DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1, reference Figure 1 to Figure 2, which is the first embodiment of the present invention, provides a busbar protection device, including a protection mechanism 100, including a protective shell 101 and a connector 102 arranged on the protective shell 101, the connector 102 is used to control the opening and closing state of the protective shell 101; an isolation mechanism 200, which is arranged in the protective shell 101, the isolation mechanism 200 is used to isolate the busbar from the protective shell 101, it should be noted that the connector 102 is used to control the opening and closing state of the protective shell 101.

[0028] Specifically, the protective shell 101 includes a first shell 101a and a second shell 101b. The first shell 101a and the second shell 101b are integrally formed, and the protective shell 101 is made of soft material.

[0029] Furthermore, the protective shell 101 includes a first shell 101a and a second shell 101b, one side of the first shell 101a and one side of the second shell 101b are hinged, and the protective shell 101 is made of a hard material.

[0030] It should be noted that the contact plate 202 is in direct contact with the busbar, preventing the busbar from directly contacting the protective shell 101, thereby preventing the heat generated by the busbar after being powered on for a long time from causing the protective shell 101 to deform and twist, thereby causing damage to the protective shell 101 or oxidation damage to the busbar when exposed to the outside air. In addition, the presence of multiple sets of telescopic rods 201 can also adapt to busbars of different shapes and allow air circulation to help dissipate heat, further reducing the possibility of heat deformation of the protective shell 101

[0031] Example 2, reference Figures 1 to 4 This embodiment is different from the first embodiment in that: open grooves 101c are provided on both sides adjacent to the side where the first shell 101a and the second shell 101b are hinged; a connecting hole 101d is provided on the side of the first shell 101a away from the second shell 101b, and a rubber strip 101e is provided on the side of the first shell 101a away from the second shell 101b. It should be noted that the rubber strip 101e increases the friction of the contact surface, so that the protective shell 101 fits more tightly after closing.

[0032] Specifically, a protrusion is disposed at the center of the first shell 101a, and a cavity 101f is formed on a side of the protrusion close to the second shell 101b, and the isolation mechanism 200 is disposed in the cavity 101f.

[0033] Furthermore, the first shell 101a and the second shell 101b are opened as a whole, and the first shell 101a and the second shell 101b are mirror-imaged with adjacent sides as the central axis. It should be noted that the first shell 101a and the second shell 101b are opened as a whole, and are mirror-imaged with adjacent sides as the central axis, so that the protective shell 101 can be fully unfolded when opened, which is convenient for the installation and maintenance of the busbar; when closed, the two shells can fit tightly to ensure the safety and stability of the internal busbar.

[0034] The rest of the structure is the same as that of Example 1.

[0035] Example 3, reference Figures 1 to 4 This embodiment is different from the above embodiments in that: the isolation mechanism 200 includes a telescopic rod 201 arranged in the cavity 101f and a contact plate 202 arranged at the end of the telescopic rod 201, the telescopic rod 201 is provided with multiple groups of telescopic rods 201 and the same number of contact plates 202, and the contact plate 202 is used to contact the busbar.

[0036] Specifically, the connector 102 includes a locking rod 102a disposed on the outer wall of the second shell 101b and a pressing plate 102b disposed at the end of the locking rod 102a. The locking rod 102a can penetrate the connecting holes 101d on the first shell 101a and the second shell 101b at the same time.

[0037] Among them, an elastic rod 102c is arranged between the locking rod 102a and the pressing plate 102b. The elastic rod 102c can be extended and retracted. One end of the elastic rod 102c is connected to the pressing plate 102b, and the other end of the elastic rod 102c is connected to the end of the second shell 101b. The locking rod 102a passes through the elastic rod 102c.

[0038] Furthermore, a locking groove is provided at one end of the locking rod 102a away from the pressing plate 102b, a locking block 102d is provided in the locking groove, and the locking block 102d is connected to the locking groove through a spring; a curved surface is provided on one side of the locking block 102d away from the locking groove.

[0039] It should be noted that the opening grooves 101c arranged on the two adjacent sides of the side where the first shell 101a and the second shell 101b are hinged not only provide precise positioning guides for the busbar, ensuring that it is accurately placed inside the protective shell 101 during installation, but also allow partial air circulation to help dissipate heat, thereby reducing the risk of deformation of the protective shell 101 due to heating of the busbar. The design of the opening grooves 101c also helps to simplify the installation process of the busbar, making the operation more convenient.

[0040] The connecting hole 101d opened on the side of the first shell 101a away from the second shell 101b is used to cooperate with the locking rod 102a (as a part of the connecting piece 102) to achieve a firm locking between the first shell 101a and the second shell 101b. When the locking rod 102a passes through the connecting hole 101d, it can ensure that the protective shell 101 is stably fixed in a closed state. At the same time, the locking block 102d on the locking rod 102a can smoothly pass through the connecting hole 101d and automatically reset under the action of the spring. The cavity 101f formed by the protrusion arranged at the center of the first shell 101a close to the side of the second shell 101b is the placement space of the isolation mechanism 200. The isolation mechanism 200 is composed of multiple groups of telescopic rods 201 and contact plates 202 arranged at their ends. These contact plates 202 directly contact the busbar to isolate the busbar from the protective shell 101. This arrangement avoids the deformation and distortion of the protective shell 101 caused by the heat generated after the busbar is powered on for a long time, thereby avoiding damage to the protective cover or oxidation damage of the busbar when exposed to the outside air. In addition, the presence of multiple sets of telescopic rods 201 can also adapt to busbars of different shapes and allow air circulation to help dissipate heat, further reducing the possibility of heat deformation of the protective shell 101.

[0041] The rest of the structure is the same as that of Example 2.

[0042] Operation process: When the device needs to be used, first press the snap-fit ​​blocks 102d on both sides of the locking rod 102a to press the snap-fit ​​blocks 102d into the snap-fit ​​grooves, then separate the connecting hole 101d of the first shell 101a from the locking rod 102a, thereby separating it from the second shell 101b, and then place the busbar at the end of the first shell 101a or the second shell 101b. It is worth noting that both ends of the busbar need to be placed in the open groove 101c, which is conducive to positioning the busbar in the protective shell 101;

[0043] Then, the first housing 101a is rotated toward the second housing 101b until the first housing 101a and the second housing 101b are fitted together. At this time, the connecting hole 101d on the first housing 101a is connected with the connecting hole 101d on the second housing 101b. The locking rod 102a on the second housing 101b passes through the connecting hole 101d on the first housing 101a. When the locking rod 102a passes through the connecting hole 101d, the engaging block 102d on the side wall of the locking rod 102a is engaged by the connecting hole 101d. 1d moves toward the snap-fit ​​groove into the snap-fit ​​groove until the snap-fit ​​block 102d passes through the connecting hole 101d. At this time, the snap-fit ​​block 102d loses the squeeze force of the inner wall of the connecting hole 101d and returns to the initial state under the elastic force of the spring. At this time, the second shell 101b is locked with the first shell 101a through the snap-fit ​​block 102d on the locking rod 102a. At this point, the installation of the protective shell 101 and the busbar is completed. The device can use hard materials such as insulating materials such as plastics, or soft materials such as rubber.

[0044] It should be noted that, by arranging telescopic rods 201 and isolation plates in the cavities 101f of the first shell 101a and the second shell 101b, the busbar is not in direct contact with the protective shell 101, thereby avoiding the problem that the busbar generates a lot of heat after being powered on for a long time, and the protective cover is deformed and twisted due to the heat, causing damage to the protective cover, and the busbar is directly exposed to the outside air and directly contacts the busbar, causing oxidation damage. It should also be noted that the reason for using multiple groups of telescopic rods 201 is to adapt to different busbar shapes. At the same time, there are gaps between the multiple groups of telescopic rods 201, which are convenient for air circulation to dissipate heat and reduce the deformation and twisting of the protective cover due to heat. It should be noted that when using soft materials, the telescopic rod 201 should not be replaced with a telescopic spring rod or other similar support, because although the telescopic spring rod can achieve the purpose of isolation, its elastic force will cause the protective shell 101 of the soft material to deform.

[0045] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation changes, etc.) without materially departing from the novel teachings and advantages of the subject matter described in this application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise changed, and the nature or number of discrete elements may be changed.
