3D flame-retardant insulating end cover for USBCAN analyzer

Abstract

The invention discloses a 3D flame-retardant insulating end cover for a USBCAN analyzer. The 3D flame-retardant insulating end cover comprises a metal shell, a circuit board is embedded in the metal shell, a metal USB interface, a CAN wiring terminal base and a 2500V electrical isolation circuit are fixedly arranged at the top end of the circuit board, and protruding plug-in welding spots are fixedly arranged at the bottom end of the circuit board. Flame-retardant insulating end covers are fixedly arranged at the two ends of the metal shell, plastic baffles are arranged at the tops and the bottoms of one sides of the flame-retardant insulating end covers, and one sides of the two plastic baffles are in contact connection with the top end and the bottom end of the interior of the metal shell correspondingly. Through the design of the flame-retardant insulating end cover, the 3D insulating baffle is used for full surrounding and blocking between the plug-in welding spot and the metal shell to prevent contact and point discharge, so that the isolation voltage grade of the product is improved; due to the design of the flame-retardant material, the safety and the service life of the product are effectively improved; and limiting columns are pushed by limiting springs to be embedded in clamping grooves formed in the inner wall of the metal shell, so that the flame-retardant insulating end cover is convenient to fix, loosening of the flame-retardant insulating end cover is effectively avoided, and the stability of the product in the using process 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...
