Detailed Description
In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The present invention will be described in detail with reference to the following embodiments, and fig. 3 shows a perspective view (the FFC cable is in a non-engaging state) of the flip-chip FPC connector assembly according to the present invention, which is composed of the FPC connector 1, the PCB 2 and the FFC cable 3. The FFC flat cable 3 is inserted into the FPC connector 1 and integrally fixed on the PCB 2.
Fig. 2 shows an exploded view of the flip-chip type FPC connector assembly according to the present invention, and it can be seen that the FPC connector 1 is mainly composed of several parts, such as an insulating rubber base 11 (shown in fig. 10), a flip-chip 12 (shown in fig. 11 and 12), and a connection terminal 13 (shown in fig. 13). The insulating rubber base 11 is provided with an FFC flat cable inserting groove 111 therein, and extends from front to back for inserting the FFC flat cable 3. A series of terminal insertion grooves 112 are uniformly formed along the left and right directions of the FFC bus bar insertion groove 111 for inserting and fixing the connection terminals 13. It should be emphasized that the connecting terminal 13 has an "X-shape" structure, and is formed by connecting an upper cantilever 131, a lower cantilever 132 and a middle connecting arm 133. First and second inwardly extending protrusions 1311 and 1321 extend from the front free ends of the upper and lower cantilevers 131 and 132, respectively, and are disposed opposite to each other. The FFC bus 3 is arranged right in front of the middle connection arm 133, and is sandwiched between the upper suspension arm 131 and the lower suspension arm 132. The turnover part 12 is hinged to the insulating rubber base 11, disposed right behind the middle connection arm 133, and also sandwiched between the upper suspension arm 131 and the lower suspension arm 132.
In the actual operation process, when the FFC flat cable 3 needs to be locked, the first inward extending protrusion 1311 can be closed relative to the second inward extending protrusion 1321 by pulling and turning the turning piece 12 clockwise, so that the FFC flat cable 3 is clamped and fixed by the connecting terminal 13 (as shown in fig. 6, 7 and 8); when the FFC flat cable 3 needs to be unlocked, the first inward extending protrusion 1311 can be separated from the second inward extending protrusion 1321 by pulling and turning the turning piece 12 in the counterclockwise direction, so that the connection terminal 13 is separated from the FFC flat cable 3, and the FFC flat cable 3 is unlocked (as shown in fig. 3, 4 and 5).
As can be seen from the above description, the structural form of the flip 12 itself is particularly important for the normal execution of the locking and unlocking process of the FFC bus 3, and therefore, a preferred design form of the flip 12 is proposed in the present invention, which is as follows: an avoiding groove 121 extends inward from the front side wall of the flip member 12 at a position corresponding to the terminal 13, and a force-bearing arm 122 for clamping the upper arm 131 and the lower arm 132 is additionally formed right in front of the avoiding groove 121 (see fig. 11 and 12). The height dimension h of the force-bearing arm 122 is greater than the thickness dimension t. Therefore, on the premise of ensuring the smooth execution of the locking and unlocking processes of the FFC flat cable 3, the design structure is simplified to the maximum extent, so as to reduce the molding difficulty and the manufacturing cost.
As is known, in the whole life process of the FPC connector 1, the locking/unlocking operation of the FFC bus bar 3 needs to be repeatedly performed for many times, and in the past, the outer surface of the force-bearing arm 122 is inevitably worn, so that the fitting accuracy with the connection terminal 13 is affected, and the locking stability and reliability of the FFC bus bar 3 are affected. In view of this, a wear-resistant coating (not shown in the figure) may be further disposed on the side wall of the force-bearing arm 122, which is in pre-contact with the upper cantilever 131 and the lower cantilever 132, so as to effectively reduce the relative friction coefficient between the force-bearing arm 122 and the connection terminal 13, and thus, on one hand, the wear rate of the force-bearing arm 122 can be reduced to a certain extent, so as to ensure the precision of the fit between the force-bearing arm 122 and the connection terminal 13; on the other hand, the turnover piece 12 is convenient to pull, and the operation difficulty is reduced.
In order to ensure the connection reliability of the FPC connector 1 and the PCB 2, an interposer 14 (as shown in fig. 2, 3, 6, 10, and 14) may be further added to the FPC connector. A through slot 113 matched with the shape of the plug-in 14 extends backwards along the front side wall of the insulating rubber seat 11. The number of the plug-ins 14 is set to 2, and correspondingly, the number of the through slots 113 is also set to 2, and the through slots are symmetrically distributed on the left side and the right side of the insulating rubber base 11. With respect to the above-described insert 14, a fixing piece 21 is provided on the upper plane of the PCB board 2 (as shown in fig. 15). When the FPC connector 1 is put in place with respect to the PCB 2, the plug 14 passes through the through groove 113 in the front-rear direction, and then, the lower end portion thereof is fixed by soldering to the fixing piece 21.
It should be noted that various designs can be adopted to realize the hinge joint of the turnover part 12 and the insulating rubber seat 11 according to practical situations, however, an optimal design is recommended in the present embodiment, as shown in fig. 17, which is as follows: a placing sink groove 114 (shown in fig. 10) matched with the turnover part 12 extends along the front of the rear side wall of the insulating rubber seat 11. Behind the middle link arm 133, a first limit projection 1322 and a second limit projection 1323 (shown in fig. 13) extend along the top wall of the lower suspension arm 132. The insert 14 is inserted into the placement sinking groove 114 and abuts against the left and right side walls of the placement sinking groove 114, respectively, and the bottom wall of the placement sinking groove 114 is used to form the hinge cavity 115 (as shown in fig. 9), and correspondingly, the force-bearing arm 122 is disposed between the first limiting projection 1322 and the second limiting projection 1323 (as shown in fig. 4, 5, 7 and 8). Hinge protrusions 123 (shown in fig. 11 and 12) are extended from the left and right side walls of the flip member 12 to match with the hinge cavities 115. Therefore, on one hand, the turnover part 12 and the insulating rubber seat 11 have simpler design structures, and are beneficial to manufacturing and molding; on the other hand, the turnover piece 12 is convenient to assemble on the insulating rubber base 11, and the assembly application is reduced; more importantly, through adopting above-mentioned technical scheme to set up, in the process of actually tearing open, adorning FFC winding displacement 3, upset 12 is difficult for deviating from in the insulating rubber seat 11, ensures both articulated reliability of connecting.
In the above technical solution, the FFC flat cable 3 is locked by the elastic pressing force of the connection terminal 13, which not only greatly improves the mounting and dismounting speed of the FFC flat cable 3, but also realizes the on/off of the connection terminal 13 to the conductor on the FFC flat cable 3, effectively optimizes the design structure of the FPC connector 1, but also has the following disadvantages: when the FFC flat cable 3 is subjected to a pulling force, the FFC flat cable 3 is easily separated from the common clamping of the first inward extending protrusion 1311 and the second inward extending protrusion 1321, so that the FFC flat cable 3 is loosened. In view of this, as a further optimization of the above technical solution, with respect to the positions of the two outermost terminals 13, the clamping positioning grooves 31 are respectively extended inward from the left and right side walls of the FFC flat cable 3 for the first inward extending protrusion 1311 and the second inward extending protrusion 1321 to be inserted, so as to realize the clamping connection of the FFC flat cable 3 (as shown in fig. 5, 8 and 16).
In order to improve the structural strength of the clamping positioning groove 31, prevent the clamping positioning groove from being pulled apart, and ensure the connection stability of the FFC flat cable 3, a reinforcing plate 32 may be additionally added to the FFC flat cable 3. The reinforcing plate 32 is abutted and fixed to the lower plane of the FFC flat cable 3. The snap-fit positioning groove 31 is opened on the reinforcing plate 32 and continues to extend upward until it passes through the FFC flat cable 3 (as shown in FIG. 16).
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
