[0054] Switches are common electrical products in people's daily lives.
[0055] The switch generally includes a control panel, a switch box and a wall-mounted dark box. In the related art, a switch box matching the specifications of the wall-mounted dark box needs to be used in conjunction.
[0056] However, the specifications of the wall-mounted boxes are various, resulting in poor versatility of the switch box body.
[0057] The present application provides a switch box body, Figure 1 FIG. 1 is a schematic diagram of the structure of a switch box in an embodiment. Figure 1 As shown, the switch box body 100 includes: a bottom box body 110 , a circuit board 120 and a box body cover 130 .
[0058] The bottom box body 110 includes a groove area 111 , and the box cover 130 is located on the concave side of the bottom box body 110 to form a cavity with the groove area 111 ; the circuit board 120 is located in the cavity.
[0059] The cross section of the groove area 111 is a polygon with four corners cut off from a rectangle; the size of the groove area 111 matches the size of the wall-mounted dark box.
[0060] The switch box body 100, the wall-mounted dark box and the control panel are components of the switch. One side of the switch box body 100 is used in conjunction with the wall-mounted dark box, and the other side is connected to the control panel.
[0061] Next, each part of the switch box 100 is described in detail.
[0062] The bottom box body 110 is the main structure of the switch box body 100 and is used to carry the circuit board 120 and the box cover 130. Figure 1 As shown, the bottom box body 110 includes a groove area 111. The open end of the groove area 111 is the concave side of the bottom box body 110, and the closed end of the groove area 111 is the convex side of the bottom box body 110. The concave side and the box cover 130 form a cavity to accommodate and protect the circuit board 120, and the convex side cooperates with the wall-mounted dark box to encapsulate the groove area 111 in the wall-mounted dark box.
[0063] Optionally, the bottom box body 110 may be made of a lightweight material. For example, the bottom box body 110 may be made of plastic, such as polypropylene oxide (PPO), polyoxymethylene (POM), etc. Figure 1 As shown, the shape of the bottom box body 110 can be a rectangle, such as a square. In the embodiment of the present application, there is no specific restriction on the material and shape of the bottom box body 110, as long as it meets the design standards and requirements.
[0064] The circuit board 120 is used to realize the transmission of control signals. Figure 1 As shown, the circuit board 120 includes a substrate 123 and a first terminal 124 and a second terminal 125. The first terminal 124 and the second terminal 125 are respectively located on both sides of the substrate 123. The first terminal 124 corresponds to the position of the reserved hole on the groove area 111. After the circuit board 120 is placed in the groove area 111, the first terminal 124 can connect the circuit board 120 with the external circuit through the reserved hole; the second terminal 125 corresponds to the position of the groove opening on the box cover 130. After the box cover 130 is assembled with the bottom box body 110, the second terminal 125 can pass through the groove opening on the box cover 130 to connect with the control panel.
[0065] Exemplarily, the circuit board 120 may be a printed circuit board (PCB). The shape and size of the circuit board 120 match the shape and size of the recessed area 111 , so that the circuit board 120 may be located in the recessed area 111 .
[0066] The box cover 130 is attached to the concave side of the bottom box body 110, and forms a cavity with the groove area 111 to accommodate the circuit board 120. Exemplarily, the box cover 130 can be connected to the bottom box body 110 by hinged connection, or can be buckled to the open end of the groove area 111 by buckling.
[0067] Optionally, the material of the box cover 130 can be the same as that of the bottom box body 110. The shape and size of the box cover 130 can match the shape and size of the bottom box body 110 so as to be aligned and fit with the bottom box body 110 to form a cavity. Figure 1 As shown, the shape and size of the box cover 130 can also match the shape and size of the groove area 111 so as to form a cavity with the box cover 130 embedded in the open end of the groove area 111.
[0068] The cross section of the groove area 111 is a polygon with four corners cut off from the rectangle. Figure 2 FIG. 1 is a schematic diagram of the outline of the groove area in one embodiment. Figure 2 As shown, the cross section of the groove area 111 can be an octagon formed by cutting each of the four corners in the positive direction. On this basis, the vertices of the octagon can be further cut to form a polygon with more sides. When the number of cuts is sufficient, the vertex of the obtained polygon can be rounded in an arc shape, and the entire polygon can also tend to be round.
[0069] Figure 3 FIG. 1 is a schematic diagram of the structure of a switch box and a wall-mounted dark box in one embodiment. Figure 3 As shown, the wall-mounted dark box H needs to be fitted with the convex side of the switch box body 100 to encapsulate the groove area 111 in the box body of the wall-mounted dark box H. Exemplarily, the size of the groove area 111 matches the size of the wall-mounted dark box H, and the maximum outer diameter of the groove area 111 can be less than or equal to the inner diameter of the wall-mounted dark box H.
[0070] It should be noted that the switch box 100 and the wall-mounted dark box of the switch need to be used together, and usually a wall-mounted dark box matching the specifications of the switch box 100 is used to match the switch box 100. This one-to-one matching method limits the application of the switch box 100, so that the switch box 100 is only applicable to the wall-mounted dark box matched with it, thereby reducing the versatility of the switch box 100.
[0071] In actual applications, the wall-mounted dark boxes include two types: circular (circular cross-section, such as European standards) wall-mounted dark boxes and square (square cross-section, such as national standards). In the above embodiment, the groove area 111 in the bottom box body 110 is a polygon with four corners cut off from the rectangle, and the size matches the wall-mounted dark box. In this way, whether a circular wall-mounted dark box or a square wall-mounted dark box is used, after the switch box body 100 is assembled with the wall-mounted dark box, the wall-mounted dark box can be matched with the groove area 111, and the groove area 111 is encapsulated in the box body of the wall-mounted dark box, so that the switch box body 100 is suitable for both types of wall-mounted dark boxes, thereby improving the versatility of the switch box body 100.
[0072] In the embodiment of the present application, the switch box provided includes a bottom box body, a circuit board, and a box cover; the bottom box body includes a groove area, the box cover is located on the concave side of the bottom box body, and forms a cavity with the groove area, and the circuit board is located in the cavity; the cross section of the groove area is a rectangular polygon with four corners cut off; the size of the groove area matches the size of the wall-mounted dark box. In the above switch box, the cross section of the groove area is a rectangular polygon with four corners cut off, and the size matches the size of the wall-mounted dark box, so that the switch box can be applied to both round and square wall-mounted dark boxes, thereby improving the versatility of the switch box.
[0073] In one embodiment, the recessed area 111 includes at least one rounded corner.
[0074] The rounded corner is an arc-shaped corner. For each vertex of the polygon formed by cutting off the four corners of the rectangle, the vertex is further cut to be a rounded corner. The rounded corner can improve the fit between the outer wall of the groove area 111 and the inner wall of the circular wall-mounted dark box.
[0075] Figure 4 FIG. 1 is a schematic diagram of the outline of the groove area in another embodiment. Figure 4 As shown, the groove area 111 may include four rounded corners, so that the cross section of the groove area 111 is a rectangle with four rounded corners. The groove area 111 including four rounded corners can make the wall-mounted dark box and the switch box body 100 fit tightly, thereby improving the sealing of the overall structure after the wall-mounted dark box and the switch box body 100 are combined.
[0076] In the embodiment of the present application, in the switch box body provided, the groove area includes at least one rounded corner. In the above switch box body, the rounded corner can improve the adaptability between the outer wall of the groove area and the inner wall of the circular wall-mounted dark box, thereby improving the fitting effect between the wall-mounted dark box and the switch box body, and correspondingly improving the sealing of the overall structure after the combination.
[0077] In one embodiment, at least one fillet is located between adjacent non-connection sidewalls in the recess region 111 .
[0078] Among them, the wiring side walls in the groove area 111 are the side walls in the groove area 111 used to realize the connection between the external circuit and the circuit board 120 located inside the groove area 111; the non-wiring side walls in the groove area 111 are the side walls in the groove area 111 that are not used to realize the connection between the external circuit and the circuit board 120.
[0079] Figure 5 FIG. 1 is a schematic diagram of the structure of the bottom box body in one embodiment, specifically a schematic diagram of the structure of the bottom box body at the opening end. For example, Figure 5 As shown, the groove area 111 in the bottom box body 110 includes four side walls a, b, c, and d, wherein side wall a is a side wall in the groove area 111 for realizing the connection between the external circuit and the circuit board 120, and side wall a is a wiring side wall, and side walls b, c, and d are non-wiring side walls in the groove area 111, and side walls b and c are adjacent, and side walls c and d are adjacent. At least one fillet included in the above-mentioned groove area 111 can be located between side walls b and c, and / or between side walls c and d. Figure 5 It is exemplarily shown in FIG. 1 that the groove area 111 includes two rounded corners, which are respectively located between the side walls b and c, and between the side walls c and d.
[0080] For the groove area 111, under the same minimum inner diameter, the available area on the rounded sidewalls in the groove area 111 is smaller than the available area on the non-rounded sidewalls. Therefore, setting the rounded corners between adjacent non-connection sidewalls in the groove area 111 can provide sufficient available area for the connection sidewalls.
[0081] In the embodiment of the present application, in the switch box provided, at least one rounded corner is located between adjacent non-wiring side walls in the groove area. In the above switch box, the rounded corners are arranged between adjacent non-wiring side walls in the groove area, which can improve the fit between the wall-mounted dark box and the switch box, while providing sufficient available area for subsequent connection with an external circuit, which can reduce the probability of wiring crosstalk and improve the application stability of the assembled switch.
[0082] To facilitate the connection and disassembly between the box cover 130 and the bottom box body 110 , in one embodiment, the switch box 100 further includes a buckle structure 140 connecting the box cover 130 and the bottom box body 110 .
[0083] The buckle structure 140 enables the box cover 130 to be detachably connected to the bottom box body 110 .
[0084] Exemplarily, the buckle interface 140 includes a buckle edge located at at least one side of the box cover 130, and the buckle edge can be flipped in a direction perpendicular to the set side, and the buckle structure 140 also includes a buckle groove located at at least one side of the bottom box body 110. After the box cover 130 and the bottom box body 110 of matching shape and size are aligned and fitted, the buckle edge on the box cover 130 is flipped toward the direction close to the bottom box body 110, so that the buckle edge on the box cover 130 and the buckle groove on the bottom box body 110 are buckled to form the buckle structure 140, so as to connect the box cover 130 and the bottom box body 110. When disassembling, the buckle edge on the box cover 130 can be flipped toward the direction away from the bottom box body 110, so that the buckle edge on the box cover 130 is separated from the buckle groove on the bottom box body 110, so as to disassemble the box cover 130 and the bottom box body 110.
[0085] To improve the compactness of the structure, in an optional embodiment, as Figure 1 As shown, the buckle structure 140 includes a buckle protrusion 141 located on the inner wall of the groove area 111 and a buckle recess 142 located on the outer wall of the box cover 130. At least one side of the circuit board 120 includes an avoidance groove 121 for the buckle protrusion 141 to pass through.
[0086] When the box cover 130 matches the shape and size of the groove area 111 in the bottom box body 110, the box cover 130 can be inserted into the open end of the groove area 111, and the buckle protrusion 141 on the inner wall of the groove area 111 is snapped into the buckle concave portion 142 on the outer wall of the box cover 130, so as to form a buckle structure 140 to connect the box cover 130 and the bottom box body 110. When disassembling, the box cover 130 can be buckled along the edge of the box cover 130, so that the buckle concave portion 142 on the outer wall of the box cover 130 is separated from the buckle protrusion 141 on the inner wall of the groove area 111, so as to disassemble the box cover 130 and the bottom box body 110.
[0087] In order to allow the buckle recess 142 on the outer wall of the box cover 130 to be buckled with the buckle protrusion 141 on the inner wall of the groove area 111, the side of the circuit board 120 needs to be designed to avoid, forming an avoidance groove 121, so that when the circuit board 120 is placed in the groove area 111 and moved, the buckle protrusion 141 on the inner wall of the groove area 111 is avoided by the avoidance groove 121, so that the buckle protrusion 141 passes through. That is, after the circuit board 120 is placed in the groove area 111, the buckle protrusion 141 is located on the outer side of the circuit board 120 (that is, the side close to the opening end of the groove area 111) to be buckled with the buckle recess 142 on the outer side of the box cover 130 embedded later.
[0088] The size of the avoidance groove 121 matches the size of the buckle protrusion 141. Exemplarily, the length of the avoidance groove 121 is greater than or equal to the length of the buckle protrusion 141.
[0089] For example, the buckle protrusion 141 in the buckle structure 140 can also be arranged on the outer wall of the box cover 130, and the buckle recess 142 can be arranged inside the groove area 111. After the box cover 130 is embedded in the groove area 111, the buckle protrusion 141 can also be snapped into the buckle recess 142 to form the buckle structure 140 connecting the box cover 130 and the bottom box body 110.
[0090] In the embodiment of the present application, the switch box provided also includes a snap-on structure for connecting the box cover and the bottom box body. The snap-on structure includes a snap-on protrusion located on the inner wall of the groove area and a snap-on concave located on the outer wall of the box cover; at least one side of the circuit board includes an avoidance groove for the snap-on protrusion to pass through. In the above switch box, a detachable connection between the box cover and the bottom box body can be achieved based on the snap-on structure, and the connection and disassembly process is simple and easy to operate. In addition, the snap-on structure can embed the box cover into the open end of the groove area without occupying additional space, thereby saving space, improving the compactness of the structure, and facilitating the miniaturization design of the overall structure.
[0091] To improve the structural stability, in one embodiment, as Figure 6 As shown, the bottom box body 110 further includes a limiting bone 112. The limiting bone 112 is located on the inner wall of the groove area 111 and extends along the depth direction of the groove area 111; at least one side of the circuit board 120 includes a limiting groove 122 for the limiting bone 112 to pass through.
[0092] The limiting bone 112 is a strip structure on the inner wall of the groove area 111, which is used to fix the position of the circuit board 120 in the groove area 111. The limiting groove 122 is a notch on the side of the circuit board 120, which matches the size, quantity and position of the limiting bone 112 on the inner wall of the groove area 111.
[0093] Exemplarily, the limiting bones 112 located on the inner wall of the groove area 111 include multiple ones, which can be arranged around the inner wall of the groove area 111. The limiting grooves 122 located on the side of the circuit board 120 include multiple ones, which are arranged around the side of the circuit board 120 corresponding to the positions of the limiting bones 112.
[0094] When placing the circuit board 120 into the groove area 111, the limiting groove 122 on the circuit board 120 can be aligned with the limiting bone 112 on the inner wall of the groove area 111, so that the limiting groove 122 can move along the extension direction of the limiting bone 112, thereby synchronously driving the circuit board 120 to move.
[0095] The limiting bone 112 guides the movement of the circuit board 120 in the depth direction of the groove area 111 and limits the movement of the circuit board 120 in other directions. The depth of the groove area 111 is usually shallow, so that the position of the circuit board 120 in the groove area 111 can be relatively stable without large deviation.
[0096] In the embodiment of the present application, in the switch box body provided, the bottom box body also includes a limiting bone; the limiting bone is located on the inner wall of the groove area and extends along the depth direction of the groove area; at least one side of the circuit board includes a limiting groove for the limiting bone to pass through. In the above switch box body, the limiting bone on the inner wall of the groove area cooperates with the limiting groove on the circuit board, so that the limiting bone can pass through the limiting groove to constrain the position of the circuit board in the groove area, and make the position of the circuit board relatively stable, thereby improving the structural stability of the overall switch box body.
[0097] When the circuit board 120 in the switch box 100 is connected to an external circuit, it will generate heat over time. In order to achieve good heat dissipation, in one embodiment, Figure 6 As shown, the bottom box body 110 further includes a heat dissipation hole 113 ; the heat dissipation hole 113 is located on at least one side wall of the groove area 111 .
[0098] Exemplarily, the side wall of the groove area 111 includes a plurality of heat dissipation holes 113. The heat dissipation holes 113 may be in the shape of a circle, a square, a triangle, or the like, or may be in the shape of a circle, a square, a triangle, or the like. Figure 6 The heat dissipation holes 113 are strip-shaped and are disposed near the closed end of the groove area 111. In the embodiment of the present application, there is no specific limitation on the shape, number and position of the heat dissipation holes 113, as long as they meet the design standards and requirements.
[0099] In the embodiment of the present application, in the switch box provided, the bottom box body further includes a heat dissipation hole; the heat dissipation hole is located on at least one side wall of the groove area. In the above switch box, the heat dissipation hole located on the side wall of the groove area can radiate the heat generated by the circuit board into the space, reduce the heat concentration on the circuit board, improve the heat dissipation effect of the switch box, and correspondingly improve the working stability and use safety of the formed switch.
[0100] To improve wiring flexibility, in one embodiment, the wiring sidewall of the groove area 111 includes a step structure 114 , and each step surface of the step structure 114 includes a reserved hole 115 .
[0101] Among them, the wiring side wall of the groove area 111 is used to realize the side wall between the external circuit and the circuit board 120 located inside the groove area 111, and the connection between the external circuit and the circuit board 120 is realized through the reserved hole 115 on the side wall of the groove area 111.
[0102] After the circuit board 120 is placed in the groove area 111, the connection post corresponds to the reserved hole 115 on the inner wall of the groove area 111, and the connection post can be connected to the external circuit through the reserved hole 115. Therefore, the side wall where the reserved hole 115 is located on the groove area 111 is the connection side wall of the groove area 111, and the non-connection side wall is the side wall of the groove area 111 where the reserved hole 115 is not set.
[0103] Figure 7 This is a schematic diagram of the structure of the bottom box body in another embodiment, specifically: Figure 5 Schematic diagram of the structure of the bottom box body at the closed end.
