D-shaped connectors are a type of versatile electrical connector used in a variety of commercial and industrial settings. In particular, they are often utilized for data, audio, and video applications. D-shaped connectors are distinguished by their arrangement of contacts on either side of the connector, which form a “D” or diamond shape when viewed from the end. D-shaped connectors typically feature between 9 and 37 contacts and come in various contact configurations and contact sizes.

The 5552568-2 is a type of D-shaped connector, described as a Polarized Splined Jackscrew in an IP68-rated housing. It is a two-piece system comprised of a thermoplastic insulator and a metal shell. The thermoplastic insulator is typically made of PBT or Nylon 6/6 and features raised teeth on the interior of the female housing and a series of holding lugs which provide robust retention and guarantee proper mating. The metal shell is typically made of stainless steel and its two seals provide a means of achieving IP68 protection.

In applications, this jackscrew is often used as a secure locking device to ensure a reliable and robust electrical connection. It is typically mated to a polarizing insulator, which divides the female housing into two distinct halves. This dual-half impedes incorrect mating, as only the matching polarizing insulator enables proper mating between the two halves. The connection can be further secured by anchoring the jackscrew to either the male- or female-side of the mating connector. This action provides additional physical security and increases the pull-out strength of the assembly.

In terms of working principle, the 5552568-2 jackscrew works by threading a locking screw into the female housing. This screw has two distinct threads, allowing it to be rapidly threaded and unthreaded with the use of a screwdriver. When the screws are tightened, the internal lugs on the threaded side of the female housing are firmly engaged. This guarantees a secure mechanical connection between the two halves of the connector despite any vibrations or shocks.

The 5552568-2 jackscrew is a versatile connector that can be utilized in a variety of applications. It is designed to provide a secure and reliable locking connection, and its IP68-rated housing ensures reliable performance in harsh and corrosive environments. This makes the jackscrew an ideal accessory for applications such as automotive, military, and aerospace applications.
