A high thermal change rate of test apparatus aims to realize test equipment requirement of highly accelerated life test(HALT) and highly accelerated stress screening(HASS). Structurally, the apparatus is provided with a cabinet body with an interior for placing test specimen. The cabinet body is provided with elements of fans, electric heating tubes and liquid nitrogen nozzles therein. The positions of the cabinet body and the control system are separate. Several groups (normally 2 or 3 groups, depends on the size of cabinet) of liquid nitrogen pipes connecting the cabinet body are flexible stainless steel pipes for enclosing and insulating sleeve tubes. During full-speed temperature cooling, all groups of the pipes simultaneously eject liquid nitrogen. When temperature is constant, only one group of liquid nitrogen pipe with cryogenic valve and nozzles is used and micro-adjusted to achieve good temperature stability. The cabinet body can match different types of shaker combinations to perform temperature/vibration test with high transition rate of temperature, and be used as a single high thermal change rate of temperature cabinet, can have relatively great assembly flexibility in response to test requirement. The entire apparatus has higher mobility and flexibility than conventional temperature/vibration cabinets.

The invention provides a flashlight lens, a housing assembly and a mobile terminal. The flashlight lens has a light-in surface and a light-out surface which is opposite to the light-in surface, and a circumferential side surface which is disposed between the light-in surface and a light-out surface. The light-in surface has flashlight rays come in, and the light-out surface has flashlight rays come out. The circumferential side surface is provided with a light blocking layer which blocks the flashlight rays. A light blocking layer which blocks the flashlight rays is disposed in the circumferential side surface of the flashlight lens, such that when flashlight rays enter the flashlight lens from the light-in surface, the light blocking layer blocks the light rays so as to prevent light rays from emitting from the circumferential side surface and light rays can be emitted from the light-out surface. The light blocking layer prevents leakage of flashlight rays, ensures photographing effects of a camera and improves user experience.
