[0041] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 is a connector structure schematic diagram provided by an embodiment of the present application, Figure 2 is Figure 1 the exploded view. The connector 000 can include: a connector body 100, a terminal assembly 200 and a cover 300.

[0043] The connector body 100 in the connector 000 can have a receiving space C, and a first opening K1 and a first hollow groove M1 in communication with the receiving space C. Wherein, the first opening K1 is used for the end of the flexible circuit board 001 to be inserted into the receiving space C. That is, the end of the flexible circuit board 001 can be inserted into the receiving space C from the outside through the first opening K1.

[0044] The terminal assembly 200 in the connector 000 is located in the receiving space C, and the terminal assembly 200 is used for electrical connection with the part of the flexible circuit board 001 inserted into the receiving space C.

[0045] In order to more clearly see the structure of the cover 300 in the connector 000, please refer to Figure 3 , Figure 3 is a cover structure schematic diagram provided by an embodiment of the present application. The cover 300 in the connector 000 can be rotationally connected with the connector body 100. Wherein, the side of the cover 300 facing the connector body 100 has a first clamping portion 301.

[0046] In the present application, after the cover plate 300 in the connector 000 is turned towards the connector body 100, the first clamping portion 301 can pass through the first hollow groove M1, so that the first clamping portion 301 can be clamped with the part of the flexible circuit board 001 inserted into the accommodation space C. For example, the first clamping portion 301 and the first hollow groove M1 are both two, and the two first clamping portions 301 are correspondingly distributed with the two first hollow grooves M1.

[0047] In this case, after the end of the flexible circuit board 001 is inserted into the accommodation space C through the first opening K1, the cover plate 300 in the connector 000 can be turned towards the connector body 100. When the cover plate 300 is turned, the first clamping portion 301 can pass through the first hollow groove M1 and be clamped with the part of the flexible circuit board 001 inserted into the accommodation space C, so as to fix the flexible circuit board 001 inside the connector 000.

[0048] In the embodiment of the present application, the end of the flexible circuit board 001 can be inserted into the accommodation space C through the first opening K1 and contact the terminal assembly 200 located in the accommodation space C and form an electrical connection to realize signal transmission. However, in order to adapt to the tight space layout inside the electronic device, the flexible circuit board 001 usually needs to be bent in some directions, and such bending will generate a certain stress on the flexible circuit board 001, which can easily cause the connection between the flexible circuit board 001 and the connector 000 to loosen after long-term use or after being bent for many times.

[0049] And by arranging the first clamping portion 301 on the side of the cover plate 300 in the connector 000 facing the connector body 100, and arranging the first hollow groove M1 on the connector body 100 for the first clamping portion 301 to pass through, after the cover plate 300 is turned towards the connector body 100, the first clamping portion 301 on the cover plate 300 can pass through the first hollow groove M1, and then the first clamping portion 301 can be clamped with the end of the flexible circuit board 001 inserted into the accommodation space C through the first opening K1, so as to ensure that the end of the flexible circuit board 001 can be firmly fixed in the accommodation space C. Therefore, even if the flexible circuit board 001 is bent for many times and generates stress causing the flexible circuit board 001 to separate from the connector 000, after the cover plate 300 is closed with the connector body 100, the first clamping portion 301 is clamped with the end of the flexible circuit board 001, so that the flexible circuit board 001 will not loosen the connection with the connector 000, and then the reliability of the connection between the flexible circuit board 001 and the connector 000 is high.

[0050] In summary, the application provides a connector, comprising a connector body, a terminal assembly and a cover plate. Since the cover plate in the connector is provided with a first clamping portion on the side facing the connector body, and the connector body is provided with a first hollow slot for the first clamping portion to pass through, after the cover plate is turned towards the connector body, the first clamping portion on the cover plate can pass through the first hollow slot, and then the first clamping portion can be clamped with the end portion of the flexible circuit board inserted into the accommodation space through the first opening, so as to ensure that the end portion of the flexible circuit board can be firmly fixed in the accommodation space. Therefore, even if the flexible circuit board is bent multiple times and generates stress causing the flexible circuit board to separate from the connector, the cover plate can be closed with the connector body after the cover plate is clamped with the end portion of the flexible circuit board, so that the flexible circuit board will not be loose with the connector, and the reliability of the connection between the flexible circuit board and the connector is high.

[0051] In the embodiments of the application, please refer to Figure 4 , Figure 4 is another structure diagram of a cover plate provided by the embodiments of the application. The cover plate 300 in the connector 000 can include a cover plate body 302 and a first clamping portion 301.

[0052] The cover plate body 302 in the cover plate 300 can be rotationally connected with the connector body 100, and the cover plate body 302 has a second opening K2.

[0053] Among them, the first clamping portion 301 in the cover plate 300 is located on the side of the cover plate body 302 facing the connector body 100, and the first clamping portion 301 is connected with the cover plate body 302 at the second opening K2. For example, the first clamping portion 301 and the second opening K2 are both two, and the two first clamping portions 301 are respectively connected with the cover plate body 302 at the two second openings K2.

[0054] In this case, through the rotational connection of the cover plate body 302 and the connector body 100, the rotation operation of the cover plate 300 is more convenient, so that the operator can easily open or close the cover plate 300.

[0055] For example, the first clamping portion 301 in the cover plate 300 and the cover plate body 302 can be an integral molding structure.

[0056] In this way, not only can the connection between the first clamping portion 301 and the cover plate body 302 be more firm, reducing the risk of separation or fracture of the first clamping portion 301 and the cover plate body 302 due to long-term use or vibration, but also the integral molding design can reduce the steps in the assembly process, making the manufacturing process simpler, thereby reducing production costs.

[0057] In the embodiment of the present application, the cover plate body 302 in the cover plate 300 can be a plate-shaped structure made of a metal material, and the first clamping portion 301 in the cover plate 300 can be a sheet-shaped structure made of a metal material.

[0058] In the plate-shaped structure, the plate surface is perpendicular to the plate surface of the sheet-shaped structure, and the area of the plate surface of the sheet-shaped structure is less than or equal to the opening area of the second opening K2 in the cover plate body 302.

[0059] For example, the second opening K2 can be cut out on the cover plate body 302, and then part of the second opening K2 can be bent to form the first clamping portion 301.

[0060] In this case, the metal material can ensure that the cover plate body 302 and the first clamping portion 301 have high mechanical strength and can withstand large stress, thereby improving the durability of the connector 000. In addition, the cover plate body 302 made of a metal material can also serve as an effective electromagnetic shielding layer to reduce the influence of external electromagnetic interference on the terminal assembly 200 in the connector 000, thereby ensuring that the quality of high-frequency signal transmission is high.

[0061] In the embodiment of the present application, please refer to Figure 5 and Figure 6 , Figure 5 is another schematic diagram of a connector structure provided in the embodiment of the present application, Figure 6 is Figure 5 is a partial exploded view. The cover plate 300 in the connector 000 can further include a bent portion 303, and the bent portion 303 is connected to the side of the cover plate body 302 away from the first opening K1.

[0062] In the connector 000, after the cover plate 300 is buckled to the connector body 100, the bent portion 303 can cover the side of the connector body 100 away from the first opening K1.

[0063] In the present application, part of the terminal assembly 200 in the connector 000 is located on the side of the connector body 100 away from the first opening K1, and in this case, by covering the side of the connector body 100 away from the first opening K1 with the bent portion 303, the electromagnetic shielding capability of the connector 000 can be further enhanced, effectively reducing electromagnetic interference, thereby avoiding leakage and loss during high-frequency signal transmission.

[0064] In the embodiment of the present application, please refer to Figure 4 and Figure 7 , Figure 7is a structural schematic diagram of a connector body 100 provided by an embodiment of the present application. The cover plate 300 in the connector 000 can further include a second clamping portion 304, and the second clamping portion 304 is located on a side of the cover plate body 302 facing the bending portion 303. The connector body 100 has a third clamping portion 101 corresponding to the second clamping portion 304.

[0065] Wherein, after the cover plate 300 is buckled to the connector body 100, the second clamping portion 304 is clamped with the third clamping portion 101. For example, the second clamping portion 304 and the third clamping portion 101 are both two, and the two second clamping portions 304 are clamped with the two third clamping portions 101. The bending portion 303 is located between the two second clamping portions 304. In this way, through the clamping of the second clamping portion 304 and the third clamping portion 101, the connection stability between the cover plate 300 and the connector body 100 in the connector 000 can be enhanced, so as to ensure that the cover plate 300 will not be easily loosened or detached in the buckled state.

[0066] In the embodiment of the present application, as shown in Figure 4 and Figure 7 The cover plate 300 in the connector 000 can further include a rotating member 305 connected with the cover plate body 302.

[0067] The connector body 100 in the connector 000 has a receiving groove P, and a rotating shaft 102 fixed inside the receiving groove P, and the rotating member 305 is rotationally connected with the rotating shaft 102 in the receiving groove P. For example, the rotating member 305 and the rotating shaft 102 are both two, and the two rotating members 305 are connected with the two rotating shafts 102.

[0068] In this case, through the precise cooperation of the rotating member 305 and the rotating shaft 102, it can be ensured that the operation of the cover plate 300 is more smooth, and the convenience of the operator when opening or closing the cover plate 300 is improved.

[0069] In summary, the application provides a connector, comprising a connector body, a terminal assembly and a cover plate.
