Abstract

Technical Field

[0002] With the diversified development of electronic devices, the connection requirements between devices are becoming increasingly complex. Due to defects such as fixed interface types and single functions, traditional electronic connectors are gradually unable to meet user needs. For example, existing connectors usually only support a single standard interface (such as USB, HDMI). When a device needs to be compatible with multiple interfaces, it can only be achieved by splicing multiple independent connectors, resulting in a bulky volume, cumbersome installation, and prominent signal interference problems between different interfaces. In addition, problems such as insufficient heat dissipation in high-power transmission scenarios, interface looseness caused by frequent plugging and unplugging, and the risk of misplugging also restrict the reliability and service life of the connectors.

[0025] Next, the technical solutions in the embodiments of the present invention patent will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention patent. Obviously, the described embodiments are only a part of the embodiments of the present invention patent, rather than all the embodiments. Based on the embodiments of the present invention patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention patent.
[0026] Such as Figures 1-4As shown in the figure, the present invention patent provides a modular combined multi-interface electronic connector, including a base 1, a plurality of detachable interface modules 2, an elastic locking member 3, a combined circuit board 101, and module connection terminals 201. The module connection terminals 201 are arranged along the length direction of the base 1 and form elastic contact with the contact areas of each interface module 2. Each of the interface modules 2 includes a module housing and at least two different types of standard interfaces, and the standard interfaces are integrated on the module housing in a side-by-side or stacked manner.
[0027] The base 1 is provided with a locking groove and two horizontally arranged mounting grooves 103 on the front end face of the base 1. Symmetrically arranged guiding grooves 301 are provided on the inner walls of the mounting grooves 103. The elastic locking member 3 is arranged at the rear of the module housing and forms a snap-fit with the locking groove on the base 1. A guiding block that matches the guiding groove 301 is provided on the side wall of the module housing.
[0028] The combined circuit board 101 includes a signal processing layer 104, a power distribution layer 105, and elastic contacts 202 that are arranged in layers. Vertical conduction is achieved between the signal processing layer 104 and the power distribution layer 105 through the elastic contacts 202.
[0029] In this embodiment, the base 1 serves as the main support. The two mounting grooves 103 on both sides guide the insertion of the interface module 2 through the guiding grooves 301 and guiding blocks to ensure module alignment. The elastic locking member 3 is snap-connected to the locking groove of the base 1, and a locking force is generated by elastic deformation to fix the interface module 2. The module connection terminals 201 are in elastic contact with the contacts of the interface module 2 to achieve electrical conduction and adapt to the small displacements during module insertion and extraction. The combined circuit board 101 adopts a layered design: the signal processing layer 104 (transmits data), the power distribution layer 105 (supplies power), and the elastic contacts 202 (vertical conduction between layers), and the circuits of each layer are independently optimized for performance. The interface module 2 integrates at least two side-by-side or stacked standard interfaces (such as USB + HDMI, Type-C + audio), and function expansion is achieved by replacing the module.
[0030] In this embodiment, different interface modules 2 can be freely combined to meet diverse requirements, reduce customization costs, simplify the installation process, prevent module misalignment, ensure the stability of electrical connection, perform layered processing of signals and power, reduce interference, and improve transmission quality. The elastic contacts 202 avoid welding and are convenient for maintenance. The stacked / side-by-side interface layout saves space and meets the requirements of miniaturized devices.
[0031] Furthermore, the guiding groove 301 has a T-shaped structure, and an anti-disengagement protrusion is provided at the bottom of the guiding groove 301. The guiding block is correspondingly provided with deformable claws. The T-shaped guiding groove 301 restricts the lateral offset of the module. The anti-disengagement protrusion at the bottom engages with the deformable claws of the guiding block to prevent the module from accidentally falling off. The guiding accuracy is improved, and the anti-vibration performance is enhanced, which is suitable for in-vehicle / industrial scenarios. The anti-disengagement design avoids the loosening problem caused by frequent plugging and unplugging.
[0032] Furthermore, the elastic locking member 3 includes a U-shaped elastic piece and a hemispherical chuck provided at the end of the elastic piece. The inner wall of the locking groove is provided with wavy tooth patterns adapted to the chuck. The U-shaped elastic piece is compressed to generate a resilience force, and the hemispherical chuck at the end engages with the wavy tooth patterns of the locking groove at multiple points to form a progressive locking. The locking force is adjustable to adapt to modules of different thicknesses. The wavy tooth patterns provide multiple locking positions to prevent the module from sliding and enhance the anti-pulling ability.
[0033] Furthermore, an electromagnetic shielding layer is provided between the signal processing layer 104 and the power distribution layer 105. The electromagnetic shielding layer is conductively connected to the metal frame of the base 1 through side conductive strips. The electromagnetic shielding layer (such as a metal foil) is sandwiched between the signal layer and the power layer, and forms a grounding loop with the metal base 1 through side conductive strips to absorb high-frequency interference. The signal crosstalk is reduced, the EMC performance is improved, and the requirements for high-speed transmission (such as USB4 / Thunderbolt interface) are met. The shielding layer and the base 1 are integrally grounded, and no additional shielding cover is required, making the structure more compact.
[0034] Furthermore, an expansion interface is provided at the bottom of the base 1. The expansion interface includes positioning posts, a magnetic adsorption ring, and an expansion terminal group connected to the combined circuit board 101. The magnetic adsorption ring assists the base 1 to quickly adsorb and align with the expansion device, and the positioning posts ensure the accurate insertion of the expansion terminals. It supports hot-plugging expansion (such as external storage / charging dock). The expansion terminal group provides additional power / data channels. The magnetic adsorption simplifies the blind plugging operation and improves the user experience.
[0035] Furthermore, an anti-misinsertion structure is provided on the front surface of the module housing. The anti-misinsertion structure includes an identification protrusion at the top of the module housing and an identification groove at the bottom. The identification protrusions and identification grooves of two adjacent interface modules 2 form an interlocking fit. The identification protrusion at the top and the identification groove at the bottom of the module housing form a unique matching relationship. When adjacent modules are interlocked, only the correct arrangement and combination are allowed. The physical anti-fooling design avoids the incorrect installation of the interface module 2 (such as misinserting the HDMI module into the power slot), protecting the safety of the device. The interlocking between modules enhances the overall structural strength.
[0036] Further, a heat dissipation component 203 is provided at the rear of the base 1. The heat dissipation component 203 includes a heat sink thermally connected to the combined circuit board 101 and a fin group provided on the heat sink. The heat sink is in direct contact with the high-heat area of the circuit board 101 (such as the power management chip), and the fin group increases the heat dissipation area to cool down by air convection. This solves the heat dissipation problem of high-power interfaces (such as PD fast charging), avoids overheating and frequency reduction, and improves the long-term stability in high-current scenarios.
[0037] Further, a combined connection mechanism 102 is provided on one side of the base 1. The combined connection mechanism 102 includes a magnetic positioning block, a conductive connection post provided on the magnetic positioning block, and a locking knob for connecting to an adjacent base 1. The magnetic positioning block enables quick splicing of multiple bases 1, the conductive connection posts connect the circuits of each base 1 in series, and the locking knob mechanically strengthens the connection points. It supports horizontal / vertical expansion (such as building a multi-port matrix) to meet the needs of servers / workstations. The magnetic + mechanical double-insurance design takes into account both installation efficiency and connection reliability.
[0038] Further, a combined connection mechanism is provided on one side of the base. The combined connection mechanism includes a magnetic positioning block, a conductive connection post provided on the magnetic positioning block, and a locking knob for connecting to an adjacent base. The magnetic positioning block enables quick splicing of multiple bases, the conductive connection posts connect the circuits of each base in series, and the locking knob mechanically strengthens the connection points. It supports horizontal / vertical expansion (such as building a multi-port matrix) to meet the needs of servers / workstations. The magnetic + mechanical double-insurance design takes into account both installation efficiency and connection reliability.
