Positive Lock terminals by TE Connectivity

Reliable and convenient connection

This week, we recommend to you Positive Lock terminals, including their compact versions. The showcased products are supplied by a well-known, specialist connector manufacturer TE Connectivity.

For decades, terminal connectors have been among the most popular ways of connecting wiring to electromechanical components such as relays, contactors, switches, programmers. They are also applied in power circuits and controllers, whether in domestic appliances (white goods, audio/video devices), computers, the automotive industry or even industrial machinery. Flat terminals are easy to plug in and remove, which facilitates the maintenance and servicing of equipment, especially when such work involves replacement of its parts.

In applications where terminal connections are exposed to shock and vibration, there is a risk of electrical connection disruption. In such cases, snap-on terminals are used, among which the Positive Lock series from TE Connectivity deserves a special mention. These models differ from the competing solutions at first glance. Beside their sturdy design, the locking mechanism fitted with a special depressor is their distinguishing feature. The mechanism has two purposes. First of all, it makes the connection firm and safe. When connected, the latch snaps into the opening in the male connector, establishing a secure link. The terminals do not require a great deal of force to connect, and disconnecting them is just as easy – provided that it is done when the depressor is deflected. In addition to easy mating, the locking mechanism features an audible and tactile click. Thanks to that, the installer can be sure that the electrical connection has been made correctly and will achieve the expected rated performance (in many devices, visual inspection of the connection is either difficult or downright impossible). The manufacturer has also ensured special housings for the Positive Lock terminals. Note that the housing does not affect the operation of the locking mechanism, and the depressor can be operated freely.

The largest group of Positive Lock terminals are the 6.3 mm wide, 0.8 mm thick models. Finally, we would like to point out that the range of Positive Lock terminals in the TME catalogue has recently been expanded to include smaller, 2.8 mm wide terminals, as well as compatible housings. The latter feature an extended body with a grip which facilitates connections in hard-to-reach areas.
