Description

A kind of beam type overload connects electric switch

Technical field

The utility model belongs to switching technique field, and in particular to a kind of beam type overload connects electric switch.

Background technology

Inertia switch be using carrier percussion target when reaction force or preshoot inertia force and close, realize circuit by It is disconnected to the function of connection.Inertia switch has extensive demand in electro-mechanical arts and automotive field.Existing inertia switch master If by big sleeve 7, catch 8, intermediate insurance spring 9, contact sub-sleeve 10, inertia contact shoe 11, small sleeve 12, lower contact 13, Lower contact extraction wire 14 is constituted, and concrete structure is shown in Figure of description 3.Not only version is complicated for existing inertia switch, and And catch is formed with the riveting of inertia contact shoe, total is fixed using Type of Welding, and part exchanging is inconvenient.

Utility model content

For the disadvantages described above or Improvement requirement of prior art, the utility model provides a kind of beam type overload and connects electricity Switch, with simple structure, can Reusability, contact reliability and the characteristics of long closing time.

A kind of beam type overload connects electric switch, including metal cantilever beams, electrode, permanent magnet, housing and cap；Metal hangs One end of arm beam is fixed on the side wall of housing, and the other end is hanging；Two electrodes are fixed on the bottom of housing, be spaced from each other and Two electrode bases respectively draw a wire；Permanent magnet is placed in the middle of two electrodes；Cap is installed on the open top of housing, Whole mechanism is closed into into an entirety.

Further, the free end of the metal cantilever beams is trapezium structure.

Further, the material of the metal cantilever beams be iron, any one in cobalt, nickel.

Further, one end of the electrode is elongated cantilever structure, and for beryllium-bronze material.

Further, the housing and cap are nonmetallic materials.

Advantageous Effects of the present utility model are embodied in：

At ordinary times, two electrodes are spaced from each other as the two poles of the earth of switch, and switch is off.When metal cantilever beams sense When being transshipped by pointing to two electrode directions, metal cantilever beams overcome drag itself to move along overload direction, until with two Individual electrode contact, now, switchs from disconnection and is changed into conducting.The utility model have simple structure, can Reusability, contact it is reliable And closing time it is long the characteristics of

Further, the metal cantilever beams that nickel material makes are contacted with permanent magnet, and the magnetic force that permanent magnet is produced ensures reliable Adsorbing metal cantilever beam, extends the time of metal cantilever beams and two electrode contacts.

Further, two electrode one end are elongated cantilever structure, and to deform preferable beryllium-bronze material, it is ensured that Metal cantilever beams are contacted simultaneously with two electrodes, and above-mentioned measure ensure that the moment of metal cantilever beams and two electrode contacts not Can flick, improve the contact reliability of switch.

Description of the drawings

Fig. 2 is that beam type overload connects structural representation when electric switch is turned on；

Fig. 3 is the structural representation of existing certain inertia switch；

Wherein, metal cantilever beams 1, electrode 2, permanent magnet 3, housing 4, the wire of cap 5,6, big sleeve 7, catch 8, centre is protected Dangerous spring 9, contacts sub-sleeve 10, inertia contact shoe 11, small sleeve 12, lower contact 13, lower contact extraction wire 14.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and specifically Embodiment, is described in further detail to the utility model.It should be appreciated that specific embodiment described herein is only to solve The utility model is released, is not used to limit the utility model.Additionally, in the utility model disclosed below each embodiment As long as involved technical characteristic does not constitute each other conflict and just can be mutually combined.

A kind of beam type overload connects electric switch, including metal cantilever beams 1, electrode 2, permanent magnet 3, housing 4 and cap 5. One end of metal cantilever beams 1 is fixed on the side wall of housing 4, and the other end is hanging, and two electrodes 2 are fixed on the bottom of housing 4, phase Mutually separate and a wire 6 is respectively drawn in two bottoms of electrode 2, permanent magnet 3 is placed in the middle of two electrodes 2, is also secured at shell The bottom of body 4.Cap 5 is installed on the open top of housing 4, and whole mechanism is closed into into an entirety.

At ordinary times, two electrodes 2 are spaced from each other as the two poles of the earth of switch, and switch is off.When metal cantilever beams 1 When experiencing the overload in two electrode (2) directions of sensing, metal cantilever beams 1 overcome the drag of itself to move along overload direction, directly To contacting with two electrodes 2, now, switch from disconnection and be changed into conducting.

The free end of the metal cantilever beams 1 is trapezium structure, can be abutted against with two electrodes 2 simultaneously when deforming in place Touch, it can be the magnetic materials such as iron, cobalt, nickel that the material of metal cantilever beams 1 is.The metal cantilever beams 1 that nickel material makes and permanent magnet 3 Contact, the magnetic force that permanent magnet 3 is produced ensures reliable adsorbing metal cantilever beam 1, extends metal cantilever beams 1 and connects with two electrodes 2 The tactile time.

Two one end of electrode 2 are elongated cantilever structure, and to deform preferable beryllium-bronze material, it is ensured that metal hangs Arm beam 1 is contacted simultaneously with two electrodes 2, and above-mentioned measure ensure that the moment that metal cantilever beams 1 are contacted with two electrodes 2 will not bullet Open, improve the contact reliability of switch.

The housing 4 and cap 5 are nonmetallic materials.

The above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
