Description

Technical Field

[0001] This utility model relates to the field of electrical protection device technology, specifically a sealing mechanism for an electrical protection device. Background Technology

[0002] Electrical safety devices are crucial for ensuring electrical safety. They quickly cut off power in case of leakage, overload, or short circuit, preventing electric shock and electrical fires. Their core principle is based on current balance detection. When the difference between the current in the live wire and the neutral wire exceeds a set value, a tripping mechanism is triggered to disconnect the circuit, with a response time of only 0.1 seconds, effectively protecting personal safety. Products are available in household and industrial grades, featuring overload protection, short circuit protection, and leakage self-testing functions. Some models also support remote monitoring.

[0003] Utility model patent CN221202129U discloses a sealing mechanism for an electrical protection device, relating to the field of electrical protection device technology. This sealing mechanism includes an electrical protection device with a rectangular groove on its upper surface. An electric wire contacts the inner wall of the rectangular groove, and a rubber block is fixedly connected to the outer wall of the electric wire. A groove is formed on the inner wall of the rectangular groove, and a sleeve is slidably connected to the inner wall of the groove. A sealing block is fixedly connected to the left surface of the sleeve, and the inner wall of the sleeve is elastically connected to the inner wall of the groove by a spring. This utility model improves the sealing performance of the electrical protection device's wiring port by increasing the contact area between the sealing block and the rubber block when the electric wire is inserted into the device, preventing dust from entering and extending its service life.

[0004] However, the sealing mechanism of this power protector requires modification of both the wire and the power protector, which reduces the compatibility with the wire and results in poor sealing performance for ordinary wires. Therefore, a sealing mechanism for the power protector is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sealing mechanism for an electrical protection device, which has advantages such as improving the sealing effect between the electrical protection device and ordinary wires, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sealing mechanism for an electrical protector includes a protector body, wherein a wiring conduit is fixedly installed at both the output and input ends of the protector body, a sealing tube is fixedly installed at one end of the wiring conduit, and a sealing component is provided inside the sealing tube;

[0008] The sealing assembly includes a sealing airbag fixedly installed on the inner wall of the sealing tube. An air supply pipe is fixedly installed on the top of the sealing airbag, and the top end of the air supply pipe extends to the outside of the sealing tube. A one-way valve is fixedly installed on the surface of the air supply pipe. An inflation sleeve is fixedly installed on the top end of the air supply pipe. A connecting pipe is slidably installed inside the inflation sleeve. An elastic soft shell is fixedly installed on the top end of the connecting pipe. A support tail plate is fixedly installed on the top end of the elastic soft shell.

[0009] Furthermore, an air blowing ring is fixedly installed on the inner wall of the sealing tube near its outer end, and one side of the air blowing ring has a bevel.

[0010] Furthermore, a jet pipe is fixedly installed on one side of the inclined side, and a dust removal pipe is fixedly installed at the top of the air blowing ring pipe.

[0011] Furthermore, the top end of the dust removal pipe extends to the outside of the sealing pipe, and a dust removal sleeve is fixedly installed at the top end of the dust removal pipe, which is compatible with the connecting pipe.

[0012] Furthermore, a locking screw is threaded onto the top of the conduit, with the bottom end of the locking screw extending into the interior of the conduit.

[0013] Furthermore, a display panel is fixedly installed on the top of the protector body, and a gate arm is rotatably installed inside the protector body.

[0014] Furthermore, the top of the display panel is provided with a sliding groove that matches the gate arm, a status indicator light is fixedly installed on the top of the display panel, and four mounting feet are fixedly installed on the side of the protector body.

[0015] Compared with the prior art, the present invention provides a sealing mechanism for an electrical protector, which has the following advantages:

[0016] 1. The sealing mechanism of this electrical protector involves setting a sealing tube at one end of the wiring conduit. The wire core is inserted into the wiring conduit, and the connecting pipe is inserted into the air-filled sleeve. Pressing the elastic soft shell inflates the sealing airbag, causing it to expand and contact the surface of the wire inside the sealing tube to seal it and prevent external dust from entering. It has high compatibility and does not require modification of the wires. It solves the problem of poor sealing effect of common electrical protectors at the wire connection parts, which makes it easy for dust to enter the electrical protector.

[0017] 2. The sealing mechanism of this electrical protector is achieved by setting an inclined side inside the sealing tube, and setting an air jet pipe on the inclined side. The connecting pipe is inserted into the dust removal sleeve, the elastic soft shell is pressed, and air is filled into the blowing ring pipe. The airflow is ejected through the air jet pipe, blowing out the dust attached to the sealing airbag and the surface of the wire. Attached Figure Description
