Definitions
- ABSTRACT An electrical connector having a built-in tool for removing electrical contacts from the connector for maintenance and/or repair.
- Each of the contacts of the Connector includes a movable bushing mounted thereon which is operable to release the contact from the connector insert.
- the configuration of the Contact includes an annular groove that provides more secure retention of the Contact.
- the configuration of the built-in tool includes one or more outwardly extending fingers that prevents inadvertent movement of the tool to a position that would release the contact from its secured position.
- U.S. Pat. No. 3,221,292 entitled Electrical Connector, issued Nov. 3, 1965 to G. .l. Swanson et al. illustrates a multi-pin electrical connector of the type associated with this invention.
- One of the problems associated with multi-pin electrical connectors of the type that have removable contacts and a contact removable tool mounted thereon is that the removable tool is sometimes inadvertently moved into a position that allows the contact to be released. This is most undesirable because electrical continuity is lost between two terminals that should have been mated.
- Another disadvantage of these type connectors is that the retention members that retain the contacts do not extend inwardly a sufficient distance to adequately secure the contact against movement when a small amount of axial force is applied.
- This invention provides a contact retention and removal assembly that provides greater retention of the electrical contact once secured in the connector insert and provides a mechanism for avoiding the inadvertent operation of the built-in contact removal tool.
- the invention is a contact retention and removal assembly for a multi-pin electrical connector characterized by a contact removal bushing (40) that includes one or more fingers (41) that extend outwardly with respect to the axis of the bushing to prevent the removal bushing from entering the insert passage unless an axial force of predetermined amount is applied; and
- an electrical contact (30) that includes an annular groove (33) behind the retention shoulder (32) so that the retention member (21) deflects radially inwardly a greater distance than would be accomplished without the groove (33), whereby more secure retention of the contact (30) is obtained.
- the invention is described as a contact retention and removal assembly for a multi-pin electrical connector of the typehaving a dielectric insert (10) having axially aligned contact receiving passages extending from a first face (11) of the insert to a second opposite face (12); each of the passages having an enlarged passage portion forming at the junction thereof an internal shoulder (13) facing the second face, 12), the assembly comprising: a contact retention bushing mounted in the enlarged passage portion of each of the passages, the bushing having at least one radially deflectable member (21) that extends inwardly with respect to the axis of said bore in a direction towards the insert first face (11); a contact mounted in each of the bushings (4.0), each of the contacts (30) having an enlarged section forming a first shoulder (31) that faces in the direction of the first face (11) and engages the internal shoulder (13) in the passage to prevent further movement of a contact toward the first face (11) and a second shoulder (32) that faces in the direction of the second face (12)
- FIG. 1 is a cross-sectional view of the contact retention and removal assembly with the removal tool in its normal position.
- FIG. 2 is a cross-sectional view of the contact retention and removal assembly illustrating the removal tool in its inserted position and the contact in its partially withdrawn position.
- FIG. 1 illustrates one embodiment of the invention, that includes an electrical connector dielectric insert a contact retaining mechanism an electrical contact (30), and a captivated removal bushing (40).
- the dielectric insert includes a bore that extends from a first face (11) to an opposite second face (12).
- a retention mechanism (20) Disposed within the passage of the insert (10) is a retention mechanism (20) which generally includes one or more radially deflectable fingers or members (21) that extends inwardly with respect to the axis of the insert bore. These reflectable retention members (21) cooperate with a shoulder (32) on the contact 30) to prevent movement of the contact (30) in the direction of the second face (12). Passage in the insert further includes means for stopping the movement of the contact (30), in the direction away from said second face (12), at a predetermined point.
- the stop means comprises an internal shoulder 13) that engages a shoulder (31) of the contact (30) to prevent further movement of the contact (30) in a direction away from the second face (12).
- the electrical contact (30) includes an enlarged portion that forms a first shoulder (31) and an oppositely facing second shoulder (32).
- the first shoulder (31) faces in the direction of the insert first face (11) and the second shoulder (32) faces away from the first face (11) and in the direction of the second face (12).
- the first shoulder (31) is adapted to engage the insert shoulder (13) within the passage to prevent further movement of the contact (30) in the direction towards the first face (11).
- the second shoulder(32) is adapted to engage the radially deflecting retention member (21) to prevent movement of the electrical contact (30) in the direction of the insert second face (12).
- the contact first shoulder (31) and second shoulder (32) together with the insert shoulder (13) and retention member 21) operate to captivate the electrical contact (30) in a predetermined position within the electrical connector insert (10).
- annular groove (33) Immediately adjacent the enlarged portion of the contact is an annular groove (33) that allows the retention member (21) to deflect inwardly a greater distance than would be accomplished without the groove (33) whereby a more secure retention of the contact is obtained.
- the remaining end portion (36) of the contact is adapted to receive an electrical conductor (not shown) at one end by either soldering or by the ferrule (50).
- the end portion (36) is also adapted to slidably support the removal tool (40).
- the removal bushing (40) is mounted around the end portion (36) of the contact (30) and includes a radially 6 extending flange (44) that facilitates the application of an axial force, in either direction, applied to the removal bushing (40).
- the forward portion of the removal bushing (40) is generally comprised of a tubular member that includes one or more outwardly extending fingers (41). It is the function of these outwardly extending fingers (41) to prevent inadvertent movement (caused by small axial forces) of the removal bushing (40) into a position that would disengage the retention fingers (21). Further, the extending fingers (41) give visual indication that the retaining fingers (21) are disengaged and the contact is not secured when the fingers (41) are not radially extended.
- the removal bushing (40) is captivated on the contact 30) by the contact second shoulder (32) and the ferrule which attaches an electrical conductor to the contact.
- FIG. 2 illustrates the contact removal bushing (40) in the inserted position and the radial deflection of the contact retention members (21) that allows withdrawal of the contact (30).
- the contact (30) is shown in a partially withdrawn position wherein the enlarged portion of the contact (30) is located in a position that does not permit the retention members (21) to engage the contact second shoulder (32) and prevent withdrawal of the contact (30) from the insert.
- the invention operates as follows.
- the retention members (21) engage the shoulder (32) to secure the contact in a position that does not allow movement of the contact in a direction of the second face (12) of the insert (10).
- an axial force is applied to the flange (44) of removal bushing (40) in the direction of the contact shoulder (32).
- the axial force moves the bushing (40) until it deflects the retention members (21) and then engages the shoulder (32).
- each of said contacts having an enlarged section forming a first shoulder that faces in the direction of said first face and engages said internal shoulder in said passage to prevent further movement of said contact toward said first face and a second shoulder that faces in the direction of said second face and engages said retention member to prevent movement of said contact in the direction of said second face, said contact further including an annular groove adjacent said second shoulder to receive said retention member and permit said retention member to deflect inwardly a greater distance than would be accomplished without said groove whereby more secure retention of said contact is obtained;
- each of said bushings including at least one deflectable member extending outwardly of the cylinder of the removal bushing in a direction away from said contact second shoulder, said deflectable member of said bushing located to engage a wall of said passage before said removal bushing engages the said deflectable member of said retention bushing, preventing said removal bushing from completely entering said passage until sufficient axial force is applied to deflect inwardly said deflectable members, said removal bushing being movable in the direction of said second shoulder by an axial force applied to said removal bushing in the direction of said first face whereby when such force is applied to said removal bushing, said removal bushing deflects said retention members out of engagement with said contact second shoulder to permit withdrawal of said contact.
