Apparatus having an integral coaxial antenna coupled via a coaxial connector to its internal circuitry has a coaxial switch/connector for alternatively coupling an external coaxial signal source to the internal circuitry, thus reducing impedance mismatch to a minimum with no impedance matching network required.

Coaxial dual antenna connection arrangement for communications apparatus

A console for charging a portable communications device and converting it for mobile operation can accommodate portable units of varying lengths. The contacts for the charging current are positioned by the insertion of a portable unit by means of a unique reel mechanism. Interconnection and latching are also activated by the insertion of the portable unit. The converter connector serves as a part of the latching and locking apparatus which makes the unattended portable essentially theft proof.

Charger/converter console with reel arrangement

A carrying device for an elongated portable article has a back plate with an integral portion forming a loop for receiving the article, with a stop surface adapted to be engaged by a ledge on the article. The device includes a latch secured to the back plate having a projection cooperating with a part of the article to hold the article in the device. The device can be adapted to carry a portable radio having controls on the top and side and a grille at the front, with the ledge being below the side control. The controls and the speaker grille are not obstructed when the radio is being carried. The device can be used to carry radios which vary in length and in other respects, which are of a size to be positioned within the loop and which have a ledge and a part at a fixed position with respect to the ledge to cooperate with the latch. A belt loop or other mounting element can be attached to the device for supporting the same.

Carrying device for portable article

An improved subminiature electrical connector arrangement especially suited for miniature electrical or electronic apparatus. The connector arrangement includes a two-piece female connector assembly wherein one part thereof may be suitably interconnected to the circuitry of the apparatus while the same is outside the associated housing. This connector may then be placed in alignment with an opening within the housing and a second connector portion inserts within the opening and makes a snap-fit, weather tight seal therein and engages said first connector portion, all without special tools or any additional hardware. An associated male connector plug makes a convenient interconnection with the female assembly by including a hook-like projection overhanging one edge thereof and which engages a recess in the top of a housing to permit the male plug to rotate downwardly and inwardly into correct mechanical and electrical engagement with the female connector assembly. The male plug further includes a plurality of contact spring elements with sidewardly extending projections which make wiping engagement with associated contact members in the female connector assembly and which exert a sidewise force therein so that, upon release of the associated fastening means securing the plug to the housing in its interconnected position, the sidewise spring bias forces the male plug at least partially out of the female assembly for an automatic disengagement and eject facility.
