Such a micro-blade switch, for example, as shown in japanese patent laid-open publication No. 2007-234510 and japanese patent laid-open publication No. 2011-070933, does not have an adjustment mechanism, and cannot be provided at the contact position or the interval between the movable contact portion of the movable contact piece and the fixed contact portion provided in the fixed contact piece.

The micro blade switch for the assembly such as the compound operation switch has fixed ON/OFF action position, and the action position (such as the pushing-down degree of the operating lever and the pressing degree of the key) set by the compound operation switch is also fixed, so that the micro blade switch cannot match with the operation preference or habit of different users, and thus the user feels that the operation is not easy.

Thus, the operation comfort of playing the game is poor, and even the result of the competition can be influenced when the competitive game such as e-sport is played.

In addition, in specifications of products such as a micro blade switch, a tolerance is provided for the product specifications such as an operation position, and the specifications are different within a tolerance range. Therefore, when a plurality of micro-blade switches are used, there is a possibility that the micro-blade switches used are not identical to the compound operation switches in operation positions, and the game feeling is not smooth due to the difference in operation positions.

Detailed Description

The following detailed description is based on the drawings attached to embodiments of the invention. Fig. 1 is a perspective view of a composite operation switch a in which a plurality of micro blade switches 12 of the present invention are arranged, and is an operation panel for a television game machine for business use or home use, which is not shown. Fig. 2 is a section A-A of fig. 1. The composite operation switch a is one example of the application of the micro blade switch 12, and is not limited to the illustration. The micro blade switch 12 is also used for various other applications such as opening and closing a door, detecting a position of a door, and detecting a precise position such as initial position detection of an incremental encoder or a stepping motor.

In fig. 1 to 2, the operation lever 11 of the composite operation switch a is composed of a lever 11a and a ball grip 11b attached to the upper end portion of the lever 11 a. The operation lever 11 is attached to the base plate 16 via an axial bearing portion 11c, is swingable 360 degrees starting in directions indicated by arrows 11g, 11h, and is automatically returned to the self-holding position by the automatic return mechanism B using a compression spring 11 f.

As shown in fig. 1 and 2, each of the micro-blade switches 12, 12 mounted on the circuit board 14 is sandwiched between a base plate 16 and a cam plate 17 mounted on the base plate 16. The sandwiching structure is configured to engage the locking portions 16b of the four locking members 16a provided on the four sides of the base plate 16 with the four engaging portions 17b provided on the cam plate 17. The operation lever 11 is provided with an operation key pressing portion 11d, and the micro-blade switches 12, 12 are arranged around the operation key pressing portion 11d as shown in fig. 3. The symbol 14a in fig. 1 is a connector terminal for transmitting signals of the micro blade switches 12, 12 to an external controller; reference numeral 14b in fig. 3 denotes an insertion hole of the lever 11a of the operation lever 11.

When the player holds the ball grip 11b and pushes the lever 11 in any direction after the game starts, the operation key pressing portion 11d presses or separates the operation keys 15, 15 of the micro-blade switches 12, 12 arranged around the operation key pressing portion, thereby performing the ON/OFF operation of the micro-blade switches 12, 12. As shown in fig. 2, the rocking angle of the operation lever 11 is limited by the abutment of a stopper member 11i attached to the lower end portion thereof against a stopper hole 17a provided in the cam plate 17.

Fig. 4 is a perspective view of the micro blade switch 12 of the present invention, in which the operation key 15 and the external connection terminals 18a and 18b are protruded outward from the case 12 a. Fig. 5 is a plan view of the micro blade switch 12 of fig. 4, as seen from the arrow 41a direction, and the operation key 15 is slidably accommodated in the accommodating portion 12d provided in the case 12a in the arrow 51 direction. Fig. 6 is a side view of the micro blade switch 12 of fig. 4, as seen from the arrow 41b direction, and a rotation operation portion 13a is provided on the opposite side of the operation key 15 of the case 12 a. Then, a screwdriver or the like is inserted into the lateral groove 13b provided in the rotation operation portion 13a, and the screwdriver is rotated in the direction of arrow 61 to adjust the micro blade switch 12.

As shown in fig. 7, the micro-blade switch 12 includes a case 12a and a cover 12b covering the case 12 a. For example, a coil spring 15b made of SUS, which biases the operation button 15 made of POM in the protruding direction with respect to the case 12a, a movable tab 19a and a fixed tab 19d made of flexible deformable, and an adjusting member 13 made of POM and external connection terminals 18a, 18b made of silver-plated copper alloy are provided in the case 12a made of PBT, and locking members 12h, 12h (only three are shown) provided on four sides of the cover 12b made of PBT are joined to locking protrusions 12i, 12i (only two are shown) provided in the case 12a, so that the members and the like are housed in the inside. The gold-plated silver movable contact portion 20a is attached to the hole portion 19c of the movable contact piece 19a via a joint; similarly, the gold-plated silver fixed contact portion 20b is also attached to the hole portion 19e of the fixed tab 19d by a bonding material.

The distal end portion 19b of the movable tab 19a is engaged with a movable tab addition protrusion 15a provided on the operation key 15, and is lifted by the elastic force of the coil spring 15b, so that the movable tab 19a is further deflected in the bending direction. The height adjusting portion 19f provided on the fixing tab 19d is in contact with one of the first to fifth cam portions 13c1 to 13c5 of the cam portions 13c provided at the respective different heights of the adjusting member 13. The click convex portion 19g provided at the other end portion of the fixing tab 19d is engaged with the engagement concave portion provided at the rotation preventing portion 13d of the adjustment member 13, preventing the complex operation switch a from being rotated unexpectedly in operation.

Next, the operational relationship between the respective members of the micro blade switch 12 shown in the exploded perspective view of fig. 7 will be described with reference to the sectional view of fig. 8. The movable tab 19a and the fixed tab 19d are connected to the external connection terminals 18b and 18a, respectively, and are assembled in the case 12 a. In this way, the movable tab 19a and the external connection terminal 18b, and the fixed tab 19d and the external connection terminal 18a are surely electrically connected, and in order to prevent the components from loosening when assembled in the case 12a, the movable tab 19a and the fixed tab 19d are provided with spring portions 19h and 19i using slit grooves, as shown in fig. 7. The movable tab 19a, the fixed tab 19d, and the external connection terminals 18a and 18b are respectively overlapped and compressed and connected by being placed in the slits 21 and 22 provided in the case 12a, and the spring portions 19h and 19i are flattened to achieve reliable electrical connection and absorb looseness caused by assembly.

The movable tab 19a engages with a movable tab attaching projection 15a provided on the operation key 15, is lifted by the coil spring 15b, and further adds flexure in the bending direction. Therefore, at normal times, the movable contact portions 20a and the fixed contact portions 20b of the movable contact pieces 19a and the fixed contact pieces 19d do not contact each other. However, when the pressing force acts on the operation key 15 in the direction of arrow 81, the coil spring 15b is contracted, and the amount of deflection of the movable contact piece 19a is reduced, so that the movable contact portion 20a is brought into contact with the fixed contact portion 20 b. In this way, the micro-blade switch 12 is turned ON by being pressed by the operation key 15. As described above, the operation key 15 is biased in the protruding direction against the case 12a by the coil spring 15b, and as shown in fig. 8, the ear 15e of the operation key 15 is engaged with the inner case 12c of the case 12a, so that the operation key 15 does not come out of the case 12 a.

As is clear from fig. 8, the force applied to the operation key 15 is not directly transmitted to the movable tab 19a, but the amount of added deflection in the bending direction of the movable tab 19a is reduced. The movable tab 19a flexes only at a time constant determined by the elastic force and the mass of the movable contact portion 20a, and even if a strong force is briefly applied to the operation key 15, the movable tab 19a is not deformed by the movement amount thereof. As described above, the tip end portion of the movable tab 19a of the micro-blade switch 12 of the present invention is locked to the movable tab addition protrusion 15a of the operation key 15 in a state of being additionally deflected, and the state of being additionally deflected is released after the operation key 15 is pressed, and when the micro-blade switch returns to the original position, the movable contact portion 20a and the fixed contact portion 20b are brought into contact with each other to be turned ON, which is very suitable for realizing the composite operation switch a with excellent durability. Furthermore, the above structure does not give a click action sound as in the conventional snap action mechanism switch, so that the generation of noise can be avoided and enjoyed.

The adjustment member 13 is accommodated in an adjustment member accommodation portion 12g provided in the case 12a, and is rotatable in the axial direction. As shown in fig. 9 and 10, the adjustment member 13 includes a cam portion 13c, a rotation preventing portion 13d, and a rotation operating portion 13a. The cam portions 13c (first to fifth cam portions 13c1 to 13c 5) are a plurality of different stages in height. Further, by rotating the fixed contact portion 20b with a screwdriver on the lateral groove 13b provided in the rotation operation portion 13a, one of the cam portions 13c of the plurality of stages of the first to fifth cam portions 13c1 to 13c5 is brought into contact with the height adjustment portion 19 f. Therefore, by the rotational operation of the adjustment member 13, the first to fifth cam portions 13c1 to 13c5 selected by the height adjustment portion 19f are changed, and the gap between the fixed contact portion 20b of the fixed tab 19d and the movable contact portion 20a of the movable tab 19a is adjusted.

As shown in fig. 8, the click protruding portion 19g provided in the fixing tab 19d and one of the first click recessed portion 13d1 to the fifth click recessed portion 13d5 of the rotation preventing portion 13d are engaged with each other, thereby preventing the rotation of the adjustment member 13. The rotation preventing portion 13d is provided in the same phase as the first to fifth click recesses 13d1 to 13d5 of the cam portions 13c of the plurality of stages corresponding to the first to fifth cam portions 13c1 to 13c5, so that the height adjusting portion 19f does not move to an unstable step portion of the cam portion 13c when the adjusting member 13 is rotated and operated at the click stop position of the adjusting member 13.

In this way, by the click mechanism in which the click protruding portion 19g is placed in one of the first click recessed portion 13d1 to the fifth click recessed portion 13d5 of the rotation preventing portion 13d, not only the loosening of the rotation around the rotation axis, which is the adjustment operation direction of the adjustment member 13, can be suppressed, but also the position of the adjusted fixing tab 19d can be stably held by the phase alignment of the first cam portion 13c1 to the fifth cam portion 13c5 of the cam portion 13c and the first click recessed portion 13d1 to the fifth click recessed portion 13d 5. Further, the cam portion 13c is held at five stages of the first to fifth cam portions 13c1 to 13c5, so that the adjustment resolution is excellent, and the movement accuracy of the height adjustment portion 19f can be obtained to be balanced best.

Further, as shown in fig. 8, the click protruding portion 19g urges the rotation preventing portion 13d in the direction of the arrow 81, so that not only the looseness of the rotation shaft direction of the adjustment member 13 can be suppressed, but also the adjustment can be performed with high accuracy.

The rotation operation portions 13a, 13a are provided outside the micro-blade switches 12, 12 in fig. 3, on the opposite side to the operation keys 15. Accordingly, the rotation operation portions 13a, 13a of the micro-blade switches 12, 12 are exposed to the outside, respectively, so that the adjustment operation is easy.

External connection terminals 18a and 18b are provided on different sides of the case 12 a. In general, it is advantageous to provide external connection terminals on the same side of the case 12a for soldering the circuit board 14. However, such terminal arrangement causes the case 12a of the micro-blade switch 12 to be suspended from the circuit board 14 by fixing only one surface thereof. The miniature blade switch 12 of the present invention has external connection terminals 18a, 18b provided on different sides, so that the case 12a of the miniature blade switch 12 is surely mounted on the circuit board 14, and the adjustment operation is accurately performed.

Fig. 11 is a cross-sectional view of the adjustment member 13, and fig. 12 is a bottom view of the adjustment member 13. Fig. 11 shows cam portions 13c formed by first to fifth cam portions 13c1 to 13c5 having different heights. As shown in fig. 11 and 12, a rotation preventing portion 13d functioning as a drop preventing plate is provided at a lower portion of the cam portion 13c.

After the adjustment member 13 is inserted into the adjustment member housing 12g provided in the case 12a in accordance with the rotational phase without being affected by the rotation preventing portion 13d, the adjustment member 13 is twisted to engage the fall-off preventing receiving portion 12f of the ridge inside the case 12a with the rotation preventing portion 13d into a male-female engagement as shown in fig. 8. In this way, the adjustment member 13 does not come off from the case 12 a. Further, since the click projection 19g is press-engaged with one of the first click recess 13d1 to the fifth click recess 13d5 of the rotation preventing portion 13d, looseness between the rotation preventing portion 13d and the fall-off preventing receiving portion 12f can be suppressed, and the adjustment member 13 can be accommodated in the adjustment member accommodation portion 12g provided in the case 12a without looseness. In fig. 12, a plurality of circular marks having different diameters are provided on the rotation operation portion 13a, and the marks are aligned with the click rotation position, so that the rotation adjustment by the adjustment member 13 can be smoothly performed based on the mark position.

By the above simple adjustment, the contact position or the interval between the movable contact portion 20a and the fixed contact portion 20b can be adjusted, and the natural rotation of the adjustment member 13 caused by the use of the complex operation switch a for a long time can be prevented.

By providing the adjustment member 13 on the case 12a of the micro-blade switch 12, the amount of pressing of the operation key 15 or the output relationship of the micro-blade switch 12 can be adjusted.

The miniature blade switch of the present invention can regulate the contact position or interval between the movable contact part of the movable contact piece and the fixed contact part of the fixed contact piece with the regulating member, and the miniature blade switch can be used in the assembly or after long term use and can perform ON and OFF operation stably.

Further, the composite operation switch of a video game machine, for example, using the micro blade switch having the above-described structure, can be adjusted in the operation position even after the micro blade switch is mounted on the operation panel, and can be provided to be finely adapted to the preference of the user or the habit of the operation.

Further, as in a general micro-blade switch, since the movable spring does not have a reverse operation (a snap action mechanism), it is possible to prevent the movable spring from generating a click contact sound at the time of reverse rotation, and further to prevent noise generation.
