[0002] An electric heater is a device that converts electrical current into heat energy to provide heating. These devices usually consist of one or more resistive elements that generate heat when current passes through them. Electric heaters are widely used in a variety of applications, including industrial, domestic, commercial and scientific laboratories.

[0003] At present, when the electric heater is used, it is necessary to connect the electric heater to a power source or a control system, and the connection is mainly made by using a plug-in terminal, which is a flag-type terminal or a straight plug-in terminal plugged into a crimping terminal to complete the connection work.

[0004] At present, the prior art uses a plug-in terminal method for connection. Although this method can complete the connection, after long-term use, the interface of this method is prone to loosening. Once the interface is loose, it may cause poor contact and the heater may not work properly. In severe cases, the interface is prone to fire, which may cause a safety accident.

[0005] Here we present a new type of heater connection. Summary of the invention

[0006] To this end, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the interface is prone to loosening after long-term use. Once the interface is loose, it may lead to poor contact and the heater cannot work normally. In severe cases, the interface is prone to fire, which may cause safety accidents.

[0008] In one embodiment of the utility model, the surfaces of the upper clamping plate and the lower base plate are both provided with connecting holes; the top of the upper clamping plate is threadedly connected to a limiting bolt through the connecting hole; one end of the limiting bolt passes through the upper clamping plate and extends to the bottom of the upper clamping plate.

[0009] In one embodiment of the utility model, the surface of the clamping cone is clamped with an electrically connected folding plate; the surface of the electrically connected folding plate is fixedly connected with a heater housing.

[0010] In one embodiment of the utility model, a power supply is provided on a side of the locking base plate away from the heater housing; and a conductive wire is fixedly connected to the surface of the power supply.

[0011] In one embodiment of the present invention, one end of the conductive wire extends to the top of the lower base plate; the surface of the conductive wire located on the top of the lower base plate is electrically connected to the surface of the electrical folding plate.

[0012] In one embodiment of the utility model, the short card block is folded and connected to the surface of the conductive wire; the long card block is folded and connected to the surface of the conductive wire; the short card block and the long card block are both used to limit the surface of the conductive wire.

[0013] The above technical solution of the utility model has the following advantages compared with the prior art:

The short clamping block 4 and the long clamping block 5 clamp and fix the conductive wire 12. The two ends of the conductive wire 12 are respectively fixed to the power supply 11 and the surface of the connecting electrical folding plate 9, thereby completing the internal power-on work and enabling the electric heater to start working. The connecting electrical folding plate 9 is clamped by the clamping cone 6 of the lower base plate 1, and then the upper clamping plate 14 cooperates with the folding block 13 to clamp on the top of the connecting electrical folding plate 9. In addition, the short clamping block 4 and the long clamping block 5 are folded again and clamped on the surface of the conductive wire 12 to clamp and fix the conductive wire 12.
