Feature
Made by others
Hirose HR31
Crimped and connected to terminal then
fastened simply by inserting into housing.
Plug height is 10.2 mm, allowing use of less
space when mounting several connectors
Permanently identified contact positions
No need for screws, built-in locking pin secures
connector to the board
Crimped to commercially available cap
Reduced number of termination
connectors, inserted into housing and
operations
fastened by screw. (*)
High density mounting
Prevention of connection errors
Number of required operations
to secure receptacle assembly
to the board
Plug height : 15 mm
Contact positions not identified.
Connectors are attached by screws from
the opposite side.
*Although it is possible to terminate discrete cables with screws and not use a pin contact, however, there is the potential issue
and concern for long-term reliability and problems. Therefore, most users prefer to use crimp contacts.
2. Screw-lock style
The screw lock style connector features secure mating and
a higher locking force retention.
Total space occupied by mated
assemblies
3. Snap-lock Style
The snap lock plug features a structure that creates a tactile
click during mating.

Tools application procedures
1. Manual contact crimp tool
The tool will terminate all specified crimp contacts. Placement of correct contact in
corresponding crimp position on the tool is critical. The positions are clearly indicated on the tool
as (2) and (1.25). The exposed conductor strip length is 5mm.

2. Contact removal/extraction
Wiring errors can be corrected by removing the crimp contacts using the extraction tool and the
following procedure.
1) Insert the extraction tool from the underside of connector and apply pressure onto the mold
lance. (Fig.1)
2) While pressing on the mold lance, angle the extraction tool and release the disconnection
prevention mechanism on the crimping contact. (Fig.2)
3) Remove the extraction tool.
4) Pull the wire rearward to disconnect and remove the contact.
