DETAILED DESCRIPTION OF THE INVENTION

[0010] A first embodiment of the present invention will be described below with reference to FIGS. As shown in Fig. 1, a cable 5 is connected to the actuator 1 according to the first embodiment via a cable connector 3. The actuator 1 receives power and control signals via the cable connector 3 and the cable 5.

[0011] As shown in FIG. 2, the cable connector 3 is installed on the base end side of the cable connector cover 11, and the cable 5 is drawn out from the tip end side of the cable connector cover 11. The cable connector cover 11 is composed of a cable connector cover body 13 on which the cable connector 3 is installed, and a cable take-out member 15 which is rotatably installed relative to the cable connector cover body 13 and through which the cable 5 is pulled out.

[0012] As shown in Figures 3 and 4, the cable connector cover main body 13 has a hollow shape that opens in the left-right direction in Figure 3 and is composed of a cable connector cover main body element 21 and a cable connector cover main body element 23. The cable connector cover main body element 21 forms the upper side of the cable connector cover main body 13 in Figure 3, and as shown in Figure 4, an engaging protrusion 25 is formed on the lower side in Figure 4. The cable connector cover main body element 23 forms the lower side of the cable connector cover main body 13 in Figure 3, and as shown in Figure 4, an engaging recess 27 that opens on the upper side and side in Figure 4 is formed. The cable connector cover main body element 21 and the cable connector cover main body element 23 are integrated by inserting and engaging the engaging protrusion 25 of the cable connector cover main body element 21 into the engaging recess 27 of the cable connector cover main body element 23 from the upper side in Figure 4. The base end side (left side in Figure 4) of the cable connector 3 is inserted and held between the cable connector cover main body element 21 and the cable connector cover main body element 23.

[0013] Cable connector engaging recesses 31, 31 are formed on the right side of the cable connector cover main body element 21 in Figure 4, and a cable connector engaging recess 33 is formed on the right side of the cable connector cover main body element 23 in Figure 4. Engaging protrusions 35, 35 (engaging protrusion 35 on the back side in Figure 4 is hidden and not visible) are formed on the upper side of the base end side (left side in Figure 4) of the cable connector 3 in Figure 4, and engaging protrusions 37, 37 (engaging protrusion 37 on the back side in Figure 4 is hidden and not visible) are formed on the lower side of the base end side (left side in Figure 4) of the cable connector 3 in Figure 4. The engaging protrusions 35, 35 engage with the cable connector engaging recesses 31, 31, and the engaging protrusions 37, 37 engage with the cable connector engaging recess 33, preventing the cable connector 3 from falling off.

[0014] A cable takeout member through hole 41 having a substantially circular cross section is formed on the left side of the cable connector cover main body 13 in Figure 3. The right side of the cable connector cover main body 13 in Figure 3 has a reduced diameter to form a rotation shaft engaging portion 43. As described above, the cable connector cover main body 13 is made up of the cable connector cover main body element 21 and the cable connector cover main body element 23, so the cable takeout member through hole 41 is made up of a cable connector cover main body element 45 on the cable connector cover main body element 21 side and a cable connector cover main body element 47 on the cable connector cover main body element 23 side, and the rotation shaft engaging portion 43 is made up of a rotation shaft engaging portion element 49 on the cable connector cover main body element 21 side and a rotation shaft engaging portion element 51 on the cable connector cover main body element 23 side.

[0015] As shown in Fig. 5(a), a stopper 53 is formed in the through-hole element 47 for the cable extracting member of the cable connector cover main body element 23. Also, as shown in Fig. 5(b), the inner peripheral surface of the rotation shaft engaging portion 43 is substantially annular, and click recesses 55 are formed at four equally spaced locations.

[0016] As shown in FIG. 3, the cable take-out member 15 has a hollow shape that is open to the right and bottom in FIG. 3. A rotating shaft 61 having a circular cross section is formed on the right side of the cable take-out member 15 in FIG. 3. This rotating shaft 61 is disposed in the cable take-out member through-hole 41. As shown in FIG. 5, the rotating shaft 61 is formed with a click protrusion 62 that engages with the click recess 55. This prevents the cable take-out member 15 from rotating at every 90°. The inner circumferential surface of the rotating shaft engaging portion 43 has an expanded diameter between the click recesses 55, 55, forming spaces 66, 66, 66, 66. This allows the click protrusion 62 to easily move between the click recesses 55, 55 when the rotating shaft 61 rotates. As shown in FIG. 3, the outer circumferential side of the right end of the rotating shaft 61 in FIG. 3 is expanded in diameter to form a flange portion 63. The flange portion 63 is engaged with the right side of the rotary shaft engaging portion 43 of the cable connector cover main body 13 in Fig. 3. As shown in Fig. 5, a stopper 64 is formed on the rotary shaft 61, and when it comes into contact with the stopper 53, the cable take-out member 15 is prevented from rotating more than one turn.

[0017] As shown in FIG. 5, the surface of the stopper 64 on the counterclockwise side in the circumferential direction (the surface on the left side in FIG. 5(a)) is inclined toward the counterclockwise side (the left side in FIG. 5(a)), and the surface of the stopper 53 on the clockwise side in the circumferential direction (the surface on the left side in FIG. 5(a)) is also inclined toward the clockwise side (the left side in FIG. 5(a)). When the rotating shaft 61 is rotated counterclockwise in FIG. 5(a) and the stopper 64 and the stopper 53 come into contact with each other, the stopper 64 climbs over the stopper 53, making it difficult for the rotating shaft 61 to rotate further. Furthermore, the height (vertical dimension in FIG. 5(a)) of the end of the stopper 53 on the counterclockwise side of the circumference (right side in FIG. 5(a)) is set to be greater than the height (vertical dimension in FIG. 5(a)) of the end of the stopper 64 on the clockwise side of the circumference (right side in FIG. 5(a)). When the rotating shaft 61 rotates clockwise in FIG. 5(a) and the stopper 64 and the stopper 53 come into contact, the stopper 64 climbs over the stopper 53, making it difficult for the rotating shaft 61 to rotate further. 3, a wiring through-hole 65 extending in the axial direction (left and right direction in FIG. 3) is formed inside the rotating shaft 61. Wiring (not shown) drawn out from the cable connector 3 is passed through this wiring through-hole 65.

[0018] A cable outlet 67 is formed on the lower side of the cable outlet member 15 in Fig. 3. The cable outlet 67 has an engagement recess 69 formed therein. A bellows boot 71 is installed at the cable outlet 67. The wiring (not shown) drawn out from the cable connector 3 is drawn out to the cable 5 side (lower side in FIG. 3 ) via the cable outlet 67 and the bellows boot 71. The bellows boot 71 is formed with an engaging protrusion 73 that engages with the engaging recess 69 .

[0019] As shown in Fig. 4, the cable takeout member 15 is composed of a cable takeout member main body element 81 and a cable takeout member element 83. The cable takeout member main body element 81 includes a rotation shaft element 80, which is the upper part of the rotation shaft 61 in Fig. 3, and an engagement recess element 82, which is the left part of the engagement recess 69 in Fig. 3, while the cable takeout member element 83 includes a rotation shaft element 84, which is the lower part of the rotation shaft 61 in Fig. 3, and an engagement recess element 86, which is the right part of the engagement recess 69 in Fig. 3. That is, when attaching the bellows boot 71 to the cable takeout member 15, the bellows boot 71 is engaged with the cable takeout member main body element 81, and then the cable takeout member element 83 is attached to the cable takeout member main body element 81. In this way, by separating the cable takeout member main body element 81 and the cable takeout member element 83 and making part of the engagement recess 69 separable as the engagement recess element 86, attachment of the bellows boot 71 is facilitated. Furthermore, even if the cable take-out member element 83 can be separated from the cable take-out member 15, the complete rotation shaft 61 is configured from the rotation shaft element 80 and the rotation shaft element 84, so stability can be ensured when rotating the cable take-out member 15 or when fixing its position.

[0020] 4, for example, cable takeoff member element engaging recesses 85, 85 (one of the cable takeoff member element engaging recesses 85 is not shown in FIG. 4) are formed on both sides in the width direction of the cable takeoff member main body element 81, and cable takeoff member element engaging protrusions 87, 87 are formed on the cable takeoff member element 83. When the cable takeoff member element 83 is attached to the cable takeoff member main body element 81, the cable takeoff member element engaging protrusions 87, 87 are engaged with the cable takeoff member element engaging recesses 85, 85. Claws 89, 89 protruding inward (on the side facing the cable take-out member element engaging protrusions 87, 87) are formed at the tips of the cable take-out member element engaging protrusions 87, 87, and the cable take-out member element 83 is fixed to the cable take-out member main body element 81 by engaging the claws 89, 89 with claw engaging recesses 91, 91 (one of the claw engaging recesses 91 is not shown in Figure 4) formed in the cable take-out member element engaging recesses 85, 85.

[0021] Next, the operation of the first embodiment will be described. The cable take-out member 15 is rotatably installed on the cable connector cover body 13 by the rotation shaft 61, so that the user can change the direction in which the cable 5 is taken out by rotating the cable take-out member 15. The cable 5 can be pulled out in four directions at 90-degree intervals by the click protrusions 62 of the rotating shaft 61 and the click recesses 55 of the cable connector cover main body 13. The portion between the click recesses 55, 55 on the inner circumferential surface of the rotating shaft engaging portion 43 is expanded in diameter to provide a space 66, which makes it easy for the click protrusions 62 to move between the click recesses 55, 55 when the rotating shaft 61 rotates. The cable connector cover body 13 has a stopper 53, and the rotation shaft 61 has a stopper 64, so that the cable take-out member 15 does not rotate more than one revolution relative to the cable connector cover body 13. This prevents the cable 5 from twisting.

[0022] Next, the effects of the first embodiment will be described. The cable take-out member 15 is rotatably mounted on the cable connector cover body 13 via the rotation shaft 61, so that the user can easily rotate the cable take-out member 15 with a simple configuration to change the direction in which the cable 5 is taken out, as shown in Figures 1 and 6. Since the rotation shaft 61 has a click protrusion 62 and the cable connector cover main body 13 has a click recess 55, the pull-out direction of the cable 5 can be positioned in four directions at 90-degree intervals. In addition, since a space 66 is provided through which the click protrusion 62 passes when the cable extracting member 15 is rotated, the pull-out direction of the cable 5 can be changed smoothly. In addition, the cable connector cover body 13 has a stopper 53, and the rotating shaft 61 has a stopper 64, so the cable take-out member 15 does not rotate more than one revolution relative to the cable connector cover body 13, preventing twisting of the cable 5.

[0023] A second embodiment of the present invention will now be described with reference to FIGS. As shown in FIG. 7, like the actuator 1 in the first embodiment described above, the actuator 101 in this second embodiment also allows the user to change the direction in which the cable 5 is pulled out using the cable connector cover 111.

[0024] The cable connector cover 111 is composed of a cable connector cover body 113 on which the cable connector 3 is installed, and a cable take-out member 115 which is rotatably installed relative to the cable connector cover body 113 and through which the cable 5 is pulled out.

[0025] As shown in Figures 8 to 10, the cable connector cover main body 113 has a hollow shape that is open in the left-right direction in Figure 3, and is composed of a cable connector cover main body element 121 and a cable connector cover main body element 123. The cable connector cover main body element 121 forms the upper side of the cable connector cover main body 113 in Figure 9, and as shown in Figure 10, an engaging protrusion 125 is formed on the lower side in Figure 10. The cable connector cover main body element 123 forms the lower side of the cable connector cover main body 113 in Figure 9, and as shown in Figure 10, an engaging recess 127 that is open on the upper side and side in Figure 10 is formed. The cable connector cover main body element 121 and the cable connector cover main body element 123 are integrated by inserting and engaging the engaging protrusion 125 of the cable connector cover main body element 121 into the engaging recess 127 of the cable connector cover main body element 123 from the upper side in Figure 10. The base end side (left side in FIG. 10) of the cable connector 3 is inserted and held between the cable connector cover main body element 121 and the cable connector cover main body element 123 .

[0026] Cable connector engaging recesses 131, 131 are formed on the right side of the cable connector cover main body element 121 in Figure 10, and a cable connector engaging recess 133 is formed on the right side of the cable connector cover main body element 123 in Figure 10. The engaging protrusions 35, 35 of the cable connector 3 are engaged with the cable connector engaging recesses 131, 131, and the engaging protrusions 37, 37 of the cable connector 3 are engaged with the cable connector engaging recess 133, so that the cable connector 3 will not fall off.

[0027] A through hole 141 for a cable take-out member having a substantially rectangular cross section is formed on the left side of the cable connector cover body 113 in Figure 9. A cable take-out member engaging recess 143 is formed on each side of the through hole 141 for a cable take-out member. As mentioned above, the cable connector cover main body 113 is composed of the cable connector cover main body element 121 and the cable connector cover main body element 123, and therefore the cable take-out member engaging recess 143 in the left-right direction in Figure 10 is composed of a cable take-out member engaging recess element 145 on the cable connector cover main body element 121 side and a cable take-out member engaging recess element 147 on the cable connector cover main body element 123 side.

[0028] The cable takeout member 115 has the same configuration as the cable takeout member 15 in the first embodiment described above, but a cable takeout opening 149 is formed on one of the side surfaces of the cable takeout member 115, and a cable takeout member fixing claw 151 that engages with the cable takeout member engaging recess 143 of the cable connector cover main body 113 is provided on the side surface of the cable takeout member 115 on which the cable takeout opening 149 is not formed. The cable takeout member fixing claw 151 is disposed in a fixing claw accommodating portion 153 that is formed on each of the side surfaces of the cable takeout member 115 on which the cable takeout opening 149 is not formed, and an engaging portion 155 is formed on the tip side.

[0029] The cable takeout member 115 is inserted into the cable connector cover main body 113 from the cable takeout member through-hole 141 side (left side in FIG. 9 ), and is fixed by engaging the engagement portion 155 of the cable takeout member fixing claw 151 with the cable takeout member engaging recess 143 of the cable connector cover main body 113. When the cable takeout member fixing claw 151 is engaged with the cable takeout member engaging recess 143, the cable takeout member fixing claw 151 is elastically deformed inward.

[0030] The cable take-out member engaging recess 143 is formed on each side of the cable take-out member through hole 141, and the cable take-out member fixing claws 151 are provided on the sides of the cable take-out member 115 on which the cable take-out opening 149 is not formed. Therefore, even if the orientation of the cable take-out member 115 is changed, the cable take-out member fixing claws 151 engage with any of the cable take-out member engaging recesses 143, and the orientation of the cable take-out member 115 can be selected from four directions every 90 degrees.

[0031] In the second embodiment, the same actions and effects as in the first embodiment are achieved.

[0032] Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. The cable connector cover 201 according to the third embodiment has a configuration substantially similar to that of the cable connector cover 11 according to the first embodiment described above, but has a male thread portion 211 formed on the rotating shaft 61 and a female thread portion 213 formed in the through hole 41 for the cable extracting member. As shown in FIG. 11, the male thread portion 211 of the rotary shaft 61 has four threads formed thereon, and the female thread portion 213 of the through-hole 41 for the cable extracting member has three threads formed thereon.

[0033] As shown in FIG. 12, similarly to the first embodiment, in the third embodiment, the cable take-out member 15 is composed of a cable take-out member main body element 81 and a cable take-out member element 83, and the cable take-out member main body element 81 side includes a male thread element 215 which is the upper part of the male thread portion 211 in FIG. 12, and the cable take-out member element 83 side includes a male thread element 217 which is the lower part of the male thread portion 211 in FIG. 12. Furthermore, since the cable connector cover main body 13 is composed of a cable connector cover main body element 21 and a cable connector cover main body element 23, the cable connector cover main body element 21 side includes a female thread element 219 which is the lower part of the female thread portion 213 in Figure 12, and the cable connector cover main body element 23 side includes a female thread element 221 which is the upper part of the female thread portion 213 in Figure 12.

[0034] With this configuration, by rotating the cable outlet member 15 relative to the cable connector cover body 13, the direction in which the cable 5 is drawn out can be changed. Furthermore, when the cable takeout member 15 is rotated, the cable takeout member 15 approaches or moves away from the cable connector cover main body 13. The cable takeout member 15 can approach the cable connector cover main body 13 until it abuts against the cable connector cover main body 13, and can move away from the cable connector cover main body 13 until the surface of the flange portion 63 of the rotating shaft 61 on the cable takeout member 15 side (the surface on the left side in FIG. 12 ) abuts against the female thread portion 213 of the cable connector cover main body 13. As described above, the male thread portion 211 of the rotating shaft 61 has four threads and the female thread portion 213 of the cable takeout member through hole 41 has three threads, so the cable takeout member 15 can only rotate once.

[0035] The third embodiment also provides the same functions and effects as the first and second embodiments described above.

[0036] The present invention is not limited to the first and second embodiments. In the first embodiment, various cases are possible for the number and positions of the click recesses and click protrusions. For example, it is possible to provide the click recesses and click protrusions at every 30 degrees to enable the cable drawing direction to be fixed in 12 directions, or to provide the click recesses and click protrusions at every 45 degrees to enable the cable drawing direction to be fixed in 8 directions. In the second embodiment, the cable take-out member engaging recess and the cable take-out member fixing claw may be provided as a pair at opposing positions. In the second embodiment, various cross-sectional shapes of the cable connector cover and the cable take-out member are possible. For example, if the cross-sectional shapes of the cable connector cover and the cable take-out member are triangular, and there are three cable take-out member engaging recesses and two cable take-out member fixing claws, the cable can be taken out in three directions. In the first and third embodiments, a rotation shaft may be provided on the cable connector cover main body side. In the first embodiment, the click recess may be provided on the rotary shaft side, and the click protrusion may be provided on the rotary shaft engagement portion side. Additionally, the illustrated configuration is merely an example. [Industrial Applicability]
