UNIVERSAL USE OF SEALING PLUG FOR

MOBILE RADIO ACCESSORIES

by Werner Zuber

INTRODUCTION

  A standard mobile radio with an integrated speaker often has the option of connecting a micro- phone onto the front side of the radio housing. All additional mobile radio accessories are connected to the accessory connector, located on the rear side of the radio housing, e.g. Motorola ARIANE radio.

PROBLEM(S) TO BE SOLVED

  On certain versions of the Motorola ARIANE radio product, this accessory connector is not used and the opening is replaced with a flat rubber seal- ing plug, as shown in Figure 2, to close the connec- tor opening of the radio shown in Figure 1. Should a customer want to have additional accessories, maintaining the radio seal, a separate expanded sealing plug must be used, as shown in Figure 3. A first part of the expanded sealing plug attaches to the radio housing and protects the radio from water and dust particles. The second part of the radio is used to facilitate the accessory connector. The con- nector plug can then be used with a number of accessories, e.g. electronic adapters, fuse holder etc. An advantage of using the expanded sealing plug in Figure 3 is that it does not require any specific con-

SOLUTION TO THE PROBLEM(S)

  Figure 4 and 5 show the design of the enhanced sealing plug. The new sealing plug works for both of the previous situations. It is designed in such a way that it can be pushed as flat version shown in Figure 5 or pulled out to the expanded position as shown in Figure 4. When in the expanded position it is possible to...
