[0044] The technical scheme of the utility model will be further illustrated below by combining the drawings and through specific embodiments.

[0045] Embodiment 1

[0046] Please refer to Figures 1-2 The utility model embodiment provides a kind of cable stable clamping structure, cable plug-in unit 1, the cable plug-in unit 1 is used for cable 4 insertion;

[0047] a tail fixing unit 2, which is sleeved and fixed on the cable plug-in unit 1;

[0048] a cable clamping unit 3, which comprises a plurality of clamping pieces 32 arranged on the end of the tail fixing unit 2 away from the cable plug-in unit 1 and surrounding to form a squeezing hole for clamping the cable 4.

[0049] Specifically, the tail fixing unit 2 is a ring structure, which is installed on the cable plug-in unit 1 for inserting the tail of the cable. After the cable 4 is inserted into the cable plug-in unit 1, the tail fixing unit 2 is sleeved on the cable plug-in unit 1. By sleeving with the cable plug-in unit 1, an inward pressure is generated on the cable plug-in unit 1, so that the inner wall of the cable plug-in unit 1 is tightly attached to the inserted cable 4, thereby providing a stable anchor point for the cable, avoiding the cable from loosening or directly separating from the cable plug-in unit 1 due to external force.

[0050] The cable clamping unit 3 directly contacts with the cable 4 to clamp and fix the cable, so that the cable cannot be loosened or separated from the cable plug-in unit 1 due to pulling or other external factors. The plurality of clamping pieces 32 are fixed on the end of the tail fixing unit 2 away from the cable plug-in unit 1 to surround and form a squeezing hole for clamping the cable, and the squeezing hole surrounds the outside of the cable to clamp and fix the cable.

[0051] The tail fixing unit 2 is sleeved on the cable plug-in unit 1, and the cable plug-in unit 1 is squeezed to tightly grip the inserted cable, thereby ensuring the stable clamping of the cable on the charging gun. Meanwhile, the plurality of clamping pieces 32 are fixed on the end of the tail fixing unit 2 away from the cable plug-in unit 1 to clamp and fix the cable inserted into the cable plug-in unit 1, thereby realizing the second fixation of the cable and avoiding the cable from loosening or separating from the cable plug-in unit 1 due to external force.

[0052] The tail fixing unit 2 is sleeved on the outside of the cable plug-in unit 1, and the cable is fixed in the cable plug-in unit 1 by tightly squeezing the cable plug-in unit 1. The force of the tail fixing unit 2 on the cable plug-in unit 1 is uniformly distributed on the contact position of the cable plug-in unit 1, and the force transmitted to the cable is also uniformly applied to each position of the cable and the cable connection unit, so that the cable is fixed in the cable connection unit by the uniform tightening force applied to the outside of the cable. When subjected to external force, the force between the cable and the plug-in end 121 is uniformly distributed on the contact position, thereby avoiding the problems of cable damage and poor contact due to uneven force.

[0053] In an embodiment, asFigure 2 As shown, the clamping piece 32 includes a first clamping piece 321 and a second clamping piece 322, which are symmetrically arranged.

[0054] The first clamping piece 321 and the second clamping piece 322 are semicircular structures, and are fixedly connected with the tail fixing unit 2, so that the clamping piece 32 and the cable plug-in unit 1 are an integral whole, realizing the second fixation between the cable and the cable plug-in unit 1. At the same time, the semicircular structure can uniformly distribute the pressure received by the cable, avoiding damage to the cable due to excessive force on a single point. At the same time, the symmetrically arranged first clamping piece 321 and the second clamping piece 322 can better adapt to cables of different diameters, ensuring the stability of clamping.

[0055] In an embodiment, as shown in the drawings, Figure 3 The cable plug-in unit 1 includes a main body shell 12, one end of which is provided with a plug-in end 121 for inserting a cable, and the periphery of the plug-in end 121 is provided with a first fastening thread 122.

[0057] Specifically, the inner diameter of the tail fixing unit 2 is greater than the outer diameter of the plug-in end 121, so that the tail fixing unit 2 can be directly sleeved on the plug-in end 121. The plug-in end 121 is a hollow structure, and is used for connecting the cable inserted from the plug-in end 121 to the electrical parts arranged inside the main body shell 12 for electrical transmission.

[0058] By arranging the first fastening thread 122 on the periphery of the plug-in end 121 of the main body shell 12 and the second fastening thread 22 inside the tail fixing unit 2, the second fastening thread 22 of the tail fixing unit 2 is aligned with the first fastening thread 122 of the main body shell 12, and the tail fixing unit 2 is rotated along the first direction (usually clockwise), and the tail fixing unit 2 is rotated until the tail bone fixing unit is rotated to a preset position (or until it is completely tightened), realizing reliable connection between the tail fixing unit 2 and the main body shell 12. After the cable is inserted into the charging gun, the cable is prevented from falling off due to external force by the fixing effect of the tail fixing unit 2, and at the same time, the connection between the cable and the main body of the charging gun is stable and reliable.

[0059] Through the design, the connection strength between the cable and the charging gun is ensured, and a large pulling-off force 1500N can be borne, far exceeding the standard requirement (500N required by 250A national standard).

[0066] Two first through holes 3211 are arranged at both ends of the first clamping member 321, and two second through holes 3222 are arranged at both ends of the second clamping member 322. The first through hole 3211 and the second through hole 3222 pass through the circular surface of the clamping member and pass out from both ends of the clamping member.

[0067] When the first clamping member 321 and the second clamping member 322 are mounted on the tail fixed part, one end of a first fixing member 31 is inserted from the first through hole 3211, and after the first fixing member 31 passes through the first through hole 3211, it is fixedly connected with the second through hole 3222 of the second clamping member 322 after passing through the first insertion hole 2111 of the first fixed part 212. Similarly, after a first fixing member 31 passes through the first through hole 3211 of the first clamping member 321 and then passes through the second insertion hole 2112 of the second fixed part 213, it is fixedly connected with the second through hole 3222, thereby achieving the fixation of the cable clamping unit 3 on the outer side end 27 of the tail fixed unit 2.

[0068] The first fixing member 31 is used to connect the tail fixed unit 2 and the clamping member in this embodiment, and the distance between the first clamping member 321 and the second clamping member 322 can be adjusted by the first fixing member 31, thereby achieving the clamping and fixation of cables of different sizes.

[0069] By arranging a set of symmetric fixed parts and the first through hole 3211 and the second through hole 3222 on the first clamping member 321 and the second clamping member 322, and by the first fixing member 31, the fixation between the first clamping member 321 and the second clamping member 322 and the fixation between the clamping member and the fixed part are achieved, thereby ensuring that the cable cannot be easily loosened in any direction.
