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. Part 3: Removing Wires with Crimped Power Connectors from a Housing 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. 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. 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. Relay manufactures evolved from a slightly different discipline and show the pin out looking at the bottom of the relay.Part 1: Stripping the Wire and Adding the Power Connectorsīegin by using a wire stripping tool to strip back enough wire, ensuring proper connection when crimping on the power connectors. PCB footprints are almost always shown looking top down at the part as it would be mounted. Compare to "common knowledge" or standards online.
#4 pin molex connector pinout drivers#
Mark which pins are drivers and which are receivers. Look at the drawing for each connector, make sure it's clear that the connections are shown looking from the top or bottom or looking into the connector or behind the connector, etc. I always sit down and draw this stuff out when reviewing a design. Ribbon cables can be assembled in four different ways for each connector.
#4 pin molex connector pinout serial#
RS-232 serial ports can be a real nightmare. Even if the same plug is used on the both ends of a cable, if it is not wired symmetrically, then you need to make sure you don't reverse the connection ends. Once you go to a cable or wire harness all bets are off. Generally, there is a mating pair of connectors and their pin numbers are going to match, so that pin 1 on a PCB mounted jack is going make an electrical connection to pin 1 on a cable mounted plug.
Connectors are a common source of error in a design.
