Description

Technical Field

[0001] The utility model belongs to the technical field of the shielding structure of the wiring harness in the cabinet, and more specifically, it relates to a top enclosing structure of the cabinet and a motor cabinet. Background Art

[0002] Places such as data centers and distribution substations that require a large number of electrical components are generally equipped with a large number of cabinets. Since there are many electrical components in the cabinet, not only do the electrical components need to be conductively connected to each other, but also to external electrical equipment and the like. In order to reduce the excessive space occupied by the wiring harness and to avoid accidentally touching the wiring harness and causing equipment abnormalities, the wiring harness entering the cabinet is usually distributed on the top of the cabinet. This situation often results in a large number of wiring harnesses distributed on the top of the cabinet, looking very messy.

[0003] In addition, in order to make a rational layout of the space, multiple cabinets are often arranged side by side. The sizes of cabinets for different purposes are mostly different, resulting in uneven heights of the entire row of cabinets and affecting the cleanliness of the appearance. Therefore, in order to keep the cabinet unified and clean, it is necessary to add an enclosure on the top of the cabinet. On the one hand, the enclosure can shield the wiring harness on the top of the cabinet, and on the other hand, it can also adjust the overall height of the cabinet through the enclosure, so that the tops of the cabinets in a row are on the same plane, improving the overall cleanliness.

[0004] However, the existing enclosures usually use bolts to connect multiple shielding plates end to end in sequence and then install the whole on the top of the cabinet. In the subsequent maintenance of the wiring harness inside when it is necessary to disassemble the enclosure, the enclosure needs to be separated from the cabinet as a whole. Not only is the disassembly inconvenient, but also it is very easy to interfere with the wiring harness during the process of taking out the enclosure, resulting in loose connections of the wiring harness. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a top enclosing structure of the cabinet and a motor cabinet, aiming to solve the problem in the prior art that after multiple shielding plates are connected to form an integral structure and then installed on the top of the cabinet, it needs to be removed as a whole during subsequent maintenance, and the disassembly and assembly are very inconvenient.

[0035] Please refer to Figures 1 to 6 , and now the cabinet top enclosure structure and the motor cabinet provided by the present utility model will be described. The cabinet top enclosure structure includes a support assembly, a baffle 2 and a connecting plate 3. The support assembly includes a plurality of support frames 1 spaced apart along a first path. The support frames 1 are used for connecting to the top of the cabinet body 4; the baffle 2 is connected to the support frames 1 and is used for shielding the support frames 1; the connecting plate 3 is connected to two adjacent support frames 1, and the baffle 2 and the connecting plate 3 enclose to form a shielding space.

[0036] The cabinet top enclosure structure provided by the present utility model, compared with the prior art, can first connect the support frame 1 to the top of the cabinet body 4 during installation. A plurality of support frames 1 are sequentially and spaced apart along a first path to form a support assembly. Then, the baffle 2 is connected to the same support frame 1 to shield the area corresponding to the support frame 1. After all the baffles 2 are installed, the connecting plate 3 is connected to two adjacent support frames 1 to further shield the space between the two adjacent support frames 1. Through the circumferentially enclosed shielding space formed by the baffle 2 and the connecting plate 3, the wire harness at the top of the cabinet body 4 is enclosed therein to prevent the wire harness from being exposed externally. In the cabinet top enclosure structure of the present utility model, the support frame 1 is used to fixedly install the baffle 2 and the connecting plate 3. Neither the connecting plate 3 nor the baffle 2 is directly connected to the cabinet body 4. When disassembly is required, only the corresponding baffle 2 or connecting plate 3 can be separated from the support frame 1 to maintain the wire harness therein, without disassembling the support frame 1, and the operation is simple. In addition, the support frame 1 can also provide a supporting force for the baffle 2 and the connecting plate 3, improving the strength and anti-deformation ability of the entire cabinet top enclosure structure.

[0037] In some embodiments, refer to Figures 1 to 2 , the support frame 1 includes a plurality of support members 101 spaced apart along a second path, and further includes a connecting member 102 sequentially connected to the plurality of support members 101. The second path is perpendicular to the first path, and both the baffle 2 and the connecting plate 3 are connected to the support member 101.

[0038] The connecting member 102 sequentially connects the plurality of support members 101 to form the overall support frame 1. The support member 101 is connected to the top of the cabinet body 4 to achieve connection with the cabinet body 4. After the baffle 2 is connected to the support member 101, the space between the plurality of support members 101 is shielded. In this embodiment, by setting the connecting member 102 to connect the plurality of support members 101 into an integral structure, on the one hand, it can be integrally installed on the cabinet body 4 after the support frame 1 is formed, simplifying the installation steps. On the other hand, it also increases the firmness and stability of the support frame 1, preventing the support member 101 from shifting after being subjected to an external force.

[0039] In some embodiments, refer to Figures 2 to 4 , the baffle 2 includes a shielding body 201 and a positioning member 203. The shielding body 201 is connected to the support member 101 for shielding the support frame 1. The positioning member 203 is connected to the inner side of the shielding body 201, and the positioning member 203 is provided with a positioning groove 2034 adapted to the connecting member 102, and the connecting member 102 is inserted into the positioning groove 2034.

[0040] When installing the baffle 2 and the support frame 1, the connector 102 is inserted into the positioning groove 2034, and then the baffle 2 is connected to the support 101. By plugging the connector 102 into the positioning groove 2034, it is not necessary to find the correct position during installation, which improves the installation efficiency, and the baffle 2 and the connector 102 can be limited by plugging, thereby improving the stability of the connection.

[0041] Optionally, the shielding body 201 is screwed or clamped to the support member 101 .

[0042] Optionally, the connecting member 102 is inserted into the positioning groove 2034 along the inner-outer direction or the upper-lower direction.

[0043] In some embodiments, see Figures 2 to 4 The baffle 2 also includes a limiting flange 202 connected to the top of the shielding body 201 , and the limiting flange 202 abuts against the top of the support member 101 .

[0044] When the baffle 2 and the support frame 1 are installed, the limiting flange 202 abuts against the top of the support member 101, thereby limiting the shielding body 201 in the up and down directions, thereby preventing the shielding body 201 from moving during the installation process and causing a decrease in the installation accuracy.

[0045] Optionally, corresponding connection holes are provided on the limiting flange 202 and the support member 101, and bolts are inserted into the connection holes.

[0046] Optionally, the positioning groove 2034 opens downward, and when installing the baffle 2, the baffle 2 is plugged into the support frame 1 from top to bottom until the connector 102 is inserted into the positioning groove 2034, and the limiting flange 202 abuts against the support 101. In this embodiment, the limiting flange 202 abuts against the support 101, and the connector 102 is inserted into the positioning groove 2034 to limit the baffle 2 in the up-down direction and in-outward direction, further improving the firmness after connection.

[0047] In some embodiments, see Figures 4 to 5 The positioning member 203 includes a connecting portion 2031 and reinforcing portions 2032 located on both sides of the connecting portion 2031 along the up and down directions. The connecting portion 2031 is connected to the shielding body 201, and the reinforcing portions 2032 protrude to the side away from the shielding body 201, and at least one of the reinforcing portions 2032 is provided with a positioning groove 2034.

[0048] The positioning member 203 is connected to the shielding body 201, which can improve the strength of the shielding body 201 and reduce the probability of the shielding body 201 deforming under force. In this embodiment, the connecting portion 2031 of the positioning member 203 realizes the connection with the shielding body 201, and the strengthening portion 2032 protrudes toward the side away from the shielding body 201, further increasing the strength and anti-deformation ability of the positioning member 203, so that the overall strength and stiffness of the baffle 2 formed after the positioning member 203 is connected to the shielding body 201 are better.

[0049] Optionally, the positioning member 203 is an integral member, and the strengthening portion 2032 can be formed by bending or stamping processes.

[0050] In some embodiments, please refer to Figure 6 , the positioning member 203 further includes a guiding inclined piece 2033 connected to the strengthening portion 2032. The guiding inclined piece 2033 is located at the open end of the positioning groove 2034, and the guiding inclined piece 2033 is used to guide the connecting member 102 to be inserted into the positioning groove 2034.

[0051] When the connecting member 102 is inserted into the positioning groove 2034, it first passes through the guiding inclined surface and enters the positioning groove 2034 under the guidance of the guiding inclined surface. The setting of the guiding inclined surface can enable the connecting member 102 to be quickly inserted into the positioning groove 2034 and improve the insertion speed.

[0052] Specifically, when the positioning groove 2034 has an opening in the up-down direction, the guiding inclined surface inclines toward the side away from the shielding body 201 to guide the connecting member 102 into the positioning groove 2034

[0053] In some embodiments, please refer to Figure 4 , the connecting member 102 includes a connecting body 1021 and fixed flanges 1022 provided at both ends of the connecting body 1021. The connecting body 1021 abuts against the support member 101 along the second path, and the fixed flanges 1022 are connected to the support member 101.

[0054] The setting of the fixed flanges 1022 increases the strength of the connecting member 102 on the one hand and reduces the probability of the connecting member 102 deforming under force; on the other hand, it increases the contact area with the support member 101, reduces the local pressure, and improves the firmness of the connection.

[0055] Optionally, the fixed flanges 1022 and the support member 101 are respectively provided with corresponding mounting holes, and locking bolts are inserted into the mounting holes.

[0056] Specifically, the fixed flanges 1022 are attached to the support member 101, and can be connected to the support member 101 by welding or bonding.

[0057] In some embodiments, please refer to Figure 5, the connecting body 1021 is a tubular structure, and a weight-reducing opening 1023 is provided on the inner side of the connecting body 1021.

[0058] In this embodiment, the connecting body 1021 is set as a tubular member. Compared with a plate-like member, its strength and stiffness are increased, and the tubular member is a hollow structure with a small weight, avoiding excessive pressure on the cabinet body 4. A weight-reducing opening 1023 is provided on the inner side of the connecting body 1021, which not only saves materials and reduces the weight of the connecting body 1021, but also does not affect the contact area with the baffle 2, avoiding the situation of excessive local pressure on the baffle 2.

[0059] In some embodiments, please refer to Figure 2 , reinforcing flanges 301 that bend inward are respectively provided at the top and bottom of the connecting plate 3, and the reinforcing flanges 301 abut against the top of the support frame 1.

[0060] The reinforcing flanges 301 can increase its strength without increasing the thickness of the connecting plate 3, avoiding the problem of excessive weight caused by the increase in the overall thickness of the connecting plate 3. At the same time, the reinforcing flanges 301 abut against the support frame 1 to limit the connecting plate 3 in the up and down directions. The firmness and stability of the connection between the connecting plate 3 and the support frame 1 are increased.

[0061] Based on the same inventive concept, the present utility model also provides an electric cabinet. Please refer to Figure 7 , the electric cabinet includes.

[0062] The electric cabinet provided by the present utility model adopts the above-mentioned cabinet top enclosure structure. During installation, the support frame 1 can be first connected to the top of the cabinet body 4, and a plurality of support frames 1 are sequentially spaced along a first path to form a support assembly. Then, the baffle 2 is connected to the same support frame 1 to shield the area corresponding to the support frame 1. After all the baffles 2 are installed, the connecting plate 3 is connected to two adjacent support frames 1 to shield the space between the two adjacent support frames 1. Through the circumferentially closed shielding space formed by the baffle 2 and the connecting plate 3, the wire harness at the top of the cabinet body 4 is enclosed therein, avoiding the exposure of the wire harness to the outside. In the cabinet top enclosure structure of the present utility model, the support frame 1 is used to fixedly install the baffle 2 and the connecting plate 3. The connecting plate 3 and the baffle 2 have no direct connection relationship with the cabinet body 4. When disassembly is required, only the corresponding baffle 2 or connecting plate 3 can be separated from the support frame 1 to maintain the wire harness therein, without disassembling the support frame 1, and the operation is simple. In addition, the support frame 1 can also provide a supporting force for the baffle 2 and the connecting plate 3, improving the strength and anti-deformation ability of the entire cabinet top enclosure structure.
