The accommodating cavity may include a mounting cavity 101 and a routing cavity 102, a first side of the routing cavity 102 is communicated with the mounting cavity 101, a second side of the routing cavity 102 is communicated with the outside of the housing 100, the first side and the second side of the routing cavity 102 are opposite sides, the circuit assembly 200 includes an electrical element 210 and a cable 220, the electrical element 210 is disposed in the mounting cavity 101, a first end of the cable 220 is electrically connected with the electrical element 210, a second end of the cable 220 extends out of the outside of the housing 100 through the routing cavity 102, and the routing cavity 102 is filled with a sealing medium.

It can be understood that the installation cavity 101 and the routing cavity 102 are two relatively independent spaces, the cable 220 in the installation cavity 101 needs to pass through the routing cavity 102 when being led out, the routing cavity 102 plays an isolating role between the external space of the shell 100 and the installation cavity 101, and meanwhile, the isolating effect of the routing cavity 102 is improved by utilizing a sealing medium, so that external dust, water drops or refrigerant is prevented from entering the installation cavity 101 during routing, damage to electric elements is avoided, and the working reliability and the service life of the electric control box are improved.

It should be noted that, the routing chamber 102 may be located at one side of the installation chamber 101, for example, may be located at an upper side, a lower side, a left side or a right side of the installation chamber 101, or the routing chamber 102 may be located at multiple sides of the installation chamber 101, for example, the routing chamber 102 may be disposed around the installation chamber 101, and a location of the routing chamber 102 may be designed according to an extraction position and an extraction direction of the cable 220 when the electric control box is applied, which is not specifically limited in the embodiment of the present utility model.

The manner in which the sealing medium in the trace chamber 102 is filled will be described in detail first.

With continued reference to fig. 1-4, in one possible implementation, the sealing medium may encapsulate the cable 220 penetrating the routing chamber 102, so that the sealing medium may perform a sealing and isolating function on a position where the cable 220 passes, and the sealing medium may perform an isolating or absorbing function on flowing media such as dust, water drops, and refrigerant, so as to isolate a flow path thereof.

It can be understood that the sealing medium may be a fixed medium, or may be a fluid medium that forms a fixed medium after being injected, so that the sealing medium can improve the tightness of the wiring position of the cable 220 on the one hand, and can improve the stability of the arrangement of the cable 220 on the other hand, avoid the cable 220 from moving in series, and improve the stability and reliability of the connection of the cable 220 after the electric control box is installed, so as to avoid the cable 220 from being disconnected from the electric element 210 after the electric control box is stressed outside.

In some embodiments, the sealing medium may be a foaming medium, that is, the sealing medium may be injected into the routing chamber 102 through a foaming process, and expand and compress the cable 220 passing through the routing chamber 102 in the routing chamber 102, where the housing 100 has a foaming hole 1211 opposite to the routing chamber 102, and after the circuit assembly 200 is assembled and the cable 220 is connected, the sealing medium is injected into the routing chamber 102 through the foaming hole 1211, so that the sealing medium may form a good sealing structure, and may fill the internal space of the routing chamber 102 in a wide range, thereby improving the sealing performance.

The sealing medium may be a foaming sponge, and the specific material parameters and foaming process of the foaming sponge are not particularly limited in the embodiment of the utility model.

It should be noted that, after the sealing medium is filled into the routing chamber 102 through foaming, the sealing medium may be filled into a space in part of the routing chamber 102 or may be filled into a space in the routing chamber 102, for example, when the space in the routing chamber 102 is partially filled, the sealing medium may be disposed around the cable 220 after foaming to wrap the cable 220, so as to play a sealing effect, and when the sealing medium is filled into the space in the routing chamber 102, the shape presented by the sealing medium may be matched with the outline shape of the routing chamber 102, so as to play an isolating and sealing effect on each area.

In addition, by using the foaming sponge as a sealing medium, not only good isolation effect is achieved on water drops, dust, refrigerants and the like, but also the weight of the electric control box can be reduced while good filling tightness is achieved, and the installation stability of the electric control box is improved.

The specific routing of the cable 220 through the routing chamber 102 is described in detail below.

For example, when the axis of the first via hole 111 and the axis of the first via hole 111 are offset from each other, the projections of the first via hole 111 and the second via hole 112 along the axial directions thereof may partially overlap, so that when the cable 220 is threaded in the routing cavity 102, the bending angle of the cable 220 is smaller, and the cable 220 is prevented from being bent excessively and failing.

In one possible implementation, the mounting cavity 101 and the routing cavity 102 may be arranged along the length direction of the housing 100, and the dimensions of the mounting cavity 101 and the routing cavity 102 along the width direction of the housing 100 are matched, so that the cables 220 may be selectively led out from different positions of the mounting cavity 101, thereby improving the convenience of the layout of the electrical components 210 inside the mounting cavity 101.

It will be appreciated that the routing chamber 102 may be disposed below the mounting chamber 101, and the whole of the electronic control box may be disposed vertically, so that the cable 220 is led out from the bottom of the housing 100, thereby preventing dust or water drops from penetrating from the outside due to gravity, for example, the axes of the first and second via holes 111 and 112 may extend in the vertical direction.

In some embodiments, the hole wall of at least one of the first via hole 111 and the second via hole 112 may be provided with a sealing portion configured to be attached to the outer wall of the cable 220 and wrap the outer wall of the cable 220 at the corresponding position, wherein the hole wall of the first via hole 111 may be provided with a sealing portion, or the hole wall of the second via hole 112 may be provided with a sealing portion, or the hole walls of the first via hole 111 and the second via hole 112 are provided with sealing portions, so that the tightness between the first via hole 111 and the second via hole 112 and the cable 220 may be improved.

It is understood that the sealing portion may have elasticity, when the cable 220 passes through the first wire passing hole 111 and the second wire passing hole 112, the cable 220 may press the sealing portion to generate elastic deformation, so that the sealing portion has a pretightening force when being attached to the outer wall of the cable 220, in addition, the sealing portions of each of the first wire passing hole 111 and the second wire passing hole 112 may be plural, and plural sealing portions are disposed around the cable 220, so that the sealing portions are sealed at various positions in the circumferential direction of the cable 220.

For example, the sealing portion may be made of a material such as silica gel or rubber, which is not limited in the embodiment of the present utility model, when the cable 220 is not inserted, the first via hole 111 and the second via hole 112 may be sealed by the sealing portion, and adjacent sealing portions may be mutually spliced together or only a small gap is reserved.
