Description

contact

The present invention relates to a contact used for electrical connection of a connection target and a connection target.

Various electric devices such as a mobile phone are provided with various parts necessary for ensuring the function of the device. In addition, a contact may be used to electrically connect these components (a connection target and a connection target).
There are various types of such contacts, but one type of the contacts disclosed in Patent Document 1 with the smallest number of parts is known. This contact is formed by punching a single conductive plate material into a predetermined shape and bending it. As shown in FIGS. 1 to 3 of Patent Document 1, the contact portion 14 having an inverted U-shape is formed from the housing 12. (Protrusions) are provided so as to project, and the contact portions 14 (protrusions) are urged in the projecting direction by the spring parts 16 (plate springs) in the housing 12. (A type in which the contact portion 14 (projection portion) formed by bending a conductive plate material having a predetermined shape and urged in this manner is biased in the projection direction by the spring portion 16 (plate spring) is hereinafter referred to as “ This is called a “folding-type protrusion urging type”.)

In the “folded protrusion urging type” contact, since the contact portion 14 (protrusion portion) is urged in the protrusion direction by the spring portion 16 (plate spring), the connection target is the contact portion 14 (protrusion portion). The contact portion 14 made of a belt-like plate material is connected so as to push the contact portion 14 from the front face of the belt, and an appropriate contact load is obtained by the elastic force of the spring portion 16 (plate spring). It can be connected. (The form in which the connection target is approached from the front of the contact portion is referred to as the front approach form for convenience.)

JP-A-2015-46229

For example, in the manufacturing process of an electric device, the contact of the contact is accidentally caused when another component hits the side surface of the contact portion 14 in the width direction (direction perpendicular to the biasing direction of the spring portion 16). The contact portion may be positioned in the width direction or may be deformed. In particular, when the contact is miniaturized, the plate thickness is also reduced, and this tendency is promoted.

Further, even when the contact object is moved in the width direction and approached to the side surface of the protrusion, there is a risk of causing the same situation as in the case of the component, and the contact is used to approach and connect the connection object from the width direction. Not used in form.
In the present application, the direction facing the side wall of the protruding portion is referred to as the “width direction”. Of the width direction, the direction approaching the protruding portion is “inward in the lateral direction” and the direction away from the protruding portion is “outward in the lateral direction”. May be called.

Furthermore, since the electrical connection of the connection target and the connection target becomes a conductive path through the S-shaped leaf spring 16 having a bent portion, the electrical length of the conductive path is increased accordingly. This is a factor that causes a reduction in high-frequency characteristics in applications such as antenna feeding.

The present invention has been made in view of the above-described problems, and is only a configuration in which the connection target approaches and connects from the front of the protruding portion (referred to as a front approaching configuration) while being a “folding-type protruding portion biasing type”. Instead, an object is to provide a contact that can be used as a form in which a connection target is approached and connected from the width direction of the protrusion.
In addition, among the forms in which the connection target is connected to the bent protrusion-type biased contact, the form in which the connection target is approached inward in the lateral direction to the side wall of the protrusion may be referred to as a “side approaching form”. is there. In the side approach mode, the connection object advances in the lateral direction so as to push away the side wall of the protruding portion, and the protruding portion can be moved backward by the amount pushed away.

Another object of the present invention is to provide a contact that can stably form a conductive path that can shorten the electrical length.

The contact according to the present invention includes a housing, a protrusion protruding from the opening of the housing and contacting a connection target, and being accommodated in the housing, and having a free end connected to the protrusion and extending the protrusion in the protruding direction. In the contact formed by bending a single conductive plate, the spring portion to be urged, the protruding portion forms a side wall portion on the free end side, and a guide side wall portion branches in each width direction. The one guide side wall portion extends in a direction opposite to the protruding direction, and at least a free end portion thereof is configured to elastically slidably contact the inner wall surface of the housing. According to this configuration, the connection target can be used as a form of approaching and connecting from the width direction of the protruding portion, and a conductive path that can shorten the electrical length can be stably formed.

More specifically, as the above configuration, an engaging portion is provided on the protruding portion side, and the engaging portion engages with a portion on the housing side, whereby at least one direction orthogonal to the protruding direction is provided. It is good also as a structure by which the displacement of the said protrusion part is suppressed. Here, the “projection part side” means the side of the projection part when viewed from the spring part, and the “housing side” means the side of the housing when viewed from the spring part.

More specifically, as the above configuration, the engaging portion having the protrusion in the width direction is provided to extend from the side wall portion of the protruding portion, and the protrusion engages with the portion on the housing side. It is good. More specifically, as the configuration, the protrusion may be fitted in a hole provided in the housing, and may be configured to engage with an edge of the hole. More specifically, the hole may be formed in an arc shape.

Further, in the above configuration, the housing is provided with an inclined portion that is inclined so as to go inward of the housing as it proceeds in the opposite direction, and at least one of the guide side wall portions slides elastically on the inclined portion. It is good also as a structure which touches. More specifically, the inclined portion may be configured such that a part of the housing is cut and bent.

According to the contact according to the present invention, the connection target can be used as a form of approaching and connecting from the width direction of the protruding portion, and a conductive path capable of shortening the electrical length can be stably formed.

It is. In the present embodiment, a metal plate (for example, a plate made of stainless steel (SUS301 or the like)) is used as the conductive plate. By integrally forming the housing portion 1, the leaf spring portion 2, and the protruding portion 3 with a series of metal plate materials, it is not necessary to bond these parts in the manufacturing process of the contact X, and adhesion failure and the like are avoided. The contact X can be formed efficiently. The contact X is very small so that it can be mounted on a portable communication terminal or the like, and the dimension in the left-right direction is about 4 mm, and the plate material is about 0.1 mm.

The lower edge of the rear upper right wall portion 14bU and the upper edge of the rear lower right wall portion 14bD are vertically opposed to each other with a slight gap.

In addition, a hole 13a1 is provided at a position below the central portion in the left-right direction of the front front wall 13a, and a claw 13b1 is provided at a position corresponding to the hole 13a1 in the rear front wall 13b. ing. The claw portion 13b1 is provided with a rectangular cut (substantially “U” -shaped cut) excluding the lower side at the position of the rear front wall portion 13b, and corresponds to the lower side. Is formed by being bent so as to rotate forward a little with respect to the rotation axis. In the front wall portion 13, the claw portion 13 b 1 is located in the hole portion 13 a 1, and the upper edge (edge extending left and right) of the claw portion 13 b 1 faces the upper edge (edge extending right and left) of the hole portion 13 a 1. It touches.

The opening SP formed on the right side of the front wall portion 13 includes a right edge (extending vertically) of the front wall portion 13, a front edge (extending left and right) of the lower wall portion, and a front lower portion Front edge of side right wall 14aD (extends vertically), front edge of front upper right wall 14aU (extends vertically), front edge of upper wall 15 (extends horizontally) The housing part 1 is opened forward. The surface of the front wall 13 and the opening SP are located on substantially the same plane.

The leaf spring portion 2 is formed so as to extend from the right end of the rear wall portion 12. As shown in FIG. 3, the leaf spring portion 2 has a band shape (width direction coincides with the vertical direction) bent at each location, and the protruding portion 3 is connected to the end portion.

The leaf spring portion 2 extends while meandering from side to side from one end connected to the rear wall portion 12 toward the front. That is, the leaf spring portion 2 extends from the right end of the rear wall portion 12 and is formed so as to meander inside the housing portion 1 when viewed in the width direction. More specifically, the leaf spring portion 2 is formed by connecting a lower turn portion 21, a rear rectilinear portion 22, an upper turn portion 23, and a front rectilinear portion 24 in order from the right end of the rear wall portion 12. .

The lower turn portion 21 is a portion bent so as to make a U-turn by drawing a substantially semicircle toward the front from the right end of the rear wall portion 12 when viewed in the width direction. The rear rectilinear portion 22 is a portion that straightly travels to the left from the end of the lower turn portion 21 when viewed in the width direction. The upper turn portion 23 is a portion bent so as to make a U-turn by drawing a substantially semicircle toward the front from the end portion of the rear rectilinear portion 22 when viewed in the width direction. The front rectilinear portion 24 is a portion that straightly travels rightward from the end of the upper turn portion 23 when viewed in the width direction.

The front rectilinear portion 24 is disposed immediately behind the front wall portion 13. And the protrusion part 3 is connected with the right side of the front side rectilinear advance part 24. As shown in FIG. The protruding portion 3 is formed so as to protrude forward from the opening SP provided in the housing portion 1, and is a portion where contact with the connection target is planned.

As shown in the developed view of FIG. 20, the protrusion 3 includes a rectangular tip contact portion 31, a left side wall portion 32L and a right side wall portion 32R connected to the left and right sides of the rectangle, and the rectangular shape. It consists of an upper guide wall 32U and a lower guide wall 32D connected to the upper and lower sides, and is formed in a dome shape that is convex forward by bending. The rectangular tip contact portion 31 has a left and right side dimension of 0.5 mm, and an upper and lower side dimension of 0.6 mm. The left and

right side walls

32L and 32R are connected portions with the contact tip portion 31. The dimensions are 0.1mm narrower. Thereby, the bending curvature of each

guide wall part

32U and 32D can be enlarged.

The tip contact portion 31 is a portion near the front tip in the protruding direction of the protruding portion 3, and can contact a connection target located in front of the contact X. The right side wall 32R extends rearward from the right side of the tip contact portion 31 while being curved so as to swell rightward. The rear end of the right side wall portion 32R is located slightly behind the opening SP, and the front end is in a free state. The left side wall 32L extends rearward from the left side of the tip contact portion 31 while being curved so as to swell leftward. The rear end of the left side wall portion 32L is connected to the right end of the front rectilinear portion 24 in the leaf spring portion 2.
Therefore, the left side wall portion 32L, the tip contact portion 31, and the right side wall portion 32R are connected to form an inverted U-shaped protruding portion 3. Further, as shown in FIG. 4, the tip protrusion 31 has a convex cross section, and the upper side is an arcuate tip upper guide surface 31-1, and the lower side is an arcuate tip lower guide surface 31-2. .

In FIG. 1, the upper guide wall portion 32U passes through an upper curved guide portion 32U-1 that is curved so as to bulge upward from the upper side of the tip contact portion 31 along the arcuate locus of the tip guide portion 31-1. It extends to the back. The rear end of the upper guide wall portion 32U extends rearward from the opening SP, and as shown in FIG. 4, an upper convex portion 41U that slightly bulges upward in the vicinity of the rear end is provided.

In FIG. 2, the lower guide wall portion 32D passes through a lower curved guide portion 32D-1 that is curved so as to bulge downward from the lower side of the distal end contact portion 31 along the arcuate locus of the lower end guide surface 31-2. It extends to the back. The rear end of the lower guide wall portion 32D extends rearward from the opening SP, and as shown in FIG. 4, a lower convex portion 41D is provided so as to slightly bulge downward in the vicinity of the rear end. Yes. Note that the surfaces of the upper and lower

guide wall portions

32U and 32D, the left and right

side wall portions

32L and 32R, and the tip contact portion 31 are formed as a series of curved surfaces (curved surfaces that are convex forward).

In FIG. 3, an upper guide portion 42 U and a lower guide portion 42 D that guide the movement of the front rectilinear portion 24 are connected to a portion of the leaf spring portion 2 slightly to the right of the front rectilinear portion 24. As shown in FIGS. 5 and 6, the upper guide portion 42 U is formed such that a portion extending upward from the upper edge of the front rectilinear portion 24 is bent backward at the edge. The lower guide portion 42D is formed by bending a portion extending downward from the lower edge of the front rectilinear portion 24 to the rear at the edge.

As described above, the protruding portion 3 protrudes forward from the opening SP and indicates the protruding amount in an initial state (refers to a state in which the protruding portion 3 is not pushed backward. The same applies hereinafter). It has become the maximum. Further, the protruding portion 3 is biased forward by the leaf spring portion 2. When the protruding portion 3 is pushed backward by the connection target, the protruding portion 3 moves toward the inside of the housing portion 1 against the urging of the leaf spring portion 2 correspondingly. In a state where the tip contact portion 31 is pushed rearward by the connection target, the tip contact portion 31 comes into close contact with the connection target by the urging of the leaf spring portion 2, and a stable contact state between the two is obtained.

In addition, the part from the rear side rectilinear portion 22 to the front side rectilinear portion 24 forms a U-shaped portion that is substantially U-shaped when viewed in the vertical direction (width direction). The U-shaped portion is substantially U-shaped by connecting the front rectilinear portion 24 and the rear rectilinear portion 22 parallel to the rear side thereof at the left end portions. Since the leaf spring portion 2 has a meandering shape including such a U-shaped portion, the leaf spring portion 2 has a stable elasticity and exhibits an appropriate contact force as compared with, for example, a cantilever shape. The movement range (working area) of the protrusion 3 to be made can be widened.

Further, as shown in FIG. 3, the right end portion of the rear front wall portion 13b is a support portion (support piece) 13b2 bent toward the rear. In the initial state, the front rectilinear portion 24 is configured to push the right edge of the support portion 13b2 forward by the elastic force of the leaf spring portion 2. In other words, the support portion 13b2 supports the front rectilinear portion 24 against the bias of the leaf spring portion 2 in the initial state. As the bending depth (bending angle) of the support portion 13b2 is increased, the right edge of the support portion 13b2 moves rearward, so that the position of the protruding portion 3 in the initial state is rearward, and the support portion 13b2 is the front rectilinear portion 24. The load received from is increased. By utilizing this principle, for example, by changing the bending depth of the support portion 13b2 at the time of manufacturing the contact X, the protrusion amount of the protrusion portion 3 in the initial state or the support portion 13b2 in the initial state from the front rectilinear portion 24. It is possible to adjust the received load.

Also, the housing part 1 accommodates the leaf spring part 2 and plays a role of protecting from external object collision and foreign matter adhesion. The right end (right turn part 21) of the leaf spring part 2 is located on the left side of the rear upper front wall part 14bU and the rear lower front wall part 14bD, and is effectively protected from an object collision or the like. The left end (left turn part 23) of the leaf spring part 2 does not protrude outside the left end face of the housing part 1 and is effectively protected from an object collision or the like. The housing part 1 may have a wall part on the left side of the leaf spring part 2 in order to make the protection more sufficient. The contact X has the configuration described above, and functions as a component for electrically connecting the connection target that contacts the tip contact portion 31 to the connection target.

[Usage of contact]
Next, how the contact X is used will be described. The contact X is provided in an electrical device such as a smartphone (portable communication device), for example, and can electrically connect components such as a circuit board. Hereinafter, as an example of a usage form of the contact X, the contact X is attached and fixed to a substrate BD (one form of a connection target) built in the smartphone SF, and the contact X is a frame FR (one form of a connection target) of the smartphone SF. Will be described with an example of electrically connecting to the substrate BD.

FIG. 7 shows each example in which the contact X is attached and fixed to the substrate BD. The contact X is provided with a flat region on the outer surface side in any of the lower wall portion 11, the upper wall portion 15, and the rear wall portion 12, and these regions function as a mounting surface on the substrate BD. For example, in the lower wall portion 11, three regions (S1, S2, and S3) shown in FIG. 2 function as a mounting surface. Such a mounting surface can be bonded and fixed to the surface of the substrate BD, for example, by soldering or the like, and can be electrically connected to a circuit pattern or the like on the substrate BD side.

FIG. 7A shows an example in which the lower wall portion 11 is connected and fixed to the substrate BD, FIG. 7B shows an example in which the upper wall portion 15 is connected and fixed to the substrate BD, and FIG. In addition, examples in which the rear wall portion 12 is connected and fixed to the substrate BD are shown. Thus, the contact X can be attached to the substrate BD in various forms depending on the situation, and is a highly versatile component.

8 is a schematic configuration diagram of the smartphone SF on which the contact X is mounted, and FIG. 9 is a cross-sectional view taken along the line CC ′ shown in FIG. In FIG. 8, for simplification, the components other than the frame FR, the substrate BD, and the contact X are not shown.

The contact X is mounted (attached and fixed) so that the protruding portion 3 protrudes outside the edge in the short direction of the substrate BD in the vicinity of both ends in the short direction on the surface of the substrate BD (upper surface in FIG. 9). ing. In addition, the frame FR forms a side wall over the entire circumference of the smartphone SF, and the substrate BD is fitted inside the frame FR. By fitting the substrate BD in this way, the protrusion 3 of the contact X can be connected to the frame FR.

The protruding portion 3 is pressed against the inner wall of the frame FR. Due to the action of the leaf spring portion 2, an appropriate contact force is generated between the protruding portion 3 and the inner wall of the frame FR, and a stable contact between them is obtained. The frame FR can function as an antenna, for example. In this case, the circuit on the substrate BD is electrically connected to the antenna by the action of the contact X.

Further, in a form in which a circuit on the substrate BD is electrically connected to the frame FR using the contact X (hereinafter referred to as “this embodiment”), a region indicated by a broken line in FIG. 9 (the lower side of the substrate BD). It is also possible to secure a space. Therefore, in this embodiment, circuit components and the like can be more sufficiently arranged on the lower surface of the substrate BD. For example, compared to the form shown in FIGS. 16 and 17 (hereinafter referred to as “comparative example”), the substrate BD is provided. This is advantageous in terms of component mounting.

Here, the above comparative example will be described. 16 is a schematic configuration diagram of a smartphone according to a comparative example, and FIG. 17 is a cross-sectional view taken along the line DD ′ shown in FIG. In the comparative example, the substrate BDx (corresponding to the substrate BD in this embodiment) and the frame FRx (corresponding to the frame FR in this embodiment) are connected using a metallic screw SC. Also in the comparative example, the board BDx can be electrically connected to the frame FRx, but a screw hole is required in the board BDx, and a circuit component is shown in a region (in the vicinity of the hole) indicated by a broken line in FIG. Etc. cannot be placed. That is, in the comparative example, such a dead space is generated in the board BDx, but in this embodiment, such a dead space is not generated, which is advantageous in terms of component mounting on the board BD.

Also, in the comparative example, it is necessary to form a screw hole tap hole in the frame FRx. On the other hand, in the present embodiment, such a tapped hole is unnecessary, so that the production cost of the frame FR can be reduced accordingly. Further, in the comparative example, the procurement cost of the screw SC, the work cost of screwing, and the corresponding cost for preventing the connection failure due to the looseness of the screw SC are required. In this embodiment, such a cost is unnecessary, and basically, the substrate BD on which the contact X is mounted may be fitted into the frame FR, so that the manufacturing cost and quality control cost of the smartphone SF are suppressed. It is possible.

As shown in FIG. 10, it is also possible to mount the contact X on the back surface of the substrate BD (the lower surface in FIG. 10) and to electrically connect the substrate BD to the frame FR. In this case, a sufficient space can be secured on the surface of the substrate BD, which is very advantageous in terms of component mounting on the upper surface of the substrate BD.

Next, the process of fitting the board BD on which the contact X is mounted into the frame FR will be described with reference to FIG. As shown in FIG. 11, the upper inner side of the frame FR is chamfered to form an inclined surface FR1. The inclined surface FR1 is formed to have an inclination of about 45 ° with respect to a plane parallel to the surface of the substrate BD.

FIGS. 11A-1 to 11A-3 show the state of the process of fitting the substrate BD on which the contact X is mounted on the upper surface into the frame FR. In this step, the frame FR is connected to the contact X in a side approach mode. In the situation before the fitting shown in FIG. 11 (A-1), the protruding portion 3 has not yet been pushed by the frame FR, and is in the initial state in which the protruding portion 3 protrudes most. Further, the lower guide wall portion 32D is positioned in the vicinity of the uppermost portion of the inclined surface FR1.

When the board BD is moved from this state and the fitting into the frame FR is advanced, the lower guide wall portion 32D is slid on the inclined surface FR1, as shown in FIG. The protrusion 3 is retracted by receiving a backward force from the inclined surface FR1. In this situation, since the portion of the lower guide wall portion 32D that contacts the inclined surface FR1 is curved, the lower guide wall portion 32D can slide smoothly on the inclined surface FR1, and the inclined surface FR1 can be prevented from being damaged. . Finally, as shown in FIG. 11 (A-3), the substrate BD is pushed into the frame FR to be completely fitted, and the tip contact portion 31 comes into contact with the inner wall FR2 of the frame FR.

FIGS. 11B-1 to 11B-3 show the state of the process of fitting the substrate BD having the contact X mounted on the lower surface into the frame FR. Also in this step, the frame FR is connected to the contact X in a side approach mode. In the state before the fitting shown in FIG. 11 (B-1), the projecting portion 3 is not yet pushed by the frame FR, and the projecting portion 3 is in the initial state in which it projects most. Further, the upper guide wall portion 32U is located in the vicinity of the uppermost portion of the inclined surface FR1.

When the board BD is moved from this state and the fitting into the frame FR is advanced, as shown in FIG. 11 (B-2), the upper guide wall 32U slides on the inclined surface FR1, The protrusion 3 is retracted by receiving a backward force from the inclined surface FR1. In this situation, since the portion of the upper guide wall portion 32U that contacts the inclined surface FR1 is curved, the upper guide wall portion 32U can smoothly slide on the inclined surface FR1, and the inclined surface FR1 can be prevented from being damaged. . Finally, as shown in FIG. 11 (B-3), the substrate BD is pushed into the frame FR to be completely fitted, and the tip contact portion 31 contacts the inner wall FR2 of the frame FR.

As described above, since the lower guide wall portion 32D and the upper guide wall portion 32U are curved and rounded, the contact X is inclined from the side of the protruding portion 3 (the direction orthogonal to the protruding direction of the protruding portion 3). The protrusion 3 can be appropriately retracted by being pushed by the FR1. The contact X has a left side wall portion 32L and a right side wall portion 32R that form a series of inverted U-shaped contact portions with the tip contact portion 31, so that the lower guide wall portion 32D and the upper guide wall portion 32U described above A similar function can be exhibited. That is, the contact X can appropriately retract the protruding portion 3 such that the left side wall portion 32L and the right side wall portion 32R are pushed by the inclined surface FR1 from the left side or the right side.

Further, in the contact X, each side wall portion and the guide wall portion of the projecting portion 3 are curved, so that the contact target is not limited to the case where the projecting portion 3 is pushed by the inclined surface as described above. The protrusion 3 can be appropriately retracted even when it is pushed. Therefore, the contact X is a highly versatile part that can be used for various connection objects. This point will be specifically described with reference to the example of FIG.

FIG. 12 shows a state of a process in which a rectangular parallelepiped connection target Ob is brought close to the substrate BD on which the contact X is mounted in various forms, and the connection target Ob is electrically connected to the substrate BD.

FIG. 12A shows a state in which the connection object Ob is brought into contact with the protruding portion 3 from the lower side of the contact X. FIG. In this case, first, a corner portion of the connection object Ob (portion surrounded by a dotted line in the drawing) contacts the lower guide wall portion 32D. However, since the lower guide wall portion 32D is curved, the corner portion is not caught by the lower guide wall portion 32D, and the connection object Ob can advance while smoothly pushing the protruding portion 3 away.

That is, the lower guide wall portion 32D extends from the lower side of the tip contact portion 31 narrower than the plate width of the left and right

side wall portions

32L and 32R as shown in FIG. The lower curved guide portion 32D-1 is formed by being bent along the locus of the arc-shaped lower guide surface 31-2. As apparent from FIG. 2, the lower curved guide portion 32 D is made by an amount corresponding to the interval between the lower side of the tip contact portion 31 and the lower wall portion 11 being larger than the interval between the lower wall portion 11 and the side surfaces of the side wall portions 32 L and 32 R. Many -1 curved dimensions can be taken.

For this reason, the arc-shaped portion formed by the lower guide surface 31-2 and the lower curved guide portion 32D-1 of the tip contact portion 31 is more external than the lower arc-shaped portions of the

side wall portions

32L and 32R whose cross sections are formed in an arc shape. (See FIG. 2).
Therefore, even if the corner portion of the connection object Ob is in a positional relationship where it abuts against the side surface portions of the

side wall portions

32L and 32R, the corner portion is first positioned on the lower side (outside) of the side surface portion. Therefore, it moves to the lower guide surface 31-2 along the curved surface and smoothly contacts the tip portion of the tip contact portion 31.

That is, the contact external force at the corner applied to the lower curved guide portion 32D-1 is decomposed into a tangential direction and a normal direction of the lower curved guide portion 32D-1. The component in the normal direction can be divided into a force for pushing the protrusion 3 and a force positioned in the width direction. Among these, the force that is positioned in the width direction is absorbed and relaxed by the action of the upper guide wall portion 32U described later, so that the projection portion is not greatly displaced in the width direction, and the force that pushes in the contact portion 3 As a result, the contact portion 3 is retracted into the housing 1. As a result, the connection object Ob is positioned at the apex portion of the tip contact portion 31 and can be stably contact-connected by the elastic force of the spring portion 2. In this respect, it is greatly different from the conventional protrusion-biased contact.

When the corner portion comes into contact with the lower curved guide portion 32D-1, a force for pushing up the protruding portion 3 (a force for displacing in the width direction) is applied. In this case, the upper guide wall portion 32U has the upper convex portion 41U elastically pressed against the inner surface of the upper wall portion 15 as shown in FIG. 4, so that the elastic force of the upper guide wall portion 32U causes the protrusion 3 to Absorbs and relaxes the upward displacement, and prevents deformation of the protrusion 3, the left and

right side walls

32L, 32R, and the like. If the upper guide wall portion 32U is not elastically pressed against the inner surface of the upper wall portion 15, the contact portion 3 and the like are positioned and deformed by the upward force applied to the protruding portion 3.
In other words, the upper and lower

guide wall portions

32U and 32D play a role of smoothly guiding the connection object Ob to the tip contact portion 31 and a role of a buffer against an external force applied to the tip contact portion 31. In addition, the role of the conductive path can be given.

FIG. 12B shows a state in which the connection object Ob is brought into contact with the protrusion 3 from the upper side of the contact X. In this case, first, a corner portion of the connection object Ob (portion surrounded by a dotted line in the drawing) contacts the upper guide wall portion 32U. However, since the upper guide wall portion 32U is curved, the corner portion is not caught by the upper guide wall portion 32U, and the connection object Ob can advance while smoothly pushing the protruding portion 3 away.
In the above case, the upper guide wall 32U plays the same role as the lower guide wall 32D, but the description thereof is omitted.

FIG. 12C shows a state in which the connection object Ob is brought into contact with the protruding portion 3 from the right side of the contact X. In this case, first, the corner portion of the connection object Ob (the portion surrounded by the dotted line in the figure) contacts the right side wall portion 32R. However, since the right side wall portion 32R is curved, the corner portion is not caught by the right side wall portion 32R, and the connection object Ob can advance while smoothly pushing away the protruding portion 3.

FIG. 12 (D) shows a state in which the connection object Ob is brought into contact with the protruding portion 3 from the left side of the contact X. In this case, first, a corner portion of the connection object Ob (portion surrounded by a dotted line in the drawing) contacts the left side wall portion 32L. However, since the left side wall portion 32L is curved, the corner portion is not caught by the left side wall portion 32L, and the connection object Ob can proceed while pushing the protruding portion 3 smoothly.

As described above, the connection object Ob does not get caught by the protrusion 3 even if the connection object Ob approaches the protrusion 3 from any one of the lateral directions (up, down, left, and right) of the protrusion 3. You can proceed to push away smoothly. Finally, the tip contact portion 31 of the protrusion 3 can be brought into contact with the connection object Ob. As shown in FIG. 12E, the tip contact portion 31 of the protrusion 3 can be brought into contact with the connection object Ob even when the connection object Ob is made to approach the protrusion 3 from the front.

[Opening prevention hook mechanism]
As described above, the hole 13a1 is provided in the front front wall portion 13a, and the claw portion 13b1 is provided in the rear front wall portion 13b (see FIG. 1 and the like). Further, in the front wall portion 13, the claw portion 13b1 is located in the hole portion 13a1, and the upper edge of the claw portion 13b1 is opposed to and in contact with the upper edge of the hole portion 13a1. The claw portion 13b1 functions as a hook mechanism for preventing the housing portion 1 from being opened (failure due to deformation) due to external force. This point will be described in detail with reference to FIG.

FIG. 13 is a perspective view showing a situation in which the frame FR approaches the protrusion 3 from below (the same situation as in FIGS. 11A-1 to 11A-3). When the frame FR moves upward as indicated by a dotted arrow in FIG. 13, the protrusion 3 receives an upward force from the frame FR while moving backward. Due to this force, as indicated by the colored arrows in FIG. 13, the upper wall portion 15 receives an upward force (a force in the direction in which the housing portion 1 opens).

However, even in such a situation, in this embodiment, when the claw portion 13b1 is caught in the hole 13a1, the vertical displacement between the front front wall portion 13a and the rear front wall portion 13b (the upper wall portion 15 and the lower wall portion 15b1) The positional deviation in the direction in which the wall portion 11 is separated is suppressed, and the opening of the housing portion 1 (problems due to deformation) is prevented. Thus, the front side front wall part 13a and the rear side front wall part 13b have projections provided on one side (the claw part 13b1 provided on the rear side front wall part 13b) on the other side so that the vertical displacement is suppressed. It is formed so as to be hooked on the (front-side front wall portion 13a). Such protrusions may be provided on either the front front wall portion 13a or the rear front wall portion 13b.

The housing part 1 has a front wall part 13 so as to cover the plate spring part 2 from the front and rear and the upper and lower sides, a predetermined part of the metal plate material (front side front wall part 13a, lower wall part 11, rear wall part 12, upper wall part. 15 and a portion where the rear front wall portion 13b is connected in order) are bent so as to form a cylindrical shape. Further, the front wall portion 13 is formed by overlapping a front front wall portion 13a on one end side of the predetermined portion and a rear front wall portion 13b on the other end side of the predetermined portion. Furthermore, the front side front wall part 13a and the rear side front wall part 13b are formed such that a protrusion (claw part 13b1) provided on one side is hooked on the other side so that vertical displacement is suppressed. Therefore, it is possible to prevent the opening of the housing part 1 due to an external force as much as possible.

[Roles of the guide section]
As described above, the contact X is provided with the upper guide wall portion 32U having the upper convex portion 41U that contacts the inner wall of the housing portion 1, the lower convex portion 41D, and the lower guide wall portion 32D. A pair of an upper guide portion 42U and a lower guide portion 42D are provided apart from each other in the left direction (see FIGS. 4 to 6). These convex portions and guides play a role of suppressing displacement of the leaf spring portion 2 and the protruding portion 3 (movement that rotates in the vertical direction).

More specifically, when the projecting portion 3 is pushed back by the connection target or the like, the upper convex portion 41U and the upper guide portion 42U of the upper guide wall portion 32U slide inside the upper wall portion 15 and move downward. The lower convex portion 41D and the lower guide portion 42D of the guide wall portion 32D slide inside the lower wall portion 11. The inner side of the upper wall part 15 and the inner side of the lower wall part 11 correspond to the inner wall of the housing part 1. Therefore, for example, as shown in FIG. 13, even when the protrusion 3 moves backward while receiving upward force from the frame FR, each guide wall (32U, 32D) and each guide (42U, 42D) By being in contact with the inner wall of the housing part 1, the displacement of the leaf spring part 2 and the protruding part 3 is suppressed.

Even when the protruding portion 3 is retracted while receiving a downward force from the frame FR or the like, the displacement of the leaf spring portion 2 and the protruding portion 3 is suppressed by the same principle. By suppressing the displacement in this way, it is possible to stabilize the operation of the contact X and to suppress the quality deterioration of the contact X.

Further, when the upper and lower convex portions (41U, 41D) are in contact with the housing portion 1, it is possible to shorten the electrical length between the connection target in contact with the protruding portion 3 and the connection target in contact with the housing portion 1. It has become. This will be described below with reference to FIG.

14A shows a state where the lower wall portion 11 is fixed to the substrate BD, FIG. 14B shows a state where the upper wall portion 15 is fixed to the substrate BD, and FIG. 14C shows the rear wall portion 12. Is fixed to the substrate BD. In addition, a thick line in FIG. 14 indicates a current path from the protruding portion 3 where the contact of the connection target is planned to the substrate BD.

As shown in this figure, the contact X passes through the upper guide wall portion 32U or the lower guide wall portion 32D regardless of which of the lower wall portion 11, the upper wall portion 15, and the rear wall portion 12 is fixed to the substrate BD. As a result, the current path is very short. For example, in the state in which the rear wall 12 is fixed to the substrate BD, the current path is sufficiently shorter in the present embodiment than in the case where the current path passes through the leaf spring part 2 as shown by a thick line in FIG. 14 (c)). Thus, when the current path is shortened (in other words, a short circuit path is formed), it is easy to suppress the electrical resistance correspondingly, and it is advantageous in transmission of a high-frequency signal.

As shown in FIGS. 1, 2, and 4, when the protruding portion 3 is pushed from the front, the lower convex portion 41 D of the lower guide wall portion 32 D in the lower wall portion 11 slides upward. A shallow recess 11a is provided. Therefore, the lower convex portion 41D of the lower guide wall portion 32D can be more reliably brought into contact with the lower wall portion 11 and both electrical contacts can be stabilized. Furthermore, when the protrusion 3 is pushed from the front, a shallow recess 15a is provided at a location where the upper convex portion 41U of the upper guide wall portion 32U slides in the upper wall portion 15. Therefore, it is possible to more reliably bring the upper convex portion 41U of the upper one guide wall portion 32U into contact with the upper wall portion 15 and stabilize both electrical contacts.

These depressions (11a, 15a) face each other so as to substantially overlap in the vertical direction, and the interval between the inner walls in the vertical direction of the housing part 1 is narrowed. This interval is slightly smaller than the distance between the tips of the

convex portions

41D and 41U (the distance in the vertical direction). Moreover, these hollows (11a, 15a) can be formed by a simple press work or the like on a plate material.

As shown in FIG. 4, in the vicinity of the initial state in which the protruding portion 3 is hardly pressed from the front, the

convex portions

41D and 41U are located in front of the recesses (11a, 15a). In this state, the tip of each convex portion is only lightly pressed against the inner wall of the housing portion 1. And if the protrusion part 3 is pushed predetermined amount from the front, these convex parts will rush into the position pinched | interposed into each hollow (11a, 15a). In this state, using the elastic force of each guide wall part (32U, 32D), the tip of each

convex part

41D, 41U generates a predetermined contact force with the inner wall of the housing part 1, and is crimped to the inner wall. is doing.

Assuming that the

protrusions

41D and 41U are located between the depressions (11a and 15a) even in the vicinity of the initial state, for example, after the protrusion 3 is pressed backward and moved sufficiently. When the pressure is released, the elastic force of the leaf spring portion 2 is zero or very weak in the vicinity of the initial state, so that the protruding portion 3 returns to the initial state due to friction between the convex portions and the depressions (11a, 15a). There is no fear. In this respect, in the present embodiment, the friction is hardly generated in the vicinity of the initial state, so that the protruding portion 3 can be more reliably returned to the initial state. In the vicinity of the initial state of this embodiment, the contact between the upper and lower convex portions (41U, 41D) and the inner wall of the housing portion 1 is light, but the presence of the respective

guide wall portions

32U, 32D. In addition, the restoring force that suppresses the positioning of the protrusions 3 and the like and restores the original state is applied. Since the upper and lower guide portions (42U, 42D) are in contact with the inner wall of the housing portion 1, the displacement of the leaf spring portion 2 and the protruding portion 3 is promoted.

[Shock resistance]
The contact X is devised in the structure of the housing part 1 and has excellent characteristics in impact resistance. As described above, the lower edge of the front upper right wall portion 14aU and the upper edge of the front lower right wall portion 14aD are vertically opposed to each other with a slight gap, and the rear upper right wall portion 14bU The lower edge and the upper edge of the rear lower right wall 14bD are opposed to each other in the vertical direction with a slight gap. Therefore, for example, even when a foreign object collides with the upper wall portion 15 from above, each right wall portion (14aU, 14aD, 14bU, 14bD) functions to receive the force and prevent the housing portion 1 from being crushed. .

Further, as shown in FIG. 15, if a part β of the lower side edge of the rear front wall part 13b is placed in contact with or close to a part α of the front side edge of the lower wall part 11, the upper side is viewed from above. The rear front wall portion 13b receives an impact applied to the wall portion 15, and the housing portion 1 can be more sufficiently prevented from being crushed as described above. Further, since the front wall portion 13 has a double structure of the front side front wall portion 13a and the rear side front wall portion 13b, even if a foreign object collides with the front wall portion 13 from the front, for example, the front wall portion 13 is difficult to bend.

[Other configuration examples of the right wall]
FIG. 19 is a configuration diagram relating to another configuration example of the right wall portion 14 in the contact X. The lower diagram in FIG. 19 is an enlarged view of the vicinity of the front right wall portion RW1. Here, for easy understanding of the configuration, the front half of the front right wall portion RW1 is cut off and displayed. Yes. The right wall portion 14 shown in FIG. 19 includes a front right side wall portion 14cU instead of the front upper right wall portion 14aU shown in FIG. 1 and the like, and a front left side right wall portion 14cD instead of the front lower side right wall portion 14aD. A rear right wall 14dU is provided instead of the rear upper right wall 14bU, and a rear left right wall 14dD is provided instead of the rear lower right wall 14bD. The front right wall 14cU and the rear right wall 14dU are connected to the upper wall 15, and the front left wall 14cD and the rear right wall 14dD are connected to the lower wall 11. Yes.

The front right wall portion 14cU and the front left right wall portion 14cD overlap the left and right to form the front right wall portion RW1. The front right wall 14cU is in close contact with the right side of the front left wall 14cD. Further, the rear right side wall part 14dU and the rear left side right wall part 14dD overlap with each other to form a rear right wall part RW2. The rear right side wall portion 14dU is in close contact with the right side of the rear left side right wall portion 14dD.

In the front right wall RW1, the front right wall 14cU is formed with a cut piece 14cU1 that is cut and bent leftward, and the front left right wall 14cD is cut leftward. A cut and bent piece 14cD1 is formed. These cut and bent pieces 14cU1 and 14cD1 (the pieces formed by bending the upper portion around the axis extending in the front-rear direction provided on the lower side so that the upper portion is slightly rotated leftward) are formed at positions substantially overlapping in the left-right direction. Has been. Thereby, the upper end portion of the cut and bent piece 14cU1 protruding leftward from the front right side wall portion 14cU and the recess formed in the front left side right wall portion 14cD (the recess formed by bending the cut and bent piece 14cD1). The upper edge faces in the up-down direction (see the position H shown in FIG. 19).

In this way, in the front right wall RW1, the front right wall 14cU and the front left right wall 14dU are prevented from being displaced in the direction in which the upper wall 15 and the lower wall 11 are separated. The cut and bent piece 14cU1 is formed so as to be hooked on the front left side right wall portion 14dU (so that the protrusion provided on one side is hooked on the other side). Therefore, it is possible to prevent as much as possible the opening of the housing part 1 due to external force (defect caused by deformation). Such a configuration is also provided in the rear right wall portion RW2, and here, the same effect as that of the front right wall portion RW1 can be obtained.

[Others]
As described above, the contact X according to the present embodiment includes the retractable protruding portion 3 formed to protrude forward using a conductive plate material, and the leaf spring portion that biases the protruding portion 3 forward. 2 and electrically connecting the connection target that has contacted the tip contact portion 31 of the protrusion 3 to the connection target. In addition, the protruding portion 3 has a plurality of guide wall portions (32U, 32D) and left and right wall portions (32L, 32R), whose plate surfaces are exposed in the four lateral directions, respectively, branching from the vicinity of the tip contact portion 31, respectively. It extends to the side.

Therefore, the contact X is a protruding portion biasing type, and the side wall of the protruding portion covers many side directions (in this embodiment, four directions, up, down, left and right). It is advantageous.

That is, each guide wall portion and each side wall portion (32U, 32D, 32L, 32R) are each formed by branching from the vicinity of the tip contact portion 31 and extending rearward, and thus are easily formed by bending a conductive plate material. Is possible. Further, even when the whole or a part of each guide wall part and each side wall part (32U, 32D, 32L, 32R) is formed by a method according to drawing, the respective side wall parts are separated. As compared with the case where the drawing process is performed so as to provide a dome-shaped depression on the flat plate, problems such as a reduction in plate thickness hardly occur. For example, in the case of the present embodiment, in order to make the tip contact portion 31 rounded, each guide wall portion, each sidewall portion ( 32U, 32D, 32L, and 32R) can be formed by bending. Therefore, in this embodiment, drawing with relatively high accuracy is not required, and the degree of freedom of material selection is hardly limited to employ a metal plate material suitable for drawing.

In the present embodiment, the guide wall and the side wall are efficiently provided so as to cover only the necessary four directions, compared to the case where the side wall is provided so as to cover all lateral directions (the projecting portion is formed in a dome shape). Since it is provided, the amount of guide walls and side walls is reduced accordingly, which is advantageous in terms of weight reduction. Furthermore, in this embodiment, since each guide wall part and each side wall part (32U, 32D, 32L, 32R) are each branched and extended from the front-end | tip contact part 31, the guide wall part and each side wall part are independent. It is easy to adjust the shape. In the present embodiment, the plurality of side wall portions are exposed in each of the four lateral directions. However, the plurality of side wall portions may be exposed in each of three or five or more side directions. .

In the developed view of the tip contact portion 31 shown in FIG. 20, a T-shape without the right side wall portion 32R can be used as a front approach mode or a side approach mode. Similarly, in the T-shape, only one of the upper and lower

guide wall portions

32U and 32D may be a curved guide portion. In this case, the contact object is used in the form of approaching sideways from the direction in which only the curved guide portion is provided.

Further, each guide wall portion and each side wall portion (32U, 32D, 32L, 32R) extend rearward while bulging outward in the lateral direction from the vicinity of the tip contact portion 31. That is, the positions of the guide wall portions and the side wall portions (32U, 32D, 32L, 32R) gradually approach inward in the lateral direction as proceeding to the front side. Therefore, as described with reference to FIG. 12, it is possible to prevent the connection target from being caught on each side wall portion in the side approach mode, and to smoothly guide the connection target to the front contact portion 31. Particularly in the present embodiment, the surfaces of the guide wall portions, the side wall portions (32U, 32D, 32L, 32R), and the tip contact portion 31 are formed as a series of curved surfaces that are convex to the front side. It is possible to guide the connection target in front of the tip contact portion 31 very smoothly in the approach mode.

Further, the contact X according to the present embodiment is a contact formed by bending a single conductive plate, and the housing part 1 having the front wall part 13, the rear wall part 12, the upper wall part 15, and the lower wall part 11. And an arc-shaped projecting portion 3 that protrudes from the opening of the front wall portion 13 and is convex to the front side when viewed in the vertical direction in contact with the contact object (connection object); and A plate spring that forms at least a part of a conductive path from the projecting portion 3 and has at least one bent portion that is connected to the projecting portion 3 on the free end side and biases the projecting portion 3 toward the contact object. Part 2. Further, the protruding portion 3 extends upward and backward while the upper and lower guide wall portions (upper guide wall portion 32U and lower guide wall portion 32D) branch in the upper and lower side directions and bulge outward in the lateral direction. Further, the free end portions of the upper and lower guide wall portions elastically slidably contact the inner surfaces of the upper wall portion 15 and the lower wall portion 11 of the housing portion 1 to form a short-circuit conductive path.

With this configuration, the contact X is a protruding portion energizing type and can be connected in the side approach mode in each of the upper, lower, left, and right side directions, but the connection target is not easily caught on each side wall in the side approach mode. In addition, it is possible to stably form a conductive path that shortens the electrical length. Moreover, in this embodiment, the surface of the protrusion part 3 and each surface of the said side wall piece part are formed as a series of curved surfaces which are convex to the front side. Therefore, in the side approach mode, the connection target can be guided very smoothly to the front end portion of the protruding portion 3.

The contact X described above is a contact formed by bending a single conductive plate, and is housed in the housing, a projecting portion that projects from the opening of the housing and contacts a connection target, A member that forms at least a part of a conductive path from the protruding portion, and a free end side of which is connected to the protruding portion, and a spring portion that biases the protruding portion in the protruding direction. The projecting portion branches in the width direction of each guide side wall and bulges outward in the width direction while extending outward in the direction opposite to the projecting direction, and at least one of the guide side wall portions has a free end at the housing. It is the structure which is slidably elastically contacting the wall part inner surface.

According to the present configuration, since it is a folding-type protruding portion biasing type contact formed by bending a conductive plate material, it is possible to connect in the lateral approach mode in the width direction of the protruding portion. The versatility is greatly improved. Even if other parts accidentally hit the side of the protruding portion, they are protected by the guide side wall portion, so that the contact can be resistant to deformation and damage.

Furthermore, since at least one of the guide side wall portions is elastically slidably in contact with the inner wall surface of the housing, the guide side wall portion can be used as a conductive path having a short electrical length.

More specifically, as the above configuration, the surface of the protruding portion and the surface of each of the guide side wall portions may be formed as a series of curved surfaces that are convex to the front side. According to this configuration, in the lateral approach mode, the connection target can be guided very smoothly to the front end portion of the protruding portion.

More specifically, as the above configuration, one end of the protruding portion may be connected to the leaf spring portion. According to this structure, it becomes possible to form a protrusion part and a leaf | plate spring part efficiently with a series of metal plate materials.

More specifically, in the above configuration, the protruding direction is the front, and the front wall portion, the rear wall portion, the upper wall portion, and the lower wall portion of the housing have a predetermined portion of the conductive plate material in a cylindrical shape. The front wall portion is formed by bending a front front wall portion on one end side of the predetermined portion and a rear front wall portion on the other end side of the predetermined portion. Formed so that the front front wall portion and the rear front wall portion have protrusions provided on one side on the other side so that displacement in the direction in which the upper wall portion and the lower wall portion are separated is suppressed. It is good also as a structure formed so that it might be hooked. According to this configuration, it is possible to prevent the opening of the housing portion due to an external force (a malfunction due to deformation) as much as possible.

More specifically, the housing has a specific wall portion that is a left or right wall, and the specific wall portion is a first specific wall portion that is connected to an upper wall portion of the conductive plate. And a second specific wall portion connected to the lower wall portion of the conductive plate is formed to overlap the left and right, and the first specific wall portion and the second specific wall portion are the upper wall portion and the lower wall. It is good also as a structure formed so that the protrusion provided in one might be caught in the other so that the position shift to the direction which a part leaves | separates may be suppressed. According to this configuration, it is possible to prevent the opening of the housing portion due to an external force (a malfunction due to deformation) as much as possible.

2. Second Embodiment Next, a second embodiment will be described. In the following description, emphasis is placed on the description of matters that are different from the first embodiment, and descriptions of matters that are common to the first embodiment may be omitted. In addition, elements having the same meaning as in the first embodiment may be described with the same reference numerals.

FIGS. 21 and 22 are external perspective views of the contact Y according to the second embodiment viewed from different directions, respectively, and FIG. 23 is a cross-sectional view from the lower viewpoint when the contact Y is cut at the center surface in the vertical direction. It is. FIG. 24 shows a cross-sectional view of the contact Y taken along the line AA ′ shown in FIG.

The contact Y differs from the contact X according to the first embodiment in terms of specific shapes, dimensions, and the like as shown in the above drawings, but the overall configuration is generally equivalent. Yes. The housing 1 in the contact Y has a horizontal dimension of about 7.5 mm, a vertical dimension of about 3 mm, and a longitudinal dimension of about 3.8 mm. In the initial state, the forward protrusion amount of the protrusion 3 is about 2.1 mm, and the front-rear direction dimension of the contact Y at this time is about 5.9 mm.

Further, in the contact Y, as shown in FIG. 23, the rear rectilinear portion 22 of the leaf spring portion 2 extends obliquely left frontward from the lower turn portion 21 toward the upper turn 23. The contact Y is suitably used for various on-vehicle electronic devices such as car audio and car navigation systems, and can be used for various applications that require electrical connection.

The right wall portion 14 of the contact Y is constituted by a right side right wall portion 14a and a left side right wall portion 14b. The right side right wall part 14 a is connected to the front end position of the right end of the upper wall part 15, and the left side right wall part 14 b is connected to the front end position of the right end of the lower wall part 11. The right side wall part 14a and the left side right wall part 14b overlap the left and right to form the right wall part 14. The right side right wall part 14a is in close contact with the right side of the left side right wall part 14b.

A cut and bent piece 14a1 formed by cutting and bending to the left is formed on the right right wall portion 14a, and a cut and bent piece 14b1 formed by cutting and bending to the left is formed on the left right wall portion 14b. Has been. These cut and bent pieces 14a1 and 14b1 (pieces formed by bending the upper portion slightly to the left around the axis extending in the front-rear direction provided on the lower side) are formed at positions almost overlapping in the left-right direction. Has been. As a result, the upper end portion of the cut and bent piece 14a1 protruding leftward from the right right wall portion 14a and the upper portion of the recess formed in the left right wall portion 14b (the recess formed by bending the cut and bent piece 14b1). The edge is opposed to the vertical direction.

In this way, in the right wall portion 14, the right right wall portion 14a and the left right wall portion 14b are cut and bent so that the positional deviation in the direction in which the upper wall portion 15 and the lower wall portion 11 are separated is suppressed. 14a1 is formed so as to be hooked on the left-side right wall portion 14b (so that a protrusion provided on one side is hooked on the other side). Therefore, it is possible to prevent as much as possible the opening of the housing part 1 due to external force (defect caused by deformation).

Further, as shown in FIG. 24, when the protruding portion 3 is pushed from the front, a part of the lower wall portion 11 is located at a position where the lower convex portion 41D of the lower guide wall portion 32D slides in the lower wall portion 11. A lower wall inclined portion 11x formed by cutting and bending is provided. Further, when the protruding portion 3 is pushed from the front, a part of the upper wall portion 15 is cut and bent at a location where the upper convex portion 41U of the upper guide wall portion 32U slides in the upper wall portion 15. An upper wall inclined portion 15x is provided. These inclined portions (11x, 15x) are inclined so as to go inward of the housing portion 1 as they move backward (in the direction opposite to the protruding direction of the protruding portion 3), and the inclined portions (11x, 15x) The distance D1 between the rear ends is smaller than the dimension D2 in the width direction (vertical direction) of the housing part 1 where no inclination is provided.

The lower wall inclined portion 11x is provided with a cut in a rectangular shape (excluding the front side extending left and right) in the lower wall portion 11 having a longer side extending in the front-rear direction than the side extending in the left and right direction. It is a piece-like part formed by bending the rear part so as to rotate slightly upward as an axis. The lower wall inclined portion 11x extends from the front side (base side) to the rear side by being inclined upward by an amount corresponding to the rotation angle, and is inclined so as to go to the inner side of the housing portion 1 as it goes rearward. As the lower guide wall portion 32D mainly functions as a leaf spring, the lower convex portion 41D elastically slides on the lower wall inclined portion 11x. Further, the lower guide wall portion 32D is more elastically deformed as the protruding portion 3 is retracted due to the inclination of the lower wall inclined portion 11x, and the elastic force of the lower guide wall portion 32D is increased. A stronger contact is made with the wall inclined portion 11x.

The upper wall inclined portion 15x is provided with a cut in a rectangular shape (excluding the front side extending left and right) in the upper wall portion 15 having a longer side extending in front and rear than the side extending left and right. It is a piece-like part formed by bending the rear part as a shaft so as to rotate slightly downward. The upper wall inclined portion 15x extends from the front side (base side) to the rear side so as to incline downward by an amount corresponding to the rotation angle, and inclines toward the inner side of the housing portion 1 as it goes rearward. Mainly the upper guide wall portion 32U functions as a leaf spring, so that the upper convex portion 41U elastically slides on the upper wall inclined portion 15x. Further, the upper guide wall portion 32U is more elastically deformed as the projecting portion 3 is retracted due to the inclination of the upper wall inclined portion 15x, and the elastic force of the upper guide wall portion 32U is increased. A stronger contact is made with the inclined portion 15x.

As described above, the lower convex portion 41D is elastically slidably in contact with the lower wall inclined portion 11x, and the upper convex portion 41U is elastically slidably in contact with the upper wall inclined portion 15x, whereby the convex portions (41D, 41U) in the respective portions. And the inclined portions (11x, 15x) can be made more reliable, and the electrical contact can be made more stable. Furthermore, the working area (appropriate operating range) of the contact Y can be widened by inclining the inclined portions (11x, 15x) as described above. This point will be described in more detail with reference to FIG.

The graph shown in FIG. 25 shows the contact force P (corresponding to the contact force between the connection target and the tip contact portion 31) and the contact resistance Q (connection) when the protrusion 3 is moved using the contact Y sample. The result of measuring (corresponding to the contact resistance between the target and the connected target) is shown. In the graph, the horizontal axis indicates the distance from the rear wall portion 12 of the tip contact portion 31 (in other words, the longitudinal dimension of the contact Y at each time point), and the vertical axis indicates the contact force P and the contact resistance Q. ing.

When measuring the contact force P, the rear wall 12 of the contact Y is fixed, and a pusher (test jig) movable in the front-rear direction is installed on the front side of the tip contact part 31, and the pusher is moved in the front-rear direction. It was made to move and the front-end | tip contact part 31 was pushed. Further, the force received by the pusher from the tip contact portion 31 can be measured using a load cell (load measuring machine), and the result of this measurement is regarded as the contact force P.

The graph P1 shown in FIG. 25 shows the contact force P when the pusher is moved rearward and the protrusion 3 is moved from the initial state (not retracted) to the predetermined final state (fully retracted). Show. Graph P2 shows contact force P when the pusher is moved forward and the protrusion 3 is moved from the final state to the initial state. Note that the alternate long and short dash line shown in FIG. 25 corresponds to a graph of the contact force P when it is assumed that there is no friction between the convex portions (41D, 41U) and the housing portion 1. As the position of the protruding portion 3 is closer to the initial state, the difference between the graphs P1 and P2 from the one-dot chain line shown in FIG. 25 is smaller.

Further, when measuring the contact resistance Q, a substrate fixed to the rear wall portion 12 and a substrate that is in contact with the tip contact portion 31 (movable in the front-rear direction) are provided, and are brought into contact with the tip contact portion 31. The result of measuring the resistance value between the two substrates while moving the substrate was regarded as the contact resistance Q. A graph Q shown in FIG. 25 shows the contact resistance Q when the protrusion 3 is moved from the final state to the initial state by moving the substrate. The contact resistance Q basically becomes a constant value (about 20 mΩ in this embodiment) when the contact force P exceeds a predetermined reference value (about 0.2 N in this embodiment), and the contact resistance Q is normal. The function (function to appropriately connect the connection target and the connection target) is exhibited.

In addition, the operation range where the contact resistance Q is stabilized at the certain value (the range of the protruding amount of the protruding portion 3) is a working area where the function of the contact Y is satisfactorily exhibited, and the contact Y according to the present embodiment. In this case, a region W1 shown in FIG. 25 is a working area. Here, it is assumed that the distance between the inner surfaces of the upper wall portion 15 and the lower wall portion 11 is constant at D1 (see FIG. 24) without providing the inclined portions (11x, 15x) in the contact Y. The contact force P when 3 is moved from the final state to the initial state is approximately as shown by a graph P2 'in FIG.

In this hypothetical situation, it is possible to stably contact each convex portion (41D, 41U) and the housing portion 1 using the elastic force of each guide wall portion (32D, 32U). Since the distance between the inner surfaces of the upper wall portion 15 and the lower wall portion 11 is constant even if 3 advances forward, the friction between the convex portions (41D, 41U) and the housing portion 1 hardly changes. Therefore, in the case of the graph P2 ′, the gradient of the graph is almost the same as the gradient of the alternate long and short dash line shown in FIG. 25, and the contact force P decreases faster than the graph P2.

As shown by the graph P2 ′, when the contact force P decreases relatively quickly, the contact force P falls below the reference value described earlier, and the working area becomes the region W2 shown in FIG. This working area W2 is smaller than the working area W1 of this embodiment by the amount indicated by the white arrow Wp in FIG. As is clear from the above description, in the present embodiment, by providing the inclined portions (11x, 15x), the guide wall portions (32U, 32D) are appropriately brought into contact with the housing portion 1, and a relatively wide working area is provided. It is possible to secure an area.

In addition, the difference (shift amount) between the graphs P1 and P2 shown in FIG. 25 and the one-dot chain line increases as the inclination angle of each inclined portion (11x, 15x) increases. In consideration of this point, it is desirable that the inclination angle is appropriately set according to the product specifications. In the case where the inclined portions (11x, 15x) are provided by bending a part of the housing portion 1 as in this embodiment, the angle of the inclination can be easily adjusted by changing the angle of bending in the cutting and bending. Is possible. However, each inclined portion (11x, 15x) can also be provided by other methods such as a method in which a part of the housing part 1 is recessed by pressing.

Further, as shown in FIG. 21 and FIG. 22 and the like, a lower engagement hole 11y having a shape extending in the front-rear direction is provided in the right side portion of the lower wall portion 11, and a right side portion of the upper wall portion 15 is An upper engagement hole 15y having a shape extending in the direction is provided. These engagement holes (11y, 15y) are arranged symmetrically with respect to the center surface in the vertical direction of the contact Y, and are formed in the same shape and size.

On the other hand, the contact Y is provided with a lower engaging portion 33D and an upper engaging portion 33U extending from the protruding portion 3. More specifically, the lower engagement portion 33D extends from the lower portion of the rear end of the right side wall portion 32R, and the upper engagement portion 33U extends from the upper portion of the rear end of the right side wall portion 32R. ing. The lower engagement portion 33D has a protrusion protruding downward, and this protrusion is fitted into the lower engagement hole 11y from the inside of the housing portion 1. The upper engagement portion 33U has a protrusion protruding upward, and this protrusion is fitted into the upper engagement hole 15y from the inside of the housing portion 1.

When the protrusion 3 moves in the front-rear direction, the protrusion of the lower engagement portion 33D moves in the front-rear direction inside the lower engagement hole 11y, and the protrusion of the upper engagement portion 33U moves upward. The joint hole 15y is moved in the front-rear direction. In the present embodiment, when the protrusion 3 receives a force in the rearward direction and moves backward, the protrusion of the lower engagement portion 33D does not contact the edge of the lower engagement hole 11y, and the upper engagement portion Since the 33U protrusion does not contact the edge of the upper engagement hole 15y, friction due to the contact does not occur. However, such a contact may be generated.

On the other hand, as shown in FIG. 26, in a situation where the connection object Ob moves in the direction indicated by the colored arrow and pushes the protruding portion 3, the protruding portion 3 is pushed backward and simultaneously pushed leftward. At this time, when the protrusion 3 is moved slightly to the left, the protrusion of the lower engagement portion 33D hits the left edge of the lower engagement hole 11y, and the protrusion of the upper engagement portion 33U is the upper engagement. By hitting the left edge of the hole 15y, the protrusion 3 can be prevented from being further displaced to the left. Thereby, it is possible to suppress the protrusion 3 from being greatly displaced to the left, and it is possible to suppress occurrence of buckling in the contact Y (particularly, buckling of the leaf spring portion 2).

When the protrusion 3 is slightly moved to the right, the protrusion of the lower engagement portion 33D hits the right edge of the lower engagement hole 11y and the protrusion of the upper engagement portion 33U is the upper engagement hole. By hitting the right edge of 15y, it is possible to suppress the protrusion 3 from being further displaced to the right. In this case as well, the occurrence of buckling or the like in the contact Y can be suppressed.

In addition, since the protrusion part 3 is supported by the leaf | plate spring part 2 of the shape shown in FIG. 23 etc., the locus | trajectory of protrusion of each engaging part (33D, 33U) when the protrusion part 3 is pushed back and retracted. Is an arc-shaped trajectory that advances so as to incline slightly to the left from the true rear direction, as indicated by a broken line arrow in FIG. In consideration of this point, the shape of each engagement hole (11y, 15y) (particularly the shape of the left edge) is formed to be inclined and extend to the same extent as the locus. Thereby, even if the protrusion 3 is pushed backward while being pushed leftward, the protrusion of each engagement portion (33D, 33U) slides on the left edge of each engagement hole (11y, 15y). Thus, the protrusion 3 is appropriately retracted to prevent the protrusion 3 from being greatly displaced to the left. In addition, when the engagement holes (11y, 15y) are formed in such a shape that is inclined and extended, the shape can be made closer to the locus than in the case of a shape that extends straight forward and backward. It is easy to form the joint holes (11y, 15y) more compactly. In view of the fact that the locus is arcuate, the shape of each engagement hole (11y, 15y) may be formed in an arc shape that matches the locus. If it does in this way, each engagement hole (11y, 15y) can be made into the shape still closer to the said locus | trajectory, and it will become easy to form each engagement hole (11y, 15y) still more compactly.

In the present embodiment, the right edge of each engagement hole (11y, 15y) is also inclined to the same extent as the locus. Therefore, even when the protrusion 3 is pushed backward while being pushed rightward, the protrusion of each engagement portion (33D, 33U) slides on the right edge of each engagement hole (11y, 15y). In this way, the protrusion 3 is appropriately retracted, and the protrusion 3 is prevented from being greatly displaced to the right.

Further, in the contact Y, a support portion (support piece) 13b2 is provided in the same manner as in the first embodiment. By changing the bending depth of the support portion 13b2, the protrusion amount of the protrusion portion 3 in the initial state is provided. Etc. can be adjusted. In the contact Y, the protrusion of each engagement portion (33D, 33U) and the front edge of each engagement hole (11y, 15y) are in contact with each other in a state where the protrusion amount is adjusted to be less than the maximum. It is formed so as not to.

For example, as shown in FIG. 27, the upper engagement hole 15y has a gap γ between the protrusion of the upper engagement portion 33U and the front edge of the upper engagement hole 15y. Do not touch. If the protrusion of the upper engaging portion 33U and the front edge of the upper engaging hole 15y come into contact with each other, the protruding amount of the protruding portion 3 cannot be further increased. However, in this embodiment, since such a situation is avoided, adjustment of the protrusion amount of the protrusion part 3 is not prevented.

As described above, in the contact Y, the engaging portions (33D, 33U) are provided on the protruding portion 3 side (the protruding portion 3 side rather than the leaf spring portion 2), and the engaging portions (33D, 33U) are provided. 33U) engages with a portion on the housing portion 1 side (the housing portion 1 side rather than the leaf spring portion 2), thereby at least one direction (here, the left-right direction) orthogonal to the front (the protruding direction of the protruding portion 3). Displacement of the projecting portion 3 is suppressed. Therefore, it is possible to suppress the occurrence of buckling or the like in the contact Y. In addition, by suppressing the displacement of the protrusion 3 in the left-right direction, the relative displacement in the left-right direction between the lower convex portion 41D and the lower wall inclined portion 11x, and the upper convex portion 41U and the upper wall inclined It is possible to prevent relative displacement of the portion 15x in the left-right direction as much as possible, and to further stabilize the contact between the convex portions (41D, 41U) and the inclined portions (11x, 15x).

Further, in the contact Y, each engaging portion (33D, 33U) having a protrusion in the width direction (vertical direction) is provided to extend from the opposite side of the protruding portion 3 to the side connected to the leaf spring portion 2, The protrusion engages with a portion on the housing part 1 side. Further, the protrusions of the engaging portions (33D, 33U) are fitted into the engaging holes (11y, 15y) provided in the housing portion 1 so as to engage with the edges of the holes. As described above, by adopting a structure in which the protrusions of the respective engaging portions (33D, 33U) are caught on the edge of the hole provided in the housing portion 1, the displacement in the left-right direction of the contact Y is effectively suppressed with a simple configuration. Is possible.

In addition, as a mechanism for suppressing the displacement of the projecting portion 3 in the direction orthogonal to the front, another structure may be employed instead of the structure described above. An example of a contact (contact Y1) that employs another form of mechanism will be described below.

28 and 29 are external perspective views of the contact Y1 as seen from different directions, and FIG. 30 is a cross-sectional view taken from the upper viewpoint when the contact Y1 is cut along the center surface in the vertical direction. FIG. 31 is an external perspective view of the contact Y1 cut along the center surface in the vertical direction.

As shown in these figures, in the contact Y1, the formation of the respective engagement holes (11y, 15y) is omitted, but the lower engagement piece 14xD is provided at the lower portion of the front end of the left right wall portion 14b. Is provided, and an upper engagement piece 14xU is provided at an upper portion of the front end of the left right wall portion 14b. These engagement pieces (14xD, 14xU) are arranged symmetrically with respect to the center surface in the vertical direction of the contact Y, and are formed in the same shape and size. Each engagement piece (14xD, 14xU) extends slightly from the front end of the left right wall portion 14b to the left, and further extends substantially rearward from the left end. The portion extending substantially rearward extends in a direction inclined slightly to the left from the right rear direction. The inclination angle is set to be equal to the inclination of the left edge of each engagement hole (11y, 15y) in the contact Y.

On the other hand, the contact Y 1 is provided with a lower engagement portion 34 D and an upper engagement portion 34 U extending from the protruding portion 3. More specifically, the lower engagement portion 34D extends from the lower portion of the rear end of the right side wall portion 32R, and the upper engagement portion 34U extends from the upper portion of the rear end of the right side wall portion 32R. ing.

The lower engaging portion 34D extends to the upper space of the lower engaging piece 14xD, and has a protrusion protruding downward near its tip. The protrusion of the lower engagement portion 34D is disposed on the right side of the lower engagement piece 14xD, and a slight gap is provided between the protrusion and the lower engagement piece 14xD. The upper engaging portion 34D extends to the space below the upper engaging piece 14xU, and has a protrusion protruding downward near the tip thereof. The protrusion of the upper engagement portion 34D is disposed on the right side of the upper engagement piece 14xU, and a slight gap is provided between the protrusion and the upper engagement piece 14xU.

In the contact Y1, a portion extending substantially rearward of each engagement piece (14xD, 14xU) plays the same role as the left edge of each engagement hole (11y, 15y) in the contact Y. That is, even when the protruding portion 3 is pushed backward while being pushed leftward, the protrusion of each engaging portion (34D, 34U) extends substantially rearward of each engaging piece (14xD, 14xU). Thus, the protrusion 3 is appropriately retracted while sliding so that the protrusion 3 is largely displaced to the left.

That is, the above-described embodiment is an example in all respects, and should be considered as not restrictive. The technical scope of the present invention is shown not by the above description of the embodiment but by the scope of the claims, and is understood to include all modifications within the meaning and scope equivalent to the scope of the claims. Should.

The present invention can be used for contacts provided in, for example, portable communication devices.
