Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cable terminal fixing device suitable for use as a control cable for remote control of a vehicle.
[0002]
[Prior art]
An example of a cable terminal fixing device for attaching a control cable for a vehicle is shown in FIG. In FIG. 7, a cylindrical socket member 52 through which an inner cable 51 is inserted is provided in a sleeve 50, and flange portions 53 and 54 are formed at the left end portion thereof. The flange portions 53 and 54 are fitted into the opening peripheral edge portion 56a of the opening portion 56 of the bracket member 55, and the corrugated washer 57 is driven between the bracket member 55 and the flange portion 53 while being elastically deformed by a dedicated tool such as a hammer. The socket member 52 is firmly elastically contacted with the bracket member 55. For this reason, it is expected that the elastic contact force of the corrugated washer 57 is reduced due to stress relaxation caused by a creep phenomenon at a high temperature with long-term use. If the elastic contact force of the corrugated washer 57 is reduced, the socket member 52 may rattle and cause vibration, or the socket member 52 may be easily detached from the bracket member 55, and a normal cable path may not be maintained.
In order to prevent this, fixing devices described in Japanese Patent Application Laid-Open No. 2000-240635 and European Patent Application Publication No. 0703395 have appeared. According to these publications, a torsion spring (elastic member) is used to urge the nut portion (movable member) to elastically contact the bracket member (wall portion), and the nut portion (movable member) is loosened. I am trying not to.
Japanese Patent Application Laid-Open No. 2002-122271 describes a one-touch cap for fixing a cable. The cap fixes the main body with a stopper and a socket sandwiching a fixing plate by a double nut method. At this time, the socket is urged in the tightening direction by the recoil spring, and the lock member is pushed into the stopper and engaged with the edge of the fixing plate to prevent the stopper from rotating.
[0003]
[Problems to be solved by the invention]
However, even if a torsion spring is used to prevent the nut portion from being loosened as in the above-described fixing device, the upward component force increases when a load in the diagonally upward direction is repeatedly applied to the cable or the like with long-term use. The socket member may come out of the opening and fall off. For convenience, when the bracket member 55 is bent or warped as shown by a two-dot chain line in FIG. 7, the socket member 52 can be easily removed from the opening 56 in the direction indicated by the arrow A1, and the arrows A2, A3 in FIG. When a load in the torsional direction is applied to the bracket member 55 as shown in FIG. 6, there is a risk that the nut portion will rotate in the loosening direction against the torsion spring and the socket member 52 may be easily removed.
In Japanese Patent Application Laid-Open No. 2002-122271, there is no possibility of rotating the socket in the loosening direction against the recoil spring due to rattling or vibration, because the socket is not provided with a detent means. Since the socket constitutes a single component separately from the main body, the number of components increases, which is disadvantageous in terms of cost. The resin stopper that receives the lock member so as to be slidable up and down has a complicated structure having a vertical slide groove therein. For this reason, there is a risk that the mold cost for stopper molding is increased and the productivity is lowered.
[0004]
The present invention has been made in the background of the above circumstances. The purpose of the present invention is to quickly fix the socket member to the bracket member by a relatively simple operation without using a washer or a tool. An object of the present invention is to provide a cable terminal fixing device that can reliably prevent a drop-off and maintain a strong fixing state of a socket member to a bracket member over a long period of time.

Operation and effect of the invention
(About claim 1)
In the cable terminal fixing device, when the socket member is fixed to the bracket member, the opening peripheral edge of the opening is sandwiched between the socket member and the cylindrical nut member, and the cylindrical nut member is released. At this time, an additional tightening torque is generated by the urging force of the urging member, and the cylindrical nut member is urged to rotate in the tightening direction along the male screw portion. For this reason, the looseness of the cylindrical nut member is removed, and the socket member and the cylindrical nut member are firmly elastically contacted with the opening peripheral edge of the opening.
Since the tightening torque of the urging member always works to remove the looseness of the cylindrical nut member, unlike the conventional case where a washer is used, the stress relaxation due to the creep phenomenon is eliminated and the looseness of the cylindrical nut member is surely eliminated. be able to. Since this can be realized by a single cylindrical nut member, the reduction in the number of parts is advantageous in terms of cost and excellent productivity.
[0012]
A stopper is provided that contacts the engaging portion formed on the cylindrical nut member and prevents the cylindrical nut member from rotating in the loosening direction to prevent rotation. For this reason, even when a diagonally upward load is applied to the cable or the like as an external force, the cylindrical nut member does not rotate unintentionally against the biasing force of the biasing member, and the cylindrical nut member is loosened. There is no.
Even if the bracket member is bent or warped or a load in the twisting direction is applied as an external force, the stopper prevents the cylindrical nut member from rotating in the loosening direction. Since the stopper works as a stopper for the cylindrical nut member, there is no possibility that the socket member is prevented from coming off and coming out of the opening. As a result, even if the cable or the like repeatedly receives external force, the cylindrical nut member is always urged to rotate in the tightening direction without loosening. Thereby, in order to hold | maintain a regular cable path | route, the solid fixing state of the socket member with respect to a bracket member can be maintained over a long period of time.
Since the cylindrical nut member is prevented from rotating in the loosening direction, and this loosening prevention works as a retaining member for the socket member, a strong fixed state of the socket member can be ensured. As a result, the fixing of the socket member can be effectively handled even when the thickness of the bracket member is relatively large.
In addition, when fixing the socket member, the cylindrical nut member is rotated once in the loosening direction and then released, and it can be quickly and easily operated by simply operating the stopper. To do.
[0013]
(Claim 2)
When attaching the socket member to the bracket member, first, the cylindrical nut member is rotated relative to the socket member in the loosening direction against the urging force of the urging member. After the cylindrical nut member is temporarily secured by the stopper, the cylindrical nut member is released by sandwiching the opening periphery of the opening between the socket member and the cylindrical nut member. Thereby, the cylindrical nut member is rotated in the tightening direction around the male screw portion by the urging force of the urging member, and the cylindrical nut member is prevented from rotating in the loosening direction (loosening prevention) by operating the stopper.
For this reason, fixing the socket member to the bracket member can be quickly performed by a simple operation of simply rotating the cylindrical nut member in the loosening direction and then releasing it to operate the stopper. As a result, the productivity is greatly improved due to good work efficiency without requiring special special tools.

  In the stopper, the socket memberOn the guide wall provided between the formed flangesRemovably providedThe socket member against the bracket openingSecure the insertion gapdo itTemporary stop position that restricts the screw displacement of the cylindrical nut member, temporary stop release position that releases the stopper when the socket member is inserted into the opening and releases the screw member displacement of the cylindrical nut member, and pressing of the stopper By the operation, it is possible to displace between the locking position for preventing the cylindrical nut member from rotating in the loosening direction. Accordingly, there is an advantage that a series of operations such as temporary release from the cylindrical nut member and release and lock can be quickly performed by a simple operation of simply displacing the stopper to each position.
  In addition, since the stopper is detachably attached to the socket member, by attaching the stopper to the socket member, the stopper is integrated with the socket member, so that the stopper is not lost and the series of operations of the stopper is smooth. Can be done.

  The stopper has a lower leg and an upper abutment.WithWhen the socket member is attached to the opening of the bracket member, the stopper is pressed by a pressing operation.LegsIt is mounted at the lock position so as to straddle the socket member, and the abutting portion comes into contact with the engaging portion of the cylindrical nut member to prevent the cylindrical nut member from rotating in the loosening direction. Still, stopperIs the oppositeA simple structure formed in a U shape is sufficient, and the entire structure is not complicated, which is advantageous in terms of cost.
[0016]
(Claim 5)
A narrow portion that allows the open end of the opening of the bracket member to pass through and a wide portion that restricts the passage of the open end are formed on the outer surface of the step portion of the socket member. For this reason, by inserting the bracket member from the narrow part into the open end of the opening and fitting the wide part into the opening, the wide part serves as a retainer for the open end so that the socket member can be pulled out of the opening. Absent. Also from this viewpoint, it is possible to prevent the socket member from falling off and maintain a favorable fixed state of the socket member with respect to the bracket member over a long period of time.
[0017]
(About claim 6)
The cable is used as a control cable for remote control of the vehicle. The socket member is firmly fixed to the bracket member in a retaining state while securing the looseness of the cylindrical nut member. Even when the socket member receives a relatively large external force, the socket member is maintained firmly fixed to the bracket member without falling off the bracket member. Therefore, the cable terminal fixing device is suitable for application to a control cable for a vehicle that easily receives external forces such as vibration and rattling during traveling.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
In the first embodiment of the present invention, the cable terminal fixing device 1 shown in FIG. 1 is formed of an appropriate material such as metal or plastic, and has a stepped cylindrical socket in which small-diameter pipe portions 2 are integrally connected. A member 3 and a cylindrical nut member 4 are provided. A predetermined number of male threaded portions 2a are formed on the outer peripheral portion of the tube portion 2 of the socket member 3, and the cylindrical nut member 4 is attached so as to be able to advance and retract.
The torsion coil spring 5 as an urging member is disposed in the cylindrical nut member 4 in a state in which the male screw portion 2a is loosely fitted. The open end of the tube portion 2 forms a notch 6, and the open end of the cylindrical nut member 4 forms a notch 7. One end portion 5 a of the torsion coil spring 5 is detachably engaged with the notch portion 6 of the tube portion 2, and the other end portion 5 b of the torsion coil spring 5 is detachably fitted into the notch portion 7 of the cylindrical nut member 4. . Due to the urging force of the torsion coil spring 5, the cylindrical nut member 4 is always urged to rotate in the tightening direction along the male screw portion 2a as indicated by an arrow B.
[0019]
The cable in the cable terminal fixing device 1 is applied to, for example, a control cable 8 for remote operation to link a vehicle shift lever to a transmission (not shown). The control cable 8 is attached to the socket member 3 and the cylindrical nut member 4 in an inserted state via a sleeve 9 provided with an inner cable 10 at the core. The control cable 8 is fixed to the plate-like bracket member 20 by the cable terminal fixing device 1 as will be described later. The bracket member 20 is formed in a substantially reverse keyhole shape from a circular opening 21 and a narrow open end 22 located at the upper end.
[0020]
A front flange 12 and a rear flange 13 are formed in a concentric state on the step portion 11 which is a boundary portion between the socket member 3 and the pipe portion 2, leaving a slight interval T1 in the front-rear direction. Between the front and rear flanges 12 and 13, linear guide wall portions 14 are provided on both the left and right sides, and an engaging protrusion 15 is formed at the center of the guide wall portion 14. The front flange 12 is formed with left and right corner portions 16 having substantially the same dimensions as the distance between the left and right guide wall portions 14, and a flat fitting surface 17 is provided between the corner portions 16 and 16. An arcuate wide portion 18 is formed integrally with the front flange 12 on the outer surface portions of the left and right corner portions 16. A straight vertical wall portion immediately adjacent to the wide portion 18 of the outer surface portions of the left and right corner portions 16 is defined as a narrow portion 19. The spacing dimension H of the narrow portion 19 is set slightly smaller than the width dimension P of the open end 22 of the bracket member 20, and the spacing dimension of the wide portions 18, 18 is M and the width dimension P of the open end 22. It is large and set to be approximately equal to the diameter D of the opening 21.
[0021]
  SeoKet member3A stopper 23 is detachably provided on the guide wall 14. The stopper 23 is an elastic member such as metal or plastic.ReverseIt is formed in a U shape, has a long leg portion 24 straddling the guide wall portion 14 at the lower end, and a contact portion 25 corresponding to the left and right corner portions 16 at the upper end. The contact portion 25 is inserted into the corner portion 16 and the fitting surface 17 to form a block-like fitting portion 26 that prohibits the horizontal displacement of the stopper 23. On the outer surface of the fitting portion 26, a stepped lock portion 27 protruding left and right is formed. An arcuate slidable contact surface 25a corresponding to the small-diameter outer peripheral cylindrical portion 4A of the cylindrical nut member 4 is formed on the lower surface portion of the fitting portion 26 where the lock portion 27 is located.
[0022]
An upper claw 29 and a lower claw 30 are formed inside the leg portion 24 of the stopper 23 at intervals corresponding to the thickness of the engagement protrusion 15. The upper part of the upper claw 29 is a sliding side part 31, and the recess between the upper claw 29 and the lower claw 30 is a valley part 32. Prior to the mounting of the socket member 3, the stopper 23 is inserted so as to straddle the guide wall portions 14 and 14 of the socket member 3 via the leg portion 24 as shown in FIG. 31 is brought into elastic contact with the engaging protrusion 15. That is, the state of (a) in FIG. 2 is the stopper 23 when the socket member 3 is inserted into the opening 21 of the bracket member 20 when the cylindrical nut member 4 is assembled to the socket member 3 together with the torsion coil spring 5. The temporary fixing position is shown. After the insertion, the stopper 23 is pulled up to the temporary stop release position where the valley 32 is engaged with the engaging protrusion 15 as shown in FIG. Further, the stopper 23 is moved downward to a locked position where the upper claw 29 is engaged with the engaging protrusion 15 as shown in FIG.
2 (c), the lock portion 27 on the right side is engaged with the engaging portion 28 of the protrusion formed on the outer peripheral portion of the cylindrical nut member 4 at the opening end 4a opposite to the notch portion 7. Engage. For this reason, the cylindrical nut member 4 is prevented from rotating in the loosening direction opposite to the arrow B against the urging force of the torsion coil spring 5.
[0023]
In the above configuration, the following installation preparations are made prior to fixing the control cable 8 to the bracket member 20 by the cable terminal fixing device 1. That is, the stopper 23 is slightly pulled up to the temporarily fixed release position in which the engaging protrusion 15 is elastically engaged with the valley 32 as shown in (b) of FIG. Deploy. In this state, the cylindrical nut member 4 is attached to the male screw portion 2a and tightened until the open end 4a of the outer peripheral cylindrical portion 4A comes into contact with the front wall portion 16a of the corner portion 16.
[0024]
Thereafter, the one end portion 5a of the torsion coil spring 5 is fitted into the notch portion 6 of the pipe portion 2, and the torsion coil spring 5 is wound and contracted by a predetermined angle in the accumulating direction while holding the cylindrical nut member 4 in a contact state. (For example, 1/8 to 1/2 rotation), the other end 5 b is fitted into the cut portion 7 of the cylindrical nut member 4. When the cylindrical nut member 4 is released, a tightening force is applied to the cylindrical nut member 4 by the biasing force of the torsion coil spring 5 to generate a set amount of tightening torque.
[0025]
When the preparation for installation is completed, as shown in FIGS. 3 and 4, the cylindrical nut member 4 is twisted and rotated in the loosening direction against the urging force of the coil spring 5, and the stopper 23 is moved in FIG. Is pushed to the temporary fixing position, and the front end portion 27F of the stopper is brought into contact with the opening end 4a of the cylindrical nut member 4 to restrict the screw displacement of the cylindrical nut member 4. Thereby, the insertion gap in consideration of the thickness t of the bracket member 20 is ensured between the opening end 4a and the front flange 12.
At this temporary fixing position, the rotation of the cylindrical nut member 4 due to the urging force of the torsion coil spring 5 is temporarily prevented. Next, the socket member 3 is inserted into the insertion gap from the narrow portion 19 through the open end portion 22 of the bracket member 20, and the narrow portion 19 is moved downward along the open end portion 22. Furthermore, the movement is continued, and the lower end portion of the front surface portion 27F of the stopper 23 is caused to interfere with contact with the upper surface portion 20X of the bracket member 20. As a result, the stopper 23 is displaced upward, and as shown in FIG. 2B, the stopper 23 is moved up to the temporary stop releasing position where the restriction of the screwing displacement of the cylindrical nut member 4 is released.
[0026]
At the temporary fastening release position, the screwed displacement of the cylindrical nut member 4 is released, so that the cylindrical nut member 4 rotates in the tightening direction indicated by the arrow B along the male screw portion 2a by the biasing force of the torsion coil spring 5. Be energized. For this reason, the opening end 4a of the cylindrical nut member 4 is elastically contacted with the front flange 12 and the opening peripheral edge 21a of the opening 21 with a set amount of tightening torque. In this case, the distance M between the wide portions 18 is substantially equal to the diameter D of the opening 21 and larger than the width P of the open end 22, so that the wide portion 18 contacts the lower end of the open end 22. Thus, it functions as a stopper for restricting the passage of the socket member 3.
[0027]
In this state, when the contact portion 25 of the stopper 23 is pressed, the stopper 23 is displaced from the temporarily fixed release position shown in FIG. 2B to the lock position shown in FIG. The sliding surface 25a is inserted into the mating surface 17 and comes into contact with the outer cylindrical portion 4A. Along with this, the upper claw 29 of the leg portion 24 gets over the engagement protrusion 15 by elastic deformation and engages with the engagement protrusion 15. At this time, since the right lock portion 27 engages with the engagement portion 28, the cylindrical nut member 4 is prevented from rotating in the loosening direction (loosening prevention). For this reason, the cylindrical nut member 4 does not rotate in the loosening direction opposite to the arrow B against the urging force of the torsion coil spring 5. Further, since the rotation of the cylindrical nut member 4 is braked by the contact of the sliding contact surface 25a with the outer peripheral cylindrical portion 4A, this also contributes to the prevention of the loosening of the cylindrical nut member 4.
[0028]
In order to remove the socket member 3 from the bracket member 20 at the time of repair, repair or repair, the stopper 23 is pulled up from the locked position (C) in FIG. Then, the cylindrical nut member 4 is loosened against the urging force of the torsion coil spring 5 to secure an insertion gap, the wide portion 18 is removed from the opening portion 21, and the narrow portion 19 is pulled out from the open end portion 22. That's fine.
In this case, instead of loosening the cylindrical nut member 4 against the urging force of the torsion coil spring 5, the other end 5 b of the torsion coil spring 5 is forcibly removed from the cut portion 7 of the cylindrical nut member 4. After releasing the urging force in the tightening direction of the torsion coil spring 5, the socket member 3 may be pulled out from the open end 22.
[0029]
In the above configuration, when the socket member 3 is attached to the bracket member 20, an additional tightening torque is generated by the urging force of the torsion coil spring 5, and the cylindrical nut member 4 is urged to rotate in the tightening direction along the male screw portion 2a. Let For this reason, the looseness of the cylindrical nut member 4 is removed, and the socket member 3 and the cylindrical nut member 4 are firmly elastically contacted with the opening peripheral edge portion 21a of the opening portion 21. Since the tightening torque of the torsion coil spring 5 always works to remove the looseness of the cylindrical nut member 4, unlike the conventional case using a washer, stress relaxation caused by a creep phenomenon is eliminated and the tubular nut member 4 is loosened. It can be definitely eliminated.
[0030]
A stopper 23 is provided on the socket member 3, and the lock portion 27 is brought into contact with the engaging portion 28 to act as a detent in the loosening direction of the cylindrical nut member 4. Therefore, even when a diagonally upward load is applied to the control cable 8 or the like as an external force, the cylindrical nut member 4 does not rotate carelessly against the biasing force of the torsion coil spring 5, and the cylindrical nut member 4 Will not loosen.
Even if the bracket member 20 is bent or warped or a load in the twisting direction is applied as an external force, the stopper 23 prevents the cylindrical nut member 4 from rotating in the loosening direction. For this reason, the stopper 23 works as a loosening prevention of the cylindrical nut member 4, and the cylindrical nut member 4 does not rotate in the loosening direction. As a result, the axial displacement of the socket member 3 is prevented, the wide portion 18 is not detached from the opening 21, the socket member 3 is prevented from coming off from the open end 22, and the socket member 3 may come out of the opening 21. Absent.
[0031]
For this reason, even if the control cable 8 or the like repeatedly receives external force, the cylindrical nut member 4 is always urged to rotate in the tightening direction without being loosened. As a result, the socket member 3 can be firmly fixed to the bracket member 20 for a long period of time in order to maintain a normal cable path.
Since the cylindrical nut member 4 is prevented from rotating in the loosening direction, and this loosening prevention works as a retaining member for the socket member 3, the socket member 3 can be firmly fixed, and the thickness of the bracket member 20 is relatively large. It can be effectively applied to cases.
In particular, in this embodiment, when the stopper 23 is disposed at the temporary fixing release position shown in FIG. 2B, the leg portion 24 snaps and the engagement protrusion 15 is elastically engaged with the trough portion 32. For this reason, a feeling of moderation is generated by the release reaction force generated from the snap displacement, and an engagement sound is generated as a release sound, and an advantage that it is easy to perceive the completion of the arrangement of the stopper 23 is obtained.
[0032]
FIG. 6 shows a second embodiment of the present invention. In the second embodiment, semicircular small hole portions 33 are formed at positions facing the left and right of the open end portion 22. The socket member 3 is provided with a semicircular ear portion 34 corresponding to the small hole portion 33 in place of the wide portion 18 of the first embodiment. When the socket member 3 is attached to the bracket member 20, the ear portion 34 is fitted into the small hole portion 33 and is prevented from being detached from the open end portion 22 of the opening portion 21.
Even if comprised in this way, the effect similar to 1st Example is acquired. In the second embodiment, the same members as those in the first embodiment are denoted by the same reference numerals and only different portions are described.
[0033]
(Modification)
(A) The cross-sectional shape of the socket member 3 and the cylindrical nut member 4 is not limited to a circle, and may be arbitrarily changed as necessary, such as an ellipse, a rhombus, a triangle, a bowl, and a polygon.
(B) The urging member is not limited to the torsion coil spring 5, but may be an elastic member such as rubber, a clip, a snap ring, or the like, as long as the urging member rotates and urges the cylindrical nut member 4 in the tightening direction. Good.
(C) The urging force of the torsion coil spring 5 can be adjusted as desired by changing the amount of winding or shrinking according to the use situation or the object of use, or by changing the number of turns or the wire diameter of the strands.
(D) The cable terminal fixing device 1 can be used to remotely open and close a vehicle trunk, bonnet, hood, air conditioning louver, window, lid or ventilation fan as well as the control cable 8 for remote control of the transmission. Widely applicable to what you do.
