Abstract:
1. A terminal connector with easy entry configured for interconnecting a conducting terminal and at least one conducting wire, in which each said conducting wire comprises a conducting core and an insulating cladding enclosing the conducting core, and the terminal connector comprises: an insulating tube; a conducting terminal including a first end accommodated in the insulating tube, a second end opposite to the first end and being exposed to an outside for connecting to an external conducting contact point; and a soldering sleeve arranged on a longitudinal elongation of the conducing terminal; characterized in that the insulating tube shrinks to deform when being heated to a temperature higher than a first temperature and has a melting point at a second temperature; the first end of the conducting terminal is bent to form the longitudinal elongation with an opening facing upward; and wherein the soldering sleeve has a melting point at a third temperature that is between the first temperature and the second temperature, the soldering sleeve includes an outer surface that is corrugated, one end of the soldering sleeve extends out of the longitudinal elongation of the conducting terminal, and the extend-out section of soldering sleeve includes a radially gradually enlarged portion; wherein when a heat source is appropriately 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 gaps in the corrugated outer surface and affix to an end surface outside an end point of the radially enlarged portion, an inner periphery of the insulating tube forms a gradually converging configuration oriented toward the end point of the radially enlarged portion of the soldering sleeve, thereby achieving the terminal 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.
