[0070] like Figures 1 to 4 As shown, the utility model provides a housing 10 of a bus duct, and the housing 10 is in a long strip shape, so as to be applied to a straight-through bus duct, such as a slide-rail straight-through bus duct. Figure 5 and Figure 6 The overall structure of the bus duct 1 is shown. The housing 10 may include a housing top wall 11, a housing side wall 30 and a bracket portion 40. The housing side walls 30 are located on both sides of the housing top wall 11 in the width direction, serving as the external part of the housing 10. The bracket portion 40 is arranged inside the housing 10, in other words, as the internal part of the housing 10, for fixing a plurality of conductors 20. The plurality of conductors 20 may include, for example, a phase conductor 21 (L), a neutral conductor 22 (N) and a protective conductor 23 (PE). The number of phase conductors 21 may be three, with one neutral conductor 22 and one protective conductor 23. Optionally, these conductors 20 may all be copper conductors. The bracket portion 40 is located between the housing side walls 30 on both sides and is connected to the housing top wall 11. The housing side walls 30, the housing top wall 11 and the bracket portion 40 constitute the main body of the housing 10.

[0071] It should be noted that the directional terms used in this article, such as "top", "bottom", "upper", "lower", "vertical", "horizontal direction", etc., are relative to the direction of the Figure 1 This is for the housing 10 which is shown in an upright position.

[0072] In this embodiment, if Figures 2 to 4 As shown, the bracket portion 40 is integrally connected to the housing top wall 11. In this way, the main body of the housing 10 can be formed into an integral piece using the same material, which can simplify the structure of the housing 10 and reduce the manufacturing cost. For example, the main body can be made of aluminum profile.

[0073] The bus duct 1 also needs to use a plug-in box to distribute electrical energy. In order to achieve the locking connection between the bus duct 1 and the plug-in box, the plug-in box is provided with a movable locking foot, and the shell side wall 30 is provided with a structure for clamping. Specifically, the shell side wall 30 includes an upper side wall portion 31 extending vertically, a protrusion 32 for clamping with the locking foot of the plug-in box, and a lower side wall portion 35 extending vertically. The protrusion 32 is bent outward from the bottom end of the upper side wall portion 31 and connected to the top of the lower side wall portion 35. In this arrangement, the structural strength at the protrusion 32 is high, and the lower side wall portion 35 can provide support to the protrusion 32 when the protrusion 32 is clamped with the plug-in box, so that the connection between the shell 10 of the bus duct 1 and the plug-in box is more stable and reliable. The shell side wall 30 is symmetrically arranged relative to the shell top wall 11.

[0074] The bracket portion 40 is provided with a plurality of receiving grooves 43, the receiving grooves 43 are used to receive the conductors 20 and have a groove bottom wall 44, and the groove bottom wall 44 is provided with a bottom wall opening 45. The conductors 20 can be installed in the receiving grooves 43 and supported by the groove bottom wall 44. When the plug-in box is locked on the bus duct 1, the pins of the plug-in box can be inserted through the bottom wall opening 45 to contact and connect with the conductors 20.

[0075] The raised portion 32 may include a holding wall 33 and a connecting wall 34. The holding wall 33 extends in the horizontal direction and is connected to the bottom end of the upper side wall portion 31, and the connecting wall 34 is at least partially bent inwardly from the outer end of the holding wall 33 in a downwardly inclined manner and is connected to the top end of the lower side wall portion 35. Exemplarily, the connecting wall 34 may first extend vertically and then bend inwardly, that is, be partially bent inwardly; alternatively, the connecting wall 34 is directly bent inwardly from the outer end of the holding wall 33, that is, be completely bent inwardly.

[0076] The bracket portion 40 can be spaced apart from the side wall 30 of the housing in the width direction so that there is a gap between the two. The bracket portion 40 includes a first bracket portion 41 for fixing the phase conductor 21 and the neutral conductor 22, and the receiving grooves 43 of the first bracket portion 41 are arranged side by side. Optionally, the sizes of the respective receiving grooves 43 are the same. Adjacent receiving grooves 43 share a vertical groove wall. Such an arrangement can simplify the structure of the housing 10, facilitate production and manufacturing, and reduce production and manufacturing costs. The housing 10 also includes a plurality of insulating components 50 for accommodating the conductor 20, and each insulating component 50 is correspondingly arranged in the receiving groove 43 in the first bracket portion 41. The insulating component 50 has an insertion port 52, and the insertion port 52 corresponds to the position of the bottom wall opening 45. The insulating component 50 can isolate the conductor 20 from the main body of the housing 10 to avoid leakage.

[0077] The insulating member 50 has an extension wall 51, which is arranged opposite to each other to form an insertion port 52, and the extension wall 51 extends out of the receiving groove 43 from the bottom wall opening 45. The extension wall 51 can prevent the pins from contacting the main body of the housing 10 at the bottom wall opening 45 to prevent leakage, and the extension wall 51 can guide the insertion of the pins, making it easier to install the plug box on the bus duct 1.

[0078] The bracket part 40 also includes a second bracket part 42 for fixing the protective conductor 23. No insulating member 50 is provided in the receiving groove 43 of the second bracket part 42, and the protective conductor 23 is directly placed in the receiving groove 43 and directly supported on the bottom wall 44 of the groove. Thus, the bottom wall opening 45 is an insertion port 52. The second bracket part 42 is spaced apart from the first bracket part 41 in the width direction, so that there is a gap between the two. Optionally, the receiving groove 43 of the second bracket part 42 is different from the receiving groove 43 of the first bracket part 41 in cross-sectional dimensions at least in the height direction. And the receiving groove 43 of the second bracket part 42 is different from the receiving groove 43 of the first bracket part 41 in position at least in the height direction. Such a configuration can be applicable to protective conductors 23 with cross-sectional dimensions different from those of the phase conductors 21 and the neutral conductors 22, so that the application environment of the bus duct 1 is more targeted. Figure 4 It is schematically shown that the bottom end of the second bracket part 42 is higher than the bottom end of the second bracket part 42, and the position of the receiving slot 43 of the former in the height direction is higher than the position of the receiving slot 43 of the latter in the height direction. This can be applied to the pins of the protective conductor 23 with a larger pin length that matches the phase conductor 21 and the neutral conductor 22.

[0079] like Figure 5 and Figure 6 As shown, in addition to the conductor 20 and the housing 10, the bus duct 1 of the utility model further includes plugs 60 located at both ends of the housing 10 in the length direction and a lower cover plate 70 located at the lower side of the housing 10. The plug 60 can block the end opening formed at the end of the housing 10, and each conductor 20 extends from the plug 60. The lower cover plate 70 can cover the bottom opening formed at the bottom side of the housing 10. The lower cover plate 70 is provided with an opening (not shown) for facilitating the plugging of the pins of the plug box.

[0080] like Figure 4 and Figure 6 As shown, in order to fix the plug 60, a first fixing hole 36 is provided at the corner formed by the top wall 11 of the housing and the upper side wall portion 31. The first fixing hole 36 is used to fix the plug 60 located at the end of the housing 10. Specifically, a fastener such as a screw can be first passed through the through hole of the plug 60 and then tightened into the first fixing hole 36, so that the plug 60 can be fixed at the top. A fixing portion 38 with a second fixing hole 37 is formed at the bottom end of the lower side wall. The fixing portion 38 protrudes outward from the bottom end of the lower side wall or protrudes outward and inward. Figure 4 The fixing portion 38 is schematically shown to protrude outward. The second fixing hole 37 is used to fix the plug 60 located at the end of the housing 10. Specifically, a fastener such as a screw can be first passed through the through hole of the plug 60 and then tightened into the first fixing hole 36, so that the plug 60 can be fixed at the bottom. In this embodiment, the four corners of the plug 60 are fixed to the housing 10.
