Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically, to a floating connector. Background Technology

[0002] Connectors are frequently used in circuit connections, and multiple connectors are often used on a circuit board. Traditional floating connectors are mostly rigid connectors, which require precise alignment during mating to avoid installation errors, making installation difficult. Utility Model Content

[0003] The problem solved by this invention is how to provide a floating connector that can adjust the docking position during the docking process and reduce the impact of installation errors on the connection.

[0004] To address the aforementioned problems, this utility model provides a floating connector, comprising: an outer shell, an inner shell, a mating seat, mating components, a floating device, and a substrate connecting piece. The inner shell is located inside the outer shell, and the mating seat is located inside the inner shell. The bottom of the mating seat is connected to the bottom of the inner shell. Multiple mating components are evenly spaced and fixed to both sides of the mating seat. The floating device includes multiple elastic components, the number of which is the same as the number of mating components. The inner end of each elastic component is connected to the bottom of the corresponding mating component, and the outer end is connected to the corresponding substrate connecting piece. The bottom of the inner shell rests on the floating device to enable the inner shell and the mating seat to float during mating.

[0005] Furthermore, the elastic component includes a U-shaped spring sheet and an elastic connecting piece. The U-shaped spring sheet is inverted U-shaped. The bottom of the inner side of the U-shaped spring sheet is connected to the first end of the elastic connecting piece, and the second end of the elastic connecting piece is connected to the bottom of the mating component. The outer side of the U-shaped spring sheet is fixed to the outer shell. The inner end of the substrate connecting piece is connected to the outer side of the U-shaped spring sheet. The substrate connecting piece passes through the bottom of the outer shell and its outer end is located outside the outer shell.

[0006] Furthermore, the inner side of the U-shaped elastic piece is shorter than the outer side, so that when the substrate connecting piece is fixed on the circuit board, there is a first floating space between the bottom surface of the elastic connecting piece and the circuit board, and the bottom of the inner shell is placed on the top surface of the elastic connecting piece.

[0007] Furthermore, there is a gap between the inner side of the U-shaped spring and the outer side of the inner shell.

[0008] Furthermore, the docking seat has a T-shaped cross-section, including a top docking plate and a fixing plate perpendicular to the docking plate. The top of the fixing plate is fixed to the center of the bottom surface of the top docking plate, and the bottom is fixed to the bottom of the inner shell.

[0009] Furthermore, the docking component is fixed to both sides of the fixing plate. The top of the docking component has an arc-shaped elastic protrusion, and the bottom extends downward along the fixing plate through the bottom surface of the inner shell and connects with the elastic connecting piece.

[0010] Furthermore, the sides of the inner shell and the docking top plate extend downwards to form guide portions.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The floating device of this connector includes elastic components that are connected one-to-one with multiple mating parts and substrate connecting pieces. When this connector is installed on the circuit board, the multiple elastic components and the floating space formed between them, the circuit board, and the housing allow the inner housing and mating seat to float. This allows for a certain positional deviation in the X, Y, and Z directions when the connector is connected to the connector, reducing the impact of installation errors on the connection.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0017] like Figure 1 As shown, this utility model provides a floating connector, including: an outer shell 1, an inner shell 2, a mating seat 3, mating components 5, a floating device, and a substrate connecting piece 6. The inner shell 2 is located inside the outer shell 1, and the mating seat 3 is located inside the inner shell 2. The bottom of the mating seat 3 is connected to the bottom of the inner shell 2. Multiple mating components 5 are evenly spaced and fixed to both sides of the mating seat 3. The floating device includes multiple elastic components 4, and the number of elastic components 4 and substrate connecting pieces 6 is the same as the number of mating components 5. In use, as... Figure 2 As shown, the bottom of the floating connector is fixed to the circuit board 8 by the substrate connecting piece 6, and the plug 9 is inserted from above. The plug 9 matches the floating connector. The plug 9 has contact pieces that are spaced apart from the mating part 5 to make one-to-one connection of the connection points. Due to the floating device, when the connector is mated, there is a certain positional deviation in the X, Y and Z directions, which reduces the impact of installation error on the connection.

[0018] In this embodiment, the outer shell 1, inner shell 2, and mating seat 3 can be made of insulating plastic material, while the mating component 5, elastic component 4, and substrate connecting piece 6 are all made of elastic metal material. The spacing between the substrate connecting pieces 6 is 0.8mm. The 0.8mm pin spacing allows the connector to provide more signal channels in a limited space, making it suitable for high-density circuit board designs.

[0019] The elastic component 4 includes a U-shaped spring sheet 41 and an elastic connecting piece 42. The U-shaped spring sheet 41 is inverted U-shaped. The bottom of the inner side of the U-shaped spring sheet 41 is connected to the first end of the elastic connecting piece 42. The second end of the elastic connecting piece 42 is connected to the bottom of the docking component 5. The outer side of the U-shaped spring sheet 41 is fixed on the outer shell 1. The inner end of the substrate connecting piece 6 is connected to the outer side of the U-shaped spring sheet 41. The substrate connecting piece 6 passes through the bottom of the outer shell 1, and its outer end is located outside the outer shell 1.

[0020] Because there are gaps between the elastic components 4, a Z-axis floating space is formed, allowing the inner shell 2 and the docking seat 3 to float longitudinally in the plane.

[0021] In one embodiment of the present invention, the inner side of the U-shaped spring sheet 41 is shorter than the outer side, such that when the substrate connecting piece 6 is fixed on the circuit substrate 8, there is a first floating space between the bottom surface of the elastic connecting piece 42 and the circuit substrate 8, and the bottom of the inner shell 2 is placed on the top surface of the elastic connecting piece 42.

[0022] like Figure 2 As shown, the first floating space is the vertical Y-axis floating space. During installation, if floating is required for easy docking, the inner shell 2 can be pushed downwards, the U-shaped spring 41 will deform, and the inner shell 2 and the docking seat 3 connected to it can move downwards. Once docking is completed, the external force disappears, and it returns to its position under the elastic force of the U-shaped spring 41. Figure 2 In the middle, the inner shell 2 is divided into two staggered upper and lower parts, and the connection between the upper and lower parts forms an annular platform for contacting the bottom of the support plug 9.

[0023] In one embodiment of this utility model, there is a gap between the inner side of the U-shaped spring sheet 41 and the outer side of the inner shell 2.

[0024] It should be noted that, as Figure 2 As shown, since the outer side of the U-shaped spring 41 is fixed to the outer shell 1, there is a gap between the inner side of the U-shaped spring 41 and the inner side of the outer shell 1 and the outer side of the inner shell 2. As the floating space of the X-axis, the U-shaped spring 41 bends and deforms left and right, and the inner shell 2 and the docking seat 3 can float laterally in the plane accordingly.

[0025] In one embodiment of this utility model, the docking seat 3 has a T-shaped cross-section, including a top docking plate and a fixing plate perpendicular to the docking plate. The top of the fixing plate is fixed to the center of the bottom surface of the top docking plate, and the bottom is fixed to the bottom of the inner shell 2. The docking component 5 is fixed to both sides of the fixing plate. The top of the docking component 5 has an arc-shaped elastic protrusion, and the bottom passes down through the bottom surface of the inner shell 2 along the fixing plate and is connected to the elastic connecting piece 42.

[0026] It should be noted that the bottom of the fixing plate of the docking seat 3 is fixed to the bottom of the inner shell 2, and the bottom of the docking component 5 is connected to the elastic connecting piece 42 through the bottom surface of the inner shell 2, so that the docking seat 3 is fixed to the bottom of the inner shell 2 and can float together with the elastic connecting piece 42. The top of the docking component 5 has an arc-shaped elastic protrusion. When the plug 9 is inserted, the elastic protrusion can press the corresponding contact piece on the plug 9 to ensure the transmission of electrical signals.

[0027] In one embodiment of the present invention, the inner shell 2 and the side of the docking top plate extend downward to form a guide portion 7.

[0028] It should be noted that during docking, the inclined guide 7 can guide the plug 9 to be inserted between the inner housing 2 and the docking seat 3 to complete the docking.

[0029] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
