Description

Technical Field

[0001] This utility model relates to the field of waterproof connector technology, specifically to an integrated onboard connector for new energy vehicle instrument panels. Background Technology

[0002] As new energy vehicles rapidly iterate towards intelligence and connectivity, vehicle dashboards have been upgraded from traditional mechanical instruments to core control units that integrate driving data display, intelligent interaction, and multi-system information integration. They need to simultaneously receive and process dozens of power signals and data signals (such as vehicle speed, battery level, navigation, ADAS warnings, etc.) from on-board chips, sensors, power batteries, and autonomous driving systems, which places higher demands on the signal integration capabilities of connectors.

[0003] Currently, traditional connectors require different specifications and wiring harnesses. The terminals, seals, and fixing structures of the connectors are designed in a dispersed manner, occupying a large area of ​​the PCB board. However, intelligent instrument panels need to integrate multiple components such as displays, main control chips, and sensors, making space extremely limited. Traditional connectors cannot meet the requirements for compact installation. At the same time, some connectors lack effective waterproofing designs, making the instrument PCB board susceptible to moisture corrosion, affecting its lifespan and reliability. In addition, the complex wiring harness is also detrimental to the lightweight design of the entire vehicle. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated onboard connector for new energy vehicle instrument panels, which can integrate different wire harness connections and has good sealing and waterproof effects.

[0005] The technical solution adopted by this utility model is: an integrated onboard connector for new energy vehicle instruments, including a male connector and a female connector. One end of the male connector is provided with a plurality of signal pins, and the other end is provided with a fixing platform. One end of the female connector is provided with a terminal block, and the end face of the terminal block is provided with terminal holes arranged in an array for installing signal terminals, which are mated to the signal pins. The end face of the fixing platform of the male connector is provided with an elastic sealing gasket. The end of the female connector is provided with a sealing lip arranged around the terminal block. When the end of the male connector with signal pins abuts against the terminal block, the sealing lip seals against the outer circumference of the male connector.

[0006] In this technical solution, the male connector is soldered to the instrument PCB board via a mounting platform during installation. An elastic sealing gasket fills the gap between the male connector and the PCB board, forming the first seal to prevent water ingress at the male connector mounting location. After the female and male connectors are plugged in and matched, signal transmission is achieved through signal pins and signal terminals. The number of pins and signal terminals is designed according to actual design needs, reducing the number of connectors used. A single integrated connector replaces the traditional solution of multiple independent connectors and complex wiring harnesses, greatly simplifying wiring harness design, reducing wiring harness length and weight, and directly contributing to reducing the overall vehicle weight. Simultaneously, after the female and male connectors are plugged in and matched, the sealing lip of the female connector is inserted into the end of the male connector, forming a second seal at the connection point. This multi-seal structure significantly improves the sealing effect at the connector location, preventing moisture from entering the connector and causing connection failure or damage.

[0007] Preferably, the female connector has a terminal block at one end, and anti-foolproof sockets are symmetrically arranged on both sides of the terminal block. The male connector end face is provided with an anti-foolproof plug that is compatible with the anti-foolproof sockets.

[0008] Preferably, the end face of the fixed platform is provided with a mounting part, an elastic sealing gasket provided on the end face of the fixed platform is arranged around the mounting part, and the edge of the mounting part is provided with a mounting groove for mounting signal pins.

[0009] Preferably, the end of the female connector facing away from the terminal block is provided with a waterproof pad, and the waterproof pad is provided with sealing holes arranged one-to-one with the terminal holes, and each sealing hole is provided with an elastic puncture-type sealing layer.

[0010] Preferably, the outer side of the waterproof pad is provided with a sealing cover plate that is fixed to the connector housing, and the sealing cover plate is provided with positioning holes that correspond one-to-one with the sealing socket.

[0011] Preferably, the outer surface of the female connector is provided with a connecting fastener that engages and fixes with the male connector.

[0012] The beneficial effects of this utility model are as follows: The elastic sealing gasket on the end face of the male terminal fixing platform is compressed and filled during welding and installation, preventing moisture from entering through the installation gap between the male terminal and the PCB board. Simultaneously, the sealing lip of the female terminal connector tightly adheres to the outer circumference of the male terminal after insertion, forming a circumferential sealing band that can withstand relative displacement caused by vehicle vibration, preventing seal failure. Furthermore, the locking and fixing of the female terminal connection buckle ensures a long-term tight fit between the male and female terminals, further strengthening the sealing pressure of the sealing lip. Through integrated, multi-layered waterproofing, and foolproof adaptation, this innovative design comprehensively solves the pain points of existing new energy electric vehicle instrument connectors, possessing high practical value.

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figures 1 to 5As shown in the figure, a specific embodiment of this utility model provides an integrated onboard connector for a new energy vehicle instrument panel, including a male connector 100 and a female connector 200. The male connector 100 has a plurality of signal pins 110 at one end and a fixing platform 120 at the other end. The female connector 200 has a terminal block 210 at one end, and the end face of the terminal block 210 has terminal holes 211 arranged in an array for mounting signal terminals. The signal terminals are plugged into and adapted to the signal pins 110. The end face of the fixing platform 120 of the male connector 100 has an elastic sealing gasket 130. The end of the female connector 200 has a sealing lip 220 arranged around the terminal block 210. When the end of the male connector 100 with signal pins 110 abuts against the terminal block 210, the sealing lip 220 seals and fits against the outer peripheral surface of the male connector 100.

[0023] like Figures 1 to 5 As shown, with the above configuration, in this embodiment, the male connector 100 is soldered to the instrument PCB board via the fixing platform 120 during installation. An elastic sealing gasket 130 fills the gap between the male connector 100 and the PCB board, forming a first seal to prevent water ingress at the installation location of the male connector 100. After the female connector 200 and the male connector 100 are plugged in and matched, signal transmission is achieved by using signal pins 110 and signal terminals to form a signal connection. The number of pins and signal terminals can be designed according to actual design needs, reducing the number of connectors used. A single integrated connector replaces the traditional solution of multiple independent connectors and complex wiring harnesses, greatly simplifying wiring harness design, reducing wiring harness length and weight, and directly contributing to reducing the overall vehicle weight. Simultaneously, after the female connector 200 and the male connector 100 are plugged in and matched, the sealing lip 220 of the female connector 200 is inserted into the end of the male connector 100, thus forming a second seal at the connection location. This multi-seal structure significantly improves the sealing effect of the connector location, preventing moisture from entering the connector and causing connection failure or damage.

[0024] like Figure 5 As shown, the female connector 200 has a terminal block 210 at one end, with anti-foolproof sockets 212 symmetrically arranged along both sides of the terminal block 210. The male connector 100 has an anti-foolproof plug 140 on its end face that is compatible with the anti-foolproof sockets 212. The anti-foolproof sockets 212 on the female end and the anti-foolproof plug 140 on the male end adopt an asymmetrical design, and can only be inserted when the male and female ends are correctly aligned, completely eliminating signal abnormalities or component damage caused by reverse polarity or incorrect terminal insertion, reducing the assembly mis-insertion rate to 0.

[0025] like Figure 3 As shown, the end face of the fixed platform 120 is provided with a mounting part 150, and an elastic sealing gasket 130 is arranged around the mounting part 150 on the end face of the fixed platform 120. The edge of the mounting part 150 is provided with a mounting groove for mounting signal pins 110.

[0026] like Figures 1 to 2 As shown, the female connector 200 has a waterproof pad 230 at the end opposite to the terminal block 210. The waterproof pad 230 has sealing holes arranged one-to-one with the terminal holes 211, and each sealing hole has an elastic puncture-type sealing layer 231. During assembly, the conductive wire harness used for electrical connection with the signal terminal passes through the waterproof pad 230 and can puncture the sealing layer 231 to connect with the signal terminal. After the puncture of the puncture-type sealing layer 231, it can form a seal with the surface of the wire harness, ensuring that the wire harness remains sealed after passing through the sealing hole. The puncture-type sealing layer 231 is made of rubber and has serrated surfaces, allowing the wire harness to puncture the sealing layer and form a seal. In addition, a sealing cover plate 240 fixed to the connector housing is provided on the outside of the waterproof pad 230, and the sealing cover plate 240 has positioning holes arranged one-to-one with the sealing holes. In this way, when the waterproof gasket is inserted into the female connector 200, the sealing cover 240 squeezes the waterproof gasket 230, causing the waterproof gasket 230 to be compressed to form an interference fit, which further improves the sealing effect and prevents water from entering the wire harness connection position; in addition, the edge of the sealing cover 240 and the end face of the female connector 200 are assembled through a snap-fit ​​structure, which ensures that the rear cover installation remains firm and stable.

[0027] like Figure 1 As shown, in this embodiment, a connecting fastener 250 is provided on the outer surface of the female connector 200 to engage and fix with the male connector 100. This ensures a stable connection between the female connector 200 and the male connector 100, preventing them from falling off, and also facilitates disassembly.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
