Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water pump terminal sealing plugs, in particular to a water pump terminal sealing plug. Background Art
[0002] Currently, water pumps are widely used in the water supply industry. They typically consist of a motor and a pump body. The motor is typically equipped with a controller to control the pump's operation, while the pump body consists of a casing and an impeller assembly housed within it. The motor drives the impeller in the impeller assembly to rotate, delivering water. With the continuous advancement of monitoring technology, water pumps are increasingly equipped with electrical components, all of which need to be connected to the controller.
[0003] Existing water pump terminals, such as the prior art with application number CN201821364604.4, include a motor, a pump body, a water inlet pressure sensor and a controller, etc., by correspondingly installing the terminals in the non-negative pressure water pump plug-in terminal on the motor and the pump body, wherein the signal output terminal is used to connect the pressure sensor and other detection components configured on the pump body, and the signal input terminal is connected to the controller on the motor.
[0004] However, in existing technologies, there is generally a gap between the terminals on the PCBA and the bottom cover, which requires a wiring harness to seal. However, during transportation or storage, water vapor may enter. After high-temperature operation, water vapor will condense, causing damage to PCBA components. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a water pump terminal sealing plug which ensures the sealing between the bottom cover and PCBA components during transportation and storage, is easy to install and has a simple structure.
[0006] The utility model discloses a water pump terminal sealing plug, comprising a bottom cover and a PCBC terminal; further comprising a sealing plug and an undercut, wherein the undercut is mounted on the sealing plug, and the sealing plug is mounted between the bottom cover and the PCBC terminal, so that the connection between the bottom cover and the PCBC terminal is sealed by the sealing plug; the connection between the bottom cover and the PCBC terminal is sealed by the sealing plug, thereby ensuring the sealing of the bottom cover and the PCBA components during transportation and storage.
[0007] Preferably, the sealing plug is installed between the bottom cover and the PCBC terminal; the above arrangement forms a seal, thereby ensuring the sealing between the bottom cover and the PCBC terminal during transportation and storage.
[0008] Preferably, the sealing plug and the bottom cover are in interference fit connection. With the above arrangement, after being installed in place, the sealing plug is sealed with both the terminal and the bottom cover, thereby preventing the intrusion of moisture from the outside.
[0009] Preferably, an undercut is installed on the sealing plug; the above arrangement ensures that the sealing effect can be ensured during transportation and storage, and the upper end of the sealing plug does not exceed the plane of the bottom cover, which does not affect the subsequent installation of the wiring harness.
[0010] Preferably, the sealing plug only needs to be installed on the PCBC terminal and positioned relative to the bottom cover; the above arrangement provides a simple structure, convenient installation, and can ensure the sealing of the entire structure.
[0011] Preferably, the sealing plug is of an integrated design; the above arrangement can ensure the sealing of the three terminals at the same time, and is simple and easy to install.
[0012] Compared with the prior art, the present invention has the following beneficial effects: the connection between the bottom cover and the PCBA terminal is sealed by the sealing plug, thereby ensuring the sealing of the bottom cover and the PCBA components during transportation and storage.

[0018] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.
[0019] Example 1
[0020] like Figures 1 to 4 As shown, a water pump terminal sealing plug includes a bottom cover 1 and a PCBC terminal 3, a sealing plug 2 and an undercut 4, the undercut 4 being mounted on the sealing plug 2, and the sealing plug 2 being mounted between the bottom cover 1 and the PCBC terminal 3, so that the connection between the bottom cover 1 and the PCBC terminal 3 is sealed by the sealing plug 2;
[0021] The sealing plug 2 is installed between the bottom cover 1 and the PCBC terminal 3;
[0022] The sealing plug 2 and the bottom cover 1 are in interference fit connection;
[0023] The sealing plug 2 is provided with an undercut 4;
[0024] The sealing plug 2 only needs to be installed on the PCBC terminal 3 and positioned with the bottom cover 1;
[0025] The sealing plug 2 is an integrated design;
[0026] The connection between the bottom cover 1 and the PCBA terminal 3 is sealed by the sealing plug 2 to ensure the sealing of the bottom cover and the PCBA components during transportation and storage.
