Description

Technical Field

[0001] This utility model relates to the field of dual-head card readers, and in particular to a novel dual-head card reader. Background Technology

[0002] With the widespread adoption of smartphones, digital cameras, drones, and other digital products, SD cards and TF cards have become the mainstream storage media. Meanwhile, the interfaces of personal computers, tablets, and other terminal devices are undergoing generational changes, with the traditional USB-A interface coexisting with the emerging Type-C interface. This has caused inconvenience for users exchanging data between different devices.

[0003] To meet these diverse needs, multi-in-one card readers integrating multiple card slots and output interfaces have emerged on the market. Among them, some cleverly designed dual-head card readers, through the detachable and reconfigurable male and female connectors, achieve switching between USB-A and Type-C interfaces within a compact size, gaining favor with users.

[0004] However, existing split or reconfigurable card readers suffer from a common structural flaw. When the male and female connectors are combined to form another interface, the connection between the two components often relies solely on the internal Type-C or USB data interface itself. These data interfaces are primarily designed for electrical signal transmission, and their mechanical strength and structural support capabilities are limited. During use, the physical stress generated by insertion, removal, twisting, or accidental impacts directly affects this fragile interface, easily leading to loosening, pin bending, or even breakage, significantly shortening the product's lifespan and reducing reliability.

[0005] Therefore, this utility model proposes a novel dual-head card reader to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of novel dual-head card readers, which rely solely on the data interface connection when used in combination, resulting in insufficient structural strength, easy damage to the interface, and easy loss of components after separation, this utility model aims to provide a novel dual-head card reader with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a novel dual-head card reader, comprising: a female head, a male head that can be plugged and detached from the female head, and a conversion component; it also includes a support component.

[0008] The conversion component includes a C-type output head on the female connector and a C-type interface on the male connector.

[0009] The support assembly includes a slide rail fixed to the female end and a slider fixed to the male end.

[0010] The slide rail is located on one side of the C-type output head and parallel to its insertion / removal direction, while the slider is correspondingly located on one side of the C-type interface. In this way, when the C-type output head is inserted into the C-type interface, the slider can slide synchronously and engage with the slide rail to form a stable mechanical support, providing additional physical reinforcement for the data interface.

[0011] Preferably, the conversion component further includes a USB output head on the male connector and a USB interface on the female connector.

[0012] More preferably, the USB output head is located at the end of the male connector away from the C-type interface, and the C-type output head is located at the end of the female connector away from the USB interface. This relative arrangement ensures that the two different combination adapter modes do not interfere with each other when plugged in, making the structure more reasonable and the operation clearer and more convenient.

[0013] Preferably, the female connector is also provided with a TF interface and an SD interface for reading memory cards. The provision of these two interfaces enables the present invention to directly read two mainstream memory cards without the need for other devices, which greatly enhances its functionality and practicality.

[0014] Preferably, the novel dual-head card reader further includes a connecting component for maintaining the connection between the female head and the male head. The connecting component includes an elastic cord with its two ends connected to the female head and the male head respectively to prevent accidental loss of either component.

[0015] More preferably, the connecting assembly further includes an extension post and a rotating ring. The extension post extends from one end of the female or male connector, and the rotating ring is rotatably connected to the outer wall of the extension post. One end of the elastic cord is connected to the rotating ring. This design with a rotating ring ensures that even if the user rotates the female or male connector at will, the elastic cord will not become tangled or twisted when the components are separated, thus ensuring flexibility of use.

[0016] Preferably, the slide rail is located on the outer surface of the female connector and the slider is located on the outer surface of the male connector. This external support structure simplifies the internal space design of the female and male connectors and reduces manufacturing difficulty and cost.

[0017] In one specific implementation, the slide rail is a guide groove extending along the length direction, and the slider is a protruding structure that can slide into the guide groove. This classic groove-block combination is simple in structure, provides precise guidance, and has a stable connection.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up mutually cooperating slide rails and sliders, forms a stable physical support structure when the male and female connectors of the card reader are combined, which solves the problem that existing split card readers rely solely on the data interface itself for connection, resulting in a fragile structure and easy damage and breakage of the interface, thus achieving the technical effect of improving the reliability and durability of the product connection.

[0019] 2. This utility model solves the problem that non-use parts are easily lost after being separated during use by setting a connecting component with an elastic rope and a rotating ring, thus achieving the technical effect of preventing parts from being lost and improving ease of use.

[0020] 3. This utility model cleverly integrates USB and Type-C interfaces onto a pluggable and reconfigurable male and female connector, achieving bidirectional conversion functionality. This solves the problem of users needing to carry multiple card readers or adapters for devices with different interfaces, achieving a high degree of functional integration and multi-purpose functionality.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides a novel dual-head card reader, which aims to solve the problems of insufficient structural strength, easy damage to the interface, and easy loss of components when the split card reader is used in combination and relies solely on the data interface for connection.

[0025] This novel dual-head card reader includes a female connector 1 and a male connector 2 that is detachable from the female connector 1. It also includes a conversion assembly 3 and a support assembly 5 disposed on the female connector 1 and the male connector 2. The conversion assembly 3 includes a Type-C output head 301 fixedly connected to the female connector 1 and a Type-C interface 303 fixedly connected to the male connector 2 and adapted to the Type-C output head 301. The support assembly 5, serving as a protective structure, includes a slide rail 501 fixed to the female connector 1 and a slider 502 fixed to the male connector 2. The slide rail 501 is fixed to the outer surface of the female connector 1; specifically, the slide rail 501 is disposed on one side of the Type-C output head 301 and parallel to its insertion / removal direction. The slider 502 is also fixed to the outer surface of the male connector 2. Correspondingly, the slide rail 501 is set on one side of the Type-C interface 303. The slide rail 501 has a guide groove extending along the length direction, and the slider 502 has a protrusion structure that can slide into the guide groove. This layout ensures that when the female connector 1 and the male connector 2 are connected, the slider 502 slides into the slide rail 501 at the same time as the Type-C output connector 301 is inserted into the Type-C interface 303. The two form a tight sliding fit relationship, thereby forming a stable mechanical support structure, providing positioning and support for the connection of the female connector 1 and the male connector 2, distributing the physical stress applied to the Type-C output connector 301 and the Type-C interface 303, and preventing the data interface from breaking due to uneven force.

[0026] To further prevent loss when components are separated, the new dual-head card reader also includes a connecting component 4, which keeps the female head 1 and the male head 2 always connected.

[0027] The structure of connecting component 4 will be described in detail below: The connecting component 4 includes an elastic cord 401, an extension post 402, and a rotating ring 403. The extension post 402 extends from one end of the female connector 1. The rotating ring 403 is rotatably connected to the outer wall of the extension post 402. One end of the elastic cord 401 is fixedly connected to the rotating ring 403, and the other end is fixedly connected to the male connector 2. When the female connector 1 and the male connector 2 are separated, the elastic cord 401 is stretched, and its elasticity keeps the two components together, preventing the accidental loss of either component. At the same time, the rotating ring 403 can rotate freely on the outer wall of the extension post 402, thereby ensuring that the female connector 1 and the male connector 2 connected by the elastic cord 401 can rotate freely without obstruction, avoiding cable tangling.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve rich conversion functions, the conversion component 3 also includes a USB output head 302 fixedly connected to the male head 2, and a USB interface 304 fixedly connected to the female head 1 and adapted to the USB output head 302. In order to optimize the layout to facilitate the plugging combination of different modes, the USB output head 302 is located at the end of the male head 2 away from the Type-C interface 303, while the Type-C output head 301 is located at the end of the female head 1 away from the USB interface 304. This relative layout ensures that the plugging operations of the two conversion modes do not interfere with each other.

[0029] As another preferred embodiment, in order to enable direct reading of the memory card, the outer shell sidewall of the female connector 1 is also provided with a TF interface 305 and an SD interface 306.

[0030] In terms of specific structural layout, the slide rail 501 is preferably set on the outer surface of the female head 1, and the slider 502 is also set on the outer surface of the male head 2 accordingly. This external design facilitates processing and simplifies the internal structure.

[0031] As a specific form of the support component 5, the slide rail 501 has a guide groove extending along the length direction, while the slider 502 has a protrusion that can slide into the guide groove. This groove and block matching form has a simple structure and a stable connection.

[0032] The working principle of this utility model is as follows: When female connector 1 and male connector 2 need to be used together, the Type-C output head 301 of female connector 1 is inserted into the Type-C interface 303 of male connector 2 for data connection. At the same time, the slider 502 fixed to male connector 2 also slides into the slide rail 501 fixed to female connector 1. The support component 5 formed by slider 502 and slide rail 501 provides precise physical positioning and stable structural support for the connection between female connector 1 and male connector 2. The external pressure generated during insertion, removal and use is borne by the support component 5, thereby reducing the stress at the Type-C output head 301 and effectively preventing accidental breakage of the data interface.

[0033] In use, first disconnect the female connector 1 from the male connector 2. Insert an SD card into the SD interface 306 of the female connector 1, or a TF card into the TF interface 305, as needed. Then, insert the Type-C output 301 of the female connector 1 into the Type-C interface 303 of the male connector 2 to form a complete USB card reader. At this point, the USB output 302 at the other end of the male connector 2 can be inserted into a device to complete the USB conversion. Alternatively, insert the USB output 302 of the male connector 2 into the USB interface 304 of the female connector 1 to form a Type-C card reader. Then, insert the Type-C output 301 at the other end of the female connector 1 into a device to complete the Type-C conversion. Through these two combination methods of the conversion component 3, a six-in-one effect is achieved.

[0034] When the female head 1 and the male head 2 are in a separated state, the connecting component 4 comes into play. The elastic rope 401 inside is stretched but always keeps the female head 1 and the male head 2 connected, effectively preventing the accidental loss of either component. At the same time, the rotating ring 403 connected to the elastic rope 401 can rotate freely on the outer wall of the extension column 402, ensuring the connection flexibility of the two components in the separated state and avoiding entanglement when pulled.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
