[0002] The spinning lead is made of spinning thread and metal lead wound in a spiral manner, and has the characteristics of being retractable and conductive. If the spinning lead is applied to fabric, it can transmit signals from various parts of the body to the device center for processing without losing the retractable characteristics of the fabric, so it can be applied to products such as functional clothing. Generally, the connection between different carriers of electrical signals is achieved through welding, adding a metal medium between the conductors to transmit the electrical signal, but the spinning thread itself is not resistant to high temperatures. When there is a need to transmit electrical signals, it is necessary to develop a new and fast connection method. Utility Model Content

[0022] See also Figure 1 The utility model provides a quick connection structure of a lead wire and a connecting terminal, comprising at least one lead wire 1, at least one fork-shaped terminal 2 and at least one connecting terminal 3.

[0023] The lead wire 1 can be selected as an extremely fine wire, such as an American Wire Gauge (AWG) standard of 40 or above. The lead wire can also be a spinning lead wire. The spinning lead wire includes a spinning wire and a metal lead wire (not shown), which are wound in a spiral manner. The spinning lead wire is a retractable and conductive spinning lead wire structure, and has the characteristics of being retractable and conductive. Since the spinning lead wire is a prior art, and the present invention does not limit the structure of the lead wire 1, it will not be described in detail. The number of the lead wires 1 is not limited. One or more lead wires 1 can be provided. The present embodiment discloses that multiple lead wires 1 are provided, and have a larger transmission capacity. Multiple lead wires 1 are combined together, and two lead wires 1 can be assembled together in the same mounting hole 32.

[0024] The fork-shaped terminal 2 is generally in the shape of a harpoon, and has a fork portion 21 at one end. The fork portion 21 is forked, and a receiving space 22 is formed in the fork portion 21 to accommodate the lead 1. Optionally, the width of the receiving space 22 gradually decreases inwardly, so that the lead 1 can be gradually clamped when placed in the receiving space 22, thereby having an optional fixing and conducting effect.

[0025] The fork portion 21 can be connected to a material strip 23, and a breaking line 24 can be provided between the fork portion 21 and the material strip 23. The fork-shaped terminal 2 is connected to the material strip 23 so that the fork-shaped terminal 2 can be driven to be assembled to the connecting terminal 3 by the material strip 23. After the fork portion 21 of the fork-shaped terminal 2 and the lead 1 are pressed into the mounting hole 32 of the connecting terminal 3, the fork portion 21 and the material strip 23 can be broken and separated by the breaking line 24.

[0026] The end of the fork 21 away from the material strip 23 may form a guide portion 25, the width W1 of the guide portion 25 is smaller than the width W2 of the fork 21, and the guide portion 25 is rounded, which can provide an optional guiding effect, so that the fork 21 of the fork-shaped terminal 2 can be smoothly inserted into the mounting hole 32. A plurality of fork-shaped terminals 2 can be connected to each material strip 23, so that a plurality of leads 1 can be installed in the mounting holes 32 of a plurality of connection terminals 3 at one time by using a plurality of fork-shaped terminals 2, which is feasible for mass production, and the number of single installations can also be adjusted according to the number of connection terminals 3.

[0027] The connecting terminal 3 may be a connector 100 (eg Figure 1 and Figure 2 The connector 100 is an electrical connector. The connector 100 includes a connector body 101, which may be an insulator. A plurality of connection terminals 3 are installed in the connector body 101. However, the connection terminals 3 of the present invention are not limited to the connector 100, but may also be applied to other devices (such as flexible circuit boards, etc.). The connection terminal 3 is made of conductive materials such as copper. The connection terminal 3 has a terminal body 31. A mounting hole 32 is provided in the terminal body 31. The mounting hole 32 may be a round hole, but is not limited. The mounting hole 32 extends to one end of the terminal body 31. The depth of the mounting hole 32 is not limited, and at least it must be able to accommodate the fork 21 of the fork-shaped terminal 2. The wire diameter of the lead 1 is smaller than the diameter of the mounting hole 32. The present embodiment discloses a plurality of connection terminals 3, and the plurality of connection terminals 3 are arranged at intervals, so that the plurality of mounting holes 32 are arranged at intervals. The plurality of mounting holes 32 correspond to the plurality of leads 1 respectively, and the plurality of mounting holes 32 can be arranged in a row to facilitate the connection and fixation of the lead 1.

[0028] In this embodiment, the diameter D of the mounting hole 32 may be 0.7-1.1 mm, and the diameter D of the mounting hole 32 may be 0.9 mm. The wire diameter d of the lead wire 1 is smaller than the diameter D of the mounting hole 32, and the wire diameter d of the lead wire 1 may be 0.3-0.6 mm, and the wire diameter d of the lead wire 1 may be 0.4-0.5 mm.

[0029] In this embodiment, multiple (for example, two) leads 1 can be assembled together in the same mounting hole 32. During assembly, the multiple leads 1 can be pre-inserted into a channel 51 of a fixture 5 (for example, Figure 3As shown), the multiple leads 1 originally arranged horizontally in each channel 51 of the fixture 5 are arranged vertically, and then the fork-shaped terminal 2 is pressed from top to bottom, so that the lead 1 is accommodated in the accommodating space 22 of the fork-shaped terminal 2, so that the lead 1 is covered by the fork portion 21 of the fork-shaped terminal 2, the fixture 5 can be removed, and then the fork portion 21 of the fork-shaped terminal 2 and the lead 1 are pressed into the mounting hole 32 of the connecting terminal 3 (as shown in FIG. Figure 4 As shown in the figure, the fork portion 21 of the fork-shaped terminal 2 and the mounting hole 32 of the connecting terminal 3 form an interference fit, and the fork-shaped terminal 2 is guided and the friction force on the outside is used to achieve the effect of easy pressing in and difficult pulling out. The inner wall of the mounting hole 32 of the connecting terminal 3 will push the fork portion 21 of the fork-shaped terminal 2, and the lead 1 will be clamped in the fork portion 21 of the fork-shaped terminal 2, so that the lead 1 and the connecting terminal 3 are connected and fixed. In addition, the fork-shaped terminal 2 and the connecting terminal 3 can also be further fixed by glue, so that the fork-shaped terminal 2 and the connecting terminal 3 are more firmly combined.

[0030] Finally, the strip 23 of the entire row of fork-type terminals 2 can be removed from the breaking line 24 of the fork-type terminals 2 (eg, Figures 5 to 7 As shown in FIG. 1 , the fork-shaped terminal 2 left in the mounting hole 32 generates a friction force on the inner wall of the mounting hole 32 due to its expansion force, which can effectively prevent the installed lead wire 1 from being pulled out.

[0031] See also Fig.10 This embodiment further provides a method for quickly connecting a lead wire and a connecting terminal, comprising the following steps:

[0032] First, at least one lead wire 1, at least one fork-shaped terminal 2 and at least one connecting terminal 3 (such as Figures 1 to 7 The structures of the lead wire 1, the fork-shaped terminal 2 and the connecting terminal 3 are the same as those in the above embodiment, so they will not be described in detail.

[0033] Then, the lead 1 can be inserted into the channel 51 of the fixture 5, so that the leads 1 originally arranged horizontally in each channel 51 of the fixture 5 can be arranged vertically, and then the fork-shaped terminal 2 is pressed in so that the lead 1 is accommodated in the accommodating space 22 of the fork-shaped terminal 2, so that the lead 1 is covered by the fork portion 21 of the fork-shaped terminal 2.

[0034] Then, the fork portion 21 of the fork-shaped terminal 2 and the lead wire 1 are pressed into the mounting hole 32 of the connecting terminal 3, and an interference fit is formed between the fork portion 21 of the fork-shaped terminal 2 and the mounting hole 32 of the connecting terminal 3, and then the fork-shaped terminal 2 is guided and the friction force of the outer side is used to achieve the effect of easy pressing in and difficult pulling out. The fork-shaped terminal 2 and the connecting terminal 3 can also be further fixed by dispensing glue.

[0035] Finally, the strip 23 of the entire row of fork-shaped terminals 2 is removed from the break line 24 of the fork-shaped terminals 2. The fork-shaped terminals 2 remaining in the mounting holes 32 generate frictional force on the inner wall of the mounting holes 32 due to their expansion force, preventing the installed leads 1 from being pulled out. In this way, the lead 1 and the connection terminal 3 are connected and fixed, and the lead 1 and the connection terminal 3 are electrically connected and can be used for electrical signal transmission.

In this embodiment, the connecting terminal 3 has a terminal body 31, and a mounting hole 32 is provided in the terminal body 31. The mounting hole 32 extends to one end of the terminal body 31. The terminal body 31 extends to form a welding portion 33. The welding portion 33 can be welded to the circuit 202 on the flexible board body 201, so that the connecting terminal 3 is electrically connected to the flexible printed circuit 200. The lead wire 1 is accommodated in the accommodating space 22 of the fork-shaped terminal 2, and the fork portion 21 of the fork-shaped terminal 2 and the lead wire 1 are pressed into the mounting hole 32 of the connecting terminal 3, and an interference fit is formed between the fork portion 21 of the fork-shaped terminal 2 and the mounting hole 32, and the lead wire 1 is clamped in the fork portion 21 of the fork-shaped terminal 2, so that the lead wire 1 and the connecting terminal 3 are connected and fixed.
