Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1-5, the utility model provides a connect stable PTC heater mounting, its structure includes mounting body, and mounting body includes heater connecting seat 1, terminal fixing base 2, assembly seat 3 from bottom to top. Wherein, a through hole 101 is arranged in the heater connecting seat 1, and the through hole is used for inserting the electrode of the PTC heater. The top end of the electrode penetrates out of the through hole, and the part of the electrode enters the terminal fixing seat and is used for being connected with a power supply terminal.

Specifically, the whole through hole 101 is in a trapezoid shape with a large outside and a small inside, the middle upper part of the trapezoid is slightly smaller than the width of the electrode plate, and the fixing piece is made of plastic with certain elasticity, so that the electrode plate is pressed by the inner wall of the middle upper part of the through hole when inserted into the through hole, the effect of tightening the electrode plate is achieved, and the connection stability is improved. Specifically, as shown in fig. 1 and 6, the through-hole has a three-stage shape, a rectangular bottom section for accommodating the bottom transition section of the electrode sheet 4, a trapezoidal middle section for accommodating the electrode sheet main body 402, and a rectangular top section for accommodating the connecting piece 403 at the top of the electrode sheet.

As shown in fig. 5, a screw hole 104 is formed at one side of the heater connecting holder 1, and the screw hole is communicated with the through hole, so that a screw can be inserted into the screw hole and then be threadedly connected with the side surface of the PTC heater.
