Cable end retention clip
View Patent ↗A connector assembly is provided having a cable end plug with a body adapted to be connected to a cable with a connector part, and at least one outwardly extending flange on the body. A mating receptacle receives the cable end plug. The receptacle has a body with a complementary connector part to the cable end plug connector part. A retention clip is connected to the receptacle body, and includes at least one spring arm extending outwardly therefrom with a distal entry ramp portion, a retaining shoulder portion and a flange receiving portion. A thickness of the flange is approximately equal to a depth of the flange receiving portion so that the retaining shoulder portion engages behind the flange in a connected position of the cable end plug in the mating receptacle. For release, the retaining shoulder can be set at an angle of at least 94° to the flange receiving portion to form a release ramp that allows disengagement when a sufficiently high predetermined release force is applied to the cable end plug. Alternatively, the retaining shoulder is set at about 90° and ejector tabs are provided on the cable end plug to disengage the spring arms.
1. A connector assembly, comprising:
a cable end plug having a body adapted to be connected to a cable with a connector part, and at least one outwardly extending flange on the body, the flange having a thickness;
a mating receptacle that receives the cable end plug, the receptacle having body with a complementary connector part to the cable end plug connector part, and a retention clip connected to the receptacle body, the retention clip including at least one spring arm extending outwardly therefrom with a distal entry ramp portion, a retaining shoulder portion and a flange receiving portion, wherein a thickness of the flange is approximately equal to a depth of the flange receiving portion so that the retaining shoulder portion engages behind the flange in a connected position of the cable end plug in the mating receptacle;
further comprising guide posts extending from the receptacle body, the retention clip including complementary openings to the guide posts and being located over the guide posts in a position against the receptacle body, and retainers being located on the guide posts that hold the retention clip against the receptacle body.
2. The connector assembly of claim 1 , wherein the retaining shoulder portion has a length that is less than or equal to a distance which the flange protrudes from the body of the cable end plug.
3. The connector assembly of claim 1 , wherein there are two of the outwardly extending flanges on the cable end plug located on opposite sides of the body, and there are two of the spring arms, each engaging a respective one of the flanges in the connected position.
4. The connector assembly of claim 1 , wherein the retaining shoulder portion of the at least one spring arm is set at an angle of at least 94° with respect to the flange receiving portion, forming a release ramp such that the at least one spring arm is automatically deflected outwardly and over the at least one flange upon application of a release force on the cable end plug in a direction away from the receptacle.
5. The connector assembly of claim 4 , wherein the angle is between 94° and 95°.
6. The connector assembly of claim 1 , wherein the retention clip is formed of a bent-up sheet metal part.
7. A connector assembly, comprising:
a cable end plug having a body adapted to be connected to a cable with a connector part, and at least one outwardly extending flange on the body, the flange having a thickness;
a mating receptacle that receives the cable end plug, the receptacle having body with a complementary connector part to the cable end plug connector part, and a retention clip connected to the receptacle body, the retention clip including at least one spring arm extending outwardly therefrom with a distal entry ramp portion, a retaining shoulder portion and a flange receiving portion, wherein a thickness of the flange is approximately equal to a depth of the flange receiving portion so that the retaining shoulder portion engages behind the flange in a connected position of the cable end plug in the mating receptacle;
wherein the retaining shoulder portion of the at least one spring arm is set at an angle of about 90° with respect to the cable end plug flange receiving portion, and the cable end plug body including at least one ejector tab that is displaceable on the cable end plug body to engage and deflect the at least one spring arm outwardly and over the at least one flange upon application of a pressing force on the ejector tab in conjunction with an oppositely directed release force on the cable end plug in a direction away from the receptacle.
8. The connector assembly of claim 7 , wherein there are two of the spring arms, one located opposite the other on the receptacle, there are two of the flanges located in complementary positions on the cable end plug body, and there are two of the ejector tabs, each being located in a complementary position to one of the spring arms, and the ejector tabs are displaceable on the cable end plug body to engage and deflect the two spring arms outwardly and over the two flanges upon application of a pressing force on the two ejector tabs in conjunction with an oppositely directed release force on the cable end plug in a direction away from the receptacle.
9. The connector assembly of claim 8 , wherein the ejector tabs are slideably displaceable.
10. The connector assembly of claim 7 , wherein the ejector tab includes a cylindrical-shaped end protrusion that is adapted to engage the spring arm.
11. The connector assembly of claim 7 , wherein the receptacle body includes a slide channel defined by two channel sides, and the at least one ejector tab is slidable in the slide channel and includes a retaining clip that engages in a recess in one of the channel sides.
