[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please see attached Figure 1-4 In the embodiment of the utility model, a pulling-resistant vehicle data cable comprises an interface 1, a cable housing 2 is fixed to one side of the interface 1, and a pulling-resistant component 3 is fixed to one side of the cable housing 2;

[0029] The tensile assembly 3 includes a connecting block 31, a circular card slot 33 and a limit card slot 37 are provided in the connecting block 31, the circular card slot 33 and the limit card slot 37 are connected, the connecting block 31 is connected to the data line 5, a protective cover 4 is sleeved between the connecting block 31 and the data line 5, a plurality of limit card blocks 34 are fixed to one side of the protective cover 4 located in the connecting block 31, a circular card block 36 is fixed to one side of the protective cover 4, the circular card block 36 cooperates with the circular card slot 33, and a plurality of limit card blocks 34 cooperate with the limit card slot 37;

[0030] A plurality of elastic members 35 are slidably connected in the connection block 31 , and the plurality of elastic members 35 are used to limit the circular clamping block 36 .

[0031] The elastic member 35 includes a triangular block 351 and a spring 352. A plurality of cavities are provided in the connection block 31. The spring 352 is fixedly connected in the cavity. A triangular block 351 is fixedly connected to one side of the spring 352. A plurality of connecting grooves 361 are provided in the circular block 36. The plurality of connecting grooves 361 cooperate with the plurality of triangular blocks 351. When installed, the plurality of limit blocks 34 are connected to the limit grooves 37. When subjected to force, the limit blocks 34 will first be subjected to force to squeeze the limit grooves 37. To avoid the data line 5 being directly stressed when being pulled, causing deformation or breakage, when the circular clamping block 36 is inserted into the circular clamping slot 33, the circular clamping block 36 will squeeze the inclined surface of the triangular clamping block 351. The setting of the inclined surface facilitates the triangular clamping block 351 to shrink inward by squeezing the spring 352 in the cavity. Then, when the triangular clamping block 351 is located at the connecting slot 361, it automatically pops out into the connecting slot 361, clamps the circular clamping block 36, and limits it, which makes installation convenient and the connection stable.

[0032] A conductive protrusion 38 is fixed on one side of the connecting block 31, and a power-on terminal 32 is fixed on one end of the circular clamping block 36. The conductive protrusion 38 cooperates with the power-on terminal 32. When the data line 5 is subjected to force, the circular clamping block 36 is plugged into the triangular clamping block 351, which further limits the circular clamping block 36. When subjected to force, the power-on terminal 32 of the circular clamping block 36 and the conductive protrusion 38 will not be directly separated by force, thereby improving the stability of the data line connection.

[0033] A plurality of arc-shaped grooves 41 are formed on one side of the protective sleeve 4 outside the connecting block 31 .

[0034] A plurality of limit blocks 34 are arranged around the protective cover 4 and at intervals, and an opening 341 is provided between the limit blocks 34 at the same level, and the side section of the limit block 34 is triangular. When connected, it is convenient to push the limit block 34 into the limit slot 37 according to the position of the limit slot 37, and the limit slot 37 is consistent with the shape of the limit block 34, so that the limit slot 37 can perform preliminary limiting on the limit block 34. When the data line 5 is subjected to force, the limit block 34 squeezes the limit slot 37 to form resistance, which reacts to the pulling force it receives, thereby further improving the stability of the data line connection and the anti-pulling ability of the data line when connected.
