Description

Tilt switch

The utility model is relevant a kind of tilt switch, especially refer to a kind of easy and free of contamination tilt switch, mainly be to establish the tool accommodation space in a braking parts, an and ccontaining within it magnetic element, and combine with a triggering portion in an end of this braking parts, and triggering portion inboard be provided with can be subjected to above-mentioned magnetic element near and the two elasticity electric contact points that touch of induction, and then when the orientation of global switch produces the variation of inclination off normal, can force this magnetic element to produce displacement, contact or separate with the above-mentioned elasticity electric contact point of magnetic force priming, the contact of contact is whether as the operation of circuit between conducting two contacts.

Tilt switch is widely used at present a kind of sensing type switch, general common anti-theft alarm trigger switch that is used for vapour, locomotive or electrical equipment are used anti-ly topples over safe trigger switch, then many in form based on mercoid switch (as shown in Figure 1 and Figure 2), ball contact-making switch and spring vibration switch, the former utilizes the mercury 71 in the mercoid switch 70 to tilt, move to touch and preset

electric contact

72,73 with article, the conducting of sending a telegraph the road whether, to trigger alarm; The ball contact-making switch is to contact two electrode points generation effects with metal balls in displacement in addition, and spring vibration then is to utilize prominent shaking to cause that spring triggers with different limits, and produces alarm; Yet, though above-mentioned mercoid switch is because of having preferable sensitivity, and widely need to adopt, because of mercury itself contains severe toxicity than the electrical equipment of sensitive trigger, and the container domestic demand of loading mercury pours into hydrogen to eliminate the danger that arc discharge was caused, thereby it makes place suitable safety measure must be arranged, and, because the recovery problem of mercury is serious, can't meet environmental protection requirement, forbidden by countries in the world gradually, and its cost costliness, also value-for-money not; The ball contact-making switch then produces error and loose contact because of its contact is normal, also easy thereby generation spark damage electric contact is unsatisfactory; Another kind of spring vibration switch is then for gentle effectively perception of unusual fluctuation, so, how can develop one separately and conform with above-mentioned requirements and function trigger switch, be the direction of present relative effort.

The utility model promptly aim to provide a kind of simple in structure, with low cost, effect is sharp, meet the tilt switch of environmental protection.

The purpose of this utility model is achieved in that the utility model mainly is made up of institutes such as braking parts and triggering portions.It is with the ccontaining magnetic element of the braking parts of a tool accommodation space, and can utilize this magnetic element in braking parts, to move closer to one and respond at least one group of elasticity electric contact point that touches, when this magnetic element is moved near elasticity electric contact point place, then can be by the magnetic field that this magnetic element produced, force this group elasticity electric contact point to produce induction and touch and turning circuit, to form a simple structure, with low cost, the sharp excellence of effect and to meet the tilt switch of environmental protection.

As for detailed construction of the present utility model, application principle, effect and effect, then the explanation of doing with reference to following adjoint can be understood completely:

Fig. 1 is the schematic diagram of general traditional mercoid switch;

Fig. 2 is the schematic diagram of another traditional mercoid switch;

Fig. 3 is the schematic diagram of the utility model possible embodiments;

Fig. 4 is the schematic diagram of another possible embodiments of the utility model;

Fig. 5 is the utility model schematic diagram of a possible embodiments again.

With reference to accompanying drawing, in conjunction with the embodiments, the utility model is described in further detail.

Please join shown in Figure 3, the utility model tilt switch is the braking parts 1 by accommodation space 21 in the tool, a ccontaining magnetic element 2 in accommodation space 21, and be provided with a triggering portion 3 at an end place of this braking parts 1, this magnetic element 2 is to be combined into a magnetic material that is divided into positive reversed polarity according to the radial portion of above-mentioned accommodation space 21, the inboard of triggering portion 3 then has the two at least two elasticity electric contact points 31 that are normally open, so when this braking parts 1 produces to tilt to move, and when sliding onto near triggering portion 3 places, then can be by these magnetic element 2 magnetic field effects that produced own, can make elasticity electric contact points 31 in the triggering portion 3 be subjected to its magnetic field induction and attract mutually to touch and finish the function of turning circuit: when magnetic element 2 produces rightabout inclination once more, can return to initial state according to itself weight, 31 of elastic contact blades again can because of magnetic field or relevant magnetic force disappears and replied to separating not contacted off state by the elastic force of itself; So, tilt switch of the present utility model can produce the function of interrupted keying circuit owing to the influence of external tilt variation, and the sensitivity that its tool is high, more the problem of environmental pollution that can avoid existing mercoid switch to produce is the tilt switch design that more has practical value.

Please join shown in Figure 4, tilt switch of the present utility model can be reached identical effect by another set-up mode, be about to the guide rail 5 that braking parts 1 is to set up on the substrate 4 non-magnet_conductible material instead, then wear a magnetic element 2 (being illustrated as a bead-like body) on this guide rail 5,3 in triggering portion is incorporated into an end of this guide rail 5, this magnetic element 2 maintains on the guide rail 5 with the slip state of balance, and when magnetic element 2 slides onto adosculation and sends out portion 3, the elasticity electric contact point in it 31 is produced the induction trigger actions.

Please join shown in Figure 5 again, hold above-mentioned shown in Figure 3, tilt switch of the present utility model is to apply to multidirectional inclination open circuit mode, it is with support seat 6 ccontaining magnetic elements 2 of the multi-direction accommodation space of a tool, and be arranged to the body of multi-direction passage 61 in this support seat 6, and with the corresponding respectively ends that are incorporated into the passage 61 of this support seat 6 of some triggerings portion 3, and when the restricted and inclination and offset of this magnetic element 2 during to the inner end of arbitrary passage 61, then the magnetic field effect that can be produced by magnetic element 2 makes the triggering portion 3 of this side produce the induction turning circuits; Otherwise, when magnetic element 2 away from, then disconnect this circuit, the switch of this kind kenel is common to and makes the triggering portion 3 that magnetic element 2 all can the conducting all directions when the non-directional slippage, the deficiency of replenishing the unidirectional type application function.
