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 of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In order to facilitate the technical solution disclosed by the present invention to be fully understood by those skilled in the art, the following detailed description is made in combination with the specific embodiments, fig. 1 and fig. 2 respectively show a schematic perspective view and a top view of the FPC connector of the present invention, it can be known that the FPC connector mainly comprises an upper rubber base 1, a lower rubber base 2, an FFC flexible flat cable 3, a connecting terminal 4, and the like, wherein the upper rubber base 1 and the lower rubber base 2 are detachably connected. The number of the connecting terminals 4 is set to be a plurality, and the connecting terminals are arranged between the upper rubber base 1 and the lower rubber base 2 side by side, and are inserted and fixed on the lower rubber base 2 to elastically compress and conduct the FFC flexible flat cable 3 (as shown in fig. 3 and 4).
In consideration of convenience in mounting and dismounting the FFC flexible flat cable 3, the structure of the FPC connector may be further refined as follows: the upper rubber base 1 comprises 2 hinge shafts 11 symmetrically fixed at the rear ends of the left and right side walls of the upper rubber base, and further comprises 2 clamping grooves 12 symmetrically arranged at the front ends of the left and right side walls of the upper rubber base 1 (as shown in fig. 8), correspondingly, hinge holes 21 matched with the hinge shafts 11 are formed at the rear ends of the left and right side walls of the lower rubber base 2, and hook protrusions 22 matched with the clamping grooves 12 are arranged at the front ends of the left and right side walls of the lower rubber base (as shown in fig. 9), so that the upper rubber base 1 and the lower rubber base 2 are buckled and connected.
As a further refinement of the above technical solution, the upper rubber base 1 and the lower rubber base 2 are all integrally injection-molded parts, i.e., the hinge shaft 11, the slot 12, the hinge hole 21 and the hooking protrusion 22 are directly molded (as shown in fig. 8 and 9), thereby avoiding post-assembly and secondary processing procedures and effectively reducing production and manufacturing costs thereof.
It should be emphasized that fig. 5 shows a schematic perspective view of a first embodiment of the connection terminal with chip grooves in the FPC connector according to the present invention, which is formed by stamping and bending a sheet metal body, and is composed of an insertion section 41, a bending transition section 42 and a conduction section 43, and connected in sequence along a direction from left to right. The conducting section 43 includes an FFC bus cable supporting arm 431 and an FFC bus cable elastic pressing arm 432 disposed above and opposite to the FFC bus cable supporting arm 431, and the FFC flexible bus cable 3 is elastically sandwiched therebetween. At least one chip groove 4311 is formed on the upper plane of the FFC bus bar support arm 431. Therefore, scraping and grinding dust generated in the inserting process of the FFC flexible flat cable 3 can be conveniently and timely contained, the FFC flexible flat cable is prevented from accumulating on the FFC flat cable supporting arm 431, good conductivity between the FFC flexible flat cable and the FFC flexible flat cable 3 is ensured, and stability and reliability of signal transmission are ensured
Generally, the chip pocket 4311 is preferably formed by punching a forming punch, so that the forming process is simplified as much as possible and the manufacturing cost is reduced.
As a further refinement of the structure of the connection terminal 4, the chip grooves 4311 are preferably designed as strip-shaped grooves 43111, and extend perpendicular to the length direction of the FFC flexible flat cable support arms 431, that is, in accordance with the insertion direction of the FFC flexible flat cable 3 (as shown in fig. 5), so as to facilitate the scraping and grinding dust collection process.

Of course, an inclined guiding portion 4322 may also be extended along the arc-shaped conducting portion 4321 and the two portions are in tangential transition (as shown in fig. 6), so as to provide a certain guiding function for the insertion process of the FFC flexible flat cable 3 and prevent the occurrence of the scraping damage phenomenon.
In addition, in view of improving the elasticity of the FFC flat cable elastic pressing arm 432, the width value thereof is gradually decreased along the length extending direction (as shown in fig. 5), so that the FFC flat cable 3 is always in an elastic contact state, thereby further reducing the risk of scratching the FFC flat cable 3 and ensuring the stability of signal transmission.
Fig. 7 is a schematic perspective view of a second embodiment of the connection terminal having a chip groove in the FPC connector of the present invention, which is different from the first embodiment in that: the chip grooves 4311 are designed as strip-shaped through grooves 43112, and extend perpendicularly to the length direction of the FFC bus bar support arms 431, so that the scraping abrasive dusts can flow out toward the side walls of the FFC bus bar support arms 431, and the practical application effect is prevented from being affected by the scraping abrasive dusts.
Generally, in the injection molding stage of the upper rubber base 1, the plug section 41 of the connecting terminal 4 is pre-placed in the cavity of the injection mold to form a gapless assembly. In addition, after molding, the inserting section 41 is also acted by the plastic wrapping force, so that the combination firmness of the wiring terminal 4 and the gluing seat 1 is further enhanced.
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. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
