When the closure 600 is pressed by the cover 700, the second closing part 710 is inserted into the cable housing part 500 as the second slope part 621 is guided by the first slope part 520. That is, the second slope part 621 can perform a function of inserting the first closing part 710 into the cable accommodating part 500.

The second hole 510 of the cable housing part 500 can be completely closed by the first closing part 610. Therefore, the camera module 1000 of the present embodiment can maintain airtightness.

Hereinafter, the closure 600 of the present embodiment will be described with reference to fig. 4, 5 and 6. The closure 600 may have elasticity. For example, the material of closure 600 may be synthetic rubber. The closure 600 may have a hollow cylindrical shape having different cross-sectional areas in the vertical direction. The third hole 611 may be formed at the center of the closure 600 and penetrate the closure 600 in the vertical direction. The third hole 611 may be coaxially disposed with the second hole 510 of the cable housing part 500. The cable 800 may be disposed inside the cover 600.

In this case, the cable 800 can pass (penetrate) through the closure 600 via the third hole 611. The third hole 611 and the cable 800 may be coaxially disposed. The closure 600 may include a first closure portion 610 and a second closure portion 620.

The first closing part 610 may function to close the cable housing part 500 to maintain airtightness within the camera module 1000. The first closing part 610 may be disposed inside the cable accommodation part 500. The first closing part 610 may be in the form of a hollow cylinder. The third hole 611 may be formed on an inner side of the first closing part 610 and vertically penetrate the first closing part 610. The first closure 610 is capable of receiving the cable 800.

The upper surface of the enclosure portion 610 may contact the plate 310 of the second outer member 300. The outer surface of the first closing part 610 may contact the inner surface of the cable accommodating part 500. The first closing part 610 may include a plurality of rings 612 spaced apart from each other in an axial direction (vertical direction), and an outer diameter of the plurality of rings 612 is greater than an inner diameter of the cable receiving part 500. That is, the first closing part 610 may have the same shape as the bellows (below). The first closing part 610 can press the inner surface of the cable accommodating part 500 through the plurality of rings 612 to completely seal the inner surface.

The second closing part 620 is pressed by the cover 700 to guide the first closing part 610 to the inside (second hole) of the cable containing part 500, and clamps (clasping) the cable 800 to fix the cable 800. The second closing part 620 may be provided on one side (lower side) of the cable housing part 500. The second closing part 620 may be exposed to the outside of the cable accommodating part 500. The second closing part 620 may extend in a direction (lower direction) in which the cable housing part 600 extends in the first closing part 610. The second closing part 620 may have a cylindrical shape having different diameters in a vertical direction. A third hole 611 penetrating the second closing part 620 in a vertical direction may be formed on an inner side of the second closing part 620. The second closure 620 can accommodate the cable 800. The second closing part 620 can be accommodated in the cover 700. The second closing part 620 may include a second slope part 621 and a third slope part 622.

The second slope 621 may be in the form of a tapered tube having the third hole 611 formed at the center thereof. The second inclined part 621 may be provided at one side (lower side) of the first inclined part 520 of the cable receiving part 500. An upper surface of the second slope part 621 may face a lower surface of the first slope part 520. The second slope part 621 may contact the first slope part 520. The second slope part 621 extends in a direction in which the cable housing part 500 extends (in a direction in which the cable housing part extends) at one end of the first closing part 610, and may be inclined outward (radially outward) toward the extending direction of the cable housing part 500. Since the inclination of the second inclined part 621 and the first inclined part 520 is the same, if the closure 600 is pressed upward by the cover 700, the second inclined part 621 can be guided along the first inclined part 520. Such a guiding action of the second slope part 621 can push the first closing part 610 into the inside of the cable accommodating part 500, thereby allowing the cable accommodating part 500 to be completely closed.

The third slope part 622 may be in the form of a tapered tube having a third hole 611 formed at the center thereof. The third inclined part 622 may be disposed on one side (lower side) of the second inclined part 621. The third inclined part 622 extends in a direction in which the cable housing part 500 extends (a direction in which the cable housing part 500 extends) at one end of the second inclined part 621, and the third inclined part 622 is inclined inward (radially inward) toward the extending direction (downward) of the cable housing part 500.

Hereinafter, an arrangement structure of the third slope part 622 and the cover 700 will be described with reference to fig. 5 and 6. An outer surface of the third inclined part 622 may be disposed to be opposite to an inner surface of the fourth inclined part 730 of the cover 700. The outer surface of the third inclined part 622 can contact the inner surface of the fourth inclined part 730.

The cap 700 presses the closure 600 upward, and at least a part of the pressing force acts inward (radially inward) by the inclination directions of the third and fourth inclined portions 622 and 730. As a result, the second closing portion 620 can fix the cable 800 by clamping the cable 800, as if the cable 800 were gripped (ripping).

The third inclined portion 622 may be inclined in the same direction as the fourth inclined portion 730, but the inward (radially inward) inclination angle of the third inclined portion 622 may be greater than the inward inclination angle of the fourth inclined portion 730. That is, the width of the upper portion of the third inclined portion 622 (see the oblique line) may be greater than the width of the upper portion of the cover 700. The third inclined portion 622 can be further urged inward (radially inward) than the case where the inclination angles of the third inclined portion 622 and the fourth inclined portion 730 are the same. As a result, in the present embodiment, the fixing effect of cable 800 can be improved.

Hereinafter, the cover 700 of the present embodiment will be described with reference to fig. 4, 5, and 6. The cover 700 may be provided on one side (lower side) of the second outer member 300. The cover 700 may be disposed on the lower surface of the plate 310. The cover 700 can accommodate the cable accommodation part 500 and the closure 600. The cover 700 may be brought into close contact with the closure 600 to press the closure 600. The cover 700 may include a base portion 710, an intermediate portion 720, a,

A fourth inclined portion 730, and a penetrating surface 740.

A fourth hole 711 penetrating the cover 700 may be formed at the center of the cover 700 in a vertical direction. The fourth hole 711 may be formed through the base 710, the middle portion 720, the fourth inclined portion 730, and the penetrating surface 740. Thus, the cover 700 may be hollow. The cross-sectional area of the fourth hole 711 may become smaller as it goes toward one side (lower side). The fourth hole 711 may be provided coaxially with the third hole 611 of the closure 600.

The base 710 may be provided to contact the outer surface of the second external member 300 in the form of a flat plate. The upper surface of the base 710 and the lower surface of the plate 310 can contact each other. The locking protrusion 712 may be formed on the upper surface of the base 710. The locking protrusions 712 may be two. The two locking protrusions 712 may be symmetrically disposed with respect to the central axis of the fourth hole 711. Each of the two locking protrusions 712 can be received in each of the two locking grooves 312. The cover 700 can be firmly fixed to the second outer member 300 by receiving the locking protrusion 712 in the locking groove 312.

The middle portion 720 may be in the form of a hollow cylinder. The middle portion 720 may be disposed at one side of the base portion 710 (downward in the direction in which the cable receiving portion extends). The intermediate portion 720 may extend in the direction (one side, lower side) in which the cable housing portion 500 extends in the base portion 710. The cable accommodation part 500 may be disposed inside the middle part 720. The cable accommodation part 500 may be disposed in the fourth hole 711 of the middle part 720.

The inner surface of the middle portion 720 can contact the outer surface of the cable housing portion 500. The middle portion 720 is disposed inside and may include a second threaded portion 721 in the form of a three-dimensional spiral. The second threaded part 721 can be threadedly coupled into the first threaded part 620 of the cable receiving part 600. The cover 700 is moved upward to press the closure 600 according to the screw coupling of the second screw part 721 and the first screw part 620

The middle portion 720 may include a plurality of ribs 722, the plurality of ribs 722 being circumferentially spaced apart from each other and connecting the outer circumferential surface of the middle portion 720 to the base portion 710. The plurality of ribs 722 may have a right triangle shape in which two sides other than the hypotenuse are in contact with the outer circumferential surfaces of the base portion 710 and the middle portion 720, respectively. The plurality of ribs 722 support the middle portion 720 against wobbling.

The fourth inclined part 730 may be in the form of a tapered tube having a fourth hole 711 formed at the center thereof. The fourth inclined portion 730 may be disposed at one side of the middle portion 720 (downward in a direction in which the cable receiving portion extends). The fourth inclined portion 730 may extend in a direction (one side, downward) in which the cable housing portion 600 extends (downward in the direction in which the cable housing portion extends) at one end of the middle portion 720. The fourth inclined portion 730 may be inclined inward (radially inward) toward a direction (one side, lower side) in which the cable receiving portion 600 extends. The fourth inclined portion 730 can contact the third inclined portion 622 of the closure 600. The fourth inclined portion 730 may be inclined inward (radially inward) at an angle greater than the angle at which the third inclined portion 622 is inclined inward.

When the cap 700 presses the closure 600 upward by the inclination direction of the fourth inclined portion 730, the fourth inclined portion 730 can press the third inclined portion 622 not only toward the upper side but also toward the inner side (radially inner side). As a result, the second closure 620 can clamp the cable 800 as if the cable 800 were manually grasped.

The penetrating surface 740 may be in the form of a flat plate having a fourth hole 711 formed at the center thereof. The penetrating surface 740 may be provided at one end (in the direction in which the cable receiving part extends) of the fourth inclined part 730. The cable 800 may extend through the through surface 740 and to the exterior of the second outer member 300.

The cable 800 may be a wire electrically connecting the electronic element section 400 to an external electronic device (e.g., a power supply device, an electronic control unit, a display unit, etc.). Cable 800 can electrically connect the substrate of substrate portion 410 and an external electronic device.

The cable 800 may extend to the outside of the second outer member 300 by passing through the second outer member 300, the closure 600, and the cover 700 in this order from the electronic component part 400. The cable 800 may pass through (penetrate) the board 310, the first closing portion 610, the second closing portion 620, and the penetrating surface 740 in the electronic element portion 400 in this order, respectively, and extend to the outside of the second exterior member 300. In this case, the cable 800 can pass through (penetrate) the first hole 411, the third hole 611, and the fourth hole 711 in this order.

The upper end of the cable 800 may be mounted on the connector 440. Connector 440 may be mounted on the substrate of substrate portion 410 to electrically connect cable 800 with the substrate of substrate portion 410. Connector 440 may be electrically connected to the substrate of substrate section 410 through connection substrate 450 to electrically connect cable 800 with the substrate of substrate section 410.

The middle portion of the cable 800 may be disposed inside the enclosure 600 through the first hole 411. The cable 800 may be fixed by the second closing part 620 so as not to swing. The middle portion of the cable 800 may extend to the outside of the second outer member 300 through the fourth hole 711.

The lower end of the cable 800 may be electrically connected to external electronic devices (e.g., a power supply device, an electronic control unit, and a display unit). The camera module 1000 can receive power from a power supply device through the cable 800. The camera module 1000 can receive an electronic control signal from the electronic control unit via the cable 800. The camera module 1000 can transmit an image signal output from the image sensor 420 to the display unit via the cable 800.
