Claims (1)

[Scope of Claim for Utility Model Registration] A plurality of pairs consisting of a male type and a female type, each of which connects a plurality of covered electric wires K which are arranged in parallel, and which are inserted into each other to establish an electrical connection. A pair of female and male insulators A and B for inserting and covering electric wire connection terminals 1 and 11, and a connection portion of a metal connection terminal 1 having a wire clamping portion 1a and either a male or female connection portion 1b. 1b penetrates therethrough and fixedly holds the connecting terminal 1; and the connecting terminal 1.
A covering tube 2 made of synthetic resin in which a cover section 2a into which the holding section 1a of the above is fitted and a male side extension cylindrical section 2c which is fitted into the other extension cylindrical section 12c are formed in a row on the left and right, and the covering tube 2 A heat-shrinkable wire having a continuous part 3a glued and continuous on at least the covering part 2a of the wire, a mantle part 3b covering the covering part c of the covered electric wire k, and a heat-melting resin layer 3c adhered to the inner surface of the mantle part 3b. The tube 3 has a circumscribed shape that circumscribes the covering portion c of the plurality of insulated electric wires k arranged in parallel, and the covering portion of the plurality of insulated electric wires k arranged in parallel is fitted to each end. A male insulating device A consisting of a spacer 4 having recessed portions 4a formed therein, a wire holding portion 11a, and the connecting portion 1b.
A cover portion into which the clamping portion 11a of the metal connection terminal 11 is fitted, and a connecting portion 11b that fits into the connecting portion 11b to make an electrical connection. 12c formed in a row on the left and right, a continuous part 13a adhesively connected on at least the covering part 12a of the covering cylinder 12, and a mantle that covers the covering part c of the covered electric wire k... A heat-shrinkable tube 13 having a portion 13b and a hot-melt resin layer 3c adhered to its inner surface, and a spacer 4 as well.
and an extended cylindrical portion 2c of both synthetic resin covering tubes 2 and 12.
, 12c are formed in such a length that they fit together with the mating extension cylindrical parts 12c, 2c when the connecting parts 1b, 11b of the terminals 1, 11 are inserted and fitted together, and these extension cylindrical parts A watertight insulator for a wire connection terminal in which a watertight ring 5 is attached to a portion corresponding to the fitting portion position of 2c and 12c.
