Description

The electric children vehicle Protection switch

[technical field]

The utility model relates to a kind of electric children vehicle switch, is a kind of electric children vehicle Protection switch specifically.This switch is to design at enter problems such as the fault that causes in the switching device or loose contact because of water and dust.

[background technology]

What the electric children vehicle industry was selected for use at present is the instrument and meter waved switch that only has general utility functions, and the common environment for use of the switch of this function is indoor, and degree of protection is IP20 (promptly the protection finger does not require water proof and dust proof near dangerous parts).And electric children vehicle uses under the outdoor environment through being everlasting, in a single day dust or water enter in the switching device can cause fault or loose contact, and the load characteristic that electric children vehicle uses is low-voltage (6V, 12V) big electric current (30A), require higher to the switch contact performance: under low-voltage state, switch contact resistance is big, shows as not conducting, the perambulator afunction; Under current state, often cause the heating of switches conductive body, make molten soft distortion of plastic substrate and contact point silver layer accelerated cure rotten, thereby cause the bigger vicious circle of contact resistance, final switch failure, perambulator afunction.To switch the rate of complaints, product quality shows very big regional difference from the client of perambulator industry, and region the rate of complaints that dust storm is big is obviously higher.To the disable switch analysis, 95% defective products is that contact resistance that the contact contact surface causes because of dust pollution exceeds standard and causes.Therefore, require electric children vehicle can adapt to different environment,, keep the clean conditions of switches conductive body, prolong perambulator useful life especially at the big regional outdoor environment of dust storm dust with switch.The utility model provides a kind of switch that the electric children vehicle industry is used that adapts to, and can play the waterproof and dustproof effect fully, guarantees that contact and conductive pieces are in air-tight state, prevent contact and conductor silver layer sulfureted phenomenon in air.Protection switch is if the correct cabinet that cooperates uses, and its degree of protection reaches IP66.

[summary of the invention]

Can not adapt to the problem that the electric children vehicle industry is used for solving existing switch degree of protection, the utility model adopts switching manipulation part and the airtight isolation in the electric chamber of switch, accomplishes that simultaneously the electric chamber of switch directly is not communicated with outside.Like this, prevent that dust or water from entering the electric chamber of switch from the switching manipulation position, make electric chamber integral body be in closed state simultaneously, effectively protect electric conductor in the electric chamber, contact silver layer surface not to be subjected to the influence of sulfide in the air.

The technical scheme that its technical problem that solves the utility model adopts: 1, for saying something, switch is divided into three parts in upper, middle and lower, its top comprises parts such as operating parts 1, dust cover 3, compacting ring 2, and dust cover 3 is flexible part made from silicon rubber or nitrile rubber or PVC; The middle part comprises parts such as shell 4, driving member 5, spring 6, steel ball 7, and an end of dust cover 3 is connected with the shell interlayer, and the other end is connected with operating parts, driving member, and two ends are all compacted.Shell 4 is topmost parts in the switching device, and its inside has a horizontal interlayer that switching manipulation part and electric part are separated, and there is a circular hole at the interlayer center, is used for operating parts and steps down with being connected of driving member.There is an annular groove in the circular hole outside, is used for placing and compressing dust cover, on the two long sidewalls below the interlayer two inverted U-channels is arranged respectively, is used for placing and locating driving member, and two square holes are respectively arranged at the bottom of two long sidewalls, are used to tangle the hook on the pedestal; The bottom comprises touches bridge 8, middle connecting terminal 10, edge joint line terminals 11, pedestal 12, and pedestal is provided with convex edge, four limits.2, switch top and middle part is connected.Earlier cannelure on shell 4 interlayers is put in dust cover 3 lower edges, ring slot outside has an annular groove, there is annular convex rib in compacting ring 2 outsides, compacting ring is pressed into and closely cooperates with the groove side in the groove and the dust cover lower edge is compressed, prevent that compacting ring from deviating from, then driving member 5 mider holes up two side shafts put into side wall of outer shell two U-lags.At last, one oblate mast is arranged on the operating parts, one hanging platform is arranged at oblate mast bottom, corresponding positions is equipped with a hook on the driving member, it is interlockable that both connect the back, oblate mast below the operating parts 1 is passed in dust cover 3 upper edge mesopores and driving member 5 mider holes successively, make driving member 5 be connected interlocking with operating parts 1, dust cover 3 upper edges are pressed between operating parts 1 and driving member 5 composition surfaces.Like this, the operation part of switch and electric part are by shell interlayer and the airtight isolation of dust cover, and water or dust can not enter the electric chamber of switch from the operating position.3, switch middle part and bottom is connected.Touch bridge 8 and constitute with contact 9 riveted joints and touch the bridge parts, edge joint line terminals 11 constitutes the edge joint line terminal portions with contact 9 riveted joints, and edge joint line terminal portion and middle connecting terminal 10 insert to be split riveting in pedestals 12 square holes and connect and compose base component; In two circular holes of driving member 5 bottoms, put into the spring 6 that two is stained with vaseline, the spring exposed junction is stained with steel ball 7, put at middle connecting terminal 10 end faces of base component and to touch the bridge parts, base component is pushed in the big square hole of outer casing bottom together with touching the bridge parts, make the hook on the base component be connected sealing with four hooks of shell side.Like this in shell interlayer four sidewalls, just form the electric chamber of switch of a sealing on the pedestal more than the plane, contact and conductive pieces are hedged off from the outer world in the electric chamber of this switch fully, thereby reach dustproof, waterproof effect.

The beneficial effects of the utility model are, are connected with dust cover by shell interlayer and dust cover and operating parts, driving member, and with the airtight isolation of electric chamber of switch and operating parts, the intrusion of effectively anti-sealing and dust is to the influence of switch electric function; The processing that processing that is connected with shell by driving member and base plate are connected with shell, electric chamber of switch and external environment condition are isolated, effectively sulfiding gas guarantees that to the erosion of switch conductor and contact silver layer electric children vehicle can not cause the whole functional disappearance because of switch problem in the protection air.
