본 발명은 자동차용 프리 히터의 히터 하우징 구조에 관한 것으로 더 상세하게는 히터 하우징으로 결합하는 히트로드에 전극을 인가하는 그라운드 터미널의 구조를 개선하여 제작공정을 단순화하고, 다 수의 히트로드에 균일한 전극을 인가하도록 발명된 것이다.The present invention relates to a heater housing structure of a car pre-heater, and more particularly, to simplify the manufacturing process by improving the structure of the ground terminal for applying the electrode to the heat rod coupled to the heater housing, uniform to a plurality of heat rod It is invented to apply one electrode.

일반적으로 자동차에는 실내를 난방, 또는 냉방시키기 위한 공기조화장치가 설치되어 통풍계통 및 통풍경로를 통해 자동차 각부분에 냉기 및 난기를 골고루 이송시킨다.Generally, an air conditioner for heating or cooling an interior of a vehicle is installed to evenly transport cold and warm air to each part of the vehicle through a ventilation system and a ventilation path.

즉, 여름철등 실내의 온도를 낮추는 냉방의 경우에는 에어컨을 동작시켜 냉기를 토출시키고, 겨울철등 실내의 온도를 높이는 난방의 경우에는 엔진의 과열 방지를 위해 엔진 내부를 순환하여 가열된 냉각수를 송풍기를 통해 실내로 공급되는 외부공기와 열교환시켜 차량내의 곳곳에 배치된 토출구를 통해 온기를 공급하도록 한다.In other words, in the case of cooling to lower the indoor temperature in summer, the air conditioner is operated to discharge cold air. In the case of heating to increase the indoor temperature in winter, the coolant heated by circulating the inside of the engine is cooled to prevent the engine from overheating. Heat exchange with the outside air supplied into the room through the outlet to be supplied throughout the vehicle to supply the warmth.

그런데, 엔진과 열교환된 냉각수를 이용하여 실내를 난방하는 것이 효율적으로 바람직하기는 하나, 초기 시동 이후에 엔진이 가열되기까지의 시간이 경과해서야 가열된 냉각수를 이용하여 자동차 실내의 난방이 가능해진다.However, although it is preferable to efficiently heat the room by using the coolant heat exchanged with the engine, it is possible to heat the interior of the vehicle by using the heated coolant only after a time until the engine is heated after the initial start-up.

이러한 문제점을 해결하기 위하여 근래에는 정저항온도계수(正抵抗溫度係數)를 가진 정특성 서미스터(PTC:positive temperature coefficient thermistor, 이하 'PTC소자'라 함)를 사용한 프리 히터가 제안되고 있다.In order to solve this problem, in recent years, a pre-heater using a positive temperature coefficient thermistor (PTC) having a positive resistance temperature coefficient has been proposed.

이 프리 히터는 도 1에서 도시한 바와 같이 로드하우징(1a) 내에 내부에 발열체인 PTC소자를 내장하고, PTC소자에 전기전원을 공급하는 터미널(1b)이 관통되 어 결합한 히트로드(1)와, 이 히트로드(1)가 관통되어 결합하여 열을 발산하는 다 수의 방열핀(2)과 상기 히트로드(1)의 단부가 결합되며 전기전원부와 연계되어 하나의 전극을 인가하는 그라운드 터미널부재(20)가 구비된 히터하우징(10)을 포함한다.As shown in FIG. 1, the pre-heater includes a heat load 1 having a PTC element, which is a heating element, inside the load housing 1a, and a terminal 1b for supplying electric power to the PTC element therethrough. In addition, a plurality of heat dissipation fins 2 through which the heat rod 1 penetrates and dissipates heat and an end portion of the heat rod 1 are coupled, and a ground terminal member which is connected to an electric power supply unit and applies one electrode ( 20 is provided with a heater housing (10).

이 히터하우징(10)은 히트로드(1)가 결합되는 로드결합홈(11a)이 형성되며, 이 로드결합홈(11a)에는 히트로드(1)의 돌출된 터미널(1b)이 돌출되도록 결합하는 제 1 터미널관통구멍(10a)이 뚫려져 형성되고, 그라운드 터미널부재(20)의 터미널부(21)가 돌출되도록 결합되는 제 2 터미널관통구멍(10b)이 뚫려져 형성된다.The heater housing 10 has a rod coupling groove 11a to which the heat rod 1 is coupled, and the rod coupling groove 11a is coupled to the protrusion terminal 1b of the heat rod 1 so as to protrude. The first terminal through-hole 10a is formed to be drilled, and the second terminal through-hole 10b to which the terminal portion 21 of the ground terminal member 20 is protruded is formed to be drilled.

그리고 도 2에서 도시한 바와 같이 상기 히터하우징(10)에 구비되는 그라운드 터미널부재(20)는 하단에 터미널부(21)를 형성하고, 상단에 헤밍(Hemming)작업으로 중첩된 연결부(20a)와, 연결부(20a)의 상단 양측으로 각각 연장되어 절곡되어 로드결합홈(11a)으로 결합된 히트로드(1)의 외측면에 접촉하는 탄성접속편(20b)을 포함한다.As shown in FIG. 2, the ground terminal member 20 provided in the heater housing 10 has a terminal portion 21 formed at a lower end thereof, and a connection portion 20a superimposed by a hemming operation at an upper end thereof. The elastic connecting piece 20b extends to both sides of the upper end of the connecting portion 20a and is bent to contact the outer surface of the heat rod 1 coupled to the rod coupling groove 11a.

즉, 히터하우징(10)의 로드결합홈(11a)으로 히트로드(1)가 결합하면 히트로드(1)의 터미널(1b)은 제 1 터미널관통구멍(10a)을 통해 돌출되고, 로드하우징(1a)의 외측면이 그라운드 터미널부재(20)의 탄성접속편(20b)에 접속된다.That is, when the heat rod 1 is coupled to the rod coupling groove 11a of the heater housing 10, the terminal 1b of the heat rod 1 protrudes through the first terminal through hole 10a, and the rod housing ( The outer side surface of 1a is connected to the elastic connecting piece 20b of the ground terminal member 20.

그리고 상기 그라운드 터미널부재(20)는 그 터미널부(21)가 제 2 터미널관통구멍(10b)을 통해 결합하여 돌출되어 제 1 터미널관통구멍(10a)을 통해 돌출된 히트로드(1)의 터미널(1b)과 함께 전기 전원부로 연결되어 각각 다른 전극, 한쪽은 (+)전극 다른 한쪽은 (-)전극이 인가된다.In addition, the ground terminal member 20 has a terminal (21) of the heat rod (1) of which the terminal portion (21) is coupled and protruded through the second terminal through hole (10b) and protrudes through the first terminal through hole (10a). 1b) is connected to the electric power supply unit, and the other electrode, one side of the (+) electrode, the other side of the (-) electrode is applied.

이렇게 그라운드 터미널부재(20)와 히트로드(1)의 터미널(1b)에 각각 다른 전극이 인가되면 히트로드(1) 내부에 내장된 PCT소자는 로드하우징(1a)과 터미널(1b)로부터 각각 (+), (-)전극을 인가받아 발생되는 전류의 저항에 의해 발열되어 로드하우징을 가열하게 되는 것이다.Thus, when different electrodes are applied to the ground terminal member 20 and the terminal 1b of the heat rod 1, the PCT elements embedded in the heat rod 1 are respectively formed from the load housing 1a and the terminal 1b. +), (-) Is generated by the resistance of the current generated by the electrode to heat the load housing.

상기한 종래의 히터 하우징에서 그라운드 터미널부재가 각각 분리된 형상으로 연결부에서 연장되어 절곡된 탄성접속편으로 히트로드의 외측 일면에 접속하게 되므로 히트로드와 탄성접속편 사이에 접속불량이 발생할 위험이 높은 문제점이 있었던 것이다.In the above-described conventional heater housing, the ground terminal members are separated from each other by the elastic connection pieces that are bent and extended from the connection portions, so that the connection failure between the heat rods and the elastic connection pieces is high. There was a problem.

이렇게 히트로드와 어느 한 그라운드 터미널부재의 탄성접속편과의 접속불량이 일어날 경우 다른 그라운드 터미널부재로 전류가 집중되어 이 그라운드 터미널부재에 접속된 전선에 과대전류가 발생되는 문제점이 있었던 것이다. In this case, when the connection failure between the heat rod and the elastic connecting piece of one of the ground terminal members occurs, current is concentrated in the other ground terminal member, causing excessive current to occur in the wire connected to the ground terminal member.

또 별도로 다수의 그라운드 터미널을 제조해야 하므로 제조 공정이 복잡하고 제조 비용이 많이 소요되는 폐단이 있었던 것이다.In addition, since a large number of ground terminals must be manufactured separately, a manufacturing process is complicated and expensive.

본 발명의 목적은 히터 하우징에 구비되며 하나의 몸체로 형성된 그라운드 터미널을 히터 하우징에 견고히 결합하고, 제작 공정과 조립과정을 단순화하고, 히트로드를 견고하게 결합하여 접속시킬 수 있어 접속 불량에 따른 문제점을 해결할 수 있도록 한 자동차용 프리 히터의 히터 하우징 구조를 제공하는 데 있다.An object of the present invention is provided in the heater housing and the ground terminal formed of a single body firmly coupled to the heater housing, simplifying the manufacturing process and assembly process, can be connected to the heat rod firmly coupled to the problem of poor connection It is to provide a heater housing structure of a car pre-heater to solve the problem.

A ground terminal member coupled to an outer surface of the heat rod and having a terminal portion protruding through the terminal protrusion, wherein the ground terminal member integrally protrudes from the terminal portion protruding through the terminal protrusion and is coupled to the heat rod. In the heater housing structure of a pre-heater for automobiles formed of a connection panel portion in which a plurality of rod connecting holes are formed, the terminal portions are formed by engaging projections on both sides of the heater housing.

상기 그라운드 터미널부재는 다 수의 로드접속구멍이 뚫린 접속패널부로 형성되어 이 접속패널부의 로드접속구멍으로 히트로드가 결합하여 접속하게 되는 것이다.The ground terminal member is formed of a connecting panel portion having a plurality of rod connecting holes, and the heat rods are coupled to and connected to the rod connecting holes of the connecting panel portion.

그리고 상기 접속패널부에 터미널부가 일체로 형성되어 하나의 몸체로 형성되므로 그 제조가 용이하고 히터하우징에 한 번에 조립이 가능하며, 터미널부에 걸림돌기가 형성되어 히터하우징에 견고히 결합되는 것이다.And since the terminal portion is formed integrally with the connection panel portion is formed as a single body is easy to manufacture and can be assembled at the same time in the heater housing, the engaging projection is formed in the terminal portion is firmly coupled to the heater housing.
