Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically, to a floating connection structure. Background Technology

[0002] In existing technologies, when pluggable connectors are used to electrically connect to external devices, the conductive components of the device are typically inserted directly into the connector's interface to achieve the connection. However, the size of the connector interface is usually matched to, or slightly larger than, the conductive components, thus requiring proper positioning for optimal insertion. When there is a misalignment, the conductive components cannot be properly inserted into the connector interface, affecting connection efficiency. Furthermore, blind insertion can easily damage the conductive plates within the interface, thus impacting the connector's lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a floating connection structure that facilitates device insertion and is not easily damaged by impact.

[0004] The technical solution adopted by the floating connection structure disclosed in this invention is:

[0005] A floating connection structure includes a housing, the housing having a first interface, and an electrical connection assembly inside the housing. The electrical connection assembly includes a first conductive end disposed on the housing and a conductive connector connected to the first conductive end. The first conductive end has a second interface that connects to the first interface, and the first inner wall of the first interface is an inclined surface that opens outward from the first interface.

[0006] As a preferred embodiment, the first conductive end includes a guide member disposed within the housing, the second interface is opened on the guide member, the guide member is also provided with an interface mounting groove communicating with the second interface, one end of the conductive connector is disposed within the interface mounting groove, and the second inner wall of the second interface is an inclined surface that opens outward toward the second interface.

[0007] As a preferred embodiment, the guide member is movable relative to the housing, and the conductive connector includes a first conductive plate disposed in the interface mounting groove, an elastic conductive plate connected to the first conductive plate, and a second conductive plate connected to the elastic conductive plate, wherein the second conductive plate is used for fixed installation.

[0008] As a preferred embodiment, the elastic conductive plate is wavy in the insertion direction of the first interface.

[0009] As a preferred embodiment, the guide member has a guide protrusion on its side, and the inner wall of the housing has a matching guide groove, wherein the depth of the guide groove in the direction perpendicular to the insertion direction of the first interface is greater than the length of the guide protrusion.

[0010] As a preferred embodiment, both the first and second conductive plates are rigid copper busbars, and the elastic conductive plate is a flexible copper busbar.

[0011] As a preferred embodiment, the first conductive plate includes a first plate body disposed in the interface mounting groove and a fixing plate. The first plate body is provided with a first conductive sheet, and the fixing plate has a hollow groove that matches the position of the first conductive sheet. The fixing plate presses down on the first conductive sheet and is fixed to the first plate body.

[0012] As a preferred embodiment, the first conductive sheet includes a connecting portion disposed on the first plate and a plurality of conductive portions disposed on the connecting portion and in an arc shape, the plurality of conductive portions being spaced apart, the fixing plate pressing the connecting portion and fixing it to the first plate, the conductive portions being exposed in the hollow groove.

[0013] As a preferred embodiment, the connecting part has a gap for separating the connecting part in the direction perpendicular to the insertion direction of the first interface, and the two ends of the conductive part are respectively located on the connecting parts on both sides of the gap.

[0014] As a preferred embodiment, the width of the second interface in the vertical direction matches the width of the part to be inserted, and the width of the second interface in the horizontal direction is slightly larger than the width of the part to be inserted.

[0015] The beneficial effects of the floating connection structure disclosed in this invention are as follows: When an external device needs to be inserted into the second interface of the first conductive terminal to achieve an electrical connection, it first needs to be inserted into the first interface. If there is a positional deviation between the external device and the second interface, the external device will first collide with the first inner wall of the first interface. Since the first inner wall of the first interface is an inclined surface that opens outward from the first interface, the external device slides along the first inner wall of the first interface to the second interface after the collision and is then inserted into the second interface to achieve an electrical connection. Through the buffering and guiding effect of the first interface, it is easier for the device to be inserted, and the second interface is less likely to be damaged by impact.

[0021] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The floating connection structure includes a housing 10, which has a first interface 12. An electrical connection assembly is located within the housing 10. The electrical connection assembly includes a first conductive end 20 disposed on the housing 10 and a conductive connector 30 connected to the first conductive end 20. The first conductive end 20 has a second interface 22 that connects to the first interface 12. The first inner wall 122 of the first interface 12 is an inclined surface that opens outward from the first interface 12.

[0023] When an external device needs to be inserted into the second interface 22 of the first conductive terminal 20 to establish an electrical connection, it must first be inserted into the first interface 12. If there is a positional deviation between the external device and the second interface 22, the external device will first collide with the first inner wall 122 of the first interface 12. Since the first inner wall 122 of the first interface 12 is an inclined surface that opens outward from the first interface 12, the external device slides along the first inner wall 122 of the first interface 12 to the second interface 22 after the collision and is then inserted into the second interface 22 to establish an electrical connection. The buffering and guiding effect of the first interface 12 facilitates device insertion and makes the second interface 22 less susceptible to damage from impact.

[0024] In this embodiment, the first inner wall 122 of the first interface 12 is an inclined surface that opens outward from the first interface 12, so that the outer opening size of the first interface 12 is larger than its inner opening size. Therefore, the first interface 12 can be used to insert external devices that are misaligned with the second interface 22, facilitating device insertion. Specifically, the first inner wall 122 of the first interface 12 can be entirely inclined and then connected to the second interface 22 through the inclined surface, or it can be inclined near the outer opening and flat near the inner opening, and then connected to the second interface 22 through the flat surface. The flat surface can better connect with the second interface 22. After the external device is inserted into the second interface 22, it can be electrically connected to the conductive connector 30.

[0025] In this embodiment, at least one of the four inner walls 122 of the first interface 12 is an inclined surface that opens outward from the first interface 12. Specifically, when at least one of the upper and lower inner walls is an inclined surface, it can be used for the insertion of an external device that is vertically offset from the second interface 22; when at least one of the left and right inner walls is an inclined surface, it can be used for the insertion of an external device that is horizontally offset from the second interface 22.

[0026] In this embodiment, the first conductive end 20 includes a guide 24 disposed within the housing 10, and the second interface 22 is opened on the guide 24. The guide 24 also has an interface mounting groove 26 communicating with the second interface 22. One end of the conductive connector 30 is disposed within the interface mounting groove 26, and the second inner wall 222 of the second interface 22 is an inclined surface opening outward from the second interface 22. Specifically, after the external device is inserted, it passes through the first interface 12 and the second interface 22 in sequence, and is inserted into the interface mounting groove 26 to electrically connect with one end of the conductive connector 30. Therefore, by adding the guide 24, the inserted external device can be buffered and guided twice through the second interface 22, thereby further facilitating device insertion and making one end of the conductive connector 30 less susceptible to impact damage. Specifically, the second inner wall 222 of the second interface 22 adopts the same inclined surface design as the first inner wall 122 of the first interface 12. The second inner wall 222 of the second interface 22 can be entirely inclined and then connected to the interface mounting groove 26 through the inclined surface, or it can be inclined near the outer opening and flat near the inner opening and then connected to the interface mounting groove 26 through the flat surface. The flat surface can be connected to the interface mounting groove 26 better.

[0027] Furthermore, the guide member 24 is movable relative to the housing 10, and the conductive connector 30 includes a first conductive plate 32 disposed in the interface mounting groove 26, an elastic conductive plate 34 connected to the first conductive plate 32, and a second conductive plate 36 connected to the elastic conductive plate 34, wherein the second conductive plate 36 is used for fixed installation. In this embodiment, the guide member 24 can move within the housing 10, and the conductive connector 30 also includes a second conductive plate 36 for fixed installation, for example, it can be fixed to an external connection device, and also includes an elastic conductive plate 34 with a certain degree of elasticity. When the guide 24 is in its initial position, its second interface 22 is connected to the first interface 12 by the support of the elastic conductive plate 34. When an external device with a positional deviation from the first interface 12 is inserted, it first undergoes initial buffering and guidance through the first interface 12. Then, the external device slides to the second interface 22, where it undergoes a second round of buffering and guidance. At this point, the external device still impacts the second interface 22 in the direction of its positional deviation, causing the elastic conductive plate 34 to deform and the guide 24 to move in the direction of its positional deviation, thus providing better buffering against the impact of the external device. Therefore, when the external device slides into the interface mounting slot 26, most of the impact force has been buffered, preventing damage to the conductive structure within the interface mounting slot 26.

[0028] In another embodiment, the guide member 24 is movable relative to the housing 10. The conductive connector 30 includes a first conductive plate 32 disposed at the second interface 22, an elastic conductive plate 34 connected to the first conductive plate 32, and a second conductive plate 36 connected to the elastic conductive plate 34. The second conductive plate 36 is used for fixed installation. Specifically, this solution eliminates the need for secondary buffering and guiding at the second interface 22 of the guide member 24. The first conductive plate 32 is disposed within the second interface 22, directly buffering the impact of external devices through the movable first conductive end 20 and the elastic conductive plate 34. The first conductive end 20 includes the guide member 24 disposed within the housing 10, and the second interface 22 is opened at the guide member 24.

[0029] Furthermore, the elastic conductive plate 34 is wavy in the insertion direction of the first interface 12. In this embodiment, the elastic conductive plate 34 is made of a conductive material that can elastically deform, such as copper or aluminum. It can be used to generate deformation perpendicular to the insertion direction of the first interface 12, such as deformation in the horizontal or vertical direction, thereby protecting the conductive structure located in the horizontal or vertical direction within the interface mounting groove 26. The wavy shape of the elastic conductive plate 34 also allows it to deform in the insertion direction of the first interface 12, thus buffering against impacts from external devices. In other embodiments, the elastic conductive plate 34 can also be serrated or spiral in the insertion direction of the first interface 12.

[0030] Furthermore, the guide member 24 has a guide protrusion 242 on its side, and the inner wall of the housing 10 has a matching guide groove 14. The depth of the guide groove 14 in the vertical direction of the insertion direction of the first interface 12 is greater than the length of the guide protrusion 242. In this embodiment, when the guide member 24 can move within the housing 10, the movement of the guide member 24 is guided and limited by adding a guide protrusion 242 on the side of the guide member 24 and providing a guide groove 14 on the inner wall of the housing 10. Specifically, the vertical direction of the insertion direction of the first interface 12 includes both horizontal and vertical directions, that is, the depth of the guide groove 14 is greater than the length of the guide protrusion 242 in either the horizontal or vertical direction, thereby providing guidance and limitation in either the horizontal or vertical direction. The guide protrusions 242 can be respectively located on the top and bottom edges of the guide member 24, or on the left and right sides of the guide member 24, or along the edge of the outer wall of the second interface 22, and are distributed in a ring.

[0031] Furthermore, both the first conductive plate 32 and the second conductive plate 36 are rigid copper busbars, while the elastic conductive plate 34 is a flexible copper busbar. In this embodiment, the first plate body of the first conductive plate 32 and the second plate body of the second conductive plate 36 are rigid copper busbars, which serve a fixing function, while the flexible copper busbar serves to buffer the impact force. The flexible copper busbar is formed by stacking several copper sheets, thus possessing both conductive and elastic deformation properties. Then, the two ends of the flexible copper busbar are respectively welded to the two ends of the rigid copper busbar.

[0032] Please refer to Figure 4 and Figure 5 In this embodiment, the first conductive plate 32 includes a first plate body 322 disposed within the interface mounting groove 26 and a fixing plate 324. The first plate body 322 has a first conductive sheet 326. The fixing plate 324 has a perforated groove 3242 that matches the position of the first conductive sheet 326. The fixing plate 324 presses down on the first conductive sheet 326 and fixes it to the first plate body 322. Specifically, the inner sidewall of the interface mounting groove 26 has a slot 262. The first conductive plate 32 is inserted into the slot 262, allowing the position of the first conductive sheet 326 to be electrically connected to the external device inserted into the interface mounting groove 26. In another embodiment, two conductive connectors 30 are provided, and two or four corresponding slots 262 are also provided, allowing the first conductive sheets 326 of the two first plates 322 to clamp the inserted device in a vertical or horizontal direction to achieve electrical connection. The first conductive sheet 326 is fixed to the first plate 322 by the fixing plate 324, thereby ensuring the installation stability of the first conductive sheet 326 and making it difficult to move or fall off even after being impacted.

[0033] Furthermore, the first conductive sheet 326 includes a connecting portion 3262 disposed on the first plate 322, and a plurality of arc-shaped conductive portions 3264 disposed on the connecting portion 3262. The plurality of conductive portions 3264 are spaced apart. After the fixing plate 324 presses down on the connecting portion 3262, it is fixed to the first plate 322. The conductive portions 3264 are exposed in the hollow groove 3242. Specifically, the arc-shaped conductive portions 3264 can provide a certain buffer for inserted external devices, thereby reducing the possibility of damage. The spaced-apart arrangement of the plurality of conductive portions 3264 allows the fixing plate 324 to press down on the connecting portion 3262 between the conductive portions 3264, and then fix it to the first plate 322 by screws.

[0034] Furthermore, the connecting portion 3262 has a gap 3266 formed in the direction perpendicular to the insertion direction of the first interface 12, and the two ends of the conductive portion 3264 are respectively located on both sides of the gap. In this embodiment, the separate connecting portions 3262 are connected through the two ends of the conductive portion 3264, so the separate connecting portions 3262 have a certain elasticity. When the conductive portion 3264 is impacted, the separate connecting portions 3262 can deform, thereby providing a certain buffer and preventing damage to the conductive portion 3264.

[0035] In this embodiment, the width of the second interface 22 in the vertical direction matches the part to be inserted, and the width of the second interface 22 in the horizontal direction is slightly larger than the part to be inserted. Specifically, when the first inner wall 122 of the first interface 12 is an inclined surface that opens outward from the first interface 12, the outer opening size of the first interface 12 is larger than its inner opening size, and the width of its inner opening in the vertical direction matches the part to be inserted, while the width in the horizontal direction is slightly larger than the part to be inserted. After the part to be inserted is inserted, the part to be inserted contacts the conductive structure in the vertical direction and is relatively fixed, while the part to be inserted can move to a certain extent in the horizontal direction without affecting the contact with the conductive structure in the vertical direction.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
