Description

Switch tripping device without fuse

The utility model relates to a kind of switch, particularly a kind of switch tripping device without fuse.

With reference to Fig. 1, shown in Figure 2, general switch tripping device without fuse commonly used, it is configured to an electric copper output 90, these electric copper output 90 1 terminations are provided with a coil 91 made of copper, this coil 91 is wrapped in a body 92 peripheries, fill with the oil body 93 of thick shape in this body 92, in body 92, then installed a bar magnet 94, pressed a spring 95 on this bar magnet 94, these spring 95 other ends are resisted against on oil seal cover 96 inwalls that are covered with body 92 openings, and are provided with support 97 at body 92 other excessive places, and this support 97 has the power lead 98 that is connected with coil 91, then be rotatably connected to a push pedal 99 on support 97 tops, these push pedal 99 other brake mechanisms 9 that are provided with.

That above-mentioned this device construction is not only assembled is time-consuming, cost is expensive, and in use, because of having rated current, need flow through coil, the high temperature that coil 91 is produced just can conduct to the oil body 93 in the body 92, make its thick shape be fused into mobile shape, make bar magnets 94 buoyance lift upwards slowly in the body 92 simultaneously, abutted on the oil seal cover 96 by the magnetic force absorption that bar magnet 94 produces on one side until the push pedal on the body 92 99, and then push pedal 99 another sides are pressed against on the brake mechanism 9, jump out of the origin-location to brake mechanism 9 bullets are taken off, thereby reach the purpose of cutting off the electricity supply.But; bar magnet 94 in the coil 91 often has error slightly because of processing; or because of the precision of material not enough; and when floating as making progress fast moment at specified electricity; and then brake mechanism 9 is not reacted; regular meeting causes switch damage own, and can destroy the electrical equipment that is using, even more serious meeting breaking out of fire.

Moreover, because of electromagnet 94 is to be set in the body 92, and its periphery is covered with oil body 93, can't desire cooperate the load current value change and make an excessive trimming movement as electromagnet 94 at all, and 92 of oil seal cover 96 and bodys have the space, oil body 93 in the body 92 can constantly be leaked out, and then cause bar magnet 94 accurately to adsorb push pedal 99 in original set point, very undesirable in the use.

Other has a kind of no-fuse switch device, with reference to shown in Figure 3, it is configured to an electric copper output A, this electric copper output A one end is welded with a upright alloy sheet B, be welded with an electromagnet C on this alloy sheet B, on the other end of alloy sheet B, then be fixed with a conductive copper D, this conductive copper D one end connects a power lead E, on conductive copper D, then screwed togather a screw rod F, this screw rod F other end protrudes out and is being locked on the catch member G, this catch member G is rotatably connected on the other wall bracket H of alloy sheet B, and catch member G one end then abuts on the push rod I of brake mechanism.

This kind device is when electric current reaches critical point, alloy sheet B promptly can be crooked, and the lengthening of the magnetic line of force between lengthening electromagnet C and the catch member G, cause magnetic pull to weaken, at this moment, if powerful electric current input is arranged, promptly catch member G one end can't be adsorbed on the electromagnet C, and then cause the brake mechanism can't escape, cause user's life to cause danger and lose property.

Moreover, as electromagnet C and catch member G one end at a distance of too far then field of magnetic forece is too small, catch member G is difficult for absorption and abuts on the electromagnet C, otherwise, as electromagnet C and catch member G one end distance from too near, when then catch member G one end does not also promote push rod I, the other end promptly abuts on the electromagnet C, moreover, when catch member G is subjected to the absorption of electromagnet C magnetic force, easily fasten on the bending place of catch member G at the screw rod F on the alloy sheet B, catch member G one end can't be abutted on the electromagnet C.

In addition, because of electromagnet C is that welding manner is fixed on the alloy sheet B, therefore, when the processing electric current hour of welding, then be difficult for electromagnet C is welded on the alloy sheet B, otherwise, though can reach electromagnet C is welded on the alloy sheet B, so electric current basically destroyed the structure of alloy sheet B cause damage, caused most fragile on the whole current system a bit,, then often produced the fracture situation, and made this switch lose due function through out-of-date as big electric current.

The purpose of this utility model is to overcome the defective in the above-mentioned technology, and a kind of switch tripping device without fuse is provided, make its can want rated current overload or moment occur big electric current by the time, can in time cut off the electricity supply, guarantee the safety of the person and equipment.
