Embodiment Construction

[0027] Referring to the attached drawings for details, figure 1 Denotes a blank, generally indicated at 10, which has been stamped or molded from a continuous sheet metal material or strip of metal material in an initial step of the manufacturing method of the present invention. The stamping process removes the metallic material, leaving an outline comprising a number of elongated branch bars 12 which will eventually be formed into the contact portions of the elongated terminals. These terminals will comprise at their opposite ends terminal portions formed from a continuous blank 14 of sheet metal material. A continuous connecting strip 16 connects these branch strips 12 . The continuous support edge 18 is connected to the continuous bad 14 via fingers 20 . The fingers 20 are substantially in line with the branch bar 12 . A row of indexing holes 22 are punched into the support edge 18, as is known in the art, to facilitate movement of the blank through subsequent stations ...

Abstract

A method of manufacturing electrical terminals and / or a terminal module (36) is disclosed. The method includes the steps of stamping from a sheet of metal material a blank (10) for a plurality of elongated terminals having contact portions (30) at one end and terminal portions (28a,28b) at the other end and joining the terminals by a tie bar (16) intermediate the ends. The contact portions (30) of the respective terminals are separated from each other by the stamping step. The terminal portions (28a,28b) remain joined in the sheet of metal after the stamping step. The blank then is sheared to separate the terminal portions (28a,28b). The tie bar (16) is cut to separate the terminals. In order to form a terminal module (36), a dielectric housing (34) is overmolded about the terminals intermediate the ends thereof, with the tie bar (16) being located outside the housing and removed after the overmolding process.

Description

technical field [0001] This invention relates generally to electrical connectors, and more particularly to the terminals of such connectors. More particularly, the present invention relates to a method of making or assembling electrical terminals, including terminals for use in terminal modules. Background technique [0002] A typical electrical connector includes an insulating or dielectric housing housing a number of terminals. These connectors are matable with complementary mating connectors or other connection means, wherein the terminals engage or mate with the ends of the complementary connector. [0003] It is well known in the art to manufacture terminals for electrical connectors from a continuous sheet or strip of metallic material by stamping and forming the terminals. During a stamping or punching operation, portions of the sheet metal material are cut away, leaving contours of the terminals which are substantially formed into the desired configuration. These ...
