Description

Technical Field

[0001] The utility model belongs to the technical field of cable connection of energy storage cabinets and relates to a cable connector for energy storage equipment which can prevent misconnection. Background Art

[0002] Energy storage generally refers to the storage of electrical energy. Simply put, it means storing some energy first and using it when it is needed. It is mainly aimed at green and renewable energy such as wind energy, solar energy, and wind energy. The container energy storage system has the characteristics of simplified infrastructure construction costs, short construction period, high degree of modularization, easy transportation and installation, etc. It can be applied to thermal, wind, solar power stations or islands, communities, schools, scientific research institutions, factories, large load centers and other applications.

[0003] A search revealed a cable connector and a cable connection method thereof (Application Number: CN202410586960.4; Publication Number: CN118156911B). This connector includes a left cable connection structure and a right cable connection structure, connected by an arc-shaped support plate. Both structures include a housing mechanism, an end-face sealing mechanism disposed at one end of the housing, and slidingly engaged with the housing. A dual shielding mechanism is coaxially disposed at the other end of the housing, and slidingly engaged with the housing. The dual shielding mechanism includes an inner shielding cover, which tightly fits between the inner shielding cover of the left cable connection structure and the inner shielding cover of the right cable connection structure. Although the cable splice is completely enclosed within the spherical shielding cover formed by the two inner shielding covers, providing dual shielding of interference signals at the splice, when multiple cables need to be connected, due to the identical connector structures, it is difficult for operators to distinguish the corresponding cables, which can easily lead to docking errors.

[0004] Based on this, we designed a cable connector for energy storage equipment that prevents misconnection. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and propose a cable connector for energy storage equipment to prevent misconnection. The technical problem to be solved by the device is: how to achieve independent correspondence between the two connectors of the cable connector to prevent docking errors.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A cable connector for preventing misconnection for energy storage equipment includes a first connector and a second connector, both of which include an outer shell. A first docking terminal and a first connecting ring are provided at the end of the outer shell on the first connector, and the first connecting ring is sleeved on the outside of the first docking terminal. A second docking terminal and a second connecting ring are provided at the end of the outer shell on the second connector, and the second connecting ring is sleeved on the outside of the second docking terminal. A clamping assembly is provided between the first connecting ring and the second connecting ring. A first adjusting ring is rotatably provided on the outside of the first connecting ring, and a docking hole is provided on the first adjusting ring. A ring groove is provided on the outside of the second connecting ring, and a second adjusting ring is rotatably provided in the ring groove. A docking rod is fixed on the second adjusting ring.

[0008] The outer side of the second connecting ring is threadedly connected to a second screw, and the washer on the second screw abuts against the second adjusting ring to fix the second adjusting ring. The outer side of the first connecting ring is provided with a screw base, and the screw base is threadedly connected to a first screw, and the washer on the first screw abuts against the first adjusting ring to fix the first adjusting ring.

[0009] With the above structure, when in use, after the operator has adjusted the first adjusting ring and the second adjusting ring, they can be fixed respectively by the first and second screws, thereby preventing the first and second adjusting rings from shifting during subsequent maintenance, thereby ensuring the continued effectiveness of the corresponding relationship.

[0010] The clamping assembly includes hooks arranged on both sides of the second connecting ring, and the two hooks are symmetrically distributed. A positioning protrusion is provided on the outer side of the second connecting ring, a slot for clamping the hooks is provided on the first connecting ring, and a positioning groove aligned with the positioning protrusion is provided on the inner side of the first connecting ring.

[0011] With the above structure, when connecting, the second connecting ring is inserted into the inner side of the first connecting ring, and the positioning groove and the positioning protrusion need to be aligned, which can ensure that the first docking terminal and the second docking terminal can be correctly docked, and there will be no misalignment of the wires and short circuits. The hook and the bayonet can improve the connection stability between the first connecting ring and the second connecting ring, and prevent the cable connector from disconnecting during use.

[0012] An anti-slip cover is provided on the outside of the outer shell, and a first marking protrusion is fixed on one of the outer shells, and a second marking protrusion is fixed on the other outer shell.

[0013] With the above structure, during connection, the operator only needs to align the first marking protrusion and the second marking protrusion toward the same direction to dock the first connector with the second connector, which makes the operation more convenient.

[0014] A first clamping ring is fixed to the other end of the outer shell, and a spring collet is fixed to the inner side of the first clamping ring. A locking ring is connected to the outer side of the first clamping ring, and a clamping strip matching the first clamping ring is provided on the inner side of the locking ring. An inclined surface that presses against the spring collet is provided on the inner side of the locking ring.

[0015] With the above structure, when in use, the cable passes through the locking ring and the spring clamp, and the locking ring squeezes the spring clamp inward, so that the spring clamp clamps the cable to prevent the cable from falling off.

[0016] The end of the locking ring is provided with a second snap ring, the end of the second snap ring is provided with a flexible leather cover, and the inner side of the flexible leather cover is provided with a snap groove matching the second snap ring.

[0017] With the above structure, when in use, the flexible leather sleeve is arranged on the outside of the cable, which can prevent the cable from being frequently bent and cracked at the opening of the locking ring, thereby improving the protection effect of the cable.

[0018] Compared with the existing technology, the cable connector for energy storage equipment that prevents misconnection has the following advantages:

[0019] Through the first connecting ring, the second connecting ring, the first adjusting ring, the second adjusting ring and the docking rod, the docking hole needs to be aligned with the docking rod during connection, and the positions of the docking hole and the docking rod can be freely fixed to ensure that each pair of cable connectors will correspond individually, which can prevent the operator from docking incorrectly when multiple cable connectors need to be connected.

[0020] Through the snap-fit ​​assembly, when connected, the hook and the bayonet can improve the connection stability between the first connecting ring and the second connecting ring, prevent the cable connector from being disconnected during use, and improve the stability of the cable connector.

[0021] The cable passes through the locking ring and the spring clamp through the spring clamp and the locking ring. The locking ring squeezes the spring clamp inward so that the spring clamp clamps the cable to prevent the cable from falling off, thereby improving the connection stability between the cable and the first docking terminal or the second docking terminal.

[0022] The flexible leather cover protects the cable at the opening of the locking ring to prevent the cable from being squeezed and cracked by the edge of the locking ring when it is bent, thereby improving the protection effect of the cable. BRIEF DESCRIPTION OF THE DRAWINGS
