DETAILED DESCRIPTION

[0024] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0025] With the widespread application of electronic devices, the output of electronic devices often falls short of demand. Electronic devices can include desktop computers, laptops, mobile phones, tablets and other communication devices with terminal transmission functions. Taking laptops as an example, laptops generally include a display end and a system end. The display end can be understood as the end with a display screen, and the system end is the end with a keyboard and a motherboard system. In actual application, the notebook keyboard adopts a membrane solution. Generally, a keyboard can be shared by many models. The keyboard of each model needs to be connected to the motherboard, specifically to the motherboard connector on the motherboard, so that the keyboard can realize the input function.

[0026] In the existing solution, the motherboard connector on each model's motherboard is set at a different position, resulting in the same film with the same length of flexible printed circuits being unable to meet the connection requirements of motherboard connectors at different positions. The following solutions are generally adopted: First, many new film shapes are developed, and each model is adapted to a film shape, that is, a film shape with a flexible printed circuit of a certain length; second, a film is used after being manually folded many times. In actual application, the former requires a new mold, and the mold opening cost of different film shapes increases; the latter will increase labor costs, and increase too much material number control and operation actions, which will increase control costs accordingly, which is not conducive to high efficiency and cost competition.

[0027] To alleviate the above problems, refer to Figure 1-Figure 3The disclosed embodiments provide an adapter connector assembly 001, a keyboard membrane mechanical adapter device, and an electronic device, which can achieve the effect that a keyboard only needs to open one membrane to be compatible with all models, eliminating the complexity and management cost of multiple membranes; one membrane and a corresponding connector can be adapted to all models, and the space area occupied by the membrane in the shell can be reduced, thereby reducing costs; different flexible cables 80 are customized according to the layout of the motherboard connector positions of different models, and the customization cost of the flexible cable 80 is extremely low, and the required length of the flexible cable 80 is short, which can effectively solve the complexity of manual assembly and improve efficiency.

[0028] The adapter connector assembly 001 provided in the embodiment of the present disclosure is applied to a keyboard membrane mechanical adapter device. Specifically, the adapter connector assembly 001 includes a housing structure 10, a first connecting piece 20 and a second connecting piece 30, wherein the housing structure 10 includes a first mounting position 11 and a second mounting position 12 which is opposite to and separately arranged from the first mounting position 11; illustratively, the first mounting position 11 and the second mounting position 12 are arranged on the top surface and the bottom surface of the housing structure 10 along the thickness direction. Based on this, the first connecting piece 20 is connected to the first mounting position 11, and forms a first plug-in groove 40 with the housing structure 10, and the first plug-in groove 40 can be used for inserting one of the flexible flat cable 80 or the flexible printed circuit 90. Correspondingly, the second connecting piece 30 is connected to the second mounting position 12, and forms a second plug-in groove 50 with the housing structure 10, and the second plug-in groove 50 can be used for inserting the other of the flexible flat cable 80 or the flexible printed circuit 90. Furthermore, in order to realize information exchange between the functional parts in the first plug-in groove 40 and the functional parts in the second plug-in groove 50, the adapter connector assembly 001 of the embodiment of the present disclosure further includes a metal sheet 60, which is arranged between the first mounting position 11 and the second mounting position 12, and extends into the first plug-in groove 40 and the second plug-in groove 50 respectively. Exemplarily, the metal sheet 60 is arranged between the first mounting position 11 and the second mounting position 12 along the thickness direction of the accommodating structure 10. Exemplarily, the metal sheet 60 can be made of any conductive material among silver, copper, gold, aluminum, nano, molybdenum, tungsten, zinc, nickel, iron, platinum, tin, and lead. In this way, the flexible flat cable 80 and the flexible printed circuit 90 located in the first plug-in groove 40 or the second plug-in groove 50 can realize information exchange through the metal sheet 60, thereby realizing the adapter function of the adapter connector assembly 001.

[0029] Exemplarily, the first mounting position 11 is configured as a first accommodating groove on the top surface of the accommodating structure 10, and the first accommodating groove is connected to one side of the first mounting position 11 to form the above-mentioned first plug-in groove 40. The second mounting position 12 is configured as a second accommodating groove on the bottom surface of the accommodating structure 10, and the second accommodating groove is connected to one side of the second mounting position 12 to form the above-mentioned second plug-in groove 50. Among them, there is a first through hole 13 for penetrating the metal sheet 60 between the first accommodating groove and the second accommodating groove.

[0030] Specifically, the metal sheet 60 adopts an angular structure, and the two extended sides can be relatively resiliently pressed, and one side extends out of the first through hole 13 of the first mounting position 11, and the other side extends out of the first through hole 13 of the second mounting position 12. It should be noted that the angle of the metal sheet 60 can be set according to actual application needs.

[0031] For example, along the insertion direction of the flexible flat cable 80 or the flexible printed circuit 90, the height of the metal sheet 60 extending out of the first via hole 13 gradually increases, so as to avoid interference between the flexible flat cable 80 or the flexible printed circuit 90 and the metal sheet 60.

[0032] It should be further pointed out that there are multiple metal sheets 60, one metal sheet 60 is installed correspondingly to one first via hole 13, and there are multiple first via holes 13; each metal sheet 60 is arranged in parallel along the length direction of the first accommodating groove and the second accommodating groove to facilitate multi-line signal connectivity of the corresponding structures of the soft flat cable 80 and the flexible printed circuit 90.

[0033] Specifically, the first connection piece 20 is connected to the accommodating structure 10 by heat-melting, and / or the second connection piece 30 is connected to the accommodating structure 10 by heat-melting. The heat-melting connection method can ensure the connection stability between each connection piece and the accommodating structure 10.

[0034] Further considering the specific hot-melt positions of each connecting piece and the accommodating structure 10, the accommodating structure 10 is provided with a plurality of first hot-melt protrusions 111 on the periphery of the first mounting position 11. For example, each first hot-melt protrusion 111 can be constructed in different shapes, for example, it can be a columnar protrusion structure or a long strip protrusion structure. It should be pointed out that the connection line of each first hot-melt protrusion 111 forms a first U-shape, that is, hot-melting along the U-shaped line can avoid the problem of hot-melting deviation or edge warping. In addition, the accommodating structure 10 is provided with a plurality of second hot-melt protrusions 121 on the periphery of the second mounting position 12. For example, each second hot-melt protrusion 121 can be constructed in different shapes, for example, it can be a columnar protrusion structure or a long strip protrusion structure. It should be pointed out that the connection line of each second hot-melt protrusion 121 forms a second U-shape, that is, hot-melting along the U-shaped line can avoid the problem of hot-melting deviation or edge warping.

[0035] Furthermore, the second U-shaped opening is arranged in the opposite direction to the first U-shaped opening. It should be noted that the first hot melt protrusion 111 and the second hot melt protrusion 121 on the top and bottom surfaces of the accommodating structure 10 in the embodiment of the present disclosure are arranged relatively symmetrically.

[0036] Considering the specific positioning hot-melt method of the first connecting piece 20 and the first hot-melt protrusion 111, the first connecting piece 20 has a first positioning hole group 21 for positioning and assembling with the first hot-melt protrusion 111. Exemplarily, the shape of the first positioning hole group 21 can be a shape corresponding to the structure of the first hot-melt protrusion 111, as long as it can be used for the penetration of each first hot-melt protrusion 111. There should not be a large gap between the first positioning hole group 21 and the first hot-melt protrusion 111, so as to facilitate the hot-melt connection of the first connecting piece 20 with the first hot-melt protrusion 111 in the first positioning hole group 21.

[0037] Considering the specific positioning hot-melt method of the second connecting piece 30 and the second hot-melt protrusion 121, the second connecting piece 30 has a second positioning hole group 31 for positioning and assembling with the second hot-melt protrusion 121. Exemplarily, the shape of the second positioning hole group 31 can be a shape corresponding to the structure of the second hot-melt protrusion 121, as long as it can be used for the penetration of each second hot-melt protrusion 121. There should not be a large gap between the second positioning hole group 31 and the second hot-melt protrusion 121, so as to facilitate the hot-melt connection between the second connecting piece 30 and the second hot-melt protrusion 121 in the second positioning hole group 31.

[0038] Considering the plug-in stability of the soft flat cable 80 and the flexible printed circuit 90 in the adapter connector assembly 001, the adapter connector assembly 001 of the embodiment of the present disclosure also includes a magnetic member 70. The magnetic member 70 can be understood as a structural member that has a magnetic attraction effect on metal materials. For example, the magnetic member 70 can be a magnet. Correspondingly, the accommodating structure 10 has a third mounting position 14, and the third mounting position 14 is used to accommodate the magnetic member 70; the third mounting position 14 is located between the first mounting position 11 and the second mounting position 12, and it can be understood that the third mounting position 14 is separated from the first mounting position 11 and the second mounting position 12. Specifically, the third mounting position 14 is constructed as a third accommodating groove, which is respectively opened on the opposite sides of the accommodating structure 10, which can be the two sides in the length direction. The third mounting position 14 includes two, and the corresponding magnetic member 70 also includes two.

[0039] Considering that the magnetic component 70 can directly apply magnetic attraction to the soft flat cable 80 and the flexible printed circuit 90, the top surface of the accommodating structure 10 has at least one second via 15 arranged through it, and the second via 15 is connected to one of the third accommodating grooves along its own thickness direction. The second via 15 is used to make the magnetism of the magnetic component 70 directly act on the structural component in one of the third accommodating grooves, which may be one of the soft flat cable 80 or the flexible printed circuit 90; the bottom surface of the accommodating structure 10 has at least one third via 16 arranged through it, and the third via 16 is connected to another third accommodating groove along its own thickness direction. The third via 16 is used to make the magnetism of the magnetic component 70 directly act on the structural component in another third accommodating groove, which may be the other of the soft flat cable 80 or the flexible printed circuit 90.

[0040] Exemplarily, the first connecting sheet 20 and the second connecting sheet 30 are made of stainless steel, and can also be magnetically attracted by the magnetic member 70. In addition, there are two magnetic members 70 in the embodiment of the present disclosure, which can facilitate the full fit of the flexible printed circuit 90 and the flexible flat cable 80 of the keyboard membrane with the metal sheet 60, respectively, to ensure full signal connectivity.

[0041] In summary, the combined application of the magnetic member 70 and the hot melt can ensure the connection stability between each connecting member and the accommodating structure 10.

[0042] In addition, the adapter connector assembly 001 of the embodiment of the present disclosure also provides another connection method between each connecting piece and the accommodating structure 10, that is, the first connecting piece 20 is detachably connected to the accommodating structure 10; and / or the second connecting piece 30 is detachably connected to the accommodating structure 10. The detachable connection here can adopt a common mechanical positioning and locking method. For example, screws, bolts or other non-standard structural parts with positioning functions can all be used to achieve the detachable connection between each connecting piece and the accommodating structure 10. It is preferred to use a positioning structure with insulating properties for assembly.

[0043] The disclosed embodiment also provides a keyboard membrane mechanical transfer device, including the above-mentioned transfer connector assembly 001, and also including: a keyboard membrane, a flexible flat cable 80, a flexible printed circuit 90 and a motherboard connector; one end of the flexible flat cable 80 is detachably plugged into the first plug-in groove 40 and electrically connected to the metal sheet 60, and the other end of the flexible flat cable 80 is electrically connected to the motherboard connector; the flexible printed circuit 90 extends from the keyboard membrane, and one end of the plug of the flexible printed circuit 90 is detachably plugged into the second plug-in groove 50 and electrically connected to the metal sheet 60. In this way, the full effect of the signing transfer structure assembly can be achieved. In addition, the transfer connector assembly 001 can adapt to the connection of the flexible printed circuit 90 extending from any film, and the connection with the motherboard connector can be achieved through a simple flip of the flexible flat cable 80. In addition, the cost of the flexible flat cable 80 is low, saving production costs. At the same time, the common application of the flexible flat cable 80 and the transfer connector assembly 001 can save the installation space occupied in the housing.

[0044] The disclosed embodiment also provides an electronic device, including the keyboard membrane mechanical adapter device, and also including a display terminal and a system terminal connected to the display terminal in communication, the system terminal including an upper shell with a keyboard, a lower shell for supporting the keyboard, and a mainboard circuit board, the keyboard membrane mechanical adapter device is installed between the upper shell and the lower shell, the keyboard membrane is arranged on the bottom surface of the keyboard, the mainboard connector is connected to the mainboard circuit board, the flexible flat cable 80 and the flexible printed circuit 90 at least partially occupy the accommodation space between the upper shell and the lower shell, and reserve a reserve space. In this way, the reserved reserve space can be used to realize other functions of the notebook computer.
