电缆接头

A cable gland is a device used to attach and secure the end of an electrical cable to equipment, providing strain relief and environmental sealing.

技术定义与适配语境
典型 电缆接头 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

A cable gland, also known as a cable connector or fitting, is a mechanical device designed to securely attach and terminate the end of an electrical cable to electrical equipment, enclosures, or junction boxes. It serves multiple critical functions: providing strain relief to prevent cable pull-out, sealing the entry point against environmental contaminants (dust, moisture, liquids), and ensuring electrical continuity and grounding in some designs. Cable glands are essential for maintaining the integrity and safety of electrical installations in industrial settings.

定义
A cable gland, also known as a cable connector or fitting, is a mechanical device designed to securely attach and terminate the end of an electrical cable to electrical equipment, enclosures, or junction boxes. It serves multiple critical functions: providing strain relief to prevent cable pull-out, sealing the entry point against environmental contaminants (dust, moisture, liquids), and ensuring electrical continuity and grounding in some designs. Cable glands are essential for maintaining the integrity and safety of electrical installations in industrial settings.
工作原理
Cable glands work by mechanically gripping the cable's outer sheath or armor through compression, typically using a threaded body, sealing ring, and compression nut. As the nut is tightened, it compresses the sealing ring against the cable and the gland body, creating a secure, sealed connection that prevents cable movement and ingress of external elements.
材料
Common materials include brass (general use)stainless steel (corrosive environments)nickel-plated brassaluminumand plastic (nylon or polyamide for non-metallic applications). Sealing elements are often made from neoprenesiliconeor EPDM rubber.
IP Rating
IP68 (common for waterproof applications)
Thread Size
M12 to M75 or NPT equivalents
Voltage Rating
Up to 1000V AC/DC
Temperature Range
-40°C to +100°C (varies by material)
Cable Diameter Range
3mm to 75mm
标准
ISO 9001IEC 62444DIN EN 50262

常见问题

What is the difference between a cable gland and a conduit connector?

A cable gland secures and seals individual cables, providing strain relief and environmental protection. A conduit connector attaches and seals conduit (tubing) to enclosures, protecting multiple wires inside but not providing direct cable strain relief.

How do I select the right cable gland?

Consider cable diameter, thread size of the entry point, environmental conditions (IP rating), material compatibility (e.g., corrosion resistance), and certifications (e.g., ATEX for hazardous areas). Always match the gland to the cable type (e.g., armored, unarmored).
