The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0053] like Figure 1-Figure 14 As shown, the distribution box according to the embodiment of the first aspect of the utility model includes: a non-metallic box body 10, a metal part 60 and a plurality of high-voltage cables 50.

[0054] Each high voltage cable 50 includes a shielding layer 53 .

[0055] The metal member 60 is located on the inner side or the outer side of the non-metal box body 10 , and each shielding layer 53 is conductively connected to the metal member 60 .

[0056] It should be noted that in practical applications, Figure 5As shown, each high-voltage cable 50 includes a conductor 51, an insulating layer 52, a shielding layer 53, and a sheath layer 54, which are arranged in sequence from the inside to the outside. Among them, the shielding layer 53 can be an aluminum foil shielding layer and a braided shielding layer. The cross-section of the conductor 51 is circular, and the cross-sections of the insulating layer 52, the shielding layer 53, and the sheath layer 54 are all annular, so that the insulating layer 52 covers the conductor 51, the shielding layer 53 covers the insulating layer 52, and the sheath layer 54 covers the shielding layer 53. A branch shielding body 55 is provided on the shielding layer 53, and the branch shielding body 55 extends to the external environment through the sheath layer 54. Among them, the cross-section of the branch shielding body 55 can be annular, and the cross-section of the branch shielding body 55 can also be circular,...

[0057] The non-metal box body 10 may be a plastic box body, an acrylic box body, a rubber box body, a wooden box body, etc., which are not listed one by one in this embodiment. Such a configuration can reduce the overall weight of the distribution box on the one hand, solve the problem that the distribution box in the related art uses metal materials to achieve shielding conduction, resulting in a bulky distribution box, and on the other hand, reduce the production cost of the distribution box.

[0058] The metal part 60 may be a metal part 60 made of copper material, the metal part 60 may be a metal part 60 made of aluminum material, the metal part 60 may be a metal part 60 made of iron material, ..., which are not listed one by one in this embodiment.

[0059] The metal member 60 may be disposed on the inner side of the non-metal box body 10 , or the metal member 60 may be disposed on the outer side of the non-metal box body 10 , and the metal member 60 is connected to the non-metal box body 10 .

[0060] Each branch shielding body 55 is conductively connected to the metal member 60, which can be understood as follows: in one embodiment, each branch shielding body 55 is directly conductively connected to the metal member 60; in another embodiment, Figure 6 As shown, two branch shielding bodies 55 form a shielding unit body 501, and the shielding unit body 501 is conductively connected to the metal part 60; in another embodiment, three branch shielding bodies 55 form a shielding unit body 501, and the shielding unit body 501 is conductively connected to the metal part 60; in yet another embodiment, four branch shielding bodies 55 form a shielding unit body 501, and the shielding unit body 501 is conductively connected to the metal part 60; ..., these embodiments are not listed one by one.

[0061] It should be noted that at least two branch shielding bodies 55 form a shielding unit body 501, and the shielding unit body 501 is conductively connected to the metal member 60. This can reduce the number of shielding grounding structures, thereby reducing the number of shielding grounding operations, and helping to reduce the labor intensity of assembly personnel.

[0062] In summary, in this embodiment, each shielding layer 53 is conductively connected to the metal part 60 to achieve shielding grounding of each high-voltage cable 50. The shielding grounding structure is simple and easy to operate. The setting of the non-metallic box body 10 can, on the one hand, reduce the overall weight of the distribution box and solve the problem that the distribution box in the related technology uses metal materials to achieve shielding conduction, which makes the distribution box bulky. On the other hand, it can reduce the production cost of the distribution box.

[0063] Preferably, two adjacent branch shielding bodies 55 form a shielding unit body 501 .

[0064] Specifically, Figure 8 , 9 As shown, eight high-voltage cables 50 are provided on the distribution box: the first high-voltage cable 50a to the eighth high-voltage cable 50h, the first high-voltage cable 50a is provided with a first branch shielding body 55a, the second high-voltage cable 50b is provided with a second branch shielding body 55b, the third high-voltage cable 50c is provided with a third branch shielding body (blocked, not shown), the fourth high-voltage cable 50d is provided with a fourth branch shielding body (blocked, not shown), the fifth high-voltage cable 50e is provided with a fifth branch shielding body (blocked, not shown), the sixth high-voltage cable 50f is provided with a sixth branch shielding body (blocked, not shown), the seventh high-voltage cable 50g is provided with a seventh branch shielding body (blocked, not shown), and the eighth high-voltage cable 50h is provided with an eighth branch shielding body (blocked, not shown).

[0065] The distribution box is formed with four shielding units 501. Figure 6 As shown, the first branch shielding body 55a and the second branch shielding body 55b are adjacent to each other, and the two form a shielding unit body 501. The shielding unit body 501 can be located between the first branch shielding body 55a and the second branch shielding body 55b, which helps to make the length of the first branch shielding body 55a and the length of the second branch shielding body 55b equal, thereby making the structure of the first high-voltage cable 50a and the structure of the second high-voltage cable 50b the same, so that each high-voltage cable 50 can be a standard part, reducing the structural types of the high-voltage cable 50, and helping to reduce production costs. In addition, the two adjacent branch shielding bodies 55 can minimize the length of each branch shielding body 55 to the greatest extent, thereby avoiding waste of the branch shielding body 55.

[0066] Similarly, the adjacent third branch shielding body and the fourth branch shielding body form a shielding unit body 501, wherein the length of the third branch shielding body and the length of the fourth branch shielding body can be equal. The adjacent fifth branch shielding body and the sixth branch shielding body form a shielding unit body 501, wherein the length of the fifth branch shielding body and the length of the sixth branch shielding body can be equal. The adjacent seventh branch shielding body and the eighth branch shielding body form a shielding unit body 501, wherein the length of the seventh branch shielding body and the length of the eighth branch shielding body can be equal.

[0067] Furthermore, the shielding unit body 501 is conductively connected to the metal member 60 through the wire nose 70. In detail, the shielding unit body 501 formed by the adjacent first branch shielding body 55a and the second branch shielding body 55b is used as an example:

[0068] like Figure 3 , 4 As shown, the adjacent first branch shielding body 55a and the second branch shielding body 55b form a shielding unit body 501, and the cross section of the shielding unit body 501 is a circle with a plurality of hollow areas, such as Figure 7 As shown. A wire nose connection hole 123 is provided on the non-metallic box body 10. The wire nose 70 includes an annular portion 71 and a mounting hole 72, the mounting hole 72 corresponds to the wire nose connection hole 123, and a first fastener (such as a bolt or a screw) passes through the mounting hole 72 and is threadedly connected to the wire nose connection hole 123, so that the wire nose 70 is fixedly connected to the non-metallic box body 10.

[0069] The shielding unit body 501 is arranged on the inner circle of the annular portion 71, and the outer circle of the annular portion 71 is crimped to make the inner circle of the annular portion 71 interference fit with the shielding unit body 501. This increases the contact area between the shielding unit body 501 and the annular portion 71, so that the two are in full contact, and at the same time improves the connection strength and connection reliability between the annular portion 71 and the shielding unit body 501, so that the shielding unit body 501 is not easy to detach from the annular portion 71, thereby improving the shielding grounding stability of the high-voltage cable 50.

[0070] Furthermore, if Figure 7 As shown, the outer side of the shielding unit body 501 is covered with a protective layer 502. The protective layer 502 is an insulating material, for example, the insulating material can be an insulating tape. The insulating material can protect the shielding unit body 501 to prevent accidental damage to the shielding unit body 501 when the annular portion 71 is connected to the shielding unit body 501.

[0071] In some embodiments of the present utility model, the non-metallic box body 10 includes an upper cover 11 and a lower box body 12, the upper cover 11 is provided with a first matching portion, the lower box body 12 is provided with a second matching portion, the first matching portion and the second matching portion are inserted or snap-fitted, so that the upper cover 11 covers the opening of the lower box body 12. In this way, the upper cover 11 and the lower box body 12 are assembled without fasteners, so that the assembly between the two is simple and convenient, and the assembly efficiency of the non-metallic box body 10 is improved.

[0072] In some embodiments of the utility model, a third matching portion 1111 is provided on the upper cover 11, and a fourth matching portion 1211 is provided on the lower box body 12. The third matching portion 1111 and the fourth matching portion 1211 are connected by a connecting member 40 so that the upper cover 11 covers the opening of the lower box body 12.

[0073] In a specific embodiment, Figure 2 As shown, a plurality of upper bosses 111 are convexly provided on the outer surface of the upper cover 11, and the plurality of upper bosses 111 are arranged circumferentially around the upper cover 11. A third matching portion 1111 is provided on each upper boss 111. A plurality of lower bosses 121 are convexly provided on the outer surface of the lower box body 12, and the lower bosses 121 correspond to the upper bosses 111 one by one, and the plurality of lower bosses 121 are arranged circumferentially around the lower box body 12. A fourth matching portion 1211 is provided on each lower boss 121.

[0074] like Fig.11 , 12 As shown, the third matching portion 1111 and the fourth matching portion 1211 are both second grooves (or second through holes). The connector 40 may be a dovetail clip, on which an upper elastic portion 41 and a lower elastic portion 42 are provided. The upper elastic portion 41 is snapped to the third matching portion 1111, and the lower elastic portion 42 is snapped to the fourth matching portion 1211. With such a configuration, the upper cover 11 and the lower box body 12 are not assembled using fasteners, so that the assembly between the two is simple and convenient, and the assembly efficiency of the non-metal box body 10 is improved. At the same time, the production cost of the distribution box is reduced.

[0075] Of course, it can be understood that the third matching part 1111 and the fourth matching part 1211 are both third through holes, and the connecting member 40 is a second fastener with a nut. The second fastener passes through the third matching part 1111 and the fourth matching part 1211, and the second fastener and the nut thereon enable the upper cover 11 to cover the opening of the lower box body 12.

[0076] Further, such as Figure 2 As shown, a first sealing ring 30 is provided between the openings of the upper cover 11 and the lower box body 12. This arrangement improves the sealing performance of the distribution box and prevents the external environment from affecting the inside of the distribution box. For example, the first sealing ring 30 allows the distribution box to meet the IP67 protection level.

[0077] In some embodiments of the present invention, a metal component mounting portion 122 is provided on the outer surface of the box wall of the non-metal box body 10 , and the metal component mounting portion 122 mounts the metal component 60 so that the metal component 60 is located outside the non-metal box body 10 .

[0078] It should be noted that in practical applications, Figure 2 As shown, a circuit board 20 is arranged inside the non-metal box body 10, and an AC relay, a low-voltage connector, etc. are welded on the circuit board 20. The metal part 60 is arranged outside the non-metal box body 10, which helps to increase the space inside the non-metal box body 10, thereby facilitating the arrangement of various cables on the circuit board 20, making the cable arrangement neat and simple, and avoiding the entanglement and crossing of the cables.

[0079] In a specific embodiment, Fig. 9 As shown, the metal member 60 is disposed at the bottom of the non-metal box body 10. The metal member 60 is a plate. The outer surface of the bottom wall of the lower box body 12 is recessed to form a first groove, and the first groove is the metal member mounting portion 122 mentioned above. The first groove is adapted to the outer contour of the metal member 60 so that the first groove and the metal member 60 are inserted and matched. At the same time, Fig.13 , 14 As shown, a first protrusion 124 is formed by protruding from the bottom of the first groove, a first through hole 61 through which the first protrusion 124 can pass is provided on the metal member 60, and a stopper 1241 is formed at the end of the first protrusion 124 by melting, bending, welding, etc., and the stopper 1241 is engaged with the first through hole 61. In this way, the metal member 60 can be stably connected to the non-metal box body 10, and at the same time, the metal member 60 is prevented from additionally increasing the external dimensions of the non-metal box body 10, which is conducive to the miniaturization design of the non-metal box body 10.

[0080] Of course, it is understandable that the outer surface of the box side wall of the lower box body 12 may also be recessed to form the above-mentioned first groove.

[0081] Furthermore, if Figure 2 As shown, a plurality of connecting parts 62 are provided on the metal member 60, and the connecting parts 62 correspond to the shielding unit bodies 501 one by one. Figure 4 As shown, the first fastener (e.g., a bolt or a screw) passes through the mounting hole 72 and the connecting portion 62 in sequence and is threadedly connected to the wire nose connecting hole 123, so that the metal part 60 is fixedly connected to the non-metallic box body 10, further improving the connection strength of the metal part 60.

[0082] Further, the lower box body 12 has a receiving cavity for receiving the circuit board 20. A fourth through hole (not shown) is provided on the box wall of the lower box body 12, and the fourth through hole connects the receiving cavity and the external environment. One end of the high-voltage cable 50 passes through the fourth through hole and is electrically connected to the circuit board 20. A sealing member 80 is filled between the fourth through hole and the high-voltage cable 50 to ensure a sealing fit between the fourth through hole and the high-voltage cable 50.

[0083] Specifically, Figure 2 As shown, eight fourth through holes are provided on the side wall of the lower box body 12. The first high-voltage cable 50a to the eighth high-voltage cable 50h correspond to a fourth through hole respectively. Take the fourth through hole corresponding to the first high-voltage cable 50a (or the second high-voltage cable 50b) as an example:

[0084] The opening edge of the fourth through hole toward the external environment extends outward to form an annular cylinder 125, and two second protrusions 1251 arranged opposite to each other are provided on the outer ring of the annular cylinder 125. The gland 90 includes a cover plate 92 and two arc plates 91 arranged opposite to each other. The cover plate 92 is provided with a wire hole 921 through which the first high-voltage cable 50a (or the second high-voltage cable 50b) can pass, and the arc plate 91 is arranged along the axial direction of the wire hole 921 and connected to the same side of the cover plate 92. A card slot 911 is provided on the arc plate 91, and the card slot 911 is adapted to the second protrusion 1251 so that the two are inserted and matched.

[0085] The sealing member 80 may be a second sealing ring, which is sleeved on the first high-voltage cable 50a. Fig.10 As shown, when the first high-voltage cable 50a with the second sealing ring passes through the annular cylinder 125, the second sealing ring can be located inside the annular cylinder 125. The gland 90 is coaxially arranged with the annular cylinder 125, the first high-voltage cable 50a passes through the wire hole 921 on the cover plate 92, and the card slot 911 is inserted and matched with the second protrusion 1251, so that the gland 90 and the annular cylinder 125 are firmly connected together. This arrangement can prevent water and dust from the external environment from entering the interior of the non-metallic box body 10 from the gap between the first high-voltage cable 50a and the annular cylinder 125, avoiding affecting the normal operation of the circuit board 20. At the same time, the insertion and fitting (or snap fit) between the gland 90 and the annular cylinder 125 is convenient and simple to operate, which greatly saves the assembly cost of the non-metallic box body 10.

[0086] In addition, if Figure 8As shown, 8 terminals are provided on the circuit board 20: the first terminal 21 to the eighth terminal 28, the first terminal 21 corresponds to the first high-voltage cable 50a, and the first high-voltage cable 50a passes through its corresponding annular cylinder 125 to be electrically connected to the first terminal 21. The second terminal 22 corresponds to the second high-voltage cable 50b, and the second high-voltage cable 50b passes through its corresponding annular cylinder 125 to be electrically connected to the second terminal 22. Among them, the direction from the first terminal 21 to the annular cylinder 125 corresponding to the first high-voltage cable 50a is parallel to the direction from the second terminal 22 to the annular cylinder 125 corresponding to the second high-voltage cable 50b.

[0087] Similarly, the direction of the annular cylinder 125 corresponding to the third terminal 23 to the third high-voltage cable 50c, the direction of the annular cylinder 125 corresponding to the fourth terminal 24 to the fourth high-voltage cable 50d, the direction of the annular cylinder 125 corresponding to the fifth terminal 25 to the fifth high-voltage cable 50e, and the direction of the annular cylinder 125 corresponding to the sixth terminal 26 to the sixth high-voltage cable 50f are all parallel to each other.

[0088] Similarly, the direction of the annular cylinder 125 corresponding to the seventh terminal 27 and the seventh high-voltage cable 50g is parallel to the direction of the annular cylinder 125 corresponding to the eighth terminal 28 and the eighth high-voltage cable 50h.
