detailed description:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1-8, the utility model is a rear lock FPC connector, which includes: a base 1, a terminal 2, a lock cover 3 and a connecting piece 4.

The base 1 is injection-molded with insulating plastic material. The base 1 and the front surface of the base 1 are respectively provided with a slot 11 for inserting the FPC data line 5 , and a plurality of terminal slots 10 evenly distributed in the slot 11 . The terminal groove 10 runs through the base 1 transversely. Side walls 14 are formed on both longitudinal ends of the base 1 . A gap 12 is formed between the two side walls 14 on the upper part of the base 1 from the rear end to the front.

A raised strip 13 is formed on the upper part of the base 1 relative to the front end of the notch 12, and the terminal groove 10 includes: a lower groove 101 opened backward from the front end of the base 1 and penetrating through the base 1; The upper groove 102 that offers before. Due to the existence of the gap 13 , the rear portion of the lower slot 101 of the terminal slot 10 is exposed to the base 1 .

As shown in FIGS. 3 and 4 , the protruding strip 13 is located between the two sidewalls 14 , and a gap 15 is formed between the protruding strip 13 and the two sidewalls 14 . The communication slot 16 is used to accommodate both ends of the pivot shaft 31 of the lock cover 3 .

As shown in FIG. 5 , the terminal 2 is integrally formed of metal material, which includes: a clamping part 21 and a welding part 22. The clamping part 21 is inserted from the rear end of the terminal groove 10, and the clamping part 21 is located at the insertion position. At the groove 11 , the welding portion 22 is exposed on the rear end surface of the base 1 .

The clamping part 21 of the terminal 2 includes: an upper arm 211 and a lower arm 212, and the welding part 22 extends backward from the junction of the upper arm 211 and the lower arm 212; wherein the upper arm 211 is inserted into the upper slot 102 , the lower arm 212 is inserted into the lower slot 101 .

A contact point 2121 is formed on the inner surface of the front end of the lower arm 212 , and a positioning protrusion 2122 is formed on the inner surface of the lower arm 212 close to the welding portion 22 .

As shown in FIG. 6 , when installing the terminal 2 , insert the terminal 2 from the rear side of the terminal slot 10 , insert the upper arm 211 of the terminal 2 into the upper slot 102 , and insert the lower arm 212 into the lower slot 101 . Until the terminal 2 is fully inserted, at this time, the positioning protrusion 2122 on the terminal 2 is matched with the corresponding card point in the lower groove 101, so that the terminal 2 is fixed on the base 1, and the slot 11 on the base 1 is located between the upper arm 2111 and the lower arm 212 .

After the terminal 2 is assembled on the base 1, the rear section of the upper arm 211 of the terminal 2 will be exposed at the position of the notch 12 of the base 1, and a lock cover 3 is arranged at the notch 12, and the two ends of the lock cover 3 are longitudinally pivoted on the base. On the seat 1, the turnover of the lock cover 3 is realized. The specific structure is as follows:

The rear end surfaces of the two side walls 14 of the base 1 are respectively provided with side grooves 17 , and a connecting piece 4 is plugged and fixed in the side grooves 17 . The connecting piece 4 is formed with a first extension arm 41 and a second extension arm 42 forward, and a bending piece 43 is formed at the bottom of the connecting piece 4 outward, and the first extension arm 41 and the second extension arm 42 are inserted into Corresponding to the side slot 17 , the bent piece 43 is exposed at the bottom of the side slot 17 .

After the connecting piece 4 is inserted into the side slot 17 , its first extension arm 41 is exposed in the gap 15 after being inserted into the side slot 17 .

As shown in Figures 7 and 8, the lower surface of the lock cover 3 has several cover grooves 32 corresponding to each terminal 2; the upper surface of the lock cover 3 has a lock cover gap 33 from front to back, and the cover The groove 32 is exposed by the notch 33 of the lock cover; the pivot shaft 31 is located at the front end of the notch 33 of the lock cover. Both ends of the pivot shaft 31 extend into the gap 15 through the communication groove 16, and the end of the pivot shaft 31 is located below the first extension arm 41 inserted into the gap 15, that is, the pivot shaft 31 passes through the first extension arm 41. An extension arm 41 is bounded in the gap 15 . In this way, the two ends of the pivot shaft 31 of the lock cover 3 are restricted at the communicating groove 16 by the first extension arm 41, forming a pivot structure.

When installing, it is necessary to install the lock cover 3 first, so that the pivot shaft 31 of the lock cover 3 is inserted into the position of the communication groove 16, and then the connecting piece 4 is plugged and fixed in the side groove 17. As the connecting piece 4 continues to Inserted into the side slot 17, the first extension arm 41 will protrude from the gap 15 and just press the end of the pivot shaft 31 extending thereunder just below it.

The cover notch 33 on the lock cover 3 is to allow the lock cover 3 to avoid the convex strip 13 during the flipping process. Similarly, the cover groove 32 provided on the lock cover 3 is for avoiding the upper and lower arms 211 , 212 of the terminal 2 .

Referring to 8, when using the utility model, the utility model will be fixed on the circuit board and other devices, first rotate the lock cover 3 to the open position, then insert the FPC connecting wire into the slot 11 of the utility model, The contact portion of the FPC connection wire is inserted into the holding portion 21 of the terminal 2 . Then rotate the lock cover 3 to make it cover with the base 1 . Due to the existence of the cover groove 32, the lock cover 3 can be opened or closed smoothly. At the same time, the pivot shaft 31 of the lock cover 3 forms a structure similar to a camshaft. When the lock cover 3 is covered on the base 1, the diameter of the area where the cover groove 32 is set on the pivot shaft 31 increases, so that the slot 11 Interfering with the entrance of the slot 11, the width of the entrance of the slot 11 is narrowed, just to form a downward compression on the FPC connecting wire inserted into the slot 11, so that the end of the FPC connecting wire and the lock cover 32 are pressed against the terminal 2, and is in close contact with the contact point 2121 on the lower arm 212 of the terminal to realize conductive contact. When the lock cover 3 is opened, the diameter of the area where the cover groove 32 is provided on the pivot shaft 31 decreases, and the pressing force of the pivot shaft 31 on the FPC connection wire is small, and the user can easily pull out the FPC connection wire.

When the lock cover 3 is closed, in order to ensure that the lock cover 3 can be stably closed on the base 1, a positioning card point 34 is provided on both sides of the lock cover 3, and the inner side of the two side walls 14 of the base 1 is provided There is a positioning card slot 18 corresponding to the positioning card point 34 . When the lock cover 3 is closed on the base 1 and listed on the market, the positioning card point 34 just falls into the positioning card slot 18, so as to form a locking position for the lock cover 3 and prevent it from turning over by itself.

Of course, the above descriptions are only specific embodiments of the utility model, and are not intended to limit the implementation scope of the utility model. Should be included in the utility model patent scope.
