This specification and claims do not distinguish components based on differences in name, but rather on differences in function.

[0028] The inventors discovered that FPC line conversion requires soldering an onboard connector onto the FPC. This involves first soldering, then mating the connector on the other end (which contains terminals), then crimping the wires, and finally mating the mating connectors. This is done by connecting the male and female connectors with spring clips. Only in this way can the FPC etched circuit and the traditional wires be completely connected. However, this connection process is complex, inefficient, has a high error rate, and very low connection flexibility, resulting in extremely low quality of the finished product.
[0029] To address the above issues, the following is combined with the appendix. Figures 1-5 The present invention will be further described in detail with reference to specific embodiments, but this is not intended to limit the present invention.
[0030] Example 1
[0031] An integrated terminal, see Figures 1-2 It includes a wire connection part 1 and an elastic connection part 2. The wire connection part 1 includes at least one wire fixing structure 1a, which has a limiting hole 1b. The elastic connection part 2 includes at least one spring protrusion structure 2a. The elastic connection part 2 abuts against the wire connection part 1 through a first spring-loaded retaining part 3. The wire connection part 1 is connected to the elastic connection part 2 through an elastic folding part 4.
[0032] During line connection and switching, see Figure 5 Simply fix the wire 9 to the limiting hole 1b of the wire fixing structure 1a of the wire connection part 1, and then connect the FPC gold finger directly to the spring protrusion structure 2a of the elastic connection part 2. At the same time, the first spring pressure holding part 3 can ensure that the FPC gold finger will not over-pressure the wire connection part 1. The entire terminal structure is compact and highly reliable.
[0033] To better withstand the downward pressure of the first spring-loaded retaining part 3, the wire connection part 1 is provided with a protective buckle 1c. The protective buckle 1c is securely fixed to the wire connection part 1, and the first spring-loaded retaining part 3 abuts against the surface of the protective buckle 1c. The protective buckle 1c is shaped like a cuboid box, and its surface thickness is not less than that of the wire connection part 1. The first spring-loaded retaining part 3 presses against the top surface of the protective buckle 1c without damaging the wire 9 inside the cavity of the protective buckle 1c; that is, the protective buckle 1c effectively protects the wire 9.
[0034] Preferably, the horizontal length of the first spring-loaded retaining part 3 is less than the horizontal length of the protective buckle 1c. The horizontal length of the protective buckle 1c can be 1.2 to 1.6 times, for example, 1.3 times, 1.4 times, or 1.5 times, of the horizontal length of the first spring-loaded retaining part 3, so as to ensure that the protective buckle 1c can safely withstand the downward pressure of the first spring-loaded retaining part 3.
[0035] Preferably, the first spring-loaded retaining part 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 part 2, and the other end of the first buffer member 3a corresponds to the wire connecting part 1. The first buffer member 3a can play a vertical buffering role. The first buffer member 3a can extend from the left or right side of the elastic connecting part 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.
[0036] Preferably, the height of the protective buckle 1c is not greater than the height of the elastic folding part 4, and the height of the elastic folding part 4 can be equal to the sum of the height of the first buffer 3a and the height of the protective buckle 1c.
[0037] To prevent the elastic folding part 4 from undergoing undesirable 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 abuts 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 stable supporting and anti-deformation role between the elastic folding part 4 and the protective buckle body 1c.
[0038] Preferably, the second spring-loaded retaining part 5 includes at least two horizontal buffer members 5a arranged opposite each other. One end of the horizontal buffer member 5a is connected to the elastic folding part 4, and the other end of the horizontal buffer member 5a corresponds to the protective buckle body 1c. The shapes of each horizontal buffer member 5a can be the same or different. The shape of the horizontal buffer member 5a can be S-shaped, C-shaped, U-shaped or J-shaped, and the horizontal length of each horizontal buffer member 5a is equal.
[0039] Preferably, this embodiment has two wire fixing structures 1a of different sizes. The two wire fixing structures 1a are arranged close to the ground or spaced apart along the extension direction of the wire connection part 1. The wire fixing structure 1a closer to the protective buckle body 1c has two limiting holes 1b, and the wire fixing structure 1a farther from the protective buckle body 1c has one limiting hole 1b. The two wire fixing structures 1a and the protective buckle body 1c can be arranged in a straight line close to the ground or spaced apart.
[0040] Preferably, the wire fixing structure 1a can be a frame structure or a clamping structure, and the clamping structure can clamp and fix the wire 9.
[0041] Preferably, the protective buckle 1c is disposed between the wire fixing structure 1a and the elastic folding part 4. The wire fixing structure 1a, the limiting hole 1b, the protective buckle 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 at intervals along the extension direction of the elastic connecting portion 2. The elastic protrusion 2a closer to the elastic folding portion 4 is smaller than the elastic protrusion 2a farther from the elastic folding portion 4. The elastic protrusion 2a closer to the elastic folding portion 4 is vertically aligned with the second elastic pressure holding portion 5, and the first elastic pressure holding portion 3 is located between the two elastic protrusions 2a. This provides effective support for the two elastic protrusions 2a.
[0043] Among them, the small-sized spring protrusion structure 2a is an additional contact spring protrusion structure, and the large-sized spring protrusion structure 2a is a main contact spring protrusion structure.
[0044] Preferably, the spring-loaded protrusion 2a and the first elastic pressure retaining part 3 are located on opposite sides of the elastic connecting part 2, which is beneficial for the first elastic pressure retaining part 3 to support the spring-loaded protrusion 2a on the top side of the elastic connecting part 2 from the bottom side of the elastic connecting part 2.
[0045] Preferably, the wire connection part 1, the elastic connection part 2, the first elastic retaining part 3, the elastic folding part 4, and the second elastic retaining part 5 are each provided with a protective sleeve.
[0046] Preferably, the wire connection part 1, the elastic connection part 2, the first elastic retaining part 3, the elastic folding part 4, and the second elastic retaining part 5 can all be metal structures.
[0047] Example 2
[0048] Unlike Example 1, see [link to example]. Figure 3The elastic folding part 4 includes a first rigid part 4a, a soft part 4b, and a second rigid part 4c connected in sequence. The first rigid part 4a is connected to the wire connection part 1, and the second rigid part 4c is connected to the elastic connection part 2. The first rigid part 4a, the soft part 4b, and the second rigid part 4c can be connected to the second elastic retaining part 5 respectively.
[0049] Preferably, the wire connection part 1 has an adjustable buckle 6 correspondingly connected to the first spring-loaded retaining part 3. The adjustable buckle 6 can be provided 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 may have multiple elastic folds 4, that is, multiple elastic folds 4 are spaced apart on the wire connection part 1, so that different elastic folds 4 can be connected to different positions of the elastic connection part 2, which significantly improves the connection firmness between the wire connection part 1 and the elastic connection part 2 and the deformation resistance of the terminal structure.
[0051] Furthermore, the protective buckle body 1c has positioning holes 1d on opposite sides, and the positioning holes 1d are equipped with movable unlocking parts 7 and / or movable locking parts 8. The protective buckle body 1c may have movable unlocking parts 7 on both the left and right sides. The movable unlocking parts 7 can be press-on springs; pressing the movable unlocking parts 7 can release the conductor structure locked in the positioning holes 1d. Additionally, see... Figure 4 The protective buckle 1c can also have a movable locking part 8 on one side and a movable unlocking part 7 on the other side. The movable locking part 8 can be a locking ring nested on the left and right.
[0052] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.
[0053] In the connection of the entire electrical circuit, FPC cannot usually be fully applied to the entire circuit. When it is necessary to convert the etched printed circuit of the connected FPC in a two-dimensional plane to contact traditional conductors to support the adjustment of the wiring sequence, the existing technical solutions require three conductor connections to convert the etched circuit of the FPC to the output of traditional conductors. However, too many conductor connection points in the circuit are not conducive to the control of the overall electrical circuit connection stability. The integrated metal terminal of this application enhances the connection stability between the FPC gold finger and the metal terminal, realizing efficient, stable and fast connection between the FPC flexible circuit board and traditional conductors. The terminal has a primary spring-load retention structure and a secondary spring-load retention structure, which has extremely strong anti-deformation performance.
[0054] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
