Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
For simplicity of the drawing, only the parts relevant to the present invention are schematically shown in each drawing, and they do not represent the actual structure thereof as a product.
Example 1
As shown in fig. 1 and 2, the present embodiment discloses a reversing switch type magnetic latching relay, comprising: base 100, terminal assembly, direct-push magnetic latching drive, iron core assembly 400, moving contact 300, and contact support 410.
The base 100 is a housing structure, which can accommodate the internal components of the relay therein, and a cover is covered on the base 100. The terminal assembly is mounted on the base 100 with the stationary contact 220 mounted thereon, and is electrically connected to the incoming line and the outgoing line. The iron core assembly 400 includes an iron core 430 and a contact support 410, the contact support 410 is connected with the iron core 430, the iron core 430 slides linearly along a coil skeleton 530 of the direct-push type magnetic latching driving device under the action of the direct-push type magnetic latching driving device, the direct-push type magnetic latching driving device is a common structure in the prior art, the action mechanism is that a magnetic field is formed by changing current, and the magnetic field force drives the iron core 430 to do linear reciprocating motion.
The contact support 410 is a frame structure, and is driven by the iron core 430 to reciprocate linearly therewith. The movable contact 300 is provided with a movable contact 330, the movable contact 330 is arranged opposite to the fixed contact 220, and the terminal assembly is electrically connected with the movable contact 300. The moving contact 300 is installed in the contact holder 410, and is limited by the contact holder 410 in the sliding direction of the core. That is, the contact support 410 may drive the moving contact 300 to move, and at the same time, the moving contact 300 and the contact support 410 may be kept relatively stationary, or a certain stroke, that is, a floating limit, may be provided on the contact support 410. In both cases, the moving contact 300 can be driven by the contact support 410 to slide linearly, so as to realize the on-off action with the stationary contact 220.
Further preferably, when the moving contact 300 is floatingly restrained by the contact holder 410, a reaction spring 600 may be added between the moving contact 300 and the iron core assembly 400. Referring to fig. 2, when the iron core assembly 400 moves upward until the stationary contact 220 is just in contact with the movable contact 330, the iron core 430 is spaced apart from the upper yoke 500 by a certain distance, and at this time, the iron core assembly 400 may continue to move upward, and the movable contact may not continue to move upward. Since the contact support 410 is displaceable relative to the movable contact 300, the iron core assembly 400 will not be immediately limited by the movable contact 300 and will continue to move upwards to compress the reaction spring 600 until the iron core 430 is attracted to the yoke 500. At this time, the reaction spring 600 is in a compressed state, and its reaction force can act on the abutting surface of the stationary contact 220 and the movable contact 330 to close and fasten them, so as to increase the reliability of the structure. Meanwhile, after long-term use, the contact surface of the movable contact and the stationary contact also has the problem of surface abrasion, and the counter-force spring 600 can also play a role in compensation, so that the movable contact 330 can be closed with the stationary contact 220 in the stroke of the iron core 430.
For example, refer to fig. 2 and 5. The moving contact 300 comprises a guide part 310, an overhanging part 320 and a mounting part 330, wherein the guide part 310 can slide along a track formed by surrounding the contact support 410 in the moving contact to ensure the alignment and the matching of the moving contact 330 and the fixed contact 220; the overhanging portion 320 is connected to the guide portion 310, and extends to be disposed opposite to a side end surface of the contact support 410 facing away from the movable contact. The reaction spring 600 is located between the mounting portion 330 and the core assembly 400. Further, the moving contact 300 includes two overhanging portions 320 and two guiding portions 310, which are respectively located at two sides of the mounting portion 330, that is, one guiding portion 310 and one overhanging portion 320 are located at one side of the mounting portion. The two overhanging portions 320 may further be connected by wires. Of course, the number of overhanging portions and guiding portions may be greater, such as 4 and 8.
It should be noted that, in fig. 1, the terminal assembly includes a wire inlet terminal 210 and a first wire outlet terminal 200, a stationary contact 220 is disposed on the wire outlet terminal 200, the wire inlet terminal 210 is connected to an overhanging portion 320 of a moving contact 300 through a wire, and the reciprocating motion of the iron core assembly implements opening and closing actions of a set of stationary contacts and moving contacts.
Similarly, as shown in fig. 3, 4 and 6-b, the reversing switch type magnetic latching relay comprises two oppositely arranged stationary contacts 220, which are respectively arranged on the first outgoing line terminal 200 and the second outgoing line terminal 201, correspondingly, two movable contacts 330 are arranged on the contact support 410 in a back-to-back way, and the outer extending contact support 410 is respectively arranged opposite to the stationary contacts 220, so that the reciprocating motion of the iron core assembly can realize the opening and closing actions of the two groups of movable and stationary contacts, and the structure can play a role of a reversing switch. The movable contact 300 can be designed as described above, and the contact support 410 is adapted to accommodate two opposite movable contacts 300, and the overhanging portion 320 extends to a side end surface opposite to the movable contact on the contact support 410, opposite to the side end surface, opposite to the corresponding movable contact, as shown in fig. 3 and 4, and the reaction spring 600 is located between the two movable contacts 300.
Example two
On the basis of the first embodiment, referring to fig. 6-a and 7-a, which are core assembly structures suitable for the magnetic latching relay shown in fig. 1 and 2, the core assembly 400 further includes a connecting rod 420, the contact support 410 is a plastic package, one end of the connecting rod 420 is fastened by being sealed in the contact support 410, the other end of the connecting rod is fastened in a mounting hole 431 on the core 430, and for example, the connecting rod 420 is fastened by cold heading in the mounting hole 431, and other riveting connection manners can be adopted instead. Namely, the molding process of the iron core assembly 400 is as follows: firstly, one section of the connecting rod 420 is placed in the mounting hole 431 of the iron core 430, then the connecting rod 420 is fixed through cold heading, after the completion of the plastic package forming of the contact support 410, the connecting rod 420 is wrapped in the plastic package contact support 410, and the fastening is completed.
For example, referring to fig. 5, the connecting rod 420 is in a shape of a "T", a "horizontal" is a fixture 421, and a "vertical" is a vertical rod; contact support 410 includes a connecting end face adjacent to one side of core 430; the latch 421 is molded into the connecting end surface. The structure of one clamping block 421 enhances the connection strength of the connecting rod 420 and the contact support 410, and ensures the reliability of the synchronous movement of the connecting rod 420 and the contact support 410. Of course, the connecting rod 420 may further include more than 1 latch structure thereon.
Preferably, a groove 432 is provided on the outer circumferential surface of the core 430, and the groove 432 is adapted to the position of the connecting rod 420. The reason for the groove structure is that the cold heading or other riveting process will apply a mechanical force to the outer ring surface of the iron core, which will inevitably cause a change in the shape of the outer ring surface of the iron core, and in order to prevent the change in the shape from affecting the mating dimension of the outer ring surface of the iron core, and thus affecting the accuracy of the sliding motion thereof, a groove 432 may be formed in the outer ring surface at a position corresponding to the mounting 431. The core assembly structure of fig. 6-b and 7-b is suitable for use in the commutating switched magnetic latching relay of fig. 3.

The magnetic steel 520 is detachably connected to the enclosure frame through the magnetic steel support 510, so that the magnetic steel 520 is convenient to detach and adjust when the magnetic force needs to be adjusted. The magnetic steel bracket 520 is also provided with a disassembly hole 513 for disassembly and assembly.
