Description

[Detailed Description of the Invention] The present invention provides a mounting structure for a cable such as a meter cable in an automobile speedometer, and more specifically, the speedometer cable is fixed in advance and the speedometer body is inserted into it from the passenger side. The present invention relates to a mounting structure for a meter cable, etc., in which a cable and a meter body are connected by fitting together.

The conventional speedometer cable mounting structure is to fix the meter body 2 to the instrument panel 1 provided on the vehicle body with screws 3, 3, as shown in Figure 1, and insert your hand into the back side of the body 2 to connect the 1 or )\ Screw the cylindrical screw-type connector cap 6a or one-touch type connector cap 6b, which is fitted without rotation to the outer casing 5 at the tip of the meter cable 4 shown in the figure, to the center of the meter body 2. Fit or rotate 900 times to engage and connect the meter cable 4.
A key shaft 8 at the tip of an inner flex wire 7 that transmits internal rotation was connected to the drive unit within the meter body 2.

Note that 40 indicates a dash panel, and 42 indicates a front window.

However, when installing the meter, ■Meter 1 body 2
Fix it to instrument panel 1.

■Attach the meter cable 4 to the meter body 2.

■Remove the meter body 2 from the instrument panel 1.

2 operations are required, which complicates the process, and in particular, the above operation (2) must be carried out by inserting one's hand under the narrow instrument panel 1 as shown in Fig. 1A. The work is cumbersome as it is necessary to turn the square hole of the magnet shaft of the drive section of the meter body 2 to align its rotational position with the direction of the key shaft 8. This was a waste of space because it required space to insert the .

In order to eliminate this drawback, the present invention fixes the meter cable 4 to the instrument panel 1, and then attaches the meter body 2.
is fixed by fitting into a key mounting hole provided on the back side of the meter body 2, or conversely, a key is provided on the back side of the meter main body 2, and this key shaft 8 is fitted into a key mounting hole provided at the tip of the meter cable 4. This makes it possible to more easily and reliably fix the meter cable 4 to the instrument panel 1.

An embodiment of the present invention will be described in detail below with reference to FIGS. 2 to 6.

As shown in the second figure, a cable fixing bracket 10 is fixed to the back side of the instrument panel 1.

As shown in FIG. 3A, a guide casing 11 with a conically open end is fixed to the tip of the outer casing 5 at the tip of the meter cable 4, and the center portion of the guide casing 11 is fixed to the base of the guide casing 11. A disk-shaped first flange 12 that bulges out spherically toward is fixed, and a second flange 13 is fixed to the guide casing 11.
and the flange 12 so as to be slidable on the base, and the second flange 13 is resiliently repelled toward the first flange 12 by the coil spring 14.

A cylindrical joint inner 15 is fixed to the tip of the inner flex wire 7.
A key shaft 8 having a square cross section is fitted into the tip of the key shaft 8 so as not to rotate but to be able to slide in the axial direction. A spring 11 is inserted which is resilient in the direction of engagement.

As shown in FIG. 3, bushes 18° 1B and 19 are provided approximately at both ends and in the middle of the outer circumferential surface of the joint inner 15, and bushes 18° 1B and 19 are provided on the outer circumferential surface of the joint inner 15 for lubrication between the bushes and the outer casing 5. A pair of diagonal grooves 20 and 21 are provided for feeding the grease g toward both ends during rotation.

Note that the center bushing 19 may be omitted.

As shown in the second and fourth figures, the bracket 10 has a rising portion 10', and the guide casing 11 and the flange 13 of the outer casing 5 are provided at this rising portion.
A circular hole 22 into which the guide casing 11 is fitted and a small circular hole 23 into which the cylindrical portion 11' of the guide casing 11 is fitted are continuously bored.

Next (I will explain how to assemble this device.

When the guide casing 11 at the tip of the meter cable 4 shown in FIG. 3A is inserted into the circular hole 22 from the left side in FIG. The base 11' of the guide casing 11 is shifted downward and the base portion between the first and second flanges 12 and 13 is fitted into the small circular hole 23, The bracket 10 is held between the flanges 12 and 13, and the cable 4 is firmly and stably fixed to the bracket 10.

Next, the fixed stem bush 24 protruding from the rear surface of the meter body 2 and the rotating magnet shaft 25 are attached to the fifth
As shown in the figure, the guide casing 11 is inserted into the conical opening, and the main body 2 is fixed to the instrument panel 1 by means of pins 3, 3.

Therefore, the joint inner 15 is the bush 18, 1B.
, 19t, so that the key shaft 8 and the key hole 26 are arranged to face each other in the linear direction.

At this time, the direction of the key shaft 8 is set to the magnet shaft 25.
When the key shaft 8 fits into the key hole 26 having a square cross section as shown in FIG. 6, the key shaft 8 fits into the key hole 26, but when it does not match as shown in FIG. It is pushed into the joint inner 15 against the elasticity of the spring 17.

However, when the car moves, the transmission rotates the key shaft 8 via the inner flex wire 7 and the joint inner 15, and if the direction matches the key hole 26, the key shaft 8 is pushed into the key hole 26 by the elasticity of the spring 17. The inner flex wire 7 is connected to the magnet shaft 25.

During the rotation of the inner flex wire 7 and the joint inner 15, the grease g between the joint inner 15 and the outer casing 5 is sent to the bushes 1B and 1B at both ends by the diagonal grooves 20 and 21, so that the grease g is It lubricates the rotation of the joint inner 15 and rotates it smoothly, eliminating the risk of contact and preventing the generation of noise during rotation.

As an application example of the present invention, the movable flange 13 may be placed on the opposite side of the flange 12, and the bracket 10 may be sandwiched between the flanges 12 and 13.

In addition, both flanges are integrally formed to form the guide casing 1.
1 in a slidable manner, and when installed, spring 1
4 may always urge the guide casing 11 against the meter body.

Furthermore, the bracket 10 may be provided with not only the circular hole 22 and the small circular hole 23, but also holes of other shapes or notched holes.

Further, instead of the key shaft 8, the key hole 26 may be provided so as not to slide.

Furthermore, in the above embodiment, the key shaft 8 is provided on the side of the meter cable 4, and the key hole 26 is provided on the side of the main body 2, but the arrangement may be reversed as shown in FIG.

As described above, according to the present invention, the meter cable is fixed to the bracket in advance, and then the meter body is fixed from the front side of the instrument, and the ends of the meter cable are connected. The key shaft and key hole provided on the main body are reliably and naturally connected when the key shaft and key hole are aligned in the same direction by rotation of the key shaft, eliminating the troublesome connection between the meter main body and the meter cable as in the past. The present invention does not require attachment/detachment work, and can prevent problems such as needle runout due to poor connection between the meter cable and the meter body. In particular, according to the present invention, a bushing is provided between the outer casing and the joint inner. Since it has a diagonal groove for grease diffusion, the key shaft or key hole can rotate smoothly.

In addition, since the guide casing is provided with first and second flanges that are pressed against each other by spring force, the bracket is provided with a rising portion 10', and by simply providing a hole in this rising portion 10', the guide casing is That is, since the cable can be fixed, the structure is simple and operation is easy, and the cable can not only be firmly and firmly fixed to the bracket by the spring force, but also allow for errors in each part.
