Description

Technical Field

[0001] The utility model relates to a power taking device, in particular to a plug with an electric signal conversion function. Background Art

[0002] In order to achieve real-time monitoring and management of switchgear equipment such as narrow cabinets, sensors with built-in capacitor core rods are usually installed in the switchgear. The capacitor core rod can collect high-voltage current and convert it into an electrical signal and transmit the electrical signal to the live display, so that the operation and maintenance personnel can track and fully understand the operating status of the switchgear equipment in real time, thereby ensuring the safety of power supply. However, with the changes in market demand, the development of switchgear is becoming more and more miniaturized, and with the miniaturization of switchgear, the internal space can no longer accommodate sensors.

[0003] With the cancellation of sensors, in order to ensure that the live display can still receive electrical signals, the common practice on the market is to install a shielding net in the switch cabinet to replace the sensor. However, the main function of the shielding net is to prevent electromagnetic interference, and supplying power to the live display is not its main function. In addition, the change in the distance between the shielding net and the connecting copper busbar will affect the shielding net's collection of electrical signals. Therefore, higher requirements are placed on the accuracy of the installation position of the shielding net in the switch cabinet. If the shielding net is not installed accurately, the live display will not be able to accurately reflect the operating status of the switch cabinet equipment.

[0004] A plug is usually installed in the switch cabinet. The plug is often used to block and seal the copper busbar to prevent the copper busbar from discharging to the cabinet. The plug usually includes a shell made of insulating material. One end of the shell is provided with a sleeve that is completely sleeved on the copper busbar in the switch cabinet. The sleeve is connected to the copper busbar and isolated through the insulating shell to prevent the copper busbar from discharging to the cabinet. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a plug with an electrical signal conversion function which can convert high voltage current into an electrical signal.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a plug with an electrical signal conversion function, comprising a shell, one end of the shell is provided with a groove, a conductive connecting tube is arranged in the groove, the other end of the shell is provided with a conductive connecting part, an electrical signal converter capable of converting a large current into an electrical signal is arranged in the shell, and the two ends of the electrical signal converter are electrically connected to the conductive connecting tube and the conductive connecting part respectively.

[0007] The beneficial effect of the utility model is that the above scheme enables the plug to have the function of collecting electrical signals on the basis of the original function of blocking and sealing the connecting copper busbar. The plug which occupies a small space can be adapted to the increasingly miniaturized switch cabinets. The scheme will not increase excessive costs and the connection and fixing method between the plug and the connecting copper busbar is also very convenient, which also ensures that the electrical signal can be stably transmitted to the live display to reflect the operating status of the switch cabinet.

[0008] Furthermore, the electrical signal converter is a capacitor core rod.

[0009] The function of the capacitor core rod is to divide the high voltage on the charged body, that is, the copper bar, and take out a part of the low voltage to provide it to the charged display installed on the instrument door through the conductive connection part. The capacitor core rod is a common electrical component with many specifications and models, which is easy to select and low in cost.

[0010] Furthermore, a placement hole adapted to the electrical signal converter is provided in the shell, and locking holes are provided at both ends of the placement hole, and the aperture of the locking hole is smaller than the aperture of the placement hole.

[0011] The electrical signal converter is fixed inside the shell by providing a placement hole and a locking hole with a smaller diameter than the placement hole to prevent the electrical signal converter from moving inside the shell and thus breaking away from the connection with the conductive connecting part or the conductive connecting cylinder.

[0012] Furthermore, the conductive connection part is a conductive fastener and the fastener is used to fix a connection line connected to a powered display. The conductive connection part is fixed on one end of the electrical signal converter after passing through a locking hole.

[0013] The conductive connecting part is a fastener which can not only further fix the electric signal converter in the housing, but also form a stable electrical connection between the electric signal converter and the connecting line connected to the charged display.

[0014] Furthermore, a conductive fastener for fixing the other end of the electrical signal converter to the conductive connecting cylinder is provided in the conductive connecting cylinder.

[0015] The conductive fastener can not only prevent the conductive connecting tube from moving in the groove, but also form an additional connection point with the connecting copper bar, so as to improve the stability of the electrical connection between the electrical signal converter and the connecting copper bar.

[0016] Furthermore, the inner peripheral wall of the conductive connecting cylinder is provided with a threaded line that matches the connecting copper busbar.

[0017] The conductive connection tube and the connecting copper bar are connected by screw connection, which can improve the connection stability between the plug and the connecting copper bar and prevent it from falling off the connecting copper bar.

[0018] Furthermore, the housing is manufactured by integral injection molding.

[0019] In order to improve production efficiency, the electric signal converter can be placed in an injection mold and the shell of the plug can be manufactured by injection molding. Therefore, after the injection molding is completed, only a few simple assembly steps are required to obtain the finished plug, thereby improving production efficiency.

[0026] An electric signal converter 4 is arranged in the placement hole 12 in the housing 1. The electric signal converter 4 is a capacitor core rod. A conductive connection tube 2 is sleeved in the groove 11. The conductive connection tube 2 is fixed to one end of the electric signal converter 4 through a conductive fastener 21 inserted in the locking hole 13. A conductive connection part 3 is inserted in the locking hole 13 at the other end of the electric signal converter 4. The conductive connection part 3 is a conductive fastener and is used to fix a connection line (not shown in the figure) connected to a live display (not shown in the figure). A threaded line 22 that matches the connection copper bar 5 in the switch cabinet is also arranged on the inner peripheral wall of the conductive connection tube 2, and the conductive connection tube 2 is fixed to the connection copper bar 5 through the threaded line 22.

[0027] When this embodiment is used: the conductive connecting tube 2 is connected to the connecting copper bus 5 so that the high voltage electricity in the connecting copper bus 5 can flow to the electric signal converter 4 via the conductive connecting tube 2 or the conductive fastener 21. The electric signal converter 4 converts the high voltage current into an electric signal and transmits it to the conductive connecting part 3.
