Description

Technical Field

[0001] The utility model relates to a wireless earphone, in particular to a magnetic suction type connector and an earphone. Background Art

[0002] Our company has previously applied for a utility model patent for a battery-detachable headset (2023223109183), which uses a magnetically removable battery. During testing and actual use, we found the following defects: the magnetic conductive component 300 needs to be soldered during the process, and the fixed plastic part 310 and the fixed plastic sheet 340 will deform due to temperature problems during the soldering process, making it impossible to proceed with the subsequent assembly process; and based on the assembly structure of the fixed plastic part 310 and the fixed plastic sheet 340, the conductive metal part 330, that is, the spring, is assembled by means of a plastic guide column (protrusion 311) + glue bonding. Since the spring is subjected to a certain extrusion force during the use of the battery, when conducting the industry standard "3000 times reliability test", it was found that the structure was debonded and separated, resulting in failure to pass the aforementioned test. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a magnetic connector and earphone that solves at least one of the above problems.

[0004] A magnetic connector, comprising: a first connector and a second connector, wherein the first connector and the second connector are connected by magnetic attraction;

[0005] The first joint includes a first PCB board, and the first spring piece is welded to the first PCB board;

[0006] The second connector includes a second PCB board, and the second spring piece is welded to the second PCB board;

[0007] When the first connector and the second connector are connected, the first spring sheet and the second spring sheet are in contact and conduction. By welding the spring sheet on the PCB, the plastic fixing method used in the old model is replaced, which solves the problem that the plastic fixing part is deformed during the welding of the spring sheet, thereby affecting the subsequent assembly process, and improves the reliability of the product.

[0008] As a further solution of the utility model: one of the first spring piece and the second spring piece is of a plane contact type, and the other is of a contact point type.

[0010] As a further solution of the utility model: the first connector further includes a first magnet and a first magnet fixing seat, and the first magnet is restricted between the first magnet fixing seat and the first PCB board;

[0011] The first magnet is located in the middle of the first magnet fixing seat;

[0012] The second connector further includes a second magnet and a second magnet fixing seat, and the second magnet is restricted between the second magnet fixing seat and the second PCB board;

[0013] The second magnet is located in the middle of the second magnet fixing seat.

[0014] As a further solution of the utility model: the first elastic piece is higher than the surface of the first magnet fixing seat, which is the surface of the first magnet fixing seat facing the second magnet fixing seat.

[0015] Alternatively, the second elastic sheet is higher than a surface of the second magnet fixing seat, which surface is a surface of the second magnet fixing seat facing the first magnet fixing seat.

[0016] The utility model also provides an earphone, comprising any one of the magnetic suction type connectors described above.

[0017] As a further solution of the utility model: the first connector is an earphone terminal, and the second connector is a battery terminal;

[0018] Alternatively, the first connector is a battery connector, and the second connector is an earphone connector.

[0019] The above-mentioned magnetic connector uses a PCB board as a fixing part of the spring, which solves the problem of deformation of the fixing part caused by the welding of the spring in the old solution, reduces the defective rate, and avoids problems in the subsequent installation process.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "center", "longitudinal", "lateral", "up", "down", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] like Figure 1-Figure 2 As shown, a magnetic connector includes a first connector 100 and a second connector 200. In this embodiment, the first connector 100 is an earphone end connector, and the second connector 200 is a battery end connector. The first connector 100 and the second connector 200 can be magnetically attracted to achieve replaceable battery parts.

[0029] The first connector 100 includes a first PCB 110, a first spring piece 120, a first magnet 130 and a first magnet fixing seat 140; wherein the first spring piece 120 is directly welded to the first PCB 110; the first magnet 130 is arranged in the middle part of the first magnet fixing seat 140, and the first magnet 130 is restricted between the first PCB 110 and the first magnet fixing seat 140.

[0030] The second connector 200 includes a second PCB 210, a second spring 220, a second magnet 230, and a second magnet fixing seat 240; the second connector 200 is basically the same in structure as the first connector 100, and the difference between the two is the form of the spring. Specifically, the second spring 220 is embedded in the second magnet fixing seat 240, but there is a gap between the first spring 120 and the first magnet fixing seat 140. The purpose of this gap is to leave space for the deformation of the first spring 120 (the spring needs to produce a certain deformation and generate elastic force to ensure good contact).

[0031] Furthermore, the first spring piece 120 is in a zigzag shape. When the first connector 100 and the second connector 200 are connected, the first spring piece 120 contacts the second spring piece 220. The second spring piece 220 squeezes the first spring piece 120 under the action of the magnetic force, causing the first spring piece 120 to deform. Under the action of the elastic force generated by its own deformation, the first spring piece 120 clings to the second spring piece 220 to achieve stable contact and conduction.

[0032] Furthermore, the first spring clip 120 is welded to a side of the first PCB 110 facing the first magnet fixing seat 140. After the first magnet fixing seat 140 and the first PCB 110 are assembled, the solder joint of the first spring clip 120 will be sandwiched between the two. When the first spring clip 120 is squeezed, the contact part between the first spring clip 120 and the first PCB 110 as a whole transmits pressure to the first PCB 110. Compared with the old model, the force applied to the solder joint of the first spring clip 120 in this embodiment is pressure rather than tension, thereby eliminating the possibility of desoldering.

[0033] Furthermore, the second elastic sheet 220 includes a leg 221 extending from the end, the leg 221 passes through the second magnet fixing seat 240 and the second PCB 210, and the end of the leg 221 is welded to the second PCB 210 on a side of the second PCB 210 away from the second magnet fixing seat 240.

[0034] Compared with the old model, the plastic parts that fix the springs are replaced with PCB boards. In addition to eliminating the problem of plastic parts deformation, the PCB board can also be used as a power circuit board. The power control module is moved out of the headset main board. Relatively speaking, the size of the circuit board of the headset body can be reduced, which is conducive to the overall miniaturization design of the headset.

[0035] Furthermore, regarding the form of the spring piece, in this embodiment, as Figure 5As shown, the first spring clip 120 and the second spring clip 220 are preferably planar spring clips, that is, the contact between the two spring clips is surface contact. In the old scheme, the first spring clip 120 is a contact spring clip, and the second spring clip 220 is a planar spring clip to solve the short circuit problem caused by the relative rotation between the battery end and the earphone end. In this application, this method can also be used, but based on the use of the first PCB, the space is limited, and the zigzag first spring clip 120 is used, which is smaller in size than the old V-shaped spring clip, so that the overall volume of the earphone is controlled to a suitable size.

[0036] Different from the above, if Figure 4 As shown, the first spring piece 120 is a contact spring piece, which includes a base 121, and the base 121 is used for welding with the first PCB 110. One end of the base 121 extends outward and then folds back to form an arc-shaped elastic part 122. The part of the elastic part 122 that is folded back extends upward and folds down to form an arc-shaped contact part 124. The parts on both sides of the elastic part 122 on the base 121 are folded and buckled inward toward the contact part 124 to form a limit part 123. The inward buckling part of the limit part 123 is stuck at the connection between the elastic part 122 and the contact part 124, and the elastic part 122 is limited by the limit part 123. When the contact part 124 is not pressed, the elastic part 122 and the limit part 123 are against each other. When the contact part 124 is pressed, the elastic part 122 is away from the limit part 123.

[0037] As a second embodiment of the present application, the first connector 100 may also be a battery terminal connector, and the second connector 200 may be an earphone terminal connector.

[0038] like Figure 3 As shown, the utility model also provides an earphone, comprising the above-mentioned magnetic suction connector.

[0039] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
