Through-bus card-connected ultra-large load capacity ring wiring with high reliability pdu

Abstract

The invention discloses a bus-through clamping-type ultra large-load capacity annular wiring high-reliability PDU (Power Distribution Unit). A waterproof wiring head is arranged at a wire incoming mounting end plate; the wire incoming mounting end plate and a wire mounting insulated end plate are arranged in an overlapping mode at a wire incoming end of a shell; multiple socket modules are arranged inside the shell; a mounting end plate and an insulated end plate are arranged in an overlapping mode at a closing end of the shell; a bus-PE, a bus-L, and a bus-N are respectively arranged inside the multiple socket modules for electrically connecting the above parts. The quick punching clamping-type connection is low in resistance, reliable, durable, stable and small in temperature rise, and fire risks are eliminated; a charged conductor is fixed and an electrical contact point is closed in the insulated shell during the whole process, hidden electrical dangers such as short circuit and contact oxidation are eliminated; due to annular wiring, single-point fault is eliminated, and the power-off range due to multi-point fault is reduced; no broken connection points exist in the whole bus, and connection is firm; temperature rise is over low, and fire risks do not exist; power distribution reliability is high; the appearance size is small, and the space is saved; and the SPD modules have hot-plug functions.

Description

technical field [0001] The invention belongs to the field of cabinet power sockets, in particular to a precision power distribution unit. Background technique [0002] PDU refers to the power distribution unit. It is the acronym for "Power Distribution Unit" in English. It is mainly used in cabinets and other places that require high power supply reliability. Output interface compatibility: national standard, European standard, British standard can be selected as needed Standard, American Standard and other world standard power socket modules, wires or wires with plugs and other output interfaces can be combined in any way to meet the different needs of customers in many countries; dual power input can be realized; product terminal input, product front panel can be used Input, product rear input and other input positions; optional terminal blocks, 16A national standard plugs, various industrial couplers and other input interfaces. SPD module can provide multiple circuit pro...

Problems solved by technology

[0003] However, the load current of the PDU in the prior art is small; the output port is not compatible with the socket and the wire with the plug; the connection between the internal wires is generally connected by soldering or self-tapping screws, due to the sandwich effect, electrical stress and thermal stress effects Excessive temperature rise will lead to fire risk; internal busbars and connection point conductors are exposed to safety hazards; single-point fault disconnection will lead to output power failure; busbar breakpoints and connectors are many, low reliability; load current is limited; appearance The size is large, occupying valuable effective space in the cabinet; the efficiency of manual production and assembly is low, and the quality consistency is difficult to guarantee

[0004] At the same time, in the prior art, the SPD module in the PDU circuit is fixedly installed in the casing and connected to the circuit. If the SPD module is damaged during work, the entire PDU circuit must be cut off, and the SPD module or the entire PDU must be replaced. circuit, seriously affecting the work of the power supply object
