Description

Technical Field

[0001] This invention relates to the field of low-voltage board-end socket technology, and more specifically to a low-voltage sheath terminal sealing structure. Background Technology

[0002] A low-voltage pin sheath structure refers to a protective device used in low-voltage electrical connectors. Typically, this structure consists of a pin and a sheath. The pin connects to the controller, while the sheath protects the pin and other parts of the connector from damage or environmental influences. The sheath can be made of various materials, such as plastics and rubber, offering good insulation and durability to ensure the stability and reliability of the connector. This structure is commonly used in various low-voltage electrical equipment, such as household appliances and electronic products, to provide a safe and reliable electrical connection.

[0003] At present, low-voltage sheath terminals mostly use radial sealing, which is achieved through a single layer of O-ring seal. If the single layer of O-ring seal ages or is scratched, problems such as rainwater seepage may occur, leading to seal failure and poor insulation.

[0004] In summary, a low-pressure sheath terminal sealing mechanism is proposed to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a low-pressure sheath terminal sealing structure, including a sheath body and a mounting base. The sheath body and the mounting base are connected. The mounting base is installed in the controller and connected to the sheath body. A multi-layer striped sealing ring is provided in the middle of the mounting base. Several terminals are also provided at the lower end of the mounting base. All of the terminals pass through the mounting base and are located in the sheath body.

[0006] Further specified, the upper end of the sheath body is open, and a cavity is provided inside. The terminal is located in the cavity, and a protective cover is provided at the upper end opening of the sheath body.

[0007] Furthermore, the sheath body is provided with two mounting holes, and the sheath body is connected to the controller through the two mounting holes.

[0008] Furthermore, the sheath body and the mounting base are integrally formed.

[0009] Furthermore, the mounting base has a multi-layered groove structure in its central part, and the multi-layered striped sealing ring is installed in the multi-layered groove structure. The dimensions of the multi-layered groove structure and the dimensions of the multi-layered striped sealing ring are matched.

[0010] The advantages of this utility model over the current technology are as follows:

[0011] 1. The multi-layered striped sealing ring reduces the risk of seal ring breakage due to compression during installation, thus improving the rainwater seepage protection level.

[0012] 2. It features a multi-layered groove structure, which facilitates the installation and fixation of the sealing ring and reduces the risk of seal failure due to misalignment of the sealing gasket during radial sealing installation. Attached Figure Description
