Problems solved by technology

[0004] The above-mentioned previous proposal connects the two conductive plates 11 and 12 of the positive and negative power supplies respectively, and the two are separated only by the PTC thermal resistance body 10 arranged in a scattered manner. The distance between the two conductive plates 11, 12 is not large, and there is a lack of poor insulation. If the locking components 14 are unevenly applied when they are combined, the distance between the two conductive plates 11, 12 will be drawn closer. Cause poor insulation, it is very likely that the two conductive plates 11, 12 will form a contact short circuit, causing safety concerns
Furthermore, the PTC thermal resistance body 10 is clamped between the two conductive plates 11 and 12, one end surface is only slightly embedded in the positioning groove 111 with a small groove depth of the first conductive plate 11, and the other end surface is supported by the other conductive plate 12. The elastic piece 121 resists, so combined with the structure, the PTC thermal resistance body 10 is easy to slip off due to insufficient embedding depth

Abstract

The present invention provides a PTC heater structure, which is mainly composed of an intermediate insulating plate sandwiched between two conductive plates with different polarities. The intermediate insulating plate is provided with notches corresponding to the positions of each PTC thermal resistance body for the PTC heating. The resistance body penetrates therein. Through the setting of the intermediate insulating plate, the two conductive plates with different electrical polarities are separated and insulated, and the assembly of the PTC thermal resistance body is more stable.

Description

【Technical field】 [0001] The present invention relates to a PTC heater structure, especially a PTC heater structure that can reliably separate and insulate two conductive plates with different polarities located inside the PTC heater, so as to provide greater safety when electrified. 【Background technique】 [0002] U.S. Patent No. 5,125,070, titled: PTC heater (Positive Temperature Coefficient Thermistors) patent case (hereinafter referred to as the previous case), invented and applied for by the inventor (such as Figures 1 to 3 As shown), the structure of the previous case is mainly that a plurality of honeycomb hole-shaped PTC thermal resistance bodies 10 are arranged in the middle, and a metal conductive plate 11, 12 and two conductive plates 11 are respectively arranged on both sides of the plurality of PTC thermal resistance bodies 10 , 12 The plate surface has notches 110 and 120 corresponding to the position of each PTC thermal resistance body 10; wherein, the inner w...
