[0027] The present application provides a wiring structure, which can well meet the demand for the development of lightweight and thin electronic devices.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] See also Figure 1~Figure 4 , Embodiment 1 of the present application provides a wiring structure for realizing electrical connection between a mainboard 7 and a target component 1, the wiring structure comprising a flat cable 4 and a connector 6, wherein the flat cable 4 is arranged on the largest surface of the target component 1, and the flat cable 4 has a first end bent from the edge of the largest surface toward the side surface of the target component 1 adjacent to the largest surface, the connector 6 is located on the side surface of the target component 1, and has an elastic terminal 61 abutting against a gold finger 41 at the first end of the flat cable 4, and the abutting direction of the elastic terminal 61 and the gold finger 41 meets the parallel condition with the board surface of the mainboard 7. It should be understood that the largest surface of the target component 1 refers to the surface with the largest area of ​​the target component 1, that is, the surface seen from the perspective along the thickness direction of the target component 1, for example, in Figure 1 In the exemplary application scenario, the target component 1 is a fan, and the largest surface of the fan is the surface that satisfies the perpendicular condition to the axis of the fan, that is, Figure 1The surface where the flat cable 4 is arranged. The flat cable 4 has a relatively thin thickness, so the arrangement of the flat cable 4 against the largest surface of the target component 1 can minimize the space occupied in the thickness direction. At the same time, the connector 6 is arranged on the side of the target component 1, which also minimizes the space occupied in the thickness direction. In the thin and light design of electronic equipment, the largest surface of the target component 1 is usually set to meet the parallel condition with the board surface of the main board 7. Therefore, the connector 6 in the present application has an elastic terminal 61 that abuts against the gold finger 41 at the first end of the flat cable 4, and the abutting direction of the elastic terminal 61 and the gold finger 41 meets the parallel condition with the board surface of the main board 7. On the one hand, it is more convenient for the automated assembly of the wiring structure, and on the other hand, it can well meet the thin and light design requirements of electronic equipment.

[0030] In specific practical applications, there are many options for the type of target component 1. For example, the target component 1 may be a fan, a speaker, etc. In a specific application scenario, Figure 1 As shown, the target component 1 is a cooling fan for dissipating heat for a heat-generating component 3 (such as a CPU). The heat generated by the heat-generating component 3 is transferred to the target component 1 through the heat transfer element 2, and then the wind generated by the target component 1 takes away the heat, thereby dissipating the heat for the heat-generating component 3.

[0031] like Figure 2~Figure 4 As shown, in a preferred embodiment, the connector 6 is located at the first edge of the mainboard 7 and is fixedly connected to the mainboard 7, and the side of the target component 1 is arranged toward the first edge of the mainboard 7. The connector 6 is fixedly connected to the mainboard 7, and the assembly with the flat cable 4 is realized as the mainboard 7 and the target component 1 are assembled, which has a high assembly efficiency and is more conducive to the realization of automated assembly. The connector 6 is located at the first edge of the mainboard 7, and the side of the target component 1 is arranged toward the first edge of the mainboard 7, so that the target component 1 and the mainboard 7 are arranged in the same plane as much as possible, that is, the target component 1 and the mainboard 7 are avoided from being stacked in the thickness direction as much as possible, which is more conducive to the realization of thin and light electronic equipment.

[0032] See also Figure 4 On the basis of the side of the target component 1 facing the first edge of the main board 7, it is further preferred that the target component 1 has a support platform 11 protruding from the side, and the support platform 11 is provided with a positioning column 5 for assembly and connection with the main board 7, and the axis of the positioning column 5 meets the parallel condition with the side of the target component 1. The positioning column 5 is used for positioning and connecting the main board 7 with the target component 1, and the main board 7 is provided with a connection hole that cooperates with the positioning column 5, for example, Figure 3 In the exemplary structure, the main board 7 is provided with two connecting holes, one small and one large, namely, a first connecting hole 71 and a second connecting hole 72. Figure 4In the exemplary structure, two positioning posts 5 are provided, one thin and one thick, wherein the thicker positioning post 5 is provided with a positioning hole 8, which can be used to realize the positioning and installation of the target component 1 on the housing of the electronic device, or can be used to realize the positioning and installation of other components in the electronic device except the mainboard 7 and the target component 1. Figure 2 It is easy to understand that when assembling the main board 7 and the target component 1, the main board 7 and the target component 1 move relative to each other along the thickness direction of the target component 1, the first connection hole 71 is sleeved onto the thinner positioning column 5, and the second connection hole 72 is sleeved onto the thicker positioning column 5. Since a part of the elastic terminal 61 protrudes from the side of the connector 6 facing the target component 1, during the process of the main board 7 moving relative to the target component 1 for assembly, the elastic terminal 61 slides on the gold finger 41 of the flat cable 4 and finally abuts. It should be noted that the elastic terminal 61 is pre-connected with the circuit on the main board 7 when the connector 6 is fixedly connected to the main board 7, so the electrical connection between the main board 7 and the target component 1 is achieved after the elastic terminal 61 abuts against the gold finger 41 of the flat cable 4.

[0033] like Figure 4 As shown, the first end of the cable 4 is bent and arranged against the side of the target component 1. In order to keep the first end of the cable 4 firmly fixed to the target component 1, in this embodiment, the target component 1 has a limiting boss 10 protruding from the side, and the two limiting bosses 10 arranged opposite to each other respectively have stoppers extending toward each other, and a space for accommodating the side of the cable 4 is formed between the stoppers and the side of the target component 1. The first end of the cable 4 is bent from the maximum surface edge of the target component 1 toward the side of the target component 1 and then extends between the two limiting bosses 10, and the edge of the cable 4 is clamped by the stopper of the limiting boss 10, so that the first end of the cable 4 is firmly kept relatively motionless with the target component 1.

[0034] See also Figure 2 and Figure 4 After the connector 6 and the flat cable 4 form the wiring structure of the present application, the gold finger 41 at the first end of the flat cable 4 is subjected to the abutting force from the elastic terminal 61 of the connector 6 toward the side of the target component 1. The first end of the flat cable 4 near the gold finger 41 is relatively soft. In order to avoid the abutting force of the elastic terminal 61 from damaging the first end of the flat cable 4, a support plate 9 can be arranged between the first end of the flat cable 4 and the side of the target component 1. The support plate 9 is arranged against the side of the target component 1, and the flat cable 4 is abutted against the board surface of the support plate 9. The support plate 9 has a certain strength and can play a good supporting role.

[0035] In other embodiments, the connector 6 may not be pre-fixedly connected to the mainboard 7. Figure 5 and Figure 6In the second embodiment of the present application, the wiring structure includes a card holder, which is fixed to the side of the target component 1, and the card holder has a card slot for installing the connector 6, and the connector 6 is detachably connected to the card holder. It should be noted that Figure 5 The main board 7 is omitted and not shown. The board surface of the main board 7 has a connection point (ie, a conductive terminal) that abuts against the elastic terminal 61. After the main board 7 and the target component 1 are installed in place, the connection point of the main board 7 abuts against the elastic terminal 61. Figure 5 As shown, the end of the elastic terminal 61 away from the flat cable 4 has a downward abutting portion for abutting against the wiring point of the mainboard 7, that is, in this embodiment, the mainboard 7 is located below the elastic terminal 61 in the thickness direction of the target component 1. In other embodiments, the mainboard 7 can also be arranged to be located above the elastic terminal 61 in the thickness direction of the target component 1, for example Figure 7 In the third embodiment of the present application, the side of the mainboard 7 having the connection point is arranged downward to abut against the elastic terminal 61 of the connector 6.

[0036] The card holder arranged on the side of the target component 1 is used for detachable connection with the connector 6. The structural form of the card holder can be selected in a variety of ways. In a preferred embodiment, the card holder includes two hooks 12 arranged opposite to each other, and the space between the two hooks 12 forms a card slot. In the process of placing the connector 6 between the two hooks 12, the hook 12 is squeezed by the connector 6 and elastically deformed. When the connector 6 is in place, the two hooks 12 clamp the connector 6. In this structure, the connector 6 and the card holder can be quickly disassembled and assembled, which is conducive to improving assembly efficiency. Moreover, the assembly method is simple to operate and easy to realize mechanical automation.

[0037] See also Figure 6 In a preferred embodiment, the connector 6 has a slot, and the elastic terminal 61 has a first elastic end 611 located in the slot and a second elastic end located outside the connector 6. The first elastic end 611 abuts against the gold finger 41 of the flat cable 4, and the second elastic end abuts against the conductive terminal located on the board surface of the mainboard 7. In a natural state (i.e., when the flat cable 4 is not inserted into the slot of the connector 6), the gap between the first elastic end 611 of the elastic terminal 61 and the inner wall of the slot is smaller than the thickness of the flat cable 4. After the first end of the flat cable 4 is inserted into the slot of the connector 6, the first end of the flat cable 4 is clamped between the first elastic end 611 of the elastic terminal 61 and the inner wall of the slot, so that the first elastic end 611 abuts against the gold finger 41 of the flat cable 4. Figure 6 As shown, the above-mentioned inner wall of the slot is preferably set to a side of the inner surface of the slot away from the target component 1, so that the bending degree formed when the first end of the cable 4 is bent from the maximum surface edge of the target component 1 to the side of the target component 1 is small, and the formation of a right-angle bend in the local area of ​​the cable 4 is avoided as much as possible.

[0038] The position of the conductive terminal of the mainboard 7 abutting against the elastic terminal 61 of the connector 6 on the mainboard 7 may affect the layout structure of the mainboard 7 and the target component 1. In a preferred embodiment, the side of the target component 1 is arranged toward the first edge of the mainboard 7, and the conductive terminal is located near the first edge. In this wiring structure, the mainboard 7 is arranged on one side of the target component 1, which avoids the stacking of the mainboard 7 and the target component 1, which is beneficial to reducing the overall thickness of the electronic device.

[0039] like Figure 6 As shown, in this embodiment, the side wall of the slot is provided with a receiving groove corresponding to the elastic terminal 61, and the part of the elastic terminal 61 close to the first elastic end 611 is fixed in the receiving groove. In this structure, the spacing between the elastic terminals 61 is not adjustable, and the elastic terminals 61 are usually evenly arranged along the width direction of the cable 4, that is, the elastic terminals 61 are distributed at equal intervals. In other embodiments, in order to improve the adaptability of the connector 6 to different cables 4, the elastic terminals 61 can be set to have adjustable spacing. For example, in a specific embodiment, the bottom surface of the slot is provided with a long hole connected to the outside of the connector 6, and the length direction of the long hole meets the parallel condition with the arrangement direction of the elastic terminal 61. All elastic terminals 61 are inserted into the long hole and can be adjusted along the length direction of the long hole. It should be noted that after the elastic terminal 61 is adjusted, it can be fixed at the adjusted position, so as not to affect the normal use of the connector 6. Specifically, an insulating pressing plate can be provided at the bottom of the connector 6, and all the elastic terminals 61 pass through between the bottom surface of the connector 6 and the pressing plate, and the pressing plate can switch between two states of pressing the elastic terminals 61 and releasing the elastic terminals 61. When it is necessary to adjust the spacing of the elastic terminals 61, the pressing plate is first switched to a state of releasing the elastic terminals 61 so that the elastic terminals 61 can move along the arrangement direction, and after the elastic terminals 61 are adjusted in position, the pressing plate is switched to a state of pressing the elastic terminals 61. The pressing plate and the bottom of the connector 6 can be connected by, for example, bolts, buckles, etc., as long as the pressing plate can be switched between two states of pressing the elastic terminals 61 and releasing the elastic terminals 61.

[0040] In the above embodiments, the flat cable 4 is preferably configured as an FFC flat cable, so as to reduce costs and realize more convenient automated assembly with the connector 6. Of course, the flat cable 4 can also be configured as other types, such as an FPC flat cable. In order to achieve the physical connection and fixation between the target component 1 and the motherboard 7, a connecting portion 13 can be provided on the side of the target component 1, such as Figure 5 As shown, the connection portion 13 may be provided with a mounting hole for mounting bolts, and the main board 7 is fixedly connected to the connection portion 13 of the target component 1 by bolts. The connection portion 13 is usually arranged near the connector 6, so as to ensure that the conductive terminal of the main board 7 and the elastic terminal 61 of the connector 6 are more securely abutted.

[0041] The present application also provides an electronic device, which includes a mainboard 7 and functional components, and the mainboard 7 and the functional components are electrically connected through the wiring structure disclosed in the above embodiment. Since the wiring structure disclosed in the above embodiment has the above technical effects, the electronic device having the wiring structure also has the above technical effects, which will not be repeated here. Specifically, the electronic device can be a laptop computer, a tablet computer, a mobile phone, etc., and the functional components can be a fan, a speaker, etc.

The wiring structure, the overall and partial structures of the electronic device can be obtained by combining the structures of the above multiple parts.
