Abstract
The utility model relates to a cam regulating type command controller, which comprises a cam component and a contact component. The contact component comprises a contact tip, a supporter and a braking member; an arc extinguishing chamber is arranged out of the contact tip; a pressure spring and a supported spring are respectively arranged on the upper part of a bridge type movable contact and the lower part of the bridge type movable contact; the braking member adopts a side moving type structure and the braking member is installed on the side of the arc extinguishing chamber, comprising an inserting plate and a spring; one end of the spring is pressed on the outside of the inserting plate; the cam component is provided with two convex points which are respectively a facade convex point and a side convex point. The utility model has the advantages of capability of simplification of controller structure, small size, reduction of abrasion of wearing parts, prolongation of mechanical durability and easy replacement of parts.
Description
The utility model relates to a kind of cam adjustment type master controller.
The main order of using is now controlled the contact supporter in the device and kept its brake component that cut-offs is to go here and there in groups to be contained on two steel axles, and two fastening rivetings of fixed head are fixed, therefore after the consumable accessory wearing and tearing, the on-the-spot very difficulty of changing, and owing to this structure is limit, contact close the spring force close spring reach 4 kilograms big, so the serious wear of contact and other wear-out part influences useful life of equipment.Said structure makes that this master controller is bulky, and is very heavy.Exchange master controller in addition by the air natural arc extinguishing, the direct current master controller is equipped with Petersen coil and arc-extinguish chamber, has more increased the volume of controller, and makes technology numerous and diverse further.
The purpose of this utility model provides a kind of cam adjustment type master controller of new structure, and it can make controller architecture simplify, volume-diminished, and the wearing and tearing that alleviate consumable accessory improve mechanical endurance, and the replacing ratio of part is easier to.
The purpose of this utility model is this realization: it comprises cam pack and contact assembly, it is characterized in that contact assembly is made up of Direct Action Type contact and supporter thereof and brake component, contact is equipped with arc-extinguish chamber outward, the bridge-type moving contact is equipped with compression spring up and down respectively and supports spring, and brake component adopts the side activated structure, is installed in the side of arc-extinguish chamber, it comprises a plate and spring, one end of spring is pressed in the plate outside, has two salient points on the cam pack, i.e. a front salient point and a side salient point.
If be used for dc controller, mounted in pairs has permanent magnet on the two side of arc-extinguish chamber.
After the utility model structurally improves, change the rotary type contact into volume-diminished 2/3 that the Direct Action Type contact can make controller, weight saving 1/2, contact are closed and to be closed required spring force and be reduced to 0.5 kilogram by original 4 kilograms, so be significantly improved mechanical endurance.Because set up with arc-extinguish chamber, and dc controller employing permanent magnet blowing-out arc, not only having strengthened the arc extinguishing ability, and further dwindled than original coil type structural volume, technology obtains simplifying.The utility model can directly be screwed on the housing that is installed in controller, thus install, dismounting is all convenient, for field service and change parts bigger convenience is provided.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is the general structure schematic diagram of a kind of specific embodiment of the utility model.
Fig. 2 is the structural representation of contact assembly among the embodiment shown in Figure 1.
Fig. 3 is that the A of Fig. 2 is to view.
Fig. 4 is a B-B cutaway view among Fig. 3.
Shown in Figure 1 is the structure chart that comprises the cam adjustment type master controller of five pairs of contacts and five groups of cams.As seen from the figure, it is made up of contact assembly 1 and cam pack 2, and each cam of cam pack is equipped with two salient points, i.e. a front salient point 17 and a side salient point 18.Contact assembly comprises contact and supporter 3 and brake component, and contact assembly is equipped with arc-extinguish chamber 5 outward, and contact is worked in arc-extinguish chamber.Contact is made up of fixed contact 7 and moving contact 8, fixed contact is fixedly mounted in the arc-extinguish chamber with screw 9, compression spring 10 is installed on the bridge type beam of moving contact, be equipped with below and support spring 11 and roller 12, brake component adopts side activated, and it is made up of plate 13 and spring 14, the arc-extinguish chamber side is installed with plate seat 15, plate promptly is inserted in the plate seat, and roller 4 is housed on the plate, and spring 14 is on little axle 16, the lower end is pressed in the outer rim of plate, work as cam rotation, when front contact goes to the summit, with cam 12 jack-up, length of spring compressed, the contact is disconnected, and at this moment the plate of brake component moves inward under the compressing of spring, blocks the edge of roller, it can not be fallen, cam is rotated further, and plate is outwards moved, and breaks away from roller 12, contact falls under the effect of spring, the closing of contact, five contacts are according to predetermined order folding, thus the sequential control of realization power consumption equipment.
If be used for dc controller, can on the two side of arc-extinguish chamber, give and bury permanent magnet 6 as shown in Figure 3, permanent magnet exists in pairs, is positioned at the both sides of contact.
The arc-extinguish chamber upper end has screw hole, can contact assembly be fixedly mounted in the controller with screw, carries for field service and has been total to bigger convenience.
Claims (2)
1, a kind of cam adjustment type master controller, it comprises cam pack and contact assembly, it is characterized in that contact assembly is made up of Direct Action Type contact and supporter thereof and brake component, contact is equipped with arc-extinguish chamber outward, and the bridge-type moving contact is equipped with compression spring up and down respectively and supports spring, brake component adopts the side activated structure, be installed in the side of arc-extinguish chamber, it comprises a plate and spring, and an end of spring is pressed in the plate outside, have two salient points on the cam pack, i.e. a front salient point and a side salient point.
