Projector lamp switch protection structure

Abstract

A light bulb switch protection structure of a projector includes a casing, a casing, a switch and an elastic sheet. There is a mounting hole on the shell; the shell is accommodated in the shell; the switch is set on the shell and pierced through the mounting hole. The switch includes a switch body and a metal shrapnel fixedly connected to the switch body at one end. The metal shrapnel controls the power supply of the switch Or disconnect; one end of the elastic sheet is fixed on the housing, and the other end elastically abuts against the end of the metal elastic sheet away from the switch body, and the metal elastic sheet is located between the elastic sheet and the switch body, so that the elastic sheet blocks the metal elastic sheet. The light bulb switch protection structure of the projector can prevent the metal shrapnel on the switch from being knocked off.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a protective structure for a light bulb switch of a projector. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. However, due to safety requirements, when removing the bulb cover of the projector, it is necessary to ensure that the projector is in a power-off state, usually a metal shrapnel is set on the switch, and when the metal shrapnel contacts the contact on the switch, it is in power supply state, when the metal shrapnel leaves the contact, it is in a power-off state; because the metal shrapnel is generally relatively small, when the bulb cover is installed, the bulb cover is directly pressed on the metal shrapnel, that is, in the process of production assembly and ...

Problems solved by technology

However, due to safety requirements, when removing the bulb cover of the projector, it is necessary to ensure that the projector is in a power-off state, usually a metal shrapnel is set on the switch, and when the metal shrapnel contacts the contact on the switch, it is in power supply state, when the metal shrapnel leaves the contact, it is in a power-off state; because the metal shrapnel is generally relatively small, when the bulb cover is installed, the bulb cover is directly pressed on the metal shrapnel, that is, in the process of production assembly and subsequent replacement of the bulb assembly In the process, the entire metal shrapnel is exposed and easily knocked off, resulting in frequent replacement of the light bulb switch, which brings inconvenience to both production and use
