Description

Insulation shell for branch line

technical field

This patent relates to a power distribution unit (PDU), more specifically, to a branch line insulation casing, a power distribution unit using the casing, and a manufacturing method of the power distribution unit.

Background technique

High-tech industries such as computers, communications, and networks often require dedicated power distribution units (PowerDistribution Unit, PDU) for efficient and stable power supply. But existing power distribution units often have significant deficiencies. For example, when the core of the input power cord is a multi-strand wire twisted together, the metal blade can easily cut off the multiple sub-wires in the periphery, resulting in a decrease in conductivity; when the input power cord only contains a single-strand wire core, the metal blade Cutting the wire core will reduce the cross-sectional area of the wire core and affect the electrical conductivity. Or the increase of conductive connection points increases the probability of failure, and any loose connection point (for example, loose connection caused by vibration) will cause the conductive connection to be disconnected, resulting in connection failure. At the same time, the whole structure has many parts and is inconvenient to assemble. Therefore, a power socket is needed to solve the above-mentioned defects in the prior art.

In order to solve the above technical problems, those skilled in the art have invented a wire clip and a power socket using the wire clip. For example, in the patent application number 200920130261.X, the wire clip is a single part, which can only be used for a single wire diameter, and it cannot be applied if it is too large (unable to fasten) or too small (easy to fall out); Injection-molded plastic parts around the interface. This solution requires the use of an injection molding machine, which is complicated to operate and low in efficiency. Or for example, in patent application number 201320686975.5, the terminal block is a closed ring, although it is suitable for various wire diameters, it needs to be penetrated from one end of the wire each time it is used, and it needs to be compressed with screws, which is less efficient.

Therefore how to invent a kind of wire clamp and power distribution unit that can adapt to multi-diameter wires and can be installed simply and conveniently is the common direction of efforts of those skilled in the art.
