Description

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

The remote control device for a car door lock shown in FIG.
Consisting of an intermediate connection part B between the vehicle body and the door, and a lock drive part C in the door, two vehicle body side conduction cables e 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 floor plate f. It is connected to a hole in a vehicle body panel h through a connector g connected to the end through the lower part, and the connector g connects one end of the door-side conductive cable k to the hole in the door panel j through an intermediate protective connector i. The other end of the door-side conductive cable k is connected to a bell crank lever m in the lock driving section C.
An indoor lock knob n is operatively connected to the bell crank lever m, and is also connected to a door lock p via an interlocking rod o. The wires in the operating handle d through the conductive cables e and k are biased by springs so that they automatically return to and hold the neutral position between the locking and unlocking positions.

In this configuration, when the driver tilts the remote control handle d of the operating section A forward from the neutral position, the bell crank lever m rotates counterclockwise via its spindle via the conduction cables e and k. The door lock p is locked via the movement lever o, and when the door is tilted backwards from the neutral position, the bell crank lever m is rotated clockwise and unlocked.

On the other hand, by manually operating the indoor lock knob n up and down, the door lock p is activated via the bell crank lever m.
The door-side conductive cable k is arranged so that the locking and unlocking operations by the indoor lock knob n and the locking and unlocking operations by the remote control handle d are performed independently. The end of the bell crank lever m is connected to the bell crank lever m via a play connection mechanism (not shown).

The present invention provides a novel structure for the intermediate connector 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 assembly and manufacturing process of a car, the fitting process begins with the car body and door separated, 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 points, and the conduction cable on the vehicle body side and the conduction cable on the door side are fixed in advance to the mounting holes of the vehicle body and the door by connectors provided at the ends of the outer cylinder, respectively. When installing the door to the vehicle body, both connectors are connected by a telescopic intermediate connector, and the wires of both conductive cables are connected within the intermediate connector, and each conductive cable is attached in the process of outfitting the vehicle body and door. This makes the work easier, the intermediate connection between both conductive cables is easy, and there is no hindrance to the opening/closing operation of the door, especially for the outer cylinder of the intermediate telescopic connector and the opposing conductive cable. This is an improved mechanism for coupling or releasing the coupling with the connector.

Embodiments of the present invention will be described below with reference to the drawings.
In Fig. 2, h is the center pillar of the vehicle body, j is the door panel, and the outer cylinder of one conduction cable e on the vehicle body side.

A part of the circular flange 9 is provided with a chamfered flat part 9a, and a rubber packing 13 that matches the shape of the flange is provided with a part adhered to the flat part 9a. In the inner support cylinder 11, an annular locking groove 11 on the outer periphery
a and a tightening tube 11b are formed.

In coupling the engaging bodies i ₁ and i ₂ , the metal ring 14 is crimped and fixed around the outer periphery of one end of the coiled spring 1, and then the metal ring 14 is attached to the support tube 5 of the engaging body i _1.
The metal band 15 is inserted into the tightening cylinder 5b and fixed by crimping. A protruding ring part 1a is formed at the outermost end of the other end of the coiled spring 1, and the protruding ring part 1a is inserted into the support cylinder ₁₁ of the engaging body i2 while being engaged with the metal ring 14. , the metal band 15 is crimped and fixed to the tightening tube 11b.

The bellows-shaped covering tube 2 is provided between the engaging bodies i ₁ and i ₂ in a state where the engaging flanges 2 a at both ends thereof are engaged with the annular locking grooves 5 a and 11 a and are bonded.

The door side connector l is integrally formed of a synthetic resin material, and the metal ring 1 is connected to the rear connecting pipe part 16.
By tightening step 7, it is connected in advance to the outer cylinder k' of the door-side conduction cable.

On the front side of connector l, there is a mounting hole for door panel j.
An engagement cylinder 18 that engages with j ₁ is formed, and the engagement cylinder 1
There are two locking protrusions 18 at opposing positions on the outer periphery of the tip of 8.
A is provided, and a narrow rotation prevention protrusion _18a1 is provided on the inside of the locking protrusion 18a in the axial direction, and the locking protrusion 18a is provided in the mounting hole _j1 of the door panel j. Passage permitting opening j ₂ and the rotation prevention protrusion 18a ₁
A locking opening j ₃ is connected to the connector l by inserting the engaging tube 18 into the mounting hole j ₁ from the inner surface of the door panel j while facing the locking protrusion 18a to the passage permitting opening j ₂ . Compress the sponge rubber packing 19 glued to the front surface of the door panel j, and when the locking protrusion 18a comes out to the front side of the door panel j, rotate it slightly to lock the rotation prevention protrusion _18a1 to the locking opening _j3 . The engaged state is ensured by the elastic restoring force of the packing 19.

The engaging cylinder 18 has a hook-shaped locking piece 1 provided on the engaging cylinder 10 of the engaging body i ₂ in the intermediate connector i.

In the annular engagement step 20, tapered lock release walls 20a are interposed at equal intervals so as to correspond to the three hook-like locking pieces 10b, and the hook-like locking pieces 10b are in the step 20. From the engaging body
By slightly rotating the _i2 portion in the circumferential direction, the hook-like locking piece 10b comes off the stepped portion 20, and can be pulled out as it is guided by the wall 20a to release the connection.
