Test and connection apparatus arrangement, and test apparatus

摘要

A testing arrangement for testing the electrical circuits of a terminal block assembly, comprising a generally rectangular testing unit housing formed of insulating material and containing a chamber, at least one connection device mounted in chamber and having an elongated connector body formed of insulating material and including center and end portions. An integral measuring tab portion extends downwardly from the body center portion for insertion into a testing opening contained in the terminal block assembly, and a pair of coplanar measurement portions extend upwardly from the connector body ends and terminating at different elevations, thereby to afford a compact testing arrangement. Two electrical circuit connecting portions are mounted on the connector body, each including an input conductive contact plate mounted on one side of said measuring tab portion, and an output contact mounted within one of said measurement portions for connection with one end of a testing component.

主权项

1. A testing arrangement for testing the electrical circuits of a terminal block assembly (3), comprising at least one testing unit (200) including:
(a) a generally rectangular testing unit housing (23) formed of insulating material, said housing including vertical pairs of side and end walls, and horizontal top and bottom walls, said walls defining a chamber contained within said housing; (b) at least one connection device (42) mounted in said housing chamber, said connection device including:
(1) an elongated connector body formed of insulating material and having center and end portions, said connector body including:
(a) an integral measuring tab portion (24) extending downwardly from said connector body center portion, and outwardly from said testing unit housing via an opening contained in said housing bottom wall, said tab portion being adapted for insertion into a testing opening contained in the terminal block assembly;(b) a pair of coplanar measurement portions (29) extending upwardly from said connector body end portions, respectively, via corresponding openings contained in said testing unit housing; and(2) a testing circuit at least partially mounted on said connection device, said testing circuit including:
(a) an electrical testing component (33) having a pair of end terminals;(b) a pair of input conductive contact plates (24c, 24d) mounted on opposite sides of said measuring tab portion for connection with the terminals of an electrical circuit of said terminal block assembly that is to be tested; and(c) a pair of conductive connecting paths connecting said contact plates with said testing component end terminals, respectively, each of said conductive arrangements including a bus bar section arranged within said elongated connector body, and a contact carried by an associated one of said measurement portions; (c) said measurement portions terminating in upper tip portions (291) that are at different elevations relative to each other, thereby to afford a compact assembly of said testing arrangement.
