[0002] FPC (Flexible Printed Circuit) connectors are electrical connectors specifically designed for flexible printed circuit boards (FPCs). Compared to traditional connectors, FPC connectors are smaller and lighter, adapting to the needs of high-density and miniaturized designs. Their flexible structure enables three-dimensional wiring, effectively saving installation space and reducing assembly difficulty. They also possess excellent shock resistance and stable electrical performance, making them particularly suitable for applications involving frequent bending and space constraints, thus improving the overall reliability and integration of electronic products. With the rapid development of the new energy industry and the continuous advancement of intelligent upgrades in automobiles, FPC connectors play a crucial role in enabling signal or energy transmission.

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The inventors discovered through analysis of existing technologies that the reason for the high cost of existing dual-row FPC connector structures is that, in order to achieve the installation of dual-row FPCs, the male end structure of existing dual-row FPCs usually requires the FPC to be fixed by a sliding latch or a flip-type actuator, which increases the design and manufacturing costs.

[0021] Reference Figure 1-7 This illustration shows a dual-row FPC connection male terminal provided in an embodiment of this application, including a first housing 1, a first FPC board 2, and a second FPC board 3; The first housing 1 has a first insertion slot 11 and a second insertion slot 12; the first insertion slot 11 and the second insertion slot 12 are arranged opposite to each other; The first FPC board 2 is fixed inside the first insertion slot 11; the second FPC board 3 is fixed inside the second insertion slot 12. The first insertion slot 11 is provided with a plurality of first connecting slots 111 corresponding to the contacts of the first FPC board 2; the second insertion slot 12 is provided with a plurality of second connecting slots 121 corresponding to the contacts of the second FPC board 3. When the male terminal is connected to the corresponding female terminal, the first elastic terminal 61 of the female terminal is electrically connected to the first FPC board 2 through the first connecting groove 111, and the second elastic terminal 62 of the female terminal is electrically connected to the second FPC board 3 through the second connecting groove 121.

[0022] In the embodiments of this application, addressing the issue that existing dual-row FPC connector structures rely on sliding latches or flip-top actuators to fix the FPC, resulting in high costs, this application provides a solution that directly fixes the dual-row FPC to the male end housing's insertion slots and provides connecting slots at the contacts of the FPC board for preventing creepage. Specifically, a dual-row FPC connection male end includes a first housing 1, a first FPC board 2, and a second FPC board 3; the first housing 1 has a first insertion slot 11 and a second insertion slot 12; the first insertion slot 11 and the second insertion slot 12 are arranged opposite to each other; the first FPC board 2 is fixed... The first insertion slot 11 is located inside the second FPC board 3, which is fixed inside the second insertion slot 12. The first insertion slot 11 has several first connecting slots 111 corresponding to the contacts of the first FPC board 2. The second insertion slot 12 has several second connecting slots 121 corresponding to the contacts of the second FPC board 3. When the male end is connected to the corresponding female end, the first elastic terminal 61 of the female end is electrically connected to the first FPC board 2 through the first connecting slot 111, and the second elastic terminal 62 of the female end is electrically connected to the second FPC board 3 through the second connecting slot 121. This application realizes the installation of double-row FPCs through the first insertion slot 11 and the second insertion slot 12, reducing costs, and realizes anti-creep protection of the FPC board and elastic contact with the female end terminals through the connecting slots.

[0023] The following will further describe a dual-row FPC connection male terminal in this exemplary embodiment.

[0024] It should be noted that, as independent insertion slots, the first insertion slot 11 and the second insertion slot 12 can be disposed opposite to each other on the same side of the first housing 1, so that the first FPC board 2 and the second FPC board 3 can be inserted into the first housing 1 side by side. Reference Figure 3 To ensure stable contact, the first insertion slot 11 and the second insertion slot 12 need to provide sufficient preload to the FPC board. The first insertion slot 11 and the second insertion slot 12 may be provided with clamping structures parallel to the corresponding FPC board, as well as slope structures for guiding during insertion. The clamping structures can increase the static friction of the FPC board in the insertion slot to prevent the FPC board from detaching from the insertion slot.

[0025] Reference Figure 2 In one embodiment of this application, the first housing 1 is provided with a first isolation plate 13; The first insertion slot 11 and the second insertion slot 12 are respectively disposed on different sides of the first isolation plate 13.

[0026] It should be noted that the first isolation plate 13 can separate the first FPC board 2 and the second FPC board 3, and can also serve as the plug-in structure of the male end.

[0027] Reference Figure 1 In one embodiment of this application, the first housing 1 has a first guiding cavity 14 and a second guiding cavity 15; the first guiding cavity 14 is connected to the first insertion slot 11; and the second guiding cavity 15 is connected to the second insertion slot 12.

[0028] It should be noted that, as independent guiding cavities, the first guiding cavity 14 and the second guiding cavity 15 can be disposed opposite each other on the same side of the first housing 1, and the guiding cavity and the above-mentioned insertion groove are respectively disposed on different sides of the first housing 1. The first isolation plate 13 is disposed between the first conductive cavity 14 and the second conductive cavity 15; the interior of the first conductive cavity 14 and the interior of the second conductive cavity 15 may be provided with a second isolation plate 16 to form a non-centrally symmetrical anti-misinsertion structure.

[0029] In one embodiment of this application, the first guiding cavity 14 is disposed on the side of the first insertion slot 11 away from the first isolation plate 13; the second guiding cavity 15 is disposed on the side of the second insertion slot 12 away from the first isolation plate 13. The first insertion slot 11 is provided with a plurality of first connecting slots 111 that correspond to the contacts of the first FPC board 2 and communicate with the first conductive cavity 14; The second insertion slot 12 is provided with a plurality of second connecting slots 121 that correspond to the contacts of the second FPC board 3 and communicate with the second conductive cavity 15.

[0030] It should be noted that the first connecting groove 111 and the second connecting groove 121 can be used to guide the elastic terminal of the female end during insertion to ensure reliable contact between the FPC board contacts and the elastic terminal.

[0031] The first connecting groove 111 and the second connecting groove 121 can extend from the end of the FPC board to the inner wall of the first housing 1, increasing the structural strength and heat dissipation area of ​​the first housing 1 and preventing foreign objects from entering.

[0032] Reference Figure 4 In one embodiment of this application, a first locking member 41 and a second locking member 42 are also included; The first locking member 41 and the second locking member 42 are respectively disposed on different sides of the first housing 1; The first locking member 41 is sequentially inserted through the first housing 1 and the first FPC plate 2, and is snapped into the side of the first housing 1; The second locking member 42 is sequentially inserted through the first housing 1 and the second FPC plate 3, and is snapped into the side of the first housing 1.

[0033] It should be noted that the first locking member 41 and the second locking member 42 are equivalent to the connector's TPA (Terminal Position Assurance). Both the first locking member 41 and the second locking member 42 can be engaged from both sides of the first housing 1, enhancing the stability of the engagement. The first locking member 41 and the second locking member 42 are detachably mounted on the first housing 1, eliminating the need for a sliding latch or flip-top actuator to secure the FPC board to the first housing 1.

[0034] Reference Figure 2 and Figure 4 In one specific implementation, the side of the first housing 1 may be provided with a pre-installation slot 181 and an installation slot 182. Before installing the FPC board, the first locking member 41 and the second locking member 42 can be engaged with the pre-installation slot 181. After the FPC board is installed, the first locking member 41 and the second locking member 42 can be pressed to engage with the installation slot 182, thereby completing the secondary locking.

[0035] Reference Figure 5 and Figure 7 In one embodiment of this application, first positioning holes 21 are respectively provided on both sides of the first FPC board 2; The second FPC board 3 has second positioning holes 31 on both sides; The first locking member 41 passes through the first positioning hole 21; the second locking member 42 passes through the second positioning hole 31.

[0036] It should be noted that the positioning holes on both sides of the FPC board can ensure that the FPC board can be more stably fixed in the corresponding insertion slots.

[0037] Reference Figure 6 In one embodiment of this application, a third positioning hole 131 corresponding to the first positioning hole 21 and the second positioning hole 31 is provided between the first insertion slot 11 and the second insertion slot 12; the first locking member 41 and the second locking member 42 pass through the third positioning hole 131.

[0038] It should be noted that the third positioning hole 131 can be provided on the first isolation plate 13; the first positioning hole 21, the second positioning hole 31 and the third positioning hole 131 are provided in a corresponding manner, so that the FPC board can be fixed through the structure of the first isolation plate 13.

[0039] Reference Figure 5 In one embodiment of this application, a first positioning part 22 and a second positioning part 23 are respectively provided on both sides of the first FPC board 2; wherein, the first positioning part 22 and the second positioning part 23 are asymmetrical structures; The first housing 1 is provided with a first limiting part 112 corresponding to the first positioning part 22, and a second limiting part 113 corresponding to the second positioning part 23; The first positioning part 22 abuts against the first limiting part 112, and the second positioning part 23 abuts against the second limiting part 113.

[0040] It should be noted that the first limiting part 112 and the second limiting part 113 can be disposed in the first insertion slot 11; the first positioning part 22 and the second positioning part 23 realize the foolproof insertion of the first FPC board 2.

[0041] Reference Figure 7 In one embodiment of this application, a third positioning part 32 and a fourth positioning part 33 are respectively provided on both sides of the second FPC board 3; wherein, the third positioning part 32 and the fourth positioning part 33 are asymmetrical structures; The first housing 1 is provided with a third limiting part 122 corresponding to the third positioning part 32, and a fourth limiting part 123 corresponding to the fourth positioning part 33; The third positioning part 32 abuts against the third limiting part 122, and the fourth positioning part 33 abuts against the fourth limiting part 123.

[0042] It should be noted that the third limiting part 122 and the fourth limiting part 123 can be disposed in the second insertion slot 12; the third positioning part 32 and the fourth positioning part 33 realize the foolproof insertion of the second FPC board 3.

[0043] Reference Figure 1-2 , Figure 5 and Figure 7 In a specific embodiment of this application, the first housing 1 is provided with a second isolation plate 16; The second isolation plate 16 passes through the first insertion slot 11 and the second insertion slot 12; The first FPC board 2 has a first positioning groove 24 at its end corresponding to the second isolation plate 16; the second FPC board 3 has a second positioning groove 34 at its end corresponding to the second isolation plate 16. The first positioning groove 24 and the second positioning groove 34 are engaged with both sides of the second isolation plate 16.

[0044] It should be noted that the contacts of the FPC board are equivalent to the gold finger structure, which does not require additional connecting wires or adapters and can be directly connected through the edge of the FPC board, reducing space occupation. The first positioning groove 24 and the second positioning groove 34 make the conductive contacts of the gold fingers asymmetrically distributed, avoiding reverse insertion of the FPC board. Since the first guide cavity 14 is connected to the first insertion slot 11, and the second guide cavity 15 is connected to the second insertion slot 12, the second isolation plate 16 can also form an anti-misinsertion structure between the first guide cavity 14 and the second guide cavity 15.

[0045] Reference Figure 4 and Figure 8-10 This application provides a dual-row FPC connector, including a male terminal as described in any embodiment of this application, and a female terminal corresponding to the male terminal.

[0046] It should be noted that the female terminal is used for electrical connection with the FPC board in the male terminal.

[0047] In one embodiment of this application, the female end is provided with a first elastic terminal 61 corresponding to the contact of the first FPC board 2, and a second elastic terminal 62 corresponding to the contact of the second FPC board 3. When the male terminal is connected to the female terminal, the first elastic terminal 61 is electrically connected to the first FPC board 2 through the first connecting groove 111 of the first plug slot 11, and the second elastic terminal 62 is electrically connected to the second FPC board 3 through the second connecting groove 121 of the second plug slot 12.

[0048] It should be noted that the flexible terminals correspond to the connecting slots, ensuring that the terminals and FPC board contacts are connected in a one-to-one manner to prevent misconnection or short circuit between adjacent contacts or terminals.

[0049] Reference Figure 9-10 In a specific embodiment of this application, the female end includes a second housing 5; the second housing 5 is provided with a third guiding cavity 51 corresponding to the first isolation plate 13; The first elastic terminal 61 and the second elastic terminal 62 are respectively disposed on different sides of the third conductive cavity 51, and the third conductive cavity 51 is provided with a deformation accommodating cavity 511 corresponding to the first elastic terminal 61 and the second elastic terminal 62.

[0050] It should be noted that when the male end and the female end are connected, due to the compression of the FPC board, the first elastic terminal 61 and the second elastic terminal 62 undergo elastic deformation and move within the corresponding deformation accommodating cavity 511. The contacts of the FPC board maintain elastic contact with the plug portion of the corresponding elastic terminal elastic protrusion structure, thereby ensuring reliable contact and helping to eliminate poor contact caused by assembly position errors, vibration displacement, etc., thus ensuring the electrical connection performance of the assembled dual-row FPC connectors. Meanwhile, because the contacts of the FPC board and the corresponding elastic terminals are in sliding contact, the contact area is small, and the elastic terminals also have a yielding effect on the FPC unit, resulting in less insertion resistance between the male and female terminals, making the insertion operation more convenient and effortless. Since the spring terminals and FPC contacts are elastically matched one-to-one through connecting slots, this enhances the toughness and impact resistance of the connection, significantly improving the reliability of the connection.

[0051] Reference Figure 9 In one specific embodiment of this application, the second housing 5 is provided with a fourth guiding cavity 52 corresponding to the second isolation plate 16; When the male end is connected to the female end, the first isolation plate 13 is disposed inside the third guide cavity 51, and the second isolation plate 16 is disposed inside the fourth guide cavity 52.

[0052] It should be noted that when the male end is inserted in reverse, the second isolation plate 16 and the fourth conductive cavity 52 are not in corresponding positions, which causes the first housing 1 to be unable to be inserted into the second housing 5, thus achieving plug-in error prevention.

[0053] Reference Figure 4 and Figure 8 In one specific embodiment of this application, positioning pieces 53 are respectively provided on both sides of the second housing 5.

[0054] It should be noted that the female end can be mounted on the circuit board of the electrical equipment via the positioning piece 53.

[0055] Reference Figure 1 and Figure 9 In a specific embodiment of this application, the first housing 1 is provided with buckle members 17 on both sides, the second housing 5 is provided with buckle members 54 corresponding to the buckle members 17 on both sides, and buckle guide grooves 55 for accommodating the buckle members 17.

[0056] As can be seen from the above embodiments of this application, by setting multiple foolproof structures in the connector, the installation difficulty and usage difficulty of the connector can be reduced to the greatest extent, thereby reducing human error of the connector and ensuring normal use of the connector.

[0057] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
