Description

Technical Field

[0001] This utility model relates to the field of aviation socket technology, specifically to a wiring structure for a power supply device. Background Technology

[0002] In the field of electrical connections, aviation sockets, as high-end connectors, differ fundamentally from ordinary sockets. Ordinary sockets are designed for home and commercial applications, with simple structures and cost-sensitive features, typically supporting only a single point of mating. Aviation sockets, on the other hand, are designed to meet high reliability, environmental requirements, and long lifespan needs. However, existing aviation sockets still have shortcomings: Existing rail-mounted aviation sockets generally have a height of ≥45 mm, which takes up a lot of space. However, the space in aircraft is small, which can easily lead to additional stress concentration and fatigue fracture of the aviation sockets.

[0003] Currently, aviation sockets have low sealing performance, and structural gaps can easily accumulate dust and corrosive substances in high-altitude environments, inducing micro-corrosion of the circuits, increasing contact resistance, and affecting lifespan.

[0004] It is evident that traditional aviation sockets are not highly precise in both electrical and structural aspects, affecting their safety when used at high altitudes. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wiring structure for a power supply device. This wiring structure has the advantages of small size, high voltage resistance, high current resistance and good electrical isolation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The wiring structure for providing the power supply device includes: The female connector has several holes on its front side, which extend from the front to the back of the female connector. The inner core is embedded inside the female socket. The inner core is provided with several female pins. The female pins are arranged along the axial direction of the socket. One end of the female pin extends to the outside of the front of the female socket for connection with the power supply device. The other end of the female pin is inserted into the corresponding socket from the front of the female socket and extends to the back of the female socket to form a plug-in contact end. The male connector has a front end that is compatible with the back end of the female connector. The back end of the male connector has a recessed mounting groove. The male connector is provided with several male pins. One end of the male pin is inserted into the corresponding hole of the female connector to form a reliable electrical contact with the female pin. The other end of the male pin extends into the mounting groove for electrical connection with an external wire assembly. The mounting groove is filled with filler adhesive, which covers the connection area between the thread assembly and the male needle to form a sealed and waterproof structure. A cover plate that fits over the opening of the mounting groove and is sealed to the back of the male seat.

[0007] In some embodiments, the sidewall of the mounting groove is provided with a plurality of wire holes, and a plurality of the wire groups enter the mounting groove through the corresponding wire holes and are connected to the male pin.

[0008] In some embodiments, the front of the male seat is provided with several upright guide sleeves, each male pin extends into the corresponding guide sleeve, and the male pin is inserted into the insertion hole through the guide sleeve.

[0009] In some embodiments, the male needle has a retaining spring in the middle, and the retaining spring abuts against the end of the male needle and connects to the female needle.

[0010] In some embodiments, the wire assembly is 16AWG UL10368 stranded tin-plated soft copper wire.

[0011] In some embodiments, a through hole is provided on the top surface of the cover plate, the through hole extends through the cover plate along the thickness direction, and a first screw is provided in the through hole. After the first screw passes through the through hole from the top surface of the cover plate, it is sequentially fastened to the male and female seats.

[0012] In some embodiments, the bottom surface of the cover plate is provided with a first blind hole, the opening of the first blind hole facing the male seat, and a second screw is provided on the male seat. The second screw passes through the front of the male seat and is screwed into the first blind hole, thereby locking the male seat and the cover plate.

[0013] In some embodiments, the inner core includes a substrate parallel to the end face of the female base, and a plurality of female pins are embedded and fixed to the substrate in an array, with both ends of each female pin extending out of the corresponding side plate surface of the substrate.

[0014] In some embodiments, the front of the female base has a recessed mounting position, and the substrate is embedded in the mounting position.

[0016] The beneficial effects of the wiring structure of the power supply device of this utility model: The wiring structure of this utility model's power supply device features a core female pin and a male connector male pin that are both recessed into their corresponding sockets for a sealed fit. This prevents the female pin and terminals from being exposed in high-altitude environments, allowing for precise millimeter-level control of electrical clearance and creepage distance, significantly reducing the risk of high-voltage breakdown. The filling adhesive protects the male connector wire assembly mounting groove, covering the wire assembly and the male pin solder joints. The press-fit cover seals again, isolating moisture and salt spray, and suppressing partial discharge, ensuring leak-free operation over long periods. The socket's internal multi-pin, multi-terminal array reduces the overall size of the socket, bringing gaps close to zero, preventing dust and dirt from adhering. This further reduces the bulk of the metal casing, avoiding the dust accumulation and heat dissipation problems associated with traditional heavy structures, improving the reliability of aviation sockets, and making them suitable for mass production and application.

[0026] Example 1 The wiring structure of the power supply device disclosed in this embodiment is as follows: Figures 1-4 As shown, it includes: The female connector 1 has several holes 2 on its front side, which extend from the front side of the female connector 1 to the back side. The front of this female connector 1 has multiple sockets 2; these sockets 2 are through-hole type, that is, they extend from the front to the back, forming a through-hole 17 structure. The inner core 3 is embedded inside the female base 1. The inner core 3 is provided with a plurality of female pins 4. The female pins 4 are arranged axially along the insertion hole 2. One end of the female pin 4 extends to the outside of the front of the female base 1 for connection with the power supply device. The other end of the female pin 4 is inserted into the corresponding insertion hole 2 from the front of the female base 1 and extends to the back of the female base 1 to form a plug-in contact end. Specifically, the inner core 3 is embedded inside the female connector 1. This inner core 3 is an independent component, embedded within the female connector 1 body, and is not integrally formed. The female pin 4 is part of the inner core 3 and is not directly formed into the female connector 1. The female pin 4 is coaxial with the socket 2, providing contact for the subsequent insertion of the male pin 8 on the male connector 6. One end of the female pin 4 is exposed for connection to an external power supply device, which can be a PCB, wire harness, etc. The other end passes through the insertion hole 2 to form the insertion contact end, which is the part of the male pin 8 of the male socket 6 that contacts the female pin 4 when it is inserted.

[0027] The male connector 6 has its front side adapted to mate with the back side of the female connector 1. The back side of the male connector 6 has a recessed mounting groove 7. The male connector 6 is provided with several male pins 8. One end of the male pin 8 is inserted into the corresponding insertion hole 2 of the female connector 1 to form a reliable electrical contact with the female pin 4. The other end of the male pin 8 extends into the mounting groove 7 for electrical connection with an external wire assembly. Specifically, the front of the male connector 6 is assembled with the back of the female connector 1. The back of the male connector 6 is recessed, forming an installation space to accommodate the wire assembly or soldering area. The male pin 8 is an internal fixed structure of the male connector 6 and is not an exposed independent component. The front end of the male pin 8 is inserted into the socket 2, achieving electrical conductivity with the insertion end of the female pin 4. The rear end of the male pin 8 extends into the mounting groove 7 for connection with external wire assemblies.

[0028] The mounting groove 7 is filled with filler adhesive 9, which covers the connection area between the thread assembly and the male needle 8 to form a sealed and waterproof structure. The mounting groove 7 is filled with filler adhesive 9, which covers the entire connection area between the thread assembly and the male needle 8 in one go. After curing, it forms a continuous, seamless, sealed and waterproof body, which isolates the connection area from the external environment.

[0029] The cover plate 10 covers the opening of the mounting groove 7 and is sealed to the back of the male seat 6.

[0030] In this embodiment, the side wall of the mounting groove 7 is provided with a plurality of wire holes 15, and the plurality of wire groups enter the mounting groove 7 through the corresponding wire holes 15 and are connected to the male pin 8.

[0031] The side wall of the mounting groove 7 is provided with several wire holes 15, each wire hole 15 corresponding to a male needle 8; the wire body assembly passes through the corresponding wire hole 15 into the mounting groove 7 and is electrically connected to the male needle 8; and the periphery of the wire hole 15 and the wire body assembly are integrally sealed by filler glue 9 to form a seal between the wire hole 15 and the wire body assembly.

[0032] In this embodiment, the male seat 6 is provided with several upright guide sleeves 16 on its front side, and each male pin 8 extends into the corresponding guide sleeve 16. The male pin 8 is inserted into the insertion hole 2 through the guide sleeve 16.

[0033] To achieve precise mating between the male connector 6 and the female connector 1 and to protect the male pin 8, several upright guide sleeves 16 are integrally formed on the front of the male connector 6. The number and position of the guide sleeves 16 correspond one-to-one with the insertion holes 2 of the female connector 1, and their inner holes are coaxial with those of the insertion holes 2. Each male pin 8 extends from the body of the male connector 6, passes through and is hidden in the corresponding guide sleeve 16. When the male connector 6 and the female connector 1 are mated, the guide sleeve 16 first inserts into the insertion hole 2 of the female connector 1, and uses the gap between its outer cylindrical surface and the inner wall of the insertion hole 2 to achieve automatic centering; then the male pin 8 smoothly slides into the contact area of ​​the female pin 4 along the inner cavity of the guide sleeve 16, avoiding bending deformation of the male pin 8 due to eccentricity or collision.

[0034] In this embodiment, the male needle 8 is provided with a retaining spring in the middle, and the retaining spring abuts against the end of the male needle 8 and connects to the female needle 4.

[0035] The middle section of each male pin 8 is stamped to form a pair of symmetrical retaining springs. When the male pin 8 is pressed into the guide sleeve 16 from the back of the male seat 6, it prevents it from retracting under external tension, ensuring low resistance, vibration resistance, and long service life of the electrical connection. The retaining springs and male pin 8 are integrally stamped, eliminating the need for additional parts, simplifying assembly and improving reliability.

[0038] At least one pair of through holes 17 are formed in the central area of ​​the cover plate 10. The through holes 17 extend along the thickness direction of the cover plate 10, and the diameter of the holes is slightly larger than the outer diameter of the thread of the first screw. The first screw is a stainless steel Phillips head machine screw, which passes through the pre-set threaded blind holes on the back of the cover plate 10 and the male seat 6 in sequence, and continues to be screwed into the corresponding metal insert nut on the back of the female seat 1, so as to achieve a three-layer integrated fastening of the cover plate 10, the male seat 6, and the female seat 1. The screw head is recessed into the countersunk hole on the top surface of the cover plate 10 to ensure that the top of the screw does not exceed the top surface of the cover plate 10 to avoid assembly interference.

[0039] In this embodiment, the bottom surface of the cover plate 10 is provided with a first blind hole 20, the opening of the first blind hole 20 faces the male seat 6, and a second screw is provided on the male seat 6. The second screw passes through from the front of the male seat 6 and is screwed into the first blind hole 20, and the male seat 6 is locked with the cover plate 10.

[0040] To enhance the pull-out resistance between the cover plate 10 and the male seat 6, several first blind holes 20 are integrally formed on the bottom surface of the cover plate 10, with the openings of the blind holes facing the male seat 6 and gold threads embedded in the holes. A through hole 17 is opened at the corresponding position on the male seat 6, and a second screw is inserted from the front of the male seat 6, passes through the through hole 17, and is screwed into the first blind hole 20 of the cover plate 10.

[0041] In this embodiment, the inner core 3 includes a substrate 18, which is parallel to the end face of the female base 1. A plurality of female pins 4 are disposed on the substrate 18, and both ends of each female pin 4 extend out of the corresponding side plate surface of the substrate 18.

[0042] The inner core 3 is integrally formed from a substrate 18 and a female pin 4. It is fixed to the substrate 18 by inlay molding; after molding, both ends of each female pin 4 extend out of the corresponding side plate surface of the substrate 18.

[0043] In this embodiment, the front of the female base 1 has a recessed mounting position 19, and the substrate 18 is embedded in the mounting position 19.

[0044] In this embodiment, a second blind hole is provided on one side of the substrate 18, and the opening of the second blind hole faces the female seat 1.
