Description

Technical Field

[0001] The utility model relates to a socket, in particular to a waterproof terminal seat for a sound box. Background Art

[0002] Speakers are now common household appliances used to play music. As people's lives develop, the functions of speakers have also expanded, and they can be connected to a variety of audio sources through sockets for input signals (such as electric guitars and electronic keyboards using 6.35mm plug cables).

[0003] In the past, speakers were basically used indoors, so the sockets were not specially designed with waterproof structures. However, portable speakers are now often used outdoors. If it rains, rainwater will flow into the socket from the socket's connector hole, and then seep into the circuit board along the connector pins, causing short circuits or even burning.

For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

[0028] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.

[0029] Reference Figures 1 to 3 The utility model discloses a waterproof terminal seat for a speaker, comprising a socket housing 1 and a plug-in plate. The socket housing 1 is rectangular, and a round tube is arranged on one surface. The inner hole of the round tube is a plug-in hole 2. An end hole 4 is arranged on the end surface of the socket housing 1 opposite to the plug-in hole 2. The pin part 3 of the plug-in plate extends out through the end hole 4 and is bent ninety degrees. The end hole 4 is sealed by glue.

[0030] like Figure 4 As shown, the pin part 3 previously extended from the bottom surface of the socket housing 1, so in order to be assembled, the top surface of the socket housing 1 was open and closed by the top plate 5, and there would be a gap between the top plate 5 and the socket housing 1, which would cause water seepage, and there would be a gap between the pin part 3 and the socket housing 1, which would also cause water seepage, so if the previous structure required multiple places to be glued for sealing to achieve waterproofing, and the bottom surface is the surface in contact with the circuit board, if glue is to be applied on the bottom surface, not only the process requirements are high, but also the space is insufficient. However, the present application sets the end hole 4 on the end surface, which is not only convenient for assembly, but also the plug-in piece is installed into the socket housing 1 from the end hole 4, and then the end hole 4 can be directly glued and sealed, and the end surface is not the mounting surface in contact with the circuit board, so the glue application process requirements are low.

[0031] As shown in the figure, it also includes an end cover 6, which is located in the end hole 4 and closes the end hole 4. Of course, in order to avoid the pin part 3, the edge of the end cover has an avoidance hole corresponding to the size of the pin part 3, and the gap between the end cover 6 and the end hole 4 is sealed by glue, which can save glue and gluing time. As a further structure, a boss (not shown in the figure) is provided on the hole wall of the end hole 4, and the end cover 6 is positioned against the boss, which is convenient for assembly, and a square ring edge 7 is provided on the end cover 6. The ring edge 7, the surface of the end cover 6 and the hole wall of the end hole 4 together form a glue groove to accommodate glue, so that gluing is more accurate and convenient.

[0032] As shown in the figure, the socket housing 1 is provided with a guide groove 8, and the pin part 3 is stuck in the corresponding guide groove 8. The guide groove 8 is convenient for positioning the pin part 3 to prevent the pin part 3 from being offset and contacting. The guide groove 8 is located at the opening of the end hole 4 of the socket housing 1 and passes through the end hole 4.

[0033] As shown in the figure, the socket housing 1 is provided with a fixing plate 9, and the fixing plate 9 can be welded to the circuit board to fix the socket housing 1. Because the present application changes the lead-out position of the pin part and leads it out from the end hole 4, after the socket is plugged into the circuit board, the fixing point is concentrated at one end of the socket, which will cause the socket to be loosely fixed. Therefore, one end of the socket is fixed to the circuit board by the fixing plate 9, which ensures that the socket is firmly fixed.

[0034] As a further structure, the fixing plate 9 includes two oppositely arranged fixing feet 10, the socket housing 1 is located between the fixing feet 10, and the ends of the fixing feet 10 are welded to the circuit board. The fixing plate 9 of the above structure can be formed by punching and bending, and has a simple structure and is easy to process.

[0035] As a further structure, the socket housing 1 is provided with a card slot 11, and the fixing foot 10 is inserted into the card slot 11, and the card slot 11 is a T-shaped slot; the fixing foot 10 is provided with a spring sheet 12 that abuts against the groove wall of the card slot 11, and the fixing sheet 9 can be fixed by abutting against the groove wall of the card slot 11, thereby facilitating subsequent assembly and welding.

[0036] As shown in the figure, the socket housing 1 is provided with a rib 13, and the rib 13 is located on one side of the plug hole 2. When the socket is installed, it is convenient to set sealing cotton between the rib 13 and the speaker housing.

[0037] As shown in the figure, a slot (not shown in the figure) is provided on the inner wall of the plug hole 2, and the elastic plug part of the plug sheet (not shown in the figure) is stuck in the slot. The plug sheet of the present application is installed from the end hole 4, so in order to facilitate assembly and positioning, a slot is provided, one end of the slot passes through the socket housing 1, and the elastic plug part can be directly stuck in the slot. The structure of the elastic plug part is the same as before, and is used to contact and conduct electricity with different segments of the plug, so the specific structure is not described in detail.

[0038] The waterproof terminal seat for a speaker provided by an embodiment of the utility model is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the method of the utility model and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
