As shown in fig. 4, corresponding to the first spring piece portion 143 and the second spring piece portion 153, a first placement groove 113 and a second placement groove 114 extend downward from the upper plane of the insulating rubber base 11. The first elastic piece 143 is elastically pressed against the upper surface of the insulating rubber seat 11, and is enclosed together with the first placement groove 113 to form a first hinge cavity 16. The second spring plate 153 is also elastically pressed against the upper plane of the insulating rubber seat 11, and is enclosed by the second spring plate and the second placement groove 114 to form a second hinge cavity 17. The first and second flipping function sections 122 and 123 are hinged in the first and second hinge cavities 16 and 17, respectively (as shown in fig. 20 to 24).
The working principle of the automatic locking structure suitable for the FPC connector is generally as follows: when the locking operation is performed on the FFC flat cable 2, the FFC flat cable 2 is pushed to perform translational movement along the FFC flat cable plugging slot 111, in this process, the first elastic sheet portion 143 and the second elastic sheet portion 153 are forced to perform elastic deformation under the pushing force of the FFC flat cable 2, and then the first clamping portion 144 and the second clamping portion 154 elastically lean against the upper plane of the FFC flat cable 2 and perform relative sliding movement until they are respectively clamped into the first clamping positioning notch 21 and the second clamping positioning notch 22 formed on the FFC flat cable 2, and meanwhile, the connection terminal 13 is conducted with the FFC flat cable 2 to perform signal transmission; when the unlocking operation is performed on the FFC flat cable 2, the operator pulls the main body 121 of the turnover member 12, and at the same time, the first turnover functional portion 122 and the second turnover functional portion 123 disposed thereon perform synchronous rotation along with each other, and because the sections of the two are designed to be long waists, the first fixing member 14 and the second fixing member 15 are elastically deformed in an adaptive manner, and further the first clamping portion 144 and the second clamping portion 154 are driven to move upwards in a displacement manner until the first clamping positioning notch 21 and the second clamping positioning notch 22 are separated from each other, so that the unlocking operation on the FFC flat cable 2 is completed.
By adopting the technical scheme, the invention has the beneficial effects that 1) compared with the traditional turnover FPC connector, the technical scheme disclosed by the invention has the advantages that the structure is simple, the manufacturing and the forming of parts are convenient, and the manufacturing cost is relatively low; 2) The first fixing piece 14 and the second fixing piece 15 can be directly attached and fixed by the insulating rubber seat 11 without reserving a movable space, so that the overall thickness dimension of the FPC connector 1 is effectively reduced, and the layout and design of the assembly space of the FPC connector at the later stage are facilitated; 3) The assembling time of the FPC connector 1 is greatly shortened, and the manufacturing cost is reduced. In the actual operation process, the turnover piece 12 is turned and turned to enable the first fixing piece 14 and the second fixing piece 15 to elastically deform, so that the first clamping portion 144 and the second clamping portion 154 are forced to perform insertion/detachment movement relative to the FFC flat cable 2, and further clamping, fixing and detachment of the FFC flat cable 2 are achieved, and accordingly the installation and detachment speeds of the FFC flat cable 2 are greatly improved.
As a further optimization of the above-described auto-lock structure applied to the FPC connector, the left and right side walls of the main body 121 may further extend outward and be bent downward to form a first lower-extension-limit portion 1211 and a second lower-extension-limit portion 1212 (as shown in fig. 10). A first avoiding groove 115 and a second avoiding groove 116 (as shown in fig. 4) which are matched with the first lower-extension limiting part 1211 and the second lower-extension limiting part 1212 extend downwards from the upper plane of the insulating rubber seat 11. In this way, when the assembly operation of the first fixing member 14, the second fixing member 15 and the insulating base 11 is performed, a portion of the first fixing member can be skillfully sunk in the insulating base 11, thereby further reducing the overall height dimension of the FPC connector 1. The first and second locking portions 144 and 154 lock the first and second locking and positioning notches 21 and 22 by the self weight of the body 121. In addition, the first downward-extending limiting portion 1211 and the second downward-extending limiting portion 1212 can effectively prevent the overturning 12 piece from being "biased", ensure the accuracy of the relative positions of the first overturning functional portion 122 and the second overturning functional portion 123, and prevent the overturning 12 piece from being separated from the first hinge cavity 16 and the second hinge cavity 17 due to unbalanced stress.
As known, the FPC connector 1 is inevitably affected by "vibration" during the actual working process, and is only beneficial to the dead weight of the main body 121 of the turnover member 12 to lock the position of the FFC flat cable 2, which is extremely unstable, and is extremely easy to release, so that the first positioning protruding portion 12111 and the second positioning protruding portion 12121 may be extended outwards from the first downward-extending limiting portion 1211 and the second downward-extending limiting portion 1212, and correspondingly, the first limiting flange 1151 and the second limiting flange 1161 (as shown in fig. 6 and 10) respectively adapted to the first positioning protruding portion 12111 and the second positioning protruding portion 12121 are provided on the side walls of the first avoiding groove 115 and the second avoiding groove 116. Through adopting above-mentioned scheme to set up, can utilize first spacing flange 1151, the spacing flange 1161 of second to realize respectively that the fender to first location bellying 12111, second location bellying 12121 leans on, and then realized first mounting 14, second mounting 15 for the steadiness of plastic rubber seat 11 buckle, stop FFC winding displacement 2 and take place the pine phenomenon because of "vibrations".
In order to ensure that the processes of the first positioning boss 12111 and the second positioning boss 12121 entering or exiting the first limit rib 1151 and the second limit rib 1161 are smoothly performed, and further ensure the assembly and disassembly efficiency of the FFC flat cable 2, the upper and lower sidewalls of the first positioning boss 12111 may be subjected to a beveling process to form a first guide bevel 121111 and a second guide bevel 121112 (as shown in fig. 11), respectively. The upper and lower sidewalls of the first stopper rib 1151 are also chamfered to form a third guiding inclined plane 11511 and a fourth guiding inclined plane 11512 (as shown in fig. 7), respectively. The upper and lower sidewalls of the second positioning boss 12121 are subjected to chamfering processing to form a fifth guide slope 121211, a sixth guide slope 121212, respectively (as shown in fig. 12). The upper and lower sidewalls of the second stop flange 1161 are also beveled to form seventh and eighth guide ramps 11611, 11612 (shown in fig. 8), respectively.
In addition, as a further optimization of the above-described embodiments, the front side walls of the first and second engaging portions 144, 154 may be subjected to a chamfering process to form a ninth guide slope 1441 and a tenth guide slope 1541, respectively (as shown in fig. 17, 19). In this way, in the process of pushing the FFC flat cable 2 to perform the translational movement along the FFC flat cable inserting groove 111, the first clamping portion 144 and the second clamping portion 154 can be automatically lifted under the action of the propping force, so as to automatically slide into the first clamping positioning notch 21 and the second clamping positioning notch 22.
As shown in fig. 15, the connection terminal 13 is constituted by a socket arm 131 and an elastic pressing arm 132. The plugging arm 131 is disposed in the terminal plugging slot 112, and the elastic pressing arm 132 exceeds the upper plane of the insulating rubber seat 11 by 0.1-0.3mm (as shown in fig. 20). In order to avoid the terminal 13 and reduce the overall forming thickness of the flip member 12 as much as possible, a series of third avoiding grooves 1213 may also extend upwardly from the lower side wall of the main body 121 of the flip member 12, corresponding to the terminal 13. The third escape recess 1213 penetrates in the front-rear direction (as shown in fig. 13). The flip 12 also includes a bearing arm 124 for ensuring structural strength thereof. The bearing arm 124 is connected between the left and right sidewalls of the front end of each of the third escape recesses 1213 (as shown in fig. 14). The resilient pressure arm 132 is disposed within the third relief recess 1213 and resiliently presses against the bearing arm 124 (as shown in fig. 26, 27, 29).
The first fixing element 14, the second fixing element 15 can be fixed to the insulating rubber mount 11 in a number of ways, but a preferred way is proposed here, in particular as follows: a first fixing groove 117 and a second fixing groove 118 for respectively placing and limiting the first fixing part 141 and the second fixing part 151 extend downwards from the upper plane of the insulating rubber seat 11. At least 2 first clamping arms 1411 are extended downwards from the lower plane of the first fixing portion 141, and correspondingly, first plugging notches 1171 adapted to the first clamping arms 1411 are extended downwards from the bottom wall of the first fixing groove 117. At least 2 second clamping arms 1511 are extended downwards from the lower plane of the second fixing portion 151, and correspondingly, a second insertion notch 1181 adapted to the second clamping arms 1511 is extended downwards from the bottom wall of the second fixing groove 118. At least 1 third clamping arm 1412 extends from the outer side surface of the first fixing portion 141, and correspondingly, a third plugging notch 1172 adapted to the third clamping arm 1412 extends from the side wall of the first fixing groove 117. At least 1 fourth clamping arm 1512 extends outwards from the outer side surface of the second fixing portion 151, and correspondingly, a fourth inserting notch 1182 (shown in fig. 4-6 and 16-19) adapted to the fourth clamping arm 1512 extends outwards from the side wall of the second fixing groove 118. In this way, the first fixing portion 141 and the second fixing portion 151 are fastened to the insulating rubber base 11, so as to limit the displacement movement along the height direction. While the presence of the third and fourth snap arms 1412, 1512 defines the displacement movement of the first and second fixtures 14, 15 in the front-rear direction. By adopting the technical scheme, the fixing reliability of the first fixing piece 14, the second fixing piece 15 and the insulating rubber seat 11 is ensured, and the time period required for installing the first fixing piece 14 and the second fixing piece 15 is effectively reduced.
