Specific embodiment
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, control is illustrated below The specific embodiment of the present invention.It should be evident that the accompanying drawings in the following description is only some embodiments of the present invention, for For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings Attached drawing, and obtain other embodiments.
To make simplified form, part related to the present invention is only schematically shown in each figure, their not generations Its practical structures as product of table.
Embodiment one
As depicted in figs. 1 and 2, the present embodiment discloses a kind of reversing switch formula magnetic latching relay, including:Pedestal 100, end Sub-component, direct-push magnetic keep driving device, iron core assembly 400, moving contact 300 and contact to support 410.
Pedestal 100 is a shell structure, can accommodate the internal components of relay portion in the inner, above be stamped a cover by pedestal 100 lids close.Terminal assemblies are mounted on pedestal 100, are installed with stationary contact 220 thereon, terminal assemblies are electrically connected with inlet wire and outlet It connects.Iron core assembly 400 includes iron core 430 and contact supports 410, and contact supports that 410 connect with iron core 430, in direct-push magnetic Under the action of keeping driving device, iron core 430 keeps 530 straight line of coil rack of driving device to slide along direct-push magnetic, directly pushes away Formula magnetic keeps the common structure that driving device is the prior art, and the mechanism of action forms magnetic field, magnetic field force by variable-current Driving iron core 430 does straight reciprocating motion.
It is tower structure that contact, which supports 410, and straight reciprocating motion is done with it under the drive of iron core 430.Moving contact Movable contact 330 is installed on 300, movable contact 330 is oppositely arranged with stationary contact 220, and terminal assemblies are electrically connected with moving contact 300. Moving contact 300 is installed in contact and supports in 410, and the 410 direction upper limits slid in iron core are supported by contact.Namely contact is supported 410 can drive moving contact 300 to move, while moving contact 300 supports that 410 can both keep opposing stationary with contact, can also Support there is certain stroke namely floating type limiting on 410 in contact.Moving contact 300 can be by both cases Contact supports 410 to drive straight line sliding, realizes the on-off action with stationary contact 220.
It is further preferred that when moving contact 300 supports 410 floating type limiting by contact, it can be in moving contact 300 and iron core Reaction spring 600 is added between assembly 400.With reference to shown in Fig. 2, when iron core assembly 400 moves up to stationary contact 220 with moving During 330 exactly in contact with of contact, yoke 500 of the iron core 430 apart from top also has a certain distance, and iron core assembly 400 may be used also at this time To continue up, moving contact can not continue to move up.And due to contact support 410 can opposite 300 displacement of moving contact, then iron core Assembly 400 will not immediately be limited by moving contact 300 and will continue to move up compression reaction spring 600, until iron core 430 is attracted to magnetic On yoke 500.Reaction spring 600 is in confined state at this time, and bounce can act on stationary contact 220 and movable contact 330 It is made to be closed fastening on interface, increases reliability of structure.Meanwhile contact of the movable contact with stationary contact after long-term use Face also will appear the problem of surface abrasion, and reaction spring 600 can also play the role of compensation, in the stroke for ensureing iron core 430 Movable contact 330 can be closed with stationary contact 220.
Illustratively, with reference to shown in Fig. 2, Fig. 5.Moving contact 300 includes guide part 310, over-hang part 320 and mounting portion 330, guide part 310 can support 410 to enclose inside it along contact and set the track to be formed sliding, to ensure movable contact 330 and stationary contact Point 220 to just coordinating;Over-hang part 320 is connect with guide part 310, and is extended to and supported on 410 backwards to described dynamic tactile with contact One side end face of point is oppositely arranged.Reaction spring 600 is between mounting portion 330 and iron core assembly 400.Further, it moves and touches First 300 include two over-hang parts 320 and two guide parts 310, respectively positioned at the both sides of mounting portion 330, i.e. a guide part 310 and an over-hang part 320 be located at the side of mounting portion.Two over-hang parts 320 can further be connected by conducting wire.It of courses, The quantity of over-hang part and guide part can be more, for example quantity is 4,8.
It should be noted that terminal assemblies include 210 and first outlet terminal 200 of input terminal, stationary contact 220 in Fig. 1 It is arranged on outlet terminal 200, input terminal 210 is connect with the over-hang part 320 of moving contact 300 by conducting wire, iron core assembly Moving back and forth realizes the on-off action of one group of stationary contact and movable contact.
Similar therewith, as shown in Fig. 3, Fig. 4 and Fig. 6-b, reversing switch formula magnetic latching relay includes two and sets relatively The stationary contact 220 put is respectively installed on the first outlet terminal 200 and the second outlet terminal 201, correspondingly, contact supports 410 On also backwards to setting there are two movable contact 330, and the outer contact that stretches out supports that 410 are oppositely arranged with stationary contact 220 respectively, iron core The reciprocating motion of assembly can realize the on-off action of two groups of dynamic and static contacts, this structure can play the role of reversing switch.Its The structure of moving contact 300 can be according to above-mentioned design, and what need to only be adapted to supports contact 410 changes are that can house two reversely Moving contact 300, with reference to shown in Fig. 3 and Fig. 4, over-hang part 320, which is extended to, to be supported on 410 to contact backwards to the corresponding movable contact One side end face is set corresponding thereto, and reaction spring 600 is located between two moving contacts 300.
Embodiment two
