DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
[0027] In the following description, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. The following description provides a plurality of embodiments of the present application, and different embodiments can be replaced or combined, so that the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B and C, and another embodiment includes features B and D, the present application should also be considered to include one or more embodiments of all other possible combinations of A, B, C and D, although the embodiment may not be explicitly described in the following content.
[0028] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this application. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.
[0029] Example 1: As Figs. 1 to 6 As shown, this utility model provides a box cover structure, including a support part 1 and a cover 2. The support part 1 includes a flange 12 connected to the box body 3 and a support frame disposed on the flange 12. The support frame includes a front support 111 and a rear support 112 respectively disposed at both ends of the flange 12. The cover 2 is disposed on the side of the support part 1 away from the box body 3. The cover 2 covers the box body 3 by covering the front support 111 and the rear support 112. The cover 2 is an integrally formed heat shrinkable part.
[0030] In this utility model, a box cover structure is prepared and installed on the box body 3. The box cover structure includes a support part 1 forming a support frame and a cover cloth 2 set on the support part 1. The support part 1 is set on the box body 3 and forms a support space for the installation of the box module. Finally, a cover cloth 2 is placed on the upper side of the support part 1 to cover the box body 3 and form a sealed structure to protect the box module. The heat dissipation of the box module during operation is completely achieved through water cooling on the side and bottom of the box body 3, so that the upper side of the box body 3 can still dissipate heat even when it is covered.
[0031] First, the structure of the support unit 1 includes a flange 12 connected to the insert box body 3 and a support frame disposed on the flange 12. The flange 12 is actually a rectangular flange frame that fits with the edge of the insert box body. The support frame is then disposed within the flange frame. The support frame includes a front support 111 and a rear support 112 disposed at both ends of the flange 12. Both the front support 111 and the rear support 112 extend away from the insert box body 3, i.e., protrude upwards (generally U-shaped or C-shaped pieces with downward openings). Thus, when the flange 12 is installed on the insert box body 3, the front support 111 and the rear support 112 form an arched space on the basis of the insert box body 3, which facilitates the installation of modules on the insert box body 3.
[0032] Then the cover cloth 2 is set on the side of the support part 1 away from the box body 3 of the plug-in box, that is, after the support part 1 is installed on the box body 3 of the plug-in box, the cover cloth 2 is directly covered on the upper side of the support part 1, the edge of the cover cloth 2 is connected with the flange 12, and the middle part of the cover cloth 2 is between the front support 111 and the rear support 112. The cover cloth 2 forms an arched cover structure under the support of the front support 111 and the rear support 112, and the module is covered inside.
[0033] Here, the cover cloth 2 is an integrally formed heat shrinkage part, and the cover cloth 2 is made of heat shrinkage material. Heat is generated during the charging and discharging process of the plug-in box. The heat shrinkage part shrinks under heat, is stretched into a plane by the fixing and stretching of the front support and the rear support, and the flatness is improved. Compared with the CTR plug-in box without a box cover, when condensation, collision, fire, and injection of fire-fighting medium occur, the cover cloth 2 can protect the modules and electrical components in the plug-in box and prevent damage to the exposed modules and electrical components. Compared with the box cover made of sheet metal, pressure plastic, and suction plastic, the material cost of the cover cloth 2 and the support part 1 in the present application is low, no mold manufacturing cost is needed, the overall cost of the PACK is reduced, the supply cost is reduced to improve market competitiveness, the purchase cost is reduced, and the construction cost is reduced. Moreover, when the module is out of control, when the temperature exceeds the solidification temperature of the heat shrinkage material, the heat shrinkage material gradually solidifies, finally becomes solid, and has sufficient strength, preventing the heat shrinkage box cover from bulging, deforming, and breaking after solidification.
[0034] Embodiment two: still as Figs. 1 to 6 shown, only one embodiment of the present application, on the basis of embodiment one, in the present application, the end plate 117 is arranged on the front support 111 and the rear support 112, the functional panel 115 and the maintenance window 116 are arranged on the end plate of the front support 111, the front support 111 is used for fixing the maintenance window 116 and the functional panel 115, and the total positive terminal, the total negative terminal, the MSD, the communication connector, and the fire-fighting connector installed on the maintenance window and the functional panel are prevented from being recessed into the plug-in box, the relative position is ensured, and installation, maintenance and the like are facilitated. Of course, the maintenance window can also be arranged on the end plate of the rear support 112 for maintenance.
[0035] In this way, the end plates on the front support 111 and the rear support 112 seal the front and rear ends of the plug-in box cover, and the cover cloth 2 only needs to close the two sides and the top surface of the box cover.
[0036] In the utility model, the front support 111 and the rear support 112 are provided with the isolation support 113, actually the isolation support 113 is arranged at the position of the one side of the front support 111 close to the rear support 112 and a certain distance from the front support 111, at least a part of the isolation support 113 is located in the plug-in box body 3, the isolation support 113 is a vertically arranged rectangular frame, the bottom of the isolation support 113 extends to the bottom of the plug-in box body 3, the plug-in box body 3 is connected and fixed with the isolation support 113 through connecting bolts or connecting buckles, the isolation support 113 is provided with a limiting clamping groove, and the module wire head in the plug-in box body 3 can be installed in the limiting clamping groove.
