Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and more particularly to a flexible connector. Background Technology

[0002] Flexible strip connectors are a common type of small electrical connector used in consumer electronics products such as computers and mobile phones. They are used to establish an electrical connection between a flexible strip and a circuit board. The flexible strip, also known as an FPC / FFC flexible strip, can also be called a flexible circuit board or flexible wire strip. It is used to insert into the flexible strip connector. To improve the retention force after insertion and ensure the stability of the electrical connection, existing flexible strip connectors usually include a flip cover. This flip cover is used to press the flexible strip firmly, making it difficult for it to detach from the connector. However, existing flexible strip connectors generally lack grounding functionality and have weak shielding capabilities against external interference signals, failing to meet the requirements of certain application scenarios. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a flexible connector to improve the problem that the existing technology cannot achieve good grounding and shielding functions.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a flexible connector, comprising an insulating body, a row of signal terminals and a row of ground terminals housed in the insulating body and distributed front to back, a flip cover assembled on the insulating body, and a pair of fixing members fixed to both ends of the insulating body. The flexible connector further comprises a shielding cover covering the insulating body and a metal backing plate embedded in the flip cover. The shielding cover covers the periphery of the ground terminals. A pair of U-shaped latching arms are provided at both ends of the metal backing plate. The latching arms protrude from the flip cover and engage with the fixing members.

[0005] Furthermore, the insulating body includes a top wall, a bottom wall and a pair of side walls. At least one positioning hole is provided on the top wall, and the positioning hole extends from top to bottom into the interior of the insulating body. The shielding cover is provided with at least one retaining piece inserted downward into the positioning hole.

[0006] Furthermore, the shielding cover has an elongated upper cover, a pair of fixing flaps extending downward from both longitudinal ends of the upper cover, and a rear cover extending downward from the rear edge of the upper cover. The retaining piece is integrally formed on the upper cover.

[0007] Furthermore, a slot is provided on the side wall, the slot extends from top to bottom into the interior of the side wall and penetrates the insulating body downwards, the fixing flap is inserted downwards into the slot and protrudes downwards from the insulating body to be soldered and fixed to a circuit board.

[0008] Furthermore, the insulating body is provided with a pair of rearwardly protruding convex walls, which are distributed at both ends of the insulating body in the longitudinal direction and are located behind the side wall. A groove is also formed on the convex wall. Both ends of the rear cover are provided with ends that are engaged in the groove.

[0009] Furthermore, the flip cover has a longitudinally elongated main cover plate and mounting portions that protrude outward from both longitudinal ends of the main cover plate. A pair of through holes are also formed on the main cover plate, and the through holes pass through the main cover plate.

[0010] Furthermore, the metal liner is embedded in the flip cover by injection molding, and the metal liner has a longitudinally elongated base plate, and the pair of U-shaped buckle arms are bent and extended from the longitudinal ends of the base plate.

[0011] Furthermore, the substrate is sheet-shaped, with several through holes and at least one downwardly bent and extended spring arm on its surface. The spring arm extends downwardly and passes through the through hole to be pressed onto a flexible strip.

[0012] Compared with the prior art, this utility model achieves better signal shielding by setting a shielding cover around the grounding terminal and a metal liner inside the flip cover, which also increases the strength of the flip cover. At the same time, the snap-fit ​​between the metal liner and the fastener can effectively improve the bonding force between the flip cover and the insulating body, ensuring that the flexible busbar will not easily loosen.

[0018] Please see Figures 1 to 5As shown, this utility model provides a flexible circuit board connector 100, including: an elongated insulating body 10, a plurality of terminals 20 housed within the insulating body 10, a pair of fixing members 30 fixed at both ends of the insulating body 10, a flip cover 40 assembled on the insulating body 10, a metal backing plate 50 embedded within the flip cover 40, and a shielding cover 60 covering the insulating body 10. The insulating body 10 is used to support the terminals 20, fixing members 30, and shielding cover 60, while the fixing members 30 are used to weld and fix the insulating body 10 to a circuit board (not shown), and the terminals 20 are used to crimp and contact a flexible circuit board (such as a flexible printed circuit board FPC, FFC, etc.).

[0019] like Figure 2 and Figure 3 As shown, the insulating body 10 includes a top wall 11, a bottom wall 12, and a pair of side walls 13. The top wall 11 and the bottom wall 12 are longitudinally elongated, with their longitudinal ends integrally connected to the pair of side walls 13. The top wall 11 is located behind and higher than the bottom wall 12, thus protruding from the bottom wall 12. The upper surface of the top wall 11 is flush with the upper surface of the pair of side walls 13. The bottom wall 12 has a plurality of equally spaced channels 121 for accommodating the plurality of terminals 20. Preferably, the top wall 11 has at least one positioning hole 111 extending from top to bottom into the interior of the insulating body 10 for holding and fixing the shielding cover 60. Figure 5 As shown. The pair of sidewalls 13 extend forward integrally from both longitudinal ends of the top wall 11, and the inner side of the sidewall 13 is provided with a slot 17 for accommodating the fixing member 30. Preferably, each sidewall 13 has a slot 131, which extends from top to bottom into the interior of the sidewall 13 and penetrates downward through the insulating body 10, so that the shielding cover 60 can pass through to achieve soldering and fixing with the circuit board. Preferably, the slots 131 are located at both longitudinal ends of the top wall 11, so that the shielding cover 60 is combined and fixed to the top wall 11 and the sidewall 13 by means of the slots 131 and the positioning holes 111, so as to achieve reliable connection and fixing with the insulating body 10. The bottom wall 12 is located between the pair of sidewalls 13, and the bottom wall 12 has a plurality of terminal slots 121 for accommodating the terminals 20. The bottom wall 12, the top wall 11 and the pair of sidewalls 13 form an accommodating space for accommodating the flexible strip. Preferably, in order to further fix the shielding cover 60, the insulating body 10 is also provided with a pair of rearwardly protruding convex walls 14. The pair of convex walls 14 are distributed at both ends of the longitudinal direction of the insulating body 10, and the convex walls 14 are located behind the side wall 13. The convex walls 14 are integrally connected with the side wall 13 and the top wall 11. A slot 141 is also formed on the convex wall 14 for holding and fixing the shielding cover 60, so that the shielding cover 60 is better combined and fixed with the insulating body 10.

[0020] like Figure 3 and Figure 5 As shown, the terminal 20 includes a row of signal terminals 21 and a row of ground terminals 22 distributed front to back. The signal terminals 21 are inserted into the groove 121 of the bottom wall 12 from front to back, while the ground terminals 22 are inserted into the insulating body 10 from back to front. The signal terminals 21 and ground terminals 22 are distributed front to back. Specifically, the signal terminals 21 are fixed to the bottom wall 12 and have contact arms 23 that protrude upward from the bottom wall 12 for electrical contact with the flexible busbar. The ground terminals 22 have a top arm 24 that extends horizontally forward to above the signal terminals 21 and a welding arm 25 that extends horizontally backward out of the insulating body 10. The top arm 24 is used to pivotally engage with the flip cover 40, and the welding arm 25 is used to weld to the circuit board.

[0021] like Figure 3 As shown, the flip cover 40 has a longitudinally elongated main cover plate 41 and mounting portions 42 protruding outward from both longitudinal ends of the main cover plate 41. The inner edge of the main cover plate 41 forms several slots 43 and a pivot shaft (not shown) located within the slots 43. The slots 43 are used to accommodate the top arm 24 of the grounding terminal 22, and the pivot shaft pivotally engages with the top arm 24. Preferably, the main cover plate 41 also has a pair of through holes 45 that penetrate the main cover plate 41.

[0022] The metal backing plate 50 is embedded in the flip cover 40 by injection molding. The metal backing plate 50 has a longitudinally elongated base plate 51 and a pair of snap-fit ​​arms 52 extending from both longitudinal ends of the base plate 51. The base plate 51 is sheet-shaped and has several through holes 53 and at least one downwardly bent and extending spring arm 54 on its surface. The through holes 53 are used to increase the bonding force with the flip cover 40. The spring arm 54 extends downward at an angle and passes through the through hole 45 to press against the soft board under the flip cover 40, providing grounding and clamping functions. The snap-fit ​​arms 52 are U-shaped and protrude from both longitudinal ends of the main cover plate 41 for snap-fit ​​fixing with the fastener 30.

[0023] The fastener 30 has a long strip-shaped insert arm 31 extending horizontally backward and an inverted U-shaped pressing piece 32 located at the front end of the insert arm 31 and folded inward. The insert arm 31 is inserted into the side wall 13 of the insulating body 10 and fixed in the slot 17. The pressing piece 32 is used to abut against the buckle arm 52 of the metal liner 50, thereby achieving interference fixation with the metal liner 50, so that the flip cover 40 can be firmly and reliably fixed on the insulating body 10 after it is flipped down and closed, so that the soft board is not easy to loosen after being pressed.

[0024] The shielding cover 60 is disposed on the surface of the top wall 11 of the insulating body 10, and is used to cover the grounding terminal 22, such as Figure 3 , Figure 5 As shown, the shielding cover 60 is integrally stamped from metal and includes an elongated upper cover 61, a pair of fixing tabs 62 extending downward from both longitudinal ends of the upper cover 61, and a rear cover 63 extending downward from the rear edge of the upper cover 61. The upper cover 61 covers the surface of the top wall 11. The fixing tabs 62 are inserted downward into the slots 131 to fix them to the insulating body 10. The rear cover 63 covers the rear side of the insulating body 10. The upper cover 61 and the rear cover 63 respectively cover the outer side of the grounding terminal 22, effectively shielding interference signals. Preferably, the upper cover 61 has at least one opening 64 and at least one downwardly bent retaining tab 65 located within the opening 64. The retaining tab 65 is inserted downward into the positioning hole 111 of the top wall 11 of the insulating body 10, thereby strengthening the bonding force between the shielding cover 60 and the insulating body 10. Preferably, the rear cover 63 has end portions 66 at both ends that engage with the slots 141.

[0025] In summary, this utility model achieves better signal shielding by setting a shielding cover 60 around the grounding terminal 22 and a metal liner 50 inside the flip cover 40, which also increases the strength of the flip cover 40. At the same time, the snap-fit ​​between the metal liner 50 and the fastener 30 can effectively improve the bonding force between the flip cover 40 and the insulating body 10, ensuring that the flexible board will not easily loosen.
