Detailed Implementation

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following is in conjunction with the appendix Figures 1-4 The energy storage battery connection device according to an embodiment of the present invention will be described in detail.

[0023] The energy storage battery connection device of this invention includes a positioning seat 2 and a connecting seat 3. There are two positioning seats 2, spaced apart in a first direction. The bottom of each positioning seat 2 has a groove 21 extending along the first direction, used to accommodate a connecting wire 1. Each positioning seat 2 also has a cutting groove extending vertically and communicating with the groove 21, used to accommodate a cutting blade 25. The cutting blade 25 is movable vertically to cut the connecting wire 1, and the vertical direction is orthogonal to the first direction. There are also two connecting seats 3, arranged one-to-one with the two positioning seats 2. Each connecting seat 3 is located at the bottom of the positioning seat 2 and is used to receive and hold the connecting wire 1 cut by the cutting blade 25. The bottom of each connecting seat 3 has a plug-in portion 314 for insertion and mating with an energy storage battery, and the plug-in portion 314 is electrically connected to the connecting wire 1.

[0024] The energy storage battery connection device of this invention provides a positioning seat 2 above the connecting seat 3. The two positioning seats 2 are arranged at intervals in the first direction, which facilitates the connection wire 1 to pass through the grooves 21 of the two positioning seats 2 in sequence. After stretching the connection wire 1 to determine the length of the connection wire 1 remaining between the two positioning seats 2, the cutting blade 25 in the positioning seat 2 is used to cut the connection wire 1 in the groove 21. After cutting, the connection wire 1 is moved into the connecting seat 3 below the positioning seat 2. The connection wire 1 is electrically connected to the energy storage battery through the connecting seat 3. Since the two positioning seats 2 and the two connecting seats 3 are set one-to-one, the cutting blade 25 in the positioning seat 2 is used to cut the connection wire 1 on site, so that the length of the cut connection wire 1 matches the required length between the two connecting seats 3, thereby achieving precise cutting of the connection wire 1 and improving installation accuracy.

[0025] Specifically, such as Figures 1-4 As shown, the connecting wire 1 extends along the first direction and passes through the grooves 21 of the two positioning seats 2 in sequence. The connecting wire 1 is a cable wrapped with an insulation layer. The main material of the positioning seats 2 is plastic or other insulating materials. The bottom side of the positioning seats 2 has a groove 21 that runs through the first direction. The connecting wire 1 passes through the groove 21. The groove 21 has a semi-circular arched cross section to facilitate the accommodation of the connecting wire 1.

[0026] Two positioning seats 2 are symmetrically arranged in the first direction. The positioning seat 2 is provided with a cutting groove extending downward from the upper end of the positioning seat 2 and communicating with the groove 21. The cutting blade 25 can move in the cutting groove in the vertical direction so that the cutting blade 25 can cut the connecting line 1 when it moves downward.

[0027] There are two connecting seats 3, each corresponding to one of the two positioning seats 2. The main material of the connecting seats 3 is also plastic or other insulating materials. The connecting seats 3 are located below the positioning seats 2, and the bottom of the connecting seats 3 is inserted into the energy storage battery. The connecting seats 3 are used to receive the connecting wires 1 cut by the positioning seats 2. When the connecting wires 1 are inside the connecting seats 3, the connecting wires 1 are electrically connected to the energy storage battery, realizing the electrical connection between the two energy storage batteries.

[0028] The bottom of the connector 3 is provided with a plug-in portion 314 for connecting and engaging with an energy storage battery. The plug-in portion 314 on the bottom of the connector 3 can be a socket, and the energy storage battery is provided with a plug that engages with the socket. Alternatively, the plug-in portion 314 on the bottom of the connector 3 can be a plug, and the energy storage battery is provided with a socket that engages with the plug, so as to realize the electrical connection between the energy storage battery and the connector 3.

[0029] In some embodiments, the top of the positioning seat 2 is provided with a suspension platform 22, and a threaded post 23 is threadedly engaged on the suspension platform 22. The lower end of the threaded post 23 is connected to the cutting blade 25 through a blade holder 24. The threaded post 23 can rotate in the up-down direction to drive the cutting blade 25 to move up and down.

[0030] Specifically, such as Figures 1-4 As shown, a suspension platform 22 is fixed to the top of the positioning seat 2. The suspension platform 22 is connected and suspended via a support frame. A threaded post 23 is threadedly connected to the suspension platform 22. The top of the threaded post 23 is hexagonal or other clampable shape, facilitating rotation of the threaded post 23. A cutter holder 24 is connected to the bottom of the threaded post 23. The cutter holder 24 is equipped with a cutting blade 25 for cutting the connecting line 1. The cutting blade 25 is located in a groove and can move downward along the groove to cut the connecting line 1 located in the groove 21. By controlling the downward movement of the cutting blade 25 through the threaded post 23, the rotational motion of the threaded post 23 is converted into the linear motion of the cutting blade 25. The displacement of the cutting blade 25 is precisely controlled by the thread pitch, achieving precise cutting. Moreover, the structure of the threaded post 23 is simple and reliable.

[0031] In some embodiments, the positioning seat 2 is provided with a support platform 26, which is movably disposed in the positioning seat 2 to close the lower end of the groove 21 so that the cutting blade 25 can cut the connecting line 1.

[0032] Specifically, such as Figures 1-4 As shown, the support platform 26 is laterally slidably disposed inside the positioning seat 2. The support platform 26 extends from one side of the positioning seat 2 and is guided to slide by the guide post. When the cutting blade 25 cuts the connecting line 1, the support platform 26 is slidably positioned on the bottom side of the connecting line 1 in the groove 21 by the sliding support platform 26, which facilitates the cutting blade 25 to cut the connecting line 1 in the groove 21.

[0033] Optionally, the top surface of the support platform 26 is also provided with a slot that is opposite to and communicates with the blade groove, so that the lower end of the cutting blade 25 can be inserted into the slot, thereby ensuring the complete and thorough cutting of the connecting line 1 while supporting the connecting line 1.

[0034] In some embodiments, each connector 3 includes a base 31 and two top half seats 32. The two top half seats 32 are both disposed on the base 31 and the two top half seats 32 can move closer to each other and further away from each other in a second direction so that the connecting line 1 cut by the cutting blade 25 can enter the connector 3. The second direction is orthogonal to the first direction and the up and down direction.

[0035] Specifically, such as Figures 1-4 As shown, both top half seats 32 are mounted on the base 31, and the positioning seat 2 is mounted on the top half seats 32. When the two top half seats 32 are far apart from each other, there is a preset distance between the two top half seats 32. The groove 21 of the positioning seat 2 is in communication with the base 31. The connecting wire 1 cut inside the positioning seat 2 can enter the base 31 through the gap between the two top half seats 32. After the connecting wire 1 enters the base 31, the positioning seat 2 can be removed from the two top half seats 32. The two top half seats 32 move closer to each other to clamp the connecting wire 1.

[0036] In some embodiments, the top of the base 31 is provided with a semi-groove 312, the bottom of the top half seat 32 is provided with an arc groove 321, the two top half seats 32 are far apart from each other so that the groove 21 communicates with the semi-groove 312, and the two top half seats 32 are close to each other so that the arc groove 321 and the semi-groove 312 cooperate to form a clamping hole for clamping the connecting line 1.

[0037] Specifically, such as Figures 1-4 As shown, the top two sides of the base 31 are provided with recessed grooves, and the bottom surface of the recessed grooves is provided with half grooves 312. The top half seat 32 is movably mounted on the recessed grooves in the second direction. The bottom side of the top half seat 32 is provided with an arc groove 321. The two top half seats 32 move closer to each other on the recessed grooves, so that the two arc grooves 321 and half grooves 312 close together to form a clamping hole that clamps the outside of the connecting line 1.

[0038] The top side of the top half seat 32 and the top side of the base 31 are respectively provided with embedding holes. The bottom side of the positioning seat 2 is provided with an embedding pin. When the positioning seat 2 is embedded in the top half seat 32 on the connecting seat 3, the groove 21 communicates with the half groove 312 and the groove 21 is located directly above the half groove 312. The two top half seats 32 are located on both sides below the groove 21. When the positioning seat 2 is removed from the top half seat 32, the two top half seats 32 move closer to each other so that the two arc grooves 321 and the half groove 312 close together to form a clamping hole that clamps the outside of the connecting line 1.

[0039] In some embodiments, the base 31 is provided with a metal sheet 313 that is vertically opposite to the cutting blade 25. The metal sheet 313 contacts the end of the connecting wire 1 in the clamping hole and is electrically connected to the plug-in portion 314.

[0040] Specifically, such as Figures 2-4 As shown, the metal sheet 313 is located on one side of the sink and directly below the cutting blade 25 so that the end of the connecting wire 1 contacts the metal sheet 313, thereby achieving an electrical connection between the connecting wire 1 and the metal sheet 313. The metal sheet 313 is electrically connected to the insertion part 314 at the lower end of the base 31, thereby achieving an electrical connection between the connecting wire 1 and the metal sheet 313.

[0041] For example, the metal sheet 313 is connected to the plug portion 314 via a wire harness.

[0042] In this embodiment, the energy storage battery connection device connects the connecting wire 1 through the grooves 21 of the two positioning seats 2, and connects the insertion part 314 of the connecting seat 3 to the terminals of the two energy storage batteries that need to be electrically connected. The positioning seat 2 and the connecting seat 3 are fitted together by the cooperation of the pin and the hole. The connecting wire 1 is stretched to determine the length of the connecting wire 1 remaining between the two connecting seats 3. The threaded column 23 is rotated to drive the cutting blade 25 to move downward to cut the connecting wire 1. After cutting, the connecting wire 1 is moved downward to fall into the half groove 312. The two positioning seats 2 are removed, and the two top half seats 32 are moved to close. At this time, the two ends of the connecting wire 1 are clamped by the two top half seats 32 and the base 31. The end of the connecting wire 1 contacts the metal piece 313 in the base 31, realizing the electrical connection between the two terminals of the two energy storage batteries.

[0043] Furthermore, the energy storage battery connection device determines and cuts the length of the connecting wire 1 between the two energy storage batteries to be connected on-site, and completes the connection with the connecting seat 3. Through the cooperation of the positioning seat 2 and the connecting seat 3, the length of the connecting wire 1 to be cut can be quickly determined, and the length of the connecting wire 1 can be finely adjusted. After the connecting wire 1 is cut by the cutting blade 25, the connecting wire 1 moves directly into the connecting seat 3 and is clamped and fixed, realizing the connection of the two poles of the energy storage battery. Moreover, it can be installed and cut on-site according to the poles of energy storage batteries with different interval lengths. It can be applied to determine the length of the connecting wire 1 for multiple energy storage batteries and connecting electrodes of different lengths on-site, reducing the waste of the length of the connecting wire 1 and reducing the problem of messy wire harness caused by the excessive length of the connecting wire 1 on-site, thus improving the installation accuracy.

[0044] In this embodiment, the energy storage battery connection device uses the positioning seat 2 to precisely cut the connecting wire 1 on-site. This allows for matching the thermal management spacing between energy storage batteries, improving installation accuracy. Furthermore, it avoids both the space occupation caused by redundant connecting wire 1 length and the need for rework and replacement due to excessively short connecting wire 1, thus preventing delays in the construction cycle. Through the cooperation between the positioning seat 2 and the connecting seat 3, this embodiment enables the precise-cut connecting wire 1 to be quickly moved into the connecting seat 3 for clamping and fixation. This adaptable design allows for electrical connections between different energy storage batteries, ensuring long-term operational reliability.

[0045] In some embodiments, the base 31 is further provided with a pressure seat 316, which is threaded onto the side of the metal sheet 313 away from the connecting line 1.

[0046] Specifically, such as Figures 2-4As shown, a pressure seat 316 is threadedly connected to the side of the base 31 away from the sink. A metal sheet 313 is fixed inside the pressure seat 316. By rotating the pressure seat 316, the metal sheet 313 is pressed tightly into contact with the end of the fixed connecting wire 1. By setting the pressure seat 316, a tight contact between the metal sheet 313 and the end of the connecting wire 1 can be ensured, thus guaranteeing the electrical connection function of the connecting wire 1.

[0047] In some embodiments, the energy storage battery connection device further includes a locking nut 4, a base 31 having a first extension 315 extending outward from the side of the half groove 312 away from the metal sheet 313, and a top half 32 having a second extension 322 extending outward from the side of the arc groove 321 away from the metal sheet 313, and the locking nut 4 can be sleeved on the first extension 315 and the second extension 322.

[0048] Specifically, such as Figures 2-4 As shown, the first extension 315 is a semi-cylindrical external threaded component, and the second extension 322 is a fan-shaped cylindrical external threaded component. After the two top half seats 32 move close together, the semi-cylindrical external threaded component and the fan-shaped cylindrical external threaded component close together to form a cylindrical external threaded component. A locking nut 4 is sleeved on the connecting line 1. The locking nut 4 is threadedly connected to the closed cylindrical external threaded component to clamp the connecting line 1.

[0049] Before the connecting line 1 is inserted into the two positioning seats 2, the locking nut 4 is pre-fitted onto the connecting line 1. By setting a semi-cylindrical external thread and a fan-shaped cylindrical external thread, and locking the semi-cylindrical external thread and the fan-shaped cylindrical external thread after they are closed, the firmness of the connecting seat 3 in clamping the connecting line 1 can be improved, and the structure and operation are simple.

[0050] In some embodiments, the top of the positioning seat 2 is also provided with a pressing post 27. The lower end of the pressing post 27 is fitted in the groove 21 and the pressing post 27 is movable in the up and down direction. The pressing post 27 is used to move the connecting line 1 in the groove 21 into the half groove 312.

[0051] Specifically, such as Figures 2-4 As shown, the pressing column 27 is vertically slidably mounted on the top of the positioning seat 2. The bottom end of the pressing column 27 is located on the top side of the connecting line 1 in the groove 21. By setting the pressing column 27, the connecting line 1 in the groove 21 can be quickly pressed down into the half groove 312 of the base 31.

[0052] In some embodiments, the upper end of the lower pressure column 27 is provided with a pressure block 271, the lower end of the lower pressure column 27 is provided with an arc-shaped block 273, and a spring 272 is provided between the pressure block 271 and the upper end surface of the positioning seat 2.

[0053] Specifically, such as Figures 2-4As shown, the top of the pressing column 27 is provided with a pressing block 271, and a spring 272 is provided between the pressing block 271 and the top side of the positioning seat 2. The bottom of the pressing column 27 is provided with an arc-shaped block 273 that contacts the top side of the connecting line 1. By setting the pressing column 27 with the spring 272, after the connecting line 1 is cut, the pressing column 27 moves downward, and the pressing column 27 drives the arc-shaped block 273 to move the connecting line 1 downward. The connecting line 1 can be quickly moved into the semi-groove 312, and the pressing column 27 can automatically rebound to ensure the subsequent connection between the connecting line 1 and the connecting seat 3, reducing the difficulty of operation.
