[0028] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0029] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the outline of the corresponding component. In addition, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] according to Figures 1 to 5 As shown, an embodiment of the present disclosure provides a wiring harness device for a dry-type transformer to reduce the electromagnetic interference of the wiring harness to the electronic equipment of the dry-type transformer. Specifically, the wiring harness device includes a box body, a cover body and a locking assembly. The box body includes a box body 1 and an inner lining box body 110. The box body 1 is formed with a groove for accommodating the inner lining box body 110. It can be understood that the inner lining box body 110 can be placed in the groove of the box body 1 or connected to the box body 1 by bolt connection. The present disclosure is not limited to this. The side wall of the box body is provided with a through hole 130 for accommodating the wiring harness. The cover body includes a cover body 2 and an inner lining cover body 210. The inner lining cover body 210 is connected to the cover body 2. For example, the inner lining cover body 210 and the cover body 2 can be connected by welding. The locking assembly is used to fix the box body and the cover body so that the inner lining cover body 210 and the inner lining box body 110 together form a shielding chamber 140 for accommodating the wiring harness.

[0031] Through the above technical solution, an inner lining box body 110 and an inner lining cover body 210 are added to the box body and the cover body to reduce the electromagnetic interference of the wiring harness, ensure that the electronic equipment or components of the dry-type transformer are in normal working condition, and enhance the safety and stability of the equipment; and by arranging the wiring harness in the shielding chamber 140, the loosening and damage to the wiring harness caused by external factors can be reduced, thereby improving the service life of the wiring harness.

[0032] Preferably, a rubber plug 131 may be provided at the through hole 130 to enhance the fixing effect of the wiring harness.

[0033] In order to enhance the shielding effect of the shielding chamber 140 against electromagnetic interference, the inner lining box body 110 and the inner lining cover body 210 can be constructed of metal materials, such as steel or iron. The present disclosure does not make any specific restrictions on this, as long as the function of reducing electromagnetic interference can be achieved.

[0034] The number of through holes 130 can be adjusted based on actual needs. For example, the number of through holes 130 can be two or four, and this disclosure does not specifically limit this. In some embodiments, there can be four through holes 130, i.e., two through holes 130 are provided on one side of the box body, and the other two through holes 130 are provided on the opposite side of the box body, so that four wire harnesses can pass through the through holes 130 on opposite sides of the box body and connect two by two within the shielding chamber 140.

[0035] In order to facilitate the maintenance of the wiring harness and the inspection of the interior of the box, in some feasible ways, for example, reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the locking assembly may include a first mounting hole 220, a second mounting hole 120, and a locking member 4. The first mounting hole 220 is provided on opposite sides of the cover body 2 along the first direction X, and the second mounting hole 120 is provided on opposite sides of the box body 1 along the first direction X. The positions of the first mounting hole 220 and the second mounting hole 120 correspond to each other. The locking member 4 is passed through the first mounting hole 220 and connected to the second mounting hole 120. The locking member 4 is detachable to achieve separation of the box body 1 and the cover body 2.

[0036] The structure of the locking member 4 can be adaptively adjusted according to actual conditions. For example, the locking member 4 can be configured as a screw, the first mounting hole 220 can be a through hole, and the second mounting hole 120 can be a screw hole. The screw is inserted from one side of the first mounting hole 220 and screwed into the second mounting hole 120 to fix the cover body 2 and the box body 1. It should be noted that the locking member 4 can also be configured as a bolt assembly, which is not specifically limited in this disclosure.

[0037] In order to strengthen the fastening degree between the liner cover 210 and the liner box body 110, in some practicable ways, for example, referring to Figures 1 to 3 As shown, the lining cover 210 may include a mounting portion 211, and the lining box body 110 may include a matching portion 111. The mounting portion 211 can be unlockably locked to the matching portion 111. By setting the mounting portion 211 and the matching portion 111, further fixation between the lining cover 210 and the lining box body 110 is achieved, thereby improving the stability of the shielding chamber 140.

[0038] Preferably, the mounting portion 211 may include a clamping block provided on the outer side walls of the lining cover 210 on opposite sides along the first direction X, and the matching portion 111 may include a clamping groove provided on the inner side walls of the lining box body 110 on opposite sides along the first direction X, and the clamping block and the clamping groove are clamped and matched to connect the lining cover 210 and the lining box body 110. It should be noted that, in this embodiment, the lining cover 210 may be constructed of a metal with elastic deformation, so that when the inner side wall of the lining cover 210 is subjected to force, the clamping block located on the outer side wall can be pushed to completely embed into the inner side groove.

[0039] In other alternative embodiments, the mounting portion 211 may include an elastic card block, which includes an inclined surface. The elastic card block may be configured so that when the inclined surface abuts the side wall of the lining box body 110, the elastic card block is forced to shrink to the inside of the lining cover body 210. The elastic card block may also be configured so that when the position of the elastic card block corresponds to the position of the card slot, the elastic card block can move toward the inside of the card slot so that the elastic card block and the card slot are locked together. It should be noted that, in order to facilitate disassembly, a push rod may be provided inside the card slot, which extends along the first direction X and passes through the side wall of the box body. By pressing the push rod, the push rod pushes the elastic card block to shrink to the inside of the lining cover body, thereby unlocking the elastic card block and the card slot.

[0040] The structural limitations of the mounting portion 211 and the mating portion 111 in the present disclosure are only for the purpose of the present disclosure. The structures of the mounting portion 211 and the mating portion 111 can be adaptively adjusted according to actual conditions. For example, one of the mounting portion 211 and the mating portion 111 can be an insert and the other can be a slot, and the connection and mating of the two can also be achieved. The present disclosure does not make any specific limitations on this.

[0041] In order to limit the position of the wire harness in the shielding chamber 140 and prevent the multiple wire harnesses from being entangled or rubbed. In some embodiments, for example, referring to Figures 1 to 4 As shown, the bottom wall of the lining box body 110 is formed with a wire groove 113 for placing the wire harness, and the interior of the lining cover body 210 can be provided with a wire pressing block 212, which is used to fix the wire harness located in the wire groove 113; the wire groove 113 is used to realize the displacement restriction of the wire harness along the first direction X, and the wire pressing block 212 is used to realize the displacement restriction of the wire harness along the second direction Y. In this way, the wire harness can be further fixed, and the stability of the wire harness device disclosed in the present invention can be enhanced.

[0042] In which, the wire trough 113 may include two partitions 112 arranged on opposite sides of the through hole 130 along the first direction X, and the length of the two partitions 112 along the third direction Z is smaller than the length of the lining box body 110 along the third direction Z, so that the gap between the partition 112 and the lining box body 110 forms an installation space 114, and the installation space 114 is used to install the adjustment component so as to further fix the lining cover 210 and the lining box body 110 and adjust the bending degree of the wiring harness through the adjustment component.

[0043] The partition 112 and the liner box body 110 may be constructed as a whole by injection molding, or may be connected by welding, but the present disclosure is not limited thereto.

[0044] It should be noted that the length limitation of the partition 112 and the liner box body 110 in the present disclosure is only for the purpose of the present disclosure. The length of the partition 112 and the liner box body 110 along the third direction Z can be adaptively adjusted according to actual conditions. For example, the length of the partition 112 along the third direction Z can be equal to the length of the liner box body 110 along the third direction Z, but the present disclosure is not limited to this.

[0045] In some embodiments, for example, referring to Figures 1 to 4 As shown, the wiring harness device may further include an adjustment component, which is disposed in the installation space 114. The adjustment component may include a first adjustment member 310 and a second adjustment member 320. The first adjustment member 310 is capable of pushing the inner lining cover 210 toward the first direction X to undergo elastic deformation, and is capable of pushing the second adjustment member 320 to move along the first direction X, so that the second adjustment member 320 is capable of pushing the wiring harness to bend. The bending of the wiring harness is achieved by the second adjustment member 320 to disperse and resist tensile force, reduce the risk of wiring harness breakage, and improve the tensile strength of the wiring harness. Further fixing the inner lining cover 210 and the inner lining box body 110 by the first adjustment member 310 is beneficial to preventing the separation of the inner lining cover 210 and the inner lining box body 110, making the shielding chamber 140 more reliable, so as to ensure that the electromagnetic interference shielding of the wiring harness is more complete.

[0046] In some embodiments, for example, referring to Figures 1 to 4 As shown, the first adjusting member 310 may include a rotating shaft 301 and a dial wheel 302. The dial wheel 302 can be rotatably connected to the rotating shaft 301 around its own central axis. The rotating shaft 301 extends along the third direction Z and passes through the side wall of the box body. In this way, it is convenient to manually rotate the rotating shaft 301 located outside the box body to adjust the dial wheel 302 located in the shielding chamber 140. The dial wheel 302 is used to push the lining cover 210 and the second adjusting member 320 to simultaneously realize the function of pushing the lining cover 210 and the second adjusting member 320, which is more convenient and quick.

[0047] The structure of the thumbwheel 302 can be adjusted adaptively according to actual conditions. Figures 1 to 4 As shown, the thumbwheel 302 can be constructed to include two toggle parts, which are respectively used to push the lining cover 210 and the second adjustment member 320. The present disclosure does not make any specific limitation on this, as long as its function can be achieved.

[0048] In order to facilitate the bending of the wire harness to improve the tensile strength of the wire harness, in some practicable ways, for example, referring to Figures 1 to 4As shown, the second adjusting member 320 may include a slider 303 and a guide seat 304. The guide seat 304 is arranged in the installation space 114. The slider 303 is movably connected to the guide seat 304 along the first direction X. The slider 303 is used to push the wire harness to bend, and the guide seat 304 is used to ensure the movement direction of the slider 303.

[0049] It is understood that in order to prevent the slider 303 from excessively moving, which could cause the slider 303 to separate from the guide seat 304 or excessively push the wiring harness, which could cause the wiring harness to break, a limit plate extending along the second direction Y can be provided on the top wall of the slider 303, for example, to limit the movement of the slider 303 and improve the safety of the second adjusting member 320.

[0050] In some embodiments, for example, referring to Figure 5 As shown, the first adjustment member 310 may include a switch assembly, which may include a gear 305, an adjustment screw 307, and a screw sleeve 306. The screw sleeve 306 is connected to the outer wall of the box body 1. The gear 305 is mounted on the rotating shaft 301 and is located outside the box body 1. The adjustment screw 307 is threadedly connected to the screw sleeve 306, so that rotating the adjustment screw 307 can drive the gear 305 to rotate, thereby driving the dial 302 located in the shielding chamber 140 to rotate about its central axis. The provision of the screw sleeve 306 and the adjustment screw 307 can further secure the box body 1 and the cover body 2. For example, the adjustment screw 307 may include a screw cap, which applies pressure to the cover body 2 to achieve securement. At the same time, the adjustment screw 307 can adjust the dial 302 in the shielding chamber 140, making manual operation more convenient.

[0051] It should be noted that the adjusting screw 307 can be fitted against the side walls of the cover body 2 and the box body 1 and screwed into the screw sleeve 306; or a circular hole for the adjusting screw 307 to pass through can be opened on the cover body 2, and the adjusting screw 307 passes through the circular hole and is threadedly connected to the screw sleeve 306. The present disclosure is not limited to this.

[0052] The present disclosure exemplarily describes the installation process of the wiring harness, for example: multiple wiring harnesses located on both sides of the box body are respectively passed through the through holes 130 on both sides of the box body, so that multiple wiring harnesses are located in the wire groove 113 of the shielding chamber 140, the wiring harnesses are connected in pairs to form a passage, the cover body is covered, so that the wire pressing block 212 presses the wiring harnesses located in the wire groove 113, and the locking piece 4 is installed to preliminarily fix the box body and the cover body; the adjustment screw 307 on the outside of the box body is turned into the screw sleeve 306, so that while further fixing the box body and the cover body, the dial 302 located in the shielding chamber 140 drives the slider 303 and the lining cover body 210 to move, thereby locking the lining cover body 210 and the lining box body 110 and the slider 303 pushing the wiring harness to bend, and the installation is completed.

[0053] The preferred embodiments of the present disclosure are described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple variations can be made to the technical solutions of the present disclosure, and these simple variations all fall within the scope of protection of the present disclosure. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner unless there is any contradiction.
