Description

Technical Field

[0001] The present invention relates to the technical field of power distribution terminals, in particular to a power distribution terminal with a circuit protection function. Background Art

[0002] The distribution terminal is a general term for various remote monitoring and control units installed in the distribution network. It is a terminal device in the power system with multiple functions such as connecting cables, protecting power equipment, and transmitting power signals. The distribution terminal can complete tasks such as data acquisition, control, and communication. It is an important component of electrical equipment and provides multiple protections for power equipment, such as overcurrent, short circuit, and overvoltage protection. When abnormal current or voltage appears in the circuit, the distribution terminal can quickly cut off the circuit to prevent damage to the power equipment.

[0003] After searching, the invention patent with publication number CN117954996A discloses a distribution terminal DTU with circuit protection function and a method of use. The heat sink can be used to cool the distribution terminal, thereby improving the temperature stability of the distribution terminal during operation; and a cleaning brush is used to make circular motions along the surface of the dust screen to clean dust particles accumulated on the surface of the dust screen for a long time, thereby improving the ventilation effect inside the outer shell.

[0004] In the above scheme, the distribution terminal is placed on the support seat and fixed with the clamping plates on both sides. The distribution terminal needs to be kept flat. When it is placed tilted and off-center, the position of the distribution terminal will be offset due to the pushing action of the clamping plate. The uneven clamping force may even cause deformation or damage to the surface of the distribution terminal, affecting its operation. There is also a method of installing the distribution terminal on the inner wall of the shell, but the small gap inside the shell makes it difficult to tighten. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, by setting a length adjustment component, the two docking parts are fixedly connected by a limiting rod, which is convenient for quickly aligning the position of the docking part with the corresponding clamping groove. By changing the position of the contact plate and the docking part, it can adapt to the installation of connection shells of different lengths, thereby improving its installation and use range. The specific operation is to toggle the handle, and the handle drives the adjusting screw to rotate. Under the threaded connection, the contact plate slides in a limited position in the slide rod. At this time, the position of the contact plate away from the docking part changes, and the gap between the contact plate and the docking part is used to store the connecting wire in the storage recess. Then, the connection shell is placed between the fixed card block and the movable card block. Since the fixed card block is immovable, the top surface of the connection shell abuts against the movable card block when sliding, so that the movable card block is subjected to an upward thrust, and then the connection shell is clamped between the movable card block and the fixed card block. After the clamping of the connection shell is completed, the clamping design of the docking part and the clamping groove is used to limit the installation in the outer shell, thereby increasing its installation stability. No other installation tools are required, which is convenient and quick. The power distribution terminal body is clamped by the inflatable abutment protection component without alignment.

[0022] 2. When the power distribution terminal body is installed in the connecting shell, the top of the balloon pipe is inserted into the air inlet pipe. At this time, the ring block abuts against the bottom surface of the air inlet pipe, so that the compression spring 3 is elastically compressed. At the same time, by pressing the holding part, the elastic sheet is tilted inward and enters the interior of the lock groove. Then the elastic sheet is reset, and the holding part abuts against the bottom surface of the connecting sheet, so that the balloon and the air inlet pipe are connected together, which is convenient for pressing and inflating operation. The gas enters the air bags on both sides through the air inlet pipe. At this time, the air bags are filled with gas and expand, and the volume increases, pushing the corresponding buffer plate to move to one side, that is, the slider moves in the slide groove and elastically squeezes the compression spring 2. At this time, the buffer plate abuts and contacts with the power distribution terminal body to complete the buffer limit;

[0023] 3. Insert the connecting wires into the interior of the wiring tube through the notch, hide the wiring installation, arrange it in layers, make the wiring more regular and easy to find, then pass the end of the tensioning rope through the fixing ring and adhere it with Velcro to tighten the wiring tube to make the opening of the notch smaller and prevent the connecting wires from falling off.
