Description

Technical Field

[0001] The utility model relates to the technical field of USB sockets, in particular to a USB socket for a docking station. Background Art

[0002] A docking station is a port replicator for electronic products such as laptop computers and desktop computers, which can extend the number of interfaces of the laptop to obtain better usability and protection for the commonly used interfaces of the laptop itself, and can plug in more interface devices.

[0003] Although the docking station can increase different types of sockets, the increase in the number of sockets will lead to an increase in the overall size of the docking station. In the types of USB sockets, there is also a type such as USB-b, and the usage frequency of this type of plug and socket is relatively low. In order to increase the types of sockets in the docking station, only this type of socket can be added. However, after using this socket in the docking station, other commonly used sockets cannot be reduced. Therefore, in order to achieve the diversity of plugging ports, only the overall size of the docking station can be increased. The increase in the overall size and the large occupied space of the docking station will affect the market share of the product. Therefore, the USB socket needs to be improved.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When the number of an element is referred to as having "a plurality", it can be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] The following will describe the present utility model in detail with reference to the embodiments shown in the accompanying drawings:

[0025] As Figures 1-4 shown, in this embodiment, a USB socket for a docking station is provided, which includes a housing and an insulator. A metal part is fixedly embedded in the insulator, and the metal part is used for power transmission. An insertion interface is opened on one side of the insulator, and the insertion interface is for the insertion of a USB-B plug. A positioning tongue piece and a connecting tongue piece integrally formed with the insulator are arranged in the insertion interface, and both the positioning tongue piece and the connecting tongue piece are provided with metal parts. The housing covers the outer side wall of the insulator. A through groove is opened at the insertion interface of the insulator, and the housing is provided with a crimping elastic piece. The crimping elastic piece extends into the insertion interface through the through groove. The crimping elastic piece has a certain resilience and can clamp the inserted plug to stabilize the connection between the plug and the present utility model. The two side walls of the insulator are recessed inward to form sliding buckle grooves, and the housing is provided with inwardly extending buckle elastic pieces. The buckle elastic pieces are buckled on the inner wall of the sliding buckle grooves. After the insulator is inserted into the housing, the buckle elastic pieces will control the insulator not to slide out, so as to ensure that the housing can well cover the insulator.

[0026] In this embodiment, the crimping spring sheets are stacked and arranged on both sides of one end of the shell, and the through grooves are arranged on both sides of the plug interface. The position of the crimping spring sheets corresponds to the position of the plug interface.

[0027] In this embodiment, the alignment tongue is located above the connecting tongue, and the hardware includes an end spring clip. The hardware is mainly an L-shaped structure, and its horizontal part extends to a part of the hardware and is horizontally extended and inserted into the alignment tongue and the connecting tongue. The end spring clips are symmetrically arranged on the upper and lower surfaces of the connecting tongue and extend protrusions upward and downward respectively. The hardware arranged inside the alignment tongue extends to the bottom surface of the alignment tongue.

[0028] In this embodiment, a downwardly extending empty groove is provided on the top surface of the insulator, which can save costs while ensuring the basic performance of the insulator.

[0029] In this embodiment, a rear cover is extended outward from one end of the top of the shell, and the rear cover is bent and covered behind the insulator. The rear cover is provided with multiple snap-fit openings, and the shell is provided with spring buckles extending outward, which are lifted outward and snap-fitted into the snap-fit openings.

[0030] In this embodiment, the two side walls of the shell are provided with an integrally formed elastic edge that curls outward. The utility model as a whole is mainly that the shell does not have too many redundant fasteners, and can make the best use of the internal space of the expansion dock to make room for other interfaces. Therefore, the types of interfaces of the expansion dock will not be reduced after using the utility model.

[0031] A limit block extending downward is arranged at the bottom of the insulator, and an extension groove is arranged on the shell. The limit block is buckled with the extension groove of the shell, which can ensure that the outer shell can be plugged in and installed with higher accuracy.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
