A description is primarily given below of the differences between the image pick-up module 10 a and the image pick-up module 10. Unless stated otherwise, the description of the image pick-up module 10 applies to the image pick-up module 10 a.
Although the circuit board 26 a of the image pick-up module 10 a is again of integral and single-part design like the circuit board 26, it has, in contrast to the circuit board 26, the shape of a U. The circuit board 26 a correspondingly has a groove 60 which extends between two longitudinal sides 36 a and 38 a and is open on the longitudinal sides 36 a and 38 a.
Electronic components 42 a and 42′a are arranged in the depression formed by the groove 60, to be precise in a three-dimensional arrangement, that is to say the components 42 a and 42′a are arranged in the groove 60 such that they are stacked on top of one another, as described in DE 10 2004 056 946 A1, reference being made to that document as regards further details.
The cores 46 a and 48 a of the flexible multi-core cable 44 a are contact-connected on the closed longitudinal sides 34 a at contact-connection points 50 a which are closer to the image sensor 12 a than the underside 30 a of the circuit board 26 a. The contact fingers 16 a and 18 a of the image sensor 12 a extend along the open longitudinal sides 36 a and 38 a of the circuit board 26 a and their ends 58 a are contact-connected on the underside 30 a of the circuit board 26 a.
FIG. 3 shows another exemplary embodiment of an image pick-up module 10 b which has been modified further in comparison with the exemplary embodiments in FIGS. 1 and 2. Parts of the image pick-up module 10 b which are the same as or comparable to the corresponding parts of the image pick-up module 10 are provided with the same reference symbols supplemented by the letter b.
In the exemplary embodiment shown, both individual circuit boards 62 and 64 respectively accommodate one or more electronic components 42 b, 42′b (individual circuit board 62) and 42″b (individual circuit board 64). In contrast to the circuit board 26 a in which the components 42 a, 42′a are arranged in the groove 60 of the circuit board 26 a such that they are stacked on top of one another, the components 42 b, 42′b and 42″b are respectively accommodated only in a “two-dimensional” arrangement in the individual circuit boards 62 and 64. The components 42 b, 42′b and 42″b can thus be respectively mounted and contact-connected on a base 66 and 68 of the individual circuit boards 62, 64, as a result of which assembly of the individual circuit boards 62, 64 with the components 42 b, 42′b, 42″b is easier than assembly of the circuit board 26 a with the components 42 a, 42′a.
The contact fingers 16 b and 18 b of the image sensor 12 b are contact-connected on an underside 30 b of the circuit board 26 b, more precisely of the individual circuit board 64, which is remote from the image sensor 12 b. The contact fingers 16 b, 18 b thus engage over the longitudinal sides 36 b and 38 b of the individual circuit boards 62, 64 and can be used, in particular, to hold the individual circuit boards 62 and 64 together.
As a further difference to the image pick-up module 10 or 10 a, the circuit board 26 b of the image pick-up module 10 b has separate depressions 54 b and 56 b for each of the cores 46 b, 48 b.
FIG. 4 shows another exemplary embodiment of an image pick-up module 10 c, parts of the image pick-up module 10 c which are the same as or comparable to corresponding parts of the image pick-up module 10 being provided with the same reference symbols supplemented by the letter c.
The image pick-up module 10 c has a circuit board 26 c which, like the image pick-up module 10 b, is formed from two individual circuit boards 70, 72, both individual circuit boards 70, 72 being of U-shaped design. In this case too, a configuration with blind holes or the like may also be considered instead of a U-shaped configuration of the individual circuit boards 70, 72. It goes without saying that the grooves of the individual circuit boards may also be oriented in a manner rotated through 90° with respect to one another instead of being parallel to one another.
In contrast to the circuit board 26 b, the individual circuit board 72, that is to say the last individual circuit board as seen from the image sensor 12 c, assumes the function of contact-connecting the multi-core cable 44 c. The cores of the multi-core cable 44 c are contact-connected to the circuit board 26 c, more precisely to the individual circuit board 72, but not on an underside 30 c of the individual circuit board 72 which is remote from the image sensor 12 c, as is the case in the image pick-up module according to DE 10 2004 056 946 A1, but rather on a side 74 facing the image sensor 12 c. In this case, the cores of the cable 44 c are guided through the individual circuit board 72 from the side 30 c to the side 74, with the result that the contact-connection points 50 c are closer to the image sensor 12 c than the underside 30 c. This also again results in the fact that the direct junction between the cable 44 c and the underside 30 c of the circuit board 26 c is flexible at the point 52 c.
Whereas only the individual circuit board 70 according to FIG. 4 b) has been provided with electronic components 42 c, 42′c, the individual circuit board 72 can also additionally accommodate such electronic components in its groove-like depression 76, however.
For the rest, the image pick-up module 10 c corresponds to the image pick-up module 10 b.
A further modification of the image pick-up module 10 b in FIG. 3 is shown in FIG. 5 in the form of an image pick-up module 10 d. Parts of the image pick-up module 10 d which are the same as or comparable to corresponding parts of the image pick-up module 10 are provided with the same reference symbols supplemented by the letter d.
The individual circuit board 80, that is to say the last individual circuit board as seen from the image sensor 12 d, is used as the cable terminal for contact-connecting the cores of the cable 44 d. In contrast to the preceding exemplary embodiment, the individual circuit board 80 has a section 82 having longitudinal sides 84, 86, 88, 90, at least one of which, or all of which in the exemplary embodiment shown, is/are smaller than the longitudinal sides 32 d, 34 d, 36 d, 38 d of the remaining part of the circuit board 26 d, with the result that the section 82 has a smaller cross-sectional dimension than the remaining part of the circuit board 26 d and the image sensor 12 d.
At least one of the longitudinal sides 84, 86, 88 and 90, or all of the longitudinal sides in the exemplary embodiment shown, is/are used to contact-connect the cores of the cable 44 d, the contact-connection points 50 d being at a distance from the underside 30 d which is remote from the image sensor 12 d in the direction of the image sensor 12 d in this case too.
In the exemplary embodiment of the image pick-up module 110 shown, the circuit board 114 is of integral or single-part design in a manner comparable to the circuit board 26 or 26 a. The circuit board 114 is arranged parallel to the image sensor 112 and has a length, as seen in the longitudinal direction, of approximately half the length of the circuit board 26 or 26 a.
In contrast to the circuit board 26 or 26 a, the circuit board 114 is at a distance d from the image sensor 112, more precisely from the basic body 124 of the latter, with the result that a free space 126 is present between the basic body 124 of the image sensor 112 and the circuit board 114, which space may optionally be filled with a curable filling composition which is electrically insulating. At least one electronic component 128 is arranged on the circuit board 114 and is electrically contact-connected to the latter in the space between the image sensor 112 and the circuit board 114.
The cores 136 a and 138 a of the multi-core cable 140 a are again guided through the circuit board 114 a through holes 134 a and are contact-connected to the circuit board 114 a on a top side 132 a.
In comparison with the previous exemplary embodiment, the cores 136 a and 138 a are guided through the circuit board 114 a to such an extent that their sheaths, in particular screens 150 and 152, protrude from the top side 132 a of the circuit board 114 a, the exposed ends 154 and 156 being bent through 180° from the longitudinal direction and their outermost ends being electrically contact-connected to the circuit board 114 a on the top side 132 a.
It goes without saying that electrical components may also be arranged on the top side 132 a of the circuit board 114 a and may be contact-connected to the circuit board 114 a.
FIGS. 9 and 10 illustrate two further modifications of the image pick-up module 110.
FIGS. 9 a) and b) show an image pick-up module 110 b having the main components of an image sensor 112 b, a circuit board 114 b and a flexible multi-core cable 140 b.
In contrast to the circuit board 114 or 114 a, the circuit board 114 b is of multi-part construction.
The circuit board 114 b has a rigid base board 158 whose function in this case is to contact-connect cores 136 b of a multi-core flexible cable 140 b. The cores 136 b are again preferably guided through holes (not illustrated in any more detail) from the underside 130 b to the top side 132 b of the base board 158 and are contact-connected to the base board 158 on the top side 132 b.
The base board 158 preferably does not have any electronic components. Rather, in order to accommodate electronic components, the circuit board 114 b has at least one further circuit board part 160 which is flexibly connected to the base board 158, to be precise by means of conductors or conductor tracks 162. The further circuit board part 160 is in the form of a thin plate and extends perpendicular to the image sensor 112 b in the space between the base board 158 and the image sensor 112 b.
The circuit board part 160 extends approximately in the form of an extension of a longitudinal side 164 of the image sensor 112 a or the basic body 124 a of the latter and may have, on its inner side (not illustrated), one or more electronic components which are electrically contact-connected to the circuit board part 160. A further circuit board part of this type may also be arranged parallel to the circuit board part 160 on the opposite longitudinal side.
The circuit board parts 166 and 168 are used, inter alia, to partially enclose the multi-core cable 140 b but without impairing the flexibility of the cable 140 b.
FIGS. 10 a) and b) illustrate a modification of the image pick-up module 110 b in the form of an image pick-up module 110 c. Parts of the image pick-up module 110 c which are the same as or comparable to corresponding parts of the image pick-up module 110 are provided with the same reference symbols supplemented by the letter c.
The image pick-up module 110 c has a circuit board 114 c which, like in the previous exemplary embodiment, has a base board 174, two circuit board parts 176, 178 which lead from the base board 174 to the proximal end transversely to the image sensor 112 c, and a circuit board part 180 which leads away from the base board 174 to the distal end and extends transversely to the image sensor 112 c.
The circuit board part 180 has a first section 182 and a second section 184 which adjoins the latter, the sections 182 and 184 running perpendicular to one another and being connected to one another in an electrically conductive and flexible manner, the section 182 extending perpendicular to the base board 174 and the section 184 extending parallel to the base board and parallel to the image sensor 112 c.
Electronic components may be contact-connected both to the section 182 and to the section 184.
5. The image pick-up module of claim 1, wherein said image sensor has a plurality of contact fingers that are arranged in at least one row, and said contact fingers of said image sensor are contact-connected on at least one longitudinal side of said circuit board on which elongate contacts which are arranged so as to be recessed are provided.
