A kind of magnetic latching relay is with pulling out sheet
Technical field
The utility model relates to the relay field, is specifically related to a kind of magnetic latching relay with pulling out sheet.
Background technology
Magnetic latching relay is a kind of new type of relay that grew up in recent years, also is a kind of automatic switch.The same with other electromagnetic relays, circuit is played automatic connection and cutting action.Difference is, the normally closed or normally open of magnetic latching relay is the effect that relies on permanent-magnet steel fully, and the conversion of its on off state triggers by the pulse electrical signal of certain width and finishes.The assembling of magnetic latching relay intraware (such as pedestal, movable contact spring sub-assembly and group of magnets component etc.) at present is many to be finished by assembly technologies such as welding, riveting dress and plastic packagings, the assembly technology complexity, waste time and energy, cause operating efficiency low, and the rework rate of product is higher.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provides the low magnetic latching relay of a kind of efficiency of assembling height, product rework rate with pulling out sheet, to solve the defective of existing assembly technology complex procedures and inefficiency.
The technical solution of the utility model is: comprise and pull out the sheet body, the groove that the two ends of body are respectively equipped with opening direction on the contrary and are respectively applied to peg graft with movable contact spring sub-assembly and group of magnets component.Namely finish assembling fast with movable contact spring sub-assembly and the grafting of group of magnets component respectively by pulling out sheet.
The utility model can further be improved to:
According to the structural design of existing movable contact spring sub-assembly and group of magnets component, the groove that pulls out on the sheet body is preferably designed for: one of them groove is used for pegging graft with the movable contact spring of movable contact spring sub-assembly, and another groove is used for pegging graft with the head of group of magnets component; Be the shape of groove and size should with the movable contact spring sub-assembly in movable contact spring and the profile of the head of group of magnets component coincide, reach the reasonable utilization of relay inner space.
For weight and the volume that alleviates relay integral body, pull out the sheet body and be preferably the sheet frame structure; For the reinforced frame stability of structure, pull out and preferably be provided with the reinforcement diagonal brace on the sheet body in addition.
Described magnetic latching relay is preferably 60A, 80A or 100A magnetic latching relay, facts have proved that the utility model is applied in best results on the magnetic latching relay of this model.
The utility model is simple in structure, reasonable in design, with low cost, by the grafting assembly technology, and can be fast with movable contact spring sub-assembly and the assembling of group of magnets component, time saving and energy saving, the safety and stability of assembling process; Can increase substantially the efficiency of assembling of magnetic latching relay, also greatly reduce the rework rate of product simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the confined state schematic diagram of a kind of embodiment of the utility model.
Among the figure: 1, pedestal; 2, movable contact spring sub-assembly; 3, pull out sheet (3.1 pull out the sheet body, 3.2 grooves, 3.3 reinforcement diagonal braces); 4, group of magnets component.
Embodiment
With reference to Fig. 1, a kind of magnetic latching relay is with pulling out sheet, pull out sheet body 3.1 and be provided with the sheet frame structure of strengthening diagonal brace 3.3 for two sides, pull out sheet body 3.1 two ends and be respectively equipped with the opposite groove of opening direction 3.2, the shape of groove and size design satisfy: one of them groove can be used in the movable contact spring sub-assembly in movable contact spring peg graft, another groove can be used in the head of group of magnets component and pegs graft.
Concrete assembling process is participated in Fig. 2, during assembling, earlier movable contact spring sub-assembly 2 is assemblied in pedestal 1 the inside, vertically places pulling out sheet 3 then, makes the movable contact spring in the recessed poor aligning movable contact spring sub-assembly 2 that wherein Open Side Down, cooperates assembling to go down by pegging graft; Then the head of group of magnets component 4 is aimed at and pulled out the groove that sheet 3 split sheds make progress, and cooperate assembling to get on by pegging graft.
Below only be an exemplary embodiments of the present utility model, it is particularly useful for 60A, 80A or 100A magnetic latching relay; Those skilled in the art can simply improve fully, modify on this basis; such as according to the practical set needs to pull out sheet body and groove shapes, size is simply adjusted; but all identical with the utility model substance, fall within the protection range of the present utility model equally.
