Abstract:
1. An electrical power connector preparation method, comprising the steps of: (a) employing a cold drawing technique to draw a metal round rod into a thin thickness conducting contact bar; (b) processing one end of said thin thickness conducting contact bar into a mating contact portion; (c) stamping a part of said thin thickness conducting contact to form a mounting portion; (d) attaching a part of said mounting portion of said thin thickness conducting contact to one of a plurality of locating notches of one contact material strip and then cutting off said thin thickness conducting contact subject to a predetermined length to obtain a finished metal contact; (e) repeating steps (a)˜(d) to obtain a plurality of said metal contacts and to have said metal contacts be positioned in respective locating notches of at least one said contact material strip in such a manner that a predetermined number of said metal contacts is arranged in a set and multiple sets of said metal contacts are spaced from one another along the length of said at least one contact material strip at a predetermined interval; (f) electroplating said metal contacts that are held in said at least one said contact material strip; (g) inserting the mating contact portions of each set of said metal contacts at said at least one contact material strip and a part of the mounting portions of the respective said metal contacts into one respective cavity of a molding mold, and then using an insert molding technique to mold one respective electrically insulative terminal block on each set of said metal contacts; (h) removing said molding mold, and then inserting each set of said metal contacts with the respective said electrically insulative terminal block through a rear insertion hole of one respective electrically insulative housing into a front receiving chamber of the respective said electrically insulative housing to force respective retaining protrusions of the respective said electrically insulative terminal block into engagement with respective retaining grooves in said rear insertion hole of the respective said electrically insulative housing.
