[0058] Hereinafter, the present invention will be described in detail by illustrating various embodiments of the present invention with reference to the drawings. However, the inventive concept may be embodied in many different forms and should not be construed as being limited to the embodiments described herein. In addition, the same reference numerals may be used to represent similar elements in the drawings.

[0059] Please refer to Figure 1 , which is an exploded schematic diagram of an embodiment of the present invention, as shown in the figure. The floating connector 1 disclosed in the present invention also includes a connector seat 10, a connector body 20, a shell member 21 disposed on the connector body 20, a plurality of S-shaped conductive terminals S1 and a tongue connector 30.

[0060] Please refer to Figure 2 , which is a stereoscopic diagram of a connector seat according to an embodiment of the present invention. As shown in the figure, the connector seat 10 has a seat opening O1, and the seat opening O1 contains a plurality of conductive terminals 12. Each conductive terminal 12 is at the bottom of the connector seat 10, exposing a terminal connection portion 121 that can be connected to an electronic device. A plurality of conductive terminal tracks A12 for accommodating the conductive terminals 12 are also provided inside the connector seat 10.

[0061] More specifically, in the present invention Figure 2 In the disclosed embodiment, when the connector seat 10 is connected to the connector body 20, the tongue connector 30 is accommodated inside the seat opening O1, and the tongue opening 32 covers the opening portion of the connector seat 10, wherein the protrusion SC of the S-shaped conductive terminal presses against the conductive terminal, thereby forming an electrical connection between the connector seat 10 and the connector body 20.

[0062] The bottom cross-sectional area of ​​the connector seat 10 is larger than the cross-sectional area of ​​the seat opening O1, and the change in the cross-sectional area of ​​the connector seat 10 corresponds to the formation of a seat bevel 11 on the outer shell of the connector seat 10. In some embodiments of the present invention, when the connector seat 10 is connected to the connector body 20, the seat bevel 11 abuts against the tongue opening bevel edge 321 that is exposed inside the tongue opening 32 due to the expansion of the tongue opening. In other words, during the process of the connector seat 10 and the connector body 20 approaching each other, the arrangement of the base bevel 11 and the tongue opening bevel edge 321 can prevent the internal damage of the floating connector 1 caused by the deformation of the connector seat 10 and the connector body 20 under stress.

[0063] Among them, in some embodiments of the present invention, the seat body bevel 11 and the tongue opening bevel edge 321 only serve as a buffer to prevent the connector seat body 10 or the connector body 20 from being deformed by external force after connection, rather than fixing the connection position of the connector seat body 10 and the connector body 20 by the seat body bevel 11 and the tongue opening bevel edge 321.

[0064] Please refer to Figure 3A and Figure 3B , which are respectively a first-view stereoscopic view of a connector body according to an embodiment of the present invention and a second-view stereoscopic view of a connector body according to an embodiment of the present invention. As shown in the figure, the connector body 20 includes: a shell 21, a plurality of S-shaped conductive terminals S1, and a tongue connector 30. The shell 21 is an annular frame, and the bottom of the shell 21 has a plurality of shell terminal openings W22.

[0065] Please refer to further Figure 3B , wherein bottom openings A2 are respectively provided on both sides of the bottom of the outer shell 21, and a short U-shaped metal component U2 is respectively provided in each bottom opening A2, one end of the short U-shaped metal component U2 is inserted into the bottom opening A2, and the other end is attached to the side edge of the outer shell 21.

[0066] One end of each of the S-shaped conductive terminals S1 passes through a housing terminal opening W22. The tongue connector 30 has a plurality of tongue terminal openings W31, a tongue opening 32 and a tongue component 33. The tongue component 33 is disposed in the tongue opening 32 and extends from the inside of the tongue connector 30 to the tongue opening 32.

[0067] Please refer to further Figure 4 , which is an exploded schematic diagram of a connector body according to an embodiment of the present invention. As shown in the figure, a plurality of tongue terminal channels 331 are provided on the surface of the tongue component 33, and the other end of each S-shaped conductive terminal S1 passes through a tongue terminal opening W31 and floats on each tongue terminal channel 331. By providing the S-shaped conductive terminal, the housing 21 and the tongue connector 30 are firmly connected.

[0068] Furthermore, the shell member 21 floats relative to the tongue connector 30 within the deformation range of the multiple S-type conductive terminals S1. When the connector body 20 is connected to the connector seat 10, each S-type conductive terminal S1 and each conductive terminal 12 will also maintain electrical connection in a floating state.

[0069] In some embodiments of the present invention, the connector seat 10 and the connector body 20 form an electrical connection by contacting the conductive terminal 12 with a portion of the S-type conductive terminal S1 floating on each tongue terminal channel 331, wherein the S-type conductive terminal S1 has a clamping protrusion SC, which further provides clamping force between the S-type conductive terminal S1 and the conductive terminal 12, making the electrical connection between the S-type conductive terminal S1 and the conductive terminal 12 more stable.

[0070] In more detail, in some embodiments of the present invention, the inner edge of the tongue opening 32 may also be provided with a plurality of inner edge protrusions 322. When the connector seat 10 is inserted into the connector body 20, the plurality of inner edge protrusions 322 provided in the tongue opening 32 press against the outer periphery of the seat opening O1, thereby increasing the friction between the tongue opening 32 and the seat opening O1, so that the tongue opening 32 and the seat opening O1 are clamped more firmly. Among them, in some embodiments of the present invention, the inner edge protrusions 322 may be a strip setting perpendicular to the seat opening O1, a dot distribution, or a structural setting with dotted stripes, etc., to increase the friction between the tongue opening 32 and the seat opening O1.

[0071] Furthermore, a housing recess R1 is provided on both sides of the upper surface of the housing 21, and a side protrusion 34 is provided on both sides of the tongue connector 30. When the housing 21 and the tongue connector 30 are combined via each S-shaped conductive terminal S1, the side protrusion 34 is accommodated in the housing recess R1.

[0072] Among them, each shell component recess R1 is also provided with two shell component notches A1. Through the provision of the shell component notches A1, when the shell component 21 and the tongue connector 30 are combined through each S-shaped conductive terminal S1, and the side protrusion 34 is accommodated in each shell component recess R1, the two ends of the long U-shaped metal component U1 can be fixed on the shell component recess R1 through each shell component notch A1 located in the same shell component recess R1, and the bottom long edge U11 of each long U-shaped metal component U1 respectively covers each side protrusion 34.

[0073] Please refer to the outer shell 21 again. Bottom openings A2 are respectively set on both sides of the bottom of the outer shell 21. A short U-shaped metal component U2 is set in each bottom opening A2. One end of the short U-shaped metal component U2 is inserted into the bottom opening A2, and the other end is attached to the side edge of the outer shell 21, so as to cooperate with the long U-shaped metal component U1 to form a semi-enclosed conductive shell on the outer shell 21.

[0074] In some embodiments of the present invention, the S-shaped conductive terminal S1 has a first S-end portion S11 and a first S-end long edge S111 attached to the lower edge of the tongue connector 30 .

[0075] Furthermore, the S-shaped conductive terminal S1 has a second S-end portion S12 . The second S-end portion S12 is located between the tongue connector 30 and the housing 21 . The height of the side wall of the housing 21 is higher than that of the second S-end portion S12 .

[0076] Please refer to further Figure 5, which is a deformation diagram of an S-shaped terminal according to an embodiment of the present invention. The S-shaped conductive terminal S1 is accommodated between the housing member 21 and the tongue connector 30, and the S-shaped conductive terminal S1 is deformed between 10% and 30% of the lateral spacing between the first S end S11 and the second S end S12. However, the embodiments of the present invention are not limited thereto. The deformation range of the S-shaped terminal is affected by the material, and it can also be set to deform in the vertical spacing direction. For example, it is deformed between 10% and 30% of the vertical spacing between the first S end S11 and the second S end S12.

[0077] The present invention further discloses a connection mechanism assembly suitable for providing a floating connection for an electronic device, which includes a first connection device, a second connection device and a plurality of S-type terminal components, wherein the first connection device includes a first connection protrusion component, the second connection device includes a second connection opening component compatible with the first connection protrusion component, and the second connection device is connected to the first connection device via the first connection protrusion component and the second connection opening component.

[0078] Among them, multiple S-type terminal components are arranged on the first connecting device to connect the first connecting protrusion and the first connecting device, or are arranged on the second connecting device to connect the second connecting device and the second connecting opening component. When the first connecting device is provided with multiple S-type terminal components, the second connecting device and the second connecting opening component are connected through multiple conductive terminal 12 components.

[0079] When the first connection device is provided with a plurality of S-shaped terminal components, the second connection opening component is provided on the second connection device, and the second connection opening component is provided with a plurality of conductive terminal components. When the second connection device is provided with a plurality of S-shaped terminal components, the first connection protrusion component is provided on the first connection device, and the first connection protrusion component is provided with a plurality of conductive terminal components.

[0080] The deformation range of multiple S-shaped terminal components arranged in the first connecting device when subjected to force deformation is the first deformation range, and the deformation range of multiple S-shaped terminal components arranged in the second connecting device when subjected to force deformation is the second deformation range. By setting up multiple S-shaped terminal components, the connection mechanism assembly of the present invention maintains the electrical connection between multiple S-shaped terminal components and multiple conductive terminal components within the first deformation range or the second deformation range.

[0081] Among them, the first deformation range and the second deformation range are affected by the connection method of the first connecting device and the second connecting device and the application field. For example, it can be between 10% and 30% of the lateral spacing and vertical spacing between the first S end and the second S end of the S-shaped conductive terminal component.

[0082] By setting up the connection mechanism assembly of the present invention, a device equipped with the connection mechanism assembly of the present invention, for example, a vehicle device, can be used. Even if the road is not stable and the electronic device in the vehicle is subjected to irregular vibrations while the vehicle is moving, the connection mechanism assembly can maintain the electrical connection between the multiple S-shaped terminal components and the multiple conductive terminal components within the first deformation range or the second deformation range to keep the device operating. In this way, the irregular force on the connection mechanism assembly does not affect the operation of the connection mechanism assembly, or reduces the effect of the irregular force on the operation of the connection mechanism assembly. However, the connection mechanism assembly of the present invention is not limited to use in vehicle devices, but is also suitable for use in other devices that may be subjected to irregular force directions and force magnitudes to maintain electrical connections between devices.

[0083] In some embodiments of the present invention where the first connecting device and the first connecting protrusion part are connected via a plurality of S-shaped terminal members, a long U-shaped member may be provided on both sides of the first connecting device, respectively, and each long U-shaped member covers the side edges of the first connecting device and the first connecting protrusion part respectively; by providing the long U-shaped member, when the S-shaped conductive terminal is deformed by force and affects the connection between the first connecting device and the first connecting protrusion part, the long U-shaped member further stabilizes the first connecting protrusion part in the first connecting device and connects to the long U-shaped member, until the long U-shaped member covers the first connecting protrusion part and moves within the range, thereby further preventing the first connecting protrusion part from separating from the first connecting device.

[0084] Alternatively, in some embodiments of the present invention where the second connecting device and the second connecting opening part are connected via a plurality of S-shaped terminal components, long U-shaped components may also be provided on both sides of the second connecting device, respectively, and each long U-shaped component respectively covers the side edges of the second connecting device and the second connecting opening part; by providing the long U-shaped components, when the S-shaped conductive terminal is deformed by force and affects the connection between the second connecting device and the second connecting opening part, the long U-shaped component further stabilizes the movement of the second connecting opening part within the range from when the second connecting device is connected to the long U-shaped component to when the long U-shaped component covers the second connecting opening part, thereby further preventing the second connecting opening part from being separated from the second connecting device.

[0085] In summary, by configuring the S-shaped conductive terminal of the present invention, the connector seat and the connector body have a range of force deformation when in the connected state, so that the connector seat and the connector body are floatingly connected. In addition, by configuring the long U-shaped metal component, when the tongue connector is subjected to a force exceeding the bearing limit of the S-shaped conductive terminal, the long U-shaped metal component can prevent the tongue connector and the outer shell from separating from each other, thereby providing the connector with the function of maintaining signal connection.

[0086] In addition, in a device equipped with the connection mechanism assembly disclosed in the present invention, even if the device is subjected to irregular force, the electrical connection between multiple S-type terminal components and multiple conductive terminal components can be maintained within the first deformation range or the second deformation range of the S-type conductive terminal component to keep the device operating.

[0087] Although the embodiments of the present invention are disclosed as described above, they are not intended to limit the present invention. Any person skilled in the relevant art may make slight changes to the shapes, structures, features, methods and quantities described in the claims of the present invention without departing from the spirit and scope of the present invention.
