Description

Technical Field

[0001] This utility model relates to the technical field of flexible circuit board connection mechanisms, specifically a vibration-resistant flexible circuit board connection mechanism for TFT LCD screens. Background Technology

[0002] A TFT liquid crystal display is an active matrix liquid crystal display that uses thin-film transistors to drive each liquid crystal pixel. The display uses flexible circuits to connect the various components, and the connection mechanism of the flexible circuit board is in the form of plugs and sockets (i.e., terminals).

[0003] Existing flexible circuit board connection mechanisms directly use terminal mating when connecting electrical components and functional parts of the flexible circuit board. The plug end and socket end of the terminal are equipped with anti-dislodgement clips. However, the clips act directly on the terminal joint. When subjected to vibration, the overall connection stability is reinforced by the terminal joint through the clips. In other words, the end part is directly subjected to vibration. Long-term stress on the end part may also lead to damage. Vibration may also cause the clips at the terminal joint to loosen, resulting in displacement or direct detachment, affecting the stability of the terminal connection. After displacement, gaps will also appear at the splice between the plug and the socket, ultimately leading to the terminal loosening and affecting the stability of the connection.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a vibration-resistant flexible circuit board connection mechanism for TFT LCD screens. Utility Model Content

[0005] The purpose of this invention is to provide a vibration-resistant flexible circuit board connection mechanism for TFT LCD screens to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a TFT LCD screen vibration-resistant flexible circuit board connection mechanism, including a connection socket, a connection plug provided on the front side of the connection socket, a protrusion fixedly connected to the front side of the outer surface of the connection socket and the rear side of the outer surface of the connection plug, spring pieces fixedly connected to the front sides of the left and right ends of the protrusion on the surface of the connection socket, a locking block fixedly connected to the front end of each spring piece, and mating grooves provided on the left and right sides of the protrusion on the surface of the connection plug.

[0007] Preferably, the thickness and length of the spring piece are matched with the mating groove, and the shape of the locking block is set as a right-angled triangle.

[0008] Preferably, the front surface of the connector socket has a connecting groove for a matching connector plug end, and a rubber pad is fixedly connected around the inner surface of the connecting groove.

[0009] Preferably, a groove is provided in the middle of the upper part of the protrusion on the surface of the connector socket, and a movable plate is rotatably connected to the inner surface of the groove through a damping shaft.

[0010] Preferably, the movable plate is L-shaped, and a cover is fixedly connected to the lower end of the vertical rod of the movable plate.

[0011] Preferably, the cover is made of transparent plastic, and the surface of the cover is provided with a magnetic block that is magnetically connected to the connector socket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of protrusions, spring pieces, locking blocks, and mating grooves, allows the protrusions to fit together when the connector socket and connector plug are connected. At this time, the spring pieces will extend into the mating groove. The inner wall of the mating groove will use the inclined surface to push the locking block, causing the spring pieces to expand outward. When the spring pieces are fully inserted into the mating groove, the locking block is located at the front of the mating groove. Without the limitation of the inner wall of the mating groove, the spring pieces will use elastic force to reset. Thus, the locking block will lock the protrusion of the connector plug from front to back, which can further lock the connector socket and connector plug together. This makes the connector socket and connector plug more secure after being plugged in. Even if vibration occurs, the connector socket and connector plug will not easily separate, improving the overall stability of the connection.

[0014] 2. This utility model, through the setting of rubber pads, movable plates, and caps, ensures that when the entire connection mechanism is subjected to vibration, the plug-in ends of the connector socket and connector plug are adhered by the rubber pads. When the rubber pads are vibrated, the interaction between the rubber molecules hinders the movement of the molecular chains, thus exhibiting the characteristics of viscous damping. This buffers the vibration force at the plug-in ends, thereby weakening the vibration and ensuring the stability of the plug-in connection. At the same time, when the connector socket is not in use, the connecting groove can be sealed by rotating the cap with the movable plate to prevent dust and moisture from entering, thus improving the safety of the entire connection mechanism when idle.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, a TFT LCD screen vibration-resistant flexible circuit board connection mechanism includes a connection socket 1, a connection plug 2 is provided on the front side of the connection socket 1, a protrusion 3 is fixedly connected to the front side of the outer surface of the connection socket 1 and the rear side of the outer surface of the connection plug 2, spring pieces 4 are fixedly connected to the front sides of the left and right ends of the protrusion 3 on the surface of the connection socket 1, a locking block 5 is fixedly connected to the front end of the spring piece 4, and a mating groove 6 is provided on the left and right sides of the protrusion 3 on the surface of the connection plug 2.

[0021] By adopting the above technical solution, when the connector socket 1 and the connector plug 2 are connected, the protrusions 3 fit together. At this time, the spring piece 4 will extend into the docking groove 6. The inner wall of the docking groove 6 will use the inclined surface to push the locking block 5, causing the spring piece 4 to expand outward. When the spring piece 4 is fully inserted into the docking groove 6, the locking block 5 is located at the front of the docking groove 6 and loses the restriction of the inner wall of the docking groove 6. The spring piece 4 will reset using elastic force, so that the locking block 5 will lock the protrusion 3 of the connector plug 2 from front to back, thereby further locking the connector socket 1 and the connector plug 2.

[0022] Furthermore, the thickness and length of the spring piece 4 are matched with the mating groove 6, and the shape of the locking block 5 is set as a right-angled triangle.

[0023] By adopting the above technical solution, after the spring piece 4 is fully inserted into the docking groove 6, the rear side of the locking block 5 can fit perfectly against the front side of the protrusion 3 on the surface of the connector plug 2, and the spring piece 4 makes up for the recessed space of the docking groove 6, making the appearance more flat after connection.

[0024] Furthermore, the front surface of the connector socket 1 is provided with a connector groove 7 for the plug end of the matching connector plug 2, and rubber pads 8 are fixedly connected around the inner surface of the connector groove 7.

[0025] By adopting the above technical solution, the connector socket 1 and the connector plug 2 are connected by the connector groove 7;

[0026] The rubber pad 8 covers the plug end of the connector 2. When the rubber pad 8 is vibrated, the interaction between the rubber molecules hinders the movement of the molecular chain, thus exhibiting the characteristics of viscous damping. This buffers the vibration force at the plug end, thereby weakening the vibration.

[0027] Furthermore, a groove 9 is provided in the upper center of the protrusion 3 on the surface of the connector socket 1, and a movable plate 10 is rotatably connected to the inner surface of the groove 9 via a damping shaft.

[0028] By adopting the above technical solution, the movable plate 10 connected by the damping shaft will not rotate arbitrarily.

[0029] Furthermore, the movable plate 10 is shaped like an "L", and a cover 11 is fixedly connected to the lower end of the vertical rod of the movable plate 10; the cover 11 is made of transparent plastic material, and a magnetic block is provided on the surface of the cover 11 to connect with the connection socket 1 by magnetic attraction.

[0030] By adopting the above technical solution, when the connection socket 1 is not in use, the cover 11 can be rotated by the movable plate 10 to seal the connection slot 7 and prevent dust and moisture from entering.

[0031] Working principle: When using the TFT LCD screen vibration-resistant flexible circuit board connection mechanism, firstly, by rotating the movable plate 10, the cover 11 is flipped upwards and opened. The plug end of the connector 2 is aligned with the connecting slot 7 of the connector socket 1 and inserted. When the connector socket 1 and connector 2 mate, the protrusions 3 fit together. At this time, the spring piece 4 extends into the mating slot 6. The inner wall of the mating slot 6 uses the inclined surface to push the locking block 5, causing the spring piece 4 to expand outwards. When the spring piece 4 is fully inserted into the mating slot 6, the locking block 5 is located at the front of the mating slot 6. Without the restriction of the inner wall of the mating slot 6, the spring piece 4 will use elastic force to reset, thereby locking the protrusion 3 of the connector 2 from front to back, thus further connecting the connector. Locking the socket 1 and connector 2 ensures a more secure connection. Simultaneously, the insertion points of the socket 1 and connector 2 are abutted by rubber pads 8. When vibrating, the interaction between rubber molecules in the rubber pads 8 hinders the movement of the molecular chains, exhibiting viscous damping characteristics. This buffers the vibration force at the insertion points, thus reducing vibration. After removing the connector 2, the connection slot 7 of the socket 1 is empty. At this point, the movable plate 10 can be rotated downwards to cover the connection slot 7 with the cover 11, sealing and protecting the socket 1. This is the working principle of the TFT LCD screen vibration-resistant flexible circuit board connection mechanism.
