Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) types are versatile electrical connectors used to attach two PCBs together mechanically and electrically. 4-1658012-1 is one of the most commonly used connectors of this type. It is widely used in applications such as automotive, industrial, consumer, and telecom.

The 4-1658012-1 consists of a plastic housing inside which there are 2 rows of 2.5 mm pitch, edge type female contacts. It is suitable for a range of board thickness from 0.45mm to 2.1mm. Each of the female connections has an electrical current and voltage rating of 0.5 A at 30V. The connectors can also withstand up to 5 mating cycles and up to 8 logic operations.

The basic anatomy of 4-1658012-1 is a two-piece array of edge type female contacts which are crimp-mounted onto a PCB and is pressing against a pair of pins in a port. When inserting a mating male port, there is first an electrical connection which is made via the contact points and then a mechanical connection through the spring mechanism.

The working principle of the 4-1658012-1 is simple and straightforward. A spring mechanism inside the contacts when pressed by the mating male port, creates an electrical connection while providing a stable, long-lasting mechanical connection. The spring also ensures that the forces applied to the female contact pins are balanced for maximum reliability in vibration and shock resistance, while avoiding any force build up due to the pressure from the mating male port.

Aside from the superior electrical and mechanical properties of the 4-1658012-1, the design also enables the two PCBs to be mated easily and quickly without the need for extra tools or expensive programming stages. Furthermore, the design also incorporates a dust shield which provides protection against dust and dirt ingress, while still allowing full signal transmission.

In summary, 4-1658012-1 is one of the most popular rectangular connectors - arrays, edge type, mezzanine (board to board) types due to its versatile electrical and mechanical properties, its ease of use, and durability. The simple spring mechanism guarantees reliable electrical and mechanical connections, while the dust shield protects the pins from contamination, and the dimensions comply with most board requirements.
