Specifically, the first housing 55 includes a generally rectangular base 551 and a cylindrical portion 552 extending from the base 551. The cable 53 passes through the first housing 55 from the base 551 and the cylindrical portion 552. Furthermore, to improve the grounding shielding effect, those skilled in the art will understand that the first housings 55 of the two terminal modules 5 can also be connected by a metal sheet.

[0113] In one embodiment of the invention, the first support 56 is made of an insulating material. The first receiving shell 55 mates with the first support 56. The first sealing member 54 abuts against the rear end of the first support 56. The cable 53 passes through the first receiving shell 55, the first support 56, and the first sealing member 54. The first support 56 has an opening 561 through which the cable 53 passes and a plurality of locking holes 562 located around the opening 561.

In the illustrated embodiment of the invention, there are four locking holes 562, each located at one of the four outer corners of the opening 561.

[0114] Specifically, the first sealing member 54 is tightly fitted onto the insulating sheath 533 to improve the sealing performance of the cable 53. Specifically, the first sealing member 54 includes a rectangular body portion 541, a plurality of extending protrusions 542 integrally extending from the body portion 541, and a first through hole 543 penetrating the body portion 541. The body portion 541 also has a plurality of first through holes 5411 penetrating the body portion 541. The insulating sheath 533 of the cable 53 passes through the first through holes 543 and exits the first sealing member 54. In the embodiment illustrated in the present invention, there are four first through holes 5411, each located at one of the four corners outside the first through hole 543. Correspondingly, the first through holes 5411 and the locking hole 562 are aligned along the first direction A1-A1.

[0115] Please combine Figure 27 as well as Figure 28 As shown in the illustrated embodiment of the present invention, the electrical connector 100 further includes a second bracket 71 that cooperates with the first bracket 56, a second receiving shell 72 that houses the second bracket 71, a second sealing member 73 that is sleeved on the second receiving shell 72, and an end cap 74 that is locked to the mounting housing 1.

The protrusions 712 and the claws 713 are respectively located on both sides of the plate portion 711. The plate portion 711 has a second through hole 7111 corresponding to the first through hole 543. The protrusions 712 are used to insert into the first through hole 5411 and the locking hole 562. The protrusions 712 are configured to cooperate with the first bracket 56 to limit the first sealing member 54 and reduce the risk of loosening. In the embodiment illustrated in the present invention, the protrusions 712 have a hook portion 7121 located at their free end, and the hook portion 7121 has a slot 7122, so that the hook portion 7121 has a certain elastic deformation capability. When the hook 7121 passes through the locking hole 562, the hook 7121 releases its elastic force, allowing the hook 7121 to lock with the first bracket 56.

[0117] In the embodiment illustrated in the present invention, there are several claws 713 arranged at circumferential intervals, so that each claw 713 has a certain elastic deformation capability. In the embodiment illustrated in the present invention, the claw 713 forms a generally conical protrusion 714, and the diameter of the protrusion 714 is smaller closer to its free end, so as to facilitate its cooperation with the end cap 74.

[0118] The second receiving shell 72 is provided with an annular positioning groove 721 for holding the second sealing member 73. The second sealing member 73 is a sealing ring and is clamped between the second receiving shell 72 and the retaining part 13 to achieve a sealing function. The embodiment illustrated in the present invention uses the first sealing member 54 (e.g., an inner sealing member) and the second sealing member 73 (e.g., an outer sealing member) to achieve a double sealing function, thereby improving the waterproof, dustproof and other performance of the electrical connector 100. Specifically, please refer to... Figure 35 As shown, the first seal 54 is sealed between the cable 53 and the second housing 72, and the second seal 73 is sealed between the mounting housing 1 and the second housing 72.

[0119] The end cap 74 includes a base plate portion 741, a locking tab 742 protruding from the base plate portion 741 along the first direction A1-A1 to one side, and a sleeve portion 743 protruding from the base plate portion 741 along the first direction A1-A1 to the other side. The base plate portion 741 has a third through hole 7411 corresponding to the second through hole 7111, allowing the cable 53 to pass through. Furthermore, the base plate portion 741 also has a mounting hole 7412 penetrating the base plate portion 741, and the extension tab 542 is at least partially inserted into the mounting hole 7412. In one embodiment of the invention, the extension tab 542 is inserted into the mounting hole 7412 and protrudes from the base plate portion 741 to improve assembly and sealing performance. The locking tab 742 is positioned in the positioning groove 133, and the locking tab 742 has a retaining hole 7421 that engages with the locking tab 134. The sleeve portion 743 is generally conical, and its diameter decreases towards its free end. The sleeve portion 743 is fitted onto the protrusion 714 and abuts against the claw 713 to improve the engagement force.

[0120] The terminal cover 57 is mounted on the insulating body 3 and corresponds to the receiving groove 31. In one embodiment of the invention, the terminal cover 57 is fixed to the insulating body 3. The terminal cover 57 is provided with a locking arm 571 that locks into the insulating body 3. In one embodiment of the invention, the terminal cover 57 is made of insulating material. The terminal cover 57 can shield the first contact portion 511 and the second contact portion 512 of the conductive terminal 51, thereby reducing the risk of electric shock due to accidental contact with the first contact portion 511 and / or the second contact portion 512.

[0121] Specifically, in one embodiment of the present invention, the terminal cover 57 includes a slot 570 corresponding to and communicating with the interval space 510. Furthermore, the terminal cover 57 also has a mounting slot 572 for mounting the sliding terminal locking block 58, which is slidable relative to the terminal cover 57 between a locked position and an unlocked position, and does not detach from the terminal cover 57 during sliding. The sliding terminal locking block 58 protrudes into the docking cavity 102.

[0122] Please combine Figure 35 as well as Figure 36 As shown in the illustrated embodiment of the present invention, the electrical connector 100 further includes a fixing terminal locking block 59 mounted on the insulating body 3. The fixing terminal locking block 59 cannot slide relative to the insulating body 3. When the terminal module 5 is installed in place, the fixing terminal locking block 59 can provide a certain degree of fixation for the terminal module 5.

[0123] Please combine Figure 35 as well as Figure 36 As shown, during assembly, firstly, the connecting piece 52 is fixed to the conductive terminal 51, and then the cable 53 is connected to the conductive terminal 51 (e.g., by welding). Then, the first housing 55, the first bracket 56, the first seal 54, the second bracket 71, the second housing 72, the second seal 73, and the end cap 74 are installed on the cable 53. Next, the terminal module 5 is installed in the receiving groove 31 of the insulating body 3. When installed in place, the first locking spring 5213 and the second locking spring 5223 return from a compressed state to a non-compressed state. At this time, a "click" sound can be heard, and the first locking portion 5213a of the first locking spring 5213... The second locking part 5223a of the second locking spring 5223 is locked to the insulating body 3, which serves as a "first lock" to prevent the terminal module 5 from detaching from the insulating body 3. Then, the metal shielding shell 4 is wrapped around the insulating body 3. Then, the terminal module 5, the insulating body 3 and the metal shielding shell 4 are inserted into the mounting cavity 101 along the first direction A1-A1. After installation, the sliding terminal locking block 58 is slid along the second direction A2-A2 so that the sliding terminal locking block 58 is engaged in the first locking groove 5111a and the second locking groove 5121a, which serves as a "second lock" to prevent the terminal module 5 from detaching from the mounting shell 1.

[0124] During unlocking, tools are used to press the first locking spring 5213 and the second locking spring 5223, causing the first locking part 5213a of the first locking spring 5213 and the second locking part 5223a of the second locking spring 5223 to disengage from the locking of the insulating body 3, thereby unlocking the "first lock"; then, the sliding terminal locking block 58 is slid, causing the sliding terminal locking block 58 to disengage from the first locking groove 5111a and the second locking groove 5121a, thereby unlocking the "second lock"; then, a pulling force is applied to the terminal module 5, which can disassemble the terminal module 5.
