Description

Technical Field

[0001] The present disclosure relates to the electrical field, and in particular to a socket. Background Art

[0002] With the increasing popularity of household appliances, people have more and more demands on the use of household sockets, requiring not only that the sockets can conveniently provide power supply functions, but also that the sockets can have a variety of additional functions. For example, many household sockets currently have Universal Serial Bus (USB) power supply functions, that is, by combining the USB interface added to the socket with the circuit inside the socket, the USB power supply function is realized, and then mobile phones, tablet computers and other devices that need to be charged via the USB power supply protocol can be powered.

[0003] The existing socket with a USB interface usually includes an upper cover, a middle bracket, a circuit board assembly with a USB interface and a base, and there are two common assembly schemes. Among them, the first scheme is to first install the circuit board assembly to the base; then install the middle bracket to the base and let the USB interface on the circuit board assembly pass through the opening of the middle bracket; finally, cover the upper cover to encapsulate the middle bracket and the circuit board assembly in the accommodating cavity formed by the upper cover and the base. In the first scheme, when installing the middle bracket, it is necessary not only to align the USB interface on the circuit board assembly with the opening on the middle bracket so that the USB interface passes through the opening on the middle bracket, but also to align the connection position between the middle bracket and the base to achieve the fixed connection between the middle bracket and the base. Because both need to be taken into account at the same time, there is a certain degree of assembly difficulty, and the product assembly efficiency is low. The second scheme is to first fix the circuit board assembly to the middle bracket through a screw, and then install the circuit board assembly and the middle bracket together in the base. Although the second scheme can avoid positioning the USB interface and the opening, as well as the middle bracket bayonet and the edge of the base at the same time, the threaded connection still takes a lot of assembly time, and the product assembly efficiency is low. Utility Model Content

[0004] In order to solve the above technical problems, the present application proposes a socket of a new structure, which sets an elastic snap connection structure between the middle bracket and the circuit board assembly, so that during the assembly process, there is no need to consider the alignment of the circuit board assembly with the middle bracket and the middle bracket with the base at the same time, thereby effectively reducing the difficulty of assembly and improving the assembly efficiency of the product.

[0005] Based on this, in one aspect of the present disclosure, a socket is proposed, comprising: a middle-layer bracket, on which a through hole and an elastic snap-on portion are provided; a circuit board assembly, on which a limiting hole is provided, wherein the circuit board assembly is inserted into the through hole and is snap-connected with the elastic snap-on portion of the middle-layer bracket through the limiting hole; and a shell, wherein the middle-layer bracket and the circuit board assembly are arranged inside the shell.

[0009] In a preferred embodiment of the present disclosure, at least one and / or at least one type of universal serial bus interface is provided on the first circuit board.

[0010] In a preferred embodiment of the present disclosure, the circuit board assembly includes: a second circuit board, which is horizontally arranged below the middle support.

[0011] In a preferred embodiment of the present disclosure, a first interface and a second interface are provided on the first circuit board, and the first interface and the second interface are respectively located on two sides of the limiting hole.

[0012] In a preferred embodiment of the present disclosure, the shell includes an upper cover and a base, wherein a first snap-in position and a second snap-in position are provided on an edge of the base, the middle-layer bracket is fixedly connected to the base via the first snap-in position, and the upper cover is fixedly connected to the base via the second snap-in position.

[0013] In a preferred embodiment of the present disclosure, the socket includes: a socket blade assembly and a grounding frame assembly, and the socket blade assembly and the grounding frame assembly are deployed in a receiving groove on the middle bracket.

[0014] In a preferred embodiment of the present disclosure, the socket includes an anti-error component disposed between the socket blade component and the housing.

[0015] The socket with a novel structure proposed in the present disclosure sets an elastic buckle connection structure between the middle bracket and the circuit board assembly, so that the middle bracket can be connected to the circuit board assembly first, and then to the base, without the need for simultaneous alignment, which effectively reduces the difficulty of assembly and improves the assembly efficiency of the product. Furthermore, a transition port is designed at the elastic buckle portion of the middle bracket to reduce interference caused by the assembly path.

Therefore, the following specific description is not restrictive, and the scope of the present disclosure is defined by the attached claims.

[0022] Before introducing the embodiments of the present disclosure, some terms involved in the present disclosure are first explained to facilitate a better understanding of the present disclosure.

[0023] The terms "one", "a group" or "an" and the like used in the present disclosure do not indicate a quantitative limitation, but indicate the existence of at least one. The terms "include", "comprise" and similar terms used in the present disclosure should be understood as open terms, i.e. "include / include but not limited to", indicating that other contents may also be included. The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment" and the like. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0024] As mentioned above, in order to solve the technical problems of great difficulty and low assembly efficiency of sockets in the prior art, the present disclosure proposes a socket with a new structure, which can be a wall-mounted socket, a movable power strip or other types of sockets.

[0025] like Figure 1-2c As shown, an embodiment of the present disclosure provides an exemplary socket 100, wherein: Figure 1 is a schematic diagram of an exploded structure of an exemplary socket 100, Figure 2a is a schematic diagram of the structure of the middle bracket and the circuit board assembly of the exemplary socket 100 before assembly, Figure 2b FIG. 1 is a cross-sectional view of a middle bracket and a circuit board assembly of an exemplary socket 100 before assembly. Figure 2b FIG. 1 is a cross-sectional view of an exemplary socket 100 after the middle bracket and the circuit board assembly are assembled.

[0026] Specifically, the exemplary socket 100 includes a middle bracket 102, a circuit board assembly 104, and a housing 106. The middle bracket 102 is provided with a through hole 1022 and an elastic buckle portion 1024; the circuit board assembly 104 is provided with a limiting hole 1042. Moreover, the circuit board assembly 104 is inserted into the through hole 1022 and is buckled and connected with the elastic buckle portion 1024 on the middle bracket 102 through the limiting hole 1042. The middle bracket 102 and the circuit board assembly 104 are arranged inside the housing 106.

[0027] In some examples, the housing 106 includes an upper cover 1062 and a base 1064. The assembly process of the socket based on the novel structural design is as follows: first, insert the circuit board assembly 104 into the through hole 1022 of the middle bracket 102, and snap-connect with the elastic snap portion 1024 through the limiting hole 1042; then, connect the middle bracket 102 with the base 1064; finally, cover the upper cover 1062 on the middle bracket 102. In some examples, the edge of the base 1064 is provided with a first snap position 1066 and a second snap position 1068, the middle bracket 102 is fixedly connected with the base 1064 through the first snap position 1066, and the upper cover 1062 is fixedly connected with the base 1064 through the second snap position 1068.

[0028] In other examples, the housing 106 may also adopt an integrated structure. This structure integrates the upper cover and the base together, and is formed in one step by injection molding or other processes, which can not only improve the overall strength and stability of the socket, but also reduce production costs and assembly workload, and improve production efficiency.

[0029] In some examples, the elastic buckle portion 1024 of the middle bracket 102 includes a guide slope 1026, that is, the lower surface of the elastic buckle 1024 is a slope, which is used to make the buckle connection process between the middle bracket and the circuit board assembly smooth and reduce wear. Optionally, the number of elastic buckle portions and their positions on the middle bracket can be adjusted according to the actual needs of the product, and this example does not limit this.

[0030] Further, in some examples, the circuit board assembly 104 includes a transition opening 1044 opened along the insertion direction of the circuit board assembly (the direction of inserting into the through hole of the middle bracket). The transition opening has a guiding function, which can reduce the interference of the circuit board assembly in the process of inserting the middle bracket, and is particularly suitable for circuit board assemblies with a long insertion path. In some examples, a limiting rib 1043 is provided between the limiting hole 1042 and the transition opening 1044. Generally, the length of the limiting rib is not less than 2 mm to ensure the strength of the structure. Specifically, the elastic buckle part first passes through the transition opening. When it reaches the limiting rib, the limiting rib moves on the guide slope to push the elastic buckle part to one side until the elastic buckle part passes over the limiting rib and then snaps into the limiting opening. At this time, the elastic buckle part cooperates with the limiting rib to prevent the circuit board assembly from separating from the middle bracket, and the installation of the middle bracket and the circuit board assembly is completed. In other examples, there may be no transition opening on the circuit board assembly, only a limiting opening, and the elastic buckle part starts from the edge of the circuit board and slides on its surface to snap into the limiting opening, completing the installation of the middle bracket and the circuit board assembly.

[0031] In some examples, the circuit board assembly 104 includes a first circuit board 1046. The first circuit board 1046 is vertically inserted into the through hole 1022 of the middle bracket 102, and is snap-connected with the elastic snap-on portion of the middle bracket through a limiting hole. In other examples, the circuit board assembly 104 includes a first circuit board 1046 and a second circuit board 1048. The first circuit board 1046 is vertically inserted into the through hole 1022 of the middle bracket 102, and is snap-connected with the elastic snap-on portion of the middle bracket through a limiting hole, and the second circuit board 1048 is horizontally deployed below the middle bracket 102, and the second circuit board is mechanically and electrically connected to the first circuit board. It should be noted that the circuit board assembly 104 can have only one circuit board, or two or more circuit boards, and the circuit boards can be arranged horizontally or vertically, and can be specifically deployed according to the actual needs of the product, which is not limited in this application.

[0032] In some examples, an interface 105 is provided on the circuit board assembly. Optionally, the interface 105 can be a combination of any one or more of a serial interface, a parallel interface, an RJ45 interface, a USB interface, and / or other types of interfaces. Among them, the USB interface can be a Type-A interface, a Type-B interface, a Type-C interface, a Mini USB interface, and a Micro USB interface, etc. The interface 105 is provided on the first circuit board 1046, and the number of interfaces can be one, two, or more. The figure takes two USB interfaces as an example for illustration, but the application does not limit the number of interfaces.

[0033] In some examples, the first circuit board 1046 is provided with a first interface 1052 and a second interface 1054, wherein the first interface and the second interface are respectively located on both sides of the limiting hole 1042. In some examples, the first interface and the second interface are symmetrically arranged on both sides of the limiting hole. In some examples, the first circuit board is arranged at the end of the middle bracket to facilitate the deployment of other components in the middle.

[0034] In other examples, the circuit board assembly includes a third circuit board (not shown), on which a third interface and a fourth interface (not shown) are provided, and the first circuit board and the third circuit board are respectively provided at two ends of the middle bracket.

[0035] In some examples, the socket 100 includes a socket blade assembly 108 and a ground frame assembly 110, and the socket blade assembly 108 and the ground frame assembly 110 are disposed in a receiving slot on the middle bracket 102. In addition, the socket blade assembly 108 is electrically connected to the circuit board assembly through a wire.

[0036] In some examples, the socket 100 includes an anti-error component 112, which is disposed between the socket blade component 108 and the housing 106. The anti-error component 112 is a built-in safety mechanism of the socket, which requires both sides of the socket to be touched at the same time and requires a stronger operation to be powered on. This helps prevent current from being supplied to devices that should not be plugged into the socket, which can reduce the potential risk of electric shock.

[0037] In some examples, the socket 100 includes a thermally conductive silicone pad 114. The thermally conductive silicone pad 114 can accelerate the heat dissipation of the product, prevent the electrical product from overheating, aging or damage, and is particularly suitable for high-power sockets.

[0038] In some examples, the socket 100 includes a Mylar assembly 116. The Mylar assembly 116 in the socket mainly provides electrical isolation and reinforces insulation. In addition, the Mylar assembly 116 can also improve the mechanical strength and stability of the socket and prevent the socket from being deformed or damaged during use. In some specially designed sockets, the Mylar assembly can also serve to fix the circuit board or strengthen the conductive connection.

[0039] In some examples, the socket proposed in the present disclosure is a socket having at least a USB interface. The socket can be installed on a wall, the base is buried in the wall, and the power cord led out from the base is connected to an external power supply. The socket includes an upper cover, a middle bracket, a base and a circuit board assembly, and the circuit board assembly is arranged between the middle bracket and the base. The circuit board assembly includes a first circuit board arranged perpendicular to the middle bracket and a second circuit board arranged perpendicular to the first circuit board, and a USB interface is arranged on the first circuit board. The first circuit board is arranged at the end of the second circuit board, and the USB interface includes two TYPE-C interfaces. An elastic buckle portion is arranged on the middle bracket, and a guide slope is arranged on the lower surface of the elastic buckle portion. Openings are arranged on the first circuit board: a transition opening and a limit opening. A limit rib is arranged between the transition opening and the limit opening. When assembling the socket of this embodiment: first assemble the middle bracket and the circuit board assembly, align one end of the USB interface of the first circuit board with the through hole on the middle bracket, so that the end passes through the through hole and only needs to move forward; relatively, the elastic buckle part first passes through the transition opening, and when it reaches the limiting rib, the limiting rib moves on the guide slope to push the elastic buckle part to one side, until the elastic buckle part passes over the limiting rib and then snaps into the limiting opening, at this time the elastic buckle part cooperates with the limiting rib to prevent the first circuit board from separating from the middle bracket, completing the installation of the middle bracket and the circuit board assembly; then install the middle bracket and the circuit board assembly together into the base, at this time only need to align the bayonet on the four corners of the middle bracket with the edge of the base. In this way, the assembly difficulty is effectively reduced and the assembly efficiency is improved.
