Short chain-like ferrule structure, chain-like ferrule structure and method of producing chain-like ferrule structure

摘要

A short chain-like ferrule structure 15 includes a plurality of ferrules 2, and an interconnecting portion 16 interconnecting the plurality of ferrules 2. This ferrule structure includes a connection portion 20 provided at that portion of the interconnecting portion 16 projecting from the ferrule 2 disposed at one end portion of the ferrule structure, and a connection reception portion 21 which is provided at that portion of the interconnecting portion 16 projecting from the ferrule 2 disposed at the other end portion of the ferrule structure, and is engageable with the connection portion 20 of another short chain-like ferrule structure. Projections 23 are formed at the connection portion 20, and project from the interconnecting portion 16, and holes 25 for the passage of the projections 23 of another short chain-like ferrule structure therethrough are formed in the connection reception portion 21, and extend through the interconnecting portion 16. The connection portion 20 and the connection reception portion 21 provided respectively at any two adjacent short chain-like ferrule structures 15 beforehand molded are connected together, thereby forming a chain-like ferrule structure 1.
