This utility model adds a retainer, and the connecting screw holes are located inside the speaker housing and do not penetrate it. Therefore, the screws and holes are not exposed outside the speaker housing. The retainer is fixed to the speaker housing, and the socket is only pressed into the speaker housing by the retainer, resulting in a smooth and aesthetically pleasing outer surface of the speaker housing.

Description

Technical Field

[0001] This utility model relates to a socket, and more particularly to a convenient power connection structure for a speaker. Background Technology

[0002] An AC socket is an electronic component used to connect to AC power sources. It can transmit the voltage and current of the AC power source to electrical appliances, enabling the power supply and control of the appliances.

[0003] The speaker also needs an AC socket. One end of the AC socket connects to an external power source, while the other end connects to the power cord inside the speaker via male and female terminals. One type of AC socket has a built-in screw hole in its casing, requiring a through-hole in the speaker casing for installation. Screws are inserted from the outside of the casing to engage with the screw hole and secure the AC socket. However, this design requires openings in the casing, which not only compromises the aesthetics but also hinders the sealing of the speaker's interior. Another type of AC socket lacks a screw hole, but it cannot be directly fixed to the speaker casing. Therefore, to solve these problems, the applicant has designed a convenient power connection structure for the speaker. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a convenient power supply connection structure for speakers.

[0031] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0032] Reference Figures 1 to 7This utility model discloses a convenient power connection structure for a speaker, including a speaker housing 1, a socket 2 (the socket 2 is a conventional AC socket 2, so its specific structure is not described in detail), and a base sleeve 3. One end of the socket 2 can be inserted into the base sleeve 3. Of course, the speaker housing 1 has a plug interface 4. The other end of the socket 2 is positioned and engaged with the plug interface 4, so that one side of the positioning ring edge 5 of the socket 2 can abut against the inner wall of the speaker housing 1, and the end face of the base sleeve 3 can abut against the other side of the positioning ring edge 5 of the socket 2. When the base sleeve 3 is fixed to the speaker housing 1 by connecting fasteners, it can also press the socket 2 into the speaker housing 1 at the same time. Therefore, the screws and holes are all inside the speaker housing 1 and are not exposed. The base sleeve 3 is fixed to the speaker housing 1, and the socket 2 is only pressed into the speaker housing 1 by the base sleeve 3. Therefore, the outer surface of the speaker housing 1 is smooth and beautiful.

[0033] As shown in the figure, the specific structure is as follows: the outer wall of the seat 3 is provided with a connecting plate 6, the connecting plate 6 is provided with a connecting through hole 7, the speaker housing 1 is provided with a connecting screw hole 8, and the connecting fastener is a connecting screw (not shown in the figure). The connecting screw is connected to the connecting screw hole 8 through the connecting through hole 7, thereby fixing the seat 3 to the speaker housing 1. The above structure is simple, and the fixing by connecting screws is not only firmly fixed, but also easy to disassemble and maintain.

[0034] As a further preferred structure, a sealing cotton 9 is provided between the positioning ring edge 5 and the inner wall of the speaker housing 1. In this way, when the socket 2 is locked, the sealing cotton 9 also comes into close contact with the inner wall of the speaker housing 1 and the positioning ring edge 5, thereby achieving a seal and ensuring the airtightness of the speaker housing 1.

[0035] As shown in the figure, the seat cover 3 is provided with several positioning blocks 10 that can slide in contact with the plug-in. The end of the positioning block 10 is provided with a guide slope. Because the socket 2 and the seat cover 3 need to make contact as required, the positioning block 10 can reduce the contact area, thereby facilitating assembly. Moreover, the end of the positioning block 10 is provided with a guide slope to facilitate the insertion of the socket 2 into the seat cover 3.

[0036] As shown in the figure, it also includes a plug-in 11, which is located inside the seat cover 3 and fixed to the seat cover 3 by a snap-fit ​​structure. Previously, our company would first install the AC socket 2, and then directly insert the pins that connect to the power cord inside the speaker into the socket of the AC socket 2, and then fix it by soldering. The above process is relatively troublesome in assembly. However, if the plug-in 11 is directly plugged into the socket 2, the plug-in 11 cannot be fixed. Therefore, now the pins are fixed inside the plug-in 11 first, and then the plug-in 11 is fixed to the seat cover 3 by a snap-fit ​​structure, so that the pins can be inserted into the socket. The above structure is very convenient in assembly, and the assembly of the plug-in 11 and the pins can be achieved by mechanized equipment, which is highly efficient.

[0037] As shown in the figure, the buckle structure includes an elastic plate 12 disposed on the outside of the plug-in 11 and an insert plate 13 disposed inside the seat sleeve 3. The elastic plate 12 is provided with a first locking block 14, and the insert plate 13 is provided with a second locking block 15. When the insert plate 13 can be inserted between the plug-in 11 and the elastic plate 12, the second locking block 15 will squeeze the first locking block 14 to cause the elastic plate 12 to bend and deform. When the second locking block 15 is completely squeezed into the space between the plug-in 11 and the elastic plate 12, the elastic plate 12 and the first locking block 14 are reset so that the first locking block 14 and the second locking block 15 are locked together.

[0038] As shown in the figure, the snap-fit ​​structure includes a connecting plate 16. The elastic plate 12 is fixed to the outside of the plug-in 11 via the connecting plate 16. The connecting plate 16 provides space between the elastic plate 12 and the plug-in 11, facilitating the insertion of the insert plate 13 and the second locking block 15, while also saving materials. As a preferred structure, a guide plate is provided on the outside of the plug-in 11 to guide the insert plate 13, thus facilitating the insertion of the insert plate 13 between the elastic plate 12 and the plug-in 11.

[0039] As shown in the figure, the plug-in 11 includes a terminal housing 17. The terminal housing 17 is provided with a partition plate 18 to divide the terminal housing 17 into several receiving holes 19. The bottom of the receiving hole 19 is provided with a terminal hole 20. The above structure is designed according to the structure of a common terminal block, which is used to connect the plug-in 11 to the pin. The pin is located in the receiving hole 19 and exposed through the terminal hole 20. The receiving hole 19 can be filled with glue. The above structure can realize mechanized assembly, thus achieving high efficiency.

[0040] During installation, the socket 2, sealing cotton 9 and seat 3 are first assembled, and then the three are fixed together inside the speaker housing 1. Then the plug 11 is inserted into the seat 3 and snapped into place, while the pin is inserted into the socket, thus completing the assembly.

[0041] The present invention provides a detailed description of a convenient power supply connection structure for a speaker according to the embodiments of the present invention. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
