The receptacle shall be placed in a location where it will not be exposed to road hazards either when connec
23、ted or loose. The receptacle leads must be properly routed and protected against damage from cutting and pinching where they leave the vehicle body. Extra insulation should be provided between the strain relief at the trailer hitch and the wiring assembly so that an abnormal pull on the plug will no
24、t damage the wiring. 3.5 No receptacle leads designated for lighting shall be smaller than SAE wire size 1 mm2(SAE wire size no. 16 gauge) minimum if a single conductor, or smaller than SAE wire size 0.8 mm2(SAE wire size no. 18 gauge) if a multiconductor cable. 3.6 No receptacle leads for brake cir

It is suggested that SAE J1128 Low Tension Primary Cable or Metric Wire stranded conductors for 12-V circuits should not exceed a 3% voltage drop (see Appendix A, Figures A1 and A2).
32、5.1 Exposed trailer wiring shall be run in conduits or secured at intervals not greater than 457 mm (18 in) to stop lateral movement and prevent rubbing or chafing. 5.2 So far as practicable, wiring should be located to afford protection from road splash, stones, or abrasion. Wiring exposed to such
33、conditions shall use additional tape, plastic sleeve, nonmetallic conduit, and/or other suitable shielding or covering to further protect the wiring. 6. HOUSING MATERIAL AND TERMINAL REQUIREMENTS 6.1 The receptacle and plug shall be made of an insulating material such that they can be processed to p
34、rovide the spacing and splash protection indicated in Figures 1, 2, and 3. 6.2 If the receptacles and plugs are fabricated of either molded or extruded plastic, the plastic material shall be stabilized for protection against exposure to ultraviolet light.6.3 Housing Material Types 6.3.1 Soft Molded
35、Plugs and Receptacles The hardness of a soft molded receptacle or plug shall fall between Shore A 50 and Shore A 85.6.3.2 Hard Molded Receptacles (tow-vehicle side) Hard molded plastics such PA and PBT.

FIGURE 4 - PIN SAE J1239 Revised SEP2010 Page 12 of 14FIGURE 5 - SOCKET 6.4.2 The terminal pins and receptacles shall be fabricated from a copper alloy material and suitably coated to protect against corrosion. Finished surfaces of terminal pins and interior walls of terminal receptacles shall be
38、 smooth so as not to bind when the parts are engaged. 7. ASSEMBLY REQUIREMENTS 7.1 The plug and receptacle of a four-way connector assembly shall disengage with a minimum force of 22.24 N (5 lb) and a maximum force of 88.96 N (20 lb) per assembly. 7.2 The plug and receptacle of a five-way connector
39、assembly shall disengage with a minimum force of 31.14 N (7 lb) and a maximum force of 111.2. N (25 lb) per assembly7.3 The plug and receptacle of an eight-way connector assembly shall disengage with a minimum of 35.58 N (8 lb) and a maximum force of 133.44 N (30 lb) per assembly. 7.4 The mechanical
40、 force requirements of disengagement do not preclude the requirements for good electrical connections between the male and female connectors of the circuits. 8. ALTERNATE CONNECTOR SELECTION This specification provides fundamental performance characteristics pertaining to mold-on connectors, which h
41、ave been established for Class I trailer applications. There is no intention to limit the application to the example four-, five-, and eight-way pin/sleeve connectors, provided that mating pair connectors have equal or superior performance characteristics. Also, additional performance standards for
42、connectors can be referenced in SAE J2223-1, SAE J2223-2, and SAE J2223-3. SAE J1239 Revised SEP2010 Page 13 of 149.
