Therefore, the embodiment of the application provides a connector assembly and an electrical appliance, which can solve the technical problem that the existing easy-to-plug connector is complex in structure at least to a certain extent.

The application is described below with reference to specific embodiments in conjunction with the following drawings:

example 1:

the embodiment of the present application provides a connector assembly 100, where the connector assembly 100 may be specifically applied to an electrical appliance such as an electric kettle that needs to be frequently plugged and unplugged when in use, and the connector assembly 100 is disposed below a main unit of the electrical appliance when in use, and presses a coupling position between a connector 110 and the main unit of the electrical appliance by means of gravity of the electrical appliance, so that the electrical appliance can be electrically conducted with an external power source through the connector assembly 100 to supply power to the electrical appliance. When the host computer of electrical apparatus needs to be taken, directly with the host computer rebound can, need not fix the host computer on one hand, pull out the plug connector 110 on one hand, but one-hand operation convenient to use.

Referring to fig. 3 to 6, an overall structure and a sectional view of the connector assembly 100 are shown. Specifically, the connector assembly 100 provided in the embodiment of the present application includes a connector 110, a power line 120, and a sealing portion 130, where the connector 110 includes an electrical terminal 111 and an insulating shell 112, the electrical terminal 111 is fixed by the insulating shell 112, and the insulating shell 112 insulates between the electrical terminals 111 of different phases. The insulating shell 112 is wrapped outside the electrical terminal 111, and the insulating shell 112 is a solid of revolution, and may be a single-layer cylindrical sleeve or a multi-layer cylindrical sleeve. When the connector assembly 100 is placed on a horizontal plane, the insulating housing 112 and the electrical terminals 111 form a receptacle 113 with an upward facing opening, facilitating placement of the electrical host. The electrical terminal 111 of the connector 110 is electrically connected to the power line 120, and the sealing portion 130 covers the electrical connection portion, so that the electrical connection portion is not exposed, thereby preventing electric shock hazard, and achieving the effects of water resistance, dust resistance, and collision resistance. Therefore, compare in present insulating pot base, the connector assembly 100 that this application provided has cancelled parts such as base upper cover, base lower cover, connecting screw, very big reduction the complexity of product for product cost reduces. For example, when the connector 110 is used with an existing electric kettle connector 110, the connector assembly 100 of the present embodiment reduces the cost per unit by at least 0.6 dollars compared to the prior art water heater base shown in fig. 1 and 2.

The number of the electrical terminals 111 of the connector 110 is more than two, the electrical terminal 111 of each phase is electrically connected to a different conductive wire 121 in the power line 120, specifically, the electrical connection can be achieved by welding, riveting, screwing, winding conductors around each other, and the like, in this embodiment, the electrical terminal 111 is electrically connected to the power line 120 by welding or riveting, so as to improve the stability of the electrical connection. In certain embodiments, electrical terminals 111 of connector 110 include a positive terminal and a negative terminal. In other embodiments, referring to fig. 3, the electric terminal 111 includes a positive terminal, a negative terminal and a ground terminal that are concentrically arranged, so as to improve the electric safety and meet the electric demand of the electric appliance with the working current below 10A. The electrical terminals 111 of the connector 110 are not coaxial with the power cord 120 and are angled such that the connector 110 is perpendicular to the power cord 120 and the power cord 120 extends horizontally outward to facilitate placement of the entire connector assembly 100 on a table/counter. In other embodiments, the power line 120 may also be configured in a structure with an adjustable line outgoing angle.

In order to meet the requirement that the electrical host and the connector 110 can rotate relatively, in some embodiments, each phase electrical terminal 111 adopts a revolving structure, for example, the negative terminal, the positive terminal and the ground terminal are sequentially arranged from inside to outside along the radial direction, the ground terminal can be arranged as a cylinder or a ring, and the positive terminal and the negative terminal are both rings, which are sequentially and concentrically sleeved outside the ground terminal. In other embodiments, at least one of the positive terminal, the ground terminal and the negative terminal may be configured as a non-rotator, and in this case, only the corresponding terminal of the adapted coupler needs to be configured as a rotator, as shown in fig. 10, the coupler includes three concentrically-arranged rotator terminals, and the functions of electrically connecting the host to the connector 110 and rotating 360 ° can also be realized. Specifically, referring to fig. 6, the positive terminal 111a, the ground terminal 111c, and the negative terminal 111b are all non-rotational bodies, the patch port 113 of the connector 110 has three concentric circular grooves, and the positive terminal 111a, the ground terminal 111c, and the negative terminal 111b are respectively located in the three concentric circular grooves.

The insulating housing 112 of the connector 110 is usually made of plastic material, and can be directly injection-molded in a mold after the position of each phase electrical terminal 111 is fixed, so as to obtain the insulating housing 112 tightly fixed with each phase electrical terminal 111. In order to satisfy the requirement that the main body of the electrical appliance and the connector 110 can rotate relatively, in some embodiments, the insulating housing 112 has a rotator structure, and in particular, coupling grooves 1131 are formed in the insulating housing in the same number as the number of the electrical terminals 111; in other embodiments, the insulating housing 112 may be designed as a cylindrical structure, and the cylindrical structure is sleeved outside the electric terminals 111 of each phase in a rotational body. Other implementations of the connector 110 are not exhaustive herein.

The connector assembly 100 provided by the embodiment of the present application has a smaller overall volume than that of an existing electric kettle base (the diameter of the existing electric kettle base is usually 100-200 mm) because no outer shell is provided, and in order to stably place on a desktop/table, in some embodiments, the insulating shell 112 is circumferentially provided with a supporting portion 140, see fig. 8, and the horizontal dimension D of the supporting portion is 40-150 mm, such as 50mm, 60mm, 80mm, 100mm, 130mm, 145mm, and the like. If the support portion is a disc-shaped structure, the horizontal dimension is the diameter of the disc-shaped structure; when the supporting part is triangular, the horizontal size is the length and height of the bottom side of the triangle; if the support portion is of another shape, the length and width of the shape are both horizontal dimensions. The height H of the connector assembly 100 provided in the embodiment of the present application is 25 to 50mm, that is, the vertical distance from the top surface of the connector 110 to the bottom surface of the supporting portion 140 is 25 to 50mm, for example, 28mm, 30mm, 35mm, 38mm, 42mm, 48mm, etc. The outer dimension of the connector assembly 100 provided in the embodiment of the present application is adaptively changed according to the application object, for example, the connector assembly 100 is applied to an electric kettle, the horizontal dimension D of the support portion may be set to 40 to 100mm, and if applied to an electric rice cooker, the horizontal dimension D of the support portion may be set to 80 to 150mm.

The supporting portion 140 is a three-dimensional structure and can form a downward accommodating space 141, and the sealing portion 130 and a part of the conductive wires 121a of the power cord 120 can be placed in the accommodating space 141, so that the supporting portion 140 can increase the contact area between the entire connector assembly 100 and a table top/table top, so that the connector assembly 100 can be stably placed on the table top/table top, thereby stably supporting an electrical appliance above. And the supporting part 140 can provide protection to the sealing part 130, a part of the conductive wires 121a of the power supply line 120, which are located in the receiving space 141 thereof.

The supporting portion 140 can be set as a supporting structure or a cover body in any shape as required, in some embodiments, the supporting portion 140 is a cover body, specifically, a circular cover body, the cover body can shield the structure below the cover body, and the cover body and the table top/table top enclose a closed cavity, so that the dust-proof and collision-proof effects can be achieved on the sealing portion 130 and the part of the wires 121a of the power line 120, which are located in the cover. In order to ensure that the cover body is fully contacted with the table top/table top, the cover body is provided with a wire hole 142 for the lead 121 to pass through, and the lower edge of the cover body is not higher than the lowest point of the lead 121, specifically, the bottom surface of the cover body is not higher than the lowest point of the part of the lead 121a positioned in the cover body, so that the cover body is not lifted by the lead 121 when being placed on the table top/table top.

In order to stably support the main machine of the electric appliance, in some embodiments, the upper surface of the cover body is a plane and has a larger contact area with the main machine, and the connection between the side surface of the cover body and the upper surface adopts an inclined plane or an arc transition and can play a certain guiding role. If the bottom surface of the main frame is provided with a position-limiting clamp or a convex clamp, the surface of the cover body needs to be changed adaptively. The specific shape is not limiting of the present application.

In some embodiments, the insulating shell 112 and the supporting portion 140 are non-detachably connected, for example, when the insulating shell 112 and the supporting portion 140 are made of plastic, the insulating shell 112 and the supporting portion 140 may be integrally formed by injection molding in a mold, or integrally welded by ultrasonic welding, thermal welding, or other welding methods; when the insulating case 112 and the supporting portion 140 are made of ceramics, the insulating case 112 and the supporting portion 140 may be directly fired or fixed by gluing. The sealing portion 130 is also not detachable when in close contact with the electrical connection, in some embodiments, the sealing portion 130 is a sealant applied by an encapsulation process or a potting process, and in another embodiment, the sealing portion 130 is a molded insulating sleeve wrapped around the electrical connection between the electrical terminal 111 and the power line 120. Thus, the connector assembly 100 forms an integrated universal part, and damage caused by repeated disassembly can be avoided.

In some embodiments, the sealing portion 130 is encapsulated by a sealant, the supporting portion 140 is provided with a glue storage cavity 143, the glue storage cavity 143 is located in the accommodating space 141, and the position of the glue storage cavity 143 corresponding to the position of the electrical connection of the conductive wire, when the sealant is encapsulated, glue is injected into the glue storage cavity 143, and the glue can flow to completely wrap the connection between the electrical terminal 111 and the power line 120 under the action of gravity and fill the gap therebetween. The glue storage cavity 143 can prevent glue from flowing outwards during glue filling, and the use amount of the glue is reduced. The glue storage cavity 143 may be configured as a cylindrical sleeve, a conical sleeve, a spherical/hemispherical sleeve, a quadrilateral sleeve, or other polygonal sleeve structures, and the specific shape is not limited in this application.

The connector assembly 100 provided by the embodiment of the application has the advantages that the whole size is small and the weight is light due to the fact that the shell used for packaging is not arranged, and the connector assembly is easy to turn over when being placed on a desktop. Referring to fig. 7, in some embodiments, the connector assembly 100 further includes a suction portion 150, and the suction portion 150 may specifically adopt a fixed suction cup, and the specific structural form and number of the suction cups are not limited in this application. The suction part 150 is disposed on the bottom surface of the sealing part 130 and/or the insulating case 112, preferably below the center of gravity of the connector assembly 100, such as the bottom surface of the sealing part 130. In other embodiments, it is also contemplated to provide suction cups on the bottom surface of the insulating case 112 or the bottom surface of the supporting portion 140. The connector assembly 100 is fixed on the table top/table top by the absorption part 150, thereby preventing the connector assembly 100 from turning due to small volume and light weight. In other embodiments, a friction part, such as a rubber pad with a saw-tooth structure, capable of increasing friction force, may be disposed on the bottom surface of the connector assembly 100.

Considering that the connector assembly 100 provided by the embodiment of the present application has a small overall volume, generally smaller than the size of the bottom surface of the electrical host, it is difficult to align the coupler of the host with the connector 110 at a time when the host is placed. To improve this, referring to fig. 8, in some embodiments, the connector assembly 100 is provided with a positioning portion 160, the positioning portion 160 is provided on the supporting portion 140 and/or the sealing portion 130, the positioning portion 160 extends outward, and the extension length of the positioning portion 160 can be designed according to the size of the bottom surface of the appliance to which the connector assembly 100 is adapted, so that a user can use the positioning portion 160 as a positioning reference when placing a host computer, so that the coupler of the host computer is aligned with the connector 110. In other embodiments, it is also contemplated that the outer peripheral surface of the insulating housing 112 may be tapered to form a guide function by the tapered surface, so that the coupler of the host can be smoothly coupled with the connector 110 even if the coupler of the host is not perfectly aligned with the connector 110.

Specifically, in order to improve the versatility of the connector assembly 100, in some embodiments, the positioning portion 160 is provided as a slidable structure, and specifically, the positioning portion 160 is slidably engaged with the portion (the supporting portion 140 and/or the sealing portion 130) engaged therewith. For example, the positioning part 160 is mounted on the supporting part 140 and slidably connected with the supporting part 140, and the slidable connection can be realized in a manner that a guide rod is in clearance fit with a through hole; for example, the positioning portion 160 is configured as a slide rail, and the sealing portion 130 is configured with a matching slide block. The particular form of sliding is not limiting of the present application. By arranging the positioning portion 160 to be a slidable structure, the extending length of the positioning portion 160 can be adjusted, so that the connector assembly is suitable for electric appliances with different sizes, and a user can conveniently and quickly position the socket 113 of the connector assembly 100. Referring to fig. 8, in some embodiments, the protruding length L of the positioning portion 160 is 60mm to 200mm, such as 60mm, 80mm, 100mm, 130mm, 160mm, 170mm, 180mm, 190mm, and the like. That is, the distance between the end of the positioning part 160 far from the connector 110 and the central axis of the connector 110 can be adjusted within the range of 60-200 mm, so that the positioning requirement of the electric appliance with the diameter of less than 200mm can be met, and most of common small electric appliances in the market at present can be covered. The protruding length L of the positioning portion 160 in the connector assembly 100 provided in the embodiment of the present application is adaptively changed according to the application object, for example, when the connector assembly 100 is applied to an electric kettle, the protruding length L of the positioning portion 160 may be set to 60-120 mm, and if the connector assembly is applied to a garment steamer, the protruding length L of the positioning portion 160 may be set to 100-200 mm.

To facilitate the positioning of the positioning part 160, the positioning part 160 is slidably mounted on the supporting part 140. Referring to fig. 8, the positioning portion 160 includes a positioning rod 161 and two stoppers 162 connected to each other, and the positioning rod 161 and the stoppers 162 may be integrally formed or fixedly connected by welding or bonding. The positioning rod 161 is slidably engaged with the supporting portion 140, specifically, a through hole is formed in the supporting portion 140, the positioning rod 161 is in clearance fit with the through hole, and the positioning rod 161 is used for indicating the position of the socket 113 of the connector assembly 100. The two stoppers 162 are respectively located at two ends of the positioning rod 161, one stopper 162 is located inside the accommodating space 141 of the supporting portion 140, the other stopper 162 is located outside the supporting portion 140, the two stoppers 162 are larger than the through hole, that is, the two stoppers 162 cannot pass through the through hole, and the positioning rod 161 can be prevented from sliding off the supporting portion 140. The stopper 162 located at the outer side can also be used as a handle position, so that the positioning rod 161 can be conveniently pulled out or retracted.

Since the positioning portion 160 is slidably engaged with the supporting portion 140, it can be received in the supporting portion 140 when not in use. In order to prevent the positioning portion 160 from being completely received in the support portion 140 due to its too small volume, the gap between the side wall of the support portion 140 and the sealing portion 130 should be set to be not less than the sliding length of the positioning portion 160. In some embodiments, a through groove may be formed on a side of the sealing portion 130 close to the positioning portion 160, so that the stopper 162 and a part of the positioning rod 161 can be accommodated when the positioning portion 160 is received.

When the electric kettle is used, the extending length of the positioning rod 161 is adjusted according to the radius of the bottom surface of the electric appliance main machine, for example, a common 160mm electric kettle in the market is taken as an example, the radius of the bottom surface of the kettle is 80mm, the positioning rod 161 is correspondingly pulled outwards to a position where the outer side stop block 162 is 80mm away from the center of the connector, the outer wall of the kettle faces the outer side stop block 162 and is placed downwards, and then the kettle can be accurately placed on the connector assembly 100.
