Electrical connectors with electrical bonding features
Receptacles are provided for mating with plugs to establish electrical connections. The receptacles include a shell having a body, and a flange attached to the body. The flange has a projection extending therefrom. The receptacle also has an electrically-insulating insert positioned at least in part within the body; and one or more electrical contacts positioned at least in part within the insert. The receptacle is configured for mounting on a panel. The projection contacts a mounting surface of the panel, to establish a localized contact area that provides bonding between the receptacle and panel.
1. A receptacle for mating with a plug to establish an electrical connection, the receptacle comprising:
at least one electrical contact;
an electrically-insulating insert, wherein the at least one electrical contact is positioned at least in part within the insert; and
a shell configured for mounting on a substantially planar mounting surface; the shell comprising a body, and a flange attached to the body; wherein: the insert is positioned at least in part within the body; and the flange comprises a projection comprising a non-flexible rib configured to contact and deform the mounting surface when the receptacle is mounted.
2. The receptacle of claim 1 , wherein the rib is continuous.
3. The receptacle of claim 1 , wherein the rib has a substantially D-shaped cross section.
4. The receptacle of claim 1 , wherein the rib has a substantially triangular cross section.
5. The receptacle of claim 1 , wherein the rib has a substantially arcuate outer surface.
6. The receptacle of claim 1 , wherein the rib is disposed substantially symmetrically about a longitudinal centerline of the receptacle.
7. The receptacle of claim 1 , wherein the rib is ring shaped.
8. The receptacle of claim 1 , wherein the at least one electrical contact is a receptacle contact.
9. The receptacle of claim 1 , wherein the at least one electrical contact is a pin contact.
10. The receptacle of claim 1 , wherein the body and the flange of the shell are unitarily formed.
11. An electrical connector, comprising the receptacle of claim 1 , and a plug configured to mate with the receptacle to establish an electrical connection.
12. The receptacle of claim 1 , wherein: the mounting surface is a substantially planar surface of a panel; and the contact between the rib and the mounting surface electrically bonds the shell to the panel.
13. The receptacle of claim 12 , wherein the flange has a surface configured to face the panel when the receptacle is mounted on the panel; and the rib extends from the surface of the flange.
14. The receptacle of claim 13 , wherein the rib extends along a circular path on the surface.
15. The receptacle of claim 1 , wherein the rib has a width of about 0.025 inch to about 0.035 inch.
16. The receptacle of claim 15 , wherein the rib has a height of about 0.015 inch to about 0.025 inch.
17. A method for bonding a receptacle of an electrical connector to a panel, comprising:
providing a receptacle comprising: a shell comprising a body, and a flange attached to the body and comprising a projection, the projection comprising a non-flexible rib; an electrically-insulating insert positioned at least in part within the body; and at least one electrical contact positioned at least in part within the insert;
inserting a portion of the receptacle through an aperture in the panel so that the rib contacts a surface of the panel adjacent the aperture; and
securing the receptacle to the panel so that the rib deforms the surface of the panel.
18. The method of claim 17 , wherein securing the receptacle to the panel comprises fastening the flange to the panel so that a contact pressure between the rib and the surface of the panel is substantially uniform along the rib.
19. The method of claim 17 , wherein securing the receptacle to the panel comprises fastening the flange to the panel so that substantially all contact between the flange and the surface of the panel occurs by way of the rib.
