The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] To achieve the above objectives, the present invention provides a FBC high-frequency high-speed connector. Figure 1 、 Figure 2 and Figure 7As shown, it includes a board end body 1 and a wire end body 2 connected to the board end body 1 by a buckle. The upper and lower sides of several parts inside the board end body 1 are composed of signal terminals 3 and power terminals 4. A double-layer soft cable 5 is inserted into the wire end body 2. Each end of the soft cable 5 is provided with a double row of contact terminals 6, which are respectively electrically connected to the signal terminal 3 and the power terminal 4. The rear part of the wire end body 2 is provided with a U-shaped lock component 7 for clamping the soft cable 5.

[0029] In this embodiment, two corresponding wire threading holes are set at the upper and lower rear ends of the line terminal body 2 for inserting the soft flat cable 5. A recessed hole 18 is provided at the front end of the line terminal body 2. After the soft flat cable 5 is inserted, a position is reserved in the recessed hole 18, and the double-row contact ends 6 of the soft flat cable 5 are detachably arranged on the upper and lower inner walls of the recessed hole 18, so as to facilitate electrical connection with the signal terminals 3 and the power terminals 4. The connection method between the soft flat cable 5 and the signal terminals 3 and the power terminals 4 is a double-row gold finger overlap method, which is easy to touch and can better ensure signal transmission. When the soft flat cable 5 needs to be replaced, it can be quickly disassembled, and the board terminal body 1 and the line terminal body 2 are connected by plug-in buckle, so that the connection between the two is reliable and stable.

[0030] Among them, reference Figure 3-6 As shown, the U-shaped lock assembly 7 includes a first plug-in block 8 and a second plug-in block 9, a square slot 10 is provided in a circle at the rear of the wire end body 2, and the first plug-in block 8 and the second plug-in block 9 are respectively provided on both sides of the square slot 10, and a plurality of protrusions 11 are provided on the end surface where the square slot 10 is located. The inner sides of the ends of the first plug-in block 8 and the second plug-in block 9 are provided with arc-shaped protrusions 12, which are snap-connected with the protrusions 11, and the middle parts of the first plug-in block 8 and the second plug-in block 9 are provided with outwardly protruding locking blocks 13, and both sides of the end of the flexible cable 5 are provided with card slots 14, and both sides of the square slot 10 are provided with through-holes 28, and the locking blocks 13 pass through the hole 28 and are locked with the card slots 14. In this way, after installing and inserting the two flexible flat cables 5, the first plug-in block 8 is inserted from the left side of the square slot 10, and the second plug-in block 9 is inserted from the right side of the square slot 10, so that the protrusion is snap-connected with the protrusion 11, so that the first plug-in block 8 and the second plug-in block 9 can be tightly locked on the square slot 10; at the same time, the locking block 13 of the first plug-in block 8 and the second plug-in block 9 will pass through the insertion hole 28 and then lock with the card slot 14, so that the flexible flat cable 5 is firmly connected to the cable end body 2, the flexible flat cable 5 is not easily pulled loose, and it is also relatively convenient to disassemble. You only need to use external force to push out the first plug-in block 8 and the second plug-in block 9, and the locking block 13 will separate from the card slot 14 to take out the flexible flat cable 5.

[0031] For further reference, Figure 4 and Figure 6As shown, elastic locking portions 15 extend from both sides of the cable terminal body 2. External snapping positions 16 are located on the central outer side of the elastic locking portions 15. Internal slots 17 are located on both sides of the board terminal body 1. The external snapping positions 16 and internal slots 17 are snap-connected. The board terminal body 1 and the cable terminal body 2 form a single small module. The external snapping positions 16 snap-connect with the internal slots 17, forming a stable male-female connection. During disassembly, external force simultaneously presses inward on both sides of the elastic locking portions 15, separating the external snapping positions 16 from the internal slots 17 and facilitating the removal of the cable terminal body 2 from the board terminal body 1.

[0032] Specifically, refer to Figure 4 and Figure 5 As shown, a recessed hole 18 is provided at the front end of the wire end body 2, and a contact protrusion 19 is provided in the board end body 1. The contact protrusion 19 is plugged into the recessed hole 18, so that the wire end body 2 and the board end body 1 are plugged into each other. In this way, the double-row contact terminals 6 of the flexible flat cable 5 contact the signal terminals 3 and the power terminals 4 to form an electrical signal connection, wherein the signal terminal 3 is located on one side of the power terminal 4, and an anti-fouling protrusion 20 is provided on one side of the inner wall of the recessed hole 18, and an anti-fouling recessed position 21 corresponding to the anti-fouling protrusion 20 is provided on one side of the contact protrusion 19 to prevent reverse plugging errors.

[0033] For further reference, Figure 2 and Figure 5 As shown, the outer surface of the board end body 1 is wrapped with a shielding cover 22, which can better prevent electromagnetic interference, ensure the stability of the signal during high-frequency transmission, and prevent the contact protrusion 19 from being damaged, thereby ensuring the reliability of the plug-in. Stop grooves 23 are provided on both sides of the board end body 1, and inner folding positions 24 are provided on both sides of the shielding cover 22. The inner folding positions 24 are engaged with the stop grooves 23, so that the shielding cover 22 is firmly set on the board end body 1 and is not easy to loosen.

A plurality of pins 27 corresponding to the welding holes 26 are provided at the end of the shielding cover 22. The PCB board 25 is electrically connected to the signal terminal 3 and the power terminal 4. The connection between the PCB board 25 and the pins 27, the signal terminal 3, and the power terminal 4 is processed by welding and SMT technology to effectively ensure firmness.

[0035] SMT (Surface Mount Technology) is an electronic assembly process that is mainly used to mount electronic components directly on the surface of a printed circuit board (PCB) instead of inserting pins into holes. It is suitable for the miniaturization, high performance and high reliability of electronic products.

[0036] In summary, the present invention provides an FBC high-frequency and high-speed connector, which effectively improves the stability of high-frequency signal transmission through the double-row contact terminals 6 that contact the signal terminals 3 and the power terminals 4 respectively, and the shielding cover 22 is set on the outside of the board end body 1. The U-shaped locking component 7 is connected to the wire end body 2 and the flexible flat cable 5 by a convex card, which facilitates the rapid disassembly, maintenance and assembly of the flexible flat cable 5. The small module design of the board end body 1 and the wire end body 2 is adopted, the structural volume is reduced, and the applicability is stronger.
