Detailed ways

In order to make the above objectives, features and advantages of the present disclosure more comprehensible, specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

Example one:

This embodiment provides a terminal sealing device. Fig. 1 is a schematic structural diagram of a terminal sealing device provided by an embodiment of the present disclosure. Referring to FIG. 1, and in conjunction with FIGS. 2A-3, the structure shown in FIG. 1 will be described in detail.

In this embodiment, an air conditioner is taken as an example to illustrate the application scenario of the terminal sealing device. It is understandable that the terminal sealing device can also be used in other structures with sealing requirements.

As shown in FIG. 1, the terminal 11 is arranged on the first base 12 and a component is arranged on the second base 13. When the first base 12 and the second base 13 are combined, the terminal is connected to the component. In this embodiment, the terminal sealing device includes a sealing cover 1 and a terminal 2.

The sealing cover 1 is arranged on the first base 12. Specifically, a motor is provided on the first base 12, a space is formed between the terminal 11 and the motor, and the sealing cover 11 is provided on the first base 12 between the terminal 11 and the motor. When the first base 12 and the second base 13 are separated, the sealing cover 1 is used to seal the terminals 11 on the first base 12. Further, the contour edge of the sealing cover 1 should be consistent with the contour edge of the first base 12 to ensure the assembly effect.

The end 2 is connected to the sealing cover 1 at one end, and connected to the first base 12 at the other end, for fixing the sealing cover 1 and preventing the sealing cover 1 from falling out. When the first base 12 and the second base 13 are separated, the terminal 11 is exposed to the air. In order to prevent the terminal 11 from contacting with water, the sealing cover 1 and the terminal 11 are assembled for waterproofing, as shown in FIG. 2A; When the base 12 and the second base 13 are recombined, the sealing cover 1 is placed back on the first base 12, as shown in FIG. 1.

Taking an air conditioner as an example, the first base 12 is the lower base of the air conditioner, and the second base 13 is the upper base of the air conditioner. This component is an electric control box. A motor is installed on the lower base, and a space is formed between the motor and the terminal 11. The sealing cover 1 can be arranged in this space, for example, 3.5 mm from the left side of the terminal 11 to make full use of the space of the lower base. When the lower base and the upper base are combined, the terminal 11 is connected to the electric control box, and the sealing cover 1 is located in the space between the terminal 11 and the motor.

In this embodiment, the sealing cover 1 is provided with a groove 3 that is matched with the terminal 11, and the groove 3 is an interference fit with the terminal 11, and the amount of the interference fit is 0.1-0.3 mm.

2B, it can be seen that the sealing cover 1 is provided with a groove 3 where it is assembled with the terminal 11, and the groove 3 is consistent with the outer edge of the terminal 11, so that the groove 3 and the terminal 11 are matched. When the first base and the second base are separated, the terminal 11 is inserted into the groove 3 of the sealing cover 1, so that the assembly between the terminal 11 and the sealing cover 1 is tight, and the water path between the terminal 11 and the sealing cover 1 is lengthened, and further Improved waterproof effect.

The size of the groove 3 in the sealing cover 1 should be smaller than the size of the terminal 11 with which it is matched. An interference fit is formed between the groove 3 and the terminal 11, which makes the assembly between the sealing cover 1 and the terminal 11 tighter and has a better waterproof effect. it is good. In addition, the amount of interference fit between the groove 3 and the terminal 11 is 0.1-0.3 mm, that is, the size of the groove 3 is smaller than the size of the terminal 11 by 0.1-0.3 mm, so as to ensure that the groove 3 and the terminal 11 are easy to assemble.

In this embodiment, the sealing cover 1 is made of elastic material. The sealing cover 1 made of elastic material can make the assembly between the sealing cover 1 and the terminal 11 closer, and when the first base 12 and the second base 13 are in a combined working state, the sealing cover 1 made of elastic material The abnormal noise and noise generated by the friction between the first base 12 and the sealing cover 1 can be reduced, and the user experience and comfort can be improved. The elastic material is, for example, rubber. Those skilled in the art can obtain other elastic materials according to the description of this embodiment.

In this embodiment, the end 2 is a fishbone structure, the first base 12 is provided with a hole 14, and the end 2 of the fishbone structure is connected to the first base 12 through the hole 14, as shown in FIG. 3. The end 2 and the hole 14 form a fit, so that the position of the sealing cover 1 is fixed, and it is not easy to fall off, which prevents interference when the first base 12 and the second base 13 are combined. Further, the front end of the fishbone structure is set as the lead-in structure.

The fishbone structure refers to a structure with a narrow middle of the end 2 and a wider front and rear ends. The narrow part in the middle is assembled with the hole 14, which can effectively prevent the assembly failure between the end 2 and the hole 14, and avoid the end Head 2 falls off. The front end of the tip 2 adopts an introduction structure, which makes the assembly between the tip 2 and the hole 14 easier. The introduction structure is, for example, a structure that gradually widens from the front end to the middle of the end head 2 shown in FIG. 3, and the end head 2 is also made of elastic material to ensure that its front end can pass through the hole 14.

Taking an air conditioner as an example, the end is located 46mm to the left of the terminal 11, 27mm in front of the sealing cover 1, between the water receiving tray and the terminal 11, and adjacent to the stepping motor hole on the left side of the air guide.

In this embodiment, by providing a terminal sealing device on the first base, when disassembling the first base and the second base, the terminal is sealed with a sealing cover to prevent water from entering the terminal to avoid short circuit of the connected components. The sealing cover The groove is provided to form an interference fit with the terminal to improve the waterproof effect. The end of the fishbone structure is used to form a fit with the hole on the first base to prevent the end from falling off and fix the position of the sealing cover.
