HDMI plug and cable assembly with improved retention features
High-definition multimedia interface (HDMI) plugs are modified to include one or more retention features that increase the force needed to extract a fully inserted HDMI plug from a compatible mating receptacle. In several embodiments, a high-definition multimedia interface (HDMI) plug includes a connector body having a mating end configured for insertion in a longitudinal direction into a mating HDMI receptacle and having a slot-shaped opening along at least one wall of the connector body, extending in the longitudinal direction. A movable tab is biased to extend outward from the slot-shaped opening in a first position, when unconstrained by the mating HDMI receptacle, and configured to retreat into a second position, substantially within said opening, when longitudinally engaged by a leading edge of the mating HDMI receptacle during insertion of the connector body. Additional retention features and mating HDMI receptacles are also described.
1. A high-definition multimedia interface (HDMI) plug comprising:
a connector body having a mating end configured for insertion in a longitudinal direction into a mating HDMI receptacle and having a first slot-shaped opening in a wall of said connector body, extending in the longitudinal direction; and
a first movable tab biased to extend outward from the first slot-shaped opening in a first position, when unconstrained by the mating HDMI receptacle, and configured to retreat into a second position, substantially within said opening, when longitudinally engaged by a leading edge of the mating HDMI receptacle during insertion of the connector body therein;
wherein the connector body comprises a first face having a first width, a second face opposite the first face and having a second width greater than the first width, and two ledge portions at first and second sides of the connector body, running in the longitudinal direction, each ledge portion forming a transition between the first width and the second width, and wherein the first slot-shaped opening is disposed on one of the ledge portions so that the first movable tab extends outward towards the first face when in the first position.
2. The HDMI plug of claim 1 , further comprising:
a second slot-shaped opening in a wall of said connector body, extending in the longitudinal direction;
and a second movable tab spring-biased to extend outward from the second slot-shaped opening when unconstrained by the mating HDMI receptacle, and configured to retreat into an position substantially within the second slot-shaped opening when longitudinally engaged by the leading edge of the mating HDMI receptacle during insertion of the connector body therein;
wherein the second slot-shaped opening is disposed on a second one of the ledge portions so that the second movable tab extends outward towards the first face when unconstrained by the mating HDMI receptacle.
3. The HDMI plug of claim 1 , wherein the first movable tab has a forward edge configured to engage a leading edge of the mating HDMI receptacle during insertion of the connector body therein, wherein said forward edge is disposed at an obtuse angle relative to a ray extending from the first movable tab towards the mating end of the connector body, in the longitudinal direction.
4. The HDMI plug of claim 3 , wherein the first movable tab has a trailing edge configured to engage an opening in the mating HDMI receptacle during retraction of the connector body therefrom, wherein said trailing edge is disposed at an obtuse angle relative to a ray extending from the first movable tab away from the mating end of the connector body, along the longitudinal axis.
5. The HDMI plug of claim 1 , wherein the connector body further comprises a first opening in the first face, the first opening sized and located to accept a first spring-biased tab of the mating HDMI receptacle upon insertion of the connector body therein.
6. The HDMI plug of claim 1 , wherein the connector body further comprises a second opening in the second face, the second opening sized and located to accept a second spring-biased tab of the mating HDMI receptacle upon insertion of the connector body therein.
