Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an intermediate connection mechanism for a conducting cable in a remote control device for a vehicle door lock.

The remote control device for a car door lock shown in FIG. 1 consists of an operation part A in the driver's seat of the car, an intermediate connection part B between the car body and the door, and a lock drive part C in the door.
The two vehicle body side conduction cables for transmitting motion to the left and right doors of the rear seat connected to the remote control handle d are connected to the vehicle body floorboard f.
The connector g is connected to the hole in the vehicle body panel h through the lower part of the connector g connected to the end thereof, and the connector g is connected to the hole in the door handle j via the intermediate protective connector i at the door side. One end of the conductive cable is connected to a connector l holding the conductive cable, and the other end of the conductive cable on the door side is connected to the mouth and hook drive unit C or to the bell crank.

The bell crank lever m has an indoor opening/socket door (
operatively connected to the door lock p via the interlocking rod 0.
connected to. The wires inside the cables (operation) are biased by springs so that they automatically return to the neutral position between the locking operation position and the unlocking operation (upright position) and are held there.

In this configuration, when the driver tilts the remote control handle d of the operating section A forward from the neutral position, the conduction cable 6. (The door lock P is locked through the interlocking rod 0 by rotating counterclockwise through its pivot shaft, and when it is tilted backwards from the neutral position, the hell crankshaft is activated.) The s-m rotates in the direction of the hour hand and is unlocked.

On the other hand, by manually operating the indoor lock knob n up and down, the door opening/pocket p can be locked or unlocked via the bell crank lever m, and the locking and unlocking operations by the indoor lock knob n and the remote control are performed. The end of the door conduction cable is connected to the bell crank lever m via a play connection mechanism (not shown) so that locking and unlocking operations using the handle d can be performed independently.

The present invention provides a novel structure for the intermediate connection mechanism between the vehicle body-side conductive cable and the door-side conductive cable between the door and the vehicle body in such a remote control device for an automobile door lock.

In the car assembly and manufacturing process, the car body and door are separated before entering the silk manufacturing process, so as mentioned above, the conduction cable is separated into the car body side and the door side, and is assembled into the car body and door separately. , each end must be connected when the door is attached to the vehicle body.

The present invention has been made with attention to the above-mentioned points, and includes a conductive cable on the vehicle body side that is fixed in advance to the mounting hole number 4 of the vehicle body by a connector provided at the end thereof, and an extendable intermediate connector to the connector. This method facilitates the installation of each conductive cable in the car body and tena silk manufacturing process, facilitates the intermediate connection of both conductive cables, and ensures that there is no hindrance to the opening/closing operation of the door.
