socket

Abstract

The invention provides a socket, capable of reliably detecting the plugging of a plug no matter where the grounding electrode of the plug is located. The socket (1) is provided with a switch mechanism inside the electrically insulating socket housing having a plug inserting hole. The switch mechanism is composed of at least one signal contact, a first switch contact (8) provided with a first contact portion (8c1), and a second switch contact (9) provided with a second contact portion (9c1) that contacts with the first contact portion, wherein the first and second switch contacts utilize the conductive and elastically deformable arm sheets to form the switch contact (9) of one party; with the insertion of the plug into a plug patchhole (3), the plug slidingly contacts with the switch contact formed by the arm sheets and generates displacement; and the first and second switch contacts are provided with an electrically insulating propelling member (10) that makes the contact portions of the switch contacts move.

Description

technical field [0001] The present invention relates to a socket that is a connector for inserting and connecting a plug to an earphone or a microphone, and more particularly, to a socket having a plug insertion detection mechanism capable of detecting that a plug is inserted into a plug insertion hole. Background technique [0002] Outlets having a plug insertion detection mechanism are known, and the plug insertion detection mechanism is roughly classified into the following two types. One type is to detect by electrically connecting the electrodes of the plug with contacts provided in the socket housing, and the other is to provide a switch mechanism in the socket housing and perform detection based on the operation of the switch mechanism. [0003] The former type is disclosed, for example, in Patent Document 1 below. The plug insertion detecting device of this patent document 1 is as Figure 14A , 14B As shown, among the 4-pole terminals 17 to which the 3-pole plug 15...

Problems solved by technology

However, in the former improved method of these improved methods, a dedicated socket is required for each type of plug with different positions of the grounding electrodes. Therefore, it is necessary to prepare a socket for each type of plug, resulting in an increase in variety and troublesome management. cost increase

In addition, in the outlets of Patent Documents 2 and 3, it is difficult to change the position of the switch mechanism. If the switch mechanism is forced to be changed to a position close to the plug insertion port, noise may enter the ear through the earphone when the plug is inserted.

In addition, the latter improvement method is to assemble multiple plug detection mechanisms, and this assembly method leads to an enlarged socket, a complicated structure and an increase in cost, so it cannot be practically applied
