[0040] When used herein, the singular forms "a", "an", and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0041] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, a cable connector includes a mounting base 1, a connecting terminal 2 and a connecting head 3, the mounting base 1 is provided with at least one; the connecting terminal 2 is arranged in the mounting base 1, the connecting terminal 2 includes a first connecting member 21 and a second connecting member 22, the first connecting member 21 includes a pin rod 211, and the pin rod 211 is provided with an annular protrusion 212; the second connecting member 22 includes a connecting rod 221, and one end of the connecting rod 221 is provided with a connecting protrusion 222; one end of the connecting head 3 is provided with an annular groove 31, the annular protrusion 212 is rotatably connected to the annular groove 31, and the other end of the connecting head 3 is provided with a connecting groove 32, and the connecting protrusion 222 is snapped into the connecting groove 32.

[0042] In this embodiment, a mounting base 1 is used to secure each connecting terminal 2, thereby reducing the vibration frequency of the connecting terminal 2. An annular protrusion 212 is provided on the pin 211, and an annular groove 31 is provided on the connector 3. The annular protrusion 212 is rotatably connected to the annular groove 31. The rotatable connection between the pin 211 and the connector 3 effectively eliminates damage to the cable connector caused by the rotation of the two cable sections. This overcomes the problem of vibration and slight rotation of the existing cable during actual operation. Over time, this can damage the cable connector and the cable connection end, ultimately causing the cable to detach from the cable connector.

[0043] See also Figure 6 、 Figure 7 and Figure 9 As shown, in some embodiments, the connecting protrusion 222 is set in a hemispherical shape, and the cross-section of the hemispherical connecting protrusion 222 is a superior arcuate shape. When the connecting protrusion 222 is engaged with the connecting groove 32, the diameter of the connecting protrusion 222 inside the connecting groove 32 is larger than the diameter of the connecting protrusion 222 at the outlet of the connecting groove 32, thereby making the connecting protrusion 222 firmly engaged with the connecting groove 32.

[0044] In this embodiment, the connecting protrusion 222 is hemispherical, and its cross-section is superiorly arcuate. That is, the center of the hemispherical connecting protrusion 222 is located within the connecting groove 32. When the connecting protrusion 222 is in the installed position, the connecting protrusion 222 is locked into the connecting groove 32 because the outlet diameter of the connecting groove 32 is smaller than the diameter of the hemispherical connecting protrusion 222.

[0045] See also Figure 6 , and 7, Figure 9 and Figure 10 As shown, in some embodiments, a connection limit member 4 is further included, and the connection limit member 4 includes a connection limit block 41. The connection limit block 41 is arranged in the connection groove 32 and abuts against the hemispherical connection protrusion 222. The connection limit block 41 is configured as follows: when the connection limit block 41 is arranged in the connection groove 32 and the connection limit block 41 abuts against the hemispherical connection protrusion 222, the hemispherical connection protrusion 222 is clamped in the connection groove 32; when the connection limit block 41 is disengaged from the connection groove 32, the hemispherical connection protrusion 222 is disengaged from the connection groove 32.

[0046] In this embodiment, since the connecting protrusion 222 needs to be engaged with the connecting groove 32, while the connecting groove 32 is spherical, the connecting protrusion 222 is hemispherical. Therefore, a connecting stopper 41 is provided to engage the connecting protrusion 222 within the connecting groove 32. To further reduce vibration between the connecting protrusion 222 and the connecting groove 32, the connecting stopper 41 is made of a flexible material, such as rubber, which falls within the scope of protection of this application.

[0047] In some embodiments, a mounting cavity 53 is provided in the connector 3, and the connection limit member 4 also includes an elastic support member 42, and the elastic support member 42 includes a sliding block 421 and an elastic member 422, and the sliding block 421 is slidably connected to the mounting cavity 53; one end of the elastic member 422 abuts against the mounting cavity 53, and the other end abuts against the sliding block 421, and the elastic member 422 is configured as follows: when the mounting seat 1 is installed, the sliding block 421 abuts against the mounting seat 1, and the elastic member 422 is in a compressed position. At this time, the sliding block 421 abuts against the connection limit block 41; when the mounting seat 1 is disassembled, the sliding block 421 disengages from the mounting seat 1, the elastic member 422 releases elastic potential energy, and the sliding block 421 disengages from the connection limit block 41.

[0048] In this embodiment, when in the installed position, the mounting base 1 presses against the sliding block 421, and the elastic member 422 is in a compressed position, storing energy in the elastic member 422. When in the disassembly position, the sliding block 421 is disengaged from the mounting base 1, and the elastic member 422 releases its elastic potential energy, thereby disengaging the sliding block 421 from the connection limit block 41, thereby facilitating the disassembly of the connection limit block 41.

[0049] In some embodiments, the elastic member 422 is one of a spring, rubber, and a thermoplastic elastomer.

[0050] See also Figure 4 and Figure 5 As shown, in some embodiments, a rotation limiter 5 is further included, and the rotation limiter 5 includes a rotation block 51 and a rotation snap ring 52, and the rotation block 51 is fixed on the pin rod 211; the rotation snap ring 52 is fixed on the connector 3, and the rotation snap ring 52 is sleeved on the outside of the rotation block 51, for limiting the rotation range of the rotation block 51.

[0051] In this embodiment, the cable and the cable connector may rotate relative to each other, but excessive rotation may still damage the cable and the cable connector. Therefore, by providing a rotating block 51 and a rotating ring 52, the cable and the cable connector are kept in a small rotation range, thereby reducing damage to the cable and the cable connector.

[0052] See also Figure 1 and Figure 2 As shown, in some embodiments, the mounting base 1 includes a first base body 11 and a second base body 12 , the first base body 11 is clamped on one side of the connecting terminal 2 ; the second base body 12 is clamped on the other side of the connecting terminal 2 .

[0053] In some embodiments, the mounting base 1 further includes an insert block 13, a connecting block 14 and a base body bolt 16, the insert block 13 being arranged on one side of the first base body 11 and the second base body 12; the connecting block 14 being arranged on the other side of the first base body 11 and the second base body 12, the insert block 13 on the first base body 11 being connected to the connecting block 14, and the insert block 13 on the second base body 12 being connected to the connecting block 14; a base body hole 15 is provided on both the insert block 13 and the connecting block 14; the base body bolt 16 is arranged in the base body hole 15 for fixing the first base body 11 and the second base body 12.

[0054] In this embodiment, because multiple cables need to be connected in the prior art, insert blocks 13 and connector blocks 14 are provided on the first and second base bodies 11, 12. This allows multiple first and second base bodies 11, 12 to be spliced ​​together, thereby enhancing the stability of the multiple cable connections.

[0055] See also Figure 6 and Figure 7 As shown, in some embodiments, the second connecting member 22 further includes a cable sleeve 223, a first latch 224 and a second latch 225, the cable sleeve 223 is arranged at one end of the connecting rod 221 away from the connecting protrusion 222; the first latch 224 is arranged on one side of the inner cavity of the cable sleeve 223; the second latch 225 is arranged on the other side of the inner cavity of the cable sleeve 223, and the second latch 225 is arranged in a one-to-one correspondence with the first latch 224, so as to engage the second latch 225 with the first latch 224 after the cable sleeve 223 is squeezed, so as to fix the cable in the cable sleeve 223.

[0056] In this embodiment, the conventional method is to directly use the cable clamp 223 to clamp the cable. However, the present application provides a first clamping tooth 224 on one side of the inner cavity of the cable clamp 223, and a second clamping tooth 225 on the other side of the inner cavity of the cable clamp 223. The first clamping teeth 224 are arranged one-to-one with the second clamping teeth 225, that is, they are arranged in a spaced-to-interlocking manner. The provision of the first clamping teeth 224 and the second clamping teeth 225 provides a more stable cable connection.

[0057] In some embodiments, the first connecting member 21 further includes a connecting screw hole 213, a connecting bolt 214 and a mounting gasket 215. The connecting screw hole 213 is located in the middle of the pin rod 211 for connecting the cable; the connecting bolt 214 is threadedly connected to the connecting screw hole 213; the mounting gasket 215 is located between the connecting screw hole 213 and the connecting bolt 214 for fixing the cable on the pin rod 211.

[0058] In this embodiment, the conventional method is to directly connect the cable to the connecting screw hole 213. However, the mounting washer 215 of the present application is provided between the connecting screw hole 213 and the connecting bolt 214, thereby fixing the cable to the pin rod 211 more firmly.

[0059] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
