QFS-052-04.25-H-D-PT4-TR application field and working principle

QFS-052-04.25-H-D-PT4-TR is a type of rectangular connector belonging to the Arrays, Edge Type, Mezzanine (Board to Board) family. It is typically used in industrial settings, consumer electronics, and other instrumentation and audio applications. It functions by mating two components, and thereby providing multiple points of electrical continuity between them. The two components must have parallel surfaces, which may be either two planar surfaces of an IT or printed circuit board, or a planar surface of one of the components and a conformal surface of the other.

The QFS-052-04.25-H-D-PT4-TR provides a range of contacts that are typically recessed and designed with pocket features. It is specially designed to mate with a 0.025 inch space between the mating surfaces, making it ideal for use in harsh environments and providing excellent EMI/RFI shielding. Additionally, because of the increased contact area provided by the pocket feature, it can provide a more reliable connection even in the presence of shock and vibration. The recessed nature of the contacts also prevent any oxidation or corrosion of the contact area.

The contact mechanism of this type of connector is composed of a non-metallic housing with an internal strain relief construction, and a series of contacts which are crimped onto a contact support member. The contact support member holds the contact in place, and is held securely by the strain relief. The connection is made by first inserting the contacts into the housing, which holds them in the correct alignment. Then, the contact support member is inserted into the housing until it locks in place.

The contact support member is made up of two separate pieces; the main body and the contact retainers. The main body is responsible for providing the mechanical and electrical connection between the contact and the housing. It has a series of pins and a raised central point which ensure the correct alignment of the contacts. The contact retainers act as a spring to maintain tension between the contacts and the contact support member. This tension ensures that the contact remains firmly seated in the housing when the connection is made.

The contact itself is typically a metal alloy, and may be either a single-piece or a two-piece design. The contact shape can either be a straight, angled, or in-line type. In-line contacts are usually used when space is at a premium, as they take up less room due to the recessed nature of the connection. Depending on the application, the contacts may also be plated with either gold or tin for improved electrical performance.

The QFS-052-04.25-H-D-PT4-TR is a durable and reliable connection solution, which is capable of maintaining a secure and effective connection even in challenging environments. Its recessed nature and pocket design provide improved EMI/RFI shielding, as well as extra contact surface area for increased reliability. Additionally, its two-piece contact design ensures that the connection is firmly seated in the housing, and its optional gold or tin plating provides extra electrical conductivity. All of these features make it an ideal choice for a wide variety of industrial, consumer electronics and other instrumentation and audio applications.
