Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a new type of junction box structure. Background Art

[0002] The junction box is a common component used in the assembly process of general refrigerator-like household appliances such as wiring harness docking. Its function is to provide a space for organizing and placing the wiring harness terminals after docking, so as to facilitate the replacement of terminals during subsequent maintenance. Generally, the wiring harness of the junction box needs to be wrapped with sponge for sealing at the point where it enters the box. After the wiring harness is docked, it is arranged in a free state in the box. The wire box and the refrigerator and other shells are fixed with screws. Since the wire harness has no fixed constraints, there is a risk of breakdown. Moreover, this type of wire box is cumbersome and inefficient from wrapping the sponge around the wire harness to the final fixation. Since the junction box has the function of protecting the wiring harness terminals, if foaming liquid penetrates into the wire box, it will cause poor contact of the terminals and affect the normal operation of refrigerators and other appliances.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present invention.

[0037] The upper side and lower side of the box body 1 are respectively provided with an upper through hole 11 and a lower through hole 12 with the same inner diameter, a sleeve assembly 13 is fixedly installed in the upper through hole 11, and a bellows 14 is fixedly installed at the upper end of the lower through hole 12; the bellows 14 is provided to initially constrain the access wire harness; specifically, after the access wire harness is accessed to the bellows 14, the annular wavy step structure in the bellows 14 is closely attached to the outside of the access wire harness to ensure sealing;

[0038] The left side and the right side of the box body 1 are both provided with a side hole 15, and the side hole 15 has the same inner diameter as the upper through hole 11. A sealing cover 16 is provided in the side hole 15 for sealing the side hole 15. By providing the side hole 15, the wiring harness can be observed and adjusted when the wiring harness is connected. Since the sealing cover 16 is provided, the sealing cover 16 can be tightly placed in the side hole 15 after the adjustment is completed to ensure the sealing inside the box body 1.

[0039] At the same time, since the inner diameters of the side hole 15, the upper through hole 11 and the lower through hole 12 are the same, and the bellows 14 is installed at the upper end of the lower through hole 12, when the wiring harness is not connected through the bellows, the sealing cover 16 can be installed in the lower through hole 12 to seal the lower through hole 12; similarly, when the wiring harness is not connected through the sleeve assembly 13, the sealing cover 16 can be installed in the upper through hole 11 to seal the upper through hole 11; through these arrangements, the sealing inside the box body 1 can be ensured, and the foaming liquid can be effectively prevented from infiltrating;

[0040] The sleeve assembly 13 includes an inner tube 17 and an outer tube 18 sleeved outside the inner tube 17, and the outer tube 18 is fixed in the upper through hole 11, wherein the length of the inner tube 17 is greater than the length of the outer tube 18;

[0044] like Figures 6 to 8 As shown, two wire harness receivers 4 are installed in the box body 1;

[0045] The wire harness storage device 4 includes a bottom plate 41 and two arc-shaped snap rings 42 fixedly mounted on the front end of the bottom plate 41 and arranged opposite to each other. The other end of the arc-shaped snap ring 42 is bent outward to form a first bending portion 43, and the other end of the first bending portion 43 is bent outward to form a second bending portion 44.

[0046] A spring 45 is fixedly connected between the two first bending portions 43;

[0047] A connecting plate 46 is sleeved on the outside of the bottom plate 41, and the connecting plate 46 is fixedly installed in the box body 1;

[0048] The storage device is provided to store the connected wiring harness inside the box body 1; after the wiring harness is stored, it is compressed by the spring 45, so that not only the connected wiring harness can be tightened, but also adaptively adjusted according to the specifications of the connected wiring harness, which is suitable for actual use.

[0049] During actual use, the specific operation process is as follows: the access wiring harness can be accessed from the sleeve assembly 13 in the upper through hole 11, or from the corrugated tube 14 in the lower through hole 12. The access wiring harness in the access box body 1 passes through two arc-shaped clamping rings 42 and is fixed to the inside of the box body 1 via the arc-shaped clamping rings 42, thereby completing the installation and fixation of the access wiring harness.
