Abstract

The utility model is matched with various types of contactors and magnetic starters, belonging to the domain of the power frequency of a low voltage apparatus. The accepted basic principle is that a control circuit A-N is connected with an alternating current power supply. After a start button SB< 2 > is pressed, the current flows across a terminal A to a contacting coil KM through a switch QS, insurance FU< 1 >, a stop button SB< 1 >, a normally open point KM, and a thermal element FR to flow to a terminal N through insurance FU< 2 > to form the control circuit. The utility model has clear line on design, and moreover, the terminal is regularly led out, which causes the operator to conveniently know the condition of the basic work of the line. When once the problem appears, the fault point can be easily found, and then is maintained with reasonableness. A circuit board has small volume, and can save large amounts of wires; the cost is low, and the circuit board can be connected into the circuit of a contactor in series.

Description

A kind of universal electromagnetic switch terminal block

The utility model and various model contactor, the supporting use of magnetic starter belong to low-voltage electrical apparatus power frequency field.

At present, widely used contactor has a variety of, but all be unable to do without the energising or the outage of contactor coil, even same type contactor, its back panel wiring also has nothing in common with each other, comprise a plurality of loops for the distribution board that a plurality of contactors are arranged, the own distribution of Field Force because operation is not good at, often makes contact loosening, cause overheated or virtual connection, simultaneously the trend of connection and line is staggered mixes, and none is established rules then, and all with the terminal board wiring, in case break down, search line fault to the maintenance personal and bring very big difficulty.

The purpose of this utility model is to provide a kind of universal electromagnetic switch terminal block, and it and contactor, the supporting use of magnetic starter make contactor and terminal distribution clear, do not disturb mutually, and lead connects fasteningly, has replaced original terminal board.

The utility model is achieved in that it by power supply terminal A, and N, pyrogen part FR, often make war KM, contact coil KM, insurance FU, binding

post

1,2,3,4,5, casing 6, case lid 7, case lid hole 8 formed.Its basic principle is that control loop A-N connects the 380V AC power, presses starting button SB ₂After, electric current is through terminal A, again through switch QS, insurance FU ₁, stop button SB ₁, often make war KM, thermal element FR, to contact coil KM, through insurance FU ₂, arrive terminal N at last and constitute control loop.This control loop A-N also can connect 220 AC power.This terminal block major loop 380V input current is through terminal a, insurance FU ₁, come out from thermal element FRc to thermal element FRb, draw binding post 1; KMd comes out from normal battle, can draw binding post 2; KMe comes out from normal battle, draws binding post 3, returns contact coil KMf again from binding post 3 and constitutes the loop; KMg comes out from the contact coil, draws binding post 4; At last from binding post 5 through the insurance FU ₂, get back to power supply terminal n, each draws binding post all label or color, to show difference, whole major loop all is fixed on casing 6 bases, and each contact all adopt the welding or screw fastening, case lid 7 is buckled on the casing 6, and respectively there is a case lid hole 8 at case lid 7 two ends, expose safety handle, bring convenience to regular maintenance, the binding post 1,2,3 of drawing, 4,5 are installed on the square template that casing 6 outer walls are connected to.Terminal block also can be drawn a plurality of binding posts as required again.

The utility model has adopted various circuits separately in design, and leading-out terminal regularly, makes operating personnel understand the groundwork situation of circuit easily, in case go wrong, is easy to find the fault point, is properly keeped in repair.Contact adopts welding and screw fastening, perhaps saves contact, virtual connection can not occur or becomes flexible and cause the overheated generation of lead.This terminal block volume is little, can save a large amount of leads, and cost is low, and directly serial connection is gone in the contactor loop easily, has saved terminal board, and promote the use of at the scene of being easy to.

Accompanying drawing 1 is circuit theory diagrams of the present utility model.

Accompanying drawing 2 is a circuit connection diagram of the present utility model.

Accompanying drawing 3 is a stereogram of the present utility model.

Below in conjunction with accompanying drawing the utility model is illustrated, in circuit theory diagrams shown in Figure 1, presses start button SB ₂After, contact coil KM gets electric, main contacts KM closure, and normally open contact KM closure forms a control loop; This terminal block major loop 380V input current is through terminal a, insurance FU ₁, come out from thermal element FRc to thermal element FRb, draw binding post 1; KMd comes out from normal battle, can draw binding post 2; KMe comes out from normal battle, draws binding post 3, returns contact coil KMf again from binding post 3 and constitutes the loop; KMg comes out from the contact coil, draws binding post 4; At last from binding post 5 through the insurance FU ₂, get back to power supply terminal n, each draws binding post all label or color, to show difference, whole major loop all is fixed on casing 6 bases, and each contact all adopt the welding or screw fastening, case lid 7 is buckled on the casing 6, and respectively there is a case lid hole 8 at case lid 7 two ends, expose safety handle, bring convenience the binding post 1,2 of drawing to regular maintenance, 3,4,5 are installed on the square template that casing 6 outer walls are connected to, and whole box body 7 bases are fixed on the distribution board.Suitable lead is 1.5mm ²The plastics copper cash insures and is 5A, withstand voltage 380V/220V, and terminal is done with copper, and casing 7 and sealing lid are made with insulating material, by flat, plastic parcel lead.Control loop also can connect the 220V AC power, presses Fig. 1 dotted line and connects.
