Description
Technical field
The utility model relates to a kind of magnetic switch, can be used in the vacuum-assisted switch or the occasion of other magnet proximity switch.
Background technology
Power industry vacuum-assisted switch internal switch contact commonly used develops into present tongue tube by mechanical friction type.Tongue tube has many advantages, and is little as volume, good leak tightness, and contact is not subjected to environmental pollution etc.But also there is self deficiency in tongue tube, and the current switching ability is lower, and is withstand voltage lower, the easy fragmentation of body etc.Especially make-break capacity can't satisfy the requirement of big current switching.Such as, exchanging 10 amperes, tongue tube is not accomplished at all.Tongue tube is used in these electrical circuits that may overload at present, and is abnormally dangerous, causes phenomenons such as the tongue tube puncture burns out easily, has a strong impact on user's use, even brings graver results to power transmission and transformation system.
Application number " 201020131519.0 ", name is called the Chinese utility application of " a kind of magnetic switch ", has related to a kind of magnetic switch that utilizes the auxiliary break-make of magnet steel, is used in the vacuum-assisted switch or the occasion of other magnet proximity switch.Because the contact of this design is a normally opened contact, and needs the attraction of magnet steel to come closing contact, make circuit form path, exist to be not suitable for the user demand of normally closed loop.
Summary of the invention
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of magnetic switch is provided, and can be used for the instructions for use in normally closed loop, the occasion of the big electric current of break-make, the security performance of raising circuit.
The utility model is to be achieved through the following technical solutions:
A kind of magnetic switch includes shell, is arranged in the switch element and the pair of electrodes of shell inner cavity; Wherein, described shell inner cavity is a closed chamber; Described switch element includes angle worm point closed mutually under a pair of nature, and one of them is a moving contact at least in a pair of described contact; A pair of described contact is connected separately with pair of electrodes respectively; On electrode that described moving contact is connected, be provided with magnetic devices.
To sum up, the beneficial effects of the utility model are:
The utility model provides a kind of magnetic switch, and one of them is a moving contact at least owing to a pair of described contact; A pair of described contact is connected separately with pair of electrodes respectively; On electrode that described moving contact is connected, be provided with magnetic devices.Can be used for vacuum-assisted switch inside with the alternative dry reed pipe, also can be used for other magnet proximity switch occasion.When external magnetic devices during near magnetic switch, externally rapidly two contacts to be drawn back under the pulling force of magnet steel, disjunction is strong and fast, is unlikely to inseparable because of arcing when making the big electric current of disjunction, thereby has improved the breaking capacity of switch effectively.When external magnetic devices was left magnetic switch, the contact was closed under elastic reaction, and the active force that arcing produces has positive role to the closing of contact, thereby also will soon arc extinguishing.Described shell inner cavity is a closed chamber, has improved resistance to impact, does not resemble the tongue tube easy to be crackedly, has effectively protected contact endurance, has also played the arc extinguishing effect simultaneously, thereby has also improved production efficiency.Magnetic devices can strengthen the distance of separation of contact and separate speed, can effectively improve the withstand voltage of product and breaking current ability.

Embodiment:
As shown in Figure 1, 2, present embodiment discloses a kind of magnetic switch, comprises pair of contact, i.e. moving contact 3 and fixed contact 4, and the surface of described moving contact 3 and fixed contact 4 includes conducting metal.
Described shell includes: the body 8 of a cuboid, be positioned at the plug 7 at body both ends open place and be positioned at the casting glue 6 in plug 7 outsides.
A pair of described electrode, i.e. first electrode and second electrode; Described moving contact 3 is fixed on the shell fragment 1, and described shell fragment 1 is the elastomer that an elongated sheet is conducted electricity, and moving contact 3 is fixed on the inner end of shell fragment 1, and the outside that shell is stretched out in the outer end of shell fragment 1 forms first electrode.
Described magnetic devices is powerful magnet steel 2, is arranged in shell inner cavity, and is fixed on the shell fragment 1.
Described shell fragment 1 adopts the polyline shaped structure; Be that described shell fragment 1 includes straightway and tilting section, first electrode is the outer end of shell fragment 1 straightway; Powerful magnet steel 2 is fixed on the medium position of shell fragment 1 tilting section, and moving contact 3 is fixed on the inner end position of shell fragment 1 tilting section.
Moving contact 3 and powerful magnet steel 2 all adopt riveted way and shell fragment 1 to be fastenedly connected.
Fixed contact 4 is riveted on the stator 5, and the contact-making surface of fixed contact 4 and moving contact 3 is provided with in opposite directions, and the outside that shell is stretched out in the outer end of stator 5 forms second electrode.
