摘要： PURPOSE:To make a reversal point constant and facilitate assembling by pinching a sheet of a thin spring material to form a reversal spring with the preset shape and pushing it to reverse. CONSTITUTION:Both side leg sections 9a and 9b and a center leg section 9c of a reversal spring are formed by punching a thin spring material, and a tip 9d is tapered. A projection 9e is formed by step bending at rear end sides of both side leg sections, and both side leg sections 9a and 9b are brought near to each other on the same plane. Dish spring-shaped curved faces with a large curvature are formed on notch sections 9f and 9f provided on outsides of both side leg sections 9a and 9b respectively. This curved quantity is made constant, thus the reversing operation at the constant reversal point is performed by pushing the center leg section 9c. The reversal spring 9 is incorporated in a contact mechanism section, and the center leg section 9c is pushed by the action of a heat element 1 to perform the reversing operation.

摘要： PURPOSE: To provide an insert ring, which easily copes with different mounting screw diameter, hardly generate resin leakage and is of low production cost, and its production method. CONSTITUTION: An insert ring 13 is embedded in the mounting hole of resin formed part so as to encircle the mounting hole as an insert member, is made of the metal sheet drawings formed to pot shape and is provided with a fall-off stopper part 14, in which the outer wall face of metal sheet curved to S shape is integrated to formed resin and a through hole of diameter (d) corresponding to mounting screw diameter in the bottom sheet part of pot shape. Further the insert rings 13 are structured so that an outer diameter D of fall-off stopper part and a height H vertical thereto are approximately same but a through hole (d) only is made of plural different kinds corresponding to a mounting screw diameter, the height H is formed, by a fixed dimension, larger than the height of mounting hole part of the resin formed part to be formed for insert.

摘要： PROBLEM TO BE SOLVED: To eliminate the necessity of bending L-shaped conductors further after being inserted into a through hole of a zero phase current transformer, and solve a problem such as an insulating member is damaged by sandwiching a ZCT to detect a leakage current by two unitized members by integrally molding plural conductors from a resin, and constituting so that the two unitized members are electrically connected to each other in a through hole of the ZCT. SOLUTION: Divided parts of a conductir R:1b, a conductor S:2b and a conductor T:3b are formed as the conductor R end lx, the conductor S end 2x and the conductor T end 3x formed into a shape fittable to the mutually opposing divided parts, and are molded into a single part by a resin B:8b while keeping a mutual clearance. After the conductor ends 1x, 2x and 3x and the conductor ends 1y, 2y and 3y are fitted and joined together by using, for example, an arc spot welder, a joining part is insulated by slicone and expoxy or the like. They can be fitted to a prescribed receptacle by an output pin 31p, and three conductors of RST can be always arranged in a fixed position. An insulating material can be omitted, and external appearance and insulating performance are also improved.

摘要： PURPOSE:To easily fix leaf springs of a lower part link for preventing coming- off of a pin which connects upper/lower part links of a toggle link. CONSTITUTION:Leaf springs 5 for preventing coming-off of a connecting pin of an upper part link, not shown, inserted into U-shaped grooves 4 of a lower part link 2 are right/left integrally connected by a back plate 6, formed into a U shape and fixed to a back plate 2b of the lower part link 2 by calking protrusions 2c. In this way, calking work is simplified as compared with the case that the right/left leaf springs 5 are separately fixed to arms 2a of the lower part link 2.
