[0002] High-voltage energy storage connector is a professional electrical connection device designed for high-voltage energy storage system. It is mainly used to connect energy storage battery system, power conversion equipment, charging facilities and other high-voltage electrical components for power transmission.

[0003] Existing high-voltage energy storage connectors usually fix the cable by screwing a nut on the threaded part and then using the nut to squeeze the wire clamp and the waterproof collar. Although the purpose of connection and fixation can be achieved, there are still some problems in daily use. The stability and anti-loosening performance of the nut will be reduced after long-term use, which will cause the internal threaded tube to loosen and cause the line connection to have a virtual connection and disconnection problem. Secondly, when the connecting line is subjected to axial pressure changes, the waterproof collar will separate from the connecting line, which cannot guarantee the effective sealing effect of the high-voltage energy storage connector throughout its entire use cycle.

[0007] The anti-loosening component also includes circular grooves respectively arranged on the inner side surfaces of the limit sliders, and springs are arranged between the inner wall surfaces of the circular grooves and the corresponding wall surfaces of the rectangular grooves in which they are located; the anti-loosening component also includes guide grooves longitudinally symmetrically arranged on the upper ends of the outer arc surfaces of the internally threaded tubes, the guide grooves are respectively connected with the limit grooves adjacent to the same side, and sliding buttons are slidably connected in the guide grooves, and the inner ends of the sliding buttons are respectively cooperated with the limit sliders adjacent to the same side.

[0008] The floating sealing component includes annular grooves respectively arranged on the upper and lower ends of the inner arc surface of the internal threaded tube, annular sealing airbags are arranged in the annular grooves, the outer arc surface of the connecting line is matched with the outer arc surface of the annular sealing airbag at the lower end, and the outer arc surface of the external threaded tube is matched with the outer arc surface of the annular sealing airbag at the upper end; the floating sealing component also includes a shunt pipe arranged on the lower side of the front end of the internal threaded tube, the two air outlets of the shunt pipe respectively penetrate the inner arc surface of the adjacent annular groove on the same side and extend to the inside thereof, the two air outlets of the shunt pipe are respectively connected with the air inlet holes arranged on the outer arc surface of the adjacent annular sealing airbag on the same side, the air inlet of the shunt pipe penetrates the outer arc surface of the internal threaded tube and a valve core valve is arranged at the end.

[0009] The lower ends of the outer ends of the limiting sliding blocks are all arranged to be tilted downward from the outside to the inside.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] 1. During the screwing process of the internal threaded tube and the external threaded barrel, the internal threaded tube will contact and slide relatively with the limit slider, and the limit slider will overcome the elastic force of the spring and retract into the rectangular groove for avoidance after being subjected to force. After the internal threaded tube and the external threaded barrel are completely screwed together, the limit slider will be just opposite to the limit groove. At this time, the limit slider will immediately be inserted into the limit groove under the action of the spring rebound force, thereby limiting the internal threaded tube, ensuring the stability and anti-loosening of the internal threaded tube during use, and solving the problem of virtual connection and disconnection at the line connection caused by loose internal threaded tube.

[0012] 2. After the connecting line is installed, the relevant staff will pump gas of appropriate pressure into the annular sealing airbag through the valve core valve and the shunt pipe, so that the annular sealing airbag will expand and seal with the corresponding connecting line and the external threaded tube. Due to the compressible characteristics of the gas, when the connecting line is subjected to axial pressure changes, the annular sealing airbag will elastically expand and contract to adapt to the changes, thereby ensuring that the high-voltage energy storage connector always maintains an effective sealing effect throughout its entire service life.

[0013] 3. When you need to disassemble and replace the connecting wire, just press the sliding buttons at the same time. The sliding buttons push the limit slider to overcome the elastic force of the spring and retract into the rectangular groove, thereby separating the limit slider from the limit groove. At this time, turn the internal threaded tube counterclockwise to disassemble it, which is convenient for relevant staff to disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-4 As shown, the floating seal assembly includes annular grooves 400 respectively arranged on the upper and lower ends of the inner arc surface of the internal threaded tube 201, and annular sealing airbags 401 are arranged in the annular grooves 400. The outer arc surface of the connecting line 203 is matched with the outer arc surface of the annular sealing airbag 401 at the lower end, and the outer arc surface of the external threaded tube 200 is matched with the outer arc surface of the annular sealing airbag 401 at the upper end; the floating seal assembly also includes a shunt tube 402 arranged on the lower side of the front end of the internal threaded tube 201, and the two air outlets of the shunt tube 402 respectively penetrate the inner arc surface of the adjacent annular groove 400 on the same side and extend to the inside thereof, and the two air outlets of the shunt tube 402 are respectively connected with the air inlet holes arranged on the outer arc surface of the adjacent annular sealing airbag 401 on the same side, and the air inlet of the shunt tube 402 penetrates the outer arc surface of the internal threaded tube 201 and a valve core valve 403 is provided at the end.

[0023] The working principle of a high-voltage energy storage connector provided by the utility model is as follows: when it is necessary to install the connecting wire 203, the relevant staff connects the connecting wire 203 with the plug-in connecting tube 202, and then movably sets the waterproof cover 204 on the connection between the connecting wire 203 and the plug-in connecting tube 202, and then sets the wire clamping cap 205 on the waterproof cover 204. After that, the relevant staff threadably connects the internal threaded tube 201 with the external threaded tube 200. As the internal threaded tube 201 and the external threaded tube 200 are gradually screwed together, the internal threaded tube 201 will squeeze the wire clamping cap 205, so that the clamping cap The wire cap 205 squeezes the waterproof sleeve 204 to reinforce the connection line 203 and the plug-in connection tube 202, ensuring the connection reliability and safety when the connector 100 is running in a high voltage and high current environment. At the same time, the internal threaded tube 201 will contact and slide relatively with the limit slider 301, and the limit slider 301 will overcome the elastic force of the spring 304 and retract into the rectangular groove 300 for avoidance after being subjected to force. After the internal threaded tube 201 and the external threaded tube 200 are completely screwed together, the limit slider 301 will be exactly opposite to the limit groove 302, and at this time the limit slider 301 will The inner threaded tube 201 is immediately inserted into the limiting groove 302 under the action of the rebound force of the spring 304, thereby limiting the position of the inner threaded tube 201, ensuring the stability and anti-loosening of the inner threaded tube 201 when in use, and solving the problem of virtual connection and disconnection at the line connection caused by the loosening of the inner threaded tube 201. When it is necessary to disassemble and replace the connecting line 203, it is only necessary to press the sliding button 306 at the same time. The sliding button 306 pushes the limiting slider 301 to overcome the elastic force of the spring 304 and retract it into the rectangular groove 300, thereby separating the limiting slider 301 from the limiting groove 302. At this time, the inner threaded tube 201 can be rotated counterclockwise to enter. After the connection line 203 is installed, the relevant staff will pump gas of suitable pressure into the annular sealing airbag 401 through the valve core valve 403 and the shunt pipe 402, so that the annular sealing airbag 401 will expand and contact and seal with the corresponding connection line 203 and the external threaded tube 200. Due to the compressible characteristics of the gas, when the connection line 203 is subjected to axial pressure changes, the annular sealing airbag 401 will elastically expand and contract to adapt to the changes, thereby ensuring that the high-voltage energy storage connector always maintains an effective sealing effect throughout its entire service life.

[0024] like Figure 2-3 As shown, the lower ends of the outer ends of the limiting sliders 301 are tilted downward from the outside to the inside, so that the internal threaded tube 201 is smoother during the tightening process.
