Description

Technical Field

[0001] The utility model relates to the field of electrical connectors, and particularly relates to an electrical connector which is convenient for stable connection. Background Art

[0002] The FPC electrical connector is an indispensable and important part of electronic devices, which is responsible for realizing the electrical connection and signal transmission between circuits, between circuits and devices, and between devices. Among them, the grounding spring piece plays a crucial role in the FPC electrical connector. It can not only provide an effective grounding path to protect the circuit from electromagnetic interference, but also directly affect the connection stability and reliability between the FPC electrical connector and the circuit board.

[0003] The existing FPC electrical connectors generally realize the guiding and auxiliary pressing functions for the circuit board through the elastic arms on the grounding terminals. However, due to the lack of support for the elastic arms, under the influence of long-term use or repeated plugging and unplugging, problems such as fatigue failure and elastic attenuation of the elastic arms are likely to occur. As a result, when inserting into the circuit board, the elastic arms no longer rebound downward, losing the guiding function and being unable to achieve the effect of auxiliary pressing. Thereby, it affects the connection stability and service life of the electrical connector and the circuit board. Therefore, the utility model proposes an electrical connector which is convenient for stable connection. Summary of the Invention

Detailed Embodiments

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0024] In this embodiment, refer to Figures 1 - 5 The invention specifically implements an electrical connector that facilitates stable connection, including a base 1, a rotatable pressure plate 2 mounted on the base 1, a conductive terminal 3 for connecting and cooperating with a circuit board, and a grounding terminal 4 for compressing and preventing electromagnetic interference. The grounding terminal 4 includes a fixed plate 5, a grounding plate 6, a bending arm 7, and an elastic arm 8. The bending arm 7 extends outward along one side of the fixed plate 5. The elastic arm 8 includes a contact portion 10 and a downwardly inclined guide portion 9. The guide portion 9 and the contact portion 10 are sequentially arranged on one side of the bending arm 7 along a first direction, leaving a certain gap on the fixed plate 5. The end of the contact portion 10 away from the bending arm 7 is provided with an upwardly inclined contact block 11, and the pressure plate 2 is provided with a fixed block 12 that cooperates with the contact block 11. The downwardly inclined design of the guide portion 9 allows the circuit board to be accurately inserted into the electrical connector and pre-compressed when inserted. Then, through the cooperation between the contact block 11 and the fixed block 12 on the transfer plate 2, the elastic arm 8 provides a downward supporting force for the pressing action of the elastic arm 8 after the transfer plate 3 is closed, preventing it from deforming downward, thereby reducing fatigue failure, elastic weakening and other problems caused during use, improving the durability and stability of the elastic arm 8, and thus ensuring a stable connection between the circuit board and the electrical connector.

[0025] Furthermore, one end of the contact portion 10 is tilted upward. The upward tilted contact portion 10 cooperates with the downward tilted guide portion 9, so that when the contact block 11 and the fixing block 12 are engaged, a more stable support effect is achieved, so that the elastic arm 8 is firmly attached to the circuit board, thereby enhancing the overall stability of the electrical connector.

[0026] Furthermore, the elastic arm 8 also includes a curved elastic portion 13, and the two ends of the guide portion 9 are respectively connected to the bending arm 7 and the contact portion 10 through the curved elastic portion 13. When the circuit board is inserted or removed, the curved elastic portion 13 can adapt to the changes in movement, maintain good contact between the contact portion 10 and the circuit board, and avoid wear or damage caused by hard contact. In addition, the presence of the curved elastic portion 13 also significantly improves the durability and fatigue resistance of the entire structure. During the frequent insertion and removal of circuit boards, this design can effectively absorb and disperse stress, reduce direct impact on the bending arm 7, and thus extend the service life of the grounding terminal 4.

[0027] Furthermore, the curved elastic portion 13 is arc-shaped. This arc-shaped design reduces the contact area between the curved elastic portion 13 and the circuit board, allowing for a smoother transition when inserting or removing the circuit board. Furthermore, the arc-shaped design provides a more even distribution of elasticity, further enhancing the durability and fatigue resistance of the elastic arm 8.

[0028] Furthermore, both ends of the base 1 are provided with slots 14 for installing the fixing plate 5. The design of the slots 14 facilitates the quick installation and disassembly of the fixing plate 5 and the base 1, improving the maintainability of the product and the convenience of replacing parts. It ensures that during the operation of the electrical connector, the grounding terminal 4 will not loosen due to vibration or external force, thereby ensuring the overall stability and reliability of the electrical connector. The slots 14 and the fixing plate 5 are respectively provided with a limiting groove 15 and a limiting block 16 that cooperate with each other. Through the cooperation of the limiting groove 15 and the limiting block 16, the fixing plate 5 is accurately positioned and firmly locked in the slot 14 of the base 1. When the fixing plate 5 is inserted into the slot 14 of the base 1, the limiting block 16 engages with the limiting groove 15, so that the fixing plate 5 is firmly fixed in the slot 14. It effectively prevents the displacement or shaking of the fixing plate 5 during long-term use or under the action of external forces.

[0029] Furthermore, reinforcing ribs 17 are provided at the connection between the bending arm 7 and the fixing plate 5. The addition of these ribs significantly enhances the strength and rigidity of the connection between the bending arm 7 and the fixing plate 5, preventing deformation or breakage of the bending arm 7 due to the long-term pressure of the elastic arm 8. This design ensures the stability and durability of the entire grounding terminal 4 structure, maintaining excellent performance even in high-frequency usage scenarios.

[0030] Furthermore, the angle between contact block 11 and bent arm 7 is acute. This reduces the space occupied by contact block 11, making the entire electrical connector more compact. Furthermore, when pressed by fixing block 12, contact block 11 can more effectively transmit pressure to the contact point between elastic arm 8 and the circuit board, thereby enhancing the clamping effect on the circuit board and preventing signal interruption or interference caused by poor contact.

[0031] The beneficial effects of this utility model include: the downwardly inclined guide portion 9 guides the circuit board accurately into the electrical connector and assists in tightening it during insertion. Furthermore, the contact block 11 cooperates with the fixed block 12 on the transfer plate to provide support for the elastic arm 8 after the transfer plate 2 is closed, reducing fatigue failure and elasticity loss during use. This improves the durability and stability of the elastic arm 8, thereby ensuring a stable connection between the circuit board and the electrical connector.
