Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a connector housing (iron shell) structure design that is advantageous for electroplating. Background Technology

[0002] Connectors are mainly used in computer peripherals, servers, routers, switching equipment and other products for data transmission and peripheral connection, and are widely used in networking, communication, automation control and other fields.

[0003] As electronic products become increasingly feature-rich and the market becomes more diversified, the requirements for product structure are increasing. To improve the stability of connectors, the overall electroplating requirements for connector housings (iron shells) are becoming increasingly stringent.

[0004] In conventional HDMI connectors, the two sides of the metal shell are either pressed together or directly attached, making it difficult for the electroplating solution to penetrate and coat the metal. The adjacent parts of the two sides of the metal shell are uncoated, and the metal shell is easily corroded during environmental testing. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the purpose of this invention is to provide a design that is conducive to the electroplating structure of connector housing (iron shell) and facilitates the electroplating solution to fully plate the iron shell surface with a coating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connector housing structure includes an insulating base, a housing, and a terminal group, wherein the insulating base is partially embedded in the housing, and the terminal group is embedded in the insulating base.

[0008] One end of the housing is provided with a plug-in interface, the other end of the housing away from the plug-in interface is provided with an opening, and the two sides of the housing are provided with rearward extending sidewalls, which are located on both sides of the opening.

[0009] The side wall has an extension with a protruding opening extending outward. The end of the extension away from the insertion interface has a folded part, and the end of the folded part away from the extension has a flanged part parallel to the extension. The flanged part is arranged parallel to the extension and there is a certain distance between the flanged part and the extension. The distance D between the flanged part and the extension is greater than or equal to 0.1mm.

[0010] Several flow channels are provided on the side of the flange near the extension. The flow channels are arranged alternately on the inner wall of the flange and are arranged in a continuous manner on the inner wall of the flange.

[0011] Furthermore, in some embodiments, the folded portion is provided at the end of the extension portion with the folded portion bent outwards in the opposite direction; the length of the folded portion is greater than the length of the extension portion, and the distance D between the folded portion and the adjacent sidewall of the extension portion is ≥0.1mm.

[0012] Furthermore, in some embodiments, the flow channel is longitudinally arranged on the inner sidewall of the flange portion;

[0013] The end of the flange that is away from the folded part has an inwardly bent section.

[0014] Furthermore, in some embodiments, the forward end of the flanged portion protruding from the extension portion is provided with a bent portion, and the end of the bent portion away from the flanged portion is provided with a longitudinally extending second insertion piece, the second insertion piece and the extension portion being located on the same plane.

[0015] Furthermore, in some embodiments, the opening is provided with rearwardly extending sidewalls on both sides; the sidewalls are provided with extensions that protrude outward from the opening;

[0016] A positioning groove is provided at the end of the side wall away from the insertion interface, and the positioning groove is located between the side wall and the extension;

[0017] The extension portion has a first plug-in piece that protrudes forward on the side away from the sidewall;

[0018] Several spring clips are provided on the upper and lower surfaces of the shell.

[0019] Furthermore, in some embodiments, the second plug-in piece and the extension are spaced apart by a certain distance, the distance between the second plug-in piece and the extension is equal to the length of the bent portion, and the second plug-in piece and the first plug-in piece are arranged in the same direction.

[0020] Furthermore, in some embodiments, the insulating seat includes a rear seat, one end of which protrudes outward from the opening of the housing, and a portion of the rear seat extends outside the opening; the side of the rear seat is disposed adjacent to the extension.

[0021] Furthermore, in some embodiments, the rear seat has a tongue plate on the side facing the insertion interface, and the tongue plate is disposed inside the housing; the rear seat has a positioning platform on the side near the insertion interface, the positioning platform is disposed between the tongue plate and the rear seat, and the positioning platform is embedded in the housing; the rear end (rear end) has positioning blocks on both sides that match the positioning groove.

[0022] Furthermore, in some embodiments, the rear seat has side plates extending toward the insertion interface on both sides, and the side plates are disposed on the outer side of the housing surface.

[0023] The second connector is positioned on the outer side of the side plate.

[0024] Furthermore, in some embodiments, the rear seat is provided with a clearance groove, and the terminal group on the rear seat extends through the clearance groove and is disposed on the tongue plate; the terminal group is disposed on the bottom of the clearance groove.

[0025] This invention is applied to HDMI connectors. The distance between the two sides of the connector's metal shell flange structure is greater than or equal to 0.1mm, which increases the flow channel, making it easier for the electroplating solution to flow in and form a coating. It also makes the connector less susceptible to corrosion during environmental testing. Attached Figure Description
