The present invention relates to a production method of vehicle electronic units. The production method according to the present invention comprises: a first step of producing a first terminal module having a molding part using a metallic wiring unit; a second step of producing a secondary terminal module by forming a waterproof molding layer on the molding part of the first terminal module; and a third step of producing a housing of the electronic units by insert molding using the second terminal module. Since the terminal module in which the waterproof molding layer is additionally formed on the molding part is integrated with the housing, a gap through which moisture can penetrate from the outside of the housing is fundamentally prevented unlike the conventional one, thereby greatly improving the watertight performance of the vehicle electronic units.

    본 발명은 차량 전장품의 제조방법을 개시한다. 본 발명에 따른 제조방법은, 금속재질의 배선유닛을 이용하여 몰딩부를 구비하는 1차 단자모듈을 제조하는 1차 단계; 상기 1차 단자모듈의 몰딩부에 방수몰딩층을 형성하여 2차 단자모듈을 제조하는 2차 단계; 상기 2차 단자모듈을 이용한 인서트 성형으로 전장품의 하우징을 제조하는 3차 단계를 포함한다. 본 발명에 따르면, 몰딩부에 방수몰딩층이 추가로 형성된 단자모듈이 하우징과 일체화되므로 종래와 달리 하우징의 바깥쪽에서 수분이 침투할 수 있는 틈새가 근본적으로 방지되고, 이를 통해 차량 전장품의 수밀 성능을 크게 향상시킬 수 있다.
