Abstract
The utility model discloses a power distribution unit for street lamps, which is primarily composed of a wiring plate and a power fuse seat. The lower end of the wiring plate is fixed to corresponding pressing type pressing plates which are connected with the power fuse seat by guide wires. The utility model has the advantages of artful design, reasonable structure, and simple exposing laying operation. The contact area of the pressing plates and the guide wires is increased by four times. Thus, electrical conductivity is good, contact resistance is less, and pressure drop is reduced. The temperature rise of press plate resistance is less than or equal to the temperature rise of conductor resistance; the proper power consumption of circuits is reduced. Thus, the utility model has energy-saving and value-added functions, and effectively overcomes the defects that the operation of traditional products is complex and the contact area of the wiring plate and the guide wires is small.
Description
The utility model relates to a kind of street lamp power distribution equipment, particularly relates to the terminals of this kind power distribution equipment.
Along with the raising of social civilization degree, street lighting is in municipal administration, civilian road construction, and it is important more and more to seem.Though at present traditional street lamp wire connection plate manufacturing process is simple, makes a call to nine holes on an epoxy insulating board, installs bolt nut, fixedly mounts two power fuse seats more onboard.But the terminal block of this kind structure, in the practice of construction out of doors, the operation of installation just seem trouble, complexity.Cable conductor will be connected to terminal block, then will use JDT type binding post earlier, connects earlier with fluid pressure type Press Plier binding post and cable, pressure connection terminal could be fixed on the terminal block like this, and this technology makes the contacting section of terminal block and lead very little.And because street lamp is to work out of doors for a long time, the structure of the unlimited exposed conveying appliance of this kind, expose to the sun and rain, in the course of time, the oxidation of the power supply connecting terminal of terminal block, copper chlorine tend to cause the resistance of contact to strengthen, the electric conductivity variation, it is big that contact current becomes, and the current loss of circuit is also big, and voltage drop is serious.If ponding is stained with on the terminal block, also can cause the accident of line short, power failure, outage, make the street lamp in blocks in some zone can't work a slice dark.The structure of opening wide in addition exposed conveying appliance to operating street lamp rush to repair, maintenance work caused very big danger and sense of insecurity.
The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, and constructing operation is simple, and contacting section amasss big presser type street lamp block terminal.
The technical solution of the utility model is, a kind of presser type street lamp block terminal mainly is made up of terminal block and power fuse seat, and its characteristics are: the lower end of terminal block is fixed with the pressing plate of opposite-compacting type, and pressing plate is connected by lead with fuse holder.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, rational in infrastructure, reveal outer constructing operation and simple, also make the contact area of pressing plate and lead increase by four times, thereby make electric conductivity better, contact resistance is littler, and pressure drop reduces, and the temperature rise of pressing plate resistance is smaller or equal to the conductor resistance temperature rise, greatly reduce the power consumption of circuit itself, played energy-saving value-added effect.And solved repairing personnel's trouble and worry, reduced each other medium catalytic degree in parts and the operational environment in addition in the block terminal simultaneously, made the longer service life of block terminal, the tool promotional value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, be provided with a terminal block 2 in the casing 1.The first half of terminal block 2 is equipped with two RL1 type power fuse seats 4, and the lower end of terminal block 2 is adopted with set bolt 5 the silver-plated red copper pressing plate 6 of string data with eight opposite-compacting types of fourth officer is fixed on the terminal block 2, and pressing plate 6 is connected by lead 3 with fuse holder 4.Wherein, the upper end of casing 1 offers to street lamp wire hole 11, the lower end offer electric power incoming line hole 7, power outlet hole 8, earth connection portal 9 and earth connection enter hole 10.Wiring step when this block terminal is installed is as follows: open box body, each bolt, nut are unscrewed.The insulating barrier of electric power incoming line line end is peelled off, filled in the electric power incoming line hole, equally the insulating barrier of power outlet line end is peelled off, fill in the power outlet hole, screw nut.Again earth connection is connected to ground connection into and out of the line hole with said method.At last the not wired end of fuse holder is passed through to be connected with street lamp to the street lamp wire hole.
