OEM/ODM China Aluminum Shear Bolt Connector - Mechanical lug Shear Bolt Lug – Waxun Detail:

Overview

Torque terminals are specially designed to handle the connection between wires and equipment.
The unique shear bolt mechanism provides a consistent and reliable stopping point. Compared with traditional crimping hooks, it is super fast and super efficient, and ensures a consistent predetermined shear moment and compression force.
The torsion terminal is made of tin-plated aluminum alloy and has an inner groove-shaped wall surface.
The notable feature is that it can save labor and enhance the electrical and mechanical performance.

Overview

The terminal body is made of a high-tensile tin-plated aluminum alloy. The terminal is suitable for outdoor and indoor applications, and can provide different size specifications.

Contact torque bolt
Made of special aluminum alloy, these contact bolts are hexagonal head double-shear head bolts. These bolts are treated with high-quality lubricant and equipped with a special contact ring. Once the bolt head is sheared off, these contact bolts cannot be removed.
Plug-in
Special plug-in, put in or take out to adjust the range of applicable conductor. These inserts all have longitudinal stripes and a positioning slot.

Features and advantages of mechanical lugs and connectors	Function
Wide application range and strong versatility	For example, three specifications can cover 25mm2 to 400mm2 conductors.
The body is made of high-tensile tinned aluminum alloy	And it can be used with almost every type of conductor and material.
The bolts are made of special aluminum alloy	Good contact characteristics, can realize the connection between the copper conductor and the aluminum conductor.
Compact design	Only need a small installation space, especially suitable for large-scale applications.
Tubular spiral design inside the body to improve contact performance	Excellent electrical performance.
Centering hole and insert	The conductor oxide layer is split.
Constant torque shear head nut	The plug-in piece adjusts one size of the connection or terminal suitable for more types of wires.
Lubricated nut	The inserts help the conductor to be better centered and will not deform the conductor when the bolt is tightened.
Special features of mechanical terminals
Long handle	With extra long length, it can be used as a moisture barrier
Horizontal sealing is suitable	Suitable for indoor and outdoor applications

installation

▪ No special tools are required for installation, only a socket wrench is needed for installation;
▪ Each type uses the same reduced length, including the provision of inserts;
▪ Hierarchical fixed torque scissor head nut design to ensure reliable and firm contact;
▪ Each connector or cable lug has a separate installation instruction;
▪ We recommend using a support tool (see attachment) to prevent the conductor from bending.

The installation tools you required：
▪ Hexagon socket in correct size of A/F
▪ Ratchet wrench or electric impact wrench
▪ Highly recommended use the fixture for supporting the cutting bolt in case of conductor bending

Installation Guide

1. Choose the correct size of the terminal according to the product selection guide. Check and verified it has the same wire size as which marked in the cable and the terminal.
unscrew the shearing force bolt till it has rooms for cable to insert

2. The conductor shear end uniformity. the peel length of the conductor which should be cut referring to the recommending guide.

avoid to cut the conductor.

3.Inserting the conductor at the bottom of the torque terminal carefully.

4.Tighten the shear bolt, fixed the conductor to the terminal. the tighten the bolt from 1-2-3

5. To tighten up the bolt by the ratchet wrench or electric impact wrench, put on the strength in order from 1-2-3, first alarming phase, to apply the torque 15N.m in order from 1-2-3.
to apply the torque 15N.m in order from 1-2-3 at second time, to apply the torque till the bolt head be cutted in order from 1-2-3 at third time.
Repeat the cutting process till all the bolts down, and must be cutted from 1-2-3. Make sure to fix the terminal in the cutting process.
Make sure has the enough torque, the battery is in high gear. check the cutting results and remove the lubricant oil remained.
