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 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 embodiments are combined to further explain the contents of the present invention in detail, fig. 1, fig. 2 and fig. 3 respectively show the three-dimensional schematic diagram, the top view and the a-a cross-sectional view of the FPC connector of the present invention, it can be known that the FPC connector mainly comprises several parts, such as the upper rubber base 1, the lower rubber base 2, the FFC flexible flat cable 3 and the connecting terminal 4, wherein the upper rubber base 1 and the lower rubber base 2 are connected in a detachable manner. The number of the wiring terminals 4 is set to be a plurality of, and the wiring terminals are arranged between the upper rubber base 1 and the lower rubber base 2 side by side, and are inserted into and fixed on the lower rubber base 2 so as to elastically compress and conduct the FFC flexible flat cable 3.
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. 7), 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. 8), 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. 7 and 8), thereby avoiding post-assembly and secondary processing procedures and effectively reducing production and manufacturing costs thereof.
It should be emphasized that fig. 4 shows a schematic perspective view of a first embodiment of the connecting terminal with high resilience in the FPC connector of 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 functional section 43, and connected in sequence along the direction from left to right. The functional segment 43 includes a connecting portion 431 and a conducting portion 432. The connection portion 431 is bent in a serpentine shape, and at least one bending resilient unit 4311 is disposed along a length direction thereof. Thus, the extension length of the connecting portion 431 is effectively increased, the overall rigidity of the connecting terminal 4 is reduced to a certain extent, and the connecting terminal and the FFC flexible flat cable 3 have a good elastic contact state, so that the FFC flexible flat cable 3 is prevented from being damaged by pressure in the insertion process, and the reliability and stability of signal transmission are ensured.
Generally, practical experiments prove that the bending radius of the bending resilient unit 4311 is not less than 2 times the wall thickness of the connecting portion 431, so as to achieve better practical application effect.
In addition, in order to further improve the elasticity of the terminal 4 itself, the following arrangement may be made: along the length extension direction, the width of the functional section 43 is gradually decreased (as shown in fig. 4), so that the functional section and the FFC flexible flat cable 3 are kept in a better elastic contact state, the risk of scratching the FFC flexible flat cable 3 is further reduced, and the stability of signal transmission is ensured.
It is known that the conduction portion 432 is used to realize reliable conduction with the FFC flexible flat cable 3. Of course, an inclined guiding portion 433 may also be extended along the conducting portion 432, and the two portions are in tangential transition (as shown in fig. 5), so as to play a certain guiding role in the insertion process of the FFC flexible flat cable 3, and prevent the occurrence of the scraping damage phenomenon.
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.
Fig. 6 is a front view of a second embodiment of the connecting terminal with high resilience in the FPC connector of the present invention, which is different from the first embodiment in that: a plurality of conduction bumps 4321 are uniformly distributed on the conduction part 432 just corresponding to the FFC flexible flat cable 3, so that the FFC flexible flat cable 3 is effectively prevented from being damaged due to instantaneous contact high voltage, the conduction stability of the FFC flexible flat cable 3 is improved, and good signal transmission is ensured.
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.
