Description

Plug connector

The present invention relates to a plug connector, and more particularly to a plug connector that can be applied to a front and back plug.

The most popular signal transmission specification for today's computer equipment is the Universal Serial Bus (USB). The connector socket and transmission line made by this specification can be connected to the peripheral devices of the computer, such as a mouse and a keyboard. Instantly measured for your computer and used immediately. Since the current standard USB plug has only one row of contacts on one side, and the USB socket is provided with a row of contacts on one side of the tongue, the USB plug needs to be inserted in the correct direction to make the contacts of the two contacts. And to reach an electrical connection. In order to ensure that the USB plug can be electrically connected when inserted, the two have a foolproof design on the docking, that is, when the USB plug is inserted in the reverse direction, the user cannot insert it, and the user will insert another direction, and the direction is correct to insert. The user usually inserts randomly, so the probability of not being inserted is 1/2, so it is often inserted twice, causing inconvenience in use.

For related prior art, please refer to the Republic of China Patent Publication No. TWM370848, which discloses a USB plug connector suitable for forward and reverse insertion. The plug connector has a rectangular metal casing, and a printed circuit board having a conductive device in the center of the casing, and the printed circuit board divides the inside of the metal casing into two symmetrical and equal accommodating spaces. Four printed circuits with conductive properties are printed on the printed circuit board, and four printed circuits with conductive properties are printed on the lower end of the printed circuit board. When the USB plug is inserted into the USB socket of the computer host positively, the receiving space of the upper end of the USB plug can be inserted into the copper plastic plate of the USB socket, and the printed circuit of the USB plug printed circuit board and the USB socket copper plastic plate The printed circuit below is in contact to conduct current. When the USB plug is reversed (upside down) into the USB socket of the host computer, the other end of the USB plug has a receiving space for the copper wire plastic board of the USB socket, and the printed circuit of the other end of the USB plug printed circuit board Then, it is in contact with the copper wire under the USB socket copper plastic plate to conduct current. The metal casing is a one-piece rectangular body that completely surrounds the printed circuit board, which may cause inconvenience and incomplete installation during assembly.

Therefore, it is necessary to provide a new plug connector to overcome the above drawbacks.

The purpose of this creation is to provide a plug connector that is easy to assemble and that can be secured in place.

In order to achieve the above object, the plug connector of the present invention comprises an insulating body, a conductive terminal held in the insulating body, a shielding shell assembled on the outside of the insulating body, a printed circuit board welded with the conductive terminal, and partially covered and formed in the shielding. An insulating housing outside the housing and a cable soldered to the printed circuit board to be electrically connected to the conductive terminal, the shielding housing including a laterally extending front retaining wall and two side walls extending longitudinally from opposite ends of the front retaining wall, the guiding slot The rails are disposed on two side walls of the shielding shell, and the rails are disposed on two sides of the insulating body, and the rail groups are assembled in the guiding slots.

Compared with the prior art, the present plug connector has at least the following advantages: since the shielding shell of the plug connector comprises a laterally extending front retaining wall and two side walls extending longitudinally from opposite ends of the front retaining wall, the two side walls are provided with guiding grooves. There are protruding rails on both sides of the insulating body. When installing, the rail group is installed in the guiding groove, which has the advantages of convenient assembly and installation in place.
