In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0029] In this embodiment, if Figures 1 to 3 As shown, the on-off device is used to energize or de-energize the transmission line and the lead wire 17. The on-off device includes: a box body and a conductive member. The transmission line is arranged in the box body. The conductive member 16 is arranged in the box body and is electrically connected to the lead wire 17. The conductive member 16 is lifted and lowered to have a conductive position in contact with the transmission line and conductively connected thereto and a de-energizing position separated from the transmission line.

[0030] In this way, the drop wire 17 can be electrically connected or disconnected with the transmission line by controlling the lifting of the conductive member 16. When it is necessary to deal with the problem that the metal part of the live conductive wire is completely exposed in the meter box, the operator can control the conductive member 16 to rise on the ground so that the conductive member 16 is in the conductive position, so that the drop wire 17 is electrically connected with the transmission line, which is convenient for power transmission through the drop wire 17. After the problem is solved, the operator can control the conductive member 16 to fall on the ground so that the conductive member 16 is in the power-off position, so that the drop wire 17 is electrically disconnected from the transmission line. In this way, by controlling the lifting of the conductive member 16, the drop wire 17 can be electrically connected or disconnected with the transmission line, avoiding the need for the operator to climb a high ladder to operate in the related art, making the power on and off operation of the drop wire and the transmission line simple. Therefore, the technical solution of this embodiment effectively solves the problem that the power on and off operation of the drop wire and the transmission line in the related art is relatively complicated. In addition, in this embodiment, the setting of the box body can reduce the possibility of mice gnawing at the electrical connection between the transmission line and the conductive member, and improve the reliability of power transmission.

[0031] like Figures 1 to 3 As shown, the box body includes an upper box body 2 and a lower box body 1 arranged below the upper box body 2. The upper box body 2 is provided with a first notch, and the lower box body 1 is provided with a second notch. When the upper box body 2 and the lower box body 1 are buckled together, the first notch and the second notch form a through hole, and the transmission line is passed through the through hole. The structure of the upper box body 2 and the lower box body 1 is simple and easy to process. The provision of the first notch and the second notch facilitates the installation and removal of the transmission line.

[0032] like Figures 1 to 3 As shown, the on-off device further includes a sealing ring 3 disposed between the side wall of the via hole and the transmission line. The provision of the sealing ring 3 reduces the possibility of rainwater or mice entering the box body, thereby improving the reliability of the electrical connection between the transmission line and the conductive member.

[0033] like Figures 1 to 4 As shown, a plug-in block 9 is provided on the inner side wall of the upper box body 2, and a plug-in seat 4 is provided on the inner side wall of the lower box body 1. A slot is provided on the plug-in seat 4, and a plug-in block 8 can be floatingly provided on the plug-in block 9, and the plug-in block 8 floats to have a connection position extending into the slot and a separation position detached from the slot. In this way, when the upper box body 2 and the lower box body 1 are buckled, the plug-in block 8 can float to extend into the slot to fix the upper box body 2 and the lower box body 1. When the upper box body 2 and the lower box body 1 need to be separated, the operator holds the upper box body 2 and the lower box body 1 and applies a reverse force to the upper box body 2 and the lower box body 1, so that the plug-in block 8 can float and detach from the slot under the action of an external force, so that the upper box body 2 can be separated from the lower box body 1. The structure of the slot and the plug-in block 8 is simple and easy to process.

[0034] like Figures 1 to 4As shown, the plug-in block 9 is provided with a connecting block 5, an elastic member 6 telescopically connected to the connecting block 5, and a limit plate 7 arranged at the end of the elastic member 6. The plug-in block 8 is connected to the surface of the limit plate 7 facing away from the elastic member 6. The setting of the elastic member 6 can continuously apply elastic force to the plug-in block 8, so that the plug-in block 8 can remain in the connection position located in the slot when no external force is applied. The diameter of the limit plate 7 is larger than the diameter of the slot to cooperate with the slot stopper. The setting of the limit plate 7 can cooperate with the slot limit to reduce the possibility of the elastic member 6 extending into the slot, so that the cooperation between the plug-in block 8 and the slot is more reliable.

[0035] like Figures 1 to 4 As shown, the surface of the plug block 8 facing the slot is a first arc surface, and the surface of the slot facing the plug block 8 is a second arc surface. The first arc surface and the second arc surface are provided to facilitate the switching of the plug block 8 between the connection position and the separation position. There are two plug blocks 8, and the two plug blocks 8 are respectively provided at the two ends of the elastic member 6. There are two slots, and the two slots are respectively provided on the two opposite inner side walls of the socket 4. The provision of two plug blocks 8 and two slots makes the connection between the upper box body 2 and the lower box body 1 more reliable when the two plug blocks 8 are in the connection position.

[0036] In other embodiments, the surface of the plug block 8 facing the slot is a first arcuate surface, and the surface of the slot facing the plug block 8 is a second arcuate surface. Alternatively, there are two plug blocks 8, which are respectively arranged at both ends of the elastic member 6; there are two slots, which are respectively arranged on two opposite inner side walls of the socket 4.

[0037] like Figures 1 to 3 As shown, the power on / off device also includes a driving motor 11, a screw 12 connected to the output end of the driving motor 11, and an insulating sleeve 13 sleeved on the screw 12. The insulating sleeve 13 is provided with a threaded hole that can cooperate with the screw 12, and the insulating sleeve 13 is connected below the conductive member 16. The driving motor 11 drives the screw 12 to rotate to drive the insulating sleeve 13 and the conductive member 16 to rise and fall. The driving motor 11, the screw 12 and the insulating sleeve 13 have a simple structure and are easy to process. The operator can control the rotation direction of the driving motor 11 on the ground to make the conductive member 16 rise or fall, which improves the safety of the operator at work and reduces the intensity of the work. The driving motor 11 rotates to drive the screw 12 to rotate, so that the insulating sleeve 13 threadedly matched with the screw 12 moves up and down, thereby driving the conductive member 16 to move up and down.

[0038] like Figures 1 to 3As shown, a guide hole is provided on the bottom wall of the lower box body 1, and the insulating sleeve 13 is movably inserted into the guide hole. The cross section of the insulating sleeve 13 perpendicular to its moving direction is a polygon, and the guide hole is a polygonal hole. The insulating sleeve 13 is guided and matched with the guide hole. The cross section of the insulating sleeve 13 is set to be a polygon, and the guide hole is a polygonal hole, so that when the insulating sleeve 13 moves up and down, the insulating sleeve 13 can be guided and matched with the guide hole to reduce the swing of the insulating sleeve 13 when it moves up and down, so that the lifting and lowering of the conductive member 16 is more stable, so that the electrical connection between the lead-in wire and the transmission line is more reliable.

[0039] like Figures 1 to 3 As shown, the on-off device also includes a control member and a detection member, and the detection member is connected to the control member by signal. The detection member can detect the position of the conductive member 16, and the control member is connected to the drive motor 11. In this way, the detection member can detect whether there is a gap between the conductive member 16 and the transmission line, so that when the conductive member 16 is in the conductive position, the electrical connection between the lead-in wire and the transmission line is more reliable. In this embodiment, the detection member is an in-place detection member, and the in-place detection member can detect the gap between the transmission line and the conductive member 16. When the in-place detection member detects that there is a gap between the transmission line and the conductive member 16, the controller controls the drive motor 11 to continue driving, so that the conductive member 16 continues to rise and contacts with the transmission line to be electrically connected.

[0040] In this embodiment, the controller can be connected to the Internet of Things and controlled by an external mobile terminal, such as a mobile phone or a tablet. The status of whether the conductive member 16 is in the conductive position or the power-off position and whether the connection between the conductive member 16 and the transmission line is heated can be sent to the mobile terminal in a timely manner, and an alarm prompt can be sent to the operator in real time.

[0041] like Figures 1 to 3As shown, the box body includes an upper box body 2 and a lower box body 1 arranged below the upper box body 2, and the power-on / off device also includes an installation box 10 arranged below the lower box body 1 and connected to the lower box body 1. The drive motor 11, the screw rod 12 and the insulating sleeve 13 are arranged in the installation box 10, and the insulating sleeve 13 can be lifted and lowered through the lower box body 1 and connected to the conductive member 16. The installation of the installation box 10 facilitates the installation of the drive motor 11, the screw rod 12 and the insulating sleeve 13, and can protect the drive motor 11, the screw rod 12 and the insulating sleeve 13. The lower end of the insulating sleeve 13 is provided with an outer flange 14, and a limiting column 15 is provided on the outer flange 14. The limiting column 15 extends upward, and when the limiting column 15 is limitedly matched with the bottom wall of the lower box body 1, the conductive member 16 is in a conductive position. The setting of the outer flange 14 facilitates the assembly of the limiting column 15. The setting of the limit column 15 can limit the rising range of the insulating sleeve 13, thereby limiting the rising range of the conductive member 16, avoiding the possibility of lifting the transmission line above the conductive member 16 when the conductive member 16 rises to a high height, thereby increasing the service life of the transmission line.

[0042] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
