Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an FPC cable anti-detachment connector. Background Technology

[0002] With the continuous advancement of surface mount technology, flexible printed circuit boards (FFC cables) and their compatible flexible circuit board connectors have provided key technical support for the miniaturization and thinning of many consumer electronics products.

[0003] After extensive searching, the announcement number CN208489391U discloses an FPC connector in which the insulating cover and the insulating shell are rotatably connected by a connecting terminal, without the need for a separate rotating shaft. When the insulating cover is closed, the semi-circular hook of the upper arm of the connecting terminal hooks the insulating cover and presses the insulating cover tightly against the end face of the insulating shell under the action of elasticity.

[0004] In existing technologies, when the device is in use, the semi-circular hook of the upper arm of the connecting terminal is used to hook the insulating cover and press the insulating cover tightly against the end face of the insulating shell under the action of elasticity. However, when the FPC cable sheath is thick, there is a possibility that the insulating cover may be pushed open, which may cause the FPC cable to loosen or fall off. Therefore, an FPC cable anti-detachment connector is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment connector for FPC cables, which has the advantage of clamping and positioning the installed FPC cables to prevent them from loosening and falling off. It solves the problem that when the insulation cover is thick, the FPC cable is difficult to clamp and position effectively, which leads to the FPC cable loosening and falling off.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an FPC cable anti-disconnection connector, including an insulating housing, an insulating cover being movably inserted into one side of the insulating housing, and second mounting holes being provided at both the front and rear ends of one side of the insulating housing, with a second nut post embedded in each of the two second mounting holes;

[0007] The insulating cover has first mounting holes at both the front and rear ends on one side, and first nut posts are embedded in both first mounting holes. Locking screws are threaded into both first nut posts.

[0008] Both of the aforementioned captive screws have one end passing through the first nut post and threadedly connected to the second nut post.

[0009] Preferably, the insulating housing has equidistant through-slots on its inner side, within which connecting terminals are movably inserted. Through-grounding holes are respectively formed on the insulating housing at both ends of the through-slots, within which grounding plates are movably inserted. The equidistant through-slots on the inner side of the insulating housing provide stable space for the connecting terminals, ensuring accurate contact between the terminals and the gold fingers of the FPC cable. This design not only improves connection stability but also facilitates the installation and removal of the connecting terminals. The grounding holes and the insertion of the grounding plates provide additional grounding protection for the connector. This helps reduce electromagnetic interference and improve signal transmission quality. Simultaneously, the design of the grounding plates ensures the safety of the connector during use.

[0010] Preferably, the connecting terminal adopts a sheet-like structure design, with a barb at the end of the connecting terminal that inserts into the communicating groove, and the barb on the connecting terminal passes through the first through hole. The sheet-like structure design of the connecting terminal makes it thinner and easier to install. Simultaneously, the barb at the end of the connecting terminal that inserts into the communicating groove not only enhances the connection strength between the connecting terminal and the insulating housing but also prevents the connecting terminal from accidentally falling off during use.

[0011] Preferably, one end of the grounding plate inserted into the grounding socket is positioned above the second through hole, and the thickness of the grounding plate matches the width of the second through hole. This design ensures that the grounding plate can be effectively compressed when the insulating cover is closed, thereby improving grounding reliability. Simultaneously, the size design of the grounding plate also avoids interference between it and the insulating cover or insulating shell.

[0012] Preferably, the insulating cover can rotate 90 degrees along the top of one side of the grounding plate through the second through hole, and a mounting groove is provided on one side of the lower end face of the insulating cover, in which an anti-slip pad is fixedly installed. This design, allowing the insulating cover to rotate 90 degrees along the top of one side of the grounding plate through the second through hole, allows for easy opening and closing. Simultaneously, the mounting groove on one side of the lower end face of the insulating cover provides space for fixing the anti-slip pad. This design not only enhances the friction between the insulating cover and the FFC cable but also improves the stability of the connection.

[0013] Preferably, the anti-slip pad does not contact the bottom inner side of the insulating housing, and an FFC cable is movably inserted within the gap, with the width of the FFC cable matching the width of the inner side of the insulating housing. This design, where the anti-slip pad does not contact the bottom inner side of the insulating housing and the FFC cable is movably inserted within the gap, ensures that the FFC cable is effectively clamped and positioned within the connector. Simultaneously, the material and structural design of the anti-slip pad also increases the friction between it and the FFC cable, thereby preventing the FFC cable from loosening or falling off during use. Furthermore, the design of the FFC cable width matching the width of the inner side of the insulating housing also ensures the stability and reliability of the connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this utility model, an insulating cover is movably inserted into one side of the insulating shell. The insulating shell has second mounting holes at both the front and rear ends, with second nut posts inside. The insulating cover has first mounting holes at both the front and rear ends, with first nut posts inside. The first nut posts contain lock-on screws, which pass through the first nut posts and are threadedly connected to the second nut posts.

[0016] The insulating cover is fixed to the insulating housing with a lock-on screw, providing additional pressure. The lower end face of the insulating cover has a mounting groove with an anti-slip pad inside, which increases the friction with the FPC cable. The anti-slip pad does not contact the bottom inside the insulating housing, ensuring that the FPC cable can be effectively clamped.

[0017] By using a lock-on screw threaded through the first and second nut posts, additional pressure is applied to the insulating gland. An anti-slip pad at the lower end of the insulating gland increases friction with the FPC cable. This clamping and positioning mechanism ensures the FPC cable is effectively held, preventing loosening or detachment. Therefore, it solves the problem of the insulating gland being unable to effectively clamp and position the FPC cable when its sheath is thick, thus preventing the cable from loosening and detaching.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: an FPC cable anti-disconnection connector, including an insulating shell 2, an insulating cover 1 is movably inserted into one side of the insulating shell 2, and second mounting holes 25 are provided at both the front and rear ends of one side of the insulating shell 2, and a second nut post 251 is embedded in each of the two second mounting holes 25.

[0026] The front and rear ends of one side of the insulating cover 1 are provided with first mounting holes 13, and first nut posts 131 are embedded in both first mounting holes 13. Unremovable screws 132 are threaded into both first nut posts 131.

[0027] One end of each of the two captive screws 132 passes through the first nut post 131 and is threadedly connected to the second nut post 251.

[0028] Specifically, an insulating cover 1 is movably inserted into one side of the insulating housing 2. The insulating housing 2 has second mounting holes 25 at both ends, with second nut posts 251 inside. The insulating cover 1 has first mounting holes 13 at both ends, with first nut posts 131 inside. The first nut posts 131 have captive screws 132 inside. The captive screws 132 pass through the first nut posts 131 and are threadedly connected to the second nut posts 251.

[0029] The insulating cover 1 is fixed to the insulating housing 2 by a captive screw 132, providing additional pressure. The lower end face of the insulating cover 1 has a mounting groove 14 with an anti-slip pad 141 inside, which increases the friction with the FPC cable. The anti-slip pad 141 does not contact the bottom of the inner side of the insulating housing 2, ensuring that the FPC cable can be effectively clamped.

[0030] The retaining screw 132, threaded through the first nut post 131 and connected to the second nut post 251, provides additional pressure to the insulating cover 1. The anti-slip pad 141 at the lower end of the insulating cover 1 increases friction with the FPC cable. Due to this clamping and positioning mechanism, the FPC cable is effectively clamped, preventing loosening or detachment. Therefore, this solves the problem of the insulating cover being unable to effectively clamp and position the FPC cable when its sheath is thick, thus preventing the FPC cable from loosening and detaching.

[0031] Example 2

[0032] To ensure the safety of the insulating housing during use, such as Figure 4 As shown, in this embodiment, through-type connecting slots 23 are equidistantly opened on the inner side of the insulating housing 2. Connecting terminals 21 are movably inserted into the connecting slots 23. Through-type grounding sockets 24 are respectively opened on the front and rear ends of the insulating housing 2 at the connecting slots 23, and grounding plates 22 are movably inserted into the grounding sockets 24. The through-type connecting slots 23 equidistantly opened on the inner side of the insulating housing 2 provide stable movement space for the connecting terminals 21, ensuring that the connecting terminals 21 can accurately contact the gold fingers of the FPC cable. This design not only improves the stability of the connection but also facilitates the installation and removal of the connecting terminals 21. The opening of the grounding sockets 24 and the insertion of the grounding plates 22 provide additional grounding protection for the connector. This helps reduce electromagnetic interference and improve the quality of signal transmission. At the same time, the design of the grounding plates 22 also ensures the safety of the connector during use.

[0033] Example 3

[0034] To ensure the stability of the various components mounted on the insulating housing during use, such as Figure 2 , Figure 3 Figure 4 As shown, in this embodiment, the connecting terminal 21 adopts a sheet-like structure design. One end of the connecting terminal 21 that inserts into the communicating groove 23 is provided with a barb, which passes through the first through hole 11. The sheet-like structure design of the connecting terminal 21 makes it thinner and easier to install. Simultaneously, the barb at the end of the connecting terminal 21 that inserts into the communicating groove 23 not only enhances the connection strength between the connecting terminal 21 and the insulating housing 2, but also prevents the connecting terminal 21 from accidentally falling off during use.

[0035] Furthermore, one end of the grounding piece 22 inserted into the grounding socket 24 is positioned above the second through hole 12, and the thickness of the grounding piece 22 matches the width of the second through hole 12. In this design, one end of the grounding piece 22 inserted into the grounding socket 24 is positioned above the second through hole 12, and its thickness matches the width of the second through hole 12. This design ensures that the grounding piece 22 can be effectively compressed when the insulating cover 1 is closed, thereby improving the reliability of grounding. At the same time, the size design of the grounding piece 22 also avoids interference between it and the insulating cover 1 or the insulating housing 2.

[0036] Furthermore, the insulating cover 1 can rotate 90 degrees along the top of one side of the grounding plate 22 through the second through hole 12. A mounting groove 14 is provided on one side of the lower end face of the insulating cover 1, and an anti-slip pad 141 is fixedly installed in the mounting groove 14. The design of the insulating cover 1 being able to rotate 90 degrees along the top of one side of the grounding plate 22 through the second through hole 12 allows the insulating cover 1 to be easily opened and closed. At the same time, the mounting groove 14 on one side of the lower end face of the insulating cover 1 provides space for fixing the anti-slip pad 141. This design not only enhances the friction between the insulating cover 1 and the FFC cable but also improves the stability of the connection.

[0037] Furthermore, the anti-slip pad 141 does not contact the bottom inner side of the insulating housing 2, and an FFC cable is movably inserted within the gap. The width of the FFC cable matches the width of the inner side of the insulating housing 2. This design, where the anti-slip pad 141 does not contact the bottom inner side of the insulating housing 2 and the FFC cable is movably inserted within the gap, ensures that the FFC cable is effectively clamped and positioned within the connector. Simultaneously, the material and structural design of the anti-slip pad 141 also increases the friction between it and the FFC cable, thereby preventing the FFC cable from loosening or falling off during use. In addition, the design of the FFC cable width matching the width of the inner side of the insulating housing 2 also ensures the stability and reliability of the connection.

[0038] When using this invention, ensure the FPC cable is ready and its width matches the inner width of the insulating housing 2. Check the integrity of the insulating housing 2 and the insulating cover 1, ensuring there are no damaged or missing parts. Insert the FPC cable into the inner side of the insulating housing 2, ensuring the gold fingers of the cable are correctly aligned with the connecting terminal 21. Ensure the wire sheath of the FPC cable does not interfere with the normal operation of the connecting terminal 21 and the grounding plate 22. Rotate the insulating cover 1 90 degrees along the top of one side of the grounding plate 22 so that it covers the insulating housing 2. Ensure the first mounting hole 13 on the insulating cover 1 aligns with the second mounting hole 13 on the insulating housing 2. Align the holes 25, pass the two captive screws 132 through the first nut post 131 and screw them into the second nut post 251 until they are firmly tightened. This process ensures that the insulating cover 1 is firmly fixed to the insulating housing 2 and that the additional pressure provided by the captive screws 132 effectively clamps and positions the FFC cable. After clamping and positioning, check that the insulating cover 1 is completely closed and there is no looseness or gap. Gently shake the FFC cable to ensure that it is firmly clamped in the connector and there are no signs of loosening or falling off. Perform the necessary electrical tests to ensure the performance and reliability of the connector.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
