Description

Technical Field

[0001] The present application relates to the technical field of pressure-maintaining fixtures, and in particular to a pressure-maintaining fixture for an earphone tail plug. Background Art

[0002] Currently, earphones are primarily categorized into two types: bean-shaped and rod-shaped. Tubular earphones are widely used in the disassembly of rod-shaped earphones because their mid-shell is relatively intact. A tight connection between the mid-shell and the tail plug is crucial to ensuring the integrity of the earphones. A common method currently involves applying hot melt glue to the ear tube in the mid-shell, inserting the tail plug into the mid-shell, and securing the tail plug retaining wall with the hot melt glue. Because hot melt glue takes time to cure, it's necessary to manually wrap a rubber band around the mid-shell, ear bag, and tail plug to maintain pressure while the glue solidifies.

[0003] However, this method of using rubber bands to fix the tail plug relies on manual labor. During the specific operation, the rubber band needs to be stretched first, and then wrapped to fix the earphone ear bag and the tail plug, which has low production efficiency. At the same time, the fixing position of the tail plug is small, and the rubber band is easy to slip and loosen. Moreover, the entire earphone assembly after being fixed with the rubber band has an inconsistent shape, and it is not easy to make a container for placement. When the earphones are placed together and contact each other, there is a risk of scratching the appearance of the earphones. Utility Model Content

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0025] In the description of the embodiments of the present application, "multiple" and "several" mean more than two (including two), unless otherwise clearly and specifically defined.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] According to some embodiments of the present application, referring to Figure 1 As shown, Figure 1The figure is a schematic structural diagram of the headphone tail plug pressure-maintaining jig according to an embodiment of the present application. The headphone tail plug pressure-maintaining jig according to an embodiment of the present application comprises: a jig base 1, a jig lower die 2, and a tail clip 4. The jig lower die 2 is disposed on the jig base 1 and has a limit assembly for limiting the position of the headphone 3. The tail clip 4 has an abutment portion 41 that can drive the abutment portion 41 to abut the tail plug 31 of the headphone 3 to secure the headphone 3 within the limit assembly. The abutment portion 41 also applies a preset pressure to the headphone 3.

[0028] After the tail plug 31 of the earphone 3 and the middle shell 32 of the earphone 3 are assembled by glue dispensing, they are placed in the lower mold 2 of the jig and fixed by the limit assembly. The tail clip 4 is pressed against the tail plug 31 to form pressure to ensure that there is no gap between the tail plug 31 and the middle shell 32 of the earphone. The pressure is maintained and allowed to stand for 30 minutes to ensure that the hot melt adhesive is effectively combined with the middle shell and the tail plug of the earphone. After the pressure is released, there is no gap between the tail plug and it will not fall off, which reduces the workers' fatigue caused by pulling the rubber band for a long time and improves the assembly efficiency.

[0029] According to some embodiments of the present application, reference Figure 1 As shown, the limiting assembly includes a receiving groove 21, which includes a middle shell groove 211 and an ear bag groove 212. The middle shell groove 211 is arranged at one end of the receiving groove 21 close to the tail clip 4 and is used to accommodate the middle shell 32 of the earphone 3. The ear bag groove 212 is arranged at one end of the receiving groove 21 away from the tail clip 4 and is used to accommodate the ear bag 33 of the earphone 3.

[0030] Specifically, the cross-sectional area of ​​the ear package groove 212 is larger than the cross-sectional area of ​​the middle shell groove 211 .

[0031] Dividing the accommodating groove 21 into the middle shell groove 211 and the ear bag groove 212 can make the shape of the accommodating groove 21 more matched with the outline of the earphone 3. When the earphone 3 is placed in the accommodating groove 21, it is not easy to shake, which is conducive to the subsequent pressure maintenance of the tail plug 31 of the earphone 3.

[0032] Of course, in other embodiments, the limiting component may also be in other forms, such as a clamp, as long as it can fix the earphone 3.

[0033] According to some embodiments of the present application, reference Figure 2 As shown, Figure 2 The tail clip 4 includes an abutment portion 41, a handle 42, a guide post 43, and a guide sleeve 44. The guide post 43 is connected to the abutment portion 41, and the handle 42 can drive the guide post 43 to slide relative to the guide sleeve 44, thereby driving the abutment portion 41 to abut the tail plug 31.

[0034] In some embodiments, the abutting portion 41 is made of elastic material.

[0035] By using an elastic material for the abutting portion 41, it is possible to ensure that the abutting portion 41 does not cause hard damage to the tail plug 31 of the earphone 3 while generating pressure on the tail plug 31 of the earphone 3; and the elastic material can be used to have good deformation ability to further generate pressure on the tail plug 31 of the earphone 3, thereby enhancing the pressure-maintaining effect.

[0036] Different models of earphones 3 usually have different sizes. By rotating the handle 42 to drive the guide column 43 to slide relative to the guide sleeve 44, the extended length of the guide column 43 relative to the guide sleeve 44 can be adjusted to adapt to maintaining pressure on earphones 3 of different lengths, making the fixture more applicable.

[0037] According to some embodiments of the present application, reference Figure 2 The tail clip 4 also includes a tail clip base 45 fixedly connected to the fixture base 1, and the handle 42 is installed on the tail clip base 45.

[0038] Specifically, a fixing hole 451 is provided on the tail clip base 45, and a fixing member is passed through the fixing hole 451 to fix the tail clip base 45 on the base 1. The fixing member here can be a bolt.

[0039] The tail clip base 45 is fixedly connected to the base 1 to enhance the stability of the fixture.

[0040] According to some embodiments of the present application, reference Figure 2 A limiting portion 46 is provided at one end of the guide post 43 away from the guide sleeve 44 . The limiting portion 46 is used to abut against the end of the guide sleeve 44 when the guide post 43 slides relative to the guide sleeve 44 toward the handle 42 to limit the guide post 43 .

[0041] Specifically, if the cross sections of the guide pillar 43 and the limiting portion 46 are both circular, the cross section diameter of the limiting portion 46 is larger than the cross section diameter of the guide pillar 43 .

[0042] Because when the guide post 43 slides relative to the guide sleeve 44, it may completely slide into the guide sleeve 44, which will make the fixture function ineffective. A limit portion is provided at the end of the guide post 43 away from the guide sleeve 44 to prevent the guide post 43 from completely sliding into the guide sleeve 44 when the guide post 43 slides relative to the guide sleeve 44 toward the handle 42.

[0043] In other embodiments, reference Figure 2 As shown, the handle 42 includes a hand-held portion 421 and an arc-shaped connecting member 422. One end of the arc-shaped connecting member 422 is hinged to the guide column 43, and the other end is hinged to the hand-held portion 421. One end of the hand-held portion 421 is hinged to the tail clip base 45. When the hand-held portion 421 rotates, the arc-shaped connecting member 422 is driven to move, and the arc-shaped connecting member 422 drives the guide column 43 to slide relative to the guide sleeve 44.

[0044] Specifically, one end of the arcuate connector 422 is hinged to the guide post 43 at a first hinge point 423, the other end of the arcuate connector 422 is hinged to the handle 421 at a second hinge point 424, and the handle 421 is hinged to the tail clip base 45 at a third hinge point 425. The second hinge point 424 is located between the first hinge point 423 and the third hinge point 425.

[0045] The operator rotates the handheld part 421. Since the handheld part 421 and the arc-shaped connecting part 422 are hinged at the second hinge point 424, and the arc-shaped connecting part 422 is also hinged to the guide column 43 at the first hinge point 423, when the handheld part 421 is rotated, the arc-shaped connecting part 422 can drive the guide column 43 to move forward and backward, that is, by rotating the direction of the handheld part 421, the guide column 43 can be inserted into the guide sleeve 44, which is convenient for adjusting the extension length of the guide column 43.

[0046] In some embodiments, the axis of the abutting portion 41 of the tail clip 4 is in the same plane as the axis of the tail plug 31. Preferably, the axis of the abutting portion 41 of the tail clip 4 coincides with the axis of the limiting assembly.

[0047] Specifically, "the axis of the abutting portion 41 of the tail clip 4 and the axis of the limiting assembly are in the same plane" is to make the axis of the guide column 43 and the axis of the middle shell 32 of the earphone 3 in the same plane, so that the abutting portion 41 of the tail clip 4 and the tail plug 31 of the earphone 3 can abut against each other and generate pressure, which is used to maintain the pressure of the tail plug 31 of the earphone.

[0048] It is worth noting that in order to make full use of the pressure generated by the abutment 41 on the tail plug 31 of the earphone 3, the axis of the abutment 41 of the tail clip 4 is preferably coincident with the axis of the tail plug 31, so that the pressure generated by the abutment 41 on the tail plug 31 can be fully used to maintain the pressure of the earphone tail plug.

[0049] like Figure 1 As shown, in some embodiments, there may be multiple tail clips 4 , and each tail clip 4 corresponds to a limiting assembly.

[0050] Specifically, multiple tail clips 4 are spaced apart on the tail clip base 45 along a direction perpendicular to the axis of the abutting portion 41 of the tail clip 4; similarly, the limiting components are spaced apart on the jig lower mold 2 along a direction perpendicular to the axis of the abutting portion 41 of the tail clip 4.

[0051] Multiple tail clips 4 need to work with multiple limiter assemblies. That is, the number of tail clips 4 is equal to the number of limiter assemblies. This allows multiple earphones to be pressure-maintained at once. At the same time, the earphones 3 are placed in a uniform manner, with spacing between them. Adjacent earphones 3 do not touch each other, reducing the risk of scratches on the earphones 3.

[0052] The following is a detailed introduction to the working principle of the headphone tail plug pressure maintaining fixture.

[0053] After the tail plug 31 of the earphone 3 and the middle shell 32 of the earphone 3 are assembled by dispensing glue, they are placed in the lower mold 2 of the jig, and the earphone 3 is placed in the receiving groove 21. For different models of earphones 3, the extension length of the guide column 43 relative to the guide sleeve 44 is adjusted by turning the handle 42 to adapt to the pressure maintenance of earphones 3 of different lengths, ensuring that the abutting part 41 of the tail clip 4 abuts against the tail plug 31 of the earphone 3. The abutting part 41 of the tail clip 4 abuts against the tail plug 31 of the earphone 3 to form pressure, ensuring that there is no gap between the tail plug 31 and the middle shell 32 of the earphone, and the pressure is maintained and allowed to stand for 30 minutes to ensure that the hot melt adhesive is effectively combined with the middle shell and tail plug of the earphone. After the pressure maintenance is cancelled, the tail plug has no gap and does not fall off, which reduces the physical fatigue of workers caused by pulling rubber bands for a long time and improves assembly efficiency.

[0054] The content of this application is not limited to the examples listed in the embodiments. Any equivalent transformations made by ordinary technicians in this field to the technical solutions of this application after reading the description of this application are covered by the claims of this application.
