1. SCOPE:
This document describes the design and asmbly force guidelines for conventional and mechanical assist (lever and slide-lock) electrical connectors and CPA’s.
开心歌All possible designs and applications cannot be anticipated in creating the guidelines.
Where there are questions of adherence to this document, such as u of an “off-the-shelf”
design, always consult the responsible Ergonomics department.
Refer to SAE/USCAR-12 Wiring Component Design Guidelines for additional guidelines.
2. REFERENCED DOCUMENTS:
1. SAE/USCAR-2 Performance Specification for Automotive Electrical Connector Systems
2. SAE/USCAR-12 Wiring Component Design Guidelines
3. GENERAL:
In all cas, ASSEMBLY FORCES SHOULD BE AS LOW AS POSSIBLE while maintaining satisfactory electrical, mechanical, and environmental performance.
Part packaging, process and workstation design requirements/constraints may require a reduction in maximum forces specified in this document. Consult with the OEM ergonomics department in the cas. Such situations include but are not limited to:
1. Obstructed access
2. Limited visibility
3. Awkward or non-neutral postures, especially wrist deviation
4. DESIGN GUIDELINES – MECHANICAL ASSIST CONNECTORS:
Mechanical assist type connectors u levers, cams, or slides to allow incread electrical capability with less ergonomic stress. Asmbly forces up to 75N are allowable for such connectors provided the guidelines are met. Lever-lock or mechanical assist connectors fall into three categories as shown in table 4.1. Required touch contact area and asmbly force varies with each category.
FIGURE 4.1.1: Lever Contact Surface Area Example
4.1.2 An end stop is defined as a ridge perpendicular to the bearing surface located at the
distal edge of the surface. Such features are OPTIONAL and may help prevent the
thumb/finger(s) from sliding off of the lever. Maximum dimensions of this feature are
shown in figure 4.1.2

4.2 Maximum Asmbly Force:
The maximum allowable asmbly force is the peak force required to actuate the lever from its fully opened position to it’s fully locked position. Forces at any point in the path may not exceed the maximum force shown in table 4.1.
4.3 Dingage Force:
Dingagement of the connector in the asmbly plant may be required for testing. In
the cas, values for the maximum disasmbly force with the condary lock or CPA relead are the same as the maximum asmbly force for each category (table 4.1).
4.4 Connector Pre-Lock:
4.4.1 The pre-lock position allows positioning of the connector prior to actuation of the lever
assist.
4.4.2 Design the connector so that the force required to fully engage the connector into its pre-
lock position complies with the hand-plug connector requirement (ction 6) of this
document
4.4.3 Design the pre-lock and lock features to give audible and or tactile feedback
4.5 Inadvertent Actuation:
4.5.1 Design lever mechanisms to prevent inadvertent actuation during shipping, handling, and
pre-asmbly operations. Refer to USCAR-12 for specific guidelines.
4.5.2 Design connectors so that it is visually obvious to the operator that the connector is not
correctly ated and locked.
4.5.3 Design the lever mechanism so that if the connector is not ated properly or the

polarization is incorrect, the force to actuate the lever meets SAE/USCAR-2 (Polarization Feature Effectiveness test).
4.6 Asmbly Access:
4.6.1 Keep the swing area of the lever clear of sharp edges or objects that may catch a
thumb/fingernail.
4.6.2 Hand access clearance for category 3 connectors only is defined in Figures
5.1.1-1 and
5.1.1-2.
