Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The present embodiment provides an FPC connector terminal, which is applied to electronic devices, automotive electronics, and power batteries, and can be used in electronic devices to electrically connect different functional modules in the electronic devices, such as a television screen and a motherboard, so as to implement a specific function of the electronic devices. The FPC is applied to automotive electronics and power batteries, and can realize communication among automotive electronic components, voltage or temperature acquisition of a battery module and communication among modules. The existing FPC connector terminal is clamped on a single surface, or the terminal clamped up and down is independently processed, so that the cost of a die is high. And the upper and lower terminals cannot be simultaneously deformed, so that there is a risk of poor contact.

In order to solve the above problem, as shown in fig. 1 and fig. 2, the FPC connector terminal of the present embodiment includes an upper terminal 100, a bending section 300, and a lower terminal 200, wherein the bending section 300 is bent by 180 ° from a plane so that the lower terminal 200 abuts against and aligns with the upper terminal 100, and the FPC 10 can be sandwiched between the upper terminal 100 and the lower terminal 200. Wherein the bending section 300 has the upper terminal 100, the bending section 300, and the lower terminal 200 in one plane before being bent so that the FPC 10 connector terminal can be integrally molded without separate manufacturing, thereby making the mold cost low. In addition, since the FPC connector terminal of the present embodiment is integrally formed, the same deformation amount can be maintained when the upper terminal 100 and the lower terminal 200 simultaneously receive an external force, a gap generated due to the difference in deformation amount between the upper terminal 100 and the lower terminal 200 does not occur, and the stability of holding the FPC 10 is ensured, and the FPC 10 can be in good contact with the FPC.

Further, as shown in fig. 1 and 2, the bending section 300 is located at one end of the upper terminal 100 and/or the lower terminal 200 far from the FPC 10, since the upper terminal 100 and the lower terminal 200 generate a clamping force to clamp the FPC 10 by elastic deformation of metal, and the bending section 300 is equivalent to a fulcrum of the elastic deformation, the distance that the upper terminal 100 and the lower terminal 200 can be separated within the metal elastic deformation range increases as the distance between the bending section 300 and the clamping end increases, the thickness that the FPC 10 can be clamped increases, and the range suitable for clamping the FPC 10 increases.

Further, as shown in fig. 1 and 2, the holding end of the upper terminal 100 is recessed downward to form an upper holding portion 130, the upper holding portion 130 abuts against the lower terminal 200 when the FPC 10 is not held, and the FPC 10 is held between the holding portion and the lower terminal 200 when the FPC 10 is held. Compared with the FPC 10 clamped between two planes, the upper clamping portion 130 can make the clamping force larger, thereby ensuring that the FPC 10 is clamped more stably.

Specifically, the upper clamping portion 130 includes a folded angle section 131 and a raised section 132 connected to each other, and an included angle is formed between the folded angle section 131 and the raised section 132 so that the upper clamping portion 130 is in a "V" shape. The lowest point of the V shape has larger clamping force compared with other structures, so that the stability of clamping the FPC 10 is ensured, and further, no meshing teeth are required to be arranged, so that the conductor cannot be damaged to a large extent, and the plating layer of the conductor is prevented from being damaged.

Alternatively, the included angle between the bent angle section 131 and the raised section 132 is 45-60 degrees, and the clamping effect of the V-shaped upper clamping part 130 in the range is optimal. Optionally, the included angle between the bent angle section 131 and the upward-flying section 132 is 45 °, 50 °, 55 °, 60 °.

Further, the raised section 132 is a free end of the upper terminal 100, and the raised section 132 and the lower terminal 200 form a certain included angle, so that the abutting part of the upper clamping portion 130 and the lower terminal 200 is easily separated, thereby facilitating clamping of the FPC 10.

Further, the lower terminal 200 includes a lower abutting portion 210, a cantilever portion 220 and a lower positioning portion 230 connected to each other, wherein the cantilever portion 220 extends downward at an obtuse angle with respect to the lower abutting portion 210, the lower positioning portion 230 is parallel to the lower abutting portion 210, and the upper clamping portion 130 abuts against the lower positioning portion 230. The cantilever portion 220 makes the lower positioning portion 230 and the lower abutting portion 210 have a certain height difference, so as to accommodate the upper clamping portion 130 which is concave downwards, so that the upper clamping portion 130 and the lower positioning portion 230 cannot be in an elastic deformation state when abutting, and further the upper clamping portion 130 and the lower positioning portion 230 cannot generate plastic deformation when clamping the thicker FPC 10, thereby avoiding the clamping force of the terminal of the FPC connector from being invalid.

Further, the upper terminal 100 further includes an upper abutting portion 110 and a transition section 120, the upper abutting portion 110 abuts against the lower abutting portion 210, the transition section 120 is located between the upper abutting portion 110 and the upper clamping portion 130, and the transition section 120 extends downward at an obtuse angle with the upper abutting portion 110. The connection between the transition section 120 and the upper clamping portion 130 is equivalent to adding a fulcrum on the basis of the bending section 300, so that the metal elasticity of the FPC connector terminal is larger. Therefore, when the FPC 10 is clamped, when the thickness of the FPC 10 is very thick, the transition section 120 drives the upper abutting portion 110 to rotate to be parallel to the upper abutting portion 110 by using the connecting line between the transition section 120 and the upper clamping portion 130 as an axis, and if the lower FPC 10 cannot be accommodated at this time, the upper abutting portion 110 rotates relative to the transition section 120 so that the distance between the upper clamping portion 130 and the lower abutting portion 210 is larger to accommodate the FPC 10.

Further, a lower clamping portion 231 is formed on the lower positioning portion 230 in an upward protruding manner, and when the FPC connector terminal is unloaded, the lower clamping portion 231 abuts against the upper clamping portion 130. When the FPC connector terminal clamps the FPC 10, the FPC 10 is clamped between the upper clamping portion 130 and the lower clamping portion 231. The lower clamping portion 231 protruding upwards not only enables the upper clamping portion 130 and the lower clamping portion 231 to be abutted without a gap when the FPC 10 is not clamped, but also guarantees clamping force between the upper clamping portion 130 and the lower clamping portion 231, and therefore clamping stability is further guaranteed.

Specifically, the lower clamping portion 231 is a trapezoidal boss, wherein an upper surface of the trapezoidal boss abuts the upper clamping portion 130. When the FPC 10 is clamped between the upper clamping portion 130 and the lower clamping portion 231, the upper clamping portion 130 is in line contact with the FPC 10, the lower clamping portion 231 is in surface contact with the FPC 10, and the surface contact can limit more degrees of freedom of the FPC 10, so that the FPC 10 is clamped more stably, and the phenomenon that the FPC 10 is damaged due to too sharp clamping points can be avoided.

Alternatively, the FPC connector terminal of the present embodiment is made of copper material, which has good ductility and thus facilitates molding. Moreover, the surface of the FPC connector is plated with the metallic tin, and the tin-plated layer is not easy to react with oxygen in the air, so that the copper material can be protected from being oxidized due to contact with external substances, and the service life of the terminal of the FPC connector is ensured.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements, and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
