9.1.1 Hardware Mounting - Jackpost - Height
This section covers the height relationship of the face of the jackpost to the associated connector face. This is critical to obtain maximum connector pin contact.
Hardware stack-up for mounted connectors may be varied in order to locate the face of the jackpost flush to ±0.75 mm [0.030 in] below with the face of the connector.
Acceptable – Class 1,2,3
Jackpost face is flush to ±0.75 mm [0.030 in] below with the face of the connector. Height is obtained by adding or removing
washers (supplied with jackpost).
Defect – Class 1,2,3
Jackpost face extends above the connector
face (620A Figure 9-2).
Face of jackpost is more than ±0.75 mm [0.030 in] below with the connector face (see Figure 9-3).
9.1.3 Hardware Mounting – Retaining Clips
Acceptable – Class 1,2,3
Retaining clip is properly oriented. Screw is completely through threaded
portion of the clip.
Retaining clip (620A Figure 9-NEWE2 A)
is properly oriented
Defect – Class 1,2,3
Retaining clip is improperly oriented (threaded side of clip is on the mating side of connector flange).
o Flat side of retaining clip is not oriented on the mating side of the connector
o Upside down (620A Figure 9-NEW4)
Screw is not completely through the
threaded device. Figure 9-1 Figure 9-2 Figure 9-3 Figure 9-5 Figure 9-6 Figure 9-7 Figure 9-8

9.1.4 Hardware Mounting – Connector Alignment When torque requirements are established, see 17.2.
When the connector/backshell/accessory uses teeth to interlock the mating surfaces, the connector assembly procedures shall [D1D2D3] include a process that ensures the teeth are fully engaged prior to tightening. Figure 9-9 shows an acceptable mating where the alignment teeth are fully engaged. Figure 9-10 shows two examples of teeth that are not fully engaged. The locking ring is removed in these illustrations to show the condition; the interlocking teeth are not visually inspectable.
9.2.1 Strain Relief – Clamp Fit
Clamps, as specified on the drawing, shall [D1D2D3] support cables, harnesses or individual wires to prevent wire movement that may place strain on the wire/connector terminations. Split lock washers incorporated as part of the backshell or strain relief clamp shall [D1D2D3] be fully compressed.
If the number of wires terminating into the connector is insufficient to allow the strain relief clamp to grip the wires properly, then insulating tape, sleeving or a grommet of an approved material shall [D1D2D3] be used to “build-up” the bundle diameter to provide contact and support between the cable and the strain relief clamp. The build-up material may also be required to provide protection of the insulated wires from damage caused by the connector clamp.
Build-up material is referred to as “sleeving” in the following criteria. The sleeving criteria apply only when such material is applied to the wire bundle. Build-up material, when used, shall [D1D2D3] be as specified on engineering documentation.
Spacers, when used, shall [N1D2D3] be as specified on engineering documentation.
Acceptable – Class 1,2,3
Sleeving is flush with the end of clamp (arrow).
There is space between at least 1 of the inner surfaces of a clamp and the backshell ear on 1 side.
Spacers, if present, are mounted under the
same adapter clamp on both sides of the cable.
Defect – Class 1,2,3
Sleeving extension beyond clamp causes stress on the wires (A).
The split lock washers are not collapsed (B). Clamps do not captivate and support the
cable.
Clamps do not prevent movement of the cable.
Damage to sleeving that exposes the harness or other protected material (not shown). Spacers, if required, are not present or are
not mounted under the same adapter clamp on both sides of the cable.
Splice or ferrule located under the backshell clamp.

9.2.2.1 Strain Relief – Wire Dress - Straight Approach
Process Indicator – Class 2,3 Defect – Class 3
Wire length is excessive outside the contour of the wire bundle (A).
9.2.2.2 Strain Relief – Wire Dress – Side Approach
Process Indicator – Class 2 Defect – Class ,3
Wire length is outside the contour of the wire bundle excessive (A).
9.3.1 Sleeving and Boots - Position
Not Established – Class 1 Process Indicator – Class 2 Defect – Class 3
Boot does not extend to the end of the first accessory attachment area.
9.4.2 Connector Damage - Limits - Hard Face - Mating Surface
Acceptable – Class 1 Process Indicator – Class 2,3
Connector face has been chipped but dielectric between seals is intact.
Chipping does not extend from 1 cavity to the outer diameter of any adjacent cavity.
Defect – Class 1,2,3
Chipping of the dielectric extends from cavity to the outside diameter of any adjacent cavity.
Crack extends from 1 cavity to another. Defect – Class 3
Any evidence of chipping or cracks in any
contact cavity. Figure 9-17

9.4.3 Connector Damage - Limits - Soft Face - Mating Surface or Rear Seal Area
Defect – Class 1,2,3
Cut, fracture or tear is in both the dielectric face and the extends beyond cup diameter.
Cut, fracture or tear that extends from cup through dielectric face or from 1 cup into another.
