[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] The present invention provides an embodiment of a remote control mechanism suitable for a straight plug connector, through which the remote control structure is used to realize the plugging and unplugging of the straight plug connector, such as Figures 1 to 17 As shown, hereinafter referred to as the institution.

[0069] The mechanism includes a hand-grip assembly for an operator to hold and a clamping assembly for clamping a plug or a socket. The hand-grip assembly and the clamping assembly are arranged as a whole through a connecting assembly. The length of the connecting assembly depends on the distance between the operator and the straight plug connector to be operated.

[0070] The hand-holding assembly includes a handle 1, a handle 2, a positioning key 3, a pressing shaft 4, a torsion spring 5, a first return spring 6, and a nut 7. The clamping assembly includes a gripper 9, a retraction rod 10, a retraction box 11, a second return spring 12, and a roller 13. The connecting assembly includes a support tube 14 whose two ends are respectively fixed to the handle 1 and the retraction box 11, and a steel wire rope 15 whose two ends are respectively connected to the handle 2 and the retraction rod 10.

[0071] The handle 1 is provided with a handle 2, a positioning key 3, a pressing shaft 4, a torsion spring 5, a first return spring 6, and a nut 7. The structure of the handle 1 is as follows: Fig.17 As shown, any cross section thereof is U-shaped, and the overall structure is a U-shaped groove structure. A support tube 14 is inserted into the U-shaped groove at one end of the handle 1, and the end of the support tube 14 is inserted into the U-shaped groove, and the corresponding rivets pass through the side wall of the handle 1 and the support tube 14, so that the support tube 14 is fixed on the handle 1. In this embodiment, the support tube 14 is vertically inserted into the handle 1.

[0072] The handle 1 is hinged to the end of the support tube 14 with the handle 2, and the hinged end of the handle 2 is nested in the U-shaped groove, and the third rivet 803 passes through the side wall of the handle 1 and the handle 2, wherein the hole at the end of the handle 2 is clearance-matched with the third rivet 803, so that the handle 2 can rotate around the third rivet 803. The other end of the handle 2 is arranged with locking teeth 201, and the arrangement direction of the locking teeth 201 is perpendicular to the length direction of the handle 2 (i.e., the rotation direction of the movable end of the handle). Fig.11 The figure shows a three-dimensional schematic diagram of the handle 2. Any cross section of the handle 2 is a U-shaped groove, and the whole is a U-shaped groove structure. The two side walls of one end of the handle 2 are provided with through holes for the third rivet 803 to pass through, and the end faces of the two side walls of the other end are evenly distributed with locking teeth 201.

[0073] A pressing shaft 4 is vertically provided at the end of the handle 1 away from the support tube 14. Figure 8 As shown, the pressing shaft 4 includes a pressing portion 401 for pressing, and a shaft portion 402 for passing through the handle 1, and the shaft portion 402 is vertically arranged on one side of the pressing portion 401. After the pressing shaft 4 is passed through the handle 1, the pressing portion 401 is engaged with one of the outer side walls of the handle 1, and the end of the shaft portion 402 away from the pressing portion 401 extends out of the other side wall of the handle 1. The end of the shaft portion 402 away from the pressing portion 401 is provided with a threaded connection section, and is threadedly connected to a nut 7. The nut 7 is engaged with the outer side wall of the handle 1 to limit the pressing shaft 4 on the handle 1.

[0074] A stop step 403 is provided at a position of the shaft portion 402 near the threaded connection section, and a first return spring 6 is sleeved between the stop step 403 and the threaded connection section. One end of the first return spring 6 abuts against the inner wall of the handle 1, and the other end abuts against the stop step 403. Under the elastic force of the first return spring 6, the nut 7 abuts against the outer wall of the handle 1, and the pressing portion 401 has a distance from the corresponding outer wall of the handle 1.

[0075] The outer wall of the shaft portion 402 near the pressing portion 401 is provided with a torsion spring groove 404 in an annular direction, and a torsion spring 5 is sleeved in the torsion spring groove 404, and the torsion spring 5 can be rotatably arranged in the torsion spring groove 404. The outer wall of the shaft portion 402 on both sides of the torsion spring groove 404 is provided with a retaining spring groove 405, and a retaining spring 18 is embedded in the retaining spring groove 405. The shaft portion 402 between the two retaining springs 18 is sleeved with a positioning key 3, and the positioning key 3 is axially limited on the shaft portion 402 by the two retaining springs 18, and the positioning key 3 is rotatably arranged on the shaft portion 402.

[0076] Position key 3 Figures 9 and 10 As shown, the positioning key 3 is provided with a through hole for penetrating the shaft 402, so that the positioning key 3 can be rotatably set on the shaft 402. The positioning key 3 is also provided with an avoidance groove 301 for avoiding the torsion spring 404, and the through hole on the positioning key 3 vertically passes through the avoidance groove 301. One of the torsion arms of the torsion spring 5 extends out of the avoidance groove 301 and abuts against the first stop structure in the handle 1. In this embodiment, the first stop structure adopts a first rivet 801 that is penetrated and fixed on the handle 1. The bottom of the avoidance groove 301 of the positioning key 3 is provided with a torsion arm hole 304 that passes through the positioning key 3, and the other torsion arm of the torsion spring 5 passes through the torsion arm hole 304. A positioning tip 303 is provided at one end of the positioning key 3, and a boss 302 is provided at one end of the positioning key 3 away from the positioning tip 303. The boss 302 is used to abut against a second stop structure limited in the handle 1. In this embodiment, the second stop structure adopts a second rivet 802 that is fixed on the handle 1, and the two rivets (the first rivet 801 abutted by the torsion arm and the second rivet 802 corresponding to the boss 302) have opposite circumferential stop directions for the torsion arm of the torsion spring 5 and the boss 302. The positioning key 3 is elastically rotated and limited in the inner cavity of the handle 1 through the torsion arm of the torsion spring 5 and the boss 302, so as to realize the circumferential positioning of the torsion spring 5 and the positioning key 3. When the torsion spring 5 is not subjected to force, the positioning tip 303 can be directed toward the other end of the handle 1 through the support of the torsion spring 5.

[0077] When the handle 2 is not locked on the handle 1, the end of the handle 2 where the locking tooth 201 is located is located on the outside of the handle 1. The side of the locking tooth 201 close to the positioning key 3 is relatively gentle, and the side away from the locking tooth 201 is relatively steep. When the handle 1 and the handle 2 are held by both hands at the same time and squeezed hard, the distance between the handle 1 and the handle 2 is reduced, and the locking tooth 201 rotates toward the positioning key 3. When the locking tooth 201 contacts the positioning key 3, the locking tooth 201 squeezes the positioning key 3, so that the positioning key 3 overcomes the elastic force of the torsion spring 5 and rotates to avoid the locking tooth 201. When the locking tooth 201 rotates to enable the positioning tip 303 of the positioning key 3 to be stuck in the tooth groove between two adjacent locking teeth 201, the torsion spring 5 forms a torque in the circumferential direction to reset the positioning key 3, so that the positioning key 3 can be kept between the tooth grooves. A plurality of locking teeth 201 are distributed on the handle 2, and the positioning tip 303 can be adjusted in the corresponding tooth groove according to the size of the clamped connector and the size of the clamping force to keep the handle 2 fixed. The positioning tip 303 has a certain width, and can clamp the locking teeth 201 on both side walls of the handle 2 at the same time, or, in other embodiments, the width of the positioning tip 303 can be reduced to only mesh with the locking teeth 201 on one side wall.

[0078] When the handle 2 and the positioning key 3 are unlocked, the pressing shaft 4 is pressed to drive the positioning key 3 to move axially, so that the positioning tip 303 is offset from the tooth groove of the locking tooth 201, and the positioning key 3 returns to its original position under the action of the torsion spring 5.

[0079] Two through holes are set near the middle position of the handle 2. After the ends of the wire rope 15 pass through the two through holes in turn, the crimping sleeve 19 is used to fix the ends of the wire rope 15 to the wire rope 15 itself, so that one end of the wire rope 15 is fixed to the handle 2. By holding the handle 2, the wire rope 15 can be pulled.

[0080] The end of the support tube 14 close to the hand-grip assembly and the end close to the clamping assembly are both provided with long holes, and the wire rope 15 is inserted into the support tube 14. The two ends of the wire rope 15 pass through the corresponding long holes at the two ends of the support tube 14 and are respectively connected to the handle 2 and the clamping assembly.

[0081] The clamping assembly includes a gripper 9, a retracting rod 10, a retracting box 11, a second return spring 12, and a roller 13. A fixing cylinder 1101 is provided on one side of the retracting box 11, and the end of the support tube 14 is inserted into the fixing cylinder 1101 and fixed by corresponding rivets.

[0082] Among the two opposite side surfaces perpendicular to the side surface where the fixing tube 1101 is located, one of the side surfaces is provided with a pair of fixing ears 1102, on which the corresponding fourth rivets 804 are pierced, and on which the roller 13 is rotatably arranged, a wire rope hole 1103 is provided on the wall of the shrinkage box 11 between the two fixing ears 1102; and the other side surface is provided with a gripper mounting hole 1104 connected to the inner cavity of the shrinkage box 11.

[0083] A pair of grippers 9 are symmetrically installed in the shrink box 11. Fig.14 , Fig.15 As shown, the gripper 9 includes a clamping portion 901, a hinge portion 902, and a push-pull portion 903. The gripper 9 is bent as a whole, and the hinge portion 902 is located at the bent position. The hinge portion 902 includes a gripper hinge hole I 904 that penetrates the gripper 9. The corresponding fifth rivet 805 is used to pass through the gripper hinge hole II 1105 on the shrink box 11 and the gripper hinge hole I 904 on the gripper 9, and the fifth rivet 805 is fixed on the shrink box 11. The gripper 9 is rotatably set on the fifth rivet 805 through the gripper hinge hole I 904. In order to make the gripper 9 open and close smoothly, the gripper hinge hole I 904 is a long hole, so that the gripper 9 can slide in the gripper hinge hole I 904.

[0084] The clamping fingers 901 of the two grippers 9 are arranged opposite to each other and extend out of the retracting box 11. After the opposite surfaces are pressed against the outer wall of the plug, the plug can be pulled out. The retracting rod 10 is arranged inside the retracting box 11. Fig.16 As shown, the retracting rod 10 includes a pin 1001 and a pull ear 1002 disposed on the side wall of the pin 1001, and the pull ear 1002 is located in the middle of the pin 1001. The push-pull portion 903 is disposed in the retracting box 11, and the push-pull portions 903 of the two grippers 9 are both provided with push-pull holes 905, the two push-pull holes 905 are aligned, and the two ends of the pin 1001 are inserted into the push-pull holes 905, and the pull ear 1002 is pulled to bring the clamping finger portions 902 of the two grippers 9 closer to each other.

[0085] The pull ear 1002 is provided with a through hole for passing the steel wire rope 15. The end of the steel wire rope 15 is passed through the steel wire rope hole 1103 and the through hole of the pull ear 1002 in sequence, and then passes through the steel wire rope hole 1103. The end of the steel wire rope 15 is crimped and fixed to the steel wire rope body using a crimping sleeve 19, so that the end of the steel wire rope 15 is fixed to the pull ear 1002. The steel wire rope 15 passes around the roller 13 to reduce the friction of the steel wire rope 15 when it changes direction at a corner.

[0086] A second return spring 12 is also provided in the shrink box 11. The second return spring 12 is sleeved on the wire rope 15, one end of which abuts against the push-pull part of the gripper 9, and the other end abuts against the inner wall of the shrink box 11. Under the pushing effect of the elastic force of the second return spring 12 on the push-pull part, the gripper 9 is in an open state.

[0087] When the steel wire rope 15 is pulled, the gripper 9 moves into the shrink box 11 (at this time, the fifth rivet 805 moves toward the clamping part 901 relative to the gripper hinge hole I904), the gripper 9 rotates around the fifth rivet 805, and the clamping parts 901 move closer to clamp the connector. When the steel wire rope 15 is released, under the action of the second return spring 12, the gripper 9 moves out of the shrink box 11, the fifth rivet 805 moves toward the push-pull part 903 relative to the gripper hinge hole I904, the gripper 9 rotates around the fifth rivet 805, and the clamping parts 901 move away from each other, and the connector is released.

[0088] Hold the handle 2, bring the handle 2 close to the handle 1, pull the wire rope 15, the wire rope 15 pulls the retractable rod 10, the retractable rod 10 pulls the push-pull part of the grip 9 backward, overcomes the elastic force of the second reset spring 12, and thus closes and tightens the grip 9; under the action of the first reset spring 6, the positioning key 3 is located on the rotation trajectory of the movable end of the handle 2, at this time the locking tooth 201 on the handle 2 cooperates with the positioning key 3 to lock the handle 2, so that the plug 16 can be clamped, the plug 16 can be unplugged from the socket 17, or the plug 16 can be plugged into the socket 17.

[0089] After the plug 16 is plugged in and out, the pressing part 401 of the pressing shaft 4 causes the shaft part 402 to overcome the elastic force of the first reset spring 6 and move toward one side of the handle 1, so that the positioning tip 303 of the positioning key 3 axially disengages from the tooth groove of the locking tooth 201. Under the elastic restoring force of the second reset spring 12, the wire rope 15 is pulled to disengage the handle 2 from the U-shaped groove of the handle 1. At the same time, the gripper 9 is opened, the pressing shaft 4 is released, and the pressing shaft 4 is restored to its original position under the restoring force of the first reset spring 6, thereby restoring the positioning key 3 to its original position, and the next remote operation can be continued.

[0090] In order to facilitate the clamping of the mechanism, a hexagonal platform 1601 is circumferentially arranged on the outer wall of the plug 16 , and the gripper 9 can be stably clamped on the hexagonal platform 1601 .

[0091] The dedicated remote control mechanism of the present invention can realize the remote plugging and unplugging of the connector, and realizes the function of connecting and unplugging the connector using the remote control mechanism. By holding the handle 2 tightly, the gripper 9 can clamp the hexagonal platform 1601 of the plug 16, such as Fig.18 As shown, at this time, the locking teeth 201 are automatically locked on the positioning key 3 to keep the plug 16 clamped. The plug 16 can rotate and move up and down with the remote control mechanism to achieve the plug and unplug of the plug 16 and the socket 17. Press the pressing shaft 4, the locking teeth 201 are loosened from the positioning key 3, the handle 2 is automatically loosened, and the remote control mechanism can be removed from the plug 16.

[0092] In other embodiments, the steel wire rope 15 may be replaced by a draw rope made of other materials, such as a draw rope made of plastic.

[0093] In other embodiments, the respectable wire rope 15 is directly connected to the push-pull portion 903 of the gripper 9.

[0094] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
