Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1 and Figure 2, a kind of backstopping device, its profile is circular, is made up of backstopping device lamination 2, and described backstopping device lamination 2 superposes in the shape of a spiral, any longitudinal cross-section of backstopping device has at least two-layer backstopping device lamination 2 superpose.Wherein, the concrete number of plies of backstopping device lamination 2, can determine according to the installation dimension of the real work occasion of backstopping device, can be three layers, four layers or more.The Thickness of individual layer backstopping device lamination 2 is 0.2-0.4mm, to ensure that backstopping device lamination 2 has good elastic performance, be conducive to extending the useful life of backstopping device and improve the impact resistance of backstopping device, but also make the installation of backstopping device, dismounting is more prone to.Dismounting conveniently after backstopping device installation, backstopping device lamination 2 is also provided with otch 5, and described otch 5 can be provided with one, and this otch 5 is arranged in any one end at backstopping device lamination 2 two ends; Described otch 5 also can be provided with two, and in the present embodiment, the otch 5 on described backstopping device lamination 2 is provided with two, lays respectively at the two ends of backstopping device lamination 2.When backstopping device entirety splits out by needs from electrical cnnector, instrument can be utilized to prize and to dial otch 5, because position, otch 5 place is narrower than other positions of backstopping device lamination 2, therefore, the end of backstopping device lamination 2 is easy to first to extract from electrical cnnector, and then take out whole backstopping device, simple to operate and easily.In addition, this backstopping device adopts stainless steel to make, because stainless steel is more durable than ordinary steel, good corrosion resistance, intensity are high, and stainless steel has the features such as excellent mouldability, compatibility and the obdurability in very wide temperature range, therefore, the backstopping device utilizing stainless steel to make is also more wear-resisting, anti-corrosion, and has more toughness, is conducive to the working life promoting backstopping device.
Backstopping device of the present invention is usually for location and the retaining of electrical cnnector insulation pad, as shown in Figure 3, Figure 4, it is the assembling end of insulation pad 3 in the rear end of electrical cnnector socket 1, socket 1 rear end endoporus there is a groove 4, when assembling insulation pad 3 in socket 1, in the groove 4 utilizing backstopping device 6 to be stuck on socket 1, to prevent the movement of insulation pad 3 simultaneously, thus play location and retaining effect.When backstopping device 6 takes out by needs from electrical cnnector, the otch 5 on backstopping device 6 is dialled by instrument sled, first the end of backstopping device 6 is separated with the groove 4 on socket 1, then can successively extracts backstopping device lamination 2, until backstopping device 6 is separated completely with socket 1.Because the superposition number of plies of the backstopping device lamination 2 of backstopping device can select different superimposed sheets numbers according to the stressed size of backstopping device, and the thickness of monolithic lamination need not be increased, therefore, backstopping device lamination 2 has better elasticity, facilitate the assembly and disassembly of backstopping device to operate, and backstopping device 6 scratch socket 1 can be avoided during operation.
For the electrical cnnector applying to EMU and multiple field of track traffic, because it has the particular/special requirements such as vibration resistance, corrosion-resistant, high security, therefore, its backstopping device used should have high strength, high rigidity, antifatigue and good corrosion resistance and formability.For meeting this requirement, the material of backstopping device used can be SUS631 (17-7PH GB 0Cr17Ni7A1), and this is a kind of precipitation-hardening stainless steel steel band, even if meet high temperature also less deformed, this kind of material is when high temperature is to 316 DEG C, and its spring performance is still good.Utilize SUS631 to make backstopping device, heat treated state is partial annealing, and the code name of material hardness is 3/4H, and meanwhile, the flexure factor of this material is about 186000N/mm
2(Newton per square millimetre), tensile strength is 1420N/mm
2above, than the flexure factor 167000N/mm of common austenitic stainless steel
2with tensile strength 930N/mm
2all much bigger, therefore many laminations and the instructions for use of backstopping device can be met well.
Many laminations of backstopping device can optimize mounting or dismounting technique, when lamination makes, indeformable when must adopt special equipment and frock to ensure lamination coiling, reverse, and also need to carry out heat treatment, to ensure size and shape requirement after coiling completes.Whole backstopping device structure is simple, and handling ease, be applied on electrical cnnector and realize reliable retaining, locating effect, and the assembly and disassembly of backstopping device is also very convenient; This kind of multi-layer stacks backstopping device is applicable to the electrical cnnector of various model, has very strong versatility and practicality.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, it should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
