Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conductive connector for electrically connecting the technical field, and particularly to a conductive connector having elasticity and an assembly of circuit components using the same.

PRIOR ART Conventionally known conductive connectors of this type are simply laminated with an elastic insulator layer and an elastic conductor layer, so the connected portion on the circuit component is connected to the conductive connector. They must be spread out along the stacking direction, which has the disadvantage of increasing the size of the circuit components.

FIG. 1 shows a conventional example of this kind, in which (a) shows a main body of a conductive connector, and this conductive connector has an elastic insulator layer (b) and an elastic conductor layer (c) layered one after another.
It is formed as an integral piece of laminated structure.

Connecting terminal groups (t) and (g) are formed on the printed circuit boards (d) and (e) as circuit components at positions facing each other, and these are connected with the conductive connector (a) in between. When the board is pressed down and fixed, each connection terminal group (f
) (g) are configured to be electrically connected.

Connection using such a conductive connector is possible because the conductive connector itself is made of an elastic material.
) (g) and the conductor layer (b), which has the advantage of minimizing failures due to poor contact. Since the interval between the terminals must be sufficiently larger than the width of the conductor layer of the conductive connector, there is an inconvenience that the connecting terminals must be spread out along the stacking direction of the conductive connector. Therefore, when using a conventional conductive connector, the length of the conductive connector of the circuit component must be increased in the stacking direction, and as the number of connection terminals increases, the conductive connector itself also becomes longer. This had the disadvantage of being subject to significant restrictions, especially when incorporated into something with limited space, such as a camera.

Purpose This invention was made in order to eliminate the above-mentioned drawbacks of the conventional products, and its purpose is to provide a conductive connector that retains the advantages of the conventional products and can be constructed compactly. The object of the present invention is to provide a circuit component assembly using the same.

Embodiment FIG. 2 shows an embodiment of the present invention, in which (1) is a conductive connector according to the present invention, and this conductor and connector are made of elastic conductor layers (2) (4) 4 elastic insulators. It has a first unit (6) and a second unit (7) in which layers (8) and (5) are laminated in sequence, and both units (6) and (7) have a flexible insulating sheet (8). They are integrated and pasted together. Elastic insulation layer (3)
(5) is made of insulating rubber, and has a grooved elastic conductor layer (2).
) (4) is made of a rubber member mixed with fine carbon powder. ← From the liquid crystal sealed between n5-0, the polarizing plate (12) provided on the upper glass plate, and the polarizing plate (not shown) provided on the lower surface of the lower glass plate (11). It has become. Lower glass plate (
A part of 11) protrudes from the upper glass plate, and a connection pattern consisting of a large number of connection terminals is printed on that part. As is clear from the figure, each of the connection terminals consists of a bulge as a connected part to ensure the connection state, and a conductor extending from the bulge, and in the case of this embodiment, each bulge The portions are arranged in parallel to form a first pattern (18a) and a second pattern (13b).

Furthermore, these patterns are arranged so that the bulges of one pattern are adjacent to the interval between the bulges of the other pattern, so when viewed as a whole, the bulges appear in a zigzag pattern in the arrangement direction. It is configured to be located. The distance between the bulges of the first pattern and the bulges of the second pattern is slightly larger than the width (thickness) of the insulating sheet (8) of the conductive connector.

(14) is a holder made of an insulating material, and its upper surface has a recess (14a) for positioning and holding the liquid crystal unit (9), and a regulating wall for regulating blind movement of the conductive connector in the longitudinal direction. (14b) (14c) are formed. (14d) is a long hole provided so that the liquid crystal can be observed. (15) is a so-called flexible substrate made of a flexible material, and its bottom surface has
A third pattern (1
6a) and a fourth pattern (16b) are printed in a similar arrangement, and conductive wire portions extending from these are connected to circuits and circuit elements not shown, respectively. (1
7) is a presser plate made of insulating material; (18) (19)
) is a set screw that fixes the holding plate and the flexible substrate (15) to the holder (14).

In the above configuration, in order to connect the liquid crystal unit and the flexible board, first fit the liquid crystal unit (9) into the holder (14), and then attach a conductive connector to the part of the lower glass plate (11) where the connection pattern is printed. (
1), overlay the flexible board (15) and holding plate (17) on this conductive connector, and insert the set screws (18) and (19) into the holder through the holes formed at both ends of the flexible board and holding plate. If you screw it on, it will work. In this state, the liquid crystal unit (9) is accurately positioned at a predetermined position on the holder by the four parts (14a) formed on the surface of the holder, and the conductive connector (1)
Also, the side end surface (10a) of the upper glass plate and the end surface (10a) of the holder
4e) and the regulating walls (14b) (14c), it is held accurately on the connection pattern. On the other hand, since the flexible board (15) is fixed in a predetermined positional relationship to the holder (14) by the setscrew, the lower surface of the conductive connector (1) has first and second patterns (18a) (13b). are in contact with each other, and the third and fourth patterns (16a) (16b
) comes into contact. Since the set screws (18) and (19) are tightened to compress the conductive connector (1) made of an elastic body, the conductive connector and each connection pattern are reliably connected with appropriate contact pressure.

FIG. 3 shows this connection state, and as is clear from the figure, the first pattern (18a) and the third pattern (16
a), and the respective bulges of the second pattern (18b) and the fourth notch turn (16b) are overlapped in a vertical positional relationship (in the direction perpendicular to the plane of the paper), and a conductive connector is placed between them. Since the elastic conductor layers (2) and (4) of (1) are positioned and pressed against these bulges, the bulges facing each other are electrically connected. Furthermore, since the elastic insulating layers (8) and (5) of the conductive connector are located between adjacent bulges (and conducting wires), there is no possibility that they will be accidentally connected. moreover,
As described above, since the eight components, including the liquid crystal unit, the conductive connector, and the flexible substrate, are positioned respectively through the holders, there is no inconvenience caused by such misalignment of the connection state.

In the same figure, the opposing bulges are shown slightly shifted from each other for convenience of explanation, but in reality, they overlap accurately due to the above positioning. However, as shown in the figure, even if these bulges are slightly shifted, this does not have any particular adverse effect on the connection state.

In the above embodiment, the connection patterns on the flexible substrate and the liquid crystal unit are arranged so that the connected portions, that is, the bulged portions at the tips thereof, are arranged in a zigzag shape, but this configuration saves space in the arrangement direction. It has the advantage of being small. That is, in those using conventional conductive connectors, the connection patterns are simply arranged in a line as shown in FIG. 4 (5), and in this case, the width of the bulge (h) is set to 0. If there are 5 fights and the distance to the next bulge is also 0.5 fl, their pitch is 1.0 s + g
becomes.

On the other hand, when the conductive connector according to the present invention as described above is used and the bulges in the connection pattern are arranged in a zigzag pattern, each bulge is arranged in a zigzag pattern as shown in FIG. The width of (18a') and (13b') is 0.5 fin, and the interval between the narrowest parts of each terminal is 0.5f.
If i and the width of the conducting wire portion are 0.2 all, the pitch is 0.85 m, which has the advantage that the length in the arrangement direction can be made smaller by 0.85 times compared to the conventional example 10-.

As described above, since the conductive connector according to the present invention allows the width of the board to be made compact, it is particularly suitable for use in small devices with limited space, such as cameras, calculators, and small radios. FIG. 5 shows an example of the incorporation into a camera. The figure shows an example in which a conductive connector is used to connect the flexible board to the liquid crystal display that displays shutter speed, aperture value, etc. in the viewfinder.
It is basically the same as the one shown in the figure, but has been slightly arranged for installation.

In the figure, (20) is a pentaprism, (21) is a focus plate, and (22) is an eyepiece lens.To cover these finder components, an upper cover (23) and a front cover (24) are attached to the camera body ( (not shown). (25) is a transparent member forming a lighting window, and a liquid crystal unit (26) is placed directly below it. The liquid crystal unit (26) has the same structure as the embodiment shown in the second figure, although the vertical relationship is reversed, and is positioned and fitted into the holder (27). As mentioned above, the flexible substrate (28) with a connection pattern printed on its upper surface is fitted into the holder (27), and the conductive connector (1) and the liquid crystal unit (26) are superimposed on it. Furthermore, a retaining member (29) is provided to prevent the conductive connector from coming off, and a holding plate (30) is provided to press it down. Since the holding plate (30) is fixed to the holder (27) so as to compress the conductive connector, sufficient contact pressure with each connection pattern is obtained, and electrical connection is reliably maintained. (81a) (31b) (8]c)
is a known reflective optical element.

In the finder configured as described above, external light entering through the transparent member (25) illuminates this liquid crystal unit, and the transmitted light passes through the reflective optical elements (81a) to (81).
c) into the pentaprism (20), so the number indicating the shutter speed or aperture value appearing on the liquid crystal unit (26) is the same as that of the eyepiece (22).
It becomes visible through the photographic cloth.

In the above embodiment, the liquid crystal unit and the 71/XP board were cited as circuit components, and the connection state thereof was shown, but the present invention is not limited to this, and can also be applied to the case where boards are connected to each other. Yes, I will give an example below just in case.

In FIG. 6, (85) is a holder, and its upper surface has a recess (85) shaped so that the first substrate (36) fits into the bottom.
85a) are formed, and positioning pins (35b) (85c) and screw holes (35d) (3
5e) is provided. As described above, a connection pattern (only a part of which is shown in the figure) in which the bulges are arranged in a zigzag pattern is printed on the upper surface of the first substrate (36). (37) is a conductive connector having the same configuration as the previously described embodiment, and (38) is a second board, on the bottom of which are printed four connection patterns corresponding to the connection patterns of the first board. has been done. (39) is a holding plate, and (40a) and (40b) are set screws. In the case of this embodiment, the parts are superimposed in the order shown, and in particular, the first and second boards 13- (86) (88) are connected to the positioning pins (85b) (88).
5c) and set screw (4, Oa) (40b)
By inserting the screw into the holding plate and the second board, and screwing the screw into the screw hole on the holder, the boards are reliably connected to each other by the conductive connector (37).

In addition, in each of the above embodiments, only the configuration in which the connection pattern has its bulges arranged in a zigzag pattern along one direction is shown, but the connection pattern is not limited to this configuration, but can be modified as follows. It is. That is, in FIG. 7,
Figure (5) shows an example of the zigzag arrangement mentioned above.
Although this arrangement can shorten the length in the arrangement direction compared to the conventional arrangement in a single row, the length cannot be shortened due to interference between adjacent connection terminals. It's something that doesn't exist. On the other hand, in the case shown in FIGS. 5(B) and 3(C), both sides of the substrates (41) and (46) are used, and the length thereof is shortened at once. This is characterized by the fact that they are arranged not in a zigzag pattern but against each other, that is, in parallel.
(48bn) is a through hole (44bn) drilled in the board.
1) to (44n) are electrically connected to the conductive wire portion printed on the back surface of the board, and are drawn out in the same direction as the conductive wire portions of other patterns. In the same figure (0), since the through-hole parts (451) to (45n) require relatively space, the through-hole parts are arranged in a zigzag pattern to make it as compact as possible. In the case shown in Fig. 7 (C), there is no space in the direction in which the connection patterns are arranged (left and right in the figure), and there is space in the direction perpendicular to this (the vertical direction in figure C). It is effective when implemented in some cases.

C. Regarding the configuration of this through hole, in the one shown in the figure, a conductive part is formed in a border shape around the hole, but this is a so-called landless type through hole in which such a border is omitted. Furthermore, it is also possible to extend the connection terminal to the edge of the board without providing a hole, and to form a conductive part connecting both the front and back surfaces of the board on the side end surface of the board. By doing so, the pitch between the connection terminals can be further reduced.

In each of the above embodiments, an example was described in which a conductive connector consisting of a first and a second conductive unit was used to connect two circuit components, such as a board and a liquid crystal unit, or a board to each other. A connector can connect not only two circuit components, but also three circuit components. FIG. 8 shows such an embodiment, where (51) and (52) are the first and second conductive units, respectively, which are the same as those described above, together with the insulating sheet (53) provided between them. The structure forms a conductive connector. This conductive connector is housed in a holder (54) and is superimposed on the first substrate (57)-1 knee placed on the plywood (56). A second board (58) and a third board (59) are mounted on the -L side of the conductive connector, respectively.
) are superimposed in such a way that they are in contact with each other separately.

A holding plate (6o) is placed on the upper surface of these second and third boards, and is fixed to the base plate (56) by appropriate means so as to compress the conductive connector.

In this embodiment, the conductive connector electrically connects the connection pattern on the first board and the connection pattern on the second board, and the connection pattern on the first board and the connection pattern on the third board, respectively. Therefore, electrical connections are made between a total of three circuit components of the first to third boards.

In addition, in the above explanation, only an example in which a conductive connector is constructed by connecting a plurality of conductive units with a rectangular cross-sectional shape is shown, but the shape of the conductive unit is not limited to this, and the cross-sectional shape is circular or ring-shaped. It is possible even if it is a thing.

Figure 9 shows a conductive unit with a ring-shaped cross section) (61) (62
) are connected via an insulating member (63) to form a connector. According to such a connector, the hollow part (61a) of the conductive unit (6
By setting the diameter of 2a) arbitrarily, the elastic force of the entire connector can be adjusted appropriately.

In each of the above-mentioned embodiments, only the conductive connector has a configuration in which the first and second conductive units are connected in parallel on the same plane and integrated, but the present invention is applicable to such a configuration. The present invention is not limited to this, and various modified embodiments are possible, such as a combination of three or more conductive units, or a three-dimensional connection of multiple conductive units in a vertical positional relationship. A modified example will be described in detail. In the explanation, for convenience, we will broadly classify units into units connected two-dimensionally and units connected three-dimensionally, but each example is shown as an individual and independent example. Needless to say, appropriate combinations can be made between the embodiments and the embodiments described above.

[Group of embodiments in which conductive units are connected in a plane] 10th
The figure shows that the conductive unit consisting of the laminated structure of the elastic conductor layer and the elastic insulator layer is the insulating sheet (65) (65) as described above.
The figure shows three conductive 18-electrical connectors (67) connected via 6), and such conductive connectors have the effect of further shortening the length of the connection pattern in the arrangement direction. That is, as shown in the same figure (B), the connection pattern printed on the board (68) is
The bulges of each connection terminal can be arranged in three rows and arranged in a zigzag pattern as a whole. In this case, the same number of connection terminals can be arranged in two rows with the bulges arranged in a zigzag pattern. The length in the arrangement direction can be further shortened compared to the conventional one. In addition, in the case of the same figure (C), when arranging the bulges of the connection pattern in three rows, two of them
The rows are arranged in a zigzag pattern, and the other row is arranged in parallel next to them and the conductor parts are through-holes (691) to (69n).
The substrate (70) is folded back on the back surface side of the substrate (70), and by adopting such a configuration, the effect that the substrate can be formed more compactly than that shown in FIG. 7B can be obtained. Regardless of which connection pattern is used, the effect that the board can be made more compact by using such a pattern is that the conductive connector is composed of three conductive units as shown in Figure (5). It is something that occurs.

FIG. 11 shows an embodiment in which the conductive connector is formed into an L-shape. (71) and (72) are first and second conductive units each having a laminated structure as described above, and these two conductive units are bonded together in an L-shape using an insulating adhesive. , forming a conductive connector (73). In addition, the insulator layer portion (72a) of one of the conductive units is located at the connecting portion between the conductive units, thereby making the insulation between the conductive units more reliable.

(74) is the first board, and a large number of connection terminals are printed on its two sides, and these are connected to the bulge (75).
a+) to (75an) are arranged to form an L shape corresponding to the conductive connector. (76) is a second board, and its lower surface has a large number of connection terminals with its bulges (77a+) to (77an) arranged in an L-shape, similar to the connection terminals on the first board. It is printed. Then, connect these boards to conductive connectors (73).
When the substrates are brought into pressure contact with the upper and lower surfaces of the substrates, an electrical connection is established between the substrates, as in the previously described embodiments.

This embodiment is particularly effective when there is no space in a predetermined direction, for example, the X direction in the figure, but there is relatively more space in a direction perpendicular to the X direction. When conventional conductive connectors are used, the connection terminals are arranged in a row, which requires a large space in the direction of arrangement, which has the disadvantage that it cannot be used when the direction coincides with the X direction. According to the embodiment, since the length in a specific direction can be shortened, the drawbacks of the conventional example can be overcome.

In this embodiment, the two conductive units are connected at right angles, but it is also possible to connect the two units at an angle smaller or larger than 90°.

FIG. 12 shows an embodiment in which the conductive connector is formed into a mouth shape. As shown in the figure, the conductive connector (80) has the shape of a combination of two L-shaped conductive connectors of the above-mentioned embodiment. 84) by adhering and integrating them with an insulating adhesive.

A conductive connector (80) having such a shape is suitable for connecting a reflective liquid crystal and a substrate, for example, and is shown in FIG.

The aforementioned connection pattern is printed on the peripheral portion of this liquid crystal unit that comes into contact with the conductive connector (80).

(89) is a holding member, which is inserted from the top surface of the liquid crystal 2

C and is located in the hollow formed by the conductive connector.

FIG. 13 shows an example in which a conductive connector is constructed by connecting conductive units with different cross-sectional shapes. In the same figure (5), the conductive connector (91) has a first conductive connector (92) and a second conductive connector (92) formed by changing the cross-sectional shape in a plane orthogonal to the stacking direction so that the thickness is different from the first conductive connector (92). The conductive unit (9B) is formed by pasting an insulating member (94) between them. The difference t in thickness between the first conductive unit (92) and the second conductive unit (9B) is
) is set to be the same or slightly larger than the thickness. It is desirable that this thickness t be the same as or slightly larger than the thickness of the second board (96) in order to obtain sufficient contact pressure with the connection terminals, but since the conductive connector itself is made of an elastic material, the second board (96) It can be implemented even if the thickness is slightly smaller than the thickness of the substrate. (95) is the first substrate, and (97) is the eighth substrate. The connection circuits printed on each board are not shown in the figure, but are arranged as shown below. That is, a connection pattern consisting of a large number of connection terminals is printed on the top surface of the first board (95), and the bulges of some of the connection terminals extend directly below the second board (96) so as to overlap with it. The bulges of the other connection terminals are exposed at positions not covered by the second substrate (96). In addition, the second board (96) has a connection pattern printed on both the front and back sides, and the bulges of the connection terminals arranged on the back side of the first board extend directly below the second board. (95) It is printed at a position corresponding to the bulge on the top, and the connection terminal printed on the surface is placed in a position where the bulge faces the first conductive connector (92). has been done. Further, in the connection pattern arranged on the lower surface of the third substrate (97), the tip bulges of each connection terminal are arranged in two rows in a zigzag shape as described above.
One row is the first conductive unit of the conductive connector) (92
), and the other row is arranged in such a position that it can come into contact with the second conductive unit (98), respectively.

Figure (B) shows the state of connection between this conductive connector and each board. In the assembled state, each of the above-mentioned members is superimposed on the base plate (98), and the holding plate (
99), it is compressed from above.

The holding plate (99) is fixed to the plywood (98) while positioning each member by appropriate means as described above.

In this state, the connection terminals on the first and third substrates (95) and (97) are connected to each other by the second conductive unit (93) of the conductive connector, as in the previously described embodiments.
In addition, the connection terminals on the second and third substrates (sieves) (97) are connected by the first conductive unit (92),
According to this embodiment, the electrical connection between the first and second substrates is also achieved by direct contact between the connection terminals on the thin tube 1 substrate (95) and the connection terminals on the back surface of the second substrate (96). Ru. In this case, since the holding plate (99) presses the elastic conductive connector, the 25-2 board (96) is sufficiently pressed against the first board (95) by receiving the biasing force from the conductive connector. . Therefore, the first
Although the substrate and the second substrate are connected by surface contact,
There is almost no risk of poor contact due to the elastic force of the conductive connector.

[Example group in which conductive units are three-dimensionally connected] 14th
The figure shows an embodiment in which the conductive connector is three-dimensionally configured in a U-shape.

In the figure, (101) is the first conductive unit,
The elastic conductor layers (101aυ to (101an)) and the elastic insulator layers (101bυ to (101bn)) are sequentially laminated and integrated, and (102) is a second conductive unit having the same configuration. These first and second conductive units are arranged at 1° above and below so as to overlap each other.
They are arranged in a positional relationship and are adhered and integrated with an insulating adhesive with the elastic insulating members (1 (G) in between) to form a conductive connector (104) having a U-shaped cross section. The body layers (101b+) to (101bn) are made of insulating rubber, and the elastic conductor layer (101as
) to (101an) are made of rubber members mixed with a conductive material such as fine carbon powder.

(105) is the first substrate, (106) is the second substrate, (10
7) is a third board, and its mutually opposing surfaces have connection patterns (108) (108) consisting of a large number of connection terminals.
09) (IIIOXIII) is printed. Each connection terminal has a bulge formed at its tip to ensure a secure connection, and a conductor part drawn out from the bulge and connected to other terminals or circuit elements. It has become. The connection terminal (109a) printed on the second board (106) has a through hole (
The structure is slightly different from other connection terminals in that it is electrically connected in advance to the connection terminal on the back surface side via 106a).

Next, we will explain the case where the conductive connector having the above configuration is used to connect between boards. First, the gap (104a) between each conductive unit of the conductive connector (104)
Insert the second board (106) into the board, and then insert the first board (106) into the
5) and the third board (107) are pressed against the conductive connector from above and below, respectively.

Then, in this superimposed state, the presser plates (not shown) are inserted from below to compress the conductive connectors and fix the presser plates to each other.

In this case, it is desirable to provide a suitable positioning means to specify the positional relationship of each board with respect to the conductive connector. As a positioning means, for example, a plurality of round holes are provided in the conductive connector and each board. It is possible to provide a configuration in which a round hole is provided and a set screw for fixing the presser plates to each other is passed through the round hole.

When combined as described above, since the conductive connector itself is formed of an elastic body, the conductive connector can come into contact with each connection terminal with sufficient contact pressure. The first conductive unit (101) of the conductive connector electrically connects the connection pattern (109) of the second board-L and the connection pattern (111) of the third board-L,
The connection pattern (10g) on the first substrate and the connection pattern (110) on the back surface of the second substrate are electrically connected by the second conductive unit (102). In addition, since the connection terminal (109a) on the second board is connected in advance to the connection terminal on the back side via the through hole, the connection terminal (109a) on the second board is connected to the first and corresponding connection terminals via the conductive connector. The connection terminals on the three substrates are electrically connected to each other.

In this embodiment, since the conductive connector (104) is configured by three-dimensionally connecting two conductive units in a vertical positional relationship, the second board (106) has a connection pattern on both sides. Compared to the conventional configuration in which connection terminals are simply arranged on one surface of the board, the length of the board in the direction in which the connection terminals are arranged can be significantly reduced.

Further, the conductive connector in the above embodiment is formed in a substantially U-shape, and a board can be held in the gap (104a), and functions as a so-called socket. Conventional sockets have a structure in which a large number of plate spring contact pieces are arranged inside a sheath-shaped package made of synthetic resin, for example, and these plate spring contact pieces elastically press a board inserted through the opening of the package. It was designed to be held in place. However, in conventional sockets like this, the plate spring contact piece has to be made into a large member because it is necessary to give the plate spring contact piece sufficient strength to hold the board, and therefore the arrangement pitch of the contact pieces is also limited. This has the drawback of increasing the overall shape of the socket. In contrast, in the conductive connector according to the second embodiment, the entire connector is made of an elastic material, so the gap (104a) is made smaller than the thickness of the board (106) to be inserted. Just by placing it in place, the board can be reliably held by the elastic force of the entire connector. Furthermore, since the entire connector has elastic force, there is no need to make the conductor particularly large in order to obtain elastic force, and the width of the conductor layer portion and the pitch between them can be reduced. Therefore, there is an effect that the overall shape can be made smaller.

In the above description, an insulating member (10B) is interposed between the first conductive unit and the second conductive unit to form a U-shape as a whole.
0B) is not necessarily necessary; for example, one conductive unit may be formed into a shape in which this insulating member is integrated, that is, a member with an angular cross section, and then the other conductive unit may be It is also possible to form a U-shaped conductive connector by connecting the two through an insulating adhesive. In this case, the insulation between the first and second conductive units will be provided by adhesive.

If the substrate to be held is still extremely thin, the insulating member (10B) may be omitted and both conductive units may be directly connected using an insulating adhesive; in this case, To hold the board, insert the board by pushing out the non-adhesive part.

Further, in the above embodiment, the conductive connector is formed to have a U-shaped cross section, but it is also possible to form the conductive connector to have a seven-shaped cross section, as shown in FIG.
In this case, by bonding the curved first conductive unit (11, 2) and the second conductive unit (11B) via the insulating member (114), a conductive connector (115) having an L-shaped cross section is formed in a layered manner. It is something that will be done. According to a connector with such a shape, since the conductive unit is curved, the elastic force can be adjusted by changing the curvature, and it is possible to adjust the elastic force within a possible range by selecting the material of the connector. This provides the effect of making it possible to adjust the elastic force.

FIG. 16 shows a modified embodiment of the above-mentioned U-shaped conductive connector. In the previously described one, the first conductive unit and the second conductive unit are completely insulated from each other. This embodiment differs from those described above in that both of these conductive units are provided with a portion to which they are electrically connected.

That is, the conductive connector (121) has a laminated structure of an elastic conductor layer and an elastic insulator layer, as described above.
The conductive connector has a first conductive unit part (121a) and a second

) are formed. Therefore, the first substrate (12B),
When the second board (124>) and the third board (125) are each combined with the conductive connector (121) as described above, several connections can be made as follows.

That is, in the portion where the insulating members (122a) to (122c) are provided, as described above, the connection terminal on the second board (124) and the third board (125) are connected by the first conductive unit part (121a). The connection terminal on the back side is also connected to the second
The first substrate (12B) is connected by the conductive unit part (121b).
) and the connection terminals on the back surface of the second substrate (124) are electrically connected, respectively. In addition, parts (121c) to (121c) where both conductive unit parts are electrically connected are also provided.
In 1e), depending on the combination with the arrangement of the connection terminals,
Connection terminals on all boards or terminals on any two boards can be electrically connected to each other. For example, if connection terminals are arranged at opposing positions on the first board (12B) and third board (125), and no connection terminals are provided at the corresponding positions on the second board (124), the first and the terminals on the third board are electrically connected =33=. If the connection relationship between these boards is set to 1, it will be as shown in the following table.

On the other hand, the above embodiment described a configuration in which an insulating member is partially interposed between two conductive unit parts, but such a configuration in which an insulating member is provided is implemented in a conductive connector consisting of a single conductive unit. It is also possible. In this case, since the insulating member is interposed in such a way that the elastic conductor layer is divided into two in a direction perpendicular to the lamination direction, there are parts that require continuity when connecting the two boards and parts that do not. This is particularly effective in cases where

Furthermore, the structure 34- in which an insulating member is interposed in this way has three conductive unit parts (12
6a) (126b) (126c) may be integrated into a conductive connector (126) formed in an E-shaped cross section. In this case, how many insulating members are further provided in the direction perpendicular to the lamination direction. (For example, insulating material (127) (1
There is an effect that the connection relationships between the boards can be further diversified depending on whether two layers are provided across one conductor layer (126d) as in 28).

Fig. 18 shows a conductive connector (181) which is a further development of the above-mentioned U-shaped conductive connector, and has a shape in which the U-shaped connectors are integrated back to back, that is, a cross section with a straight-shape shape. I'll tell you. (1B2a) and (l112b) are insulating members inserted after cutting out a part of a cross-shaped conductive connector, and elastic conductor layers adjacent to this insulating member are insulated from each other. . In other parts where the insulating members (182a) (182b) are not provided, the first to fourth conductive unit parts (181a)
) (181b), (181c), and (laid) are each formed integrally, so the respective conductive unit parts are connected to each other in a conductive state.

In the illustrated example, an insulating member (1B2a) is interposed to electrically isolate each conductive unit, but the thickness t of this insulating member is made small, and the first conductive unit part (181a) and the fourth By leaving a portion connecting the conductive unit parts (laid), the first and fourth conductive unit parts are electrically connected to each other, and only the relationship with the remaining conductive units is insulated. You can also do it.

This cross-shaped conductive connector (181
), as shown in the figure, the first to fourth substrates (18B) to
(186) enables extremely diverse electrical connections between at least four boards, but since it can be formed thinner than the previously described E-shaped connector, it does not require much space, especially in the height direction. Suitable for integration into restricted equipment.

Fig. 19 shows an example in which a plurality of conductive units are connected in a stepwise manner to form - conductive connectors, and in the same figure, (141) and (142) are formed from the laminated structure described above. These units are directly connected with an insulating adhesive while being shifted in a predetermined direction, or with an elastic insulating sheet (1) as shown in the figure.
4B). (144) is a first board, (145) is a second board, and a first connection pattern (146) and a second connection pattern (147) are printed on the upper surface of each, and each bulge is printed on the top surface of each. parts (146a+) to (146an) and (147
a+) - (147an) is the first conductive unit (141
) and the second conductive unit) (142). (148) is the third substrate, (149)
) is the fourth board, and a connection pattern is printed on the bottom surface of each board, and their bulges (148a1)
~(148an) and (149a□) ~(149an
) are arranged at positions facing the bulges on the first and second substrates. Further, connection patterns (none of which are shown) are printed so as to face each other on the surfaces of the first and second substrates that are in contact with each other, and on the surfaces of the eighth and fourth substrates that are in contact with each other. As shown in the figure, when the two substrates are stacked on top of each other, the opposing connection patterns 87- are configured to be in contact with each other. The first and fourth substrates (144) and (149) are respectively so-called flexible substrates made of flexible materials, and the second and third substrates (145) and (148) are rigid substrates.

In the above configuration, when each component is stacked in the order shown in the figure and fixed by being sandwiched between the upper and lower parts by pressing members (not shown), the first conductive unit (141) connects the first board (144) and the third board (141). In the previous embodiments, the second substrate (145) and the fourth substrate (149) are electrically connected by the second conductive unit (142). Same as in case. Furthermore, since the first conductive unit (141) presses the third board (148) onto the fourth board (149) by its elastic force, the connection patterns printed on the opposing surfaces of these two boards are sufficiently connected to each other. directly connected with sufficient contact pressure. Similarly, since the second board (145) is pressed against the first board (144) by the elastic force of the second conductive unit (142), the connection patterns printed on their opposing surfaces are securely connected to each other. be done.

38- According to this embodiment, the conductive connector serves as an intermediate member that connects the terminals, and at the same time functions as a suppressing member that presses the stacked boards together so that they are in opposing contact. This has the effect of enabling a variety of connections.

FIG. 20 shows an embodiment in which a conductive connector is used as a socket, which is a further development of the embodiment shown in FIG. This makes it easier to handle.

Figure (5) shows the configuration and positional relationship between the conductive connector (151) and each board.The structure of each component is essentially the same as that of the embodiment shown in Figure 14, so the explanation will not be repeated. To omit this and explain only the points that are different from those already described, the conductive connector (151) is connected to the tip end face (152a) (15B) of each conductive unit (152) (15B).
58a) is chamfered and has a plurality of through holes (154) for positioning.

In the case of this embodiment, the through hole is a conductive connector (151)
One through hole (154) is provided at each end in the longitudinal direction (laminated direction), and for convenience, only one through hole (154) is provided in the figure.
only is shown. The connection pattern is printed on the first substrate (155) and the third substrate (157) as described above, and especially in the case of this embodiment, the surface of each substrate is provided with a protective layer made of an insulating material to prevent short circuits. The structure is such that only the bulging portions of each connection pattern are exposed through window portions (158) and (159) formed as non-coated portions. These boards also have through holes (160) for positioning at both ends in the arrangement direction of the connection patterns.
161) (only one of which is shown in the figure), and these through holes are provided at positions corresponding to the through holes of the conductive connector.

On the other hand, what is shown in the same figure (B) is the component of the socket □
It is a pan cage (161) made of an insulating material as a product, and has a sheath-like shape as a whole, and has an opening (168a).
and an insertion port (168b) having a smaller opening area than the insertion port (168b). (168c) and (168d) are through-holes provided to penetrate the entire package, and these through-holes are formed at positions corresponding to the through-holes drilled in the board and the conductive connector, and are insulated through them. The structure is such that pins (164) and (165) can be inserted therethrough. (168e) and (163f) are mounting holes used when this pancage body is assembled into a device (not shown).

In the above configuration, first, the conductive connector (151) is sandwiched between the first board (155) and the eighth board (157), and these are inserted into the package body (
16B), and then each through hole (1
61) (154) (160) (168c) and insert the insulating pins (164) (165).
All of these members are fixed in a mutually positioned state, that is, in a state in which the connection patterns on both substrates face each other via the elastic conductor layer of the conductive connector, so that they form a single unit as a whole. If the tips of the insulating pins are crushed by, for example, thermal caulking, these members will be securely held without being separated inadvertently from now on (see Figure (C)). 41- Chamfered portion (152a) formed on the conductive connector (
151a) is a consideration to facilitate the insertion operation into this package.

To make a connection between the boards, insert the second board (156) into the unitized structure as described above through the insertion opening (168b) of the package, and position it in the gap (151a) of the conductive connector. Then, electrical connections are made between the respective substrates in the same manner as in the embodiment shown in FIG. 14 described above.

In this case, the second board (156) is held in place by the elasticity of the conductive connector itself,
Moreover, the elasticity of this conductive connector remains constant over time compared to conventional sockets that utilize the elasticity of the leaf spring contact piece, so it is possible to repeatedly insert and remove the board as needed. Even if this is done, it is always held securely in the inserted position and there is no risk of contacting the contact means.

FIG. 21 shows a further modified example of the above-mentioned socket, which is different from the above-mentioned embodiment in particular in that it electrically connects only two boards and in the specific configuration of the means for positioning between each component. They have different configurations.

In the same figure (A), a conductive connector (171) is a single conductive connector (1, 72) and an elastic body (178) made of insulating rubber, which are connected and integrated via an insulating adhesive (174). The cross section as a whole has a U-shaped cross section, and has a gap portion (171a) having a width slightly smaller than the thickness of the first substrate (175). Positioning holes (176) are provided near both ends in the longitudinal direction of this conductive connector, and the side end surfaces of this connector are chamfered as in the above embodiment. The second substrate (177) is provided with a protective layer made of insulating paint on the connection pattern,
Each bulge is formed so that only it is exposed through the window (178) of the coated part, and positioning holes (
179) is formed. On the other hand, on the inner upper wall of the package body (180) shown in FIG.
0a) (180b) are integrally molded, and they are arranged so as to correspond to the positioning holes (179) (1, 76). In addition, a locking protrusion (1
80d) is integrally formed with the locking protrusion (180d).
d) is formed with a tapered surface (180e) (see (C) in the same figure) so as to guide the conductive connector into the inside of the package.

In the second configuration below, in order to assemble the second board and the conductive connector into a unit as a socket, with the second board (177) stacked on the conductive connector (171), open the opening (180c). Insert into the package and attach the package side hanging pins (180a) (180b)
holes (179) (176) of the board and conductive connector
All you have to do is fit it into Kumobei. This state is shown in the same figure (C), but in this unitized state, the positional relationship between the second board and the conductive connector (172) is specified by the hanging pin. , the bulging portion of the connection pattern and the conductor layer portion of the conductive unit are in opposing contact with each other. Further, since the locking protrusion (180d) is located at the rear lower part of the conductive unit, there is no risk that the conductive connector will be pulled out or its posture will be distorted.

Then, in order to make connections between the boards, the first board (175
) from the insertion opening (180f) and positioning it in the gap (171a) of the conductive unit. In this case, the inserted board is elastically held by the conductive connector, and is inserted through the conductive unit (172). The electrical connection to the second substrate (177) in the package is exactly the same as in the above embodiment.

As detailed above, conductive connectors of various shapes can be constructed by connecting a plurality of conductor units two-dimensionally or three-dimensionally, but further variations of conductive connectors can be made by adding the modifications described below. can be increased.

FIG. 22 shows erosion of the peripheral side of the conductive connector (181). If unnecessary parts that do not contribute to electrical connection are covered with insulating material in this way, it is possible to prevent accidental short circuits when installed in equipment, and still support the conductive connector. There are advantages such as the ability to form the holder of the stopper with a material of the @ genus. In this embodiment, an insulating sheet is attached as the insulating coating layer, but the same effect can be obtained by simply applying an insulating paint.

Furthermore, in the embodiments described so far, each conductive unit constituting the conductive connector has the same pitch between the conductor portions, and the phases of adjacent conductive unit rows are the same. However, it is also possible to change these depending on the interval of the connection pattern on the connected side.

That is, FIG. 23(5) shows the conductor layer portion (188a□
) to (188an) arranged at a predetermined pitch, and a second conductive unit (184) having conductor parts (184a+) to (184an) arranged at a larger pitch. (186) and (187) are connected to form a conductive connector (185). This is a conductive connector (188), but in this case, the conductive units adjacent to each other are out of phase, that is, the conductive parts of each conductive unit are not aligned horizontally but in the stacking direction. An example is shown in which they are connected in a deviated state along the line.

In the modified examples of the conductive connector described in FIGS. 22 and 23, the conductive units are connected in a two-dimensional manner, but these modifications are not limited to this. Needless to say, the present invention can also be implemented in connected devices.

Effects According to the present invention, a plurality of conductive units each having a laminated structure of an elastic insulator layer and an elastic conductor layer are connected together via an insulator to form a conductive connector, so that there is no problem on circuit components. The connected parts of the connection terminal group can be arranged not only in a single row, but also in multiple rows corresponding to the number of conductive units, such as in a zigzag pattern or on both the front and back sides of circuit components. A special effect can be obtained by making the length of the circuit components compact in the direction in which the terminals are arranged.
