Abstract
Abstract A surface mount connector in which contacts mounted in two or more rows of contact passages have tails bent so that their end portions lie in a common plane for engaging traces on a printed circuit board. Each contact is a two piece part. The two parts are mounted in the corresponding contact passage from the opposite end faces of the insulator, so that the tails may be bent during the forming of the rear parts of the contacts rather than after mounting of the contacts in the passages. A retention arrangement is provided between the front and rear parts of the contacts which allows either a permanent connection between the parts, or a releasable connection so that the front and rear parts of the contacts may be removed from the passages and replaced if necessary.

Total Claims: 11
Claim 1
Independent Claim
216 words
An electrical connector comprising: an insulator having a front face and a rear face with at least one contact passage extending therethrough opening at said faces; a contact mounted in said passage, said contact having a forward mating section and a rear termination section; said forward section of said contact being mounted in said passage from said front face; said rear section of said contact being mounted in said passage from said rear face; said forward section of said contact having a mating portion adjacent to said front face and a rear portion adjacent to said rear face; said rear section of said contact embodying a generally tubular forward portion surrounding said rear portion of said front section of said contact, said tubular portion being slidably mounted in said passage; said rear portion of said forward section of said contact embodying a generally forwardly facing shoulder; means connecting said rear section of said contact to said rear portion of said front section of said contact, said connecting means comprising a radially movable resilient finger extending inwardly and rearwardly from said tubular portion with its end engaging shoulder; means restricting axial movement of said contact in said passage; and said rear section of said contact embodying a terminal extending rearwardly from said rear face of said insulator.
Claim 2
Dependent Claim
