Description

Fixing device to secure an RJ-interface
The invention relates to a fixing device according to the preamble of an independent claim directed thereto for securing an RJ interface.
RJ (Registered Jack) connectors are commonly used in telephone, data terminal and data transfer services, and particularly in industry, e.g. in various process control services or the like, noteworthy examples of the available RJ connector types being:
- RJ10 (4/4) = 4-pin,
- RJ11 (6/4) = 4-pin (wide, like RJ12),
- RJ12 (6/6) = 6-pin,
- RJ45 = 8-pin (UTP, STP) , and
- RJ48 = 10-pin 10/10 (UTP) .
In the foregoing, the code UTP (Unshielded Twisted Pair) stands for unprotected and STP (Shielded Twisted Pair) for protected.
RJ-interface is used e.g. in desktop computers, WiFi routers, switches, firewalls, and in numerous other computer network components, generally speaking in interconnection between an electric actuator' s RJ port and an RJ connector-equipped cable . In this case, practical problems are mainly caused by "slackness" of the RJ coupling as a mechanical connection between the RJ port and the RJ connector allow a small movement of an RJ connector-equipped cable, resulting disorders in electrical contact between the RJ port and the RJ connector . Thus, e.g. a detachment of the network cable is possible, which in practice may result in difficult-to-detect malfunctions.
In industry, Ethernet-based fieldbuses include e.g. Ethernet/IP, Profinet, Ethercat, etc. One noteworthy practical example of the RJ interface problem in industry, regarding e.g. inverter operations for engines or actuators, is interconnection between one or more RJ communication cards and an RJ cable connect- able thereto, the former being releasably connectable to the control unit of a programmable logic control- ler/PLC and/or an inverter, said interconnection being exposed to both vibration and contaminants emanating from the environment . Here, electrical contact disturbances result in undefined malfunctions, entailing at worst a restart of the process equipment should the electrical contact be cut off.
In the foregoing context, the elimination of vibra- tion-induced problems, among others, has been attempted by using between a programmable logic controller and one or more RJ communication cards re- leasably connectable thereto a rubber seal, nevertheless without achieving a decisive improvement as it is not possible to thereby secure the interconnection between a communication card and an RJ cable connectable thereto.
It is the objective of a fixing device of the present invention, intended for securing an RJ interface, to provide decisive improvement regarding the foregoing problems and to thereby raise substantially the available state of the art. In order to attain this objective, the fixing device according to the invention is principally characterized by what is presented in the characterizing clause of an independent claim directed thereto.
As the most important benefits of. a fixing device according to the invention should be mentioned the simplicity and effectiveness of its construction and employment, it being by virtue of a fixing device, which is extremely simple in construction, easily manufactured from a material most appropriate for each given application, and quickly installable to its service position, that it will be possible to eliminate some of the disorders and service disrup- tions caused by electrical contact problems occurring in data transmission.
The fixing device of the invention enables prevention of e.g. vibration-induced disorders, especially in connection with so-called rolling stock and/or in applications exposed to vibration. In addition, the invention inhibits vandalism and prevents inadvertent detachments of RJ cables. In attaching the fixing device to each given electric actuator and to one or more RJ cables connectable thereto, it is possible to utilize a mutual crimp joint and/or screw locking thereof by making use of e.g. cooling vents included in the actuator or by simply using e.g. a cable tie when connecting the cable. Further, by virtue of adjustment elements utilized in the invention, the fixing device lends itself to being used in connection with a most diversified range of electric actuators differing from each other especially in terms of the width thereof.
