The present invention relates to an electrical connector, and particularly to an electrical connector that effectively reduces signal transmission loss.
An electrical connector in the prior art (as shown in
To solve the foregoing problem existing in the electrical connector, and improve the signal transmission quality of the electrical connector, a general choice is to remove the guide portion 104 of the foregoing conducting terminal 10. However, after the guide portion 104 of the conducting terminal 10 is removed, during frequent insertion, because of loss of a role which the guide portion 104 plays of guiding the mating connector, the contact portion 102 easily bends, thereby damaging the conducting terminal 10.
Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.
In one aspect, the present invention is directed to an electrical connector that presses against a terminal using a mating connector, thereby improving signal transmission quality.
In one embodiment, an electrical connector for mating with a mating connector includes an insulating body and multiple terminals. The insulating body has a base and a tongue protruding forward from the base. The insulating body is provided with multiple terminal slots, and the multiple terminal slots run from the tongue backward through the base. The terminals are disposed in the terminal slots. Each of the terminals has a retaining portion retained at the base, a contact portion extending forward from one end of the retaining portion to the tongue, and an urging portion disposed between the retaining portion and the contact portion. The urging portion is higher than an upper surface of the tongue. When the electrical connector mates with the mating connector, the mating connector presses against the urging portion downward, so that the contact portion electrically contacts the mating connector.
In one embodiment, before the electrical connector mates with the mating connector, the contact portion is located in the terminal slot.
In one embodiment, when the electrical connector mates with the mating connector, the contact portion is exposed from a lower surface of the tongue.
In one embodiment, the terminal slot vertically runs through the tongue corresponding to a position of the urging portion.
In one embodiment, a stopping portion is disposed above the terminal slot corresponding to the contact portion.
In one embodiment, the electrical connector further includes an insulating block. The multiple terminals are arranged into a row, and the insulating block and the multiple terminals are integrally injection molded.
In another aspect, the present invention is directed to an electrical connector. In one embodiment, an electrical connector for mating with a mating connector includes an insulating body and multiple terminals. The insulating body has a base and a tongue protruding forward from the base. The insulating body is provided with multiple terminal slots, and the multiple terminal slots run from the tongue backward through the base. The multiple terminals are disposed in the multiple terminal slots. Each of the terminals has a retaining portion retained at the base, a contact portion extending forward from one end of the retaining portion to the tongue, and an urging portion disposed between the retaining portion and the contact portion. The urging portion extends out of the tongue. When the electrical connector mates with the mating connector, the mating connector presses against the urging portion, so that the contact portion is exposed from the tongue and electrically contacts the mating connector.
In one embodiment, before the electrical connector mates with the mating connector, the contact portion is located in the terminal slot.
In one embodiment, a stopping portion is disposed at a position of the terminal slot corresponding to the contact portion.
In one embodiment, the terminal slot runs through the tongue corresponding to a position of the urging portion.
In a further aspect, the present invention is directed to an electrical connector. In one embodiment, an electrical connector for mating with a mating connector includes an insulating body and multiple terminals disposed in the insulating body. Each of the terminals has an urging portion and a contact portion extending forward from the urging portion. The mating connector includes an insulating case, and the insulating case has a mating portion. Multiple conducting terminals are disposed at the insulating case. When the electrical connector mates with the mating connector, the mating portion presses against the urging portion downward, so that the contact portion electrically contacts the conducting terminal.
In one embodiment, the insulating body has a base and a tongue protruding forward from the base, the insulating body is provided with multiple terminal slots, the multiple terminal slots run from the tongue backward through the base, and the multiple terminals are correspondingly disposed at the multiple terminal slots.
In one embodiment, the urging portion is higher than an upper surface of the tongue, and the contact portion is located in the terminal slot.
In one embodiment, the terminal slot vertically runs through the tongue corresponding to a position of the urging portion.
In one embodiment, a stopping portion is disposed at a position of the terminal slot corresponding to the contact portion.
Compared with the related art, certain embodiments of the present invention have the following beneficial advantages.
The urging portion is higher than the upper surface of the tongue. When the electrical connector mates with the mating connector, the mating connector presses against the urging portion downward, so that the contact portion electrically contacts the mating connector. Thus, it is not required to additionally dispose a structure at the front end of the contact portion to guide insertion of the mating connector, and the length of the terminal is shortened, thereby reducing the signal transmission loss to improve the signal transmission quality of the electrical connector. Moreover, the mating connector presses against the urging portion, so that the contact portion electrically contacts the mating connector, thereby protecting the contact portion in the insertion process, and preventing the terminal from being damaged.
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 invention and together with the written description, serve to explain the principles of the invention. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
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.

In summary, the electrical connector according to certain embodiments of the present invention, among other things, has the following beneficial advantages.
(1) The urging portion 204 is higher than the upper surface of the tongue 12. When the electrical connector mates with the mating connector 200, the top wall of the mating portion 40 presses against the urging portion 204 downward, so that the contact portion 202 electrically contacts the conducting terminal 50. Thus, it is not required to additionally dispose a structure at the front end of the contact portion 202 to guide insertion of the mating connector 200, and the length of the terminal 20 is shortened, thereby reducing the signal transmission loss to improve the signal transmission quality of the electrical connector 100. Moreover, the mating portion 40 presses against the urging portion 204, so that the contact portion 202 electrically contacts the conducting terminal 50, thereby protecting the contact portion 202 in the insertion process, and preventing the terminal 20 from being damaged.
(2) The contact portion 202 is located in the terminal slot 13, so that the contact portion 202 is prevented from external environmental pollution.
(3) The terminal slot 13 vertically runs through the tongue 12 corresponding to the position of the urging portion 204, which helps the electrical connector 100 perform heat dissipation.
