Abstract

The utility model relates to the field of the basic electric element used for electricity. The utility model relates to an electromechanical sealing and magnetic excitation switch. The utility model is characterized in that to one end of a housing 7 is fixedly provided with a supporting frame, and the other end is fixedly provided with a normally-closed contact 4 and a normally-opened contact 5. A movable tongue spring slice is hung in a recess on the point B of the supporting frame 6. A spring slice 3 is propped on the point C of the movable tongue spring slice 1 and the recess of the point A of the supporting frame 6. The lower side of the tongue spring slice 1 is provided with a fixing soft ferromagnetic slice 2. In the whole moving process, the utility model has the advantages of short time and high speed; under the static state, the utility model has the advantages that the contact pressure between the contacts is increased, the contact resistance is reduced, etc. Therefore, the charge capacity of the contacts is improved to nine times of the contact capacity of the existing product.

Description

A kind of Jumping spring tube

The utility model relates to the essential electronic element field of electricity, is the switch of a kind of dynamo-electric sealing, magnetic pumping.

At present, existing magnetic pumping enclosed switch---tongue tube, its major technique feature be the seal of two iron-nickel alloy tongues in a glass tube.Its operation principle is such: when external magnetic field makes the magnetization of two tongues produce the suction-combining forces greater than the recuperability of tongue self, and two tongue adhesives, contacting; After external magnetic field disappeared, two tongues were owing to recuperability is thrown off, and the contact disconnects.More than the permission maximum current of reed capsule contact of this structure be not more than 1A (250V).Therefore its electric loading is less.

The purpose of this utility model is the structure that changes the tongue tube inner contact, and a kind of Jumping spring tube that improves the novelty of contact electric charge carrying capacity is provided.

The purpose of this utility model is achieved in that

Its operation principle is to adopt the bungee contact closing, the tension force effect of the spring leaf in disconnection and the transfer process.The concrete course of work is finished like this: as shown in Figure 1, under the effect of outside magnetic field, make movable tongue 1 and fixedly soft ferromagnetic sheet 2 magnetization, produce suction, then movable tongue 1 is shifted downwards, when being lower than the A point, moving contact breaks away from normally-closed contact 4, downward and normally opened contact 5 connections by the closure state kick.When the external magnetic field disappearance, fixedly soft iron magnetic is stopped the sheet loss of excitation on soft ferromagnetic sheet 2. and the tongue, and movable tongue 1 is subjected to the tension force effect of spring leaf 3, and then to top offset, when surpassing the A point, moving contact and normally opened contact 5 are thrown off, and kick makes progress and normally-closed contact 4 connections.So just finished a course of work.

Concrete structure of the present utility model is provided by the following drawings and embodiment.

Fig. 1 is the utility model structural representation.

Each parts name is called among the figure: 1. movable tongue; 2. fixing soft ferromagnetic sheet; 3. spring leaf; 4. normally-closed contact; 5. normally opened contact; 6. support; 7. shell.

Now describe concrete structure of the present utility model with reference to the accompanying drawings in detail;

As shown in Figure 1, this Jumping spring tube is by movable tongue 1, fixedly soft ferromagnetic sheet 2, spring leaf 3, normally-closed contact 4, normally opened contact 5, support 6 and shell 7 are formed.It is characterized in that: an end fixed support 6 (being moving contact) of shell 7, the A point and the B point of support 6 are equipped with groove, and be fixing for movable tongue 1 suspension and spring leaf 3.The other end of shell 7 is normally-closed contact 4 and normally opened contact 5 fixedly, and they are up and down arranges.Movable tongue 1 is made up of thin phosphorus copper sheet that moving contact is housed and the soft ferromagnetic sheet of being close to below this sheet, in the groove that the B that leans on the tension force of spring leaf 3 to be suspended on support 6 is ordered, and can be that fulcrum moves up and down among a small circle with the B point.Spring leaf 3 withstands in the groove that the A of the C point of movable tongue 1 and support 6 orders.The below of movable tongue 1 is provided with fixedly soft ferromagnetic sheet 2, is fixed on the inwall of shell 7, with normally opened contact 5 insulation.

Advantage of the present utility model: owing to closing, all be subjected to spring leaf in disconnection and the transfer process in the bungee contact The effect of tension force, therefore, the whole motion process time that crosses the rear abrupt transitions of A point with movable tongue is short, Speed is fast, has improved the current interruption ability of contact, and makes in the indirect touch increase of static state lower contact, contact Resistance reduces, thereby has improved the electric charge carrying capacity of contact. Through sampling test, such as the appearance and size contact of Fig. 1 Capacity can reach 10A (250V), improves 9 times than the existing dry-reed contact capacity of same size.
