[0044] With the continuous development of display technology, the video transmission rate is getting higher and higher. The current HDMI2.1 transmission rate has reached 48Gbps. The performance requirements for video transmission connectors are getting higher and higher, requiring not only better materials and higher precision, but also more stringent process guarantees; therefore, using the existing production methods, the production difficulty has greatly increased the production cost and greatly reduced the production yield. At the same time, due to the limitations of material properties and production processes, it is still difficult to produce high-performance connectors that fully meet technical standards. The connectors produced often have insufficient yields and high processing costs.

[0045] In view of this, the present invention proposes an HDMI male connector 100. The HDMI male connector 100 proposed by the present invention can be applicable to the transmission protocols of HDMI1.3, HDMI1.4, HDMI2.0, HDMI2.1 and future HDMI connectors with higher speed requirements. Among them, the HDMI male connector 100 of the present invention can be used for ordinary HDMI data cables, and can also be used for various types of electronic composite HDMI data cables and optical fiber HDMI data cables. The present invention shows an HDMI male connector used 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 portion 11, a lower shell portion 12 and a mounting portion 13. The mounting portion 13 is fixed between the upper shell portion 11 and the lower shell portion 12. The mounting portion 13 is provided with a plurality of limiting grooves 131 on opposite sides. 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 bending section 21. The bending section 21 has a first surface 211 and a second surface 211 opposite to each other. 2, 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 plurality of metal terminals 2 close to the upper shell portion 11 in the extension direction thereof, 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 plurality of metal terminals 2 close to the lower shell portion 12 in the extension direction thereof; installed between the upper shell portion 11 and the lower shell portion 12, the plurality of metal terminals 2 are electrically connected to the circuit board 3.

[0047] Specifically, the insulating sleeve 1 is used to wrap the multiple metal terminals 2, and plays the function of fixing and signal shielding the multiple metal terminals 2 to prevent the transmission signals between the multiple metal terminals 2 from interfering with each other. Generally, the insulating sleeve 1 is integrally formed by injection molding, but the requirements for the insulating sleeve 1 suitable for high-speed transmission connectors are relatively high. If an integral molding process is adopted, the yield rate that meets the industry standards of high-speed transmission connectors is not high, resulting in a high cost of manufacturing the connector. Therefore, in this embodiment, the insulating sleeve 1 is divided into two parts, and the insulating sleeve 1 includes 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 multiple limiting grooves 131 are provided on opposite sides of the mounting portion 13, and multiple metal terminals 2 are respectively accommodated in the multiple limiting grooves 131. The limiting grooves 131 can be recessed in the opposite sides of the mounting portion 13, but in this embodiment, multiple partitions 133 are provided on the opposite sides of the mounting portion 13, and the limiting grooves 131 are formed between any two partitions 133, and the limiting grooves 131 limit the metal terminal 2 in the width direction to prevent the metal terminal 2 from moving. In addition, a plug-in cavity 132 is provided at one end of the mounting portion 13, and 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 seat to facilitate signal transmission. The limiting grooves 131 are at least partially connected to the plug-in cavity 132, so that the metal terminal 2 can be exposed to the plug-in cavity 132, so that the metal terminal 2 can form a conflicting relationship with the female seat.

[0049] According to the above content, the mounting portion 13 is mainly used to accommodate multiple metal terminals 2, and the upper shell portion 11 and the lower shell portion 12 need to cooperate with the mounting portion 13 respectively to achieve the fixation of multiple metal terminals 2. In order to better fix the metal terminal 2, the metal terminal 2 is formed with a bending section 21, so that the upper shell portion 11 and the mounting portion 13 are respectively pressed against the two opposite surfaces of the metal terminal 2, that is, the upper shell portion 11 and the mounting portion 13 are respectively pressed against the first surface 211 and the second surface 212 of the metal terminal 2; the lower shell portion 12 and the mounting portion 13 are respectively pressed against the two opposite surfaces of the metal terminal 2, that is, the lower shell portion 12 and the mounting portion 13 are respectively pressed against the first surface 211 and the second surface 212 of the metal terminal 2. The metal terminal 2 is fixed in the above manner, and the metal terminal 2 is limited in the extension direction of the metal terminal 2, thereby replacing the integrally molded plastic sheath, reducing the molding difficulty of the plastic sheath, improving the yield rate of the high-speed signal transmission connector, and reducing the manufacturing cost of the HDMI male connector 100.

[0050] The technical solution of the present invention adopts the method of setting the insulating sheath 1 as an upper shell part 11, a lower shell part 12 and a mounting part 13, installing some of the multiple metal terminals 2 between the upper shell part 11 and the mounting part 13, and installing another part of the multiple metal terminals 2 between the lower shell part 12 and the mounting part 13, and bending the metal terminals 2 to form bending sections 21, so that the upper shell part 11 and the mounting part 13 press against the opposite sides of the multiple bending sections 21, and the lower shell part 12 and the mounting part 13 press against the opposite sides of the multiple bending sections 21, thereby limiting the relative position of the metal terminals 2 in their extension direction, thereby replacing the one-piece molded plastic sheath, reducing the molding difficulty of the plastic sheath, 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 a portion of the elastic abutting section 22 is located in the accommodating groove, and another portion of the elastic abutting section 22 is exposed to the plug-in cavity 132, and is used to form an abutting relationship with the female seat, thereby realizing signal transmission; and the connecting section 23 is used to abut against the circuit board 3, thereby realizing 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 the elastic abutting section 22 and the connecting section 23 are both extended along the extension direction of the metal terminal 2, and a first angle 2a is formed between the bending section 21 and the elastic abutting section 22, and the first angle 2a can be greater than 90°, less than 90°, or equal to 90°, and a second angle 2b is formed between the bending section 21 and the connecting section 23, and 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 the present embodiment, the first angle 2a and the second angle 2b are both 90°. Thus, 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 respectively provided with structures adapted to the bending section 21. The first step surface 111a and the second step surface 111b are two planes adjacent to the first step stage 111. First, the first step stage 111 has two functions. On the one hand, the first step stage 111 presses one side of the bending section 21 through the first step surface 111a; on the other hand, the first step stage 111 presses the connecting section 23 onto the circuit board 3 through the second step surface 111b. Similarly, the second step stage 121 also has two functions. On the one hand, the second step stage 121 presses the other side opposite to the bending section 21 through the third step surface 121a; on the other hand, the second step stage 121 presses the connecting section 23 onto the circuit board 3 through the fourth step surface 121b. The first step stage 111 and the second step stage 121 are used to fix 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 fix the mounting portion 13 between the upper shell 11 and the lower shell 12. 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 plurality of first hooks 124, wherein the plurality of first hooks 124 may correspond to the plurality of first avoidance holes 114 one by one, or two or more first hooks 124 may pass through the same first avoidance hole 114 to be fastened with the upper shell 11. Specifically, the first hook 124 has an extension portion and a hook portion, wherein the extension portion is located in the first avoidance hole 114, and the hook portion is fastened with the surface of the upper shell 11.

[0059] In the present 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 more, which is not specifically limited here.

[0060] In another embodiment, please continue to 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 mounting portion 13 may also be fixed between the upper shell portion 11 and the lower shell portion 12 by respectively engaging with the mounting portion 13 .

The second hooks 125 are distributed on opposite sides of the mounting portion 13, so that the connection between the lower shell 12 and the mounting portion 13 is more stable.

[0063] In order to further strengthen the fixing relationship between the mounting portion 13 and the lower shell portion 12, the lower shell portion 12 is provided with a plurality of third hooks 126 toward the upper shell portion 11, and the mounting portion 13 is provided with a plurality of second avoidance holes 135 corresponding to the plurality of third hooks 126, and the plurality of third hooks 126 pass through the plurality of second avoidance holes 135 and are buckled to the mounting portion 13. In this embodiment, one second avoidance hole 135 is used to allow two third hooks 126 to pass through, so that the buckling strength between the lower shell portion 12 and the mounting portion 13 can be improved.

[0064] In addition, in order to make the upper shell 11 and the mounting portion 13 buckle together, the upper shell 11 is provided with a plurality of fourth hooks 115 toward the lower shell 12 , and the plurality of fourth hooks 115 pass through a plurality of 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 may 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 may be snapped onto the mounting portion 13 separately, or both of the above-mentioned methods may be snapped together.
