Description

Technical Field

[0001] This utility model relates to the field of power cable connection, and in particular to the power cable connection structure of waterproof energy storage equipment. Background Technology

[0002] Waterproof energy storage devices refer to energy storage systems designed with additional waterproof protection measures. These devices are typically used outdoors or in environments where they may come into contact with moisture. They prevent moisture from penetrating the inside of the device, ensuring the safety of electrical connections and the normal operation of the device. The cables in the device are responsible for transmitting electrical energy and have a direct impact on the safety and reliability of the energy storage system. Through the connection mechanism in the cable, the cables are connected together and protected to ensure the safe and reliable operation of the energy storage system.

[0003] According to the patent application CN221202123U, "This utility model relates to the field of power equipment technology and discloses a connection structure for power cables, including an external protective mechanism. One side of the internal structure of the external protective mechanism is provided with a main line fixing mechanism, and the other side of the internal structure of the external protective mechanism is provided with two rotating mechanisms. Each of the two rotating mechanisms has a branch line fixing mechanism at its top. The external protective mechanism includes a protective panel, a protective side plate, a main line anti-slip opening, and a movable groove. This connection structure for power cables allows the mounting plate and the branch line fixing mechanism to rotate via a rotating shaft, so that the branch line fixing mechanism can fix a branch line in a direction different from the main line. By inserting both sides of the branch line movable block into the branch line guide groove, the branch line movable block can move within it. By controlling the branch line fixing screw, the branch line movable block moves towards the branch line fixing block, thus fixing the branch line between the branch line fixing block and the branch line movable block."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model uses a single smooth fixing block to fix the cable. During fixing, the cable only receives vertical downward pressure, which is not a firm fix. This can cause the cable to loosen and fall off, resulting in damage and affecting the cable's service life. Therefore, it is necessary to improve the power cable connection structure of waterproof energy storage equipment to solve the above problems. Utility Model Content

[0006] To overcome the problem that cables may become loose and fall off due to insecure fixing during installation, thus damaging them and affecting their service life.

[0007] The technical solution of this utility model is as follows: a waterproof energy storage device power cable connection structure, including a main shell and a base plate, and further including a first branch clamping plate, a branch anti-slip pad, a guide rod, a second branch clamping plate and a main clamping mechanism. The base plate is fixedly connected to the back of the main shell, the main clamping mechanism is provided inside the main shell, the guide rod is provided inside the main shell, the first clamping plate is slidably connected to the outside of the guide rod, the second clamping plate is fixedly connected to the outside of the guide rod, and the branch anti-slip pads are fixedly connected inside the first clamping plate and the second clamping plate respectively.

[0008] Preferably, the main housing has a first threaded rod internally threaded, a slider internally fixedly connected to the first threaded rod, a slide rod internally fixedly connected to the slider, a rotating rod fixedly connected to the front of the main base plate, a rotating shaft externally rotatably connected to the rotating rod, a branch base externally fixedly connected to the rotating shaft, the slide rod sliding inside the branch base, a branch sleeve internally fixedly connected to the branch base, a first clamping plate slidably connected to the branch sleeve, a guide rod fixedly connected to the branch sleeve, a second threaded rod internally threaded to the branch sleeve, a connecting block internally fixedly connected to the first clamping plate, and a spring fixedly connected between the first clamping plate and the second clamping plate.

[0009] Preferably, two branch sleeves are provided, and the two branch sleeves are symmetrically arranged inside the main housing.

[0010] Preferably, there are two slide rods, which are symmetrically fixedly connected inside the slider. The support base has a groove at the relative position of the slide rods, and the slide rods slide in the groove.

[0011] Preferably, there are two first clamping plates and two second clamping plates, which are symmetrically arranged inside the branch sleeve.

[0012] Preferably, the main clamping mechanism includes a main circuit outer plate, which is fixedly connected inside the main housing. A bidirectional threaded rod is threadedly connected inside the main circuit outer plate. A sliding rail is fixedly connected inside the main circuit outer plate. A knob is fixedly connected to the front of the bidirectional threaded rod. A fixing buckle is fixedly connected inside the main housing. The bidirectional threaded rod is rotatably connected inside the fixing buckle. A main line clamping plate is slidably connected inside the sliding rail. The main line clamping plate is threadedly connected to the outside of the bidirectional threaded rod. A main line anti-slip pad is provided inside the main line clamping plate.

[0013] Preferably, there are two main line clamping plates, which are symmetrically slidably connected inside the sliding rail. There are eight main line anti-slip pads, which are symmetrically arranged inside the two main line clamping plates.

[0014] The beneficial effects of this utility model are as follows: Compared with using a single smooth fixing block, by adding branch line anti-slip pads and main line anti-slip pads, the friction force on the cable is increased when clamping the branch line cable and the main line cable, making the cable more firmly fixed. This avoids the problem of the cable loosening and falling off due to insecure fixing, which would cause damage and affect the service life of the cable. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a waterproof energy storage device power cable connection structure, including a main housing 1 and a base plate 4, and further including a branch line first clamping plate 210, a branch line anti-slip pad 211, a guide rod 212, a branch line second clamping plate 214, and a main clamping mechanism. The base plate 4 is fixedly connected to the back of the main housing 1. The main clamping mechanism is provided inside the main housing 1. The guide rod 212 is provided inside the main housing 1. The first clamping plate 210 is slidably connected to the outside of the guide rod 212. The second clamping plate 214 is fixedly connected to the outside of the guide rod 212. The branch line anti-slip pads 211 are fixedly connected to the inside of the first clamping plate 210 and the second clamping plate 214, respectively. The main cable enters through the top of the main housing 1 and rotates... The knob 34 causes the main cable clamping plate 36 to slide towards it, pressing the main cable. The main cable anti-slip pad 37 provides friction to the main cable, making the main cable more secure and preventing it from falling off or loosening. The branch cable enters the interior through the bottom of the main housing 1. The second threaded rod 28 is rotated to drive the branch cable first clamping plate 210 to slide towards the branch cable second clamping plate 214, pressing the branch cable. The branch cable anti-slip pad 211 provides friction to the branch cable, making the branch cable more secure and preventing it from falling off or loosening. Depending on the angle of the branch cable connection, the first threaded rod 21 is rotated to drive the branch cable base 26 to rotate, causing the branch cable sleeve 27 to rotate, thereby facilitating the connection of the main cable and different branch cables.

[0023] Please see Figure 1-Figure 4In this embodiment, the main housing 1 is internally threaded with a first threaded rod 21, a slider 22 is fixedly connected inside the first threaded rod 21, and a slide rod 23 is fixedly connected inside the slider 22. A rotating rod 24 is fixedly connected to the front of the main base plate 4, a rotating shaft 25 is rotatably connected to the outside of the rotating rod 24, and a branch base 26 is fixedly connected to the outside of the rotating shaft 25. The slide rod 23 slides inside the branch base 26, and a branch sleeve 27 is fixedly connected inside the branch base 26. A first clamping plate 210 is slidably connected inside the branch sleeve 27, a guide rod 212 is fixedly connected inside the branch sleeve 27, a second threaded rod 28 is internally threaded with the branch sleeve 27, a connecting block 29 is fixedly connected inside the first clamping plate 210, and a spring 213 is fixedly connected between the first clamping plate 210 and the second clamping plate 214. The slide rod 23 cooperates with the branch base 26 to make the branch base 26... The main housing 1 has two branch sleeves 27, which can be rotated to adjust the angle of connection to the branch cable. Two branch sleeves 27 are symmetrically arranged inside the main housing 1. The main cable can connect two branch cables through the two branch sleeves 27. Two slide rods 23 are symmetrically fixed inside the slider 22. The branch base 26 has a groove at the opposite position of the slide rod 23. The slide rod 23 slides in the groove. The groove inside the branch base 26 guides the slide rod 23, allowing it to rotate. Two first clamping plates 210 and two second clamping plates 214 are provided. The two first clamping plates 210 and two second clamping plates 214 are symmetrically arranged inside the branch sleeves 27. The two branch first clamping plates 210 and two branch second clamping plates 214 better fix the branch cable and prevent it from loosening and falling off.

[0024] Please see Figures 1-2 , Figure 5In this embodiment, the main clamping mechanism includes a main circuit outer plate 31, which is fixedly connected to the inside of the main housing 1. A bidirectional threaded rod 32 is threadedly connected to the inside of the main circuit outer plate 31. A sliding rail 33 is fixedly connected to the inside of the main circuit outer plate 31. A knob 34 is fixedly connected to the front of the bidirectional threaded rod 32. A fixing buckle 35 is fixedly connected to the inside of the main housing 1. The bidirectional threaded rod 32 is rotatably connected to the inside of the fixing buckle 35. A main wire clamping plate 36 is slidably connected to the inside of the sliding rail 33. The main wire clamping plate 36 is threadedly connected to the outside of the bidirectional threaded rod 32. The main line clamping plate 36 is equipped with a main line anti-slip pad 37 inside. By rotating the bidirectional threaded rod 32, the main line clamping plate 36 slides synchronously to clamp the main line cable. There are two main line clamping plates 36, which are symmetrically slidably connected inside the sliding rail 33. There are eight main line anti-slip pads 37, which are symmetrically arranged inside the two main line clamping plates 36. By setting eight main line anti-slip pads 37, the friction force on the main line cable is better provided, preventing it from loosening and falling off due to insecure fixing, thus preventing damage to the main line cable.

[0025] During operation, the main housing 1 is separated from the base plate 4. The main cable enters the main housing 1 through the top. By rotating the knob 34, the bidirectional threaded rod 32 is rotated, causing the main cable clamping plate 36 outside the bidirectional threaded rod 32 to slide towards it, clamping the main cable. The anti-slip pad 37 inside the main cable clamping plate 36 further increases friction, preventing loosening and detachment after clamping, thus avoiding damage to the main cable caused by loosening or detachment. The branch cable enters the main housing 1 through the bottom. Depending on the required angle, the first threaded rod 21 is rotated, and the slider 22 cooperates with the slide rod 23 to drive the branch base 26 at the bottom of the branch sleeve 27. The required angle is adjusted by rotating the second threaded rod 28, which drives the first clamping plate 210 to move closer to the second clamping plate 214 to clamp the branch cable. The branch anti-slip pads 211 provided on the first clamping plate 210 and the second clamping plate 214 provide friction to the branch cable to prevent it from loosening and falling off after clamping, thereby avoiding damage to the branch cable caused by loosening and falling off.

[0026] By adding branch line anti-slip pads 211 and main line anti-slip pads 37 through the above steps, the friction between the branch line cable and the main line cable is increased to prevent slippage when clamping the branch line cable and the main line cable. This solves the problem of the cable not being securely fixed, causing the cable to loosen and fall off inside, resulting in damage and affecting the cable's service life.
