- Page 2 408-35338 Introduction SDE Crimp Commercial Hand Tool Assembly 2439520-1 for the PicoMQS contact is the tool and die set shown in Figure 1. The tool consists of the SDE Crimp Frame Assembly 2362810-1 (instruction sheet 408-35143) and the die assembly listed in Figure 1. This tool is used to crimp the terminal part numbers listed in Table 1.
- Page 3 408-35338 Installing the die set and locator assembly. Open the tool handles. Remove the two die-retaining screws from the tool jaws (see Figure 1). Assemble the floating shear and shear return spring to the combination anvil. Insert the assembled combination anvil and floating shear in the moving jaw of the tool frame with the chamfered side facing outward.
- Page 4 408-35338 Crimping NOTE The tool is provided with a crimp adjustment feature. Initially, the crimp height should be verified as specified in Figure 5 Refer to section 6, Inspecting the crimp height, and section 7, Adjusting the ratchet, to verify crimp height before using the tool. Select a wire of the correct size and insulation diameter for the terminal (see Table 1).
- Page 5 408-35338 Figure 3: Crimping Spring loaded locator blade Wire conductor position Wire insulation position Close the handles of the tool until the spring-loaded locator blade is touching the contact. (See Figure Insert the wire into the crimp barrel of the contact until it butts against the spring-loaded locator blade. While holding the wire against the radius in the floating shear, fully cycle the tool until the ratchet releases and allows the handle to open.
- Page 6 Crimp height inspection is performed using a micrometer with a modified anvil, commonly referred to as a crimp-height comparator. TE Connectivity does not manufacture or market crimp height comparators. Detailed information on obtaining and using crimp-height comparators can be found in instruction sheet 408-7424.
- Page 7 408-35338 Adjusting the ratchet The ratchet is preset prior to shipment, but it is important to verify the crimp height using a micrometer or caliper. Use and wear can cause the tool to go out of adjustment. Inspect the crimp height and adjust the ratchet, if necessary, on a regular basis.
