15 pin d sub connector housing

Introduction to the d-sub backshell 15 pin.

Within the vast field of electronic connectors, D Sub connectors have long been a classic interface standard in industrial control, computer communication, and instrumentation due to their distinctive D-shaped metal shielding and exceptional reliability. Among the various accessories for D-Sub connectors, the 15-pin (15 Pin) plastic housing serves as a crucial component for structural protection and cable management.

Basic structure and specifications:

The 15 pin d sub connector backshell, commonly referred to as the “back shell” or “bottom shell” of the d connector, is a specialized accessory designed specifically for standard DB15 or high-density DA15 connectors. Its most notable feature is its use of high-strength engineering plastics, with common materials including black ABS (acrylonitrile-butadiene-styrene copolymer) or PBT (polybutylene terephthalate) reinforced with glass fibers. These materials not only meet stringent fire-retardant certifications such as UL94-V0, but also possess excellent mechanical strength, thermal resistance (operating temperatures typically ranging from –55°C to 110°C), and aging resistance.

In terms of structural design, the plastic casing typically employs a two-piece snap-fit design, which facilitates the welding and assembly of cables. Precise stress-relieving components (such as cable clamps or rope rings) are incorporated within the casing to securely hold the cables in place, effectively preventing the detachment of solder joints or poor contact due to external force. Additionally, the top of the casing features a standard outlet port, equipped with drive screws of UNC 4-40 or M3 specifications, ensuring stable connection and convenient disassembly of the connector on the panel or device.
