DETAILED DESCRIPTION

[0015] The specific structure of the present invention is described below in conjunction with the accompanying drawings:

[0016] A flexible cable connector, see Figure 2 and Figure 3As shown, it includes a board end plastic part 1 and a wire end plastic part 2 that are connected by snapping. The snapping connection can adopt a conventional snapping connection structure, such as a buckle hole is provided on one component, and a buckle platform that cooperates with the buckle hole is provided on the other component, and the buckling connection is achieved by the buckle platform cooperating with the buckle hole. In this embodiment, a concave cavity 10 is provided in the middle of the board end plastic part 1, and terminals 3 are installed on the board end plastic part 1 at relative positions on opposite sides of the concave cavity 10. Each terminal 3 is arranged in the terminal hole of the board end plastic part 1, and each terminal 3 includes a fixing part 31, an elastic connecting part 33 and a power connection part 32. The elastic connecting part 33 connects the fixed part 31 and the power connecting part 32, the fixed part 31 is fixed in the terminal hole, the end of the power connecting part 32 has a contact point extending into the cavity 10, the fixed part 31 has a power connecting pin 311 extending out of the board end plastic part 1, the wire end plastic part 2 has a crimping boss 21 suitable for engaging with the cavity 10, a section of the flexible flat cable 4 (such as an FFC flat cable) is clamped between the crimping boss 21 and the cavity 10, and the contact point contacts the exposed metal wire on the flexible flat cable 4 to achieve electrical connection. The flexible flat cable connector of the present invention is used to buckle and connect the line end plastic part 2 with the board end plastic part 1. A section of the flexible flat cable 4 is clamped between the concave cavity 10 and the crimping boss 21. Under the elastic force of the elastic connection part 33, the contact point contacts the exposed metal wire 41 on the flexible flat cable 4 to achieve electrical connection. When the scheme in this embodiment is used in a cable set for a TV backlight panel, it can be realized that a flexible flat cable runs through all the circuits on the LED light board (see Figure 4 As shown), it is easy to lay out, and the flexible flat cable (such as FFC flat cable) replaces the electronic wire, and there is no need to save the manual steps such as wire stripping, riveting terminals, and installing housing, simplifying the production process, which is beneficial to improving work efficiency and reducing production costs; by buckling the board end plastic part 1 with the line end plastic part 2, the exposed metal wire on the flexible flat cable 4 contacts the contact point on the terminal to achieve electrical connection, and a break is set on the metal wire of the flexible flat cable in the area between the two opposite terminals as needed, so that the power connection pins 311 of the two opposite terminals are respectively connected to the incoming line terminal and the outgoing line terminal of the line on the LED lamp board, so that the current flows through the line on the LED lamp board, that is, the line on the LED lamp board is connected in series with the power supply line; compared with the same electronic wire solution, under the premise that the number of LED lamp boards used is equal, the wiring design is simpler, and the wiring is beautiful and neat.

[0017] In this embodiment, the terminal 3 is an integrated stamping structure, and the terminal 3 can be processed by stamping a metal sheet. In this embodiment, the elastic connection part 33 is a wavy line shape, and the wavy line shape of the elastic connection part 33 makes the elastic connection part 33 have telescopic elasticity.

[0018] In this embodiment, the corresponding portion of the flexible flat cable 4 is connected to the surface of the crimping boss 21 by gluing.

[0019] In this embodiment, the fixing portion 31 is inserted into the terminal hole with interference fit, and teeth are provided on the edge of the fixing portion 31. After the fixing portion 31 is inserted into the terminal hole, the presence of the teeth further enhances the bonding force between the fixing portion 31 and the board end plastic part.

[0020] As a further improvement of this embodiment, the power connection part 32 has a protruding stopper 321, and a limiting step 11 is provided at the inner port of the terminal hole. The stopper 321 abuts against the limiting step 11 to limit the power connection part 32 and prevent the entire power connection part 32 from extending out of the terminal hole and entering the concave cavity 10.

[0021] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
