Abstract

Disclosed is a microphone clip connecting structure mainly including a microphone back cover having a round recess, a rotational disk rotatably received in the round recess, and a clip assembled to the rotational disk. A plurality of locating holes and a sunken hole deeper than the locating holes are spaced around the round recess. The rotational disk has a retaining hook and a retaining block at each side of its top surface, defining a mortise space between them. A locating projection extends from a bottom of the retaining block into one of the locating holes or the sunken hole. When the rotational disk is turned with the locating projections extend into two of the locating holes, the rotational disk is temporarily fixed in place. And, when one of the locating projections extends into the sunken hole, its corresponding retaining block on the rotational disk can be easily depressed to allow a tenon on the clip to pass over the retaining block and into the mortise space between the retaining block and the retaining hook, so that the clip can be easily assembled to the rotational disk and accordingly the microphone back cover.

Claims

1. A microphone clip connecting structure, comprising a back cover of a microphone, a rotational disk, and a clip;

said back cover being formed on an outer surface with a round recess for receiving said rotational disk therein, said round recess having a central hole and a plurality of locating holes and a sunken hole said plurality of locating holes and said sunken hole equally spaced around said central hole, said rotational disk also having a central hole axially in alignment with said central hole on said back cover, said rotational disc being rotatably connected to said back cover in said round recess by a rivet extended through said two central holes, said rotational disk being formed on a top surface with a pair of upward projected retaining hooks and slightly flexible retaining blocks, said retaining hook and said retaining block being so designed that they together define a mortise space between them;

a locating projection extending from a bottom side of each said retaining block and forming an integral part of each said retaining block;

said sunken hole having a depth larger than that of said locating holes to allow a larger or deeper space for said locating projection to vertically move therein;

whereby, when said clip is assembled to said rotational disk by pushing a side tenon on said clip over a top of said retaining block, said retaining block being allowed to lower further due to said deeper sunken hole and therefore permitting said tenon of said clip to pass over said retaining block and into said mortise space between said retaining block and said retaining hook.
