Problems solved by technology
Since a thermostat is installed on the top of the PTC electric heating device, the installation position of the electrical connection terminal is limited
Therefore, the electrical connection terminals of traditional PTC electric heating devices are all arranged at the bottom thereof, and the terminals are connected with the circuit board on the top of the body with long wires. Obviously, this structure not only causes a large amount of waste of connecting wires, but also takes up a relatively large area. Too much space inside the machine leads to an increase in the volume of the machine, and causes inconvenience in installation and potential failures due to wires winding through the heating element.

Embodiment Construction
[0021] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.
[0022] The electrical connection structure of the heating element of the heater according to the present invention mainly relates to the electrical connection part of the electric heating device of the heater, and other parts of the heater will not be described in detail.
[0023] refer to figure 2 , image 3 , the electrical connection structure of the heating element of the heater includes a PTC heating component 10 , an electrical connection terminal 20 and a bracket 30 of the heating component. The structure of the PTC heating component 10 is as follows: figure 1 As shown, it includes a PTC heating sheet 11, a metal radiator 12 and a metal side plate 13. According to the area to be heated and the volume of the heater, the PTC heating sheet 11 can be used in conjunction with a single group of radiators 12. It...

An electrical connection structure of a heater heating body, the structure comprising a PTC heating component (10), one or more electrical connection terminals (20) connected to the PTC heating component and a heating component bracket (30), characterized in that the Among the one or more electrical connection terminals (20), one of the first electrical connection terminals (21) is arranged on the upper side of the PTC heating element (10), and the remaining second electrical connection terminals (22) are arranged on the PTC heating element (10) top. The electric connection structure of the present invention can not only make the assembly of the PTC electric heating device convenient and fast, but also save a lot of wires, and make the electric connection of the PTC electric heating device safe and reliable.
Description
【Technical field】 [0001] The invention relates to a heater for heating indoor air, in particular to an electrical connection structure of a heating element of the heater which saves material and is easy to assemble. 【Background technique】 [0002] Electric heating devices are installed on small household electric heating products such as heaters to heat media such as air and water. Traditional electric heating devices include resistance wires, electric heating sheets, electric heating tubes, etc. These electric heating devices have no temperature adjustment function, so the service life is short, the failure rate is high, and the safety is poor. Another electric heating device called PTC (Positive Temperature Coefficient) replaces traditional heating devices because of its high reliability, convenient use, safety, and power saving. It is widely used in power facilities, electronic equipment and the automotive industry. and many other fields. This PTC electrothermal device ...
