Abstract

Disclosed is a connecting device of a parking cable for an electric parking brake, which connects an actuator for the electric parking brake with a parking cable. The connecting device includes a connector and a reaction force member. The connector includes a small diameter section having one side into which an outer peripheral surface of the parking brake is inserted, a large diameter section that extends from the small diameter section to have a diameter larger than that of the small diameter section, an axial cutout slit axially formed through upper and lower surfaces of an outer peripheral portion of the large diameter section such that protrusions circumferentially protruding from the actuator are inserted into the axial cutout slit through the large diameter section, a circumferential cutout slit that extends from an inner end of the axial cutout slit in a circumferential direction, and a cutout groove that axially extends from the circumferential cutout slit. The reaction force member is inserted into the large diameter section to press the protrusions such that the protrusions are seated in the cutout groove through the axial cutout slit and the circumferential cutout slit. According to the connecting device, the assembly work is facilitated, so the assembly efficiency can be improved and connection work using the connector can be easily performed.

Claims

1. A connecting device of a parking cable for an electric parking brake, which connects an actuator for the electric parking brake with a parking cable, the connecting device comprising:

a connector; and

a reaction force member,

wherein the connector comprises;

a small diameter section having one side into which an outer peripheral surface of the parking brake is inserted;

a large diameter section that extends from the small diameter section to have a diameter larger than that of the small diameter section;

an axial cutout slit axially formed through upper and lower surfaces of an outer peripheral portion of the large diameter section such that protrusions circumferentially protruding from an outer peripheral surface of an end of the actuator are inserted into the axial cutout slit through one side of the large diameter section;

a circumferential cutout slit that extends from an inner end of the axial cutout slit by a predetermined length in a circumferential direction; and

a cutout groove that axially extends from the circumferential cutout slit,

and wherein the reaction force member is inserted into the large diameter section of the connector to press the protrusions of the actuator such that the protrusions are seated in the cutout groove through the axial cutout slit and the circumferential cutout slit.

2. The connecting device of claim 1, wherein the reaction force member includes one selected from the group consisting of a spring, rubber, corrugated rubber and a leaf spring.
