5、 AS81714A Terminal Junction System (TJS), Environment Resistant General Specification For FSC 5940 RATIONALE Limited Scope revision required to address AS81714-A1 contact resistance limits for wire size 28 in Table 2. 1. SCOPE This specification covers Terminal Junction System (TJS) components which
6、 are used for interconnection of wiring and incorporation of passive components (see 6.1). These environment resistant components have in common the use of crimp type external pin contacts in accordance with AS39029/1 for Series I or crimp type external socket contacts in accordance with AS39029/22
7、for Series II. This family of TJS components is designed to operate continuously over a temperature range of -65 to 200 C, using any combination of temperatures generated by the electrical load and ambient temperature so that the maximum internal hot spot, combined temperature, will not exceed the m
8、aximum specified for the class of TJS component, unless otherwise specified (1.2, 3.1). The components making up the system and covered by this specification include: a. Terminal junction bussing blocks (6.8.2) (1) Feedback type (6.8.2.1) (2) Feedthrough type (6.8.2.2) b. Racks (mounting holders) fo
9、r blocks (6.8.3) c. Brackets, block mounting (6.8.4) d. Wire in-line junctions (6.8.5) e. Grounding terminal (6.8.6) f. Grounding blocks (6.8.7) g. Electronic blocks (6.8.8) h. Electronic in-line junctions (6.8.9) SAE INTERNATIONAL AS81714B Page 2 of 47 1.1.1 CTS The TJS components conform to the re
10、quirements of MIL-HDBK-1277 and MIL-HDBK-454. 1.2 Classification 1.2.1 Terminal junction components fabricated to this specification are classified as follows: a. Series. The Series I and II TJS components are not interchangeable or intermateable. Series I. External pin contact crimped on wire. Seri
11、es II. External socket contact crimped on wire. b. Classes. Terminal junction components described herein are Class D. Classes A, B, and C components are inactive for new design. Class D components shall be used for direct Government acquisition. Appendix A provides performance tests and other infor
12、mation relating to Classes A, B, and C. Appendix A indicates the relationship between Class D part numbers and the superseded part numbers of Classes A, B, and C. Series II components of AS81714 meet Class D environmental requirements. 1.3 Marking Identification The components covered by this specif
13、ication shall be identified by a part number, as shown by the applicable detail specification. Series I components shall be identified as in the following examples, or as otherwise specified (3.1).
