DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 to 5, according to the present invention, the method for manufacturing an electrical connector, comprises the following steps: 1) inserting a wire 1 into a groove 20 formed in a guiding member 2; 2) passing the wire 1 along with the guiding member 2 through an elastomer 3. In this embodiment, the elastomer 3 is provided with a first hole 30 allowing the guiding member 2 to pass therethrough. Alternatively, as shown in FIG. 4, the guiding member 2 may be employed to penetrate the elastomer 3, thereby passing the wire 1 through the elastomer 3. The method further comprises the following steps: 3) removing the guiding member 2 to leave the wire 1 in the first hole 30 formed in the elastomer 3 alone; and 4) bending both ends of the wire 1 to abut against the a top and a bottom surface of the elastomer 3 to form an elastic contact therebetween. Each of the wires 1 of the electrical connector manufactured by the method is in elastic contact with a corresponding electronic component due to compression of the elastomer 3 between the wire and the electronic component. In this embodiment, the electronic component is substantially a chip module.
Referring to FIG. 6, according to the present invention, the electrical connector comprises: an elastomer 3, wires 1 provided in the elastomer 3, and at least two positioning structures 4 for mating with a corresponding electronic component. In this connector, the elastomer 3 is provided with holes 30 for accommodating the wires 1. Alternatively, the wires can directly penetrate the elastomer and are then arranged in the elastomer. Each wire 1 in the elastomer 3 is bent and comprises a stationary portion 10, and a upper and a lower contact portion both bent at a top and a bottom end of the stationary portion 10 respectively. The lower contact portion 12 is in contact with the corresponding circuit board 6. Additionally, each corner of the elastomer 3 is provided with a second hole 31 for positioning the positioning structure 4 with the elastomer 3. The positioning structure 4 is also provided with a plug 40 for limiting a height of the corresponding electronic component. Alternatively, the plug 40 can be provided on the electrical connector, instead of the positioning structure, to keep the connector from being damaged due to excessive forces being applied to the corresponding electronic component. When connected with the two corresponding electronic components, the positioning structure 4 is fixed with the two components and provides electrical connection therebetween.
Referring to FIG. 7, another embodiment different from the first one is disclosed. A peripheral of one side of the elastomer 3 is provided with a positioning element 32 for positioning a corresponding electronic component. A space 33 enclosed by the positioning element 32 is formed to accommodate a chip module, and spacers 34 are provided in the space 33 to prevent the chip module 5 experiencing excessive forces. Meanwhile, the other side of the elastomer is provided with posts 7 matching with and holding the circuit board 6. Thus, the chip module is electrical ally connected with the circuit board with the aid of the wires.
The electrical connector made by passing the wires into the elastomer, has the following merits: it has a simple configuration, the process is easy, it is cheap and has a higher processing efficiency.
Although the present invention has been described with reference to the foregoing preferred embodiment, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications may occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
