In this case, be coupled to the device coupling unit 125 of image sensering device 121, one end is connected to the connector 127 of external substrate and is formed at first signal transmission component 124 from the coupled outside part 126 of installing coupling unit 125 extensions and stretch out from image sensering device 121 outsides.Therefore, be different from traditional camera module 10 (Fig. 1), secondary signal transfer element 134 is not directly to be electrically connected to external substrate.But, secondary signal transfer element 134 is coupled to first signal transmission component 124, thereby the coupled outside part 126 through first signal transmission component 124 is electrically connected AF module 130 to external substrate, and this has eliminated the demand of AF module 130 and 120 pairs of independent connectors of image sensor module.
Therefore, external substrate does not need to supply independent signal or power to AF module 130 and image sensor module 120, thereby reduces the size of camera model 100 and reduce because the loss of signal that causing appears in noise.
In this case, shown in Figure 4 and 5, the first pattern exposure unit 129 is formed at first signal transmission component 124, and the second pattern exposure unit 139 that contacts the first pattern exposure unit 129 is formed on the secondary signal transfer element 134.In this case, first and second signal transmission components 124 and 134 can be by coupling, and as securing member, bonding agent or other coupling device well known in the art are electrically connected.As can be appreciated, if first and second signal transmission components 124 and 134 are FPCB, first and second signal transmission components 124 and 134 can not comprise, each 124a of basic unit and 134a that forms by polyimide or polymkeric substance for example, each circuit pattern 124b and 134b of on 124a of basic unit and 134a surface, forming, and each insulation course 124c and 134c of on circuit pattern 124b and 134b, forming. Partial circuit pattern 124b and 134b that the first and second pattern exposure unit 129,139 expose under it.
The first pattern exposure unit 129 can extend formation on the coupling unit 128.In this case, coupled outside part 126 is extended from an end of device coupling unit 125, stretch out farly from image sensering device 121, and extend coupling unit 128 and can in the opposite direction extend out to coupled outside part 126 from the other end of image sensering device 121 and be placed.
In this case, shown in Figure 4 and 5, coupling aperture 123 and 133 is formed at the extension coupling unit 128 and the secondary signal transfer element 134 of first signal transmission component 124 respectively.Coupling element 140 can be coupled by the coupling aperture 123 and 133 that passes alignment first and second signal transmission components 124 and 134.
Just, the secondary signal transfer element 134 of AF module 130 is around a side of AF box 131, and to the extension of the top of AF box 131, this AF box 131 puts the AF device.Image sensor module 120 is installed in the top of AF box 131 in the mode that does not hinder secondary signal transfer element 134, and extends coupling unit 128 and be positioned in and secondary signal transfer element 134 contact positions.In this case, extend the top that coupling unit 128 is positioned in secondary signal transfer element 134, first and second signal transmission components 124 and 134 overlap and contact with each other here.In addition, coupling aperture 123 and 133 forms at an end that extends coupling unit 128 and corresponding secondary signal transfer element 134 respectively.Coupling element 140 passes coupling aperture 123 and 133, thereby is coupled first and second signal transmission components 124 and 134.

Such example of structure is as follows.Protrusion element 132 is formed on the AF box 131 of vicinity corresponding to the top surface in the zone of coupling aperture 123 and 133.Therefore, the screw as coupling element 140 inserts and receives and be fixed in the protrusion element 132 by hole 123,133.Further as shown in the figure, packing ring 144 can be placed in screw and extends between the coupling unit 128.
In order to make the camera model 100 with said structure, at first, first signal transmission component 124 is positioned in a side of image sensering device 121.In this case, first signal transmission component 124 comprises the device coupling unit 125 that is coupled to image sensering device 121, extend and leave the coupled outside part 126 of image sensering device 121, and leave the extension coupling unit 128 of image sensering device 121 to the place that coupled outside part 126 is placed to the relative direction extension with the contact external substrate.And circuit pattern 124b exposes in the zone of the bottom of extending coupling unit 128, and this zone will contact with secondary signal transfer element 134.
With image sensering device 121 together, AF module 130 is manufactured.As shown in Figure 3, AF module 130 comprises secondary signal transfer element 134.Secondary signal transfer element 134 is coupled to the extension coupling unit 128 of first signal transmission component 124 and round the part of the sidewall of AF module 130.Passive device 143 can be placed in the bottom of secondary signal transfer element 134.In this case, the circuit pattern 134b of exposure is arranged in the zone of extending coupling unit 128 corresponding to the top surface of secondary signal transfer element 134.
Then, image sensor module 120 and AF module 130 are coupled to together.At this moment, contact with circuit pattern 134b at the circuit pattern 124b of the exposure at first signal transmission component, 124 places of image sensor module 120 in the exposure at secondary signal transfer element 134 places of AF module 130.Just, the sweep that extends coupling unit 128 and secondary signal transfer element 134 contacts with each other, and extends coupling unit 128 at the top, and secondary signal transfer element 134 overlaps at this base section 128,138 in the bottom.And extension coupling unit 128 and secondary signal transfer element 134 are electrically connected and are coupled through coupling element 140.
In other embodiments, the first and second pattern exposure unit 129 and 139 surface can directly engage but not by coupling element 140 couplings they.In this mode, can improve the electrical connection between the first and second pattern exposure unit 129 and 139.
Therefore, provide the camera model according to second embodiment of the invention, it does not need Fig. 3 to arrive coupling element shown in Figure 5 140.With reference to figure 6 to Fig. 8, camera model 200 comprises first signal transmission component 224 with first pattern exposure unit 229 and the secondary signal transfer element 234 that can comprise the second pattern exposure unit 239.As can be from seeing Fig. 8, the first and second pattern exposure unit 229 and 239 be such zones, and wherein circuit pattern 224b and 234b expose on first and second signal transmission components 224 and 234.Further, bonding agent 254 is positioned between the first and second pattern exposure unit 229 and 239, thereby is electrically connected the first and second pattern exposure unit 229 and 239 and each circuit pattern 224b, 234b.
In this case, first signal transmission component 224 can comprise coupled outside part 126, device coupling unit 125 and extension coupling unit 228.Coupled outside part 126 is stretched out to leave image sensering device 121 at first direction from the end extension of device coupling unit 125.Extension coupling unit 228 can leave image sensering device 121 and stretch out on the direction relative with first direction.In this case, the first pattern exposure unit 229 can be placed in and extends coupling unit 228.
