Pins and sockets crimptool (gauge 12-26)
In aircraft wiring we use connectors and receptacles to make easy sepparation of wiring possible.
The wiring that connects to the connector or the receptacle must be terminated with a pin or socket that locks inside the connector/receptacle.
There are different methods to crimp pins and sockets onto wiring. The tool I will use in this example is the M22520/1-01 (military specification).
We have this tool from 2 manufacturers. One from ASTRO (615708) and one from the Daniels Manufacturing Corporation 'DMC' (AF8).
For this demonstration I will use the ASTRO 615708.
his tool holds different turrets that can be set to different contact gauges (thickness).
Mostly we use the M22520/1-01 with a M22520/1-02 turret (pretty much the standard turret for most standard wires and contacts).
Let's say we'd want to crimp a 'red' sized contact with the M22520/1-02.
We take the ASTRO 615708 (M22520/1-01) and we take the ASTRO 615709 (M22520/1-02) turret.
The rotatable wheel setting on the crimptool set's the depth of the crimp on the contacts.
So we set the 'setting' selector to AWG 22 because that is the diameter of the conductor. (pull the dial to rotate it).
The code under the gauge (code 3 for gauge 22) is the code that we found in the Standard Wiring Practices Manual earlier.
The diameter setting on the turret is now set at 'blue' and we need to crimp a 'red' size contact.
So I push the release latch.
I rotate the diameter selector to 'red'.
And I press the selector back in to select the 'red' size.
On the turret there should be a placard informing u of wich diameter setting to use with certain engaging end sizes and crimp barrel sizes.
See the pins and sockets section for more about engaging end size and crimp barrel size.
When the proper selections are made u strip the wire to the correct length.
Insert the contact with the wire into the 1-01 crimptool.
Crimp the contact.
And now the contact is ready to be inserted into a connector.
If we want to use another turret, we loosen these two allen screws to remove the turret.
