Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a board-to-board connector for directly electrically connecting two printed circuit boards, and in particular, to a mechanical device of a video device. And a board-to-board connector suitable for.

B. Prior Art The mechanical and mechanical parts used in a video device such as a typical video camera or video player at present will be described below with reference to FIG. The read / write cylinder head 43 for video signals, which constitutes the main part of the mechanical disk portion, includes a rotating cylinder, a stationary cylinder, and a drive motor for the cylinder. As shown in Fig. 3, the rotating cylinder has a certain inclination angle (usually 23 °) with respect to the magnetic tape that moves in the horizontal direction.
The rotation axis of the motor that rotates the rotary cylinder is also 23
Only tilted by °. The circuit board connected to the electrical elements directly associated with the cylinder head 43, such as the drive motor of the rotary cylinder or the electronic elements that directly control the read / write converter, may be mounted on the stationary cylinder or on the base of the motor. Since it has to be mounted directly, the above-mentioned circuit board for controlling the cylinder head 43 (referred to as a tilted board) also has to be tilted by about 23 ° with respect to the horizontal direction. Since the tilt angle of the cylinder must be strictly maintained, the cylinder head 43 is fixed at a predetermined tilt angle on a solid base 49 such as an aluminum die casting, and the mechanical deck portion is formed. .

The base 49 of the mechanical deck is horizontally assembled via the supporting members 44 and 45 with respect to a separate portion having a horizontally positioned main printed circuit board 41 (referred to as a horizontal board). It forms a deck assembly. As a result, in the mechanical / deck assembly, the printed circuit board 42 (tilted board) is attached to the main printed circuit board 41, that is, the horizontal board at an angle.

The electrical connection between these two printed circuit boards, that is, the horizontal board and the tilted board, is performed by, for example, a flat flexible board.
Cable (FFC) or flat print cable (F
A pair of connectors 46, 46 'via an electric wire 48 such as PC)
And a pair of other connectors 47, 47 ', a so-called wire-to-board connector is conventionally used.

Unlike the above-described wire-to-board connector connection, a so-called board-to-board connector that directly connects two printed circuit boards to each other without interposing an electric wire is a printed circuit board. It is known that various types of connectors are connected to each other in the vertical direction, or those that are connected to each other in the horizontal direction, and the connectors used for these connectors are all those that perform electrical connection with a piercing action. Is.

On the other hand, by fixing a connector having a hinge function to each edge portion of two printed circuit boards, the angle formed by the two boards is selected at an arbitrary angle for electrical connection, that is, a so-called hinge type. Board-to-board connectors are also known.

C. Problems to be solved by the invention When manufacturing the mechanical / decks assembly described above, the mechanical / decks part having the inclined board and the part having the horizontal board are assembled, and at the same time, the electrical properties of both circuit boards are assembled. If the automatic connection can be completed, the labor of the manual assembly can be saved, and the assembly can be easily automated. However,
Obviously, such a manufacturing method cannot be achieved using conventional wire-to-board connectors. Further, the price of the entire connector to which the connection conductor such as FFC or FPC is connected is not cheap because there is a limit to simplifying the assembly process more than before.

Further, the hinge-type connector described above is not suitable for automatic assembly of the connector because it includes the step of assembling the hinge portion of the connector. Also, hinge type connectors are not cheap,
The possibility of simplifying the assembly work of the mechanical / decks assembly itself by using the hinge type connector can hardly be expected.

Therefore, the object of the present invention is to provide one circuit board (horizontal board).
When assembling the part including the other circuit board (tilted board) with respect to the part including, the electrical connection of both circuit boards is completed at the same time as the mechanical part is assembled, and the labor saving of the assembly is possible. To provide board-to-board connectors.

D. Means for Solving the Problems The present invention provides a pair of separate and independent connectors, that is, a plug-side connector in which a plurality of connectors are juxtaposed, and a plurality of connectors respectively corresponding to the above connectors. And a connector on the receptacle side in which the connectors of (1) are arranged side by side. The connector for connecting a tilted board to a horizontal board according to the present invention comprises a plurality of connectors for connecting one connector fixed to the horizontal board to the other connector fixed to the tilted board. The electrical connection of the contact portion is maintained by the elastic force generated by superposing the corresponding contact portions of the other connector on the contact portion of the connector.

E. Embodiment An embodiment of the present invention will be described below by taking a pair of connectors used in the mechanical / deck assembly shown in FIG. 4 as an example. As can be understood from the cross-sectional view shown in FIG. 3, the mechanical deck assembly is composed of a cylinder head portion with a tilted substrate mounted and a body portion with a horizontal substrate mounted. The electrical connection is made with a connector on the inclined substrate side, that is, a connector on the plug side, and a connector on the horizontal substrate side, that is, a connector on the receptacle side. FIG. 1 shows a plug-side connector 10 according to the present invention.
Figure 2 shows a perspective view of the connector 20 on the receptacle side.

As can be seen from FIG. 1, the connector 10 on the plug side is a housing 11 made of integrally molded plastic material.
A plurality of plug-shaped connectors 12 are fixed in parallel to each other, and the contact portions 32 of the connectors are juxtaposed in two rows in the illustrated embodiment. As shown in FIG. 3, one end of the plug-type connector 12 is bent to form a contact part 32 for making an electrical connection with the contact part 35 of the mating receptacle-type connector 22. ing. Then, as shown in FIG. 3, the connector 12 is preferably juxtaposed and fixed to the housing 11 so that all the contact surfaces of the contact portion 32 are arranged on substantially the same plane. . The other end of the connector 12 is a solder for soldering to the through hole of the mounting board 33 (tilted board) for the cylinder head motor.
It comprises the tail 34.

As shown in FIG. 2, the receptacle-side connector 20 is constructed by assembling a plurality of receptacle-side connectors 22 facing each other in parallel in a housing 21 made of a plastic material. In the example of the contact part of the connection 22
35 are juxtaposed in two rows. As can be understood from FIG. 3, the contact portion 35 is provided at the end of the receptacle-side connector 22 with respect to the contact portion 32 of the mating plug-side connector 12 so that elastic force is generated by bending the connector 22. Has been formed. Third
As shown in the figure, the contact portions 32 of the connector 12 of the connector 10 on the plug side are at positions corresponding to the contact portions 35 of the connector 22 of the connector 20 on the receptacle side, respectively, and the main circuit board It is arranged so as to be parallel to the surface of 36 (that is, the horizontal substrate). Therefore, as can be understood by referring to FIG. 1 to FIG. 3, the connector on the receptacle side
When the connector 10 on the plug side is combined with the connector 20 on the plug side to form a connector for connecting the inclined board to the horizontal board, all rows of the contact portions 35 of the connectors 22 included in the connector 20 on the receptacle side and the connector on the plug side are included. All the corresponding rows of contact portions 32 of the connector 12 included in 10 are superposed almost at the same time, and the contact portions 35 of the connector 22 are all bent to generate elastic repulsion. The other end of the connector 22 is a solder for soldering to the through hole of the main circuit board 36.
It constitutes the tail 37.

Since the contact portion 32 of the connector of the connector 10 of FIG. 1 and the contact portion 35 of the connector of the connector 20 of FIG.
The array of plug-type connectors 12 of FIG.
Of the receptacle type connector 22 of FIG. 3, that is, it must have a corresponding relationship with the pitch, and as shown in FIG. 3, the contact portion of at least one of the connectors is the other contact. It is important to have a shape that gives elasticity to the contacts of the. However, the specific shape of the connector shown is merely an example, and the shape of the contact part may be changed to another shape, provided that elastic repulsion is generated at the contact part of at least one connector. Of course, it can be changed to
Needless to say, a connector of various other structures can be used to implement the present invention, for example, by changing the type to a type that is soldered to an SMT (Surface Mount Technology) pad.

Referring to FIGS. 1 and 2, the plug-side housing
It can be seen that a pair of protrusions 13 and 13 'are provided at both ends of the housing 11 and a pair of recesses 23 and 23' are provided at both ends of the housing 21 on the receptacle side. These recesses and protrusions are shaped so that they can be mated so that they can be used as an alignment means to align the connectors 10 and 20 and maintain the mated condition. After the pair of convex portions 13 and 13 'and the pair of concave portions 23 and 23' are fitted, screw holes 14, 14 'and 24, 24' for integrally fixing the housings 11 and 21 are provided. There is. These recesses and protrusions can also be used as positioning marks when assembling the mechanically defective portion and the main circuit board portion.

The other parts of the connectors 10 and 20 shown in FIGS. 1 and 2 are well-known structures that can be easily understood by those skilled in the art with reference to the drawings, and thus detailed description thereof will be omitted. However, as shown in FIG. 3, when the mechanical / decks assembly is assembled, the contact surface of the contact portion 35 of the connector 22 of the connector on the horizontal board side and the connector 12 of the connector 12 on the inclined board side. It should be noted that it is preferable that the contact surface of the contact portion 32 is placed on substantially the same horizontal plane.

The assembling work of the mechanical deck assembly will be easily understood from the above description. That is, so that the convex portions 13 and 13 'and the concave portions 23 and 23' provided on the housings 11 and 21 are fitted to each other, the mechanical and mechanical parts are placed above the horizontally placed main circuit board. The contact surface 32 of the plug-side connector 12 is elastically contacted with the contact surface 35 of the receptacle-side connector 22 by simply superposing the plug-side connector 12 downward, and a reliable electrical connection is made. In this case, it is not necessary to strictly lower the mechanical deck portion to be superposed from the upper side, so that the manual assembly is easy. After this work, the connectors are integrally fixed by screws (not shown) inserted through the openings 14, 14 'and 24, 24' provided in the connectors. If a supporting member such as 39, 39 'is used, the above-mentioned screw can be omitted.

Since the mechanical and mechanical parts are equipped with heavy elements such as cylinder heads and motors, this multi-pole connector was completely connected before fixing them with screws as described above. You can test whether or not. If any inconvenience is found by this test, the two printed circuit boards are before being fixed by screws, so that the circuit boards can be separated and the inconvenience can be easily corrected. In addition, if the result of this test is that problems such as poor contact or shorts are found, one of the circuit boards can be moved slightly back and forth or left and right to eliminate these problems. As possible, the convex portions 13 and 13 'and the concave portion 2
It is desirable that 3,23 'have a slight play when they are fitted together.

Those skilled in the art can very easily make various changes and modifications to the above-described embodiments, and the board-to-board connector that has been subjected to these modifications and repairs is naturally a technical product of the present invention. It is self-evident that it belongs to the range. For example, although the inclined board side on which the cylinder head is mounted is the plug side and the main circuit board side is the receptacle side, this is for convenience of description, and the former is a receptacle type connector connector, Changing the latter to a plug-type connector is an obvious category, and the case where a connector without elastic force was used as the connector on the plug side was explained, but both connectors have receptacle-side connectors. Deformation using a connector having an elastic force such as, or changing or omitting the fixing means of the connector including the recesses, protrusions, screws, etc. provided in the housing to another type is all obvious. Changes and corrections. Also,
The terms that can be determined relative to each other, such as the horizontal substrate and the inclined substrate, are used to avoid redundant description, and thus the technical scope of the present invention is not limited by these terms.

F. Effects of the Invention As described above, the connector of the present invention has a smaller number of parts and a simpler structure than the conventional connector, and therefore can be manufactured at low cost. The connector of the present invention is
Since the mechanical deck part with the inclined substrate can be assembled simply by superposing it on the horizontal substrate from above, not only the assembly of the mechanical deck assembly by hand is extremely simple but also the assembly by the automatic machine. It can be easily transferred to the method, and thus the cost of the video equipment can be reduced. Further, since the contact portion has elasticity, it is possible to widen the error range of the tilt angle when attaching the horizontal substrate and the tilted substrate. In the case of manual assembly work, even if the connector assembly cannot be seen due to other electronic components mounted on the board, it does not have the function of piercing the connector. The connector can be easily connected and the mechanical / decks assembly can be easily disassembled.
Inspection can be done easily.
