Description

Technical Field

[0001] This utility model belongs to the field of FPC connector technology, and in particular relates to a connector that is convenient for projector-type FPCs. Background Technology

[0002] FPC is a flexible printed circuit board. FPC is a connector assembly for other electronic devices. It connects different boards through a series of contact points and screws to form a complete circuit, realizing information transmission and power supply between boards. Its design is flexible and its performance is stable and reliable. It is an indispensable component of electronic devices and has the characteristics of flexibility, lightness and high precision. It has been widely used in many fields such as projectors.

[0003] When in use, the FPC needs to be inserted into the connector. The existing connection method between the FPC and the connector is mainly a flip cover type. Specifically, the flip cover is opened first, the FPC is inserted into the connector from the top at an angle, and the flip cover is closed tightly. However, when the projector is working, its internal cooling fan will vibrate. Long-term vibration will cause the flip cover to loosen, resulting in the FPC losing connection with the connector, thus preventing the projector from operating normally. Therefore, we propose a connector that is convenient for projector-type FPCs. Utility Model Content

[0004] The purpose of this invention is to provide a connector for projector-type FPCs. Specifically, when one end of the FPC contacts the inclined surface of the locking block, the two locking blocks are pushed away from each other. With continued insertion, a spring pushes the locking blocks into the locking groove, locking the FPC and preventing it from being pulled out. When pulling out, pressing down on the pressing plate causes the extrusion column to move downwards, its bottom contacting and pressing against the inclined surface of the extrusion groove, causing the two locking blocks to move away from each other and leave the locking groove. After unlocking, the FPC can be easily pulled out. This method allows for quick and flexible insertion and removal of the FPC. Simultaneously, this installation method is stable and reliable, ensuring that the FPC and connector maintain stable interconnection even under tensile and vibration environments. This solves the problem that existing connectors struggle to maintain stable interconnection with the FPC under tensile and vibration environments.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a connector for projector-type FPCs, comprising a connector with two solder pads on both the front and back sides, a circuit board mounted on the bottom of the connector, an FPC inserted into the connector, and locking slots on both the front and back sides of the FPC. It also includes:

[0007] A mounting portion, wherein the mounting portion is installed inside the connector, the mounting portion being used to mount the FPC within the connector; and

[0008] A guide portion, which is mounted on the right side of the connector, is used to guide the FPC into the connector;

[0009] The solder feet are used to solder the connector to the circuit board, improve mechanical support, and ensure the stability of the connector on the circuit board.

[0010] Furthermore, the mounting portion includes a pressing component mounted on the top of the connector, the pressing component being used to release the locking of the FPC;

[0011] A locking component, which is installed inside the connector and is used to lock the FPC;

[0012] The locking components are provided in two sets, and after the FPC is locked by the connector, the locking components can be released by pressing the components together.

[0013] Furthermore, the guide portion includes a guide block, which is mounted on the right side of the connector and is used to guide the FPC;

[0014] The guide block has four bevels at its right opening, which guide the FPC into the connector when it comes into contact with any one of the bevels.

[0015] Furthermore, the pressing assembly includes a pressing plate, and a limiting post is fixedly connected to the top of the connector, the limiting post being slidably limited in cooperation with the pressing plate;

[0016] The top of the limiting post is equipped with an anti-detachment ring, which serves as a limiting device.

[0017] Furthermore, a spring is sleeved on the outside of the limiting post, the top end of the spring is fixedly connected to the bottom of the pressing plate, the bottom end of the spring is fixedly connected to the top of the connector, and two extrusion posts are fixedly connected to the bottom of the pressing plate;

[0018] The two extrusion posts are engaged with the connector sliding limit to ensure stability when the pressing plate moves, and the bottom of both extrusion posts is curved.

[0019] Furthermore, the locking assembly includes a locking block, the locking block having an internal compression groove, a second spring fixedly connected to the side of the locking block away from the FPC, and the other end of the second spring fixedly connected to the connector;

[0020] The side of the extrusion groove that contacts the bottom of the extrusion column is set with an inclined surface. When the extrusion column moves downward, the inclined surface can move the locking block.

[0021] Furthermore, the guide portion includes an insert plate, a guide groove one is provided on the top of the FPC, and a guide groove two is provided on the right side of the guide block;

[0022] The FPC has a slot on its left side, and the insert plate is inserted into the slot on the left side of the FPC. The insert plate and the slot work together to prevent misinsertion.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model, by setting up an installation part, specifically, when one end of the FPC contacts the inclined surface of the locking block, pushes the two locking blocks away from each other. After continuous insertion, the second spring pushes the locking block into the locking groove through elastic force, thus locking the FPC and preventing it from being pulled out. When pulling out, press down on the pressing plate, and the extrusion column moves downward. Its bottom contacts and extrudes the inclined surface of the extrusion groove, causing the two locking blocks to move away from each other and leave the locking groove. After the lock is released, the FPC can be pulled out smoothly. This method allows for quick and flexible insertion and removal of the FPC. At the same time, this installation method is stable and reliable, ensuring that the FPC and connector can maintain stable interconnection under tensile and vibration environments.

[0025] 2. This utility model features a guide section. Specifically, after aligning guide groove one and guide groove two on the FPC, a guide block is inserted. The inclined surface of the guide block guides the misaligned FPC into the connector. If the FPC is inserted backwards, the insert plate cannot enter its internal slot. The insert plate can only enter the slot when guide groove one and guide groove two are on the same straight line. This design can prevent misinsertion that could cause the FPC to malfunction. At the same time, since the connector and FPC are relatively small, it is difficult for users to correctly and smoothly insert the FPC into the connector during actual use. Therefore, this installation method can better assist users in insertion and removal.

[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5 As shown, this utility model is a connector for projector-type FPCs, including a connector 1. The connector 1 has two solder pads 11 mounted on both its front and back sides. A circuit board 12 is mounted on the bottom of the connector 1. An FPC 13 is inserted into the connector 1. The FPC 13 has locking grooves 131 on both its front and back sides. It also includes:

[0037] Mounting part 2, mounted inside connector 1, is used to mount FPC 13 inside connector 1; and

[0038] Guide part 3 is installed on the right side of connector 1 and is used to guide FPC 13 into connector 1;

[0039] The solder pad 11 is used to solder the connector 1 to the circuit board 12, improve mechanical support, and ensure the stability of the connector 1 on the circuit board 12.

[0040] Mounting part 2 includes a pressing component 21, which is mounted on the top of connector 1 and is used to release the locking of FPC 13;

[0041] Locking component 22 is installed inside connector 1 and is used to lock FPC 13;

[0042] The locking component 22 is provided in two sets. After the FPC13 is locked by the connector 1, the locking component 21 and the locking component 22 can be used together to release the lock.

[0043] The guide section 3 includes a guide block 31, which is mounted on the right side of the connector 1 and is used to guide the FPC 13.

[0044] The guide block 31 has four bevels at the opening on the right side. When the FPC13 comes into contact with any one of the bevels, it will be guided into the connector 1.

[0045] The pressing assembly 21 includes a pressing plate 211, and a limiting post 212 is fixedly connected to the top of the connector 1. The limiting post 212 is slidably limited to the pressing plate 211.

[0046] Among them, the top of the limiting post 212 is equipped with an anti-detachment ring, which serves as a limiting ring.

[0047] A spring 213 is sleeved on the outside of the limiting post 212. The top end of the spring 213 is fixedly connected to the bottom of the pressing plate 211, and the bottom end of the spring 213 is fixedly connected to the top of the connector 1. Two extrusion posts 214 are fixedly connected to the bottom of the pressing plate 211.

[0048] Among them, the two extrusion posts 214 are slidably limited to the connector 1 to ensure that the pressing plate 211 remains stable when it moves, and the bottom of the two extrusion posts 214 are both curved.

[0049] The locking assembly 22 includes a locking block 221, which has a pressing groove 222 inside. A spring 223 is fixedly connected to the side of the locking block 221 away from the FPC13, and the other end of the spring 223 is fixedly connected to the connector 1. When the left side of the FPC13 contacts the inclined surface of the locking block 221, it pushes the two locking blocks 221 away from each other. After continuous insertion, the spring 223 pushes the locking block 221 into the locking groove 131 through its elastic force, thus locking the FPC13 and preventing it from being pulled out. When pulling out, the pressing plate 211 is pressed down, and the pressing column 214 moves downward. Its bottom contacts and presses the inclined surface of the pressing groove 222, causing the two locking blocks 221 to move away from each other and leave the locking groove 131. After the lock is released, the FPC13 can be pulled out smoothly. This method allows for quick and flexible insertion and removal of the FPC13. At the same time, this installation method is stable and reliable, ensuring that the FPC13 and the connector 1 can maintain stable interconnection under tensile and vibration environments.

[0050] The side of the extrusion groove 222 that contacts the bottom of the extrusion column 214 is set with an inclined surface. When the extrusion column 214 moves downward, the inclined surface can move the locking block 221.

[0051] The guide section 3 includes a plate 32. The top of the FPC13 has a guide groove 33, and the right side of the guide block 31 has a guide groove 34. After aligning the guide groove 33 and the guide groove 34 on the FPC13, the guide block 31 is inserted. The inclined surface of the guide block 31 can guide the misaligned FPC13 into the connector 1. If the FPC13 is inserted in reverse, the plate 32 cannot enter its internal slot. The plate 32 can only enter the slot when the guide groove 33 and the guide groove 34 are on the same straight line. This design can prevent the FPC13 from being mis-inserted and thus unable to be used normally. At the same time, since the connector 1 and the FPC13 are relatively small, it is difficult for users to correctly and smoothly insert the FPC13 into the connector 1 during actual use. Therefore, this installation method can better help users to insert and remove the FPC13.

[0052] The FPC13 has a slot on its left side, and the insert plate 32 is inserted into the slot on the left side of the FPC13. The insert plate 32 and the slot work together to prevent misinsertion.

[0053] One specific application of this embodiment is as follows: In use, the connector 1 is first placed on the circuit board 12, and then several solder feet 11 on both sides of the connector 1 are soldered to the circuit board 12. At this time, the guide slot 1 33 and the guide slot 2 34 on the FPC 13 can be aligned with each other. Then the FPC 13 is inserted into the guide block 31. When the FPC 13 is not aligned with the guide block 31, the inclined surface on the guide block 31 will guide the FPC 13 to help it be better inserted into the connector 1. When the FPC 13 is inserted in reverse, the insert plate 32 cannot enter the slot in the FPC 13. Only when the guide slot 1 33 and the guide slot 2 34 are on the same straight line can the insert plate 32 enter the slot in the FPC 13. This design can prevent the user from accidentally inserting the FPC 13, which would cause the FPC 13 to malfunction.

[0054] When one end of FPC13 contacts the inclined surface of locking block 221, it pushes the two locking blocks 221 to move away from each other. As FPC13 continues to be inserted, spring 223 will push the locking blocks 221 into the locking groove 131 through elastic force, thus locking FPC13. At this time, FPC13 cannot be pulled out. When it is necessary to pull out FPC13, press down on the pressing plate 211 to make the two pressing pillars 214 move downward. When the bottom of the pressing pillars 214 contacts the inclined surface of the pressing groove 222, the pressing pillars 214 will... When the extrusion groove 222 is squeezed, the two locking blocks 221 will move away from each other and leave the locking groove 131. At this time, the FPC13 is unlocked and can be pulled out smoothly. After removing the FPC13, the pressing plate 211 can be released. At this time, the spring 213 will push the pressing plate 211 to reset through its own elastic force. The limiting ring at the top of the limiting post 212 can prevent the pressing plate 211 from disengaging from the limiting post 212. At the same time, when the extrusion post 214 moves up and down, the T-shaped block on it slides with the connector 1, making the movement of the extrusion post 214 more stable and smooth.
