Abstract
Abstract The disclosure relates to an electrical terminal for making electrical connection with a square post or the like within a housing, the housing having a cavity of slightly larger dimension than the normal dimension of the connector spring fingers. The housing includes a pair of shoulders on which hooks or projections at the end of the terminal spring fingers lock upon complete insertion of the terminal within the housing. One spring finger includes teeth thereon and the other spring finger includes a tooth mateable with the teeth on the first finger in order to allow both fingers to be pushed together to a great degree. The terminal is designed so that the innermost portion of one of the spring fingers is spaced from the innermost portion of the other of the spring fingers by an amount less than the crosssectional area of the square post terminal to be inserted therein so that the projections or hooks will be locked firmly on the shoulders upon insertion of the square post.

A multi-contact electrical connector for forming disengageable electrical connections to a row of spaced-apart rigid terminal posts, said posts being mounted in, and extending from, a panel board or the like, said connector comprising: a generally prismatic housing having a rearward face and a mating face, a plurality of contact-receiving cavities extending through said housing from said rearward face towards said mating face, said cavities having inner ends which are proximate to said mating face, said cavities having laterally extending branches at said inner ends said branches opening onto the side edges of said mating face and opening onto the sides of said housing which are on each side of said mating face, said branches defining shoulders directed towards said mating face, a plurality of windows in said mating face, each of said windows communicating with, and being centrally located with respect to, one of said cavities, a fork-type electrical contact terminal in each of said cavities, each of said terminals comprising a stamped member having a yoke portion and a pair of co-planar arms extending from said yoke portion, said arms having oppositely directed hook portions on their free ends, said hook portions extending into said branches and being latched against said shoulders to prevent rearward movement of said terminal from said cavity, and each of said terminals being disposed against the rearwardly facing sides of one of said windows to prevent forward movement of said terminal through said cavity, one of said arms having a single tooth and the other one of said arms having two teeth, said single tooth being between said two teeth, said teeth having contact crown portions, said contact crown portions being spaced apart on opposite sides of said window and being adapted to engage a contact post extending through each window.

A multi-contact electrical connector for forming disengageable electrical connections to a row of spaced-apart rigid terminal posts, said posts being mounted in, and extending from, a panel board or the like, said connector comprising: a generally prismatic housing having a rearward face and a mating face, a plurality of contact-receiving cavities extending through said housing from said rearward face towards said mating face, said cavities having inner ends which are proximate to said mating face, said cavities having laterally extending branches at said inner ends said branches opening onto the side edges of said mating face and opening onto the sides of said housing which are on each side of said mating face, said branches defining shoulders directed towards said mating face, a plurality of windows in said mating face, each of said windows communicating with, and being centrally located with respect to, one of said cavities, a fork-type electrical contact terminal in each of said cavities, each of said terminals comprising a stamped member having a yoke portion and a pair of co-planar arms extending from said yoke portion, said arms having oppositely directed hook portions on their free ends, said hook portions extending into said branches and being latched against said shoulders to prevent rearward movement of said terminal from said cavity, and each of said terminals being disposed against the rearwardly facing sides of one of said windows to prevent forward movement of said terminal through said cavity, one of said arms having a single tooth and the other one of said arms having two teeth, said single tooth being between said two teeth, said teeth having contact crown portions, said contact crown portions being spaced apart on opposite sides of said window and being adapted to engage a contact post extending through each window.
