Abstract
Description
Technical Field
[0001] This utility model relates to the field of LCD module technology, and in particular to a metal clip PIN structure for LCD modules. Background Technology
[0002] An LCD module (LCM) is a display assembly that integrates liquid crystal display devices, connectors, integrated circuits, control and driving circuits, PCB circuit boards, backlights, and structural components. It is an LCD display product that integrates the glass and LCD driver, providing users with a standard LCD display driving interface through which users can control the correct display of the LCD.
[0003] like Figure 7 and Figure 8 The LCD1-1 shown has an ITO PAD1-2. One end of the ITO PAD1-2 is connected to the display pattern of the LCD, and the other end needs to be inserted into a metal clip PIN1-3. The metal clip PIN1-3 is then soldered to the terminal device. Since the clamping opening 1-4 of the conventional metal clip PIN1-3 is arc-shaped, its contact area with the LCD1-1 is a line between the arc-shaped clamping opening 1-4 and the glass substrate plane. After long-term use, the metal clip PIN1-3 will oxidize and corrode, which can easily lead to poor contact between the metal clip PIN1-3 and the ITO PAD1-2. This will cause the control signal of the LCD1-1 to be disconnected, making the LCD unable to work properly. Therefore, a metal clip PIN structure for LCD modules is proposed. Utility Model Content
[0004] Therefore, it is necessary to address the aforementioned technical problems by providing a metal clip PIN structure for LCD modules. This structure changes the conventional arc-shaped contact between the metal clip PIN and the glass substrate to a straight edge, thereby changing the contact area between the metal clip PIN and the glass substrate from a line to a rectangle. This increases the contact area between the PIN clip and the glass, improving the connection reliability between the metal clip PIN and the LCD glass substrate.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A metal clip PIN structure for an LCD module includes an LCD glass module, wherein the LCD glass module has an ITO PAD for connecting to an LCD display pattern, and a metal clip PIN is connected to the ITO PAD.
[0007] The metal clip PIN includes a clamping front end and a soldering tail end;
[0008] The clamping front end has a clamping opening on its surface, and the clamping opening is connected to the clearance groove in the clamping front end. There is a clamping plane between the clamping opening and the clearance groove. The clamping plane can make the metal clamping pin and the LCD glass module make surface contact and clamp.
[0009] Furthermore, the clamping front end includes a left clamping arm and a right clamping arm;
[0010] The clamping opening and the clearance groove are both located between the left clamping arm and the right clamping arm.
[0011] Furthermore, the top ends of both the left and right clamping arms are formed with guide arc surfaces, and the clamping opening is located between the two guide arc surfaces.
[0012] Furthermore, the bottom ends of the left clamping arm and the right clamping arm are formed with clearance arc surfaces, and the clearance groove is located between the two clearance arc surfaces.
[0013] Furthermore, the two clamping planes are respectively distributed in the middle of the left clamping arm and the right clamping arm.
[0014] Furthermore, the two ends of the clamping plane are respectively transitionally connected to the corresponding guide arc surface and avoidance arc surface.
[0015] Furthermore, the width formed between the two clamping planes is smaller than the width of the clamping opening and the clearance groove.
[0016] Furthermore, the welding tail end and the clamping front end are distributed at a 90-degree angle.
[0017] Furthermore, the LCD glass module includes an upper glass substrate and a lower glass substrate bonded together, and an upper polarizer and a lower polarizer are respectively bonded to the outer sides of the upper glass substrate and the lower glass substrate.
[0018] Furthermore, one end of the lower glass substrate extends beyond one end of the upper glass substrate to form a single-layer region, the ITO PAD is distributed on the single-layer region, and the clamping plane of the metal clip PIN is clamped on the ITO PAD and connected to the LCD glass module.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The metal clip PIN structure for LCD modules provided by this utility model changes the contact surface between the metal clip PIN and the lower glass substrate from the conventional arc shape to a straight edge, so that the contact area between the metal clip PIN and the lower glass substrate changes from the conventional linear contact to a rectangular contact. This increases the contact area between the metal clip PIN and the lower glass substrate, which not only improves the connection reliability between the metal clip PIN and the LCD glass module, but also makes the metal clip PIN clamp more firmly and less likely to fall off due to the increased contact area.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0034] As described in the background art, such as Figure 7 and Figure 8 The LCD1-1 shown has an ITO PAD1-2. One end of the ITO PAD1-2 is connected to the display pattern of the LCD, and the other end needs to be inserted into a metal clip PIN1-3. The metal clip PIN1-3 is then soldered to the terminal device. Since the clamping opening 1-4 of the conventional metal clip PIN1-3 is arc-shaped, its contact area with the LCD1-1 is a line between the arc-shaped clamping opening 1-4 and the glass substrate plane. After long-term use, the metal clip PIN1-3 will oxidize and corrode, which can easily lead to poor contact between the metal clip PIN1-3 and the ITO PAD1-2. This will cause the control signal of the LCD1-1 to be disconnected, making the LCD unable to work properly.
[0035] To solve this technical problem, this utility model provides a metal clip PIN structure for LCD modules, which is applied to LCD modules.
[0036] For details, please refer to Figures 1-8 The metal clip PIN structure for the LCD module specifically includes an LCD glass module 1, an ITO PAD 11 for connecting to the LCD display pattern, and a metal clip PIN 2 connected to the ITO PAD 11.
[0037] The metal clip PIN2 includes a clamping front end 21 and a welding tail end 22;
[0038] The clamping front end 21 has a clamping opening 23 on its surface, and the clamping opening 23 is connected to the relief groove 24 in the clamping front end 21. A clamping plane 25 is provided between the clamping opening 23 and the relief groove 24. The clamping plane 25 can make the metal clamp PIN2 and the LCD glass module 1 make surface contact and clamp.
[0039] The metal clip PIN structure for LCD modules provided by this utility model changes the contact surface between the metal clip PIN2 and the lower glass substrate 13 from a conventional arc shape to a straight edge contact. This changes the contact area between the metal clip PIN2 and the lower glass substrate 13 from a conventional linear contact to a rectangular contact, thereby increasing the contact area between the metal clip PIN2 and the lower glass substrate 13. This not only improves the reliability of the connection between the metal clip PIN2 and the LCD glass module 1, but also makes the metal clip PIN2 clamp more firmly and less likely to fall off due to the increased contact area.
[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0043] Example 1
[0044] Please refer to Figures 1-6 A metal clip PIN structure for an LCD module includes an LCD glass module 1, an ITO PAD 11 on the LCD glass module 1 for connecting to an LCD display pattern, and a metal clip PIN 2 connected to the ITO PAD 11.
[0045] The metal clip PIN2 includes a clamping front end 21 and a welding tail end 22;
[0046] like Figure 8 As shown, when a conventional metal clip PIN is clamped to an LCD glass module, the contact surface is a line contact. Because the inner side of the conventional metal clip PIN is an inwardly convex arc shape, the contact area after contacting the LCD glass module is small. As a result, the contact surface is prone to oxidation and corrosion during subsequent long-term use, leading to poor contact between the metal clip PIN and the ITO PAD, and signal interruption of the entire module.
[0047] Therefore, in this embodiment, the conventional arc-shaped metal frame PIN is changed to a planar contact state, thereby increasing the contact area, as detailed below:
[0048] like Figure 2 and Figure 4As shown, the surface of the clamping front end 21 has a clamping opening 23, and the clamping opening 23 is connected to the relief groove 24 in the clamping front end 21. There is a clamping plane 25 between the clamping opening 23 and the relief groove 24. The metal clamp PIN2 can be clamped to the LCD glass module 1 in surface contact by the action of the clamping plane 25.
[0049] After the metal clip PIN2 is clamped to the LCD glass module 1, the clamping plane 25 on the metal clip PIN2 makes contact with the surface of the LCD glass module 1, and the contact surface is rectangular, thereby increasing the effective contact area and improving the conduction stability of the metal clip PIN2.
[0050] Example 2
[0051] The metal clip PIN structure for LCD modules provided in Embodiment 1 is further optimized, specifically, as follows: Figure 5 and Figure 6 As shown, the clamping front end 21 includes a left clamping arm 210 and a right clamping arm 211. In this embodiment, the clamping front end 21 is divided into a left clamping arm 210 and a right clamping arm 211. This is only a distinction in name. In the actual manufacturing process, the metal clip PIN2 is manufactured as a single piece.
[0052] The clamping opening 23 and the clearance groove 24 are both located between the left clamping arm 210 and the right clamping arm 211.
[0053] The top ends of the left clamping arm 210 and the right clamping arm 211 are both formed with guide arc surfaces 212, and the clamping opening 23 is located between the two guide arc surfaces 212.
[0054] With the design of the guide arc surface 212, when the metal clip PIN2 is clamped on the LCD glass module 1, the clamping opening 23 is aligned with the appropriate position so that the metal clip PIN2 can be pushed. During the pushing process, the guide arc surface 212 can cause the clamping opening 23 to open, so that the metal clip PIN2 is completely clamped to the surface of the LCD glass module 1 to form a connection.
[0055] The bottom ends of the left clamping arm 210 and the right clamping arm 211 are formed with relief arc surfaces 213, and the relief groove 24 is located between the two relief arc surfaces 213.
[0056] By designing the avoidance arc surface 213, after the metal clip PIN2 is inserted and clamped onto the LCD glass module 1, the edge of the LCD glass module 1 can be located within the avoidance groove 24 of the metal clip PIN2. Since the size of the avoidance groove 24 is larger than the thickness of the contact position with the LCD glass module 1, it can form an avoidance effect, so that the metal clip PIN2 only contacts the ITO PAD11 on the LCD glass module 1 through the clamping plane 25.
[0057] The two clamping planes 25 are respectively distributed in the middle of the left clamping arm 210 and the right clamping arm 211, and the two ends of the clamping planes 25 are respectively connected to the corresponding guide arc surface 212 and avoidance arc surface 213.
[0058] In its natural state, the gap between the two clamping planes 25 is slightly smaller than the thickness of the clamping position on the LCD glass module 1. This allows the metal clip PIN2 to unfold after clamping the LCD glass module 1, thus giving it a tendency to close and reset. This effectively increases the clamping strength between the metal clip PIN2 and the LCD glass module 1, preventing it from falling off.
[0059] The width formed between the two clamping planes 25 is smaller than the width of the clamping opening 23 and the clearance groove 24. Through the width design, after the metal clamp PIN2 contacts the ITO PAD11 on the LCD glass module 1, only the clamping plane 25 contacts the ITO PAD11, and other positions do not contact the metal clamp PIN2 (except for the inner bottom wall of the clearance groove 24).
[0060] The welding tail end 22 is positioned at a 90-degree angle to the clamping front end 21.
[0061] Example 3
[0062] The metal clip PIN structure for LCD modules provided in Embodiment 1 or 2 is further optimized, such as... Figure 2 As shown, the LCD glass module 1 includes an upper glass substrate 12 and a lower glass substrate 13 that are bonded together. An upper polarizer 14 and a lower polarizer 15 are respectively bonded to the outer sides of the upper glass substrate 12 and the lower glass substrate 13.
[0063] One end of the lower glass substrate 13 extends beyond one end of the upper glass substrate 12 to form a single-layer region 16. The ITO PAD 11 is distributed on the single-layer region 16, and the clamping plane 25 of the metal clip PIN 2 is clamped on the ITO PAD 11 and connected to the LCD glass module 1.
[0064] In practical applications, one end of the ITO PAD11 is first connected to the LCD display pattern, and then the metal clip PIN2 is clamped at the position of the ITO PAD11 on the lower glass substrate 13, so that the other end of the ITO PAD11 is connected to the lower glass substrate 13. At this time, the clamping plane 25 on the inner side of the metal clip PIN2 and the contact surface of the ITO PAD11 are in a planar state, which increases the effective contact area and improves the overall conductivity stability of the module.
