Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an FPC male connector. Background Technology

[0002] Connectors are a component that electronic engineers frequently encounter. Their function is to bridge the gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic devices, and various types of connectors exist depending on the application, frequency, power, and application environment. Currently, existing rear-hinged FPCs with double-sided contact function have the advantages of simple operation of connector cables, saving time and space. However, in actual use, due to the small spacing between the terminals of the double-sided contact connectors, it is easy to cause difficulty in inserting connector cables and misalignment of gold fingers. Therefore, an FPC male connector is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an FPC male connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an FPC male connector, comprising a substrate and a flip cover, wherein the flip cover is movably disposed at one end away from the substrate insertion interface; Several linearly arranged I-shaped conductive terminals are disposed within the connector; The auxiliary insertion mechanism includes a rectangular frame that is horizontally slidably disposed within the substrate insertion interface, used to open the conductive terminal insertion end; The rectangular frame is fixedly connected to both ends with connecting seats. A positioning block for positioning the soft board is vertically slidably connected inside the connecting seat. An opening corresponding to the positioning block is opened on the surface of the rectangular frame. A pressing strip connected to the positioning block is provided on the top of the connecting seat.

[0005] As a preferred embodiment, the substrate surface is provided with a limiting groove that is slidably connected to the connecting seat, the inner wall of the limiting groove is provided with a guide groove that is adapted to the side of the connecting seat, and the side of the connecting seat is fixedly connected with a slider that is horizontally limited and slidable with the guide groove.

[0006] As a preferred embodiment, the connecting seat has a cavity for vertical movement of the positioning block. The inner wall of the cavity of the connecting seat is fixedly connected to symmetrically arranged connecting blocks. The surface of the connecting blocks is fixedly connected to a connecting rod, and a spring is sleeved on the connecting rod for elastic reset of the positioning block.

[0007] As a preferred embodiment, the positioning block has guide grooves on both sides of its bottom, and the connecting rod passes through the guide grooves and slides vertically therewith.

[0008] As a preferred embodiment, the two ends of the pressing strip are fixedly connected to connecting pieces that pass through the connecting seat and are connected to the positioning block. The connecting seat has an opening groove on the opposite side that matches the connecting piece and communicates with the guide groove.

[0009] As a preferred embodiment, the connection between the flip cover and the substrate is provided with an elastic hinge structure, and the outer side of the flip cover is provided with anti-slip texture.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting an auxiliary cable insertion mechanism, uses a sliding rectangular frame to drive the flexible flat cable insertion end. By actively expanding the closely arranged I-shaped conductive terminals, the gap between the inserted conductive terminal interfaces is widened, which can avoid the problems of misalignment and scratching of the gold fingers of the flexible flat cable caused by the small terminal spacing. This greatly reduces the difficulty of cable insertion and enables quick assembly. Compared with the existing rear-hinged FPC type, cable insertion is simple and quick, and has the advantage of good guidance. This invention allows the positioning block to be driven downward to fix the flexible cable by pressing the pressing strip, thus preventing the cable from shifting during movement. With the guidance of the substrate limiting groove and the connecting seat slider, the rectangular frame can be moved smoothly along a straight line without jamming or shifting, which can significantly improve the insertion accuracy.

[0013] The present invention will be further described below with reference to the embodiments.

[0014] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0015] Please see Figures 1-4 This utility model provides an FPC male connector, comprising: The substrate 1 and the flip cover 2 are movably disposed at the end away from the insertion interface of the substrate 1; Several linearly arranged I-shaped conductive terminals 3 are provided in the plug interface. One end of the conductive terminal 3 extends to the interface to form a contact part, and the other end is used for electrical connection with external circuit. The auxiliary insertion mechanism includes a rectangular frame 4 that is horizontally slidably disposed within the insertion interface of the substrate 1, for supporting the insertion end of the conductive terminal 3; The rectangular frame 4 is fixedly connected to the two ends of the connecting seat 5. The connecting seat 5 is vertically slidably connected to the positioning block 6 for positioning the soft board. The rectangular frame 4 has an opening corresponding to the positioning block 6. The top of the connecting seat 5 is provided with a pressing strip 7 that is connected to the positioning block 6.

[0016] When the flexible flat cable is inserted into the rectangular frame 4, the pressing strip 7 is pushed downwards in the vertical direction to press it in place. This causes the positioning block 6 to move downwards and fix the insertion part of the flexible flat cable inside the rectangular frame 4. The connecting seat 5 is pushed to move towards the flip cover 2. When the rectangular frame 4 moves, the insertion end of the I-shaped conductive terminal 3 is opened to ensure that the flexible flat cable can be accurately inserted into the gap between the conductive terminals 3, avoiding the problem of wire misalignment caused by the terminal spacing being too small.

[0017] The substrate 1 has a limiting groove 14 that is slidably connected to the connector 5. The inner wall of the limiting groove 14 has a guide groove 8 that is adapted to the side of the connector 5. The side of the connector 5 is fixedly connected to a slider 9 that is horizontally limited and slidable with the guide groove 8. This ensures that the rectangular frame 4 moves smoothly along a straight line in the interface of the substrate 1, and avoids the rectangular frame of the connector 5 from shifting or getting stuck due to the application of vertical force to the pressing strip 7. This effectively improves the smoothness and accuracy of the soft flat cable insertion process. The connecting seat 5 has a cavity for the positioning block 6 to move vertically. The inner wall of the cavity of the connecting seat 5 is fixedly connected to symmetrically arranged connecting blocks 10. The surface of the connecting block 10 is fixedly connected to a connecting rod 11, and a spring 12 is sleeved on the connecting rod 11. When the rectangular frame 4 moves the flexible flat cable to the designated position, the pressing strip 7 is released, and the positioning block 6 automatically resets under the action of the spring 12 inside the connecting seat 5, releasing the fixation of the flexible flat cable. At this time, the flip cover 2 can be flipped down and fastened to the base plate 1. The flexible flat cable is tightly pressed into the contact part of the conductive terminal 3 by the elastic pressing plate inside the flip cover 2, ensuring a stable electrical connection between the two.

[0018] The bottom of the positioning block 6 has guide grooves 13 on both sides. The connecting rod 11 passes through the guide grooves 13 and slides vertically therewith. The slider 9 slides against the inner wall of the guide grooves 13, ensuring that the rectangular frame 4 moves smoothly along a straight line within the interface of the base plate 1. This prevents the auxiliary cable insertion mechanism from shifting or getting stuck, and improves the smoothness and accuracy of the flexible flat cable insertion process. The two ends of the pressing strip 7 are fixedly connected with connecting pieces that pass through the connecting seat 5 and are connected to the positioning block 6. The connecting seat 5 has an opening groove on the opposite side that matches the connecting piece and communicates with the guide groove 8.

[0019] The inner side of the flip cover 2 is provided with a pressing part corresponding to the position of the conductive terminal 3. When the flip cover 2 is fastened, the pressing part pushes the conductive terminal 3 to deform. The contact parts at the upper and lower ends of the conductive terminal 3 are pressed with the FPC cable insertion end, which effectively prevents poor contact. The conductive terminal 3 is made of beryllium copper, which has good conductivity and elasticity, and can effectively improve the service life of the connector. The connection between the flip cover 2 and the substrate 1 is provided with an elastic hinge structure. After the flip cover 2 is fastened, the gap between it and the substrate 1 is ≤0.1mm, which can prevent external impurities from entering. The flip cover 2 maintains a stable rotation trajectory during the fastening and opening process, while providing appropriate fastening force to ensure that the FPC cable will not loosen or fall off during use. The outer side of the flip cover 2 is provided with anti-slip texture to increase friction during operation and facilitate the opening and closing of the flip cover 2.

[0020] The working principle and usage process of this utility model are as follows: In actual application, first flip the cover 2 upward to the maximum angle, align the FPC flexible flat cable insertion end with the opening of the rectangular frame 4, and ensure that the gold finger area of ​​the flexible flat cable faces the conductive terminal 3.

[0021] Press the pressing strip 7, and the positioning block 6 slides down along the cavity inside the connecting seat 5 under the guidance of the connecting rod 11 until its bottom passes through the opening of the rectangular frame 4 and presses against the surface of the flexible cable, thus achieving the initial fixation of the flexible cable.

[0022] Push the connector 5, and the slider 9 on the side of the connector 5 will slide smoothly along the guide groove 8, driving the rectangular frame 4 to move into the interface of the base plate 1.

[0023] The frame structure of the rectangular frame 4 will spread out the insertion end of the originally closely arranged I-shaped conductive terminals 3, forming a larger insertion gap, so as to avoid misalignment or rubbing between the gold fingers and the conductive terminals 3 when the flexible flat cable is inserted. When the rectangular frame 4 moves to the front of the contact part of the conductive terminal 3, the pressing strip 7 is released, and the positioning block 6 returns to its original position under the elastic restoring force of the spring 12, thus relieving the pressure on the flexible cable. Flip the cover 2 downwards. The cover 2 is tightly fastened to the substrate 1 by the elastic hinge structure. The pressing part on its inner side will further press the flexible flat cable onto the conductive terminal 3, so that the contact parts of the conductive terminal 3 arranged on the top and bottom are in close contact with the insertion end of the flexible flat cable, ensuring that a stable electrical connection is formed between the two. It enables convenient operation and precise positioning throughout the entire insertion process, effectively solving the problems of difficult insertion, easy damage to terminals and ribbon cables in traditional FPC connectors, and significantly improving assembly efficiency and connection reliability.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
