Description

Technical Field

[0001] This invention relates to board-end connectors, and more particularly to a grounding structure and board-end connector for a USB board-end connector. Background Technology

[0002] USB board connectors are electrical connectors used to enable electrical conduction between circuit boards and cables or other electronic devices. The board connector includes a shielding shell that covers the outside of the terminals to prevent the influence of external electrostatic or electromagnetic induction on the internal current or signal. Maintaining the stability of the connection between the shielding shell and the grounding terminal is an effective means of ensuring the shielding effect of the shielding shell. In the prior art, the connection between the shielding shell and the grounding terminal of the USB board connector is achieved by overlapping the upper lugs of the shielding shell with the lugs of the grounding terminal. This connection method has poor reliability; often, the two lugs of the USB board connector will loosen, affecting the shielding effect of the USB board connector and rendering the shielding shell ineffective. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a grounding structure and board-end connector for a USB board-end connector with reliable grounding.

[0004] The technical solution of the present invention is as follows: a grounding structure for a USB board connector is provided, including a shielding shell of the USB board connector and a grounding terminal disposed on the shielding shell. A tab extending directly from the shielding shell is provided on the rear side of the shielding shell. The tab includes an extension section and an inwardly bent section. One end of the extension section is connected to the shielding shell, and the other end of the extension section is connected to one end of the inwardly bent section through a first arc section. A terminal tab extending outward is provided on one side of the grounding terminal. After a portion of the lower part of the terminal tab is cut off, the portion is bent backward to form a stop. The inwardly bent section abuts against the terminal tab and is in close contact with the stop.

[0005] As an improvement to the present invention, the lug further includes a backward bending section, which is connected to the other end of the inward bending section via a second arc segment; the backward bending section is hooked onto the stop lug.

[0006] The present invention also provides a USB board connector, which includes the grounding structure of the USB board connector described above.

[0007] The present invention also provides a USB board-end connector, including a USB-A board-end connector body and a plastic shell formed by one-time injection molding. The USB-A board-end connector body is disposed on the plastic shell. A shielding shell is disposed inside the plastic shell, and a grounding terminal is disposed on the shielding shell. A tab extending directly from the shielding shell is provided on the rear side of the shielding shell. The tab includes an extension section and an inwardly bent section. One end of the extension section is connected to the shielding shell, and the other end of the extension section is connected to one end of the inwardly bent section through a first arc section. A terminal tab extending outward is provided on one side of the grounding terminal. A portion of the lower part of the terminal tab is cut off and then bent backward to form a stop. The inwardly bent section abuts against the terminal tab and is in close contact with the stop.

[0008] As an improvement to the present invention, the front width H1 of the front side of the plastic housing 2 on the side of the connector near the board end is greater than the rear width H2 of the rear side of the plastic housing on the side away from the connector near the board end.

[0009] As an improvement to the present invention, the left and right sides of the plastic housing are bent outwards from the rear side to near the front side to form two outward sides.

[0010] As an improvement to the present invention, the insertion depth D1 of the USB-A board connector body is greater than or equal to 9 mm and less than or equal to 11 mm.

[0011] As an improvement to the present invention, it also includes a Type-C board-end connector body, which is disposed on the plastic housing and located below the USB-A board-end connector body.

[0012] As an improvement to the present invention, the socket surface of the USB-A board connector body and the socket surface of the Type-C board connector body are in the same plane as the front side of the plastic shell.

[0013] As an improvement to the present invention, the main body of the USB-A board-end connector is a USB-A 2.0 or USB-A 3.0 board-end connector.

[0014] This invention employs a structure in which a lug extending directly from the shielding housing is provided on the rear side of the shielding housing. The lug includes an extension section and an inwardly bent section. One end of the extension section is connected to the shielding housing, and the other end of the extension section is connected to one end of the inwardly bent section via a first arc section. A terminal lug extending outward is provided on one side of the grounding terminal. A portion of the lower part of the terminal lug is cut off and then bent backward to form a stop. The inwardly bent section abuts against the terminal lug and is in close contact with the stop. Therefore, this invention has the advantage of highly reliable grounding of the grounding terminal.

[0015] Furthermore, this invention employs a plastic shell molded in one piece, with the USB-A board-end connector body disposed on the plastic shell. The front width of the front side of the plastic shell on the side near the board-end connector's insertion interface is greater than the rear width of the rear side of the plastic shell on the side away from the board-end connector's insertion interface, resulting in a larger front area. This facilitates a larger bonding area when bonding this invention to other device panels, improving the bonding reliability between this invention and other device panels. Additionally, the insertion depth of the USB-A board-end connector body is set to be selectable between 9mm and 11mm, which increases the insertion depth of the line-end connector and improves the insertion reliability of the USB-A board-end connector body.

In this invention, the shielding shell 101 is a steel shell, and the grounding terminal 102 is made of copper sheet, or it can be made of copper sheet and then plated with a nickel layer.

[0023] Preferably, the lug 1011 further includes a backward bending section 10113, which is connected to the other end of the inward bending section 10112 via a second arc section 10115; the backward bending section 10113 is hooked onto the lug 1022.

[0024] Preferably, a latch 1023 is provided on the upper part of the terminal lug 1021, and the backward bending section 10113 passes through the latch 1023 and then hooks onto the stop lug 1022.

[0025] The present invention also provides a USB board connector, which includes the grounding structure of the USB board connector described above.

[0026] Please see Figure 4-6The present invention also provides a USB board-end connector, including a USB-A board-end connector body 1 and a plastic shell 2 formed by one-time injection molding of plastic. The USB-A board-end connector body 1 is disposed on the plastic shell 2. A shielding shell 101 is provided inside the plastic shell 2, and a grounding terminal 102 is disposed in the shielding shell 101. A latch 1011 extending directly from the shielding shell 101 is provided on the rear side of the shielding shell 101. The latch 1011 includes an extension section 10111 and an inwardly bent section 10112. One end of the extension segment 1 is connected to the shielding housing 101, and the other end of the extension segment 10111 is connected to one end of the inwardly bent segment 10112 through the first arc segment 10114; a terminal lug 1021 extending outward is provided on one side of the grounding terminal 102.
