Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)
Rectangular connectors are a type of connector that is found commonly in use for commercial, industrial, and military purposes today. They share many common features with other types of connectors such as coaxial, D-subminiature, etc., but they have some unique characteristics as well. The 91931-21141 is a type of rectangular connector, designed for use in board-to-board applications. It has an array of contact pins, as well as several edge types, that make it highly versatile for these sorts of applications. This article will explore the uses and working principle of 91931-21141 connectors.
The 91931-21141 is a popular choice for board-to-board applications due to its small size and robust design. It is a double row, top entry connector with gold plated contacts and an insulation displacement contact (IDC) termination. This means that the contact pins do not require a separate termination step, which eliminates the need for crimping tools. This makes the 91931-21141 very easy to use and reliable in applications.
The 91931-21141 uses edge-type connectors, which are designed to fit into the edge of printed circuit boards (PCBs). This allows these connectors to be used on either side, depending on which side of the board needs to be connected. The edge type of the connector also ensures that the contact pins stay in place when the connector is mated. This makes them particularly useful in critical applications, where the entire board must stay securely connected at all times.
The 91931-21141 has three rows of 17 contact pins which enable various types of connections to be made. The three rows are arranged in a T shape, with the middle row having the most pins while the two side rows have reduced numbers of pins. This arrangement allows the pins to be connected to the edge of the board, as well as to adjacent boards in a mezzanine configuration. This expands the range of connections that can be made with these connectors.
The working principles of the 91931-21141 are based on the concept of insulation displacement contacts (IDC). This is a form of contact technology that has been used for many years, and it remains popular in the industry. It involves a mechanism that slices the insulation off of the contacted wire, and then mechanically secures the connection at the next level. This allows for quick and easy installation, as well as reliable and permanent connections.
The 91931-21141 also uses a unique keying system that ensures that the contact pins remain in place during mating. This helps to ensure that the connection will be reliable, and that there will be no accidental connections occurring during mating. The pins are also protected from physical damage, which is very important in these types of applications.
In conclusion, the 91931-21141 is a versatile edge type rectangular connector that is designed for use in board-to-board applications. It employs an array of contact pins and insulation displacement contact (IDC) technology for quick and easy connections. The 91931-21141 is also protected from physical damage, and uses a keying system to ensure a secure connection when mated. As such, it is an ideal choice for a wide range of industrial and military applications.
