Description
Technical Field
[0001] This utility model relates to the field of FPC connector technology, and specifically to a connection structure for connecting FPC connectors. Background Technology
[0002] The electrical connection between existing aluminum-based FPCs / FFCs and external systems typically uses aluminum wire bonding technology to connect the pins to the external electrical system. Alternatively, connectors for flat flexible cables can be installed on the FPC / FFC to achieve the connection with the external electrical system.
[0003] A search revealed a utility model patent with publication number CN 220544274U, which discloses a connection structure for connecting an FPC or FFC to a connector. This falls under the technical field of connecting FPC / FFC to electrical systems. The patent includes an FPC or FFC and a connector, connected via a connector body. The connector body includes a PCB adapter board with the FPC or FFC and the connector on both sides; and a connecting wire with its two ends fixed to the FPC or FFC and the connector, respectively. This provides a highly versatile connection structure, allowing interconnection with any external electrical system using different connector models.
[0004] Although the aforementioned patent allows for interconnection with any external electrical system using different types of connectors through this connection structure, poor contact can easily occur when the connectors are in contact with the pins on the FPC flexible board, thus affecting the stability of the connection between the connectors and the FPC flexible board.
[0005] Therefore, it is necessary to propose a connection structure for FPC connector connection to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a connection structure for FPC connector connection. Through the mutual cooperation between the internal parts of the docking mechanism, the connection and fixation between the connection end and the FPC flexible board can be completed. It also facilitates the compression of the contact between the female pin and the female pin, making the contact between the female pin and the female pin more reliable. This solves the problem in the prior art where poor contact easily occurs when the connector is connected to the pins on the FPC flexible board, thus affecting the connection stability between the connector and the FPC flexible board.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a connection structure for connecting FPC connectors, including a connection end, an FPC flexible plate connected to the right side of the connection end, a docking mechanism connected between the connection end and the FPC flexible plate and extending into the interior of the connection end, and a protective mechanism slidably connected to the outer wall of the connection end and extending into the interior of the FPC flexible plate.
[0008] The docking mechanism includes multiple sub-pins, which are mechanically fixed to the outer wall of the FPC flexible board near the connecting end and extend into the interior of the connecting end. Multiple female pins are mechanically fixed inside the connecting end and located above the sub-pins. Multiple docking posts are mechanically fixed to the top left side of the FPC flexible board and extend into the interior of the connecting end. Multiple support plates are slidably connected inside the connecting end and located at the bottom of one side of the docking posts. A pressing post is mechanically fixed to the bottom of the support plate and fits against the top of the female pin. A telescopic spring is mechanically connected between the bottom of the support plate and the interior of the connecting end.
[0009] The protective mechanism includes a support column, which is slidably connected to both ends of the top of the connecting end. A protective cover plate is slidably connected to the top of the support column, and a locking plate is mechanically fixed to the bottom of the protective cover plate, which extends through the connecting end into the interior of the FPC flexible board.
[0010] Preferably, the protective mechanism further includes a limiting slider, which is mechanically fixed to both ends of the outer wall of the protective cover and slidably connected to the inner wall of the support column. A limiting spring is mechanically fixed between the bottom end of the limiting slider and the support column.
[0011] Preferably, the connector has an internal socket that matches the sub-pin and mating post. The sub-pin and the female pin are curved in shape, and the female pin has a certain degree of elasticity.
[0012] Preferably, the surface of the support plate and the contact surface of the docking post are both set as arc surfaces, the inside of the connecting end is provided with a telescopic groove that matches the pressing post, and the contact surface between the bottom end of the pressing post and the top end of the female pin is an arc surface.
[0013] Preferably, the top of the connecting end is provided with a sliding groove that matches the support column, and the protective cover slides to above the connection point between the connecting end and the FPC flexible plate, and the inside of the support column is provided with a limiting sliding groove that matches the limiting slider.
[0014] Preferably, the side of the FPC flexible plate is provided with a mating hole that matches the locking plate, and an inclined limiting groove is provided in the mating hole. The locking plate has a sawtooth structure that extends into the FPC flexible plate, and its surface is a conical surface.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. By bringing the FPC flexible board and the connection end closer together, the FPC flexible board drives the sub-pins and mating posts to slide into the connection end. At the same time, the sub-pins first contact and press against the female pins. Due to the curved shape of the sub-pins and female pins and the elasticity of the female pins, it is easy for the sub-pins and female pins to contact and press against each other, causing the sub-pins to press against the female pins and slide to the bottom of the female pins. Meanwhile, the FPC flexible board drives the sub-pins and mating posts to continue moving, so that the mating posts contact the support plate and push the support plate to compress the telescopic spring. This causes the support plate to move downward and push the pressure post to move downward, pressing the female pins downward. This makes the female pins and sub-pins press against each other and fit together, thus making the contact between the female pins and sub-pins more reliable.
[0017] 2. By having the staff push the support column, the support column slides, causing the protective cover to slide. The protective cover slides, causing the locking plate to move out from inside the connecting end and penetrate into the FPC flexible board. An inclined limiting groove is opened in the docking hole. The plate structure of the locking plate penetrating into the FPC flexible board is serrated and the surface is conical, which facilitates the locking plate to slide tilted into the limiting groove and engage with the inside of the FPC flexible board. The locking plate tilts downward, causing the protective cover to move downward through the limiting slider and limiting spring, so that the protective cover moves downward and fits against the top of the connection between the connecting end and the FPC flexible board, thus providing dust protection for the top of the connection between the connecting end and the FPC flexible board.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] This utility model provides, for example Figure 1-6 The connection structure shown is for connecting FPC connectors, including a connection end 1, an FPC flexible plate 101 connected to the right side of the connection end 1, a docking mechanism 2 connected between the connection end 1 and the FPC flexible plate 101 and extending into the interior of the connection end 1, and a protective mechanism 3 slidably connected to the outer wall of the connection end 1 and extending into the interior of the FPC flexible plate 101.
[0029] The docking mechanism 2 includes multiple sub-pins 201. The multiple sub-pins 201 are mechanically fixed to the outer wall of the FPC flexible plate 101 near the connecting end 1 and extend into the interior of the connecting end 1. Multiple female pins 202 are mechanically fixed inside the connecting end 1 and located above the sub-pins 201. Multiple docking posts 203 are mechanically fixed to the top left side of the FPC flexible plate 101 and extend into the interior of the connecting end 1. Multiple support plates 204 are slidably connected inside the connecting end 1 and located at the bottom side of the docking posts 203. A pressing post 205 is mechanically fixed to the bottom end of the support plate 204 and fits against the top end of the female pin 202. A telescopic spring 206 is mechanically connected between the bottom end of the support plate 204 and the interior of the connecting end 1.
[0030] The protective mechanism 3 includes a support column 301, which is slidably connected to both ends of the top of the connecting end 1. A protective cover plate 302 is slidably connected to the top of the support column 301. A locking plate 303 is mechanically fixed to the bottom of the protective cover plate 302 and extends through the connecting end 1 to the interior of the FPC flexible plate 101.
[0031] Through the cooperation of the internal parts of the docking mechanism 2, the connection and fixation between the connecting end 1 and the FPC flexible plate 101 can be completed, and it is also convenient to squeeze the contact between the female pin 202 and the female pin 201, making the contact between the female pin 202 and the female pin 201 more reliable. Through the cooperation of the internal parts of the protection mechanism 3, the top of the connection between the connecting end 1 and the FPC flexible plate 101 can be protected against dust, and it is also convenient to increase the connection between the connecting end 1 and the FPC flexible plate 101.
[0032] Refer to the instruction manual appendix Figure 1-6 The protective mechanism 3 also includes a limiting slider 304, which is mechanically fixed to both ends of the outer wall of the protective cover plate 302 and slidably connected to the inner wall of the support column 301. A limiting spring 305 is mechanically fixed between the bottom end of the limiting slider 304 and the support column 301. Through the mutual cooperation between the internal parts of the protective mechanism 3, it is easy for the protective cover plate 302 to fit with the connecting end 1 and the top of the FPC flexible plate 101.
[0033] Refer to the instruction manual appendix Figure 1-6 The internal part of the connecting end 1 is provided with a socket that matches the sub-pin 201 and the mating post 203. The sub-pin 201 and the female pin 202 are curved in shape, and the female pin 202 has a certain degree of elasticity. The curved shape of the sub-pin 201 and the female pin 202 and the certain degree of elasticity of the female pin 202 facilitate the contact and compression between the sub-pin 201 and the female pin 202, and make the sub-pin 201 press the female pin 202 up and slide to the bottom of the female pin 202.
[0034] Refer to the instruction manual appendix Figure 1-6 The surface of the support plate 204 and the contact surface of the docking post 203 are both set as arc surfaces. The inside of the connecting end 1 is provided with a telescopic groove that matches the pressing post 205. The bottom end of the pressing post 205 and the top end of the female pin 202 are both set as arc surfaces. By setting the surface of the support plate 204 and the contact surface of the docking post 203 as arc surfaces, it is easy for the docking post 203 to slide into the inside of the connecting end 1 and press the support plate 204.
[0035] Refer to the instruction manual appendix Figure 1-6 The top of the connecting end 1 is provided with a sliding groove that matches the support column 301, and the protective cover plate 302 slides above the connection between the connecting end 1 and the FPC flexible plate 101. The inside of the support column 301 is provided with a limiting sliding groove that matches the limiting slider 304. The sliding groove that matches the support column 301 at the top of the connecting end 1, and the protective cover plate 302 sliding above the connection between the connecting end 1 and the FPC flexible plate 101, facilitate the sliding of the support column 301 to drive the protective cover plate 302 to slide above the connection between the connecting end 1 and the FPC flexible plate 101.
[0036] Refer to the instruction manual appendix Figure 1-6 The side of the FPC flexible board 101 is provided with a mating hole that matches the locking plate 303, and an inclined limiting groove is provided in the mating hole. The locking plate 303 has a sawtooth-shaped plate structure that penetrates into the FPC flexible board 101 and has a conical surface. The inclined limiting groove in the mating hole and the sawtooth-shaped plate structure and conical surface of the locking plate 303 that penetrate into the FPC flexible board 101 facilitate the locking plate 303 to slide obliquely into the limiting groove and engage with the inside of the FPC flexible board 101.
[0037] The working principle of this practical application is as follows:
[0038] Refer to the instruction manual appendix Figure 1-6 By bringing the FPC flexible plate 101 and the connecting end 1 closer together, the FPC flexible plate 101 causes the sub-pin 201 and the mating post 203 to slide into the connecting end 1. At the same time, the sub-pin 201 first contacts and presses against the female pin 202. Because the sub-pin 201 and the female pin 202 are curved in shape and the female pin 202 has a certain degree of elasticity, it is easy for the sub-pin 201 and the female pin 202 to contact and press against each other, causing the sub-pin 201 to press the female pin 202 up and slide towards the female pin. At the bottom of foot 202, the FPC flexible plate 101 drives the sub-pin 201 and the docking post 203 to continue moving, so that the docking post 203 contacts the support plate 204 and pushes the support plate 204 to compress the telescopic spring 206 to contract and move, so that the support plate 204 moves downward and pushes the pressing post 205 to move, so that the pressing post 205 presses the female pin 202 downward, so that the female pin 202 and the sub-pin 201 are pressed and adhered to each other, thereby making the contact between the female pin 202 and the sub-pin 201 more reliable;
[0039] Refer to the instruction manual appendix Figure 1-6 When the staff pushes the support column 301, the support column 301 slides, causing the protective cover plate 302 to slide. The protective cover plate 302 slides, causing the locking plate 303 to move out from the inside of the connecting end 1 and penetrate into the FPC flexible plate 101. An inclined limiting groove is opened in the docking hole. The plate structure of the locking plate 303 penetrating into the FPC flexible plate 101 is serrated and the surface is conical, which makes it easy for the locking plate 303 to slide obliquely into the limiting groove and lock into the inside of the FPC flexible plate 101. The locking plate 303 slides downward obliquely, causing the protective cover plate 302 to retract and move through the limiting slider 304 and the limiting spring 305, so that the protective cover plate 302 moves downward and fits against the top of the connection between the connecting end 1 and the FPC flexible plate 101, thus providing dust protection for the top of the connection between the connecting end 1 and the FPC flexible plate 101.
[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
