[0039] In an embodiment of the present utility model, the conductive terminals 12 are assembled and fixed on the insulating body 11. Of course, in other embodiments of the present utility model, the conductive terminals 12 can also be fixed on the insulating body 11 by insert molding.

[0040] Please refer to Figures 6 to 10 As shown, the insulating body 11 is provided with a first mounting surface 110, an external thread portion 111 close to the first mounting surface 110, and a second mounting surface 112 opposite to the first mounting surface 110. The conductive terminal 12 includes a cable connection portion 12a protruding from the first mounting surface 110 along the axial direction of the cable connector 100 and a docking portion 12b protruding from the second mounting surface 112 along the axial direction of the cable connector 100. In the illustrated embodiment of the present utility model, the plurality of conductive terminals 12 are generally circumferentially spaced apart on the insulating body 11. Each conductive terminal 12 includes a mounting jack 120.

[0041] The cylinder 13 includes a cylindrical portion 131 and a mounting portion 132 connected to the cylindrical portion 131. The cylindrical portion 131 is provided with an inner cavity 1310, and the first mounting surface 110 is exposed to the inner cavity 1310. The conductive terminal 12 at least partially protrudes into the inner cavity 1310. The mounting portion 132 is provided with an internal thread portion 1321. The cylinder 13 is connected to the insulating body 11 by a thread. Specifically, the internal thread portion 1321 of the cylinder 13 cooperates with the external thread portion 111 of the insulating body 11.

[0042] In an embodiment of the present utility model, the cylinder 13 is a metal cylinder, which is made of a metal material to perform a certain degree of external shielding on the conductive terminal 12, thereby improving the quality of signal transmission. Of course, the metal cylinder can also increase the structural strength of the cable connector 100.

[0043] Each cable 3 is provided with a core 31, and the core 31 is welded and fixed to the corresponding conductive terminal 12. In the illustrated embodiment of the present utility model, the core 31 of the cable 3 is inserted into the mounting jack 120 of the conductive terminal 12 and fixed by welding.

[0044] The terminal isolation block 2 and the insulating body 11 are two separate parts. The terminal isolation block 2 has a shape adapted to the corresponding surface profile of the conductive terminal 12. The terminal isolation block 2 is at least partially inserted into the space between the plurality of conductive terminals 12 along the axial direction of the cable connector 100. The terminal isolation block 2 is located on one side of the first mounting surface 110 and protrudes from the first mounting surface 110. The terminal isolation block 2 includes a base portion 21 and a plurality of isolation walls 22. In the illustrated embodiment of the present invention, the plurality of isolation walls 22 extend integrally from the base portion 21, and the plurality of isolation walls 22 are radially located around the base portion 21. The base portion 21 is provided with a central mounting hole 210 to receive the corresponding conductive terminal 12.

[0045] The terminal isolation block 2 includes an isolation groove 23 located between two adjacent isolation walls 22, wherein the conductive terminal 12 is located in the corresponding isolation groove 23, so that at least two adjacent conductive terminals 12 are separated by the isolation wall 22 located between the two conductive terminals 12.

[0046] In the illustrated embodiment of the present invention, each isolation wall 22 protrudes radially of the cable connector 100 beyond the conductive terminal 12 isolated by the isolation wall 22. In an embodiment of the present invention, the height by which the isolation wall 22 protrudes beyond the corresponding conductive terminal 12 is 0.5 mm. Those skilled in the art can understand that by protruding the isolation wall 22 beyond the corresponding conductive terminal 12, the isolation wall 22 can play a certain role in hindering soldering, which is beneficial to reducing the risk of terminal short circuit. At the same time, those skilled in the art can also understand that the height by which the isolation wall 22 protrudes beyond the corresponding conductive terminal 12 should not be too high, otherwise the isolation wall 22 is more likely to be touched by the soldering gun, resulting in other defects.

[0047] Please refer to Figure 7 and Figure 8 As shown, in the illustrated embodiment of the present invention, the isolation groove 23 is in the shape of a flared opening, wherein the conductive terminal 12 is tightly clamped in the corresponding isolation groove 23. Specifically, the isolation wall 22 is provided with an outer side surface 221, the conductive terminal 12 has a cylindrical outer surface 121, and the outer side surface 221 is tangent to the outer surface 121. In the illustrated embodiment of the present invention, there is a gap 122 between at least one group of two adjacent conductive terminals 12, and the isolation walls 22 inserted into the gap 122 are in close contact with the two adjacent conductive terminals 12 respectively. With such a setting, through the elasticity of the conductive terminal 12, the isolation wall 22 is tightly clamped, thereby preventing the terminal isolation block 2 from falling off.

[0048] Those skilled in the art can understand that by tightly clamping the conductive terminal 12 in the corresponding isolation groove 23, the conductive terminal 12 can be positioned, which is conducive to improving production efficiency and yield.

[0049] In the illustrated embodiment of the present invention, the terminal isolation block 2 is an insulating isolation block made of insulating material. Correspondingly, the isolation wall 22 is also made of insulating material to avoid terminal short - circuit while separating the conductive terminals 12.

[0050] Please refer to Figure 8 and Figure 9 As shown, as a further improvement of the present invention, the cable connector 100 further includes a metal sheet 14. The metal sheet 14 is inserted between at least one group of two adjacent conductive terminals 12, and the metal sheet 14 abuts against the two conductive terminals 12 in this group. Those skilled in the art can understand that in some application scenarios, the two conductive terminals 12 on both sides of the metal sheet 14 may be power terminals (positive power terminal or negative power terminal). At this time, connecting the two conductive terminals 12 on both sides of the metal sheet 14 through the metal sheet 14 is conducive to improving the power transmission ability. Of course, in some other application scenarios, the two conductive terminals 12 on both sides of the metal sheet 14 may be ground terminals. At this time, connecting the two ground terminals on both sides of the metal sheet 14 through the metal sheet 14 is conducive to improving the grounding effect.

[0051] Compared with the prior art, the connector joint 1 of the present invention may be a purchased part. By providing the terminal isolation block 2, the terminal isolation block 2 is at least partially inserted into the space between the plurality of conductive terminals 12 along the axial direction of the cable connector 100. The terminal isolation block 2 is located on one side of the first mounting surface 110. The terminal isolation block 2 includes a plurality of isolation walls 22 and isolation grooves 23 located between adjacent two isolation walls 22, wherein the conductive terminals 12 are located in the corresponding isolation grooves 23, so that at least two adjacent conductive terminals 12 are separated by the isolation wall 22 located between these two conductive terminals 12. By providing the isolation wall 22, adjacent conductive terminals 12 can be well separated. Thus, when the conductive terminals 12 are welded to the cable 3, the welding accuracy can be improved and the welding efficiency can be increased. In addition, the isolation wall 22 can play a certain role in blocking the solder, preventing the solder from adhering to the conductive terminals 12 that should not be adhered to, thereby reducing the short - circuit risk and improving the yield. In addition, by providing the terminal isolation block 2, the isolation wall 22 itself can separate the solder joints, thereby reducing the control requirements for the solder joints, so that even if the solder joints are slightly larger or have slightly tin tips, they are no longer risk items.

The understanding of the present utility model should be based on those skilled in the relevant technical field.
