Description

Contactor, adjustment method and manufacturing method thereof

The present invention relates to a contact for electrically connecting an object to a connected object, and a method and a method of fabricating the same.

Various electrical components necessary for ensuring the function of the machine are disposed in various electrical machines such as mobile phones. Moreover, in order to electrically connect the parts to each other (the contact object and the object to be contacted), a contactor may be used. For example, the type of the contactor is a type in which a housing formed by bending of a plate material is provided, and a type of force is applied to the protruding portion in a protruding direction by a leaf spring in the casing (hereinafter For the sake of convenience, it is called "the leaf spring type with the casing").

According to the leaf spring type contactor with the housing, the connecting object will press the protruding portion, so that a moderate contact load can be obtained by the elastic force of the spring, and the connecting object can be brought into contact with the protruding portion. Moreover, since the housing protects the spring, it is easy to manufacture a contactor which is excellent in safety.

As a leaf spring type contactor with a conventional case, for example, those disclosed in Patent Document 1 or Patent Document 2 can be cited. Patent Document 1 discloses that a series of conductive members (metal members) 1 are formed by bending, and the arc-shaped protruding portions 32 are formed from a box-shaped casing (formed by the side portion 20 or the like). ) can stand back and stand out. The protruding portion 32 functions as a protruding portion that comes into contact with the connecting object.

Patent Document 2 discloses that the contact portion 14 (projecting portion) is provided to protrude from the casing 12, and the contact portion 14 is biased in the protruding direction by the spring portion 16 (plate spring) in the casing 12. Further, in the contact portion 14, the locking portions (36, 38) formed on the both side portions thereof abut against the upper edge of the cutout portion 32 formed on the side wall of the casing 12 to prevent further jumping in the protruding direction.

Further, the leaf spring type contactor with the casing is formed such that the protruding portion protrudes in an initial state (a state before the pressing target or the like is pressed by the connection object or the like). Hereinafter, the amount of protrusion of the protruding portion at this time is referred to as "initial protrusion amount". Further, in order to stabilize the position of the protruding portion in the initial state or the like, a part of the casing is formed to support the leaf spring against the biasing force. Hereinafter, the load received by the part of the casing from the leaf spring at this time is referred to as "initial load".

As one of the product specifications of the leaf spring type contactor with a casing, the initial protrusion amount or the allowable range of the initial load (or the specification value, etc.) may be determined. At this time, for the contactor as the product, the initial protrusion amount or the initial load must be controlled within the allowable range. Further, the allowable range may differ depending on the product specifications or use of the contactor, the arrangement procedure of the connection target, or the user's request.

In order to separately supply the articles having different allowable ranges, it is necessary to adjust the initial amount of protrusion or the initial load by some countermeasures to control within the respective allowable ranges. As one of the countermeasures, it is considered to prepare plates (materials of contactors) having different shapes and the like in accordance with each product specification. For example, in the case of the one disclosed in Patent Document 2, as the plate material shown in Fig. 4(a), the position, shape, or size of the notch portion 32 or the locking portions (36, 38) and the like are prepared. Consistent multiple sheets can be selected according to the required product specifications.

However, in such a countermeasure, when there are relatively large variations in product specifications, it is not preferable to prepare a sheet material that matches each change from the viewpoint of manufacturing cost, management burden, and the like. Further, in the case where it is necessary to complete a new specification product within a short delivery time, it is necessary to appropriately prepare for the preparation of the sheet material in accordance with the specification.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a contactor and a contactor which are manufactured by using a leaf spring type which is attached to a casing, and which is not required to prepare a plate having a different shape or the like, and which is easy to adjust an initial amount of protrusion or an initial load.

According to the structure, the protrusion can be adjusted without deforming the outer casing of the casing The amount can maintain a predetermined outer shape and can change the amount of protrusion of the protruding portion, so that a highly versatile contactor corresponding to a multi-purpose can be manufactured. Moreover, the front wall portion and the protruding portion are in the same direction, and the area on the plane can also be increased, so that the shape and position of the plane do not change regardless of the amount of protrusion of the protruding portion, and therefore, the contactor can be moved. In the case of the vacuum suction adsorption portion or the like, the transportation unit is provided, and the manufacturing is simplified and the operation is simplified.

(8) Moreover, the adjustment method of the contactor of the present invention is set to a method of adjusting the initial protrusion amount of the protruding portion by the depth of the bending when manufacturing the contactor of the structure Or the initial load that the support sheet receives from the extension. According to the method, it is not necessary to prepare a plate having a different shape or the like, and it is easy to adjust the initial protrusion amount or the initial load for the leaf spring type contactor with the casing.

(9) Further, the method of manufacturing the contactor of the present invention is a method of manufacturing a contactor of the above structure, comprising: determining a set value of the depth of the bending in advance, based on a step of forming the contactor by the set value; a step of measuring an initial protrusion amount of the protruding portion or an initial load received by the support piece from the leaf spring portion with respect to the formed contactor And a step of modifying the set value based on a result of the measuring; and manufacturing the contactor based on the corrected set value. According to the method, it is possible to manufacture a case-type leaf spring type contactor having an appropriate initial protrusion amount or initial load without preparing a plate having a different shape or the like.

The contactor according to the present invention, although it is a leaf spring type with a casing, It is necessary to prepare different sheets such as shapes, and it is easy to adjust the initial amount of protrusion or initial load to manufacture. Moreover, according to the adjustment method of the contactor of the present invention, it is not necessary to prepare a plate material having a different shape or the like, and it is easy to adjust the initial protrusion amount or the initial load for the leaf spring type contactor with the casing.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in the following description, each of the up-and-down, left-right, and front-rear directions (direction orthogonal to each other) is as shown in FIG. 1 and the like.

[Overall structure of the contactor]

Fig. 1 is an external perspective view of the contactor X of the embodiment, and Fig. 2 is a perspective view showing the left half of the contactor X cut away (the same view as Fig. 1). 3 and FIG. 4 are external perspective views of the contactor X viewed from a different viewpoint from the case of FIG. 1, respectively.

The contactor X is integrally formed with a case portion 1, a leaf spring portion 2, and a protruding portion 3 by bending a piece of a conductive plate material (for example, a metal plate material made of stainless steel (SUS301 or the like)). A leaf spring type contactor with a housing. Further, the contactor X is extremely miniaturized, for example, so as to be mountable in a portable communication terminal or the like, and the size in each direction is about 1 mm to 3 mm.

The respective configurations of the contactor X will be described with reference to the respective drawings of Figs. 1 to 4 . The casing portion 1 has a left wall portion 11, a rear wall portion 12, a front wall portion 13, a right wall portion 14, a left lower wall portion 15L, and a right lower wall portion 15R, and is formed as a frame that accommodates a substantially rectangular parallelepiped of the leaf spring portion 2. Body shape (wherein, as shown in each figure, each part is open).

In other words, the left wall portion 11 is disposed so as to become the left wall as viewed from the leaf spring portion 2, and the rear wall portion 12 is disposed to be the rear side wall, and the front wall portion 13 is formed as the front side wall. In the arrangement, the right wall portion 14 is disposed so as to become a wall on the right side, and each of the lower wall portions (15L, 15R) is disposed so as to be a lower wall.

The rear wall portion 12 is formed by bending an edge from the rear side of the left wall portion 11 at a right angle, and the front wall portion 13 is formed by bending an edge from the front side of the left wall portion 11 at a right angle, and the right wall portion 14 is formed from the rear wall portion. The edge on the right side of 12 is bent at a right angle to form. Further, the left lower wall portion 15L is formed by bending the edge from the lower side of the left wall portion 11 at a right angle, and the right lower wall portion 15R is formed by bending the edge from the lower side of the right wall portion 14 at a right angle.

A convex portion 13b is provided at an edge on the right side of the front wall portion 13, and the convex portion 13b is fitted into the concave portion 14a provided at the edge on the front side of the right wall portion 14. The edge on the right side of the front wall portion 13 is also firmly fixed to the edge of the front side of the right wall portion 14 by the fitting in addition to the joining method such as welding. Further, the edge on the right side of the left lower wall portion 15L and the edge on the left side of the right lower wall portion 15R are brought close to each other in a face-to-face manner. The lower wall portions (15L, 15R) function as walls that block the substantially front half of the lower side of the casing portion 1.

At each of the upper and lower ends of the right and left ends of the rear wall portion 12, an expansion portion 12a that extends so as to expand the rear wall portion 12 to the left and right is provided. Among the four expanded portions 12a, a portion corresponding to the notched portion Sp of the left wall portion 11 or the right wall portion 14 corresponding thereto remains as a part of the rear wall portion 12. That is, the plate material before the formation of the contactor X is provided with a slit along the edge of the notch portion Sp, and even if the bending process is performed between the rear wall portion 12 and the left wall portion 11 and the right wall portion 14, the expansion portion 12a does not It is bent and remains as a part of the rear wall portion 12. The expansion portion 12a functions to expand the area of the rear wall portion 12 for adhering to the object to be connected, and to facilitate the adhesion.

The edge on the lower side of the front wall portion 13 and the front side of each of the lower wall portions (15L, 15R) Between the edges, an opening portion 17 that opens toward the front is formed. The opening portion 17 is an edge (left and right extending) on the lower side of the front wall portion 13, an edge on the front side of the left wall portion 11 (extending vertically), and an edge (left and right extension) and a right wall portion on the front side of each of the lower wall portions (15L, 15R). 14 A rectangular shaped area surrounded by the edge of the front side (extending up and down). It can be seen that the surface of the front wall portion 13 is located on substantially the same plane as the opening portion 17.

At a portion on the lower side of the front wall portion 13, a part of the front wall portion 13 is bent rearward to form a support piece 18. The structure, function, and the like of the support sheet 18 will be described in detail.

From the lower end of the rear wall portion 12, the strip-shaped portion (the width direction coincides with the left-right direction) extends as shown in FIG. 2 in a curved shape at each portion. In this portion, the leaf spring portion 2 and the protruding portion 3 are sequentially formed from the side close to the rear wall portion 12.

The leaf spring portion 2 extends so as to be turned forward from the one end connected to the rear wall portion 12. In other words, the leaf spring portion 2 is formed to extend from the lower end of the rear wall portion 12 and to be viewed when viewed from the inside in the width direction of the inside of the casing portion 1. More specifically, the leaf spring portion 2 is formed by sequentially connecting the lower turn portion 21, the rear straight portion 22, the upper turn portion 23, and the front straight portion 24 from the lower end of the rear wall portion 12.

The lower turn portion 21 is a portion that is bent in a U-shaped manner so as to be substantially semicircular from the lower end of the rear wall portion 12 when viewed in the width direction. The rear straight portion 22 is a portion that straightens upward from the end portion of the lower side turning portion 21 when viewed in the width direction. The upper side turning portion 23 is a portion that is bent in a U-shaped manner when the end portion of the rear rectilinear portion 22 is viewed from the front end portion of the rear rectilinear portion 22 when viewed in the width direction. Minute. The front straight portion 24 is a portion that straightens downward from the end portion of the upper side turning portion 23 when viewed in the width direction.

The front straight portion 24 is disposed directly behind the front wall portion 13. Further, as shown in FIG. 2, as shown in FIG. 2, a portion extending toward the front when viewed in the width direction is formed integrally, and a U-bend portion is formed so as to draw a substantially semicircle downward, and The part that extends toward the later side. In this way, the portion that protrudes toward the front becomes the protruding portion 3. The protruding portion 3 has a substantially U-shape that is convex toward the front side when viewed in the width direction (left-right direction), and the portion located at the foremost portion (front end) is a portion intended to be in contact with the connection target. Further, the amount by which the protruding portion 3 protrudes forward from the opening portion 17 (the amount protruding from the casing portion 1) is the amount by which the protruding portion 3 protrudes.

In addition, a portion from the rear straight portion 22 to the front straight portion 24 has a U-shaped portion that is substantially U-shaped when viewed in the left-right direction (width direction). The U-shaped portion is formed such that the front straight portion 24 and the end portion on the upper side of the rear straight portion 22 parallel to the rear side thereof are connected to each other to have a substantially U shape. Since the plate spring portion 2 has a shape of a ridge including such a U-shaped portion, it has stable elasticity as compared with a case where the shape is, for example, a cantilever beam, and the range of movement of the protruding portion 3 that exhibits an appropriate contact force can be expanded. (working area).

As described above, the leaf spring portion 2 is connected to the casing portion 1 (more specifically, the rear wall portion 12) at one end, and the protruding portion 3 is connected to the other end. In the protruding portion 3, the portion on the front side protrudes forward from the opening portion 17, and in the initial state (in the state in which the protruding portion 3 is not pushed rearward, the same applies hereinafter), the amount of protrusion is maximized. When the front end of the front portion of the protruding portion 3 is pressed rearward by the connection object or the like, the protruding portion 3 is correspondingly directed toward It moves to the inside of the casing part 1. Further, the leaf spring portion 2 is provided inside the casing portion 1, and functions as a leaf spring that urges the protruding portion 3 toward the front.

Further, in the initial state, the front straight portion 24 presses the support piece 18 forward by the action of the leaf spring. In other words, the support piece 18 supports the front straight portion 24 against the urging force in the initial state. When the front end of the protruding portion 3 is pushed rearward by the connection object or the like from this state, the leaf spring portion 2 is deflected, and the protruding portion 3 is retracted toward the inside of the casing portion 1. The leaf spring portion 2 functions to urge the protruding portion 3 forward, and the force of the biasing force increases in accordance with the amount of deflection of the leaf spring portion 2 (in other words, the amount of movement of the protruding portion 3 toward the rear).

Further, the casing portion 1 functions to accommodate the plate spring portion 2 from being protected from external collision or foreign matter adhesion. The lower end (lower side turn portion 21) of the leaf spring portion 2 does not protrude beyond the end surface of the opening portion on the lower side of the casing portion 1, so that it can be effectively protected from object collision or the like. The upper end (upper turn portion 23) of the leaf spring portion 2 does not protrude beyond the end surface of the opening portion on the upper side of the casing portion 1, so that it can be effectively protected from object collision or the like. In order to make this protection more sufficient, the casing portion 1 may also form a wall portion on the rear side and the upper side (or one of the ones) on the lower side thereof.

Further, between the leaf spring portion 2 and the left wall portion 11 and between the leaf spring portion 2 and the right wall portion 14, a proper gap is secured so that the leaf spring portion 2 is not rubbed to the left wall portion 11 or the right wall portion 14 Blocking movement. The contactor X has the above-described configuration and functions as a component for electrically connecting the connection object that is in contact with the distal end contact portion 31 to the object to be connected.

[Usage form of contactor]

Next, the use form of the contactor X will be described. The contactor X is provided, for example, in an electric device such as a portable communication device, and functions to electrically connect components such as a circuit board to each other. 5(a) and 5(b) show an example of a case where the contact object Ob1 is used to electrically connect the connection object Ob1 (one of the connected components) to the object to be connected Ob2 (the other component to be connected). 6(a) and 6(b), the case shown in FIG. 5(a) and FIG. 5(b) is observed from another viewpoint (left viewpoint).

In the contactor X, the rear surface of the rear wall portion 12 of the casing portion 1 serves as a mounting surface, and as shown in Fig. 5(a), the surface is adhered and fixed to the object to be joined Ob2. When the adhesion is fixed, for example, welding or the like can be used. Thereby, the casing portion 1 is electrically connected to the connected object Ob2. Further, the front surface of the front wall portion 13 is a flat adsorption surface (a surface to be adsorbed by a predetermined working device), and the contactor X is conveyed by the device and positioned to the object to be connected Ob2, as described above. It is fixed by adhesion.

When the connection object Ob1 is electrically connected to the object to be connected Ob2 from the state shown in FIG. 5(a), the connection object Ob1 is moved rearward, and the connection object Ob1 is placed as shown in FIG. 5(b). In this already arranged state, as is clear from FIG. 6(b), the front end of the protruding portion 3 of the contactor X is pressed from the front by the connection object Ob1. As a result, the protruding portion 3 retreats in response to the pressing, and at the same time, the leaf spring portion 2 is deflected toward the rear.

The plate spring portion 2 biases the protruding portion 3 toward the front by the elastic force, so that the protruding portion 3 presses the connection object Ob1 with an appropriate force, thereby obtaining the protrusion. The portion 3 is in stable contact with the connection object Ob1. Since the contactor X is entirely formed of a conductive material, the connection object Ob1 that is in contact with the protruding portion 3 is electrically connected to the object to be connected Ob2.

Further, as a program for arranging the connection object Ob1, in addition to the programs shown in FIG. 5(a), FIG. 5(b) or FIGS. 6(a) and 6(b), for example, FIG. 7(a) and FIG. 7(b), the procedure shown in Figure 7(c). In the routines shown in Fig. 7 (a), Fig. 7 (b), and Fig. 7 (c), first, as shown in Fig. 7 (a), the connection object Ob1 is moved laterally (direction orthogonal to the front-rear direction). At this time, the position in the front-rear direction of the connection object Ob1 is slightly (for example, about 0.05 mm) on the front side of the front end of the protruding portion 3. Therefore, the connection object Ob1 moves laterally while maintaining a distance that is barely in contact with the front end of the front portion of the protruding portion 3.

After the connection object Ob1 is moved to the position shown in FIG. 7(b), the connection object Ob1 is moved backward, and the connection object Ob1 is placed as shown in FIG. 7(c). Thereby, as in the case of FIG. 5(b), stable contact of the protruding portion 3 with the connection object Ob1 can be obtained, and the connection object Ob1 is electrically connected to the connected object Ob2. In the case of the procedure shown in Fig. 7 (a), Fig. 7 (b), and Fig. 7 (c), Fig. 5 (a), Fig. 5 (b) or Fig. 6 (a), Fig. 6 (b) In comparison with the case shown, the space required to arrange the connection object Ob1 in front of the contactor X can be greatly reduced.

[Initial protrusion or initial load adjustment]

The contactor X of the present embodiment can adjust the amount of protrusion of the protruding portion 3 in the initial state by the depth of the bending of the support piece 18, or support the piece in the initial state. 18 The load received from the front straight portion 24. In the following description, the depth of the bending of the support piece 18 may be simply referred to as "bending depth", and the amount of protrusion of the protruding portion 3 in the initial state may be referred to as "initial protrusion amount", and will be in an initial state. The load that the support sheet 18 receives from the front straight portion 24 is referred to as an "initial load." The principle of adjustment of the initial protrusion amount or the initial load will be described below with reference to FIGS. 8(A), 8(B), and 8(C).

8(A) to 8(C) are cross-sectional views of the contactors X when the bending depth is changed (corresponding to the view of FIG. 2 from the left). As shown in the figure, in terms of the bending depth, the bending depth d1 in FIG. 8(A) is the smallest, and becomes the bending depth d2 in FIG. 8(B) and FIG. 8(C). The bending depth d3 becomes larger. However, in any case, it is unchanged that the front end of the support piece 18 overcomes the biasing force to support the leaf spring portion 2 (the front straight portion 24). Further, the width dimension or the like of the support sheet 18 is appropriately set in consideration of the thickness or material of the front wall portion 13, so as not to be pressed by the front straight portion 24, and it is easy to recover by bending.

The bending depth (in the present embodiment, the angle at which the support sheet 18 is bent) can be made larger, in other words, the closer the angle between the front wall portion 13 and the support piece 18 is to the right angle, the front end of the support sheet 18 is provided. The position becomes rearward. Therefore, the position of the front straight portion 24 supported by it is restricted to be further rearward, and the position of the protruding portion 3 connected to the front straight portion 24 is also restricted to be further rearward.

Further, the position of the protruding portion 3 is restricted to be further rearward, and the initial protruding amount is smaller. 8(A), 8(B), and 8(C), the initial protrusion amount h1 in FIG. 8(A) is the largest, and becomes the initial protrusion in FIG. 8(B). The amount h2 is smaller as the initial amount of protrusion h3 in Fig. 8(C).

On the other hand, if attention is paid to the initial load, the characteristics of the leaf spring portion 2 are common in any case, and therefore, according to Hooke's law, the greater the amount of deflection, the elastic force of the leaf spring portion 2 ( The force exerting the force toward the front is greater. When the position of the front straight portion 24 is further rearward, the amount of deflection of the leaf spring portion 2 is also increased, and the elastic force is also increased.

The support piece 18 receives the elastic force as an initial load, and therefore the greater the bending depth, the larger the initial load. In the example shown in Fig. 8(A), Fig. 8(B), and Fig. 8(C), the initial load F1 in Fig. 8(A) is the smallest, and becomes the initial load F2 in Fig. 8(B). The initial load F3 in Fig. 8(C) becomes larger. As described above, the contactor X can adjust the initial amount of protrusion or the initial load by the bending depth. Further, the initial amount of protrusion is adjusted, for example, to a value of about 0.6 mm, and for the initial load, for example, a value of several hundred mN is adjusted.

In the step of forming the contactor X by the bending of the sheet material, the bending depth is determined to be an arbitrary value when the front wall portion 13 is bent to form the support sheet 18. Here, the case where the support piece 18 is formed will be described in more detail with reference to FIGS. 9(A) and 9(B).

FIG. 9(A) is a view schematically showing a case where the front wall portion 13 is subjected to the cutting and bending process for forming the support sheet 18 by the front viewpoint. Further, Fig. 9(B) is a cross-sectional view showing a state in which a portion indicated by a one-dot chain line m is cut in Fig. 9(A). With respect to the front wall portion 13, as the cutting and bending process for forming the support piece 18, the cutting process at the line L2 shown on the left side of FIG. 9(A) and the bending at the line L1 are simultaneously performed. Folding treatment.

Thereby, the portion from the line L1 to the edge 13a on the lower side of the front wall portion 13 is inclined rearward. In addition, the portion (the portion sandwiched by the respective lines L2) of the support sheet 18 is set to the lower portion of the front wall portion 13 in consideration of the fact that the support sheet 18 can support the leaf spring portion 2 and the like with good balance on the left and right sides. The fixed area in the center of the left and right direction.

As a result of performing the cutting and bending process, as shown in the right side of FIGS. 9(A) and 9(B), a portion inclined rearward from the original state is formed as the support piece 18. As is clear from the figure, a part of the edge 13a on the lower side of the front wall portion 13 becomes the front end portion 18a of the support piece 18 by this processing. Further, since the cutting and bending process is performed, the left and right side portions of the support sheet 18 are easily brought into contact with the front wall portion 13 in the vicinity of the bent root portion, and friction is likely to occur therebetween, and accordingly, the support sheet 18 can be restrained. The spring portion 2 is pressed and moved.

However, as a form in which the support piece 18 is formed in the front wall portion 13, for example, as shown in FIG. 10, a slit along the left and right side portions of the support piece 18 may be provided in the front wall portion 13 in advance. The usual bending process is performed along the line L1 which is bent at a predetermined time. At this time, the cutting process at the line L2 can be omitted, and accordingly, the step for forming the support sheet 18 itself is simplified.

Further, the line L1 bent when the support piece 18 is formed is parallel to the direction (left-right direction) in which the edge 13a on the lower side of the front wall portion 13 extends. Further, the line L1 is orthogonal to the direction (lower direction) in which the front straight portion 24 of the leaf spring portion 2 extends. Therefore, the front end portion 18a of the support piece is dimensioned regardless of the bending depth. Further, the extending direction of the distal end portion 18a coincides with the width direction (left-right direction) of the front straight portion 24 regardless of the bending depth.

Thereby, the front end portion 18a uniformly contacts and supports the front straight portion 24 in the width direction regardless of the bending depth. As a result, the front end portion 18a can stably support the front straight portion 24.

Further, the initial protruding amount in the contactor or the specification (allowable range) of the initial load may be different depending on, for example, the product specifications or use of the contactor, the configuration procedure of the connection target, or the user's request. According to the contactor X of the present embodiment, even if the initial projection amount or the initial load specification is different, the initial projection amount or the initial load may be adjusted by the bending depth in a manner suitable for each specification.

Therefore, it is not necessary to prepare different types of sheets in order to conform to the respective specifications, and it is possible to manufacture products suitable for various specifications by performing bending processing on the same sheets. Further, as long as the bending depth is changed, it is possible to match the respective specifications. Therefore, if a manufacturing apparatus for the contactor X having a variable bending depth is used, it is possible to manufacture products suitable for each specification by using the manufacturing apparatus.

Further, for example, when the program shown in FIG. 7(a), FIG. 7(b), and FIG. 7(c) is employed for the configuration of the connection object Ob1, it is important to adjust the initial amount of protrusion to the allowable range to avoid the connection object. The Ob1 collides from the lateral direction to the protrusion 3. Even in such a case, in the present embodiment, since the initial amount of protrusion can be adjusted by the bending depth, it is easy to appropriately respond.

Moreover, the initial load affects the stability of the position of the projection 3. Therefore, especially in the case of paying attention to this point, it is important to adjust the initial load to the allowable range. When the initial load is too small, the protruding portion 3 vibrates due to a weak impact or the like, and the position thereof tends to be unstable. When the contactor X is temporarily used to largely retreat the protruding portion 3, the deformation of the leaf spring portion 2 exceeds the elastic deformation to plastically deform, and even if the contact object Ob1 is removed, the leaf spring portion 2 remains extended (stress-deformation relationship occurs). Hysteresis, so sometimes the appropriate initial load cannot be obtained.

In order to prevent such a phenomenon, it is important to increase the initial load in advance so that the initial load is controlled within the allowable range even after the leaf spring portion 2 is extended. Even in such a case, in the present embodiment, since the initial load can be adjusted by the bending depth, it is easy to appropriately respond.

[Method of Manufacturing Contactor with Appropriate Adjustment]

As described above, in the present embodiment, the initial projection amount or the initial load can be adjusted by changing the bending depth of the support piece 18. In addition, in the following description, either one of the initial amount of protrusion and the initial load may be referred to as an "adjustment target". The method of manufacturing the contactor X for appropriately adjusting the adjustment target will be described below with reference to the flowchart shown in FIG.

First, based on the target value Va of the adjustment target (generally, the approximate central value of the allowable range), the set value Vb of the bending depth (the target value at the time of the bending process) is determined (step S1). In other words, by calculating the experience or the like so far, it is possible to predict the degree to which the bending depth is to be the target value Va. Therefore, the predicted value is first determined as the set value Vb.

Next, a predetermined number of contactors X are manufactured based on the current set value Vb (that is, the target of the bending depth is set to the set value Vb) (step S2). Then, with respect to the manufactured contactor X, the adjustment target is measured (step S3). When the adjustment target is the "initial protrusion amount", for example, the distance from the surface of the front wall portion 13 to the front end of the protrusion portion 3 is measured. When the adjustment target is "initial load", for example, the front side is pressed. The force required to move the projection 3 is measured.

If the measured value thus obtained is within the allowable range (Yes in step S4), the current set value Vb has no problem, and therefore, the contactor X is manufactured based on the current set value Vb (step S5). On the other hand, if the measured value is out of the allowable range (No in step S4), the set value Vb is corrected so that the measured value approaches the target value Va (step S6).

Specifically, when the adjustment target is the "initial protrusion amount", if the measured value exceeds the allowable range, in order to eliminate this problem, it is only necessary to increase the bending depth, and thus the set value Vb is raised. On the other hand, if the measured value is lower than the allowable range, in order to eliminate this problem, it is only necessary to reduce the bending depth, and thus the set value Vb is lowered.

Further, when the adjustment target is the "initial load", if the measured value exceeds the allowable range, in order to eliminate this problem, it is only necessary to reduce the bending depth, and thus the set value Vb is lowered. On the other hand, if the measured value is lower than the allowable range, in order to eliminate this problem, it is only necessary to increase the bending depth, and thus the set value Vb is raised.

After the set value Vb is corrected, the corrected set value Vb is regarded as the current set value Vb, and the steps from the step S2 onwards are repeated. So, this In the manufacturing method, the following steps are performed: the set value Vb of the bending depth is determined in advance, and the contactor X is formed based on the set value Vb; the adjustment target is measured for the formed contactor; and the set value is corrected based on the measurement result Vb; and the contactor X is manufactured based on the corrected set value Vb (however, in the case where there is no problem at the beginning of the measurement result, no correction is required). In the present manufacturing method, the set value Vb is corrected by applying a feedback method until the measured value of the adjustment target is within the allowable range. As a result, the contactor X whose adjustment target has been controlled within the allowable range can be manufactured.

[Overall]

As described above, the contactor X of the present embodiment includes the case portion 1 formed by bending of a plate material, and an extending portion (formed with a protruding portion 3 that protrudes forward and a protruding portion 3 that faces forward) a portion of the force plate spring portion 2, one end of which is coupled to the housing portion 1; and a support piece 18 for supporting the extension portion at the front end portion 18a against the urging force, and inclined in a manner to be inclined rearward A predetermined portion of the casing portion 1 is formed by bending, and the connection object Ob1 that is in contact with the protruding portion 3 is electrically connected to the object to be connected Ob2.

Therefore, the contactor X is a leaf spring type with a casing, but it is not necessary to prepare a plate having a different shape or the like, and it is easy to adjust the initial amount of protrusion or the initial load to manufacture. That is, with the contactor X, even if the same plate material is used, the contact amount X can be adjusted by adjusting the initial protrusion amount or the initial load as long as the bending depth of the support piece 18 is changed.

As a result, even if there is a relatively large change in the product specifications related to the initial amount of protrusion or the initial load, it is not necessary to separately prepare for the change. Sheets are advantageous in terms of manufacturing costs or management burden. Further, even in the case where it is necessary to complete the new specification product within a short delivery time, it is not necessary to adjust the bending depth of the support sheet 18 in the preparation period of the sheet material which is consistent with the specification, which is advantageous.

Further, in the contactor X, the casing portion 1 has a front wall portion 13 whose front surface faces forward, and a plate spring portion which extends at least a portion along the rear surface of the front wall portion 13 in the downward direction 2. A protruding portion 3 that protrudes forward from the front surface is connected to a position that is advanced toward the lower side of the front wall portion 13. Further, the support piece 18 is formed such that the edge 13a of the front wall portion 13 facing the protruding portion 3 becomes the front end portion 18a, and the line L1 of the front wall portion 13 is bent.

Thus, the contactor X has the front wall portion 13 which protects the leaf spring portion 2 from the collision of an object from the front, and the like, and can also be used as an adsorption surface when the contactor X is moved to move. Further, in the present embodiment, a part of the front wall portion 13 is bent to form the support piece 18, and the front wall portion 13 is more effectively used. In particular, the edge 13a of the front wall portion 13 facing the protruding portion 3 serves as the front end portion 18a of the support piece, so that the leaf spring portion 2 can be supported at a position very close to the protruding portion 3, so that the position of the protruding portion 3 can be easily stabilized.

However, it is also possible to adopt a form other than the present embodiment with respect to the position at which the support piece is provided, the shape of the support piece, and the like. For example, the vicinity of the edge on the right side of the front wall portion 13 may be bent rearward, and the support piece 18 may be replaced by the portion. Further, for example, the vicinity of the edge of the front side of the left wall portion 11 or the right wall portion 14 may be bent toward the inside of the casing portion 1 by more than 90 degrees, and the support piece 18 may be replaced by the portion. At this time, even if the front wall portion is omitted The formation of 13 can also be provided with a support sheet.

Further, an extending portion that protrudes downward may be provided in advance at an end portion of the lower side of the protruding portion 3 (the side where the leaf spring portion 2 is not connected), and the extending portion may be supported by the support piece. In this case, the vicinity of the edge of the front side of the left wall portion 11, the right wall portion 14, or the lower wall portion (15L, 15R) is bent toward the inside of the casing portion 1 by more than 90 degrees, so that the portion can be a support piece. .

Further, in the conventional contactor, a part of the outer shape of the casing may be used as the load piece for the protruding portion. However, in the case of this configuration, the outer shape of the casing may exist when the protruding portion is adjusted. There will be a problem of deformation. On the other hand, according to the present embodiment, it is also possible to provide a contactor that can maintain the outer shape of the casing and adjust the amount of protrusion of the protruding portion, and an adjustment method and a manufacturing method thereof.

That is, the contactor X includes: a casing portion 1 which is formed by at least a tubular side wall by bending of a sheet material; and an extending portion which is connected at one end to the casing portion 1 and extends in the casing portion 1 in the cylinder direction, and The contact portion formed on the free end side protrudes to the front side from the side wall (front wall portion 13) on the front side of the casing portion 1 by an elastic force, and a regulating piece is formed on a part of the front wall portion 13 (supported) In the sheet 18), the tab (the support sheet 18) abuts against the extending portion to adjust the amount of protrusion of the contact portion, and is relatively bendable relative to the front wall portion 13.

Therefore, the amount of protrusion can be adjusted without deforming the outer casing of the casing, and the predetermined outer shape can be maintained, and the amount of protrusion of the protruding portion can be changed, so that a versatile contact corresponding to multi-purpose can be produced. Device. Moreover, the front wall portion 13 and the protruding portion 3 are in the same direction, and the area on the plane can also be increased, regardless of the protrusion of the protruding portion 3. The shape and the position of the plane do not change, so that the vacuum suctioning portion and the like when the contactor is moved can be provided with the conveying portion, and the manufacturing is simplified and operated. simplify.

The configuration of the present invention may be variously modified without departing from the spirit and scope of the invention. That is, the embodiments are merely illustrative in all respects and should not be considered as limiting. It is to be understood that the technical scope of the present invention is defined by the scope of the claims and not the description of the embodiments.
