Abstract
The utility model relates to a multipurpose combined quickly-switching-off contact box, comprising an arc-extinguishing housing, a guide element and a connecting piece. The utility model is characterized in that the connecting piece is provided with a guide hole which is matched with the guide element, both sides of the guide element and the connecting piece are provided with baroclinic return springs, the lower end of the guide element is connected with a pressure spring, and the front, the back and the side surfaces of the upper end of the guide element are respectively provided with installing and connecting holes. The utility model has the advantages of high speed of switching off, good arc-extinguishing effect, high electric service life, large current capacity, simple assembly, quick assembly, multiaspect installation and strong versatility.
Description
The utility model relates to the electric appliance component of low-voltage electrical apparatus control circuit, specifically a kind of multipurpose combined quick-break contact box.
The contact box is the important electric appliance component of low-voltage electrical apparatus control circuit, and it is directly connected to the connection and the disjunction of control circuit.Present various low-voltage electrical apparatus can not disconnect rapidly as the moving contact and the fixed contact of employed contact boxes such as master controller, limit switch, and arc quenching effect is poor, and electric life is low, can not exchange use.Especially on the electrical equipment control of change in location, the connection of push button contact and disjunction, be subjected to the convex-concave variable effect of cam big, when the height of convex-concave does not reach rated value, the push button contact can not effectively be connected and disjunction, always for some time under, adjust very difficulty like Tong Feitong, like disconnected non-disconnected state.Sensitive switch is a quick-break switch, but its capacity is little, must transform by relay, and the scope of application is little, can not use in the DC control circuit.
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of multipurpose combined quick-break contact box is provided.
The purpose of this utility model is achieved in that it comprises arc-extinguish chamber, guide, plate, moving contact, goes up fixed contact, following fixed contact.It is characterized in that being shaped in the plate pilot hole, pilot hole matches with guide, is equipped with the return spring that baroclines between guide both sides and the plate; Guide lower end and stage clip join, and front, back, the side at place, guide upper end are shaped on the installation connecting hole respectively.
Above-mentioned contact box is characterized in that the guide both sides are shaped on to put the spring nest, is shaped in the pilot hole of plate and puts the spring boss.
The utility model advantage is: moving contact and fixed contact break-make speed are fast, and arc quenching effect is good, the electric life height, and current capacity is big, product simple and convenient assembly, quick; Can multi-facetedly install, highly versatile, the scope of application is extensive.Reduce the development and Design work of contact box kind effectively, saved a large amount of frock manufacturings and produced input, reduced cost.In the electrical equipment control upper contact that the is used for change in location disjunction immediately that puts in place.
The utility model details provides by following examples and accompanying drawing.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Fig. 2 is the structural representation of plate among Fig. 1.
By Fig. 1-shown in Figure 2, the contact box mainly by arc-extinguish chamber 1, guide 3, stage clip 9, the return spring 4 that baroclines, plate 7, moving contact 6, go up fixed contact 5, fixed contact 8 etc. is formed down.Arc-extinguish chamber 1 is two butt joints of middle branch composite type one-time formed process conditions of high-strength engineering plastic.Be shaped on pilot hole 11 in plate 7, pilot hole 11 matches with guide 3, is equipped with the return spring 4 that baroclines between guide 3 both sides and the plate 7; Guide 3 lower ends and stage clip 9 join, and front, back, the side at place, guide 3 upper end is shaped on respectively installs connecting hole 10; Guide 3 both sides are shaped on puts spring nest 2, is shaped in the pilot hole 11 of plate 7 and puts spring boss 12, and return spring 4 one ends that barocline are connected to be put in the spring nest 2, and the other end is connected to be put on the spring boss 12.Moving contact 6 is fixed in the plate 7.Under normal condition, stage clip 9 is supported guides 3 upwards, and the return spring 4 that baroclines is exerted pressure to plate 7, makes its moving contact 6 be pressed on down on 8 of the stationary contacts moving contact 6 and following fixed contact 8 connections.When guide 3 is applied in external force, it is descending to overcome stage clip 9 counter-forces, barocline return spring 4 along with guide 3 moves down, the return spring 4 that baroclines is compressed, and pressure increases between the moving contact 6, when the pilot hole 11 of return spring 4 by plate 7 that barocline is forced through moving contact 6 horizontal midline positions, and the buffer brake abrupt release of the return spring 4 that baroclines, make moving contact 6 go up bullet rapidly and be pressed on, reach quick connection with last fixed contact 5; After guide 3 suffered external force are eliminated, because stage clip 9 effects, barocline return spring 4 with moving on the guide 3, when the return spring 4 that baroclines is crossed moving contact 6 horizontal midline positions by the pilot hole 11 of plate 7, the return spring 4 that baroclines is connected 6 times bullets of moving contact and following fixed contact 8 rapidly, reaches the purpose of quick-break.Select as required during use the contact box in the front, back, the set installation connecting hole 11 in side.
