Measure the angled portion of the wire bundle only 15 x 2(2) = 60 mm per side Total Surface Area 60 + 60 = 120 mm SAE/USCAR-25 REVISION 3 Revise
9、d 2016-03 ERGONOMICS SPECIFICATION FOR ELECTRICAL CONNECTIONS - 20 - Appendix C: CPA (Connector Position Assurance) Evaluation Examples Example 1- Unobstructed CPA: 3 Sides (Acceptable Condition) A minimum of 3x5 mm of the CPA push surface must be free of any obstructions with the connector body or
10、wires on at least 3 sides through the length of travel. Example 2- Unobstructed CPA: 3 sides with Angled push surface (Acceptable Condition) The angled CPA push surface allows 3 mm minimum dimension above the side walls (3x5 mm is available). Note: Angle (30-90 deg.) must be positively sloped in the
11、 direction of force insertion. A negatively sloped angle (91-180 deg.) does not qualify.

12、 (Acceptable Condition) No opposing surfaces/ walls. 3x5 mm push surface available. Example 4- Obstructed CPA: 2 Opposing Sides (Acceptable Condition) The CPA push surface, above the side walls, is less than the required 3mm dimension in this example. An acceptable design solution requires 15 mm hor
13、izontal distance between the side walls with a CPA travel distance 7 mm, 19 mm would be required between side walls.

14、cted CPA: 2 Opposing Sides (Unacceptable Condition) The CPA is fully recessed between the opposing walls. There is no accessibility for the finger to engage the CPA as the distance between the side walls is less than 19 mm. SAE/USCAR-25 REVISION 3 Revised 2016-03 ERGONOMICS SPECIFICATION FOR ELECTRI
