Removing the wires without damaging the connectors is a simple method of enabling users to switch the polarity of actuator wires without needing to obtain additional Molex connectors or Molex housing. Once the header pins push back the hooks, Molex connector pin removal is simple, and the wire can slide out of the housing by pulling back on it without causing any damages to the power connector. This is completed by pushing the header pin into the thin gap between the metal power connector and the plastic on both sides of the housing. In this tutorial, we are using flat header pins that are used to release the hooks. Since there are two hooks keeping the connectors in place within the housing, they will need to be pushed back to release the wires. I believe the 4-pin molex connector is the auxiliary power connector, and if the original poster replaced the power supply with a new 24-pin connector (instead of the old 20-pin one), then you shouldnt need the square, 4-pin molex. Part 3: Removing Wires with Crimped Power Connectors from a Housing nmliz : I had the same question and found the answer here. However, there is a method of removing the wire from the housing without damaging the power connector. Once the crimped wire has been inserted into the housing, it will be difficult to remove. The power connectors have hooks that allow the connectors to latch into the connector housing. To disconnect a Molex connector (male and female connection), simple press down on outside clip and pull the connectors apart. Try crimping the wire again and inspect the crimp before inserting it into the housing. If the power connector pulls out or the wire comes loose, it means that your crimp was faulty. There are two housing options available, namely, a male housing (female power connectors) and a female housing (male power connectors). For example, a Progressive Automations control box may require the actuator wires to have a designated orientation to obtain an extend and retract sequence that correlates to the ‘up’ or ‘down’ activation buttons on a wireless remote.

Choose molex connector kits in 2, 3, 4, 6, 9, 12,15 pins. The orientation of the wires can be based strictly off preference and will depend on the Molex wiring required for the type of system that you are working with. Molex Connectors, 2-15 circuits are in-stock at Parts Express. The crimped wires can now be fed into the connector housing. Part 2: Adding Wires with Crimped Power Connectors to the Connector Housing Clamp down on the crimping tool and release.Įnsure the correct power connector is crimped onto the wire depending on if you use Molex connectors that are male or female.

With the stripped wire inserted into the un-crimped power connector, load it into the crimping tool.Īlternatively, insert the un-crimped power connector into the crimping tool without the wire, and then feed the wire into the connector (either way works). Therefore, the optimal length of exposed wire is 2.5 mm (the length of the crimp zone).

The amount of exposed wire should not exceed the length of the power connectors insulation and crimp zone, which is 5mm.

Includes a pass-through at the Molex connector(male/female) so you don't lose a power connection. This OKgear 4-pin Molex to 3-pin fan adapter is ideal for connecting your 3-pin (only two pins are used, the 12v and Grnd) computer fans directly to your computer's power supply unit (PSU) if you do not have an available motherboard header. 20818 OKgear 4-pin Molex Pass-Through to 1 x 3pin Male Computer Fan Connector 4 Inch Sleeved 0.99 0.9900 USD InStock /Cables/Fan/MOBO Adapter Cables 2-10-Pin This OKgear 4-pin Molex to 3-pin fan adapter is ideal for connecting your 3-pin (only two pins are used, the 12v and Grnd) computer fans directly to your computer's power supply unit (PSU) if you do not have an available motherboard header.
