This standard (EN 16602-70-18:2014) originates from ECSS-Q-ST-70-18C. This European Standard shall be given the st

    28、atus of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2015, and conflicting national standards shall be withdrawn at the latest by April 2015. Attention is drawn to the possibility that some of the elements of this document may be the subje

    29、ct of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document has been developed to cover specifically

    30、 space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standar

DIN EN 16602-70-18:2015-02 EN 16602-70-18:2014 (E) 6 Introduction The main part of this Standard is based on industrial experience and recommendations from European soldering technology experts. Modifications are incorporated into the text to pro

    33、vide for the specific requirement of low-outgassing electrical systems which are required by scientific and application satellites. Other additions were made in the light of recent technological advances and results of metallurgical test programmes. The use of processes other than solder assembly is

    34、 recognized, but only certain general requirements are given in this Standard. These requirements apply to assemblies designed to operate within the temperature limits from -45 C to +85 C. More extreme temperatures or other unusual environmental applications require special design measures or proces

    35、sing steps to provide environmental survival capability. DIN EN 16602-70-18:2015-02 EN 16602-70-18:2014 (E) 7 1 Scope This Standard defines the technical requirements and quality assurance provisions for the assembly and mounting of high-reliability, radio-frequency (RF) coaxial-cable interconnectio

    36、ns for use as transmission lines in spacecraft and associated equipment. In general, these assemblies are designed for low-loss, stable operation from the relatively low frequencies through the higher frequencies in the microwave regions. These transmission-line cables should not be confused with lo

    37、w-frequency cables with conductive sheaths (usually copper braid), which are used in applications where shielding of the centre conductors from the surrounding electrical ambient is required. The interconnection of those shielded cables, not covered by the present standard, is covered in ECSS-Q-ST-7

    38、0-08. This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.

    46、quisites of reliable soldered or crimped cable connections 4.1 Principles of reliable soldered or crimped semi-rigid cable connections Reliable soldered or crimped connections result from proper design, control of tools, materials and work environments and careful workmanship. The basic design conce

    47、pts, adherence to which ensures reliable connections and prevents joint failure, are: a. Avoidance of dimensional mismatch between the coaxial-cable assembly and the units being connected; i.e. not forcing the semi-rigid cable assembly into position and thereby cracking or pre-stressing one of the j

    48、oints. b. Use of cable-end connectors with retractable (non-captive) coupling nuts; after completion of mounting, the coaxial-cable assembly is not in a state of tension resulting from axial movement when the connectors are threaded together. c. Minimizing the internal stresses on the soldered or cr

    49、imped connections resulting from exposure to thermal cycling. NOTE The thermal coefficient of expansion of the dielectric is about ten (10) times that of copper and in service this can introduce a tensile stress on the joint. d. The various assembly and mounting processes are covered by quality-control inspection steps. 4.2 Prerequisites for assembly and mounting of semi-rigid coaxial cables Each supplier maintains documented soldering or crimping programmes which meet the requirements of this Standard for the types of conne
