Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a quick-connection type power distribution switch. Background Art

[0002] The principle of the switch is that the "closed" contact means that the electronic contact is conducting, allowing current to flow; "open" means that the electronic contact is not conducting, forming an open circuit, and does not allow current to flow. It consists of a panel, switch current-carrying parts, switch contacts, switch nozzles, bases and other structures. According to the purpose, it can be divided into wave switches, band switches, recording and playback switches, power switches, pre-selection switches, etc.

[0003] During the use of existing distribution switches, auxiliary tools are required to lock the installed wires, which makes the installation process complicated and the effect is poor. In addition, leakage detection cannot be achieved. Once leakage occurs, it is easy to cause a fire if it is not handled in time, resulting in poor practicality of the distribution switch. Utility Model Content

[0004] The purpose of the utility model is to provide a quick-connection type power distribution switch, which is used to overcome the above-mentioned defects in the prior art.

[0006] In some embodiments, the main box body is provided with two groups of clamping cavities connected to the outside and symmetrically, and interpenetrating with the threaded cavity. A conductive metal sheet is fixed in the upper wall of the clamping cavity and penetrates the rear wall of the clamping cavity.

[0007] In some embodiments, an insulating gasket is fixedly provided at the other end of the pneumatic telescopic rod, and a metal block is fixedly provided on the rear end surface of the insulating gasket and abuts against the conductive metal sheet.

[0008] In some embodiments, a leakage alarm is fixedly provided on the rear wall of the pushing cavity, so that the leakage alarm plays a role in detecting leakage. A detection probe is fixedly provided on the front end surface of the leakage alarm and abuts against the metal block.

[0009] In some embodiments, a glass plate is fixedly provided on the front wall of the protective shell, a controller is fixedly provided on the front end surface of the protective shell, and the controller plays a coordinating role in regulating various movements, and an alarm is fixedly provided on the lower end surface of the protective shell, and the alarm plays an alarm role.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] 1. The utility model starts to rotate the insulating screw, and then the two groups of threaded sliders with left and right symmetry and opposite threads start to move away from the clamping plate. At this time, the clamping plate cooperates with the conductive metal sheet to achieve docking of wires of different diameters and different models, thereby ensuring rapid wiring, further changing the existing problem that the docking wires and the connected wires cannot be docked at the same time and auxiliary tools are required, further greatly shortening the installation time of the distribution switch, thereby ensuring the practicality of the distribution switch.

[0012] 2. The utility model realizes the circulation of the circuit by transmitting the current from the conductive metal sheet on one side through the metal block to the conductive metal sheet on the other side. At this time, the current will enter the detection probe, and the leakage will be found through the detection of the leakage alarm. At the same time, the controller starts to control the pneumatic telescopic rod to start shrinking, and then drives the insulating gasket and the metal block away from the two groups of conductive metal sheets that are symmetrical on the left and right, thereby ensuring that the power supply can be disconnected in time, thereby realizing power-off protection, thereby ensuring the safety of the user and further ensuring the practicality of the distribution switch.

[0013] 3. The utility model detects leakage through the detection of leakage alarm, and the alarm starts to sound an alarm, thereby ensuring that the user can discover and deal with it in time, thereby preventing fire or electric shock caused by leakage, thereby ensuring the safety of the user, and the value of the leakage alarm can be observed in real time through the glass plate, thereby ensuring the practicality of the distribution switch.

[0029] Specific workflow:

[0030] When in use, the wires to be connected are placed in the two groups of clamping cavities 17 on the left and right sides respectively. The user then starts to rotate the insulating screw 13, and the two groups of threaded sliders 14 that are symmetrical on the left and right and have opposite threads start to move away from the clamping plate 15.
