Description

Technical Field

[0001] The utility model relates to the field technology of HDMI connector, in particular to an HDMI plug connector and an electronic product. Background Art

[0002] HDMI, or High-Definition Multimedia Interface, can transmit audio and video signals, etc. Its shielding effect has always been a concern in the industry.

[0003] CN205051091U discloses a new type of HDMI plug tongue, which is embedded with an HDMI shielding shell. The HDMI plug tongue includes a plug tongue body, and also includes a reinforcing rib and a wing arranged on the plug tongue body. The reinforcing rib is a protrusion that is horizontally surrounded and arranged on the rear end of the plug tongue body. The wing is formed by folding outward vertically from an extended portion formed by horizontally extending along the rear end of the plug tongue body. An annular card slot is formed between the wing and the reinforcing rib, and the card slot is adapted to the inner folded portion of the front port of the HDMI shielding shell. When producing an HDMI connector, the rear end of the HDMI plug tongue is embedded in the front port of the shielding shell. The card slot is adapted to the inner folded portion of the front port of the HDMI shielding shell, and is used to clamp the inner folded portion of the front end of the shielding shell located in the vertical section when the HDMI plug tongue is embedded with the shielding shell, so that the wing, the reinforcing rib and the inner folded portion of the shielding shell fit each other to prevent external interference with the video signal.

[0004] During production design, the reserved annular slot is determined by the relative position between the reinforcing rib and the wing, and the reserved size is usually a tight-fitting size. However, during actual production, since the reinforcing rib is a protrusion that is laterally arranged on the rear end of the tongue body, as a whole ring, it is difficult to produce and process it. In addition, it is often difficult to control the rear end of the reinforcing rib to be in a flush position in the left and right directions. In order to ensure smooth embedding of the shielding shell, the slot cannot be too small. The slot size that can ensure smooth embedding is prone to unreliable contact after embedding, which is subsequently remedied by welding, making the production more complicated.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

The rear end of the metal shielding shell 30 is vertically folded outward to form a stopper 32. The stopper 32 is provided at two locations, located on the left and right sides respectively; the stopper 32 is limited by the front side of the shoulder 212 of the tailstock 22, and the convex bumps 31 are all located on the front side of the stopper 32 to form a front-to-back gap between the rear end of the convex bump 31 and the front end of the stopper 32, and the convex bumps 31 and the stopper 32 are staggered with each other in the left-right direction. The rear end of the top and / or bottom of the metal shielding shell 30 is extended backward with an extension plate, and an auxiliary stopper is provided on the extension plate, and the auxiliary stopper is located on the rear side of the convex bump 31.

[0033] The auxiliary stopper is set between two convex humps 31 with a left-right spacing to form a multi-point contact. The left and right sides of the bottom of the metal shielding shell 30 are bent upward and extended as a whole, and then bent inward and spliced ​​to form a top, and its splicing line is located between the two convex humps 31 with a left-right spacing; the auxiliary stopper is vertically folded outward from the extension plate as a whole, and its size in the front-to-back direction is greater than the thickness of the extension plate. The auxiliary stopper includes a left auxiliary stopper and a right auxiliary stopper, for example: the auxiliary stopper 33 on the left and right sides of the bottom, the left auxiliary stopper and the right auxiliary stopper are respectively bent upward and extended from the splicing edges on both sides, and the left auxiliary stopper and the right auxiliary stopper are arranged opposite to each other on the left and right. The left auxiliary stopper and the right auxiliary stopper at the top are welded and fixed into one body, for example: the auxiliary stopper 35 at the top left and right sides are usually spliced ​​in a dovetail groove type, and the left auxiliary stopper and the right auxiliary stopper also play a role in improving the splicing firmness of the metal shielding shell 30. The extension plate is provided with a clamping hole 34, the insertion part 21 and the tail stock 22 are separately provided, and the corresponding top and / or bottom of the tail stock 22 are provided with a clamping protrusion 211, the tail stock 22 is assembled at the rear end of the insertion part 21, and the clamping protrusion 211 is clamped into the clamping hole 34 to form an inverted lock. The auxiliary stop portion is located on the side of the card hole 34, and the auxiliary stop portion is formed by folding vertically outward from the area where the card hole 34 is located. In this embodiment, the auxiliary stop portions 33 on the left and right sides of the bottom, and the auxiliary stop portions 35 on the left and right sides of the top are all located on the sides of the corresponding card holes 34, and their dimensions in the front and rear directions can be larger, larger than the thickness of the stop sheet 32. Therefore, the auxiliary stop portion can provide a stronger rear stop force.

[0034] The outer cover of the tailstock 22 is provided with a metal tail shell, and the metal tail shell includes an upper shell 41 and a lower shell 42. The upper shell 41 and the lower shell 42 are wrapped around the outside of the tailstock 22 and are buckled and fixed up and down. For example, buckles are provided on the outer surfaces of the left and right side walls of the upper shell 41, and buckle grooves are provided on the corresponding left and right side walls of the lower shell 42. After the upper shell and the lower shell are buckled with each other, the buckles are inserted into the buckle grooves; the front end of the upper shell 41 and / or the lower shell 42 is provided with a front baffle 401, and the front baffle 401 is embedded in the front and rear gaps, and the convex bump 31 stops at the front side of the front baffle 401 to form contact, and the front baffle 401 stops at the front side of the stopper 32 and the auxiliary stopper to form a close contact positioning. The front baffle 401 and the stopper 32 are stacked in the front and rear directions to jointly form an annular shielding portion surrounding the outer periphery of the metal shielding shell 30. Furthermore, the tail portion of the metal tail shell is integrally connected with a tail clip, and usually the clamping claws are fixed on the outer periphery of the wire.

[0035] Also, an electronic product is provided, which is connected with an HDMI connector, wherein the HDMI connector is the HDMI plug connector described above.
