Abstract
Abstract An electrical connector adapted to even more securely and positively hold a conventional terminal element therein such that the terminal element cannot be withdrawn from a main body portion of the connector by a pulling or tugging force. The connector comprises a main body portion having an inner upper wall portion and an inner lower wall portion. A plurality of upper bores are formed in connection with the inner upper wall portion, and a plurality of lower bores are formed in connection with the inner lower wall portion. Each of the inner upper and lower wall portions include a shoulder portion which protrudes into one of the upper or lower bores. A conventional terminal element is inserted into a front side of the connector where a portion of the terminal element abuttingly engages the internal shoulder portion of the bore in which it is inserted. A shoulder portion positively and effectively prevents the terminal element from being withdrawn by a pulling or tugging force from a rear side of the main body portion. The upper and lower shoulder portions are non-flexible and non-moving and are therefore not susceptible to breakage such as with conventional leaf beam-type latching arms.

Claim 1
Independent Claim
330 words
An electrical connector comprising: a main body portion having a front side, a rear side, an inner upper wall portion and an inner lower wall portion; a first plurality of bores formed in part from said inner upper wall portion; a second plurality of bores formed in part from said inner lower wall portion; said inner upper wall portion including a plurality of non-flexible, non-movable, internal upper shoulder portions, with each one of said internal upper shoulder portions protruding into an associated one of said bores of said upper row of bores; said inner lower wall portion including a plurality of non-flexible, non-movable internal lower shoulder portions, each one of said lower shoulder portions protruding into an associated one of said bores of said lower row of bores; each bore of said upper and lower rows of bores being adapted to slidably receive therein a terminal element inserted therein from said front side of said main body portion; each one of said internal shoulder portions being adapted to engage a portion of an associated one of said terminal elements inserted within its associated bore to thereby prevent said terminal element from being pulled from said rear side of main body portion out of said main body portion wherein said inner upper wall portion includes a plurality of upper rib portions, with each one of said upper rib portions protruding into an associated one of said bores; wherein said inner lower wall portion includes a plurality of lower rib portions, with each one of said lower rib portions protruding into an associated one of said bores of said lower row of bores; each one of said upper and lower rib portions being operable to help facilitate electrical connection between a terminal element inserted within each one of said bores and a terminal member protruding into an associated one of said bores by forcing said terminal member into electrical contact with said terminal element inserted within said associated one of said bores.
Claim 2
Dependent Claim
330 words
An electrical connector comprising: a main body portion having a front side, a rear side, an inner upper wall portion and an inner lower wall portion; a first plurality of bores formed in part from said inner upper wall portion; a second plurality of bores formed in part from said inner lower wall portion; said inner upper wall portion including a plurality of non-flexible, non-movable, internal upper shoulder portions, with each one of said internal upper shoulder portions protruding into an associated one of said bores of said upper row of bores; said inner lower wall portion including a plurality of non-flexible, non-movable internal lower shoulder portions, each one of said lower shoulder portions protruding into an associated one of said bores of said lower row of bores; each bore of said upper and lower rows of bores being adapted to slidably receive therein a terminal element inserted therein from said front side of said main body portion; each one of said internal shoulder portions being adapted to engage a portion of an associated one of said terminal elements inserted within its associated bore to thereby prevent said terminal element from being pulled from said rear side of main body portion out of said main body portion wherein said inner upper wall portion includes a plurality of upper rib portions, with each one of said upper rib portions protruding into an associated one of said bores; wherein said inner lower wall portion includes a plurality of lower rib portions, with each one of said lower rib portions protruding into an associated one of said bores of said lower row of bores; each one of said upper and lower rib portions being operable to help facilitate electrical connection between a terminal element inserted within each one of said bores and a terminal member protruding into an associated one of said bores by forcing said terminal member into electrical contact with said terminal element inserted within said associated one of said bores.
Claim 3
Dependent Claim
376 words
An electrical connector comprising: a main body portion having a front side, a rear side, an integrally formed inner upper wall portion, and an integrally formed inner lower wall portion; said inner upper wall portion partially defining a plurality of upper bores formed in an upper row; said inner lower wall portion helping to define a plurality of lower bores formed in a lower row; said inner upper wall portion including a plurality of inflexible, non-movable internal shoulder portions integrally formed therewith, each protruding into an associated one of said upper bores; said inner lower wall portion including a plurality of inflexible, unmovable internal lower shoulder portions integrally formed therewith, each protruding into an associated one of said lower bores of said lower row of bores; a plurality of terminal elements inserted within said upper and lower bores from said front side of said main body portion, said upper and lower internal shoulder portions operating to abuttingly engage a portion of each of said terminal elements to prevent each of said terminal elements from being withdrawn from said main body portion out of said rear side of said main body portion; a front cover portion adapted to be secured over said front side of said main body portion to maintain said terminal elements within said upper and lower bores, said front cover portion including a plurality of apertures forming an upper row and a lower row, each one of said apertures being positioned in longitudinal alignment with an associated one of said bores such that a terminal member inserted through any one of said apertures engages an associated one of said terminal elements housed within one of said bores wherein said inner upper wall portion includes a plurality of upper rib portions, with each one of said upper rib portions protruding into an associated one of said bores; wherein said inner lower wall portion includes a plurality of lower rib portions, each one of said lower rib portions protruding into an associated one of said bores; and each one of said upper and lower rib portions operating to urge a terminal member into engagement with a terminal element inserted within its associated bore, to thereby ensure electrical contact between said terminal member and said terminal element.
Claim 4
