Description

Technical Field

[0001] The utility model relates to the field of equipment charging, in particular to a charging data transmission device. Background Art

[0002] An all-in-one charging and data transmission device (such as the application number 202322173257.4, named as a rotating flip-up electrical connector and its adapter), is a product with multiple functions suitable for connecting to different terminals to charge and transmit signals to the terminals.

[0003] At present, there is a connector on an all-in-one charging and data transmission device, the surface of which is covered with a shell, and the shell and the connector are fixed by glue. However, this fixing method is prone to glue leakage, which reduces the visual effect of the product.

[0004] For the above technical problems, such as Figure 1 As shown, Figure 1 The problem of preventing the shell from falling off is prevented by a physical structure between the shell and the connector. Specifically, the limiting shoulder N of the sleeve inside the connector cooperates with the groove M in the shell. During assembly, the shell is first put on the main part of the connector, and then the sleeve is assembled to the connector body. At this time, the limiting shoulder N on the sleeve matches the groove M of the shell. The limiting shoulder N will limit the shell and position the shell on the connector body. The ingenuity of this constraint method can easily achieve the positioning of the shell, with a simple structure and strong practicality.

[0005] However, such shells are all made by injection molding or casting. If they are to be made into a lower-cost profile, the groove M on the shell cannot be successfully made due to its small thickness.

[0006] Another technical problem is:

[0007] After the outer shell is put on the cover, there is still a certain gap between the two, and there will be relative looseness between the two. The pivot point for Type-A (or Type-C) to achieve the flipping action is the shaft installed in the slide slot. The assembly of the shaft on the slide slot is in the form of passing through and maintained on the slide slot. The looseness occurs when the inner wall of the outer shell contacts the shaft, affecting the smoothness of the interface flipping action. Utility Model Content

[0008] In order to solve the above problems, the utility model provides a charging data transmission device, which is provided with a physical connection structure suitable for being a part of a profile, thereby reducing the production cost.

[0009] The utility model provides a charging data transmission device, and the second technical problem to be solved is that the inner wall of the shell interferes with the rotating shaft and affects the smoothness of the flipping action.

[0018] Furthermore, a second opening corresponding to the first opening is provided on the surface of the first housing, so as to avoid the rotating component and avoid interfering with the rotation of the rotating component.

[0019] Furthermore, the rotating part is a rotating plate, which is made of metal material and has a certain elasticity. A positioning piece is provided on the inner side of the rotating plate, and bayonet holes are provided on both sides of the transmission device body. After the first connecting component is electrically connected to the second connecting component, the positioning piece is inserted into the bayonet hole to prevent the connection between the first connecting component and the second connecting component from being loose.

[0041] See also Figure 2-8 As shown, a charging data transmission device is used to power a terminal, and the charging data transmission device comprises a transmission device body 1, a casing 2, and a first casing 3, wherein one end of the transmission device body 1 is a first connecting component 4 connected to the terminal, the casing 2 is sleeved on the surface of the transmission device body 1 and exposes the first connecting component 4, and the first casing 3 is sleeved on the surface of the casing 2, wherein a snap-fit ​​structure is provided between the casing 2 and the transmission device body 1, and the purpose of connecting to each other is achieved through the snap-fit ​​structure, and the first casing 3 is sleeved on the surface of the casing 2.

[0042] The snap-fit ​​structure is composed of a card slot 51 on the inner side of the sleeve 2 and a card block 52 on the side of the transmission device body 1. After the sleeve 2 is put on the transmission device body 1, it is fixed on the transmission device body 1 by the snap-fitting of the card slot 51 and the card block 52, preventing the sleeve 2 from falling off the transmission device body 1.

[0043] A buckle 21 is provided on the inner side of the end of the first shell 3 away from the first connecting component 4, a second limiting shoulder 100 is provided on the surface of the transmission device body 1, and a positioning groove 25 is provided on the side of the transmission device body 1; the first shell 3 is sleeved on the outside of the sleeve 2, the buckle 21 is correspondingly stuck in the positioning groove 25, and the edge of the end of the first shell 3 is in contact with the second limiting shoulder 100, so as to fix the first shell 3.

[0044] It should be noted that the buckle 21 has an inclined surface 21 ′ with a slope moving in the assembly direction. There are two buckles 21 . The positioning groove 25 is formed by at least two convex ribs 25 ′ of the housing 2 . The buckle 21 is stuck between the two convex ribs 25 ′.

[0045] It also includes a group of rotating parts, and gaps are reserved between the two inner walls of the shell 2 and the transmission device body 1. One end of the rotating part is respectively installed between the inner wall of the shell 2 and the transmission device body 1, wherein, slide grooves 22 are provided on both sides of the shell 2, and a first opening portion 23 is formed between the two sides of the shell 2 and the top surface, and the first opening portion 23 and the rotating part correspond to each other. One end of the rotating part is installed in the slide groove 22 through a rotating shaft, and the second connecting component 6 installed on the other end of the rotating part can be rotated to an angle parallel to the first connecting component 4. The rotating part moves along the length direction of the slide groove 22, and the second connecting component 6 can be plugged into the first connecting component 4 and electrically connected to the second connecting component 6; the second connecting component 6 can also be detached from the first connecting component 4, and the second connecting component 6 can be rotated into the first opening portion 23 to display the first connecting component 4, thereby obtaining another charging interface of a different model.

[0046] When the first connecting component 4 is needed for charging, the second connecting component 6 is pushed to move the second connecting component 6 away from the first connecting component 4 along the length direction of the slide groove 22. After the rotating part moves to the first end 22a of the slide groove 22, the second connecting component 6 is rotated out to the top of the first connecting component 4 through the first opening 23. The first connecting component 4 that has been freed from the second connecting component 6 can be connected to the terminal to supply power to the terminal.

[0047] In this specific embodiment, the first connection component 4 is a Type-c interface, and the second connection component 6 is a Type-A interface. The second connection component 6 includes a second shell 63, and a first interface 61 and a second interface 62 fixed in the second shell 63. The first interface 61 and the second interface 62 are interconnected. When the first connection component 4 is connected to the second connection component 6, the second interface 62 is connected to the Type-c interface, so that the first interface 61 can power the terminal; the above description of the specific type of interface of the first connection component 4 and the second connection component 6 is only an implementation method of this scheme, and is not suitable for further limitation of this scheme. According to requirements, the first connection component 4 can be one of the lighting interface and the Type-A interface. Similarly, the second connection component 6 can also be various interfaces.

[0048] Of course, the surface of the first housing 3 is further provided with a second opening 31 corresponding to the first opening 23 , so as to avoid the rotating component and avoid interfering with the rotation of the rotating component.

[0049] The rotating component is a rotating piece 7, which is made of metal material and has a certain elasticity. A positioning piece 71 is provided on the inner side of the rotating piece 7, and bayonet holes 102 are provided on both sides of the transmission device body 1. After the first connecting component 4 is electrically connected to the second connecting component 6, the positioning piece 71 is inserted into the bayonet hole 102 to prevent the connection between the first connecting component 4 and the second connecting component 6 from being loose.

[0050] The upper surface and bottom surface of the transmission device body 1 are both provided with limiting bosses 101, and the top surface and bottom surface of the shell 2 are both provided with limiting grooves 24 matching the limiting bosses 101. After the shell 2 is sleeved on the transmission device body 1, the limiting bosses 101 and the inner sides of the limiting grooves 24 are against each other, ensuring that the shell 2 will not continue to move from the transmission device body 1 to the direction of the connecting line.

[0051] The above-mentioned terminals are various devices suitable for connecting components, such as mobile phones.

[0052] In this specific embodiment, the first housing 3 is formed of a zinc alloy material in one piece, and can certainly be formed of other plastic materials in one piece, or a zinc alloy material connected with a plastic material.

[0053] Furthermore, a supporting portion, which is a flange 26, is provided on the side of the sleeve 2. The flange 26 is pushed outward from the inner surface of the first shell 3 to prevent the sleeve 2 from affecting the use of the rotating piece 7. After the assembly is completed, a part of the structure of the rotating shaft on the rotating piece 7 passes through the slide groove 22 and is adjacent to the inner side surface of the first shell 3. Since there is a gap between the first shell 3 and the sleeve 2, the left and right shaking of the first shell 3 on the sleeve 2 will directly contact the rotating shaft, affecting the normal rotation of the rotating piece 7. The appearance of the flange 26 can prevent the shaking of the first shell 3 on the sleeve 2 and avoid the first shell 3 affecting the normal use of the rotating shaft.

[0054] Furthermore, the supporting portion may also be a protruding portion provided on the inner side surface of the first shell 3 .

[0055] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
