Features –––––––––––––––––––––––––––––––––––––––––––––––––––––––––
• The socket contacts are formed by high-speed stamping presses
to obtain the advantages of cold working. They are therefore
highly elastic, which in turn ensures reliable connection even after
many mating cycles.
• The dimples in the plug shell ensure continuity between it and the
socket shell, thus providing complete shielding.

• Costs are kept low by selective gold plating the contacts.
• The solder cup portions of the contacts are tin-plated for easy
soldering.
• Insulator housings are made of a heat-resistant glass-filled PBT
resin.

Features –––––––––––––––––––––––––––––––––––––––––––––––––––––––––
• The contacts of this plug are formed by high-speed stamping
presses into continuous strips that can be automatically fed into
our compact crimping machines. Much less time is required to
assemble CRT and RS-232C round cables using this plug than
when soldering connections.
• The contacts in this connector are selectively gold-plated.
Moreover, JST's advanced technological knowledge and
experience are fully utilized to significantly reduce production
costs.
• The dimples in the connector shell provide the ground connection
and are important factors in preventing electromagnetic
interference. The contact has a lance that can be visually
checked during assembly. This assures accurate assembly and
reduces defects.

• 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.

MOLD COVER
Features –––––––––––––––––––––––
• 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.
* Refer to "General Instruction and Notice when using
Terminals and Connectors" at the end of this catalog.
* Contact JST for details.
* Compliant with RoHS.

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.
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.
2. Connecting the wires to the contacts
Connect the wires to the contacts by crimping and insert the
contacts into the housing.
