The signal terminal module includes a second insulating block and a plurality of second signal terminals fixed on the second insulating block. The first signal terminal and the second signal terminal together form a plurality of differential signal pairs. The plurality of differential signal pairs have a plurality of terminal tails located in the same plane. The shield is a one-piece structure of metal material. The shield includes a base, a plurality of grounding contacts and a plurality of grounding solders. The base is clamped and positioned between the first insulating block and the second insulating block. The grounding solders and the grounding contacts extend in opposite directions from the front and rear ends of the base. The plurality of grounding solders are arranged in the same plane and separate the terminal tails of two adjacent sets of differential signal pairs.

[0006] As a further improvement to this invention, one of the first insulating block and the second insulating block is provided with a row of multiple protrusions, and any one of the grounding solder feet is clamped between two adjacent protrusions.

[0007] As a further improvement to the present invention, the second insulating block is provided with a first base, each of the protrusions protruding upward from the first base and the plurality of protrusions being connected by the first base. The protrusion has an upper mounting surface facing away from the first base and a root portion connected to the first base. The height of each protrusion from the upper mounting surface to the root portion is equal to the thickness of the grounding solder foot.

[0008] As a further improvement to the present invention, the terminal tail includes a first terminal tail of the first signal terminal and a second terminal tail of the second signal terminal. The first terminal tail is assembled into the boss, the second terminal tail is disposed in the boss, and the first terminal tail and the second terminal tail are exposed on the upper assembly surface.

[0009] As a further improvement to the present invention, the first insulating block includes a plurality of first blocks, a plurality of the tails of the first terminals are divided into arrays, each array of the tails of the first terminals is held by one of the first blocks, and the second insulating block has a receiving groove on a portion of the protrusion, with each of the first blocks correspondingly confined within the receiving groove.

[0010] As a further improvement to the present invention, the tail of the shielding plate includes a first sidewall and a second sidewall arranged opposite to each other in the left-right direction, and a first transverse wall and a second transverse wall arranged opposite to each other in the front-back direction. The first sidewall and the second sidewall are bent relative to the first transverse wall and the second transverse wall. The first sidewall, the first transverse wall, the second sidewall and the second transverse wall are connected end to end to form a rear opening. The first transverse wall and the second transverse wall each have an inner wall surface facing the rear opening. One end of each grounding solder foot is connected to the inner wall surface of the first transverse wall and the other end is connected to the inner wall surface of the second transverse wall.

[0011] As a further improvement to this invention, the grounding solder pins are N, and the rear opening is divided into N+1 slots. The tail of the terminal is accommodated in the N+1 slots and does not contact any of the N grounding solder pins.

The shielding sheet has multiple grounding solder pads that are parallel to the terminal ends of the differential signal pairs in the same plane and spaced apart horizontally. This design separates the terminal ends of adjacent differential signal pairs. This shielding sheet configuration simplifies the molding process. The multiple grounding solder pads allow for quick connection to the cable grounding point, 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. Simple Explanation of the Diagram

[0020] Referring to Figures 1 to 19, this invention discloses an electrical connector 100, which includes an insulating body 1, a terminal module 2 at least partially disposed within the insulating body 1, and a shielding shell 3 covering the insulating body 1. In this 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 in this embodiment, the mating direction of the electrical connector 100 mating with the mating connector is the front-back direction in Figure 1, that is, the mating direction is defined as the front-back direction. Referring to Figure 1, the electrical connector 100 also has a left-right direction and a top-bottom direction, and the top-bottom 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.

[0021] Referring to Figures 1 to 6, the electrical connector 100 includes an insulating body 1, a terminal module 2, and a shielding shell 3. The terminal module 2 is at least partially disposed within the insulating body 1, and the shielding shell 3 is at least partially sleeved 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 a plurality of terminal tails located in the same plane. In a specific embodiment, there are six groups of differential signal pairs. Differential transmission is a signal transmission technology that differs from the traditional method of using one signal line and one ground line (single-ended signal). Differential transmission transmits signals on both (or other even-numbered) lines, with equal amplitudes and opposite phases. The signals transmitted on these two (or other even-numbered) lines are called differential signals. Differential signal transmission has at least two advantages: 1. Strong anti-interference capability. Interference noise is generally applied equally and simultaneously to both (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, the electromagnetic interference to the outside world is small.

[0022] Please refer to Figures 11 and 12. The shielding plate 6 is a one-piece structure made of metal material. In a specific embodiment, the shielding plate 6 is made by stamping metal material; in other embodiments, it can also be made by laser cutting or other methods. The shielding plate 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 ends of two adjacent sets of differential signal pairs. The plurality of grounding solder feet 62 constitute the ground wire. The shielding plate 6 is configured to have a plurality of grounding solder feet 62, which 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 groups in the specific embodiment), and improves the shielding performance of the electrical connector 100.

[0023] Please refer to Figures 9, 13, and 15 to 17. 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 located on the first insulating block 41. Each grounding solder foot 62 is held between two adjacent protrusions 511. The protrusions 511 ensure that when the shielding sheet 6 is held and positioned between the first insulating block 41 and the second insulating block 51 in the vertical direction, the positioning of each grounding solder foot 62 in the horizontal direction prevents the shielding sheet 6 from easily wobbling in the horizontal direction.

[0024] Please refer to Figures 9, 10 and 19. The second insulating block 51 is provided with a first base 510. Each boss 511 protrudes upward from the first base 510 and the plurality of bosses 511 are connected by the first base 510. The 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 plate 6 is positioned on the second insulating block 51, it ensures that each of the grounding solder feet 62 is flush with the upper assembly surface 5111. In other words, the upper assembly surface 5111 is the same plane where the tails of the multiple terminals of the multiple differential signal pairs are located, and it is exposed at the tail end of the first insulating block 41, ensuring the visibility of the plane and facilitating subsequent soldering operations with the cable.

[0025] Please refer to Figures 1 to 19. In this specific embodiment, since the electrical connector 100 is an HDMI connector, there are five grounding solder pads 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 this 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 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 inserted into the protrusions 511 provided on the second insulating block 51 in an assembled manner. Of course, the first signal terminal 42 also includes seven first terminal heads 421, and the second signal terminal 52 also includes seven second terminal heads 521. The electrical connector 100 has a front insertion interface 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.

[0026] Please refer to Figures 7 to 10 and Figures 13 to 17. The first insulating block 41 includes a plurality of first blocks 410, and the plurality of first terminal tails 422 are divided into groups, with each group 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 being held by one first block 410, and the seventh first terminal tail 422 being held by a single first block 410. The second insulating block 51 has a receiving groove 5110 on a portion of the protrusion 511, and the first blocks 410 are correspondingly confined within the receiving groove 5110. The alignment and cooperation between the first blocks 410 and the receiving groove 5110 ensures the stability and accuracy of the positioning of the first terminal tail 422 within the protrusion 511.

[0027] Please refer to Figures 11 to 19. The rear portion of the shielding plate 6, away from the front connector 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. The dashed arrow in Figure 11 indicates the width of the rear opening 601 in the left-right direction. It can be seen that, in the specific embodiment of this 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 pad 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 allows the grounding solder pads 62 to be parallel front-to-back and spaced left-to-right in the same plane, facilitating the separation of the tails of the plurality of terminals of the differential signal pair if differential separation is required.

[0028] Referring to Figure 11, 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. Referring to Figures 11 and 12, the grounding solder feet 62 divide the rear opening 601 into six slots 602, which are sequentially designated as first slot 6021, second slot 6022, third slot 6023, fourth slot 6024, fifth slot 6025, and sixth slot 6026. The first sidewall 611, the first transverse wall 613, the first grounding weld 621, and the second transverse wall 614 form a first slot 6021; the first grounding weld 621, the first transverse wall 613, the second grounding weld 622, and the second transverse wall 614 form a second slot 6022; the second grounding weld 622, the first transverse wall 613, the third grounding weld 623, and the second transverse wall 614 form a third slot 6023; the third grounding weld 623, the first transverse wall... 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; 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 tail of the terminal 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.

[0029] Please refer to Figures 1 to 19. 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 is confined within the groove 5101. Referring to Figures 17 to 19, in a specific embodiment, the groove 5101 is provided on both the left and right sides of the second insulating block 51. Therefore, in a specific embodiment, both the first sidewall 611 and the second sidewall 612 are confined within the groove 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 groove 5101, ensures the stability of the shielding sheet 6's positioning on the second insulating block 51.

[0030] Please refer to Figures 11, 12, and 17 to 19. One of the first insulating block 41 and the second insulating block 51 is further provided with an insertion hole 5102 communicating with the groove 5101. Each of the first sidewall 611 and the second sidewall 612 extends 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.

[0031] Please refer to Figures 3, 11, 12, 13, and 17. Each of the first sidewall 611 and the second sidewall 612 is provided with an elastic lug 6122. The shielding housing 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 housing 3. Therefore, the shielding plate 6 achieves the grounding function of electromagnetic interference prevention (static discharge prevention) through the elastic lugs 6122 and the shielding housing 3, meaning that static electricity accumulated on the shielding housing 3 can be conducted away through the elastic lugs 6122 and then through the shielding plate 6.

[0032] In summary, this invention mainly involves setting up a shielding plate 6 and clamping it between the first terminal module 4 and the second terminal module 5. More importantly, the shielding plate 6 is provided with a plurality of grounding solder feet 62. These grounding solder feet 62 are in the same plane as the terminal tails of the differential signal pairs. The plurality of grounding solder feet 62 are parallel front to back and spaced left to right, used to separate the terminal tails of adjacent sets of differential signal pairs. This arrangement of the shielding plate 6 in this invention simplifies the forming process, enables rapid connection (e.g., soldering) between the plurality of grounding solder feet 62 and the cable grounding part, improves soldering efficiency, ensures soldering quality, reduces data interference between differential signal pairs, and improves the shielding performance of the electrical connector 100 of this invention.
