Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile domain controllers, in particular to a waterproof structure of a power connector of an automobile domain controller. Background Art
[0002] In order to realize various functions in the car, the number of electronic control components that cooperate with it has also increased, so the car domain controller is needed to realize the centralized control of the electronic control components. Since the car domain controller is installed in the passenger compartment or trunk of the car, when the cup / drink is knocked over and spilled, or when there is an umbrella with a large amount of rain, or when the car passes through a flooded area or washes the car, it is inevitable that water will splash onto the car domain controller. As an important component for supplying power to the domain controller, the waterproof performance of the power connector of the car domain controller is particularly important. Utility Model Content
[0003] The utility model discloses a waterproof structure of a power connector of a vehicle domain controller with good waterproof effect.
[0004] The power connector waterproof structure of the automobile domain controller described in the utility model comprises a domain controller housing, the domain controller housing is provided with a power slot for placing the power connector and a power cover covering the power slot, one side of the power slot is provided with a window for a wiring harness to pass through and connect with the power connector, a water guide groove is provided around the edge of the power slot on one side of the domain controller housing facing the power cover, and the power cover is provided with a brim extending in all directions and bent downwardly opposite to the water guide groove.
[0005] The waterproof structure of the power connector of the automobile domain controller is provided with a water guide groove for draining water at the edge of the power slot, and cooperates with the brim of the power cover to block water and guide water into the water guide groove, so as to effectively block and drain water droplets and prevent them from falling on the power connector. The structure is simple, the cost is low, and the waterproof effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] like Figure 1-4As shown, a waterproof structure of a power connector of a car domain controller includes a domain controller housing 1, the domain controller housing is provided with a power slot 2 for placing a power connector and a power cover 3 covering the power slot, one side of the power slot 2 is provided with a window for the wiring harness to pass through and connect with the power connector, the side of the domain controller housing facing the power cover is provided with a water guide groove 4 around the edge of the power slot, and the power cover is provided with a brim 301 extending in all directions and bending downward to be opposite to the water guide groove. By providing a water guide groove for draining water at the edge of the power slot, and cooperating with the brim of the power cover to block water and guide water into the water guide groove, water droplets are effectively blocked and drained away, and will not fall on the power connector, and the structure is simple, the cost is low, and the waterproof effect is good.
[0011] If the length of the brim is too long, it will interfere with the water guide groove. When the power cover is closed, the height of the power cover pressed down relative to the power slot will be limited, thereby affecting the sealing of the power cover covering the power slot. Therefore, a gap is left between the brim and the water guide groove to prevent the brim from interfering with the water guide groove when the power cover is closed, thereby avoiding the situation where the power cover cannot be sealed to cover the power slot.
[0012] The power cover is hingedly mounted on the domain controller housing on one side of the power slot. The power cover can be mounted on the domain controller housing on one side of the power slot via a rotating shaft, so that the power cover can rotate around the rotating shaft to close the power slot. At the same time, the power cover is connected to the domain controller housing via the rotating shaft, which can prevent the power cover from being easily lost due to its small size.
[0013] In order to improve the efficiency of installing the wire harness on the power connector, a fixing nut 5 for pressing the wire harness is also installed in the power slot. The wire harness can be pressed and fixed by the fixing nut, so that the wire harness can be quickly fixedly connected to the power connector.
[0014] The inner side of the power slot is provided with a locking protrusion 201, and the power cover is provided with a protrusion 302 that is engaged with the locking protrusion. Through the mutual cooperation between the locking protrusion and the protrusion, the power cover and the power slot can be covered more tightly, thereby improving the waterproof effect.
[0015] In order to ensure the sealing and waterproofness of the power cover and the power slot, an interference fit is required between the power cover and the power slot. Relying on the interference value between the power cover and the power slot, elastic pressure is generated between the contact surfaces of the power cover and the power slot after closing, thereby obtaining a tight connection. Therefore, the latch and the protrusion are provided with mutually matching inclined edges, and the inclined edges can act as a sliding guide, so that the power cover can be closed on the power slot more quickly, thereby improving installation efficiency.
