Fig. 9 is the stereoscopic figure of dome-shaped switch, Figure 10 is the plane graph of console switch, Figure 11 be the expression console switch internal structure Figure 10 the A-A line to pseudosection, Figure 12 is the expression fixed contact of flexible substrate and the stereogram of contact corresponding states, and Figure 13 is the expression key diagram of the corresponding states of the fixed contact of contact and flexible substrate down.
Below above-mentioned support 19, separate by down stroke space 19B (with reference to Figure 11) being provided with dome-shaped switch 58 (with reference to Fig. 9).This support 19 and dome-shaped switch 58 by down stroke space 19B around possess dust cap 22, with the outside blocking and seal, and dust cap 22 formed the broken end cone shape by the synthetic resin material around dust cap 22 will this space 19B.
Above-mentioned dome-shaped switch 58 is with sheet material 23, push-button switch 24, flexible substrate 25 structure by the integrated formation of this sequential cascade, and the flexible substrate 25 of lower floor is pasted on the upper surface of matrix 26, thus, is equipped with dome-shaped switch 58 at the upper surface of matrix 26.
And, amount to five contacts with the peripheral fixed contacts 60 of a central fixed contact 59 and four and be equipped with push-button switch 24 accordingly, with sheet material 23 coverings above it and be pasted on the assigned position of flexible substrate 25 in push-button switch 24 motionless modes.Thus, constitute the center switch S1 that is provided with press corresponding depressed position of casting die 21 and with press respectively corresponding depressed position of rotary manipulation body 14 four peripheral switch S2 of setting.
In addition, at the outer circumferential side of this matrix 26, erect the lifting prerotation vane 67 of being equipped with contrary concave shape from the bottom surface at its four positions.This lifting prerotation vane 67 with retention tab 49 engagings of above-mentioned above-mentioned support 19, liftably is provided with and presses haul distance in contrary spill.On the lifting prerotation vane 67 at these four positions,, remain in rotary manipulation body 14 and permission inclination corresponding when pressing of the topmost of support 19 with its direction by the retention tab 49 that is stuck maintenance respectively.Therefore, rotary manipulation body 14 is operated certain path increment of pressing under the state that tilts a little.
The action of the console switch 11 that constitutes so then, is described.
At the be pressed state of standby of this console switch 11, as shown in figure 11, five push-button switches 24 that dome-shaped switch 58 is possessed have semicircular cheese, and high portion is relative with the lower end of respectively pressing lower process 50,57 in the push-button switch 24.These push-button switches 24 with from the top carry out strain at above-below direction accordingly by exerting oneself, accepting depression when exerting oneself, resetting when exerting oneself to unclamp, when returning to original height and position, become cheese, and prepare pressing next time.In addition, because the fixed contact of the flexible substrate 25 corresponding with push-button switch 24 is not pressed, therefore, output detection signal not when non-conduction.
Under casting die 21 is pressed the situation of operating, accepting should be by exerting oneself, and casting die 21 descends and press down stroke, pushes central push-button switch 24, this push-button switch 24 with its press direction central fixed contact 59 planes contact and make it conducting, will be from the signal output of central fixed contact 59.And, unclamp casting die 21 when exerting oneself, push-button switch 24 elastic resets via by lower process 57 casting die 21 upwards being pushed away, return original position.
In addition, under rotary manipulation body 14 is pressed the situation of operating, accept by exerting oneself at the ad-hoc location of its push.At this moment, rotary manipulation body 14 is via pushing the push-button switch corresponding with ad-hoc location 24 by lower process 50, this push-button switch 24 with its press direction peripheral fixed contact 60 planes contact and make it conducting, will be from the signal output of this periphery fixed contact 60.Afterwards, unclamp rotary manipulation body 14 when exerting oneself, push-button switch 24 elastic resets are via by lower process 50 support 19 upwards being pushed away.Thus, rotary manipulation body 14 returns the origin-location.
In addition, under rotary manipulation body 14 and support 19 move up situation about resetting, flow into extraneous gas between dome-shaped switch 58 downwards and the support 19, still, even at this moment dust is invaded, owing to possess dust cap 22, so also can interdict the intrusion of dust.Thus, can keep the contact structure that the intrusion of having eliminated dust causes the excellence of deterioration.
In addition, under the situation of rotary manipulation rotary manipulation body 14, as shown in Figure 5, the encoder that is assembled into this rotary manipulation body 14 uses moving contact plate 15 to equidirectional rotation, as shown in Figure 6, irrotational upward contact 16a, 17a, the 18a that are fixed in support 19 contact with the face that slips 40 of this encoder with moving contact plate 15, and detect the phase signal as rotary encoder.In addition, this slips face 40 and is formed at same plane, therefore, guarantees to go up contact 16a, 17a, 18a with respect to the stable contact that slips face 40.
On the other hand, shown in Figure 12 (A), with respect to the flexible substrate 25 that possesses common fixed contact 61, first fixed contact 62 and second fixed contact 63, shown in Figure 12 (B), following contact 16b, 17b, 18b remain state of contact by non-rotating keeping.Thus, can detect position, the direction of rotation of rotary manipulation body 14 rotary manipulations, the signal of rotary speed by the signal that obtains from last contact 16a, 17a, 18a.In addition, when rotary manipulation body 14 rotary manipulations, the spheroid 54 that is located at the two ends of the helical spring 54 of setting on the casting die 21 is corresponding with the male and fomale(M﹠F) 35 of the rotary manipulation thoughts and feelings usefulness of casting die inserting hole 27, apply certain active force and produce rotational resistance with respect to rotary manipulation body 14, therefore, with rotary manipulation body 14 every rotation 30 Du Shikede click feel, the information of rotary manipulation passes to operator's hand significantly.In addition at this moment, the rotary manipulation of the above-mentioned thoughts and feelings K of mechanism thoughts and feelings part is separated with contact part, and therefore, consumption powder each other can not produce baneful influence to contact part.
Like this, when constituting multi-direction push-in console switch, for the encoder with the upper strata is separated into the three-decker of above-below direction with each conducting strip 16,17,18 in moving contact plate 15, middle level, the flexible substrate 25 of lower floor.In addition, shown in Figure 13 (A), following contact 16b, 17b, 18b are non-rotating, and the contact that encoder is used on the flexible substrate 25 of lower floor is removed to the upper strata, therefore, lower floor's plane domain in broadness can disperse to be provided with fixed contact largo, and the correspondence of this fixed contact is become easy.Therefore, shown in Figure 13 (B), free end side at following contact 16b, 17b, 18b is extended the elastic reaction of the contact of the elastic reaction of the contact of length by being divided into, and obtains stable elastic reaction, thereby contact is stably contacted with fixed contact.
In addition, each conducting strip that constitutes the middle level 16,17,18 o'clock, the fixed space of space in above-mentioned enclosure space 19A above for not changing by push from corresponding upper strata to the middle level, above-mentioned by down stroke space 19B in the variable spaces that all changes for push each time of following side space from corresponding middle level to lower floor.Therefore, under rotary manipulation body 14 was pressed the situation of operating, only the following contact 16b that extends to lower region, 17b, 18b were to carry out strain to the mode of pressing the direction compression.On the other hand, the last contact 16a, 17a, the 18a that extend to top area are not compressed by push power, therefore, are not subjected to external force.Therefore, the last contact 16a, 17a, the 18a that extend to top area do not apply the external force of pressing direction, and therefore, it is little to load, and the stress design of the spring of conducting strip becomes easily, and durability improves.
In addition, can constitute and be dispersed in the contact structure that it presses the upper and lower of direction with the overlapping depressed position of four direction of rotary manipulation body 14.Therefore,,, therefore, can dispose fixed contact 61,62,63 and conducting strip 16,17,18 at discoid outer circumferential side, and follow, long conducting strip can be set in this because the configuration degree of freedom of fixed contact improves at configuring area.Consequently, except can guaranteeing big contact travel, also have and to suppress to assemble deviation and cause the effect that influences.
In addition; think that the external diameter of console switch 11 is more little; the configuration pattern of contact also must be more little; because of the stickup deviation of flexible substrate 25, configuration pattern deviation etc. causes the influence of output signal is become big; but; owing on irrotational support 19, be fixed with conducting strip 16,17,18; therefore; the fixed contact of these irrotational conducting strips 16,17,18 and irrotational flexible substrate 25 is non-rotating; therefore; contact performance improves, and produces the key element that contacts deviation with fixed contact 61,62,63 and tails off, and obtains stable output signal usually.
Figure 14 represents other examples of casting die 21, and this casting die 21 is to be provided with spring base 141 and to constitute inserting to be situated between between the helical spring 54 lead to cross-drilled hole 53 and the spheroid 55.This spring base 141 has the mode of circular shape and face contact with the sphere along spheroid 55 and constitutes, and contacts with the line that does not have spring base and compares, and the effect of helical spring 54 is pressed to spheroid 55 and stably transmitted.
