The attachment part 1 includes: a base portion 10, holding pieces 21 to 23 provided in the base portion 10; and a projection portion 30 provided in the base portion 10. The attachment part 1 is integrally made of a synthetic resin. The holding pieces 21 to 23 extend from a front surface 12 of the base portion 10 in the substantially identical direction. The holding pieces 21 to 23 face each other. The projection portion 30 extends downwardly from a bottom surface of the base portion 10. The holding pieces 21 to 23 serve as holding portions. The holding pieces 21 to 23 sandwich the optical component to apply even pressures on its chassis. The projection portion 30 serves to attach the attachment part 1 to a printed substrate. The base portion 10 has a through hole 14 through which a lead of the optical component, to be mentioned later, is capable of passing. The through hole 14 has a slit shape horizontally spreading from the front surface 12 to a rear surface 13.
The holding pieces 21 to 23 are spaced apart from each other with a given clearance, and entirely shape a substantially circular cone. The holding pieces 21 to 23 are elastically deformable to move their ends toward and away from each other. FIGS. 1A and 1B illustrate a natural state of the holding pieces 21 to 23.
Herein, the optical component will be described. FIG. 2 is an explanatory view of the optical component. As illustrated in FIG. 2, there are optical components 90 to 90 c having different shapes. Two leads 94 to 94 c extend from lower ends of chassis 92 to 92 c, respectively. The leads 94 to 94 c ensure the electrical connection between the printed substrate, to be mentioned later, and the optical components 90 to 90 c, respectively. In the optical components 90 to 90 c, the distances of the leads 94 to 94 c are different from each other. The chassis 92 to 92 c each has a substantially cylindrical shape. An optical fiber, not illustrated, is attached on each of upper ends of the chassis 92 to 92 c.
Next, a description will be given of the attachment of the optical component on the printed substrate. FIGS. 3A to 3D, 4A, and 4B are explanatory views of the attachment of the optical component on the printed substrate. The attachment of an optical component 90 a will be described. FIG. 3A illustrates a cross section of the attachment part 1. The through hole 14 passes through the base portion 10 from the front surface 12 to the rear surface 13. The holding pieces 21 to 23 are closer to each other from the base portion 10 side toward their ends, when they do not sandwich the optical component. As illustrated in FIG. 3B, the optical component 90 a is inserted into the holding pieces 21 to 23 against their elastic restoring forces. When the optical component 90 a is inserted into the holding pieces 21 to 23, the holding pieces 21 to 23 are deformed to move their ends away from each other. The leads 94 are inserted into the through hole 14.
As illustrated in FIG. 3C, when the optical component 90 a is inserted to reach the base portion 10 side, a lower surface of the optical component 90 a comes into contact with the front surface 12. In this state, the optical component 90 a is held by the elastic restoring forces of the holding pieces 21 to 23. In this manner, the optical component 90 a is attachable to the attachment part 1 with ease. Specifically, the holding pieces 21 to 23 sandwich an outer periphery of an axis of an chassis 92 a of the optical component 90 a. Therefore, the attachment part 1 prevents the optical component 90 a from rattling in the direction perpendicular to its axial direction.
In this state, when the base portion 10 is pushed upwardly and downwardly, the through hole 14 is crushed to be compressively deformed such that leads 94 a are sandwiched thereby. While the leads 94 a are sandwiched by the through hole 14, the optical component 90 a is prevented from being displaced in its axial direction with respect to the attachment part 1. Additionally, the reason why the through hole 14 is shaped to have a slit shape is to facilitate deforming the through hole 14 to be crushed.
Next, as illustrated in FIG. 3D, the leads 94 a extending from the through hole 14 are bent downwardly along the rear surface 13. At the time of bending, the leads 94 a are bent along the rear surface 13 at a corner portion, where the rear surface 13 and the inner surface of the through hole 14 are intersected. The rear surface 13 corresponds to a definition surface for defining an angle of the bending of the lead 94 a. This facilitates the workability of bending the leads 94 a. Further, the base portion 10 has the corner portion for facilitating bending of the leads 94 a passing through the through hole 14. This also improves the workability.
Further, the leads 94 a are bent along the rear surface 13 with the chassis 92 a being in contact with the front surface 12, thereby preventing the optical component 90 a from being displaced in its axial direction with respect to the base portion 10. That is, the chassis 92 a abuts the front surface 12, and the bent portion of the lead 94 a abuts the corner portion of the base portion 10, thereby defining the position of the optical component 90 a with respect to the base portion 10. Accordingly, the optical component 90 a is prevented from rattling in its axial direction.
FIG. 3D illustrates the rear surface 13 of the base portion 10 after leads 94 a are bent. The rear surface 13 is provided with two groove portions 16 separating two leads 94 a from each other. The groove portions 16 extend vertically. The leads 94 a are respectively accommodated in the groove portions 16, thereby preventing the leads 94 a from contacting and short-circuiting each other. Additionally, an insulated tube does not have to be attached to one of the leads 94 a to prevent short circuit. This improves the workability.
Next, as illustrated in FIGS. 4A and 4B, the attachment part 1 is attached to a printed substrate 80. The projection portion 30 and the leads 94 a are inserted into an attachment hole 83 and through holes 84 formed in the printed substrate 80, respectively. The projection portion 30, to be described later in more detail, has an end with a flange shape, thereby engaging the projection portion 30 with the printed substrate 80 after the projection portion 30 is inserted into the attachment hole 83. Thus, the lower surface of the base portion 10 is brought into contact with the upper surface of the printed substrate 80, thereby supporting the attachment part 1. Next, the leads 94 a and the printed substrate 80 are soldered. In this way, the optical component 90 a is attached on the printed substrate 80.
Consequently, the optical component can be attached to the attachment part 1, and the attachment part 1 attached with the optical component can be also attached to the printed substrate. This improves the workability of the attachment. Further, since the optical component 90 a is held by the holding pieces 21 to 23, a fastening fluctuation which may not be caused as seen in a case where an operator manually fastens the optical component to the attachment part by use of the band. This prevents the optical component from being broken caused by a too strong fastening force. This also prevents the optical component from rattling caused by a too weak fastening force.
Next, a description will be given of a state in which the optical component 90 c is attached to the attachment part 1. FIGS. 5A and 5B are explanatory views of the state in which the optical component 90 c is attached to the attachment part 1. The chassis 92 c of the optical component 90 c has a diameter larger than that of the chassis 92 to 92 b. Since the holding pieces 21 to 23 are elastically deformable to move away from each other, the attachment part 1 is capable of holding the optical component 90 c as illustrated in FIG. 5A. In this way, the attachment part 1 is capable of attaching the optical component with a different size. Additionally, the distance between the leads 94 c of the optical component 90 c is larger than that between the leads 94 a. In this way, the width of the groove portions 16 is applicable to the optical component having a different distance between the leads, as illustrated in FIG. 5B. This enables the plural leads with different distances to be separated by the groove portions 16. Thus, the attachment part 1 improves its versatility.
Next, a description will be given of the through hole 14 and the projection portion 30. FIG. 6 is an enlarged view of the attachment part 1 when viewed from the rear surface 13. As illustrated in FIG. 6, the through hole 14 has an oblong hole shape extending horizontally. With this arrangement, the attachment part 1 can be adapted to the plural optical components with the different distances between two leads. In this way, the attachment part 1 has the versatility. Further, the through hole 14 is provided with bump portions 141 facing each other to separate two leads.
That is, by the bump portions 141, the width of the through hole 14 is partially narrow so as to separate two leads. This arrangement also prevents the shorting of the leads.
The projection portion 30 will be described. The projection portion 30 includes two projective pieces 31 elastically deformable to move into and out of contact with each other. The projective pieces 31 extend downwardly in substantially parallel with each other. A flange portion 311 is provided at an end portion of the projective piece 31. When the projection portion 30 is inserted into the attachment hole 83 of the printed substrate 80, the flange portions 311 abut an edge of the attachment hole 83 to be elastically deformed to thereby move toward each other. When the flange portions 311 pass through the attachment hole 83, the flange portions 311 are returned to the original states by their elastic restoring forces. Therefore, the flange portions 311 engage the attachment hole 83. Accordingly, the attachment part 1 is attachable to the printed substrate 80 with ease, thereby improving the workability.
Next, a description will be given of an attachment part 1 a according to the second embodiment. Additionally, the same components as the first embodiment have the same reference numerals in order to avoid a duplicated explanation. FIGS. 7A to 7C are explanatory views of the attachment part 1 a according to the second embodiment.
As illustrated in FIG. 7A, protruding pieces 151 and recess portions 153 are arranged in the vicinity of the through hole 14. The protruding piece 151 projects from an upper surface of the through hole 14 to its lower surface. The recess portion 153 is arranged at the lower surface of the through hole 14 and at a position that corresponds to the protruding piece 151. FIG. 7B is an enlarged view of the vicinity of the protruding piece 151 and the recess portion 153. Additionally, FIG. 7B illustrates the state where the leads 94 a penetrating through the through hole 14 is not yet sandwiched by the through hole 14. The protruding piece 151 has an end with a flange portion. Further, the recess portion 153 has a step shape, and its width decreases as its depth increases. When a base portion 10 a is pushed upwardly and downwardly, the through hole 14 is crushed, so that the end of the protruding piece 151 fits a narrow width portion of the recess portion 153 as illustrated in FIG. 7C. The fitting of the protruding piece 151 and the recess portion 153 is maintained by frictional resistances of the end of the protruding piece 151 and the narrow width portion of the recess portion 153. This maintains the state where the base portion 10 a is pushed. That is, the protruding piece 151 and the recess portion 153 correspond to a base lock portion. Thus, the state where the through hole 14 is crushed is maintained, whereby the state where the leads 94 a are sandwiched by the through hole 14 is maintained. Accordingly, the operator does not have to constantly push the base portion 10 a, thereby improving the workability.
Next, a description will be given of an attachment part 1 b according to the third embodiment. FIGS. 8A to 8C are explanatory views of the attachment part 1 b according to the third embodiment.
As illustrated in FIG. 8A, a lever portion 40 b is provided at the rear surface 13 of a base portion 10 b. The lever portion 40 b is provided at an upper side of the through hole 14. The lever portion 40 b has a thin plate shape. The lever portion 40 b has a thin portion 42 provided near the base portion 10 b. The thin portion 42 permits the lever portion 40 b to be readily bent. The lever portion 40 b has a function for aiding to bend the leads 94 a.
As illustrated in FIG. 8B, when the lever portion 40 b is bent from the horizontal state to the vertical state along the rear surface 13, the lever portion 40 b simultaneously pushes and bents two leads 94 a. This facilitates the work of bending the leads 94 a, and also improves the workability.
In addition, when the lever portion 40 b is bent from the horizontal state to the vertical state, the force is exerted to compress the base portion 10 b upwardly and downwardly, thereby crushing the through hole 14. Therefore, the leads 94 a are sandwiched by the through hole 14, thereby preventing the optical component 90 a from being displaced with respect to the base portion 10 b. That is, by the work of bending the lever portion 40 b, the prevention of the displacement mentioned above and the work of bending the leads 94 a are accomplished as a series of operations. Consequently, the workability is improved.
Next, a description will be given of an attachment part 1 c according to the fourth embodiment. FIGS. 9A and 9B are explanatory views of the attachment part 1 c according to the fourth embodiment. As illustrated in FIG. 9A, arm portions 48 are formed at opposite end portions of a lever portion 40 c, respectively. Further, insert holes 18 are formed to positionally correspond to the arm portions 48. The arm portion 48 has a substantially U shape when viewed from its side. The arm portion 48 and the insert hole 18 are engageable with each other.
FIG. 9B illustrates a cross section of a state where the arm portion 48 engages the insert hole 18. The arm portion 48 has: a first extending portion 482 extending in a direction substantially perpendicular to the main surface of the lever portion 40 c; and a second extending portion 484 curving in a direction substantially opposite to the extending direction of the first extending portion 482. The first and second extending portions 482 and 484 are elastic deformable to be close to each other. The insert hole 18 has a stopper 186 corresponding to a corner of a base portion 10 c. The arm portion 48 has a sliding surface 485 slidably contacting the stopper 186 when the lever portion 40 c is bent to insert the arm portion 48 into the insert hole 18. The sliding surface 485 is designed to have a given inclined angle, in order to facilitate the insertion of the arm portion 48 into the insert hole 18. The arm portion 48 has a step portion 486, which engages the stopper 186 when the arm portion 48 is deeply inserted into the insert hole 18. By engaging the stopper 186 with the step portion 486, the state where the arm portion 48 is inserted into the insert hole 18 is maintained. The state where the lever portion 40 c is bent along the rear surface 13 is locked. In other words, the arm portion 48 and the insert hole 18 correspond to a lever lock portion.
Additionally, when the lever portion 40 c is bent as mentioned above, the leads 94 a are covered with the lever portion 40 c and the base portion 10 c. This prevents the leads 94 a from being corroded. Further, this prevents another part from contacting the leads 94 a. Therefore, even when the whisker is generated in its lead or another lead, the leads can be prevented from short-circuiting each other.
Next, a description will be given of an attachment part 1 d according the fifth embodiment. FIGS. 10A to 10C are explanatory views of the attachment part 1 d according to the fifth embodiment.
As illustrated in FIG. 10A, a lever portion 40 d is provided with guide pieces 49. The guide pieces 49 protrude like an arc from a surface, which can face the rear surface 13, of the lever portion 40 d. Further, the insert holes 19 are provided in the rear surface 13, and each has an arc shape when viewed from their sides. Furthermore, two groove portions 46 are provided in the lever portion 40 d at its surface capable of facing the rear surface 13.
FIGS. 10B and 10C are cross-sectional view for illustrating a guide piece 49 and the insert hole 19. The guide piece 49 has the substantially arc shape centering on a pivot point of bending the lever portion 40 d. The shape of the insert hole 19 is complementary to that of the guide piece 49. When the lever portion 40 d is bent along the rear surface 13, the guide piece 49 is inserted into the insert hole 19, as illustrated in FIG. 10C. The insert hole 19 and the guide piece 49 are formed in such complementary shapes, whereby the movement of bending the lever portion 40 d is guided by engaging the insert hole 19 and the guide piece 49 until the lever portion 40 d is bent along the rear surface 13.
Additionally, when the lever portion 40 d is bent, the force is exerted to a base portion 10 d to crush the through hole 14. Therefore, the guide piece 49 slightly moves downwardly with respect to the rear surface 13. The locations of the guide piece 49 and the insert hole 19 are designed in light of the movement of the guide piece 49 relative to the rear surface 13. Accordingly, the guide piece 49 is smoothly inserted into the insert hole 19, thereby improving the workability.
Moreover, the plural leads are separated by the 46 with the lever portion 40 d bent along the rear surface 13. This prevents the short-circuiting the leads.
A next, a description will be given of an attachment part le according to the sixth embodiment. FIGS. 11A to 11C are explanatory views of the attachment part 1 e according to the sixth embodiment.
As illustrated in FIG. 11A, each of groove portions 16 e is made narrower from the upper side to the down side. FIG. 11B illustrates the state where the leads 94 a, which have a comparatively short distance between themselves, are accommodated in the groove portions 16 e, respectively. Since the distance between the leads 94 a is short, the leads 94 a are guided by the groove portions 16 e to increase the distance from the secured end side to the free end side.
FIG. 11C illustrates the state where the leads 94 c, which have a comparatively long distance, are accommodated in the groove portions 16 e. Since the distance between the leads 94 c are comparatively long, one of the leads 94 c is linearly guided by the groove portions 16 e. The other of the leads 94 c is guided to increase the distance between the leads 94 c.
In any pair of the leads 94 a and 94 c, the distance near their free ends are brought into constant. That is, the shapes of the groove portions 16 e guide the plural leads to make the distance thereof constant from their secured ends side from their fee ends side. Therefore, the various optical components can be attached to the printed substrate without changing the position of the hole, provided in the printed substrate, for the lead. Consequently, the versatility of the attachment part 1 e is improved.
Next, a description will be given of an attachment part if according to a seventh embodiment. FIGS. 12A and 12B are explanatory views of the attachment part if according to the seventh embodiment.
As illustrated in FIGS. 12A and 12B, holding pieces 21 f to 23 f are close to each other from a base portion 10 f side to a partway between the base portion and ends side. Additionally, the holding pieces 21 f to 23 f are away from each other from the partway to their ends side. Since the holding pieces 21 f to 23 f are away from each other from the partway to their ends side, the insertion of the optical component into the holding pieces 21 f to 23 f is facilitated. This improves the workability.
Next, a description will be given of an attachment part 1 g according to the eighth embodiment. FIGS. 13A and 13B are explanatory views of the attachment part 1 g according to the eighth embodiment.
As illustrated in FIG. 13A, the attachment part 1 g is capable of holding an optical component 90 d having three leads 94 d. Three leads 94 d extend from a chassis 92 d so as to form a regular triangle shape. A through hole 14 g is provided to correspond to each position of the leads 94 d. That is, the center portion of the through hole 14 g projects upwardly, when viewed from the rear surface 13 side. Therefore, the attachment part 1 g is capable of holding the optical component 90 d having three leads 94 d, as illustrated in FIG. 13B. Further, three groove portions 16 g are formed in the rear surface 13. This prevents the leads 94 d from shorting. Additionally, the attachment part 1 g is also capable of holding the above mentioned optical components 90 to 90 c each having two leads. This is because two leads can be inserted into the through hole 14 g.
Next, a description will be given of an attachment part 1 h according to the ninth embodiment. FIGS. 14A and 14B are explanatory views of the attachment part if according to the ninth embodiment and an attachment part 1 i according to a variation of the ninth embodiment.
As illustrated in FIG. 14A, the base portion 10 is provided with projection portions 30 and 30 h. The projection portions 30 and 30 h are substantially parallel to each other. The projection portion 30 h has a columnar shape. The printed substrate is provided with holes into which the projection portions 30 and 30 h can be fit respectively, and the projection portions 30 and 30 h are fitted into the holes, respectively, thereby preventing the rotation of the attachment part 1 h with respect to the printed substrate. Further, the base portion 10 is provided with the projection portions 30 and 30 i, as illustrated in FIG. 14B. In this case, the attachment part 1 i is also prevented from rotating with respect to the printed substrate.
Next, a description will be given of an attachment part 1 j according to the tenth embodiment. FIGS. 15A, 15B, 16A and 16B are explanatory views of the attachment part 1 j according to the tenth embodiment.
As illustrated in FIG. 15A, each of projection portions 30 j includes projective pieces 31 j 1 and 31 j 2. The projective piece 31 j 1 is longer than the projective piece 31 j 2. FIGS. 16A and 16B illustrate the attachment part 1 j attached to the printed substrates 80 and 80 a each having a different thickness. The printed substrate 80 is thicker than the printed substrate 80 a. The attachment part 1 j is secured on the printed substrate 80, which is comparatively thick, by engaging the projective piece 31 j 1 therewith. In contrast, the attachment part 1 j is fixed on the printed substrate 80 a, which is comparatively thin, by engaging the projective piece 31 j 2 therewith. In this manner, the attachment part 1 j is attachable to the printed substrate with a different thickness, and improves its versatility.
Next, a description will be given of an attachment part 1 k according to the eleventh embodiment. FIGS. 17A and 17B are explanatory views of the attachment part 1 k according to the eleventh embodiment.
As illustrated in FIGS. 17A and 17B, one of projection portions 30 includes two projective pieces 31 k 1 and two projective pieces 31 k 2. The projective piece 31 k 1 is longer than the projective piece 31 k 2. As illustrated in FIG. 17B, two projective pieces 31 k 1 are provided on the diagonal line, and two projective pieces 31 k 2 are also provided on the other diagonal line. The attachment part 1 k is fixed on the printed substrate, which is comparatively thick, by engaging the projective pieces 31 k 1 therewith, whereas the attachment part 1 k is fixed on the printed substrate, which is comparatively thin, by engaging the projective pieces 31 k 2 therewith. Further, the projective pieces 31 k 1, each having an identical length, are provided on the diagonal line, and the projective pieces 31 k 2, each having the identical length are provided on the other diagonal line, thereby securely fixing the attachment part 1 k on the printed substrate.
