The present invention relates to a camera module inspection socket device. More particularly, the signal of a camera module mounted on a base body is drawn out to the outside of a pivoting body through a connecting board of a soft material and is separately connected to the main board by a connector method, Even if the test is carried out by repeating the folding body several thousands times and the folding body is repeatedly used, the damage due to the repeated contact of the connecting terminal is not generated. Therefore, even if the camera is used for a long time, And it is not necessary to secure a lower area of the base body mounted on the main board as a separate area. Therefore, it is possible to improve the degree of freedom in circuit design by using the area as various circuit design areas, A car that can increase the range of It relates to a module called test socket device.

Recently, smartphones and other devices have been released in the form of a camera, so it is now possible to shoot still images and movies by smart phones. Currently, cameras are almost essential in smart phones, and these cameras are gradually improving the performance of cameras for high-resolution and high-quality shooting.

The camera module mounted on the smartphone will be operated separately for the camera module separately from the operation test for the smartphone before shipment. Specifically, the open / short test, the resistance value measurement of the power line, , Input / output leakage current inspection, and the like.

In addition, the camera module must perform fixed focusing, image inspection, and AF drive test to determine the fastening depth by precisely rotating the lens part to fit the sensor and housing part and a specific fixed focal distance before shipment. The focus adjustment operation is a process for inspecting a fixed focus of a lens. Image inspection is a process for inspecting whether a defect of unit pixels in a sensor, defects such as scratches or particles is present, by precisely analyzing an output image of a camera module, The inspection is a process for checking whether the auto-focusing function that operates by activating a driving unit such as a VCM or the like of the camera module has an operation error.

In order to perform various inspections of the camera module, a camera module inspecting socket device is generally provided for inspecting the camera module while inserting and fixing the camera module.

1 is a view schematically showing a configuration of a conventional camera module testing socket device according to the prior art.

The conventional camera module inspecting socket device according to the related art includes a main board 40 that can be connected to a separate test computer (not shown) and a test socket TS that is seated on the upper surface of the main board 40 do.

The test socket TS includes a base body 20 mounted on the upper surface of the main board 40 and having a module seating portion 21 formed on the upper surface thereof for seating the camera module 10, The camera module 10 is mounted on the module mounting part 21 in contact with the upper surface of the base body 200 in a rotatably folded state, And a rotating body 30 in which the connecting pin terminal 32 is protruded and mounted. The connection pin terminal 32 is coupled to the connection pin block 31 protruding from the contact surface of the rotary body 30 so that one end of the connection pin terminal 32 protrudes outward in the form of a pogo pin.

A separate auxiliary board 33 is mounted inside the pivot body 30 so that the other end of the connection pin terminal 32 is contactably connected. The auxiliary connection terminal 34 is formed at one side of the auxiliary board 33 so that the signal transmitted from the module terminal 11 of the camera module 10 is transmitted to the auxiliary connection terminal 34 And is connected through the pattern circuit of the auxiliary substrate 33 and the auxiliary connection terminal 34. A main connection terminal 22 is connected to the base body 20 such that the main connection terminal 22 protrudes outwardly in the form of a pogo pin so as to be in contact with the auxiliary connection terminal 34. The main board signal terminal 41 is formed on the main board 40 so as to be in contact with the main connection terminal 22 of the base body 20.

The connecting pin terminal 32 of the rotating body 30 is rotated by the rotation of the base body 20 while the camera module 10 is seated on the module mounting portion 21, Is brought into contact with the module terminal 11 of the camera module 10. The module terminal 11 of the camera module 10 is connected to the auxiliary substrate 33 and the auxiliary connection terminal 34 via the connection pin terminal 32. [ Since the auxiliary connecting terminal 34 and the main connecting terminal 22 are in contact with each other as the pivot body 30 rotates and folds on the base body 20, Signal is transmitted to the main connection terminal 22 through the auxiliary connection terminal 34 and is transferred from the main connection terminal 22 to the main board signal terminal 41 and the main board 40. The signal transmitted to the main board 40 is transmitted to a computer for inspection (not shown) through a separate signal cable (not shown), analyzes signals of the camera module 10 transmitted through the computer for inspection, (10).

That is, a signal transmitted from the module terminal 11 of the camera module 10 is transmitted to the auxiliary board 33 of the pivot block 30 through the connection pin terminal 32, Is transferred to the main board 40 through the main board 34 and the main connection terminal 22 and is transferred from the main board 40 to a separate inspection computer.

According to this structure, in addition to the connection pin terminal 32 contacting the module terminal 11 of the camera module 10, the auxiliary connection terminal 34 and the main connection terminal 34 22 are repeatedly brought into pressure contact with each other. Therefore, if the inspection work for the camera module is repeated thousands of times, the auxiliary connecting terminal 34 and the main connecting terminal 22 are pressed and abutted in the same manner at the same point several thousands times in the same manner, There arises a problem that the plating site formed on the substrate 34 is peeled or damaged.

Particularly, the auxiliary connection terminal 34 and the main connection terminal 22 relatively strengthen the pogo pin elastic force of the main connection terminal 22 for the sake of signal transmission stability, The more easily the damage occurs.

If the auxiliary connection terminal 34 is damaged as described above, the inspection socket device must be replaced. In this case, since the inspection process must be interrupted and the replacement process must be performed, a problem that the process speed is reduced and the efficiency is lowered have. The loss of such a process has a very negative effect on the process speed, since the inspection socket device is usually replaced two or three times a day in one inspection process line.

Since the main board signal terminal 41 connected to the main connection terminal 22 of the base body 20 must be formed on the main board 40, The main substrate signal terminal 41 and the pattern circuits connected thereto must be formed in a region located at the lower portion of the main substrate 40. Accordingly, the freedom of circuit design of the main substrate 40 is reduced, There is a problem such that there is a limit to miniaturization of the device.

The camera module inspecting socket device according to an embodiment of the present invention is constructed such that the contact between the base body 200 and the pivoting body 300 is removed and the contact damage is prevented even if the contact is used for a long time, A main body 100, a base body 200, a rotating body 300, and a connecting board 400. [

The main board 100 is connected to a separate inspection computer (not shown) to transmit an operation signal to the camera module 10 from an inspection computer, as well as a video signal generated by the operation of the camera module 10, Signals, etc. to a computer for inspection, and performs functions such as power supply and control of overall operation.

The base body 200 is mounted on the upper surface of the main board 100 and the module mounting part 210 is formed on the upper surface to mount the camera module 10 thereon. The module seating part 210 is formed to be fixed to a certain degree in a state where the camera module 10 is seated in the form of a concave groove. Of course, the camera module (0 is pressed and fixed by the rotating body 300 as the rotating body 300 is folded in a state where the camera module (0 is seated on the module mounting portion 210).

The rotating body 300 is coupled to the base body 200 so as to be rotatable and foldable. The camera module 10 is mounted on the module seating portion 210 on a contact surface, which is in contact with the upper surface of the base body 200, The connection pin terminal 311 is protruded and mounted so as to be brought into contact with the module terminal 11 of the module board 11. The connection pin terminal 311 may be formed in the form of a pogo pin that is inserted into a separate connection pin block 310 and elastically protruded.

2, an opening / closing sensing terminal 230 is formed in the concave groove 22, and the opening / closing sensing terminal 230 is formed in the concave groove 22, The opening / closing contact terminal 320 may protrude from one side of the contact surface to contact the opening / closing sensing terminal 230 of the concave groove 220 as the rotating body 300 rotates and is folded on the base body 200. A separate fine power source is supplied to the open / close detection terminal 230 through the main board 100. When a signal generated as the open / close contact terminal 320 contacts the open / close detection terminal 230 is supplied to a separate controller The control unit may receive the signal and transmit the test power and operation signal to the camera module 10 from the inspection computer. According to this configuration, whether or not the rotation body 300 is pivotally folded on the base body 200 can be known, and the test power source and operation signal for the camera module 10 can be detected only when the pivot body 300 is pivotally rotated It is possible to perform the inspection operation stably without damaging the camera module 10 which is an actual mass production product. That is, after the connection pin terminal 311 of the rotation body 300 is connected to the module terminal 11 of the camera module 10, the test power and the operation signal are transmitted to the module terminal 10 of the camera module 10 11 and the connection pin terminal 311 can be prevented from being sparked and the module terminal 11 of the camera module 10 can be prevented from being damaged.

The connection board 400 is fixedly coupled to the outer surface of the rotary body 300 opposite to the contact surface, and the connection terminal 411 is formed at one side thereof in contact with the connection pin terminal 311. The connection board 400 is formed of a flexible material and one end of the connection board 400 extends to the outside of the rotation body 300 and is connected to the main board 100.

The camera module 10 mounted on the module mounting part 210 of the base body 200 transmits and receives signals to and from the main board 100 through the connecting board 400 in a state where the rotating body 300 is rotated and folded, .

A main connector 110 is formed on one side of the main board 100 and a connection connector 440 is formed on one end of the connection board 400 so as to be fastened and connected to the main connector 110, The connection connector 440 is connected to the main board 100 as it is fastened to the main connector 110.

According to the above configuration, the camera module testing socket device according to the embodiment of the present invention draws the signal of the camera module 10 to the outside of the rotating body 300 through the connecting board 400 made of a soft material, 100), a separate connection terminal (22, 34 in FIG. 1) for signal transmission is unnecessary between the base body 200 and the rotary body 300, unlike the prior art, Even if the body 300 is repeatedly folded and repeated several thousands of times, the contact of the separate connection terminals 22 and 34 does not occur, so that the connection terminal for contact does not occur, Module inspection can be performed.

More specifically, the connection board 400 includes a coupling fixture 410, which is in contact with the outer surface of the rotary body 300 and has a connection terminal 411 connected to the connection pin terminal 311 at one side, And an extension part 420 extending from one end of the joint fixing part 410 to be drawn out to the outside of the rotation body 300 and having a connection connector 440 to be fastened to the main connector 110 at an end thereof, . The joint fixing part 410 and the extension part 420 may be integrally formed of a flexible printed circuit board (FPCB).

Since the end of the extension part 420 of the connection board 400 is drawn out to the outside of the rotation body 300 and connected to the main board 100, the connection board 400 can be rotated independently of the folding of the rotation body 300. [ Even if the rotating body 300 is repeatedly rotated and folded for the test of the camera module 10, the terminals are not repeatedly contacted. Therefore, in the repeated testing process, The signal transmission / reception with respect to the module 10 is continuously and stably performed.

A separate insulating support plate 430 is joined to the outer surface of the connection fixing part 410 of the connection board 400 so as to support the connection fixing part 410, And is coupled to the rotation body 300 together with the joint fixing part 410 in a state of being joined to the rotation part 410. The joint fixing part 410 of the connection board 400 is stably supported and fixed by the insulating support plate 430 in a state of being coupled to the rotation body 300 and the extension part 420 is fixed to the rotation body 300, So that it is possible to stably maintain the state of connection with the main board 100. In addition,

The outer surface of the pivot body 300 is formed with a concave depressed engagement groove portion 301 and a state in which the joint fixing portion 410 of the connection board 400 and the insulation support plate 430 are bonded to each other The insulating support plate 430 may be inserted into and engaged with the coupling groove 301 of the rotary body 300 with the coupling portion 410 of the connection board 400 interposed therebetween. The method of tightly coupling may be performed through a separate coupling screw as shown in FIG. In this manner, the connecting board 400 is coupled to the outer surface of the turning body 300 together with the insulating supporting plate 430, so that the assembling operation of the connecting board 400 can be performed more easily.

The coupling groove portion 301 of the turning body 300 is provided with a guide protruding outwardly so as to guide the insertion and insertion position of the insulating support plate 430 joined to the coupling and fixing portion 410 of the connection board 400. [ A protrusion 330 may be formed and a guide hole 402 may be formed in the coupling and fixing part 410 and the insulation support plate 430 of the connection board 400 so that the insertion hole may be inserted into the guide protrusion 330. Since the connection terminal 400 is connected to the connection pin terminal 311 in a state where the connection board 400 is coupled to the rotation body 300, The connection position of the connection substrate 400 can be guided through the connection hole 402 and the connection substrate 400 can be coupled to the correct position.

The connection substrate 400 may be manufactured by forming a pattern circuit on each of the two base films 401. The connection fixing portion 410 of the connection substrate 400 includes two base portions 401, The extension portions 420 may be formed in a separated form in which the two base films 401 extending from the engagement fixing portions 410 are not bonded to each other. 5 and 6, the arrangement (curvature or the like) of the extending portion 420 is repeatedly deformed in the rotating folding process of the pivoting body 300. At this time, the two base films 401 When the two base films 401 are formed in a separated form from each other as in the embodiment of the present invention, the flexibility is reduced and the fatigue is accumulated due to the repetition of deformation, , The flexibility of each base film 401 is maintained, and even if deformation is repeated, damage or breakage does not easily occur.

5, when the camera module 10 is mounted on the module mount 10 in the camera module 10 according to the present invention, The connecting pin terminal 311 is contactably connected to the module terminal 11 of the camera module 10 when the rotating body 300 is rotated and folded as shown in FIG. The connection board 400 is connected to the connection pin terminal 311 through the connection terminal 411. The connection board 400 is drawn out to the outside through the extension part 420 and is connected to the main board 100). That is, the signal generated from the module terminal 11 of the camera module 10 is transmitted to the connection board 400 through the connection pin terminal 311, and is transmitted through the extension part 420 of the connection board 400, (300) and transferred to the main substrate (100).

Therefore, a separate connection terminal for signal transmission is unnecessary between the pivoting body 300 and the base body 200, so that damage due to repeated contact of the terminal does not occur, durability is improved, signal transmission is stable, Since a separate terminal for signal transmission to the main board 100 is not required in the lower part of the body 200, the lower area of the base body 200 can be utilized freely, have.
