Abstract

A microelectronic connector having indicating devices which are located external to the connector body. In one embodiment, one or more channels are formed in the exterior of the connector body which receive the devices and their leads. The channels are formed generally on the connector surface proximate to the circuit board to which the connector leads are being mated, thereby minimizing the length of the leads. The channels are designed to retain the leads of the indicating devices in a substantially fixed relationship to the connector body, thereby obviating the need for a cavity or recess for the indicating device, or apertures leading from the cavity/recess to the exterior of the package. A noise shield may further be installed on the connector body which helps retain the aforementioned indicating devices within external channels formed in the connector body. In one embodiment, a one-piece metallic shield is folded around the exterior of the connector body and indicating devices, thereby retaining the LEDs in place. In a second embodiment, the shield is contoured to the channel of the connector body such that the indicating devices are external to the shield and connector, thereby shielding the connector conductors and magnetics from EMI generated by the indicating devices as well as that from external sources. A method of fabricating the connector of the present invention is also disclosed.

Claims

1. A microelectronic connector, comprising:

a connector body having a plurality of walls, said walls defining a cavity, at least one recessed channel, and a board-mounting face, wherein said cavity is configured to receive a modular plug within said cavity, wherein the recessed channel has at least one land formed therein, wherein the land forms a groove bounded by an inner edge of the land and a portion of the connector body, and wherein the land has a recess in all outer edge thereof;

at least one indicating device comprising an LED, a first electrical lead and a second electrical lead, wherein said first and second electrical leads are configured to extend at least to the board-mounting face of the connector body, wherein the first electrical lead is frictionally received into the groove, and wherein the second electrical lead is received into the recess; and

an electromagnetic noise shield including at least one attaching tab, said noise shield affixed around the connector body exposing the cavity and the board-mounting face, wherein the at least one attaching tab of said noise shield folds over an edge of one of the plurality of walls to secure said noise shield around the connector body and wherein a portion of the noise shield is directly adjacent the second electrical lead and retains the second electrical Lead in the recess.

2. The microelectronic connector of claim 1, wherein the at least one indicating device is secured to said connector body by an adhesive.

3. The microelectronic connector of claim 1, wherein the plurality of walls comprises a front wall, a back wall, a bottom wall, a top wall and a first side wall and a second side wall.

4. The microelectronic connector of claim 3, wherein the at least one recessed channel is formed at a bottom corner of the connector body at a junction of the front wall, the bottom wall and the first side wall.

5. The microelectronic connector of claim 4, wherein the at least one recessed channel is formed in the connector body such that the first side wall terminates at the recessed channel and does not define a side of the recessed channel, such that the outer edge of the land formed in the recessed channel is directly adjacent the noise shield.

6. A method of manufacturing a microelectronic connector, comprising:

forming a connector body, such that said body has a plurality of walls defining a cavity configured to receive a modular plug, wherein at least one of said plurality of walls has at least one recessed channel in a portion thereof, wherein said at least one channel has a land formed therein, wherein the land forms a groove bounded by an inner edge of the land and a portion of the connector body, and wherein a recess is formed in an outer edge of the land;

installing at least one indicating device in the connector such that a first lead portion of the indicating device is received by frictional fit into the at least one groove, and a second lead portion of the indicating device is received into the recess; and

installing a shield on said connector body, said shield configured to substantially conform to at least a portion of said connector body, wherein the shield is directly adjacent the second electrical lead and is configured to retain the second electrical lead in the recess.

7. The method of manufacturing a microelectronic connector as recited in claim 6, wherein said connector body is formed by molding.

8. The method of manufacturing a microelectronic connector as recited in claim 6, wherein said shield is an electromagnetic noise shield.

9. The method of manufacturing a microelectronic connector as recited in claim 6, wherein said at least one indicating device is installed on said connector body with an adhesive.

10. A microelectronic connector comprising:

a connector body having a plurality of walls, said plurality of walls comprising a front wall, a back wall, a bottom wall, a top wall and a first side wall and a second side wall, said plurality of walls defining a cavity, a board-mounting face, and at least one recessed channel formed at a junction of the front wall, the bottom wall and the first side wall such that the first side wall terminates at the recessed channel and does not define a side of the recessed channel, wherein said cavity is configured to receive a modular plug within said cavity, and wherein the recessed channel has at least one land formed therein, such that the land forms a groove bounded by an inner edge of the land and a portion of the connector body, and wherein the land has a recess in an outer edge thereof;

at least one indicating device comprising first and second electrical leads for providing an electrical signal to said indicating device, said at least two electrical leads extending at least to the board-mounting face of the connector body, wherein the first electrical lead is frictionally received into the groove, and wherein the second electrical lead is received into the recess; and

an electromagnetic noise shield including at least one attaching tab, said noise shield affixed about the connector body exposing the cavity and the board-mounting face, wherein the at least one attaching tab of said noise shield folds over an edge of one of the plurality of walls to secure said noise shield around the connector body and wherein a portion of the noise shield is directly adjacent the second electrical lead.

11. The microelectronic connector of claim 10, wherein the indicating device is a light-emitting diode.

12. The microelectronic connector of claim 10, wherein the indicating device is a liquid crystal display.

13. The microelectronic connector of claim 10, wherein the at least one indicating device is secured to said connector body by an adhesive.
