DIN 46247-2

德国标准 1975年3月份插头宽度为2.8的无绝缘套的插套不用于参照VDE标准的安全引线接头用于插头厚度为0.5（A）的，标称尺寸为2.8—0.5的，由CuSnF41（Bz）制成的插套的标称：插套A2.8—0.5DIN 46247－Bz母材：Ms：CuZn30F43参照DIN 17670标准Bz：CuZn6F41参照DIN 17670标准结构形式：有光泽，经过协商也可以镀锌（gal Sn3参照DIN 50965标准）或者镀银（gal Ag，镀层厚度最小为1µm），然后补充标称，例如用于镀锌的结构形式：……DIN 46247－Bz－gal Sn。

要求与检验：参照DIN 46249标准的第一分册（目前还是草案）。

适用范围：适用于终端不允许焊接的，超多股，多股，细线与极细股导线。

对于大量生产，插套可以制作成带状（Bd）形式，然后由机器卷曲到导线上，带状插套的标称为：插套A2.8－0.5 DIN 46247－Bz－Bd应用示例：用机器或者是手钳卷曲成插套。

1）其它形式的槽口凸缘必须在直径1.2mm之内。

2）底面成型由制造商根据需要进行选择。

尺寸a涉及到的底面必须是槽口凸缘超出底面（0.1±0.05）mm的底面。

3）尺寸涉及到的是以带状形式供货的插套，在单个零件的供货中这个尺寸根据制造商的选择允许存在偏差，这点取决于预成型夹头。

4）例如参照DIN 72 551第二分册的导线B，也可以把更多导线卷曲到一个插套上。

The ring is then bent through 30° by repeated light hammer blows or using a lever, following which there shall be no fractures or cracks in the ring.7.3 Testing the deformation7.3.1 Testing the conical deformationThe retaining ring is placed between two parallel plates and loaded as shown in Figure 4.

The ring shall then fit in a bore with a diameter d 2 equal to the maximum groove diameter, where it shall be held under its own weight.DIN 472:2011-10197.5 Acceptance inspectionFor acceptance inspection, the principles of testing and acceptance specified in DIN EN ISO 3269 shall apply. See Table 7 for characteristics and Table 8 for the acceptance quality level.Table 7 — CharacteristicsTable 8 — Acceptable quality level AQLIf other sampling plans are to be applied, this shall be agreed at the time of ordering. For hardness testing, DIN EN ISO 3269 shall apply.The hardness test of retaining rings shall be regarded as a destructive test.8 Load bearing capacity8.1 GeneralDimensioning of a retaining ring assembly requires separate calculations for the load bearing capacity of the groove F N and for the load bearing capacity of the retaining ring F R . In each case the resulting lower value is decisive. The load bearing capacities listed in Tables 1 and 2 (F N , F R , F Rg ) contain no safety factor against yield under static loading or against fatigue fracture under dynamic loading. There is at least twice the level of safety against fracture under static loading.8.2 Load bearing capacity of groove F NThe values of F N given in Tables 1 and 2 apply for a yield point of the material in the region of the bore groove of R eL = 200 MPa as well as for the given nominal groove depths t and edge margins n .The load bearing capacity F'N for deviating groove depths t ' and yield points R 'eL shall be calculated using Equation (1):200'''eLN N R t t F F ⋅⋅= (1)DIN 472:2011-10208.3 Load bearing capacity of retaining ring F RThe values of F R given in Tables 1 and 2 apply for an assembly over the maximum diameter 1,01 × d 1 (seeClause 10) and for a sharp-edged abutment of the machine component (see Figure 6).Key 1Retaining ringKey 1Retaining ringFigure 6 — Sharp-egded abutmentFigure 7 — Abutment with edge chamferingdistance (chamfering or rounding)The values of F Rg apply to an abutment with an edge chamfering distance g (see Figure 7). The values of F R and F Rg apply to ring materials with a modulus of elasticity of 210 000 MPa.If the existing edge chamfering distance g ' deviates from the values specified in Tables 1 and 2, then, for conversion, the load bearing capacity of the retaining ring is indirectly proportional to the edge chamfering distance:''Rg Rg g g F F ⋅= (2)NOTEIf F 'Rg with smaller values of g ' is greater than F R , then F R applies.If the existing forces cannot be accommodated because the edge chamfering distance is too great, then asharp-edged abutment is to be made by means of a supporting ring complying with DIN 988 (see Figure 8).Key 1 Retaining ring 2Supporting ringFigure 8 — Sharp-edged abutment at the retaining ring using a supporting ringDIN 472:2011-10219 Design of the groove9.1 Groove diameter d 2The groove diameters d 2 specified in Tables 1 and 2 are selected so that the retaining rings are seated in the groove with prestress.NOTE Greater groove diameters are possible if prestress can be dispensed with. The upper limit is: d 2max = d 3min .9.2 Groove width mAs a rule, tolerance zone H13 applies for the groove widths specified in Tables 1 and 2. With unilateral force transmission, the grooves can be widened and/or chamfered towards the relieving side. The groove width has no influence on the load bearing capacity of the retaining ring joint. Companies can therefore specify their own groove shapes and widths.If the retaining ring is to alternately transmit the forces onto the groove walls in both directions, the groove width m shall as far as possible be matched to the ring thickness s , e.g. by also reducing the tolerance. SeeFigures 9a) to 9d) for groove shapes.a)b)c)d) Figure 9 — Groove shapesDIN 472:2011-10229.3 Design of the groove baseThe rectangular groove is the standard form (see Figure 9a)). The radius r on the loaded side shall not exceed 0,1 × s . Other suitable groove shapes are shown in Figures 9b) to 9d). In the case of a sharp-edged rectangular groove, the notch sensitivity of the material used produces a corresponding notch effect factor.Details of the groove base design are shown in Figure 10.Key1 Point for measuring perpendicularity 2Possible contours a Tolerance zone Figure 10 — Design of groove baseDIN 472:2011-1023 10 AssemblyRetaining rings shall be assembled by means of pliers conforming to DIN 5256 or using tapers.During assembly care shall be taken to ensure that the ring is contracted only to the extent necessary for insertion into the bore, i.e. to a diameter not smaller than 0,99 × d 1. If necessary, pliers equipped with limiting screws (set screw) shall be used. The most reliable protection against overexpansion is assembly using a taper (see Figure 11). Where an additional sleeve is to be provided, e.g. to install rings with a larger edge margin n or to protect the bore surface during assembly, it is recommended that the manufacturer beconsulted.a)b) c)Key1 Pressure pin2 Retaining ring3 Taper4 Groove5 HousingFigure 11 — Taper assembly 11 DesignationEXAMPLE 1 Designation of a retaining ring for a bore diameter (nominal size) d 1 = 40 mm and with a thicknesss = 1,75 mm: Retaining ring DIN 472 — 40 × 1,75EXAMPLE 2 If, by way of departure from Table 4 rings with a specific corrosion protection are required, this shall be indicated in the designation by adding the relevant symbol.

出口商品技术指南微波炉中华人民共和国商务部2021年11月前言2020年新冠肺炎疫情来袭，在疫情的影响之下，全球经济由疲软转向衰退的风险明显上升，供给侧和需求侧同时面临萎缩，贸易陷于停滞状态，加上地缘政治冲突升级、全球贸易摩擦不确定性风险犹存等因素，中国家用电器行业出口受到了一定冲击。

然而，“少聚会、少聚餐”的倡议让全球人们与吃有关的生活习惯发生了巨大的变化。

对于与人们生活紧密相关的厨房电器——微波炉而言，新冠肺炎疫情给之带来一波新的出口行情，自2020年起出口额逆势上扬，大幅增长。

据海关总署统计数据显示，2020年中国微波炉出口量为6741.28万台，较2019年增加了760.84万台。

2020年中国微波炉出口金额为323722.50万美元，较2019年增加了33574.74 万美元。

近年来国际经济贸易形势不断发生着复杂而深刻的变化。

虽然受到国际金融危机以及全球经济增速放缓等因素影响，我国家电产品的出口额总体上还是处于上升趋势。

中国是全球微波炉需求量的出口大国，在新的国际市场环境及经济贸易形势下，为了便于出口家电企业更充分地了解国际上各种技术性贸易措施产生背景和表现形式，以及有关家电产品标准的变化情况，在商务部发布的《出口商品技术指南——微波炉》（2014年版）的基础上，中国家用电器研究院再次受商务部委托，根据2014年以后出口家电市场面临的各种新的技术性贸易措施以及主要出口国家和地区产品技术标准的演变情况，进行了修订。

本次修订涉及的内容包括：1）对近十年出口微波炉市场的情况和数据进行了系统汇总统计，同时对各大洲以及重点国家的出口情况进行了分析说明；2）更新了我国微波炉安全标准与最新版IEC标准的技术差异比对和解读；3）更新了我国微波炉性能测试方法标准与最新版IEC标准的技术差异比对和解读；4）更新了我国安全标准与日本安全标准的技术差异的比对和解读，并对2014年实施的全新修订的日本电气用品安全法进行了分析说明；5）增加了我国安全标准与美国标准的技术差异的比对和解读；6）更新了欧盟RoHS指令对于家用电器产品中有害物质的豁免清单；7）增加了对一带一路沿线国家和地区技术壁垒近期对策的思考；8）增加了最新版IEC标准的译文：IEC 60335-2-25:2020家用和类似用途电器的安全微波炉，包括组合型微波炉的特殊要求；9）更新了我国微波炉性能测试方法标准的内容：GB/T 18800-2017 家用微波炉性能试验方法。
