[ detailed description ] embodiments

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

In the present disclosure, "a" or "an" is used to describe the units, elements and components described herein. This is done for convenience of illustration only and to provide a general sense of the scope of the invention. Thus, unless clearly indicated to the contrary, such description should be read to include one, at least one and the singular also includes the plural.

In the present disclosure, the terms "comprise," "include," "have," "contain," or any other similar terms are intended to cover non-exclusive inclusions. For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".

Fig. 1 is a schematic structural diagram of a floating bus connection assembly according to a first embodiment of the present invention. In fig. 1, the floating bus connecting 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 be referred to in fig. 5.

Returning to fig. 1, floating bus connection assembly 10 includes a connecting portion 12 and a coupling portion 14. It should be noted that, in the present embodiment, the connection portion 12 and the combining portion 14 are implemented as separate components, and in another embodiment, the connection portion 12 and the combining portion 14 may be implemented as an integral component.

The connecting portion 12 includes a frame 121, a plate 122 and an elastic member 126. In the present embodiment, the frame body 121, the plate body 122 and the elastic member 126 may be cut from the plate body 122 by laser engraving, CNC processing, and the like.

The frame 121 surrounds the plate 122 and the elastic body 126. In the present embodiment, the shape of the frame 121 is illustrated 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 and the central portion are taken as an example for explanation, and the adjustment can be made according to the actual application.

The plate 122 is connected to the frame 121 by an elastic member 126. The shape of the plate 122 is illustrated by an inverted T-shaped structure, and other embodiments are not limited to the T-shaped structure, as 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 board 122 is defined as a T-shaped cover 124, and the T-shaped cover 124 forms a second receiving space SP for disposing the connecting portion 14. In the present embodiment, the T-shaped cover 124 is formed at the central portion of the plate 122 to correspond to the position of the T-shaped retaining groove 128. In other embodiments, the adjustment may be performed according to actual application, and the T-shaped spacing groove 128 may not only be provided correspondingly, but also be offset. In addition, the number of the elastic members 126, such as a spring, a spring plate, an elastic arm, etc., may be less than or more than 4 in other embodiments besides 4 in this embodiment. In addition, the elastic member 126 in this embodiment is an S-shaped structure for generating an elastic force.

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

Further, openings 1242 are provided on both sides of the T-shaped cover 124, respectively, so that the first flexible flat cable 22 and the second flexible flat cable 44 can be inserted therein, respectively.

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 connecting element 142 is illustrated 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 separately, and refer to fig. 5. Furthermore, the stopper 146 is disposed between the first connecting member 142 and the limiting member 144. In addition, the outer edge of the stop member 146 is greater than or equal to the outer edge of the T-shaped retaining groove 128.

It should be noted that the shape or size of the limiting element 144 and the shape or size of the T-shaped limiting groove 128 determine the moving direction of the combining portion 14 in the second accommodating space SP; and the stop piece 146 and the T-shaped limiting groove 128 determine the moving depth of the combining portion 14 in the first accommodating space.

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

For example, when the connecting portion 12 is connected to the connecting portion 14, the first connecting member 142 is disposed in the second receiving space SP and the limiting member 144 is received in the first receiving space. When an external force is applied to actuate 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, during the movement of the limiting element 144, when the stopping element 146 contacts the T-shaped limiting groove 128 corresponding to the first accommodating space, the limiting element 144 is limited to move only within a range, for example, the moving range refers to a gap d between the T-shaped cover 124 and the T-shaped limiting groove 128. In particular, when the size of the limiting member 144 is close to the inner edge of the first accommodating space, the moving range is limited to the XY plane, for example.

It is noted that the floating bus connection assembly 10 may further include a latch 1210 formed on the connecting portion 12 to secure the connecting portion 12 to, for example, the sheet metal member 8 of fig. 5.

Referring also to fig. 4, the main board 6 of the floating bus connection assembly 10 further includes a second connector 16 connected to the first connector 142. In this embodiment, the second connector 16 is illustrated as a female terminal, and in other embodiments, the second connector 16 may also be a male terminal. In another embodiment, and referring to fig. 4 for an enlarged view of the second connecting member 16, the second connecting member is configured to have a shape with an upper width larger than a lower width, and is shaped like a funnel or a bell mouth, so that the first connecting member 142 slides into the second connecting member 16 to be coupled.

Although the present invention has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form, construction, features, methods and quantities may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
