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 particularly to an electrical connector having a conductive terminal capable of being compressed in two directions.
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.
A conventional electrical connector is used to electrically connect a chip module with a circuit board, and includes a body and multiple conductive terminals assembled on the body. Each conductive terminal has a base, and the base is provided with a barb protrusion in interference fit with the body to fix the conductive terminal to the body. An upper elastic arm is formed by bending and extending upward from an upper end of the base. The upper elastic arm can be elastically deformed to upward abut the chip module. A lower elastic arm is formed by bending and extending downward from a lower end of the base. The lower elastic arm can be elastically deformed to downward abut the circuit board. However, to ensure the elasticity of the upper elastic arms and the lower elastic arms so as to achieve good contact between the upper elastic arms and the chip module and good contact between the lower elastic arms and the circuit board, the upper elastic arms and the lower elastic arms need to have relatively great lengths. Thus, the conductive terminals have relatively great heights, which is unfavorable for ultra-thinning of the electrical connector.
Therefore, a heretofore unaddressed need to design an improved electrical connector exists in the art to address the aforementioned deficiencies and inadequacies.
The present invention is directed to an electrical connector having terminals with a reduced height.
To achieve the foregoing objective, the present invention adopts the following technical solutions.

In certain embodiments, an upper protruding portion is formed by extending upward from the position limiting protruding block, a lower protruding portion is formed by extending downward from the position limiting protruding block, the upper protruding portion is located behind the upper position limiting portion, and the lower protruding portion is located behind the lower position limiting portion, so as to limit the flat plate portion from moving backward.
In certain embodiments, the conductive terminal has two lower position limiting portions extending from two opposite inner sides of the flat plate portion, and a distance between the two lower position limiting portions is less than a width of the position limiting protruding block.
In certain embodiments, each of the conductive terminals further has a strip connecting portion protruding and extending from an outer side of the flat plate portion to be connected to a strip, the body has a plurality of positioning slots recessed downward from an upper surface of the body, the strip connecting portion of each of the conductive terminals is accommodated in one of the positioning slots, and each of the positioning slots has an inner wall located behind the corresponding strip connecting portion to limit the corresponding strip connecting portion from moving backward.
In certain embodiments, the upper elastic arm forms two upper branches at two opposite sides of the through slot, an upper connecting portion connects the two upper branches, the upper contact portion protrudes upward from an upper surface of the upper connecting portion, a width of the upper contact portion is less than a width of the upper connecting portion, and a first interval exists between the upper contact portion and each of a left side edge and a right side edge of the upper connecting portion; and the lower elastic arm forms two lower branches at the two opposite sides of the through slot, a lower connecting portion connects the two lower branches, the lower contact portion protrudes downward from a lower surface of the lower connecting portion, a width of the lower contact portion is less than a width of the lower connecting portion, and a second interval exists between the lower contact portion and each of a left side edge and a right side edge of the lower connecting portion.
In certain embodiments, the upper elastic arm forms two upper branches at two opposite sides of the through slot, an upper connecting portion connects the two upper branches, the upper contact portion is formed by extending backward from the upper connecting portion, and a width of the upper contact portion is less than a width of the through slot; and the lower elastic arm forms two lower branches at the two opposite sides of the through slot, a lower connecting portion connects the two lower branches, the lower contact portion is formed by extending backward from the lower connecting portion, and a width of the lower contact portion is less than the width of the through slot. In certain embodiments, the upper position limiting portion and the lower position limiting portion protrude from an outer side of the flat plate portion, each of the accommodating holes is provided with a position limiting protruding block, the upper position limiting surface is provided on an upper surface of the position limiting protruding block, the lower position limiting surface is provided on a lower surface of the position limiting protruding block, and a width of the through slot is greater than a width of an overlapping portion of the position limiting protruding block and the lower position limiting portion in a vertical direction.
In certain embodiments, the upper elastic arm comprises an upper base bending backward from the flat plate portion and then extending horizontally, and an upper oblique portion extending upward and backward obliquely from the upper base, the upper contact portion is provided at a free tail end of the upper oblique portion, and the through slot extends to the upper base but does not reach the upper oblique portion.
In certain embodiments, each of the conductive terminals further has a strip connecting portion configured to be connected to a strip, the strip connecting portion is located above the upper position limiting portion, and an upper end of the strip connecting portion is higher than an upper end of the upper base.
Compared with the related art, certain embodiments of the present invention have the following beneficial effects. The flat plate portions of the conductive terminals are vertically movably limited in the accommodating holes, and in each conductive terminal, the through slot extends from the upper elastic arm through the flat plate portion to the lower elastic arm, such that the flat plate portions of the conductive terminals are elastic. That is, each of the conductive terminals is elastic through its entire length. Therefore, compared with the related art, the electrical connector can shorten the upper elastic arms and the lower elastic arms of the conductive terminals when the same elastic force is provided, thus reducing the heights of the conductive terminals, and facilitating ultra-thinning of the electrical connector. Further, in each conductive terminal, the through slot extends from the upper elastic arm through the flat plate portion to the lower elastic arm, such that the width of the flat plate portion is closer to the width of the upper elastic arm and the width of the lower elastic arm (relative to the situation where the through slot runs through the upper elastic arm and the lower elastic arm, but does not run through the flat plate portion), such that the impedance of each conductive terminal from the upper elastic arm through the flat plate portion to the lower elastic arm is relatively steady, which is conductive to improving high frequency. In addition, since the through slot can enhance the elasticity of the flat plate portion, in a process of downward inserting each conductive terminal into the corresponding accommodating hole, the lower position limiting portion provided on the flat plate portion does not damage the body easily.
These and other aspects of the present invention will become apparent from the following description of the preferred embodiment taken in conjunction with the following drawings, although variations and modifications therein may be effected without departing from the spirit and scope of the novel concepts of the disclosure.
The accompanying drawings illustrate one or more embodiments of the disclosure and together with the written description, serve to explain the principles of the disclosure. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment, and wherein:
The present invention is more particularly described in the following examples that are intended as illustrative only since numerous modifications and variations therein will be apparent to those skilled in the art. Various embodiments of the invention are now described in detail. Referring to the drawings, like numbers indicate like components throughout the views. As used in the description herein and throughout the claims that follow, the meaning of “a”, “an”, and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise. Moreover, titles or subtitles may be used in the specification for the convenience of a reader, which shall have no influence on the scope of the present invention.
It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Furthermore, 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. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.
As used herein, “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.
As used herein, the terms “comprising”, “including”, “carrying”, “having”, “containing”, “involving”, and the like are to be understood to be open-ended, i.e., to mean including but not limited to.

To sum up, the electrical connector according to certain embodiments of the present invention has the following beneficial effects:
The flat plate portions 11 of the conductive terminals 1 are vertically movably limited in the accommodating holes 21, and in each conductive terminal 1, the through slot 14 extends from the upper elastic arm 12 through the flat plate portion 11 to the lower elastic arm 13, such that the flat plate portions 11 of the conductive terminals 1 are elastic. That is, each of the conductive terminals 1 is elastic through its entire length. Therefore, compared with the related art, the electrical connector 100 can shorten the upper elastic arms 12 and the lower elastic arms 13 of the conductive terminals 1 when the same elastic force is provided, thus reducing the heights of the conductive terminals 1, and facilitating ultra-thinning of the electrical connector 100. Further, in each conductive terminal 1, the through slot 14 extends from the upper elastic arm 12 through the flat plate portion 11 to the lower elastic arm 13, such that the width of the flat plate portion 11 is closer to the width of the upper elastic arm 12 and the width of the lower elastic arm 13 (relative to the situation where the through slot 14 runs through the upper elastic arm 12 and the lower elastic arm 13, but does not run through the flat plate portion 11), such that the impedance of each conductive terminal 1 from the upper elastic arm 12 through the flat plate portion 11 to the lower elastic arm 13 is relatively steady, which is conductive to improving high frequency. In addition, since the through slot 14 can enhance the elasticity of the flat plate portion 11, in a process of downward inserting each conductive terminal 1 into the corresponding accommodating hole 21, the lower position limiting portions 114 provided on the flat plate portion 11 does not damage the body 2 easily.
