Abstract
The invention relates to a power breaker for switching an electric circuit in which the force applied by the movement of a rocker, a rocker lever or a finger-grip knob can be transmitted via a latching mechanism to a mobile contact piece which switches the circuit. The invention aims to avoid the expensive designs of various latching mechanisms. To this end, the latching mechanism (1) has identical basic equipment for different sizes of power breakers. Said equipment can be adapted to different size requirements by exchanging, omitting or adding of different individual components.
Description
The present invention relates to a kind of power switch that is used to connect power circuit, can be delivered to by switch lock on the contact block mobile, that connect circuit in the power that is produced by fork, rocking bar or knob motion on this switch.
The power switch that is used to connect different rupturing capacities is manufactured with different specifications.Owing to the overall structure of this power switch of reason on physical technique or the process technology, for example the position of switch lock or different releases depend on maximum switch power basically.According to order person's demand, according to the design application and according to manipulation form (by the manual control or the remote operation of fork, rocking bar or knob), the manipulation of switch should realize in operating surface as much as possible in the heart in addition.
In order to coordinate different physical dimensions, suggestion is once adopted and is had the different switch locks of the operating element of special coupling mutually.Such shortcoming is that this special switch lock is very expensive.
DE3606508C2 discloses a kind of switching mechanism that is used for the house wiring electric device, such switching mechanism can be selected as push-button switch, button, seesaw type switch or flip button, it handles the contact spring of changing by the triggering element that adopts a rocking bar shape between two position of the switch.This triggering element effectively is connected with a push rod of operating element, makes push rod impinge upon on the rocking bar face when each the manipulation and make thus to trigger the location deflection of element to its opposite.This switching mechanism is equipped with the adjustment element, triggers element not only with contact spring but also concur with adjustment element in the switch case at this, and this adjustments element can be rotatably set in the triggering element and contact spring moves freely between the end.Switching mechanism can be changed selectively by adjusting element, this switching mechanism or can or can be used as button as switch.But can not coordinate the power switch of different structure size by this switching mechanism.
Disclose a kind of electric power disconnect by G9001424.3U1, this disconnect has a control button turnover or that slidably adjust, to be used for handling two moving contacts selectively.This control button can reciprocating motion between an original position and two mutual cohesive positions, original position is corresponding with the open position with respect to two moving contacts of fixed contact, and two positions that are connected mutually are used for one or two moving contact and contact with fixed contact.Cooperate the position that is used for determining control button with the contact with the coefficient elasticity retaining mechanism of control button, constitute by a flexible tongue that is connected with the fixed contact bearing at this this flexible retaining mechanism.Although this known disconnect has different operating mechanisms, the different structure size that it equally can not the coordinating power switch.
The objective of the invention is to, the power switch of the described type of preface is made like this, that is, make it to avoid the expensive structure of different switch locks.
The objective of the invention is to realize by a kind of power switch that is used to connect power circuit, on this switch, pass through fork, the power that rocking bar or knob motion are produced can be sent to mobile by switch lock, connect on the contact block of circuit, switch lock has for all identical basic outfit of the power switch of different structure size, it is characterized in that, form by whole switch lock for the basic outfit that the different structure size is all identical, this switch lock is arranged in parallel by two basically, the thin plate that constitutes housing constitutes, one pawl lever and one acts on mobile, connection lever on the contact block in connection loop is rotatably supported between these two thin plates, between two thin plates, also be provided with a gantry post, this gantry post is used for promptly being used for fork according to the selected operating element of physical dimension, rocking bar or gear fork.This basic outfit is by changing, remove or add the requirement that different single parts can be adapted to the different structure size.
According to an improvement design of the present invention, fork can be replaced with rocking bar.
For engagement that realizes coupling gear and the rigid connection of realizing handle thus, improve design according to of the present invention another, fork can be replaced with the gear fork.This outside lever can be replaced with the gear fork that has coupling gear and knob.
In order to coordinate different installation sites, improve design according to of the present invention another, between gear fork and coupling gear, can insert a power transmission shaft.
Advantage of the present invention mainly is, can avoid the special processing of expensive different switch locks, can be with the power switchs that are fit to, can cheap basic outfit of making be applied to different sizes with relatively large number of packages.
The present invention is described in further detail by the accompanying drawing illustrated embodiment below, in the accompanying drawing:
Fig. 1 is the sketch of the power switch of three different sizes,
Fig. 2 is the control surface sketch of the power switch of three different sizes,
Fig. 3 is the three-dimensional view that has the switch lock of fork;
Fig. 4 is the three-dimensional view that has the switch lock of gear fork,
Fig. 5 is the three-dimensional view that has the switch lock of gear fork, coupling gear and knob,
Fig. 6 is the three-dimensional view that has the switch lock of gear fork and power transmission shaft,
Fig. 7 is the three-dimensional view that has the switch lock of gear fork, power transmission shaft, coupling gear and knob.
The power switch of three different sizes shown in Figure 1 has different short circuits and overload release 7,8, switch lock 1 and the operating element that is having identical basic outfit wherein, be between fork 2 or the knob 4, do not insert or insert different single parts, as have the gear fork 3 of coupling gear 5 or have the power transmission shaft 6 of coupling gear 5.
Fig. 2 illustrates the control surface sketch of the power switch of three different sizes, and is wherein just enough as operating element with a fork or rocking bar 2 in the structure of minimum, then has the knob 4 that is applicable to more energetically for two bigger structures.
All has identical basic outfit at the switch lock shown in Fig. 3 to 7.These are equipped with basically substantially is made up of following parts: the thin plate 9 of two formation housings that are arranged in parallel, 10, the torsion spring 16 that between two thin plates, exposes, only lock 17 and other single parts, connect two thin plates 9,10 bearing pin 11,12, and be bearing in rotating pawl lever 14 and switch lever 15 on the bearing pin.
Another bearing pin 13 is used as gantry post equally in Fig. 3 to 7, but is used for different single parts, promptly is used for fork or rocking bar 2 in Fig. 3, is used for gear fork 3 in Fig. 4 to 7, and this gear fork is by coupling gear 5 and knob 4 engagements in Fig. 5.In Fig. 6 bearing pin 13 be used as gear fork 3 and with the gantry post of the power transmission shaft 6 of its coupling, and in Fig. 7 an additional coupling gear 5 and knob 4 of being provided with.
