[ Detailed description ] of the invention

For a thorough understanding of the objects, features and effects of the present invention, reference will be made to the following detailed description of the invention taken in conjunction with the accompanying drawings.

In the present disclosure, units, elements, and components described herein are described using "a" or "an". This is for convenience of description only and is not intended to provide a general sense of the scope of the invention. Thus, unless expressly stated otherwise, such description should be construed as including one, at least one, and the singular also includes the plural.

In the present invention, the terms "comprising," "including," "having," "containing," or any other similar language are intended to cover non-exclusive inclusion. For example, a component, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements listed herein, but may include other elements not expressly listed but inherent to such component, structure, article, or apparatus. In addition, unless explicitly stated to the contrary, the term "or" refers to an inclusive "or" and not to an exclusive "or".

Referring to fig. 1, a schematic structure of a floating bus connection assembly according to a first embodiment of the present invention is shown. In fig. 1, the floating bus connection assembly 10 connects a first circuit board 2 having a first flexible flat cable 22, a second circuit board 4 having a second flexible flat cable 44, and a motherboard 6, and the first circuit board 2, the second circuit board 4, and the motherboard 6 can refer to fig. 5.

Returning to fig. 1, the floating bus connection assembly 10 includes a connection portion 12 and a coupling portion 14. It should be noted that, in the present embodiment, the connection portion 12 and the connection portion 14 are separate components, and in another embodiment, the connection portion 12 and the connection portion 14 may be integrally formed.

The connecting portion 12 includes a frame 121, a plate 122 and an elastic member 126. In the present embodiment, the frame 121, the plate 122 and the elastic member 126 may be cut from the plate 122 by Lei Diao, CNC machining, etc.

The frame 121 surrounds the plate 122 and the elastic member 126. In the present embodiment, the shape of the frame 121 is described as a rectangle, and in other embodiments, the shape of the frame 121 may be a square or other shapes. The frame 121 may be made of metal or nonmetal.

Furthermore, a T-shaped limiting groove 128 is formed at the edge of the frame 121, and the T-shaped limiting groove 128 forms a first accommodating space. In the present embodiment, the inner edge of the short side of the frame 121 is described as the center, and the adjustment can be made depending on the actual application.

The plate 122 is connected to the frame 121 via an elastic member 126. The shape of the plate 122 is illustrated as an inverted T-shaped structure, and other embodiments are not limited to the T-shaped structure, so long as the plate 122 can form a receiving space of the combination joint 14, which falls within the scope of the present invention. In the present embodiment, the protruding portion of the plate 122 is defined as a T-shaped cover 124, and the T-shaped cover 124 forms a second accommodating space SP for disposing the bonding portion 14. In the present embodiment, the T-shaped cover 124 is formed at a central portion of the plate 122 to correspond to the position of the T-shaped limiting slot 128. In other embodiments, the adjustment may be performed according to the actual application, and the adjustment may be not necessarily performed corresponding to the T-shaped limiting groove 128, but may be offset. In addition, the number of the elastic members 126, such as springs, elastic sheets, elastic arms, etc., may be less than or more than 4 in other embodiments, in addition to 4 in the present embodiment. In addition, the elastic member 126 in the present embodiment has an S-shaped structure for generating an elastic force.

In this embodiment, the edge of the frame 121 is bent at an angle to strengthen the strength of the connecting portion 12.

Furthermore, openings 1242 are formed on the two sides of the T-shaped cover 124, so that the first flexible flat cable 22 and the second flexible flat cable 44 can be inserted into each other.

The combining portion 14 includes a first connecting member 142, a limiting member 144 and a stopping member 146. The limiting member 144 and the stopping member 146 are respectively disposed at two ends of the first connecting member 142, and the limiting member 144 and the stopping member 146 are connected to the first connecting member 142. In the present embodiment, the first connector 142 is described as a male terminal, and in other embodiments, the male terminal may be replaced by a female terminal. The first connector 142 can connect the first flexible flat cable 22 and the second flexible flat cable 44, respectively, and fig. 5 is also referred to. Furthermore, a stop 146 is disposed between the first connector 142 and the stop 144. In addition, the outer edge of the stopper 146 is greater than or equal to the outer edge of the T-shaped limit groove 128.

It should be noted that, the shape or size of the limiting member 144 and the shape or size of the T-shaped limiting slot 128 determine the moving direction of the connecting portion 14 in the second accommodating space SP; and, the stopper 146 and the T-shaped limiting groove 128 determine the moving depth of the coupling portion 14 in the first accommodating space.

When the connecting portion 12 engages the engaging portion 14, reference is made to fig. 2 and 3, and fig. 2 is a schematic side view illustrating the connecting portion engaging portion of fig. 1 according to the present invention; and, fig. 3 is a schematic plan view illustrating the connecting portion joining and coupling portion of fig. 1 according to the present invention. The first connecting piece 142 is disposed in the second accommodating space SP and the limiting piece 144 is disposed in the first accommodating space. According to an external force (not shown), the plate 122 is restricted by the stopper 144, the stopper 146 and the T-shaped stopper groove 128 to move on the XY plane.

For example, when the connecting portion 12 engages the coupling portion 14, the first connecting member 142 is disposed in the second accommodating space SP and the limiting member 144 is accommodated in the first accommodating space. When an external force is applied to urge the plate 122, the plate 122 is acted by the elastic member 126, so that the limiting member 144 moves in the first accommodating space. In addition, when the stopper 146 touches the T-shaped limiting groove 128 corresponding to the first accommodating space during the movement of the limiting member 144, the limiting member 144 is limited to move only within a range, for example, the moving range refers to the gap d between the T-shaped cover 124 and the T-shaped limiting groove 128. In particular, when the size of the stopper 144 approaches the inner edge of the first accommodating space, the moving range will be limited to, for example, the XY plane.

It should be noted that the floating bus connection assembly 10 may further include a fastener 1210 formed on the connection portion 12 to enable the connection portion 12 to be fixed to the sheet metal member 8 of fig. 5, for example.

Referring to fig. 4 together, the motherboard 6 of the floating bus connector assembly 10 further includes a second connector 16 connected to the first connector 142. In the present embodiment, the second connector 16 is described as a female terminal, and in other embodiments, the second connector 16 may be a male terminal. In another embodiment, referring to fig. 4, the second connecting member 16 is configured to have a shape with an upper width larger than a lower width, like a funnel or a bell mouth, so that the first connecting member 142 slides into the second connecting member 16 to be combined.

Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited to the details of the shape, construction, features, methods and the number of the embodiments described in the claims can be modified somewhat without departing from the spirit and scope of the present invention.
