Abstract

The utility model discloses a Micro-USB plug connector, comprising a body, a plurality of conductive terminals and a snap mechanism. The conductive terminals are assembled on the body. The snap mechanism has an insertion portion, one end of the insertion portion is bent and extended to have a first elastic arm and a second elastic arm, the upper end of the second elastic arm protrudes upward to form an abutment portion, and the end of the second elastic arm forms a snap portion. The snap mechanism is assembled on the body, and the abutment portion and the snap portion both protrude from the body. Since the abutment portion protrudes from the body and abuts against the Micro-USB socket connector, when the Micro-USB plug connector is subjected to external force, the abutment portion can prevent the Micro-USB plug connector from moving up and down to avoid unstable signal transmission between the Micro-USB plug connector and the docking Micro-USB socket connector.

Description

Micro-USB plug connector

Technical field

The utility model relates to a Micro-USB connector, in particular to a buckle structure of a Micro-USB plug connector.

Background technique

With the continuous development of electronic products, various electronic products and their peripheral devices are connected more and more frequently, and the connection between electronic products and their peripheral devices is generally realized through a USB connector. Due to the miniaturization of electronic products, in order to reduce the volume occupied by USB connectors on electronic products and peripheral devices, Micro-USB connectors are generally used. The Micro-USB connector includes a Micro-USB plug connector and a Micro-USB socket connector, and the connection between the electronic product and its peripheral devices is realized through the connection of the Micro-USB plug connector and the Micro-USB socket connector.

In order to ensure a firm connection between the Micro-USB plug connector and the Micro-USB receptacle connector, the Micro-USB plug connector generally has a buckle mechanism. Referring to FIG. 1 , it discloses a snap mechanism 70 of a conventional Micro-USB plug connector. The buckle mechanism 70 has a U-shaped sheet holding portion 71 , and a tail portion 72 extends backward from the middle of the holding portion 71 . One end of the holding portion 71 extends forward and obliquely downwards with a first elastic arm 73 , the end of the first elastic arm 73 is slightly inclined upward and extends forward with a second elastic arm 74 , and the end of the second elastic arm 74 forms a buckle portion 75.

When the Micro-USB plug connector is inserted into the Micro-USB socket connector, the buckle mechanism 70 is engaged on the Micro-USB socket connector to prevent the Micro-USB plug connector from falling off from the Micro-USB socket connector. However, since the second elastic arm 74 of the buckle mechanism 70 is in an upwardly inclined shape, the electrical contact between the Micro-USB plug connector and the Micro-USB socket connector can be caused when the Micro-USB plug connector is subjected to a small external force. The connection is suddenly disconnected, which causes the signal transmission of the Micro-USB connector to be unstable or even interrupted.

Utility model content

The purpose of this utility model is to provide a Micro-USB plug connector with a stable electrical connection with the Micro-USB socket connector for the above-mentioned defects in the prior art.

To achieve the above purpose, the Micro-USB plug connector of the present invention includes a main body, several conductive terminals and a buckle mechanism. The main body has a base and an extension. A storage channel is opened on both sides of the base; a storage groove communicating with the storage channel is opened on both sides of the extension. Conductive terminals are assembled on the body. The buckle mechanism has an inserting portion, one end of the inserting portion extends obliquely downwards to a first elastic arm, the first elastic arm extends upwards and forwards obliquely to a second elastic arm, and the upper end of the second elastic arm protrudes upwards to form a There is an abutment portion, and the end of the second elastic arm protrudes upward to form a buckle portion. The inserting part is accommodated in the accommodation channel of the body, the first elastic arm and the second elastic arm are both accommodated in the accommodation groove of the body, and the abutting part and the locking part protrude out of the accommodation groove.

As mentioned above, the Micro-USB plug connector of the present utility model forms a planar abutment part on the buckle mechanism, and the height of the abutment part is higher than the second elastic arm, so that when the Micro-USB plug is connected When the device is subjected to external force, the entire surface of the abutting part is pressed against the docking Micro-USB socket connector to provide a supporting force, so that a stable electrical performance can be achieved between the Micro-USB plug connector and the Micro-USB socket connector connection, thereby preventing the Micro-USB plug connector from moving up and down relative to the Micro-USB socket connector, thereby avoiding unstable signal transmission between the Micro-USB plug connector and the corresponding Micro-USB socket connector.
