1. Field of the Invention
The present invention generally relates to an electrical connector, and more particularly to an electrical connector mounting on a circuit board and to facilitate slight movement after which is soldered thereto.
2. Description of Related Art
Electrical connectors are widely used to interconnect electronic components and subcomponents to circuit boards to form functioning devices. In the condition of repeatedly mating and unmating with corresponding complementary connectors or circuit boards, the connections between the contacts of the connector and the circuit board may not be reliable. It is conventional to use auxiliary elements such as fasteners/screws mounted to the electrical connector and the circuit board to enhance such connection therebetween. Obviously, the connector is needed to be able to be adjusted during fixing process by screw. However, it is difficult to make the gap between the screw hole and contacts absorbed because the electrical connectors are immovable after soldering.
Hence, an improved electrical connector is desired to overcome the problems mentioned above.
Accordingly, an object of the present invention is to provide an electrical connector which is movable after soldering to a circuit board.
In order to achieve the above-mentioned object, an electrical connector for mounting to a circuit board includes a dielectric housing defining a mounting face confronting to the circuit board and a top face opposite thereto and a plurality of conductive contacts. The dielectric housing defines a plurality of passageways extending therethrough and opened to the top face. Each conductive contacts has a body portion secured in the passageway of the dielectric housing, a mating portion extending from one edge of the body portion and beyond the top face, a stretch portion extending from the other edge of the body portion, and a solder portion connected with the stretch portion and extending outside of the dielectric housing. The stretch portion is deflectable with respect to the circuit board after the conductive contacts being soldered on said circuit board.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe the present invention in detail.

The stretch portion 23 is a general slanted S-shaped and defines a first U-shaped portion 231 and a second U-shaped portion 232 to allow movements in X, Y, and Z directions, Z representing an up and down movement relative to the circuit board in which the electrical connector is mounted, and X and Y representing movements in the plane parallel to the circuit board in which the electrical connector is mounted all as represented by the arrows shown in

After the conductive contacts 20 soldering to the circuit board, the mating portion 21 can move in the Z direction and the solder portion 24 is immovable relative to the circuit board. But as can be appreciated, slight movement is provided by the spring characteristics of the stretch portion 23 and is intended within a range of the elastic properties of the spring. Therefore, the electrical connector 1 can adjust position of which to overcome the mounting tolerance of the process of the solder and result in an accurate orientation for fixing a fastener to further securing the electrical connector the circuit board.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
