Description

Technical Field

[0001] The present application relates to the technical field of hearing aids, and in particular to a terminal and a hearing aid. Background Art

[0002] As the number of hearing-impaired patients continues to increase, the market demand for hearing aids as auxiliary hearing devices is increasing. However, the terminal design of existing hearing aids has obvious defects, especially in terms of tensile strength and reliability.

[0003] Traditional hearing aid terminal designs usually adopt an empty tube structure, that is, the electrical signal transmission between the hearing aid host and the speaker is realized by inserting enameled wire inside the empty tube. The main problem with this design is that the tensile strength and reliability of the terminal are completely dependent on the strength of the empty tube itself. Due to the structural and material limitations of the empty tube, it is often difficult to withstand large tensile forces, so it is easy to break or damage, causing the hearing aid to not work properly. Users have to frequently replace the hearing aid terminals, which not only increases the cost of use, but also reduces the user experience.

[0004] Therefore, there is an urgent need to develop a new type of hearing aid terminal that can significantly improve tensile strength and reliability while ensuring good electrical signal transmission performance. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a terminal and a hearing aid, which solve the problems of the prior terminal in terms of tensile strength and reliability through innovative structural design and material selection.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A terminal, used in hearing aids, comprising a plug connector, an enameled stranded wire and an insulating sheath;

[0008] One end of the enameled stranded wire is fixed in the plug connector. The enameled stranded wire comprises a reinforcing fiber and a plurality of enameled single wires. The reinforcing fiber is arranged at the center of the plurality of enameled single wires, and each enameled single wire is spirally wound around the outer surface of the reinforcing fiber.

[0009] The insulating outer sheath is wrapped around the enameled stranded wire, and the insulating outer sheath and the plug connector are an integral injection-molded structure.

[0010] As a further solution of the utility model, a copper clamp is provided to fix one end of the enameled stranded wire in the plug connector.

[0011] As a further solution of the utility model, the enameled stranded wire includes at least two strands.

[0012] As a further solution of the utility model, the enameled single wire is a silver-plated copper wire, and the diameter of the enameled single wire is not less than 0.05 mm.

[0013] As a further solution of the present invention, the fiber fineness of the reinforcing fiber is not less than 150D.

[0014] As a further solution of the present invention, the reinforcing fiber is Kevlar fiber.

[0015] As a further solution of the utility model, the insulating sheath is a nylon insulating sheath.

[0016] As a further solution of the utility model, the length of the reinforcing fiber is smaller than the length of each strand of the enameled single wire.

[0017] A hearing aid comprises a hearing aid host, on which the above-mentioned terminal is arranged.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. In view of the problems of tensile strength and reliability of the existing terminal empty tube threading structure, the utility model sets the insulating sheath wrapped around the enameled stranded wire and the plug connector as an integral injection molding structure, and fixes one end of the enameled stranded wire in the plug connector, so that the terminal plug connector and the headphone wire become an integrated structure, and the wire is directly pressed out of the plug connector, thereby realizing the integrity and stability of the terminal, enhancing the tensile strength of the terminal, and enabling it to withstand greater external force without being easily broken or damaged.

[0020] 2. The utility model fixes one end of the enameled stranded wire in the plug connector by means of a copper clip, thereby enhancing the adhesion between the enameled stranded wire and the plug connector, while not affecting the transmission of electrical signals. It can effectively prevent signal transmission interruption or distortion caused by loose wires, thereby effectively improving the overall signal transmission performance of the terminal.

[0021] 3. The utility model introduces reinforcing fibers as the central structure of the enameled stranded wire, so that the terminal can better resist deformation and breakage when being pulled or bent by external forces, thereby improving the durability and reliability of the product.

[0022] 4. The utility model adopts a design in which multiple strands of enameled single wires are spirally wound on the outer surface of the reinforcing fiber, which not only enhances the overall structural stability of the enameled stranded wire, but also improves the transmission efficiency and quality of the signal.

[0027] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] This embodiment provides a terminal, which is intended to solve the problem of insufficient tensile strength and reliability of the terminal in the prior art, while ensuring good electrical signal transmission performance, and is suitable for general hearing aids, especially behind-the-ear hearing aids.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, the terminal mainly includes a plug connector 1, an enameled stranded wire 2 and an insulating sheath 3. One end of two or more enameled stranded wires 2 is fixed in the plug connector 1; the insulating sheath 4 is wrapped around the enameled stranded wire 2, and the insulating sheath 4 and the plug connector 1 are an integral injection molding structure.

[0031] One end of the enameled twisted wire 2 is connected to the plug connector 1, and the other end is the receiver terminal 5. The plug connector 1 is the interface for connecting to the hearing aid host, and the receiver terminal 5 can be directly connected to the receiver of the hearing aid. The enameled twisted wire 2 is responsible for transmitting electrical signals between the plug connector 1 and the hearing aid receiver.

[0032] In the present invention, the plug connector 1 is a pluggable plug connector, which is plugged into the hearing aid host, and the plug connector 1 is provided with a buckle that fits with the host, so that the terminal as a whole is easy to replace, which greatly improves the convenience of using the hearing aid. In addition, the integrated injection molding structure of the plug connector also enhances its overall mechanical strength, further improving the reliability of plugging and unplugging.

[0033] A copper clip 3 is provided as a fixing device between the plug connector 1 and the enameled stranded wire 2. The copper clip 3 can effectively fix one end of the enameled stranded wire 2 in the plug connector 1, ensuring that the enameled stranded wire 2 will not loosen or fall off. At the same time, the copper clip 3 also has good electrical conductivity, which can ensure efficient transmission of electrical signals between the plug connector 1 and the enameled stranded wire 2. In specific implementation, the copper clip 3 is first clamped on the enameled stranded wire 2, and then the enameled stranded wire 2 and the copper clip 3 are coated together through an injection molding process, so that the injection molded part, that is, the terminal, can tightly wrap the copper clip 3 and the enameled stranded wire 2, preventing the enameled stranded wire 2 from moving along the length direction, thereby preventing the enameled stranded wire 2 from loosening.

[0034] As a preferred embodiment, in the structure of the enameled stranded wire 2, reinforcing fibers are introduced as the central structure. The reinforcing fibers are arranged at the center of the multiple enameled single wires, and each enameled single wire is spirally wound on the outer surface of the reinforcing fibers, and the length of the reinforcing fibers is less than the length of each enameled single wire; when the wire is pulled, the pulling stress is mainly concentrated on the reinforcing fibers to avoid pulling the enameled single wires, thereby protecting the wire and the terminal structure. This structure not only enhances the overall tensile strength of the enameled stranded wire 2, but also enables the enameled stranded wire 2 to better disperse stress and prevent breakage when subjected to external force; at the same time, the insulating sheath 4 can also protect the enameled stranded wire 2 from mechanical damage, thereby improving the durability of the product.

[0035] It is worth noting that multiple strands of enameled single wires are spirally wound on the outer surface of the reinforcing fiber, and the spiral winding design enables the multiple strands of enameled single wires to be tightly and evenly distributed on the outer surface of the reinforcing fiber, forming a stable supporting structure. This structure can not only effectively resist external tension and torsional forces, but also maintain a stable shape during use, thereby ensuring that the enameled stranded wire can maintain its original performance in various complex environments. In addition, the spiral winding design also helps to improve the quality of the signal. Since a stable electrical connection is formed between the multiple strands of enameled single wires, the signal can maintain continuity and stability during transmission, avoiding signal distortion or interruption caused by poor connection or looseness. Therefore, the design of multiple strands of enameled single wires spirally wound on the outer surface of the reinforcing fiber adopted in the utility model not only significantly enhances the overall structural stability of the enameled stranded wire by strengthening the feature of spiral winding, but also improves the transmission efficiency and quality of the signal.

[0036] In this embodiment, the reinforcing fiber is preferably Kevlar fiber, and its fiber fineness is 150D to ensure the strength and toughness of the fiber; 14 strands of silver-plated copper wire are used as the enameled single wire, and its diameter is not less than 0.05mm, so that the tensile strength of the enameled stranded wire 2 can reach more than 5kg.

[0037] This embodiment also provides a hearing aid, which includes a hearing aid host and a terminal described in this embodiment. By applying the terminal to the hearing aid host, the overall performance of the hearing aid is improved. The hearing aid has excellent tensile strength and reliability, so that the hearing aid can maintain stable performance during long-term use.

[0038] In summary, this embodiment provides a terminal and its application, which forms an integral injection molding structure of the insulating sheath and the plug connector, and fixes one end of the enameled stranded wire in the plug connector, so that the terminal plug connector and the headphone wire become an integral structure, and the wire is directly pressed out of the plug connector, thereby achieving the integrity and stability of the terminal structure, and at the same time, the structural design of reinforcing fiber and multiple enameled single wires is introduced, which significantly improves the tensile strength and reliability of the terminal, and ensures good electrical signal transmission performance. This design not only solves the problems existing in the prior art, but also improves the overall performance and service life of the hearing aid.
