Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and more particularly to a flexible circuit board connector for high current applications. Background Technology

[0002] Ribbon cable connectors, or cable plug connectors, are common electronic components, typically used to connect blocked or isolated circuits, allowing current to flow between them to achieve their intended functions. They also serve as a bridge for signal transmission and reception. FPC (Flexible Printed Circuit) connectors are a common type of plug-in connector, usually used to connect FPC ribbon cables. They primarily use a single-pin terminal structure for transmitting small currents.

[0003] However, with the increasing functionality of electronic devices, some existing ribbon cable connectors require additional high-current contact terminals (such as those handling currents exceeding 0.5A). In existing technology, to meet these high-current requirements, the common practice is to increase the width of the entire contact terminal. This wide contact terminal structure is often only suitable for installation at both ends of the base, applicable when the main current is high at both ends. When all terminals of the entire ribbon cable connector require high-current transmission, the wide contact terminals often occupy a large installation area, resulting in a larger terminal spacing, which cannot meet the high-density mating requirements of the entire ribbon cable (flexible printed circuit board, FPC).

[0004] Therefore, existing technologies still need improvement and development. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a flexible circuit board connector for high current, which solves the problem that the high current terminals in the prior art occupy a large area and cannot meet the high-density mating requirements of ribbon cable connectors.

[0010] Optionally, a first clearance area is provided on the first terminal, and the first clearance area is located below the first lower clamping member to enhance the elastic performance of the first lower clamping member; A second clearance groove is provided on the second terminal. The second clearance groove is located below the second lower clamping member, which enhances the elasticity of the second lower clamping member.

[0011] Optionally, the first electrode portion and the second electrode portion are offset in the front-rear direction of the base.

[0012] Optionally, the first terminal also includes a first upper connector, through which the flip cover is rotatably connected to the base; Or / and, The second terminal also includes a second upper connector, through which the flip cover can be flipped and connected to the base.

[0013] Optionally, when the flip cover is connected to the base via the second upper connector, the first upper connector includes a guide arm, and the second upper connector has a slot. The flip cover includes: a hinge, which is movably positioned in a slot; The pressure-bearing slot has a guide arm inserted into it. An eccentric pressure table, which is eccentric to the central axis of the rotating shaft; By rotating the flip cover, the rotating shaft moves within the locking slot, causing the bottom surface of the pressure slot to rotate to the lower surface of the guide arm, thereby locking and limiting the flip cover. The eccentric pressure table then presses down on the flexible circuit board after rotating.

[0014] Optionally, the base includes: an insulating base; The first insertion slot has an insertion port located on the front side of the insulating base and is used to allow the first terminal to be inserted into and confined within the insulating base.

[0022] like Figure 1 , Figure 5 As shown, this embodiment proposes a flexible circuit board connector for high current applications, used for detachable docking with a flexible circuit board 400 (FPC, ribbon cable) to achieve circuit continuity. The flexible circuit board connector mainly includes: a base 100, multiple terminal assemblies 200, and a flip cover 300. The base 100 is primarily an insulating base with a certain width, and its multiple terminal assemblies 200 are arranged at intervals along the width direction. For ease of structural description, the width direction of the base 100 is considered the left-right direction; the direction in which the base 100 is used to insert the flexible circuit board 400 (FPC, ribbon cable) is considered the front, and the opposite direction is considered the rear; the thickness direction of the base 100 is considered the up-down direction. All structures described below will be based on this reference.

[0023] like Figure 1 , Figure 2 , Figure 5 As shown, multiple terminal assemblies 200 are arranged side-by-side at intervals on the base 100 in a left-right direction, and are detachably connected to the contacts 410 of the flexible circuit board 400 via the multiple terminal assemblies 200. A flip cover 300 is movably connected to the base 100, and flipping the flip cover 300 locks or releases the connected flexible circuit board 400 from the base 100. For example, flipping the flip cover 300 downwards and pressing it onto the base 100 presses down and locks the flexible circuit board 400 onto the base 100, causing the contacts 410 of the flexible circuit board 400 to be in close contact with the multiple terminal assemblies 200 and conduction. Flipping the flip cover 300 upwards moves the front end of the flip cover away from the base 100, thereby releasing the flexible circuit board 400 below from the base 100. The user can then pull the flexible circuit board 400 out of the base 100, separating the contacts 410 from the multiple terminal assemblies 200.

[0024] like Figure 2 , Figure 3As shown, each terminal assembly 200 includes at least one first terminal 210 and at least two second terminals 220. The at least two second terminals 220 are located on the left and right sides of at least one first terminal 210, and both the first terminal 210 and the second terminal 220 extend to the outside of the base 100 and are electrically connected to the same electrical connection electrode. Specifically, the first terminal 210 and the second terminal 220 can both be thin metal sheets, and their left and right widths can be the same as those of ordinary standard terminals (PINs), for example, the left and right widths can be about 0.1 mm (e.g., 0.08 mm). This allows for the transmission of large currents without increasing the left and right width of the terminals. The first terminal 210 and the second terminal 220 are located in different insertion directions of the base 100. For example, the first terminal 210 is inserted into the base 100 from the front side for installation, and the second terminal 220 is inserted into the base 100 from the rear side for installation. The base 100 ensures that the spacing between each terminal assembly 200 is the same, and the spacing between the first terminal 210 and the second terminal 220 in each terminal assembly 200 is also the same. In actual mating, at least one first terminal 210 and at least two second terminals 220 in each terminal assembly 200 are mated with a contact 410 of the flexible circuit board 400 to transmit current.

[0025] like Figure 5 As shown, the flexible circuit board connector in this embodiment employs a multi-terminal parallel structure with second terminals 220 arranged on both sides of the first terminal 210, jointly connecting to a single contact 410 of the FPC (flexible circuit board 400), utilizing multi-point contact to shunt large currents. Compared to the traditional solution of simply widening the width of a single terminal, this design achieves high current transmission without increasing the overall width of the terminal, significantly saving installation space in the base 100, perfectly adapting to the high-density docking requirements of the FPC, and simultaneously, multi-point contact effectively reduces contact resistance and improves the stability of high current transmission.

[0026] like Figure 2 , Figure 6 , Figure 7 As shown, in some embodiments, the base 100 specifically includes: an insulating base 110, a first insertion slot 120, and a second insertion slot 130. The insertion port of the first insertion slot 120 is located on the front side of the insulating base 110, for inserting and confining the first terminal 210 within the insulating base 110; the insertion port of the second insertion slot 130 is located on the rear side of the insulating base 110, for inserting and confining the second terminal 220 within the insulating base 110. The bidirectional design of the first insertion slot 120 and the second insertion slot 130 allows the insulating base 110 to stably accommodate terminals from different directions, enabling simultaneous installation from both sides during assembly, resulting in a compact structure and high assembly efficiency.

[0027] like Figure 3 , Figure 6 , Figure 7 As shown, the first terminal 210 further includes a first welding portion 215 with a stop surface 2151. The first welding portion 215 protrudes downwards, and the stop surface 2151 is formed on its rear side. After the first terminal 210 is inserted into the first insertion groove 120 from front to back, the stop surface 2151 moves rearward and abuts against the front side of the insulating base 110, thereby limiting the position of the first terminal 210 inserted into the first insertion groove 120. The second terminal 220 includes a second welding portion 225 with a insertion groove 2251. The opening of the insertion groove 2251 faces forward. After the second terminal 220 is inserted into the second insertion groove 130 from back to front, the insertion groove 2251 moves rearward and inserts into the rear side of the insulating base 110, thereby cooperating with the rear end of the insulating base 110 to limit the position of the second terminal 220 inserted into the second insertion groove 130. The limiting design of the stop surface 2151 of the first terminal 210 and the insertion slot 2251 of the second terminal 220 ensures that the first terminal 210 and the second terminal 220 can be accurately positioned during assembly, ensuring the consistency of the contact position between the first terminal 210 and the second terminal 220 and the FPC contact 410, avoiding excessive local stress or poor contact caused by terminal assembly tolerance, and improving the product yield and service life.

[0028] like Figure 3 , Figure 4 As shown, in some embodiments, both the first soldering portion 215 and the second soldering portion 225 are used for soldering and fixing to the printed circuit board 230 (PCB). The first terminal 210 and the second terminal 220 are electrically connected to the same electrical connection electrode through the printed circuit board 230 (PCB). The printed circuit board 230 is provided with multiple pads and a conductive layer 233. The multiple pads are electrically connected to each other through the conductive layer 233. The first terminal 210 and the second terminal 220 are respectively soldered to the corresponding pads. Both the first soldering portion 215 and the second soldering portion 225 protrude downwards, so that the printed circuit board 230 is located below the base 100 and extends in the front-back direction, so that the first soldering portion 215 and the second soldering portion 225 are both soldered and fixed to the pads at different positions on the printed circuit board 230 (PCB) to achieve electrical connection.

[0029] like Figure 3 , Figure 4As shown, the pad soldered to the first terminal 210 is the first pad 231, and the pad soldered to the second terminal 220 is the second pad 232. The first pad 231 and the second pad 232 are staggered in the front-rear direction of the base 100. In the specific structure, the conductive layer 233 is copper foil, and the surface of the printed circuit board 230 needs to be insulated and covered with copper foil. The first pad 231 is located at the front end of the printed circuit board 230, and the two second pads 232 are located at the rear end of the printed circuit board 230. The front and rear pads are connected by copper foil. The printed circuit board 230 internally bridges the terminals with different insertion directions, realizing that terminals inserted in different directions form a unified electrical connection on the printed circuit board 230. The staggered distribution design of the pads, combined with the differentiated insertion of the terminals in the front-rear direction of the base 100, effectively avoids the risk of electrical short circuit between adjacent terminal assemblies 200, and improves the overall insulation safety and wiring flexibility of the connector.

[0030] like Figure 3 , Figure 7 , Figure 8 As shown, in some embodiments, the first terminal 210 specifically includes a first lower latch 211, on which a first electrode portion 212 is integrally disposed; the first electrode portion 212 protrudes upward. The second terminal 220 includes a second lower latch 221, on which a second electrode portion 222 is integrally disposed, protruding upward. The first lower latch 211 is located between the two second lower latches 221 on both sides. In the pressed-down state of the flip cover 300, the first electrode portion 212 abuts against the electrode of the flexible circuit board 400 through the elasticity of the first lower latch 211, and the second electrode portion 222 abuts against the electrode of the flexible circuit board 400 through the elasticity of the second lower latch 221. The cooperation between the first lower latch 211 and the two second lower latches 221 on both sides forms a multi-point elastic abutment structure, and the stable pressing of the contacts 410 of the FPC is ensured by the cooperation and pressing down of the flip cover 300. The first electrode portion 212 and the second electrode portion 222 are not in the same position in the front-rear direction, so that the first electrode portion 212 and the second electrode portion 222 are misaligned in the front-rear direction of the base 100. The misaligned electrode structure further increases the creepage distance and improves the electrical safety performance under high current conditions.

[0031] like Figure 5 As shown, correspondingly, the contact 410 on the flexible circuit board 400 has a certain front-to-back length and width, so as to cover at least one first electrode portion 212 and at least two second electrode portions 222 of a terminal assembly 200.

[0032] like Figure 3 , Figure 7 , Figure 8As shown, further, a first clearance area 213 is provided on the first terminal 210, located below the first lower clamping member 211 to enhance its elastic performance; a second clearance groove 223 is provided on the second terminal 220, located below the second lower clamping member 221 to enhance its elastic performance. In the specific structure, the front part of the first lower clamping member 211 abuts against the bottom surface of the first insertion groove 120 and is effectively supported by the first insertion groove 120. A certain distance is formed between the rear part of the first lower clamping member 211 and the bottom surface of the first insertion groove 120. This gap space is the first clearance area 213. In this way, the first lower clamping member 211 forms a cantilever structure, which is conducive to generating elastic deformation.

[0033] like Figure 3 , Figure 6 As shown, a second clearance groove 223 is directly formed on the second terminal 220, thereby forming a second lower retainer 221 on the upper part of the second clearance groove 223 and a support arm for the second terminal 220 on the lower part of the second clearance groove 223. The support arm of the second terminal 220 is inserted into the bottom surface of the second insertion groove 130 to limit and support the second terminal 220. The front end of the second lower retainer 221 above the second clearance groove 223 is connected to the support arm, while the rear end is suspended, which facilitates elastic deformation. The clearance area design provides sufficient deformation space for the terminal, ensuring that the terminal has excellent elastic recovery force. Even under long-term high-current heating environment, it can maintain stable positive contact pressure and prevent poor contact.

[0034] like Figure 3 , Figure 7 , Figure 8 As shown, in some embodiments, the first terminal 210 further includes a first upper connector 214, the front end of which is fixed to the first lower clip 211 by a bent section, thereby forming an integral, generally U-shaped structure for the entire first terminal 210. The flip cover 300 is rotatably connected to the base 100 via the first upper connector 214.

[0035] like Figure 3 , Figure 6 As shown, or alternatively, the second terminal 220 also includes a second upper connector 224, the front end of which is connected to the second lower clip 221 and the support arm via a bent section. This results in the entire second terminal 220 forming a generally U-shaped integrated structure. The flip cover 300 is rotatably connected to the base 100 via the second upper connector 224.

[0036] By adopting the above method, the positions of the first terminal 210 and the second terminal 220 can be changed, which can also solve the technical problem.

[0037] like Figure 6 , Figure 7 , Figure 8As shown, or, the flip cover 300 achieves its flipping function through the combined action of the first upper connector 214 and the second upper connector 224. Specifically, when the flip cover 300 is connected to the base 100 via the second upper connector 224, the first upper connector 214 includes a guide arm 2141, and the second upper connector 224 has a locking groove 2241. The flip cover 300 specifically includes a rotating shaft 310, a pressure-receiving slot 320, and an eccentric pressure platform 330. The rotating shaft 310 is movably disposed within the locking groove 2241, the guide arm 2141 is inserted into the pressure-receiving slot 320, and the eccentric pressure platform 330 is eccentric to the central axis of the rotating shaft 310. When the flexible circuit board 400 needs to be locked, the flip cover 300 is rotated downwards. During the downward and backward rotation of the flip cover 300, the rotating shaft 310 moves within the locking groove 2241, rotating the bottom surface of the pressure-receiving groove 320 to the lower surface of the guide arm 2141, thereby locking and limiting the flip cover 300. The eccentric pressure table 330 then presses down on the flexible circuit board 400 after rotation. When the flexible circuit board 400 needs to be released, the flip cover 300 is pushed upwards. During the upward and forward rotation of the flip cover 300, the rotating shaft 310 moves within the locking groove 2241, rotating the bottom surface of the pressure-receiving groove 320 to above the guide arm 2141. The eccentric pressure table 330 rotates and maintains a certain gap with the flexible circuit board 400, thereby allowing the flexible circuit board 400 to be pulled out from the base 100.

[0038] like Figure 6 , Figure 7 , Figure 8 As shown, through the combined action of the first upper connector 214 and the second upper connector 224, the upper connector of the terminal itself is cleverly utilized as the hinge and limiting reference of the flip cover 300. The eccentric pressure table 330 design enables the flip cover 300 to generate a downward pressing force during rotation, ensuring that the FPC is firmly pressed onto the terminal; at the same time, the cooperation between the guide arm 2141 and the pressure slot 320 realizes the self-locking function after the flip cover 300 is closed, preventing the flip cover 300 from accidentally popping open under vibration or external force, and ensuring the mechanical connection reliability during high current transmission.

[0039] It should be understood that the application of this application is not limited to the examples above.
