[0044] With the continuous advancement of display technology, video transmission rates are increasing, with HDMI 2.1 now reaching 48Gbps. This places increasing demands on the performance of video transmission connectors, demanding not only better materials and higher precision but also more stringent process assurance. Consequently, existing production methods significantly increase production costs and reduce yields. Furthermore, due to limitations in material properties and production processes, producing high-performance connectors that fully meet technical standards remains challenging, often resulting in low yields and high processing costs.

[0045] In light of this, the present invention proposes an HDMI male connector 100. The HDMI male connector 100 proposed in the present invention is compatible with transmission protocols such as HDMI 1.3, HDMI 1.4, HDMI 2.0, HDMI 2.1, and future HDMI connectors with higher speed requirements. The HDMI male connector 100 of the present invention can be used with standard HDMI data cables, as well as various electronic composite HDMI data cables and fiber-optic HDMI data cables. The present invention illustrates an HDMI male connector for an electronic composite HDMI data cable.

[0046] See also Figures 1 to 8 In one embodiment of the present invention, the HDMI male connector 100 includes an insulating sleeve 1, a plurality of metal terminals 2 and a circuit board 3. The insulating sleeve 1 includes an upper shell 11, a lower shell 12 and a mounting portion 13. The mounting portion 13 is fixed between the upper shell 11 and the lower shell 12. A plurality of limiting grooves 131 are provided on opposite sides of the mounting portion 13. The plurality of metal terminals 2 are respectively accommodated in the plurality of limiting grooves 131. The metal terminals 2 are bent to form a bent section 21. The bent section 21 has a first surface 211 and a second surface 211 opposite to each other. 12, the upper shell portion 11 and the mounting portion 13 respectively press against the first surface 211 and the second surface 212 to limit the relative positions of the multiple metal terminals 2 close to the upper shell portion 11 in their extension direction, and the lower shell portion 12 and the mounting portion 13 respectively press against the first surface 211 and the second surface 212 to limit the relative positions of the multiple metal terminals 2 close to the lower shell portion 12 in their extension direction; installed between the upper shell portion 11 and the lower shell portion 12, the multiple metal terminals 2 are electrically connected to the circuit board 3.

[0047] Specifically, the insulating sleeve 1 is used to encase multiple metal terminals 2, securing them and shielding them from interference. This prevents interference between the signals transmitted by the multiple metal terminals 2. Typically, the insulating sleeve 1 is integrally molded using injection molding. However, the requirements for insulating sleeves 1 suitable for high-speed transmission connectors are high. If an integral molding process is used, the yield rate for high-speed transmission connectors that meet industry standards is low, resulting in high connector manufacturing costs. Therefore, in this embodiment, the insulating sleeve 1 is provided in separate parts, each comprising a mounting portion 13, an upper shell portion 11, and a lower shell portion 12.

[0048] The mounting portion 13 is mainly used to accommodate multiple metal terminals 2, so a plurality of limiting grooves 131 are provided on opposite sides of the mounting portion 13 to accommodate the multiple metal terminals 2 in the plurality of limiting grooves 131 respectively. The limiting grooves 131 may be recessed in the opposite sides of the mounting portion 13, but in this embodiment, a plurality of partitions 133 are provided on opposite sides of the mounting portion 13, and the limiting grooves 131 are formed between any two partitions 133. The limiting grooves 131 limit the metal terminals 2 in the width direction to prevent the metal terminals 2 from moving. In addition, a plug-in cavity 132 is provided at one end of the mounting portion 13. The plug-in cavity 132 is used to form an electrical connection between the multiple metal terminals 2 and the circuit board 3 in the female socket to facilitate signal transmission. The limiting grooves 131 are at least partially connected to the plug-in cavity 132, so that the metal terminals 2 can be exposed into the plug-in cavity 132, so that the metal terminals 2 can form a conflicting relationship with the female socket.

[0049] According to the above, the mounting portion 13 is primarily used to accommodate multiple metal terminals 2. The securing of multiple metal terminals 2 requires the upper shell portion 11 and the lower shell portion 12 to cooperate with the mounting portion 13, respectively. To better secure the metal terminals 2, a bent section 21 is formed on the metal terminals 2, so that the upper shell portion 11 and the mounting portion 13 press against two opposing surfaces of the metal terminals 2, namely, the upper shell portion 11 and the mounting portion 13 press against the first surface 211 and the second surface 212 of the metal terminals 2, respectively; and the lower shell portion 12 and the mounting portion 13 press against two opposing surfaces of the metal terminals 2, namely, the lower shell portion 12 and the mounting portion 13 press against the first surface 211 and the second surface 212 of the metal terminals 2, respectively. By securing the metal terminals 2 in this manner and limiting their extension, the aforementioned method replaces the integrally molded plastic sheath, reduces the difficulty of molding the plastic sheath, improves the yield rate of the high-speed signal transmission connector, and reduces the manufacturing cost of the HDMI male connector 100.

[0050] The technical solution of the present invention is to set the insulating sleeve 1 as an upper shell part 11, a lower shell part 12 and a mounting part 13, install some of the multiple metal terminals 2 between the upper shell part 11 and the mounting part 13, and install another part of the multiple metal terminals 2 between the lower shell part 12 and the mounting part 13, and bend the metal terminals 2 to form bent sections 21, so that the upper shell part 11 and the mounting part 13 press against the opposite sides of the multiple bent sections 21, and the lower shell part 12 and the mounting part 13 press against the opposite sides of the multiple bent sections 21, thereby limiting the relative position of the metal terminals 2 in their extension direction, thereby replacing the one-piece molded plastic sleeve, reducing the molding difficulty of the plastic sleeve, improving the quality of the high-speed signal connector, and reducing the production cost of the HDMI male connector 100.

[0051] In one embodiment, see Figure 4 and Figure 8 The metal terminal 2 also includes an elastic abutting section 22 and a connecting section 23, the elastic abutting section 22 and the connecting section 23 are respectively connected to the opposite ends of the bending section 21, the elastic abutting section 22 extends in a direction away from the circuit board 3, the elastic abutting section 22 and the bending section 21 form a first angle 2a, and the connecting section 23 and the bending section 21 form a second angle 2b.

[0052] Specifically, the metal terminal 2 further includes an elastic abutting section 22 and a connecting section 23. It should be noted that the elastic abutting section 22 is partially located in the accommodating groove, and another portion of the elastic abutting section 22 is exposed in the plug-in cavity 132, and is used to form an abutting relationship with the female socket to achieve signal transmission; while the connecting section 23 is used to abut against the circuit board 3 to achieve signal transmission. The elastic abutting section 22 and the connecting section 23 are respectively connected to the opposite ends of the bending section 21, and both the elastic abutting section 22 and the connecting section 23 extend along the extension direction of the metal terminal 2. A first angle 2a is formed between the bending section 21 and the elastic abutting section 22. The first angle 2a can be greater than 90°, less than 90°, or equal to 90°. A second angle 2b is formed between the bending section 21 and the connecting section 23. The second angle 2b can be greater than 90°, less than 90°, or equal to 90°. The sum of the first angle 2a and the second angle 2b is approximately 180°. In this embodiment, the first angle 2a and the second angle 2b are both 90°. In this way, the upper shell and the lower shell have a good limiting effect on the metal terminal 2.

[0053] In one embodiment, see Figure 3 and Figure 4 The upper shell portion 11 presses the multiple connecting sections 23 close to the upper shell portion 11 on one side of the circuit board 3, and the lower shell portion 12 presses the multiple connecting sections 23 close to the lower shell portion 12 on the other side opposite to the circuit board 3.

[0054] In this embodiment, the upper shell portion 11 and the lower shell portion 12 respectively crimp the multiple connecting sections 23 on the opposite sides of the circuit board 3, so the signal connection between the multiple metal terminals 2 and the circuit board 3 can be achieved only by crimping. In addition, the multiple connecting sections 23 and the circuit board 3 can also be fixed by welding, thereby further enhancing the stability of signal transmission between the multiple metal terminals 2 and the circuit board 3.

[0055] In one embodiment, see Figure 4 、 Figure 6 、 Figure 7 and Figure 8The upper shell portion 11 is provided with a first step 111 facing the multiple metal terminals 2, and the first step 111 has adjacent first step surfaces 111a and second step surfaces 111b. The first step 111 presses the multiple first surfaces 211 through the first step surface 111a, and the first step 111 presses the multiple connecting sections 23 onto the circuit board 3 through the second step surface 111b; the lower shell portion 12 is provided with a second step 121 facing the multiple metal terminals 2, and the second step 121 has adjacent third step surfaces 121a and fourth step surfaces 121b. The second step 121 presses the multiple first surfaces 211 through the third step surface 121a, and the second step 121 presses the multiple connecting sections 23 onto the circuit board 3 through the fourth step surface 121b.

[0056] It should be noted that the upper shell portion 11 and the lower shell portion 12 are each provided with structures adapted to mate with the bent section 21. The first stepped surface 111a and the second stepped surface 111b are two adjacent planes of the first stepped portion 111. The first stepped portion 111 has two functions: first, it presses against one side of the bent section 21 via the first stepped surface 111a; second, it presses the connecting section 23 against the circuit board 3 via the second stepped surface 111b. Similarly, the second stepped portion 121 also has two functions: first, it presses against the opposite side of the bent section 21 via the third stepped surface 121a; second, it presses the connecting section 23 against the circuit board 3 via the fourth stepped surface 121b. The first and second stepped portions 111, 121 secure and limit the metal terminal 2.

[0057] In one embodiment, see Figure 3 The upper shell portion 11 and the lower shell portion 12 are buckled together to fix the mounting portion 13 between the upper shell portion 11 and the lower shell portion 12 .

[0058] It should be noted that the upper shell 11 and the lower shell 12 are fastened together to secure the mounting portion 13 therebetween. Specifically, the lower shell 12 is provided with a plurality of first hooks 124 facing the upper shell 11, and the upper shell 11 is provided with a plurality of first avoidance holes 114 corresponding to the first hooks 124. The first hooks 124 can correspond one-to-one with the first avoidance holes 114, or two or more first hooks 124 can pass through the same first avoidance hole 114 to engage with the upper shell 11. Specifically, the first hook 124 comprises an extension portion and a hook portion. The extension portion is located within the first avoidance hole 114, while the hook portion fastens to the surface of the upper shell 11.

[0059] In this embodiment, the number of the first hooks 124 is set to two, so that the connection relationship between the upper shell 11 and the lower shell 12 is more stable. Of course, the number of the first hooks 124 can be set to one, or the number of the first hooks 124 can be set to multiple, which is not specifically limited here.

[0060] In another embodiment, please refer to Figure 3 The upper shell portion 11 and the lower shell portion 12 are respectively buckled with the mounting portion 13 .

[0061] It should be noted that the upper shell portion 11 and the lower shell portion 12 may also be buckled with the mounting portion 13 respectively, so as to fix the mounting portion 13 between the upper shell portion 11 and the lower shell portion 12 .

[0062] Specifically, the lower shell portion 12 is provided with a plurality of second hooks 125 facing the upper shell portion 11, and the mounting portion 13 is provided with a plurality of buckle grooves 134 communicating with the outside of the mounting portion 13. The plurality of second hooks 125 are buckled into the buckle grooves 134. It should be noted that the plurality of second hooks 125 are buckled into the buckle grooves 134. In this embodiment, the second hooks 125 correspond one to one with the buckle grooves 134. The second hooks 125 are distributed on opposite sides of the mounting portion 13, thereby further strengthening the connection between the lower shell portion 12 and the mounting portion 13.

[0063] To further strengthen the secure connection between the mounting portion 13 and the lower housing portion 12, the lower housing portion 12 is provided with a plurality of third hooks 126 facing the upper housing portion 11. The mounting portion 13 is provided with a plurality of second avoidance holes 135 corresponding to the third hooks 126. The third hooks 126 pass through the second avoidance holes 135 and are fastened to the mounting portion 13. In this embodiment, one second avoidance hole 135 is used to pass two third hooks 126, thereby enhancing the fastening strength between the lower housing portion 12 and the mounting portion 13.

[0064] In addition, in order to buckle the upper shell 11 and the mounting portion 13 , the upper shell 11 is provided with a plurality of fourth hooks 115 toward the lower shell 12 . The fourth hooks 115 pass through the second avoidance holes 135 and are buckled to the mounting portion 13 .

[0065] It should be noted that, in this embodiment, the fourth hook 115 in this embodiment also passes through the above-mentioned second avoidance hole 135 and is engaged with the mounting portion 13, which can avoid the need to open additional avoidance holes and save processing time and cost, wherein each second avoidance hole 135 is used to allow two fourth hooks 115 to pass through.

[0066] In addition, the insulating sheath 1 can be such that the mounting portion 13 is fixed between the upper shell portion 11 and the lower shell portion 12 only by snapping the upper shell portion 11 and the lower shell portion 12 together, or the upper shell portion 11 and the lower shell portion 12 can be snapped onto the mounting portion 13 separately, or both of the above-mentioned methods can be snapped together. The above embodiments are all optional embodiments of the present utility model.

[0067] In one embodiment, please continue to refer to Figure 3 A first positioning hole 31 is provided on the circuit board 3, a second positioning hole 122 corresponding to the first positioning hole 31 is provided on the lower shell 12, and a positioning column 112 is protruding toward the first positioning hole 31 on the upper shell 11, so that the positioning column 112 passes through the first positioning hole 31 and extends into the second positioning hole 122.

[0068] It should be noted that, in order to position and install the upper shell 11, the lower shell 12, and the mounting portion 13, a first positioning hole 31 is provided on the circuit board 3, a second positioning hole 122 is provided on the lower shell 12, and a positioning post 112 is provided on the upper shell 11 protruding toward the first positioning hole 31, so that the positioning post 112 passes through the first positioning hole 31 and extends into the second positioning hole 122. The positioning post 112 is used to position and install the circuit board 3 between the upper shell 11 and the lower shell 12.

[0069] In one embodiment, see Figure 2 The HDMI male connector 100 also includes a metal shell 6, which wraps the outer side of the insulating sleeve 1. A first elastic buckle 61 is provided on the inner side of the metal shell 6.
