FFC and FPC (Flat Flexible) connectors are some of the most widely used connectors in the electronics industry. They provide the most important connection between components and circuits, making them an essential part of a power system or other electronic applications. The 88190-6 is a typical example of an FFC or FPC connector. It is a 40-position 4-row mini-connector with an operating voltage rating of 1A.

The 88190-6, like all FFC and FPC connectors, has two parts: the housing and the receptacle. The housing is the part that attaches to the board. It contains a series of contact pins (also called terminals or leads) which protrude from the plastic to make contact with the circuit board. The receptacle is the part that attaches to the cable, and contains a series of spring-loaded contact points which contact the contact pins of the housing.

The housing and the receptacle are connected with a flat flexible ribbon cable or ‘FFC’. The width of the cable is typically 1mm or 1.27mm, and is very flexible, allowing it to be bent and twisted into tight corners. The length is usually 5-6mm for standard 40-position connectors, but can be customised if necessary.

The main application for the 88190-6 is the efficient connection and routing of signal pathways between circuit boards. The advantages of such connectors include flexibility in design, improved signal integrity, and very low insertion forces. They can be used in a variety of applications, including robotic control, medical equipment, audio/visual equipment, portable devices, and more.

In terms of working principle, FFC and FPC connectors provide a quick and easy way to connect two or more circuits. To ensure a reliable connection, the contact pins need to be firmly and evenly spring-loaded. This is achieved by first ensuring that the contact pins of the housing are properly aligned with the contact pads of the circuit board. Then the receptacle can be inserted into the housing and the contact pins are pressed firmly and evenly against the contact pads of the board.

The contact pins can then be moved freely in the direction of insertion, forming a secure connection. The 88190-6 is an efficient connector due to its low insertion force and its low profile design. It also has a very high retention force and is designed to withstand high temperatures, ensuring a smooth operation even in harsh conditions.

To summarise, the 88190-6 connector is a FFC or FPC connector designed for routing signal pathways between circuit boards. It has a 40-pin, 4-row design with a low insertion force and low profile, making it ideal for a wide range of applications. Its main advantage over traditional connectors is its flexibility and its ability to effectively transfer signals without any interference.
