FIELD

The present invention relates to an electrical connector, and particularly to a Peripheral Component Interconnect Express (PCI-E) electrical connector used for insertion of an electronic card.

BACKGROUND

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.

Currently, the industry provides an electrical connector, which is used for insertion of an electronic card. The electrical connector includes: an insulating body, multiple terminals accommodated in the insulating body, a metal member provided on the insulating body, and a retainer provided at an elongated end of the insulating body. The insulating body includes two side walls extending along an elongated direction thereof, and two end walls connecting the two side walls, and the two side walls and the two end walls surroundingly form an insertion slot, which is used for the electronic card to insert therein along a mating direction. The metal member covers the insulating body to strengthen the strength of the insulating body. The metal member is provided with multiple through slots corresponding to each of the side walls, and the through slots are in parallel to or perpendicular to the mating direction to dissipate the heat generated by the electrical connector during usage.

However, the through slots are provided in parallel to or perpendicular to the mating direction, such that the length of the through slots parallel to or perpendicular to the mating direction is too long, resulting in the through slots reducing the strength of the metal member to an excessive degree, and causing the metal member to have great deformation in the process of forming the through slots, which is not in favor of the metal member being provided on the insulating body.

Further, since the through slots are provided in parallel to or perpendicular to the mating direction, the heat generated by the electrical connector during usage is dissipated only in a single direction, thereby affecting the normal usage of the electrical connector due to untimely heat dissipation thereof.

Therefore, a heretofore unaddressed need to design a new electrical connector exists in the art to address the aforementioned deficiencies and inadequacies.

An upper end of each of the first edges 321 is located closer to the retainer 5 relative to a lower end of each of the first edges 321 in the X direction (referring to FIG. 13 and FIG. 14). The second edge 322 is located closer to the retainer 5 relative to the third edge 323. In other embodiments, the second edge 322 may be provided to be located farther away from the retainer 5 relative to the third edge 323. The receiving slot 115 and the accommodating slot 117 are in communication with each other in the X direction, and the metal member 3 and the reinforcing member 4 are integrally provided.

To sum up, the electrical connector according to certain embodiments of the present invention has the following beneficial effects:

(1) In comparison with the structures of the through slots 32 commonly used in the industry, i.e., the structures of the through slots 32 provided in parallel to or perpendicular to the Z direction, and with the premise that the quantity and area of the through slots 32 are the same, the through slots 32 being provided obliquely may effectively reduce the length of the through slots 32 parallel to or perpendicular to the Z direction, such that the metal member 3 maintains a stronger strength and does not easily deform, facilitating the metal member 3 to be provided on the body 1. Further, since the through slots 32 are provided obliquely, in the process of heat dissipating through the oblique through slots 32, the flow disturbing effect may easily occur, and the heat is diffused outward, such that the heat dissipation speed and flow rate significantly increase, facilitating timely heat dissipation and ensuring the normal use of the electrical connector 100.

(2) The heat generated by the electrical connector 100 during usage is mainly concentrated in the locations near the retainer 5. The through slots 32 are provided at the locations near the retainer 5, and with the premise that the strength of the metal member 3 is ensured, it is possible to timely dissipate the heat in a directed manner.

(3) The two first edges 321 are in parallel to each other and are provided obliquely relative to the Z direction, thus effectively reducing the length of each of the two first edges 321 parallel to or perpendicular to the Z direction, such that the metal member 3 maintains a stronger strength. Further, in the process of heat dissipating through the two oblique first edges 321, the flow disturbing effect may easily occur, and the heat is diffused outward, such that the heat dissipation speed and flow rate significantly increase.

(4) The first wall 1141 and the first edges 321 are in parallel to each other, and the first edges 321 are provided obliquely relative to the Z direction, such that in the process of heat dissipating through the oblique first wall 1141, the flow disturbing effect may further occur, and the heat is diffused outward, such that the heat dissipation speed and flow rate further significantly increase.

(5) The receiving slot 115 runs downward through the first wall 1141, the second wall 1142 and the third wall 1143 respectively, and does not run outward through the corresponding side wall 11. The metal member 3 is accommodated in the receiving slot 115 and is in interference fit with the receiving slot 115, such that the corresponding side wall 11 covers a front end, a rear end and a bottom portion of the metal member 3, thus reliably fixing the metal member 3 to the body 1.
