Description
Technical field
The utility model relates to a kind of multi-functional quick electric heater and is connected and fixed clamping structure.
Background technology
In recent years along with the continuous development of domestic and international special industry, non-ferrous metal processing industry particularly, numerous industrial stoves such as fusing, insulation, annealing, heating, its electric heating temperature auto control system, great majority are to control the silicon controlled break-make by PLC, intelligence table, carry out Power Regulation then and realize.Mostly its heating element is to adopt Nie Chrome resistive band, Elema or radiant tube to heat.But since various dissimilar electric heater it internal structure and mounting means on have nothing in common with each other, its method of attachment mostly is star connection or delta-connection.When externally cable connected, comparatively old-fashioned connected mode was being used in continuity always for many years, specifically has: 1) delta connection, adopt the transition copper bar to add the method for attachment of wiring copper lug; 2) star connection has two kinds: a kind of is the method for all using the transition copper bar to be connected with the copper cable line, and another kind is that the star common port connects with a copper bar, and other end still adds the method for attachment of copper cable with the transition copper bar.
The common port of star connection is directly to connect with the short circuit busbar, and advantage is: no longer need to do the transition copper bar again and press the copper Wiring nose; Shortcoming is: because the position of each on-the-spot heater profile is unfixing, short circuit row is nonstandard so, be that the Installation and Debugging personnel have measured size and allow company make again to the scene, and then the scene of delivering installs, and size has deviation just can not install slightly like this, the words that the hole on the busbar enlarges, contact area during connection between busbar and the heater binding post has also just diminished, very dangerous, the rigid installation of the installation personnel that perhaps has causes the busbar distortion, and the people damages or the like for causing heater.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of multi-functional quick electric heater to be connected and fixed clamping structure.
The purpose of this utility model is achieved through the following technical solutions:
Electric heater is connected and fixed clamping structure, comprise terminal geometrical clamp, supercharging sheet and copper Wiring nose, characteristics are: described terminal geometrical clamp is the hollow type structure, and the upper end has tapped through hole, the bottom of its internal cavities is a circular groove, and tapped through hole is relative with circular groove; Described supercharging sheet is the circular arc thin slice, and the center of thin slice has shrinkage pool; Described copper Wiring nose is formed by connecting portion and operate portions linking, and operate portions is circular arc, and connecting portion is the ear shape, and has through hole; The copper cable line inserts in the terminal geometrical clamp, the operate portions of copper Wiring nose embeds in the cavity of terminal geometrical clamp, the operate portions of copper Wiring nose is blocked the copper cable line, the operate portions of supercharging sheet pressing copper Wiring nose, one clamping screw screws in the tapped through hole of geometrical clamp upper end, the top of clamping screw heads in the shrinkage pool of supercharging sheet, thereby, by the terminal geometrical clamp copper cable line and copper Wiring nose are connected as one.
Further, above-mentioned electric heater is connected and fixed clamping structure, and described clamping screw is a hexagon socket head cap screw.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
The utility model modern design, this multifunction electric heater is connected and fixed clamping structure does not need to make the transition busbar; Site operation is no longer employed heavy special-purpose line ball instrument; In the connection procedure rigid connection can not appear.It installs both convenient, and labor and material saving again can also better satisfy the linkage function of electric heater various ways.Cost is low, function is remarkable, and is ease in use, and economic benefit and social effect are remarkable.
