[0030] Please see Figure 1 This application provides a quick-assembly FFC connector, including a first connector 1, a second connector 2, an FFC 3, a first positioning mechanism 4, and a second positioning mechanism 5. The second connector 2 and the first connector 1 are mated together, and one end of the FFC 3 is inserted into the second connector 2 for electrical connection with the first connector 1. The first positioning mechanism 4 is used to fix one end of the FFC 3 onto the second connector 2; the second positioning mechanism 5 is used to lock the mated second connector 1 and the first connector 2.

[0031] Please see Figure 2 In this embodiment, one end face of the first connector 1 is provided with a connector groove 11 for interlocking with the second connector 2. A plurality of terminal conductors 12 are also inserted into the first connector 1; one end of each terminal conductor 12 is located within the connector groove 11 for electrical connection to one end of the FFC3, and the other end of each terminal conductor 12 is located on the side of the first connector 1 away from the second connector 2 for soldering to the circuit board. Furthermore, grounding plates 13 are provided on both outer ends of the first connector 1.

[0032] Please see Figure 3-5 The second connector 2 is provided with several parallel cable trays 21 extending at intervals along the direction of the first connector 1. One end of the FFC3 is electrically connected to one end of the terminal conductor 12 through the cable tray 21. During assembly, the FFC3 is inserted into the cable tray 21 from the side of the second connector 2 away from the first connector 1 and then electrically connected to one end of the terminal conductor 12.

[0033] Furthermore, the two inner sidewalls of the cable tray 21 include a straight section 211 and a draft section 212 connected to each other. The straight section 211 is located on one side of the mating ends of the second connector 1 and the first connector 2. The draft section 212 extends in the opposite direction to the insertion of the FFC3. The gap between the FFC3 and the straight section 211 is smaller than the gap between the FFC3 and the draft section 212. In this application, the draft section 212 facilitates demolding during the manufacturing of the cable tray 21, while the straight section 211 ensures that the gap between the FFC3 and the sidewall of the cable tray 21 is small, making it less prone to shaking.

[0034] Furthermore, the end of the ribbon cable slot 21 near the first connector 2 and the second connector 1 is provided with an observation slot 213. The observation slot 213 is set perpendicular to the mating surfaces of the second connector 2 and the first connector 1. When the FFC3 is inserted into the ribbon cable slot 21, by comparing the gold fingers of the FFC3 with the observation slot 213, it is determined whether the FFC3 is misaligned when inserted into the ribbon cable slot 21. If there is misalignment, the FFC3 needs to be re-inserted and its insertion position adjusted.

[0035] Furthermore, the second connector 2 has a first positioning hole 22 on its upper and lower surfaces, and the FFC3 has a second positioning hole 31. When the FFC3 is inserted into the cable tray 21, the first positioning hole 22 and the second positioning hole 31 are aligned.

[0036] Please see Figure 3 and Figure 6 The first positioning mechanism 4 includes a fixing part 41 and a positioning post 42. The two ends of the fixing part 41 are engaged with the two outer ends of the second connector 2; one end of the positioning post 42 is fixed to the fixing part 41, and the other end passes through the first positioning hole 22 and the second positioning hole 31. In this application, the arrangement of the first positioning hole 22, the second positioning hole 31, and the first positioning mechanism 4 not only fixes the FFC3 inserted into the cable tray 21 onto the first connector 2, but also reduces the assembly difficulty of the FFC3 and the first connector 2, and improves the overall assembly efficiency of the connector.

[0037] The second positioning mechanism 5 includes a spring arm 51 and a reinforcing locking member 52. The spring arm 51 is disposed on the upper end face of the second plug-in seat 2, with one end fixedly connected to the second plug-in seat 2 near the side where the second plug-in seat 2 and the first plug-in seat 1 are inserted. The other end is located above the second plug-in seat 2 and is provided with a protrusion 511. Correspondingly, the upper inner sidewall of the plug-in groove 11 is provided with a guide groove 111 along the insertion direction of the first plug-in seat 1 and the second plug-in seat 2. A locking platform is provided at one end of the guide groove 111 near the opening of the plug-in groove 11. When the second plug-in seat 2 is inserted into the plug-in groove 11, the spring arm 51 is accommodated in the guide groove 111, and finally the protrusion 511 engages with the locking platform, thereby locking the first plug-in seat 1 and the second plug-in seat 2 after insertion.

[0038] Furthermore, the upper end face of the second connector 2 is provided with a groove 23. Preferably, the groove 23 is arranged along the mating direction of the first connector 1 and the second connector 2. The reinforcing locking member 52 is slidably accommodated in the groove 23. When the protrusion 511 engages with the locking platform, the reinforcing locking member 52 abuts against the end of the elastic arm 51 away from the inner wall of the connector groove 11, thereby preventing the first connector 1 and the second connector 2 from being locked out after mating, further enhancing the connection stability of the connector.

[0039] In this embodiment, the reinforcing locking member 52 includes an operating part 521, a sliding part 522, an abutting part 523, and a locking part 524. One end of the sliding part 522 is fixed to the operating part 521, and the other end extends into the slide groove 23, with its two outer surfaces tightly abutting against the sidewall of the slide groove 23. One end of the abutting part 523 is fixed to the operating part 521, and the other end abuts against the end of the elastic arm 51 away from the inner wall surface of the insertion slot 11. One end of the locking part 524 is fixed to the operating part 521, and the other end is used to lock into the elastic arm 51. In other embodiments, the end of the locking part 524 away from the operating part 521 may also be connected to the first insertion seat 1 or the second insertion seat 2.

[0040] Furthermore, the sliding part 522 consists of two parallel sliding rods, one end of which is fixedly connected to the two ends of the operating part 521, and the other end extends into the slide groove 23, with its outer side abutting against the inner wall of the slide groove 23. The locking part 524 is located between the two sliding rods.

[0041] Furthermore, the side wall of the slide 23 is provided with a limiting part 231, and the operating part 521 is provided with a bayonet. The limiting part 231 is accommodated in the bayonet to prevent the reinforcing locking member 52 from coming out from above the slide 23.

[0042] Furthermore, the groove 23 and the limiting part 231 protrude from the end face of the second plug seat 2 away from the first plug seat 1. This arrangement ensures that even if the thickness of the second plug seat 2 decreases along the insertion direction, the reinforcing locking member 52 remains stable in sliding within the groove 23 and is not easily dropped from the end of the second plug seat 2 away from the first plug seat 1.

[0043] In this application, the elastic arm 51 and the reinforcing locking member 52 are provided for double locking after the first plug-in 1 and the second plug-in 2 are plugged in. After locking, even if the connector is shaken by the external environment, its plug-in lock is not easily released, thereby improving the connection stability of the connector.

[0044] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
