Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector structure with a self-locking structure for energy storage equipment. Background Art

[0002] Energy storage connector is a connector used in energy storage systems to connect energy storage devices, battery packs, inverters and other related equipment.

[0003] The connector structure used in existing energy storage devices does not have a self-locking structure, and the interfaces and connectors are prone to loosening after being connected, causing loose connections, which can easily lead to poor contact in power transmission; and after the plug and socket are connected, they do not have a waterproof function, and when there is water in the installation environment, water penetration will occur, causing leakage.

[0004] In order to solve the above problems, we propose a connector structure for energy storage devices with a self-locking structure. Utility Model Content

[0005] The utility model aims to provide a connector structure for energy storage equipment with a self-locking structure, which has the advantages of being able to self-lock and prevent loosening and having waterproof functions.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a connector structure for energy storage equipment with a self-locking structure, including a joint and an interface, a fixed disk is fixedly sleeved on the surface of the interface, two through grooves are provided inside the fixed disk, one side of the joint is fixedly connected to two connecting plates, a side of the connecting plate away from the interface is fixedly connected to a telescopic rod, a spring is sleeved on the surface of the telescopic rod, and a clamping block is fixedly connected to the other end of the telescopic rod; a sealing groove is provided on one side of the interface, and a sealing ring that is sealed and clamped with the sealing groove is fixedly connected to one side of the joint.

[0007] By adopting the above technical solution, by setting a card block, a telescopic rod, a spring, a connecting plate, a fixed plate and a through groove, the joint and the interface can be self-locked after being docked, and the joint and the interface can be locked to prevent the joint and the interface from separating; by setting a sealing groove and a sealing ring, the sealing groove and the sealing ring will be engaged to form a seal after the joint and the interface are docked.

[0008] The utility model is further configured as follows: one end of the spring is fixedly connected to the connecting plate through a spring fixing piece, and the other end of the spring is fixedly connected to the clamping block through a spring fixing piece.

[0009] By adopting the above technical solution, through the setting of the spring, the spring can be compressed and then rebound. When the card block passes through the through slot, the spring will be compressed by the fixed disk. After the card block passes through the through slot, the spring can push the card block to rebound and reset to clamp the fixed disk.

[0010] The utility model is further configured as follows: a receiving groove is provided on one side of the clamping block close to the connecting plate, and the telescopic rod and the spring are both located inside the receiving groove.

[0011] The above technical solution is adopted to store the compressed spring through the provision of the storage groove.

[0012] The utility model is further configured as follows: the length and width of the clamping block are both smaller than the through slot.

[0013] By adopting the above technical solution, the length and width of the card block are smaller than the through slot, so as to ensure that the card block can pass through the through slot, and after the spring pops out, the card block can be stuck on one side of the fixed disk.

[0014] The utility model is further configured as follows: one side of the connecting plate penetrates to the outer side of the fixing plate.

[0015] By adopting the above technical solution, the telescopic rod, the spring and the clamping block are supported by the setting of the connecting plate.

[0016] The utility model is further configured as follows: a side of the clamping block close to the fixing disk is in contact with the fixing disk.

[0017] By adopting the above technical solution, the side of the card block close to the fixed disk is arranged to contact the fixed disk. The contact between the card block and the fixed disk can form a pulling force between the connector and the interface, thereby locking the connector and the fixed disk so that the connector and the interface cannot be separated.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The utility model connects the telescopic rod and the spring by setting a connecting plate, and connects the card block through the telescopic rod. When the joint and the interface are connected, the card block will pass through the through slot and be squeezed by the fixed disk, so that the spring compresses the output end of the telescopic rod and retracts. After the card block passes through the through slot, the spring and the telescopic rod rebound and push the card block and the fixed disk to engage, thereby achieving self-locking. By setting a connector structure with a self-locking structure, loose connection and poor contact can be avoided;

[0020] 2. The utility model provides a sealing ring and a sealing groove on the joint and the interface respectively. After the joint and the interface are connected, the sealing ring and the sealing groove are snapped together to form a seal, thereby preventing water penetration and avoiding short circuits caused by water.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A connector structure for energy storage equipment with a self-locking structure includes a joint 1 and an interface 2. A fixed disk 3 is fixedly sleeved on the surface of the interface 2. Two through grooves 4 are provided inside the fixed disk 3. Two connecting plates 5 are fixedly connected to one side of the joint 1. A telescopic rod 6 is fixedly connected to the side of the connecting plate 5 away from the interface 2. A spring 7 is sleeved on the surface of the telescopic rod 6. A clamping block 8 is fixedly connected to the other end of the telescopic rod 6. A sealing groove 9 is provided on one side of the interface 2. A sealing ring 10 sealed and clamped with the sealing groove 9 is fixedly connected to one side of the joint 1. The telescopic rod 6 and the spring 7 are connected by setting the connecting plate 5, and the clamping block 8 is connected through the telescopic rod 6. When the connector 1 and the interface 2 are docked, the block 8 will pass through the through slot 4 and be squeezed by the fixed disk 3, causing the spring 7 to compress the output end of the telescopic rod 6 and retract. After the block 8 passes through the through slot 4, the spring 7 and the telescopic rod 6 rebound and push the block 8 and the fixed disk 3 to engage, thereby achieving self-locking. By providing a connector structure with a self-locking structure, loose connection and poor contact can be avoided. By respectively providing a sealing ring 10 and a sealing groove 9 on the connector 1 and the interface 2, after the connector 1 and the interface 2 are docked, the sealing ring 10 and the sealing groove 9 can be engaged to form a seal, thereby preventing water penetration problems from occurring and avoiding short circuits caused by water.

[0029] Furthermore, one end of the spring 7 is fixedly connected to the connecting plate 5 via a spring fixing piece, and the other end of the spring 7 is fixedly connected to the clamping block 8 via a spring fixing piece. Through the setting of the spring 7, the spring 7 can be compressed and then rebound. When the clamping block 8 passes through the through slot 4, the spring 7 is compressed by the squeezing of the fixed disk 3, and after the clamping block 8 passes through the through slot 4, the spring 7 can push the clamping block 8 to rebound and reset to clamp the fixed disk 3.

[0030] Furthermore, a receiving groove 11 is provided on one side of the clamping block 8 close to the connecting plate 5 , and the telescopic rod 6 and the spring 7 are both located inside the receiving groove 11 . The receiving groove 11 is provided to receive the compressed spring 7 .

[0031] Furthermore, the length and width of the block 8 are smaller than the through slot 4. By making the length and width of the block 8 smaller than the through slot 4, it can be ensured that the block 8 can pass through the through slot 4, and after the spring 7 pops out, the block 8 can be stuck on one side of the fixed disk 3.

[0032] Furthermore, one side of the connecting plate 5 penetrates to the outer side of the fixing plate 3 , and the setting of the connecting plate 5 supports the telescopic rod 6 , the spring 7 and the clamping block 8 .

[0033] Furthermore, the side of the card block 8 close to the fixed disk 3 is in contact with the fixed disk 3. By setting the side of the card block 8 close to the fixed disk 3 in contact with the fixed disk 3, the contact between the card block 8 and the fixed disk 3 can form a pulling force between the connector 1 and the interface 2, thereby locking the connector 1 and the fixed disk 3 so that the connector 1 and the interface 2 cannot be separated.

[0034] Brief description of the use process: when in use, dock the connector 1 and the interface 2. During the docking process, the block 8 will enter the interior of the through slot 4. As the connector 1 is pushed forward, the block 8 will be squeezed by the fixed disk 3. When the block 8 is squeezed, it will squeeze the telescopic rod 6 and the spring 7 respectively, so that the block 8 moves toward the connecting plate 5. After the block 8 passes through the through slot 4, the block 8 is no longer squeezed by the fixed disk 3. The spring 7 and the telescopic rod 6 will push the block 8 to rebound and reset. When the block 8 is reset, its length will be greater than the fixed disk 3. At this time, the block 8 will be stuck to the fixed disk 3, thereby forming a self-locking.

[0035] If disassembly is required, the two clamping blocks 8 can be pressed to make the length of the clamping blocks 8 smaller than the through slot 4 to separate the connector 1 and the interface 2;

[0036] After the connector 1 and the interface 2 are docked, the sealing groove 9 and the sealing ring 10 will also engage with each other. After the sealing groove 9 and the sealing ring 10 engage with each other, a seal will be formed, thereby preventing water from penetrating into the contact point between the connector 1 and the interface 2 and avoiding short circuits and the like.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
