Description

Technical Field

[0001] The present application relates to the technical field of household sockets, and in particular to a USB socket. Background Art

[0002] Nowadays, electronic technology is developing rapidly, and there are more and more household appliances. Traditional wall sockets can no longer meet the needs of consumers. The emergence of adapter sockets makes up for this defect. It is provided with various types of sockets for plugging in to charge electronic products. The existing adapter socket includes a socket body and a plug connected to the socket body. The socket body includes an upper cover plate and a lower cover plate fixed together. The upper cover plate is provided with a plurality of sockets for plugging in to the plug.

[0003] The conventional socket structure usually has two or three holes on the surface of the socket body to adapt to the plug of the electrical appliance. Related prior art, such as Chinese patent application "Multi-function adapter socket", application number: CN201520900390.8, discloses a multi-function adapter socket for connecting with two specifications of docking plugs to charge electronic products. The multi-function adapter socket includes a socket body and a plug connected to the plug body, the socket body includes an upper cover and a lower cover fixed together, a grounding plate and a pair of conductive plates located between the upper cover and the lower cover, and a shielding plate assembled on the upper cover. The upper cover is provided with a plurality of grooves and a first plugging hole, a second plugging hole and a pair of third plugging holes located in the grooves. The distance between the first plugging hole and the third plugging hole is greater than the distance between the second plugging hole and the third plugging hole. The shielding plate is provided with a first through hole corresponding to the second plugging hole and a second through hole corresponding to the third plugging hole. After the shielding plate is assembled to the upper cover, it covers the first plugging hole, which can be used for two specifications of docking plugs to be connected. There is no need to purchase two specifications of adapter sockets, which saves costs and saves usage space.

[0004] However, more and more electrical appliances are currently using USB data cables for charging / powering, and in order to save resources, many businesses only provide data cables to users, and no longer provide plugs connected to the data cables. Therefore, in order to meet the needs of users, the socket also needs to add a USB interface on its surface for connecting to the data cable to power the electrical appliances. In addition, in the prior art, the socket simply opens a hole on the outer shell to allow the power cord to pass through, and no additional fixing structure is provided for the power cord. Then, if the power cord is subjected to excessive external force, it will cause problems such as the electrical connection contacts of the power cord inside the socket falling off or poor contact. And adding an additional fixing structure to fix the power cord will significantly increase the overall cost of the socket. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide a USB socket, wherein an extruded part is added inside the upper cover, and a corresponding supporting part is added inside the lower cover, and a power cord passes through and is fixed between the supporting part and the extruded part, thereby achieving low-cost fixed installation of the power cord without the need for additional assembly steps.

[0006] The technical solution adopted in the present application is: a USB socket, comprising an upper cover and a lower cover connected to form an inner cavity, the inner top surface of the upper cover is provided with an extrusion member, the inner bottom surface of the lower cover is provided with a support member, the support member and the extrusion member are arranged opposite to each other, the support member and the extrusion member both act to form a channel for the power cord to pass through, and the support member and the extrusion member both act on the surface of the power cord.

[0007] Compared with the prior art, the advantages of the present application are that, firstly, an extrusion is provided on the inner top surface of the upper cover, and a support is provided on the inner bottom surface of the lower cover. The power cord passes through the extrusion and the support. The extrusion and the support exert force on the surface of the power cord, thereby pressing the power cord. This prevents the power cord from being subjected to force in the external environment, which directly affects the connection effect of the electrical connection in the inner cavity. Secondly, the present application directly sets the extrusion on the upper cover and the support in the lower cover. During assembly, no additional assembly steps are required, effectively saving assembly costs.

[0008] In some embodiments of the present application, the support member includes a lower outer frame and at least two support sheets. The support sheets are arranged in the middle of the lower outer frame, and there is a spacing between two adjacent support sheets.

[0009] In some embodiments of the present application, the extruded component includes an upper outer frame and at least two extruded sheets. The extruded sheets are arranged in the middle of the upper outer frame, and there is a spacing between two adjacent extruded sheets.

[0010] In some embodiments of the present application, the support sheet and the extrusion sheet are staggered front to back along the axial direction of the channel.

[0011] That is, the support sheet is located between two adjacent extrusion sheets. When the support sheet and the extrusion sheet that are staggered from each other exert force on the power cord, a certain elastic deformation space is provided to the power cord, so that the power cord will not be crushed to death.

[0012] In some embodiments of the present application, the upper cover is connected to the lower cover, and the upper outer frame is pressed against the lower outer frame. The upper outer frame and the lower outer frame can prevent the support sheet and the extrusion sheet from being too close to each other, so that the power cord is excessively squeezed.

[0013] In some embodiments of the present application, the top surface of the support sheet is provided with a concave support groove, and the support groove includes two left and right inclined edges, and the angle between the left and right inclined edges is an obtuse angle. The structural setting of the two inclined edges in the support groove enables the power cord to be aligned after being laid, and then the upper cover is installed for pressing.

[0014] In some embodiments of the present application, the bottom surface of the extrusion sheet is provided with an upward concave extrusion groove, and the extrusion groove is a polygonal structure. Specifically, the extrusion groove is a semi-octagonal structure.

[0015] In some embodiments of the present application, a through hole for the power cord to pass through is opened on the side surface of one end of the upper cover and the lower cover, and the extrusion member and the support member are arranged close to the through hole.

[0016] In some embodiments of the present application, the upper cover surface is sequentially arranged with a USB interface group, multiple socket groups and a switch, and the inner cavity is correspondingly arranged with a USB power supply device and multiple child protection components, and the multiple child protection components are connected to the USB power supply device through a conductive sheet and a grounding clamp.

[0017] In some embodiments of the present application, an indicator light is also arranged on the surface of the upper cover, and a surge plate is correspondingly arranged in the inner cavity.

[0018] The above-mentioned implementation modes can be combined arbitrarily based on the common knowledge in the art. BRIEF DESCRIPTION OF THE DRAWINGS
