AI Technical Summary
The existing outdoor cable power extraction devices have problems such as small contact area, thin tips that are easy to break, tooth punctures are very destructive to the cable insulation layer, difficult to install and operate, poor specialization, thermal expansion and contraction caused by wind and sun exposure, poor contact, poor waterproof and dustproof effects, and long-term oxidation of the contact surface leads to poor contact.
Self-tapping and self-locking screws are used as the power-tapping and self-locking screws, and through the insulating layer and contact with the cable, ensuring that the power-tapping and self-locking screws are interwoven together, forming a spiral fusion contact, reducing the impact of thermal expansion, cold and vibration on the contact surface, and improving the waterproof and vibration resistance of the device through designs such as waterproof rubber rings and shrapnels.
Effectively reduce and eliminate stress caused by cable vibration, avoid poor contact caused by thermal expansion and contraction, improve the installation convenience and service life of the device, and enhance the waterproof and dustproof effects to prevent oxidation of the contact surface.
