Compact interface module
View Patent ↗The invention pertains to a compact connector that accommodates a standard cable connector. By reducing the number of components at the interface, the invention allows a small form factor module to accommodate a cable connector that has thus been accommodated only by modules having larger dimensions. The device of the invention includes an electrically conductive lead protruding from a first outer surface of a connector housing and a shell disengageably coupled to the connector housing so as to form a cavity with the lead positioned therein, wherein the first outer surface forms an inner wall of the cavity. The invention also pertains to a module containing electrical components, including a lead, and a shell designed to hold a cable connector in contact with the lead. If the shell is made of a material that blocks electromagnetic radiation, the compact connector also serves as an EMI shield.
1. An electrical interface module device comprising:
an electrically conductive lead protruding from a first outer surface of a housing;
a shell disengageably coupled to the housing so as to form a cavity, wherein the lead is positioned in the cavity and wherein the first outer surface forms an inner wall of the cavity, and wherein the lead protrudes from a second outer surface of the housing;
electrical components electrically coupled to a portion of the lead protruding from the second outer surface; and
a bail that facilitates handling of the device, wherein the bail is adjustable between an operational position wherein the bail does not occupy the cavity and a release position wherein the bail occupies a part of the cavity.
2. The device of claim 1 wherein the shell is made of a material that shields electromagnetic radiation.
3. The device of claim 1 wherein the shell is made of an electrically nonconductive material.
4. The device of claim 1 further comprising gaps between the housing and the shell for accommodating the bail.
5. The device of claim 1 wherein the shell partially encloses the protruding lead, the housing, and the electrical components.
6. The device of claim 1 wherein the shell comprises an upper portion and a lower portion that combine to encapsulate the connector housing.
7. An electrical interface module device comprising:
an electrically conductive lead protruding from a first outer surface of a housing;
a shell disengageably coupled to the housing so as to form a cavity, wherein the lead is positioned in the cavity and wherein the first outer surface forms an inner wall of the cavity; and
a second outer surface of the housing that extends to form an extension for supporting the protruding lead, wherein the extension comprises a third outer surface, two substantially parallel surfaces in different planes and a transitional section located between the substantially parallel surfaces.
8. The device of claim 7 wherein the lead is positioned at an angle with respect to both the first outer surface and the extension.
9. The device of claim 7 wherein at least a part of the extension is positioned between the protruding lead and the shell.
10. The device of claim 7 wherein only the extension contacts the shell, forming a gap between the third outer surface and the shell.
11. A method of connecting electrical components to a network, the method comprising:
partially enclosing an electrical lead with a shell, wherein the shell is shaped to hold a cable connector in contact with the electrical lead, and
adjusting a bail between an operational position wherein the bail does not occupy the cavity and a release position wherein the bail occupies a part of the cavity.
12. The method of claim 11 wherein the shell is made of metal.
13. The method of claim 11 wherein the electrical components are located on a printed circuit board.
14. The method of claim 11 wherein the partial enclosure comprises combining a first partial shell and the second partial shell to surround a plastic surface from which the electrical lead protrudes.
15. The method of claim 14 wherein the plastic surface and the shell form a cavity into which a cable connector is inserted.
16. The method of claim 14 wherein the plastic surface is part of a plastic housing that houses a portion of the electrical lead, further comprising leaving a gap between a portion of the plastic housing and the shell to accommodate a bail.
17. The method of claim 11 further comprising positioning an electrically nonconductive layer between the electrical lead and the shell.
18. The method of claim 17 further comprising positioning the electrical lead at an angle with respect to both the plastic surface and the electrically nonconductive layer.
19. A transceiver module comprising:
a lead electrically coupled to a printed circuit board;
a metal shell designed to hold a cable connector in contact with the lead; and
a bail that facilitates handling of the transceiver module, wherein the bail is adjustable between an operational position wherein the bail does not occupy the cavity and a release position wherein the bail occupies a part of the cavity.
20. A transceiver module comprising:
a support housing;
an electrical lead protruding from a first outer surface and a second outer surface of the support housing;
an extension plane extending from the support housing to contact the electrical lead protruding from the first outer surface;
electrical components connected to the electrical lead protruding from the second outer surface;
a bail that facilitates handling of the transceiver module, wherein the bail is adjustable between an operational position wherein the bail does not occupy the cavity and a release position wherein the bail occupies a part of the cavity; and
a shell enclosing the support housing and the electrical lead and forming a cavity.
