This application claims the priority benefit of Taiwan patent application serial no. 106211323, filed on Aug. 1, 2017. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of the specification.
The invention is related to an electrical connector, and particularly to a receptacle electrical connector.
Electrical connector is a common electronic component of electronic devices, capable of being connected to matching electrical connectors of other electronic devices and further enabling signal and electricity transmission between two electronic devices. One of the existing electrical connectors, for example, a universal serial bus (USB) electrical connector with newly added electrical connector Type C specification, is capable of not only transmitting data at an ultra speed, 10 Gbps, but also being plugged upright or upside down due to the symmetrical port. Such electrical connector is thus commonly applied on a variety of electronic devices such as a notebook computer.
A receptacle electrical connector with USB Type C specification has a larger number of components and the components are smaller in size. For the receptacle electrical connector that is assembled via insertion, a terminal thereof can be fixed in a corresponding groove of an insulator via a barb, which requires sufficient structural thickness between two grooves, otherwise the structure between the two grooves can be easily damaged by the barb. If the structure between the two grooves is seriously damaged, improper electrical conduction may occur between adjacent terminals.
The invention provides a receptacle electrical connector provided to be installed within an electronic device to be connected with a matching plug electrical connector.
A receptacle electrical connector of the invention includes a plurality of first terminals, a plurality of second terminals, a main insulator, a secondary insulator, a shielding plate and a shielding shell. The main insulator has a plurality of first terminal grooves and a plurality of second terminal grooves. Each first terminal accommodated in a corresponding first terminal groove is fitted with the corresponding first terminal groove in interference and in face-to-face contact. Each second terminal accommodated in a corresponding second terminal groove is fitted with the corresponding second terminal groove in interference and in face-to-face contact. The secondary insulator is engaged with the main insulator to limit each first terminal in the corresponding first terminal groove, and limit each second terminal in the corresponding second terminal groove. The shielding plate is located between the first terminals and the second terminals. The shielding shell surrounds the main insulator.
In an embodiment of the invention, each first terminal has a first side protrusion. The first side protrusion protrudes toward an adjacent first terminal, and each first terminal is fitted with the corresponding first terminal groove in interference and in face-to-face contact via the corresponding first side protrusion.
In an embodiment of the invention, each first terminal has a first soldering segment, a first connecting segment and a first contacting segment. The first connecting segment connects a corresponding first soldering segment with a corresponding first contacting segment, and the first side protrusion protrudes from a corresponding first connecting segment.
In an embodiment of the invention, each second terminal has a second side protrusion. The second side protrusion protrudes toward an adjacent second terminal, and each second terminal is fitted with the corresponding second terminal groove in interference and in face-to-face contact via the corresponding second side protrusion.
In an embodiment of the invention, each second terminal has a second soldering segment, a second connecting segment and a second contacting segment. The second connecting segment connects a corresponding second soldering segment with a corresponding second contacting segment, and the second side protrusion protrudes from a corresponding second connecting segment.
In an embodiment of the invention, a first convex end of each first terminal is tapered and a first concave end of each first terminal groove is tapered so as to accommodate the corresponding first convex end of the first terminal.
In an embodiment of the invention, the first convex end of each first terminal is tapered toward the shielding plate, and the first concave end of each first terminal groove is tapered toward the shielding plate.
In an embodiment of the invention, each first terminal has a first surface protrusion, and each first surface protrusion protrudes from a surface of the corresponding first terminal in a direction away from the shielding plate, such that each first terminal is close to a bottom portion of the corresponding first terminal groove so as to ensure that the corresponding first convex end of the first terminal is aligned with the corresponding first concave end of the first terminal groove.
In an embodiment of the invention, a second convex end of each second terminal is tapered and a second concave end of each second terminal groove is tapered so as to accommodate the corresponding second convex end of the second terminal.
In an embodiment of the invention, the second convex end of each second terminal is tapered toward the shielding plate, and the second concave end of each second terminal groove is tapered toward the shielding plate.
In an embodiment of the invention, each second terminal has a second surface protrusion, and each second surface protrusion protrudes from a surface of the corresponding second terminal in a direction away from the shielding plate, such that each second terminal is close to a bottom portion of the corresponding second terminal groove so as to ensure that the corresponding second convex end of the second terminal is aligned with the corresponding second concave end of the second terminal groove.
In an embodiment of the invention, the main insulator further includes an engaging recess and a pair of main locking portions. The secondary insulator further includes a pair of secondary locking portions. After the secondary insulator is engaged with the engaging recess, the pair of secondary locking portions is locked with the pair of main locking portions respectively so as to fix a position of the secondary insulator relative to the main insulator.
In an embodiment of the invention, the main insulator further includes a pair of main limiting portions. The secondary insulator further includes a pair of secondary limiting portions. In the process that the secondary insulator is engaged with the engaging recess, the pair of secondary limiting portions are brought into contact with the pair of main limiting portions respectively so as to limit the position of the secondary insulator relative to the main insulator.
In an embodiment of the invention, each first terminal has a first soldering segment, and each second terminal has a second soldering segment. The first soldering segments are extended from the secondary insulator and arranged in a single line, and the second soldering segments are extended from the secondary insulator and arranged in a plurality of lines.
An embodiment of the invention further includes a shielding cover installed on the shielding shell.
In summary, in the invention, by fitting each terminal with the corresponding terminal groove in interference and in face-to-face contact, the terminal is fixed in the terminal groove, and damage to the structure between terminal grooves can be avoided, thereby increasing the structural width between terminal grooves and reducing the width of terminals.
In order to make the aforementioned features and advantages of the invention more comprehensible, embodiments accompanying figures are described in detail below.
