## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector assembly, and more particularly to a connector assembly having an electrical connector and a printed circuit board electrically connected with the electrical connector.
2. The Related Art
With the development of electronic technology, electronic products are required to be miniaturized more and more. Therefore, a connector assembly assembled in the electronic product is required to occupy a space as small as possible in the electronic product. The connector assembly includes a printed circuit board and an electrical connector. However, the electrical connector and the printed circuit board are assembled together traditionally by locating the electrical connector on a surface of the printed circuit board. This causes the connector assembly to occupy a larger space in the electronic product so that the electronic product is unfavourable to be miniaturized. Therefore, a connector assembly capable of miniaturizing the electronic product in size largely is required.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a connector assembly. The connector assembly includes a printed circuit board defining an inserting window penetrating forward through a front edge thereof and a plurality of soldering holes adjacent to two sides of the inserting window, and an electrical connector assembled in the inserting window of the printed circuit board. The electrical connector includes an insulating body having a base portion and a tongue portion extending forwardly from a front of the base portion, a plurality of terminals disposed in the tongue portion of the insulating body and each having a soldering arm levelly extending rearward to stretch out of a rear surface of the base portion, and a shell having a top board, two facing side boards and two butt-joined bottom boards of which rear edges are provided with a plurality of mounting portions. The rear surface of the base portion defines a plurality of mounting fillisters. The insulating body together with the terminals is inserted in the shell, with the base portion being secured in a rear of the shell by means of the mounting portions buckled in the mounting fillisters respectively, and the tongue portion being spaced from periphery insides of the shell to define an inserting space therebetween for receiving an external mating connector. Each side board has a substantial middle thereof punched outward to form a soldering board extending levelly, and a lower part of the rear edge thereof punched outward and then bent downward to form a soldering tail inserted downward in the corresponding soldering hole of the printed circuit board. The soldering boards of the shell and the soldering arms of the terminals are flush with one another to be levelly against and further soldered onto a top face of the printed circuit board.
As described above, as the electrical connector is disposed in the inserting window of the printed circuit board, not only the height of the connector assembly but also the space occupied by the connector assembly in an electronic product are reduced. Therefore, the electronic product can be miniaturized in size more and more. Moreover, the electrical connector is electrically connected with the printed circuit board by means of the soldering tails of the shell being inserted in the soldering holes, the soldering boards of the shell and the soldering arms of the terminals being levelly soldered onto the printed circuit board, so that achieves a steady connection between the electrical connector and the printed circuit board. The mounting portions of the shell are buckled in the mounting fillisters of the insulating body to further realize a firm assembly of the shell and the insulating body.

In this embodiment, the mounting portions include a first mounting portion 321 bent downward from a middle of a rear edge of the top board 32, two second mounting portions 331 bent towards each other from upper parts of rear edges of the side boards 33, and two third mounting portions 341 bent upward from substantial middles of rear edges of the bottom boards 34. Each side board 33 of the shell 30 has a substantial middle thereof punched outward to form a soldering board 35 extending levelly, and a lower part of the rear edge thereof punched outward and then bent downward to form a soldering tail 36.
The insulating body 10 has a rectangular base portion 11 mating with a rear of the shell 30 and a board-shaped tongue portion 12 extending forwardly from a middle portion of a front of the base portion 11. A top side of the tongue portion 12 defines a plurality of terminal cavities 13 arranged at regular intervals along a transverse direction thereof and each further extending rearward to pass through the base portion 11. A rear surface 110 of the base portion 11 defines a plurality of mounting fillisters. In the embodiment, the mounting fillisters include a first mounting fillister 111 opened in a middle of a top of the rear surface 110 of the base portion 11 and further penetrating upward through a top edge of the base portion 11, two second mounting fillisters 112 concaved towards each other from upper parts of rear side edges of the base portion 11, and two third mounting fillisters 113 apart opened in a bottom of the rear surface 110 and further penetrating downward through a bottom edge of the base portion 11. A middle of each third mounting fillister 113 further penetrates forward through the front of the base portion 11 to form a fastening fillister 14.
