Description

Technical Field

[0001] The invention relates to the technical field of FPC connectors, and in particular to an upright FPC connector with insertion protection. Background Art

[0002] An upright FPC connector with insertion protection is mainly used to achieve stable and reliable electrical connection between FPC (flexible circuit board) and other electronic components. It is widely used in the internal circuit connection of various electronic devices such as mobile phones, tablets, laptops, etc. to ensure the accuracy and stability of signal transmission and avoid equipment failures caused by poor connection.

[0003] In practical applications, upright FPC connectors with insertion protection usually require the following technologies:

[0004] 1. High-precision conductive contact piece to ensure good electrical conduction with FFC (flexible flat cable); the conductive contact piece is made of high-quality conductive metal material and has been finely processed to have appropriate elasticity and surface roughness. It can reduce contact resistance when in close contact with FFC, ensure efficient signal transmission, and maintain stable contact performance during multiple plug-in and pull-out processes.

[0005] 2. Stable insulating shell material to prevent short circuit and leakage; the insulating shell is made of plastic material with high insulation performance, high temperature resistance and aging resistance, which can effectively isolate various conductive parts. Even in complex electromagnetic environment and high temperature environment, it can ensure the safety of the internal circuit of the connector and avoid equipment damage or safety accidents caused by short circuit or leakage.

[0006] 3. The clever wedge-shaped guide block and guide arm structure enable dynamic adjustment of the card slot space; the design of the wedge-shaped guide block and guide arm is one of the key innovations of this connector. The wedge-shaped guide block can accurately transfer force to the guide arm when the FFC is inserted, causing the guide arm to produce a suitable offset, thereby flexibly expanding the card slot space and facilitating the smooth insertion of the FFC. After the FFC is inserted into place, the guide arm can quickly reset by relying on its own elasticity or other reset mechanisms, so that its contact point fits closely to the corresponding position of the FFC, ensuring the stability and reliability of the connection, and effectively preventing the FFC from having poor contact due to looseness.

[0007] 4. Durable pressing plate material and reasonable installation structure ensure long-term stable operation; the pressing plate is made of strong and elastic material, which can withstand a certain operating force without deformation or damage during the FFC insertion process. Its installation structure is closely matched with the wedge-shaped guide block to ensure accurate and effective force transmission, and it can still maintain good performance after repeated use, and will not affect the overall function of the connector due to wear or looseness.

[0008] At present, in the field of circuit connection of electronic equipment, manufacturers have adopted various types of connectors to meet the connection requirements between FPC and other components. Some connectors are fixed with card-mounted slots, which require a large external force when inserting FFC, which can easily damage FFC and connector, and FFC is easy to loosen after insertion, affecting the stability of the connection. Some connectors have simple guiding structures, but they have poor adaptability when dealing with FFCs of different thicknesses and cannot guarantee good contact effects. Although some high-end connectors have excellent performance, they are complex in structure and high in cost, which is not conducive to large-scale popularization and application.

[0009] However, there is a problem with the above method, that is, the stability and adaptability of the connector in actual use are poor, especially when modern electronic devices are constantly miniaturized and lightweight, and the requirements for internal circuit connections are getting higher and higher. Existing connectors are difficult to meet the needs of efficient, stable and reliable connections. In response to this problem, the present application proposes a solution and designs an upright connector with a pressing plate installed on the FPC connector. During the FFC insertion process, the pressing plate cooperates with the wedge-shaped guide block to drive the guide arm to deflect, expand the card slot space to facilitate the insertion of the FFC, and after the insertion is in place, the guide arm resets and closely contacts the FFC, which effectively improves the stability of the product during use, can adapt to the insertion requirements of FFCs of different thicknesses, provides a better solution for the circuit connection of electronic equipment, and improves the overall performance and reliability of electronic equipment.

[0030] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in view of the problems existing in the prior art, the present invention provides an upright FPC connector with insertion protection, comprising an insulating body 1, an insulating cover 2, two card-jointing pieces 23 and a conductive terminal group 3, wherein the insulating body 1 is provided with a plurality of card-jointing cavities 11, the conductive terminal group 3 is plugged with the corresponding card-jointing cavities 11, the conductive terminal group 3 is inserted into the corresponding slot of the insulating body 1 for positioning and arrangement, the conductive terminal group 3 is a terminal with a guiding function, the conductive terminal group 3 comprises a plurality of conductive terminals 31, each conductive terminal 31 is provided with a card-jointing arm 32, each conductive terminal 31 is provided with an elastic arm cavity 1 33, an elastic arm cavity 2 34 and an elastic arm cavity 35. 4 and a card-mounting slot 35, each conductive terminal 31 is provided with an elastic arm 36, each elastic arm 36 is provided with a guide arm 37, and each guide arm 37 has a contact point on one side, and a plurality of sliding holes 12 are provided on the insulating body 1, and a same pressing plate 13 is slidably installed in each sliding hole 12, and a wedge-shaped guide block 14 is slidably installed on one side of each sliding hole 12, and two fixing rods 15 are fixedly installed on the insulating body 1, and springs 16 are fixedly sleeved on the two fixing rods 15, wherein the card-mounting slot 35 is used to insert the FFC, each wedge-shaped guide block 14 is fixedly connected to the pressing plate 13, and the pressing plate 13 is slidably installed on the two fixing rods 15. The pressing plate 13 is fixedly mounted on the upper ends of the two springs 16, and the pressing plate 13 is pressed downward. The pressing plate 13 is forced to squeeze the spring 16, and the spring 16 is deformed under the force. The deformation of the spring 16 releases the limit of the pressing plate 13, and the pressing plate 13 is forced to slide on the fixed rod 15. The sliding of the pressing plate 13 drives the wedge-shaped guide block 14 to move downward, and the wedge-shaped guide block 14 moves downward to contact the guide arm 37. The wedge-shaped guide block 14 moves to squeeze the guide arm 37. The guide arm 37 is forced to drive the elastic arm 36 to deflect, so that the space of the card slot 35 is expanded, and then the FFC is inserted into the card slot 35. After the pressing plate 13 is released, the spring 16 resets and drives the pressing plate 13 and the wedge-shaped guide block 14 to reset, and then the guide arm 37 resets.

The pressing plate 13 is forced to squeeze the spring 16, and the spring 16 is deformed under the force, and the limit of the pressing plate 13 is released. The pressing plate 13 slides on the fixed rod 15 and drives the wedge-shaped guide block 14 to move downward. The wedge-shaped guide block 14 moves and squeezes the guide arm 37. The guide arm 37 is forced to drive the elastic arm 36 to deviate, thereby expanding the space of the card slot 35. At this time, the FFC can be easily pulled out of the card slot 35. After releasing the pressing plate 13, the spring 16 resets and drives the pressing plate 13 and the wedge-shaped guide block 14 back to the initial position.

[0032] Preferably, the contact point of each guide arm 37 faces one side of the conductive terminal 31, and the contact point on the guide arm 37 is close to the corresponding position of the FFC after the FFC is inserted in place.

[0033] Working principle:

[0034] The first step is that when the upright FPC connector with insertion protection is used, the pressing plate 13 is pressed downward, and the pressing plate 13 is forced to squeeze the spring 16, and the spring 16 is deformed by the force. The deformation of the spring 16 releases the limit of the pressing plate 13, and the pressing plate 13 is forced to slide on the fixing rod 15. The sliding of the pressing plate 13 drives the wedge-shaped guide block 14 to move downward, and the wedge-shaped guide block 14 moves downward to contact the guide arm 37. The wedge-shaped guide block 14 moves to squeeze the guide arm 37, and the guide arm 37 is forced to drive the elastic arm 36 to deflect, thereby expanding the space of the card slot 35, and then the FFC is inserted into the card slot 35, and the FFC is released after the FFC is inserted in place. The pressing plate 13 and the spring 16 are reset to drive the pressing plate 13 and the wedge-shaped guide block 14 to reset, and then the guide arm 37 is reset, and then the contact point on the guide arm 37 is close to the corresponding position of the FFC that is inserted into place. By adding a pressing plate 13 to the FPC connector, during the insertion of the FFC, the pressing plate 13 cooperates with the wedge-shaped guide block 14 to drive the guide arm 37 to shift, thereby expanding the space of the card slot 35. The card slot 35 with the expanded space is used to insert the FFC. After the FFC is inserted into place, the guide arm 37 is reset, and the contact point of the guide arm 37 is close to the corresponding position of the FFC, thereby effectively improving the stability of the product during use.

[0035] In the second step, when the upright FPC connector with insertion protection is used, the pressing plate 13 is pressed again, and the pressing plate 13 is forced to squeeze the spring 16, and the spring 16 is deformed under the force, and the limit of the pressing plate 13 is released. The pressing plate 13 slides on the fixed rod 15 and drives the wedge-shaped guide block 14 to move downward. The wedge-shaped guide block 14 moves to squeeze the guide arm 37, and the guide arm 37 is forced to drive the elastic arm 36 to deflect, thereby expanding the space of the card slot 35. At this time, the FFC can be easily pulled out of the card slot 35. After releasing the pressing plate 13, the spring 16 resets and drives the pressing plate 13 and the wedge-shaped guide block 14 back to the initial position. By adding the pressing plate 13 to the FPC connector, the design of the pressing plate 13 facilitates the plugging and unplugging operation of the FFC during the process of pulling out the FFC, and effectively improves the convenience of the product during use.

[0036] In the third step, during the FFC insertion process, the cooperation between the wedge-shaped guide block 14 and the guide arm 37 enables the space of the card slot 35 to be accurately expanded, ensuring that the FFC can be smoothly inserted while avoiding damage to the FFC. The card cavity 22 on the insulating cover 2 is engaged with the card arm 32 on the conductive terminal 31, which enhances the stability of the conductive terminal 31 and prevents it from being displaced during use, ensures good contact between the FFC and the conductive terminal 31, improves the stability of signal transmission, and effectively improves the reliability and service life of the product.

[0037] In the fourth step, when the FFC is inserted into place, the contact point on the guide arm 37 is close to the corresponding position of the FFC, and the snap-in cavity 11 on the insulating body 1 is plugged into the conductive terminal group 3, so that the conductive terminal group 3 is positioned and arranged in the insulating body 1, ensuring the firmness of the connection between the FFC and the conductive terminal group 3. At the same time, the two snap-in pieces 23 are respectively snap-in with the snap-in cavity 2 17 on the insulating body 1 and the snap-in cavity 3 21 on the insulating cover 2, further enhancing the overall stability of the product and effectively improving the stability and reliability of the product during use.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
