3.96 mm Pitch Miniature Connectors for Internal Power Supplies (UL,C-UL and TV Listed)
DF7 Series
2004.7
s
Features
1. Complete Locking Function
Reliable interior lock protects mated connectors from
accidental disconnection.
2. Increased Contact Retention of Crimped
Contacts and Prevention of Incomplete
Insertion
Separate contact retainer increases the contact
retention, assures and visually confirms the complete
contact insertion.
3. Molded-in Contact Retention Tabs
Handling of terminated contacts during the assembly and
termination is easier and avoids entangling of wires,
since there are no protruding metal tabs.
4. Incorrect Insertion Prevention
Connectors are polarized to assure correct mating with
corresponding parts.
5.Solder Crack Prevention
Glass reinforced resin is used in the pin header bodies to
prevent solder cracks caused by the heat shrinkage.
6. Prevention of Incorrect Board Placement
Built-in locating posts assure correct connector
placement and orientation on the board.(2-12 pos.)
7. Supports Sealing after Installation.
Sealing compound can be applied to the board installed
connector for distance of 6 mm max. from the mounting
surface (9 mm max. for single position).
8.Cost Effective Tooling
The same crimping tools are used to terminate socket
and pin contacts.
9. Prevention of Shor t Circuits between
Adjacent Contacts
Each contact is completely surrounded by the insulator
housing, electrically isolating it from adjacent contacts.
