Abstract

The present invention provides a fixing device; the device comprises at least one fixing hole used for a fixing bolt passing through and located in a flange which is provided with at least one notch at the edge of the fixing hole. Moreover, the diameter of the fixing hole is less than the outer diameter of the screw thread of the fixing bolt. Therefore, the elastic material characteristics of the flange are used fully; accordingly, certain forces are needed to screw the fixing bolt into the fixing hole or from the fixing hole. Therefore, the fixing device can ensure that the fixing bolt will not release from the fixing hole even under continuous vibration for a long time, that is to say, the fixing bolt is hold in the fixing hole in a non-losable manner, which has great significance for the following condition, wherein the fixing device comprises a grounding member of a plug connector; the grounding member has the flange, and the grounding member is configured to joint and locate an insulator, and mount on the shell of the plug connector integrally with the insulator for transportation.

Description

technical field [0001] The invention relates to a fastening device comprising a flange and at least one threaded fastening screw, wherein the flange has at least one fastening hole with a predetermined diameter, and the fastening screw passes through the fastening hole. Background technique [0002] The function of this fixing device is to hold the fixing screw until it is finally installed in the corresponding fixing hole. In particular, such a fastening device comprises a grounding part belonging to the plug connector, which grounding part has such a flange. Such grounding elements are arranged to be engaged and positioned within an insulator and to be mounted with the insulator on the plug connector housing for shipment. In this case, it is desirable that the at least one fixing screw is held indelibly in the fixing hole of the flange so that it cannot be lost during transport. [0003] In the prior art, document DE 10310164 discloses, for example, that the fixing screw...
