Embodiment
For making the object, technical solutions and advantages of the present invention clearly, the present invention is described in more detail by the following examples.
first execution mode
In the first execution mode of the present invention, adjustment spring is fixed on a supporting mechanism away from one end of contactor main body, this supporting mechanism can in the contraction/direction of extension of adjustment spring, namely deformation side's upward sliding of spring is adjusted, the position that after being switched to " ON " state with fixed capacity contactor, pre-contact support is rebounded, and the position of dynamic conditioning capacitor switching contactor whole pre-contact module under being in " OFF " state.Thus, for the multiple contactor main body that parameter is different, during the state that ensure that capacitor switching contactor is switched to " OFF ", pre-contact is supported and the auxiliary mutual adhesive supported.
For convenience of description, first composition graphs 3 and Fig. 4 illustrate the situation of first embodiment of the invention when capacitor switching contactor is in " ON " state.Wherein, Fig. 3 is the front view that capacitor switching contactor is in its pre-contact module under " ON " state, and Fig. 4 is the stereogram that capacitor switching contactor is in its pre-contact module under " ON " state.
When capacitor switching contactor is switched to " ON " state by " OFF " state, main contact in contactor main body is supported to be with dynamic auxiliary to support the motion of direction shown in arrow in 2 to Fig. 3 by hook 5, now pre-contact supports that the adjustment spring 6 on 1 is close to one end of contactor main body, namely the end thereof contacts away from moving contact spring 7 is compressed to the standing part (not shown) in contactor housing, until consequent active force makes pre-contact support the permanent magnet 3 on 1 and the iron block 4 in auxiliary support 2 separately, that is, make this Liang Ge contact support sector divide to be separated from each other.After Liang Ge contact support sector divides and is separated from each other, pre-contact support 1 is rebounded in the opposite direction to side shown in arrow under the elastic restoring force of adjustment spring 6.
In pre-contact support 1, adjust spring 6 one end away from contactor main body, namely close to one end place of moving contact spring 7, be provided with and the supporting mechanism 8 adjusting spring 6 and be fixedly connected with, this supporting mechanism is specifically as follows supporting bracket etc.Due to this supporting mechanism in figure 3 perpendicular on the direction of paper in strip (this shape is more clearly illustrated in the diagram), in the process of thus rebounding in pre-contact support 1, this supporting mechanism 8 can owing to touching the fixed contact (not shown) of pre-contact module and stop motion, and then cause whole pre-contact to support 1 stop motion.Because the installation site of the fixed contact of pre-contact module is fixing in capacitor switching contactor housing, thus be in contact with it and the position that this supporting mechanism 8 of stop motion stops is fixing, the position that is pre-contact support 1 stops in rebound process is fixing.
Now, because adjustment spring 6 there is no any deformation, thus with pre-contact, this supporting mechanism 8 can support that the other parts of 1 contact, as in Fig. 4 shown in the situation in the dotted ellipse circle that marks, supporting mechanism 8 contacts with the upper ledge of forms 9.
Fig. 5 is the front view that in first embodiment of the invention, capacitor switching contactor is in its pre-contact module under " OFF " state, and Fig. 6 is the stereogram that in first embodiment of the invention, capacitor switching contactor is in its pre-contact module under " OFF " state.
When capacitor switching contactor switches back " OFF " state from " ON " state, auxiliary support 2 is moved in the opposite direction to side shown in arrow, when pre-contact support 1 and auxiliary support 2 are apart from time enough near, the permanent magnet 3 in pre-contact support 1 and the iron block 4 in auxiliary support 2 can attract each other and these two contact support parts be combined.Now, according to the parameter characteristic of contactor main body, auxiliary support 2 can continue to being the distance of L with the segment length of moving in the opposite direction of side shown in arrow along with contactor main body.Due to pre-contact support 1 with the marriage relation of auxiliary support 2, pre-contact support 1 also to be moved in the opposite direction identical distance L to side shown in arrow under the promotion of auxiliary support 2.But meanwhile, supporting mechanism 8 cannot move due to the contact with the fixed contact be fixed in capacitor switching contactor housing, therefore can in the forms 9 holding adjustment spring 6, there is relative to pre-contact support 1 relative sliding that length is L in this supporting mechanism, and this slip causes adjusting spring 6 and compressed identical length L.
When after auxiliary support 2 and pre-contact support 1 all stop motion, pre-contact module arrival capacitor switching contactor is in the stable state under " OFF " state, and the position at now pre-contact support 1 and auxiliary support 2 place is their point other initial positions.In this condition, adjustment spring 6 be have compressed a segment length L, and this segment length is equal with the distance L that auxiliary support 2 continues again to move after it combines with pre-contact support 1.
Now, because adjustment spring 6 there occurs certain deformation, thus this supporting mechanism 8 is separated from the other parts of pre-contact support 1, creates certain interval, as in Fig. 6 shown in the situation in the dotted ellipse circle that marks, supporting mechanism 8 has certain interval with the upper ledge of forms 9.
When capacitor switching contactor switches to " ON " state again, move under the drive that auxiliary support 2 is supported at the main contact of contactor main body to direction shown in arrow, pre-contact support 1 is also moved due to the marriage relation between auxiliary support 2 thereupon.Adjustment spring 6 stretches back original state in this process gradually, supporting mechanism 8 also departs from the contact condition with fixed contact afterwards, with pre-contact support 1 one arrow direction in the same way, until two contact support parts are separated from each other again under the active force of adjustment spring 6, pre-contact support 1 is rebounded again.
Described above is the state variation of pre-contact module in capacitor switching contactor stateful switchover process.As can be seen from foregoing description, adjustment spring is fixed on a supporting mechanism away from one end of contactor main body, because this supporting mechanism can touch the fixing fixed contact in position in contactor housing in the process of rebounding with pre-contact support, thus secure capacitor switching contactor be switched to " ON " state after the pre-contact support position of rebounding.Simultaneously, due to auxiliary be supported in the mutual adhesive of pre-contact support after pre-contact support still can be driven to continue motion one segment distance, thus ensure that, for the different multiple contactor main body of parameter, pre-contact support all can adhesive mutual to auxiliary support when capacitor switching contactor is switched to " OFF " state.
It will be appreciated by those skilled in the art that, when arranging position and the size of this supporting mechanism, can according to after be switched to " OFF " state when capacitor switching contactor, pre-contact support and auxiliary support between the characterisitic parameter of the most bad a kind of contactor main body of attracting state arrange, thus make it be applicable to the multiple contactor main body of different parameters simultaneously.
Such as, can determine after capacitor switching contactor is switched to " OFF " state from " ON " state, make auxiliary support to the shortest a kind of contactor main body (the most bad situation) of the distance of moving with direction of arrow rightabout.First assist the initial position of support to determine the initial position that pre-contact is supported according to during this contactor main body of use, and then support that the installation site of fixed contact in initial position and contactor case determines position and the size of this supporting mechanism jointly according to the pre-contact determined.Now, distance L can be 0 or very little value, and in other words when using this contactor main body, auxiliary support just supports adhesive or very short distance of only moving after adhesive with pre-contact with during the stop motion of contactor main body.Arrange according to such supporting mechanism, when making auxiliary other kind contactor main body supporting move distance longer, pre-contact support and the auxiliary mutual adhesive supported is guaranteed when just can be switched to " OFF " state at capacitor switching contactor, difference is only that, according to the auxiliary difference being supported in the distance L that the follow-up reforwarding of adhesive is moved, this supporting mechanism is by thereupon different for the length L of adjustment spring-compressed.
second execution mode
Fig. 7 is the front view of the pre-contact module of capacitor switching contactor in second embodiment of the invention.
Second embodiment of the invention, can support to arrange in 1 two adjustment springs 6 in pre-contact, be arranged at respectively on the position corresponding with two moving contact springs 7, and lay respectively at the both sides of permanent magnet 3, particular location as shown in Figure 7.Be similar to the description in first embodiment of the invention, two adjustment springs 6 are fixed on a supporting mechanism in the one end away from contactor main body respectively, and these two supporting mechanisms can be arranged on same level position in the figure 7.
When capacitor switching contactor switches to " ON " state, two supporting mechanisms 8 that the one end adjusting spring 6 with two is fixedly connected with all can touch the fixed contact of pre-contact module, thus cause pre-contact to support 1 stop motion.When capacitor switching contactor is switched to " OFF " state, two supporting mechanisms 8 also all can support 1 relative sliding occurs relative to pre-contact due to the contact with fixed contact in forms 9, thus the adjustment spring 6 corresponding to compression.
Owing to being provided with two supporting mechanisms in the permanent magnet both sides of pre-contact support, what make pre-contact be supported in capacitor switching contactor stateful switchover process stressedly balances more, is more conducive to the stable operation of equipment.
3rd execution mode
According to the 3rd execution mode of the present invention, an adjustment spring 6 also only can be set as in the first execution mode, but the right positions of permanent magnet 3 is in the figure 7 set, but not be arranged on as in the first execution mode in the leftward position of permanent magnet 3.The supporting mechanism etc. corresponding to this adjustment spring arranges all similar with the first execution mode.
Described above is three execution modes of the present invention.It will be appreciated by those skilled in the art that, according to the needs of industrial devices design, the adjustment spring of varying number can be provided with on the diverse location of pre-contact module, and according to mentality of designing of the present invention, arrange corresponding supporting mechanism to adjust spring with these and combine, to realize goal of the invention of the present invention, and reach relevant art effect.
According to the technique scheme of embodiment of the present invention, adjustment spring is fixed on a supporting mechanism away from one end of contactor main body, this supporting mechanism can slide in the contraction/direction of extension of adjustment spring, the position that after being switched to " ON " state with fixed capacity contactor, pre-contact support is rebounded, and the position of dynamic conditioning capacitor switching contactor whole pre-contact module under being in " OFF " state.Thus, during the state that ensure that capacitor switching contactor is switched to " OFF ", pre-contact is supported and the auxiliary mutual adhesive supported, ensure that the safe operation of contactor equipment; Meanwhile, the pre-contact module comprising this design can be made to be applicable to the different multiple contactor main body of parameter, to effectively reduce relevant equipment cost.
