Abstract
The utility model discloses a kind of small high-power electromagnetic relays, including yoke and bobbin, bobbin includes spool, overhead gage and lower baffle plate, coil is wound on spool, isolation board is provided between coil and yoke, lower baffle plate is provided with installation card slot, in the lower end insertion installation card slot of isolation board, the upper end of isolation board is located at the outside of overhead gage and upwardly extends, isolation board lower end is fixed with lower baffle plate, advantage is by fixing the lower baffle plate of the lower end of isolation board and bobbin, the upper end of isolation board can be arranged in the outside of overhead gage and upwardly extended, the creepage distance of relay can be greatly improved in this way, for the relay of same model, do not change size it is not for dispensing glue under the premise of, creepage distance maximum can double.
Description
Technical field
The utility model relates to a kind of relays, more particularly, to a kind of small high-power electromagnetic relay.
Background technique
Electromagnetic relay generally includes magnetic circuit system and contact system, and magnetic circuit system includes yoke, and contact system includes quiet
Contact group and dynamic contact group, structure are as depicted in figs. 1 and 2.The miniature electro-magnetic relay includes a bobbin, on bobbin
Be provided with the coil of enameled wire composition, loaded line is to be welded or be riveted on yoke by reed, coil and yoke it
Between be provided with isolation board.And this structure is a kind of current effective way for increasing product creepage distance.The structure of isolation board
As shown in Figure 3.From in Fig. 1 and Fig. 2 it will be seen that current isolation board is fixed between the baffle at spool both ends,
Common practice is slot to be arranged on baffle, and isolation board ends are inserted into respectively in the slot of two side baffles and are fixed.
This structure is the problem is that when needing to further increase creepage distance, usually in the intersection of isolation board and baffle point
Glue, this operational sequence increases, complicated for operation.
Summary of the invention
It is simple and with better creepage distance the technical problem to be solved by the utility model is to provide a kind of structure
Small high-power electromagnetic relay.
The technical scheme of the invention to solve the technical problem is: a kind of small high-power electromagnetic relay, packet
Yoke and bobbin are included, the bobbin includes spool, overhead gage and lower baffle plate, is wound on the spool wired
Circle, is provided with isolation board between the coil and the yoke, the lower baffle plate is provided with installation card slot, it is described every
In lower end insertion from the plate installation card slot, the upper end of the isolation board is located at the outside of the overhead gage and upward
Extend, the isolation board lower end is fixed with the lower baffle plate.
The side of the lower baffle plate is provided with fixed jack, and fixed insert is provided on the outside of the isolation board lower end
Hook, the fixation inserting hook are inserted into the fixed jack.
The upper end of the isolation board upwardly extends concordant with the upper end of the yoke.
Compared with the prior art, the advantages of the present invention are as follows by consolidating the lower baffle plate of the lower end of isolation board and bobbin
It is fixed, the upper end of isolation board can be arranged in the outside of overhead gage and upwardly extended, climbing for relay can be greatly improved in this way
Electrical distance, for the relay of same model, do not change size it is not for dispensing glue under the premise of, creepage distance maximum can increase
One times.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art；
Fig. 2 is the schematic perspective view of prior art isolation board；
Fig. 3 is the structural schematic diagram of the utility model；
Fig. 4 is that the utility model removes the schematic perspective view after yoke；
Fig. 5 is the schematic perspective view of the utility model bobbin；
Fig. 6 is the schematic perspective view of the utility model isolation board.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Embodiment: as illustrated in figures 3-6, a kind of small high-power electromagnetic relay, including yoke 1 and bobbin 2, coil
Frame 2 includes spool 21, overhead gage 22 and lower baffle plate 23, is wound with coil 24 on spool 21, sets between coil 24 and yoke 1
It is equipped with isolation board 3, lower baffle plate 23 is provided with installation card slot 25, and the lower end insertion of isolation board 3 is installed in card slot 25, isolation board 3
Upper end is located at the outside of overhead gage 22 and upwardly extends concordant with the upper end of yoke 1, and the side of lower baffle plate 23 is provided with fixed insert
Hole 26, fixed inserting hook 31 is provided on the outside of 3 lower end of isolation board, and fixed inserting hook 31 is inserted into 26 in fixed jack.
