Electronic device having connector with integrated shielding

Abstract

An electronic device may have a housing in which electrical components on a printed circuit board are mounted. A connector may be mounted to the edge of the printed circuit board using solder. The connector may have a threaded portion that protrudes through the housing. A threadless portion of the connector may be aligned with the housing. The connector may have a metal body member covered with a metal shell. The metal shell may have a portion that covers the electrical components and serves as an electromagnetic interference shield for the electrical components. The connector may have a threaded barrel. The threaded barrel may have a threaded outer portion with a diameter that is larger than a threaded inner portion. The threadless portion of the connector may lie between the threaded outer and inner portions.

What is claimed is: 
     
       1. A connector, comprising:
 a threaded barrel having a first threaded portion with a first diameter that is configured to mate with a coaxial cable connector and a second threaded portion with a second diameter that is smaller than the first diameter; 
 a metal body member having sidewalls that extend around a threaded opening that receives the second threaded portion of the threaded barrel; and 
 a metal shell in which the metal body member is mounted, wherein the metal shell comprises sidewalls that completely surround the sidewalls of the metal body member and that form a first portion of the metal shell, and wherein the metal shell comprises a second portion that extends outwardly from the first portion to form an electromagnetic shielding cavity that is configured to cover electrical components mounted therein. 
 
     
     
       2. The connector defined in  claim 1  wherein the metal shell and the body member have aligned openings. 
     
     
       3. A connector, comprising:
 a threaded barrel having a first threaded portion with a first diameter that is configured to mate with a coaxial cable connector and a second threaded portion with a second diameter that is smaller than the first diameter; 
 body structures having a threaded opening that receives the second threaded portion of the threaded barrel, wherein the body structures include a metal shell that is configured to form an electromagnetic interference shielding cavity and a body member mounted in the metal shell, and wherein the metal shell and the body member have aligned openings; and 
 a set screw in the aligned openings. 
 
     
     
       4. The connector defined in  claim 3  wherein the second threaded portion has a flat area and wherein the set screw bears against the flat area. 
     
     
       5. The connector defined in  claim 4  wherein the first threaded portion has threads with a thread initiation point and a thread termination point and wherein the thread initiation point and the thread termination point are located out of view on a lower portion of the first threaded portion when the set screw bears against the flat area. 
     
     
       6. Apparatus, comprising:
 a printed circuit board; 
 electrical components mounted on the printed circuit board; and 
 a connector having comprising: 
 a metal shell that forms an electromagnetic interference shielding cavity covering at least some of the electrical components, the metal shell having an opening; 
 a conductive pin mounted within the metal shell, the conductive pin extending into the opening and having a first end and a second end opposite the first end that is electrically coupled to the electrical components by a conductive path on the printed circuit board; and 
 a removable connector component in the opening of the shell that is detachably coupled to the first end of the conductive pin, wherein the removable connector component transmits signals to the electrical components through the conductive pin, and wherein the removable connector component is configured to connect with a mating connector. 
 
     
     
       7. The apparatus defined in  claim 6  wherein the electrical components include at least one integrated circuit. 
     
     
       8. The apparatus defined in  claim 7  wherein the removable connector component comprises a threaded barrel configured to mate with a coaxial cable connector and wherein the integrated circuit comprises an amplifier. 
     
     
       9. The apparatus defined in  claim 6  further comprising:
 a metal body in the opening of the metal shell, wherein the removable connector component comprises a threaded metal barrel that is configured to mate with a coaxial cable connector. 
 
     
     
       10. The apparatus defined in  claim 9  wherein the threaded metal barrel has a first threaded portion with a first diameter and a second threaded portion with a second diameter that is smaller than the first diameter. 
     
     
       11. The apparatus defined in  claim 10  wherein the metal body has a threaded opening that receives the second threaded portion. 
     
     
       12. An electronic device, comprising:
 a printed circuit; 
 electrical components on the printed circuit; 
 a housing with an opening; and 
 a connector that is mounted on the printed circuit, wherein the connector comprises:
 a connector body having a threaded opening; 
 a pin mounted in the connector body, wherein the pin has an end that extends into the threaded opening; and 
 a threaded barrel with a first threaded portion, a second threaded portion, and a threadless portion between the first and second threaded portions, wherein the connector protrudes through the opening in the housing so that the threadless portion is aligned with the housing, wherein the threaded opening in the connector body receives the second threaded portion of the threaded barrel, and wherein the end of the pin is received in an opening in the threaded barrel when the second threaded portion is received in the threaded opening. 
 
 
     
     
       13. The electronic device defined in  claim 12  wherein the first threaded portion has a diameter that is larger than the second threaded portion. 
     
     
       14. The electronic device defined in  claim 13  wherein the connector has a metal shell that forms an electromagnetic interference shielding cavity covering the electrical components. 
     
     
       15. The electronic device defined in  claim 14  wherein the electrical components include an amplifier.
