Encapsulating resin



PROBLEM TO BE SOLVED: To enable the satisfactory performances to be exhibited by making encapsulating resin of an olefin base resin for the purpose of cost down. SOLUTION: A bobbin 2 is molded with resin. The resin is preferably the same as an encapsulating resin 5. Next, solenoid coils 3 are made by winding a wiring material a specific number of turns around the bobbins 2. Next, a terminal 4 is caulk.pressure fixed in a wire rod end of solenoid coil 3 to be connected. Successively, respective members (bobbins 2, solenoid coils 3 and terminal 4) are encapsulated with the encapsulating resin 5. At this time, the encapsulating resin 5 is specified to be polypropylene of a flow rate exceeding 0.5cc/sec and of a melting point exceeding 120°C by the Koka type flow test. Through these procedures, the title encapsulating resin exhibiting satisfactory performances capable of making cost down feasible can be manufactured. COPYRIGHT: (C)1997,JPO
