Specifically, the first side of the metal terminal 1 is provided with an insertion port for inserting the flat conductor 4, and the metal terminal 1 has a plurality of contact arms 11 arranged in parallel, and the plurality of contact arms 11 are arranged along the width direction of the flat conductor 4, and the plurality of contact arms 11 are used to electrically connect the flat conductor 4; wherein, the flat conductor 4 is inserted into the metal terminal 1 from the insertion port and forms an electrical connection with the contact arm 11. There is a situation where signal conduction interference exists in the flat conductor connector, and the conducted interference is transmitted through the conductor, affecting the equipment directly or indirectly connected to the interference source; isolation is achieved between two adjacent contact arms 11 by a part of the terminal body 13, that is, the two adjacent conductors are isolated and shielded, which can achieve an anti-interference effect (such as Figure 8 ). The grounding spring 5 is provided on the metal terminal 1 and faces the plug interface, and the grounding spring 5 extends along the width direction of the flat conductor 4; the grounding spring 5 has a plurality of contact springs 52 arranged in parallel, and after the flat conductor 4 is inserted into the metal terminal 1 and electrically connected to the contact arm 11, the contact spring 52 presses and fixes the flat conductor 4. The grounding spring 5 can prevent the metal terminals 1 from interfering with each other and the external environment from interfering with the flat conductor connector; specifically, there are situations in which the metal terminals 1 interfere with each other and external interference exists in the flat conductor connector, and the flat conductor connector may be interfered with by the magnetic field generated by external high-power equipment, space electromagnetic waves, external high voltage or interference caused by power supply insulation leakage. Through the reasonable grounding design of the grounding spring 5, the common impedance coupling interference can be eliminated, the circuit can be prevented from being affected by the magnetic field and the ground potential difference, an electrostatic discharge channel can be provided, and electromagnetic compatibility can be improved to achieve an anti-interference effect. Furthermore, the lock 3 is rotatably connected to the metal terminal 1; the lock 3 has a lock spring 31, which is used to press the flat conductor 4 in the fixed plug interface when the lock 3 is pressed down, and the lock 3 can be grounded to prevent interference (the principle is the same as above); wherein, the lock 3 can be released when it is lifted up (such as Figures 8-10In addition, in the flat conductor connector, the various components of the metal terminal 1 and its multiple contact arms 11, the grounding spring 5 and its contact spring 52, and the lock 3 are reasonably coordinated, arranged, and wired, which can reduce the propagation path of interference, reduce the impact of interference, and achieve an anti-interference effect.

[0054] like Figure 1 In one embodiment shown, the flat conductor connector includes: PCB 2. PCB 2 is a board formed by patterning conductive copper foil on the surface of an insulating material (such as glass fiber, epoxy resin, etc.) to form electrical connections between electronic components. Its main function is to achieve electrical connections between electronic components and to support and fix the electronic components on the board. PCB 2 is provided at the bottom of the metal terminal 1; PCB 2 is used to connect the metal terminal 1 and the grounding spring 5; wherein each contact arm 11 is electrically connected to PCB 2; and the grounding spring 5 is electrically connected to PCB 2. Soldering is usually used for the electrical connection with PCB 2; correspondingly, there are contact points / welding points on the grounding spring 5 and the contact arm 11.

[0055] like Figure 1 、 2 In one embodiment shown in Figures , 8, and 9, the metal terminal 1 includes: a terminal body 13 and a plurality of contact arms 11. The terminal body 13 has a plurality of slots arranged in parallel along the width direction; the plurality of contact arms 11 are snapped into the slots, and each contact arm 11 corresponds to a slot. In other words, the contact arm 11 is arranged in the slot, and the slot isolates the contact arm 11. The slot prevents the arranged plurality of contact arms 11 from interfering with each other when the flat conductor connector transmits signals. At the same time, this can reduce the size of the metal terminal 1, while achieving good electrical contact of the contact arm 11, and further achieving stable and uniform current flow.

[0056] like Figure 2 、 5 In one embodiment shown, each contact arm 11 includes: a first connecting arm 111 and a second connecting arm 112. The first connecting arm 111 has a plurality of contact points for electrically connecting to the back side of the flat conductor 4; the contact points form contact on the back side / bottom side of the flat conductor 4. The second connecting arm 112 is provided at the first end of the first connecting arm 111; the second connecting arm 112 is provided with a welding point, and the welding point is welded on the PCB 2. Preferably, each contact arm 11 also includes a third connecting arm 113; the third connecting arm 113 is provided at the first end of the first connecting arm 111; the third connecting arm 113 is provided above the first connecting arm 111, and an opening connected to the plug interface is formed between the third connecting arm 113 and the first connecting arm 111, and the opening is used for the flat conductor 4 to be inserted (such as Figure 2). The protruding end of the third connecting arm 113 is inserted into the terminal body 13, preferably inserted into the crossbeam 12 on the terminal body 13; wherein, the crossbeam 12 is provided above the plug-in interface of the metal terminal 1 and is an integrally formed structure with the metal terminal 1; specifically, the crossbeam 12 is integrally formed with the terminal body 13. Each third connecting arm 113 is crimped onto the rotating shaft body; the two ends of the rotating shaft 331 are inserted into the shaft mounting holes of the support arms 54 on the grounding spring body 51; in this way, the grounding spring 5 can be connected in rotation. Among them, a through notch is preferably provided on the shaft mounting hole. In this case, the shaft mounting hole is an oblong hole with one end passing through. The third connecting arm 113 cooperates with the rotating shaft 331 to rotate the rotating shaft 331 in the oblong hole, so that the contact arm 11 can be easily disassembled and assembled. Of course, the shaft mounting hole can also be set as a round hole or other shapes that are compatible with the rotating shaft 331.

[0057] like Figure 3 、 5 In one embodiment shown, the grounding spring 5 includes a grounding spring body 51. The grounding spring body 51 is clipped onto the crossbeam 12 and secured thereto. Multiple contact springs 52 are attached to the grounding spring body 51 to form an integral structure. The contact springs 52 are preferably three in number, evenly spaced apart. The contact springs 52 preferably extend toward the second side of the metal terminal 1, extending into the insertion port and crimping the flat conductor 4 therein.

[0058] like Figure 5 In the illustrated embodiment, both ends of the grounding spring body 51 pass through the metal terminal 1 and form welded ends. Specifically, the ends of the grounding spring body 51 extend downward through the terminal body 13 and extend beyond the bottom surface of the terminal body 13 to form flanges 53 with weld points. The flanges 53 and crossbars 12 securely connect the grounding spring body 51 to the terminal body 13.

[0059] like Figure 2 、 10 In the illustrated embodiment, the grounding spring body 51 is provided with a support arm 54 extending toward the second side of the metal terminal 1. The support arm 54 defines a shaft mounting hole. The shaft mounting hole is configured to receive the end of the rotating shaft 331 for rotational engagement. The shaft mounting hole can be a circular hole or an oblong hole, with a through-notch formed at the first end of the oblong hole.

[0060] like Figure 6-10In one embodiment shown, the lock 3 includes: a lock body 33 and a lock spring 31. The lock body 33 has a rotating shaft 331. The lock spring 31 is arranged on the lock body 33; the lock spring 31 is provided with a plurality of crimping springs 32 arranged in parallel along the width direction, and the crimping springs 32 extend from the openings on the lock body 33. Preferably, the lock spring 31 is embedded in the lock body 33, and only the crimping springs 32 extend out from the openings on the lock body 33 to play an isolation and shielding effect. Preferably, there are three crimping springs 32, and the three crimping springs 32 are evenly spaced. Among them, the lock body 33 and the metal terminal 1 are fixed by means of a protrusion 332 that is snapped into a recessed hole. Preferably, a protrusion 332 is provided at each end of the lock body 33, and recessed holes are provided on both sides of the terminal body 13 corresponding to the protrusions 332. When the lock body 33 is pressed down, the crimping spring 32 of the lock spring 31 presses against the front surface of the flat conductor 4 to fix the flat conductor 4 to ground, further preventing the metal terminals 1 from interfering with each other and the external environment from interfering with the flat conductor connector; at this time, the protrusion 332 is inserted into the recessed hole, keeping the lock body 33 pressed down. Lifting the lock body 33 to release the protrusion 332 can unlock the lock 3, and the crimping spring 32 can be separated from the flat conductor 4 (such as Figure 10 ). Among them, the positions of the protrusion 332 and the concave hole can be interchanged. Preferably, a avoidance groove is opened on the lock body 33 corresponding to each contact arm 11. The avoidance groove is used to accommodate the contact arm 11 when the lock 3 presses down to lock the flat conductor 4, and can also play an isolation and shielding effect. This can also reduce the size of the metal terminal 1, and can achieve good elasticity of the contact arm 11, and further achieve good electrical contact. Preferably, as Figure 8 、 9 The lock body 33 has slots corresponding to the third connecting arms 113, and the shaft 331 passes through the slots continuously. After the third connecting arm 113 passes through the slots, it presses against the shaft 331, and the extended end of the third connecting arm 113 is further inserted into the crossbeam 12. The portion between the slots is a portion of the lock body 33, which also provides a certain degree of isolation and shielding.

[0061] The flat conductor connector of the present invention has grounding and shielding functions, wherein the grounding and shielding functions are achieved through a combination of methods. A grounding spring 5 is welded to the PCB 2 via a welding point. The grounding spring 5 has three contact springs 52 that contact the back of the flat conductor 4 to form a ground connection, thereby preventing the metal terminals 1 from interfering with each other and the external environment from interfering with the flat conductor connector. A locking spring 31 is embedded in the locking buckle 3. The locking spring 31 has three crimping springs 32. The crimping springs 32 contact the back of the flat conductor 4 to form a ground connection, thereby preventing the metal terminals 1 from interfering with each other and the external environment from interfering with the flat conductor connector.
