Miniature Push-Pull Connector with Earth Function, MXR Series
Caution
Product Description
This is a small round connector with ground functionality. The single-action push-pull lock enables quick removal.
[Features]
• Single-action push lock function enables quick insertion and extraction, and high density implementation is also available.
• The mating confirmation and "snap" sound ensure proper operation for a lock method with a solid feel.
• The exterior utilizes aluminum alloy for the purpose of weight reduction.
• After mating is complete, the exterior metal components provide stable contact points for FCC support.
• Sequence structure type available for making contact with a single core first during mating.
• There is a type available with a plug cable that can only be clamped to the locked-in section of the cord pipe, with the goal of dedicated tool reduction for improved workability.
• There is a type available with a plug cable that can only be clamped to the locked in section of the cord pipe, with the goal of dedicated tool reduction for improved workability.

Product Termination Procedure
MXR-8PA-3PB(71), MXR-8PA-4PB(71), MXR-8PA-6PB(71)
Work Procedure
- 1. Pass the cable through the components in the order of cable bushing, plug body and then clamp and terminate the cable end.
- 2. After inserting the P shell unit into the tightening jig, solder the contact wires to the P shell unit.
- 3. Align the concave portion of the P shell unit with the convex portion of the clamp and install.
- 4. After aligning the clamp with the position of the cable sheath strip, tighten the plug main body to the threaded portion of the P shell unit with a torque of 1 N·m.
Note that to prevent loosening, an application of Loctite 263 (by HENKEL JAPAN LTD.) is recommended. - 5. Put the cable bushing over the plug body to complete.
Concave portion of P shell unit / P shell unit / clamp / 7 or more / convex portion of clamp / plug main body / cord bushing / cable / spanner spacing 9.5
