[0032] 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.

[0033] like Figures 1 to 9 As shown, an explosion-proof European-style cable plug includes a European-style cable plug body 1, the shell of the European-style cable plug body 1 is made of an explosion-proof aluminum alloy steel plate, and has good explosion-proof performance. A stress cone 3 is clamped on the lower side of the European-style cable plug body 1, and silicone grease is applied to the stress cone 3 to install the stress cone 3. Both ends of the European-style cable plug body 1 are fixedly connected with U-shaped plates 5, and the insides of the two U-shaped plates 5 are rotatably connected with movable plates 6. Two positioning columns 7 are installed on the lower side of the European-style cable plug body 1, and side plates 4 are installed on both ends of the stress cone 3;

[0034] One side of the two movable plates 6 is slidably connected with a telescopic recess 8. Through the installation and use of the side plate 4 and the telescopic recess 8, the two can together limit and fix the positioning column 7 to ensure the stability of the stress cone 3. The telescopic recess 8 is used to fix the positioning column 7. A first connecting spring 9 is connected between the two telescopic recesses 8 and the movable plate 6. The front side of the European cable plug body 1 is fixedly connected with a docking sleeve 2. Both sides of the stress cone 3 are fixedly connected with connecting plates 10. The two connecting plates 10 have through-grooves 22 formed inside.

[0035] Two U-shaped seats 12 are fixedly installed on the lower side of the European cable plug body 1, and the first limit baffle 13 and the second limit baffle 14 are rotatably connected inside the two U-shaped seats 12. A second connecting spring 11 is fixedly connected between the first limit baffle 13 and the second limit baffle 14. By installing and using the first limit baffle 13 and the second limit baffle 14, as long as the two limit baffles with elastic force are squeezed, the limit on the limit baffle can be released and kept away from the connecting plate 10, so as to remove the stress cone 3. It is easy to use, and the first limit baffle 13 and the second limit baffle 14 are located in the card slot 22.

[0036] Two rubber balls 15 are installed on the front side of the main body 1 of the European-style cable plug, and two support plates 16 are installed on the outer side of the docking sleeve 2. The rubber balls 15 are located inside the support plates 16.

[0037] Both ends of the docking sleeve 2 are fixedly connected with L-shaped positioning plates 18, and both ends of the European cable plug head body 1 are installed with mounting blocks 17. The L-shaped positioning plates 18 are located inside the mounting blocks 17, and the rear sides of the two L-shaped positioning plates 18 are connected with elastic clips 20. Through the setting of the elastic clips 20, the elastic clips 20 can be just clipped into the mounting blocks 17. At the same time, as long as the elastic clips 20 are squeezed, the limit on the L-shaped positioning plates 18 can be released to remove the L-shaped positioning plates 18. Two cross clips 19 are fixedly installed on the front side of the European cable plug head body 1, and the cross clips 19 are used to fix the L-shaped positioning plates 18.

[0038] The positioning column 7 is located inside the side plate 4, and the upper side of the telescopic recess 8 passes through the movable plate 6 and extends to the other side of the movable plate 6. The lower sides of the two telescopic recesses 8 are connected to the bottom plate 21. Through the setting of the bottom plate 21, as long as the bottom plate 21 is pulled downward, the telescopic recess 8 will be moved away from the positioning column 7, which makes it easy to release the limit on the positioning column 7 so as to flexibly load and unload the stress cone 3.

[0039] A copper wire 23 is installed inside the stress cone 3. The upper side of the copper wire 23 passes through the stress cone 3 and extends to the upper side of the stress cone 3. A copper rod 24 is clamped on the upper side of the copper wire 23. Through the setting of the copper rod 24, the copper rod 24 can be used to crimp the stripped copper wire 23, so as to connect the copper rod 24 and the copper wire 23 together, which is conducive to the subsequent assembly of the entire European cable plug. The upper side of the stress cone 3 is connected to a round rod 26 in an array. The lower side of the copper rod 24 is provided with an array of positioning circular grooves 25. The upper side of the round rod 26 is clamped with the lower side of the copper rod 24 through the positioning circular groove 25.

[0040] A circular ring 27 is fixedly connected to the upper side of the stress cone 3 , and a rubber block 29 is connected to the inner side of the circular ring 27 in an array. An array of grooves 28 are provided on the outer surface of the copper rod 24 , and the inner side of the rubber block 29 is clamped with the outer surface of the copper rod 24 through the grooves 28 .

[0041] A through embedding hole 111 is provided inside the support plate 16 . The embedding hole 111 is adapted to fit the rubber ball 15 . The front side of the rubber ball 15 is engaged with the inside of the support plate 16 through the embedding hole 111 .

[0042] The working principle of an explosion-proof European-style cable plug provided by the utility model is as follows:

[0043] By squeezing the first limit baffle 13 and the second limit baffle 14 installed with the second connection spring 11, the two limit baffles can be retracted, so that as the stress cone 3 is installed, the two limit baffles can be snapped into the card slot 22 of the connecting plate 10, so as to preliminarily reinforce the installation of the stress cone 3, and then the side plate 4 at the stress cone 3 will be inserted into the positioning column 7, and then the movable plate 6 is rotated downward, so that the telescopic recess 8 installed with the first connection spring 9 at the movable plate 6 can be adaptively snapped into the bottom of the positioning column 7, so that the European-style cable plug and the stress cone 3 can be firmly fixed, and it is not easy to loosen and have poor contact, thereby ensuring the stability of the European-style cable plug during assembly;

[0044] By installing the docking sleeve 2 to the front of the European-style cable plug head body 1, the two rubber balls 15 will be embedded in the support plate 16 at the docking sleeve 2, which can be used to initially reinforce the installation of the docking sleeve 2, and then the two L-shaped positioning plates 18 at the docking sleeve 2 will be snapped into the two mounting blocks 17, and then the two elastic buckles 20 will be snapped into the rear of the mounting blocks 17 to further connect the docking sleeve 2 and the European-style cable plug head, which is convenient to use. At the same time, the two L-shaped positioning plates 18 can also be fixed at the position of the cross clamping plate 19 to ensure the stability of the installation of the docking sleeve 2 and prevent the docking sleeve 2 from falling off;

[0045] By clamping the copper rod 24 into the copper wire 23, the round rod 26 at the stress cone 3 will be inserted into the positioning circular groove 25 below the copper rod 24, so as to preliminarily clamp and position the copper rod 24 inside the European cable plug head, so that the copper rod 24 can be used in a stable state. Then, as the copper rod 24 is installed, the rubber block 29 at the ring 27 will automatically embed into the groove 28 around the copper rod 24, which is conducive to tightly connecting the copper rod 24 and the copper wire 23, so that the copper rod 24 can be used safely and reliably.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
