Definitions
- the present invention relates to an electrical connector, and in particular to an electrical connector for electrically connecting a chip module to a circuit board.
- the Chinese patent CN200720125631.1 discloses an electrical connector, which includes an insulating body provided with a plurality of terminal accommodating grooves, and a plurality of conductive terminals accommodated in the terminal accommodating grooves.
- the terminal accommodating grooves are arranged inmultiple rows, and each two adjacent rows of the terminal accommodating grooves are arranged right opposite to each other in a front-rear direction.
- Each conductive terminal includes a base retained in the corresponding terminal accommodating groove and a pair of elastic arms obliquely extending upward from the top and bottom of the base respectively.
- a cantilever-shaped rib portion extends from the middle of each elastic arm. When the elastic arms are completely pressed down by a chip module, the two rib portions contact each other, so as to provide a short electrical path between the chip module and a printed circuit board.
- the electrical connector at least has the following disadvantage. Since the terminal accommodating grooves are arranged in multiple rows and each two adjacent rows of the terminal accommodating grooves are arranged opposite to each other in the front-rear direction, each two adjacent rows of the conductive terminals almost completely coincide in the front-rear direction, causing inevitable crosstalk between two adjacent rows of conductive terminals. As a result, the signal transmission quality of the electrical connector is reduced, and the electrical connector cannot provide faster and stable signal transmission, thus causing a usage bottleneck of the electrical connector.
- An objective of the present invention is to provide an electrical connector capable of avoiding crosstalk between terminals and reducing the impedance of the terminals.
- the present invention adopts the following technical solutions:
- an electrical connector configured to electrically connect a chip module to a circuit board, including: a body, configured to upward support the chip module, wherein the body is provided with a plurality of accommodating holes arranged in a plurality of rows, and each two adjacent rows of the accommodating holes are staggeredly arranged in a front-rear direction; and a plurality of terminals, respectively accommodated in the accommodating holes correspondingly, where for each two adjacent rows, one terminal in one of the two adjacent rows of the terminals intersects with a corresponding one terminal in the other one of the two adjacent rows of the terminals in a left-right direction to form an intersection area, and each of the terminals comprising a base, an upper elastic arm formed by extending upward from the base and configured to upward abut the chip module, and a lower elastic arm formed by extending downward from the base and configured to be downward conductively connected with the circuit board; wherein when the chip module presses the upper elastic arm downward, the upper elastic arm and the lower elastic arm abut each other at an abutting position
- one of the terminals respectively intersects with two adjacent terminals in an adjacent row so as to form two intersection areas.
- each of the terminals further comprises one remaining area excluding the intersection area, wherein the remaining area is larger than the intersection area.
- the upper elastic arm comprises an upper extending portion extending upward obliquely from the base, an upper contact portion bending and extending upward from the upper extending portion and configured to upward abut against the chip module, and an upper abutting portion extending downward obliquely from the upper contact portion; and the lower elastic arm comprises a lower extending portion extending downward obliquely from the base, a lower contact portion bending and extending downward from the lower extending portion and configured to be downward conductively connected with the circuit board, a connecting portion bending and extending upward from the lower contact portion, and a lower abutting portion extending upwards from the connecting portion, wherein the upper abutting portion and the lower abutting portion abut each other at the abutting position, and the abutting position is located above the intersection area.
- the base of each of the terminals intersects with the connecting portion of the terminal in an adjacent row to form the intersection area.
- the connecting portion is located at a left side of the base, and comprises a first portion bending and extending from the lower contact portion to an upper right direction, and a second portion bending and extending from the first portion to an upper left direction and connected with the lower abutting portion; wherein the upper extending portion bends and extends from the base to the upper left direction, and the lower extending portion bends and extends from the base to a lower left direction.
- an included angle between the first portion and the second portion is greater than an included angle between the upper extending portion and the lower extending portion.
- the upper abutting portion is parallel to the lower abutting portion, and an outer surface of the upper abutting portion abuts an inner surface of the lower abutting portion.
- a strip connecting portion is formed by extending upward from the lower abutting portion and configured to be connected to a strip, wherein a gap is provided between the strip connecting portion and the upper elastic arm, each of the accommodating holes has a vertical surface and an oblique surface extending upward obliquely from a top end of the vertical surface; the oblique surface and the strip connecting portion are provided opposite to each other, and the strip connecting portion is located higher than the top end of the vertical surface and lower than a top end of the oblique surface.
- a partition wall is provided between two adjacent accommodating holes in a same row, and the base and the connecting portion of one of the terminals in an adjacent row are located on two opposite sides of the partition wall.
- the electrical connector according to certain embodiments of the present invention has the following beneficial effect.
- each two adjacent rows of the accommodating holes are arranged staggeredly in a front-rear direction, so that for each two adjacent rows of terminals, one terminal in one of the two adjacent rows of the terminals intersects with a corresponding one terminal in the other one of the two adjacent rows of the terminals in the left-right direction to form the intersection areas.
- the chip module presses each upper elastic arm downward, the upper elastic arm abuts the corresponding lower elastic arm, and multiple conductive paths of each terminal can be formed so as to reduce the impedance of the terminal.
- the abutting position is located above or below the intersection area, thereby reducing the size of each intersection area, effectively reducing the crosstalk effect between each two adjacent rows of the terminals, and improving the signal transmission quality of the electrical connector, so that the electrical connector can be used for transmitting signals at a higher rate.
- FIG. 1 is a perspective view of an electrical connector according to a first embodiment of the present invention before a chip module is pressed downwards;
- FIG. 2 is a top view of FIG. 1 ;
- FIG. 3 is a sectional view of FIG. 2 along an A-A direction;
- FIG. 4 is a plan view obtained after the chip module is pressed downwards in FIG. 3 ;
- FIG. 5 is an enlarged view of a part a in FIG. 4 ;
- FIG. 6 is a plan view of an electrical connector according to a second embodiment of the present invention after a chip module is pressed downwards.
- relative terms such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The exemplary term “lower”, can therefore, encompasses both an orientation of “lower” and “upper,” depending of the particular orientation of the figure.
- “around”, “about” or “approximately” shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range. Numerical quantities given herein are approximate, meaning that the term “around”, “about” or “approximately” can be inferred if not expressly stated.

Description
- This application claims priority to and the benefit of, pursuant to 35 U.S.C. § 119(e), U.S. provisional patent application Ser. No. 62/445,396, filed Jan. 12, 2017. This application also claims priority to and benefit of, under 35 U.S.C. § 119(a), Patent Application No. 201710654596.0 filed in P.R. China on Aug. 3, 2017. The entire contents of the above-identified applications are incorporated herein in their entireties by reference.
- Some references, which may include patents, patent applications and various publications, are cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein. All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference were individually incorporated by reference.
- The present invention relates to an electrical connector, and in particular to an electrical connector for electrically connecting a chip module to a circuit board.
- The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
- The Chinese patent CN200720125631.1 discloses an electrical connector, which includes an insulating body provided with a plurality of terminal accommodating grooves, and a plurality of conductive terminals accommodated in the terminal accommodating grooves. The terminal accommodating grooves are arranged inmultiple rows, and each two adjacent rows of the terminal accommodating grooves are arranged right opposite to each other in a front-rear direction. Each conductive terminal includes a base retained in the corresponding terminal accommodating groove and a pair of elastic arms obliquely extending upward from the top and bottom of the base respectively. A cantilever-shaped rib portion extends from the middle of each elastic arm. When the elastic arms are completely pressed down by a chip module, the two rib portions contact each other, so as to provide a short electrical path between the chip module and a printed circuit board.
- However, the electrical connector at least has the following disadvantage. Since the terminal accommodating grooves are arranged in multiple rows and each two adjacent rows of the terminal accommodating grooves are arranged opposite to each other in the front-rear direction, each two adjacent rows of the conductive terminals almost completely coincide in the front-rear direction, causing inevitable crosstalk between two adjacent rows of conductive terminals. As a result, the signal transmission quality of the electrical connector is reduced, and the electrical connector cannot provide faster and stable signal transmission, thus causing a usage bottleneck of the electrical connector.
- Therefore, a heretofore unaddressed need to design a novel electrical connector exists in the art to address the aforementioned deficiencies and inadequacies.
- An objective of the present invention is to provide an electrical connector capable of avoiding crosstalk between terminals and reducing the impedance of the terminals.
- To achieve the foregoing objective, the present invention adopts the following technical solutions:
- an electrical connector, configured to electrically connect a chip module to a circuit board, including: a body, configured to upward support the chip module, wherein the body is provided with a plurality of accommodating holes arranged in a plurality of rows, and each two adjacent rows of the accommodating holes are staggeredly arranged in a front-rear direction; and a plurality of terminals, respectively accommodated in the accommodating holes correspondingly, where for each two adjacent rows, one terminal in one of the two adjacent rows of the terminals intersects with a corresponding one terminal in the other one of the two adjacent rows of the terminals in a left-right direction to form an intersection area, and each of the terminals comprising a base, an upper elastic arm formed by extending upward from the base and configured to upward abut the chip module, and a lower elastic arm formed by extending downward from the base and configured to be downward conductively connected with the circuit board; wherein when the chip module presses the upper elastic arm downward, the upper elastic arm and the lower elastic arm abut each other at an abutting position located above or below the intersection area.
- In certain embodiments, one of the terminals respectively intersects with two adjacent terminals in an adjacent row so as to form two intersection areas.
- In certain embodiments, each of the terminals further comprises one remaining area excluding the intersection area, wherein the remaining area is larger than the intersection area.
- In certain embodiments, the upper elastic arm comprises an upper extending portion extending upward obliquely from the base, an upper contact portion bending and extending upward from the upper extending portion and configured to upward abut against the chip module, and an upper abutting portion extending downward obliquely from the upper contact portion; and the lower elastic arm comprises a lower extending portion extending downward obliquely from the base, a lower contact portion bending and extending downward from the lower extending portion and configured to be downward conductively connected with the circuit board, a connecting portion bending and extending upward from the lower contact portion, and a lower abutting portion extending upwards from the connecting portion, wherein the upper abutting portion and the lower abutting portion abut each other at the abutting position, and the abutting position is located above the intersection area.
- In certain embodiments, the base of each of the terminals intersects with the connecting portion of the terminal in an adjacent row to form the intersection area.
- In certain embodiments, the connecting portion is located at a left side of the base, and comprises a first portion bending and extending from the lower contact portion to an upper right direction, and a second portion bending and extending from the first portion to an upper left direction and connected with the lower abutting portion; wherein the upper extending portion bends and extends from the base to the upper left direction, and the lower extending portion bends and extends from the base to a lower left direction.
- In certain embodiments, an included angle between the first portion and the second portion is greater than an included angle between the upper extending portion and the lower extending portion.
- In certain embodiments, the upper abutting portion is parallel to the lower abutting portion, and an outer surface of the upper abutting portion abuts an inner surface of the lower abutting portion.
- In certain embodiments, a strip connecting portion is formed by extending upward from the lower abutting portion and configured to be connected to a strip, wherein a gap is provided between the strip connecting portion and the upper elastic arm, each of the accommodating holes has a vertical surface and an oblique surface extending upward obliquely from a top end of the vertical surface; the oblique surface and the strip connecting portion are provided opposite to each other, and the strip connecting portion is located higher than the top end of the vertical surface and lower than a top end of the oblique surface.
- In certain embodiments, a partition wall is provided between two adjacent accommodating holes in a same row, and the base and the connecting portion of one of the terminals in an adjacent row are located on two opposite sides of the partition wall.
- Compared with the related art, the electrical connector according to certain embodiments of the present invention has the following beneficial effect.
- In the present invention, each two adjacent rows of the accommodating holes are arranged staggeredly in a front-rear direction, so that for each two adjacent rows of terminals, one terminal in one of the two adjacent rows of the terminals intersects with a corresponding one terminal in the other one of the two adjacent rows of the terminals in the left-right direction to form the intersection areas. When the chip module presses each upper elastic arm downward, the upper elastic arm abuts the corresponding lower elastic arm, and multiple conductive paths of each terminal can be formed so as to reduce the impedance of the terminal.
