BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electrical connector and method of making the same, and more particularly to an electrical connector using insert-molded method to position conductive contacts and grounding terminals.

2. Description of Related Art

Chinese patent No. 201498709 issued to Chang on Jun. 2, 2010 discloses a conventional electrical connector for electrically connecting an IC package with a substrate. The electrical connector includes a base with a number of conductive contacts and a number of grounding terminals received therein. The base is made of copper or similar conductive materials. There is an insulation member locating around the conductive contact to insulate the conductive contact and the base. The grounding terminals contact with the base to establish an electrical path. Due to the base is made of copper and also need to manufacture a number of holes to receive the conductive contacts and the grounding terminals, thus made the electrical connector high-cost.

Hence, it is desirable to provide an improved electrical connector to overcome the aforementioned disadvantages.

SUMMARY OF THE INVENTION

Accordingly, an object of the present invention is to provide an electrical connector using insert-molded method to position conductive contacts and grounding terminals.

According to one aspect of the present invention, an electrical connector for electrically connecting an IC package with a substrate comprises a number of conductive contacts, a number of grounding terminals, an insulative member locates around the conductive contacts with insert-molded method and an electrical member locates around the insulative member and the grounding terminals with insert-molded method. The insulative member is made of insulation materials. The electrical member is made of electrical resin. The conductive contacts are insulated from the electrical member and the grounding terminals are electrically connected with the electrical member.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 4 to 5illustrate an electrical connector100in accordance to a preferred embodiment of the present invention, the electrical connector100is used for electrically connecting an IC package (not labeled) with a substrate (not labeled). The electrical connector100comprises a number of conductive contacts4, a number of grounding terminals5, an insulative member32located around the conductive contacts4, an electrical member1made of electrical resin located around the insulative member32and the grounding terminals5. The electrical connector100also comprises an upper insulative member2locates on upper end of the electrical member1and a lower insulative member31locates on lower end of the electrical member1. The electrical resin is made of liquid crystal polyester.

Referring toFIGS. 1-2andFIG. 5, the conductive contact4is configured to a cylinder type and comprises a body portion40, an upper end41extending upwardly from the body portion40and a lower end42extending downwardly from the body portion40. The cross-sectional area of the body portion40is larger than that of the upper end41and that of the lower end42. The free end of the upper end41defines an upper contact portion410and the free end of the lower end defines a lower contact portion420.

The upper contact portion410extends beyond the upper insulative member2to electrically connecting with the IC package. The lower contact portion420extends beyond the lower insulative member31to electrically connecting with the substrate. The height of the insulative member32equals to that of the body portion40of the conductive contact4and that of the electrical member1. The conductive contacts4are insulated from the electrical member1. The grounding terminals5have a same structure with the conductive contacts4and are electrically connected with the electrical member1.

Referring toFIGS. 1-4, the electrical connector100is made by insert-molded method. The steps are as following: firstly, providing a number of conductive contacts4and a number of grounding terminals5; secondly, providing an insulative member32and a lower insulative member31made of insulation materials insert-molded with the conductive contacts4and the grounding terminals5; thirdly, providing an electrical member1made of electrical resin located around the insulative member32and the grounding terminals5with insert-molded method, the conductive contacts4are insulated from the electrical member1and the grounding terminals5are electrically connected with the electrical member1; then, providing an upper insulative member2made of insulation materials insert-molded with the conductive contacts4and the grounding terminals5. The electrical connector100is easy to make and can save the cost.
