Circuit boards can be called printed circuit boards or printed circuit boards. The English names are PCB and FPC circuit boards. Circuit boards are also called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as a substrate and are highly reliable and extremely flexible printed circuit boards.

[0003] like Figure 1 The liquid crystal display module shown is mainly composed of LCD1-2 and PCB1-4, wherein LCD1-2 is connected by a metal clip PIN1-1, and the metal PIN1-1 needs to pass through PCB1-4 for soldering and fixing. Since the thickness of the clamp of the metal PIN1-1 on the side facing PCB1-4 exceeds the thickness of the lower polarizer in LCD1-2, after the metal PIN1-1 passes through PCB1-4, the clamp of the metal PIN1-1 will hit the PCB1-4, causing the inner glass of LCD1-2 to be unable to contact PCB1-4. In this case, the usual practice is to add a sticky foam 1-3 between LCD1-2 and PCB1-4 to support the glass;

[0004] However, in the process of realizing the combined assembly of LCD and PCB by using the above method, it is found that since sticky foam needs to be attached, the sticking position of the sticky foam needs to be accurately grasped in the actual attachment process, and the precision requirement is high. In addition, the thickness of the sticky foam may be reduced or thickened due to the influence of the use environment during long-term use, so it is impossible to stably achieve effective support for the glass. Therefore, a module combining LCD and PCB with metal PIN connection is proposed. Utility Model Content

[0005] Based on this, it is necessary to provide a module combining LCD and PCB connected by metal PINs to address the above technical problems, and to open an avoidance groove on the PCB module, thereby ensuring that during the assembly process of the LCD module and the PCB module, there is no need to use sticky foam for support.

[0013] Furthermore, the number of the arched grooves is several and they are evenly distributed along the length direction of the rectangular groove.

[0014] Furthermore, the metal clip PIN includes a metal clip head and a clip tail, and the clip tail extends in the arched groove toward the direction of the LCD module.

[0015] Furthermore, the clip tail of the metal clip PIN passes through the arched groove and is welded to the back side of the PCB module to form a welding point.

[0016] Further, the LCD module includes an upper polarizer, an upper glass, a lower glass and a lower polarizer;

[0038] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0039] As mentioned in the background art, it is found that during the assembly process of LCD and PCB using the traditional method, since sticky foam needs to be attached, the sticking position of the sticky foam needs to be accurately controlled during the actual attachment process, and the precision requirement is high. In addition, during long-term use, the thickness of the sticky foam may be affected by the use environment and may shrink or thicken, so it is impossible to stably provide effective support for the glass.

[0040] In order to solve this technical problem, the utility model provides a module combining LCD and PCB connected by metal PIN, which is applied to the combined assembly of LCD and PCB.

[0041] Specifically, please refer to Figure 1-Figure 8 The modules combining LCD and PCB with metal PIN connection include:

[0042] LCD module 1, with a metal clip PIN 2 buckled at the edge of the LCD module 1;

[0043] PCB module 5, which is arranged on one side of LCD module 1 and connected thereto via metal clip PIN2;

[0044] The avoidance groove 3 is provided on the PCB module 5 at a position corresponding to the metal clip PIN 2 , and is used to avoid the metal clip PIN 2 when the LCD module 1 is mounted on the PCB module 5 .

[0045] The LCD and PCB combined module connected by metal PIN provided by the utility model is provided with an avoidance groove 3 on the PCB module 5, which not only realizes that during the bonding and assembly process of the LCD module 1 and the PCB module 5, there is no need to use sticky foam for support, which simplifies the assembly steps to a certain extent and eliminates the need for precision sticky foam pasting operations. At the same time, the metal clip pin 2 on the LCD module 1 can be avoided through the avoidance groove 3, so that it partially avoids in the avoidance groove 3, and forms a bonding support with the corresponding PCB module 5. Compared with the traditional method of using sticky foam for pasting support, it effectively ensures the relative stability between the contact support of the LCD module 1 and the PCB module 5, and satisfies its stable display use.

[0046] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0049] Please refer to Figure 2-Figure 4 A module combining an LCD and a PCB connected by metal PINs, comprising an LCD module 1, wherein a metal clip PIN 2 is buckled at the edge of the LCD module 1; a PCB module 5, which is arranged at one side of the LCD module 1 and connected thereto through the metal clip PIN 2; and an avoidance groove 3, which is provided at a position on the PCB module 5 corresponding to the metal clip PIN 2, and is used to avoid the metal clip PIN 2 when the LCD module 1 is fitted and installed on the PCB module 5.

[0050] Please refer to Figure 5 , 6 The avoidance slot body 3 includes a rectangular slot 31 and an arched slot 32, and the arched slot 32 is connected to the rectangular slot 31;

[0051] The number of the arched grooves 32 is several and they are evenly distributed along the length direction of the rectangular groove 31;

[0052] The metal clip PIN2 includes a metal clip head 21 and a clip tail 22. The clip tail 22 extends in the direction of the LCD module 1 in the arched groove 32. Through the design of multiple arched grooves 32, when the LCD module 1 and the PCB module 5 are assembled, the clip tails 22 on the multiple metal clip PIN2 on the LCD module 1 will be respectively placed in the corresponding arched grooves 32, thereby forming independent separation of the multiple metal clip PIN2 through the arched groove 32, which facilitates the subsequent independent welding operation to a certain extent.

[0053] When the LCD module 1 is assembled on the PCB module 5, the clip tail 22 on the metal clip PIN2 connected to the LCD module 1 will pass through the corresponding arched groove 32, and when the LCD module is finally attached to the PCB module 5, the metal clip head 21 on the metal clip PIN2 will be partially accommodated in the corresponding rectangular groove 31, so that there is no need to use sticky foam to support the LCD module 1, and there is no need to accurately paste the sticky foam, and there is no need to consider the subsequent shortening or increase of the thickness of the sticky foam, which is not conducive to the stable support of the LCD module 1, thereby ensuring the stable use between the LCD module and the PCB module 5 after the assembly is completed;

[0054] The clip tail 22 of the metal clip PIN2 passes through the arched groove 32 and is welded to the back of the PCB module 5 to form a solder joint 23. Figure 2 As shown, after the clip tail 22 on the metal clip PIN2 passes through the arched groove 32, the clip tail 22 and the PCB module 5 can be welded and connected on the back of the PCB module 5;

[0055] The LCD module 1 includes an upper polarizer 11, an upper glass 12, a lower glass 13 and a lower polarizer 14, wherein the upper polarizer 11, the upper glass 12, the lower glass 13 and the lower polarizer 14 are sequentially attached to form the LCD module 1;

[0056] like Figure 1 As shown, the metal clamps 21 on the plurality of metal clamps PIN2 are buckled on the edge of the surface of the lower glass 13 .

[0057] The LCD and PCB combined module provided in Example 1 with metal PIN connection is further optimized. Specifically, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the surface of the clip tail 22 is provided with a positioning member 4 for separating and positioning the multiple clip tails 22;

[0058] The positioning member 4 includes an insulating positioning sleeve 41 . A clamping platform 42 is connected to the insulating positioning sleeve 41 in a direction facing the LCD module 1 . The insulating positioning sleeve 41 is clamped in the arched groove 32 through the clamping platform 42 .

[0059] Through the above structural design, after the LCD module 1 is assembled on the PCB module 5, the clip tail 22 is located on the back of the PCB module 5. At this time, the insulating positioning sleeve 41 can be sleeved on the surface of the clip tail 22, and then the insulating positioning sleeve 41 is clamped in the corresponding arch groove 32 through the clamping table 42, so that the soldering liquid can be blocked to a certain extent during the process of welding the clip tail 22 and the PCB module 5 to each other, and the blocked soldering liquid can be prevented from directly falling into the rectangular groove 31 and affecting the connection and use of the LCD module 1 and the metal clip PIN2.

[0060] The LCD and PCB combined module provided by the metal PIN connection provided in Example 1 or 2 is further optimized, such as Figure 5 , Figure 6 and Figure 7 As shown, a blocking boss 43 is formed at the edge of the top of the insulating positioning sleeve 41 to block the welding liquid during welding;

[0061] As a further optimization of this embodiment: Since the soldering liquid itself has a certain tension effect, the design of the blocking boss 43 on the side of the clip tail 22 close to the rectangular groove 31 can effectively block the situation where the soldering liquid directly falls into the rectangular groove 31 during the soldering process, thereby ensuring the concentration of the soldering liquid and ensuring the stability of the soldering at the soldering point between the clip tail 22 and the PCB module 5;

[0062] Through the above operation, the soldering liquid is prevented from directly falling into the rectangular groove 31 through the opening of the arched groove 32 close to the outer side of the rectangular groove 32. In addition, because the soldering liquid has a certain tension, the gap formed between the clip tail 22 and the arched groove 32 can ensure that the soldering liquid is not easy to pass through, thereby forming an effective barrier effect.

[0063] The LCD and PCB combined module provided by the metal PIN connection provided in Example 3 is further optimized, such as Figure 8 As shown, the bottom of the insulating positioning sleeve 41 is formed with an arc-shaped surface platform 44;

[0064] Through the design of the arc-shaped surface platform 44, when the LCD module 1 is not connected and assembled with the PCB module 5, the insulating positioning sleeve 41 can be firstly engaged with the inside of the arched groove 32 through the clamping platform 42, and then when the metal clip PIN2 on the LCD module 1 passes through the arched groove 32, it can directly pass through the insulating positioning sleeve 41 to perform subsequent welding.

[0065] In the above operation process, multiple positioning members 4 can also be connected to each other so that the multiple positioning members 4 are connected as one, and then the positioning members 4 connected as one can be directly installed in the arched groove 32 to wait for the clip tail 22 to pass through;

[0066] Alternatively, the clip tail 22 may be passed through the arched groove 32 first, and then the multiple positioning members 4 connected as one are directly sleeved on the surfaces of the multiple metal clip PINs 2. The specific assembly steps of the positioning members 4 may be reasonably selected according to the actual situation.

[0067] Through the design of the above-mentioned arc-shaped surface platform 44, the insulating positioning sleeve 41 can be guided when the positioning member 4 is sleeved on the clamp tail 22. Similarly, it can also play a guiding role when the clamp tail 22 passes through the insulating positioning sleeve 41, thereby making it more convenient to assemble the insulating positioning sleeve 41 and the clamp tail 22 relative to each other.

[0068] The use process of the LCD and PCB combined module connected by metal PIN provided by the utility model is as follows: when the LCD module 1 with the metal clip PIN2 is attached to the PCB module 5 for installation, the tail of the metal clip PIN2 during the installation process passes through the arch groove 32 and is partially located in the rectangular groove 31, so that the LCD module 1 can be completely attached to the surface of the PCB module 5 to form a stable and effective supporting state.

[0069] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
