Description

Technical Field

[0001] This application relates to the field of FPC technology, and more particularly to an FPC connector and an FPC. Background Technology

[0002] An FPC is a highly reliable and flexible printed circuit board. It is made of a flexible insulating substrate, on which conductive lines are formed through processes such as etching, enabling electrical connections between electronic components. An FPC connector is an electronic connector used to connect FPCs and other electronic components (such as circuit boards, electronic components, etc.) through insertion.

[0003] Existing FPC connectors achieve electrical connection through the insertion structure of male and female connectors. This structure usually has a plastic clip on the male connector. The plastic clip deforms and then snaps into the female connector. When unlocking, pressing the plastic clip will disengage it from the slot on the female connector, thus separating the male and female connectors.

[0004] However, traditional plastic clips undergo continuous deformation due to repeated insertion and removal during long-term use. Because plastic materials have fatigue limits, they are prone to breakage after repeated bending and compression. Moreover, with the increase in the number of uses, the elasticity of the plastic gradually decreases, causing the clips to fail to return to their original position properly, resulting in unstable connections and affecting usability.

[0005] Therefore, there is an urgent need for an FPC connector and an FPC to solve the above problems.

[0006] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Utility Model Content

[0007] The main objective of this application is to provide an FPC connector and an FPC that solves the problem that existing FPC connectors are prone to damage and affect use as the usage time increases.

[0008] To achieve the above objectives, this application provides an FPC connector, including a first connector and a second connector. The first connector and the second connector are clamped together by a clamping assembly. The clamping assembly includes a fixing plate, a wedge block, and a spring. The fixing plate is connected to the first connector, and the wedge block is connected to the fixing plate through the spring. One end of the wedge block passes through the first connector and is connected to a slot on the second connector.

[0009] As a preferred embodiment of this application, it also includes a guide rod and a pull ring. The wedge block is provided with a guide rod, and one end of the guide rod passes through the fixing plate and is connected to the pull ring.

[0010] As a preferred embodiment of this application, it further includes a first anti-mistake mechanism and a second anti-mistake structure, wherein the first connector is provided with the first anti-mistake structure and the second connector is provided with the second anti-mistake structure, and the first anti-mistake structure cooperates with the second anti-mistake structure.

[0011] As a preferred embodiment of this application, the first connector is provided with a mounting groove, a first conductor layer is provided in the mounting groove, and a plurality of pins are provided on the first conductor layer, with a plurality of the pins extending outward through the first connector.

[0012] As a preferred embodiment of this application, the second connector is provided with a placement groove, and a first wedge-shaped structure is provided in the placement groove.

[0013] As a preferred embodiment of this application, it also includes a contact surface, wherein the bottom of the second connector has a contact surface that penetrates the placement groove.

[0014] As a preferred embodiment of this application, it also includes foot pads, and a plurality of foot pads are provided on the bottom of the first connector.

[0015] An FPC, applicable to the aforementioned FPC connector, includes a flexible insulating board, a second conductor layer disposed on the flexible insulating board, and beveled angles on both sides of the flexible insulating board near the second conductor layer, with a second wedge structure disposed at the beveled angles.

[0016] This application provides an FPC connector that utilizes a wedge block and a spring to achieve quick installation and disassembly of a first connector and a second connector. During installation, simply insert the second connector into the first connector, causing the wedge block to engage with the slot in the second connector, thus achieving a secure connection. For unlocking, the wedge block and spring are moved again to compress the connector, enabling quick disassembly. This wedge block and spring clamping method offers high strength and toughness. During long-term use, the wedge block will not break like plastic clamps, and the spring maintains good elasticity during repeated expansion and contraction. Under the action of the spring, the wedge block can continuously and stably clamp the second connector. Compared to directly using plastic clamps for deformation clamping, the connection method adopted in this application has a longer service life and a more stable connection.

[0028] Please refer to Figure 1 , Figure 2In one embodiment, an FPC connector includes a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 are clamped together by a clamping assembly 3. The clamping assembly 3 includes a fixing plate, a wedge block and a spring. The fixing plate is connected to the first connector 1, and the wedge block is connected to the fixing plate by the spring. One end of the wedge block passes through the first connector 1 and is connected to the slot 201 on the second connector 2.

[0029] Preferably, in this embodiment, the wedge block and the spring are made of metal;

[0030] It is understood that the FPC connector provided in this application utilizes a wedge block and a spring to achieve quick installation and disassembly of the first connector 1 and the second connector 2. During installation, simply insert the second connector 2 into the first connector 1, causing the wedge block to engage with the slot 201 in the second connector 2, thus achieving a secure connection between the first connector 1 and the second connector 2. During unlocking, quick disassembly can be achieved by moving the wedge block and compressing the spring again. Since the wedge block and spring are made of metal, which possesses high strength and toughness, the metal wedge block will not break during long-term use, unlike plastic wedge blocks. The spring maintains good elasticity during multiple extensions and retractions, and the wedge block can continuously and stably clamp the second connector 2 under the action of the spring. Compared with the method of directly using the deformation of the plastic block to clamp, the connection method adopted in this application has a longer service life and a more stable connection. At the same time, when the second connector 2 is inserted into the first connector 1, since the connection method between the wedge block and the slot 201 is relatively simple and direct, as long as the second connector 2 is inserted into the roughly correct position of the first connector 1, the wedge block can automatically clamp into the slot 201 on the second connector 2 under the action of the spring. This structure has relatively low requirements for insertion accuracy and is more convenient to operate.

[0031] Specifically, please refer to Figure 6 Based on the above embodiments, it also includes a guide rod 4 and a pull ring 5. The wedge block is provided with a guide rod 4, and one end of the guide rod 4 passes through the fixing plate and is connected to the pull ring 5.

[0032] It is understandable that by setting the guide rod 4, the wedge block can be guided during its movement. At the same time, by setting the pull ring 5, the user can easily pull the wedge block to unlock it during use.

[0033] Specifically, please refer to Figure 2 , Figure 4 Based on the above embodiments, it also includes a first anti-mistake mechanism and a second anti-mistake structure 205. The first connector 1 is provided with the first anti-mistake structure 101, and the second connector 2 is provided with the second anti-mistake structure 205. The first anti-mistake structure 101 and the second anti-mistake structure 205 cooperate with each other.

[0034] It can be understood that the first foolproof structure 101 is provided with a protrusion on one side of the first connector 1, and the second foolproof structure 205 is provided according to the protrusion on the first foolproof structure 101, so as to achieve the effect of quick and accurate installation of the first connector 1 and the second connector 2.

[0035] Specifically, please refer to Figure 2 , Figure 6 Based on the above embodiments, the first connector 1 is provided with a mounting groove 102, a first conductor layer 103 is provided in the mounting groove 102, and a number of pins are provided on the first conductor layer 103, with the pins extending outward through the first connector 1.

[0036] It is understood that the mounting slot 102 is used to install the second connector 2. After installation, the first conductor layer 103 is connected to the FPC, and then connected to the circuit board 10 through the pins.

[0037] Specifically, please refer to Figure 2 , Figure 4 , Figure 5 Based on the above embodiments, the second connector 2 is provided with a placement groove 202, and a first wedge structure 204 is provided in the placement groove 202.

[0038] It is understandable that the placement slot 202 is used to place the FPC, and the FPC can be quickly installed by setting the first wedge structure 204.

[0039] Specifically, please refer to Figure 3 Based on the above embodiments, it also includes a contact surface 203, and the bottom of the second connector 2 is provided with a contact surface 203 that passes through the placement groove 202.

[0040] It is understandable that by opening the contact surface 203, after the FPC and the second connector 2 are installed, the conductor layer on the FPC can be exposed, which facilitates the connection with the first connector 1.

[0041] Specifically, please refer to Figure 3 Based on the above embodiments, it also includes foot pads 8, and a plurality of foot pads 8 are provided at the bottom of the first connector 1.

[0042] It is understandable that by setting the foot pads 8 to provide support for the first connector 1, it is possible to ensure that there is a gap between the pins and the contact surface 203 when the first connector 1 is placed horizontally, which can effectively prevent the pins from being damaged or contaminated.

[0043] Please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6An FPC, applicable to the aforementioned FPC connector, includes a flexible insulating plate 6, a second conductor layer 9 disposed on the flexible insulating plate 6, and beveled angles opened on both sides of the flexible insulating plate 6 near the second conductor layer 9, with a second wedge structure 7 disposed at the beveled angles.

[0044] It is understood that the second wedge block structure is used to engage with the first wedge structure 204. In use, the end with the second wedge structure 7 is inserted into the second connector 2. The second wedge structure 7 deforms after contacting the first wedge structure 204 during insertion. Then, the installation of the FPC and the second connector 2 is achieved through the first wedge structure 204. At the same time, the second conductor layer 9 is used to conduct electricity with the first conductor layer 103. The second conductor layer 9 is connected to the first conductor layer 103 after being connected to the first connector 1 through the contact surface 203.

[0045] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, apparatus, article, or method that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, apparatus, article, or method. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, apparatus, article, or method that includes that element.
