Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically a connector kit. Background Technology

[0002] In the current field of electronic devices, power supply and data transmission typically rely on separate connectors, such as high-voltage power connectors for power supply and Type-C data connectors for data exchange. This separate approach has several drawbacks: First, devices require multiple interfaces, which not only occupies a significant amount of space but also affects the overall aesthetics of the device. Second, users need to perform multiple plugging and unplugging operations during use, which is inefficient and easily leads to confusion between different interfaces, causing inconvenience. Furthermore, traditional snap-fit ​​or threaded locking structures are complex to operate and prone to loosening when the device is subjected to external forces such as vibration, affecting the reliability of the connection. Additionally, the lack of effective isolation between high and low voltage circuits can easily generate electromagnetic interference, thus affecting the stability of transmission. Therefore, those skilled in the art have provided a connector kit to solve the problems mentioned in the background art. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model enables simultaneous transmission of high-voltage power and low-voltage TYPE-C data / power using a single connector, reducing the number of device interfaces, such as from 2 interfaces to 1, saving space and improving aesthetics; the elastic buckle's "press to unlock, insert to lock" mechanism allows for simultaneous insertion and removal with two fingers, solving the cumbersome problems of traditional threads and complex buckles.

The circuit module includes a PCB board 7 fixed to the male plug base 1 by screws, and a high-voltage transmission male plug 8 for high-voltage transmission and a low-voltage transmission TYPE-C male plug 9 for low-voltage data or power transmission integrated on the PCB board 7. The female plug base 3 is equipped with a high-voltage transmission female socket 10 that is compatible with the high-voltage transmission male plug 8 and a low-voltage transmission TYPE-C female socket 11 that is compatible with the low-voltage transmission TYPE-C male plug 9.

[0023] By adopting the above technical solution, high-voltage power and low-voltage TYPE-C data / power transmission can be realized simultaneously with a single connector, reducing the number of device interfaces, such as from 2 interfaces to 1, saving space and improving aesthetics.

[0024] The male socket base 1 has pressing grooves 101 and mating grooves 102 on opposite side walls. The locking mechanism includes elastic buckles 6 installed on opposite side walls of the male socket base 1. The elastic buckles 6 have pressing parts 601 exposed in the pressing grooves 101 and limiting buckles 602. The elastic buckles 6 are engaged in the mating grooves 102 through the limiting buckles 602 to achieve the connection between the male socket base 1 and the female socket base 3. The gap between the pressing parts 601 and the pressing grooves 101 is 0.1-0.5mm.

[0025] After adopting the above technical solution, the "press to unlock, insert to lock" mechanism of the elastic buckle 6 can be completed by simultaneous operation of two fingers, solving the cumbersome problems of traditional threads and complex buckles.

[0026] The male connector cover 2 is screwed onto the male connector base shell 1 to encapsulate the internal components. The female connector cover 4 is screwed onto the female connector base shell 3. The connecting wire 5 connects the high-voltage transmission female socket 10 and the low-voltage transmission TYPE-C female socket 11 inside the female connector base shell 3.

[0027] Among them, the high-voltage transmission male plugs 8 on PCB board 7 are physically isolated from each other and from the low-voltage transmission TYPE-C male plugs 9 by insulating partitions or layered wiring. The thickness of the insulating partitions is ≥1mm, and the spacing between the layers of the layered wiring is ≥2mm. The high and low voltage circuits are physically isolated, EMI interference is reduced, and data transmission is error-free and power transmission is lossless.

[0028] Among them, the high-voltage transmission male connector 8 adopts a multi-pin contact structure or a flexible beryllium copper contact piece, with a contact area ≥5mm². 2 It supports transmission up to 600V / 10A and has a contact resistance of ≤50mΩ.

[0029] Among them, the low-voltage transmission TYPE-C male plug 9 supports a reversible design, is compatible with the general specifications of the TYPE-C interface, meets the requirements of data exchange rate ≥10Gbps or low power supply 5V / 3A, and can ensure the convenience of installation of both the low-voltage transmission TYPE-C male plug 9 and the high-voltage transmission TYPE-C male plug.

[0030] The outer side of the connecting wire 5 is equipped with a corrugated protective structure, which can withstand a tensile force of ≥50N and pass ≥1000 bending tests with a bending radius of ≥10mm.

[0031] Among them, the male socket base shell 1 and the female socket base shell 3 are made of insulating and flame-retardant materials, meeting the UL94V-0 flame retardant rating and temperature resistance ≥100℃. The flame-retardant shell and high wear-resistant buckle improve the insertion and removal life and are suitable for harsh environments such as industrial and automotive scenarios. The corrugated line is tensile and bending resistant, improving the overall life of the connector.

[0032] The inner wall of the docking slot 102 is provided with a 30-60° guide slope to facilitate smooth insertion and docking.

[0033] The working principle of this utility model is as follows:

[0034] 1) The assembly process for the male plug is as follows:

[0035] The high-voltage transmission male connector 8 and the low-voltage TYPE-C male connector are soldered to the PCB board 7 and fixed to the male connector base shell 1 with screws; the elastic buckle 6 is inserted into the mounting groove of the male connector base shell 1 to ensure that the pressing part 601 is aligned with the pressing groove 101 with a gap of 0.2mm; the male connector shell cover 2 is fastened and fixed by the buckle to complete the male connector encapsulation.

[0036] 2) The assembly process for the female socket is as follows:

[0037] The high-voltage transmission female socket 10 and the low-voltage TYPE-C female socket are embedded into the female socket base shell 3, and the internal circuits are welded on. The female socket shell cover 4 is fastened on. The connecting wire 5 is welded to the circuit interface of the female socket to realize the electrical connection with the high-voltage transmission female socket 10 and the low-voltage TYPE-C female socket. The corrugated structure is used to enhance the tensile strength.

[0038] 3) The male and female docking and separation operations are as follows:

[0039] During docking, the male plug is aligned with the female socket protrusion and inserted axially. The limiting buckle 602 of the elastic buckle 6 automatically engages with the limiting buckle groove of the female socket base 3, achieving mechanical locking.

[0040] When separating, press the pressing part 601 in the pressing groove 101 of the male plug base shell 1 with your thumb. The elastic buckle 6 retracts, the limit buckle 602 disengages from the groove, and the male plug is pulled out axially to complete the separation.

[0041] 4) Transmission performance verification:

[0042] In terms of high-voltage transmission, it supports voltages of 24V-600V and currents of 3A-10A. According to the design adjustment, it can work continuously for 8 hours with a contact temperature rise of ≤20℃ and an ambient temperature of 25℃, meeting the industrial-grade stability requirements.

[0043] For low-voltage Type-C transmission, data transfer supports the USB 3.2 protocol, with a speed of 10Gbps and a bit error rate of ≤10%. -9 Power transmission supports 5V / 3A 15W power supply to meet the fast charging needs of mobile phones and tablets.

[0044] 5) Environmental adaptability test:

[0045] During the vibration test, the male and female connections remained intact and the circuit transmission was normal, with a 10-500Hz sweep vibration lasting for 30 minutes.

[0046] In the flame retardant test, the casing was tested by UL94V-0 and self-extinguished after burning with an open flame for 10 seconds without dripping.

[0047] In the life test, the elastic buckle 6 was inserted and removed ≥10,000 times, and the contact resistance change was ≤10%; the connecting wire 5 was bent ≥1,000 times, and the conductivity was normal.
