Electric heating tube having sealing porcelain head with electric heating tube sleeve

Abstract

The invention provides an electric heating tube having a sealing porcelain head with an electric heating tube sleeve, and belongs to the field of electric heaters. A wiring end part of the electric heating tube is provided with a porcelain head integrating an electric heating tube sleeve sleeving the electric heating tube and a cavity containing a mounting nut, a power line and a wire pressing washer; a power line outlet for leading out the power line is arranged on the outer edge of the cavity of the porcelain head; a porcelain head cover is also arranged at the end part of a wiring screw of the electric heating tube; a wire pressing nut cavity capable of containing a wire pressing nut is arranged in the porcelain head cover; the electric heating tube is provided with a table ridge or table ring convenient for mounting the electric heating tube; and moreover, a mounting nut cavity convenient for mounting the electric heating tube and matched with the mounting nut in shape can be arranged in the cavity of the porcelain head. The electric heating tube provided by the invention has a good insulating and sealing effect and a compact whole structure, and is relatively convenient to mount.

Description

Technical field [0001] The electric heating pipe of the sealing porcelain head with an electric heating pipe cover of the present invention is an electrical heating pipe in the electric heating tube cover and the sealing structure of the wiring end, and the electrical heating tube sleeve and the wiring end.field. Background technique [0002] The patent number I applied for was 2012100820764, 20112201170754 patents provided a kind of installation and sealing structure of the electric heating pipe for use to use the available electrical heating pipes.Because the installation and sealing structure and the electric heating pipe are the split structure, there is a gap at the connection. This gap may cause the electric heating pipe to be loosened in the installation and use.The power supply is short -circuited in the gap between the board. Although this phenomenon rarely occurs, it is still necessary to be lost. In addition, the above structure still has a lack of compact structure. ...

Problems solved by technology

[0002] The patents I applied for are 2012100820764 and 2012201170754, which provide an installation and sealing structure for electric heating tubes, which are used in conjunction with a variety of ready-made electric heating tubes, so that the existing electric heating tubes can be easily installed and tightly insulated and sealed , because the installation and sealing structure and the electric heating tube are separate structures, there is a gap at the connection. This gap may make the connection of the electric heating tube loose during installation and use, and the box plate and bracket used to install the electric heating tube The board etc. fall into the gap and the power supply short circuit occurs. Although this phenomenon rarely occurs, it must be foolproof. In addition, the above structure still has the disadvantages that the structure is not compact enough, and the structure of the end of the electric heating tube is still too long.
