Patent number: 5195910Abstract: A coaxial connector for use in connecting a first coaxial cable having a terminal processed in advance, to a second cable. The first cable comprises a central conductor, an insulator surrounding the conductor, a braid surrounding the insulator for shielding the same, and a sheath surrounding the braid for protecting the same. The coaxial connector comprises a sleeve section having an inner peripheral surface in close contact with an outer peripheral surface of the sheath, and a shell section integral with the sleeve section in coaxial relation thereto. A plurality of soldering bores are formed in the shell section and cooperate with each other to form passageway through which molten solder can pass to fill up an annular gap formed between an outer peripheral surface of the braid and an inner peripheral surface of the shell section.Type: GrantFiled: January 15, 1991Date of Patent: March 23, 1993Assignees: NEC Corporation, Hirose Electric Co., Ltd.Inventors: Hideyuki Enomoto, Ikujiro Mitani
