Detailed ways:

The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

As shown in FIGS. 1-7 , the present invention is a single-button double-sided contact FPC transfer connector, which includes: a base 1 , a terminal 2 , and a cover 3 .

The base 1 is injection-molded with insulating plastic material, and the left and right end surfaces of the base 1 are provided with a left slot 11 and a right slot 12 respectively, and a plurality of terminal slots 10 connected to the left and right slots 11 and 12 and evenly distributed. The terminal groove 10 runs through the left end face of the base 1 transversely to the right end face, side walls 14 are formed on both ends of the base 1 in the longitudinal direction, and a gap 13 is formed between the two side walls 14 above the position of the left slot 11. The wall 14 defines a pivoting groove 140 pivotally connected to the cover body 3 , and the pivoting groove 140 is a long-waisted groove.

Due to the existence of the notch 13 , the left side of the terminal groove 10 is exposed from the base 1 . As shown in FIG. 2 and FIG. 4 , the starting position of the left part of the terminal slot 10 penetrates downwardly through the bottom surface of the base 1 to form a card slot 101 . The slot 101 is used for matching with the terminal 2 .

As shown in FIG. 5 , the terminal 2 is integrally formed of metal materials, which includes: a left clamping part 21, a right clamping part 22, a connecting part 23 connecting the left and right clamping parts 21, 22, and a The positioning part 24 below 21 and 22, wherein the left clamping part 21 is composed of the upper left contact arm 211 and the lower left contact arm 212, and the right clamping part 22 is composed of the upper right contact arm 221 and the lower right contact arm 222 .

The upper left contact arm 211 is formed with a positioning groove 2110, the upper right contact arm 221 is formed with a bump 2210; the lower left contact arm 212 and the lower right contact arm 222 are respectively shaped with bumps 2120, 2220.

The starting end of the positioning portion 24 extends downward to form a hook 241 ; the end of the positioning portion 24 upwardly forms a positioning protrusion 242 . When the terminal 2 is inserted into the terminal slot 10 , the hook 240 will cooperate with the slot 101 , and the protrusion 242 will cooperate with the corresponding locking point in the terminal slot 10 , so that the terminal 2 and the terminal slot 10 form a snap-fit.

In addition, the upper surface of the upper left contact arm 211 and the right upper contact arm 221 is formed with a positioning bump 25 on the upper surface of the joint position. The positioning protrusions 25 correspond to the corresponding grooves in the terminal slot 10 , and the positioning protrusions ensure that the upper left contact arm 211 and the upper right contact arm 221 of the terminal will not be laterally shifted when the cover body 3 is turned over.

When installing the terminal 2, insert the terminal 2 from the left side of the terminal slot 10, and the terminal 2 passes through the terminal slot 10 until the hook 240 of the terminal 2 is engaged in the slot 101, at this time, the protrusion 242 will be aligned with the terminal slot 10. The corresponding locking points in the terminal groove 10 cooperate, and the positioning protrusions 25 also realize positioning. In this way, the terminal 2 is fixed in the base 1 . Of course, the terminal 2 may also be directly fixed in the base 1 by injection molding in an integral injection molding manner.

After the terminal 2 is assembled on the base 1, the left clamping part 21 of the terminal 2 is exposed on the left side of the terminal groove 10, that is, a notch 13 is formed on the position corresponding to the left slot 11 of the base 1, and a notch 13 is formed in the notch 13 A cover body 3 is provided at the center, and the two ends of the cover body 3 are pivotally connected to the base 1 longitudinally to realize the flipping of the cover body 3 . The specific structure is as follows:

The axial ends of the cover body 3 are provided with pivots 31 corresponding to the pivot grooves 140 . The other side of the cover body 3 opposite to the pivot 31 is formed with a limiting protrusion 33 that interferes with the side wall 14 . In order to facilitate assembly, the end surface of the pivot 31 is formed with a guiding slope. In order to facilitate the rotation of the left cover 3 , a guide slope is formed on the side of the limiting protrusion 33 interfering with the side wall 14 .

Since the pivot joint groove 140 is a long waist-shaped groove, when the cover body 3 is completely opened, since there is no restriction on it by the side wall 14 of the base 1, the cover body 3 has a certain lateral sliding margin, which On the one hand, this design is to facilitate the installation of the cover 3 and the base 1, and on the other hand, after the cover 3 is opened, the lateral sliding margin can reduce the interference with the terminal 2, so that the PFC cable can be easily inserted into the left slot 11 in.

In addition, since the cover body 3 is bound to interfere with the upper left contact arm 211 of the terminal 2 when it rotates, a cover groove 32 is opened on the cover body 3 corresponding to the position of each terminal 2. When the cover body 3 is turned over, the cover groove 32 avoids The upper left contact arm 211 of the terminal 2 enables the cover body 3 to be turned over smoothly.

As shown in Figure 8, when using the present invention, first rotate the cover body 3 to the open position, then insert the two FPC connecting wires 4 from the left and right ends into the left and right slots 11, 12 of the present invention, so that the two FPCs are connected The contact parts of the wire 4 are respectively inserted into the left clamping part 21 and the right clamping part 22 of the terminal 2 , and then the cover body 3 is rotated so as to cover it with the base 1 . Referring to Figures 1 and 7, due to the existence of the cover groove 32, the cover body 3 can be opened or closed smoothly. At the same time, when the cover body 3 is closed on the base 1, the positioning provided on the upper left contact arm 211 The groove 2110 just fits with the partition on the upper cover groove 32 of the cover body 3, and is stuck on the cover body 3. At this time, as the cover body 3 moves from the opened position to the closed position, the upper cover groove 32 of the cover body 3 The partition will constantly generate an upward force on the upper left contact arm 211. Since the upper left contact arm 211 and the upper right contact arm 221 are integrally formed, a leverage effect will be generated. The upper right contact arm 221 of the terminal 2 will use the positioning bump 25 as a The fulcrum produces downward deformation, thereby reducing the clamping space of the right clamping portion 22 , thereby clamping the end of the FPC connecting wire inserted into the right slot 12 . At the same time, the end of the FPC connecting wire inserted into the left slot 11 is clamped together with the cover body 32 by the left clamping portion 11 of the terminal 2 and realizes conductive contact.

When the two FPC data lines 5 need to be separated, the cover body 3 only needs to be lifted, and the clamping force acting on the FPC data lines 4 disappears, and the FPC data lines can be easily pulled out from the connector.

Of course, the above descriptions are only specific embodiments of the present invention, and are not intended to limit the implementation scope of the present invention. All equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention should be included in the The present invention is within the patent scope.
