Circular Connectors - Accessories

Circular Connectors are versatile and highly customizable for most applications. In order to use Circular Connectors in a particular application, accessories such as pins, sockets, and contact retention are required. Among the line of accessories designed for use with Circular Connectors is the 252-8555-000, a pin and socket contact retention designed for use with keyed DIN size and other types of connectors. In this article, we look at the field of application and working principle of the 252-8555-000 pin and socket contact retention.

Field of Application

The 252-8555-000 pin and socket contact retention is designed to be used with 7 and 8 mm DIN connectors and other types of connectors. The three-part contact retention system consists of two polarization plates and one contact retainer, which create two receptacles for the male and female contacts. The integration of the polarization plates produces a wide range of adjustments that allow users to customize the retention for their application. The connection is done by inserting the contact into the retainer followed by several turns of the female thread on top. These connections can then be used to assemble these contacts with products such as connectors, wires, and plugs.

Working Principle

The working principle of the 252-8555-000 pin and socket contact retention is based on its design, which enables a secure connection of the contacts with a single-turn latching mechanism. The contact is inserted into the circular base of the retainer, and is then locked into the retainer through a hand thread. The alignment of the contact end and the threads ensure that the contact is secure in the retainer and will not come loose during operation. The completion of the connection is ensured by the polarization plates, which are matingly aligned and held in place with insulating components.

The polarized plates are secured with a spring-loaded bar which helps to increase the integrity of the connection between the male and female contacts. The integrated locking system helps to ensure that the contact does not become loose during operation. The contacts are also protected against corrosion, dust, and moisture, as they are secured in place and protected in the contact retainer by means of p-shaped sealing elements. This makes the 252-8555-000 pin and socket contact retention suitable for indoor or outdoor use, including in environments exposed to harsh weather conditions.

In conclusion, the 252-8555-000 pin and socket contact retention is designed for use with 7 and 8 mm DIN connectors, as well as other types of 7 and 8 mm connectors. The built-in polarization plates, locking system, and insulation components ensure a reliable connection between the male and female contacts. This makes the contact retention suitable for indoor or outdoor applications, including those exposed to harsh weather conditions.
