Problems solved by technology

[0013] That is, compared with the fixed contact on the side receiving contact pressure, the male contact on the side that provides contact pressure tends to have a shorter service life due to repeated insertion or removal of the contact.
Therefore, if a male contact with a short life is provided on the connector on the side of the electronic device, the electronic device must be partially disassembled in order to exchange the connector, which is not preferable.

Abstract

A miniature multi-polar electric plug which can prevent the male contacts from being placed unprotected all the time is provided. An electric plug (10) has a plug housing (1), male contacts (2) , a shutter (3) , a shell (4) , and a pair of compressed coil springs (5). The plug housing (1) has a header part (1a) and a frame part (1b). The header part (1b) protrudes from the frame part and has a mounting board (12) for mounting the male contacts (2) and the shutter (3). The compressed coil springs (5) move the shutter (3) to cover or uncover the male contact (2).

Description

technical field [0001] The invention relates to an electrical connection plug. Background technique [0002] Recent electronic devices, such as mobile phones, micro cameras, and portable information terminals, use a connection stand (also called a cradle) called a cradle when transmitting and receiving data with a desktop personal computer. [0003] While installing the plug in the cradle, a cable is connected via which the cradle and the desktop personal computer are connected. On the other hand, an interface component is installed in an electronic device such as a portable information terminal, and the interface component provided on the side of the electronic device is connected to the plug provided in the bracket, so that the electronic device and the desktop personal computer can be quickly and accurately connected. transfer data. The simplest case of the cradle is a charger for a mobile phone. [0004] Conventionally, such a cradle is unique to electronic equipment ...
