Miniature Push-Pull Connector with Earth Function, MXR Series
Brand :
HIROSE ELECTRIC
Caution
Product Description
A small lightweight circular connector with earth function. Uses aluminum alloy for the exterior.
[Features]
· The single-action push-lock mechanism facilitates quick mating and un-mating and allows for high-density mounting.
· The metal on the exterior is in stable contact.
· When mating, there is a sequence structure type where only one core contacts first.
· Plugs in which the tightening of cord tubes can be performed just by clamping the cable are also available.
· These are designed to enhance workability and reduce the need for dedicated tools.
[Applications]
· Convenient for various types of wiring.

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
