Description

Technical Field

[0001] This utility model relates to the field of USB MINI DIN interface technology, specifically a three-dimensional integrated component with dual-layer USB and MINI DIN interfaces. Background Technology

[0002] The MINI DIN interface is a common interface structure. In its component distribution, it is usually a split interface, requiring multiple independent interface positions, occupying a larger PCB area, and the crossover of cables is prone to interference. Troubleshooting multiple interface faults is also complicated.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a three-dimensional integrated component with dual-layer USB and MINI DIN interfaces to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: A three-dimensional integrated component with dual-layer USB and MINI DIN interfaces includes a housing. A mating hole is provided on the upper back of the housing, and a mating socket is fixedly installed inside the mating hole. Two sets of tongue slots are provided on the lower surface of the housing. A tongue is provided inside the tongue slot, and a metal spring is fixedly connected to the surface of the tongue. A contact spring is provided on the inner wall of the tongue slot. Multiple sets of pin structures are provided on the bottom of the housing.

[0006] Preferably, the tongue is made of PET material, and the contact spring is made of brass plated with nickel and gold.

[0007] By using a tongue made of PET material to support the contact spring, which is made of brass plated with nickel and then gold, signal attenuation can be reduced and connection stability can be maintained.

[0008] Preferably, a sealing ring is provided at the entrance of the mating hole, and there are multiple sets of sealing rings, which are made of silicone material.

[0009] By embedding a multi-layer silicone sealing ring at the entrance of the mating socket, it is possible to provide elastic deformation to fill the gap when plugging and unplugging the socket, so that radial compression forms a dynamic seal when the plug is inserted.

[0010] Preferably, the mating socket has a liquid sealing structure inside, which is filled inside the mating socket. The main material of the liquid sealing structure is epoxy resin and silicone composite adhesive, and the thickness of the liquid sealing structure is one millimeter.

[0011] The liquid sealing structure, primarily composed of potting epoxy resin and silicone composite adhesive with a thickness of one millimeter, is used to fix cables after curing, preventing liquid from seeping in along the conductors via capillary action, thus achieving IP protection and improving the safety of interface components during use.

[0012] Preferably, the surface of the outer casing is provided with a metal shielding layer, and the outer casing is made of stainless steel.

[0013] By using a stainless steel casing, corrosion resistance is improved, and the entire interface can be fixed and supported by welding. At the same time, the metal shielding layer can isolate signal crosstalk and ensure the stability of high-speed data transmission.

[0014] The beneficial effects of this utility model are as follows: 1. The core value of dual-layer USB integrated MINI DIN lies in its space efficiency and functional integration, making it particularly suitable for scenarios such as automotive electronics and industrial equipment that require multi-protocol signal transmission within a limited space. It reduces wiring complexity through physical integration while retaining the anti-interference characteristics of MINI DIN and the universality of USB, making it the preferred solution for high-end integrated devices.

[0015] 2. The MINI DIN's metal casing provides anti-interference capabilities, ensuring the stability of sensitive signals such as video and sensors; the USB section meets universal charging and data requirements. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] According to an embodiment of the present invention, a three-dimensional integrated component with dual-layer USB and MINI DIN interfaces is provided.

[0021] Example 1; like Figure 1-4 As shown, the three-dimensional integrated component of dual-layer USB and MINI DIN interfaces according to an embodiment of the present invention includes a housing 1. A docking hole 6 is provided on the upper part of the back of the housing 1. A docking socket 7 is fixedly installed inside the docking hole 6.

A metal spring 4 is fixedly connected to the surface of the tongue 3. A contact spring 5 is provided on the inner wall of the tongue slot 2. Multiple sets of pin structures 11 are provided on the bottom of the housing 1.

[0022] In this embodiment, the tongue 3 is made of PET material, and the contact spring 5 is made of brass plated with nickel and gold.

[0023] By using a tongue 3 made of PET material to support the contact spring 5, which is made of brass plated with nickel and then gold, signal attenuation can be reduced and connection stability can be maintained.

[0024] In this embodiment, a sealing ring 8 is provided at the entrance of the mating hole 6. There are multiple sets of sealing rings 8, and the sealing rings 8 are made of silicone material.

[0025] By embedding a multi-layer silicone sealing ring 8 into the inlet of the mating socket 6, an elastic deformation filling gap can be provided when plugging and unplugging the socket, so that the plug is radially squeezed to form a dynamic seal when inserted.

[0026] In this embodiment, a liquid sealing structure 9 is provided inside the docking socket 7. The liquid sealing structure 9 is filled inside the docking socket 7. The main material of the liquid sealing structure 9 is epoxy resin and silicone composite adhesive, and the thickness of the liquid sealing structure is one millimeter.

[0027] The liquid sealing structure 9, made primarily of potting epoxy resin and silicone composite adhesive with a thickness of one millimeter, is used to fix cables after curing, preventing liquid from seeping in along the conductors and achieving IP68 protection, thus improving the safety of the interface components during use.

[0028] In this embodiment, a metal shielding layer 10 is provided on the surface of the outer shell 1, and the outer shell 1 is made of stainless steel.

[0029] By using a stainless steel housing 1, corrosion resistance can be improved, and the entire interface can be fixed and supported by welding. At the same time, the metal shielding layer 10 can isolate signal crosstalk and ensure the stability of high-speed data transmission.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical applications: 1. Interface Preparation The integrated components are soldered to the PCB board via the pin structure 11 at the bottom, achieving electrical connection and mechanical support.

[0032] The stainless steel housing 1 provides structural rigidity, and the metal shielding layer 10 on its surface pre-isolates external electromagnetic interference to ensure signal transmission stability.

[0033] 2. MINI DIN interface connection When the MINI DIN plug is inserted into socket 6: The plug first contacts the silicone sealing ring 8 at the entrance, and elastic deformation is generated by radial compression to fill the gap between the plug and the socket, forming a dynamic seal.

[0034] The plug continues to extend into the mating socket 7, establishing an electrical connection with the internal contacts.

[0035] The liquid-sealed structure uses epoxy resin and silicone composite adhesive to wrap around the cable root after curing, preventing liquid capillary seepage and achieving IP68 protection.

[0036] 3. USB interface connection Insert the USB plug along the tongue slot 2: The PET tongue 3 guides the plug positioning, and the metal spring 4 on its surface contacts the metal shell of the plug to provide a grounding path.

[0037] The plug terminals and contact springs are elastically crimped with nickel-plated and gold-plated brass to reduce signal attenuation and maintain connection stability.

[0038] 4. Data transmission and protection Dual-layer three-dimensional layout: The upper layer of MINI DIN processes interference-sensitive signals such as video / sensors; the lower layer of USB is responsible for general data and charging, with physical isolation to reduce crosstalk.

[0039] Continuous protection: The stainless steel outer shell resists environmental corrosion, and the liquid sealing structure and multi-layer silicone sealing rings work together to deal with liquid intrusion and dust contamination.

[0040] 5. Fault Maintenance A single integrated component replaces the traditional split interface, simplifying the wiring structure. In case of a fault, only one interface needs to be checked, improving maintenance efficiency.

[0041] In summary, the core value of integrating a MINI DIN with a dual-layer USB port, achieved through the above-described technical solution of this utility model, lies in its space efficiency and functional integration. It is particularly suitable for scenarios such as automotive electronics and industrial equipment where multi-protocol signal transmission needs to be achieved within a limited space. By physically integrating the MINI DIN, it reduces wiring complexity while retaining the anti-interference characteristics of the MINI DIN and the universality of USB. This makes it a preferred solution for high-end integrated devices. The metal casing of the MINI DIN provides anti-interference capabilities, ensuring the stability of sensitive signals such as video and sensors; the USB portion meets universal charging and data requirements.
