## **Introduction** 

The High Current Edge family of connectors provides high reliability and economy in packages compatible with industry standards.  While many new card edge connectors for signal applications have moved toward higher density configurations (0.050" and 1 mm centerlines), Tyco Electronics has redesigned the 0.100" standard edge product family to carry more current, for low power distribution. 

This product family includes the following: 

- CROWN EDGE Products 

- Standard Edge Connector — 2nd generation 

The connectors serve low durability cycle applications which do not have the available room for a traditional 2-piece power distribution connector.  In other applications, a lowprofile connector is needed to allow for better airflow / less airflow restriction. 

This grouping of power card edge connectors is focused on providing high current density with the favored multi-point contact design which reduces contact interface resistance. 

The connectors were used originally in the ISA Standard for computer expansion cards.  Today these connectors are being used in applications such 

as; DC-to-DC converters, low-wattage power supplies, industrial grade card extenders and general low cost I/O applications requiring durable/rugged card edge contacts.  The improvements made still allows use in the original applications and they provide a lower resistance connection due to the high conductivity contacts plated with a minimum 30 micro inches gold. 

The options include vertical or right-angle PCB mounting as well as straddle-mount configurations for co-planar PCB applications.

Power Connectors & Interconnection Systems 

## **CROWN EDGE Card Edge-style High Current Connectors** 

## **Product Facts** 

- **Low cost power solution** 

- **Power, signal and mixed modules** 

- **35A per power contact** 

- **Mates with .062 (1.6 mm) thick card edge or bus bar tab** 

- **Press-fit or solder tail terminations** 

- **True hot-plug power modules** 

- **Meets regulatory safety requirements** 

- **All CROWN EDGE products in this section are RoHS compliant.** 

## **Typical Applications** 

- **Board-to-board power connections** 

- **DC-DC converters** 

- **Uninterruptible Power Supply (UPS)** 

- **Power supplies** 

CROWN EDGE connectors are a board-to-board power interconnect solution that uses ELCON high performance CROWN BAND contact technology configured to mate directly with a printed circuit board edge or — for higher currents — with a solid bus bar. Power and signal can be combined and mounted end-to-end to meet the requirements of the applications. 

## **Product Highlights** 

## **High-current Card Edge Interface** 

CROWN EDGE connectors use Tyco Electronics proven ELCON CROWN BAND contacts that provide multiple points of contact for high current, and low voltage drop and minimal heat generation. The desired current rating for most applications can be achieved by bussing multiple contacts or even modules. For even higher currents, CROWN EDGE connectors can be mounted onto a bus bar, and mate directly with a bus bar tab. Optimum interface to the mounting PC board is achieved through five termination tails. 

## **Flexible Modular Design** 

To make easy work of power distribution design, CROWN EDGE connectors are available in modules of 2 and 3 contact segments with power or signal contacts or a combination of both in a single module. Modules can be placed end-to-end for assemblies up to 8" (203.20 mm) long. Custom molded configurations are possible on highvolume projects. Consult Tyco Electronics or your local Tyco Electronics sales representative for details. 

## **Versatile Power Arrangements** 

Opposing contacts are isolated, so power connections at different voltage levels can be on one side of the board, with ground or power return on the other side. 

## **True Hot-Plug Support** 

CROWN EDGE power modules that support current interruption under load as defined by safety regulatory agencies are also available for mating to a metal blade or bus bar tab. These true hot-plug modules allow current interruption under load by incorporating a contact design that restricts the effects of arcing to areas that do not compromise the integrity of the connection.

## **Current Ratings** 

The chart below demonstrates the performance of the CROWN EDGE power contact by showing the temperature rise at different current levels applied to two power contacts connected in series. 

## **Safety Regulatory Compliance** 

CROWN EDGE connectors have been evaluated by Underwriters Laboratories and have been found to comply with the requirements of U.S. standard UL1997 and Canadian standard C22.2 No. 182.3-M1987. 

Current rating for any given application will depend, among other things, on the module combination, PCB copper trace volume, and internal equipment temperature/air flow. Mounting and mating to a bus bar will increase current ratings. 

## **Compliance with Current Interruption Requirements** 

Hot-plug CROWN EDGE modules are available for applications that require current interruption as defined by safety regulatory agencies. These power-only modules have been evaluated and recognized by Underwriters Laboratories for current interruption up to 50 cycles as per the UL1977 standard. See hot-plug requirements on page 180.

## **Custom Solutions** 

## **Non-standard Modules** 

In case the standard CROWN EDGE modules do not meet your design requirements, Tyco Electronics has the capability to mold any combination of power and signal contact layouts in 2 and 3 segment modules. 

## **Application-specific Custom Designs** 

Tyco Electronics has a long history of designing and building application specific custom connectors, and CROWN EDGE connectors are no exception. A one-piece CROWN EDGE insulator, instead of a combination of several modules, provides a more robust interconnection design, as well as cost savings in high volume projects. Consult Tyco Electronics Customer Service for details.

- **Combines industry standard 0.100" pitch card edge format in a high power density design** 

- **Industry-proven multi-beam power contact design** 

- **High conductivity contact materials** 

- **High temperature housing materials** 

- **UL 94V-0** 

- **Selective gold plating for high performance with low cost** 

- **.000030 [0.00076] gold in contact area. Tin/lead on posts with entire contact nickel underplated** 

- **Power Contact Current Ratings:** 

- **38 amps — Single Contact** 

- **22 amps — on each of 4 adjacent pairs (8 power contacts)** 

- **Signal Contact Ratings:** 

- **6 amps — Single Contact** 

- The trends in electronic power supplies require high current density and lower cost. In addition, smaller sized connectors are needed to provide less airflow restriction for cooling the power supplies. The SEC-II power connectors offer an ideal combination of low-current and highcurrent connections in a single, durable design. 

- SEC-II power connectors are built on an expandable tooling platform which allows for a variety of combinations of power and signal contacts, all 

combined in a single molded housing. The vertical press-fit versions are ideal for high density stacking of cards into a backplane or for low air restriction of blade-style power supply designs. The straddle mount style offers a true co-planar interconnection with a total height of less than 4 mm from the top surface of the PCB. 

SEC-II power connectors are currently in use in high-end computer and data storage equipment. Extensive testing in exposure to high vibration and 

shock has proven these connectors equally suited for industrial applications as well, where low contact resistance and high current density is required. 

- **4 amps — on each of 6 adjacent contacts**
