Description
Technical field
The present invention 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 6.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 small-sized with better creepage distance technical problem to be solved by the invention is to provide a kind of structure
High-power magnetic relay.
The technical scheme of the invention to solve the technical problem is: a kind of small high-power electromagnetic relay, packet
Include yoke, quiet contact group, dynamic contact group and bobbin, the bobbin includes spool, overhead gage and lower baffle plate, described
It is wound with coil on spool, isolation board is provided between the coil and the yoke, the lower baffle plate is provided with
Card slot is installed, the lower end of the isolation board is embedded in the installation card slot, and the upper end of the isolation board is located at described
The outside of overhead gage simultaneously upwardly extends, and 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.
The dynamic contact group includes movable contact spring, and the movable contact spring is provided with dynamic spring leading foot, on the movable contact spring
It is wholely set at least a piece of dynamic spring auxiliary leading foot with the dynamic spring leading foot side by side, the dynamic spring assists leading foot
The dynamic contact group leading foot of composition is mutually amplexiformed after folding with the dynamic spring leading foot.
The dynamic spring auxiliary leading foot is two panels.
The dynamic spring auxiliary leading foot rear end adjacent with the dynamic spring leading foot passes through rivet and the dynamic spring
Leading foot is fixed on together on 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；And product yoke foot is replaced by the way that product reed is carried out multilayer folding, directly progress foot extraction is guaranteeing that reed is transversal
In the case where area, product loaded line reduces bridge joint, reed and leading foot one, due to the on-state rate and heat dissipation performance of copper foot
It is better than iron foot, the stability of relay load path is improved, further reduced product temperature rise.
