Description

  The present invention relates to a mounting structure for a device operating cable such as a remote control load transmission cable used for, for example, a mechanism of an automobile seat.

  In a device operating cable (hereinafter simply referred to as an operating cable) in which an inner cable is inserted into an outer casing, when assembling the operating cable, mounting members at both ends, such as mounting brackets (fixing points of the outer casing) ) Due to manufacturing variations, the position of the outer casing end, which is the fixing point of the outer casing terminal, does not match the position of the mounting bracket, resulting in an error, and ignoring this will affect the operating performance of the operating cable. May affect. Therefore, conventionally, a structure for mounting an operating cable that absorbs the manufacturing variation of the mounting bracket has been proposed.

  FIG. 7 is a perspective view showing an example of the conventional example. The operating cable 1 is configured by inserting an inner cable 2 through an outer casing 4, and an end portion of the outer casing 4 is an outer casing end 4 a that is attached to a mounting bracket 9. The mounting bracket 9 is provided with a screw 11 by a bolt 11a and a nut 11b, and the operating cable 1 is attached to the screw 11. By adjusting the screw 11 to move back and forth, the outer casing end 4a and the mounting bracket 9 are connected to each other. It is configured to absorb mounting errors.

FIG. 8 is a perspective view showing another conventional example. In this conventional example, a plurality of ring-shaped concave grooves 12 are provided on the outer casing end 4a attached to the mounting bracket 9, and when mounting on the mounting bracket 9, mounting errors are caused by attaching to the mounting bracket 9 with the matching concave grooves 12. Absorbing configuration.
Further, the outer casing through which the inner cable is inserted is formed with concavities and convexities on the side surface in the axial direction, and a plate spring that is biased in the axial direction is integrally formed, and the bracket is inserted into the outer casing. A locking projection that clamps the groove and the lower edge of the end portion of the leaf spring is provided. When the outer casing is inserted into the insertion groove of the bracket, the end portion of the leaf spring is locked to the locking projection of the bracket and tensions the cable ( For example, see Patent Document 1).
Japanese Patent Laid-Open No. 10-274233

The conventional example shown in FIG. 7 requires adjustment with the bolts 11a and nuts 11b at the time of mounting, so a large work space is required, and some devices cannot be used, which may hinder miniaturization. There is a problem that the cost is significantly increased.
The conventional example shown in FIG. 8 does not require adjustment with bolts and nuts, so the work space can be narrowed.
Furthermore, when the outer casing is inserted into the insertion groove of the bracket, the device for tensioning the cable with the end of the leaf spring being locked by the locking protrusion of the bracket has a complicated structure of the outer casing and the bracket, and the manufacturing cost increases. There are problems and problems that cannot be used unless the outer casing and the bracket are paired.
The present invention has been proposed to solve such a problem, and its purpose is that the operating cable itself has a means for absorbing the mounting error, and the mounting bracket absorbs the mounting error even in a narrow work space. The object is to provide a device operating cable mounting structure that can be easily and accurately mounted.

  In order to achieve the above object, the device operating cable mounting structure of the present invention is a device operating cable mounting structure in which an inner cable is inserted into an outer tube, and the device operating cable is formed of an outer tube. The terminal portion is formed on an outer tube end to be attached to the attachment member, and the outer tube end is attached to the attachment member with an elastic body interposed between the outer tube end and the outer tube.

  With this configuration, the outer tube end of the operating cable is allowed to move in the axial direction within the elastic range due to the elasticity of the elastic body. Therefore, the outer tube end of the operating cable can absorb an attachment error with an attachment member (for example, an attachment bracket). Accordingly, the operating cable can be easily and accurately attached to the attachment member by absorbing the error with the attachment member by the elastic body and attaching the outer tube end.

In the device operating cable mounting structure according to the present invention, the inner peripheral surface of the elastic body is provided with a convex portion that abuts against the inner cable and inhibits movement.
With this configuration, the elastic body can be held at a predetermined position between the outer tube end and the outer tube, so that it moves between the outer tube end and the elastic body and between the elastic body and the outer tube. Can be prevented from being separated or separated. Therefore, the attachment is facilitated because it is held at a predetermined position.

Further, the device operating cable mounting structure of the present invention is characterized in that a spacer is interposed between the elastic body and the outer tube.
With this configuration, the contact surface between the elastic body and the outer tube has a high surface pressure, and biting occurs, so that it is possible to prevent bending from being absorbed by an appropriate elastic body, and it is possible to always properly absorb mounting errors.

Moreover, a rubber member, a resin member, or a spring can be mentioned as the elastic body of the present invention.
The shape of the rubber member and the resin member is not particularly limited as long as it has elasticity in the axial direction and can absorb the mounting error between the mounting member and the outer tube end. And select an appropriate shape. The spring is preferably a coil spring because it is inserted into the inner cable and causes elasticity in the axial direction.

Further, the device operating cable mounting structure of the present invention is a device operating cable mounting structure in which the inner cable is inserted through the outer tube,
The device operating cable is formed at the outer tube end where the end portion of the outer tube is attached to the attachment member, and the outer tube end is formed with a slit so that it can be expanded and contracted in the axial direction. Features.
Examples of the slit include those formed in a direction substantially orthogonal to the axis and those formed in a direction substantially parallel to the axis.

With this configuration, the outer tube end can be expanded and contracted in the axial direction by a slit. Therefore, even if an error occurs between the outer tube and a mounting member (for example, a mounting bracket), the outer tube end can be expanded and contracted. Can be absorbed. Therefore, the operating cable can be easily and appropriately attached to the attachment member by absorbing the error with the attachment member by the expansion and contraction of the outer tube end.
Here, the slit is substantially orthogonal to or substantially parallel to the axis, because the slit imparts stretchability to the outer tube end, so that the slit is perpendicular to or substantially parallel to the axis. The expansion and contraction is possible not only with the slits but also with the slits in the oblique direction.

According to the device operating cable mounting structure of the present invention, the following effects can be obtained.
(1) Since the outer tube end can be attached to the mounting member by absorbing an error with the mounting member (for example, a mounting bracket) with an elastic body, the operating cable can be easily and properly attached to the mounting member. it can. Moreover, it can be easily installed even in a narrow space.
(2) Since the elastic body can be held at a predetermined position between the outer tube end and the outer tube, the predetermined position is held at the time of mounting, and the mounting becomes easy.

(3) Even if the surface pressure of the contact surface between the elastic body and the outer tube is high, the spacer prevents biting, and an appropriate elastic body can appropriately absorb the error.
(4) Since the elastic body can be formed of a rubber member, a resin member, or a spring, it can be easily manufactured and can be provided at a low cost, and can be easily attached to the operating cable. In addition, the options used by the equipment will be expanded.
(5) The operating cable can be easily and appropriately attached to the mounting member by absorbing the error with the mounting member by expansion and contraction of the outer tube end. Therefore, it can be easily installed even in a narrow installation space.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a device operating cable attachment structure showing a first embodiment of the present invention. The same components as those in the conventional example are designated by the same reference numerals and will be described below.

  The operating cable mounting structure shown in FIG. 1 is an operating cable 1 mounting structure in which an inner cable 2 is inserted into an outer tube 4, and the operating cable 1 has an end portion of the outer tube 4, The outer tube end 4a is attached to a mounting bracket 9 as a mounting member, and the outer tube end 4a is attached to the mounting bracket 9 with an elastic body 5 interposed between the outer tube end 4a and the outer tube 4. ing. In this example, a locking member 3 is provided at the end of the inner cable 2 in order to facilitate connection with a device or the like.

  The elastic body 5 allows the outer tube end 4a to move in the axial direction by elasticity and absorbs an error from the mounting bracket 9, and is exemplified by a rubber member, a resin member (for example, urethane) or a coil spring. it can. In this example, the elastic body 5 is formed of a rubber member 5a. The rubber member 5a as the elastic body 5 of the present example has a solid cylindrical shape with an annular recess 6 provided in the middle, and shows a configuration that facilitates expansion and contraction (elasticity) in the axial direction.

  Therefore, according to the device operating cable mounting structure according to the first embodiment, the outer tube end 4a can move in the axial direction within the elastic range in the axial direction due to the elasticity of the rubber member 5a. Therefore, the outer tube end 4a can absorb the mounting error with the mounting bracket 9 by this movement. As a result, there is a manufacturing variation in the mounting bracket 9, and even if an installation error occurs between the outer cable end 4 a of the operating cable 1, the operating cable 1 absorbs the error by the outer tube end 4 a and the mounting bracket 9. Can be easily installed properly. Therefore, the operation cable 1 can always avoid installation that affects the operation.

FIG. 2 is a cross-sectional view of a device operating cable mounting structure showing a second embodiment of the present invention. In this example, a spacer 7 is interposed between the rubber member 5a as the elastic body 5 and the outer tube 4 in the first embodiment, and the others are the same as in the first embodiment. It is the same.
A surface pressure is generated on the contact surface between the rubber member 5a and the outer tube 4 by the elastic force of the rubber member 5a that is compressed and attached to the mounting bracket 9. When this surface pressure is high, biting occurs at the contact surface between the rubber member 5a and the outer tube 4, and the appropriate rubber member 5a may not absorb the deflection. In this second embodiment, a spacer 7 is interposed between the rubber member 5a and the outer tube 4 to suppress an increase in surface pressure, prevent biting, and proper installation and proper operation cable. Secure operation.
Therefore, according to the device operating cable mounting structure according to the second embodiment, the operating cable 1 prevents the biting due to the contact pressure between the rubber member 5a and the outer tube 4 and the rubber. Due to the elasticity of the member 5a, the outer tube end 4a can be easily attached to the mounting bracket 9 by absorbing the mounting error.
Examples of the spacer 7 include those made of resin and metal. As a preferred example, a disk shape having an outer diameter substantially equal to the outer diameter of the outer tube 4 can be shown.
In this example, the spacer 7 is interposed between the rubber member 5 a and the outer tube 4, but the rubber member 5 a can also be applied to other elastic bodies 5.

FIG. 3 is a perspective view of a device operating cable mounting structure showing a third embodiment of the present invention. The third embodiment is a case where a spring 5b is provided as an elastic body 5 in place of the rubber member 5a in the first embodiment, and the others are the same as in the first embodiment.
Even in the device operating cable mounting structure according to the third embodiment, the outer tube end 4a can move in the axial direction against the elastic force of the spring 5b. Due to this movement, it is possible to absorb the mounting error with the mounting bracket 9. Therefore, even if there is a mounting error between the mounting bracket 9 and the outer tube end 4 a, the operating cable 1 is connected to the outer tube end 4 a. The error can be absorbed and can be easily and appropriately attached to the mounting bracket 9.
The spring 5b may be made of metal or resin, but is preferably a coil spring that exhibits an elastic force in the axial direction, and a coil spring having an outer diameter substantially equal to the outer diameter of the outer tube 4 is the outer tube of the working cable 1. An outer diameter substantially equal to 4 is particularly preferable.

FIG. 4 is a perspective view of a device operating cable mounting structure showing a fourth embodiment of the present invention. In the fourth embodiment, the operating cable 1 is formed by inserting an inner cable 2 into an outer tube 4, and an outer tube end 4 a that is attached to a mounting bracket 9 at the end of the outer tube 4. A plurality of slits 10 in the direction orthogonal to the axial direction are formed in the tube end 4a, and the tube end 4a can mainly expand and contract in the axial direction. .
Accordingly, since the outer tube end 4a of the operating cable 1 can be expanded and contracted in the axial direction by the slit 10, the outer tube end 4a can absorb the mounting error with the mounting bracket 9 by the expansion and contraction. Thus, even if there is an attachment error between the attachment bracket 9 and the outer tube end 4a, the operating cable 1 can be easily attached to the attachment bracket 9 by absorbing the error in the outer tube end 4a.
In addition, although the slit formed in the outer tube end 4a is shown by the slit 10 orthogonal to the axis line in this example, the slit formed in the outer tube end 4a imparts elasticity to the outer tube end 4a. Therefore, not only the slit 10 orthogonal to the axis but also the slit parallel to the axis or the slit whose direction perpendicular to and parallel to the axis is oblique can be expanded and contracted. Therefore, the present invention includes not only slits orthogonal or parallel to the axial direction but also diagonal slits.

  FIG. 5 is a cross-sectional view of a device operating cable attachment structure showing a fifth embodiment of the present invention. In the operating cable 1 according to the fifth embodiment, an inner cable 2 is inserted into an outer tube 4, and a terminal portion of the outer tube 4 is formed at an outer tube end 4 a attached to a mounting bracket 9. A resin member 5 c is interposed as an elastic body 5 between the tube end 4 a and the outer tube 4. On the inner peripheral surface of the resin member 5c, a convex portion 8 that abuts on the inner cable 2 and suppresses the movement of the resin member 5c is provided. The movement of the convex portion 8 is restrained to such an extent that the position is maintained at the time of attachment but does not affect the operation of the cable 2. Others are the same as those in the first embodiment.

  In the operating cable 1 configured as shown in the first embodiment, since the outer tube end 4a and the elastic body 5 are merely inserted through the inner cable 2, the positions are predetermined as shown in FIG. It may be displaced from the position of. . If the outer tube end 4a and the elastic body 5 (resin member 5c) are misaligned as shown in FIG. 6, the position needs to be corrected when mounting to the mounting bracket 9, and the mounting (assembly) is complicated. become. However, in the working cable 1 according to the fifth embodiment, as shown in FIG. 5, the inner peripheral surface of the resin member 5 c as the elastic body 5 is brought into contact with the inner cable 2 and the resin member 5 c. Since the convex portion 8 that suppresses the movement is provided, the position of the resin member 5c is held at a predetermined position, and accordingly, the position of the outer tube end 4a is also held. It becomes easy.

Thus, according to the device operating cable mounting structure according to the fifth embodiment, the outer tube end 4a can move in the axial direction within the elastic range due to the elasticity of the resin member 5c. The outer tube end 4a can absorb the mounting error with the mounting bracket 9 by this movement. Therefore, even if there is a mounting error between the mounting bracket 9 and the outer tube end 4a, the operating cable 1 is The outer tube end 4a can be attached to the mounting bracket 9 easily by absorbing the mounting error. At the time of attachment, since the resin member 5c and the outer tube end 4a hold the predetermined positions, they can be easily attached without the need for correction of the positions.
In addition, although this example demonstrated the resin member 5c as the elastic body 5, this is applied also to another elastic body.
