Abstract
The utility model relates to a cam combined controller, comprising a cam component, a contact component, and a positioning switch device. The cam component has rotation type contact points and static contact points. The rotation type contact points are separately positioned between static contact points which are connected with two poles of a power supply. The cam component has convex points and concave points which can control the rotation type contact points and has positioning concave points which are corresponding to the positioning switch. The positioning switch is composed of a positioning ball, a positioning contact, a spring, and a regulating screw. The utility model can control the connection in parallel and connection in series of the branch circuit in circuit, the local or whole break, and the conversion of the sequence of each state. The utility model has the advantages of simple structure, good safety and accuracy, and convenient maintenance.
Description
The utility model relates to the box-like circuit control device of a kind of cam set.
Common contactor can only be controlled the break-make of a circuit, and plural circuit joint control can be used the combined type control device.Chinese patent application CN2110919U proposes, and uses cam adjustment type master controller can realize the sequential control of parallel circuit easily.But because each cam has only a front salient point that is used to control the closing of contact in this kind structure, thereby can only control each parallel circuit that is connected in parallel.
The purpose of this utility model provides a kind of cam grouped controls of new structure, and it can make in the circuit each parallel circuit control in certain sequence to form in parallel, series connection, local or whole off-state simply, exactly.
The purpose of this utility model be realize, combined camshaft, the corresponding locating device of contact assembly arranged on pedestal, it is characterized in that contact assembly comprises rotary type contact and stationary contact and supporter thereof, the stiff end of rotary type contact is an output terminal, cam is useful on the salient point and the concave point of control rotary type contact, and the location concave point corresponding with locating device arranged simultaneously.
To connecing positioning switch between the input end, it is by place kick at stationary contact, and distribution, moving contact, moving contact stage clip, spring set screw and static contact are formed, and the anchor point of cam is relative with the pilot hole of pedestal, and place kick is pressed into by spring, the power supply input.
The utility model utilizes the design feature of cam, realize conversion easily to parallel circuit parallel connection, series connection and other form, can control by a graded, owing to adopt positioning switch, promptly only in the control contact when determining the position cam orientation and closed power supply, both improved the reliability of security and control, also avoided the outage starting the arc to controlling the infringement of contact, its life-span is improved, then comparatively convenient to the maintenance of positioning contact.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
Fig. 1 is the general structure synoptic diagram of a kind of specific embodiment of the utility model.
Fig. 2 is that the A of Fig. 1 is to view (broken section).
Fig. 3 is a positioning switch modular construction synoptic diagram.
Fig. 4 is a cam combination curve synoptic diagram.
Fig. 5 connects circuit diagram.
The diagram 1 be depicted as comprise the cylindrical cam with three grooves 1. control respectively three rotary contacts 2. with two 4. foldings of stationary contact, be applied in the circuit shown in Figure 5.2. moving contact can connect power supply positive and negative electrode (alternating current is live wire, zero line) or disconnect, and 3. turning handle makes camshaft location concave point 1. corresponding with pedestal pilot hole 5., and 8. 7. place kick be pressed into concave point by spring; The positioning switch closing of contact.Set screw 6. suitably regulating spring 8. to moving contact pressure 9., be rotated further handle 3. then steel ball by promoting contact is disconnected, each anchor point makes circuit form five kinds of order status with the corresponding (see figure 4) of a kind of mode of connection, promptly disconnect, R1, R2 series connection R1 connects (R2 disconnection), and R2 connects (R1 disconnection), R1, R2 parallel connection, form sequential control simply, can be used for the circuit control that has level to change.
