Problems solved by technology

Increasing the ampacity of these connector designs is typically achieved by increasing the number of beams to increase the number of contact points, which would result in an undesired increase in the size of the terminal assembly, making the resulting connector system more difficult to package in a vehicle

Embodiment Construction

[0035] Provided herein is an electrical connector capable of carrying currents in excess of 200 amperes, and in some cases in excess of 400 amperes. The present invention uses a contact insert with four mated contacts on each contact beam to increase the current carrying capacity of the connector. The electrical connector may also include a riveted joint to increase the rigidity of the terminal box without affecting the cable welding area.

[0036] figure 1A non-limiting example of a high current electrical connector 10 (hereinafter referred to as connector 10) is shown. Connectors 10 are shown in an unmated state to illustrate internal components, as will be described in more detail below. The connector 10 includes a female connector 12 having female electrical terminals 14 configured to receive male electrical terminals 16 disposed within a male connector 18. Male electrical terminal 16 may be a planar terminal having two exposed sides and be formed from a conductive mat...

Abstract

A high current electrical connector (10) includes a female electrical terminal (14) and a spring contact (32). The female electrical terminal (14) is configured to receive a male electrical terminal (16) and is formed from a single piece of electrically conductive material. A female electrical terminal (14) has a first side wall (20) and a second side wall (22). The second side wall (22) defines a distal end (26), a proximal end (28), and an intermediate region (30). The first side wall (20) is opposite and parallel to the distal end (26) of the second side wall (22). The spring contact (32) is formed from a single piece of conductive material disposed intermediate the first side wall (20) and the second side wall (22). The spring contact (32) defines a plurality of opposing pairs of contact beams (36). Each of the plurality of opposed pairs of contact beams (36) has a plurality of outer contact points (38) and a plurality of inner contact points (42). A plurality of outer contacts (38) contact the female electrical terminal (14) and a plurality of inner contacts (42) contact the opposite side of the male electrical terminal (16). Contact is made at least four separate locations between the contact beam (36), the female electrical terminal (14) and the male electrical terminal (16).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Patent Application No. 15 / 724,682, filed October 4, 2017, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates generally to electrical connectors, and more particularly to electrical connectors capable of carrying electrical current in excess of 200 amps. Background technique [0004] It is known to use electrical connectors capable of carrying over 100 amperes (100A) in electric vehicles (EV) and hybrid electric vehicles (HEV). As non-electric and non-hybrid vehicles increasingly become electrified to reduce greenhouse gases, electrical connectors require increasingly robust, reliable and safe designs. [0005] High current connectors have used twisted contact beams to increase the contact force between the male and female electrical terminals. These contact beams typically have only two co...
