Wire to Board Connectors

A wire to board connector joins a wire to a printed circuit board (PCB), facilitating signal transfer between circuits. These electronic connectors utilize a header and receptacle to connect to the PCB or cable harnesses. The circuit board features pins that can either be surface mounted or soldered through-hole.

Wire-to-board connectors are utilized to connect a wire or a group of discrete wires to a printed circuit board (PCB). They provide an efficient and cost-effective method for delivering power and signals to PCBs in automotive, industrial, lighting, and communication products. Commercial electronic equipment and household appliances commonly use wire-to-board connectors as well.

The specific application requirements will dictate the style of connector selected, as there are no standardized wire-to-board connector designs. Depending on the manufacturer, some connectors boast low-profile mating suitable for tight spaces and various locking mechanisms such as friction locks, full locks, or quick disconnects. Others may utilize a locking bar or snap-fit connection to ensure that the wire remains securely in place. While many connectors are surface-mounted to the board, others feature pins that pass through the board and are soldered on the opposite side.

Wire-to-board connectors are characterized by several specifications such as housing size, materials, the number of contacts, stacking height (the height of the connector measured from the circuit board), contact lengths, and rows of contacts. Additionally, they are defined in terms of pin pitch, which measures the distance between the centers of two conductors. Wire termination methods also vary based on wire size and number of contacts. For instance, connectors that handle significant power often feature crimped-on contacts secured with tools, while mass termination connectors accommodating 20 wires or more can be engineered for automated soldering systems.

Another recent development includes a new generation of ultra-compact connectors with profiles under 1.5 mm, designed to be compatible with automated surface mount assembly in high-volume manufacturing scenarios. To guarantee reliability, these tiny connectors typically include gold-plated contacts and strain relief features. With numerous sizes and styles available among today’s wire-to-board connectors, design engineers have more options than ever to choose the ideal power and signal delivery systems for their end products.
