Obviously, the drawings in the following description are some embodiments of this application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0025] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0026] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprise" indicate the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0027] It should also be understood that the terms used in this specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. As used in this specification of this application and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0028] It should also be further understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In addition, in the present application, unless otherwise clearly specified or limited in the embodiments, the terms "installed", "connected", "coupled", "fixed", etc. appearing in the embodiments should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or integrated. Understandably, it can also be a mechanical connection, an electrical connection, etc.; of course, it can also be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two components, or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific implementation situations.

[0030] In the related art, when removing metal or non-metal particles on the surface of a connector, mainly the methods of blowing off with air flow or washing with liquid water are adopted. However, when cleaning by blowing off with air flow, it will cause the metal or non-metal particles to float, which may further cause secondary pollution, resulting in the final cleanliness of the connector not meeting the requirements; when cleaning by washing with liquid water, it is relatively difficult to dry the connector after washing, and it will also cause the insulation impedance of the plastic parts of the connector to decrease, thereby causing adverse phenomena such as electrical short circuits.

[0031] Therefore, the present application provides a cleaning system for a connector, which includes a cleaning device 100 and a drying device 200. The cleaning device 100 is configured to ultrasonically clean the connector with a hydrocarbon solvent, and the drying device 200 is configured to vacuum negative pressure dry the connector after vacuum ultrasonic cleaning. Thus, not only can the metal or non-metal particles on the surface of the connector be better removed, but also during the process of cleaning the connector, product deformation can be avoided, and at the same time, all relevant characteristics of the connector are maintained, thereby enhancing the value of the product, and the yield rate of the product is very high, which is beneficial to large-scale mass production.

[0032] Please refer to Figure 1 , Figure 1 which is a schematic block diagram of the connector and the cleaning system provided by the embodiment of the present application. As Figure 1 shown, the present application provides a cleaning system for a connector, which includes:

[0033] A cleaning device 100, configured to ultrasonically clean the connector with a hydrocarbon solvent;

[0034] A drying device 200, configured to vacuum negative pressure dry the connector after vacuum ultrasonic cleaning.

[0035] In this embodiment, the connector can be cleaned one or more times by ultrasonic cleaning in the cleaning device 100 using a hydrocarbon solvent. Specifically, vacuum ultrasonic cleaning can be used, and the hydrocarbon solvent can be decane. The content of decane in the hydrocarbon solvent needs to reach more than 99%. Thus, metal particles or non-metal particles on the surface of the connector can be removed, enabling the surface of the connector to meet the cleanliness standards of VDA19.1, VDA19.2, and ISO16232. At the same time, it can also ensure that the connector does not deform during the cleaning process.

[0036] Meanwhile, after the connector is ultrasonically cleaned in the cleaning device 100, a drying device 200 can be used for vacuum negative pressure drying. Specifically, a hydrocarbon cleaning device can be used for vacuum negative pressure drying to achieve low-temperature drying of the connector, so that the electrical, mechanical, and environmental properties of the connector will not change. This improves the quality and yield of the product and is conducive to large-scale production.

[0037] In addition, before ultrasonic cleaning the connector with a hydrocarbon solvent, the present application can also perform vacuum flipping on the connector. After vacuum flipping, the connector is ultrasonically cleaned with a hydrocarbon solvent, which can further improve the cleanliness of the connector after vacuum negative pressure drying. The cleaning system for the connector provided in the present application includes a cleaning device 100 and a drying device 200. The cleaning device 100 is configured to ultrasonically clean the connector with a hydrocarbon solvent, and the drying device 200 is configured to perform vacuum negative pressure drying on the connector after vacuum ultrasonic cleaning. Thus, not only can the removal of metal or non-metal particles on the surface of the connector be better completed, but also product deformation can be avoided during the cleaning process of the connector. At the same time, all relevant characteristics of the connector are maintained, thereby enhancing the value of the product. The yield of the product is very high, which is conducive to large-scale production.

[0038] In some embodiments, as Figure 1 shown, the cleaning system further includes:

[0039] A filtration system 300, which is connected to the cleaning system and is configured to filter the hydrocarbon solvent after cleaning the connector;

[0040] A recovery system 400, which is connected to the cleaning system; the recovery system 400 is configured to recover the filtered hydrocarbon solvent and transport the recovered hydrocarbon solvent to the cleaning system.

[0041] In this embodiment, the filtration system 300 can filter the hydrocarbon solvent after cleaning the connector in the cleaning device 100, and after the filtration is completed, input it back into the cleaning device 100 to achieve cyclic cleaning of the connector, so as to ensure that the cleanliness of the finally cleaned connector can meet the cleanliness standards of VDA19.1, VDA19.2, and ISO16232.

[0042] Meanwhile, the present application is also equipped with a recovery system 400 in the cleaning system, which can perform distillation purification on the hydrocarbon solvent after cleaning the connector in the cleaning device 100, and input the distilled and purified hydrocarbon solvent back into the cleaning system to further achieve cyclic cleaning of the connector, so as to further ensure that the cleanliness of the finally cleaned connector can meet the cleanliness standards of VDA19.1, VDA19.2, and ISO16232.

[0043] In some embodiments, as Figure 2 shown, the cleaning device 100 is provided with a cleaning tank 110, the connector is placed in the cleaning tank 110, and ultrasonic cleaning is performed using the hydrocarbon solvent.

[0044] In this embodiment, the hydrocarbon solvent can be placed in the cleaning tank 110, the connector can be immersed in the hydrocarbon solvent in the cleaning tank 110, and at least one ultrasonic transducer 500 can be provided at the bottom of the cleaning tank 110, so as to achieve ultrasonic cleaning of the connector in the cleaning tank 110. Meanwhile, the cleaning tank 110 can be vacuum-sealed with a sealing cover to achieve vacuum ultrasonic cleaning of the connector.

[0045] In some embodiments, as Figure 2 shown, a separator 120 is provided in the cleaning tank 110, and the separator 120 is configured to divide the cleaning tank 110 into a first cleaning area 111 and a second cleaning area 112. The first cleaning area 111 is configured to perform ultrasonic cleaning on the connector using the hydrocarbon solvent, and the second cleaning area 112 is communicated with the filtration system 300 and the drying system respectively.

[0046] In this embodiment, the separator 120 can be a partition board, which can divide the cleaning tank 110 into two areas, namely the first cleaning area 111 and the second cleaning area 112. The ultrasonic transducer 500 can be arranged in the first cleaning area 111. At the same time, the connector can be placed in the first cleaning area 111 for ultrasonic cleaning. At the same time, the second cleaning area 112 can be respectively communicated with the filtration system 300 and the drying system, and the hydrocarbon solvent in the first cleaning area 111 can be transported to the second cleaning area 112, so as to realize the recovery and filtration of the hydrocarbon solvent in the cleaning device 100, so as to realize the circulating cleaning of the connector, so as to ensure that the cleanliness of the finally cleaned connector can meet the cleanliness standards of VDA19.1, VDA19.2, and ISO16232.

[0047] In some embodiments, as Figure 2 shown, the second cleaning area 112 is provided with a first liquid outlet 1122, and the first liquid outlet 1122 is arranged at the bottom of the second cleaning area 112 and is communicated with the filtration system 300.

[0048] In this embodiment, the filtration system 300 is respectively communicated with the first cleaning area 111 and the first liquid outlet 1122. After the hydrocarbon solvent in the first cleaning area 111 reaches a certain height, it can overflow to the second cleaning area 112 through the separator 120. The hydrocarbon solvent in the second cleaning area 112 can enter the filtration system 300 through the first liquid outlet 1122, and after being filtered by the filtration system 300, it is transported to the first cleaning area, so as to realize the circulating cleaning of the connector.

[0049] In some embodiments, as Figure 2 shown, the first liquid outlet 1122 is located above the bottom of the first cleaning area 111. Specifically, the cleaning tank 110 is designed in a stepped manner, and at the same time, the separator 120 can divide the cleaning tank 110 at the step to realize dividing the cleaning tank 110 into two areas.

[0050] In some embodiments, as Figure 2 shown, the filtration system 300 includes a filter and a circulation pump 301; wherein, one end of the filter is communicated with the first liquid outlet 1122, the other end of the filter is communicated with one end of the circulation pump 301, and the other end of the circulation pump 301 is communicated with the first cleaning area 111.

[0051] In this embodiment, the filter can be a Y-type filter 3021, which can be arranged between the first liquid outlet 1122 and the circulation pump 301. At the same time, a U-type filter 3022 can also be arranged between the circulation pump 301 and the first cleaning area 111, so as to further ensure that the purified hydrocarbon solvent can be circularly injected into the first cleaning area 111 to realize the circular cleaning of the connector.

[0052] In some embodiments, as Figure 2 shown, the filtration system 300 further includes a first solenoid valve 303 and a second solenoid valve 304; wherein, one end of the first solenoid valve 303 is respectively communicated with one end of the filter and the first liquid outlet 1122, and the other end of the first solenoid valve 303 is communicated with the outside; one end of the second solenoid valve 304 is communicated with the first cleaning area 111, and the other end of the second solenoid valve 304 is communicated with the other end of the circulation pump 301.

[0053] In this embodiment, the first solenoid valve 303 can ensure that when the hydrocarbon solvent in the first cleaning area 111 is insufficient, the hydrocarbon solvent can be transported to the first cleaning area 111 through the first solenoid valve 303 and the circulation pump 301. At the same time, when the hydrocarbon solvent in the cleaning tank 110 is excessive, the circulation pump 301 and the second solenoid valve 304 can be closed, and the first solenoid valve 303 can be opened to ensure that the hydrocarbon solvent in the cleaning tank 110 can be discharged in time.

[0054] In some embodiments, as Figure 2 shown, the second cleaning area 112 is further provided with a second liquid outlet 1121, the second liquid outlet 1121 is communicated with the recovery system 400, and the second liquid outlet 1121 is located above the top of the separator 120.

[0055] In this embodiment, the second liquid outlet 1121 is arranged above the top of the separator 120, which can distill and purify the hydrocarbon solvent in the second cleaning area 112 in time after the hydrocarbon solvent in the second cleaning area 112 reaches saturation.

[0056] At the same time, the second liquid outlet 1121 can also be arranged below the top of the separator 120, but it needs to be arranged above the bottom of the second cleaning area 112, and its setting position can be selected according to actual applications, and the present application does not make specific limitations.

[0057] In some embodiments, the present application further provides a connector, which is cleaned by using the connector cleaning system provided by the present application. The connector is assembled by using hardware components and plastic components, or is injection molded by using hardware components and plastic particles.

[0058] In this embodiment, during the manufacturing process of the hardware components, they can be made into conductive terminals or metal housings, and can be processed through processes such as stamping, turning and milling machining, die casting, or forging to obtain the required hardware components. After the hardware components are manufactured, electroplating can be performed on the surface of the hardware components. Specifically, surface treatment processes such as nickel plating, gold plating, silver plating, tin plating, or passivation can be carried out on the surface of the hardware components to meet the requirements for the surface treatment of the required hardware components. After that, the injection-molded plastic components can be assembled with the hardware components, or the hardware components and plastic particles can be melted together and then injected into the required molds to obtain an integrally formed connector.

[0059] Among them, after the connector is dried under vacuum negative pressure, a cleanliness detection device can be used to detect the cleanliness. After the cleanliness of the connector is detected by using the cleanliness detection device in this application, based on the number of particles per 1000 square centimeters, the number of metal particles with a size greater than 200 microns on the connector can be zero, the number of metal particles with a size not less than 150 and not greater than 200 microns can be between 0 and 8, the number of metal particles with a size not less than 100 and less than 150 microns can be between 8 and 32, and the number of metal particles with a size not less than 50 and less than 100 microns can be between 32 and 130; at the same time, the number of non-metal particles with a size greater than 600 microns on the connector can be zero, the number of non-metal particles with a size not less than 400 and less than 600 microns can be between 0 and 32, the number of non-metal particles with a size not less than 200 and less than 400 microns can be between 32 and 64, the number of metal particles with a size not less than 150 and not greater than 200 microns can be between 64 and 130, the number of metal particles with a size not less than 100 and less than 150 microns can be between 130 and 250, and the number of metal particles with a size not less than 50 and less than 100 microns can be between 250 and 500.

[0060] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed by this application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of this application.
