Description

Camera lens module testing socket

The present invention relates to a camera lens module test socket, and more particularly, to a camera lens module test socket, which is composed of a cam plate and a bushing so as to be in line contact with three sides of a camera lens module to improve the life of the pogo pin, To a camera lens module test socket.

Generally, a small-sized camera is mounted on a mobile communication terminal to capture and store moving images and images. Such a small-sized camera is equipped with a CMOS or CCD image sensor on a printed circuit board, and is assembled in a lens and a housing, And is connected to a flexible printed circuit board.

Most of the recent mobile communication terminals are provided with cameras, and most of the cameras use CMOS or miniature cameras to which a CCD image sensor is applied. In addition, these compact cameras are equipped with a VCM module for autofocus and camera shake correction.

Conventional motor-type actuators have difficulty in precisely controlling a fine focus because they move the lens mechanically, and in particular, it is difficult to miniaturize a camera due to space limitation in incorporating a motor and a gear into a camera.

A voice coil module (VCM) has been developed to improve the mechanical actuator having such a problem. The voice coil module (VCM) is an actuator that linearly moves the lens using the Lorentz force generated by the induction magnetic force of the coil in the magnetic field of the permanent magnet, and is suitable for a camera system that performs a linear motion with a relatively short distance.

The compact camera is equipped with a CMOS or CCD image sensor on a printed circuit board, then assembled into a VCM module including a lens and a housing, and then electrically connected to a flexible printed circuit board for electrical communication with the outside The camera assembly is manufactured, and then it is inspected whether or not the manufactured camera module is normally operated.

In general, the voice coil module (VCM) must be evenly focused on the entire screen in the state of being assembled with the camera module together with the image sensor. Especially, when the slope between the lens assembled in the VCM and the reference surface at the bottom of the VCM is exactly horizontal, the focus is uniformly generated.

However, in the actual assembly process, since the flatness of the coated surface of the lens surface is not constant even if the lens is not mounted at the correct position due to twisting of the leaf spring of the VCM or the lens is correctly mounted, .

Such bad VCM occurs in many high-resolution auto-focus camera modules, but the four corners of the photographed image do not coincide with the focus of the center, causing out-focusing to one side, leading to a failure of the auto-focus camera module itself.

However, if the VCM module is defective when the inspection is performed after the manufacture by the camera assembly, the entire assembly becomes defective. Therefore, a test socket for checking whether the VCM module is operating normally before the image sensor is installed is needed.

In order to solve this problem, Korean Patent No. 10-1448961 proposes a socket for inspecting the VCM module for checking normal operation of the VCM module before assembling the camera assembly, as shown in FIG.

The socket for inspecting a VCM module according to the related art includes a base plate 2 on which the VCM module 1 is seated, an inner cover plate 3 hinged to the base plate 2, An outer cover plate 4 connected to the inner cover plate 3 and maintaining a state in which the inner cover plate 3 is protruded at a predetermined angle by an elastic force and a VCM module 1 And a slider 5 having a connection pin 4a corresponding to the terminal of the slider 5a.

The slider 5 has an inclined surface and the outer cover plate 4 has a protrusion 3a for pressing the inclined surface so that the protrusion 3a presses the inclined surface, 4a are connected to the terminals of the VCM module 1.

This prior art socket for inspecting a camera module has a problem in that the structure is complicated and the parts are consumed in duplicate.
