INSULATING BUSH MADE OF THERMOPLASTIC MATERIAL AND PRODUCTION METHOD THEREFOR

摘要

An insulating bush made of a thermoplastic material comprises an insulating housing (10), a center conductor (20), and a shielding mesh (30). The insulating housing (10) is molded by casting a thermoplastic material. A through hole (11) is provided in the center in an axial direction. An annular inner cavity (13) of the insulating housing is formed between an outer side surface (12) of the through hole (11) of the insulating housing (10) and an inner side surface (16) of the insulating housing (10). The center conductor (20) is embedded into the through hole (11) of the insulating housing (10). The shielding mesh (30) is disposed in the annular inner cavity (13) of the insulating housing (10). The shielding mesh (30) is encircled by the insulating housing (10) completely or partially. The shielding mesh (30) encircles the center conductor (20). The insulating bush is compact in structure, light in weight, and convenient to mount. By using a thermoplastic material as an insulating housing, the problem of pores and small cracks is easily resolved. The plastic is high in cooling and solidifying speed. Moreover, the thermoplastic material can be repeatedly used after being heated again, thereby achieving the good recycling property, eliminating the solidifying process, shortening the production time, and improving the production efficiency.
