[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0026] Such as Figure 1 and Figure 5As shown in the figure, a quick-connecting cable for a power energy storage system includes a first cable 1 and a second cable 5. A fixed seat 2 is fixed to the right end of the first cable 1, and a power connection post 24 is fixed to the right end of the fixed seat 2. A power connection sleeve 6 sleeved on the power connection post 24 is fixed to the left end of the second cable 5. A socket seat 4 is sleeved on the outside of the power connection sleeve 6. Connecting members 3 fixedly connected to the fixed seat 2 are installed at positions near the left end on both the upper and lower sides of the socket seat 4. The connecting members 3 pull the socket seat 4 to the left. The leftward movement of the socket seat 4 drives the power connection sleeve 6 to tightly sleeve and fix the power connection post 24. When connecting the first cable 1 and the second cable 5, the power connection post 24 is inserted into the inside of the power connection sleeve 6 for socket connection, thereby achieving power connection. At this time, the fixed seat 2 and the socket seat 4 are fixedly connected through the connecting members 3. At the same time, the connecting members 3 pull the socket seat 4 to the left. The leftward moving socket seat 4 drives the power connection sleeve 6 to clamp the power connection post 24, making the power connection more stable and preventing poor contact.

[0027] As Figure 2 shown in the figure, the power connection sleeve 6 includes a conductive block 61. A plurality of clamping blocks 62 arranged uniformly in a circular shape are fixed to the left side of the conductive block 61. The outer side of the clamping block 62 is a tapered inclined surface 63. The clamping block 62 can be better clamped and driven in cooperation with the flared opening 42 through the inclined surface 63.

[0028] As Figure 3 shown in the figure, a socket opening 41 for sleeving with the plug 23 is provided at the left end of the socket seat 4. A flared opening 42 is provided on the right side of the socket opening 41. The structure of the flared opening 42 enables the socket seat 4 to move to the left, causing the plurality of clamping blocks 62 on the power connection sleeve 6 to clamp towards the middle, thereby sleeving and clamping and fixing the power connection post 24. A through hole for the insertion of the second cable 5 is provided on the right end face of the socket seat 4. A sealing sleeve 43 for sealing the inserted second cable 5 is fixed inside the through hole.

[0029] As Figure 3 shown in the figure, the connecting member 3 includes a hanging rod 31. The right end of the hanging rod 31 is rotatably connected to the socket seat 4. A locking block 33 is fixed to the left end of the hanging rod 31. A locking screw 32 is threadedly installed on the locking block 33. By rotating the hanging rod 31 and hanging it in the hanging groove 21 of the connecting plate 22, and then screwing the locking screw 32 to tighten against the connecting plate 22, the hanging rod 31 is tightened to pull the socket seat 4 to move to the left.

[0030] As Figure 4 shown in the figure, a plurality of annular ribs 431 are fixed to the outside of the sealing sleeve 43 for clamping and fixing during the installation of the sealing sleeve 43. A plurality of annular sealing ribs 432 are fixed in the inner hole of the sealing sleeve 43. The sealing sleeve 43 is sleeved on the second cable 5 through the sealing ribs 432 for sealing.

[0031] As Figure 5As shown in the figure, a plug 23 is fixed to the right end of the fixed seat 2 for positioning and plugging into the socket 41 of the socket 4. An annular connecting plate 22 is fixed to the outside of the plug 23. A hanging groove 21 for cooperating with the hanging rod 31 is provided on the outside of the connecting plate 22. The connecting plate 22 is hung with the hanging rod 31 through the hanging groove 21. The power connection post 24 is fixed to the right end of the plug 23, and the plug 23 fixes the power connection post 24.

[0032] In this embodiment, when connecting the first cable 1 and the second cable 5, the power connection post 24 is inserted into the inner hole between the plurality of clamping blocks 62. At the same time, the plug 23 is inserted into the socket 41. Then, the hanging rod 31 is rotated and hung in the hanging groove 21 of the connecting plate 22. Then, the locking screw 32 is screwed to press tightly against the connecting plate 22, so that the hanging rod 31 pulls the socket 4 to move leftward. The leftward moving socket 4 uses the cooperation between the flared opening 42 and the inclined surface 63 on the clamping block 62 to cause the plurality of clamping blocks 62 to contract toward the middle, thereby clamping the power connection post 24, and thus completing the rapid connection of the cable.

[0033] The above is the preferred embodiment of the present invention. Those skilled in the art of the present invention can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present invention belong to the protection scope of the present invention.
