Scope
AS81714 covers Terminal Junction System (TJS) components which 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 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 maximum specified for the class of TJS component, unless otherwise specified (1.2, 3.1). The maximum continuous temperature established by the electronic components in a component module (block) shall be limited to the block maximum continuous temperature. The components making up the system and covered by AS81714 include:
-
a
Terminal junction bussing blocks (6.12.2)
-
1
Feedback type (6.12.2.1)
-
2
Feedthrough type (6.12.2.2)
-
1
-
b
Racks (mounting holders) for blocks (6.12.3)
-
c
Brackets, block mounting (6.12.4)
-
d
Wire in-line junctions (6.12.5)
-
e
Grounding terminal (6.12.6)
-
f
Grounding blocks (6.12.7)
-
g
Electronic blocks (6.12.12)
-
h
Electronic in-line junctions (6.12.9)
Rationale
Revision required to correct references, improve QC requirements, address spare contacts, and minor technical changes.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
