Abstract: A shielded connector assembly having an insulating housing having front and rear parts, and female connector parts. Contacts are disposed in the female connector parts. A metal shell is attached to the insulating housing. The metal shell has a specified plate thickness and has grounding tongues that elastically contact mating male connectors that are connected to the female connector parts. A front shell made of metal is externally mounted on the front part of the insulating housing. The front shell has a plate thickness thicker than the metal shell and is fastened to the insulating housing by crimping such that it contacts the metal shell. A metal rear shell is externally mounted on the insulating housing from the rear part of the insulating housing such that the front shell and the rear shell are mechanically and electrically engaged with each other.

Abstract: Lower carboxylic acids such as acetic acid, are produced efficiently from inexpensive lower alkanes such as methane by allowing the lower alkanes to react with carbon monoxide in the presence of palladium and/or copper catalysts and salts of peroxy acids.
