Embodiment approach 1
[0027] Such as figure 1 and figure 2 As shown, the male connector used to transmit high-definition digital signals in this embodiment is composed of male plastic 1, male PCB pad 2, first male terminal 3 and second male terminal 4, the first male The head terminal 3 and the second male terminal 4 are used in pairs, and the two are arranged at intervals and welded on the male PCB pad 2, and the male PCB pad 2 is connected with the first male terminal 3 and the second male terminal 4 Embedded in the groove inside the male plastic 1, the groove can be used in conjunction with the first male terminal 3 and the second male terminal 4; The header soldering piece 16, the male header soldering piece 16 is matched with the male PCB pad 2, which can ensure the reliability of the connection between the male header of the connector and the male PCB pad 2; Both ends are respectively provided with a fastening guide rail 17, between the connector male head and the connector female head (su...
Embodiment approach 2
[0030] This embodiment is a further improvement of Embodiment 1. The main improvement is that the length of the first welding leg 5 of the first male terminal 3 in this embodiment is controlled within the range of 0.5 mm to 0.7 mm; similarly, the first The length of the second welding leg 9 of the second male terminal 4 is also controlled within the range of 0.5 mm to 0.7 mm. Compared with 1.8 millimeters in the prior art, the length of the welding leg in the above-mentioned range is shortened to some extent, which improves the characteristic impedance of the differential signal of the present invention to a certain extent, so that the present invention can be used for the connection of TV and set-top box with HDMI The impedance is more matched, which further ensures the reliability of the connection and the high-speed stability of high-definition signal transmission. Apart from this, other parts in this embodiment are the same as those in Embodiment 1, and will not be repeate...
Embodiment approach 3
[0032] This embodiment is also a further improvement of Embodiment 1. The main improvement is that the thickness of the first strip 6 of the first male terminal 3 in this embodiment is controlled between 0.45 mm and 0.7 mm; correspondingly, The thickness of the second strip 10 of the second male terminal 4 is also controlled between 0.45 mm and 0.7 mm. In the prior art, the strip thickness of the male terminal is generally 1.65 mm. Compared with the prior art, the thickness of the strip of the male terminal in this embodiment is thinner, which is more conducive to improving the characteristics of the differential signal of the connector male. Impedance, when used in the connection of TV and set-top boxes, matches the impedance of HDMI more closely, which further ensures the reliability of the connection and the high-speed stability of high-definition signal transmission. Apart from this, other parts in this embodiment are the same as those in Embodiment 1, and will not be repe...
