Description

Technical Field

[0001] This utility model belongs to the field of pogopin technology, and in particular to an ultra-thin car logo with a magnetic PogoPin connector. Background Technology

[0002] In the automotive industry, illuminated car logos serve as important brand identifiers and safety elements, but their internal circuit connection technology has always faced numerous challenges. Traditional logo connection methods mostly employ soldering or ordinary plug-in connectors, and these technologies have significant shortcomings when applied to ultra-thin logo designs.

[0003] In existing technologies, conventional pin-type connectors have the following technical drawbacks in practical automotive applications: First, traditional connectors are too large, making it difficult to fit the strict space constraints of ultra-thin car logos (usually less than 5mm thick); second, the assembly process requires precise alignment, is cumbersome, and is susceptible to connection failure due to assembly errors; third, during vehicle operation, road bumps and vehicle vibrations can easily cause the traditional connection structure to loosen, leading to poor contact or even circuit interruption; fourth, when the car logo is subjected to external impact or high-pressure cleaning, the rigid connection structure is prone to connector damage or cable breakage, significantly increasing subsequent maintenance costs.

[0004] As automotive designs trend towards thinner, lighter, and more intelligent designs, the thickness of car logos continues to decrease, placing higher demands on connectivity technologies. While PogoPin connectors are already used in areas such as smart car infotainment systems, their application in ultra-thin car logos still faces unique challenges: the spring-pin structure of conventional PogoPin connectors struggles to achieve stable and reliable connections in ultra-thin logos less than 3mm thick, and traditional magnetic attraction designs cannot meet the vibration stability requirements of car logos during high-speed driving. Existing magnetic PogoPin connectors, while offering advantages such as automatic adsorption and zero insertion force, suffer from uneven magnetic distribution leading to unstable connections in ultra-thin car logo applications. Furthermore, their magnetic properties significantly degrade under extreme temperature conditions (-40℃ to 85℃), affecting their lifespan. In addition, traditional PogoPin connectors struggle to achieve IP67 or higher waterproof ratings in ultra-thin structures, failing to meet the needs of car logos in rainy or snowy weather.

[0005] Therefore, there is an urgent need for an ultra-thin magnetic PogoPin connector for car logos that can meet the constraints of extremely thin space while ensuring the reliability, stability and durability of the connection. Utility Model Content

The vehicle body mounting base has a built-in magnetic PogoPin connector female terminal 4 corresponding to the contact of the magnetic PogoPin connector male terminal 2. The magnetic PogoPin connector male terminal 2 is inserted into the magnetic PogoPin connector. The female terminal 4 of the PogoPin connector; the male terminal 2 of the magnetic PogoPin connector includes: a male copper sleeve 201, a male spring pin 202, a male magnet 203, a male inner core 204, and a male outer core 205. The male magnet 203 is annular and fitted onto the outer wall below the shoulder of the male copper sleeve 201. The male outer core 205 is fitted onto the outer wall of the male copper sleeve 201 and closely adheres to the lower end face of the male magnet 203. The male inner core 204 is embedded in the inner cavity of the male copper sleeve 201. The male spring pin 202 is inserted into the male inner core 205. The male spring pin 202's pin contact 206 passes through the center clearance hole on the male copper sleeve 201 and inserts into the female terminal 4 of the magnetic PogoPin connector. The female terminal 4 of the magnetic PogoPin connector includes: a female copper sleeve 401, a female spring pin shaft (Pin) 402, a female magnet 403, a female inner core 404, and a female outer core 405. The female magnet 403 is annular and is fitted on the outer wall below the shoulder of the female copper sleeve 401. The female outer core 405 is fitted on the female copper sleeve 401. The outer wall of the female end magnet 403 is attached to the lower end face. The inner core 404 of the female end is embedded in the inner cavity of the female end copper sleeve 401. The female end spring needle shaft 402 is inserted into the embedding hole opened in the center of the inner core 404. The female end copper sleeve 401 has a needle tip clearance hole. The needle contact 206 of the male end spring needle 202 passes through the needle tip clearance hole and is inserted into the female end spring needle shaft 402. The male end spring 202 consists of a needle body, a needle contact located at the end of the needle body, and a needle spring fitted on the needle body. The needle body is connected to the wire harness. The female end spring needle shaft consists of a needle shaft seat, a needle shaft installed on the needle shaft seat, and a needle shaft spring fitted on the needle shaft. The needle shaft has a needle hole cavity. The bottom of the needle shaft seat is connected to the wire harness. The diameter of the needle shaft is controlled between 0.6-1.2mm.

[0020] In this embodiment, the car logo body 1 adopts an ultra-thin design with a thickness controlled within the range of 1.5-3mm. It consists of an outer decorative surface, an intermediate circuit layer, and a magnetic PogoPin connector male terminal 2.

[0021] In this embodiment, a positioning magnet 3 is provided on the car logo body 1, and a positioning magnet 3 is installed on the car body mounting base corresponding to the position of the positioning magnet.

[0022] In this embodiment, the sealing ring is made of silicone with a thickness of 0.3-0.5mm. When the male end 2 of the magnetic PogoPin connector and the female end 4 of the magnetic PogoPin connector magnetically attract and compress the sealing ring, the sealing ring undergoes elastic deformation under the action of magnetic attraction, forming an IP67 waterproof and dustproof seal.

[0023] In this embodiment, the attraction force between the male magnet 203 and the female magnet 403 is controlled within the range of 3-8N.

[0025] Working principle: During installation, bring the car emblem body 1 close to the car body mounting base within a range of 5-10mm. The magnetic force automatically guides the alignment. As the distance decreases, the magnetic attraction increases, eventually making the car emblem body 1 fit tightly against the car body mounting base. The spring structure of the needle contact 206 of the male end spring pin 202 is compressed by 0.2-0.5mm upon contact, ensuring reliable electrical connection. The sealing ring undergoes elastic deformation under the action of magnetic attraction, forming an IP67-level waterproof and dustproof seal.
