Electrically heated hollow glass and manufacturing method thereof

Abstract

The invention relates to the technical field of door frame structures, and provides a piece of electrically heated hollow glass which is attractive and elegant in appearance and lower in cost and improves the sealing reliability. The electrically heated hollow glass comprises outer glass, a cross bar assembly and inner glass, wherein the outer glass and the inner glass are respectively arranged on the front side and the rear side of the cross bar component; the outer glass comprises a glass main body, an electrical heating film and a conductive silver paste bar; the cross bar assembly comprises cross bars, inflatable insertion corners and contact piece insertion corners, the cross bars are connected into a square structure by the inflatable insertion corners and the contact piece insertion corners; a decorative film is arranged between the glass main body and the electrical heating film; each contact piece insertion corner comprises a conductive contact piece, a plastic insertion corner and a lead wire, and the conductive contact piece is integrally formed with the plastic insertion corner after being connected with the lead wire. As the decorative film is arranged on the outer glass, the product attractiveness is improved and the product cost is lowered. Meanwhile, as the integrated contact piece insertion corners are adopted, the sealing reliability can be remarkably improved. The invention further provides a manufacturing method of the electrically heated hollow glass.

Description

technical field [0001] The present invention relates to the technical field of door frame structures, and more particularly, to an electrically heated insulating glass and a manufacturing method thereof. Background technique [0002] In the prior art, the hollow glass doors of refrigerated display cabinets on the market have the defect of no decorative effect or single decorative effect. Most of the electrically heated insulating glass has no decorative effect. In order to achieve the purpose of beauty, an additional piece of decorative glass is usually added, which increases the weight of the product and also increases the cost of manufacturing, assembly and transportation. In addition, the electrode connection of the existing electric heating insulating glass usually uses spliced ​​conductive contact gussets to energize the electric heating film. This spliced ​​contact gusset structure has the defect of poor sealing, and the external moist air is easy to pass along the wir...

Problems solved by technology

[0002] In the prior art, the hollow glass doors of refrigeration display cabinets on the market have the defect of no decorative effect or single decorative effect

Among them, most of the electric heating insulating glass has no decorative effect. In order to achieve the purpose of beauty, an additional piece of decorative glass is usually added, which increases the weight of the product and also increases the cost of manufacturing, assembly and transportation.

In addition, the electrode connection of the existing electric heating insulating glass usually adopts spliced ​​conductive contact angles to energize the electric heating film. This type of spliced ​​contact angle structure has the defect of poor sealing, and the external moist air is easy to flow along the wire core. Penetrating into the insulating glass, resulting in condensation in the insulating glass, reducing the insulating effect of the insulating glass, and also has the risk of damaging the electric heating film
