Abstract
The utility model discloses a heavy-load clapping touch switch capable of avoiding contact oxidation and abrasion. The touch switch comprises a housing (1); a moving contact spring (2) is arranged inside the housing (1) and static contact springs (3) are arranged at the upper side and the lower side of the moving contact spring (2); and the spaces between the moving contact spring (2) and the static contact springs (3) are filled with switch contact lubricating oil (4). According to the utility model, when the clapping touch switch is assembled, peripheries of two sides of the moving contact springs in the switch are coated with the switch contact lubricating oil and the peripheries of the two static contact springs are also coated with the switch contact lubricating oil; and then the moderate oil is coated on two running inclined planes of a slide block, wherein the coated oil is used for realizing lubrication and reducing the friction that is caused during the running and thus an overturning speed of an overturning plate is enhanced; and finally, all prepared parts are assembled for forming a product. Therefore, phenomena of oxidation and abrasion in a severe environment with the high temperature of 150 DEG C or more that is reached by the contact can be effectively avoided.
Description
Technical field
The utility model relates to a kind of heavy duty clapper-type contact-making switch that can avoid contact oxidation and abrasion, belongs to clapper-type switchgear technical field.
Background technology
The clapper-type contact-making switch is the higher contact-making switch of a kind of frequency of utilization, and it is to promote the movable contact spring swing by slide block, and the movable contact spring of swing can contact with the static contact that is positioned at its one or both sides respectively and realize break-make.But in use find; Be not less than in the operational environment of 24V greater than 10A, operating voltage at the operating load electric current; The clapper-type contact-making switch is because product uses frequently, and the sensitive switch that adopts in the product makes its functional failure a large amount of ablations occurring in the work for a long time; With regard to its reason, mainly be product extremely in high temperature institute that high electric current produces most advanced and sophisticated electric arc of moment., it finds when being carried out testing experiment; Its clapper-type contact-making switch is under the situation of load current greater than 10A; When using 2000-15000 time between the contact a large amount of carbon distributions can appear; The high temperature that the product arcing produces can finally make functional failure with the plastic part scorification distortion of periphery, has a strong impact on the life-span and the quality of clapper-type switch.
Summary of the invention
The technical problem that the utility model will solve is: a kind of heavy duty clapper-type contact-making switch that can avoid contact oxidation and abrasion is provided, can overcomes the deficiency of prior art.
The technical scheme of the utility model is: a kind of heavy duty clapper-type contact-making switch that can avoid contact oxidation and abrasion; It comprises housing; In housing, be provided with movable contact spring, be provided with static contact, between movable contact spring and static contact, be filled with switch contact lubricating oil in the both sides up and down of movable contact spring.
Around static contact, be provided with switch contact lubricating oil.
The rated current of described heavy duty clapper-type switch is greater than 10A.
Used switch contact lubricating oil is the lubricating oil of FAKKT-V166 for the model that Germany not restrains the production of chemicals Co., Ltd.
Compare with prior art; The utility model is when assembling clapper-type contact switch; At first two peripheries of the movable contact spring in the switch are smeared full gate pass contact lubrication fat, and then two fixed contact peripheries are smeared full gate pass contact lubrication fat equally, (main rising lubricated the friction that produces when minimizing moves again an amount of grease to be coated on two operation inclined-planes of slide block; The rotating sheet reversal rate is improved), more ready each part is assembled into product.Can effectively avoid the contact point temperature to reach abrasion and oxidation under 150 degree or the higher severe rugged environment like this.In product testing with condition; The life of product of smearing switch contact lubricating grease got significantly and improved; Be that concrete experimental data does, under the condition of rated current 12A, a large amount of carbon distributions appear in the product of not smearing switch contact lubricating grease between the contact when using 2000-15000 time; Product is out of shape the plastic part scorification of periphery at the high temperature that arcing produces, and finally makes functional failure.And the product of employing contact lubrication fat, through test more than 60,000 ten thousand times, the wearing and tearing that its damage is contact chip and plastics cause between slight distortion outer contact and any ablation phenomen do not occur.Can find out that from above data the utility model prodigiosin is well avoided the abrasion and the oxidation that produce in the frequent use under the high electric current.Its effect can well be used for reference relevant similar products.
