Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector for connecting a wafer module to a printed circuit board.

An electrical connector associated with the present invention for electrically connecting a chip module to a circuit board as disclosed in U.S. Patent No. 6,083,313. The electrical connector includes a body, a plurality of sidewalls extending from the periphery of the body portion, and a plurality of terminals disposed on the body. The terminal includes a holding portion held in the body and a tilting elastic arm extending from the upper surface of the body. The tilting elastic arm of the terminal covers the adjacent terminal in the vertical direction. When the wafer module is placed downward, the terminal is deformed by being pressed and the adjacent inclined elastic arms are moved toward each other.

However, the inclined resilient arms of adjacent terminals are close to each other, and the risk of shorting between the terminals is also increased, especially when the wafer module is subjected to external device pressure.

In view of this, it is indeed necessary to provide an improved electrical connector that overcomes the deficiencies of the aforementioned electrical connectors.

The purpose of this creation is to provide an electrical connector that avoids shorting of the conductive terminals.

In order to achieve the foregoing objectives, the present invention adopts the following technical solutions: an electrical connector includes: an insulative housing; a cover body disposed on the insulative housing, having opposite upper and lower surfaces; and conductive terminals including components And a resilient arm extending upwardly from the body portion and penetrating the cover body in the main body portion of the insulating body, the elastic arm having a contact portion extending from an upper surface of the cover body.

In order to achieve the foregoing object, the present invention can also adopt the following technical solutions: an electrical connector includes: an insulative housing; a cover body disposed on the insulative housing, the opposite surface and the lower surface and the plurality of penetrating covers are disposed opposite to each other a through hole of the upper surface and the lower surface; the conductive terminal comprises a main body portion disposed in the insulating body, an elastic arm extending upward from the main body portion and penetrating through the cover body, and the through hole can be restricted by the elastic arm The elastic arms caused by the movement in the horizontal direction and the vertical direction are excessively depressed.

In order to achieve the foregoing object, the present invention can also adopt the following technical solution: an electrical connector, comprising: an insulative housing, which is provided with an accommodating space; and a cover body that moves up and down in the accommodating space, and is provided with a relative arrangement a surface and a lower surface and a plurality of through holes penetrating through the upper surface and the lower surface of the cover; the conductive terminal is received in the through hole, and the conductive terminal comprises a body portion disposed in the insulating body and extending upward from the body portion The arm is inclined in a direction in which the through hole is inclined during the downward movement of the cover.

Compared with the prior art, the cover of the present electrical connector can move up and down in the accommodating space, and the contact portion extends out of the through hole. During the downward movement of the cover body, the through hole can be restricted by the elastic arm at the level The elastic arms caused by the movement in the direction and the vertical direction are excessively depressed, thereby preventing a short circuit occurring between the conductive terminals due to mutual overlap.

Referring to the first to sixth figures, the electrical connector 1 is used to electrically connect a chip module (not shown) and a printed circuit board (not shown). The electrical connector 1 includes an insulative housing 2, a plurality of electrically conductive terminals 3 disposed on the insulative housing 2, and a cover 4 disposed on the insulative housing 2.

Referring to the second and sixth figures, the insulative housing 2 includes an accommodation space (not labeled). The insulative housing 2 further includes a base body 20 and a plurality of side walls 21 extending upward from the base body 20. The base body 20 and the side wall 21 form a receiving space (not numbered) for accommodating the cover body 4. The base body 20 is provided with a plurality of receiving slots 22 for holding the conductive terminals 3. The conductive terminal 3 includes a main body portion 30, an elastic arm 31 extending upward from the main body portion 30 and inclined, and a welded portion 32 extending downward from the main body portion 30. The bottom surface of the insulative housing 2 is recessed with a receiving groove 23 communicating with the receiving groove 22. The solder ball 5 is partially housed in the accommodating groove 23 and the soldering portion 32 is extended into the accommodating groove 23 to hold the solder ball 5.

The cover body 4 is movable up and down in the accommodating space, and the cover body 4 includes a plurality of through holes 40 disposed obliquely. The elastic arms 31 of the conductive terminals 3 are received in the through holes 40 and extend along the through holes 40. The elastic arm 31 has a contact portion 310, and the contact portion 310 extends from the upper surface 41 of the cover 4 to engage with the wafer module. The through hole 40 is substantially in the shape of a slanted cone, and the diameter of the opening communicating with the upper surface 41 is smaller than the diameter of the opening communicating the lower surface 42. Please refer to the fifth to sixth figures. Before the cover 4 is installed in the insulative housing 2, the conductive terminal 3 is inserted into the insulative housing 2, and the elastic arm 31 of the conductive terminal 3 has a linear structure and is vertically arranged. . When the cover body 4 moves toward the insulative housing 2, the elastic arm 31 of the wire-shaped conductive terminal 3 abuts against the inner surface of the inclined through hole 40, and the elastic arm 31 will follow the inclined structure of the inner surface of the through hole 40, and further The elastic arm 31 is tilted. The closer the cover 4 is to the insulative housing 2, the greater the angle at which the resilient arms 31 are inclined. After the assembly is completed, the conductive terminal 3 is bent into a state as shown in the sixth figure, and the elastic arm 31 abuts against the inner surface of the through hole 40 in a free state in which no external force acts.

The through hole 40 can restrict the elastic arm 31 from being excessively depressed by the movement of the elastic arm 31 in the horizontal direction and the vertical direction, and can avoid a short circuit between the adjacent conductive terminals 3. In addition, when the wafer mold is assembled on the electrical connector 1, the elastic arm 31 of the conductive terminal 3 is depressed and moved downward, but the inclined through hole 40 is provided to restrict the elastic arm 31 from moving further downward. The elastic arm 31 is exposed to the upper surface 41 of the cover 4 to facilitate electrical contact between the wafer module and the conductive terminal 3.

In summary, the creation complies with the new patent requirements and proposes a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the foregoing embodiments, and equivalent modifications or changes made by those skilled in the art in accordance with the spirit of the present invention should be It is covered by the following patent application.
