Copper sheet clamping groove

Abstract

The invention provides a copper sheet clamping groove; a main body of the copper sheet clamping groove is provided with at least one primary wire bayonet, and primary cutting edges are respectively arranged on two sides of an opening of the primary wire bayonet. A secondary wire bayonet is further arranged above the primary wire bayonet, secondary cutting edges are arranged on the two sides of an opening of the secondary wire bayonet respectively, and the width of the secondary wire bayonet is smaller than that of the primary wire bayonet. The rapid stamping clamping type connection is low in resistance, reliable, durable, stable and small in temperature rise, and the fire risk is eliminated; an electrified conductor is fixed in the whole process, and electrical contact points are sealed in the insulating outer shell, so that electrical potential safety hazards such as short circuit and contact point oxidation are eliminated; the whole bus is free of broken contacts, firm in connection and clean in nodes; the problem of fire risk caused by over-high temperature rise due to sandwich effect, electric stress and thermal stress effect when tin soldering or self-tapping screw connection is adopted is avoided; and the power distribution reliability is improved.

Description

technical field [0001] The invention belongs to the field of cabinet power sockets, in particular to a copper sheet slot. 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, terminal blocks 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 end input, product front Different input positions such as panel input and product rear input; optional terminal blocks, 16A national standard plugs, various industrial couplers and other input interfaces. SPD module can provide multiple circuit protection func...

Problems solved by technology

[0003] However, the load current of the PDU in the prior art is small; the output port is single and cannot be compatible with the socket and the wire with a plug; The stress effect will cause the temperature rise to be too high and there is a risk of fire; the internal busbar and connection point conductors are exposed to pose a safety hazard; a single point fault disconnection will cause output power failure; there are many busbar breakpoints and connectors, and the reliability is low; a single product can be Fewer output ports are provided; the load current is limited; the overall 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

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
