Description

Technical Field

[0001] The utility model relates to the field of data cables, and particularly to an HDMI connector structure of an audio data cable. Background Art

[0002] HDMI is a fully digital video and audio transmission interface that can transmit uncompressed audio and video signals. However, the existing HDMI data cable structure generally sets hook pins at the connector position to ensure the holding force after HDMI insertion. However, this structure has relatively high production costs and assembly costs. At the same time, the existing HDMI connectors generally adopt a structure of PIN pins injection molded, so their bonding degree is also relatively high, but there are also problems during the injection molding process. Of course, there are also existing split assembly structures, but their plastic bonding degree and PIN pin holding force are poor, affecting the use stability. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose an HDMI connector structure of an audio data cable, aiming to improve the existing connector structure to make it convenient for assembly and the holding force of the PIN pins is relatively stable.

[0004] To achieve the above purpose, the utility model proposes an HDMI connector structure of an audio data cable, including,

[0005] An upper row plastic shell, on which a plurality of upper row PIN pins are arranged;

[0006] A lower row plastic shell, on which a plurality of lower row PIN pins are arranged;

[0007] The upper row plastic shell and the lower row plastic shell are combined through a buckling structure to form a rear shell;

[0008] A front shell, which is a shell with an inner cavity in the middle. The top wall and the bottom wall of the front part of the inner cavity are provided with an upper row guide pin groove and a lower row guide pin groove,

[0009] The rear part of the inner cavity is provided with a positioning groove for installing the rear shell,

[0010] And enabling the upper row PIN pins and the lower row PIN pins to extend into the upper row guide pin groove and the lower row guide pin groove;

[0011] The upper row PIN pins and the lower row PIN pins are arranged in a staggered manner, and a first convex peak and a second convex peak are respectively arranged in the middle of the upper row PIN pins and the middle of the lower row PIN pins, and the first convex peak and the second convex peak are arranged in a staggered and overlapping manner;

[0012] An iron shell, which can cover and clamp the outer peripheral wall of the front shell and the middle part of the rear shell inside.

[0013] In the actual design, each part of the joint is made into a separate plastic part, which facilitates production and assembly, and at the same time, the defective rate is relatively low. Moreover, by staggering the upper row of PIN pins and the lower row of PIN pins, the first convex peak and the second convex peak form a staggered cross-overlapping structure, realizing the contact between the male plastic housing and the corresponding terminals, enabling the two to maintain a relatively high pre-pressure, ensuring the stability of the engagement and use, and thus eliminating the need for a dedicated locking structure to ensure the clamping force.
