works in the direction from the inside of the base body to the outside.
- the cross section orthogonal to the axial direction of the screw has an elliptical screw.
- the screw is squeezed until the wire ends are clamped with sufficient pressure, and after the ellipse of the screw and the ellipse formed by the screw holes of the two plate parts match, the screw To rotate in the slack direction, it is necessary to return the elliptical screw hole formed by the screw holes of the two plates to a circular shape again.

- FIG. 4 is a cross-sectional view for explaining the operation of the conventional terminal block.
- FIG. 5 is a top view of the table main body for describing how the positions of the sides 4a and 4b of the table main body in the embodiment of FIG. 1 are shifted.
- BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of a terminal block to which the present invention is applied will be described with reference to the drawings.
- the terminal block of the present embodiment includes a base body 4 that forms a space into which a conductor such as a wire end is inserted, and a conductor that is inserted into the space. And a clamping portion 10 for clamping to be pressed against the clamping surface 4c at the lower inside.
- the base body 4 is formed, for example, by bending an elongated metal plate-like member at four points at right angles in the same direction, and overlapping the first side 4a and the last side 4b. Further, the side portions 4a and 4b are provided with circular screw holes 4a 'and 4b' which are threaded so as to match the screw shaft portion lb.
- the holding portion 10 is connected to the screw 1 composed of the screw head 1a and the screw shaft 1b, and to the lower end of the screw shaft 1b so as to move up and down in conjunction with the axial movement of the screw 1. It has a clamping plate member 3 and.
- the screw 1 is attached to the base body 4 by screwing into the two screw holes 4a 'and 4b' provided on the sides 4a and 4b one after another.
- the lower end of the screw shaft portion 1 b protruding downward is connected so as to be in contact with the holding plate member 3.
- the screw shaft portion lb of the screw 1 is configured such that the cross-sectional shape 1c in a direction orthogonal to the axial direction is elliptical.
- the major axis R2 of the elliptical shape has the same length as the diameter of the screw holes 4a and 4b ', and the minor axis R1 is smaller than the major axis R2.
- the screw 1 is, for example, a normal metal screw made by a conventional manufacturing method, that is, a screw with a circular cross-section perpendicular to the axial direction. It can be created by applying pressure in the direction perpendicular to and deforming it.
- the cross-sectional shape 1c is an elliptical shape or an ellipse regardless of the ratio between the minor axis R1 and the major axis R2, Screw loosening can be more effectively prevented than with conventional terminal blocks. Therefore, in the present invention, the sectional shape 1 c
- the shape of the ellipse is not specifically limited, and if the major axis R 2 is the same length as the diameter of the screw holes 4 a ′ and 4 b ′, a value smaller than the length is used. Within the range, the value of the minor axis R 1 can be determined as appropriate.
- the wire end which is the conductor portion of the electric wire
- the screw 1 is squeezed in that state, whereby the wire is removed. Hold the end and fix it.
- the wire end and the terminal block are connected via the conductor.
- the pressing force is applied to the clamping plate member 3 and, at the same time, anti-cracking occurs in the direction opposite to the pressing force.
- the anti-power works to push the sides 4 a and 4 b of the base body 4 upward through the screw 1.
- the sides 4 a and 4 b are part of the base body 4 and are fixed at one side. Therefore, the entire side does not move upward, and the connected side or the side 4 c ′ on both sides of the clamping surface 4 c is used as a rotation axis, and the side 4 a, 4 Deform b to open outward. Then, the center positions of the two circular screw holes 4a 'and 4b' of the sides 4a and 4b which were originally coaxial are shifted from each other, and as shown in FIG. An attempt is made to form an elliptical screw hole 1 c ′.
- the base body 4 is made of metal, a force that constantly presses the screw 1 downward is exerted by the panel elastic force acting on the deformation of the sides 4a and 4b.
- the end which can more effectively prevent the loosening of the screw 1 of the holding portion 10 of the terminal block can be prevented.
- a child stand can be provided.
- the terminal block which can prevent the loosening of the screw of a clamping part more effectively can be provided.
