This application claims the benefit of the filing date under 35 U.S.C. ยง 119(a)-(d) of Chinese Patent Application No. 202020185670.6, filed on Feb. 19, 2020.
The present disclosure relates to an electrical connector and, more particularly, to a socket connector electrically connected with a plate-type plug.
In an existing socket connector electrically connected with a plate-type plug, the socket connector has a locking protrusion to be matched with a locking hole in the plate-type plug. When the plate-type plug is inserted into the socket connector and connected with the socket connector, the locking protrusion is inserted into the locking hole of the plate-type plug in a direction perpendicular to the insertion direction, thereby preventing the plate-type plug from being detached from the socket connector.
Because the locking protrusion is formed by a stamping process, however, an end of the locking protrusion in contact with the plate-type plug is disconnected from a base for forming the locking protrusion. A created locking force is insufficient during pulling out the plate-type plug, or can result in damage to the locking protrusion.
An electrical connector includes a main body portion having a receiving passage adapted to receive a plate-type plug inserted in an insertion direction, and a locking protrusion formed on the main body portion and protruding toward the receiving passage. The locking protrusion has a connection portion adapted to connect a top portion of the locking protrusion with the main body portion downstream in the insertion direction.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
The technical solution of the disclosure will be described hereinafter in further detail with reference to the following embodiments, taken in conjunction with the accompanying drawings. In the description, the same or similar reference numerals indicate the same or similar parts. The description of the embodiments of the disclosure hereinafter with reference to the accompanying drawings is intended to explain the general inventive concept of the disclosure and should not be construed as a limitation on the disclosure.
In addition, in the following detailed description, for the sake of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may also be practiced without these specific details. In other instances, well-known structures and devices are illustrated schematically in order to simplify the drawing.
An electrical connector 100 according to an embodiment, as shown in
During insertion of the plate-type plug 200 into the receiving passage 10 of the electrical connector 100, as shown in
Because the connection portion 21, shown in
In an embodiment, as shown in
The locking protrusion 2, as shown in
As shown in
It should be understood that the locking protrusion 2 may be formed by a stamping process after the two side portions 25 of the locking protrusion 2 are firstly cut out on the flat bottom portion 11 of the main body 1. Thereafter, the cantilever 12 is formed on the bottom portion 11 by shearing and stamping processes.
In an embodiment, as shown in
As shown in
In an exemplary embodiment of the disclosure, as shown in
The plate-type plug 200 may be electrically connected to another cable so as to realize a quick electrical connection of two cables. In an alternative embodiment of the disclosure, the plate-type plug 200 may be connected with a plurality of cables.
In the electrical connector 100, because the connection portion 21 is configured to connect the top portion 23 of the locking protrusion 2 and the main body portion 1 downstream in the insertion direction D, the locking force of the locking protrusion 2 is increased. The electrical connector 100 may be formed by a single metal plate such as a copper sheet through machining processes such as shearing, stamping, and bending process, and thus has a simple and compact structure.
In a case where the metal plate has a thickness of about 0.25 mm, the locking force of the locking protrusion 2 of the electrical connector 100 is 132 N after a simulated mechanical analysis is made to the electrical connector 100. Compared with the electrical connector with the locking protrusion in a suspended state on the downstream side, the locking force of the locking protrusion 2 of the electrical connector 100 according to the embodiments of the disclosure can be increased by 93.9%.
In a case where the metal plate has a thickness of about 0.25 mm, the locking force of the locking protrusion 2 of the electrical connector 100 is 111 N after a plurality of mechanical tests are made to the electrical connector 100 according to the embodiments of the disclosure. Compared with the electrical connector with the locking protrusion in a suspended state on the downstream side, the average locking force of the locking protrusion 2 of the electrical connector 100 of the embodiments of the disclosure can be increased by 88%.
It should be appreciated by those skilled in this art that the above embodiments are intended to be illustrative, and many modifications may be made to the above embodiments by those skilled in this art. Further, various structures described in various embodiments may be freely combined with each other without conflicting in configuration or principle. Although the disclosure has been described hereinbefore in detail with reference to the attached drawings, it should be appreciated that the disclosed embodiments in the attached drawings are intended to illustrate the embodiments of the disclosure by way of example, and should not be construed as limitation to the disclosure. Although a few embodiments of the general inventive concept of the disclosure have been shown and described, it would be appreciated by those skilled in the art that changes or modification may be made to these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in claims and their equivalents.
