Description

Elastic sheet contact type lens IR-CUT

Technical Field

The utility model relates to a camera field, concretely relates to shell fragment contact lens IR-CUT.

Background

The IR-CUT double-filter means that a group of filters are arranged in a camera lens group, and when infrared sensing points outside the camera lens detect the change of the intensity of light rays, the built-in IR-CUT automatic switching filters can automatically switch according to the intensity of external light rays, so that the image achieves the best effect. That is, the dual filter can automatically switch the filters in the daytime or at night, and thus the best imaging effect can be obtained regardless of the daytime or at night.

As shown in fig. 6, the conventional lens IR-CUT generally adopts a connection manner of driving coils: there is 2PIN terminal lines and adds a terminal male head, female seat to the terminal of inserting on the mainboard. The existing connection mode makes the integral composite part complex, and a driving coil, a terminal male head and a terminal female seat are required to be used, so that the production cost is increased; meanwhile, terminal wires need to be inserted in the production process, and the production efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

To the above shortcoming that prior art exists, the utility model provides a shell fragment contact lens IR-CUT can effectively overcome the synthetic part that prior art exists complicacy, the lower defect of production efficiency.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the IR-CUT comprises an infrared filter lens and a PCB, wherein a connecting column is relatively fixed on the side surface of the infrared filter lens, a first threaded hole is formed in the connecting column, a second threaded hole is formed in the position, opposite to the first threaded hole, on the PCB, a metal elastic sheet is electrically connected to the bottom of the infrared filter lens, and a copper exposure contact point is arranged in the position, opposite to the metal elastic sheet, on the PCB.

Preferably, the connecting column is fixedly connected with the second threaded hole through a fixing bolt.

Preferably, the metal elastic sheet is in a barb shape.

(III) advantageous effects

Compared with the prior art, the utility model provides a shell fragment contact camera lens IR-CUT adopts the synthetic contact mode of exposing the copper contact point on metal shrapnel and the PCB board, has replaced the connected mode of the public head of traditional terminal and the female seat grafting of terminal, directly accomplishes the contact with metal shrapnel, has simplified synthetic part, effectively improves production efficiency, has saved the process flow of pendulum terminal line and plug terminal line simultaneously, has reduced manufacturing cost.
