PERFORMANCE SPECIFICATION FOR AUTOMOTIVE RF CONNECTOR SYSTEMS

2023-07-10

CURRENT

USCAR17-6

This document contains procedures for testing performance of SMB-style electrical terminals, connectors and components for coaxial cable connection systems intended for road vehicle applications. These are often called FAKRA II designs. This specification does not apply to the Non RF portion of a Hybrid RF connection system. The intent of this specification is to qualify sealed and unsealed RF connectors that operate at frequencies from DC to 6 GHz. The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification does not exclude the use of these RF connectors on non-50 ohm cables or systems. This specification does not apply to single conductor wire or twisted pair connection systems. This specification (along with SAE/USCAR 18) is designed to provide the mechanical and electrical data required to insure that assemblies from various manufacturers will perform reliably in actual conditions.

PERFORMANCE SPECIFICATION FOR AUTOMOTIVE WIRE HARNESS RETAINER CLIPS

2023-03-23

CURRENT

USCAR44-2

This specification describes a method and acceptance criteria for testing automotive wire harness retainer clips. Retainer clips are plastic parts that hold a wire harness or electrical connector in a specific position. Typical plastic retainers work by having a set of “branches” that can be inserted into a hole sized to be easy to install but provide acceptable retention. This specification tests retainer clips for mechanical retention when exposed to the mechanical and environmental stresses typically found in automotive applications over a 15-year service life. This specification has several test options to allow the test to match to the expected service conditions. The variability of applications typically arises from different ambient temperatures near the clip, different proximity to automotive fluids, different exposure to standing water or water spray, and different thicknesses of the holes that the clip is inserted into.

The characteristic impedance of the Mini-Coax connection system described here is 50 ohms, however nothing excludes the use of these connectors in systems with a different characteristic impedance. This specification applies only to connection systems using coaxial cable.

TEST PROCEDURE FOR ELECTRICAL GROUND ATTACHMENTS

2022-02-25

HISTORICAL

USCAR26

This test procedure is intended to evaluate and/or validate electrical ground schemes for use on the body or chassis. There are two classes based on the expected environmental conditions. Exposed Grounds can be located anywhere in the vehicle (except on the powertrain) and is the class for which most schemes should be tested. Unexposed Grounds can only be used in the passenger compartment or trunk and as such are special cases. This procedure as written is not intended for testing powertrain grounds where high temperatures and vibration levels may be encountered. These situations may require modifications to this procedure and are left to the Responsible Engineer to determine. This specification does not specifically address validation of terminal to wire electrical crimps. Crimps are tested to SAE/USCAR-21

ERGONOMICS SPECIFICATION FOR MANUALLY SEATED FASTENERS

2020-12-30

CURRENT

USCAR47

This document describes the assembly force guidelines for manually seated push-pins, clips, and similar retention devices. For the purpose of this document, the term “clip” is used to reference all retention devices addressed within this document. Applicable retention devices must have force exerted directly to the clip using the finger/thumb and are hand seated independent of other fasteners. For a retention device to be manually installed and seated independent of other retention devices, it must be seated fully without any interaction with an adjacent fastener (i.e., multiple PIA clips on the back of a hard trim panel). This standard applies to contact surfaces angled at 90 degrees (±10 degrees) and/or perpendicular from the direction of force insertion. Mechanically installed fasteners (screws, rivets, etc.) are not included in this document. This standard does not apply to extraction/retention forces.
