Description

Technical Field

[0001] The present invention relates to the technical field of FPCs, and in particular to an FPC connector capable of double-sided connection of flat cables. Background Art

[0002] FPC is generally long and thin, with pluggable pins at both ends, which can be directly connected to the connector or welded to the product. The middle is usually a circuit.

[0003] The FPC connector is a bridge of communication between blocked or isolated circuits within the circuit, which is connected to the FPC to enable the current to flow and the circuit to achieve the intended function. It is also a bridge for signal transmission and reception.

[0004] However, the existing FPC connector has the following disadvantages when setting up signal transmission:

[0005] First, the FPC connector that can connect the cable on both sides is not stable enough when connecting the FPC, which causes the entire contact part to shake, thereby affecting the signal transmission. Secondly, the installation of the FPC is not convenient enough. Since the double-sided plug-in connection is prone to deviation, multiple debugging is required.

[0006] In view of the above shortcomings, most FPC connectors are of combined installation structure, which leads to poor moisture-proof stability of the installed FPC connector. During long-term use, the internal FPC gold fingers and contact terminals will be affected, resulting in failures. Therefore, we propose an FPC connector that can connect cables on both sides. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings existing in the prior art. First, the FPC connector that can connect cables on both sides is not stable enough in connection with the contact terminals when the FPC is plugged in and connected, resulting in shaking of the entire contact part, thereby affecting signal transmission. Secondly, the installation of the FPC is not convenient enough. Since the double-sided plug-in connection is prone to deviation, multiple debugging is required. In view of the above shortcomings, most FPC connectors are combined installation structures, which leads to poor waterproof and moisture-proof performance of the installed FPC connector, which will affect the internal FPC gold fingers and contact terminals during long-term use.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An FPC connector capable of double-sided cable connection includes a first connection seat and a second connection seat, the second connection seat being arranged on the right side of the first connection seat, a wiring fixing mechanism being provided on the outside of each of the first and second connection seats, a third connection seat being arranged on the right side of the first connection seat, a plug seat being arranged on the right side of the third connection seat, a double-sided contact mechanism being provided inside the plug seat, and a waterproof mounting seat being provided on the periphery of the third connection seat;

[0011] The wiring fixing mechanism includes a wiring seat, a wiring port is provided on the outside of the wiring seat, rubber pads are provided on the upper and lower sides of the wiring port, a receiving circular groove is provided on the top of the wiring seat, a threaded hole is provided inside the receiving circular groove, a threaded knob is provided inside the threaded hole, and a fixing piece is provided at the bottom of the threaded knob and above the rubber pad;

[0012] The double-sided contact mechanism includes a contact box, a terminal plate is arranged at the inner center of the contact box, limit plates are arranged on the upper and lower sides of the terminal plate, limit pads are arranged on the inner sides of the two limit plates, and several pressure springs are arranged between the two limit plates and the contact box.

[0013] As a preferred solution of the present invention, the waterproof mounting seat includes an upper mounting seat and a lower mounting seat, the lower mounting seat is arranged at the bottom of the upper mounting seat, the inner side walls of the upper mounting seat and the lower mounting seat are both provided with waterproof tight pads, and the top of the upper mounting seat is provided with a connecting block near the corner.

[0014] As a preferred solution of the present invention, the upper mounting seat and the lower mounting seat are fixed by bolts, the waterproof tight gasket is made of rubber material, and the connecting block corresponds to the mounting hole.

[0015] The technical effect of adopting the above-mentioned further scheme is: after the overall installation is completed, the upper mounting seat and the lower mounting seat are correspondingly mounted on the third connecting seat, and then the upper mounting seat and the lower mounting seat are fixed by bolts, and at the same time, the connecting block mounting holes are made corresponding, so that the first connecting seat and the second connecting seat are fixed by bolts.

[0016] As a preferred solution of the present invention, the plug-in protrusion is a strong magnet, the plug-in protrusion is matched with the plug-in groove, and the adsorption surface is made of iron.

[0017] The technical effect of adopting the above further solution is: the plug-in protrusion with the properties of a strong magnet is docked with the plug-in groove and adsorbed with the adsorption surface of the iron material, thereby making the connection between the waterproof mounting seat, the first connecting seat and the second connecting seat more stable.

[0018] As a preferred solution of the present invention, the socket is matched with the socket slot, and the waterproof fixing pad is made of rubber.

[0019] The technical effect of adopting the above further solution is: by docking the socket with the socket slot, the first connection socket and the second connection socket are plugged together, and the waterproof fixing pad makes the plugging more tight and stable, and effectively waterproof.

[0020] As a preferred solution of the present invention, the two wiring seats are integrally formed with the first connecting seat and the second connecting seat.

[0021] As a preferred solution of the present invention, the two rubber pads fit together, the receiving circular groove is adapted to the threaded knob, and the threaded knob is threadedly connected to the threaded hole.

[0022] The technical effect of adopting the above-mentioned further solution is: the upper and lower sets of rubber pads fit together to protect the FPC circuit plugged into the contact box and prevent it from shaking, and turning the threaded knob causes the bottom threaded rod to descend in the threaded hole, so that the fixing plate applies pressure to the rubber pad, further limiting the FPC circuit, ensuring its plug-in stability, and not damaging the FPC circuit.

[0023] As a preferred solution of the present invention, the two wiring ports are designed to be staggered up and down.

[0024] The technical effect of adopting the above further solution is: by designing the wiring ports in an upper and lower staggered manner, the FPC circuits at both ends will not occupy the contact terminals on the same side, avoiding multiple debugging during installation.

[0025] As a preferred solution of the present invention, the contact box is bonded to the socket.

[0026] As a preferred solution of the present invention, the terminal board is a double-sided structure, and the limiting pad is made of silicone material.

[0027] The technical effect of adopting the above further solution is that the limiting pad made of silicone material protects the gold finger of the FPC, making the gold finger and the contact terminal closer.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention, through the design of the wiring fixing mechanism and the double-sided contact mechanism, firstly addresses the problem that the connection of the contact terminal is not stable enough, resulting in the shaking of the entire contact part. When the FPC is docked to the terminal board, the contraction of the pressure spring and the filling of the silicone pad make the contact between the FPC and the terminal board more stable. At the same time, the upper and lower sets of rubber pads fit together to protect the FPC circuit plugged into the contact box from shaking. Turning the threaded knob causes the bottom threaded rod to descend in the threaded hole, so that the fixing piece applies pressure to the rubber pad to ensure that the FPC does not shake or fall off, thereby effectively ensuring the connection stability between the FPC and the connector, making the connection more stable. At the same time, the gold fingers in contact with the terminal board and the FPC circuit are protected from damage, thereby making the signal transmission more stable.

[0030] Secondly, the installation of FPC is not convenient enough. Since double-sided plug-in connection is prone to deviation, multiple debugging is required. According to the above connection and fixing method, the parallel wiring interface is staggered up and down to prevent the FPC lines at both ends from occupying the contact terminals on the same side, avoiding multiple debugging during installation. After plugging and docking the FPC lines, you only need to turn the threaded knob to complete the fixation.

[0031] In the present invention, through the design of the first connecting seat, the second connecting seat and the waterproof mounting seat, the connection between the first connecting seat and the second connecting seat is specifically that the plug-in protrusion is docked with the plug-in groove and adsorbed on the adsorption surface, and the plug-in connection between the plug-in seat and the plug-in groove is more tightly and stably filled with the waterproof fixing pad, thereby preventing the entry of moisture and achieving a certain waterproof effect. Finally, the waterproof mounting seat is fixed as a whole, and the internal waterproof tight pad is used to make the waterproof mounting seat and the third connecting seat more tightly fixed, achieving a waterproof effect, preventing moisture from entering during long-term use and affecting the internal FPC gold fingers and contact terminals, thereby ensuring the normal operation of the connector.
