Description
Technical field
The present invention relates to a kind of sealing configuration, relate in particular to the sealing configuration of a kind of railway with sealed case.
Background technique
At present, China railways is laid with the casing that telecommunication cable, signalling arrangement are equipped with in a large amount of inside along the line, as signal cable box, signal transformer chamber etc., commands and guide the normal operation of train.Because casing generally all places in the open, be exposed to and expose to the sun and rain, even in the severse weathers such as sand and dust, dust storm, be sealed case so require casing, and have certain security level, enter the electric leakage that causes or peril such as creepage to prevent rain leakage, sand and dust.The railway of prior art is generally IP5X or lower security level with the security level of sealed case at present, the security level of these sealed cases still is not high enough, having grown the insulation class that can cause sealed case service time reduces, cause electric leakage or creepage phenomenon, serious also may cause telecommunication cable, signalling arrangement explode.
Summary of the invention
Technical problem to be solved by this invention is at above the deficiencies in the prior art, and the sealing configuration of a kind of good sealing effect, sealed case that insulation class is high is provided.
For addressing the above problem, the invention provides a kind of sealing configuration of sealed case, comprise the receiving groove, the cyclic spring Sealing that is placed in receiving groove that are positioned at the casing upper edge, be located at the plate that supports that being used on the case lid compresses elastomer seal, the surface of contact that supports plate and elastomer seal is a plane, elastomer seal with support plate and push against mutually by the hold down gag of being located on casing and the case lid.
The hardness of described elastomer seal is 45～50 °, and the decrement of elastomer seal is 1～1.5mm, and the surface planarity that supports plate is not more than 0.4.
After adopting above structure, the present invention compared with prior art, have the following advantages: its elastomer seal of the sealing configuration of sealing case with support plate and push against the external stability of carrying out the mutual alignment mutually by the hold down gag of being located on casing and the case lid, make elastomer seal and support that plate closing is intact, tightness is suitable, the surface of contact that supports plate and elastomer seal is a plane, the decrement of elastomer seal is at 1～1.5mm, and such decrement makes seal degree height between elastomer seal and the plane that contacts with it; The hardness of elastomer seal is 45～50 °, this make this elastomer seal good springiness, be difficult for aging, water proofing property is strong; The surface planarity that supports plate is not more than 0.4, and this makes that support each position of plate is consistent uniformity height substantially to the decrement of elastomer seal.Comprehensive above these factors find that through on probation and test the security level of the sealing configuration of sealing case reaches IP67, good sealing effect, and the insulation class height can effectively prevent problems such as rain leakage, sand and dust enter, thereby has effectively avoided the generation of peril.
The cross section of described receiving groove is semicircle.Semicircular structure can realize better that the decrement of elastomer seal is the requirement of 1～1.5mm.
As preferably, the material of described elastomer seal is an Ethylene Propylene Terpolymer.The Ethylene Propylene Terpolymer good springiness, be difficult for aging, water proofing property is strong, applicable to 40 ℃～80 ℃ not hardening, aging, working life is more than 10 years.
As preferably, described elastomer seal with support plate and push against mutually by hinge means and the locker that is positioned at casing and case lid offside.The combination folding with convenience of hinge means and locker and rotating flexibly can effectively be controlled elastomer seal and support tightness between the plate, thereby meets the requirements of the decrement of elastomer seal.
As further preferred, described locker comprises lock body and lock pin, lock body is provided with and is used to the main lockhole that allows lock pin be inserted through, lock body one side is embedded with a metalwork, the sidewall of metalwork place side is provided with the secondary lockhole that connects with main lockhole, and secondary lockhole passes metalwork and is provided with internal thread, is combined with fastening screw trip bolt in the secondary lockhole, lock pin is that the lower end is provided with externally threaded metal barred body, and is provided with the fastening nut from main lockhole bottom lock pin is tightened up that screws with outside thread.This locker is provided with main lockhole and secondary lockhole, forms double locking, can realize the control of making elastomer seal and supporting tightness between the plate when having high theftproof performance effectively, and the decrement that makes elastomer seal is within claimed range.
