[0025] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in name as a way to distinguish components, but rather use differences in the functions of the components as the criteria for distinction. For example, the term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0026] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "horizontal", "top", "bottom", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] In the present invention, the inventors found that the FPC circuit transfer requires welding an on-board connector on the FPC, that is, first use one welding, and then use it to mate with the other end connector, which contains terminals, and then rivet the wires, use one crimping, and then mate the mating connectors, that is, finally use one male and female end spring clip connection, so that the FPC etching loop can be completely turned out and the traditional wire outlet can be turned out. However, such connection steps are complicated, the processing efficiency is low, the error rate is extremely high, and the connection flexibility is extremely low, which makes the quality of the finished product extremely low.

[0029] In order to solve the above problems, the following Figures 1 to 5 The present invention is further described in detail with reference to the accompanying drawings and specific examples, but is not intended to limit the present invention.

[0030] Example 1

[0032] During line connection and transfer, see Figure 5 It is only necessary to fix the wire 9 in the limiting hole 1b of the wire fixing structure 1a of the wire connecting part 1, and then directly connect the FPC gold finger to the elastic protrusion structure 2a of the elastic connecting part 2. At the same time, the first elastic holding part 3 can ensure that the FPC gold finger will not over-press the wire connecting part 1. The entire terminal structure is compact and highly reliable.

[0033] To better enable the wire connector 1 to withstand the downward pressure of the first spring-loaded retaining portion 3, the wire connector 1 is provided with a protective buckle 1c. The protective buckle 1c is securely fixed to the wire connector 1, and the first spring-loaded retaining portion 3 abuts against the surface of the protective buckle 1c. The protective buckle 1c is shaped like a square box, and its surface thickness is no less than that of the wire connector 1. The first spring-loaded retaining portion 3 abuts against the top surface of the protective buckle 1c, preventing damage to the wire 9 within the inner cavity of the protective buckle 1c. This means that the protective buckle 1c effectively protects the wire 9.

[0034] Preferably, the horizontal length of the first spring-pressing retaining portion 3 is smaller than the horizontal length of the protective buckle body 1c. The horizontal length of the protective buckle body 1c can be 1.2 to 1.6 times the horizontal length of the first spring-pressing retaining portion 3, for example, 1.3 times, 1.4 times, or 1.5 times, to ensure that the protective buckle body 1c can safely withstand the downward pressure of the first spring-pressing retaining portion 3.

[0035] Preferably, the first spring-pressed retaining portion 3 includes at least two first buffer members 3a arranged opposite to each other, one end of the first buffer member 3a is connected to the elastic connecting portion 2, and the other end of the first buffer member 3a corresponds to the wire connecting portion 1. The first buffer member 3a can play a role of vertical buffering. The first buffer member 3a can extend from the left or right side of the elastic connecting portion 2 to the protective buckle body 1c. The shapes of each first buffer member 3a can be the same or different. The shape of the first buffer member 3a can be S-shaped, C-shaped, U-shaped or J-shaped. The height of each first buffer member 3a is equal, and the surface thickness of the first buffer member 3a is between 0.95 times and 1.15 times the surface thickness of the protective buckle body 1c.

[0037] In order to prevent the elastic folding part 4 from producing adverse horizontal deformation, a second spring-loaded retaining part 5 is provided on the side of the elastic folding part 4. The elastic folding part 4 is abutted against the surface of the protective buckle body 1c through the second spring-loaded retaining part 5, so that the second spring-loaded retaining part 5 plays a role of stable support and anti-deformation between the elastic folding part 4 and the protective buckle body 1c.

[0038] Preferably, the second spring-loaded retaining portion 5 includes at least two horizontal buffer members 5a disposed opposite each other, one end of each horizontal buffer member 5a being connected to the elastic folded portion 4, and the other end of each horizontal buffer member 5a corresponding to the protective buckle body 1c. The shapes of the horizontal buffer members 5a can be the same or different, and can be S-shaped, C-shaped, U-shaped, or J-shaped, and the horizontal lengths of the horizontal buffer members 5a are equal.

[0039] Preferably, this embodiment has two wire fixing structures 1a of different sizes, and the two wire fixing structures 1a are arranged closely or spaced apart along the extension direction of the wire connecting part 1. The wire fixing structure 1a close to the protective buckle body 1c is provided with two limiting holes 1b, and the wire fixing structure 1a away from the protective buckle body 1c is provided with one limiting hole 1b. The two wire fixing structures 1a and the protective buckle body 1c can be arranged closely or spaced apart in a straight line.

[0040] Preferably, the wire fixing structure 1a may be a frame-type structure or a clamping structure, and the clamping structure may clamp and fix the wire 9.

[0041] Preferably, the protective buckle body 1c is arranged between the wire fixing structure 1a and the elastic folding part 4, and the wire fixing structure 1a, the limiting hole 1b, the protective buckle body 1c, the second spring-loaded retaining part 5 and the elastic folding part 4 are all arranged in the same straight line, thereby improving the space utilization of the terminal structure.

[0042] Preferably, this embodiment has two elastic protrusions 2a of different sizes, which are arranged spaced apart along the extension direction of the elastic connecting portion 2. The elastic protrusion 2a near the elastic folded portion 4 is smaller than the elastic protrusion 2a away from the elastic folded portion 4. The elastic protrusion 2a near the elastic folded portion 4 is vertically aligned with the second elastic holding portion 5, and the first elastic holding portion 3 is located between the two elastic protrusions 2a, thereby effectively supporting the two elastic protrusions 2a.

[0043] The small-sized spring-protrusion structure 2a is an additional contact spring-piece protrusion structure, and the large-sized spring-protrusion structure 2a is a main contact spring-piece protrusion structure.

[0044] Preferably, the elastic convex structure 2a and the first elastic pressure holding portion 3 are respectively located on opposite sides of the elastic connection portion 2, which is conducive to the first elastic pressure holding portion 3 supporting the elastic convex structure 2a on the top side of the elastic connection portion 2 from the bottom side of the elastic connection portion 2.

[0047] Example 2

[0048] The difference from Example 1 is that, see Figure 3The elastic folding part 4 includes a first hard part 4a, a soft part 4b and a second hard part 4c connected in sequence, the first hard part 4a is connected to the wire connecting part 1, the second hard part 4c is connected to the elastic connecting part 2, and the first hard part 4a, the soft part 4b and the second hard part 4c can be respectively connected to the second spring-pressing holding part 5.

[0049] Preferably, the wire connecting part 1 has an adjustable buckle 6 corresponding to the first spring-loaded retaining part 3. The adjustable buckle 6 can be set on the top surface of the protective buckle body 1c. The adjustable buckle 6 is used to lock the first spring-loaded retaining part 3 in the horizontal direction to prevent the first spring-loaded retaining part 3 and the protective buckle body 1c from loosening.

[0050] Preferably, the terminal can have multiple elastic folding parts 4, that is, multiple elastic folding parts 4 are arranged at intervals on the wire connecting part 1, so that different positions of the elastic connecting part 2 can be connected to different elastic folding parts 4, respectively, which significantly improves the connection firmness between the wire connecting part 1 and the elastic connecting part 2 and the deformation resistance of the terminal structure.

[0051] Furthermore, positioning holes 1d are provided on opposite sides of the protective buckle body 1c, and the positioning holes 1d are provided with movable unlocking members 7 and / or movable locking members 8. The protective buckle body 1c can be provided with movable unlocking members 7 on both sides, respectively. The movable unlocking members 7 can be press springs. Pressing the movable unlocking members 7 can release the conductor structure locked in the positioning holes 1d. Figure 4 The protective buckle body 1c can also be provided with a movable locking member 8 on one side and a movable unlocking member 7 on the other side. The movable locking member 8 can be a locking ring nested on the left and right.

[0052] The other structures of this embodiment are the same as those of embodiment 1 and will not be described again here.

[0053] In the connection of the entire electrical circuit, FPC is usually not fully applied in the entire circuit. When the connected FPC needs to be converted from a two-dimensional etched printed circuit to a traditional wire to support the adjustment of the line sequence, the existing technical solution converts the FPC's etched circuit into a traditional wire outlet, requiring three conductor connections. The excessive number of conductor connection points in the circuit is not conducive to controlling the stability of the entire electrical circuit connection. The integrated metal terminal of this application enhances the stability of the connection between the FPC gold finger and the metal terminal, achieving efficient, stable and fast connection between the FPC flexible circuit board and the traditional wire. The terminal has a primary spring force retention structure and a secondary spring force retention structure, and has extremely strong anti-deformation performance.

Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention fall within the scope of protection of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
