Abstract
Abstract A connector comprises an insulating casing of a bottomed box-shape having in the bottom wire-end insert holes, a conductive contact means of an angled tubular shape complementarily inserted into the casing to dispose both open ends of the means substantially adjacent the bottom and opposing open end of the casing, a plurality of conductive resilient means arranged within the contact means to extend between the bottom and the open end of the casing and to respectively align with each of the wire-end insert holes, the resilient means functioning to cause wire ends for interconnection to be urged into contact commonly with the contact means as inserted between the resilient and contact means and simultaneously to be prevented from being pulled out of the contacting position, and a lid secured to the open end of the casing, the respective members being manufactured in a simple manner and assembled by inserting them into the casing in the same direction, rendering the productivity of the connector to be remarkably improved.
