[0002] The flexible jack connector is a small electrical connector that is very commonly used in consumer electronic products such as computers and mobile phones. It is used to establish an electrical connection between the flexible jack and the circuit board. The flexible jack is an FPC / FFC flexible jack, which can also be called a flexible circuit board or a flexible cable jack. It is used to be plugged into the flexible jack connector. In order to improve the retention force of the flexible jack after insertion and ensure the stability of the electrical connection, existing flexible jack connectors also usually include a flip cover. The flip cover is used to press the flexible jack to prevent it from being easily disconnected from the flexible jack connector. However, the signal terminal and ground terminal of existing flexible jack connectors are integrated, which cannot provide good signal shielding. Therefore, the grounding function is usually lacking, and the shielding ability against external interference signals is also weak, which cannot meet the usage requirements in certain application scenarios.

The upper surface of the top wall 11 is flush with the upper surfaces of the pair of side walls 13, and a plurality of upper grooves 14 are opened in the top wall 11. Preferably, a plurality of notches 111 are formed on the rear edge of the top wall 11, and the plurality of notches 111 are arranged one-to-one with the plurality of notches 43 on the flip cover 40. After the flip cover 40 is flipped over, it rests on the rear edge of the top wall 11. The bottom wall 12 is provided with a plurality of lower grooves 15 arranged at equal intervals, and the lower grooves 15 and the upper grooves 14 on the top wall 11 together constitute a receiving groove for accommodating the plurality of terminals 20. Preferably, a T-shaped partition 16 is provided between two adjacent lower grooves 15 of the bottom wall 12 (see FIG. Figure 3), used to clamp and limit the side edge of the terminal 20. Preferably, one end of the lower groove 15 passes through the bottom wall 12 downward, and a hole 18 is formed on the bottom surface of the bottom wall 12. Preferably, a plug-in slot 19 for inserting a flexible cable is formed between the bottom wall 12 and the top wall 11, and a pair of upwardly protruding limiting protrusions 121 are also provided at both longitudinal ends of the bottom wall 12. The limiting protrusions 121 are located on the inner side of the side wall 13 and protrude from the upper surface 12A of the bottom wall 12. They protrude into the plug-in slot 122 to clamp and limit the flexible cable. A card slot 17 for accommodating the fixing member 30 is provided on the inner side of the side wall 13, and the card slot 17 extends from front to back. Preferably, the side wall 13 is a double-layer structure, which includes an inner wall 131 and an outer wall 132 connected in one piece, the slot 17 is formed between the inner wall 131 and the outer wall 132, and the outer wall 132 is smaller in the front-to-back direction than the inner wall 131, and the outer wall 132 is also smaller in the vertical direction than the inner wall 131. Figure 3 In a preferred embodiment of the present invention, the insulating body 10 is further provided with a rear wall 19 , on which are formed a plurality of fixing protrusions 191 arranged at equal intervals for fixing the grounding terminal 22 of the terminal 20 , and a reserved groove 192 is formed between two adjacent fixing protrusions 191 .

[0022] like Figure 3 and Figure 5As shown, the terminal 20 includes a row of signal terminals 21 and a row of ground terminals 22 distributed front to back, wherein the signal terminal 21 is long and strip-shaped and is inserted into the lower groove 15 of the bottom wall 12 from front to back, and the ground terminal 22 is inserted into the upper groove 14 in the top wall 11 from back to front. The signal terminal 21 and the ground terminal 22 are distributed front to back. Specifically, the signal terminal 21 is fixed on the bottom wall 12, and is provided with a horizontally extending long strip base 23, a contact arm 24 extending obliquely upward from the rear end of the base 23, and a mounting arm 25 extending forward from the front end of the base 23 out of the bottom wall 12. The contact arm 24 protrudes upward from the upper surface 12A of the bottom wall 12 to be crimped into contact with the soft row, and the extension length of the contact arm 24 in the front-to-back direction is greater than the length of the mounting arm 25 and the base 23.

It should be noted that the stop arm 26 and the hole 18 are arranged in correspondence with each other above and below, and the hole 18 is located directly below the stop arm 26. When the contact arm 24 is crimped into contact with the soft row and elastically displaced downward, the stop arm 26 can be displaced downward into the hole 18, that is, the setting of the hole 18 on the bottom wall 12 provides more downward displacement space for the stop arm 26, thereby making the deformation range of the contact arm 24 larger, avoiding the risk of the stop arm 26 being directly hard against the bottom wall 12 and easily being crushed and deformed. The grounding terminal 22 includes a vertically arranged main arm 27, a top arm 28 integrally connected to the top of the main arm 27 and extending horizontally, and a base 29 integrally connected to the rear side of the main arm 27. The main arm 27 is used to support the top arm 28 and connect the top arm 28 and the base 29. The top arm 28 and the main arm 27 together form a T-shaped structure. The base 29 is fixed to the rear wall 19 of the insulating body 10 and protrudes backward from the rear wall 19 (see FIG.

Preferably, the base 29 is in a thin sheet shape, and its bottom is welded to the circuit board.

[0023] The flip cover 40 extends longitudinally, with its inner edge 40A configured to engage with the grounding terminal 22 and its outer edge 40B configured for flipping. The inner edge 40A is formed with a plurality of notches 43 and pivot shafts 44 positioned within the notches 43. The notches 43 are configured to accommodate the top arm 28 of the grounding terminal 22. The pivot shaft 44 is disposed on the base 29 of the grounding terminal 22 and below the top arm 28. Preferably, the notches 43 correspond one-to-one with the recesses 111 on the top wall 11, and the number of notches 43 is twice the number of the top arms 28. The pivot shaft 44 is elliptical and has a protrusion 45 on its surface, enabling the pivot shaft 44 to act on the rear end 28B of the top arm 28 during rotation, thereby enabling the front end 28A of the top arm 28 to tighten or loosen the flexible strip.

[0024] The fixing member 30 is an M-shaped metal sheet, which is provided with a horizontally extending connecting arm 31 and at least a pair of fixing legs 32 extending downward from the lower edge of the connecting arm 31. Figure 4 As shown, the fixing member 30 is retained within the slot 17 of the side wall 13 and positioned between the inner wall 131 and outer wall 132 of the side wall 13. Preferably, the connecting arm 31 protrudes upward from the outer wall 132 of the side wall 13. The pair of fixing legs 32 extend downward through the insulating body 10 to be soldered to the circuit board, and the pair of fixing legs 32 are arranged in a front-to-back relationship. Preferably, the fixing member 30 further includes an inner pin 33 positioned between the pair of fixing legs 32. The inner pin 33 is sheet-shaped and wider than the fixing legs 32. Preferably, the bottom surface of the side wall 13 is formed with openings (not shown) corresponding to the pair of fixing legs 32 and the inner pin 33.

[0025] In summary, the present invention optimizes the structure and layout of the terminal 20 and utilizes the independently distributed ground terminals 22 and signal terminals 21 in the front and back to achieve a better grounding shielding effect while ensuring good high-speed signal transmission quality.
