Description

Technical Field

[0001] This utility model relates to the field of circuit board connector technology, specifically to a flat flexible circuit board connector. Background Technology

[0002] Flat flexible circuit board connectors are a type of electronic connector specifically designed for connecting flexible printed circuit boards or flat flexible cables.

[0003] In the prior art, such as the flat flexible circuit board connector with authorization number CN2640063Y, the upper sidewall of the flexible circuit board connector is formed by a liftable and flip-up movable cover. The position of the liftable and flipped cover is opposite to the direction of the insertion operation of the flexible circuit board, and terminal channels are opened on the surface of the liftable and flip-up movable cover.

[0004] In the above, the mating of the circuit board is basically achieved by the cooperation between the movable cover and the insertion position. However, after reading the technical solution, it is found that the cover is in direct contact with the insertion position and the edge of the cover is right angled. No corresponding anti-slip component is set on the contact surface. When the two circuit boards are mated, the edge of the end face is easily worn by the cover, which changes the shape and slippage often occurs. Therefore, it is necessary to add anti-slip component for the mating process without changing the circuit board structure. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a flat flexible circuit board connector, which can effectively solve the problem of slippage of two circuit boards and misalignment of the mating position in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a flat flexible circuit board connector, including a mating plate, the side of which is provided with angular teeth, and the mating plate is fitted with an anti-slip component, and a flexible circuit board is snapped onto the side of the mating plate.

[0008] The anti-slip component includes a sliding block that is in close contact with one of the angle teeth. A linear slide rail is slidably fitted on the side of the sliding block. An anti-deviation component is placed on the side of the linear slide rail. A column is fixed on one side of the sliding block. A semi-ring block is rotatably fitted on the outer surface of the column. A locking groove is opened on the side of the semi-ring block, and a locking component is fitted on the semi-ring block.

[0009] Furthermore, the locking component includes a transmission arm fixed to the surface of the semi-ring block, and a positioning shaft is rotatably sleeved at the center of the transmission arm.

[0010] Furthermore, a tension spring is fitted onto the surface of the transmission arm, and a fastening pin is fixed to the end face of the tension spring. The bottom of the fastening pin is embedded in the surface of the mating plate, and the tension distance of the tension spring is greater than the deflection distance of the transmission arm.

[0011] Furthermore, a counterweight ball is fixed to one end of the transmission arm, and the center of the counterweight ball is aligned with the center of the transmission arm.

[0012] Furthermore, an external convex shaft is fixed to the outer side of the semi-annular block, and the external convex shaft is correspondingly arranged with the inner groove of the locking groove.

[0013] Furthermore, the counterweight ball is equipped with a fastening assembly, which includes a side plate that connects to the side of the docking plate. The surface of the side plate has circular grooves that are evenly spaced.

[0014] Furthermore, a bottom plate is fixedly connected to the side of the side plate, and an adapter plate is rotatably sleeved on the bottom plate via a support shaft. The adapter plate is in the shape of an inner curved plate.

[0015] Furthermore, the number of anti-deviation components is two, and the two anti-deviation components are arranged symmetrically.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. By setting angle teeth on the side of the mating plate, the alignment of the mating plate is made more stable, and the sliding block is brought into close contact with the angle teeth. When the angle teeth of the other mating plate are horizontally displaced, the sliding force is quickly canceled by the sliding block and the linear guide rail. The greater the alignment displacement of the mating plate, the more obvious the cancellation effect. In other words, the sliding method of the sliding block can leave sufficient margin for the displacement of the mating plate (the larger the mating margin of the mating plate, the longer the insertion and alignment time, and the less likely it is to slip off). Furthermore, during the displacement of the sliding block, the locking groove and the locking part lock each other, so that the sliding block will not shake, which is conducive to continuously canceling the mating force of the angle teeth, ensuring the stability of the mating plate, and reducing slippage during the mating process.

[0019] Second, the rotation of the transmission arm on the positioning shaft surface can convert the sliding force of the sliding block into rotational force. By observing how many degrees the transmission arm rotates, the magnitude of the docking force of the docking plate can be obtained. The docking force of the docking plate is intuitively reflected, reducing the occurrence of the docking plate having to be docked with force. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-5 A flat flexible circuit board connector includes a mating plate 1, the side of the mating plate 1 is provided with corner teeth 2, and the mating plate 1 is fitted with an anti-slip component 3, and a flexible circuit board 5 is snapped onto the side of the mating plate 1.

[0030] The anti-slip component 3 includes a sliding block 31, which is in close contact with one of the angle teeth 2. A linear slide rail 32 is slidably fitted on the side of the sliding block 31. An anti-deviation component 321 is placed on the side of the linear slide rail 32. A column 33 is fixed on one side of the sliding block 31. A semi-ring block 34 is rotatably fitted on the outer surface of the column 33. A locking groove 341 is opened on the side of the semi-ring block 34. A locking component 35 is fitted on the semi-ring block 34.

[0031] By setting the angle teeth 2 on the side of the docking plate 1, the positioning of the docking plate 1 is more stable, and the sliding block 31 is brought into close contact with the angle teeth 2. When the angle teeth 2 of the other docking plate 1 are horizontally displaced, the sliding force is quickly canceled by the sliding block 31 and the linear slide rail 32. The greater the displacement of the docking plate 1, the more obvious the cancellation effect. In other words, the sliding method of the sliding block 31 can leave sufficient margin for the displacement of the docking plate 1 (the larger the docking margin of the docking plate 1, the longer the insertion and alignment time, and the less likely it is to slip off). Furthermore, during the displacement of the sliding block 31, the locking groove 341 and the locking member 35 lock each other, so that the sliding block 31 will not shake, which is conducive to continuously canceling the docking force of the angle teeth 2, ensuring the stability of the docking plate 1, and reducing slippage during the docking process.

[0032] The locking component 35 includes a transmission arm 351 fixed to the surface of the semi-ring block 34, and a positioning shaft 352 is rotatably sleeved at the center of the transmission arm 351.

[0033] The transmission arm 351 rotates on the surface of the positioning shaft 352, which can convert the sliding force of the sliding block 31 into rotational force. By observing how many degrees the transmission arm 351 rotates, the magnitude of the docking force of the docking plate 1 can be obtained. The docking force of the docking plate 1 is intuitively reflected, reducing the occurrence of the docking plate 1 having to use force to dock.

[0034] A tension spring 353 is fitted onto the surface of the transmission arm 351. A fastening pin 354 is fixed to the end face of the tension spring 353. The bottom of the fastening pin 354 is fitted into the surface of the mating plate 1. The tension distance of the tension spring 353 is greater than the deflection distance of the transmission arm 351.

[0035] By installing a tension spring 353 on the surface of the transmission arm 351, the rotation of the transmission arm 351 becomes more uniform, the docking force of the docking plate 1 is displayed more accurately, and the situation of docking slippage is significantly reduced.

[0036] One end of the transmission arm 351 is fixed with a counterweight ball 355, and the center of the counterweight ball 355 is aligned with the center of the transmission arm 351.

[0037] A counterweight ball 355 is fixedly installed at one end of the transmission arm 351. By increasing the gravity, the repeated jumping of the end face of the transmission arm 351 is reduced, making the deflection of the end face of the transmission arm 351 more stable.

[0038] An external convex shaft 36 is fixed on the outer side of the semi-ring block 34, and the external convex shaft 36 is correspondingly set with the inner groove of the locking groove 341.

[0039] The correspondence between the protruding shaft 36 and the locking groove 341 can enhance the insertion capability of the semi-ring block 34 and ensure that the mating plate 1 can be stably displaced without misalignment or slippage.

[0040] The counterweight ball 355 is fitted with a fastening assembly 4. The fastening assembly 4 includes a side plate 41 that is connected to the side of the docking plate 1. The surface of the side plate 41 is provided with circular grooves, which are distributed in an equidistant manner. A bottom plate 42 is fixedly connected to the side of the side plate 41. The bottom plate 42 is fitted with an adapter plate 43 through a support shaft. The adapter plate 43 is in the shape of an inner curved plate.

[0041] The counterweight ball 355 can be locked in place by the circular groove in the side plate 41, and the transmission arm 351 will remain fixed. When the transmission arm 351 is not moving, the docking plate 1 is released, allowing the docking plate 1 to be aligned in a fixed position, and the adapter plate 43 to be rotated and fitted on the outer surface of the bottom plate 42. This allows the inner curved surface of the adapter plate 43 to contact the spherical surface of the counterweight ball 355, further stabilizing the position of the counterweight ball 355.

[0042] There are two anti-deviation components 321, and the two anti-deviation components 321 are arranged symmetrically.

[0043] The two anti-deviation components 321 ensure that the sliding block 31 always moves along the surface of the linear slide rail 32, preventing it from tilting or sliding to the side.

[0044] Working principle: First, install the flexible circuit board 5 on one side of the docking plate 1, and then take out the two docking plates 1 to realize the docking of the two flexible circuit boards 5.

[0045] During the docking process of the two flexible circuit boards 5, the angle tooth 2 contacts and engages on the outer side of the docking plate 1 to determine the alignment position of the flexible circuit board 5. At the same time, the sliding block 31 moves on the surface of the linear slide rail 32 to determine the alignment direction of the flexible circuit board 5. Then, the outer convex shaft 36 abuts against the locking groove 341. During the abutment process, the outer convex shaft 36 applies force to the semi-ring block 34, causing the semi-ring block 34 to deflect at an angle. Afterward, the semi-ring block 34 drives the transmission arm 351 to deflect synchronously, and the tension spring 353 helps stabilize the deflection of the transmission arm 351.

[0046] Then the transmission arm 351 will drive the counterweight ball 355 at one end to rotate. When the counterweight ball 355 is engaged with the groove on the surface of the side plate 41, the transmission arm 351 stops deflecting, the outer convex shaft 36 is tightly engaged with the locking groove 341, the flexible circuit board 5 is firmly attached, and the slippage is significantly improved.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
