Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a heat dissipation type HDMI connector. Background Art

[0002] HDMI is a high-definition multimedia interface. It can not only meet the high-definition 1080P resolution, but also support the most advanced digital audio formats such as DVD Audio, and support eight-channel 96kHz or stereo 192kHz digital audio transmission. The data flow of the HDMI structure is very large, so it will generate a lot of heat during data transmission, and overheating of the connector will affect the quality of its data transmission.

[0003] HDMI usually includes terminals, shielding shells, and insulating bodies, where the insulating body is insulating plastic, the terminals are injection molded on the insulating body, and then the shielding shell wraps the insulating body. The heat of HDMI is usually dissipated through the shielding shell. Since the insulating body is plastic, its thermal conductivity is usually poor, which affects the heat dissipation performance. When transmitting large data, the heat generated by the terminal cannot be transferred from the insulating body in time, and the heat is easily accumulated inside the insulating body. If the insulating body stores too much heat, it will affect the working performance of the connector.

[0004] Therefore, it is urgent to provide a heat dissipation HDMI connector to improve its heat dissipation performance. Utility Model Content

[0005] In view of this, the present invention aims to solve the problems existing in the prior art, and its main purpose is to provide a heat dissipation type HDMI connector, which improves the thermal conductivity of the insulating body and the heat dissipation capacity of the connector, thereby overcoming the shortcomings of the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The present application provides a heat dissipation type HDMI connector, comprising a plurality of terminals, wherein the middle portion of the terminals is bent into an obtuse angle; the terminals are injection molded on an insulating body;

[0009] The shielding shell wraps the insulating body; the heat conducting rod passes through a portion of the graphene paper, and the inner wall of the shielding shell is connected to the heat conducting rod;

[0010] The bottom of the shielding shell is torn to form a stepped grounding foot; the grounding foot can support the shielding shell.

[0011] Preferably, the terminals are arranged in two rows, and the upper row of terminals and the lower row of terminals are arranged in an up-and-down staggered manner.

[0012] Preferably, the cross-section of the middle portion of the terminal is larger than the cross-sections of the pin end and the contact end of the terminal.

[0013] Preferably, the end of the contact end is in a first bent structure and faces the inner side of the tongue plate.

[0014] Preferably, a cantilever supporting the bottom of the shielding shell is provided at the bottom of the base; a first positioning opening is provided at the top of the base, a first positioning piece is torn on the top wall panel of the shielding shell, and the first positioning piece is riveted to the first positioning opening.

[0015] Preferably, the back of the base is provided with a plurality of positioning blocks; the back of the shielding shell is provided with a plurality of second positioning openings; and the positioning blocks are embedded in the second positioning openings.

[0016] Preferably, a wall plate of the shielding shell is torn to form a curved spring piece facing the inside of the shielding shell.

[0017] Preferably, a bent heat dissipation plate is provided on the back of the shielding shell, and a plurality of heat dissipation holes are provided on the heat dissipation plate.

[0018] Preferably, the heat conducting rod is a copper rod or a graphite rod.

[0019] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that the present application provides a heat-dissipating HDMI connector, including a terminal, an insulating body, and a shielding shell.

The thermal conductive rod is injection molded on the upper and lower sides of the base, and the base is affixed with graphene paper; the thermal conductive rod passes through part of the graphene paper, and the inner wall of the shielding shell is connected to the thermal conductive rod. The thermal conductive rod can directly transfer the internal heat of the insulating body to the shielding shell for heat dissipation. At the same time, the graphene paper increases the contact surface of the heat conduction, which allows the heat to diffuse to the shielding shell faster for heat dissipation.

[0020] The grounding pin supports the shielding shell, so that the bottom of the shielding shell is fully in contact with the air, and the heat dissipation performance is better. BRIEF DESCRIPTION OF THE DRAWINGS
