Description

universal adapter

【Technical field】

The utility model relates to a power installation engineering device, in particular to a universal connecting device.

【Background technique】

At present, the connection between the main line of the power distribution network and the branch line before entering the house is mainly to connect the two by hand-tying, piercing wire clips and the like.

Most of the wires and wires are connected by hand-tied wires. During long-term use, we found that the hand-tied wires have safety hazards such as poor contact and easy fall off, which require frequent replacement and maintenance. Bring very big trouble to the work of our electric power department, expend manpower and material resources.

The way of piercing the clip is also often used, but after use, we also found that the damage of the piercing clip to the wire conductor is very serious. And because the outer diameters of the wires produced by various manufacturers are different, the standards of the wires are also diversified due to the diversification of requirements, and the outer diameters of the wires are also in a variety of forms. The overload capacity decreases and the mechanical performance of the conductor decreases, and the wire with a small outer diameter will have poor puncture and clamping, resulting in insufficient overload capacity due to insufficient contact. In addition, there are also differences in the materials and specifications of copper wires and aluminum wires, and the standards for adapting the wires to the puncture clamps are also different and insufficient.

The application of C-type wire clips in line branching is also very common, but there are many types of C-type wire clips, and different types of wires correspond to different types of wire clips. In actual use, it is often impossible to fit the wrong wire clip by mistake. Poor contact or crimping is not reliable.

For the above situation, we provide a solution.
