Description

Technical Field

[0001] This utility model relates to the field of electrical components technology, and in particular to an electrical connector. Background Technology

[0002] Compressors and refrigerant pumps are commonly used in refrigeration equipment, where the operating environment is relatively humid. This humidity can cause components to rust and can also lead to condensation seeping into the terminals, reducing insulation resistance and causing electrical leakage. This is especially true for inverter compressors, whose delicate circuit boards are more easily damaged in humid environments. Therefore, compressors and refrigerant pumps typically use waterproof junction boxes to connect to external power sources. These waterproof junction boxes are waterproof and moisture-proof, placing the wiring points inside a waterproof junction box that meets environmental protection standards. As shown in patent publication number CN 216649148 U, however, this type of junction box has a relatively complex structure, and the installation and disassembly process is cumbersome and inconvenient to use.

[0040] The electrical connector of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be used interchangeably where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0045] according to Figures 1-7 This utility model discloses an electrical connector, including a plug 2 and a fixing component 3. The plug 2 is fixedly connected to an electrical device 4 via the fixing component 3, enabling the plug 2 to be electrically connected to the electrical device 4 and supplying power to the device 4. To disassemble the electrical connector, simply remove the fixing component 3 and unplug the plug 2. To install, first connect the plug 2 to the electrical device 4, then install the fixing component 3 to fix the plug 2 to the electrical device 4. The electrical connector disclosed in this utility model has a simple structure and is easy to install and disassemble, solving the problems of complex junction box structures, cumbersome installation and disassembly processes, and inconvenience in use in existing technologies. The electrical device 4 refers to equipment such as compressors or refrigerant pumps where the wiring connections require sealing.

[0046] To facilitate the fixing of the plug 2, the fixing assembly 3 includes a lower fixing piece 31 and an upper fixing piece 32. The lower fixing piece 31 is fixedly connected to the surface of the electrical device 4, and the upper fixing piece 32 is fixedly connected to the lower fixing piece 31. One end of the upper fixing piece 32 presses against the plug 2, such as... Figure 2 As shown. In this way, the plug 2 is pressed firmly onto the surface of the electrical device 4 by the upper fixing plate 32. When disassembling, only the upper fixing plate 32 needs to be removed to remove the plug 2 as a whole.

[0047] Since multiple fixing points are required to reliably secure the plug 2 to the surface of the electrical equipment 4, to facilitate the fixing of multiple lower fixing pieces 31 to the surface of the electrical equipment 4, each lower fixing piece 31 includes a fixing ring 311 and a fixing piece body 312. The fixing ring 311 is fixed to the surface of the electrical equipment 4 by welding. The fixing piece body 312 is fixedly connected to the fixing ring 311, and the upper fixing piece 32 is fixedly connected to the fixing piece body 312. Thus, even when there are multiple fixing piece bodies 312, only the fixing rings 311 need to be fixed to the electrical equipment.

[0048] In order to securely fix the plug 2 to the surface of the electrical equipment 4, the number of fixing plate body 312 and upper fixing plate 32 are both 3 or 4.

[0049] In order to facilitate the upper fixing plate 32 to press the plug 2, the lower edge of the plug 2 is provided with a pressing step 21, and one end of the upper fixing plate 32 is pressed against the upper surface of the pressing step 21.

[0050] To facilitate the electrical connection between plug 2 and electrical equipment 4, the electrical connector also includes: socket 1, which includes mounting plate 11 and output terminal 12. Mounting plate 11 is fixedly connected to the housing of electrical equipment 4, and output terminal 12 is fixedly connected to mounting plate 11. One end of output terminal 12 is electrically connected to electrical equipment 4, and the other end extends out of the housing of electrical equipment 4. Plug 2 is electrically connected to socket 1. Plug 2 is provided with a socket, and output terminal 12 is inserted into the socket of plug 2.

[0051] The plug 2 includes a plug housing 24 and a conductive ring 25. The conductive ring 25 is fixedly connected inside the plug housing 24 and is electrically connected to the power cord 5. The inside of the conductive ring 25 is a cavity, i.e., a socket. When the plug 2 is connected to the socket 1, the output terminal 12 is inserted into the socket, i.e., the output terminal 12 is inserted into the cavity of the conductive ring 25, so that the output terminal 12 and the conductive ring 25 are electrically connected. The power cord 5 contains a U-phase wire, a V-phase wire, a W-phase wire, and a ground wire 51. The U-phase, V-phase, and W-phase wires are connected to the electrical equipment 4 through the plug 2 and the socket 1. The ground wire 51 can be connected to the housing of the electrical equipment 4 through the plug 2 and the socket 1. The ground wire 51 can also be fixed to the fixing component 3 with a fastener 33, and the fixing component 3 connects the ground wire 51 to the housing of the electrical equipment 4.

[0052] To ensure the airtightness between the plug 2 and the electrical device 4, the plug 2 also includes a sealing gasket 22, which is pressed between the plug 2 and the electrical device 4 to prevent outside air from entering the electrical connector.

[0053] To facilitate plugging and unplugging, plug 2 is provided with grooves 23, and there are two grooves 23. They are symmetrically arranged on both sides of the outer surface of plug 2 relative to the length of power cord 5. The grooves 23 are for easy plugging and unplugging by squeezing plug 2 with your hand.

[0054] To ensure the upper fixing plate 32 can better press the plug 2, the upper fixing plate 32 includes a fixing part 323 and a bending part 324, which are fixedly connected. The fixing part 323 is fixedly connected to the lower fixing plate 31, and the bending part 324 presses the plug 2. The angle between the fixing part 323 and the bending part 324 is 140°-170°, so that the bending part can undergo elastic deformation when pressed, thus better pressing the plug 2.

[0055] To facilitate the fixed connection between the upper fixing piece 32 and the lower fixing piece 31, the fixing part 323 is provided with a through hole 322, and the fastener 33 passes through the through hole 322 to fix the upper fixing piece 32 and the lower fixing piece 31.

[0056] To prevent the upper fixing piece 32 from rotating around the fastener 33, thus preventing the upper fixing piece 32 from reliably securing the plug 2, stops 321 are provided on both sides of the lower end of the fixing part 323, and the distance between the two stops 321 is greater than the width of the lower fixing piece 31. Thus, as... Figure 3 As shown, the lower fixing piece 21 is located between the two positions 321, preventing the upper fixing block from rotating relative to the fastener 33, thus ensuring that the upper fixing piece 32 reliably fixes the plug 2.

[0057] During installation, first insert the plug 2 into the socket 1, then place the upper fixing piece 32 above the lower fixing piece 31 so that the fixing part 323 is above the plug 2, and then use the fastener 33 to fix the upper fixing piece 32 and the lower fixing piece 31 together. The ground wire 51 is fixed with the fastener 33.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
