However, the flexibility, stretchability, conductivity, and poor heat resistance of elastic conductors impose significant limitations on their processing. Current technology uses soldering to connect the elastic conductors to connectors for signal transmission; however, using heat-based soldering to connect the conductors and connectors can easily damage the elastic conductors, causing considerable processing difficulties.

[0004] To address the aforementioned technical problems, this utility model provides a connecting device for connecting an elastic conductor assembly. The elastic conductor assembly comprises multiple elastic conductors. The connecting device includes: a fixed base, the fixed base comprising two crossbars and a lifting structure, the two crossbars being spaced apart, and the lifting structure being disposed between the two crossbars. A through hole is formed between the lifting structure and each of the two crossbars, allowing the elastic conductor assembly to pass through. This allows the elastic conductor assembly to pass through the bottom sides of the two crossbars and the top side of the lifting structure, resulting in the elastic conductor assembly being bent and inserted into the space. The device includes a mounting base; a circuit board having multiple first contacts and multiple second contacts on opposite sides; and a connector having multiple pins, with the multiple first contacts soldered to the multiple pins of the connector, the circuit board being mounted on the mounting base; wherein the multiple elastic wires are liftable by the lifting structure, so that each of the multiple elastic wires forms a protrusion, and the protrusions of the multiple elastic wires contact the multiple second contacts of the circuit board, so that the multiple elastic wires are electrically connected to the connector through the circuit board.
[0005] Optionally, the fixing base further includes two side rods, which are spaced apart. The two ends of the two crossbars are respectively connected to the two ends of the two side rods, and the two ends of the lifting structure are respectively connected to the two side rods.
[0006] Optionally, the lifting structure is located at the middle bottom side of the fixed base, and the lifting structure is equidistant from the two crossbars.

[0008] Optionally, the two crossbars and the lifting structure are located at different horizontal heights, with the horizontal height of the two crossbars being higher than that of the lifting structure, and the lifting structure being located on the bottom side of the fixed base.
[0009] Optionally, the two crossbars are provided with a plurality of first grooves spaced apart, and the lifting structure is provided with a plurality of second grooves spaced apart. The plurality of first grooves are respectively provided on the bottom side of the two crossbars, and the plurality of second grooves are provided on the top side of the lifting structure. The plurality of elastic wires are respectively accommodated in the plurality of first grooves and the plurality of second grooves.
[0010] Optionally, conductive adhesive is disposed between the plurality of elastic wires and the plurality of second contacts.

[0013] Optionally, the circuit board is pressed onto the protrusions of the plurality of elastic wires, such that the protrusions of the plurality of elastic wires are respectively in tight contact with the second contact of the circuit board.
[0014] The beneficial effects of this utility model are as follows: the connecting device provided by this utility model includes a fixed base, a circuit board, and a connector. The fixed base includes two crossbars and a lifting structure. The lifting structure is disposed between the two crossbars, and a through hole is formed between the lifting structure and the two crossbars for the elastic wire assembly to pass through. The elastic wire assembly can pass through the bottom side of the two crossbars and the top side of the lifting structure, so that the elastic wire assembly is bent and passed through the fixed base. The opposite sides of the circuit board are respectively provided with multiple first contacts and multiple second contacts.

The protrusions of the multiple elastic wires contact the multiple second contacts of the circuit board, so that the multiple elastic wires are electrically connected to the connector through the circuit board. This invention utilizes the friction of elastic wires passing through a fixing base to secure them together. This increases friction, and the structure of the fixing base allows the path of the elastic wires to bend, further increasing friction and preventing them from falling off. The fixing base and circuit board can clamp the elastic wires together. The expansion force of the multiple elastic wires after compression further ensures they adhere firmly to the circuit board and conduct electricity.

[0024] [Example]
[0025] Please see Figures 1 to 3 This utility model provides a connecting device for connecting an elastic wire assembly 100. The elastic wire assembly 100 includes multiple elastic wires 101, which are formed by spirally winding spun yarn and metal wire, thus possessing softness, elasticity, and conductivity. The multiple elastic wires 101 can also be connected to an adhesive backing 102. The number of elastic wires 101 is not limited; this embodiment illustrates a connection method using six elastic wires 101 and an adhesive backing 102 patch. This utility model can be applied to both ends of the elastic wire assembly 100 (e.g., ...). Figure 8 As shown in the figure, the connecting device includes a fixed base 1, a circuit board 2 and a connector 3.
[0026] Please see Figure 4 and Figure 5 As shown, the fixing base 1 can be made of insulating materials such as plastic. The fixing base 1 includes two crossbars 12 and a lifting structure 13. The two crossbars 12 are spaced apart, and the lifting structure 13 is disposed between the two crossbars 12. The lifting structure 13 and the two crossbars 12 are spaced apart, and the two crossbars 12 and the lifting structure 13 can be parallel to each other. Alternatively, two side bars 11 can be disposed between the two crossbars 12. The two side bars 11 are spaced apart and can be parallel to each other. The two ends of the two crossbars 12 can be respectively connected to the two ends of the side bars 11, so that the two side bars 11 and the two crossbars 12 can form a frame. The two ends of the lifting structure 13 can be respectively connected to the two side bars 11, so that the structure of the fixing base 1 can be more stable.
[0027] A through hole 14 is formed between the lifting structure 13 and each of the two crossbars 12, through which the elastic wire assembly 100 can pass. The lifting structure 13 can be located at the middle bottom side of the fixed base 1, and the lifting structure 13 can be equidistant from the two crossbars 12, so that the lifting structure 13 is located in the middle of the two crossbars 12, thus having an optional lifting effect. The flexible wire assembly 100 can pass through the two crossbars 12 and the lifting structure 13 on opposite sides. That is, the flexible wire assembly 100 can pass through the bottom side of the two crossbars 12 and the top side of the lifting structure 13, allowing it to be bent and inserted into the fixing base 1. This effectively increases the friction between the flexible wire assembly 100 and the fixing base 1, and the lifting structure 13 provides a lifting effect for the flexible wires 101. Each of the multiple flexible wires 101 can be lifted by the lifting structure 13 to form an upwardly protruding protrusion 1011, which can then contact the circuit board 2. Optionally, the protrusion 1011 is elongated, with a length greater than the diameter of the flexible wire 101, thus providing a larger contact area and improving conductivity. The adhesive 102 can also be removed from the portion of the flexible wire assembly 100 corresponding to the lifting structure 13, allowing the lifting structure 13 to directly contact the flexible wires 101 and further enhancing the lifting effect. If the adhesive 102 is not removed, it can still have the effect of lifting the elastic conductor 101 (e.g. Figure 3 (As shown).
[0028] Please see Figures 3 to 5 As shown, in this embodiment, the two crossbars 12 and the lifting structure 13 are located at different horizontal heights. The horizontal height of the two crossbars 12 is higher than the horizontal height of the lifting structure 13. The lifting structure 13 is located on the bottom side of the fixed base 1 and has a height H, thereby having the effect of lifting the elastic conductor assembly 100 upward, so that the multiple elastic conductors 101 can protrude to a predetermined height.
[0029] In this embodiment, multiple first grooves 121 are spaced apart on the two crossbars 12, and multiple second grooves 131 are spaced apart on the lifting structure 13. The first grooves 121 and second grooves 131 are respectively located on opposite sides of the crossbars 12 and the lifting structure 13. The first grooves 121 are located on the bottom side of the crossbars 12, and the second grooves 131 are located on the top side of the lifting structure 13. The multiple elastic conductors 101 are respectively accommodated in the multiple first grooves 121 and the multiple second grooves 131, so that the multiple elastic conductors 101 can have a better positioning effect when passing through the opposite sides of the two crossbars 12 and the lifting structure 13. However, the positioning method of the multiple elastic conductors 101 is not limited. For example, other spaced structures can also be used for spaced positioning.
[0030] The circuit board 2 can be a flexible printed circuit board (FPC), and it is flexible. The connector 3 is soldered to the circuit board 2. The circuit board 2 can act as an adapter board, allowing the wiring of the connector 3 to be adjusted to match the spacing of the multiple elastic wires 101 via the wiring on the circuit board 2. Please refer to [link / reference]. Figure 6 and Figure 7 As shown, the circuit board 2 has multiple first contacts 21 and multiple second contacts 22 on opposite sides. The multiple first contacts 21 and multiple second contacts 22 are metal contacts. The connector 3 has multiple pins 31. The multiple first contacts 21 can be soldered to the multiple pins 31 of the connector 3, fixing the connector 3 to the circuit board 2, and achieving an electrical connection between the circuit board 2 and the connector 3. The connection device of this invention allows the connector 3 and the circuit board 2 to be connected using a thermal process before connecting the elastic wire 101, avoiding interference with the subsequent assembly of the elastic wire 101. Therefore, a thermal process is not required to connect the elastic wire 101 and the connector 3.
[0031] This invention assembles a fixed base 1 and an elastic wire assembly 100, fixing them together through the friction of the elastic wire assembly 100 passing through the fixed base 1. A lifting structure 13 is provided at the bottom center of the fixed base 1, which can push the elastic wire assembly 100 upwards (e.g., ...). Figure 3 As shown), the lifting structure 13 can provide contact force, that is, it can provide positive force to the elastic conductor assembly 100.
[0032] The circuit board 2 is mounted on the mounting base 1. The surfaces of the multiple elastic wires 101 are coated with insulating varnish, which can be removed by laser to expose the conductors 1012 (such as...) inside the elastic wires 101. Figure 7 As shown, the wires are exposed and then assembled with circuit board 2. Circuit board 2 has multiple second contacts 22 that correspond to the multiple elastic wires 101. Circuit board 2 is pressed onto the protrusions 1011 of the multiple elastic wires 101. The height of the protrusions 1011 of the multiple elastic wires 101 is used to press them tightly into contact with the multiple second contacts 22 of circuit board 2. Reliable contact can be achieved by using the contact between the protrusions 1011 of the elastic wires 101 and the second contacts 22 of circuit board 2. The fixing base 1 and circuit board 2 can clamp the elastic wire assembly 100. In addition, conductive adhesive 24 (such as...) can be provided between the multiple elastic wires 101 and the multiple second contacts 22. Figure 7 (As shown), it is used to increase the conductivity.
[0033] In this embodiment, the mounting base 1 has multiple positioning posts 15, and the circuit board 2 has multiple positioning holes 23. The multiple positioning posts 15 respectively cooperate with the multiple positioning holes 23, so that the mounting base 1 and the circuit board 2 have good positioning. In addition, the multiple positioning posts 15 on the top of the circuit board 2 can be flattened by hot pressing, and the excess elastic wires 101 on the side of the mounting base 1 can be cut off, and the covering body 16 (such as...) can be set by dispensing. Figure 8 (As shown) The sheath 16 is provided on the fixing base 1 for insulation and fixation, and can provide the functions of fixing and insulating the flexible wire 101.

The lifting structure is disposed between the two crossbars, and a through hole is formed between the lifting structure and each of the two crossbars, allowing the elastic wire assembly to pass through. The elastic wire assembly can pass through the bottom side of the two crossbars and the top side of the lifting structure, so that the elastic wire assembly is bent and passed through the fixed base. The opposite sides of the circuit board are respectively provided with multiple first contacts and multiple second contacts.
