題点があった。However, none of these known means is effective in the bonding force between the insulating sleeve bands, particularly in the tensile strength along the longitudinal direction, and all are flat connecting plate portions. However, since the connecting plate portion needs to have a certain length, the pitch of the insulating sleeve cannot be reduced to a certain value or more. In addition, the lamination of the connecting plate portions deteriorates the flexibility of the long insulating sleeve band, making it impossible to cleanly wind up in a loop shape, or disconnecting the connecting plate portions when trying to bend forcibly. There was a problem.

It is a main object of the present invention to provide a long insulating sleeve band for an electric connector, which can speed up the operation of loading an electric connector element by an automatic machine.

きる。After the insulating sleeve band 3 having a unit length is molded by the mold 4 in this manner, the upper and lower split dies 4a, 4b
In addition, the core mold 4c is separated to take out the insulating sleeve band 3 as shown in FIG. 3, and the small-diameter insulating sleeve 1a at the left end is fitted into the core mold 4c at the right end of the mold 4 as shown in FIG. Then, the upper and lower molds are closed, and the molten resin is poured to form the insulating sleeve band 3 having the next unit length. The insulating sleeve 1b at the right end of the unit length insulating sleeve band 3 formed in this way is formed around the insulating sleeve 1a portion of the unit length insulating sleeve band 3 formed earlier and integrally welded and joined. Is done. By repeating this molding means, a long insulating sleeve band in which a plurality of insulating sleeve bands 3 are connected is manufactured. In the long insulating sleeve band for an electrical connector manufactured in this manner, since the adjacent insulating sleeve bands 3 are welded and connected in a double-layered structure with the insulating sleeves 1a and 1b, the bonding strength is extremely strong. In addition, since the connecting plates are not stacked and connected as in the related art, the pitch of the insulating sleeves 1 can be reduced without deteriorating the flexibility of the connecting plates.
