[0003] In the existing solution, when the separable connector is installed and separated from the bushing on the switch device, it is necessary to manually screw the separable connector onto the bushing, which is extremely inconvenient to operate and has low installation and removal efficiency. Moreover, sometimes when the separable connector and the bushing are inspected and repaired, it is not necessary to inspect all parts, while the existing solution requires the disassembly of each part of the separable connector when the separable connector and the bushing are separated, which greatly increases the workload and affects the work efficiency. In addition, since the existing solution is to manually disconnect and separate the separable connector and the bushing, there is a safety hazard when a power failure occurs. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0019] See also Figure 1-3The utility model provides a pluggable detachable connector with an automatic disconnection function, comprising: a connector body 10, a connecting assembly 20, a driving assembly 30 and a shielding assembly 40; the connector body 10 comprises a communicating transverse cavity 11 and a longitudinal cavity 12, the connecting assembly 20 and the driving assembly 30 are both arranged in the transverse cavity 11, one end of the connecting assembly 20 is provided with a threaded structure for connecting to a conductor 51 of a sleeve 50, and the other end is rotatably connected to a driving end of the driving assembly 30, so as to drive the connecting assembly 20 to move transversely by the driving assembly 30, so as to realize the disconnection or connection between the detachable connector and the sleeve 50; a shielding assembly 40 is provided on the outer side of the connection between the connecting assembly 20 and the driving assembly 30, and the shielding assembly 40 is connected to the grounding terminal.

[0020] In this embodiment, when it is necessary to disconnect the detachable connector and the sleeve 50, or to connect the detachable connector and the sleeve 50, the detachable connector and the sleeve 50 can be automatically disconnected or connected by controlling the operation of the drive assembly 30, without requiring excessive human intervention, thereby greatly improving the efficiency of installing or disassembling the detachable connector and the sleeve 50, and greatly reducing the safety hazard of electric shock to the operator.

[0021] In addition, when inspecting and checking the detachable connector or the sleeve 50, the traditional solution needs to open the cover at the rear end of the detachable connector when disassembling or installing the detachable connector and the sleeve 50, and then disconnect or connect through manual operation. However, when the rear end cover is opened, some parts that are sealed and fixed by the back cover will be scattered, which is inconvenient for installation and disassembly, especially when it is not necessary to inspect each component, such operation greatly reduces the efficiency of inspection and maintenance. In this solution, when disconnecting the detachable connector and the sleeve 50, it is not necessary to open the cover, and the connection component 20 can be separated from the sleeve 50 conductor by controlling the operation of the drive component 30, so that the detachable connector and the sleeve 50 can be separated as a whole by plugging and unplugging, thereby achieving rapid inspection and greatly improving work efficiency.

[0022] For the connecting component 20, in one embodiment, the connecting component 20 may include a connecting rod 21, a first shielding net 22 and a fixing member 23; the fixing member 23 is a barrel-shaped structure with an opening on one bottom surface, and the first shielding net 22 is fixedly arranged on the side and bottom surfaces inside the fixing member 23. One end of the connecting rod 21 is provided with an external thread for matching and connecting with the internal thread inside the conductor 51 of the sleeve 50. The other end of the connecting rod 21 extends into the first shielding net 22 and is fixedly connected to the bottom end of the first shielding net 22.

[0023] In this embodiment, the connecting rod 21 can be a bolt with an external thread at one end, which is used to cooperate with the internal thread inside the conductor 51 of the sleeve 50 to achieve the connection between the sleeve 50 and the detachable connector. The other end of the connecting rod 21 is fixed inside the fixing member 23, wherein the connecting rod 21 and the fixing member 23 are shielded and isolated by the first shielding net 22 to avoid partial discharge.

[0024] The connecting rod 21 can be driven to rotate by a driving motor 31. In order to enable the driving motor 31 to move in the transverse cavity 11 and thereby realize the transverse movement of the connecting rod 21, in one embodiment, the driving assembly 30 may include a driving motor 31 and at least two sets of slide rails 32; at least two sets of slide rails 32 are fixedly arranged on the inner surface of the transverse cavity 11 and are arranged in the transverse direction; the driving motor 31 is slidably arranged on each slide rail 32, and the driving end of the driving motor 31 is fixedly connected to the outer bottom surface of the fixing member 23, so as to drive the fixing member 23 to rotate, so as to realize the separation and connection of the connecting rod 21 and the catheter conductor 51.

[0025] In this embodiment, multiple groups of slide rails 32 can be set, for example, four groups can be set, which are respectively set in the upper, lower, left and right directions of the drive motor 31 to ensure the reliability of the lateral sliding of the drive motor 31 and improve the stability of the drive motor 31.

[0026] In addition, in order to further ensure that the drive motor 31 can continue to slide laterally after the external thread of the connecting rod 21 and the internal thread of the conductor 51 of the sleeve 50 are disengaged, in one embodiment, the drive motor 31 can be a double-shaft motor, the first shaft 311 is fixedly connected to the outer bottom surface of the fixing member 23, and the second shaft 312 is facing the tail end direction of the transverse cavity 11; an auxiliary drive plate 60 is also fixedly arranged at a position near the tail end in the transverse cavity 11, and the surface of the auxiliary drive plate 60 is perpendicular to the drive shaft of the drive motor 31; a through hole is opened on the auxiliary drive plate 60 at a position opposite to the second shaft 312, the through hole is provided with an internal thread, and the second shaft 312 is provided with an external thread, which is used to continue to drive the drive motor 31 to move through the cooperation of the internal thread of the through hole and the external thread of the second shaft 312 after the connecting rod 21 is separated from the conductor of the sleeve 50. In this way, when the detachable connector and the sleeve 50 are disconnected, after the external thread of the connecting rod 21 and the internal thread of the conductor 51 of the sleeve 50 are disengaged, the external thread of the second output shaft 312 of the drive motor 31 can be matched and connected with the internal thread on the auxiliary drive plate 60, so that the drive motor 31 can continue to move backward, and the connection rod 21 and the copper terminal 13 in the longitudinal cavity 12 can be separated. Similarly, when the detachable connector and the sleeve 50 are connected, the first output shaft 311 and the drive motor 31 can be transported forward by the external thread of the second output shaft 312 of the drive motor 31 and the internal thread on the auxiliary drive plate 60, so that the external thread of the first output shaft 311 and the internal thread of the conductor 51 of the sleeve 50 can be matched, thereby realizing the connection between the sleeve 50 and the detachable connector. The drive motor 31 can be powered by a battery or connected to an external power supply, and the drive motor 31 can also be wirelessly controlled by a communication module, a control module, etc.

[0027] Of course, it should be noted that in order to ensure the reliability of the drive motor 31 driving the connecting rod 21 to connect the sleeve 50 and the detachable connector, the installation position of the auxiliary drive plate 60 should meet the following conditions: when the connecting rod 21 is separated from the sleeve 50 conductor, the external thread of the second output shaft 312 has been matched with the internal thread of the through hole. This avoids the situation that when the connecting rod 21 is separated from the sleeve 50 conductor, the second output shaft 312 is still not matched with the internal thread on the auxiliary drive plate 60, causing the drive motor 31 to be unable to continue sliding to separate the connecting rod 21 from the copper terminal 13; it also avoids the situation that when the sleeve 50 and the detachable connector are connected, the drive motor 31 cannot move forward, the first output shaft 311 cannot be threadedly matched with the sleeve 50 conductor 51, and the detachable connector and the sleeve 50 cannot be connected.

[0028] Furthermore, a groove can be provided on the end face of the second output shaft 312, and the groove can cooperate with a convex wrench. In this way, when the internal drive fails, or in some special circumstances, such as when the drive motor 31 is not working, the operator can insert the convex wrench into the groove, and then turn the wrench to rotate the shaft of the drive motor 31, thereby driving the connecting rod 21 to rotate, thereby realizing the connection or separation of the sleeve 50 and the detachable connector.

[0029] In one embodiment, the connecting rod 21 is provided with a gap groove 211 at the center position of the external threaded portion, so that the front end of the connecting rod 21 has a certain elasticity, thereby making it easier to screw into the internal thread of the conductor 51 of the sleeve 50, and can reduce the wear of the connecting rod 21 and increase the service life of the connecting rod 21.

[0030] In addition, in order to further improve the shielding effect and reduce the safety hazards of operators, in one embodiment, the shielding assembly 40 may include a second shielding net 41, which is sleeved on the outside of the connecting assembly 20 and the driving assembly 30, and the second shielding net 41 is connected to the grounding connection terminal 14 located on one side of the longitudinal cavity 12.

[0031] The modules or units in the device of the embodiment of the utility model can be combined, divided and deleted according to actual needs. The above disclosure is only the preferred embodiment of the utility model, and of course it cannot be used to limit the scope of the rights of the utility model. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments are implemented, and equivalent changes made according to the claims of the utility model still fall within the scope of the utility model.
