Description

Technical Field

[0001] The present application relates to the technical field of FPC (flexible printed circuit), and in particular to an FPC connector. Background Art

[0002] With the continuous development of electronic devices, flexible printed circuits (FPC) are widely used due to their thinness and bendability. As the key connecting component between the FPC flexible circuit and the motherboard, the stability and ease of use of the FPC connector have an important impact on the overall performance of electronic devices.

[0003] At present, although the FPC connectors on the market can realize basic connection functions, they still need to be improved in terms of ease of use and connection stability, especially in electronic equipment that needs frequent disassembly or maintenance.

[0004] Traditional FPC connectors usually consist of two parts: a connector body and a gland. When connecting, the end of the FPC cable needs to be inserted into the slot of the connector body and then fixed with the gland. However, this connection method is prone to loosening the connection between the gland and the connector body, or causing the gland to deform or even break during frequent disassembly and assembly, which affects the service life of the FPC connector.

[0005] Therefore, there is an urgent need for an FPC connector with reliable connection effect and long service life, so that the FPC connector can play a role in FPC applications for a longer period of time. Summary of the invention

[0011] The gland includes a cover body and a rotating shaft, and both ends of the rotating shaft have mounting structures respectively; the connector body has a mounting space for the mounting structure to enter, and the second extension portion has a notch adapted to the rotating shaft; after the gland and the plurality of conductive contacts are mounted on the connector body, the rotating shaft is located in the corresponding notch, the mounting structure is located in the mounting space, and the gland can rotate relative to the connector body;

[0012] A plurality of positioning grooves are provided on one side of the connector body close to the snap-in groove, and a plurality of positioning portions are provided on the positioning member that are interference fit with the positioning grooves; after the positioning member and the plurality of the conductive contacts are installed on the connector body, the positioning member is located on the side of the conductive contacts facing away from the connector body and abuts against the conductive contacts.

[0013] By adopting the above technical scheme, it is convenient for users to disassemble and assemble the FPC connector, thereby facilitating the replacement of parts and extending the service life of the FPC connector; it is possible to reduce the connection dependence of the gland rotation on the connector body, so that the gland can be rotated both through the connection relationship between the gland and the connector body and through the matching relationship between the gland and the multiple conductive contacts, so as to reduce the probability of concentrated damage to the gland during the rotation process. On the premise of ensuring its connection effect, the service life of the gland can be effectively improved, thereby effectively improving the service life of the connector, so that the FPC connector can function more stably for a long time.

[0023] By adopting the above technical scheme, after the pressure cover is controlled to rotate and open, the expanded deformation part can drive the pressure cover to an open state, which is convenient for users to perform related operations; after the pressure cover is controlled to rotate and close, the deformed and expanded deformation part can drive the pressure cover to maintain a closed state, and the effect of the force of the deformed and contracted deformation force on the rotation of the pressure cover can be ignored, thereby further improving the position stability of the pressure cover after closing.

[0072] Reference Figure 5 and Figure 8 When the mating portion 441 enters the mating groove 51 and is mated with the mating groove 51, the rotation of the gland 4 relative to the connector body 1 can be controlled to drive the rotating member 5 to rotate relative to the connector body 1. The rotation of the rotating member 5 relative to the connector body 1 is limited. When the gland 4 is in an open state, the rotating member 5 rotates to an extreme position relative to the connector body 1, and the mating groove 51 is connected to the slide groove 181; when the gland 4 is in a closed state, the rotating member 5 rotates to another extreme position relative to the connector body 1, and the opening of the mating groove 51 for the mating portion 441 to enter and exit is closed by the groove wall of the first clearance groove 182.

[0073] Reference Figure 7 and Fig. 9 The deformable member 6 and the sliding member 7 are both installed in the second paving groove 183 and are both located at the end of the second paving groove 183 away from the opening thereof. The mounting structure 44 further includes a contact portion 442, which is located at a side of the adjacent matching portion 441 close to the rotating shaft 42. When the matching portion 441 slides with the slide groove 181 and enters the slide groove 181, the contact portion 442 enters the second paving groove 183 accordingly. In the process of the contact portion 442 rotating with the pressure cover 4, the contact portion 442 and the groove wall of the second paving groove 183 are kept at a distance.

[0074] When the matching portion 441 is matched with the matching groove 51 , the contact portion 442 is located in the second paving groove 183 close to the adjacent deformable member 6 and the sliding member 7 , and is located on a side of the sliding member 7 close to the opening of the second paving groove 183 .

[0075] Both ends of the deformable member 6 have a deformable portion 61, one deformable portion 61 is located at the bottom of the second give way groove 183 away from the end of its own opening, and the other deformable portion 61 is located at the top of the second give way groove 183 and close to the end of the second give way groove 183 away from the end of its own opening. Both deformable portions 61 can expand and contract, and the expansion or contraction of one deformable portion 61 will drive the other deformable portion 61 to contract or expand. In this embodiment, it is preferred that the interior of the deformable member 6 has a cavity, the spaces inside the two deformable portions 61 are connected through the cavity, and the two deformable portions 61 are made of rubber material, so that the deformation of the deformable portion 61 can drive the deformation of the other deformable portion 61; and it is preferred that under the normal state of the deformable member 6, the deformable portion 61 located at the bottom of the end of the second give way groove 183 away from the end of its own opening is in an expanded state, and the deformable portion 61 located at the top of the second give way groove 183 and close to the end of the second give way groove 183 away from the end of its own opening is in a contracted state.

[0078] When the sliding member 7 slides to the limit position in the direction close to the opening of the second clearance groove 183, the sliding member 7 just contacts the deformed portion 61 at the bottom of the end of the second clearance groove 183 away from its own opening; when the sliding member 7 slides to the limit position in the direction away from the opening of the second clearance groove 183, the sliding member 7 will squeeze the deformed portion 61 at the bottom of the end of the second clearance groove 183 away from its own opening, causing it to shrink to the minimum, while driving the other deformed portion 61 to expand to the maximum. In this embodiment, it is preferred that the side of the sliding member 7 that contacts the deformed portion 61 is a plane, and the plane is perpendicular to the sliding direction of the sliding member 7; and it is preferred that when the sliding member 7 is not subjected to external force, the deformed portion 61 at the bottom of the end of the second clearance groove 183 away from its own opening can drive it to slide to the limit position in the direction close to the opening of the second clearance groove 183 and maintain it.

In this embodiment, it is preferred that both ends of the contact portion 442 in the length direction have arc surfaces, and the axis of the arc surface coincides with the axis of the rotating shaft 42.

[0080] Reference Figure 5 and Figure 7 , the length direction of the contact portion 442 is parallel to the width direction of the cover body 41. When the gland 4 is in the open state, the length direction of the contact portion 442 is parallel to the height direction of the connector body 1, and the bottom of the contact portion 442 is in contact with the sliding member 7, and there is a gap between the top of the contact portion 442 and the deformed portion 61 at the top of the deformed member 6. At this time, it is necessary to overcome the deformation force of the deformed portion 61 in contact with the sliding member 7 in order to control the gland 4 to rotate relative to the connector body 1 so that the gland 4 can rotate and cover, so that the gland 4 can remain in the open state according to the use requirements.

[0081] Reference Figure 5 and Fig. 9 When the gland 4 is rotated to the closed state, the length direction of the contact portion 442 is parallel to the width direction of the connector body 1. During this process, one end of the contact portion 442 will push the sliding member 7 to slide and drive the adjacent deformation portion 61 to gradually shrink to the minimum, and the other deformation portion 61 will gradually expand to the maximum and then contact and resist the other end of the contact portion 442 above the contact portion 442, and exert a downward force on it. At this time, if the gland 4 needs to be rotated to open it, it is also necessary to overcome the deformation resistance of the larger deformation member 6, so that the gland 4 can remain in the closed state according to the use requirements.

[0082] The implementation principle of an FPC connector in the embodiment of the present application is:

[0083] When in use, the pressure cover 4 is first controlled to rotate and open. At this time, the force exerted by the deformable member 6 on the contact portion 442 through the sliding member 7 can drive the pressure cover 4 to remain in an open state, which is convenient for the user to perform subsequent operations; then the end of the FPC cable is inserted into the connecting groove 11, and then the pressure cover 4 is controlled to rotate and cover. At this time, the deformable member 6 can directly exert forces in different directions on the two ends of the contact portion 442 through the sliding member 7, so that the pressure cover 4 can remain in a closed state, thereby improving the effect of the pressure cover 4 on reinforcing the connection of the FPC cable end, thereby making the use of the FPC connector more reliable;

[0084] When there are parts of the FPC connector that need to be replaced, the positioning member 3, the conductive contact piece 2 and the pressure cover 4 are removed in sequence, and then the parts to be replaced can be replaced, which is convenient for disassembly and assembly.

[0085] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
