Description

Technical Field

[0001] The utility model relates to the technical field of earphone sockets, in particular to a high-grade waterproof earphone socket. Background Art

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers placed close to the ears. Headphones are typically detachable from the media player, connecting with a single plug. Their advantage is that they allow users to listen to audio without disturbing others. They also block out ambient noise, making them particularly useful in noisy environments such as recording studios, bars, travel, and sports.

[0003] As headphones are used in more and more places, sometimes there is water in the environment where they are used. The headphone jack is a channel for water to enter the phone. In order to prevent water from entering the phone, this channel must be blocked, which requires the headphone socket to have a waterproof function.

[0004] Therefore, how to provide a high-grade waterproof headphone socket has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to provide a high-grade waterproof earphone socket.

[0006] To achieve the above-mentioned purpose, the utility model provides a high-grade waterproof earphone socket, including: an earphone socket shell, a mounting portion preset inside the earphone socket shell for installing a terminal mechanism, the earphone socket shell adopts an integrally formed structure, the mounting portion of the earphone socket shell and the terminal mechanism are sealed with sealant, one end of the terminal mechanism extends from a through-hole portion preset at the rear of the earphone socket shell to the outside, and a baffle is added to the through-hole portion at the rear of the earphone socket shell, and then filled with high-temperature resistant waterproof resin to seal it for waterproofing.

[0007] The headphone jack shell is made of high-strength and tough engineering plastic injection molding to avoid assembly errors that may lead to liquid or gas leakage. The mounting part is a plastic groove that matches the model and size of the corresponding terminal mechanism, so that the terminal mechanism can be inserted into the matching plastic groove to achieve a perfect fit. In order to ensure the flatness of the flat lead-out pins ≤0.05mm, a shaping fixture is designed in the assembly process, and a flat slide plate with a height difference of 0.05mm is used in the assembly inspection.

[0008] The main technical performance indicators of this product are as follows:

[0009] 1. The coplanarity of the SMT contact pins is less than 0.05mm.

[0010] 2. The rated load of the connector is DC50V, 0.3A.

[0011] 3. The plug insertion force is ≤30N, the pull-out force is ≥3N, and the internal control standard is 5~15N.

[0012] 4. When the plug is inserted, the contact resistance is ≤50mΩ and the insulation resistance is ≥100mΩ.

[0013] 5. Mechanical life: 6000 times, internal control standard: 10000 times.

[0014] 6. Flame retardant is UL94-V0 grade.

[0015] 7. Adapt to the ambient temperature of -40℃~85℃.

[0016] 8. Overcome the contact and separation sequence between the plug and the spring inside the socket when inserting and removing the plug. (Interchangeability of positioning methods in the inspection report)

[0017] 9. The waterproof grade of connector coating reaches IPX8.

[0018] 10. The finished product complies with the requirements of EU ROHS directive and is an environmentally friendly green product. (Toxic and hazardous substances are tested in the inspection report).

[0019] Preferably, the earphone seat shell is made of plastic material, and the height of the plastic earphone seat shell is 4.2 mm.

[0020] The headphone jack shell made of plastic has the advantages of light weight, good chemical stability, no rust, good impact resistance, good waterproofness, wear resistance, good insulation, poor thermal conductivity and low cost. The headphone jack shell adopts an ultra-thin height design of only 4.2mm, which is ultra-small and ultra-short. This design allows more space for placing other devices.

[0021] Preferably, the terminal mechanism is a reed, and five reeds are correspondingly provided, and the five reeds correspond to L, R, DETECT, GND and MIC.

[0022] The five reeds all adopt the existing structures in the market in this field, among which:

[0023] The functions of L and R are to constitute the left and right channels of the stereo headphones respectively;

[0024] DETECT, the main function is to play a detection role. For example, when a headphone is plugged into the smart device, a "headphone" icon will be displayed on the screen, prompting the user to enter the headphone mode;

[0025] The GND and MIC terminals are used for grounding and microphone functions respectively. Since smart device manufacturers have two different definitions for these two functions, the headphone jack is designed to be universal to meet the needs of different manufacturers, reflecting the practicality of this device.

[0026] Preferably, the wiring harness connecting portion is a wiring harness through hole, and the wiring harness through hole is preset at the front end of the earphone seat shell.

[0027] The harness through hole adopts the existing structure on the market in this field, and is used to connect the earphone seat shell with the external harness.

[0028] Preferably, a sealing ring is provided on the wiring harness through hole.

[0029] The design of the sealing ring seals the gaps and holes on the wiring harness through-holes. This method is common knowledge in the art and will not be described in detail.

[0030] Preferably, the fixing mechanism is a fixing block, and the fixing block is installed on one side of the earphone seat housing, and an internal thread type fixing hole is preset on the fixing block.

[0031] The design of the fixing mechanism makes it easy for the staff to fix the headphone seat shell in the specified position, and the internal thread type fixing hole is designed to be used to insert bolts into the fixing block. This design ensures the stability of the fixed installation of the headphone seat shell while making it easy for the staff to disassemble and assemble the headphone seat shell at a later time, thereby replacing and maintaining the headphone seat shell.

[0032] The beneficial effects of the utility model are:

[0033] 1. When the present invention is in use, the earphone seat shell is integrally injection-molded with high-strength and good-toughness engineering plastic to avoid assembly errors that may lead to leakage of liquid or gas. The 5 functional terminals are rigorously and accurately routed and are all punched out by high-precision dies. They are inserted into the corresponding plastic grooves to achieve a perfect fit and are finally filled with sealant to achieve an IPX8 waterproof rating. The five reeds are all installed through the tail opening of the earphone seat shell, and a baffle is affixed to the tail through-hole. The terminals are then sealed with high-temperature-resistant waterproof resin to achieve a waterproof effect.

[0034] 2. When the present invention is in use, the earphone holder shell adopts an ultra-thin design with a height of only 4.2mm, which has the characteristics of being ultra-small and ultra-short. This design allows more space for placing other devices. Such a narrow earphone holder shell not only has a strong waterproof performance, but also has the function of a microphone earphone, reflecting the practicality of the device, which is conducive to its popularization and use.
