Description

The present invention relates to contacts used for electrical connection between objects to be connected.

Various parts necessary for ensuring the function of the device are arranged in various electric devices such as mobile phones. In addition, contacts may be used to electrically connect these parts (connection targets) to each other.

There are various such contacts, but as one kind of the contact, the one disclosed in Patent Document 1 having 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, and as shown in FIGS. 1 to 3 of Patent Document 1, an inverted U-shaped contact portion 14 is formed from the housing 12. Is provided so as to project, and the contact portion 14 is urged in the projecting direction by the spring portion 16 in the housing 12.

In this way, a type in which a contact portion (a portion in contact with one of the connection targets) formed by bending a conductive plate material having a predetermined shape and projecting retractably is urged in the projecting direction by a spring portion is described below for convenience. It is called "folding type urging type". The folding type urging type contact can reduce the number of parts at the time of manufacturing as much as possible, and can also form a housing to protect the spring portion.

Each of the left and right upper component portions 117 is provided with an upper sliding contact portion 117a that is in sliding contact with the lower surface of the upper wall portion 210 (which can also be seen as the upper surface in the housing H). The upper sliding contact portion 117a can slide in the front-rear direction with respect to the lower surface of the upper wall portion 210. Each of the left and right upper sliding contact portions 117a is a portion that has been pressed so as to form an upward convex portion extending to the left and right.

The slope portion 110 is formed in a planar shape (the width direction coincides with the left-right direction) extending in a slanted manner with respect to the front-rear direction. As shown in FIG. 8, the inclination angle θ of the slope portion 110 is set to about 35 degrees with respect to the front-rear direction in the example of the present embodiment, but other angles (for example, from 30 degrees to 30 degrees) depending on the application and the like. It may be set to any angle within the range of 45 degrees).

The stretched portion 113 is formed in a band shape extending from the upper end of the slope portion 110 (the width direction coincides with the left-right direction), and a hooking portion 113a is provided at the tip thereof. In the stretched portion 113, the portion from the first bent portion 111 to the second bent portion 112 extends substantially parallel to the slope portion 110 by a length of about one-third of the length at which the slope portion 110 extends. Further, the stretched portion 113 extends substantially straight from the second bent portion 112 to the hooked portion 113a. The first bent portion 111 is a portion of the upper end portion of the slope portion 110 that is bent backward by about 180 degrees.

The hook portion 113a is formed in a plane shape facing the lower surface of the upper wall portion 210, and protrudes in both the left and right directions from the other portions of the extension portion 113 when viewed from the front. The right end of the hooking portion 113a is arranged on the rear side of the upper right side bent piece portion 251 and the left end portion of the hooking portion 113a is arranged on the rear side of the upper left side bent piece portion 252. As a result, the hook portion 113a is hooked on the rear side of the bent piece portions 251,252, and the deviation from the inside of the housing H to the front is avoided. As already described, in each of the bent piece portions 251,252, the stretched portion 113 is hooked on the rear side and is hooked on the inner surface of the inner upper wall portion 211.

The leaf spring portion 300 includes an upper leaf spring portion 300a and a lower leaf spring portion 300b. The lower leaf spring portion 300b has a band shape bent at each location (the width direction coincides with the vertical direction), extends from the lower position of the rear end of the left wall portion 240, and meanders to the left and right. It extends forward and is connected to the lower position of the left end of the left intermediate component 116. That is, the lower leaf spring portion 300b extends from the rear end of the left wall portion 240 and is formed inside the housing H so as to meander when viewed in the width direction. More specifically, the rear leaf spring portion 300b extends diagonally forward and to the right from the lower end of the left wall portion 240 when viewed in the width direction, turns in the vicinity of the right wall portion 230, and extends diagonally to the front and left. It is connected to the left end of the left intermediate component 116 in the vicinity of the left wall portion 240.

The upper leaf spring portion 300a has a band shape bent at each location (the width direction coincides with the vertical direction), extends from the upper position of the rear end of the right wall portion 230, and meanders to the left and right. It extends forward and is connected to the upper position of the right end of the right intermediate component 116. That is, the upper leaf spring portion 300a extends from the rear end of the right wall portion 230 and is formed inside the housing H so as to meander when viewed in the width direction. More specifically, the upper leaf spring portion 300a extends diagonally forward and left from the rear end of the right wall portion 230 when viewed in the width direction, turns in the vicinity of the left wall portion 240, and extends diagonally forward and right. , It is connected to the right end of the right intermediate component 116 in the vicinity of the right wall portion 230.

The first element 100 is urged forward by the leaf spring portion 300. Further, in the first element 100, the vicinity of the upper end of the right intermediate configuration portion 116 corresponds to the upper right bending piece portion 251 and the vicinity of the upper end of the left intermediate configuration portion 116 corresponds to the upper left bending piece portion 252, and the right intermediate configuration portion 116 The vicinity of the lower end of the guide portion 114 corresponds to the lower right bent piece portion 261 and the vicinity of the lower end of the left intermediate component 116 hits the lower left bent piece portion 262, thereby restricting the forward movable range of the guide portion 114.

In the initial state, due to the elastic force of the leaf spring portion 300, each of the bent piece portions 251,252, 261,262 receives a slight load (initial load) forward from the guide portion 114. Therefore, due to the preload in the initial state, the guide portion 114 is in close contact with each of the bent piece portions 251,252, 261,262, and the position of the guide portion 114 is stable. In the initial state, such an initial load may not occur.

An auxiliary upper wall portion 213 is provided at a position near the center near the right end of the upper wall portion 210 by bending the portion protruding from the upper end of the right wall portion 240 to the left. The auxiliary upper wall portion 213 is formed so as to be located on the same plane as the outer upper wall portion 212. As a result, when the contact X is connected to the upper connection target (see FIG. 12A), all of them (outer upper wall portion 212 and auxiliary upper wall portion 213) located on the plane are connected to the upper connection target. It can be soldered to the flat surface of the surface and firmly fixed.

An auxiliary lower wall portion 223 is provided at a position near the center near the right end of the lower wall portion 220 by bending the portion protruding from the lower end of the right wall portion 240 to the left. The auxiliary lower wall portion 223 is formed so as to be located on the same plane as the outer lower wall portion 222. As a result, when the contact X is connected to the lower connection target (see FIG. 12B), all of them (outer lower wall portion 222 and auxiliary lower wall portion 223) located on the plane thereof are on the lower side. It can be soldered to the flat surface to be connected and firmly fixed.

FIG. 12 schematically shows a usage pattern of the contact X, FIG. 12A shows a usage pattern when the second connection target Y2 is connected to the upper side of the contact X, and FIG. 12B shows a usage pattern. The usage mode when the second connection target Y2 is connected to the lower side of the contact X is shown. In the contact X shown in FIG. 12A, the outer upper wall portion 212 and the auxiliary upper wall portion 213 are soldered to the horizontal plane of the connection target Y2, and the contact X shown in FIG. 12B is the outer lower wall portion. The 222 and the auxiliary lower wall portion 223 are soldered to the flat surface of the connection target Y2. In performing the above soldering, when the contact X contained in the embossed tape (packing material) is taken out, the central region of the upper wall portion 210 may be sucked by the suction nozzle and taken out.

In both cases of FIGS. 12A and 12B, when the first connection target Y1 is relatively moved upward from the lower position of the slope portion 110 as shown by the dotted arrow, the slope portion 110 becomes the first. It is pushed upward by the connection target Y1. As a result, the second connection target Y2 slides upward on the slope portion 110, and at the same time, the slope portion 110 is pushed backward and retracts.

In this way, in the contact X, when the slope portion 110 is pushed upward by the second connection target Y2, the first element 100 is attached by the leaf spring portion 300 while sliding the second connection target Y2 on the slope portion 110. It is formed to move backward against the force. The first connection target Y1 is moved upward so as to exceed the slope portion 110 as it is, and the contact portion (near the first bent portion 111) corresponding to the front end of the first element 100 becomes the vertical rear surface of the first connection target Y1. It shall be in contact. As a result, the first connection target Y1 and the second connection target Y2 can be stably and electrically connected.

As a specific example of use of the contact X, in a thin electronic device such as a smartphone formed by combining upper and lower housing parts, a substrate (having a horizontal plane) provided inside one housing part is provided. 2 Examples include connecting the connection target Y2) and the side surface of the other housing part (the first connection target Y1 having a vertical surface). In this case, the first connection target Y1 pushes the slope portion 110 in the step of bringing the upper and lower housing parts closer to each other in the vertical direction.

When the first connection target Y1 starts pushing the slope portion 110 upward, the first element 100 moves backward against the urgency of the leaf spring portion 300 while sliding the first connection target Y1 on the slope portion 110. .. At the same time, since the hooking portion 113a is retractable in the housing H, the tilt angle θ of the slope portion 110 of the first element becomes large by utilizing the force pushed by the first connection target Y1. It is elastically deformable.

In this way, the retracting of the first element 100 due to the contraction of the leaf spring portion 300 and the change in the inclination angle θ due to the elastic deformation in the first element 100 cause the distance between the first connection target Y1 and the contact X in the front-rear direction. It is possible to properly use the contact X even if there is some variation. As described above, the contact X is considered to widen the allowable range of the positional relationship in the front-rear direction with the first connection target Y1 and widen the working area.

FIG. 13 schematically shows the state of the contact X in each case where the distance in the front-rear direction from the first connection target Y1 is different. Each of FIGS. 13 (a) to 13 (e) has a different distance, and the amount of movement of the front end of the first element 100 to the rear is 0.15 mm, 0.4 mm, and 0.6 mm. The case of 0.8 mm and the case of 1.0 mm are shown respectively. In FIG. 13 (e), the vicinity of the first bent portion 111 of the first element 100 is displayed so as to be seen through.

In any of the cases of FIGS. 13A to 13E, the contact X can stably and electrically connect the first connection target Y1 and the second connection target Y2. Further, the contact force between the contact X and the first connection target Y1 is about 0.2 N in the case of the smallest figure 13 (a) and about 1.3 N in the case of the largest figure 13 (e), both of which are. It is within the proper range. In this way, the contact X has a working area of at least 0.85 mm (= 1.0 mm-0.15 mm).

In the case of FIG. 13 (e), the interference between the first bent portion 111 and the upper wall portion 210 is prevented by fitting the first bent portion 111 into the interference prevention recess 210s. By providing the interference prevention recess 210s in this way, the slope portion 110 can be lengthened while preventing interference with the upper wall portion 210, and the positional relationship between the contact X and the first connection target Y1 in the front-rear direction. It is advantageous in that it widens the allowable range of. In the case of FIG. 13 (e), the distance L between the opening of the housing H and the front end of the first element 100 is almost zero.

Further, in the present embodiment, when pushed by the first connection target Y1, the first element 100 itself is elastically deformed so that the inclination angle θ becomes large, so that the dimension in the front-rear direction of the first element 100 itself becomes small, and the leaf spring portion is correspondingly small. Since the amount of shrinkage required for the 300 can be reduced, it is advantageous in reducing the size of the contact X in the front-rear direction. Further, by making it elastically deformable so that the inclination angle θ becomes large, even if the first connection target Y1 is hard to slip on the surface of the slope portion 110, the first element 100 is elastically deformed so as to be slippery. Therefore, problems such as the first connection target Y1 being caught on the surface of the slope portion 110 are avoided.

Further, as shown in FIG. 4 and the like, the left and right edges of the slope portion 110 are inclined inward when viewed forward. That is, the left edge of the slope portion 110 is inclined toward the right side when viewed forward, and the right edge is inclined toward the left side when viewed forward. As a result, even if a foreign substance or the like hits the slope portion 110 in the left-right direction, the foreign substance or the like can be parried in the direction of the inclination to suppress unintended deformation or damage of the contact X as much as possible. The left-right dimension of the slope 110 is about 0.88 mm at the rear end (which can also be seen as the lower end) and about 0.5 mm at the front end (which can also be seen as the upper end). There is.

Further, when the slope portion 110 is pushed by the first connection target Y1, the upper sliding contact portion 117a slides back on the lower surface of the upper wall portion 210, and the lower sliding contact portion 115a slides back on the upper surface of the lower wall portion 220. The first element 100 moves straight backward so as to slide back. As shown in FIG. 8, the lower sliding contact portion 115a is arranged behind the upper sliding contact portion 117a by a distance D. Therefore, the force in the rotation direction generated by the slope portion 110 being pushed by the first connection target Y1 (the force for rotating the first element 100 in the direction indicated by the broken line arrow in FIG. 8) is applied to these sliding contact portions 115a. , 117a can be effectively received, and the movement of the first element 100 in the rotation direction can be suppressed. Further, by moving the first element 100 straight to the rear, the contraction direction of the leaf spring portion 300 is also straightened, and it is possible to prevent buckling of the leaf spring portion 300 as much as possible.

Further, the contact X is designed so that the length of the electric path between the connected objects to be connected is shortened. More specifically, in the case where the connection targets are connected to each other as shown in FIG. 12A, the first connection target Y1 is the slope portion 110, the right intermediate component portion 116, and the upper sliding contact portion 117a. , And are electrically connected to the second connection target Y2 through a path passing through the auxiliary upper wall portion 213 in order. On the other hand, in the case where the connection targets are connected to each other as shown in FIG. 12B, the first connection target Y1 is a path that sequentially passes through the slope portion 110, the lower sliding contact portion 115a, and the auxiliary lower wall portion 223. It is electrically connected to the second connection target Y2 through the passage. In any of these cases, the length of the above-mentioned electric path is significantly shorter than that in the case where the connection targets are connected to each other only through the path via the leaf spring portion 300, for example, and good high frequency characteristics and the like are obtained. It is possible.

As described above, the contact X is a contact that electrically connects the first connection target Y1 and the second connection target Y2, and is the first element 100 connected to the first connection target Y1 and the second connection target. The conductive plate material is bent so as to have a second element 200 connected to Y2, a spring portion 300 connected to each of the first element 100 and the second element 200, and a spring portion 300 for urging the first element 100 forward. Is formed. Further, in the contact X, the first element has a slope portion 110 inclined with respect to the front-rear direction, and when the slope portion 110 is pushed by the first connection target Y1 in a direction substantially orthogonal to the front-rear direction, the first element is first. The first element 100 is formed so as to move backward against the bias of the spring portion 300 while sliding the connection target Y1 on the slope portion 100.

Therefore, according to the contact X, even if the first connection target Y1 is moved in a direction substantially orthogonal to the protruding direction of the contact portion (front end of the first element 100) even though it is a bent type urging type, the connection target is connected. It is possible to connect each other properly.

At the contact X, the slope portion 110 projects forward from the opening of the housing H formed in the second element 200, and the spring portion 300 is housed in the housing H. Therefore, the contact X can sufficiently protect the spring portion 300 by the housing H.

The contact X is used in which the slope portion 110 faces diagonally downward and the slope portion 110 is pushed upward by the first connection target Y1 and the first element 100 is connected to the spring portion 300. In addition, a guide portion 114 that supports the lower end portion of the slope portion 110 is provided. The guide portion 114 is connected to the lower end portion of the slope portion 110, and is via a lower component portion 115 having a lower sliding contact portion 115a that is slidably contacted with the lower surface of the housing H and an intermediate component portion 116 extending vertically. It is provided with an upper component portion 117 having an upper sliding contact portion 117a which is connected to the lower component portion 115 and which is slidably contacted with the upper surface in the housing H. Therefore, the contact X can stably slide the guide portion 114 in the housing H while allowing the slope portion 110 to be supported by the guide portion 114.

In the contact X, the two intermediate component 116s are arranged so as to be displaced to the left and right, and the lower of the two spring portions (upper leaf spring portion 300a and lower leaf spring portion 300b) arranged so as to be vertically displaced. The side leaf spring portion 300b is formed so as to extend from the left intermediate constituent portion 116, and the upper leaf spring portion 300a extends from the right intermediate constituent portion 116. Further, the two spring portions are rotationally symmetric by 180 degrees with respect to an axis extending back and forth (axis Z shown in FIG. 5). Therefore, the bias of the characteristics of the spring portion 300 is suppressed, and the first element 100 can be easily moved straight in the front-rear direction.

The second element 200 is formed by overlapping the inner upper wall portion 211 (an example of the inner side wall portion) and the outer upper wall portion 212 (an example of the outer side wall portion) above the leaf spring portion 300 (an example on the side). The upper wall portion 210 (an example of the overlapping side wall portion) and the inner lower wall portion 221 (an example of the inner side wall portion) and the outer lower wall portion 222 (an example of the outer side wall portion) below the leaf spring portion 300 (an example of the side). It has a lower wall portion 220 (an example of an overlapping side wall portion) formed by overlapping (one example). As described above, the contact X has a high rigidity because it has an overlapping side wall portion formed by overlapping two plate materials (inner side wall portion and outer side wall portion), and has extremely high strength. It is possible to protect more reliably.

Further, the second element 200 is formed by being bent inward from the outer upper wall portion 212 to the upper right side bent piece portion 251 and the upper left side bent piece portion 252, and the outer lower wall portion 222. It has a lower right bent piece portion 261 and a lower left bent piece portion 262. The right upper bent piece portion 251 and the upper left bent piece portion 252 regulate the forward movable range of the first element 100, and are caught on the inner surface of the inner upper wall portion 211, and the outer upper wall portion 212 and the inner upper wall. The misalignment of the portion 211 is suppressed. The lower right bent piece portion 261 and the lower left bent piece portion 262 regulate the forward movable range of the first element 100, and are caught on the inner surface of the inner lower wall portion 221 to be caught on the inner surface of the inner lower wall portion 221 and the outer lower wall portion 222 and the inner lower side. Suppresses the misalignment of the wall portion 221.

As described above, in the contact X, the limitation of the movable range of the first element 100 and the suppression of the positional deviation between the plate members (inner side wall portion and outer side wall portion) can be easily realized by providing the bent piece portion. Therefore, the contact X has a relatively simple structure and high performance, and is also advantageous in simplifying the manufacturing process.

Further, at the front end portion (near the first bent portion 111) of the first element 100 in the contact X, an R shape (a rounded shape) may be adopted, for example, by performing a press working in advance. FIG. 14 shows a perspective view of the contact X1 in an example having such an R shape, FIG. 15 shows an external view of the front viewpoint of the contact X1, and FIG. 16 shows an external view of the downward viewpoint of the contact X1. There is. By giving the front end of the first element 100 an R shape, for example, even if the rear surface of the first connection target Y1 is slightly tilted, it is easy to properly maintain the contact state between the first element 100 and the first connection target Y1. It becomes possible to do.
