1. Field of the Invention
The present invention generally relates to a battery connector, and more particularly to a battery connector capable of making terminals and a printed circuit board electrically connected with each other steadily.
2. The Related Art
It is well known that mobile phones or other portable electronic devices often use rechargeable batteries as power sources. Traditionally, the mobile phone and the electronic device need a battery connector mounted therein for electrically connecting the rechargeable battery with a printed circuit board mounted in the mobile phone and the electronic device. The battery connector is connected with the printed circuit board by soldering terminals thereof to the printed circuit board by means of a SMT method. However, when the terminals are not coplanar due to the inaccurate manufacturing, some terminals near the printed circuit board are easily soldered to the printed circuit board while other terminals apart from the printed circuit board are difficultly soldered to the printed circuit board. It results in a bad electrical connection between the terminals and the printed circuit board. Thus a battery connector which can make the terminals and the printed circuit board electrically connected with each other steadily is required.
An object of the present invention is to provide a battery connector adapted for being electrically connected with a printed circuit board. The battery connector includes an insulating housing defining a plurality of terminal passageways passing through a top surface and a bottom surface thereof and extending longitudinally, a plurality of fixing members fastened in the insulating housing and stretching beyond the top surface of the insulating housing for being soldered to the printed circuit board, and a plurality of electrical terminals disposed in the corresponding terminal passageways. Each of the electrical terminals has a fixing board disposed vertically, a first contact portion stretching out of the bottom surface of the insulating housing, and a substantially lying-V shaped second elastic portion extended from a top of the fixing board. A free end of the second elastic portion stretches out of the top surface of the insulating housing and is arched upward to form a second contact portion capable of elastically abutting against the printed circuit board.
As described above, the battery connector and the printed circuit board are electrically connected with each other by way of the second contact portions of the electrical terminals elastically abutting against the printed circuit board because of the elasticity of the second elastic portions in order to ensure a steady electrical connection between the battery connector and the printed circuit board even if the second contact portions are not coplanar due to the inaccurate manufacturing.
The present invention will be apparent to those skilled in the art by reading the following description of a preferred embodiment thereof, with reference to the attached drawings, in which:
With reference to
The insulating housing 10 is of rectangular shape and has a top surface 11, a bottom surface 12, two side surfaces 13, a front surface 14 and a rear surface 15. A middle of the insulating housing 10 defines a plurality of substantially rectangular terminal passageways 16 arranged at regular intervals along a transverse direction thereof and each vertically passing through the top surface 11 and the bottom surface 12. A front of each terminal passageway 16 extends toward two sides to form a pair of fixing fillisters 161. A top front of each of the terminal passageways 16 extends forward to penetrate through the front surface 14 and the top surface 11 to form a locating cavity 17. A top of each side surface 13 protrudes outward to form a rectangular first fixing block 18 adjacent to the front surface 14 and extending beyond the top surface 11. Each of the first fixing blocks 18 defines a first fixing aperture 181 vertically passing therethrough. Two top ends of the first fixing blocks 18 extend face-to-face to form a pair of preventing boards 182 spaced away from the top surface 11. Accordingly, a pair of guiding channels 183 is formed between the corresponding preventing boards 182 and the top surface 11. A top of the rear surface 15 protrudes rearward to form two rectangular second fixing blocks 19 extending beyond the top surface 11 and apart from each other. Each of the second fixing blocks 19 defines a second fixing aperture 191 vertically passing therethrough.
