Abstract

A connector for cable connection having good connection workability is provided. A waterproof connector for cable connection includes a housing having a cylindrical portion for allowing a cable to which a terminal is connected to be attached thereto, a waterproof bushing, a cover member, and a clamp member. In a state that the cable is attached to the housing through the cylindrical portion, a front portion of the bushing is elastically attached to the outer periphery of the cylindrical portion, and a rear portion of the bushing is elastically attached to the outer periphery of the cable. The cover member has an attachment portion for the clamp member. The clamp member attached to the attachment portion clamps the cable.

Claims

1. A waterproof connector for cable connection, comprising:

a housing having a cylindrical portion for allowing a cable to which a terminal is connected to be attached thereto;

a waterproof bushing;

a cover member; and

a clamp member, wherein;

in a state that the cable is attached to the housing through the cylindrical portion, a front portion of the bushing is elastically attached to an outer periphery of the cylindrical portion, and a rear portion of the bushing is elastically attached to an outer periphery of the cable;

the cover member has an attachment portion for the clamp member;

the clamp member attached to the attachment portion clamps the cable;

the clamp member clamps the cable by fitting a first clamp member and a second clamp member to each other;

the first clamp member and the second clamp member constitute a two-step fitting structure having a pre-fitting portion and a fitting portion;

the first clamp member and the second clamp member are attached to the attachment portion of the cover member in a state of fitting the pre-fitting portion; and

after the cable is inserted into and attached to the housing, the first clamp member and the second clamp member are fitted to each other by the fitting portion to clamp the cable.
