[0003] However, since the copper bar needs to be fixed in the shell by additionally increasing the rear rubber core, and the shell not only needs to be provided with the buckle structure matched with the front rubber core, but also needs to be provided with the buckle structure fixed with the rear rubber core, the shell structure is complex, which not only additionally increases the rear rubber core, but also makes the forming structure of the shell complex, thereby increasing the manufacturing cost of the cable connector assembly and the corresponding assembly process becomes more complex, and since the column size of the transmission bolt is smaller than the hole diameter of the first through hole, when the transmission bolt passes through the first through hole of the copper bar and is connected with the copper bar, the transmission bolt will shake in the first through hole under external force, which will cause unstable current transmission between the transmission bolt and the copper bar, and the transmission of current in the cable connector assembly also needs to pass through the adapter conducting piece, which not only increases the manufacturing cost of the cable connector assembly, but also causes additional current loss when current flows through the adapter conducting piece, and the upper cover needs to be additionally installed on the upper side of the first opening to seal the cable connector assembly, the setting of the upper cover not only makes the assembly of the cable connector assembly more complex, but also further increases the manufacturing cost of the cable connector assembly.

[0047] (1) the insulating shell 1 has the top wall 11 and the bottom wall 12 arranged oppositely, the top wall 11 has a continuously extending outer surface, the first channel 13 is opened upwardly from the bottom wall 12, and the insulating rubber core 2 extends into the first channel 13 from bottom to top and is buckled with the insulating shell 1 in the up-down direction, so that the cable connector assembly 1000 can be sealed without additionally arranging a shielding cover, thus simplifying the installation process and reducing the manufacturing cost; moreover, the insulating shell 1 is arranged with the second channel 15, the insulating rubber core 2 is arranged with the through hole 23 and the transverse hole 24 which is communicated with the through hole 23, the transverse hole 24 is communicated with the second channel 15 in the left-right direction, the wiring member 3 has the fitting section 31 and the wiring section 32, the fitting section 31 has the fixing hole 311 which penetrates from top to bottom, the fitting section 31 extends into the transverse hole 24 from the second channel 15, the fixing hole 311 is aligned with the through hole 23 in the up-down direction, the power terminal 4 is inserted into the through hole 23 from the lower side of the insulating rubber core 2, the fixing column 42 of the power terminal 4 penetrates the fixing hole 311 from bottom to top, and the outer peripheral wall of the fixing column 42 interferes with the hole wall of the fixing hole 311, so that the power terminal 4 and the wiring member 3 can be stably connected, thereby avoiding that the cable connector assembly 1000 is shaken by external force to cause unstable current transmission between the power terminal 4 and the wiring member 3, and additionally arranging no adapter between the power terminal 4 and the wiring member 3, thus not only reducing the current loss but also saving the manufacturing cost; moreover, since the fitting section 31 is fixed with the power terminal 4 through the transverse hole 24, the insulating rubber core 2 and the insulating shell 1 are not only fixed with each other by buckling, but also the insulating rubber core 2 can be fixed in the insulating shell 1 through the wiring member 3, so that the insulating rubber core 2 and the insulating shell 1 can be held with each other by double-layer locking, thus strengthening the fixation of the insulating rubber core 2 and the insulating shell 1, and because the inner wall of the second channel 15 is arranged with the limiting part 154 to limit the wiring section 32, so that the wiring member 3 can be stably fixed in the insulating shell 1, and additionally arranging no fixing member to fix the wiring member 3, thus also reducing the manufacturing cost.

[0048] (2) The matching section 31 is horizontally arranged in a flat plate shape, the fixing hole 311 penetrates the matching section 31 in the up-down direction, the wiring section 32 is in a cylindrical structure, the power cable W2 extends into the wiring section 32 for electrical connection, and the limiting part 154 is distributed on the outer periphery of the wiring section 32 to limit the wiring section 32 in the circumferential direction. The multiple limiting parts 154 can position the wiring piece 3 in the up-down direction and the front-back direction, and the height of the transverse hole 24 in the up-down direction is greater than the height of the matching section 31 and less than the height of the wiring section 32. This can limit the wiring section 32 from entering the transverse hole 24 to the left, thereby limiting the wiring piece 3 in the left-right direction. This can fix and limit the wiring piece 3 in the up-down, front-back, and left-right directions, facilitating the alignment and riveting of the matching section 31 of the wiring piece 3 and the power terminal 4.

[0049] (3) The transverse hole 24 extends from the right side wall of the insulating rubber core 2 to the left and penetrates the left and right walls of the through hole 23. The insulating rubber core 2 has the limiting wall 25 on the left side of the through hole 23. The matching section 31 is inserted into the transverse hole 24 from right to left. The limiting wall 25 stops the left displacement of the matching section 31, and the upper and lower walls of the transverse hole 24 are limited by the matching section 31. The matching section 31 is limited in the up-down and left-right directions, which further ensures that the fixing hole 311 and the fixing column 42 can be riveted and fixed stably and accurately, thereby enabling stable current transmission between the power terminal 4 and the wiring piece 3. The matching section 31 also stops the upper and lower walls of the transverse hole 24 in the up-down direction, which avoids displacement of the insulating rubber core 2 in the up-down direction, and enables better positioning of the insulating rubber core 2 and the insulating shell 1.

[0050] (4) The first side wall 14 is provided with two buckle grooves 141 on one side close to the first channel 13, two buckle grooves 141 are respectively arranged on the front and back of the partition column 152, the insulating shell 1 is respectively provided with a continuously extended second side wall 16 and a third side wall 17 in the front and back direction, the second side wall 16 and the third side wall 17 are respectively extended with the buckle part 18, two buckle parts 18 are respectively located in the sub-channel 153, the left side wall of the seat body part 21 is extended upward with two first buckle arms 212, the first buckle arm 212 is buckled with the buckle groove 141, the second buckle arm 213 is respectively extended along the front and back of the seat body part 21, and the second buckle arm 213 is buckled with the buckle part 18; in this way, the insulating rubber core 2 can be buckled with the insulating shell 1 through the first buckle arm 212 and the second buckle arm 213, thereby avoiding the situation that the power terminal 4 and the wiring part 3 cannot be stably connected due to the deviation of the insulating rubber core 2.

[0051] (5) The second side wall 16 and the third side wall 17 are extended with two limiting parts 154, the top wall 11 is extended downward with two limiting parts 154 respectively located in each sub-channel 153, the front and back walls of the partition column 152 are respectively provided with the limiting part 154, and the limiting part 154 of the partition column 152 is shorter than the other limiting parts 154 in the left and right direction, that is, the right end face of the limiting part 154 of the partition column 152 is closer to the first channel 13 than the right end face of the other limiting parts 154, so that the limiting part 154 of the partition column 152 can provide space for the signal cable W1, so that the signal cable W1 can smoothly extend out of the insulating shell 1 from the second channel 15, and the limiting part 154 of the second side wall 16, the limiting part 154 of the third side wall 17, and the limiting part 154 of the partition column 152 are flush with each other in the front and back direction, the limiting part 154 limits and stops each wiring part 3 in the front and back direction, so that the wiring part 3 is uniformly stressed in the front and back direction; in this way, the problem that the wiring part 3 is skewed due to the asymmetric stress position of the wiring part 3 in the front and back direction is avoided.

[0052] (6) The first waterproof ring 26 is installed between the outer peripheral surface of the insulating rubber core 2 and the inner peripheral surface of the insulating shell 1, and the second waterproof ring 27 is further provided on the outer peripheral surface of the insulating rubber core 2 below the first waterproof ring 26. The first waterproof ring 26 is located below the transverse hole 24 to seal the gap between the insulating rubber core 2 and the insulating shell 1, thereby preventing water vapor or dust from entering the transverse hole 24 from the gap between the insulating rubber core 2 and the insulating shell 1, and further preventing the wiring member 3 and the power terminal 4 from being contacted by water vapor or dust, which affects the current transmission between the power terminal 4 and the wiring member 3. Thus, the entire cable connector assembly 1000 has good internal sealing performance, and the second waterproof ring 27 is exposed on the outside of the insulating shell 1 to abut against the mating shell 1' of the mating connector 2000', so that the cable connector assembly 1000 and the mating connector 2000' are sealed during mating, thereby preventing water vapor or dust from entering the cable connector assembly 1000 from the mating position of the two connectors and affecting the transmission of current and signal.

[0053] (7) The waterproof plug 6 is located on the side of the second channel 15 away from the first channel 13, and the waterproof plug 6 abuts and seals with the inner peripheral surface of the second channel 15. The end surface of the partition 152 away from the first channel 13 is used to limit the left displacement of the waterproof plug 6. The waterproof plug 6 is further provided with the cover 7 fixedly clamped with the insulating shell 1 on the right side of the waterproof plug 6. The cover 7 stops the waterproof plug 6 from being separated from the second channel 15 to the right, so that the waterproof plug 6 is sealed on the right side of the second channel 15, thereby preventing water vapor or dust from entering the second channel 15 from the right side of the second channel 15, and preventing the power cable W2 and the wiring member 3 from being contacted by water vapor or dust, which affects the power transmission between the power cable W2 and the wiring member 3. Moreover, the waterproof plug 6 has a plurality of signal through holes 61 and power through holes 62 located on the front and back sides of the plurality of signal through holes 61, which are penetrated in the left-right direction. The plurality of signal cables W1 are connected to the upper ends of the plurality of signal terminals 5, and the two power cables W2 are connected to the wiring segments 32 of the two wiring members 3. The plurality of signal cables W1 pass through the plurality of signal through holes 61, and the two power cables W2 pass through the two power through holes 62, so as to prevent the signal cables W1 from being stopped by the partition 152 and being unable to smoothly extend out of the insulating shell 1. Moreover, the plurality of signal cables W1 are arranged between the two power cables W2, which can save space and facilitate the bundling and fixing of all cables.

[0054] (8) The butt joint surface 214 of the insulating rubber core 2 is concavely provided with the anti-fumble groove 215, which is in a convex shape. Thus, the anti-fumble groove 215 not only prevents the misplug of the docking connector 2000', but also avoids the docking terminal 2' of the docking connector 2000' from being obliquely inserted into the terminal hole 43 of the power terminal 4, so that the docking terminal 2' scratches or damages the elastic terminal 44 in the terminal hole 43, and also avoids the problem that the plurality of signal terminals 5 cannot be aligned with the docking terminal 2' of the docking connector 2000' to form electrical connection.
