Abstract
The utility model relates to an electric heating device with novel electric connecting joint, comprising an insulating basal body, an electric heating membrane, electrode films and two electric connecting joints. The utility model is characterized in that the insulating basal body is a rod with a through-hole, and the electrode films are arranged at the both ends of the through-hole of the rod. The two electric connecting joints are arranged at the both ends of the rod. Each electric connecting joint is composed of a U-shaped elastic metal sheet, an insulating block and a metal tightly pressing piece, and the U-shaped metal sheet can tightly press the electrode film by the metal tightly pressing piece. The electric heating device has the advantages of simple structure, easy fabrication, convenient assemblage, reliable connection and high productive efficiency.
Description
The utility model relates to a kind of electrothermal device, relates in particular to a kind of electrothermal device with novel electric connecting joint.
The serve as reasons matrix of insulation, Electric radiant Heating Film, layer electrodes and the electric connecting joint of being located on the matrix of electrothermal device commonly used formed, because used electric connecting joint complex structure, connection reliability are poor, often make the electrothermal device blank area volume difficulty of producing extensively, inconvenience is installed and very undesirable, the utmost point need improve.
The purpose of this utility model is to provide a kind of jointing of easy-to-install new construction simple in structure, easy to make, and is easy to assembly and have good electrical connection so that electrothermal device is made is simple, and can improve productivity ratio.
The purpose of this utility model is to realize like this, a kind of electrothermal device with novel electric connecting joint, include insulating body, Electric radiant Heating Film, layer electrodes and electric connecting joint, it is characterized in that insulating body is one to have the rod of through hole, layer electrodes is located at the two ends of excellent through hole, two electric connecting joints are located at the two ends of rod respectively, each electric connecting joint is by elastic sheet metal, insulation link stopper and metal press part to be formed, wherein insulating spacer is arranged at matrix insulating rod two ends, elastic sheet metal is the shape sheet metal that takes the shape of the letter U, and its bottom is posted by on the block, and the tapered shape in its both sides, metal presses part and presses in sheet metal U-shaped opening, and makes sheet deformation and press on layer electrodes.
The advantage of the electrothermal device of said structure is that processing and fabricating is simple, easy to assembly, connects reliably the good and productivity ratio height of quality.
With embodiment and accompanying drawing structure of the present utility model is further narrated below
Embodiment pipe heater spare
Description of drawings
Fig. 1 is the overall structure schematic diagram of pipe heater spare
Fig. 2 is the structure chart of the electric connecting joint among Fig. 1
Fig. 3 is the A-A cutaway view of Fig. 2
By shown in Fig. 1-3 as seen, the pipe heater spare of present embodiment is made up of earthenware matrix 1, Electric radiant Heating Film 2, layer electrodes 3 and electric connecting joint 4.Electric connecting joint 4 includes U-shaped elastic sheet metal 41, insulating ceramics first speed piece 42 and metal fastener 43, and wherein metal fastener 43 is to be made up of screw 431 packing rings 432 and nut 433.During assembling, screw 431 is sheathed in the U-shaped sheet metal 41, be positioned in the hole of electrothermal tube, put ceramic head 42 then, load onto packing ring 432, nut 433 in screw 431 exposed sections again, turn nut 433, screw 431 is just to overhanging, and meanwhile the U-shaped opening of U-shaped sheet metal constantly extends out till layer electrodes in sheet metal and pipe fitting hole compresses.
As seen from the above-described embodiment, this electrothermal device has been owing to adopted novel electric connecting joint to make its structure greatly simple, and easy to make, and connection reliability is good, thereby makes advantages such as the utlity model has high-quality, high efficiency.
