Filter device

摘要

The present invention relates to a filter device, the filter device includes a housing provided with a through-hole; and a filter structure includes a signal line; a wave filter connected to the signal line, the size of the periphery of the wave filter smaller than the diameter of the through-hole; a connecter connected to one end of the signal line and connected electrically with the wave filter; wherein the filter structure is arranged from the outside of the housing through the through-hole correspondingly, so that the signal line and the wave filter are arranged at the inside of the housing and the connecter is fixed at the through-hole. Hence, the filter structure is locked and fixed optionally from the outside or from the inside of the housing to increase the convenience of the whole assembly.
