Claims (1)

[Claims for Utility Model Registration] At the center of both sides of the casing A, which is rectangular in plan and has the required depth, a vertical groove A1 is formed from the casing surface to a position closer to the casing opening edge. A step A2 is formed on the periphery at a depth position where the lid B is fitted and covered,
Inside the casing, a section A3 consisting of two partition walls is formed on the back side of the vertical groove A1, a section A4 is formed at a position perpendicular to the center of the section A3, and the following (I) is formed at the four corners inside the casing A. ) is formed, and an insertion hole A6 for the release button D described in (b) below is provided at the end of the compartment A3, penetrating through the surface of the casing A.
The orthogonal base of section A4, which is perpendicular to section A3, has the following
Slit A7 that holds the conductive plate E described in (c)
A vertical groove A8 is formed on the inner wall surface of the casing in correspondence with the slit A7, and a locking piece C2 is formed on the surface of the casing A, which is the contact point between the terminal fitting C housed inside and the conductive plate E. Positive and negative power wires, this is the feed wire, the positive and negative load wires, and this is the feed wire, are inserted into the power wire insertion holes H1 and H1 in the center of the
and a groove for the release button D in the release button insertion hole A6 of the casing A formed by drilling the feed wire insertion holes H2, H2, the load wire insertion holes H3, H3, and the feed wire insertion holes H4, H4. D2 is inserted toward the opening side of the insertion hole A6, and the slit E1 of the conductive plate E is inserted into the slit A7 and the vertical groove A8, and the horizontal surface D of the release button D is inserted.
3, the terminal fittings C are inserted and held so as to match both the circular arc recesses D4 of No. 3, the terminal fittings C are accommodated in each accommodation chamber A5 from the locking piece C2 side, and the sliding parts C5 are accommodated using each protrusion E2 of the conductive plate E as a guide, The rounded edges C4 of the locking piece C2 and the contact piece C3 are brought into contact with the conductive plate E, and the opening of the housing A is fitted and covered with a lid B, which locks the hook B1 formed on the back side of both vertical grooves A1. A terminal housing that is locked and fixed to part A9. (a) Both ends of the substrate C1 made of a strip of conductive metal with high spring properties are bent to face each other, one end is used as a locking piece C2, the other end is used as a contact piece C3, and the end of the contact piece C3 is curved with a roundness C4, and the substrate C
A terminal fitting C is formed by applying a sliding part C5 to the terminal fitting, leaving a part of the terminal fitting C5. (b) The whole is integrally molded with an insulating material, and the shape is approximately T-shaped from the front, and the width and thickness of the vertical surface D1 are set to match the insertion hole A6, and the end surface is formed with a groove D2, and the horizontal surface D3 The thickness of the terminal fitting C
A pair of recesses D4 are formed on the arc surface of the arc-shaped horizontal surface D3, and the distance between the recesses is determined by the distance between the pair of recesses D4 formed in the section A4. A release button D that extends at the same interval as the slits A7. (c) A highly conductive thin metal plate is formed into a rectangular shape with a slit E1 protruding to one side from the longitudinal end surface, and the depth and width of the slit are set by pressing the release button D.
The plate is sized to fit and allow stroke movement, and furthermore, a pair of protrusions E2 are provided on the end surface of the plate opposite to the opening of the slit E1 to protrude outward, and the distance between the pair of protrusions is adjacent to the accommodation chamber A5. A conductive plate E is made up of two sets: a conductive plate Ea extending equal to the distance between the sliding portions C5 of a pair of terminal fittings C accommodated in the same manner, and a conductive plate Eb having protrusions E2 protruding in opposite directions.
