[0026] The following will be combined with specific embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0027] See also Figures 1 to 9 As shown, the structure of the utility model is: an automatic locking FPC connector, including a plastic body 1, a slot 101 for plugging in FPC6 is opened in the plastic body 1, a terminal piece contacting with FPC6 is arranged in the slot 101, the bottom of the plastic body 1 is a hollow structure and is buckled with a bottom cover 3, and the top of the plastic body 1 is symmetrically provided with locking grooves 102 connected with the slot 101, and elastic arms 4 extending upward are symmetrically arranged on both sides of the rear end of the bottom cover 3, one end of the two elastic arms 4 is connected to the pressing cover 2, and the other end of the two elastic arms 4 is provided with a lock 5, and the lock 5 extends downward from the lock groove 102 to the slot 101. Specifically, when FPC6 is inserted from the front end of the slot 101, the end of FPC6 will push the lock buckle 5 upward. After being inserted into place, the slot 601 on the FPC6 is just located below the lock buckle 5. Under the elastic force of the elastic arm 4, the lock buckle 5 is reset downward and automatically engaged with the slot 601 to achieve automatic locking. When unlocking is required, the pressing cover 2 is pressed down to make the elastic arm 4 lift the lock buckle 5. After the lock buckle 5 is separated from the slot 601, the FPC6 can be pulled out. After releasing the pressing cover 2, the lock buckle 5 returns to its original position under the elastic force of the elastic arm 4. Compared with the existing flip-top products, the automatic locking FPC connector of the utility model is more convenient and quick to operate when plugging in or unlocking.

[0028] Furthermore, the pressing cover 2, the bottom cover 3, the elastic arm 4 and the lock buckle 5 are an integrally formed plastic structure.

[0029] like Figure 4 As shown, the lower end of the lock buckle 5 is provided with an inclined surface 501, and the inclined surface 501 is provided to facilitate lifting the lock buckle 5 when the FPC is inserted.

[0031] like Figure 5 , Fig. 9 As shown, a plurality of partitions 301 are provided on the bottom cover 3 at intervals, and a terminal groove 302 for accommodating the terminal piece is formed between two adjacent partitions 301, so as to ensure the stability of the terminal piece when the FPC is plugged in.

[0032] like Figure 8 , Fig. 9As shown, the terminal member includes a plurality of first terminals 103 arranged in parallel at the front end of the slot 101 and a plurality of second terminals 105 arranged in parallel at the rear end of the slot 101, and the first terminals 103 and the second terminals 105 are arranged in a terminal slot 302 at intervals. Specifically, the ends of the first terminals 103 and the second terminals 105 are both provided with bent portions, and the bent portions protrude from the partitions 301 on both sides of the terminal slot 302. When the FPC is inserted into the connector, the bent portions on the first terminals 103 and the second terminals 105 contact with the metal contacts on the FPC, thereby improving the connection stability.

[0033] like Figure 5 As shown, by providing a groove 201 on the upper surface of the pressing cover 2, the pressing cover 2 can be pressed into the groove 201 when pressed down, which is convenient for pressing and unlocking.

[0034] When in use, plug in FPC6 and insert it from the front end of the slot 101. The end of FPC6 will push up the lock buckle 5. After being inserted into place, the slot 601 on FPC6 is just below the lock buckle 5. Under the elastic force of the elastic arm 4, the lock buckle 5 is reset downward and automatically engaged with the slot 601 to achieve automatic locking. When unlocking is required, the pressing cover 2 is pressed down to make the elastic arm 4 lift the lock buckle 5. After the lock buckle 5 is separated from the slot 601, the FPC6 can be pulled out. After releasing the pressing cover 2, the lock buckle 5 returns to its original position under the elastic force of the elastic arm 4. Compared with the existing flip-top products, the automatic locking FPC connector of the utility model is more convenient and quick to operate when plugging in or unlocking.

[0035] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
