Abstract
A securing part and an unscrewing safeguard system of a gradient coil plug for an MRT that can be fixed to a gradient coil bushing include a gradient coil plug, a gradient coil bushing, a cap nut with a keyed surface and, to secure the gradient coil plug to the gradient coil bushing, a multi-tooth ring fixed to the plug so that the ring cannot rotate, and a securing part with a multi-tooth ring engagement contour that can be brought into engagement with the multi-tooth ring, and with a keyed surface engagement contour that can be brought into mating with the keyed surface of the ring.
Claims19
A safeguard system that prevents unscrewing of a plug connection assembly, comprising:
- a plug having a connection end;
- a bushing having an internal configuration that receives said plug connection end;
- a cap nut on said plug that secures said plug to said bushing, said cap nut having a keyed surface;
- a multi-tooth ring non-rotatively fixed to said plug;
- and
- a securing part comprising a multi-tooth ring engagement contour configured to engage said multi-tooth ring, and having a keyed surface engagement contour that mates with said keyed surface of said cap nut.
A securing part that prevents unscrewing of a plug connection assembly having a plug having a connection end, a bushing having an internal configuration that receives said plug connection end, and a cap nut on said plug that secures said plug to said bushing, said cap nut having a keyed surface, sais securing part comprising:
- a multi-tooth ring non-rotatively fixed to said plug;
- and
- a securing part comprising a multi-tooth ring engagement contour configured to engage said multi-tooth ring, and having a keyed surface engagement contour that mates with said keyed surface of said cap nut.
A gradient coil connection assembly comprising:
- a gradient coil terminating a plug having a connection end;
- a gradient coil receptacle having a bushing having an internal configuration that receives said plug connection end;
- a cap nut on said plug that secures said plug to said bushing, said cap nut having a keyed surface;
- a multi-tooth ring non-rotatively fixed to said plug;
- and
- a securing part comprising a multi-tooth ring engagement contour configured to engage said multi-tooth ring, and having a keyed surface engagement contour that mates with said keyed surface of said cap nut.
