摘要： PURPOSE:To prevent the reverse insertion of a tool by expanding the side sections of a support piece on the opposite side to a cutting edge, and hooking the support piece on a projection provided between notch sections on a terminal base. CONSTITUTION:Side sections 2e and 2e of a support piece 2b on the opposite side to a cutting edge 3 within a pair of support pieces 2a and 2b are expanded, and the horizontal width (i) in the longitudinal direction of the support piece 2b is made twice or more as large as the length (j) between centers of a notch section 12 and a projection 14, for example. When a tool is reversely set and thrust pieces 2c and 2d of support pieces 2a and 2b are to be inserted into notch sections 12 and 13 of a terminal base 8, the expanded side section end of the support piece 26 is hooked in contact with the upper end face of the projection 14, and the insertion of thrust pieces 2c and 2d into notch sections 12 and 13 is blocked.

摘要： PURPOSE:To miniaturize a tool and a terminal base by forming edge sections covering the other member on both sides of one member of a cutting edge and a tool main body. CONSTITUTION:The tip 3a of a cutting edge 3 is formed into a one-side edge, and the cutting edge 3 and a tool main body 2 are integrated while side faces 3a and 2c are butted. A support piece 2a on the cutting edge 3 side of the tool main body 2 is made thin to the extent possible, and the deficient strength of the support piece 2a reduced by thinning is reinforced by the cutting edge 3 or reinforced by itself. The width and thickness of receiving faces hit by the support piece 2a of a terminal base 8 and the tip 3a of the cutting edge 3 may be those corresponding to the thin support piece 2a, thus the terminal base 8 as well as the tool main body 2 can be miniaturized.

摘要： PURPOSE:To store electric wires with no congestion and immediately confirm electric wires at the time of reconnection, maintenance or inspection by combining one terminal board half body buried and held with terminals in multiple columns on the outside and protruded with multiple projections on the inside and the other terminal board half body having terminals in multiple columns on the outside likewise. CONSTITUTION:When covered electric wires 20 are to be connected, electric wires 20 are forcefully pushed into electric wire pinch sections 3a and 4a of U-slit terminals 3 and 4 from notches 16 of a terminal housing 14, covered portions of electric wires 20 are broken by the friction of edges of electric wire pinch sections 3a and 4a, and their core wires are pinched and fixed between both side faces of pinch sections 3a and 4a. Electric wires 20a-20n thus connected to terminals 3 and 4 are inserted into wire holes a1-an through the opening section of a terminal board end face A1 and extended to the outside through the opening section of a terminal board end face A2, thus electric wires 20a-20n are independently stored in wire holes a1-an in the maintenance state.

摘要： PROBLEM TO BE SOLVED: To provide a connector which can be simply and easily mounted even when there is a little positional error with respect to the mounting hole of a printed circuit board by giving a spring property to a plurality of fixing pins and fixing them to a housing and making them have positional flexibility. SOLUTION: A connector 1 is composed of one housing 2, a plurality of terminals 3..., one guide plate 4 and four fixing pins 5.... The pins 5 are composed of a horizontal part and a long leg piece and a short leg piece for fixation which are hung in parallel from both ends of the horizontal part and integratedly formed of a metal material of brass or the other. The long leg piece is projected downward from the lower surface of a side wall by a length capable of being inserted into a mounting hole 18 perforated so as to pass through a printed circuit board 17. The pins 5 to which a spring property is given and which are fixed, are firmly fixed to a housing main body 2a by the short leg piece without falling off. However, the long leg piece with respect to the board 17 is only fitted into a fitting groove, it can be moved in the lateral direction against its own spring property, so that the connector 1 may be easily mounted without being forced.

摘要： PURPOSE: To prevent U-shaped groove contact terminal parts from being folded and broken, by surrounding the U-groove press contact terminals projectingly provided on the upper surface of a connector main body from three ways by approximately U-shaped protective walls higher than the ends. CONSTITUTION: The upper surface of a connector main body 1 is formed into a step shape in the longitudinal direction and formed into an upper stage surface 4 and a lower state surface 5 between which there is a difference (a). A plurality of U-groove press contact terminals 6 for connecting electric wires are aligned and projectingly provided on the upper stage surface 4 in a line in the longitudinal direction at distances, and a plurality of U-groove press contact terminals 7, 8 are alternately aligned and projectingly provided on the lower stage surface 5 in two lines at distances. On the upper surface of the connector main body 1, protective walls 9 to 11 formed into approximately U shapes in plan view are projectingly provided on three surfaces on both ends in the width direction except for the front part of the main body 1 and on the rear end, and respective upper ends of the protective walls 9 to 11 are formed higher than the tips of the terminals 6 to 8 projecting from the upper stage surface 4 and the lower stage surface 5 of the main body 1. A plurality of notches 12a are provided on the protective wall 9 of the main body 1, so as to form comb-like wire aligning/wire holding part 12.
