[0037] Please refer to Figures 1 to 19 As shown in the illustration, this utility model discloses an electrical connector 100, which includes an insulating body 1, a terminal module 2 at least partially installed within the insulating body 1, and a shielding shell 3 covering the insulating body 1. In the illustrated embodiment, the electrical connector 100 is an HDMI connector. The electrical connector 100 is used to connect to a plurality of cables (not shown). The electrical connector 100 mates with a mating connector (not shown) along a mating direction to achieve data transmission. Because the mating direction of the electrical connector 100 and the mating connector in this embodiment is... Figure 1 The front-to-back direction, also known as the docking direction, is defined as the front-to-back direction. Please refer to... Figure 1 As shown, the electrical connector also has a left-right direction and a right-down direction, wherein the right-down direction, the left-right direction, and the front-back direction are mutually perpendicular. Of course, those skilled in the art will understand that in other embodiments, the electrical connector 100 may also be other types of electrical connectors.

[0038] Please refer to Figures 1 to 6As shown, the electrical connector includes an insulating body 1, a terminal module 2, and a shielding shell 3. The terminal module 2 is at least partially installed inside the insulating body 1, and the shielding shell 3 is at least partially fitted outside the insulating body 1. The terminal module 2 includes a first terminal module 4, a second terminal module 5, and a shielding sheet 6. The first terminal module 4 includes a first insulating block 41 and a plurality of first signal terminals 42 fixed on the first insulating block 41. The second terminal module 5 includes a second insulating block 51 and a plurality of second signal terminals 52 fixed on the second insulating block 51. The first signal terminals 42 and the second signal terminals 52 together form a plurality of differential signal pairs, and the plurality of differential signal pairs have multiple terminal tails located in the same plane. In a specific embodiment, there are six differential signal pairs. Differential transmission is a signal transmission technology that differs from the traditional approach of one signal line and one ground line (single-ended signal). Differential transmission transmits signals on both (or other even-numbered) lines, and the amplitudes of the two (or other even-numbered) signals are equal and their phases are opposite. The signals transmitted on these two (or other even-numbered) lines are differential signals. Differential signal transmission has at least two advantages: 1. Strong anti-interference capability. Interference noise is generally applied equally and simultaneously to the two (or other even-numbered) signal lines, with a difference of 0, meaning the noise does not affect the logical meaning of the signal. 2. Effective suppression of electromagnetic interference (EMI). Because the two (or other even-numbered) lines are very close and have equal signal amplitudes, the amplitudes of the coupled electromagnetic fields between these two (or other even-numbered) differential signal transmission lines and the nearby ground line (described in detail later) are also equal. Simultaneously, their signal polarities are opposite, and their electromagnetic fields cancel each other out. Therefore, electromagnetic interference to the outside world is minimal.

[0039] Please refer to Figure 11 and Figure 12 As shown, the shielding sheet 6 is a one-piece structure made of metal material. In a specific embodiment, the shielding sheet 6 is made by stamping metal material; in other embodiments, it can also be made by laser cutting or other methods. The shielding sheet 6 includes a base 61, a plurality of grounding contacts 63, and a plurality of grounding solder feet 62. The base 61 is clamped and positioned between the first insulating block 41 and the second insulating block 51. The grounding solder feet 62 and the grounding contacts 63 extend in opposite directions from the front and rear ends of the base 61. The plurality of grounding solder feet 62 are arranged in the same plane and separate the terminal tails of two adjacent sets of differential signal pairs. The plurality of grounding solder feet 62 are the ground wires mentioned above. This arrangement of the shielding sheet 6 with multiple grounding solder feet 62 simplifies the forming of the grounding solder feet 62, allows for quick connection to the cable grounding part (not shown), improves welding efficiency, ensures welding quality, reduces data interference between differential signal pairs (six sets in a specific embodiment), and improves the shielding performance of the electrical connector 100.

[0040] Please refer to Figure 9 , Figure 13 , Figures 15 to 17 As shown, one of the first insulating block 41 and the second insulating block 51 has a row of protrusions 511. In a specific embodiment, the second insulating block 51 has a row of protrusions 511; however, in other embodiments, the protrusions 511 can also be provided on the first insulating block 41. Each grounding solder foot 62 is held between two adjacent protrusions 511. The protrusions 511 facilitate the positioning of the shielding sheet 6 in the left-right direction by the positioning of each grounding solder foot 62 when it is held and positioned between the first insulating block 41 and the second insulating block 51 in the vertical direction, thus preventing the shielding sheet 6 from easily wobbling in the left-right direction.

[0041] Please refer to Figure 9 , Figure 10 and Figure 19 As shown, the second insulating block 51 has a first base 510. Each of the bosses 511 protrudes upward from the first base 510, and multiple bosses 511 are connected through the first base 510. Each boss 511 has an upper assembly surface 5111 facing away from the first base 510 and exposed at the tail end of the first insulating block 41, and a root portion 5112 connected to the first base 510. The height of each boss 511 from the upper assembly surface 5111 to the root portion 5112 is equal to the thickness of the grounding solder foot 62. With this configuration, when the shielding sheet 6 is positioned on the second insulating block 51, it ensures that each grounding solder foot 62 is flush with the upper assembly surface 5111. That is, the upper assembly surface 5111 is the same plane where the tail ends of multiple terminals of several sets of differential signal pairs are located, which is exposed at the tail end of the first insulating block 41, ensuring the visibility of the plane and facilitating subsequent soldering operations with cables.

[0042] Please refer to Figures 1 to 19As shown, in a specific embodiment, since the electrical connector 100 is an HDMI connector, there are five grounding solder feet 62. The terminal tail includes seven first terminal tails 422 of the first signal terminal 42 and seven second terminal tails 522 of the second signal terminal 52. The first terminal tails 422 and the second terminal tails 522 are exposed on the upper assembly surface 5111. Specifically, the first terminal tails 422 and the second terminal tails 522 are flush with each other on the upper assembly surface 5111, which helps to ensure visibility during assembly and facilitates subsequent soldering operations with cables. The seven first terminal tails 422 are assembled into the boss 511, and the seven second terminal tails 522 are disposed in the boss 511. In a specific embodiment, the second terminal tails 522 are embedded in the boss 511 to distinguish them from the assembly method of the first terminal tails 422 within the boss 511. It should be noted that the embedding described here can be partial or full embedding, to accommodate the need to clamp the shielding sheet 6 between the two separately arranged terminal modules. The two terminal modules are the first terminal module 4 and the second terminal module 5. That is, because the first signal terminal 42 is fixed to the first insulating block 41, and the second signal terminal 52 is fixed to the second insulating block 51, the seven first terminal tails 422 of the first signal terminal 42 can only be assembled into the protrusions 511 provided on the second insulating block 51. Of course, the first conductive terminal 42 also includes seven first terminal heads 421, and the second conductive terminal 52 also includes seven second terminal heads 521. The electrical connector 100 has a front socket 10 for the mating connector to be inserted. The first terminal head 421 extends to a position close to and above the front connector 10, and the second terminal head 521 extends to a position close to and below the front connector 10. The five grounding contacts 63 include three first grounding contacts 631 that bend upwards and two second grounding contacts 632 that bend downwards. The three first grounding contacts 631 and the seven first terminal heads 421 are arranged together above the front connector 10 in a row, and the two second grounding contacts 632 and the seven second terminal heads 521 are arranged together below the front connector 10 in a row.

[0043] Please refer to Figures 7 to 10 as well as Figures 13 to 17As shown, the first insulating block 41 includes a plurality of first blocks 410, and a plurality of first terminal tails 422 are divided into arrays, with each array of first terminal tails 422 being held by one first block 410. In a specific embodiment, the first insulating block 41 includes four first blocks 410, with each pair of adjacent first terminal tails 422 held by one first block 410, and the seventh first terminal tail 422 held by a single first block 410. The second insulating block 51 has receiving grooves 5110 on a portion of the protrusions 511, and the first blocks 410 are correspondingly positioned within the receiving grooves 5110. The alignment and fit between the first blocks 410 and the receiving grooves 5110 ensures the stability and accuracy of the positioning of the first terminal tails 422 within the protrusions 511.

[0044] Please refer to Figures 11 to 19 As shown, the rear portion of the shielding plate 6 away from the front insertion interface 10 includes a first sidewall 611 and a second sidewall 612 arranged opposite each other in the left-right direction, and a first transverse wall 613 and a second transverse wall 614 arranged opposite each other in the front-back direction. The first sidewall 611 and the second sidewall 612 are bent relative to the first transverse wall 613 and the second transverse wall 614. The first sidewall 611, the first transverse wall 613, the second sidewall 612 and the second transverse wall 614 are connected end to end to form a rear opening 601. Figure 11 The dashed arrow in the figure indicates the width of the rear opening 601 in the left-right direction. It can be understood that in this specific embodiment of the present invention, the width of the rear opening 601 in the left-right direction is greater than the length of the rear opening 601 in the front-back direction. The first transverse wall 613 and the second transverse wall 614 each have an inner wall surface facing the rear opening 601. One end of each grounding solder foot 62 is connected to the inner wall surface of the first transverse wall 613 and the other end is connected to the inner wall surface of the second transverse wall 614. This arrangement facilitates the parallel front-back and spaced left-right arrangement of the grounding solder feet 62 within the same plane, making it easier to separate the tails of multiple terminals of the differential signal pair according to differential requirements.

[0045] Please refer to Figure 11 As shown, there are N grounding solder feet 62, which divide the rear opening 601 into N+1 slots 602. The tail of the terminal is accommodated within the N+1 slots 602 and does not contact any of the N grounding solder feet 62. In a specific embodiment, there are five grounding solder feet 62, which are sequentially designated as first grounding solder foot 621, second grounding solder foot 622, third grounding solder foot 623, fourth grounding solder foot 624, and fifth grounding solder foot 625. Please refer to... Figure 11 and Figure 12As shown, the grounding weld 62 divides the rear opening 601 into six slots 602, and the six slots 602 are, in sequence, the first slot 6021, the second slot 6022, the third slot 6023, the fourth slot 6024, the fifth slot 6025, and the sixth slot 6026. The first slot 6021 is formed by the first sidewall 611, the first transverse wall 613, the first grounding weld 621, and the second transverse wall 614; the second slot 6022 is formed by the first grounding weld 621, the first transverse wall 613, the second grounding weld 622, and the second transverse wall 614; the third slot 6023 is formed by the second grounding weld 622, the first transverse wall 613, the third grounding weld 623, and the second transverse wall 614; and the third grounding weld 623 and the first transverse wall 614 form the third slot 6026. 613. A fourth slot 6024 is formed between the fourth grounding solder foot 624 and the second transverse wall 614; a fifth slot 6025 is formed between the fourth grounding solder foot 624, the first transverse wall 613, the fifth grounding solder foot 625, and the second transverse wall 614; and a sixth slot 6026 is formed between the fifth grounding solder foot 625, the first transverse wall 613, the second side wall 612, and the second transverse wall 614. The terminal tail is accommodated within the six slots 602 and does not contact any of the five grounding solder feet 62. This ensures the independence of the differential signal and the ground signal.

[0046] Please refer to Figures 1 to 19 As shown, one of the first insulating block 41 and the second insulating block 51 is provided with a groove 5101. The first sidewall 611 and / or the second sidewall 612 are confined within the groove 5101. Please refer to... Figures 17 to 19 In a specific embodiment, grooves 5101 are provided on both the left and right sides of the second insulating block 51. Therefore, in this embodiment, both the first sidewall 611 and the second sidewall 612 are confined within the grooves 5101. This arrangement, where the first sidewall 611 and the second sidewall 612 are bent relative to the first transverse wall 613 and the second transverse wall 614, and both the first sidewall 611 and the second sidewall 612 are confined within the grooves 5101, ensures the stability of the shielding sheet 6's positioning on the second insulating block 51.

[0047] Please refer to Figure 11 , Figure 12 and Figures 17 to 19As shown, one of the first insulating block 41 and the second insulating block 51 is also provided with an insertion hole 5102 communicating with the groove 5101. The first sidewall 611 and the second sidewall 612 each extend with a retaining portion 6121, and a pair of retaining portions 6121 are further inserted into the insertion hole 5102. This further enhances the positioning stability of the shielding sheet 6 on the second insulating block 51.

[0048] Please refer to Figure 3 , Figure 11 , Figure 12 , Figure 13 and Figure 17 As shown, each of the first sidewall 611 and the second sidewall 612 is provided with an elastic lug 6122. The shielding shell 3 contacts a pair of elastic lugs 6122, and the elastic lugs 6122 are pressed against one of the first insulating block 41 and the second insulating block 51 by the shielding shell 3. Therefore, the shielding sheet 6 elastically abuts against the shielding shell 3 through the elastic lugs 6122, realizing the grounding function of electromagnetic interference protection (static discharge protection), that is, the static electricity accumulated on the shielding shell 3 can be conducted away through the elastic lugs 6122 and then through the shielding sheet 6.

[0049] In summary, the main feature of this invention is the inclusion of a shielding plate 6, which is clamped between the first terminal module 4 and the second terminal module 5. More importantly, the shielding plate 6 is provided with multiple grounding solder feet 62. These grounding solder feet 62 are in the same plane as the terminal tails of the differential signal pairs, and are parallel front-to-back and spaced laterally, thus separating the terminal tails of adjacent differential signal pairs. This arrangement of the shielding plate 6 simplifies the forming process, enabling rapid connection (e.g., soldering) between the multiple grounding solder feet 62 and the cable grounding portion, improving soldering efficiency while ensuring soldering quality. It also reduces data interference between differential signal pairs and improves the shielding performance of the electrical connector.

The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model.
