Abstract
The invention discloses a bidirectional synchronous switch with a dumbbell-shaped metal casing and ternary eutectic liquid metal. The switch is composed of the metal casing, the ternary eutectic liquid metal, electrodes, a vacuum space in the casing and an insulated sealing body. The ternary eutectic liquid metal, which serves as a conductive medium, is added to the metal casing of the switch to replace mercury in use, the conductivity is higher, contact points of the electrodes are in liquid state contact, and there is no noise; due to high fluidity of the ternary eutectic liquid metal, arrangement of the electrode enables bidirectional synchronization, and one switch can be used to control two electric appliances which need to be switched ON/OFF simultaneously; the dumbbell-shaped metal casing can be used to reduce use of the ternary eutectic liquid metal of high price, and the appearance is beautiful; and no mercury is used in the bidirectional synchronous switch, harm of mercury to production and using staff is reduced, and environmental pollution is also reduced.
Description
Technical field
The present invention relates to the technical field of switch, espespecially dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch.
Background technology
Along with the technical merit of electron trade constantly improves, the requirement of the Performance And Reliability of switch is also more and more higher, roll-over switch in the market is adopt mercoid switch mostly, can use in severe environmental conditions although mercoid switch has, and good conductivity, cheap advantage, but there is also body once crush, can cause that hydrargyrum outflows, cause the murder by poisoning to human body and the pollution to environment, bring many inconvenience to user.
Summary of the invention
The dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch of the present invention, the deficiencies in the prior art can be solved, adopt in switch-mode metal housing, add ternary eutectic liquid metals, utilize the change make-and-break contact of ternary eutectic liquid metals liquid level, instead of poisonous hydrargyrum, it is achieved that the Non-toxic of liquid conduction switch.
The present invention dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch, the ternary eutectic liquid metals of use, its contain 62% gallium, 25% indium, 13% stannum, density is 5.91g/cm3, fusing point be 5 DEG C, electrical conductivity is 6.78 ����s 106/ (s/m).
To achieve these goals, the technical solution of the present invention is: dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switchs, and it is made up of metal shell, ternary eutectic liquid metals, electrode, vacuum space; Metal shell is also simultaneously an electrode, and another two electrode 4 is fixed on insulating seal 2 and forms electrode and shell external electrode in shell, and one end of electrode is placed in outside metal shell as junction point; Evacuation in metal shell 1, the ternary eutectic liquid metals 5 of built-in 1/3rd, concurrently forms vacuum space 3, has thus made dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch.
The invention has the beneficial effects as follows: the electric conductivity of ternary eutectic liquid metals is better, interelectrode contact resistance only small in; The contact of electrode is liquefied junction, and without any noise, ternary eutectic liquid metal flow is good, and the setting of electrode makes its bi-directional synchronization, it is achieved a switch controls two electrical equipment needing on an off simultaneously simultaneously; Dumb-bell shape metal-back can save expensive ternary eutectic liquid metals, and outward appearance is also beautiful; Dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch does not use hydrargyrum, reduces the hydrargyrum murder by poisoning to producers and user of service, reduces environmental pollution yet.

Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Accompanying drawing is a kind of dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch schematic diagram.
In figure: 1, metal shell, 2, insulating seal, 3, vacuum space, 4, electrode, 5, ternary eutectic liquid metals.
Detailed description of the invention
In order to be more fully understood that enforcement this patent, provide detailed description of the invention below in conjunction with accompanying drawing: dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch is made up of metal shell 1, ternary eutectic liquid metals 2, insulating seal 2, vacuum space 3, electrode 4, ternary eutectic liquid metals 5; Described metal shell 1 is also an electrode 4 simultaneously, and another two electrode 4 is fixed on insulating seal 2 and forms electrode and shell external electrode in shell, and one end of electrode is placed in outside metal shell as junction point; Evacuation in metal shell 1, the ternary eutectic liquid metals 5 of built-in 1/3rd, concurrently forms vacuum space 3, has thus made dumb-bell shape metal-back ternary eutectic liquid metals bi-directional synchronization switch.
The above; embodiment is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; under the premise without departing from the spirit of the technology of the present invention; various deformation that technical scheme is made by this area engineers and technicians and improvement, all should fall in the protection domain that claims of the present invention are determined.
