Pressure contact

The present invention relates to a pressure contact.

As a means for realizing electrical connection between a plurality of substrates built in an electronic device, a connection structure using a pressure contact has been conventionally provided. In this connection structure, an electrical contact is achieved by mounting a pressure contact having an elastically deformable contact portion on one substrate and pressing the conductive portion of the other substrate so as to face the contact portion. .

The following Patent Document 1 discloses a pressure contact connector including an upper flat plate portion, a lower flat plate portion, a first spring portion, and a second spring portion. In this pressure contact connector, the first spring portion connects one end of the upper flat plate portion and one end of the lower flat plate portion, and the second spring portion includes an auxiliary plate located below the upper flat plate portion and the lower flat plate portion. Connect the other end. The first spring portion and the second spring portion are wound in the same direction and are disposed at positions that do not interfere with each other when the first spring portion and the second spring portion expand and contract. In this configuration, the upper flat plate portion comes into contact with the auxiliary plate when moving slightly downward, and moves downward together with the auxiliary plate when moving further downward. Therefore, with the downward movement of the upper flat plate portion, both the first spring portion connected to the upper flat plate portion and the second spring portion connected to the auxiliary plate are compressed to generate a large pressure.

However, the usage (posture) of the pressure contact 1 is not limited to the above. For example, the pressure contact 1 may be used in such a manner that the horizontal plate portion 2 faces the vertical direction, the vertical plate portion 3 faces the horizontal direction, and the contact portion 6 faces the side.

The horizontal plate part 2 is provided with a plate surface parallel to a horizontal plane (xy plane), and has a lower surface 2a (first surface) and an upper surface 2b (second surface). As shown in FIG. 3, the horizontal plate portion 2 has an opening 2h at the center when viewed from the normal direction of the upper surface 2b, and is composed of two horizontal plate portions facing each other with the opening 2h therebetween. Yes. When these two horizontal plate portions are described separately, they may be referred to as a first horizontal plate portion 21 and a second horizontal plate portion 22 as appropriate. The first horizontal plate portion 21 and the second horizontal plate portion 22 have a rotationally symmetric shape with a virtual axis C, which will be described later, as the center, and each is elongated with the x-axis direction as the longitudinal direction and the y-axis direction as the short direction. It is formed into a shape.

The first vertical plate portion 31 extends over one end of the first horizontal plate portion 21 and one end of the second horizontal plate portion 22 such that the longitudinal direction is in the y-axis direction. Similarly, the second vertical plate portion 32 extends across the other end of the first horizontal plate portion 21 and the other end of the second horizontal plate portion 22 such that the longitudinal direction is in the y-axis direction. Thus, the first horizontal plate portion 21, the first vertical plate portion 31, the second horizontal plate portion 22, and the second vertical plate portion 32 provided continuously around the opening 2h are not easily deformed. A fixed part is formed.

On the lower surface side of one end of the first vertical plate portion 31, a bent portion 311 that is bent from the first vertical plate portion 31 to the lower surface side at a substantially right angle is provided.

The contacts 1 are located at both ends on the same diagonal line. The bent portion 311 and the bent portion 321 are attached by soldering to a circuit pattern of a circuit board (not shown).

As shown in FIGS. 4 and 5, the first spring portion 4 is provided such that the expansion / contraction direction F intersects the lower surface 2a and the upper surface 2b of the horizontal plate portion 2. The first spring portion 4 is configured by a plate wound around a virtual axis C parallel to the expansion / contraction direction F. Since the 1st spring part 4 is comprised by the plate body, as shown in FIG. 5, the shape of the cross section perpendicular | vertical to the winding direction of the 1st spring part 4 is a rectangle. The plate is spirally wound so that the longitudinal direction of the rectangle having the above-described cross-sectional shape is parallel to the virtual axis C. Since the 1st spring part 4 is comprised by the plate body wound helically, the spring span can be taken long and improvement of spring characteristics, such as being hard to sag, can be aimed at. Moreover, since the dimension of the expansion / contraction direction F of the 1st spring part 4 can be taken large, when the 1st spring part 4 bends, a big spring load can be applied to the contact part 6. FIG.

The lower end portion 4b (first end portion) of the first spring portion 4 extends horizontally from the side end portion (end portion in the y direction) opposite to the side where the bent portion 311 of the first vertical plate portion 31 is provided. The first vertical plate portion 31 and the second vertical plate portion 32 below the plate portion 2 are formed so as to extend toward the outer edge where they are not formed. Since both the first vertical plate portion 31 and the first spring portion 4 have plate surfaces parallel to the virtual axis C, the first vertical plate portion 31 and the first spring portion 4 can be easily formed by simple bending, and can be arranged with high space efficiency. .

The central portion of the first spring portion 4 passes through the opening 2 h of the horizontal plate portion 2, and the upper end portion 4 t (second end portion) of the first spring portion 4 is a space on the upper surface 2 b side of the horizontal plate portion 2. It extends to.

Means a space below the horizontal plate 2 as a reference.

As shown in FIG. 3, when viewed from the normal direction of the upper surface 2b of the horizontal plate portion 2, the first spring portion 4 is substantially centered on the virtual axis C from the lower end portion 4b side to the upper end portion 4t side. It is wound counterclockwise. The first spring portion 4 is wound in a rectangular shape with rounded corners.

The upper plate portion 5 is provided on the upper end portion 4t (second end portion) of the first spring portion 4. As shown in FIGS. 4 and 5, the upper plate portion 5 has a flat portion 51 and a curved surface portion 52. The flat part 51 is a part located in the center part of the upper plate part 5 and provided in parallel with the horizontal plate part 2. The curved surface portion 52 is provided in a portion of the periphery of the flat portion 51 except for the vicinity of the bent portion of the upper end portion 4t of the first spring portion 4, and is a portion extending downward from the flat portion 51 in a curved shape. is there. The upper plate portion 5 is movable in the vertical direction together with the contact portion 6 described later by elastic deformation of the first spring portion 4.

As shown in FIG. 3, the contact portion 6 is provided at the approximate center of the flat portion 51 of the upper plate portion 5. Accordingly, the position of the contact portion 6 substantially coincides with the position of the virtual axis C. As shown in FIG. 4, the contact portion 6 is provided so as to protrude upward from the flat portion 51 of the upper plate portion 5. Thereby, the contact part 6 acts as an electrical contact with the circuit board provided above the press contact 1.

The second spring portion 7 is provided so that the expansion / contraction direction intersects the lower surface 2a and the upper surface 2b of the horizontal plate portion 2 in the same manner as the first spring portion 4. The second spring portion 7 is configured by a plate body wound around the same virtual axis C as the first spring portion 4. The 2nd spring part 7 is comprised by the plate body, and as shown in FIG. 5, the shape of the cross section perpendicular | vertical to the winding direction of the 2nd spring part 7 is a rectangle. The plate is spirally wound so that the longitudinal direction of the rectangle having the above-described cross-sectional shape is parallel to the virtual axis C. Therefore, also in the 2nd spring part 7, the improvement of a spring characteristic can be aimed at for the same reason as the 1st spring part 4, and a big spring load can be added to the contact part 6. FIG.

As shown in FIG. 3, the lower end portion 7b (first end portion) of the second spring portion 7 is a side end portion (−y opposite to the side where the bent portion 321 of the second vertical plate portion 32 is provided. The first vertical plate portion 31, the second vertical plate portion 32, and the first spring portion 4 below the horizontal plate portion 2 are formed so as to extend from the end of the direction toward the outer edge where the first spring plate 4 is not formed. Yes. Like the first spring part 4, the second vertical plate part 32 and the second spring part 7 both have a plate surface parallel to the virtual axis C, and therefore can be easily formed by simple bending, and Space can be arranged efficiently.

The central portion of the second spring portion 7 passes through the opening 2h of the horizontal plate portion 2, and the upper end portion 7t (second end portion) of the second spring portion 7 extends into the space on the upper surface 2b side of the horizontal plate portion 2. Exist. When viewed from the normal direction of the upper surface 2b of the horizontal flat plate portion 2, the second spring portion 7 is wound counterclockwise about the virtual axis C from the lower end portion 7b side to the upper end portion 7t side. ing. The second spring portion 7 is wound in a rectangular shape with rounded corners. The lower end portion 4b of the first spring portion 4 and the lower end portion 7b of the second spring portion 7 are located on the same diagonal line of the pressure contact 1 when viewed from the normal direction of the upper surface 2b of the horizontal plate portion 2. .

The auxiliary plate portion 8 is provided on the upper end portion 7t (second end portion) of the second spring portion 7. As shown in FIG. 5, the auxiliary plate portion 8 is made of a flat plate material and is provided in parallel with the horizontal plate portion 2. The auxiliary plate portion 8 is arranged in parallel with the flat plate portion 51 at a predetermined interval from the upper plate portion 5. The auxiliary plate portion 8 is movable in the vertical direction by the elastic deformation of the second spring portion 7. The 1st spring part 4 and the 2nd spring part 7 are each comprised by the spring which became independent. Therefore, the upper plate portion 5 formed integrally with the first spring portion 4 and the auxiliary plate portion 8 formed integrally with the second spring portion 7 are configured to move independently.

FIG. 6 is a cross-sectional view showing a state where the pressure contact 1 is mounted between circuit boards.

Hereinafter, an example of usage of the pressure contact 1 will be described with reference to FIG. Here, an example in which two circuit boards arranged in the vertical direction are electrically connected will be described. However, the usage form is not limited to this.

When the two circuit boards are electrically connected using the pressure contact 1, the pressure contact 1 is bonded to the wiring pattern 103 of the first circuit board 101 by an arbitrary method as shown in FIG. 6. Here, the

bent portions

311 and 321 at the lower ends of the first vertical plate portion 31 and the second vertical plate portion 32 are soldered to the wiring pattern 103 so that the press contact 1 and the wiring pattern 103 are electrically connected. Is done. Further, the second circuit board 102 is disposed above the press contact 1, and the wiring pattern 104 of the second circuit board 102 is brought into contact with the contact portion 6 of the press contact 1. At this time, since the distance D1 between the two

circuit boards

101 and 102 is higher than the height T1 (see FIG. 5) of the normal pressure contact 1 (the state where no load is applied), the second circuit board 102 is an upper plate. The pressure contact 1 is pressed and arranged to a position that is lower than the interval S1 (see FIG. 5) between the portion 5 and the auxiliary plate portion 8.

Here, when the upper plate part 5 is pushed down by the second circuit board 102, the first spring part 4 is compressed. When the upper plate portion 5 is pushed down by a distance corresponding to the distance S, the upper plate portion 5 contacts the auxiliary plate portion 8. When the upper plate portion 5 is further pushed down, the auxiliary plate portion 8 is pushed down by the upper plate portion 5 and the second spring portion 7 is also compressed. Therefore, the upper plate portion 5 is pressed against the second circuit board 102 by the reaction force H of the first spring portion 4 and the second spring portion 7. In this manner, the pressure contact 1 and the wiring pattern 103 of the first circuit board 101 and the wiring pattern 104 of the second circuit board 102 are electrically and stably connected.

Hereinafter, the effect of the pressure contact 1 of the present embodiment will be described.

The pressure contact 1 includes a first spring portion 4 made of a plate body whose plate surface is perpendicular to the z direction (stretching direction F), and an upper plate portion 5 provided at the upper end of the first spring portion 4. And. Therefore, in the pressure contact 1, for example, the reaction force of the first spring portion 4 with respect to the load in the horizontal direction is small as compared with the pressure contact of the comparative example provided with a spring portion made of a plate body whose plate surface faces the horizontal direction. The upper plate part 5 is easily displaced in the horizontal direction (any direction in the xy plane). Therefore, for example, when the second circuit board 102 in FIG. 6 vibrates in the horizontal direction, the upper plate part 5 and the contact part 6 easily follow the movement of the second circuit board 102, and the contact between the contact part 6 and the wiring pattern 104. The point does not change. As a result, there is an effect that reliability of electrical connection between the pressure contact 1 and the first circuit board 101 and the second circuit board 102 can be ensured.

However, since the upper plate part 5 is easily displaced in the horizontal direction, for example, in an assembly process of an electronic device, for example, when an operator's finger is accidentally caught on the upper plate part 5, the first spring part 4 is plastic. Deformation may occur, and the function of the pressure contact 1 may be deteriorated.

In response to the above problem, the press contact 1 has a lower end formed integrally with the first vertical plate portion 31, a central portion penetrating the opening 2 h of the horizontal plate portion 2, and an upper end extending to the upper space. A first spring portion 4 is provided. With the first spring portion 4 having such a configuration, the plate surface 4d of the plate material constituting the first spring portion 4 faces the end surface 22c of the second horizontal plate portion 22 as shown in FIG.

Accordingly, as shown in FIG. 7, for example, when the finger Y is caught on the end of the upper plate portion 5, the upper plate portion receives a load in the horizontal direction (in the direction of arrow J from the right to the left in FIG. 7). 5 is displaced from the normal position (indicated by a two-dot chain line) to the left side, and the first spring portion 4 is also displaced from the normal position (indicated by a two-dot chain line) to the left side. At this time, if the displacement becomes larger than a certain distance, the plate surface 4d of the first spring portion 4 comes into contact with the end surface 22c of the second horizontal plate portion 22, and the first spring portion 4 is not displaced further. That is, the horizontal plate portion 2 functions as a stopper that restricts the movement of the first spring portion 4 over a predetermined distance.

As another countermeasure against the above problem, for example, a configuration in which a stopper is provided outside the first spring portion 4 so that the plate surface of the first spring portion 4 and the plate surface of the stopper face each other is also conceivable. However, in this case, since the horizontal load from the first spring portion 4 is received by the plate surface of the stopper, the strength of the stopper becomes insufficient when the load increases, and in some cases the first spring portion 4 However, there is a concern of plastic deformation with the stopper. On the other hand, in the case of the pressure contact 1 of the present embodiment, since the horizontal load from the first spring portion 4 is received by the end surface 22c of the second horizontal plate portion 22, even if the load increases to some extent, The horizontal plate portion 22 can sufficiently restrict the displacement of the first spring portion 4. That is, according to the present embodiment, it is possible to realize the press contact 1 that is not easily plastically deformed while ensuring the reliability of electrical connection.

Further, the press contact 1 has a lower end formed integrally with the second vertical plate portion 32, a central portion penetrating the opening 2 h of the horizontal plate portion 2, and an upper end extending to the upper space. It has. Since the second spring portion 7 has such a configuration, the plate surface 7d of the plate material constituting the second spring portion 7 faces the end surface 21c of the first horizontal plate portion 21 as shown in FIG.

Thus, even if a load is applied to the upper plate portion 5 in the direction opposite to the direction J shown in FIG. 7 (from left to right in FIG. 7), the plate surface 7d of the second spring portion 7 is the first horizontal plate portion. 21 abuts on the end surface 21c of the second spring portion 7 and the second spring portion 7 is not displaced further. Therefore, it is possible to realize the press contact 1 that is not easily plastically deformed even with a load in the direction opposite to the direction J shown in FIG.

Moreover, although the lower part (part below the horizontal plate part 2) of the 1st spring part 4 and the 2nd spring part 7 is large diameter, the circumference | surroundings were surrounded by the horizontal plate part 2 and the vertical plate part 3 Therefore, the lower portions of the first spring portion 4 and the second spring portion 7 are protected by these plate portions, and the finger or the like is not easily hit from the lateral direction or the upper direction. Also by this action, it is possible to realize the press contact 1 that is not easily plastically deformed. Further, the horizontal plate portion 2 can secure a distance from the maximum outer shape in plan view shown in FIG. 3 to the first spring portion 4 or the second spring portion 7. Therefore, it is possible to make it difficult for a finger or the like to hit the first spring portion 4 or the second spring portion 7 from the lateral direction. Moreover, since the horizontal plate part 2 is located in the middle of the height direction of the 1st spring part 4 or the 2nd spring part 7, it can make a finger | toe etc. hard to hit from a horizontal direction.

Further, in the press contact 1, the upper plate portion 5 is provided at the upper end portion 4 t of the first spring portion 4, and the contact portion 6 is provided in the flat portion 51 of the upper plate portion 5. According to this structure, compared with the case where the upper board part 5 is not provided, for example, it is easy to ensure the area of the contact part 6, and can improve the reliability of electrical connection.

The pressure contact 1 includes a second spring portion 7 and an auxiliary plate portion 8 provided on the upper end portion 7t of the second spring portion 7 so as to face the flat portion 51 of the upper plate portion 5. According to this configuration, in the state where the upper plate portion 5 and the auxiliary plate portion 8 are in contact, the load applied to the upper plate portion 5 is applied to both the first spring portion 4 and the second spring portion 7. The postures of the spring portion 4 and the second spring portion 7 are stable, and a predetermined reaction force can be ensured. Thereby, the reliability of electrical connection can be improved.

Further, in the pressure contact 1, the vertical plate portion 3 includes a first vertical plate portion 31 and a second vertical plate portion 32 that extend downward from both ends of the horizontal plate portion 2. According to this configuration, the pressure contact 1 can be stably supported on the first circuit board 101 without using another support member or the like.

Furthermore, in the pressure contact 1, the lower end 4 b of the first spring portion 4 is formed integrally with the first vertical plate portion 31, and the lower end 7 b of the second spring portion 7 is integrated with the second vertical plate portion 32. Is formed. According to this structure, the 1st spring part 4 and the 2nd spring part 7 can operate | move independently, without interfering. Thereby, the press contact 1 having a rational double spring structure can be realized.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, instead of the configuration of the above embodiment, the following configurations (1) to (6) may be adopted.
(1) In the above-described embodiment, the example in which the press contact 1 includes the two spring portions of the first spring portion 4 and the second spring portion 7 has been described. It suffices if the spring part is provided, and the second spring part is not necessarily provided. Further, the auxiliary plate portion may not be provided.
(2) In the above embodiment, the example in which the press contact 1 includes the upper plate portion 5 has been described. However, the press contact of the present invention may not include the upper plate portion. For example, the contact part which protrudes upwards may be directly provided in the upper end part of the 1st spring part.
(3) In the above embodiment, the example in which the press contact 1 includes the two vertical plate portions of the first vertical plate portion 31 and the second vertical plate portion 32 is shown, but the number of the vertical plate portions is not necessarily two. It may be any one of 1-4. Further, even when two vertical plate portions are provided, the position of the vertical plate portion does not necessarily have to be two opposite sides of the horizontal plate portion as in the above-described embodiment, but is two adjacent sides. May be.
(4) In the above-described embodiment, the example in which the press contact 1 includes two horizontal plate portions of the first horizontal plate portion 21 and the second horizontal plate portion 22 is shown, but the number of horizontal plate portions is not necessarily two. It may be any one of 1-4. For example, when the number of horizontal plate portions is 1, if there are a direction in which plastic deformation is likely to occur and a direction in which plastic deformation is unlikely to occur, the horizontal plate portion may be provided only in the direction in which plastic deformation is likely to occur. In addition, not all horizontal plate portions and all vertical plate portions are necessarily connected, and for example, some horizontal plate portions and vertical plate portions may not be connected.
(5) Further, in addition to the configuration of the above embodiment, the edge of the horizontal plate portion 2 on the opening 2h side (side closer to the first spring portion 4 and the second spring portion 7) or the opposite side to the opening 2h (first) A plate portion that rises vertically from the horizontal plate portion 2 may be provided on the edge of the first spring portion 4 and the second spring portion 7.
(6) Moreover, in the case of the said embodiment, the horizontal board part 2 is arrange | positioned in the position about 1/2 of the height of the 1st spring part 4 and the 2nd spring part 7, and the 1st spring part 4 and the 2nd The upper portion of the spring portion 7 is disposed at a position where it is exposed above the horizontal plate portion 2, but the position of the horizontal plate portion 2 is further increased so that the substantially entire first spring portion 4 and second spring portion 7 are horizontal. It is good also as a structure enclosed by the board part 2 and the vertical board part 3. FIG. In this case, in the state where the pressure contact 1 is mounted between the circuit boards, the horizontal plate 2 needs to be in a position where it does not come into contact with the circuit board 102, but the height of the vertical plate 3 is also increased. The lower ends of the part 4 and the second spring part 7 may be formed integrally with the lower part of the vertical plate part 3.

Other specific configurations regarding the number, arrangement, shape, material, and the like of each component constituting the pressure contact can be appropriately changed without being limited to the above-described embodiment. In the above embodiment, all members of the horizontal plate portion, the vertical plate portion, the first spring portion, the upper plate portion, the contact portion, the second spring portion, and the auxiliary plate portion are formed by bending one plate body. However, not all members are necessarily formed by bending a single plate. The press contact of the present invention may have a configuration in which some members are formed of other plate materials and a plurality of plate materials are joined.

As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to the said embodiment, A various deformation | transformation is possible within the range as described in a claim.
