Shown in Fig. 5 (a), also the end face 4b-1 of the recess 4b of the leading section of fastening pawl 3b and control member 4 can be made tabular surface and come butt, but in this case, be to stop the recovery of fastening pawl 3b with the frictional force of snap-latch surface, thereby the temporary fixed of control member 4 is in an unsure state.Therefore, shown in Fig. 5 (b),, adopt to make snap-latch surface have the structure that inclination makes the leading section of fastening pawl 3b engage with the end face 4b-1 of recess 4b as preferably.In addition, shown in Fig. 5 (c), if the leading section of fastening pawl 3b and the snap-latch surface of recess 4b are set as curved surface, then when fastening pawl 3b restores, the situation of the temporary fixed state that can not remove control member 4 can not appear interfering because of the end face 4b-1 of the leading section of this fastening pawl 3b and recess 4b, in addition, also can not produce control member 4 blocks when sliding and hinders such problem of sliding.
As mentioned above, when control member 4 is temporarily fixed on the position (position of the ON/OFF signal of switch in magnetic force detecting sensor 12 (flux reversal described later position)) of regulation with respect to keeper 3, shown in Fig. 4 (c), make in the end that is formed at keeper 3 3d of negative thread portion in week and assisted group in advance that circuit substrate 9 is housed, the pin thread 5a of the terminal substrate 5 of magnetic force detecting sensor 12 grades screws togather, for example if the keeper 3 that assisted group is installed rotates with respect to terminal substrate 5, then both axial relative positions can change, thereby can inching be disposed at the magnet 7 and the relative position that is disposed at the magnetic force detecting sensor 12 of terminal substrate 5 that is held the temporary fixed control member 4 of part 3.Promptly, the 3d of negative thread portion that is formed at keeper 3 screws togather each other with the outer screw section 5a that is formed at terminal substrate 5 and constitutes the adjustment part, position, utilize this adjustment part, position to come the relative position of inching magnet 7 and magnetic force detecting sensor 12, thereby can absorb the error of the aftermentioned flux reversal position that the deviation because of magnetic field intensity produces.
Particularly, magnetic force detecting sensor 12 is connected to not shown lamp, confirm bright lamp/turn off the light (output of the ON/OFF signal of magnetic force detecting sensor 12) of this lamp on one side, make keeper come the relative position of inching magnet 7 and magnetic force detecting sensor 12 on one side with control member 4 rotations, become moment of the distance of switching the ON/OFF signal in the distance L between the two shown in Fig. 4 (c), stop the rotation of keeper 3 and control member 4.
As implied above, coming have the keeper 3 of control member 4 and assisted group in advance that circuit substrate 9 is housed in conjunction with temporary fixed by auxiliary assembling, the terminal substrate 5 of magnetic force detecting sensor 12 grades, and when the relative position of the magnet 7 that is disposed at above-mentioned each member and magnetic force detecting sensor 12 carried out inching, shown in Fig. 4 (d), if above-mentioned integral body is inserted in the switch housing 2 as a unit, and the fastening projection 3c of the upper and lower surface that is formed at keeper 3 is engaged with the connecting hole 2a of the upper and lower surface that is formed at switch housing 2, then can be with in the cell location and the switch housing 2 of packing into.Like this, owing to the 3B of rotation stopping portion, the 5A (with reference to Fig. 2 and Fig. 3) of the rectangular flange shape that is formed at keeper 3 and terminal substrate 5 respectively are chimeric with the shell main body 2A inside of the square tube shape of switch housing 2, therefore, keeper 3 be can stop, the control member 4 and the rotation of terminal substrate 5 in switch housing 2 of keeper 3 are temporarily fixed on, thus can fixed magnet 7 and the relative position of magnetic force detecting sensor 12.
In addition, last shown in Fig. 4 (e), at the active force that overcomes spring 6 towards the rear during pressing operation member 4, the end face 4b-1 of recess 4b that is formed at the piston portion 4A of control member 4 breaks away from the fastening pawl 3b of keeper 3 and removes both engagings, fastening pawl 3b is because elasticity expands the original state that resets into of opening towards radial outside (the diagram direction of arrow), thereby removes temporary fixed with respect to keeper 3 of control member 4.Like this, allow the slip of control member 4, when hand is left control member 4, this control member 4 is because of active force (the diagram direction of arrow) slip towards the place ahead of spring 6, under the state of the inner face butt of the shell main body 2A of the projection 4c of the end face that is formed at piston portion 4A and switch housing 2, control member 4 is static, and at this moment, the axle 4B of this control member 4 is from the only outstanding ormal weight of switch housing 2.
According to above explanation to get assembling noncontacting switch 1, this noncontacting switch 1 is applied to purposes as the stop lamp of vehicle.
(action of noncontacting switch)
Then, the action of the noncontacting switch 1 that the stop lamp as vehicle is used according to Fig. 6 (a)～Fig. 6 (c) and Fig. 7 (a)～Fig. 7 (c) and detect principle and describe.Fig. 6 (a)～Fig. 6 (c) is the sectional view of the action of explanation noncontacting switch, and Fig. 7 (a)～Fig. 7 (c) is the figure of expression magnet corresponding with the state shown in Fig. 6 (a)～Fig. 6 (c) and the position relation of magnetic field detection sensor in magnetic field.
Pass the support 15 of the word of the falling L shape that is installed on car body by the car body installation portion 2B that makes switch housing 2, and screw the nut 16 that the outer screw section 2b (with reference to Fig. 2 and Fig. 3) with car body installation portion 2B screws togather, noncontacting switch 1 is installed on car body 17 via support 15, and is disposed at the rear of brake lever 18.
And, do not depress the driver under the state (non-on-position) of not shown brake pedal of lower end of brake lever 18, shown in Fig. 6 (a), the axle 4B butt of brake lever 18 and noncontacting switch 1, thus this 4B is pressed in the keeper 3.Under this state, the magnet 7 that is disposed at control member 4 is positioned at and magnetic force detecting sensor 12 immediate positions, magnetic force detecting sensor 12 is positioned at the stable magnetic field range of magnetic field intensity of magnet 7, becomes the ON state owing to detecting many magnetic lines of force of being sidelong out up in Fig. 7.In addition, in the present embodiment, adopt under the ON state, therefore the structure of magnetic force detecting sensor 12 output OFF signals, turns off the light not shown stop lamp.
Yet magnetic force detecting sensor 12 is that quantity, the direction with the magnetic line of force waits the power of judging magnetic field, the member of magnetic pole, but has represented the intensity in the magnetic field that the magnet 7 by employed ring-type in the present embodiment forms and the direction of the magnetic line of force in Fig. 7.Because the magnet 7 of this ring-type is formed with two magnetic fields around the axle center of control member 4, the intensity in this magnetic field with the nearer regional A of magnet 7 in stronger, two magnetic field cancels each other out and, represents median in the area B of this centre in zone C far away.In addition, use arrow to represent the direction of the magnetic line of force.In the present embodiment, in Fig. 7, the downside of magnet 7 is the N utmost point, and upside is the S utmost point.Therefore and since the magnetic line of force from the N utmost point towards the S utmost point, so with the overlapping center line in two magnetic fields of the nearer regional A of magnet 7 on, shown in Fig. 7 (a), because many magnetic lines of force towards upside (from the N utmost point to the S utmost point) are concentrated, and therefore, are formed with stable field region.On the other hand, in magnet 7 zone C far away, even the magnetic line of force also disperses on the overlapping center line in two magnetic fields of magnet 7, the direction that forms the magnetic line of force can not become the unsettled field region of certain direction, shown in dotted line a, also there is the flux reversal position of the direction upset of the magnetic line of force.
Shown in Fig. 6 (a), do not depress the driver under the state (non-on-position) of not shown brake pedal of lower end of brake lever 18, axle 4B remains in bulged-in service position, shown in Fig. 7 (a), magnet 7 is positioned at and magnetic force detecting sensor 12 immediate positions, this moment as mentioned above, the field region of the magnetic field intensity that magnetic force detecting sensor 12 is positioned at magnet 7 stable (many magnetic lines of force towards upside (from the N utmost point to the S utmost point) are concentrated the state that exists), therefore, the magnetic line of force of in Fig. 6, being sidelong out can be detected reliably up, thereby the ON state can be kept.In addition, in the present embodiment,, therefore, can keep the state of turning off the light of not shown stop lamp reliably because magnetic force detecting sensor 12 adopts the structure of output OFF signal under the ON state.
When car brakeing, when the driver uses foot-operated brake pedal down, brake lever 18 is that the center is when rotating with the not shown rotating fulcrum on its top, in noncontacting switch 1, by axle 4B and brake lever 18 butts of spring 6, and, give prominence to gradually from switch housing 2 along with the action of this brake lever 18 towards the place ahead application of force, accompany with it, control member 4 slides towards the place ahead with the magnet 7 that is disposed at control member 4.In addition, in this process, when magnet 7 arrives position (only leaving the position of the distance L shown in Fig. 4 (c)) shown in Fig. 6 (b) and Fig. 7 (b) with respect to magnetic force detecting sensor 12, shown in Fig. 7 (b), magnetic force detecting sensor 12 is arranged in the flux reversal position in magnetic field of magnet 7, and (line that is represented by dotted lines a).Under this state, because the direction of the magnetic line of force is overturn 180 °, therefore, magnetic force detecting sensor 12 can not detect the magnetic line of force that the upside from magnet 7 towards Fig. 7 is emitted, and this magnetic force detecting sensor 12 becomes the OFF state from the ON state.In addition, in the present embodiment, because magnetic force detecting sensor 12 adopts the structure of output ON signal under the OFF state, therefore, output signal switches to the ON signal from the OFF signal, thereby makes the bright lamp of not shown stop lamp.
In addition, when the driver further depresses brake pedal from the state shown in Fig. 6 (b), shown in Fig. 6 (c), braking vane 18 is away from the axle 4B of noncontacting switch 1, control member 4 stops at illustrated off-position (on-position) owing to the projection 4c of the end that is formed at its piston portion 4A and the inner face butt of switch housing 2, thereby a 4B is maintained from the outstanding state of switch housing 2.Under this state, shown in Fig. 7 (c), (dotted line a) is positioned at the zone C of the direction upset of the magnetic line of force owing to magnetic force detecting sensor 12 is crossed the flux reversal position in the magnetic field of magnet 7, therefore, in Fig. 7, there is not the magnetic line of force of being sidelong out up, thereby makes magnetic force detecting sensor 12 maintain the OFF state reliably from magnet 7.In addition, continue output ON signal as output signal, so, can make stop lamp maintain the state of bright lamp.Promptly, if with the state shown in Fig. 6 (b) and Fig. 7 (b) is that boundary further depresses brake pedal, then stop lamp can continue bright lamp, by pin being lifted away from from the state (on-position) that depresses brake pedal, turn back in the process of the original operating state shown in Fig. 6 (a) (non-on-position) in brake lever 18, after this braking vane 18 is by the position shown in Fig. 6 (b) and Fig. 7 (b), magnetic force detecting sensor 12 becomes the ON state, the output signal of magnetic force detecting sensor 12 switches to the OFF signal from the ON signal, thereby stop lamp is turned off the light.
