- the guide surface of the cable plug part is i.e. the surface of the made of elastic silicone rubber, EPDM or a similar insulation material manufactured inner cone plasma polymerized.
- Plasma polymerization becomes the lead surface networked so that their coefficient of friction and adhesion is greatly reduced. This leads to a slippery and non-stick surface, their beneficial Surprisingly, properties even after prolonged use - In a test series with the invention treated insulation bodies over 10,000 couplings, without changing the gliding behavior to be able to determine - remain.
- the plug contact parts are also more suitable Treated wisely. It has been shown that a silver graphite composite coating the above Can meet requirements.
- an insulating body made of elastic Modified quartz silicone rubber, i.e. coated with a known organosilicon compound. This allowed the coefficient of static friction that is full with elastic silicone rubber over 1, reduce to a value of approx. 0.2. At this coating technology surprisingly shows that the quartz-hard, highly cross-linked surface the elastic silicone rubber with repeated deformation maintains its sliding properties. this leads to the desired long-term separability.
- the elastic Silicone rubber-made insulation part of the device connection part a plasma-polymerized outer cone on.
- the advantages of the plug insulation according to the invention are immediately recognizable to the person skilled in the art and are essentially in the maintenance-free and non-adhesive guide surfaces to see.
- the guide surfaces basically need no longer being greased.
- the plug connection regardless of a regular Maintenance, i.e. will the Plug connections more user-friendly and more reliable.
- the plug insulation according to the invention Long-term separability achieved is suitable this especially for automatic coupling and decoupling of high-voltage couplings, as in High-speed trains are used.
- the insulating body 1 from an electrically insulating Cast resin made. This body is on the cable connector side shaped as an outer cone 6. Central in this outer cone 6, a metallic contact socket 12 is embedded, the one with the cable strands 5 electrically conductive wiring harness is connected. The insulating body 1 is fixed in a housing 3 and can with deflection. Field control electrodes 4 may be provided.
