J COVER
•
T
his shielding cover is made of steel, formed by our advanced stamping
technology, and nickel-plated.
•
The box-shaped cover completely encloses such EMI radiating areas as the connections
between the connector and wires. The result is a superior shielding effect.
•
To install the shielding cover, simply align and press the upper and lower cover
elements, then tighten the nuts. It then securely grips the round cables.
•
This cover is so compact, light and sturdy, that it can be used to cover the
connectors of any input/output cable. Moreover, it is attractive in appearance.

J-cover assembly procedure
J series JK series
Assembly procedure
1. Connect wires to the connector by soldering or crimping.
2.
Fold back the braided shielding wire along the outside insulation
and wind the copper foil tape around the shielding wire.
3. Install the connector into shielding cover A.
4. Screw the lock screws onto shielding cover B.
5. Install the E-rings.
6. Align shielding cover B with shielding cover A and press shielding
cover B until it engages the lances of shielding cover A.
7. Tighten the cover nut until the predetermined position is
reached.
Note: For details of the J-cover assembly procedure, please refer to the
processing specifications separately available. The shielding effect of
the J-cover is critically dependent on proper assembly.

• This cover completely encloses all wire connections to the
connector, and its braided wire crimp section ensures a reliable
ground connection. The result is excellent shielding.
•
This cover is sturdy enough to withstand the high pressure
necessary during overmolding. It can thus be finish-molded directly
.

Assembly procedure
1. Processing braided shielding wire
Pass the cable through ferrule B and remove the insulation at
the end of the cable. Install ferrule A and fold back the braided
shielding wire along the outside insulation. Then wind the
copper foil tape around the shielding wire.
2. Connecting the wires to the contacts
Connect the wires to the contacts by crimping and insert the
contacts into the housing.
3. Assembling the mold covers
Align mold cover B with mold cover A and press mold cover B
until it engages the lances of mold cover A. Install ferrule B
over the cable holding section of the cover assembly and crimp
ferrule B. This completes the assembly.

Application examples of hexagonal lock screw blocks
• The resulting total dimension from the connector flange to the top
of the hexagonal lock screw block must be 6.2mm after
assembly.
• The D subminiature connector can be installed on the Panel by
simply tightening the hexagonal lock screw block together with
grounding adapter, which has an identical thread to that of the
F, G, and H types.
With this tool, contacts (connected to wires by crimping) can be
easily removed if they are improperly inserted into plug and
receptacle housings.
