DETAILED DESCRIPTION

[0016] The disclosed embodiments relates to a fixing device to secure an RJ interface, which is intended for securing the interconnection between an RJ port la of an electric actuator 1 and a cable 2 provided with an RJ connector 2a in order to eliminate problems resulting from disturbances in electrical contact between the RJ port and the RJ connector. The fixing device x includes, in reference e.g. to an embodiment shown by way of example in FIG. 1, a frame member x1, wherein a first part of the frame member (x1) is configured to be immovably fixed to a first side of the actuator 1 with first fastening elements y1 and a second part of the frame member (x1) is configured to be immovably fixed to a second side of the actuator (1) with first fastening elements (y1), wherein the second side of the actuator (1) is the opposite side of the actuator (1) than the first side, so that a mutual crimp joint is formed around the actuator (1) when the actuator (1) is arranged between the first and second parts of the frame member (x1) of the fixing device (x) or the first and the second fastening elements (y1, y2) are immovably fixed in a ventilation opening or grate of the actuator (2) in the first and second sides of the actuator (1), and a support member x2 between the first and second parts of the frame member (x1) for having the RJ connector-equipped cable 2; 2a fixed immovably thereto with second fastening elements y2, wherein the frame member (x1) and the support member (x2) are made from rigid material.

[0017] In a preferred embodiment for a fixing device of the present disclosure, its frame member x1 and support member x2 are constructed as an integral entity, wherein the rigid material is a structurally rigid metal, plastic, reinforced plastic, ceramic, composite material and/or the like.

[0018] In a further preferred embodiment for a fixing device of the present disclosure, referring specifically to FIG. 1, its frame member x1 is provided with a fastening arrangement x4 for the first fastening elements y1 for coupling the fixing device in a screw-locked manner R to the actuator 1 and/or, as depicted in FIGS. 2 and 3, to a base supporting the actuator.

[0019] In another preferred embodiment for a fixing device of the disclosed embodiments, its support member x2 is provided with a fastening arrangement x5 for the second fastening elements y2 for coupling the fixing device x, e.g. in a screw-locked R manner according to a principle depicted in FIGS. 2 and 3 or e.g. in a cable-tied S manner according to a principle depicted in FIGS. 1 and 4, to the RJ cable 2.

[0020] In reference to the FIGS. 2 and 3, a fixing device may comprise adjustment elements T1 for adjusting a mutual distance between the first fastening elements y1 by means of one or more intermediate members x6, which interconnect the support members x2 present on opposite sides of the fixing device, are capable of being screw-locked R with threaded holes o″ included in the ends of the frame members to each desired length thereof, and are capable of having cut off those parts thereof which protrude from sliding holes included in the support members.
