Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1 to 7, the present invention provides an FPC fixing structure. The FPC fixing structure includes a mounting seat 101 and an FPC102, the mounting seat 101 having a mounting groove 103, one end of the FPC102 being inserted into the mounting groove 103, a wall surface of the mounting groove 103 being capable of sandwiching the FPC102 in a thickness direction of the FPC102, thereby fixing an end portion of the FPC 102. Correspondingly, the invention also provides a FPC102 fixing method, which comprises the following steps: the end of the FPC102 is inserted into the mounting groove 103 so that the wall surface of the mounting groove 103 sandwiches the FPC102 in the thickness direction of the FPC 102.
According to the FPC fixing structure, the FPC102 is clamped along the thickness direction of the FPC102 by utilizing the wall surface of the mounting groove 103 so as to fix the FPC102, when an assembler assembles the FPC102 and the mounting seat 101, the FPC102 only needs to be inserted into the mounting groove 103 until the wall surface of the mounting groove 103 clamps the FPC102, the FPC fixing structure is high in assembling convenience, and the FPC102 mounting efficiency is improved.
Specifically, referring to fig. 1 to 5, in some embodiments, the mounting groove 103 has two through holes 300 that are communicated with each other, the two through holes 300 are a first through hole 301 and a second through hole 302, respectively, the first through hole 301 and the second through hole 302 are both disposed on an outer surface of the mounting seat 101, and the first through hole 301 and the second through hole 302 are respectively located on two adjacent sides of the mounting seat 101. In the specific directions shown in fig. 1 to 3, the upper side wall surface and the lower side wall surface of the mounting groove 103 jointly clamp the FPC 102; referring to fig. 1, after the FPC102 is fixed, the FPC102 is inserted into the second insertion hole 302. In addition, the first through hole 301 is set to be large enough, and the first through hole 301 can be passed by the FPC102, so that the FPC102 can enter the mounting groove 103. With reference to fig. 1 and 2, in this arrangement, FPC102 is mounted in substantially the following manner: the relative position and relative orientation between the FPC102 and the mounting seat 101 are substantially adjusted to the state shown in fig. 2, and then the assembler holds the FPC102 by hand to move the FPC102 from right to left, so that the FPC102 passes through the first penetrating opening 301; then, the FPC102 will move along the second through hole 302 until the mounting base 101 clamps the FPC 102.
Referring to fig. 7, in other embodiments, the mounting groove 103 has only one through hole 300, and similarly, the through hole 300 is disposed on the outer surface of the mounting seat 101, and the upper side wall surface and the lower side wall surface of the mounting groove 103 jointly clamp the FPC 102. In this arrangement, the FPC102 is mounted substantially as follows: the end of the FPC102 is faced to the through-hole 300, and then the FPC102 is moved so that the FPC102 is inserted into the mounting groove 103 from the through-hole 300.
It should be noted that, since the FPC102 can be bent or bended, the thickness direction of the FPC102 mentioned in the present invention is based on the thickness direction of the substrate 201 at the section where the FPC102 is located in the mounting groove 103.
In order to improve the ease of operation of inserting the FPC102 into the mounting groove 103, a reinforcing plate 202 may be provided in the FPC102 to increase the strength and thickness of the end of the FPC102 inserted into the mounting groove 103. Specifically, referring to fig. 2, the FPC102 includes a substrate 201 and a reinforcing plate 202, the substrate 201 has flexibility, the reinforcing plate 202 is attached to the surface of the substrate 201, and the reinforcing plate 202 is disposed at one end of the substrate 201 accommodated in the mounting groove 103. The reinforcing plate 202 is also accommodated in the mounting groove 103 and is supported by the wall surface of the mounting groove 103; if the reinforcing plate 202 is not provided, the wall surface of the mounting groove 103 directly contacts and holds the substrate 201.
The reinforcing plate 202 may be a steel sheet, and the material of the reinforcing plate 202 may also be a commonly used reinforcing material such as PI (polyimide), FR-4(FR-4 grade glass fiber epoxy resin), and the like. The shape of the stiffener 202 needs to be properly set to avoid the circuit and the electronic components on the substrate 201. The reinforcing plate 202 may be attached to one surface of the substrate 201, or the reinforcing plates 202 may be attached to both sides of the substrate 201.
Compared with the FPC102 without the reinforcing plate 202, the thickness and hardness of the end portion of the FPC102 with the reinforcing plate 202 are larger, the end portion of the FPC102 is less prone to collapse when an assembler holds the FPC102, and the operation of inserting the FPC102 with the reinforcing plate 202 into the installation groove 103 is more convenient. In addition, the thickness of the end of the FPC102 disposed in the mounting groove 103 is large, and accordingly, the height of the mounting groove 103 may also be set large, so as to prevent the mounting groove 103 from being too small in height to cause too high processing difficulty of the mounting seat 101 and difficulty in inserting the FPC102 into the mounting groove 103.
In order to improve the ease of assembly of the FPC102, a positioning body 105 may be provided in the FPC102, and a positioning groove 104 may be provided in the mount 101.
Specifically, referring to fig. 1 to 3, in the case where the mounting groove 103 has a first through hole 301 and a second through hole 302, the mounting seat 101 has a positioning groove 104, and the bottom of the positioning groove 104 and the top of the mounting groove 103 communicate with each other. One end of the positioning slot 104 has a positioning inlet 303, the positioning inlet 303 is disposed on the outer surface of the mounting seat 101, and the positioning inlet 303 and the first penetrating opening 301 are communicated with each other and located on the same side of the mounting seat 101. Alternatively, referring to fig. 7, the mounting groove 103 has only one through opening 300, and the positioning inlet 303 and the through opening 300 are communicated with each other and located on the same side of the mounting seat 101.
Referring to fig. 2, the FPC102 includes a substrate 201 and a positioning body 105, the substrate 201 has flexibility, a surface of the substrate 201 may be printed with a circuit, and the positioning body 105 may be directly connected to the substrate 201 and protrude with respect to the surface of the substrate 201. The positioning inlet 303 is capable of allowing the positioning body 105 to pass through, the positioning body 105 is accommodated in the positioning slot 104, and the substrate 201 is located in the mounting groove 103. The wall surface of the positioning groove 104 can abut against the positioning body 105, so that the mounting seat 101 and the FPC102 are positioned. Taking fig. 1 and 2 as an example, the wall surface of the positioning slot 104 can restrict the movement of the positioning body 105 along the front-back direction.
Referring to fig. 2 or 7, in the case where the positioning body 105 and the positioning groove 104 are provided, the positioning body 105 slides into the positioning groove 104 while the base plate 201 slides into the mounting groove 103 (or the base plate 201 and the reinforcing plate 202 slide together into the mounting groove 103). Therefore, the positioning matching between the positioning groove 104 and the positioning body 105 can ensure the position stability of the FPC102 after the FPC102 is installed, and can guide the movement of the FPC102 in the movement process of the FPC102, thereby facilitating the installation of the FPC 102.
The positioning body 105 can be adjusted as appropriate, the positioning body 105 in fig. 2 and 7 is provided in a cubic shape, and the positioning body 105 may be provided in other polygonal column shapes, cylindrical shapes, spherical shapes, and the like. In addition, the positioning body 105 mainly functions as positioning and guiding, and does not need to be connected to a circuit on the FPC 102. If the FPC102 includes the substrate 201, the reinforcing plate 202, and the positioning body 105, the positioning body 105 may be directly attached to a surface of the reinforcing plate 202 opposite to the substrate 201 and may protrude from the reinforcing plate 202 and the substrate 201.
In addition, referring to fig. 3 and 7, the mounting groove 103 further has an avoiding opening 304, the avoiding opening 304 is also disposed on the outer surface of the mounting seat 101, and the avoiding opening 304 can prevent the mounting seat 101 from shielding some electronic components of the FPC102, so as to prevent the mounting seat 101 from affecting the normal operation of the electronic components. For example, one end of the FPC102 accommodated in the mounting groove 103 has a hall switch, and the hall switch may be disposed below the avoiding opening 304, so as to prevent the mounting seat 101 from shielding the hall switch and affecting the accuracy thereof; or, the end of the FPC102 accommodated in the mounting groove 103 has an LED light emitting chip, and the light emitting chip may be disposed below the avoiding opening 304 so that light of the light emitting chip is emitted.
In order to reduce the resistance of insertion of the FPC102 into the mounting groove 103 for mounting of the FPC102, the height of the mounting groove 103 may be set to be gradually reduced.
Specifically, referring to fig. 1 and 6, in some embodiments, the side surface of the mount 101 provided with the first through-hole 301 starts fromThe surface 601, the wall surface of the mounting groove 103 far away from the first penetrating port 301 is a limiting surface 602, and the height of the mounting groove 103 is gradually reduced from the starting surface 601 to the limiting surface 602. The dimension of the mounting groove 103 in the thickness direction of the FPC102 is the height of the mounting groove 103. With reference to the specific direction of fig. 6, the dimension of the mounting groove 103 in the vertical direction is the height of the mounting groove 103, and the height of the right end of the mounting groove 103 is L1The height of the left end of the mounting groove 103 is L2，L1>L2And the height of the mounting groove 103 is gradually reduced from right to left.
Similarly, referring to fig. 7, in other embodiments, in the case that only one through hole 300 is provided on the surface of the mounting seat 101, a side surface of the mounting seat 101 on which the through hole 300 is provided is taken as a starting surface 601, and an end wall surface of the mounting groove 103 far away from the through hole 300 is taken as a limiting surface 602; the height of the installation groove 103 gradually decreases from the starting surface 601 to the limiting surface 602. Referring to the specific direction of fig. 7, the dimension of the mounting groove 103 in the up-down direction is the height of the mounting groove 103, the right side surface of the mounting seat 101 is the starting surface 601, the left end of the mounting groove 103 is avoided to be the limiting surface 602 (the limiting surface 602 is not specifically shown in fig. 7), and the height of the mounting groove 103 gradually decreases from right to left.
That is, the height of the mounting groove 103 gradually decreases in the direction in which the FPC102 slides into the mounting groove 103. In this arrangement, the mounting groove 103 is higher near the first through opening 301, which facilitates the entry of the FPC102 into the mounting groove 103; meanwhile, when the FPC102 just enters the mounting groove 103, the upper side wall surface and the lower side wall surface of the mounting groove 103 have large gaps with the FPC102, and resistance to the movement of the FPC102 is small, so that the FPC102 can be moved quickly. When the FPC102 moves to the vicinity of the stopper surface 602, the height of the mounting groove 103 where the FPC102 is located becomes relatively small, and the upper side wall surface and the lower side wall surface of the mounting groove 103 clamp the FPC102, thereby fixing the position of the end of the FPC 102.
Referring to fig. 8 to 11, the present invention also provides an earphone charging box 801, and the earphone charging box 801 includes the FPC fixing structure in the above-described embodiment.

The mounting base 101 may be snapped to the cassette 803. Referring to fig. 1 and 10, the mounting base 101 has a clamping hole 106, the box body 803 has a clamping body 905, and the clamping body 905 can be clamped into the clamping hole 106, so that clamping between the mounting base 101 and the box body 803 is realized. Further, mount 101 may be bonded to case 803, and mount 101 may be injection-molded integrally with case 803. Here, the connection between the mounting base 101 and the box 803 is not always illustrated.
The battery 1103 and the main board 902 are electrically connected by a wire, and the FPC102 is also electrically connected to the main board 902. The main board 902 has a first connector 904 and a second connector 903, the first connector 904 may be configured as a pogo pin, and the second connector 903 may be configured as a type-c interface (a specific structure is not shown in fig. 9); of course, the form of the first connector 904 and the second connector 903 is not limited to the above form, and may be modified to other connectors that can be used to realize electrical connection.

The first connector 904 is used to make contact with the headset so that the battery 1103 charges the headset; the second connector 903 is used for plugging with an external cable so that the external power supply charges the battery 1103. The circuit structure of the main board 902 for implementing the charging function is well known in the art and will not be described in detail herein.
As described above, in some embodiments, the end of the FPC102 disposed in the mounting groove 103 may have a hall switch, and accordingly the upper cover 802 of the earphone charging box 801 may be connected with a magnet; the main board 902 may receive signals of hall switches on the FPC102, so as to determine whether the earphone charging box 801 is opened according to the signals of the hall switches, thereby performing corresponding actions.
