Due to the existence of the wiring hole, the wiring hole and the connected wire cannot be sealed, so that the sealing performance of the wire control device is poor, so that the wire control device cannot be in a sealed state, and if the wire control device is in a humid environment for a long time, short circuit may occur, causing damage to the machine.

[0048] In order to solve the technical problems of poor sealing performance, easy to be damp and hidden danger of safety of the wire control device in the prior art, the main purpose of the present application is to provide a wire control device and an electric appliance which can effectively improve the sealing performance, are not easy to be damp and have high safety.

[0049] Reference Figure 1 and Figure 2As shown, according to one aspect of the present application, a kind of wire controller is provided, including main body 10, main plate 20, first connecting piece 30 and second connecting piece 40, main body 10 is equipped with containing cavity 11 and first aperture 12 being communicated with containing cavity 11;Main plate 20 is arranged in containing cavity 11, and main plate 20 has conductive contact 21, first connecting piece 30 is connected with main body 10 by first aperture 12, and first connecting piece 30 surrounds limit cavity 31, and limit cavity 31 has conductive partition 32 inside, and conductive contact 21 is electrically connected with one side of conductive partition 32;Second connecting piece 40 is assembled and connected with first connecting piece 30 by limit cavity 31, and one end of second connecting piece 40 is electrically connected with the side of conductive partition 32 away from conductive contact 21, and the other end of second connecting piece 40 is connected with external power supply.

[0050] As an example, main body 10 includes first shell 14 and second shell 15, and containing cavity 11 is surrounded between first shell 14 and second shell 15, first aperture 12 is opened on first shell 14 or second shell 15 in it, first aperture 12 is communicated with containing cavity 11, first connecting piece 30 extends to main plate 20 by first aperture 12, limit cavity 31 surrounded by first connecting piece 30, and conductive partition 32 in limit cavity 31 is electrically connected with conductive contact 21 on main plate 20, when power supply is needed to main plate 20, second connecting piece 40 is matched with limit cavity 31, so that first connecting piece 30 is fixedly connected with second connecting piece 40, preferably, limit cavity 31 can be sealed and wrapped in the outer periphery of second connecting piece 40, second connecting piece 40 extends to conductive partition 32 in limit cavity 31 and is electrically connected with conductive partition 32, and one end of second connecting piece 40 located outside main body 10 is connected with external power supply, then, main plate 20, conductive contact 21, conductive partition 32 and second connecting piece 40 are electrically connected, to achieve the purpose of power supply for main plate 20.

[0051] Conductive partition 32 can be arranged at one end of limit cavity 31 facing main plate 20, and then the limit cavity 31 and the second connecting piece 40 are surrounded by the conductive partition 32 to form a sealed closed cavity, thereby effectively preventing moisture from entering the limit cavity 31, and preventing moisture from entering the containing cavity 11 through the conductive partition 32.

[0052] In one embodiment of the present application, first connecting piece 30 can be plastic encapsulated in first aperture 12, so that first connecting piece 30 is sealingly connected with main body 10, further improving the sealing between first sealing member 70 and main body 10, and conductive partition 32 and first connecting piece 30 are injection molded, the first aperture 12 is completely blocked by the outer wall of the conductive partition 32 and the first connecting piece 30, further improving the sealing between the second connecting piece 40 and the first connecting piece 30, and the sealing between the first connecting piece 30 and the second connecting piece 40.

[0053] In the embodiment, the outer wall of the first connecting member 30 can be made of insulating material or conductive material to improve the flexibility of the user during use.

[0054] Referring to Figure 1 As shown, according to an embodiment of the present application, a third connecting member 50 is further included, one end of the third connecting member 50 abuts against the conductive contact 21, and the other end abuts against the conductive partition plate 32, and the first connecting member 30 is electrically connected with the third connecting member 50 and the conductive contact 21 through the conductive partition plate 32.

The third connecting member 50 serves as an electrical connecting member between the conductive contact 21 and the conductive partition plate 32. Further, the third connecting member 50 improves the stability of the electrical connection between the conductive partition plate 32 and the conductive contact 21. The third connecting member 50 can extend from the conductive partition plate 32 to the conductive contact 21, so that the third connecting member 50 is fixed between the main board 20 and the second connecting member 40.

[0055] Referring to Figure 11 As shown, preferably, one end of the third connecting member 50 is fixedly connected with the main board 20, and the other end is detachably connected with the conductive partition plate 32. The first connecting member 30 is sealingly connected with the second shell 15 through the first opening 12. The first shell 14 and the second shell 15 form the accommodating cavity 11. The first shell 14 and the second shell 15 are provided with a sealing ring 16 at the assembly position. The first shell 14 and the second shell 15 are sealingly and fixedly connected by extruding the sealing ring 16.

[0056] In combination with the above embodiment, since the power supply of the main board 20 is directly connected with the external power supply through the second connecting member 40 at the outer end of the second shell 15, when the second shell 15 is detached, the conductive partition plate 32 and one end of the third connecting member 50 are not in contact. Even if the other end of the third connecting member 50 is connected with the conductive contact 21, the main board 20 cannot be powered. Compared with the prior art, there is no need to reassemble the wire, which saves assembly time, improves assembly efficiency, and when the main board 20 needs to be powered, the conductive contact 21, the third connecting member 50 and the conductive partition plate 32 are only needed to be positioned correspondingly, and then connected, so that the external power supply can be used to charge the main board 20 through the second connecting member 40 assembled with the first connecting member 30, thereby further reducing the cost of later maintenance.

[0057] Referring to Figure 3 and Figure 4As shown, according to an embodiment of the present application, the limiting cavity 31 comprises a first assembly cavity 311 and a second assembly cavity 312 on opposite sides of the conductive partition 32, the second connecting member 40 is assembled with the first connecting member 30 through the first assembly cavity 311, and the third connecting member 50 is limited in the second assembly cavity 312, the conductive contact 21 faces the second assembly cavity 312, and the conductive contact 21, the third connecting member 50, the conductive partition 32 and the first connecting member 30 are electrically connected.

[0058] As an example, after the second connecting member 40 is assembled with the first connecting member 30 in the first assembly cavity 311, the conductive partition 32 encloses the first assembly cavity 311 into a sealed cavity, the first opening 12 is completely closed by the conductive partition 32, the second assembly cavity 312 is a sealed cavity, one end of the third connecting member 50 is limited in the second assembly cavity 312, and the relative displacement of the third connecting member 50 relative to the conductive contact 21 and the conductive partition 32 is limited by the second assembly cavity 312, so as to improve the stability of the electrical connection between the third connecting member 50 and the conductive contact 21 and the conductive partition 32, improve the stability of the power supply of the main board 20, and further improve the service life of the drive-by-wire controller.

[0059] Referring to Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, according to an embodiment of the present application, the main body 10 further comprises a boss 13, the boss 13 comprises a limiting wall 131, the limiting wall 131 encloses the first opening 12, and the first connecting member 30 and the limiting wall 131 have a clamping surface 132 (not labeled in the figure) in the assembly direction of the first connecting member 30, and the first connecting member 30 is interference fit with the main body 10 through the clamping surface 132. The limiting wall 131 surrounds the outer periphery of the first connecting member 30, further improving the strength and sealing performance of the mechanical fixation of the first connecting member 30 and the main body 10 in the assembly direction of the first connecting member 30 and the main body 10.

[0060] In an example of the present application, the main body 10 and the first connecting member 30 are detachably connected, so that the first connecting member 30 is interference fit with the main body 10 in the assembly direction, and the first connecting member 30 and the limiting wall 131 have a clamping surface 132 (not labeled in the figure), and the sealing performance between the first connecting member 30 and the main body 10 is improved through the clamping surface 132 of the concave-convex fit, and the sealing performance of the first connecting member 30 to block the first opening 12 is further improved.

[0061] Referring to Figure 2 and Figure 4As shown, according to an embodiment of the present application, the first connecting piece 30 has a necking wall 33 and two flaring walls 34 along the assembly direction of the first connecting piece 30 and the first opening 12, the necking wall 33 is located between the two flaring walls 34, the necking wall 33 and the two flaring walls 34 form a limiting cavity 31, and the conductive partition plate 32 is fixedly limited on the necking wall 33; the limiting wall 131 includes a first cavity 1311 facing the flaring wall 34 and a second cavity 1312 facing the necking wall 33, the opening diameter of the first cavity 1311 is larger than that of the second cavity 1312, the first cavity 1311 and the second cavity 1312 are communicated to form the first opening 12, the flaring wall 34 is arranged in the first cavity 1311, and the necking wall 33 is arranged in the second cavity 1312.

[0062] Further, the flaring wall 34 is matched with the first cavity 1311 to be clamped with the main body 10, the necking wall 33 further prevents the moisture from flowing from the first cavity 1311 close to the outer side of the main body 10 to the second cavity 1312, and the sealing performance of the wire controller is further improved.

[0063] According to an embodiment of the present application, the limiting wall 131 is made of insulating material to improve the safety of the wire controller in use, and the first connecting piece 30 is made of conductive material.

[0064] Reference Figure 1 , Figure 5 and Figure 6 As shown, according to an embodiment of the present application, the first connecting piece 30 further includes a blocking piece 60, the blocking piece 60 is arranged on the opening of the first opening 12, the blocking piece 60 includes a baffle 61 and a through hole 62 arranged in the middle of the baffle 61, the first connecting piece 30 includes a connecting rod 41 and a protrusion 42 arranged at one end of the connecting rod 41, the protrusion 42 abuts against the circumferential side of the baffle 61, the connecting rod 41 extends through the through hole 62 to the limiting cavity 31, so as to be connected with the second connecting piece 40 through the limiting cavity 31, and the protrusion 42, the connecting rod 41 and the conductive partition plate 32 are electrically connected. The blocking piece 60 and the protrusion 42 are matched to prevent the moisture from entering the limiting cavity 31, the baffle 61 and the protrusion 42 abut against the outer periphery of the first opening 12 to further form a sealed space between the blocking piece 60 and the first opening 12, so as to prevent the moisture from entering the accommodating cavity 11 from the first opening 12.

[0065] The connecting rod 41 can be arranged in threaded cooperation with the first connecting piece 30, and a thread matched with the outer periphery of the connecting rod 41 is arranged in the limiting cavity 31, so as to improve the sealing performance in the limiting cavity 31 after assembly.

[0066] Meanwhile, since the first connector 30 is made of conductive material, after the connecting rod 41 is threadedly connected to the limiting cavity 31, the first connector 30 and the second connector 40 can be electrically connected. Therefore, the connecting rod 41 does not need to abut against the conductive partition 32 to be electrically connected to the conductive partition 32, which effectively reduces costs. After the protrusion 42 is electrically connected to the external power supply, the second connector 40 can be connected. The protrusion 42, the connecting rod 41 and the conductive partition 32 are electrically connected, which facilitates power supply to the motherboard 20.

[0067] According to one embodiment of this application, it further includes a sealing member 70, which is disposed around the periphery of the first opening 12 between the baffle 61 and the main body 10. As an example, see [reference needed]. Figure 1 and Figure 5 As shown,

[0068] refer to Figure 5 As shown, according to one embodiment of this application, it includes a plurality of sealing members 60, which are stacked along the extending direction of the connecting rod 41. At least one pair of adjacent sealing members 60 forms a wire-fixing cavity 63. The wire of the external power supply is limited and fixed in the wire-fixing cavity 63 and electrically connected to the connecting rod 41. After the connecting rod 41 is fixed to the limiting wall 131, the wire-fixing cavity 63 between the plurality of sealing members 60 is adjusted. After the wire is fixed in the wire-fixing cavity 63, the wire can be limited and fixed in the wire-fixing cavity 63 by the thread between the connecting rod 41 and the limiting wall 131. On the basis of improving the sealing performance by using multiple sealing members 60, the stability of the electrical connection between the second connecting member 40 and the external power supply is further improved.

[0069] refer to Figure 1 , Figure 2 and Figure 11 As shown, according to one embodiment of this application, the motherboard 20 further includes a limiting platform 22, which surrounds a wiring port 221. A conductive contact 21 is located at one end of the wiring port 221. The wiring port 221 is disposed opposite to the second assembly cavity 312. The two ends of the third connector 50 are respectively limited and fixed in the wiring port 221 and the second assembly cavity 312.

[0070] In conjunction with the above embodiments, the relative position of the third connector 50 to the conductive contact 21 is further defined by the wiring port 221, thereby improving the stability of the electrical connection between the third connector 50 and the motherboard 20 through the second assembly cavity 312 and the wiring port 221.

[0071] refer to Figure 1 , Figure 8 , Figure 9 and Figure 11As shown, according to an embodiment of the present application, the third connecting piece 50 includes a first connecting column 51 and two second connecting columns 52, the second connecting columns 52 are arranged at both ends of the first connecting column 51, the first connecting column 51 includes a first abutting surface and a second abutting surface, the first abutting surface abuts against the first connecting piece 30 through the second assembly cavity 312, the second abutting surface abuts against the limiting table 22 corresponding to the wiring port 221, the diameter of the first connecting column 51 is greater than the diameter of the second connecting column 52, which reduces the cost, and the first connecting column 51 and the second connecting column 52 can respectively realize stable electrical connection with the conductive partition plate 32 and the conductive contact 21.

[0072] In addition, the first abutting surface (not labeled) and the second abutting surface (not labeled) can be stressed and abut against the inner wall of the second assembly cavity 312 and the limiting table 22 corresponding to the wiring port 221, respectively, to improve the stability of the electrical connection.

[0073] In another embodiment, referring to Figure 7 As shown, according to an embodiment of the present application, the third connecting piece 50 includes an assembly wall 53 and an elastic wall 54, the assembly wall 53 is fixedly connected with the conductive partition plate 32, one end of the elastic wall 54 is electrically connected with the assembly wall 53, and the other end elastically abuts against the conductive contact 21, so that the conductive partition plate 32 is electrically connected with the conductive contact 21. The assembly wall 53 and the conductive partition plate 32 can be arranged as an integrated structure, so that the position of the third connecting piece 50 relative to the conductive contact 21 can be fixed by the second connecting piece 40, and the stability of the electrical connection can be further improved by the elastic abutment of the elastic wall 54 against the conductive contact 21 according to the use condition.

[0074] In a specific use condition of the present application, the drive-by-wire controller includes a mainboard 20, an upper shell and a lower shell, the mainboard 20 is arranged in a containing cavity 11 formed between the upper shell and the lower shell, in order to supply power to the mainboard 20, an external power supply is needed, and a wiring hole is generally needed to be formed on the upper shell or the lower shell, a wire needs to pass through the wiring hole on the shell and be connected to the mainboard 20 through the wiring hole, so as to achieve the purpose of supplying power to the mainboard 20. Due to the existence of the wiring hole, the wiring hole and the connected wire cannot be sealed, which makes the sealing performance of the drive-by-wire controller poor, and the drive-by-wire controller cannot be in a sealed state. If the drive-by-wire controller is used in a humid environment for a long time, short circuit may occur, causing damage to the machine.

[0075] In addition, the wire is prone to displacement relative to the wiring hole, and when the drive-by-wire controller is disassembled and assembled, the position of the wire needs to be adjusted again, so as to avoid the problem of loose connection between the wire and the mainboard 20, which may cause safety hazards.

[0077] Compared with the prior art, the line control box avoids the existence of the wiring hole, fixes the connecting wire on the inlaid nut (equivalent to the first connecting piece 30) outside the bottom shell through the nut (equivalent to the second connecting piece 40), inserts a conductive terminal (equivalent to the third connecting piece 50) in the bottom shell into the inlaid nut, and inserts the conductive terminal into the terminal hole on the mainboard 20, so that strong current is conducted to the mainboard 20 through the connecting wire and the conductive terminal, and sealing is achieved.

[0078] When disassembling, only the upper shell and the bottom shell need to be disassembled according to the corresponding positions, quick disassembly is achieved, and time is saved.

[0079] Specifically, the line controller includes an upper shell and a bottom shell, a sealing ring 16 is arranged at a connection between the upper shell and the bottom shell, and the upper shell and the bottom shell are in contact and sealed by extruding the sealing ring 16.
