Abstract

본 발명은 휴즈와 휴즈캡의 결합구조에 관한 것으로서 종래의 휴즈는 착탈이 불편하고 용단상태의 확인이 육안으로 쉽게 판단되지 않는 결점이 있었다.The present invention relates to a coupling structure of a fuse and a fuse cap, and the conventional fuse has a drawback that the detachment is inconvenient and the identification of the blown state is not easily determined by the naked eye.

본 발명은 예시도면 제3도와 같이 휴즈(2)를 휴즈캡(1)에 결합하여 양측의 휴즈선(3)(4)을 휴즈캡(1)의 판스프링단자(5)와 단자(6)에 결합하고, 휴즈캡(1)을 하부케이스(8)에 결합하면 판스프링단자(5)와 단자(6)가 각각 하부케이스(8)의 삽입공(18)(19)에 삽입되면서 접속편(9)(10)에 접속되도록 한 것이며, 상부케이스(12)에는 투시창(11)을 형성하여 판스프링단자(5)의 상태, 즉 휴즈의 용단여부를 확인할 수 있도록 한 것임.According to the present invention, as shown in FIG. 3, the fuse 2 is connected to the fuse cap 1 so that the fuse wires 3 and 4 on both sides are connected to the leaf spring terminal 5 and the terminal 6 of the fuse cap 1. When the fuse cap 1 is coupled to the lower case 8, the leaf spring terminal 5 and the terminal 6 are inserted into the insertion holes 18 and 19 of the lower case 8, respectively. (9) (10) is to be connected, the upper case 12 is to form a see-through window 11 to check the state of the leaf spring terminal (5), that is, whether the fuse blown.
