The Conxrite® CNX V Series is a single or dual row, male pin header designed to provide a positive locking method of securing connectors to a printed circuit board. Previously, there were three categories of headers with the prices and styles varying in each. The first header introduced to the market was a simple vertical PCB-mounted pin. As equipment evolved, engineers required a more effective method of retaining the connector and header together. This prompted the introduction of the friction lock header. To accomplish this, a design change was made adding a friction tab to the side of the header base. In fact, this locking mechanism is not truly positive in nature but rather a method of adding friction pressure to the side of the header connector increasing the extraction force required.
Certain industries have required a more positive locking mechanism in conjunction with polarity registration. Component manufacturers then developed a more positive locking device together with polarity registration in order to meet these requirements. As a result, the addition of these required features escalated the price into the more expensive 20 cent per pin range. Furthermore, a new connector had to be developed to mate with this positive locking header thus driving up the position costs even higher. VCC's CNX V Series header has been developed to fill the gap between the low cost friction header and the more expensive positive locking header. To accomplish this VCC took the existing friction header and redesigned the tab to incorporate a finger release lever with a detent resulting in a polarized positive locking header. In addition to the "Click, it's locked" feature, this unique lever prevents the header connector from being inserted in a reverse position. This fills the requirement of providing polarity protection. Removal of the commonly used standard ramp connector from the locking header is accomplished simply by inserting one's fingertip between the connector and the header lever thus disengaging the lock, permitting the connector to be extracted. The locking header is available in strips of 28 positions which can easily be cut to provide any pin arrangement or can be supplied in pre-cut segment combinations. It is available in both vertical and horizontal configurations. The CNX Series header is molded from black thermoplastic material rated U.L. 94 V0. The pins are phosphor bronze with a tin-sulfamate plate. Features:
- Locking lever provides polarity integrity by restricting insertion of locking header in reverse.
- Lever clicks and locks preventing header connector from being retracted inadvertently.
- Locking header available in 2 to 28 pin positions, vertical or horizontal configuration.
- Designed for both vertical and horizontal mounting on the printed circuit board.
- Pins are .025" square brass, tin plated, located on .100" centers.
- Locking header mates with VCC locking header connectors P/N 450 30X or equal.
