[0071] Reference below Figure 1-Figure 21 The FPC connector 100 according to the embodiment of the present invention is described.

[0072] like Figure 1 As shown, combined Figure 2 and Figure 3 According to an embodiment of the present utility model, the FPC connector 100 includes a base 1, an upper cover 2, a first sealing member 3 and a second sealing member 4.

[0073] Specifically, Figure 1 As shown, combined Figure 2 and Figure 3 The base 1 has a receiving cavity 110, and the upper end of the receiving cavity 110 (such as Figure 1The upper cover 2 is provided at the upper opening of the base 1 and connected to the base 1. An insertion port 5 for inserting the FPC 9 into the accommodating cavity 110 is defined between the base 1 and the upper cover 2. For example, Figure 1 In the example shown, the upper end surface of one of the side walls of the accommodating cavity 110 can be recessed downward to form a recessed portion 151, and the side of the upper cover 2 facing the base 1 can be provided with a protrusion 23 that cooperates with the recessed portion 151. An insertion port 5 can be formed between the recessed portion 151 and the protrusion 23. The insertion port 5 is connected to the accommodating cavity 110. A plurality of strip terminals 8 can be provided in the accommodating cavity 110. The FPC 9 can extend into the accommodating cavity 110 through the insertion port 5 and realize connection with the terminals 8 in the accommodating cavity 110.

[0074] Preferably, the upper cover 2 and the base 1 can be detachably connected, which is simple to assemble and easy to disassemble for later maintenance, and is also convenient for inserting the FPC 9 into the FPC connector 100 or pulling it out from the FPC connector 100. Figure 1 and Figure 2 In the example shown, the upper cover 2 and the base 1 can be connected by snapping, buckles 22 can be provided on the two opposite side walls of the upper cover 2, and a snap hole 14 corresponding to the buckle 22 of the upper cover 2 can be provided on the base 1. The connection between the upper cover 2 and the base 1 is completed by snapping the buckle 22 into the snap hole 14.

[0075] Further, the first seal 3 is formed on the side of the base 1 facing the insertion port 5, and the second seal 4 is formed on the side of the upper cover 2 facing the insertion port 5. When the FPC 9 is inserted into the accommodating cavity 110, the first seal 3 and the second seal 4 form a seal for the insertion port 5. The first seal 3 and the second seal 4 can be silicone seals with good elasticity and deformation ability. The first seal 3 and the second seal 4 can be located at the insertion port 5, and the FPC 9 is suitable for being clamped between the first seal 3 and the second seal 4. After the FPC9 is inserted into the accommodating cavity 110 through the insertion port 5, the upper cover 2 and the base 1 are pressed and fixed. At this time, the FPC9 is clamped in the middle by the first seal 3 and the second seal 4 at the insertion port 5, and the first seal 3 and the second seal 4 are compressed at the same time, so that a stable sealing effect can be achieved between the FPC9 and the base 1, between the FPC9 and the upper cover 2, and at both ends of the FPC9 in the width direction. The sealing of the insertion port 5 of the FPC connector 100 can be achieved, the sealing and safety of the FPC connector 100 can be guaranteed, and the application scenarios of FPC9 and the FPC connector 100 can be expanded.

[0076] According to the FPC connector 100 of the embodiment of the utility model, the upper cover 2 is arranged at the upper end opening of the accommodating cavity 110 of the base 1 and an insertion port 5 is defined between the base 1 and the upper cover 2. At the same time, when the FPC 9 is inserted into the accommodating cavity 110, the first seal 3 formed on the side of the base 1 facing the insertion port 5 and the second seal 4 formed on the side of the upper cover 2 facing the insertion port 5 form a seal on the insertion port 5. Therefore, when the upper cover 2 is fixedly connected to the base 1, the FPC 9 can be clamped in the middle by the first seal 3 and the second seal 4 at the insertion port 5, thereby realizing the sealing of the insertion port 5 of the FPC connector 100, which can ensure the sealing and safety of the FPC connector 100, and further expand the application scenarios of the FPC 9 and the FPC connector 100.

[0077] In some embodiments of the present invention, Figure 1 , Figure 6 and Figure 8 As shown, the first seal 3 is an annular seal. The first seal 3 is disposed between the upper cover 2 and the base 1 and can be disposed around the accommodating cavity 110. The first seal 3 can be a silicone seal with good elasticity and deformation ability. When the upper cover 2 is connected and fixed to the base 1, the first seal 3 will be squeezed and compressed by the upper cover 2 and the base 1, and the surrounding of the accommodating cavity 110 can be sealed to prevent water from penetrating into the accommodating cavity 110 from the connection between the upper cover 2 and the base 1, and the sealing and safety of the inside of the FPC connector 100 can be enhanced.

[0078] In some embodiments of the present invention, Figure 1 As shown, combined Figure 2 and Figure 3 , the base 1 and the upper cover 2 are connected by snapping, for example, Figure 1 and Figure 2 In the example shown, the base 1 and the upper cover 2 can be connected by a lock 6. The structure is simple and easy to install, and no other locking accessories such as screws are required during assembly, which is convenient for disassembly and later maintenance, and also provides convenience for inserting or removing the FPC 9 from the FPC connector 100.

[0079] In some embodiments of the present invention, Figure 1 As shown, combined Figure 2 and Figure 3 The FPC connector 100 further includes a lock 6, one end of which is rotatably connected to the base 1, and the other end of which is adapted to be snapped onto the side of the upper cover 2 that is away from the base 1. This allows the upper cover 2 and the base 1 to be flexibly connected or separated, thereby improving the flexibility and convenience of the FPC connector 100. For example, the upper cover 2 and the base 1 can be connected or separated on the left and right sides (such as Figure 2A lock buckle 6 is respectively arranged on the two side walls (in the left and right directions shown in the figure), and the rotation axis of the rotation connection between the lock buckle 6 and the base 1 can be arranged at the lower end of the side wall of the base 1. When a force is applied to the end of the lock buckle 6 away from the rotation axis toward the center of the upper cover 2, the lock buckle 6 will rotate along the rotation axis, and finally the end of the lock buckle 6 away from the rotation axis will be clamped on the side of the upper cover 2 away from the base 1, thereby completing the clamping connection between the upper cover 2 and the base 1. When a force is applied to the end of the lock buckle 6 away from the rotation axis away from the center of the upper cover 2, the lock buckle 6 rotates along the rotation axis, so that the end of the lock buckle 6 away from the rotation axis is separated from the upper cover 2, and the connection between the upper cover 2 and the base 1 is released.

[0080] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, the peripheral wall of the base 1 has an installation cavity 12, and two opposite inner walls of the installation cavity 12 are provided with a rotating shaft 121, and the axes of the rotating shaft 121 of the two opposite inner walls are arranged in a collinear manner. Figure 1 , Figure 2 and Fig.13 As shown, the lock buckle 6 includes a connecting portion 61 and a clamping portion 62. One end of the connecting portion 61 is provided with an axial hole 611 that matches the rotating shaft 121. The rotating shaft 121 can be inserted into the axial hole 611, so that the lock buckle 6 can rotate around the axis of the rotating shaft 121. The structure is simple and the rotation connection between the lock buckle 6 and the base 1 can be realized. Among them, there can be multiple installation cavities 12, and the multiple installation cavities 12 can be arranged at intervals along the circumferential direction of the accommodating cavity 110. The lock buckle 6 can be multiple corresponding to the installation cavities 12, which can enhance the connection strength of the upper cover 2 and the base 1, thereby improving the stability of the FPC connector 100.

[0081] Furthermore, if Fig.13 , Fig.19 and Fig. 20 As shown, one end of the clamping portion 62 is connected to the other end of the connecting portion 61, the clamping portion 62 and the connecting portion 61 are at an angle, and the other end of the clamping portion 62 extends in a direction away from the connecting portion 61. The clamping portion 62 is suitable for being located on the side of the upper cover 2 away from the base 1 and abutting against the upper cover 2. When a force toward the center of the upper cover 2 is applied to the clamping portion 62, the connecting portion 61 will rotate along the axis of the rotating shaft 121, and finally the side of the clamping portion 62 close to the shaft hole 611 will abut against the side of the upper cover 2 away from the base 1. The clamping portion 62 at an angle to the connecting portion 61 can apply a downward force to the upper cover 2 to achieve the connection between the upper cover 2 and the base 1. The structure is simple and convenient for achieving the clamping connection and fixation of the upper cover 2 and the base 1. When the upper cover 2 and the base 1 need to be separated, a force away from the center of the upper cover 2 is applied to the clamping portion 62 to separate the clamping portion 62 from the upper cover 2. The disassembly operation is simple and convenient, and it is also convenient to insert or remove the FPC 9 from the FPC connector 100.

[0082] In some embodiments of the present invention, Fig.13 , Fig.19 and Fig. 20 As shown, a first pressing portion 621 is provided on the side of the clamping portion 62 facing the upper cover 2, and the first pressing portion 621 abuts against the side of the upper cover 2 away from the base 1. The tightness between the upper cover 2 and the base 1 clamped together can be enhanced, thereby enhancing the sealing and stability of the FPC connector 100. Among them, the first pressing portion 621 can be provided at one end of the clamping portion 62 away from the connecting portion 61 and can be formed as an arc-shaped protrusion protruding toward the upper cover 2. When a force toward the center of the upper cover 2 is applied to the clamping portion 62, the first pressing portion 621 helps to guide the clamping portion 62 to the side of the upper cover 2 away from the base 1, thereby reducing the difficulty of clamping the upper cover 2 and the base 1.

[0083] In some embodiments of the present invention, Figure 1 , Fig.18 and Fig. 20 As shown, a guide groove 21 cooperating with the first pressing portion 621 is provided at a position on the upper surface of the upper cover 2 opposite to the clamping portion 62, the side of the guide groove 21 away from the center of the upper cover 2 is open, and the bottom wall of the guide groove 21 is inclined upward in the direction toward the center of the upper cover 2. Therefore, when a force toward the center of the upper cover 2 is applied to the clamping portion 62, the first pressing portion 621 can slide from the side of the guide groove 21 away from the center of the upper cover 2 along the inclined direction of the bottom wall toward the direction close to the center of the upper cover 2, which is conducive to guiding the clamping portion 62 to the side of the upper cover 2 away from the base 1, reducing the difficulty of clamping the upper cover 2 and the base 1, saving the force applied by the operator, and providing convenience for the operator.

[0084] In some embodiments of the present invention, Figure 1 , Figure 4 and Fig.13 As shown, at least part of the installation cavity 12 passes through the side wall of the accommodating cavity 110, and the installation cavity 12 is open at one end of the side wall of the accommodating cavity 110 close to the upper cover 2. The two opposite sides of the clamping portion 62 are provided with clamping portions 622, and the positions of the clamping portions 622 on the opposite sides of the clamping portion 62 are opposite, and the clamping portions 622 are suitable for abutting against the inner wall of the accommodating cavity 110. When a force toward the center of the upper cover 2 is applied to the clamping portion 62, the connecting portion 61 rotates in the installation cavity 12, driving the clamping portion 62 to abut against the side of the upper cover 2 away from the base 1, and the clamping portion 622 can pass over the two opposite side walls of the installation cavity 12 to reach the accommodating cavity 110 and abut against the inner wall of the accommodating cavity 110, at which time the lock buckle 6 can no longer move in the direction away from the center of the upper cover 2, and the lock buckle 6, the upper cover 2 and the base 1 are clamped and fixed. The stopper portion 622 can play a role of limiting and locking, thereby ensuring the stability of the snap connection between the base 1 and the upper cover 2 , and further ensuring the stability and reliability of the FPC connector 100 .

[0085] It should be noted that the position where the installation cavity 12 communicates with the accommodating cavity 110 is located above the lower surface of the first sealing member 3 , and after the upper cover 2 and the base 1 are connected, the sealing of the FPC connector 100 can be ensured.

[0086] In some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 As shown, avoidance grooves 122 for avoiding the locking portion 622 are provided on the two opposite inner side walls of the installation cavity 12, and the side of the avoidance groove 122 facing away from the accommodating cavity 110 is open, so that the locking portion 622 passes through the side of the avoidance groove 122 facing away from the accommodating cavity 110, which is convenient for guiding the locking portion 622 to cross the two opposite side walls of the installation cavity 12 to reach the accommodating cavity 110, thereby reducing the difficulty of the clamping connection between the lock buckle 6, the upper cover 2 and the base 1, which can save the operator's force and provide convenience for the operator.

[0087] In some embodiments of the present invention, Fig.13 , Fig.19 and Fig. 20 As shown, when the clamping portion 62 abuts against the upper cover 2, the upper surface of the clamping portion 62 has a force-applying surface 623, and the force-applying surface 623 is inclined downward in the direction toward the center of the upper cover 2. When the operator disassembles the clamping connection between the upper cover 2 and the base 1, it is necessary to apply a force away from the center of the upper cover 2 to the clamping portion 62. The operator's hand can be placed on the force-applying surface 623 to pry the clamping portion 62. The inclined force-applying surface 623 on the clamping portion 62 helps to apply force, which can reduce the difficulty of operation and save effort for the operator. Preferably, a plurality of protrusions distributed at intervals can be provided on the force-applying surface 623 to increase friction and further provide convenience for the operator.

[0088] In some embodiments of the present invention, Fig.13 , Fig.18 and Fig. 20 As shown, one end of the lock buckle 6 that is rotatably connected to the base 1 is provided with a stop surface 63. When the lock buckle 6 is engaged with the upper cover 2, the stop surface 63 is located on the side of the lock buckle 6 that faces the accommodating cavity 110 and is inclined toward the accommodating cavity 110 from bottom to top. When the operator needs to separate the clamping connection between the upper cover 2 and the base 1, a force away from the center of the upper cover 2 is applied to the clamping portion 62, and the lock buckle 6 will rotate around the axis of the rotating shaft 121 in a direction away from the center of the upper cover 2. By providing the stop surface 63, the end of the lock buckle 6 that is rotatably connected to the base 1 will not collide or interfere with the base 1, and the structural arrangement is reasonable. Fig.18 In the example shown, when the lock buckle 6 rotates a certain angle, the stop surface 63 will abut against the wall of the base 1, so that the lock buckle 6 will no longer rotate, which is convenient for use during the next snap connection and improves convenience.

[0089] In some embodiments of the present invention, Figure 1 and Figure 8 As shown, combined Fig.18 and Fig. 20 , a mounting hole 13 is provided on the base 1, the mounting hole 13 is provided on the inner bottom wall of the accommodating cavity 110, and the upper end of the mounting hole 13 is connected to the accommodating cavity 110. The FPC connector 100 also includes an elastic member 7, at least part of which is provided in the mounting hole 13, and the elastic member 7 is used to drive the upper cover 2 to move upward. The elastic member 7 can be a spring, which has low cost and good elasticity. The length of the elastic member 7 in a natural state without force is greater than the depth of the mounting hole 13. When the upper cover 2 and the base 1 are connected by a snap connection, the elastic member 7 is compressed in the mounting hole 13 by the pressure of the upper cover 2. When the operator disassembles the snap connection between the upper cover 2 and the base 1, the force is applied to make the snap-on portion 62 detach from the upper cover 2. At this time, the elastic member 7 in the mounting hole 13 can apply an upward force to the upper cover 2, so that the upper cover 2 automatically pops up, and the gap between the upper cover 2 and the base 1 becomes larger, which is convenient for the operator to insert the FPC 9 from the insertion port 5 into the accommodating cavity 110.

[0090] In this application, if Figure 8 In the example shown, when the FPC connector 100 is assembled, the elastic member 7 and the first sealing member 3 need to be installed into the accommodating cavity 110 of the base 1 first, and then the upper cover 2 is connected to the base 1 .

[0091] In this application, if Figure 1 and Figure 8 As shown, there are multiple mounting holes 13, and the elastic members 7 are multiple corresponding to the mounting holes 13. The multiple mounting holes 13 are arranged on the support platform 15 and are located in the annular space of the annular first sealing member 3. The multiple elastic members 7 can apply upward force to the upper cover 2 at different positions of the upper cover 2, so that the force is more balanced, thereby ensuring the upper cover 2 to automatically pop up when the upper cover 2 and the base 1 are separated.

[0092] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, a latch hole 14 is provided on the inner peripheral wall of the accommodating cavity 110, and the latch hole 14 penetrates the peripheral wall of the accommodating cavity 110. A latch 22 is provided on the side wall of the upper cover 2 to cooperate with the latch hole 14. The upper cover 2 can be connected to the base 1 through the cooperation of the latch hole 14 and the latch 22, so that when the lock buckle 6 is disengaged from the upper cover 2, the upper cover 2 will not be completely separated from the base 1. For example, Figure 1 and Figure 2In the example shown, there are multiple clamping holes 14, which can be respectively arranged on the left and right side walls of the accommodating cavity 110, and multiple clamping holes 14 can also be arranged at intervals on each side wall of the accommodating cavity 110. The buckles 22 on the side wall of the upper cover 2 are multiple corresponding to the clamping holes 14, which can enhance the stability of the connection between the upper cover 2 and the base 1. Among them, the length of the clamping hole 14 in the up-down direction is greater than the thickness of the buckle 22 in the up-down direction, and the clamping hole 14 plays a limiting role on the buckle 22. When assembling the upper cover 2 and the base 1, the upper cover 2 is placed at the upper end opening of the base 1 and the upper cover 2 is pressed downward, so that the buckle 22 on the side wall of the upper cover 2 is clamped into the clamping hole 14 of the base 1. Through the cooperation of the clamping hole 14 and the buckle 22, while realizing the connection between the upper cover 2 and the base 1, the upper cover 2 is also allowed to move relative to the base 1 in the up-down direction.

[0093] In this application, if Fig.19 and Fig. 20 As shown, when the lock buckle 6 is engaged with the upper cover 2, under the force of the engaging portion 62, the first seal 3 is squeezed and compressed by the upper cover 2 and the base 1, the elastic member 7 is compressed and located in the mounting hole 13, and the first seal 3 and the second seal 4 are squeezed against each other at the insertion port 5. The upper end surface of the buckle 22 is spaced apart from the top wall of the engaging hole 14, the FPC 9 is adapted to be clamped between the first seal 3 and the second seal 4, the upper cover 2 and the first seal 3 are interference fit, and the FPC 9 is inserted into the accommodating cavity 110 at this time, which can ensure the sealing and safety of the FPC 9 at the insertion port 5 and inside the FPC connector 100.

[0094] In this application, if Fig.17 and Fig.18 As shown, when the lock buckle 6 is disengaged from the upper cover 2, the elastic member 7 can apply an upward force to the upper cover 2, and the elastic member 7 drives the buckle 22 to stop against the top wall of the clamping hole 14, the first seal 3 and the second seal 4 are separated, and the upper cover 2 and the first seal 3 are separated. The elastic member 7 can apply force to make the upper cover 2 automatically pop open, and the cooperation between the buckle 22 and the clamping hole 14 prevents the upper cover 2 from completely disengaging from the base 1, providing convenience for the next clamping of the upper cover 2 and the base 1. At the same time, the first seal 3 and the second seal 4 also create a gap of appropriate size at the insertion port 5, which is convenient for the operator to insert or remove the FPC 9 from the insertion port 5 into the accommodating cavity 110.

[0095] In some embodiments of the present invention, Figure 4 , Figure 5 and Figure 8As shown, the bottom wall of the accommodating cavity 110 has a support platform 15 extending along the circumferential direction of the accommodating cavity 110, which is used to place the first sealing member 3. When the upper cover 2 is snap-connected with the base 1, the first sealing member 3 can be clamped between the upper cover 2 and the support platform 15 and seal the accommodating cavity 110 on all sides, which can enhance the tightness between the upper cover 2 and the base 1 that are snap-connected together, thereby enhancing the sealing of the FPC connector 100.

[0096] In this application, if Figure 1 and Figure 2 As shown, combined Figure 4 and Fig. 9 The upper end surface of one side of the peripheral side of the support platform 15 is concave downward to form a concave portion 151, and the upper cover 2 is provided with a protrusion 23 that cooperates with the concave portion 151 on the side facing the base 1. An insertion port 5 is formed between the concave portion 151 and the protrusion 23, which facilitates the FPC 9 to be inserted from the insertion port 5 and extend parallel to the accommodating cavity 110, providing convenience for the operator's operation. On the other hand, the concave portion 151 and the protrusion 23 can define the length of the insertion port 5 in the left-right direction, so that the length of the insertion port 5 in the left-right direction corresponds to the width of the FPC 9, which is conducive to the positioning of the FPC 9 inserted into the FPC connector 100.

[0097] Furthermore, if Figure 6 , Figure 8 and Fig.12 As shown, the first seal 3 is disposed between the support platform 15 and the upper cover 2, and the first seal 3 has a downwardly concave bending portion 31 at a position corresponding to the concave portion 151, so that the first seal 3 and the support platform 15 can be kept in contact, thereby ensuring the sealing effect of the first seal 3. The second seal 4 is disposed on the protruding portion 23, so that after the FPC 9 is inserted from the insertion port 5 formed between the concave portion 151 and the protruding portion 23, it can be clamped between the first seal 3 and the second seal 4, ensuring the sealing of the FPC 9 at the insertion port 5, thereby ensuring the sealing and safety of the FPC connector 100.

[0098] In some embodiments of the present invention, Fig. 9 , Fig.12 and Fig.21As shown, the protruding portion 23 includes a front stopper 231, a mounting portion 232 and a rear stopper 233. The upper end of the front stopper 231 is connected to the lower surface of the upper cover 2, the mounting portion 232 is connected to one side of the front stopper 231 along the axial direction of the insertion port 5, the mounting portion 232 is spaced apart from the lower surface of the upper cover 2, and the lower surface of the mounting portion 232 is retracted into the lower surface of the front stopper 231. The rear stopper 233 is connected to one end of the mounting portion 232 that is away from the front stopper 231, the rear stopper 233 is spaced apart from the lower surface of the upper cover 2, the upper surface and the lower surface of the mounting portion 232 are retracted into the upper surface and the lower surface of the rear stopper 233 respectively, and the second sealing member 4 is sleeved on the mounting portion 232. The second seal 4 is provided with a sealing cavity 43, which penetrates the second seal 4 in the thickness direction. The protrusion 23 structure mentioned above facilitates the sealing cavity 43 of the second seal 4 to pass through the rear stopper 233 and then be sleeved on the mounting portion 232. The structure is simple and convenient for assembly. The lower surface of the mounting portion 232 is retracted into the lower surface of the front stopper 231 and the rear stopper 233, and the upper surface of the mounting portion 232 is retracted into the upper surface of the front stopper 231 and the rear stopper 233, which has a limiting effect and is conducive to the fixing of the second seal 4.

[0099] In some embodiments of the present invention, Fig.10 and Fig.11 As shown, the inner peripheral wall of the second seal 4 is provided with an inner ring sealing lip 41 extending along the circumferential direction of the second seal 4, which can increase the friction between the second seal 4 and the mounting portion 232, thereby enhancing the stability of the connection between the second seal 4 and the protrusion 23. The outer peripheral wall of the second seal 4 is provided with an outer ring sealing lip 42 extending along the circumferential direction of the second seal 4. When the upper cover 2 is connected to the base 1 by snapping, the first seal 3 and the second seal 4 are squeezed against each other, and the outer ring sealing lip 42 is compressed and deformed by force, which can enhance the sealing effect between the first seal 3 and the second seal 4.

[0100] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, a groove 152 is provided on the upper surface of the support platform 15, and the groove 152 extends along the length direction of the support platform 15. Part of the first seal 3 is provided in the groove 152, which can limit and position the first seal 3. Among them, the width of the groove 152 matches the first seal 3 and the depth of the groove 152 is less than the thickness of the first seal 3, so that the groove 152 can limit and position the first seal 3 without affecting the sealing effect of the first seal 3.

[0101] Furthermore, at least one of the two side walls in the width direction of the groove 152 is provided with a plurality of retaining portions 153 spaced apart along the length direction of the groove 152, the retaining portions 153 cooperate with the side walls of the first seal 3 facing away from the accommodating cavity, and the retaining portions 153 can be formed as special-shaped protrusions, which can enhance the friction between the first seal 3 and the groove 152, increase the compression of the first seal 3 in the width direction of the groove, and further enhance the tightness and limiting effect between the first seal 3 and the groove 152.

[0102] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, a sealing lip 32 is provided on at least one of the upper and lower surfaces of the first seal 3. The sealing lip 32 extends along the length direction of the first seal 3. When the first seal 3 is an annular seal, the sealing lip 32 extends in an annular shape along the circumferential direction of the first seal 3. When the upper cover 2 is connected with the base 1 by snapping, the first seal 3 is squeezed by the upper cover 2 and the base 1, and the sealing lips 32 on the upper and lower surfaces of the first seal 3 are compressed and deformed by force, which can enhance the sealing effect between the first seal 3 and the upper cover 2 and between the first seal 3 and the base 1. In addition, on the same surface of the first seal 3, there are multiple sealing lips 32 spaced apart along the width direction of the first seal 3, and multiple sealing lips 32 can further enhance the sealing effect between the first seal 3 and the upper cover 2 and between the first seal 3 and the base 1.

[0103] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the two inner walls of the accommodating cavity 110 located on opposite sides of the insertion port 5 are provided with guide surfaces 111, and along the insertion direction of the FPC 9, the two guide surfaces 111 are inclined toward each other. When the operator inserts the FPC 9 from the insertion port 5 into the FPC connector 100, if the position of the FPC 9 deviates in the left-right direction, the guide surfaces 111 can play a guiding role, so that the FPC 9 slides into the accommodating cavity 110 along the inclined direction of the guide surface, ensuring that the FPC 9 is in the correct position in the FPC connector 100, without the operator's alignment, reducing the difficulty of inserting the FPC 9 and improving the convenience of operation.

After the operator inserts the FPC9 into the accommodating cavity 110, the base 1 and the upper cover 2 are locked by the lock buckle 6. At this time, the locking column 25 on the lower surface of the upper cover 2 can be inserted into the locking hole 91 of the FPC9, and the lower surface of the locking boss 24 is against the upper surface of the FPC9. In this way, the FPC9 can be locked in the FPC connector 100, which can prevent the FPC9 from falling off from the FPC connector 100, and enhance the connection stability between the FPC9 and the FPC connector 100.

[0105] Furthermore, if Fig. 9 and Fig. 20 As shown, a second pressing portion 26 is provided on the lower surface of the upper cover 2, and the second pressing portion 26 is adapted to abut against the upper surface of the FPC 9. When the base 1 and the upper cover 2 are locked by the lock 6, the second pressing portion 26 can abut against the upper surface of the FPC 9, so that the FPC 9 is clamped between the second pressing portion 26 and the bottom wall of the accommodating cavity 110, which can enhance the holding force of the FPC 9 in the FPC connector 100 and improve the stability of the FPC 9.

[0106] In some embodiments of the present invention, Figure 4 , Fig.15 and Fig.21 As shown, a plurality of spaced-apart terminal grooves 16 are provided on the bottom wall of the accommodating cavity 110, and the FPC connector 100 also includes a terminal 8, wherein there are a plurality of terminals 8, and one end of each of the plurality of terminals 8 is respectively located in the terminal groove 16 and is suitable for connecting with the FPC 9, and the thickness of at least a portion of the terminal 8 located in the terminal groove 16 is greater than the depth of the terminal groove 16.

[0109] Furthermore, if Figure 8 , Fig.14 and Fig.21 As shown, a contact portion 811 connected to the FPC 9 is provided above the head 81. The contact portion 811 may be an arc-shaped protrusion and the contact portion 811 protrudes from the terminal slot 16, so as to facilitate the contact and connection between the terminal 8 and the FPC 9, and enhance the stability of the conduction between the FPC 9 and the terminal 8. In addition, the tail portion 83 extends downwardly at an angle, so as to facilitate the connection between the tail portion 83 and the circuit board 10. The end of the tail portion 83 away from the middle portion 82 is provided with a welding portion 831 connected to the circuit board 10. The welding portion 831 can be welded and connected to the circuit board 10 by a soldering process, thereby completing the conduction between the FPC connector 100 and the circuit board 10.
