A 3D flame retardant insulating end cover for a usbcan analyzer

Abstract

The invention discloses a 3D flame-retardant insulating end cover for a USBCAN analyzer. The USBCAN analyzer includes a metal shell, and a circuit board is embedded inside the metal shell. The top of the circuit board is fixed with a metal USB interface, a CAN terminal base, 2500V electrical isolation circuit, the bottom of the circuit board is fixed with protruding plug-in solder joints. Both ends of the metal shell are fixed with flame-retardant insulating end caps, and the top and bottom of one side of the flame-retardant insulating end cap are provided with plastic baffles. One side of the two plastic baffles is respectively connected to the top and bottom of the metal shell end contact connection. The present invention adopts the design of the flame-retardant insulating end cap, between the solder joints of the plug-in and the metal shell, surrounded by a 3D insulating baffle to prevent contact and tip discharge, thereby improving the isolation voltage level of the product; the design of the flame-retardant material effectively improves The safety and service life of the product are guaranteed; between the flame-retardant insulating end cover and the metal shell, the limit spring is used to push the limit post to be embedded in the card slot opened on the inner wall of the metal shell, which is convenient for the fixing of the flame-retardant insulating end cover and effectively avoids The looseness of the flame-retardant insulating end cap is prevented, and the stability of the product during use is improved.

Description

technical field [0001] The invention relates to a flame-retardant insulating end cap, in particular to a 3D flame-retardant insulating end cap for a USBCAN analyzer, belonging to the technical field of insulating end caps. Background technique [0002] At present, during the production process of USBCAN analyzer-related products, the two ends of the metal shell are generally packaged with stamped metal aluminum sheet end covers with low processing costs. Products using aluminum sheet end caps basically cannot pass the 2500V electrical isolation withstand voltage test. During the isolation withstand voltage test, the plug-in solder joint at the bottom of the circuit board discharges to the tip of the metal shell or the metal aluminum sheet end cover, the air gap is broken down, and the insulation resistance drops to 0 instantly. The isolation design is completely invalid and cannot be used in industry. occasions; and the metal USB interface on the PCB is in direct contact wi...
