The present invention relates to a micro USB connector plug, and more particularly to a micro USB connector plug having a vertical ground piece protruded at one side of a rear side, a metal shell having a horizontal ground piece protruded at one side of the vertical ground piece, And a horizontal grounding piece is contacted to one side of the rear end of the grounding end so as to provide a double contact structure. Even if one of the contact portions is not deformed, the other contact portion is contacted The grounding through the double contact structure can be made more stable, unlike the conventional single contact structure, and the connection terminal and the metal shell due to the withstand voltage when connecting to the micro USB connector socket, A short circuit can be prevented It relates to a lock micro yueseubi connector plug.

Generally, a micro USB connector plug allows a portable terminal such as a mobile phone to input / output data using a USB bus, and is connected to a micro USB connector socket provided for input / output of data to / from a portable terminal.

Here, a micro USB connector socket provided in a portable terminal such as a cellular phone typically comprises a socket mold in which a socket connection portion is protruded, and a socket housing to which the socket mold is coupled so that a plurality of socket connection terminals .

The conventional micro USB connector plug used in connection with such a micro USB connector socket is composed of a plug mold in which a plug connection portion is protruded and a metal shell which is coupled to enclose a plug connection portion of the plug mold, A plurality of plug connection terminals are inserted into the plug mold at a front end portion of the connection portion so that a plug connection end formed in front of the plug connection terminal to be in contact with the socket connection terminal of the micro USB connector socket is exposed.

That is, the micro USB connector plug is used by being connected to the socket of the micro USB connector through a plug connection end protruded upward from the front end of the plug connection terminal, in contact with the socket connection terminal.

However, the conventional micro USB connector plug as described above has a problem that a short circuit occurs between a metal shell and a plug connection terminal which is in contact with a socket connection terminal due to a high withstanding voltage. A short circuit is generated between the terminal and the metal shell, thereby causing safety accidents and parts breakage.

In order to solve the above problems, a micro USB connector plug as shown in Patent Document 1 (registered in Korean Registered Patent No. 1265270, May 31, 2013, registered by the present applicant) is provided.

The conventional micro USB connector plug as shown in the above Patent Document 1 is provided in a portable terminal such as a mobile phone and has a socket connection terminal, a socket mold having a socket connection part on one side, and a micro USB connector socket including a socket housing.

In such a conventional micro USB connector plug, an elastic ground terminal is provided on the upper side of the central portion of one of the plug connection terminals, and the elastic ground terminal is in contact with the inner surface of the metal shell in the vertical direction.

In other words, the conventional micro USB connector plug as described above has a problem that the elastic ground terminal is in contact with the inner surface of the metal shell, and it is difficult to distinguish whether the connector is a product to which the grounding structure is applied after assembling the connector plug.

In addition, since the grounding structure is unstable due to the structure in which the elastic grounding end is grounded only in the vertical direction with respect to the inner surface of the metal shell, improvement is required in a more stable grounding structure.

As a conventional technique for preventing a safety accident and a component from being damaged due to a short circuit between a plug connection terminal and a metal shell, there has been proposed a plug assembly having a spark prevention function (Patent Document 2: Registration No. 1355163, April 17, 2014) is provided.

However, the plug assembly having a spark-preventive function, which is provided as a conventional micro USB connector plug, has one end of the cover of the pin holder bent in the vertical direction and horizontally contacting with the upwardly protruding portion of the ground pin, The grounding structure is unstable and it is required to improve the grounding structure more stably.

Further, when one end of the cover of the pin holder is bent in the vertical direction and is in horizontal contact with the upward protruding portion of the ground pin, if the deformation of the bent portion of the cover of the pin holder in the vertical direction occurs, There is a problem that the formed portion is not brought into contact with the upward projecting portion of the ground pin.

Therefore, even if one of the contact portions is not deformed by the double contact structure, the other contact portion can be brought into contact with the ground. Therefore, unlike the conventional single contact structure, the grounding through the double contact structure is more stable The research and development of a micro USB connector plug is required.
