Description

Signal transmission module and camera device {SIGNAL TRANSMISSION MODULE AND CAMERA APPARATUS}

The present invention relates to a signal transmission module and a camera device.

Nowadays, a camera device mounted on an electronic device such as a mobile phone takes an image using an image sensor.

Accordingly, recent camera devices include a lens unit to which a lens is mounted, an image sensor unit positioned in the lens unit and having an image sensor, and an image signal processing module for processing an image signal applied from the image sensor unit.

Such a camera device is provided with an anti-shake device and a position aligning device for adjusting the position of the lens unit to align the position or focus of the lens unit in order to prevent bad shooting due to external shock or hand shake during photographing.

Accordingly, a correction operation is performed to correct the positional deviation of the lens unit due to external impact, etc., and accurate alignment of the lens unit is performed.

In this case, the lens unit aligns the position of the lens unit by adjusting the position of the lens unit not only in the optical axis direction (ie, the lens mounting direction) but also in the direction intersecting the optical axis direction.

However, according to the alignment operation of the lens unit, the position of the signal transmission unit made of a flexible substrate that transmits the image signal output from the image sensor to the image signal processing module is also distorted according to the alignment of the lens unit.

Accordingly, there is a problem in that the signal transmission unit is damaged due to the distortion of the signal transmission unit due to the frequent positioning operation. Also, the connector part is located at both ends of the signal transmission unit for connection with other devices such as an image sensor. Damage to the connector may also occur.

In the inner space of the housing 10 formed by being surrounded by the first to third cases 11-13, the lens unit 20, the image sensor unit 30, and the signal transmission module 40 are provided, as already described. Located.

The lens unit 20 is located in the housing 10 and moves in the optical axis direction.

The lens unit 20 includes a lens assembly 21 having at least one lens and a lens driving unit 22 coupled to the lens assembly 21 to adjust the focus of the lens assembly 21 . If necessary, a lens housing 23 accommodating the lens assembly 21 and the lens driving unit 23 may be further provided.

Accordingly, the lens assembly 21 may move in the optical axis direction (eg, the vertical direction in FIG. 3 ) Y1 along the optical axis by the operation of the lens driving unit 22 to perform focus adjustment.

In addition, by controlling the tilting state of the lens assembly 21 and the housing 10 , alignment of the lens assembly 21 and the housing 10 in a horizontal direction (eg, a planar direction) may be performed. .

To this end, as shown in FIG. 1 as an example, the camera device of this example is positioned on the lens protrusion H11 of the housing 10 to align the lens unit 20 or the housing 10 in the horizontal direction. It may further include a position aligning unit (50).

The alignment unit 50 is coupled to the lens unit 20 to align the lens unit 20 in a first direction (eg, the first horizontal direction in FIG. 3 ) X1 of a pair of first alignment A pair of second alignment pins 52 coupled to the pin 51 and the housing 10 to align the housing 10 in the second direction (eg, the second horizontal direction in FIG. 3 ) (X2) can be provided.

Both the first horizontal direction X1 and the second horizontal direction X2 may cross the optical axis direction Y1 , and the first horizontal direction X1 and the second horizontal direction X2 may be orthogonal to each other.

The alignment pins 52 are each engaged with a corresponding portion of the adjacent housing 10 .

Therefore, by the driving device of the alignment unit 50 (not shown), the alignment unit 50 moves in the left and right directions around the first direction (X1) or the second direction (X2), that is, by tilting it. In addition to the lens unit 20 itself, the planar position of the housing 10 to which the lens unit 20 is coupled may be aligned.

By the tilting operation of the positioning unit 50 , the lens unit 20 and the housing 10 are aligned, so that an assembly error occurring during the assembly process of the camera device is corrected.

The alignment of the positions of the lens unit 20 and the housing 10 is already known, so a detailed description thereof will be omitted herein. In addition, it goes without saying that all structures for aligning the position of the camera device using other methods as well as the illustrated example are applied to the camera device of the present invention.

The image sensor unit 30 having an image sensor such as an imaging device (CCD) is coupled to the lens unit 20 and generates an image signal using light incident through the lens unit 20 .

The image sensor unit 30 is connected to the signal transmission module 40 as shown in FIGS. 1 and 3 and outputs the image signal generated through the signal transmission module 40 to an image signal processing module (not shown). will do

The lens unit 20 of the present example and the image sensor unit 30 coupled to the lens unit 20 may constitute a camera module of the camera device according to the present example. Accordingly, the camera module is located in the housing 10 and includes a lens unit 20 moving in the optical axis direction and an image sensor unit 30 coupled to the lens unit 20, and moving in a direction crossing the optical axis direction. Position alignment is done.

The signal transmission module 40, as shown in FIGS. 2 and 4, is a signal having at least one bending portion 411 that is bent at least once by changing the direction of extension to the opposite direction, that is, bending. The transmission unit 41, the buffer unit 42 located between the signal transmission unit 41 facing each other in opposite directions, at least one buffer unit located between the signal transmission unit 41 and the housing 10 ( 43) and a connector portion 44 for connection with other devices.

The connector unit 44 is positioned at both ends of the signal transmission unit 41 to perform electrical and physical connection with a corresponding device (eg, the image sensor unit 30 and the image signal processing module).

The signal transmission unit 41 has a flexible property, and as shown in FIG. 4 , it extends in the first extension direction D1 and then bends to the opposite of the first extension direction "?戮* second extension direction D2" can be extended to

Accordingly, the signal transfer unit 41 alternately extends in the first extension direction D1 and the second extension direction D2 without interruption, and as shown in FIG. 4 , the side surface of the signal transfer unit 41 has a plurality of sides. It has a structure in which the layers are stacked spaced apart along the vertical direction in a meandering form.

The signal transmission unit 41 may be formed of a flexible printed circuit board (FPCB, flexible printed circuit board (PCB)).

Although the drawing does not show signal lines or electrical and electronic devices located in the signal transmission unit 41 for convenience of illustration, in reality, the signal transmission unit 41 includes signal lines for input/output of signals or power supply and the operation of the camera device. Electrical and electronic devices for the purpose may be printed and mounted.

As described above, since the signal transmitting unit 41 of the signal transmitting module 40 has a structure that is bent to have at least one bending portion 411 to perform electrical and physical connection between the two devices, the position of the camera device Damage or breakage of the signal transmission unit 41 due to alignment is greatly reduced or reduced.

That is, when the tilting operation is performed to align the position of the camera device, the signal transmission module 40 also tilts in the corresponding direction by the tilting operation of the lens unit 20 to which the image sensor unit 30 is coupled. .

At this time, when the signal transmission unit is formed in a straight line extending in only one direction in a limited space in which the signal transmission module 40 is located, the torsional strength due to the tilting of the image sensor unit 30 is the signal transmission unit ( 41) is transmitted as a whole. Therefore, due to the distortion of the signal line or the electrical and electronic device located in the signal transmission unit 41, it adversely affects the connection state or the mounting state, and also damage or breakage of the connector unit 44 of the signal transmission module 40 occurs. . As a result, there is a problem in that a normal signal transmission is not made and a malfunction of the camera device occurs.

However, as in this example, when the signal transfer module 40 has a structure in which a plurality of layers are stacked by bending the signal transfer unit in a limited space in which the signal transfer module 40 is located, the length of the signal transfer unit 41 simply extends in one direction. will be much higher than it would have been. Accordingly, the torsional strength transmitted to the signal transmitting unit 41 due to the tilting of the image sensor unit 30 decreases in proportion to the increased length of the signal transmitting unit 41 . Accordingly, damage or breakage of the signal transmission unit 41 and signal lines or electrical and electronic devices positioned thereon is prevented or reduced.

In addition, since the twist strength applied to the connector part 41 of the signal transmission module 40 is also greatly weakened due to the increased length of the signal transmission unit 41 , compared to the case where the signal transmission unit is extended in only one direction, the corresponding device The degree of distortion and the strength of the connector part 41 for physical connection with the connector part 41 are also greatly reduced, so that damage to the connector part 41 is prevented or greatly reduced.

In addition, in the signal transmitting unit 41 of this example, as shown in FIG. 5 , the signal transmitting unit 41 is located at an edge portion adjacent to the connector unit 44 for coupling with a device such as the image sensor unit 30 . One slit portion SP41 having a slit H41 that is a plurality of openings formed by a predetermined length in the extension direction, that is, a plurality of openings located at both ends of the signal transmission unit 41 , respectively. A divided portion MAR40 having a groove P41 may be positioned. Accordingly, the signal transfer module 40 may further include at least one divided portion MAR40 positioned in the signal transfer unit 41 .

At this time, the portion in which the plurality of slits H41 are located is a portion located adjacent to the device that changes the position, such as distortion of the signal transmission unit 41, such as the image sensor unit 30, as described above. 41), it may be a front edge part or a rear edge part connected to the corresponding connector part 44 for coupling with another device such as the image sensor part 30 in the signal transmission part 41. .

Therefore, the slit H41 shown in FIG. 5 may be a false low-repulsion slit for reducing the repulsive force generated when the signal transmitting unit 41 is twisted.

The plurality of slits H41 are spaced apart along the width direction W41 intersecting the extending direction of the signal transmission unit 41, so that the area of the signal transmission unit 41 between the two adjacent slits H41 is separated from each other. there is. Accordingly, since the front edge portion of the signal transmission unit 41 includes the divided portion MAR40 including a plurality of divided areas AR41 divided by the slit H41 , the edge portion is disposed in the width direction W41 . The divided area AR41 and the slit H41 are alternately positioned along the .

In FIG. 5 , each slit H41 may have a rectangular planar shape extending in the extending direction of the signal transmitting unit 41 .

At this time, as shown in (a) of FIG. 5 , the edge of each slit H41 is completely surrounded and blocked by the open part of the signal transmission part 41 , that is, the divided area AR41, so that the divided part MAR40 ) as the center, the front part (ie, the part adjacent to the connector part 44) and the rear part located opposite to the front part may not have even a single slit H41. In this case, since each slit H41 is positioned only up to the adjacent connector part 44 , no slit H41 is positioned between the adjacent connector part 44 and the divided part MAR40 .

However, as shown in FIG. 5B , in another example, each slit H41 may be positioned until it comes into contact with the adjacent connector part 44 , and in this case, the slit in contact with the connector part 44 . A part of the edge of (H41) may be open.

In this example, the divided portion MAR40 including the plurality of divided areas AR41 and at least one slit H41 is located at the front edge portion.

However, in another example, at least one dividing portion MAR40 may be located not only in the front edge portion but also in another portion, that is, in the middle portion of the signal transmission unit 41 positioned between the front edge portion and the rear edge portion. can Here, the rear edge portion is an edge portion positioned opposite to the front edge portion, and may be an edge portion adjacent to the connector unit 44 connected to the image signal processing module.

In another example, at least one divided portion MAR40 may be positioned only in the middle portion.

Next, another example of the slit H41 positioned in the signal transmission unit 41 will be described with reference to FIG. 6 .

In the signal transmission unit 41 illustrated in FIG. 6 , a plurality of grooves P41 positioned at both edges extending along the extending direction of the signal transmission unit 41 are omitted for convenience of illustration.

As shown in FIG. 6 , the signal transmission unit 41 of this example has one edge (eg, a front edge) coupled to the image sensor unit 30 as an external device and the other edge (eg, a front edge) coupled to the connector unit 44 . The plurality of slits SP41a and SP41b are spaced apart from each other in the extending direction of the signal transmission unit 41 at predetermined intervals in the signal transmission part located between the rear edge).

In FIG. 5 , a plurality of slits H41 all having the same shape are positioned in the slit portion SP41 to be spaced apart from each other in the width direction W41 of the signal transmission unit 41 .

However, in the case of FIG. 6 , the slits SP41a and SP41b positioned in the extending direction of the signal transmission unit 41 include slits H41a and H41b having different shapes.

For example, the first slit portion SP41a having at least one first slit H41a and the second slit portion SP41b having at least one second slit H41b are alternately configured as signal transmitting units. (41) may be located.

Accordingly, the shapes of the slit H41a positioned in the first slit part SP41a and the slit H41b positioned in the second slit part SP41b may be different from each other.

In FIG. 6 , the number of slits H41a and H41b provided in each of the slit portions SP41a and SP41b may be one or more, and the shapes of the slits H41a and H41b provided in the same slit portions SP41a and SP41b are different from each other. may be the same.

Each of the second slit parts SP41b is positioned at each bending part 411 , and is an extension part other than the bending part 411 , for example, between the two adjacent bending parts 41 , the image sensor part 30 and the It may be located between the adjacent bending portions 41 or between the connector portion 44 and the adjacent bending portions 411 .

The width W411 of the first slit H41a of the first slit part SP41a positioned in the extended part and the second slit H41b of the second slit part SP41b may be the same, but the extended length L41a , L41b) may be different from each other. For example, the extended length L41a of the first slit H41a may be much longer than the extended length L41b of the second slit H41b.

Also, positions (ie, heights) in the width direction W41 at which the first slit H41a and the second slit H41b are located may be the same. That is, the positions of the first slit H41a and the second slit H41b immediately adjacent in the extending direction of the signal transmission unit 41 may be the same.

As described above, since the extension length of the first slit H41a positioned in the extended portion is much longer than that of the second slit H41b, resistance generated when the signal wiring unit 41 is twisted is greatly reduced, and thus the signal wiring unit 41 is ) is prevented from being damaged or damaged in the coupling part with the electrical and electronic device or other device 30 mounted on the device. Accordingly, the first slit H41a may be a slit for reducing a repulsive force generated during twisting.

In addition, the repulsive force applied to the bending portion 411 by the bending operation by the second slit H41a located in the bending portion 411 is dispersed through the second slit H41a so that a smooth bending operation is performed. By dispersing the resistance applied to the bending portion, a problem in which the signal transfer unit 41 is damaged in the bending portion 411 is reduced. Accordingly, the second slit H41b may be a slit for reducing a repulsive force generated during bending.

The number of the first slits H41a and H41b respectively provided in the first slit part SP41a and the second slit part SP41b is one or more as described above.

As shown in FIG. 6A , when the first slit part SP41a and the second slit part SP41b include one first slit H41a and one second slit H41b, one The positions of the first slit H41a and the one second slit H41b in the width direction may be the same as each other.

In addition, as shown in (b) and (c) of Figure 6, the first slit portion (SP41a) and the second slit portion (SP41b) is two or more first slits (H41a) and two or more second slits (H41b) , the width direction of the corresponding slits H41a and H41b positioned at the same (in order from one edge extending along the extending direction of the signal transmission unit 41) in each of the slits SP41a and SP41b. The positions may be the same as each other.

As described above, as shown in FIG. 6 , when the plurality of slits SP41a and SP41b are positioned along the extending direction of the signal transmitting unit 41 , the signal transmitting unit 41 may have one slit SP41a or SP41b. ) and a plurality of divided portions MAR40 having a plurality of grooves (not shown) may be provided.

5 and 6 , the tilting operation of the image sensor unit 30 is performed by the plurality of divided areas AR41 provided in each divided portion MAR40, that is, the plurality of slits H41, H41a, and H41b. The twisting force of the signal transmission unit 41 generated by the signal transmission unit 41 is greatly reduced and the effect of dispersion occurs.

That is, as already described, when the position of the image sensor unit 30 interlocked with the alignment operation of the lens unit 20 is changed, the signal transmission module 40 transmits the image sensor unit 30 through the connector unit 44 . ) and thus the position of the signal transmission module 40 in the same direction as the image sensor unit 30 also changes, resulting in twisting.

Accordingly, the torsional force transmitted from the image sensor unit 30 to the signal transmission unit 41 of the signal transmission module 40 in which wiring or electrical and electronic devices are located is directly transmitted to the left and right directions.

As such, when a twisting phenomenon occurs in the signal transmitting unit 41 , when the signal transmitting unit 41 is formed in the form of a film in which all openings are not located in the middle, the twisting force of the image sensor unit 30 is signal transmission It is applied to the whole of the part 41 as it is.

However, as in this example, when at least one divided portion MAR40 including a plurality of divided areas AR41 is located in the signal transmitting unit 41 positioned adjacent to the image sensor unit 30 , each divided area An empty space, which is an empty slit H41, H41a, H41b, is positioned between AR41. Accordingly, a dispersion effect and annihilation effect of the twisting force transmitted by the empty slits H41, H41a, and H41b or the repulsive force at the time of bending occur.

In addition, the signal transmission unit 41 for the twisting force transmitted to the signal transmission unit 41 by the empty slits H41 , H41a , H41b positioned in the middle of the signal transmission unit 41 and the repulsive force generated during bending of the signal transmission unit 41 . As resistance is reduced, flexibility with respect to a twisting operation is improved, and damage to the signal transmission unit 41 due to bending is reduced.

Due to this, the distortion degree and strength of the signal transmission unit 41 due to the twisting force of the image sensor unit 30 is greatly weakened, and damage to the signal transmission unit 41 as well as wiring and electrical and electronic devices located therein is greatly reduced. Breakage and poor contact are prevented or greatly reduced.

The plurality of grooves P41 located at at least one of both side ends of the signal transmitting unit 41 are located at corresponding side ends at predetermined intervals along the extending direction of the signal transmitting unit 41 .

At this time, when the grooves P41 are located at both side ends of the signal transmission unit 41, a pair of grooves P41 located at each side end in the opposite direction are identical to the same imaginary line drawn along the width direction W41. It may be positioned on the straight line L41 to face each other at different side ends [Fig. 5(a)], or may be deviated from different side ends [Fig. 5(b)].

As such, by the plurality of grooves P41 positioned at both ends of the signal transmission unit 41 extending in the extending direction of the signal transmission unit 41, the twisting force of the signal transmission unit 41 is further dispersed. and the resistance of the signal transfer unit 41 is further reduced.

The groove P41 may be located in at least one of the divided portion MAR40 and the middle portion.

However, if necessary, the groove P41 may be omitted.

Next, another example of the divided portion MAR40a positioned in the signal transfer unit 41 will be described with reference to FIG. 7 .

As shown in FIG. 7 , the divided portion MAR40a includes a divided area EAR41 that is a plurality of protruding areas that protrude from the front edge of the signal transmitting unit 41 toward the image sensor 30 and extend.

At this time, since the divided areas EAR41 are spaced apart from each other along the width direction W41 of the signal front end part 41 , slits H41 and H41a are also formed between the divided areas EAR41 adjacent in the width direction W41 . Located. However, as already described, since each divided area EAR41 of this example is a protruding area protruding in a desired direction, the slits H41 and H41a of this example are the slits H41 and H41 shown in FIGS. H41a), a portion (ie, the front end or the rear end), that is, the portion in the protruding direction is open.

This divided region EAR41 is directly bonded to the connection portion of the image sensor unit 30 without going through a separate connector unit 44 , thereby physically and electrically connecting the image sensor unit 30 and the signal transmitting unit 41 to each other. It can also serve as a connector that connects to In this case, the signal transmission unit 41 including the divided portion MAR40a may be formed of a rigid flexible printed circuit board (RFPCB).

The signal transmission unit 41 illustrated in FIG. 7 may also include the groove P41 illustrated in FIGS. 5A and 5B in at least one of the dividing portion MAR40a and the middle portion.

As such, when the divided portion MAR40a for protecting the signal transmitting unit 41 due to the distortion of the signal transmitting unit 41 includes a plurality of divided regions EAR41 , the connector portion 44 is additionally Since it is unnecessary to use, the problem of poor contact or damage to the signal transmission unit 41 occurring in the connection portion between the image sensor unit 30 and the connector unit 44 is solved. In addition, an increase in the volume of the signal transmission module 40 due to the connector part 41 is greatly reduced and the manufacturing of the signal transmission module 40 is also easily effected.

Referring back to FIG. 4 , as described above, the signal transmission module 40 having the bending portion 411 caused by at least one bending operation includes two types of buffering portions 42 and 43 .

Hereinafter, the buffer layer 43 located between the housing 10 and the signal transmission unit 41 is referred to as a 'first buffer unit', and the buffer unit 42 located between two adjacent signal transmission units 41 . is called a 'second buffer unit'.

Among these two buffers (42, 43) will be described first from the second buffer (42).

The second buffer 42 may be positioned between the signal transfer units 41 facing each other in opposite directions to space the adjacent signal transfer units 41 apart.

This second buffer portion 42 may be located adjacent to the bending portion 411, but is limited thereto. Therefore, when the second buffering part 42 is located adjacent to the bending part 411, one side of the second buffering part 42 is surrounded by the bending part 411, and the other side facing the one side is to be opened. can

The second buffering part 42 is a pair of buffering members 421 and 422 respectively located on the inner surface of the signal transmitting part 41 located in layers adjacent to each other facing each other in opposite directions (eg, in the vertical direction). ) is provided. As shown in Figure 6, the corresponding portion (L42a) of the signal transmission unit 41 in which the buffer layer members (421, 422) are located has a larger width (L42b) than the other portions, the buffer members (421, 422) It can facilitate mounting and increase adhesion. At this time, the pair of first cushioning members 421 and 422 have the same structure except that only the positioned portions (the inner lower surface and the inner upper surface of the bending portion 411) are different.

The buffer members 421 and 422 of the present example may include an elastic material such as silicone or a sponge, or may have an elastic structure.

As an example, the buffer members 421 and 422 may have a plate shape, such as a hexahedral structure, such as a cuboid having an elastic material.

Accordingly, the signal transfer unit 41 facing each other on the opposite side in the bending portion 411 is spaced apart from each other by more than the total thickness of the two cushioning members 421 and 422 forming a pair.

For this reason, even if the position or bending shape of the signal transmission unit 41 is changed due to the twisting phenomenon of the signal transmission module 40, the spacing between the bending portions 411 by the pair of buffer members 421 and 422 is constant. Keep more than spacing. Accordingly, a problem in which the signal transfer unit 41 is damaged or damaged in the bending portion 411 is prevented.

In addition, even if the signal transmission unit 41 fluctuates due to torsion or shake in the vertical direction of the signal transmission module 40, the signal transmission unit ( 421 , and 422 ) is positioned in opposite directions and collided with each other. 41), the applied force is absorbed and dispersed. Accordingly, the impact applied to the signal transmission unit 41 is reduced to protect not only the signal transmission unit 41 but also the signal lines and electrical and electronic devices positioned in the signal transmission unit 41 .

In addition, the signal transmission module 40 is further protected from external force by the at least one first buffering unit 43 .

That is, each of the first buffering units 43 is located between the signal transmitting unit 41 and the signal transmitting unit 41 and a portion of the housing 10 adjacent to the signal transmitting unit 41 due to shaking of the signal transmitting unit (41). 41) is protected.

In this example, the first buffer 43 is between the signal transmission unit 41 and the inner surface of the upper surface 112 of the first case 11 of the housing 10 and the signal transmission unit 41 and the housing 10 . It may be located between the inner surface of the lower surface 131 of the third case 13 of the

At this time, the position of the signal transfer unit 41 in which each first buffer unit 43 is located may be adjacent to the bending portion 411 in which the pair of second buffer units 42 are located.

Accordingly, as shown in FIG. 4 , when two bending parts 411 are present in the signal transmission unit 41 , two first buffer units 43 are present.

Accordingly, one first buffer part 43 is located on the lower surface 131 of the third case 13 of the housing 10 or the corresponding part (eg, the bending part 411) of the signal transmitting part 41 lower surface It may be positioned between the bending portion 411 and the lower surface 131 of the third case 13 of the housing 10 .

In addition, the remaining first buffering unit 43 is located on the corresponding portion of the signal transmitting unit 41, for example, on the remaining bending portion 411 or on the inner surface of the upper surface 112 of the first case 11, the corresponding bending It may be positioned between the portion 411 and the upper surface 112 of the first case 11 of the housing 10 .

The plurality of first buffering parts 43 all have the same structure, and absorb the impact applied to the outside by providing an elastic material or an elastic structure.

Examples of the structure of such a first buffer unit 43 are shown in FIGS. 8 and 9 .

First, as shown in (a) of Figure 8, the first buffer portion 43 is at least one protrusion 432 protruding upward from the upper surface of the body 431 and the body 431 made of a buffer material. can be provided.

Both the body 431 and the protrusion 432 may include an elastic material.

The body 431 may have a plate shape such as a hexahedron, such as a rectangular parallelepiped, and the protrusion 432 may protrude from the upper surface of the body 431 toward the adjacent signal transmission unit 41 .

In Figure 8 (a), the projection 432 is made of a plurality of spaced apart along the extending direction of the body 431, but is not limited thereto and may be formed of one.

The first buffering part 43 is positioned so that the protrusion 432 is adjacent to or in contact with the adjacent signal transmission part 41 .

Accordingly, as shown in FIG. 4 , the lower surface of the body 431 of the first buffer part 43 positioned on the bending part 411 positioned adjacent to the third case 13 is the third case 13 . The lower surface of the body 431 is located in contact with the lower surface 131 and the first buffer part 43 positioned in the bending portion 411 positioned adjacent to the first case 11 has a lower surface of the first case 11 . It may be positioned in contact with the inner surface of the upper surface 112 .

At this time, the lower surface of the body 431 of the first buffer unit 43 is applied to the corresponding surface (that is, the lower surface 131 of the third case 13 or the upper surface 112 of the first case 11). It can be attached using

The protrusion 432 of the first buffering unit 43 may be in contact with the corresponding portion of the signal transmitting unit 41 or may be adjacently spaced apart.

However, the present invention is not limited thereto, and in an alternative example, the first buffer part 43 may include only the body 411 or a plurality of protrusions 432 arranged to be spaced apart in the corresponding direction.

As another example, as shown in Figure 8 (b), the first buffer 43 is made of an elastic member such as a spring (spring) such as a plate spring (plate spring) or coil spring (coil spring) corresponding It may be attached to the surfaces 112 and 131 . As such, when the first buffering part 43 is made of an elastic member, the first buffering part 43 is located on the inner surface of the adjacent housing 10 and protrudes toward the adjacent signal transmission part.

After the second armband 43 as shown in FIG. 8 is manufactured as a separate component, it may be separately attached to the mounting portion by using an adhesive or soldering process. Accordingly, the first buffer 43 may be made of a component separate from the components 11 and 13 to which they are attached.

However, the first buffer part 43 of this example can be manufactured integrally with the parts 11 and 13 by seamlessly connecting the parts 11 and 13 to be mounted thereon.

In this case, the first buffering part 43 may be formed of a protruding part protruding from the corresponding cases 11 and 13 in the corresponding direction and having an elastic force.

To this end, as shown in FIG. 9 , the first buffer part 43 may be a protrusion formed by cutting the case portion located at the corresponding position of the case 11 and 13 and then bending it in the corresponding direction. In this case, the openings H43 are generated in the cases 11 and 13 by the cutting operation. Therefore, the opening H43 generated by the formation of the first buffer part 43 is covered with a separate insulating film or insulating plate, etc. to prevent the inflow of foreign substances such as dust or moisture into the signal transmission module 50 . there is.

However, the first buffer 43 may be a protrusion that is integrally manufactured with the corresponding cases 11 and 13 and protrudes from the corresponding position in the corresponding direction. In this case, a separate opening due to the formation of the first buffer part 43 does not occur in the corresponding cases 11 and 13 .

As described above, since the signal transmission module 40 of this example includes the divided parts EAR40 and EAR40a having a plurality of divided areas AR41 and EAR41, the dispersion effect of the torsional force transmitted from the image sensor unit 30 is is improved, and resistance to torsional force is greatly reduced, so that the torsional strength of the signal transmission unit 41 is greatly weakened.

In addition, the resistance to the twisting operation of the signal transmitting unit 41 is further reduced by the plurality of grooves P41 positioned at both ends of the signal transmitting unit 41, and the dispersion effect of the torsional force is further increased.

In addition to this, in addition to the second buffer unit 42, a first buffer unit 43 positioned between the signal transmission unit 41 and the corresponding cases 11 and 13 is additionally provided.

Accordingly, when the position of the lens unit 20 and the housing 10 are aligned by the first buffer unit 43 , the position of the image sensor unit 30 coupled to the lens unit 20 is changed, resulting in a signal Even if the signal transmission unit 41 of the transmission module 40 shakes or twists in the vertical or horizontal direction, a phenomenon in which the signal transmission unit 41 directly collides with the adjacent housing 10 is prevented.

The bending part 411, which is heavier than other parts due to the mounting of the second buffer part 42, has a higher degree of shaking or distortion than other parts due to the weight, so the probability of colliding with the adjacent housing 10 is high, and the housing 10 ), the impact applied to the bending portion 411 and the housing 10 when colliding with it is much greater than that of other parts.

However, when the first buffering part 43 is positioned between the bending part 411 on which the second buffering part 42 is mounted and the corresponding housing 10 part, the bending part 41 is attached to the housing 10 . Instead of colliding directly, it collides with the second cushioning part 43 , so that the impact applied to the housing 10 and the bending part 41 is greatly alleviated.

In particular, as shown in Figure 7 (a), when the first buffer part 43 is provided with a plurality of protrusions 432 that protrude from the body 411 and are spaced apart from each other, it is transferred to the first buffer part 43 The impact is improved due to the protrusions 422 spaced apart from each other. Accordingly, the size of the impact transmitted to the corresponding housing 10 portion is further reduced.

In the above, embodiments of the signal transmission module and the camera device of the present invention have been described. The present invention is not limited to the above-described embodiments and the accompanying drawings, and various modifications and variations will be possible from the point of view of those of ordinary skill in the art to which the present invention pertains. Accordingly, the scope of the present invention should be defined not only by the claims of the present specification, but also by those claims and their equivalents.
