Sound box terminal containing structure

Abstract

The application provides a speaker terminal containing structure for a ceiling speaker, which comprises a shell, a first boss and a plurality of terminals. The shell has a bottom wall and a peripheral wall connected to the bottom wall and extending in a first direction, and the peripheral wall has a flat portion on one side of its outer surface. The first boss is formed on the flat portion and protrudes in a second direction away from the peripheral wall, so that a stepped structure is formed between the first boss and the flat portion, the first boss forms a terminal setting area on the top opposite to the flat portion, and the second direction is perpendicular to the first direction. The plurality of terminals are arranged in the terminal setting area. The boss structure can be punched in the same direction as the shell, the tensile rate of the material can be controlled within a certain range, and the problem of tensile fracture does not occur. Since the stepped structure is formed between the boss structure and the shell, the connection between the boss structure and the shell is in the form of an arc-shaped guide groove, which can block and guide water droplets, and in addition, the boss structure protruding in the middle does not have the problem of water accumulation.

Description

Technical Field

[0001] This application relates to the technical field of loudspeaker enclosure structures, and in particular to a loudspeaker terminal receiving structure in which a boss is formed in the housing to accommodate terminals. Background Technology

[0002] Ceiling-mounted speakers typically have grooves formed on the surface of a metal casing through a stamping process to house the terminals. Since the casing is formed by stamping a sheet metal in one direction, while the groove is formed by stamping the casing in the opposite direction, the material in the groove has greater tensile strength than other parts of the casing. Therefore, the groove is prone to breakage after stamping. Another technical solution, when there are many terminal housings, involves forming a separate groove-shaped terminal box and then welding it to the casing. However, this requires the terminal box to be manufactured separately, adds a welding step, increases manufacturing costs, and can lead to various welding problems, such as reduced water resistance or weld marks affecting the appearance. Furthermore, because the existing terminal housing structure is groove-shaped, water can easily accumulate inside the groove if it flows in. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this application is to provide a speaker terminal receiving structure to solve the problems of easy breakage due to increased stretching caused by the opposite stamping direction of the shell and the groove, and the easy accumulation of water in the groove-shaped terminal receiving structure.

[0004] To achieve the above and other related objectives, this application provides a speaker terminal housing structure for a ceiling-mounted speaker, comprising a housing, a first boss, and a plurality of terminals. The housing has a bottom wall and a peripheral wall formed by extending along a first direction from the edge of the bottom wall. The peripheral wall has a flat portion on one side of its outer surface. The first boss is formed on the flat portion and protrudes in a second direction away from the peripheral wall, forming a stepped structure between the first boss and the flat portion. The first boss forms a terminal mounting area at its top opposite the flat portion, and the second direction is perpendicular to the first direction. A plurality of terminals are disposed in the terminal mounting area.

[0005] Optionally, the first boss is located in the middle of the flat portion in the third direction, and the first boss is connected to the flat portion on opposite sides in the third direction, with the third direction being perpendicular to the first direction and the second direction.

[0006] Optionally, the flat portion is adjacent to the bottom wall; the first boss is adjacent to the bottom wall.

[0007] Optionally, the first boss extends from the bottom wall parallel to the flat portion along a first direction.

[0008] Optionally, two connection points where the first boss connects to the flat portion are respectively formed with arc-shaped guide grooves, and the two arc-shaped guide grooves are parallel to each other and extend along the first direction.

[0009] Optionally, it also includes a second boss connected to the first boss and the flat portion, the second boss extending along the first direction, and the height of the second boss in the second direction being greater than the height of the first boss in the second direction.

[0010] Optionally, the connection between the second boss and the first boss is disposed opposite to the bottom wall, and the connection between the second boss and the first boss forms an inclined surface that is inclined relative to the top of the first boss, and the inclined surface is oriented away from the peripheral wall, and two arc-shaped guide grooves extend to the opposite sides of the inclined surface.

[0011] Optionally, the connection between the second boss and the flat portion forms an arc-shaped surface, and the arc-shaped surface is connected to the arc-shaped guide groove.

[0012] Optionally, the second boss is connected to the peripheral wall, and the connection between the second boss and the peripheral wall forms an arc-shaped concave surface, which is connected to the flat portion.

[0013] Optionally, it also includes a terminal cover that covers the first boss and the bevel.

[0014] Optionally, the terminal cover includes a top plate, two first side plates and a second side plate. The two first side plates are respectively connected to opposite sides of the top plate, and the second side plate is connected to one side of the top plate and adjacent to the two first side plates. The top plate is flush with the top of the second boss, and the two first side plates are combined with opposite sides of the first boss and are respectively adjacent to two arc-shaped guide grooves. The second side plate is flush with the bottom wall.

[0015] As described above, this application has the following beneficial effects:

[0016] Because the speaker terminal housing structure of this application forms a boss structure on the shell, the boss structure can be stamped in the same direction as the shell during the subsequent stamping process. This allows the material's elongation rate to be controlled within a certain range, preventing tensile breakage. Since the boss structure has no limitations on height or depth, its size can be adjusted according to the number of terminals. Regardless of size, the boss can be integrally formed with the shell without disassembly and re-welding. Because the boss structure forms a stepped structure with the shell, and the connection point is shaped like an arc-shaped guide groove, it effectively blocks and guides water droplets. Furthermore, the raised boss structure in the middle prevents water accumulation. Attached Figure Description

[0028] Please see Figure 1 , Figure 2 and Figure 3 ,in Figure 1 The diagram shown is a perspective view of a terminal receiving structure according to an embodiment of this application. Figure 2 Displayed as Figure 1 Partial exploded perspective view of the terminal housing structure. Figure 3 Displayed as Figure 1 A perspective view of the terminal housing structure with the terminal cover removed, in which... Figure 2 and Figure 3 The shape of the structure is shown in outline. As shown in the figure, the speaker terminal receiving structure 1 of this embodiment is used for a ceiling-mounted speaker. The speaker terminal receiving structure 1 of this embodiment includes a housing 10, a first boss 20, a second boss 30, a plurality of terminals 40, and a terminal cover 50.

[0029] The housing 10 has a bottom wall 11 and a peripheral wall 12 connected to the edge of the bottom wall 11 and extending along a first direction L1. The housing 10 may be formed by stamping a sheet metal along the first direction L1. The peripheral wall 23 has a flat portion 121 on one side of its outer surface. The flat portion 121 is disposed adjacent to the bottom wall 11.

[0030] A first protrusion 20 is formed on the flat portion 121 and protrudes in a second direction L2 away from the peripheral wall 12, forming a stepped structure between the first protrusion 20 and the flat portion 121. The first protrusion 20 is located in the middle of the flat portion 121 in the third direction L3. The side of the first protrusion 20 closest to the bottom wall 11 is adjacent to the bottom wall 11. The opposite sides of the first protrusion 20 in the third direction L3 are connected to the flat portion 121. Each of the two connection points between the first protrusion 20 and the flat portion 121 forms an arc-shaped guide groove 21. The two arc-shaped guide grooves 21 are parallel to each other and extend along the first direction L1. The arc-shaped guide grooves 21 are connected to the bottom wall 11. The first direction L1, the second direction L2, and the third direction L3 are perpendicular to each other.

[0031] The first boss 20 forms a terminal setting area on the top 22 opposite to the flat portion 121, and a plurality of terminals 40 are disposed in the terminal setting area.

[0032] The second boss 30 connects to the first boss 20, the flat portion 121 of the peripheral wall 12, and other portions of the peripheral wall 12 adjacent to the flat portion 121. The second boss 30 extends from one side of the first boss 20 along a first direction L1 away from the bottom wall 11, and the height of the second boss 30 in the second direction L2 is greater than the height of the first boss 20 in the second direction L2. The connection between the second boss 30 and the first boss 20 is opposite to the bottom wall 11, and the connection between the second boss 30 and the first boss 20 forms an inclined surface 31 that is inclined relative to the top 22 of the first boss 20, and the inclined surface 31 faces away from the peripheral wall 12. Two arc-shaped guide grooves 21 extend to opposite sides of the inclined surface 31, and the connection between the second boss 30 and the flat portion 121 forms an arc-shaped curved surface 32, and the arc-shaped curved surface 32 is connected to the arc-shaped guide grooves 21. The arc-shaped curved surface 32 extends from the flat portion 121 to the top 33 of the second boss 30 in an inclined manner. The top 33 of the second boss 30 is adjacent to the inclined surface 31. The top 33 is an arc-shaped curved surface and protrudes in the direction away from the peripheral wall 12 along the second direction L2. In addition, the second boss 30 is also connected to other parts of the peripheral wall 12 on the outer side of the flat portion 121, and an arc-shaped concave surface 34 is formed at the connection between the second boss 30 and the peripheral wall 12 on the outer side of the flat portion 121. The arc-shaped concave surface 34 is connected to the flat portion 121.

[0033] The terminal cover 50 covers the inclined surface 31 of the first boss 20 and the second boss 30, thereby covering a plurality of terminals 40 disposed in the terminal setting area.

[0034] The terminal cover 50 includes a top plate 51, two first side plates 52, and a second side plate 53. The two first side plates 52 are respectively connected to opposite sides of the top plate 51, and the second side plate 53 is connected to one side of the top plate 51 and adjacent to the two first side plates 52. The top plate 51 is flush with the top 33 of the second boss 30 and has an arc-shaped curved surface. The two first side plates 52 are connected to opposite sides of the first boss 20 and are respectively adjacent to two arc-shaped guide grooves 21. The second side plate 53 is flush with the bottom wall and has two extending lugs 531 that extend to the bottom wall 11. Each extending lug 531 is bolted to the bottom wall 11, so that the terminal cover 50 is fixed to the housing 10 and covers the terminal 40, thereby protecting the terminal 40.

[0035] Please see Figure 4 , Figure 4 The diagram shows water droplets flowing down from both sides of the terminal cover. When water droplets fall on the bottom wall 11 of the housing 10, the water droplets (indicated by dashed lines) can flow along the arc-shaped guide groove 21, and then through the arc-shaped curved surface 32 formed at the connection between the second boss 30 and the flat portion 121, and the arc-shaped concave surface 34 formed at the connection between the second boss 30 and the outer peripheral wall 12 of the flat portion 121, all the way to the other end of the housing 10, without causing water accumulation in the terminal setting area.

[0036] Please see Figure 5 and Figure 6 , Figure 5 Displayed as Figure 1 A top view of the speaker terminal housing structure. Figure 6 for Figure 5 A cross-sectional view along line AA. When water enters the terminal cover 50, water droplets (indicated by dashed lines) will flow through the top 22 of the vertical first boss 20 to the inclined surface 31 where the first boss 20 and the second boss 30 connect, thus leaving the terminal setting area. In this way, even if water flows into the terminal cover 50, there will be no water accumulation in the terminal setting area.

[0037] Because the speaker terminal housing structure of this application forms a boss structure on the shell, the boss structure can be stamped in the same direction as the shell during the subsequent stamping process. This allows the material's elongation rate to be controlled within a certain range, preventing tensile breakage. Since the boss structure has no limitations on height or depth, its size can be adjusted according to the number of terminals. Regardless of size, the boss can be integrally formed with the shell without disassembly and re-welding, facilitating automated manufacturing. Because the boss structure forms a stepped structure with the shell, and the connection point is shaped like an arc-shaped guide groove, it effectively blocks and guides water droplets. Furthermore, the raised boss structure in the middle prevents water accumulation.

[0038] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
