[0034] Figure 1 Some preferred embodiments of the controller of this utility model are shown. The controller has remote communication capabilities and offers advantages such as easy assembly, reliable signal transmission, and reliable fastening.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the controller includes a housing 10, an RF connector 20, and an insulating bracket 30; the housing 10 can be used to house a circuit board and other devices. The insulating bracket 30 may be disposed in the housing 10, which can be used to fix the RF connector 20 and isolate the RF connector 20 from the housing 10. The RF connector 20 is mounted on the insulating bracket 30 and partially protrudes from the housing 10, and is insulated from the housing 10 by the insulating bracket 30.

[0036] The housing 10 is hollow inside and may include a body 11 and a panel 12 disposed on one side of the body 11. The body 11 may be generally cuboid in shape, with an inner cavity for accommodating circuit components, such as circuit boards. An opening 111 may be provided on one side of the body 11 for assembling circuit components. In some embodiments, the panel 12 may be connected and fixed to the body 11 by a connecting component, and the connection between the two may be detachable. In some embodiments, the connecting component may be a screw assembly, a snap-fit ​​assembly, an adhesive assembly, etc. Detachably connecting the panel 12 to the body 11 facilitates the maintenance of circuit components. In other embodiments, the panel 12 and the body 11 may also be fixed by welding to form a non-detachable structure.

[0037] In some embodiments, the housing 10 may be made of metal. In some embodiments, the housing 10 as a whole may be made of sheet metal, that is, the body 11 and the panel 12 may be made of sheet metal. In other embodiments, the housing 10 may not be limited to being made entirely of sheet metal; it may also be a plastic housing 10.

[0038] In some embodiments, the housing 10 has a through hole 121, which may be provided on the panel 12. The through hole 121 may be at least one, and in some embodiments, there may be two through holes 121. Of course, it is understood that in other embodiments, the through holes 121 may not be limited to two, but may also be three, four, etc. The number of through holes 121 may be determined according to the number of RF connectors 20.

[0039] like Figure 3 and Figure 4As shown, in some embodiments, the RF connector 20 may be mounted on the insulating bracket 30 and partially protrude from the through-hole 121. Specifically, the RF connector 20 may be connected to a circuit board in the housing 10 and may partially protrude from the through-hole 121 for signal transmission. In some embodiments, the RF connector 20 may be a conventional RF connector. In some embodiments, the RF connector 20 may include a connector body 21 and a base 22, the connector body 21 being disposed protruding from the through-hole 121. In some embodiments, the connector body 21 may be generally columnar, and its outer side wall may be provided with an external thread structure 211. The base 22 is disposed at one end of the connector body 21 and may serve to limit the installation of the RF connector 20. The cross-sectional area of ​​the base 22 may be larger than the cross-sectional area of ​​the RF connector 20, and the cross-section of the base 22 may be generally non-circular, and may be polygonal, such as one of triangles, quadrilaterals, pentagons, and hexagons. By designing the cross-section of the base 22 as non-circular, it is beneficial to align the base 22 with the insulating support 30, thereby improving the assembly efficiency and stability of the assembly.

[0040] In some embodiments, the insulating bracket 30 may be disposed on the inner side of the panel 12, partially embedded in the through hole 121. Specifically, the insulating bracket 30 may be disposed on the inner surface of the panel 12. The insulating bracket 30 may be integrally formed with the panel 12. In some embodiments, the insulating bracket 30 and the panel 12 may be fixed together by welding or adhesive to form an integral structure. In other embodiments, the insulating bracket 30 may also be integrally formed with the panel 12, for example, by injection molding. By providing the insulating bracket 30, the RF connector 20 is at least partially insulated from the panel 12, and the RF connector 20 is indirectly in contact with the housing 10, thereby achieving the function of shielding signals, avoiding signal interference, and making signal transmission reliable and stable. In some embodiments, the insulating bracket 30 may be made of insulating materials, such as plastic, silicone, ceramic, etc.

[0041] In some embodiments, the insulating support 30 may include a support 30b and a protrusion 30b. The support 30b may be longitudinally arranged and may cover all the perforations 121. The support 30b may be fitted to the inner surface of the panel 12. In some embodiments, the protrusion 30b may protrude from the support 30b, and there may be at least one protrusion 30b, which may correspond one-to-one with the perforations 121. In this embodiment, there may be two protrusions 30b. Of course, it is understood that in some other embodiments, the protrusions 30b may not be limited to two. The protrusion 30b may be generally cylindrical and may be inserted into the perforation 121 to insulate the RF connector 20 from the inner sidewall of the perforation 121.

[0042] In some embodiments, the insulating support 30 has a through hole 31, which can extend from the support 30b to the protrusion 30a. The through hole 31 can be coaxially arranged with the through hole 121 and the two can be connected. By providing the through hole 31, the radio frequency connector 20 can be easily passed through the through hole 121.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments, the controller further includes a first limiting structure, which can be disposed on an insulating support. The controller also includes a second limiting structure, which can be disposed on the RF connector 20. The second limiting structure can cooperate with the first limiting structure, thereby enabling the RF connector 20 to rotate freely, making the RF connector 20 easier to install and remove, and also making its fastening more reliable.

[0044] In some embodiments, the first limiting structure may include a groove 32, which may be disposed at one end of a through hole 31. The groove 32 may be formed in a support 30b and coaxially disposed with a through hole 121, communicating with the through hole 121 through the through hole 31. The cross-section of the groove 32 may be generally non-circular. In some embodiments, the cross-section of the groove 32 may be at least one of a triangle, quadrilateral, pentagon, or hexagon. Specifically, the base 22 has a hexagonal cross-section, and the groove 32 may be a hexagon that mates with the base 22. The inner wall of the groove 32 has at least one first cut surface 321 and at least two notches 322. The at least one first cut surface 321 may form a first limiting surface, and the at least two notches 322 may form a limiting opening.

[0045] A second limiting structure may be formed on the base 22. Generally, the cross-section of the base 22 is non-circular, thus forming a second limiting structure that mates with the groove 32. The outer wall of the base 22 has at least one second cut surface 221 and at least two protruding ridges 222. The at least one second cut surface 221 may form a second limiting surface, and the at least two protruding ridges 222 may form a second limiting ridge. In some embodiments, the cross-section of the base 22 may be approximately hexagonal. The second cut surface 221 may mate with the first cut surface 321, and the protruding ridges 222 may mate with the recess 322.

[0046] In some embodiments, the controller further includes a fastening assembly 40 for fastening the connector body 21 and the housing 10, the fastening assembly 40 including a fastening nut 41. The fastening nut 41 can be sleeved on the connector body 21 and screwed to the connector body 21. The fastening nut 41 can be a conventional nut whose internal thread is adapted to the external thread structure of the connector body 21.

[0047] In some embodiments, the fastening assembly 40 further includes an insulating washer 42, which is sleeved on the connector body 21 and located between the fastening nut 41 and the housing 10. Specifically, it may be disposed on the outer surface of the panel 12, located between the panel 12 and the fastening nut 41. This insulates the RF connector 20 from the panel 12. In some embodiments, the insulating washer 42 may be an O-ring, a silicone ring, or a rubber ring. In other embodiments, the insulating washer 42 may be omitted.

[0048] In some embodiments, the fastening assembly 40 further includes an elastic washer 43, which can be fitted onto the connector body 21 and is located between the fastening nut 41 and the housing 10. Specifically, the elastic washer 43 may be generally C-shaped and may be disposed between the fastening nut 41 and the insulating washer 42 to reduce friction between the fastening nut 41 and the insulating washer 42 or the panel 12. In some embodiments, the elastic washer 43 may be a metal washer.
