Abstract

There are often a few RJ-11 telephone cables with broken locking tabs lying around in every household. It is a pity to throw them into the garbage. Some recyclists may still want to use the cord by fastening them with masking tape or rubber bands etc. This creates an unreliable communica- tion phone systems. The same problem exists in network hook-up as well. With increasing usage demand of Globally connected computers like the Internet, Local Area Network and Wide Area Network, network connection reliability becomes ever more important. An improved RJ-45 or R&xx design is described in the following paragraphs.

MORE RELIABLE NETWORK CONNECTORS

INTRODUCTION

  There are often a few RJ-11 telephone cables with broken locking tabs lying around in every household. It is a pity to throw them into the garbage. Some recyclists may still want to use the cord by fastening them with masking tape or rubber bands etc. This creates an unreliable communica- tion phone systems. The same problem exists in network hook-up as well. With increasing usage demand of Globally connected computers like the Internet, Local Area Network and Wide Area Network, network connection reliability becomes ever more important. An improved RJ-45 or R&xx design is described in the following paragraphs.

CURRENT DESIGN

  As shown in Figure 1, the locking tab (latch) can be easily stretched beyond its elastic limits and therefore be weakened permanently which eventual- ly leads to breakage. The stretching normally hap- pens when somebody tries to sort out tangled cords in a hurry or tries to feed the cord through a hole in the wall or conduit etc.

IMPROVED DESIGN

  The simple and efficient but easily broken tab will be replaced by a more complicated but more reliable sliding mechanism as shown in Figure 2. The sliding mechanism will have smooth outside comers and edges (detail #I) with a trapezoidal guiding track (detail #2) to ensure that the slide will stay in place when travelling back and forth on the connector plug. The slide also needs two travel lim- iters (basically two small bumps or restrictions, detail #4) to keep the slide from over-travelling and falling apart. The sliding mechanism will indirectly compress the nylon or plastic tab to unlock the con- nector (detail #3). The nylon can be made to rebound to its natural equilibrium position to lock

the connector in the receptacle. There will be no charge in the receptacle design because the dimen- sions of the locking portion of the new tab can be made the same as the current design.

BENEFITS OF THE NEW DESIGN

1. The sliding piece of plastic (let's call it the key) may be completely removed from the connector by pulling it past the second travel limiters of the con- nector as shown in Figure 2.
