[0028] The following description provides specific details of various embodiments of this application to enable those skilled in the art to fully understand and implement the various embodiments of this application. It should be understood that the technical solutions of this application can be implemented without some of these details. In some cases, this application does not show or describe in detail some well-known structures or functions to avoid such unnecessary descriptions obscuring the description of the embodiments of this application. The terminology used in this application should be understood in its broadest and most reasonable manner, even when used in conjunction with specific embodiments of this application.

[0029] Figure 1 The figure shows a partial top view of the connection component provided according to the comparative example of this application. Figure 2 The diagram illustrates along Figure 1 A partial cross-sectional view obtained by the dashed lines A1-A2. (See figure.) Figure 1 and Figure 2 As shown, the connection assembly includes a connector 100 and a connection board 200. The connector 100 can be a board-to-board (BTB) connector, thereby electrically connecting the connection board 200 to another circuit board. The connector includes a connector body 100a and pins 100c. The connector 100 can be fixed to the surface of the connection board 200 by, for example, surface mount technology (SMT). In this case, the pins 100c of the connector can be fixed to the surface of the connection board 200 by solder 100b. The connection assembly provided by this comparative example can be applied to a display device. For example, the connection assembly can connect a display module and a controller for controlling the display module. However, during the drop test of the entire display device before it leaves the factory, connector breakage is often a problem.

[0030] According to an embodiment of this application, a connection assembly includes a connection plate and a connector. The connector includes a connector body and pins. The connector body is attached to the surface of the connection plate via the pins. The connector body includes an outer sidewall extending from the surface toward the connector body. The connection assembly also includes a reinforcing structure attached to the outer sidewall and the surface. It is understood that the phrase "the reinforcing structure is attached to the outer sidewall and the surface" does not mean that the reinforcing structure must cover the entire outer sidewall or the entire surface of the connection plate. Rather, the reinforcing structure may only cover a portion of the outer sidewall of the connector body and a portion of the surface of the connection portion. Figure 3 The figure shows a partial top view of the connection component provided according to an embodiment of this application. Figure 4 The diagram illustrates along Figure 3 A partial cross-sectional view obtained through dashed lines B1-B2. The connection assembly includes a connection plate 200 and a connector 100. The connector includes a connector body 100a and pins 100c. The connector body 100a is attached to a surface 200s of the connection plate 200 via the pins. The connector body 100a includes an outer sidewall w extending from the surface 200s in a direction away from the connection plate 200. The connection assembly also includes a reinforcing structure 300, which is attached to the outer sidewall w and the surface 200s. The reinforcing structure 300 enhances the connection strength between the connector and the connection plate, enabling the connector to resist stronger impact and shear forces, thereby improving the connector's drop resistance.

[0031] In some embodiments, the reinforcing structure 300 is disposed on at least one side of the connector body. That is, the reinforcing structure 300 may be disposed on one or more sides of the connector body. The reinforcing structure 300 may also be distributed on all sides of the connector body, in which case the reinforcing structure 300 surrounds the connector body. For example, as... Figure 3 As shown, the connector body's orthographic projection onto the connecting plate is approximately rectangular, and the reinforcing structure 300 surrounds the connector body. In other words, in this embodiment, the reinforcing structure 300 is arranged along the outer sidewall of the connector body around the connector, thereby further enhancing the connection strength between the connector and the connecting plate and further improving the connector's drop resistance.

[0032] In some embodiments, connector 100 can be electrically connected to another connecting plate or circuit board. For example, the other connecting plate or circuit board may include another connector that mates with or cooperates with connector 100. In this case, one of the other connectors can be referred to as a male connector, and the other can be referred to as a female connector. When connector 100 mates with the other connector, electrical connection between connecting plate 200 and the aforementioned other connecting plate or circuit board is achieved. In some embodiments, the height of the reinforcing structure along a first direction perpendicular to the surface is less than the height of the outer sidewall of the connector body in the first direction. For example, referring to… Figure 4 The reinforcing structure 300 extends in a first direction perpendicular to the surface 200s of the connector body, and the height of the reinforcing structure 300 in the first direction is less than the height of the outer side wall w of the connector body in the first direction. That is, the reinforcing structure 300 does not extend to the surface of the connector body 100a away from the connecting plate 200, thereby reducing or avoiding the influence of the reinforcing structure 300 on the connection between the connector 100 and the aforementioned other connection.

[0033] In some embodiments, a reinforcing structure surrounds the connector body, the reinforcing structure including a first portion and a second portion opposite to each other, and a third portion and a fourth portion opposite to each other. The width of the first portion and the second portion in a second direction parallel to the surface is greater than or equal to the height of the outer wall of the connector body in the first direction perpendicular to the surface and less than or equal to twice the height of the outer wall. The width of the third portion and the fourth portion in a third direction parallel to the surface is greater than or equal to the height of the outer wall of the connector body in the first direction perpendicular to the surface and less than or equal to twice the height of the outer wall. The second direction is perpendicular to the third direction. In some embodiments, the width of the reinforcing structure in the second direction parallel to the aforementioned surface of the connecting plate is less than or equal to 0.8 mm. See again... Figure 3To illustrate the second direction here. For example... Figure 3 As shown, the reinforcing structure 300 is arranged around the connector along the outer sidewall of the connector body. The reinforcing structure 300 includes a first portion 300a and a second portion 300b opposite to each other, and a third portion 300c and a fourth portion 300d opposite to each other. The width of the first portion 300a and the second portion 300b in a second direction parallel to the surface is... Figure 3 The third portion 300c and the fourth portion 300d are designated as X2 and X1, respectively, and their widths in a third direction parallel to the surface are designated as Y1 and Y2. In some embodiments, each of the widths X1, X2, Y1, and Y2 is less than or equal to 0.8 mm. In some embodiments, the reinforcing structure 300 includes a photosensitive adhesive layer. Table 1 below shows experiments conducted on a connection assembly provided based on an embodiment of this application and the connection assembly described in the foregoing comparative example. In this exemplary experiment, the connection assemblies in both the comparative example and the embodiment of this application are applied in a display device, and the connection assemblies connect the display module and the controller for controlling the display module, respectively, thereby realizing the electrical connection between the display module and the controller.

[0034] Table 1

[0035]

[0036]

[0037] In Table 1 above, X1 and X2 represent the widths of the first and second parts of the aforementioned reinforcing structure in the second direction, respectively; Y1 and Y2 represent the widths of the third and fourth parts of the aforementioned reinforcing structure in the third direction, respectively; and Z represents the height of the reinforcing structure along the first direction perpendicular to the surface of the connecting plate. Table 1 shows experimental data from five comparative experiments. The rightmost column of data in Table 1 represents data based on... Figure 1 and Figure 2 The push-pull force test results of the embodiment of the connecting component shown are presented in Table 1, with the data in column 7 representing the results based on... Figure 3 and Figure 4 The push-pull force test results of the embodiment of the connecting component shown are presented. The last row of Table 1 also gives the average data of 5 comparative experiments. As can be seen from Table 1 above, in the case where the connecting component does not include a reinforcing structure (such as...), Figure 1 and Figure 2 (As shown in the comparative example), the maximum push-pull force that the connector can withstand corresponds to an average object mass of 6.956 kg, while in cases where the connecting components include reinforcing structures (such as...) Figure 3 and Figure 4In the embodiment shown, the maximum push-pull force that the connector can withstand corresponds to an average object mass of 13.424 kg. Therefore, based on Figure 3 and Figure 4 The described embodiments can significantly enhance the connection strength between the connector and the connecting plate, and improve the connector's drop resistance. According to actual test data, compared to applications based on... Figure 1 and Figure 2 The display device with the connection component shown in the embodiment is based on... Figure 3 and Figure 4 The ability of the display device of the connection component in the illustrated embodiment to withstand external push and pull forces can be improved by about 93%. Therefore, by setting the reinforcing structure as described above, the impact resistance of the connector can be improved.

[0038] Table 2

[0039]

[0040]

[0041] In some embodiments, push-pull force tests were also conducted on connecting components with different reinforcement structure heights to analyze the impact of reinforcement structure height on the drop resistance of the connecting components. As shown in Table 2, reinforcement structures of different heights can be set according to the height T of the outer wall of the connector body. In the experimental data corresponding to Table 2, the reinforcement structure height Z is set according to the following data ranges: (1) the reinforcement structure height is less than one-third of the height T of the outer wall of the connector body; (2) the reinforcement structure height is between one-third and one-half of the height T of the outer wall of the connector body; (3) the reinforcement structure height is between one-half and three-quarters of the height T of the outer wall of the connector body. For each data range of reinforcement structure height, ten different specific values ​​of reinforcement structure height were selected for the experiment, and the mass of the object corresponding to the maximum push-pull force that the connector of the connecting component can withstand was recorded. The unit of reinforcement structure height Z in Table 2 is millimeters, and the unit of the mass of the object corresponding to the push-pull force is kilograms. As shown in Table 2, when the height Z of the reinforcing structure is less than one-third of the height T of the outer wall of the connector body, the average mass of the object corresponding to the maximum push-pull force that the connector can withstand is 8.929 kg. When the height Z of the reinforcing structure is between one-third and one-half of the height T of the outer wall of the connector body, the average mass of the object corresponding to the maximum push-pull force that the connector can withstand is 10.558 kg. When the height Z of the reinforcing structure is greater than between one-half and three-quarters of the height T of the outer wall of the connector body, the average mass of the object corresponding to the maximum push-pull force that the connector can withstand is 12.604 kg. Therefore, a higher reinforcing structure height is beneficial for enhancing the connection strength between the connector and the connecting plate. Thus, in some embodiments, provided the height of the reinforcing structure is less than the height of the outer wall of the connector body, the height of the reinforcing structure is greater than or equal to half the height of the outer wall of the connector body. In another embodiment, the height of the reinforcing structure is greater than or equal to three-quarters of the height of the outer wall of the connector body.

[0042] According to another embodiment of this application, the reinforcing structure includes a non-Newtonian fluid adhesive layer. The non-Newtonian fluid adhesive is a non-Newtonian fluid thickener whose viscosity increases with shear force. When the connecting assembly is subjected to shear force, the non-Newtonian fluid adhesive can prevent displacement between the surfaces of the connector and the connecting plate, thus exhibiting better impact resistance. When not subjected to external force, the adhesive properties of the non-Newtonian fluid adhesive are similar to those of photosensitive adhesive. When the connector is subjected to external force, the force is transmitted through the connector to the non-Newtonian fluid adhesive in contact with it. The non-Newtonian fluid adhesive rapidly thickens and becomes very hard under external force, thereby quickly increasing the connection strength between the connector and the connecting plate and resisting stronger impact forces. Therefore, the impact resistance of the connecting assembly provided according to this embodiment can be further improved and enhanced.

[0043] According to another embodiment of this application, the pins of the connector in the connection assembly are fixed to the surface of the connection board via pads, the surface including a padless region adjacent to the area where the connector body is located, the padless region including a recessed portion, and the reinforcing structure filling the recessed portion. The following is in conjunction with... Figure 5 and Figure 6 The following example illustrates this embodiment. Figure 5 This is a partial top view of the connection component provided according to this embodiment of the application. Figure 6 for Figure 5 An enlarged schematic diagram of the elliptical region shown. (See attached image.) Figure 5 and Figure 6 As shown, the connector 200 is implemented as a flexible printed circuit board (FPC) in a display device. The connector 200 includes a bonding area 200b for electrical connection to the display module. The circuit board in the display module can be electrically connected to the connector 200 through the bonding area 200b. The pins of the connector 100 are fixed to the surface of the connector 200 via pads. The surface of the connector 200 includes a region where the connector body is located and a padless region NA adjacent to the region where the connector body is located. The padless region NA includes recessed portions G1 and G2, and the reinforcing structure 300 fills the recessed portions G1 and G2. That is, in this embodiment, the recessed portion includes a first recess G1 adjacent to a first end of the connector body and a second recess G1 adjacent to a second end of the connector body, with the first end and the second end facing each other. In some embodiments, an etching technique can be used to form a recess of a certain depth in the padless region NA of the connector 200, such that the recess and its surrounding area form a height difference, or in other words, the surrounding area forms a boss relative to the recessed area. In some embodiments, the height difference is approximately 35 micrometers. In this way, the aforementioned reinforcing structure can be formed by applying liquid adhesive into the groove. The aforementioned boss can prevent the liquid adhesive from overflowing out of the groove, while forming a reinforcing structure in the groove. This reinforcing structure can also enhance the connection strength between the connector and the connecting plate, which is beneficial to enhancing the impact resistance of the connecting components.

[0044] Figure 7 The illustration shows a partial top view of a connection component provided according to another embodiment of this application. Figure 8 It is along Figure 7 The partial cross-sectional view obtained by the dashed lines C1-C2 in the figure is compared with the reference. Figure 5 and Figure 6 The illustrated embodiment is similar; the padless region NA includes a recessed portion. However, in this embodiment, the recessed portion surrounds the connector body, as shown... Figure 7 As shown, the reinforcing structure filling the groove portion can still appear as a ring-shaped band in its orthographic projection onto the connecting plate. However, compared to... Figure 4The cross-sectional views shown are different, in Figure 8 In the partial cross-sectional view of the connecting assembly shown, the reinforcing structure 400 includes a portion of adhesive material embedded within the aforementioned groove and another portion of adhesive material located outside the groove. Therefore, with... Figure 5 and Figure 6 Compared to the embodiment shown, this embodiment can further strengthen the connection between connector 100 and connecting plate 200, and further improve the connector's drop resistance.

[0045] According to an embodiment of this application, the orthographic projection of the connector body on the surface of the connecting plate overlaps the orthographic projection of the pins on the surface. This is for Figure 3 or Figure 7 The embodiment of the connecting component shown is advantageous because the connector pins are covered by the connector body, so the reinforcing structure surrounding the connector body will not come into contact with the connector pins, thereby reducing or avoiding the influence of the reinforcing structure on the connector pins.

[0046] According to another embodiment of this application, the reinforcing structure includes a polyimide layer or a metal layer. That is, in this embodiment, a polyimide layer or a metal layer can be used to replace the aforementioned photosensitive adhesive layer or non-Newtonian fluid adhesive layer. The material of the metal layer includes, but is not limited to, stainless steel. The polyimide layer or metal layer can be attached to the outer wall of the connector body and the surface of the connecting plate by means of an adhesive material. Figure 9 The illustration shows a partial top view of a connection component provided according to another embodiment of this application. Figure 10 It is along Figure 9 The partial cross-sectional view obtained by dashed lines D1-D2 in the figure. The connection assembly includes a connection plate 200 and a connector 100. The connector includes a connector body 100a and pins. The connector body is attached to the surface 200s of the connection plate 200 via the pins. The connector body 100a includes an outer sidewall w extending from the surface 200s in a direction away from the connection plate 200. Figure 9 and Figure 10 In the accompanying drawings, reference numeral 500 indicates a polyimide layer or metal layer attached to the outer wall w and surface 200s. Figure 9 In the illustrated embodiment, a polyimide layer or a metal layer surrounds the connector body. As a reinforcing structure 500 for the polyimide layer or metal layer, it enhances the connection strength between the connector and the connecting plate, improving the connector's drop resistance.

[0047] According to some embodiments of this application, the connecting plate in the connecting assembly includes a flexible printed circuit board. The flexible printed circuit board may include a bonding area, through which a display module in a display device can be bonded to the flexible printed circuit board. A connector attached to the flexible printed circuit board can mate with another connector on a controller used to control the display module. Therefore, using this connecting assembly, an electrical connection between the display module and the controller used to control the display module can be achieved.

[0048] Another embodiment of this application provides a display device that includes a connection component as described in any of the foregoing embodiments. Figure 11 The diagram illustrates the structural block diagram of a display device. For example... Figure 11 As shown, in some embodiments, the display device further includes a display module M and a connection component. The connection component can be implemented as a flexible printed circuit board. The connection component includes a connector 100 and a connection plate 200. The connection plate 200 includes a bonding area 200b, and the connection component is electrically connected to the display module M via the bonding area 200b. The connection component also includes a reinforcing structure Q, which may include the photosensitive adhesive layer, non-Newtonian fluid adhesive layer, polyimide layer, or metal layer described in any of the foregoing embodiments; specific details will not be elaborated further. The reinforcing structure enhances the connection strength between the connector and the connection plate in the flexible printed circuit board, enabling the connector to resist stronger impact and shear forces, thereby improving the connector's drop resistance. Consequently, the stability and reliability of the display device's operating performance are also enhanced.
