Abstract:
1. A wire connector with easy entry configured to interconnect multiple wires, wherein each wire comprising a conducting core and an insulating cladding enclosing the conducting core, comprising: an insulating tube having a characteristic of shrinking when being heated to a temperature higher than a first temperature and having a melting point at a second temperature; and a soldering sleeve disposed in the insulating tube and having a melting point at a third temperature that is between the first temperature and the second temperature, in which the soldering sleeve has an outer surface that is corrugated; characterized in that the soldering sleeve comprises a pair of smoothly radially expanded portions at two ends thereof, and when a heat source is properly applied to an outer periphery of the insulating tube that corresponds to the soldering sleeve to heat the insulating tube to a temperature above the first temperature but below the third temperature, causing the heated insulating tube to shrink to lodge into corrugation gaps of the outer surface and affix to end surfaces outside end points of the radially expanded portions, an inner periphery of the insulating tube forms a smoothly converging configuration oriented toward each end point of the radially expanded portion, thereby achieving the wire connector with easy entry such that the insulating tube and the soldering sleeve are tightly connected and the conducting core is allowed to be readily inserted from the two ends of the soldering sleeve.
