Retention member for connector system
View Patent ↗A retention member aligns and stabilizes one or more insert molded lead assemblies (IMLAs) in an electrical connector. The retention member provides for alignment and stability in the x-, y-, and z-directions. Such a retention member may be in connection with a right angle header connector. The retention member provides stability by maintaining the true positioning of the terminal ends of the contacts. The retention member is expandable in length, and may be sized and shaped to fit a single header assembly or multiple position configurations.
1. An electrical connector comprising:
a connector housing;
a lead assembly comprising a mating end that extends into the housing in a mating direction; and
a lead assembly retainer comprising a plurality of retention surfaces that prevent the lead assembly from moving in at least one direction,
wherein the lead assembly further comprises a biasing member that biases the retainer in the mating direction.
2. The electrical connector of claim 1 , wherein the lead assembly further comprises an arm portion that extends over the retainer and prevents the lead assembly from moving in the mating direction relative to adjacent lead assemblies of the electrical connector.
3. The electrical connector of claim 1 , wherein the retainer prevents the lead assembly from moving in a direction opposite the mating direction.
4. The electrical connector of claim 1 , wherein the connector housing comprises a mechanical stop, and the lead assembly abuts the mechanical stop such that the mechanical stop prevents the lead assembly from moving in the mating direction.
5. The electrical connector of claim 1 , wherein the connector housing comprises first and second dividing walls, the lead assembly is disposed between the dividing walls, and the dividing walls are spaced apart by a distance that is small enough to prevent the lead assembly from moving in the mating direction.
6. The electrical connector of claim 5 , wherein at least one of said first and second dividing walls comprises a notch, and the lead assembly comprises a protrusion that is received into the notch and prevents the lead assembly from moving in a direction opposite the mating direction.
7. The electrical connector of claim 6 , wherein the protrusion has a ramped configuration.
8. The electrical connector of claim 6 , wherein the protrusion has a triangular cross-section.
9. The electrical connector of claim 6 , wherein the protrusion has a trapezoidal cross-section.
10. An electrical connector comprising:
a connector housing comprising first and second dividing walls, each said dividing wall defining a respective notch, said notches disposed in a staggered relationship to one another;
a first lead assembly received in the connector housing in a mating direction, the first lead assembly comprising a first protrusion that is received into the notch in the first dividing wall and prevents the first lead assembly from moving in a direction opposite the mating direction; and
a second lead assembly comprising a second protrusion that is received into the notch in the second dividing wall and prevents the second lead assembly from moving in a direction opposite the mating direction.
11. The electrical connector of claim 10 , wherein the dividing walls are spaced apart by a distance that is small enough to prevent the first lead assembly from moving in the mating direction.
12. The electrical connector of claim 10 , wherein the first protrusion has a ramped configuration.
13. The electrical connector of claim 10 , wherein the first protrusion has a triangular cross-section.
14. The electrical connector of claim 10 , wherein the first protrusion has a trapezoidal cross-section.
15. The electrical connector of claim 10 , wherein the first protrusion has a rounded end.
16. An electrical connector, comprising:
a connector housing;
a lead assembly comprising a mating end that extends into the housing in a mating direction and a tab that extends from the lead assembly in a direction opposite from the mating direction;
a retainer for retaining the lead assembly in the electrical connector, the retainer comprising a wall portion having a first side and an opposite second side,
wherein the lead assembly is positioned adjacent to the first side of the retainer and the tab extends over the opposite second side of the retainer.
17. The electrical connector of claim 16 , wherein the tab is resilient.
