Rectangular Connectors - Accessories

1. Overview

Rectangular connectors - accessories refer to supplementary components designed to enhance the performance, durability, and functionality of rectangular electrical connectors. These accessories include covers, locking mechanisms, cable clamps, adapters, and sealing elements. They play a critical role in protecting connectors from environmental factors, ensuring mechanical stability, and enabling compatibility across systems. With the increasing complexity of electronic systems in industries like telecommunications, automotive, and industrial automation, these accessories have become essential for maintaining reliable signal and power transmission.

2. Main Types and Functional Classification

TypeFunctionApplication Example
Dust CoversProtect connectors from dust, moisture, and debrisOutdoor communication equipment
Locking RingsPrevent accidental disconnection under vibrationAerospace sensor systems
Cable ClampsSecure cables to prevent strain on contactsIndustrial machinery
Adapter PanelsEnable interface between different connector standardsData center server racks
Sealing GrommetsProvide IP67-rated watertight sealsMarine electronics
Mounting BracketsFacilitate secure panel or PCB installationMedical diagnostic devices

3. Structure and Composition

Typical accessories consist of:

  • Material: High-temperature resistant plastics (e.g., PBT, nylon) or metal alloys (e.g., aluminum, stainless steel)
  • Design: Molded housings with snap-fit or threaded interfaces
  • Coatings: Corrosion-resistant platings (e.g., nickel, zinc)
  • Sealing Elements: Elastomer O-rings or gaskets for environmental protection

4. Key Technical Specifications
