Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more particularly to an energy storage connector. Background Art

[0002] Energy storage connectors are connectors or joints used to connect energy storage systems (such as batteries, supercapacitors, etc.) with other electrical equipment (such as inverters, power grids, etc.). These connectors are typically designed for high current and high voltage applications to ensure the efficient operation and safety of energy systems. The design of energy storage connectors must take into account multiple factors such as electrical characteristics, plug and unplug cycles, and protection to meet the requirements of energy storage systems. In the development of the new energy field, energy storage connectors play an important role because they directly affect the performance and reliability of the system.

[0003] The Chinese patent publication number CN220628306U discloses an energy storage connector. When the mounting panel cover is connected to the mounting groove, the end face of the protrusion close to the mounting panel is flush with the end face of the base close to the mounting panel, so that the end face of the mounting panel close to the base can be simultaneously fitted with the end face of the protrusion close to the mounting panel and the end face of the base close to the mounting panel. The mounting panel, the base and the protrusion together form a space for accommodating a sealing gasket. The base and the mounting panel are connected by bolts. During the tightening of the bolts, the base and the protrusion are in contact with the mounting panel at the same time, thereby increasing the tightening force surface of the bolts, improving the structural strength of the base, reducing the cracking of the base during the tightening of the bolts, and increasing the fit tightness between the sealing gasket and the base, making it less likely to fall off. The bolts lock and squeeze the sealing gasket, which can also achieve a waterproof effect.

[0004] The male part of the connector is usually fixed to the equipment, but the female part is usually movable. It needs to be frequently plugged and unplugged during installation and maintenance, and a cable needs to be connected to the tail of the female socket.

[0041] Optionally, in some embodiments, see Figure 4 The plug assembly 8 includes a fixing plate 81, the outer end of the fixing plate 81 is fixedly connected to a sleeve 82, the sleeve 82 is adapted to the plug connector 51, the outer surround of the plug connector 51 abuts against the inner wall of the sleeve 82, and the bottom end of the fixing plate 81 is fixedly connected to a wiring nose 83, which passes through the female socket 1 and extends to the inside of the connecting tube 2.

[0042] The plug assembly 8 in this solution is located inside the cavity inside the female socket 1, and a sleeve 82 is fixed at the outer end of the fixing plate 81. The space inside the sleeve 82 matches the plug connector 51, and a wiring nose 83 is fixed at the bottom of the fixing plate 81. The fixing plate 81, the sleeve 82 and the wiring nose 83 are integrally formed, and the interior of the wiring nose 83 is also hollow. After the head of the cable is peeled, it is inserted into the wiring nose 83, and then the wiring nose 83 is flattened with pliers to fix the cable and connect it for conductivity. The wiring nose 83 extends through the cavity inside the female socket 1 to the outside. When the connecting tube 2 is threadedly connected to the bottom of the female socket 1, the wiring nose 83 will be located inside the connecting tube 2.

[0043] Optionally, in some embodiments, see Figure 4-Figure 6The bottom end of the driving cylinder 31 is rotatably connected to a rotating ring 32, and the outer end of the connecting cylinder 2 is provided with a thread. The rotating ring 32 is threadedly connected to the outer periphery of the connecting cylinder 2. The rotating ring 32 pushes the driving cylinder 31 up and down through the threaded connection with the connecting cylinder 2. The bottom end of the connecting cylinder 2 is fixedly connected to the limiting ring 10.

[0044] The limiting assembly 3 also includes a plurality of push rods 34 distributed equidistantly in a ring shape. The outer end of the connecting tube 2 is provided with a plurality of movable holes 9 adapted to the push rods 34. The push rods 34 pass through the movable holes 9. One end of the push rods 34 is fixedly connected to a splint 35. The splint 35 is arranged in an arc shape. The other end of the push rod 34 is against the inclined surface 33. The push rod 34 drives the splint 35 to move by squeezing the inclined surface 33.

[0045] The limiting component 3 in this scheme is installed at the bottom of the connecting tube 2, wherein the bottom outer periphery of the connecting tube 2 is provided with a thread, and the rotating ring 32 is threadedly connected to it. At the same time, a limiting ring 10 is fixed at the bottom end of the connecting tube 2. The limiting ring 10 is mainly used to limit the rotating ring 32 to prevent it from disengaging from the thread on the connecting tube 2. An annular groove is provided on the top of the rotating ring 32, which is rotatably connected to the driving tube 31 through the annular groove. The driving tube 31 is also sleeved on the outer end of the connecting tube 2.

A plurality of movable holes 9 distributed in an annular shape are opened at the outer end of the connecting tube 2, and the push rod 34 passes through the movable hole 9 and moves therein. A splint is fixed at one end of the push rod 34 located inside the connecting tube 2 When the rotating ring 32 is rotated, the rotating ring 32 drives the driving cylinder 31 to move upward at the outer end of the connecting cylinder 2. At this time, since the push rod 34 abuts against the inclined surface 33 and the push rod 34 is restricted in the movable hole 9, the push rod 34 is squeezed by the inclined surface 33, which will force the push rod 34 to drive the clamping plate 35 to move toward the inside of the connecting cylinder 2. At this time, the clamping plate 35 will abut against the surface of the cable located inside the connecting cylinder 2. By squeezing the cable at the same time by multiple clamping plates 35, it can be clamped. The secondary fixation of the cable by the limit assembly 3 can not only prevent it from falling off, but also prevent the connection between the cable and the wiring nose 83 from being pulled when plugging and unplugging, thereby preventing the cable from loosening.

[0046] Working principle: When using this device, first fix the male plug component 4 to the electrical equipment with bolts. Then, the cable can be passed through the limit component 3 and the connecting tube 2. The interior of the wiring nose 83 is also hollow. After stripping the head of the cable, insert it into the interior of the wiring nose 83. Then use pliers to flatten the wiring nose 83. Then, the cable needs to be fixed for the second time. Rotate the rotating ring 32 so that the rotating ring 32 drives the driving tube 31 to move upward. At this time, since the push rod 34 abuts against the inclined surface 33, the push rod 34 is squeezed by the inclined surface 33. , it will force the push rod 34 to drive the clamping plate 35 to move into the connecting tube 2. Multiple clamping plates 35 squeeze the cable at the same time to clamp it. Finally, the female socket 1 can be inserted into the male plug assembly 4, and the plug connector 51 is inserted into the sleeve 82, so that the plug rod assembly 5 and the plug assembly 8 can be connected to transmit power. There is a gap between the plug connector 51 and the male plug 43, which is just adapted to the interface outside the female socket 1, so that the plug connector 51 and the male plug 43 can be inserted into the sleeve 82 and the annular groove respectively, so that they can conduct electricity when connected.
