Description

[Technical field]

[0001] The present invention relates to a control cable and a casing cap. [Background technology]

[0002] There is known a control cable that includes an inner cable that outputs a load to an object to be operated, an outer casing into which the inner cable is inserted, and a casing cap that fixes an end of the outer casing and advances the inner cable to the outside. For example, Patent Document 1 discloses a technique in which a reinforcing tube (3) is fitted into the inner surface of a cylindrical outer casing (6) and a cap (4) is fitted onto the tip of the outer casing (6). The disclosed configuration includes fitting a bushing (5) between the cap (4) and the reinforcing tube (3), fitting a first protruding shaft (7) of the bushing (5) into the inner surface of the reinforcing tube (3), and inserting an inner cable (2) into a through hole (50) and the inner surface of the reinforcing tube (3) with a second protruding shaft (70) passing through the cap (4).

[0003] According to the configuration of Patent Document 1, the inner cable (2) is inserted through the through hole (50) of the bushing (5) and the inner surface of the reinforcing tube (3). Therefore, the inner cable (2) comes into contact with and slides against the tip edge of the reinforcing tube (3) and the through portion of the cap (4), so there is no risk of the inner cable (2) being worn or cut.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 7-38741 (particularly, paragraphs 0005-0007, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0005] However, because the cable is routed in a curved manner to the object to be operated, an operating load from the inner cable (2) acts on the outer casing (6). This causes a load to act on the cap (4) in a direction perpendicular to the axial direction of the cap (4). As a result, the hole shape of the second protruding shaft (70) is deformed and enlarged, causing a gap between the inner cable (2) and the second protruding shaft (70). Water may enter the outer casing (6) through this gap. From this perspective, it is desirable to improve the waterproof function of the casing cap.

[0006] An object of the present invention is to provide a control cable and a casing cap that can improve waterproofing performance compared to conventional control cables and casing caps. [Means for solving the problem]

[0007] A control cable according to one aspect of the present invention is a control cable including a casing cap that is fixed to an outer casing having an inner cable inserted therein and that outputs a load to an object to be operated, the inner cable having a through hole formed from one end to the other end and having a linear axis, The casing cap includes: a casing fixing portion that accommodates and fixes the outer casing in the through hole on the one end side; an inner seal portion that causes an inner cable, which is inserted inside the outer casing, to advance to the outside from the through hole on the other end side, The inner seal portion is a seal member disposed on the one end side, the seal member having an insertion hole through which the inner cable is inserted, the seal member having an inner peripheral surface on which a lip portion that abuts against an outer peripheral surface of the inner cable is formed, and and a washer member that is disposed closer to the other end than the seal member and that suppresses deviation of the inner cable in a perpendicular direction relative to the axis of the inner cable. Effect of the Invention

[0008] According to the present invention, it is possible to provide a control cable and a casing cap that can improve waterproofing performance more than before. [Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is an explanatory diagram of a control cable equipped with a casing cap. [Diagram 2] FIG. 4 is a cross-sectional view of the casing cap. [Diagram 3] FIG. 4 is an enlarged cross-sectional view showing a portion of the casing cap. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] (Control cable 1) As shown in FIG. 1, the control cable 1 includes an inner cable 32 that outputs a load to an operation target 6, an outer casing 31 into which the inner cable 32 is inserted, and a casing cap 2 that fixes an end of the outer casing 31 and advances the inner cable 32 to the outside. Here, an example of the operation target 6 is an application that is attached to the outside of a vehicle body, such as a parking brake of an automobile. This makes the control cable 1 applicable to a drive device that operates a parking brake, etc. Note that the control cable 1 may be applied to a general automobile, a drive device of a bicycle, a drive device of a construction machine such as a crane or a forklift, a drive device of an agricultural machine such as a tractor or a combine, or a drive device of various other industrial devices.

[0012] The inner cable 32 has a core member formed by bundling a large number of wires or fibers, and a covering layer that protects the core member. The core member has high strength due to the wires and fibers being woven together. The core member is made of materials such as steel wire, alloy, and fiber. On the other hand, the covering layer is made of plastic materials such as polyvinyl chloride (PVC), polyurethane, and nylon, and protects the core member by providing functions such as insulation, abrasion resistance, and chemical resistance.

[0013] The outer casing 31 is formed to protect and support the inner cable 32 from the external environment. Specifically, the outer casing 31 has a tubular structure that surrounds the inner cable 32 and protects the inner cable 32 from the outside. The outer casing 31 also has a guiding function for maintaining the appropriate position and direction of the inner cable 32. The outer casing 31 is made of metal (steel, aluminum, etc.), plastic (polyvinyl chloride (PVC), polyethylene, polyurethane, etc.), rubber, etc.

[0014] The casing cap 2 is configured to fix an end of the outer casing 31 and allow the inner cable 32 to advance to the outside. A specific example is as follows.

[0015] (Casing cap 2) 2, the casing cap 2 has a through hole 24, for example, annular (circular or elliptical) having a linear axis O, formed from one end to the other end. The hole shape of the through hole 24 is not limited to annular and may be polygonal. An outer casing 31 and an inner cable 32 are inserted through the through hole 24. Specifically, the casing cap 2 is configured such that the outer casing 31 is inserted from one end side, and after the inner cable 32 is exposed from the outer casing 31 inside the casing cap 2, only the inner cable 32 advances to the other end side.

[0016] The casing cap 2 has a casing fixing portion 23 formed in a region on one end side, an inner seal portion 21 formed in a region on the other end side, and an inner insertion portion 22 formed in a region between the casing fixing portion 23 and the inner seal portion 21. The casing fixing portion 23 has a casing through hole 231 as a through hole 24. The casing through hole 231 has a hole diameter larger than the outside diameter of the outer casing 31, and is capable of housing the outer casing 31.

[0017] The inner insertion portion 22 has an inner insertion hole 221 as a through hole 24. The inner insertion hole 221 has a hole diameter larger than the outer diameter of the inner cable 32 and smaller than the hole diameter of the casing through hole 231. The difference in hole diameter between the casing through hole 231 and the inner insertion hole 221 creates a step between the casing through hole 231 (casing fixing portion 23) and the inner insertion hole 221 (inner insertion portion 22). As a result, the casing fixing portion 23 has a first abutment surface 232 at the boundary surface with the inner insertion portion 22 that is perpendicular to the axis O and faces one end side. The first abutment surface 232, when viewed from the direction of the axis O, is formed in a ring shape with a hole diameter larger than the outer diameter of the inner cable 32 and smaller than the hole diameter of the casing through hole 231, so that it abuts only against the end face 311 of the outer casing 31, making it possible to fix the outer casing 31 to the other end side in the direction of the axis O.

[0018] The inner seal portion 21 has a first seal through hole 211 and a second seal through hole 212 as through holes 24. The first seal through hole 211 and the second seal through hole 212 are formed in the other end side region and the one end side region of the inner seal portion 21, respectively. The first seal through hole 211 has a larger hole diameter than the second seal through hole 212. The difference in hole diameter between the first seal through hole 211 and the second seal through hole 212 causes a step between the first seal through hole 211 and the second seal through hole 212. As a result, the inner seal portion 21 has a second abutment surface 213 that is perpendicular to the axis O and faces the other end side at the boundary surface between the first seal through hole 211 and the second seal through hole 212. The second abutment surface 213 makes it possible to fix the seal member 4 to the one end side in the axis O direction. Details will be described later.

[0019] The second seal through hole 212 has a larger hole diameter than the inner insertion hole 221. The difference in hole diameter between the second seal through hole 212 and the inner insertion hole 221 causes a step between the second seal through hole 212 (inner seal portion 21) and the inner insertion hole 221 (inner insertion portion 22). As a result, the inner seal portion 21 has a third abutment surface 214 at the boundary surface between the second seal through hole 212 and the inner insertion hole 221 that is perpendicular to the axis O and faces the other end side.

[0020] The casing cap 2 has an insertion opening 233 on one end side of the casing fixing part 23 that has a larger diameter than the hole diameter of the casing through hole 231 and is gradually reduced in size from the one end side to the other end side of the casing through hole 231. This allows the insertion opening 233 to easily insert the outer casing 31 into the casing through hole 231.

[0021] In addition, a protrusion 222, a first groove 223, and a second groove 224 are formed on the outer peripheral surface of the inner insertion portion 22. The protrusion 222 constitutes a part of an annular convex portion 225 formed in the circumferential direction on the outer peripheral surface of the inner insertion portion 22, and is formed in a rectangular shape with the axis O direction as the longitudinal direction. This makes it possible to visually identify the circumferential position of the casing cap 2, for example, by using the protrusion 222 as a mark. In addition, the first groove 223 and the second groove 224 are formed in an annular shape in the circumferential direction on the outer peripheral surface of the inner insertion portion 22, and each of them can be fitted with an O-ring (not shown). In addition, a fixing portion 215 protruding inward is formed at the end on the other end side of the inner seal portion 21. The fixing portion 215 abuts against the end face on the other end side of the washer member 5 to prevent the washer member 5 from falling off the casing cap 2.

[0022] (Washer part 5) 3, the casing cap 2 configured as described above has a seal member 4 and a washer member 5 in the inner seal portion 21. The seal member 4 and the washer member 5 are provided in the through hole 24 consisting of the first seal through hole 211 and the second seal through hole 212. The seal member 4 and the washer member 5 have a first insertion hole 44 and a second insertion hole 53, respectively. The axial centers of the first insertion hole 44 and the second insertion hole 53 are aligned with the axial center O of the through hole 24.

[0023] The washer member 5 is disposed closer to the other end side than the seal member 4, and suppresses the deviation of the inner cable 32 in the vertical direction with respect to the axis O. Specifically, the washer member 5 is accommodated in the first seal through hole 211. The washer member 5 has a deviation suppression portion 52 and a washer side overlap portion 51 at one end side and the other end side. The deviation suppression portion 52 has a deviation suppression hole 522 as a part of the second insertion hole 53. The deviation suppression hole 522 is set to a hole diameter smaller than the inner insertion hole 221 (through hole 24) in the inner insertion portion 22. As a result, the washer member 5 suppresses deviation of the inner cable 32, and prevents a gap from being generated between the seal member 4 and the inner cable 32 even when the inner cable 32 receives a large amount of load associated with the bending of the inner cable 32. As a result, the washer member 5 can improve the waterproof function of the casing cap 2 as a whole, including the inner insertion portion 22.

[0024] The inner circumferential surface of the bias suppression hole 522 is formed in a curved convex shape so that the center in the direction of the axis O is the apex. As a result, when the inner cable 32 is curved, the bias suppression hole 522 comes into planar contact with the inner cable 32, making it possible for the washer member 5 to distribute the load associated with the bending of the inner cable 32. Furthermore, since the washer member 5 suppresses deformation and wear of the bias suppression hole 522, it is possible to enhance the waterproof function of the entire casing cap 2 including the inner insertion portion 22 for a long period of time. In addition, a ring-shaped groove portion 521 is formed in the outer circumferential surface of the bias suppression portion 52.

[0025] The washer member 5 has a seal member accommodating hole 511 as a second insertion hole 53 in the washer side overlapping portion 51. The seal member accommodating hole 511 has a hole diameter and depth that allows the first seal portion 41 of the seal member 4 to be loosely fitted therein.

[0026] (Sealing material 4) The seal member 4 is disposed on one end side of the inner seal portion 21. The seal member 4 has a first seal portion 41 and a second seal portion 43 on the other end side and one end side, and has a flange portion 42 between the first seal portion 41 and the second seal portion 43. The first seal portion 41 is loosely fitted in the seal member accommodating hole 511 of the washer member 5. That is, the first seal portion 41 is in a non-contact state with the washer member 5. As a result, the washer member 5 and the seal member 4 overlap in a part (the first seal portion 41 and the washer side overlap portion 51) in a direction perpendicular to the axis O, and a gap is formed between the washer member 5 and the seal member 4 at the overlapping portion. As a result, even if the first seal portion 41 moves in a direction perpendicular to the axis O with the bending of the inner cable 32 and stress from the inner cable 32 acts on the seal member 4, the first seal portion 41 moves through the gap at the overlapping portion to reduce the stress. This enables the washer member 5 and the seal member 4 to have an even greater waterproof function.

[0027] The flange portion 42 of the seal member 4 has an outer diameter equal to that of the washer member 5, and is housed in the first seal through hole 211. An end face on one end side of the flange portion 42 abuts against the second abutment surface 213. On the other hand, an end face on the other end side of the flange portion 42 abuts against an end face of the washer side overlapping portion 51 of the washer member 5. As a result, the flange portion 42 fixes the seal member 4 in the axial direction O, and is pressed against the second abutment surface 213 by the washer member 5. As a result, the seal member 4 achieves high watertightness by the flange portion 42 being in close contact with the second abutment surface 213. Note that it is preferable that the angle of the boundary between the second seal through hole 212 and the first seal through hole 211 that form the second abutment surface 213 has a small radius of curvature. That is, it is preferable that the angle of the boundary between the second seal through hole 212 and the first seal through hole 211 has a radius of curvature smaller than the radius of curvature of at least other portions. This is because the area of ​​the second abutment surface 213 perpendicular to the axis O is increased, thereby increasing the abutment area between the flange portion 42 and the second abutment surface 213, thereby ensuring high sealing performance. For example, when the outer diameter of the flange portion 42 is 9.9 mm and the outer diameter of the second seal portion 43 is 7.0 mm, it is preferable that the radius of curvature is 0.2 mm to 0.5 mm.

[0028] The outer circumferential surface of the second seal portion 43 has outer circumferential lip portions 432, 432 formed at two locations in the axial center O direction. The outer circumferential lip portions 432, 432 may be formed at one location in the axial center O direction, or at two or more locations in the axial center O direction. The outer circumferential lip portions 432, 432 have a wedge-shaped cross-sectional shape and are formed in an annular shape in the circumferential direction of the second seal portion 43. The outer diameter of the outer circumferential lip portions 432, 432 is set to be larger than the hole diameter of the second seal through hole 212 of the casing cap 2. As a result, the outer circumferential lip portions 432, 432 are tightly and firmly in contact with the inner circumferential surface of the second seal through hole 212, thereby fixing the seal member 4 to the casing cap 2 and blocking water that enters through a gap between the seal member 4 and the casing cap 2 at the contact portion. In addition, the end face on one end side of the second seal portion 43 is separated from the third abutment surface 214 of the casing cap 2. As a result, the seal member 4 is able to absorb dimensional errors during manufacturing by providing a gap between the end face on one end side of the second seal portion 43 and the third abutment surface 214 of the casing cap 2.

[0029] The first seal portion 41, the flange portion 42, and the second seal portion 43 have a first insertion hole 44. The axis of the first insertion hole 44 is aligned with the axis O of the through hole 24. The inner diameter of the first insertion hole 44 in the first seal portion 41 is smaller than the inner diameter of the first seal portion 41 in the second seal portion 43. The first insertion hole 44 in the flange portion 42 has an inner diameter that differs at the center in the axis O direction, with the other end side aligned with the inner diameter of the first insertion hole 44 of the first seal portion 41 and the one end side aligned with the inner diameter of the first insertion hole 44 of the second seal portion 43.

[0030] In the first insertion hole 44 of the first seal portion 41, first protrusions 413, 413 protruding radially inward are formed at two locations in the direction of the axis O. The first protrusions 413, 413 are formed as lip portions in an annular shape in the circumferential direction of the inner wall surface. The first protrusions 413, 413 are formed in a corrugated cross section, and the inner diameter of the top is set to a diameter smaller than the outer diameter of the inner cable 32. In addition, in the first insertion hole 44 of the second seal portion 43, second protrusions 431, 431 protruding radially inward are formed as lip portions in an annular shape in the circumferential direction of the inner wall surface. The second protrusions 431, 431 are formed in a corrugated cross section, similar to the first protrusions 413, 413, and the inner diameter of the top is set to a diameter smaller than the outer diameter of the inner cable 32. As a result, the first protrusions 413, 413 and the second protrusions 431, 431 abut against the outer peripheral surface of the inner cable 32, making it possible to block water that enters through the gap between the sealing member 4 and the inner cable 32 at the abutment point.

[0031] Additionally, the inner diameter L2 of the second protruding portions 431, 431 is set to be smaller than the inner diameter L1 of the bias suppression hole 522 (second insertion hole 53) of the washer member 5 and larger than the inner diameter L3 of the first protruding portion 413. As a result, the seal member 4 can ensure sealing performance by the second seal portion 43 and can ensure the tracking ability of the inner cable 32 by the first seal portion 41, thereby ensuring sealing performance and slidability.

[0032] (summary) The control cable 1 according to one embodiment of the present invention has been described above. The control cable 1 of the above-described embodiment mainly includes the following configuration.

[0033] (1) A control cable 1 is provided with a casing cap 2 fixed to an outer casing 31 in which a through hole 24 having a linear axis O is formed from one end to the other end, and an inner cable 32 that outputs a load to an operation target 6 is inserted, The casing cap 2 is a casing fixing portion 23 that accommodates and fixes the outer casing 31 in the through hole 24 on one end side; an inner seal portion 21 that causes the inner cable 32 inserted inside the outer casing 31 to advance to the outside from a through hole 24 on the other end side, The inner seal portion 21 is a seal member 4 disposed on one end side, having lip portions (a first protruding portion 413 and a second protruding portion 431) formed on an inner peripheral surface thereof that come into contact with an outer peripheral surface of the inner cable 32, and having a first insertion hole 44 through which the inner cable 32 is inserted; and a washer member (5) that is disposed on the other end side of the seal member (4) and that suppresses deviation of the inner cable (32) in a vertical direction relative to the axis (O).

[0034] According to the control cable 1 of (1) above, in the event that the inner cable 32 advancing from the casing cap 2 to the outside becomes biased, the washer member 5 arranged on the other end side closest to the outside in the inner seal portion 21 of the casing cap 2 suppresses bias of the inner cable 32 (bias in a direction perpendicular to the axis O) that may occur due to a load acting in a direction perpendicular to the axis O. Also, the inner cable 32 is sealed in a watertight state by the abutment of the outer circumferential surface of the inner cable 32 with the lip portion (first protruding portion 413, second protruding portion 431) of the seal member 4. This enables the control cable 1 equipped with the casing cap 2 to have a higher waterproof function than ever before.

[0038] According to the above configuration (3), the washer member 5 moves in a direction perpendicular to the axis O as the inner cable 32 bends, and even if stress from the inner cable 32 acts on the washer member 5, the washer member 5 moves due to the gap in the overlapping portion, thereby reducing the stress. This enables the control cable 1 equipped with the casing cap 2 to have an even higher waterproof function.

[0039] (4) The sealing member 4 is a first seal portion 41 disposed on the washer member 5 side and having a first protruding portion 413 protruding radially inward and formed as a lip portion in an annular shape in the circumferential direction of the inner wall surface; a second seal portion 43 disposed on the opposite side to the washer member 5 side, the second protruding portion 431 protruding radially inwardly is formed as a lip portion in an annular shape in the circumferential direction of the inner wall surface, The inner diameter L2 of the second protrusion 431 is smaller than the inner diameter L1 of the washer member 5 and is larger than the inner diameter L3 of the first protrusion 413. The control cable 1 according to any one of (1) to (3) above.

[0040] According to the above configuration (4), the second seal portion 43 ensures sealing performance, and the first protruding portion 413 ensures the conformability of the inner cable 32, so that sealing performance and slidability can be ensured.

[0041] (5) The sealing member 4 is The inner seal portion 21 has an outer circumferential lip portion 432 (lip portion) on its outer circumferential surface, the outer circumferential lip portion 432 being in close contact with the inner wall surface of the through hole 24. The control cable 1 according to any one of (1) to (4) above.

[0042] According to the above configuration (5), the sealing member 4 can be fixed to the casing cap 2, and water that infiltrates through the gap between the sealing member 4 and the casing cap 2 can be blocked at the close contact portion of the outer circumferential lip portion 432 (lip portion).

[0043] The control cable 1 according to the present invention may be configured only with the configuration described in (1) above, or may be configured by any combination of the configuration described in (1) above and any of the configurations described in (2) to (5) above, within a range in which matching can be achieved.
