AI Technical Summary
During production and assembly of existing FPC/FFC connectors, the FPC/FFC scratches due to the interference fit of the ground terminals, the ground terminal does not rebound, and cannot be inserted into the slot, resulting in low yield and assembly efficiency.
An electronic connector is designed including a base, a grounding assembly and a flip cover. The grounding assembly consists of a fixing member and a limiting member, which is embedded at both ends of the base and the limiting member is embedded in the flip cover. When the flip cover is closed, the limiting member abuts the fixing member and the grounding end of the FPC/FFC, thereby avoiding the problem of excessive tight contact between the grounding member and the base.
Through this design, the situation where the two ends of FPC/FFC cannot be inserted into the slot, the production and assembly yield of electronic connectors is improved, and the assembly of employees is facilitated.

[0050] FPC / FFC connector is used to connect printed circuit board (PCB) and flexible printed circuit (FPC) or flexible flat cable (FFC) to achieve mechanical and electrical connection. Its characteristics are that one end is welded with PCB board and the other end is plugged with FPC / FFC, and it is locked and fixed by the locking structure designed on the FPC / FFC connector to maintain a certain contact reliability.
[0051] In an exemplary technology, the grounding terminal of the FPC / FFC adopts an integrated structural design. During actual production and assembly, the grounding terminal is embedded in the base and is usually pressed down by a flap to connect the grounding end of the FPC / FFC. Due to processing errors in parts, there will be an interference fit between the connection point of the grounding terminal and the bottom wall of the base slot, which can easily cause the FPC / FFC to be scratched and the grounding terminal to not rebound, or even cause there to be no gap for the two ends of the FPC / FFC to be inserted into the slot, resulting in a relatively low yield rate in the production and assembly of electronic connectors and low assembly efficiency.
[0052] In order to improve the yield rate of electronic connector production and assembly and facilitate employees to assemble, the present invention proposes an electronic connector suitable for connecting a PCB board and an FPC / FFC, etc., which is not limited here.
[0053] Reference Figures 1 to 5 In one embodiment of the present invention, the electronic connector includes a base 100, a grounding component 200 and a flip cover 300. The base 100 is formed with a slot 101 for the connecting end of the FPC / FFC10 to be plugged and adapted; the grounding component 200 includes a fixing member 210 and a limiting member 220. The fixing member 210 is embedded and installed at both ends of the base 100 and extends toward the slot 101. The fixing member 210 is used for grounding; the flip cover 300 is flippably switched between a closed position and an open position on the base 100, and the flip cover 300 is provided with a receiving cavity 301 for accommodating the limiting member 220; when the flip cover 300 is in the open position, the fixing member 210 is relatively separated from the limiting member 220; when the flip cover 300 is in the closed position, one end of the limiting member 220 abuts against the fixing member 210, and the other end of the limiting member 220 abuts against the grounding end of the FPC / FFC10.
[0054] The fixing member 210 and the limiting member 220 are split structures, the fixing member 210 is embedded at both ends of the base 100, and the limiting member 220 is embedded in the flip cover 300. The fixing member 210 and the limiting member 220 can both be made of metal material with excellent conductive properties to achieve grounding of the FPC / FFC10.
[0055] The base 100 may include a plastic base and a plurality of conductive terminals embedded therein and arranged side by side for connecting the FPC / FFC and the PCB board.
[0056] It should be noted that the limiting member 220 can be an integrated metal member (the metal member is embedded in the flip cover 300, and its two ends correspond to the positions of the two fixing members 210 in the base 100), or it can be two separate metal members respectively arranged at the two ends of the flip cover 300, or it can be formed by connecting multiple metal members. The number of limiting members 220 and accommodating cavities 301 is not limited here.
[0057] During production and assembly, the fixing member 210 can be first embedded in the two ends of the base 100 by means of snap-fitting or welding, with the grounding end exposed and the connecting end extending toward the slot 101. The limiting member 220 can then be embedded in the receiving groove of the flip cover 300 by means of snap-fitting or welding. After confirming that the installation is correct, the flip cover 300 can be installed on the base 100 to complete the assembly of the entire electronic connector.
[0058] It can be understood that the present invention provides a slot 101 for the connecting end of the FPC / FFC10 to be plugged and adapted on the base 100 of the electronic connector, the grounding assembly 200 includes a fixing member 210 and a limiting member 220, the fixing member 210 is embedded and installed at both ends of the base 100 and extends toward the slot 101, the fixing member 210 is used for grounding, and the flip cover 300 is flip-switchably arranged on the base 100 in a closed position and an open position, and the flip cover 300 is provided with a accommodating cavity 301 for accommodating the limiting member 220. When the flip cover 300 is in the open position, the fixing member 210 and the limiting member 220 are relatively separated, and when the flip cover 300 is in the open position, the fixing member 210 and the limiting member 220 are relatively separated. When the cover 300 is in the closed position, one end of the limit member 220 abuts against the fixing member 210, and the other end of the limit member 220 abuts against the grounding end of the FPC / FFC10. During production and assembly, this avoids the situation in which the grounding member abuts too tightly against the base 100, resulting in the two ends of the FPC / FFC10 being unable to be inserted into the slot 101. The present invention can open the flip cover 300 to relatively disengage the limit member 220 from the fixing member 210, then insert the FPC / FFC10 into the slot 101 of the base 100, and finally close the flip cover 300, thereby improving the yield rate of electronic connector production and assembly and facilitating assembly by employees.
[0059] In order to improve the installation efficiency of the fixing member 210 and enhance the connection strength between the fixing member 210 and the base 100, refer to Figure 6 In one embodiment, the fixing member 210 includes a main body 211, a grounding arm 212, a first fixing arm 213 and a first connecting arm 214. The main body 211 is embedded in the base 100; the grounding arm 212 is arranged on the side of the main body 211 away from the flip cover 300 and is used for grounding; the first fixing arm 213 is arranged on the main body 211 and extends along the width direction of the base 100, and the first fixing arm 213 is plugged and fixed in the base 100; the first connecting arm 214 is arranged on the other side of the main body 211 away from the grounding arm 212 and extends, and the first connecting arm 214 is used to abut against the limit member 220.
[0060] In this embodiment, the angle between the ground arm 212 and the body 211 can be set at 90°; the first fixed arm 213 and the ground arm 212 can be set in parallel; the angle between the ground arm 212 and the body 211 can be set at 90°. In this way, a higher connection strength is achieved, making the entire electronic connector more stable. Of course, in some other embodiments, for the purpose of facilitating installation or improving the clamping strength, other shapes of fixing members 210 can also be set, and the angles between the above-mentioned parts are not limited here.
[0061] Further, refer to Figure 6 In this embodiment, a flange 215 may be provided at one end of the first connecting arm 214 close to the limiting member 220 , and the flange 215 is used to limit the relative separation of the fixing member 210 from the base 100 along the width direction of the base 100 .
[0062] It should be noted that there can be a smooth transition between the flange 215 and the first connecting arm 214 to avoid sharp edges from cutting employees during production and assembly, thereby reducing safety risks.
[0063] In order to improve the installation efficiency of the stopper 220 and enhance the connection strength between the stopper 220 and the flip cover 300, refer to Figure 7 In one embodiment, the limiting member 220 includes a main body 221, a second fixed arm 222, a second connecting arm 223 and a limiting arm 224. The main body 221 is embedded in the accommodating cavity 301 of the flip cover 300; the second fixed arm 222 is arranged on one side of the middle part of the main body 221, and the second fixed arm 222 is extended along the width direction of the base 100 and is inserted and fixed in the accommodating cavity 301; the second connecting arm 223 is arranged at one end of the main body 221 close to the fixing member 210, and is used to abut against the first connecting arm 214 of the fixing member 210; the limiting arm 224 is arranged on the other end of the main body 221 facing away from the second connecting arm 223, and is used to abut against the grounding end of the FPC / FFC10 and limit the movement of the FPC / FFC10.
[0064] In this embodiment, the abutting end of the second connecting arm 223 can be arranged in a "V" shape; the abutting end of the limiting arm 224 can also be arranged in a "V" shape. Such an arrangement can facilitate the FPC / FFC10 to be clamped in the slot 101, and its grounding end is stably connected to the limiting member 220, thereby achieving grounding of the FPC / FFC10.
[0065] It should be noted that, in some embodiments, the angle between the second connecting arm 223 of the stopper 220 and the main body 221, and the angle between the stopper arm 224 and the main body 221 can be the same or different, and the "V"-shaped structures at the ends of the two can be exactly the same or different. Through reasonable structural design, the overall connection strength can be more stable and the assembly can be more convenient. Among them, when the structures of the second connecting arm 223 and the stopper arm 224 are not exactly the same, the structures of the stopper 220 at both ends of the flip cover 300 can be mirror-imaged, and the two fixing members 210 respectively connected thereto can also be mirror-imaged. The specific shapes of the fixing members 210 and the stopper 220 are not limited here.
[0066] In order to further enhance the connection strength between the stopper 220 and the flip cover 300, refer to Figure 7 In this embodiment, the second fixed arm 222 can be set in a toothed plate shape, and the shape of the accommodating groove of the flip cover 300 corresponds to the shape of the second fixed arm 222. The toothed plate-shaped second fixed arm 222 is used to limit the relative separation of the limiting member 220 from the accommodating cavity 301.
[0067] refer to Figures 3 to 5 In some embodiments, the flip cover 300 is provided with a rotating shaft 302 at both ends, the base 100 is provided with an opening for accommodating the flip cover 300, and the positions of the two ends of the opening corresponding to the rotating shaft 302 are provided with a rotating shaft insertion hole 102, and the rotating shaft 302 is inserted into the rotating shaft insertion hole 102, so that the flip cover 300 can be flipped and switched on the base 100 between the closed position and the open position. In this way, the flip cover 300 and the base 100 are flipped and connected.
[0068] In order to lock the flip cover 300 and the pressed FPC / FFC10, in the present embodiment, protrusions 303 are provided at both ends of the flip cover 300 near the rotating shaft 302, and snap-fitting grooves 103 are provided at positions corresponding to the protrusions 303 on both sides of the opening of the base 100; when the flip cover 300 is in the closed position, the protrusions 303 are snapped into the grooves 103 to lock the flip cover 300 and the base 100.
[0069] The present invention also proposes a circuit assembly, which includes an FPC / FFC, a PCB board and an electronic connector connecting the FPC / FFC and the PCB board. The specific structure of the electronic connector refers to the above embodiment. Since the circuit assembly proposed by the present invention includes all schemes of all embodiments of the above electronic connector, it has at least the same technical effect as the electronic connector, which will not be elaborated here one by one.
