본 발명은 프리히터의 히트로드에 관한 것이다. The present invention relates to a heat rod of a preheater.

일반적으로 자동차등에서 냉각수 가열전 순간 발열되는 발열수단을 대체하는 새로운 부품으로서 이중 화재의 위험이 적고, 수명이 길어 반영구적으로 사용할 수 있는 금속단자가 탄착되는 수용체를 통해 정특성서미스터(正抵抗溫度係數를 가진 정특성서미스터:positive temperature coefficient thermistor, 이하 'PTC'라 함)가 널리 보급되어 있다.In general, it is a new component that replaces the heating means that generate heat immediately before heating the cooling water in automobiles. Positive temperature coefficient thermistor (hereinafter referred to as 'PTC') is widely used.

이러한 PTC를 이용한 난방용 예열장치에 적용되는 PTC 수용구조는 그 외측에 발열 및 방열을 위한 부품들이 함께 구현되어야 하므로 이것들을 고려한 절연가능한 다양한 배치구조가 제안되고 있다.Since the PTC receiving structure applied to the heating preheating apparatus using PTC must be implemented together with components for heat generation and heat dissipation on the outside thereof, various insulated arrangements considering these are proposed.

이중에서 본 출원인 선출원 제안한 예열장치의 PTC 수용구조는, Among them, the PTC receiving structure of the preheating device proposed by the applicant of the present application,

A receiver 10 having an accommodation groove 12 having a plate surface inwardly formed, and having insertion holes 16 alternately formed between the plate surfaces on which the accommodation grooves 12 are provided; PTC (13) is inserted into the receptor to be interviewed with the metal terminal (11); A cover member (1) having a substantially c-shaped cross section in which an accommodating space (15) is accommodated in a state where the PTC (13) is stacked and a second electrode is applied thereto; A cover member 2 having an I-shaped cross section connected / fixed at the opening side of the cover member 1; and as the PTC 13, the container 10, the cover member 1, and the cover member 2; Is done.

둘째, PTC를 단자의 양측면에 대응시켜 배치하여야 함에 따라 비효율적인 PTC 배치구조를 갖게 됨은 물론 PTC가 많아져 단가상승의 요인이 되어 왔다. Second, since PTC must be arranged in correspondence with both sides of the terminal, it has an inefficient PTC layout structure and, as a result, the number of PTCs has been a factor of increase in unit cost.

셋째, PTC의 배치를 일측면에만 구성할 경우 반대쪽에는 이에 대응하는 접착 절연체를 보강배치하여야 하므로 이를 근본적인 구조의 개선이 필요로 되었다. Third, when the arrangement of the PTC is configured only on one side, it is necessary to reinforce the corresponding adhesive insulator on the opposite side, and thus it is necessary to improve the fundamental structure.

본 발명은 종래의 이와 같은 문제점과 필요성을 감안하여 PTC의 일면배치에 적당한 조립구조를 제공함과 아울러 PTC 발열효율을 극대화시키며,부품수가 줄어들어 단가면에서 유리하며, PTC 배치/조립에 맞는 간단한 수용구조를 갖는 프리히터의 히트로드를 제공하는 데에 그 목적이 있다.
