DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0030] As shown in Figures 1 to 4 the present embodiment provides a cable access device, the cable access device comprising a mounting seat 100, a power supply joint 200 and an insulating sleeve 300, the power supply joint 200 being arranged on the mounting seat 100 in a transverse direction, the power supply joint 200 being electrically connected with the mounting seat 100, the insulating sleeve 300 being hingedly connected with the mounting seat 100, the insulating sleeve 300 having a protection groove 311 capable of accommodating the power supply joint 200, the insulating sleeve 300 having a protection position and a working position, when the insulating sleeve 300 is in the protection position, the power supply joint 200 is located in the protection groove 311, when the insulating sleeve 300 is in the working position, the power supply joint 200 is out of the protection groove 311.

[0031] The mounting seat 100 is used to connect a high-voltage pole, and the mounting seat 100 is fixed on the high-voltage pole by a connecting member such as a screw, so as to fix the entire cable access device on the high-voltage pole for use. When the cable access device of the present embodiment is not used for power supply, the insulating sleeve 300 is switched to the protection position, so that the power supply joint 200 is located in the protection groove 311, thereby avoiding exposure of the power supply joint 200 and reducing the risk of electric shock. When the cable access device of the present embodiment is used for power supply, the insulating sleeve 300 is switched to the working position, so that the power supply joint 200 is out of the protection groove 311, and the construction personnel can directly connect the power supply joint of the power supply equipment to the power supply joint 200, so as to quickly conduct with the high-voltage pole, the entire connection operation process is convenient and fast, the operation convenience of the cable access device is improved, and the insulating sleeve 300 has an insulating effect, so that the operation process is safer.

[0032] Specifically, the cable access device is installed at both ends of the cable line section requiring construction, after the power supply device accesses the cable access device, the current of the original circuit of the maintenance cable line section requiring construction is introduced through the bypass power supply line formed by the power supply device and the two cable access devices, the current does not flow through the maintenance cable line section, the construction personnel can perform construction on the cable line section between the two cable access devices, and during the maintenance construction, the current flows through the bypass power supply line to supply power to the user end of the nearby residents, thereby reducing the influence of the construction process on the residents.

[0033] As shown in Figure 1 , in the embodiment, the power supply joint 200 extends in the front-rear direction, and the mounting seat 100 extends in the up-down direction.

[0034] As shown in Figures 1 to 4 , the cable access device further comprises a locking member, which is arranged between the insulating sleeve 300 and the mounting seat 100, and can lock and connect the insulating sleeve 300 and the mounting seat 100 when the insulating sleeve 300 is in the working position. When the insulating sleeve 300 is in the working position, the construction personnel can lock the insulating sleeve 300 and the mounting seat 100 through the locking member, so as to avoid the insulating sleeve 300 from retreating to the protection position during the process of accessing the power supply joint, avoid the insulating sleeve 300 from hindering the construction personnel from accessing the power supply joint, and ensure the smooth progress of the power-on process.

[0035] As shown in Figures 1 to 4 , the locking member comprises a magnetic member arranged on the insulating sleeve 300, and the magnetic member is in magnetic attraction cooperation with the mounting seat 100 when the insulating sleeve 300 is in the working position and abuts against the mounting seat 100. When the insulating sleeve 300 is in the working position and abuts against the mounting seat 100, the magnetic member is in magnetic attraction cooperation with the mounting seat 100 to lock the insulating sleeve 300 and the mounting seat 100, without the need for other locking operations, so as to simplify the operation process, improve the power-on efficiency, and improve the user experience.

[0036] As shown in Figure 5 and Figure 6 , the protection groove 311 is provided with a mounting groove 312, a plurality of clamping hooks 313 are arranged at the mounting groove 312, and the magnetic member is arranged in the mounting groove 312 and clamped with the clamping hooks 313. When the insulating sleeve 300 is in the working position, the hook head of the clamping hook 313 abuts against the lower surface of the magnetic member, so as to avoid the magnetic member from being taken out of the mounting groove 312 downward. When the magnetic member is damaged or fails, the construction personnel can directly take out the magnetic member from the mounting groove 312 for replacement, so as to facilitate the construction personnel to replace the magnetic member and ensure the overall performance of the cable access device.

[0037] In the embodiment, the opening direction of the mounting groove 312 is consistent with the opening structure of the protection groove 311.

[0038] In the embodiment, when the insulating sleeve 300 is in the working position, the installation groove 312 is arranged corresponding to the end surface of the magnetic attraction rod 110 away from the installation base 100, so as to ensure the magnetic attraction area between the magnetic attraction member and the magnetic attraction rod 110, thereby ensuring the stability of the magnetic attraction between the magnetic attraction member and the magnetic attraction rod 110.

[0039] Specifically, the plurality of clamping hooks 313 are arranged equidistantly in the circumferential direction of the installation groove, and the clamping hook 313 is an arc-shaped block extending in the circumferential direction of the installation groove. A guide slope is arranged on the hook head of each clamping hook 313. In the direction in which the insulating sleeve 300 rotates from the working position to the protection position, the distance between the guide slopes of the opposite two clamping hooks gradually decreases, facilitating the installation of the magnetic attraction member. The construction personnel pushes the magnetic attraction member in the direction of the installation groove 312, so that the magnetic attraction member presses the clamping hook, the clamping hook deforms, and the magnetic attraction member can smoothly enter the installation groove 312.

[0040] In the embodiment, the clamping hook 313 is provided with two, and the two clamping hooks 313 are symmetrically arranged on the front and rear sides of the installation groove 312.

[0041] As shown in Figure 1 The insulating sleeve 300 includes a connecting base 330, a movable piece 320, and a protective sleeve 310. The connecting base 330 is arranged on the installation base 100. The middle part of the movable piece 320 is hingedly connected with the connecting base 330. The hinge shaft of the movable piece 320 and the connecting base 330 is perpendicular to the extension direction of the power supply connector 200. The protective sleeve 310 is connected with one end of the movable piece 320. The protection groove 311 is arranged on the protective sleeve 310. The other end of the movable piece 320 is provided with an operation part 340. The operation part 340 is pulled to drive the insulating sleeve 300 to rotate between the protection position and the working position, and the power supply connector 200 enters and exits the protection groove 311. The construction personnel uses the insulating operating rod to pull the operation part 340 to make the movable piece 320 rotate, and the power supply connector 200 enters and exits the protection groove 311. During the operation process, the construction personnel does not need to touch the power supply connector 200 and the installation base 100 by hand.

[0042] Specifically, when the movable piece 320 rotates to the position where the protective sleeve 310 abuts against the installation base 100, the magnetic attraction member can be connected and fixed with the installation base 100 under the magnetic attraction, thereby avoiding the reverse rotation of the movable piece 320, and ensuring the smooth progress of the power connection process.

[0043] As shown in Figures 1 to 4As shown, the mounting base 100 comprises a base body 120 and a magnetic rod 110, the power supply connector 200 is arranged on the base body 120 in a transverse direction, the insulating sleeve 300 is hingedly connected with the base body 120, the magnetic rod 110 is arranged on the side of the base body 120 close to the power supply connector 200, the magnetic rod 110 extends in the same direction as the power supply connector 200, when the insulating sleeve 300 is in the working position, the insulating sleeve 300 abuts against the magnetic rod 110, and the magnetic member is magnetically attracted to the magnetic rod 110. When the operator applies torque to the operating part 340 to rotate the insulating sleeve 300 to the working position, the sheath 310 can quickly contact the magnetic rod 110, which can reduce the angle of rotation of the movable part 320, and avoid that the rotation angle of the operating part 340 is too large to affect the clamping operation of the power supply connector.

[0044] As shown in the figure, Figure 4 The magnetic rod 110 is arranged in the mounting base 100 and is threadedly connected with the mounting base 100. Specifically, one end of the magnetic rod 110 towards the mounting base 100 is provided with a second threaded segment 111, and the mounting base 100 is provided with a threaded hole, the second threaded segment 111 is arranged in the threaded hole of the mounting base 100 and threadedly cooperates with the threaded hole. The operator can adjust the length of the magnetic rod 110 on the side of the mounting base 100 towards the power supply connector 200 according to the actual use, so as to adjust the size of the included angle between the hinged point between the movable part 320 and the insulating connector 330 and the straight line formed by the center of the front end face of the magnetic rod 110 and the vertical plane, so as to meet different construction requirements.

[0045] In this embodiment, the hinged point between the movable part 320 and the insulating connector 330 and the front end face of the magnetic rod 110 are in the same vertical plane, when the operator rotates the operating part 340 by 90°, the sheath 310 can abut against the magnetic rod 110, at this time, the operating part 340 is located directly below the hinged point, so as to avoid the power connection operation between the power supply connector and the power supply connector 200.

[0046] It should be noted that the middle part of the movable part 320 refers to the part of the movable part 320 except the two ends in the extension direction thereof.

[0047] In this embodiment, as shown in the figure, Figures 1 to 4In the front-rear direction, the front end surface of the magnetic attraction rod 110 is located at the rear side of the hinge point between the movable part 320 and the connecting seat 330, and the end surface of the magnetic attraction rod facing away from the seat body is arranged at an angle with the vertical line from the hinge shaft of the movable part and the seat body to the vertical surface (perpendicular to the front-rear direction and the left-right direction), and the angle is less than or equal to 10°. During the rotation of the insulating sleeve 300 from the protection position to the working position, the rotation angle of the insulating sleeve 300 does not exceed 100°, so that when the insulating sleeve 300 is in the working position, the horizontal distance of the operating part 340 protruding forward beyond the hinge point is small, which does not affect the power connection operation between the power supply joint and the power supply joint 200, and can also avoid the case that the movable part 320 is reversed when the magnetism fails, further ensuring the smooth progress of the power connection process.

[0048] As shown in Figure 1 When the insulating sleeve 300 is in the protection position, the opening of the protection groove 311 faces downward, the power supply joint 200 is located in the protection groove 311, the left side, the right side, the front side and the upper side of the power supply joint 200 are shielded by the sheath 310, and the operating part 340 is located on the side of the sheath 310 facing the mounting seat 100. Pull down the operating part 340 to make the movable part 320 rotate, and the power supply joint 200 is out of the protection groove 311, and the sheath 310 is rotated upward to abut against the mounting seat 100. At this time, the operating part 340 is located below the sheath 310, and the power supply joint 200 is exposed, and the operating part 340 is located behind the sheath 310.

[0049] As shown in Figure 1 The connecting seat 330 has an avoiding groove 331, which penetrates through both sides of the connecting seat 330 in the extension direction of the hinge shaft of the movable part 320 and the connecting seat 330. When the insulating sleeve 300 is in the protection position, the operating part 340 is located in the avoiding groove 331 and protrudes downward from the avoiding groove 331, and when the insulating sleeve 300 is in the working position, the operating part 340 is out of the avoiding groove 331. The structure of the insulating sleeve 300 is more compact, the setting of the connecting seat 330 will not interfere with the rotation of the operating part 340, and it is more conducive to the construction personnel to pull the operating part 340, and improves the convenience of the construction personnel operation. Specifically, the avoiding groove 331 is located at the rear side of the hinge point between the movable part 320 and the insulating connecting seat 330. When the insulating sleeve 300 is in the protection position, the construction personnel can directly contact the operating part 340 from the left side and the right side of the operating part 340 through the avoiding groove 331 and pull the operating part 340 to rotate.

[0050] In other embodiments, the operating part 340 adopts a rod-shaped structure.

[0051] As shown in Figure 1As shown, in the embodiment, the operation part 340 adopts a ring structure, facilitating the construction personnel to drive the operation part 340 to rotate by using an insulating tool or directly by hand, and in the process of rotation, the operation part 340 is not easy to slip off the hand of the construction personnel.

[0052] As shown in the drawings, Figure 1 As shown, the insulating sleeve 300 further comprises a reinforcing member 350 arranged between the movable member 320 and the sheath 310, the reinforcing member 350 has a first connecting surface and a second connecting surface, the first connecting surface is consistent with the extending direction of the sheath 310, the first connecting surface is connected with the sheath 310, and the second connecting surface is perpendicular to the first connecting surface, and the second connecting surface is connected with the movable member 320. The reinforcing member 350 can increase the connecting area between the movable member 320 and the sheath 310, thereby improving the connecting strength between the movable member 320 and the sheath 310, reducing the fracture between the movable member 320 and the sheath 310, and improving the service life of the cable access device.

[0053] As shown in the drawings, Figure 1 As shown, the reinforcing member 350 is provided with a weight-reducing groove 351, and the weight-reducing groove 351 is arranged to open away from the sheath 310. The weight-reducing groove 351 reduces the weight of the reinforcing member 350, and does not affect the improvement of the connecting strength between the sheath 310 and the movable member 320, thereby reducing the burden of the overhead line cable quick access device on the high-voltage electric pole.

[0054] In the embodiment, the edges of the weight-reducing groove 351 of the reinforcing member 350 are arc-structured, which can avoid the situation that the construction personnel is cut by the edges of the reinforcing member 350 in the process of construction, thereby further improving the safety of construction.

When the cable access device of the embodiment is used to supply power, the insulating sleeve 300 is switched to the working position, so that the conductive column is out of the protection groove 311, and the construction personnel can directly clamp the power supply device power supply connector on the conductive column, thereby realizing quick power connection.

[0058] In the embodiment, the conductive column and the mounting base 100 are made of conductive materials such as metal, and the insulating sleeve 300 is made of insulating materials such as plastic.

[0059] Specifically, in the embodiment, the protection groove 311 is matched with the shape of the conductive column.

[0060] In the embodiment, the outer surface of the conductive column is provided with a mesh anti-skid pattern which is wrapped around the outer periphery of the conductive column, so as to increase the friction between the conductive column and the power supply connector, thereby improving the stability of the connection between the power supply connector and the conductive column and improving the power supply stability.

[0061] In the embodiment, the front end of the conductive column is provided with a stopper which has a diameter larger than that of the conductive column, so as to prevent the power supply connector from slipping forward and separating from the conductive column, thereby further ensuring the stability of the power supply.

[0064] As shown, Figure 6 the cable access device further includes a fixing structure which is arranged below the conductive column and is connected with the operation part 340, and is used for fixing the downwardly extending cable line of the power supply device power supply connector, so as to avoid the shaking of the cable line and avoid affecting the connection between the power supply connector and the conductive column.
