<h1> Card Edge Connector Accessories </h1> <p> Card edge connector accessory products are ancillary to or supportive of a variety of card edge connector products. Characterized by their use of a copper contact pattern etched into the periphery of a printed circuit board as one-half of a mating connector pair, accessory products for such connectors include items such as card guides, keying plugs, retention clips, and other products of which many address needs for mechanical fixation of devices incorporating such connectors. </p> <p>
<h1> Card Edge Connector Adapters </h1> <p> Card Edge Adapter Connectors are designed to mate a card edge board directly to another one, or to a cable with a socket connector. The adapter types are card slot to card slot, or card slot to male pin header.  The mounting types are free-hanging or panel mount, with the number of contact positions ranging from 8 (4 dual) to 120. </p> <p>
<h1> Card Edge Connector Contacts </h1> <p> Card edge connector contacts are components of an interconnect system that facilitates connection of multiple discrete wires to a printed circuit board, using a copper pattern etched on the PCB as one-half of a mating connector pair. To form the other half, contacts such as these are applied to the discrete wires to be connected, and inserted into an appropriate housing. </p> <p>
<h1> Card Edge Connector Housings </h1> <p> Card Edge Connector Housings are contactless connectors designed to be used with card edge circuit boards. The housings have positions ranging from 2 to 350, accommodate card thicknesses from 0.047” to 0.093”, and have pitch dimensions from 0.024” (0.60 mm) to 0.312” (7.92 mm). They come in both free-hanging and panel mount versions. </p> <p>
<h1> Edgeboard Connectors </h1> <p> Card edge or edgeboard connectors are a style of connector system in which (typically) a pattern of exposed copper regions at the periphery of a printed circuit board constitutes one-half of a mating connector pair. A common use case being the connection of accessory cards such as graphics accelerators to computer motherboards in desktop PC applications, they offer a relatively low-cost, high density interconnect option for applications where durability is not a primary concern. </p> <p>

Card Edge Connectors

 

Card Edge Connectors are a type of electronic components specifically used for edge connection of printed circuit boards (PCBs), which achieve electrical connection through metal contacts and gold fingers on the edge of the PCB. With its modular design and high reliability, Card Edge Connectors are widely used in computer, communication, medical, and industrial equipment fields, and are key components in PCB interconnection scenarios.

 

1. What are Card Edge Connectors?

1) ‌Composition ‌

It consists of an insulating base and a metal insert. The insert is usually made of narrow and long metal strips and plated to improve conductivity and corrosion resistance.

 

The edge of the PCB needs to be specially designed to fit the insert, and the insert maintains stable contact with the socket through elastic force.

 

2) ‌Working Principle ‌

‌Insertion Alignment: The conductive traces on the edge of the PCB are precisely aligned with the connector contacts.

‌Contact Retention: The metal contacts form a reliable electrical connection and fix the PCB by a lock or clip.

‌Signal Transmission: It supports electrical signal and power transmission and is suitable for high-speed data transmission scenarios (such as 64 Gbps PAM4).

 

2. What are the Main Types of Card Edge Connectors?

1) ‌Classification by Function‌

‌PCI Card Edge Connector‌: used to connect computer expansion cards (such as graphics cards and network cards) to the motherboard.

‌High-power Connector‌: supports a current range of 5.2A to 46A, suitable for redundant power modules and industrial equipment (such as TE Connectivity products).

‌High-speed Connector‌: 0.60 mm pitch design to meet the high-speed signal requirements of data centers and communication equipment.

 

2) ‌Classification by Application Scenario‌

‌Consumer Electronics‌: SIM card connector, mobile phone battery interface.

‌Industrial and Medical‌: supports stable connection in high vibration and harsh environments (such as medical instruments and remote radio units).

‌Embedded System‌: interconnection of internal circuit boards of industrial automation and control equipment.

 

3. What are the Key Parameters of Card Edge Connectors?

‌Electrical Performance‌: current capacity (such as 3400W rated power), contact resistance (0.7-10 milliohms).

‌Mechanical Design‌: plug spacing (0.5-2.00 mm), arrangement (vertical/right angle/edge installation).

‌Environmental Adaptability‌: Corrosion-resistant coating and locking mechanism ensure contact reliability after multiple plugging and unplugging.

 

4. Industry Standards and Certifications of Card Edge Connectors

Some models are UL and TUV certified and comply with CRPS (common redundant power supply) interface specifications.

 

Standard products cover 10 to 300 contact configurations and support different PCB layer and thickness requirements.
