  However, in such a conventional cable holding device 100, when a defect such as breakage occurs in the comb feather, it is necessary to replace the clamp ring 110 itself. Further, since the inner diameter of the insertion path 112 that can be formed by the comb feather 109 is set in advance to a predetermined size only by the comb feather 109, it has not been possible to flexibly cope with cables having different outer diameters. .

  The present invention has been made in order to solve such problems in the prior art, and it is not necessary to replace the clamp ring itself even when a defect such as breakage occurs in the comb wings. It is an object of the present invention to provide a cable holding device that can use the same device for other cables.

The present invention is a base having an insertion hole through which a cable is inserted, and a press-contact holding member that press-holds the cable, and communicates with the insertion hole at one end of the insertion hole of the base along the cable direction.

A plurality of cantilever-like first elastic pieces that can extend to form a first insertion path communicating with the annular portion, and the one end from the other end side opposite to the first elastic piece A second insertion path extending from the annular portion along the cable direction along the cable direction from the one end side toward the other end side and extending along the cable direction from the annular portion and communicating with the annular portion. Cantilever can be formed The pressure contact holding member having a plurality of second elastic pieces, and attached to the base at one end side of the insertion hole of the base, and from the annular portion toward the one end side from the other end side Either one of the first elastic piece or the second elastic piece extending along the cable direction is brought into contact with the first insertion path or the second insertion path to reduce the diameter. A cable holding device is provided that includes an attachment member and a rotation preventing member that prevents relative rotation between the pressure contact holding member and the base .
According to this configuration, by providing two insertion holes on both sides of the annular portion, it is possible to cope with various usage modes according to the usage situation.
The cable holding device of the present invention is used for cables having different outer diameters, and when used for a cable having a relatively small outer diameter, the first elastic piece is moved from the other end side to the one end side. A first insertion path extending along the cable insertion direction from the annular portion is formed, and the second elastic piece is opposite to the first elastic piece from the one end side to the other end side. Forming a second insertion path extending from the annular portion along the cable insertion direction, the mounting member abutting against the first elastic piece to reduce the diameter of the first insertion path, When the cable is used for a cable having a large outer diameter, the first elastic piece has a first insertion path extending from the annular portion along the cable insertion direction from the one end side toward the other end side. Forming the second elastic piece, the first elastic piece On the contrary, a second insertion path extending from the annular portion along the cable insertion direction from the other end side toward the one end side is formed, and the attachment member is in contact with the second elastic piece. To reduce the diameter of the second insertion path. Further, in the cable holding device, a rotation preventing member for preventing relative rotation between the pressure contact holding member and the base portion is provided to prevent relative rotation between the pressure contact holding member and the base portion. When the attachment member is fixed to the base, it is possible to prevent the cable from being disconnected due to the rotation of the pressure contact holding member.

In the cable holding device, the inner diameter of the first insertion path and the inner diameter of the second insertion path may be different from each other.
By making the size of the inner diameter different between the insertion holes, it is possible to flexibly cope with cables having different diameters only by changing the direction in which the pressure contact holding member is assembled to the base.

In the cable holding device, the plurality of first elastic pieces have the same size and shape, the plurality of second elastic pieces have the same size and shape, and the plurality of first elastic pieces. The total number of one elastic piece and the total number of the plurality of second elastic pieces may be different from each other.
By making the total number of elastic pieces different, the pressure contact holding force of the cable can be easily adjusted.

Further, in the cable holding device, the plurality of first elastic pieces have the same size and shape, the plurality of second elastic pieces have the same size and shape, and the plurality of first elastic pieces have the same size and shape. The width of each elastic piece in the circumferential direction of the annular portion and the width of each of the plurality of second elastic pieces in the circumferential direction of the annular portion may be different from each other.
By making the widths of the elastic pieces different, the pressure contact holding force of the cable can be easily adjusted.

  Furthermore, in the cable holding device, the first insertion path is tapered toward the free end side of the first elastic piece, or the second insertion path is the second insertion path. It may be tapered toward the free end of the elastic piece.

Further, in the above cable holding device, the pressure contact portion for the cable provided near the free end of the first elastic piece or the pressure contact portion for the cable provided near the free end of the second elastic piece is rounded. It may be provided.
According to this configuration, even when a cable having an outer diameter larger than the inner diameter of the insertion hole is inserted, the cable is not damaged by the elastic piece.

The cable holding device may further include an annular waterproof member sandwiched between a part of the base and the press-contact holding member in a state where the cable holding device communicates with the insertion hole.
Thereby, a waterproof function can also be added by providing a waterproof member.

Further, in the cable holding device, a contact portion that can contact the waterproof member is provided near the free end of the first elastic piece of the pressure contact holding member, or near the free end of the second elastic piece. A contact portion that can contact the waterproof member may be provided.
By providing the contact surface, the waterproof member can be pressed against the base by pressing the press-contact holding member against the waterproof member.

Still further, in the cable holding device, the thickness of the contact portion of the first elastic piece or the contact portion of the second elastic piece in the radial direction of the insertion hole may be the annular portion and the first portion. It may be larger than the thickness in the radial direction of the insertion hole in the vicinity of the connection portion with the elastic piece or in the vicinity of the connection portion between the annular portion and the second elastic piece.
According to this configuration, the contact surface can be made larger.

  According to the present invention, there is provided a cable holding device in which it is not necessary to replace the clamp ring itself even when a defect such as breakage occurs in the comb feather, and the same device can be used for cables of different diameters. .

It is a perspective view which shows the cable holding device by this invention with a connector. It is a side view of FIG. It is a front perspective view of a clamp member. It is a rear side perspective view of a clamp member. It is a side view of a clamp member. It is the II sectional view taken on the line of FIG. It is a figure corresponding to Drawing 1, and is a figure showing the mode of use which changed the thickness of the cable. It is a figure corresponding to Drawing 2, and is a figure showing the mode of use which changed the thickness of the cable. It is process drawing which showed the state before clamp | tightening a clamping cap to a clamp member. It is process drawing which showed the state after clamp | tightening the clamping cap to the clamp member. FIG. 10 is a diagram corresponding to FIG. 9 and a process diagram when the thickness of the cable is changed. It is a figure corresponding to FIG. 10, Comprising: It is process drawing when the thickness of a cable is changed. It is a disassembled perspective view which shows the conventional cable holding device.

A preferred embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a cable holding device 1 according to the present invention together with a connector 10, and FIG. 2 is a lateral view thereof. In the state shown in these drawings, the components constituting the cable holding device 1 are merely inserted through the cable 3 and are not yet assembled to each other.

  The connector 10 is fixed to one end of the cable 3 and is connected to a mating connector (not shown) at the distal end portion 13 thereof. For connection with the mating connector, for example, bayonet connection can be used.

  In general, the connection between the connector 10 and the cable 3 is not so strong. For this reason, when the cable 3 is pulled, the cable 3 is detached from the connector 10 relatively easily. When the cable holding device 1 is provided, the cable 3 can be held by the cable holding device 1 and the cable holding device 1 holding the cable 3 can be fixed to the connector 10. Power can be efficiently dispersed. Therefore, accidents such as the cable 3 being disconnected from the connector 10 can be reduced.

  The cable holding device 1 includes a cord tube (base portion) 20, a tightening cap (mounting member) 40 attached to the cord tube 20, and a gasket 50 (inside the cord tube 20 and the tightening cap 40 ( A waterproof member) and a clamp member (pressure contact holding member) 60 are included.

  The cord tube 20 is a substantially cylindrical member, and has an insertion hole 29 through which the cables 3 and 4 are inserted. A screw 21 for fixing the screw to the connector 10 is cut on the front outer wall, and a screw 22 for fixing the screw to the tightening cap 40 is cut on the rear outer wall. A notch 28 is further provided in a part of the outer wall of the rear end where the screw 22 is cut. When the clamp member 60 is attached to the cord tube 20, a predetermined portion (the rotation prevention member 69) of the clamp member 60 is fitted into the notch 28. As a result, relative rotation between the clamp member 60 and the cord tube 20 is prevented.

  The gasket 50 is an annular elastic member having a symmetrical shape in the front-rear and left-right directions. In the center of the annular portion of the gasket 50, a recess 51 is provided along the circumferential direction (the arrow “β” direction in the figure), and the gasket 50 communicates with the insertion hole 29 of the cord tube 20. It is disposed at a position sandwiched between a part of the cord tube 20 (the flange 23 shown in FIG. 9 and the like) and the clamp member 60. By providing the gasket 50, a waterproof function can be added.

  The clamp member 60 is used to clamp the cable 3 in cooperation with the fastening cap 40. 3 to 6 are individual views of the clamp member 60 in perspective views. 3 is a front perspective view of the clamp member 60, FIG. 4 is a rear perspective view thereof, FIG. 5 is a lateral view thereof, and FIG. 6 is a cross-sectional view taken along line II of FIG.

The clamp member 60 includes an annular flange 61 and a plurality of cantilevered elastic pieces, for example, comb feathers 63 and 65, provided in a state of being continuous with the annular flange 61.
The annular flange 61 is disposed on one end side of the insertion hole 29 of the cord tube 20 so as to communicate with the insertion hole 29. The plurality of comb feathers 63 and 65 extending from the annular flange 61 extend in opposite directions to each other along the cable direction (arrow “α” in the drawing) on both sides of the annular flange 61. The comb feather includes a plurality of comb feathers 63 constituting one group and a plurality of comb feathers 65 constituting another group.

  The plurality of comb feathers 63 constituting one group may have the same size and shape. Similarly, the plurality of comb feathers 65 constituting another group may have the same size and shape. The plurality of comb feathers 63 and the plurality of comb feathers 65 may have the same size and shape, but may have different sizes and shapes. For example, in the illustrated example, the width of the arc-shaped portion along the circumferential direction “β” in each of the plurality of comb wings 63 is relatively small, and the number of the combs is relatively large as 16 sheets. The width of the arc-shaped portion along the circumferential direction “β” in each of the wings 65 is relatively large, and the number thereof is relatively small as six. The shape, size, and number of the plurality of comb wings 63 and the plurality of comb wings 65 can be freely controlled by the designer within an allowable range in relation to the thickness (outer diameter) of the cable to be clamped. Can be decided.

  The plurality of comb feathers 63 and 65 can form insertion paths 83 and 85 communicating with the annular flange 61, respectively. The cable 3 is inserted through the insertion paths 83 and 85 together with the annular flange 61. Each of the insertion paths 83 and 85 may be tapered toward the free end side. In the illustrated example, only the insertion path 83 is tapered, and the insertion path 85 is made upright with respect to the annular flange 61 while maintaining the size of the diameter. The diameters of the insertion paths 83 and 85 are determined by the shapes and sizes of the plurality of comb feathers 63 and the plurality of comb feathers 65. For example, as shown in FIG. May be set smaller than the inner diameter “b” of the insertion path 85. When the inner diameter is made different between the insertion path 83 and the insertion path 85 in this way, the present apparatus is applied to cables having different outer diameters only by changing the direction in which the clamp member 60 is assembled to the cord tube 20. The advantage that it can be obtained. This point will be specifically described with reference to FIGS.

  FIGS. 7 and 8 are views corresponding to FIGS. 1 and 2, respectively, but are different from those shown in FIGS. 1 and 2 in the cable used and the clamp member 60 for the cord tube 20. The installation direction is different. The outer diameter “e” of the cable 4 shown in FIGS. 7 and 8 is larger than the outer diameter “d” of the cable 3 shown in FIGS. For example, when this device 1 is applied to the cable 4 having a large outer diameter, the inner diameter “a” (see FIG. 6) of the insertion path 83 is too small compared to the outer diameter “e” of the cable 4. In this apparatus, it is necessary to newly prepare a clamp member having a larger inner diameter. However, according to the present apparatus 1, the insertion path 85 having an inner diameter “b” larger than the inner diameter “a” of the insertion path 83 can accommodate the outer diameter “e” of the cable 4. Without being provided, the same device 1 can be applied to the cable 4 simply by changing the direction in which the clamp member 60 is assembled to the cord tube 20.

  Thus, in this apparatus, the direction in which the clamp member 60 is assembled with the cord tube 20 can be freely changed in accordance with the outer diameter of the cable used. As shown in FIGS. 1 and 2, when the present apparatus 1 is applied to the cable 3 having a relatively small outer diameter, the plurality of comb feathers 63 are connected to the one end side “B” from the other end side “B” of the insertion hole 29. The plurality of comb feathers 65 are arranged so as to extend toward A ”and so as to extend from one end side“ A ”of the insertion hole 29 toward the other end side“ B ”. On the other hand, as shown in FIGS. 7 and 8, when the present apparatus 1 is applied to the cable 4 having a relatively large outer diameter, the insertion holes of the plurality of comb feathers 63 are opposite to the case of the cable 3. 29 extending from one end side “A” to the other end side “B”, and the plurality of comb feathers 65 from the other end side “B” of the insertion hole 29 toward the one end side “A”. Arrange them so that they extend.

  Although not particularly illustrated, the plurality of comb wings 63 and the plurality of comb wings 65 may be exactly the same, that is, the clamp member 60 may be symmetrical with respect to the annular flange 61. When the clamp member 60 has a left-right symmetric shape, the two insertion paths have the same inner diameter and cannot correspond to cables having different outer diameters. For example, one insertion path is formed. When the comb feather (63 or 65) is broken, there is an advantage that repair can be performed without changing the clamp member only by changing the assembly direction of the clamp member.

  As shown in FIGS. 7 and 8, when the inner diameter “a” of the insertion path 83 is smaller than the outer diameter “e” of the cable 4, the cable 4 displaces the plurality of comb blades 63 forming the insertion path 83. It is inserted through the insertion path 83. Obviously, in this case, since the comb feathers 63 come into contact with the cable 4, the surface of the cable 4 is damaged by the comb feathers 63. In order to prevent scratches, the pressure contact portion (tip edge) 64 for the cable provided near the free end of the comb wing 63 and the pressure contact portion (tip end) for the cable provided near the free end of the comb wing 65 for the same reason. The edge 70 may be rounded. However, the size and shape of the roundness should be such that cable clamping is not insufficient or impossible.

  In order to cope with a change in the direction in which the clamp member 60 is assembled to the cord tube 20, the clamp member 60 has a symmetrical shape with the annular flange 61 as the center except for the shapes related to the comb feathers 63 and 65. For example, the anti-rotation member 69 provided corresponding to the notch 28 of the cord tube 20 is also provided as an anti-rotation member 67 on the opposite side across the annular flange 61.

  When the component members are assembled, the clamp member 60 abuts on the gasket 50 in the vicinity of the tips of the comb feathers 65 and 63 of the clamp member 60 and moves the gasket 50 to the inside of the cord tube 20. Flat abutting portions 72 and 74 that can abut against the annular surface 53 of the gasket 50 are provided near the free ends of the comb feathers 65 and 63 of the clamping member 60 so that the clamping member 60 and the gasket 50 abut more securely. It may be provided. In order to increase the contact area, the thickness of the contact portion in the radial direction of the insertion hole may be set large. For example, as shown in FIG. 6, the thickness “f” of the contact portion 74 of the comb blade 63 in the radial direction of the insertion hole is set to the insertion hole in the vicinity of the connection portion between the annular flange 61 and the plurality of comb blades 63. It is also possible to ensure a large abutting portion by setting it to be larger than the thickness “g” in the radial direction.

  The tightening cap 40 is screwed to the cord tube 20 while including the clamp member 60 and the gasket 50. The fastening cap 40 has a substantially cylindrical shape with a reduced diameter at the rear end in order to easily come into contact with the comb feathers 63 and 65 of the clamp member 60. The tightening cap 40 is screwed to the cord tube 20 using the screw 22 cut on the rear outer wall of the cord tube 20. Corresponding to the screw 22 of the cord tube 20, a screw (an “inner screw portion 42” shown in FIG. 9) is cut on the inner wall of the fastening cap 40.

Next, referring to FIGS. 1 and 2 again, a method for assembling the constituent members will be described.
After the state shown in FIGS. 1 and 2, the cord tube 20 is slid along the cable 3 toward the connector 10, and a threaded portion 21 cut on the front outer wall of the cord tube 20 and a nut 11 provided on the connector 10. The cord tube 20 is screwed to the connector 10 using the screw portion 12 cut in the inner wall of the cable.

  Next, the gasket 50 and the clamp member 60 are moved to the connector 10 side as much as possible along the cable direction “α”. When the cord tube 20 and the tightening cap 40 are screwed, the gasket 50 is completely accommodated in the cord tube 20, whereas the clamp member 60 has a front protrusion of the annular ring flange 61. Since the abutment surface 68 and the rear end abutment surface 26 of the cord tube 20 collide, they are not inserted into the cord tube 20 beyond the collision position. At this time, since the rotation preventing projection 69 provided on the annular flange 61 of the clamp member 60 is inserted into the notch 28 of the cord tube 60, the clamp member 60, the cord tube 20 and the Are not relatively rotated. As a result, for example, when the fastening cap 40 is screwed to the cord tube 20, the clamping member 60 rotates with respect to the cables 3 and 4 together with the fastening cap 40, and the cables 3 and 4 are cut by the clamping member 60. Accidents such as accidents can be prevented.

  Finally, the screw portion (the inner screw portion 42 shown in FIG. 9 and the like) of the tightening cap 40 is attached to the rear end of the cord tube 20 with a screw so as to wrap the exposed portion of the clamp member 60, thereby completing the assembly. It should be noted that the screwing amount of the tightening cap 40 is not always the same, and it is necessary to adjust according to the situation such as the outer diameter of the cable.

  Next, with reference to FIG. 9 to FIG. 12, a process of pressing and holding the cables 3 and 4 by the comb blades 63 and 65 of the clamp member 60 will be described. 9 and 10 show the state of the cable 3 having a relatively small outer diameter before and after the fastening cap 40 is fastened to the clamp member 60, that is, the state before and after screwing, along the cable 3. FIGS. 11 and 12 are cross-sectional views corresponding to FIGS. 9 and 10, respectively, and show the cable 4 having a relatively large outer diameter before and after the fastening cap 40 is fastened to the clamp member 60. The state is shown by a cross section along the cable 4.

  As shown in FIGS. 9 and 10, the comb feather 63 having a relatively small inner diameter “a” is used for the cable 3 having a relatively small outer diameter “d”. In this case, the clamp member 60 attached to one end side “A” of the insertion hole 29 of the cord tube 20 along the cable direction “α” is put in another way so that the comb blade 63 faces the attachment side of the fastening cap 40. Then, the comb feather 63 is set so as to extend from the other end side “B” of the insertion hole 29 toward the one end side “A”. After the setting, first, the clamp member 60 is moved in the direction from the one end side “A” of the cord tube 20 toward the other end side “B”. At this time, the gasket 50 abuts against the abutment surface 72 of the comb feather 65 of the clamp member 60 at one annular surface 53, and abuts against the internal flange 23 of the cord tube 20 at the other annular surface 54. . After this state, when the fastening cap 40 is screwed into the cord tube 20, the taper 44 provided on the inner wall of the rear end of the fastening cap 40 comes into contact with a part of the comb feather 63 and through this contact. The insertion path 83 that can be formed by the comb feathers 63 is reduced in diameter (“a ′” in FIG. 10) and is pressed against the cable 3. At the same time, the clamp member 60 moves together with the fastening cap 40 to the other end side “B”, that is, the gasket 50 side. When the screwing further proceeds, the front abutting surface 68 of the annular annular flange 61 of the clamp member 60 and the rear end abutting surface 26 of the cord tube 20 collide, and the tightening is finished. When the tightening is completed, the inner wall flange 45 of the tightening cap 40 is in a state of colliding with the side surface 67 ′ of the rotation preventing member 67, and the gasket 50 is compressed between the inner flange 23 and the contact surface 72 of the comb feather 65. And is in close contact with the cable 3. Obviously, under this state, the pressure contact portions 64 of the plurality of comb feathers 63 are pressed against the cable 3 and the gasket 50 is elastically adhered to the cable 3, so that these connections are made. Thus, the cable holding device 1 is firmly held by the cable 3. Further, since the gasket 50 is in close contact with the cable 3, water does not enter the other end side “B” from these close contact points.

  As shown in FIGS. 11 and 12, for the cable 4 having a relatively large outer diameter “e”, comb blades 65 having a relatively large inner diameter “b” are used. The main operation is as described above with reference to FIGS. Therefore, detailed description is omitted. If the inner diameter (“a” in FIG. 6) of the insertion path 83 is smaller than the outer diameter “e” of the cable 4, there is a problem that the cable 4 is damaged as described above. Since the cable 4 is in a state in which the plurality of comb feathers 63 are displaced, the cable 4 is temporarily held by the plurality of comb feathers 63. Therefore, in this case, the cable holding device 1 is held more firmly with respect to the cable 4.

  It can be widely used for press-clamping of cables using a clamp ring.
