IPC: H01H13/04
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To improve the positional accuracy of a part which is mounted in the radial direction. SOLUTION: Leads 12 of a momentary switch 10 are formed, in such a way that their parts 12a existing in the thickness D of a substrate 40 overlap with substrate holes 41, when the momentary switch 10 is mounted on the substrate 40. Accordingly, when the leads 12 are inserted into the substrate holes 41 when mounting the momentary switch 10, the sidewalls of the substrate holes 41 are pressed and deformed by the parts 12a of the leads 12. As a consequence, no more clearance exists between the parts 12a and the substrate holes 41. In this way, when the leads 12 are clinched by a prescribed clinching angle (folded), the switch 11 will not rotate for its position.

Filed: 1988-04-12
Abstract: PURPOSE:To enable to dissociate core wires from each other smoothly, without lowering their adhesive strength by gluing plural insulated core wires through addition of a fixed amount of wax, lubricant of pure hydrocarbon nature to base polymer. CONSTITUTION:Plural insulated core wires are glued mutually in parallel by means of adhesive resin composition. Such material as polyamide polyvinyl butyral, compounded with amino resin, phenor resin, etc., for the purpose of improving the heat resistance is used as the base polymer of said adhesive resin composition. The compound amount of lubricant of pure hydrocarbon nature used singly or mixing more than two kinds and/or wax starys in a range from 0.1 to 20 pts.wt. to 100 pts.wt. of the base polymer. In the range of less than 0.1 pts.wt., the wire dissociation at the end and the surface lubrication cannot be sufficiently obtained, and in the range of more than 20 pts.wt., a lack of adhesive strength among core wires or a poor external appearance of a multi-core parallel lines of adhesion is incurred. Thus, adhesive strength among core wires becomes sufficiently high and core wires can be smoothly dissociated.
