DESCRIPTION OF COMPONENT AND INTENDED APPLICATION. MMCX Coax connectors are micro-miniature RF coaxial connectors designed to the smallest dimensions. Significant space savings for densely populated electronic packages are possible, with the connectors giving a 45% space saving over equivalent SMB coax connectors. RF leakage is minimised by the non-slotted design and positive snap-fit coupling. Cable-to-board and cable-to-cable applications are possible. Jack (female) connectors are available in pcb mounted and straight crimp styles. Plug (male) connectors are available as straight or right-angled crimp versions. Jack connectors consist of beryllium copper inner contacts and brass bodies. Plug connectors comprise of brass inner contacts and bodies, with a beryllium copper spring latch for the snap-on coupling. Teflon is used for the insulating material. All metal components are gold plated. 2. MARKING OF COMPONENT AND/OR PACKAGE (ORDER CODE).

Outer Insulator Inner Conductor Inner Insulator Braid 2) Identify pieces of coax connector to be assembled. Body Sleeve Contact 3) Slide sleeve onto cable past stripped area. Sleeve 4) Crimp contact to end of cable inner conductor (see table below for appropriate crimp size). Contact Crimp here 5) Insert cable and contact into coax body from back end – make sure that the braid goes outside and over the end section. Body Braid 6) Slide sleeve back over the end of the coax body and the braid. Crimp into place on the cable insulation.

A2.2 ASSEMBLY INSTRUCTIONS FOR MMCX-6505 AND MMCX-6605 1) Strip cable to dimensions shown against relevant part (see appropriate engineering drawings). Braid Inner Conductor Outer Insulator Inner Insulator 2) Identify pieces of coax connector to be assembled. Body Sleeve Insulator Cover 3) Slide sleeve onto cable until it stops against the outer insulation. Fold the braid over the sleeve. Braid Sleeve 4) Push the cable and sleeve into the body, as far as it will go. The cable inner conductor will be visible through the hole in the top of the coax body, and should go into the slot in the inner contact of the body. Inner Conductor 5) Solder the cable inner conductor to the body inner contact. When cool, place the insulator inside the top, and press the cover into place. Crimp the back end of the coax onto the insulation of the cable.
