Electrical connector having front or rear releasable and removable contacts

Claim 2

In combination with an electrical connector having front and rear releasable and rear removable contacts, said connector of the type having: a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an enlarged middle portion having a forwardly facing shoulder and a rearwardly facing shoulder; and means for releasably mounting said contacts in said housing including a rear insert having a plurality of bores each having the rear portion of a respective contact therein, a plurality of resiliently and radially deflectable members extending from the forward portion of each of said bores, and a forward insert having a plurality of bores each having a portion of the forward portion of a respective contact therein, and a rearwardly facing surface adapted to engage the forwardly facing shoulder of each of said contacts, the improvement wherein: each of said members of said rear insert, includes at the forward end of said member a radially inwardly chamfered surface and, rearwardly adjacent to the chamfered surface, a forwardly facing shoulder engaging the rearwardly facing shoulder of a respective contact; and said forward insert includes a plurality of passages annularly arranged around each of said bores, each of its passages axially aligned with a respective forwardly facing shoulder of the deflectable members of said rear insert, whereby a tool may be inserted into the passages to engage and radially deflect said deflectable members at the end of that passage thereby releasing the contact for removal from the rear of the connector.

Claim 3

In combination with an electrical connector having front and rear releasable rear removable contacts, said connector of the type having: a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an enlarged middle portion having a forwardly facing shoulder and a rearwardly facing shoulder, and means for releasably mounting said contacts in said housing including an insert having a plurality of bores each having a portion of a respective contact therein, a plurality of resiliently and radially deflectable members extending forwardly in the direction of said enlarged middle portion of said contacts and a rearwardly facing shoulder in each of said bores adapted to engage the forwardly facing shoulder of a respective contact, the improvement wherein: each of said members includes at the forward end of said member a radially inwardly chamfered surface and, rearwardly adjacent to the chamfered surface, a forwardly facing shoulder engaging the rearwardly facing shoulder of a respective contact; and a second plurality of passages annularly arranged around each of said bores and extending rearwardly from the front of said insert, each of said passages axially aligned with a respective forwardly facing shoulder of the deflectable members, whereby a tool may be inserted into the passages to engage and radially deflect said deflectable members at the end of that passage thereby releasing the contact for removal from the rear of the connector.

Claim 4

In combination with an electrical connector having front and rear releasable rear removable contacts, said connector of the type having: a housing; a plurality of contacts, each contact having a rear portion, a forward mating portion, and an enlarged middle portion having a forwardly facing shoulder and a rearwardly facing shoulder, and means for releasably mounting said contacts in said housing including an insert having a plurality of bores each having a portion of a respective contact therein, a plurality of resiliently and radially deflectable members extending forwardly in the direction of said enlarged middle portion of said contacts and a rearwardly facing shoulder in each of said bores adapted to engage the forwardly facing shoulder of a respective contact, the improvement wherein: each of said members includes at the forward end of said member a radially inwardly chamfered surface and, rearwardly adjacent to the chamfered surface, a forwardly facing shoulder engaging the rearwardly facing shoulder of a respective contact; and a second plurality of passages annularly arranged around each of said bores and extending rearwardly from the front of said insert, each of said passages axially aligned with a respective forwardly facing shoulder of the deflectable members, whereby a tool may be inserted into the passages to engage and radially deflect said deflectable members at the end of that passage thereby releasing the contact for removal from the rear of the connector.

Claim 5

In combination with an electrical connector having removable contacts, said connector of the type having: a housing; a plurality of cylindrical contacts, each contact having a rear portion, a forward mating portion, and an enlarged middle portion having a forwardly facing shoulder and a rearwardly facing shoulder; and means for releasably mounting said contacts in said housing including a rear insert having a plurality of bores each having the rear portion of a respective contact therein, a plurality of resiliently and radially deflectable members extending from the forward position of each of said bores, and a forward insert having a plurality of bores each having a portion of the forward portion of a respective contact therein, and a rearwardly facing surface adapted to engage the forwardly facing shoulder of each of said contacts, the improvement wherein: each of said members of said rear insert, includes at the forward end of said member a radially inwardly chamfered surface and, rearwardly adjacent to the chamfered surface, a forwardly facing shoulder engaging the rearwardly facing shoulder of a respective contact; and said forward insert includes a plurality of passages annularly arranged around each of said bores, each of its passages axially aligned with a respective forwardly facing shoulder of the deflectable members of said rear insert, whereby a tool may be inserted into one of said bores in the rear insert and said plurality of passages around a bore in the front insert to engage and radially deflect said deflectable members thereby releasing the contact for removal from the rear of the connector.

Claim 6

In combination with an electrical connector having removable contacts, said connector of the type having: a housing; a plurality of cylindrical contacts, each contact having a rear portion, a forward mating portion, and an enlarged middle portion having a forwardly facing shoulder and a rearwardly facing shoulder; and means for releasably mounting said contacts in said housing including a rear insert having a plurality of bores each having the rear portion of a respective contact therein, a plurality of resiliently and radially deflectable members extending from the forward position of each of said bores, and a forward insert having a plurality of bores each having a portion of the forward portion of a respective contact therein, and a rearwardly facing surface adapted to engage the forwardly facing shoulder of each of said contacts, the improvement wherein: each of said members of said rear insert, includes at the forward end of said member a radially inwardly chamfered surface and, rearwardly adjacent to the chamfered surface, a forwardly facing shoulder engaging the rearwardly facing shoulder of a respective contact; and said forward insert includes a plurality of passages annularly arranged around each of said bores, each of its passages axially aligned with a respective forwardly facing shoulder of the deflectable members of said rear insert, whereby a tool may be inserted into one of said bores in the rear insert and said plurality of passages around a bore in the front insert to engage and radially deflect said deflectable members thereby releasing the contact for removal from the rear of the connector.
