Connectors - Two-steps
Overview | One-step | Two-steps | ZIF/LIF-Compatible
GENERAL
When GGI International uses this type of connector, it is usually either a Crimpflex or AMP series. The mounting principle for this type of connector is achieved by firstly installing the pins on the circuit tail extremity followed by the assembly of the molded plastic receptacle/housing. Reliable electrical contact is achieved by piercing the conducting trace during the crimping operation at 6 points; 2 points for the mechanical retention and 4 for the electrical contacts.
- Characteristics:
- Available genders: Male (pins only) or Female (pins + receptacle)
- Number of positions: minimum = 2/maximum = unlimited
- Number of rows: 1 or 2
- Distance between positions: 2,54 mm (0,100")
- Connection counterparts:
- Female sockets accepting 0.64 mm (0.025") square or round pins
- 0.64 mm (0.025") square or round pins
- Locking: available
- Multiple insertions: yes
- Polarization: available
- RoHS compatibility: available
- Advantages:
- Economical
- One pin type can be used for several types of receptacles
- Virtually no stress on width because the receptacles can be placed right next to one another
- The receptacle can be removed after its installation without damaging the circuit
- Setting of all contacts is done simultaneously
- Disadvantages:
- Requires two step assembly
- Contact is optimal on one pin side only
- No identification of Pin #1 on the receptacle
- Fragile contact on membrane keypads having more than one circuit
Important note for polarized or locking connectors:
Since the pins installed on GGI International's circuits have a direction of optimal contact and include a latch for positive insertion in the receptacle, particular attention must be given to polarized or locking receptacles. The orientation of the receptacle depends on the direction of installation of the pins. By default, GGI International installs pins in the direction of optimal contact. Consequently, the polarization or locking orientation of the receptacle is determined by the pin orientation.
If this type of receptacle is used, it is very important to notify us of the polarization or locking orientation desired. Knowing this, we will place the pins on the circuit ensuring that the receptacle is in the proper direction. If this information is not provided or is likely to change, it is strongly recommended to advise GGI International as to the orientation of the connector in order to obtain an optimal electrical contact.
