As a result, the hook portion 113a is hooked on the rear side of the bent pieces 251 and 252, and forward deviation from the inside of the housing H is avoided. As already described, the bent pieces 251 and 252 are hooked on the inner surface of the inner upper wall portion 211 while the extended portion 113 is hooked on the rear side.

The leaf spring portion 300 is composed of an upper leaf spring portion 300a and a lower leaf spring portion 300b. The lower leaf spring portion 300b has a band shape (the width direction is aligned with the vertical direction) bent at various points, extends from the lower position at the rear end of the left wall portion 240, and meanders left and right. It extends forward and is connected to the lower 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, when viewed in the width direction, the rear leaf spring portion 300b extends obliquely to the front and right from the lower end of the left wall portion 240, turns in the vicinity of the right wall portion 230, and extends obliquely 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 (the width direction is aligned with the vertical direction) bent at various points, extends from the upper position of the rear end of the right wall portion 230, and meanders left and right. It extends forward and is connected to the upper 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 to meander when viewed in the width direction. More specifically, when viewed in the width direction, the upper leaf spring portion 300a extends obliquely to the front and left from the rear end of the right wall portion 230, turns in the vicinity of the left wall portion 240, and extends obliquely to the front and right. , 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 . In the first element 100 , the vicinity of the upper end of the right intermediate component 116 contacts the upper right bent piece 251 , the vicinity of the upper end of the left intermediate component 116 contacts the upper left bent piece 252 , and the right intermediate component 116 contacts the upper end of the left intermediate component 116 . The vicinity of the lower end hits the lower right bent piece 261, and the vicinity of the lower end of the left intermediate component 116 hits the lower left bent piece 262, whereby the forward movable range of the guide part 114 is restricted.

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

An auxiliary upper wall portion 213 is provided at a central position near the right end of the upper wall portion 210 by bending leftward a portion of the right wall portion 240 protruding from the upper end. The auxiliary upper wall portion 213 is formed so as to be positioned on the same plane as the outer upper wall portion 212 . As a result, when the contact X is connected to the upper connection object (see FIG. 12A), the entirety of these (the outer upper wall portion 212 and the auxiliary upper wall portion 213) located on the plane is connected to the upper connection object. It is possible to solder to the flat surface of the board and fix it firmly.

An auxiliary lower wall portion 223 is provided at a central position near the right end of the lower wall portion 220 by bending a portion of the right wall portion 240 protruding from the lower end to the left. The auxiliary lower wall portion 223 is formed so as to be positioned on the same plane as the outer lower wall portion 222 . As a result, when the contact X is connected to the connection target on the lower side (see FIG. 12(b)), the whole of these (the outer lower wall portion 222 and the auxiliary lower wall portion 223) positioned on the plane is moved to the lower side. It can be firmly fixed by soldering to the plane to be connected.

FIGS. 12A and 12B schematically show usage patterns of the contacts X, FIG. 12A shows usage patterns when the second connection object Y2 is connected to the upper side of the contacts X, and FIG. A usage pattern in which the second connection object Y2 is connected to the lower side of the contact X is shown. The contact X shown in FIG. 12(a) has the outer upper wall portion 212 and the auxiliary upper wall portion 213 soldered to the horizontal surface of the connection target Y2, and the contact X shown in FIG. 12(b) has the outer lower wall portion. 222 and the auxiliary lower wall portion 223 are soldered to the plane of the connection object Y2. In performing the above soldering, when taking out the contacts X contained in the embossed tape (packing material), the central region of the upper wall portion 210 may be sucked by a 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 indicated by the dotted arrow, the slope portion 110 moves to the first position. It is pushed upward by the connection object 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 rearward and retreats.

In this way, when the slant portion 110 is pushed upward by the second connection object Y2, the contact X slides the second connection object Y2 on the slant portion 110 while the first element 100 is attached by the leaf spring portion 300. It is formed to move backward against the force. The first connection object Y1 is moved upward so as to pass over the slope portion 110, and the contact portion (near the first bent portion 111) corresponding to the front end of the first element 100 is aligned with the vertical rear surface of the first connection object Y1. Keep in contact. Thereby, the first connection object Y1 and the second connection object Y2 can be stably 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 (a second substrate having a horizontal surface) provided inside one of the housing parts 2 connection target Y2) and the side surface of the other housing part (first connection target Y1 having a vertical surface) are connected. 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 together in the vertical direction.

When the first connection target Y1 begins to push the slope portion 110 upward, the first element 100 moves backward against the bias of the leaf spring portion 300 while sliding the first connection target Y1 on the slope portion 110. . At the same time, since the hook portion 113a can be retracted within the housing H, the inclination angle θ of the slope portion 110 of the first element is increased by using the force pushed by the first connection target Y1. It is elastically deformable.

As described above, the first element 100 retreats due to the contraction of the leaf spring portion 300, and the change in the inclination angle θ due to the elastic deformation of the first element 100 causes the distance between the first connection object Y1 and the contact X in the front-rear direction to increase. Even if there is some variation, it is possible to use the contact X appropriately. In this manner, the contact X widens the allowable range of the positional relationship in the front-rear direction with respect to the first connection object Y1, and is designed to 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. 13(a) to (e), the distance is different, and the amount of rearward movement of the front end of the first element 100 is 0.15 mm, 0.4 mm, 0.6 mm, and so on. A case of 0.8 mm and a case of 1.0 mm are shown, respectively. In addition, in FIG.13(e), it displays so that the 1st bending part 111 vicinity of the 1st element 100 may be seen through.

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

In the case of FIG. 13E, 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 made longer 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 terms of widening 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 approximately zero.

Further, in the present embodiment, when pushed by the first connection object Y1, the first element 100 is elastically deformed so that the inclination angle θ increases, so that the front-rear dimension of the first element 100 itself is reduced, and the leaf spring portion is reduced accordingly. Since the amount of contraction required for 300 can be reduced, it is advantageous in reducing the size of the contact X in the front-rear direction. Furthermore, by making it elastically deformable so as to increase the inclination angle θ, even if the first connection target Y1 is difficult to slide on the surface of the slope portion 110, the first element 100 is elastically deformed so that it becomes easy to slide. Thus, problems such as the first connection target Y1 being caught on the surface of the slope portion 110 can be 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 to the right when viewed forward, and the right edge is inclined to the left when viewed forward. As a result, even if a foreign object or the like hits the slope portion 110 in the left-right direction, the foreign object or the like can be deflected in the direction of the inclination, and unintended deformation or breakage of the contact X can be suppressed as much as possible. The horizontal dimension of the slope portion 110 is about 0.88 mm at the rear end (which can be regarded as the lower end) and about 0.5 mm at the front end (which can be regarded 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 on the lower surface of the upper wall portion 210 and retreats, and the lower sliding contact portion 115a moves toward the upper surface of the lower wall portion 220. , so that the first element 100 moves straight rearward. As shown in FIG. 8, the lower sliding contact portion 115a is arranged a distance D behind the upper sliding contact portion 117a. Therefore, the force in the rotational direction (force to rotate the first element 100 in the direction indicated by the dashed arrow in FIG. 8) generated when the slope portion 110 is pushed by the first connection object Y1 is transferred to these sliding contact portions 115a. , 117a and can restrain the movement of the first element 100 in the direction of rotation. Further, by moving the first element 100 straight rearward, the contraction direction of the leaf spring portion 300 becomes straight, and buckling of the leaf spring portion 300 can be prevented as much as possible.

Furthermore, the contact X is designed so that the length of the electrical path between the connection objects to be connected is short. More specifically, in the case where the connection objects are connected as shown in FIG. 12(a), the first connection object Y1 includes the slope portion 110, the right intermediate component portion 116, and the upper sliding contact portion 117a. , and the auxiliary upper wall portion 213 in this order, and are electrically connected to the second connection object Y2. On the other hand, in the case where the connection objects are connected to each other as shown in FIG. and electrically connected to the second connection object Y2. In any of these cases, the length of the electrical path is significantly shortened compared to, for example, the case where the connection objects are connected only through the path through the leaf spring portion 300, and good high-frequency characteristics can be obtained. Is possible.

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

Therefore, according to the contact X, even if the first connection object Y1 is moved in a direction substantially orthogonal to the projecting direction of the contact portion (the front end of the first element 100), the connection object can be It is possible to connect them properly.

In the contact X, the slope portion 110 protrudes forward from the opening of the housing H formed in the second element 200, and the spring portion 300 is housed inside the housing H. As shown in FIG. Therefore, the contact X can sufficiently protect the spring portion 300 by the housing H. FIG.

The contact X has a slanted portion 110 that faces obliquely downward, and is used with the slanted portion 110 pushed upward by the first connection target Y1. and a guide portion 114 that supports the lower end portion of the slope portion 110 . The guide portion 114 is connected to the lower end portion of the inclined surface portion 110 and is connected via a lower component portion 115 having a lower sliding contact portion 115a that slides on the lower surface of the housing H and an intermediate component portion 116 that extends vertically. an upper constituent portion 117 having an upper sliding contact portion 117a that is connected to the lower constituent portion 115 through the upper constituent portion 115 and is in sliding contact with the upper surface in the housing H; Therefore, the contact X can slide the guide portion 114 stably within the housing H while the slope portion 110 is supported by the guide portion 114 .

In the contact X, the two intermediate constituent portions 116 are arranged with their positions shifted to the left and right, and of the two spring portions (the upper leaf spring portion 300a and the lower leaf spring portion 300b) arranged to be shifted from each other vertically, the lower The side leaf spring portion 300b extends from the left intermediate component portion 116, and the upper leaf spring portion 300a extends from the right intermediate component portion 116. As shown in FIG. Further, the two spring portions are rotationally symmetrical by 180 degrees with respect to an axis (axis Z shown in FIG. 5) extending forward and backward. Therefore, the unevenness 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 an inner upper wall portion 211 (an example of the inner side wall portion) and an outer upper wall portion 212 (an example of the outer side wall portion) above (an example of the lateral side) of the leaf spring portion 300 . Inner lower wall portion 221 (an example of the inner side wall portion) and outer lower wall portion 222 (an example of the outer side wall portion) below the upper wall portion 210 (an example of the overlapping side wall portion) and the leaf spring portion 300 (an example of the lateral side). example) has a lower wall portion 220 (an example of an overlapping side wall portion) formed overlapping. As described above, the contact X has an overlapping side wall portion formed by stacking two plate members (the inner side wall portion and the outer side wall portion), so that the contact X has a high rigidity and a very high strength. More reliable protection is possible.

Further, the second element 200 is formed by bending the outer upper wall portion 212 inward to form an upper right bent piece portion 251 and an upper left bent piece portion 252 , and the outer lower wall portion 222 to an inward bend. It has a lower right bent piece portion 261 and a lower left bent piece portion 262 . The upper right bent piece portion 251 and the upper left bent piece portion 252 regulate the forward movable range of the first element 100, and are hooked on the inner surface of the inner upper wall portion 211 to form the outer upper wall portion 212 and the inner upper wall. The displacement 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 hooked on the inner surface of the inner lower wall portion 221 to form the outer lower wall portion 222 and the inner lower wall portion. The displacement of the wall portion 221 is suppressed.

In this manner, 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 (the inner side wall portion and the outer side wall portion) are easily realized by providing the bent pieces. Therefore, the contact X has a relatively simple structure and high performance, which is advantageous in terms of simplification of the manufacturing process.

Also, the front end of the first element 100 (in the vicinity of the first bent portion 111) of the contact X may be formed in an R shape (rounded shape) by press working in advance, for example. FIG. 14 shows a perspective view of the contact X1 having such an R shape, FIG. 15 shows a front view of the contact X1, and FIG. 16 shows a bottom view of the contact X1. there is By giving the front end portion of the first element 100 an R shape, for example, even if the rear surface of the first connection target Y1 is slightly inclined, the contact state between the first element 100 and the first connection target Y1 can be easily maintained appropriately. It becomes possible to
