[0044] Please refer to Figure 2 and Figure 4As shown, the terminal module 1 also includes a first insulating block 13, a second insulating block 14, and a third insulating block 15. A first mating portion 112 and a second mating portion 122 are disposed on the second insulating block 14, with at least a portion of their surfaces exposed outside the second insulating block 14. The exposed surfaces of the first mating portion 112 and the second mating portion 122 are used for electrical connection with a mating connector. The second mating portion 122 extends forward relative to the first mating portion 112 by a certain length, and the extended portion of the second mating portion 122 is disposed on the first insulating block 13. A first main body portion 111 and a second main body portion 121 are also disposed on the second insulating block 14. A first tail portion 113 and a second tail portion 123 are disposed on the third insulating block 15. The first insulating block 13, the second insulating block 14, and the third insulating block 15 are all injection molded bodies, which are injection molded together with the signal terminal S, the grounding terminal G, and the grounding structure 2. In other words, the first insulating block 13, the second insulating block 14 and the third insulating block 15 injection mold the signal terminal S, the grounding terminal G, the grounding structure 2 and the cable group 4 into an integral structure to form an electrical connection plug.

[0045] The two first insulating blocks 13 are located on opposite sides of the thickness direction of the grounding structure 2. Please refer to... Figure 3 As shown, the first insulating block 13 includes a plurality of first grooves 131 and a plurality of second grooves 132.

The thickness of the first bent portion 114 is less than the thickness of the first mating portion 112, and the thickness of the second bent portion 124 is less than the thickness of the second mating portion 122. By providing the first bent portion 114 and the second bent portion 124 to extend into the first insulating block 13, and reducing the thickness of the first bent portion 114 and the second bent portion 124, warping of the signal terminal S and the ground terminal G relative to the second insulating block 14 is prevented.

[0047] Please refer to Figure 3 As shown, the grounding structure 2 has a channel 20 that penetrates the entire thickness of the grounding structure 2. The channel 20 is a through-hole for adhesive, which facilitates effective adhesive retention during injection molding of the guide component 3. The channel 20 is at least partially exposed in the first groove 131. Please refer to... Figure 7 and Figure 8As shown, the guide member 3 includes an engaging portion 32 that extends into the channel 20 to achieve an engaging connection between the guide member 3 and the grounding structure 2.

The second bridging portion 222 includes a second hole portion 2221, with a second through hole 220 disposed in the second hole portion 2221. The first hole 2121 extends into the second groove 132 of one of the terminal modules 1 on both sides, and the second hole 2221 extends into the second groove 132 of the other terminal module 1 on both sides, thereby limiting the first hole 2121 and the second hole 2221.

[0049] Please refer to Figure 9As shown, the isolation plate 23 is provided with several fourth through holes 232, which are glue passage holes, facilitating effective glue retention during injection molding of the second insulating block 14. The second insulating block 14 includes protrusions 141, with the upper row of protrusions 141 and the lower row of protrusions 141 extending into different fourth through holes 232, thereby improving the connection stability between the isolation plate 23 and the upper and lower rows of second insulating blocks 14. Please refer to... Figure 10 As shown, the first grounding member 21 includes a fifth through hole 213 through which the protrusion 141 passes, and the second grounding member 22 includes a sixth through hole 223 through which the protrusion 141 passes.

[0050] The guide member 3 is connected to the two terminal modules 1 and the grounding structure 2 via injection molding, and the engaging part 32 is formed in the channel 20. Please refer to Figure 4 and Figure 7 As shown, the guide member 3 includes a body portion 31, an engaging portion 32 connected to the body portion 31, and a hole 320 between the engaging portion 32 and the body portion 31.

The hole wall portion 201 is located within the hole 320, so that the engaging portion 32 and the hole wall portion 201 are in mutual encircling contact to resist the force that causes the guide member 3 and the grounding structure 2 to move away from each other. Please refer to... Figure 10 As shown, the hole wall portion 201 includes a first hole wall portion 2011 of the first grounding member 21, a second hole wall portion 2012 of the second grounding member 22, and a third hole wall portion 2013 of the isolation plate 23.

[0051] Specifically, the occlusal portion 32 is indirectly connected to the body portion 31. Please refer to... Figure 4 and Figure 7 As shown, the guide member 3 includes a first protrusion 33 connected to the body portion 31 and a second protrusion 34 connected to the body portion 31. An engaging portion 32 connects between the two vertically arranged first protrusions 33, forming a hole 320 between the engaging portion 32, the body portion 31, and the two first protrusions 33. The first protrusions 33 extend into the first groove 131 of the first insulating block 13, achieving an engaging connection between the guide member 3 and the first insulating block 13. Please refer to... Figure 7 As shown, the isolation plate 23 includes a side groove 231 recessed inward from the side of the isolation plate 23, and the guide member 3 includes a second protrusion 34 that extends into the side groove 231 to achieve an interlocking connection between the guide member 3 and the isolation plate 23.
