Assembly #

Step 1 : Assemble Seal #

Assemble (1) cable seal retainer and (2) cable seal in the order and direction shown in the image above.

Note : Circuit numbers are shown on the cable seal retainer. Make sure that the correct cable is inserted into each cavity.

Step 2 : Strip Wire #

With the (1) cable seal retainer and (2) cable seal safely out of the way, strip the outer jacket and braided cable shield off of each cable

Step 3 : Strip Wire Again #

Strip the outer jacket further so that the combined exposed strip length of braided cable shield and conductor insulation matches above

Step 4 : Inner Ferrule #

Insert (3) inner ferrule onto each cable and over the outer jacket as shown in the image above

Step 5 : Fold Braided Cable #

Fold the braided cable shield back over the (3) inner ferrule, taking care to try to keep (3) inner ferrule positioned such that its edge is flush with the stripped edge of the outer jacket as shown in the image above

Step 6 : Strip Wire Again #

Strip the conductor insulation off each cable to the dimension defined by the specific plug connector

Step 7 : Receptacle Terminal #

Apply a (2) receptacle terminal to each cable using the tooling, method, and dimensions necessary for each specific plug connection. The trailing edge of the (2) receptacle terminal box should be located from the stripped edge of the outer jacket to the dimension given (approximately) in the image above

Step 8 : Outer Ferrule #

Insert (4) outer ferrule onto each cable in the orientation shown below and over (3) inner ferrule and folded back braided cable shield

Step 9 : Crimp #

Crimp each (4) outer ferrule using the necessary tool

Recommended Tool : SDE-SA Hand crimping frame assembly : this frame assembly accepts a die assembly designed to crimp the specific outer ferrule. (type 1: 6.80 mm HEX) and (type 2: 7.40 mm HEX) NOT INCLUDED

The distance between the leading edge of the outer ferrule and the trailing edge of the receptacle terminal box must be maintained at the dimension given above

Cable Inspection #

1Samples match examples shown in the images in this document
2Cables are inserted in correct cavity openings in seal retainer
3Seal is not rolled or damaged
4Outer jacket or conductor is not damaged
5No loose or protruding strands from braided cable shield and ferrule crimp
6Terminal crimp meets specified requirements
7Outer ferrule hex crimp is correct and outer ferrule is not damaged

Receptical Terminal Installation #

This section contains steps for installing the receptacle terminal into the plug connector

Step 1 : Orient Cable #

Orient the cable assembly so that the bridge feature on the cable seal retainer is aligned with the plug connector

Step 2 : Click Together #

Inset the receptacle terminals into their respective plug connector circuit cavities until they are fully locked, and an audible and tactile ‘click’ is detected

Note : The installation of the ferrule into the contact springs of the connector shield will cause some resistance, so it is important to verify that the receptacle terminals are fully inserted by pulling back lightly on the cables.

Step 3 : Fully Insert #

Fully insert the cable seal until it stops inside the back of the plug connector

Step 4 : Cable Seal Retainer #

Full install the cable seal retainer over the back of the plug connector, making sure that the bridge feature is correctly aligned with the plug connector latch feature. Verify that both locking features are fully engaged

Mating and Un-Mating #

Mating #

Align the plug connector and header assembly

Push the plug connector and header assembly together fully until they stop (two clicks will be heard). Verify that the plug connector and header assembly are fully locked with a light tug and by visually verifying the location of the indicator slot on the floating latch

Un-Mating #

Fully Depress the thumb actuation pad on the plug connector flexible latch (orange).

Pulll the plug connector back (approx. 4.5mm) into the intermediate position. At this point the HVIL circuit has been opened, but the HVIL terminals are still making contact

DO NOT PULL THE CABLES

Fully depress the thumb actuation pad on the floating latch (red)

Pull the plug connector until it is fully separated from the header assembly
