Below each of the recognition shafts 32L, 32T, the bottom 24 of the housing 24 contains semi-cylindrical duct-like recesses 46L, 46T with the openings facing upwards (see Figure 1). 7 and 1 8) Each recess 46L, 46T accommodates a cylindrical body 48L, 48T formed by a torsion coil spring 50L, 50T made of a metal wire, and its axis is 52L, 52T. According to current technology, each The last turn of the spring 54] L, 54T is extended by a small section 56L, 56T in the axial direction of the extension axes 52L, 52T, which itself is extended by a free tail section 5 8L, 5 8T, which is a semicircle Shape, extending downwards in a vertical plane, in this way so as to be accommodated vertically—in complementary slots 62L, 62T, which are located at the bottom 24 of the housing, with the openings facing vertically upwards. Line segments 58L and 58D are placed on it In the related grooves 62L and 62T, the brackets P4L and P4T opposite to the leather line extend vertically downward. Spring 50L The first circle 64L, 64T of 50 0T is opposite to the last circle 54L, 54T on the axis, and extends upward through a vertical line segment 66L, 66τ, which is bent by 180. The upper line segments 68L ·, 68T are combined with the first circle To a vertically movable contact rod 70L, 70. Therefore, this end of each spring is constituted by combining line segments 66] L, 66D, contact rods 70L, 70T, and curved line segments 68L, 68T (which constitute the upper part of the contact rod (Last paragraph), it is placed in a vertical plane tangent to the cylinders 48L, 48τ of springs 50L, 50T. According to the current technology, the vertical direction of the contact rods 70L, 70T is at rest 13 200414060 at rest Position, this is due to the design of each spring 50L, 5〇τ and its contact rods 70L, 70T and its curved line segments 58L, 5 8T, and the latter is guided vertically into the grooves 62L, 62T, in this way At the angle of 50l, 50T of the fixed spring, the ends of the loops 54] L, 54τ are stopped in a rotating manner. The bottom 24 of the casing 22 is a hollow right-angled parallelepiped shape, and it is formed by the bottom 72 Defines a space with a horizontal upper surface 74. Each vertical contact rod The heights of 70L and 70T are the low contact sections 78] 1, 7 and 8T. The free ends 76L and 76T are extended to run above the part overlooking the upper surface 74. According to the current technology, each low contact section 78L and 78T will also Received by running sideways between two vertical bases 80L, 80T and 82L, 82T 'It belongs to the block of material 81L, 81T and 83L, 83T, it is integrally shaped with the bottom 72, and the opening faces vertically upwards . As a function of the ball 30 rolling, each of the control levers 70l and 70T can be tilted toward its vertical position, and the corresponding displacements are the low contact sections 78L and 78τ towards the bases 80L-82L and 80T-82T. In order to fix each identification axis 3 2L, 3 2T on rotation, the bottom 24 of the housing 22 includes a recess close to its horizontal upper surface 25, and its opening is vertical

Face up, 84L, 84T, 86L, 86T, which respectively accommodate the free ends 36L, 36T and 38L, 38T of the main body 34L, 34T of each identification axis 32L, 3 2T. The horizontal width of the recesses 84L, 84T is actually equal to the end. The diameter of the pivots 36L, 36T, and the recesses 86L, 86T with side openings towards the inside of the 14 414060. ^ Each—the recesses are shaped as hairpins 90L, 90T. The complementary recesses 88L and 88T ′ make the self-aligning I: and 92T of the elastic needle toward the inside of the housing, elastically urging the corresponding starvation, 38T ′ to push the roller by the starvation, 32% against the ball. The setting 20 also includes an access switch, which is actually an elastic trigger element of formula 94, which is a generally known design and is shaped like a star with four branches. ^ The trigger element 94 includes a central portion 96, which includes a disk, shaped as a round sphere 1 98, with its concave surface facing upward, and a track ball placed therein, and includes two pairs of radial branches 100L, 100T, Intersect into 90. Each of them terminates in a low bearing, and the contact edge is in the form of a circular arc lQ2L, ⑽ 丁, whose convex surface faces downward. The angular positioning of the triggering element 94 in the bottom 24 of the housing is determined by the recess 1G4T pair 'which accommodates two end edges ΐ () 2τ, and by a second recess 1044 which accommodates both ends One of the edges 101 and the other edge 102L is accommodated in the final recess 1041 (see FIG. 18) located in the cover. As shown in FIG. 17, the bottom 24 of the housing 22 is defined by two parallel and opposite left and right side walls 106L, and a lateral rear cross wall, while the front cross wall 106T includes its total height to the upper surface 74 and the bottom The distance of 72, and an opening, its function will be explained below. The lid 26 shown in FIG. 18 is composed of a horizontal plate, and its lower surface 27 is designed to support the upper surface 25 of the bottom 24. The bottom surface 27 contains a cylindrical arc-shaped depression so that the rollers, 15 42T, and pinions can move and roll freely. The lid 26 also contains a vertical partition "0" which is complementary to the opening 108 of the bottom 24, which extends along its vertical edge and contains two branches 2 which complement the grooves in the edge of the opening 108. In this way, So that the cover 26 can be slid onto the bottom vertically, in a sliding manner. In the combined position, as well as in the example shown in FIG. 23, the cover 26 thus completely closes the housing 22. The lightning bolt of the control device 20 Yi Yi a fan, ,, mouth straw by flat line or line 28 (also known as leather line)

And make sure that its design and technology are known. The south of the knife 11G is defined by its horizontal edge ⑴ vertically toward the base. This height is slightly smaller than the height of the opening 108 to allow the main body 29 of the leather line 28 to pass. In all the graphics except ® 9, there is no insulating upper layer on the upper surface of the leather wire, which is coated on the transmission rail that combines the bracket P1 and the terminal of the leather wire. This layer, ', or "surface layer" ensures that Electrical insulation becomes possible and reduces the risk of short circuits during skewed entry through the top 94. The leather wire 28 thus includes a main body, which is in the shape of a band 29, is thin and has a thickness of 0.12 mm, and is a conductive wire in it. The free end at the right of & 12 in Fig. 9 includes a series of conductive pads or frames Pi ' which are integrally made and connected to the line Fi, each of which constitutes a fixed contact ' and interacts with a variety of moving elements. The shape of the end section 120 is a regular dress shape, so that it can be placed in the bottom portion 24, and can be horizontally supported on the upper surface 74 of the bottom portion 72. In order to associate the access switch with the trigger element 94, the upper 16 200414060 surface 122 of the rear I 120 includes a central conductive bracket P1, which is an inserted type, which is connected to a line segment F1 and is located perpendicular to the central portion 98. The two brackets P2 are combined together and connected to a line segment F2, which are placed longitudinally on both sides of the central bracket P1, and each of them supports a low contact edge i02L of a trigger element 94. The conductive frame is also provided for transmitting identification signals generated by signal generators associated with the contact shafts 32l and 32T.

Therefore, according to the current technology, the main body of each spring 50L, 50D is connected to a line segment F4L, F4T through the brackets P4L, P4T, and the corresponding free ends 60L, 58L, 58T of the curved arms on it 60T is elastically supported. Therefore, each of the movable contact rods 70L and 70T is connected to the conductive frames P4L and p4T and the corresponding line segments F4L and F4T by springs 50L and 50D.

Each of the movable contact rods 70L, 70T has a low contact section 78L, and a tin is accommodated between two opposite contact frames P5L and P5T and a vertical p6L and M. The two are cut out by the section 120 of the leather line 28 The part is made, and after being fixed, it stands upright on a vertical plane and is supported on the vertical surfaces corresponding to the bases 80L, 80τ, 82L, 82T. By placing the section 120 of the leather wire 28 on 74 of the bottom 24 of the housing 22, various fixed contacts constituting the contact bracket ρ! Are made, and a part of the leather wires 28, 29 is separated from the opening 108 , Clamped by its low edge. " 1 The operation of the signal generator according to the current technology will be described below. This description will refer to the identification shaft 32. The other shafts operate similarly because all their components are the same. Except for the spring 50 d, it is symmetrical to the vertical plane S-S due to the load balance. In the rest position of Figs. 4 to 6, the movable contact lever 70L is vertical and its curved upper section 68L is received, running sideways in the direction of D, and on the opposite sides of the two consecutive teeth of the identifying pinion 44L. Between sides 45L. By causing the ball 30 to roll around its center C, and about the horizontal axis in the longitudinal direction, the roll of the shaft 32L results from its rolling around its rolling axis 40 £. This rolling causes contact of the side 45L of the right-hand tooth, which then pushes the upper section 68L laterally from the right to the left. _ With the possibility of elastic deformation of the main body 48L of the spring 50L, the lever ^ 〇L is connected to this spring and acts as a return spring for returning the lever 7 to its rest position, which is completely inclined relative to 卩 52L Until its low contact section 78L #stent P5L is electrically pulled and in contact with the contact surface 80L on the skin line, an electrical connection is established between the hidden price of the bracket.

The rotation of the roller 32L in the direction of the clock continues, and this rotation causes the "Maltese cross," a type of mechanical placement, to automatically jump off the upper 68L, which continues its tilting movement, and will eventually come in contact with only 70L. It will automatically return to its stable vertical rest position together. Conversely, the rolling movement of the contact rod ° fruit ball 30 will continue in the same direction, and the rod 70 will again tilt in the same direction, as shown in "7B. Once again, the electrical contact established between P5L @ P4L generates a new signal. If the ball 30 is driven to roll in other directions, and the tooth 4 is tilted by 70 ° until its low contact section 78 contacts the conductive frame 18 200414060 P6L and Contact the vertical surface 82l. This will cause contact, and then establish electrical contact between the brackets P6L and P4L, which will generate a signal that is different from the signal generated by the impulse 50L connecting the brackets P5L and p4L. In P4L · The difference between the two signals established with P5l or PZ and P 幵> is that it can identify the rolling direction of the relevant recognition axis, followed by the rolling direction of the ball. This is by each signal The raw Crying opposite said seat Ga Λ shame of a movable contact of the early or 70L 70Τ.

Of course, depending on the type of operation applied to the ball by the user, the latter can cause the two recognition axes 32L and 32T to roll simultaneously in one or the other of their opposite directions. This ball actually always rotates around a horizontal axis, as the ball rolls on the plane: the number of pulses generated by the generators is individually proportional to the χ and γ elements of the cursor survey on the screen. 30 The driving of the rollers supported by the shafts 32L and 32T is ensured by the friction of the outer surface.

And 90Τ-92Τ vertical force F

Both the shaft and the roller are supported against the ball by the pin springs 90L-92L. The entrance is affected by applying a trackball 30-1 with a direction V level. 7 # 有 k 成 其 的 为 外部 2 的 效应 的 影响 ， 造成 定 和 定 对… The state of the contact element 94 which is vertically downward, and the eight central parts 98 contact the conductive frame p P2 ^ pla ^ ^ As a result, the electrical connection between the bracket P1, followed by the connection between the bereavement slaves F1 and F2, 19 200414060 provides the user with the tactile sensation of entering the switch. Since the center of the positioning ball 30 is below the axis and 40T plane, the entry motion is easy to separate the ball 3G from the roller and 42T, and this has no adverse effect on the rollers 42L and 42T and thus the identification signal generator. , It is maintained in a state corresponding to its position when entering. The various steps of the combined device element can be seen continuously in Figures 3 and 10 to 16 before the cover is closed. The position of the segment 120 of the leather line 28 in the bottom 72, 74 of the bottom 24 of the housing 22 is ensured through the four edges of the element 94], and the contact pressure of ⑷τ is ensured, and according to the current technology, it is a spring 50L # 口50T

Line segments 58L and 5 8T 14 8 grip the surface area of the leather thread in the heated coil screw 1 $ 2 ′. In addition, the lower surface of the center leg 149 of the cover 26 is used to fix the cover 26 to the part 24. This clamp is combined by the low edge of the cover's partition 110, which can be: complementary shapes and ordinary shapes (not shown), such as in The edges " 1 and / or are on the surface of the outsole p. Raised and / or complementary depressions formed in niches.

Aspects of the present invention will be described below, particularly in comparison with the prior art. In general, each spring 50, 50T is simplified by removing the free end sections 58L, 58T in the shape of a loop, which was previously used to stop the rolling and position the angular positions of the movable contact rods 70L, 70τ, and Used as a power connection for springs. The lower part 24 is also simplified to the same extent. According to the present invention, in order to provide the above-mentioned function of 20 200414060 by the loops 58L ·, 58T, the second shaft ends of the springs 50L and 50T include the last _loop-5 4 T The loops are fixed, and the relevant loops are placed in the relative positions of the surface portions 47L, 47T of the ducts 46L, 46T facing the deer. For example, you can hot-melt the 8 or 9 end turns of the spring on the right in Figure 16. The hot refining operation in Fig. 8 is to heat the corresponding elastic yellow section by the Joule effect, which is performed by two electrodes E1 and E2, which are applied to the corresponding last circle of the section fixed by hot melt. Passing a current through the coil between the electrodes E1 and E2 will cause the Joule effect to immediately cause the temperature of the corresponding aged metal segment of the spring constituting the coil to increase immediately. The two private poles E1 and E2 further exert a vertical downward force on a section of the spring. The temperature increase obtained by the Joule effect then causes the local dazzling of the concave surfaces 4 7 L, 4 7 T of the ducts 46l, 46τ. In addition, an "attractive" and / or capillary phenomenon occurs, whereby the mold surfaces of the concave surfaces 47L, 47T of the plastic conduits 46L, 46T abut against the entire outer circumferential surface of the heated ring group. Still placed between the heating rings. After stopping the passage of the current, the temperature will drop rapidly, and the previously melted and melted plastic will condense and be close to the circle group. At this time, there will be a better occupant force. The strength of the current and the elapsed time are selected as a function of the ohmic impedance of the line. The leaflet is made of a far line and is the melting temperature of the plastic at the bottom 24 of the case. 21 200414060 By way of example, the values of intensity and heating time between 1A and 2 A are several tenths of a second. Due to the elastic deformation characteristics of the loops, each plane is substantially perpendicular to the axes 52L, 52T of the main bodies 48L, 48D, and the application of the electrodes can produce slight deformations of the loops, turning them into oval shapes. This deformation is beneficial because it will increase the corresponding portion of the permeation loop to the localized refining concave surfaces 47L, 47T of the catheter. In order to provide the electrical connection of the main bodies 48L, 48D of the springs 50L and 50T, the leather wire 29 includes a conductive bracket p4L, p4T, which is perpendicular to the plane of the bottom of the bottom position 24, and can be placed relative to the bottom position 24. The raised surfaces 130L, 130T are placed on the horizontal surface of the concave bottom of the duct and below the hot-melt circle group. During the hot-melt operation, the conductive brackets P4L, P4τ are applied to the opposite parts around the circle by the pressure applied vertically downward by the two electrodes E1 and E2. Due to the elastic characteristics of the circle in the vertical plane perpendicular to the axes 52L, 52T The pressure of the upper circle of the conductive support P4L, P4T, itself rests on · 2 UGL, 13GT, and continues to be maintained after the end of the hot material industry, that is, when the electrode no longer exerts any pressure on the spring. In order to ensure the correct positioning of the bracket P4 " σ P4T in the corresponding circle group to be hot-melted, the leather wire will include a positioning hole into which bolts u2L, 132T are inserted, and are integrally molded with the bottom 24 of the casing. The bolts U2L, 132T can also be flexed by heat, so as to further improve the fixing of the end position of the leather wire 29, which constitutes a bracket Chen, ... 22 200414060 The number of hot-melt loops depends on the value of the stiffness of the spring torsion pair that provides the function of returning the movable contact frame 70L, 70T to its vertical rest position, and the desire to maintain and fix the elastic spring 50L, The strength of the hot melt section of 50 τ. The vertical angle direction of the movable contact frames 70L and 70τ of the spring is obtained by a shelf which is not shown in the figure, and belongs to a hot melt operation tool.

Each: The duct-like concave surfaces 46L, 46T are designed to avoid any radial clamping of the loop corresponding to the spring η, so there is no risk of torque generated in the loop during the placement and fixing operation of the spring by hot melting. "

Therefore, after the work is performed by the fixed spring, there is no risk of false angular displacement of the movable loop constituting the movable contact frame when the bracket is removed. Based on the design of the current technology shown in Figures 23 and 24, establishing direct electrical contact between the movable stent muscles on the fixed conductive racks P5L, P5T and P6L, P6T, and the bottom ends 76L, 76T will induce specific Pressure to ensure good power efficiency, and reduce excessive variation in the fixed force 'loops 68L, 68T to use this force to embed the pinion 4 etiquette and surgery. In particular, it is necessary to break the high precision of the brackets 70L and 70T in length and the perfect burr-free separation of the low free ends 76L and 76T. In addition, 'repeat hundreds to thousands of times to establish the electrical connection between the low-end separating edge and the conductive shelf' may cause premature aging of the precious metal layer covering the latter portion. In order to improve these shortcomings, the present invention proposes a new design which aims to produce a fixed electrical contact capable of elastic deformation. 23 200414060

, ‘Purpose, the lower sections 78L, 78T of the movable contact frame 70L, 70T are housed between two parallel and relatively fixed horizontal contact rods, 34T. / 、 The two fixed contact frames of the one contact pair related to 70L · or 70T are completely the same. Therefore, the present invention requires four identical stents. As shown in FIG. 20, each of the fixed contact rods 13 and 134 is made of a bent metal wire, and is mainly composed of straight bodies 138L and 138T, which terminate at a shaft end at a free end contact section i4. L, ΐ4〇τ, and at _: the other ends at a hairpin loop 142L ·, 142T, which is placed on a vertical plane in which it is elastically deformable. The main bodies 138L, 138T and the loops 142L, 142T are accommodated in the corresponding vertical grooves 144 and 144T of the bottom 240 of the housing 22, and are arranged on a vertical plane parallel to the axis of the corresponding contact spring. Therefore, each of the fixed contact rods 134L ·, 134T is built-in to the bracket, except for its free end contact sections 14L, 14〇τ, each of which is freely arranged on the vertically movable contact rod 70L, 7〇τ on both sides. Xin Each free end segment 140B, 140T can thus be freely deformed laterally on a horizontal surface, while a fixed contact pair opposite pole is placed in the same horizontal plane. Each of the vertical loops 142L, 142T is configured with a related fixed conductive frame in the bottom 74 relative to the low part 24, and provides a power connection of the fixed contact rod 1 3, 134T ', which is a conductive frame pair p5L_ which belongs to the end of the leather wire 28. P6L or P5T-P6T. 24 200414060 Relative to fΓ, a fixed contact frame 134L, 134T is fixed to the housing. = Straight grooves 144L, ..., which can be used in the side clamps between the grooves and are accommodated in this groove. In the same way, the fixation of each coil of the spring and each fixed contact rod can be improved by the local heating of the straight body 138L and 138 T with the help of two electrodes. In the same method, a second force is applied to the spring 'by the electrode during the current passing, and then a beautiful force is applied to the relevant loop i42l, which is maintained by the solid conductive conductor, which is maintained after the electrode is applied. Between the 78L and the low sections of the movable contact frame 70L and 70T, and one of the two 140L and 140T Φ 140T sections, the electrical contact established corresponds to the cylindrical surface and the positive axis. Intermediate contact, also known as intersecting rolling contact, is the best form of semi-permanent electrical contact. In addition, each of the free end sections 14L, 140τ exhibits the ability of elastic deformation ', and its accompanying, free end sections 78L, 78D. This accompanying phenomenon makes it possible to absorb the size variation of any identification axis, thereby reducing the large variation of the sweet pinch force. In addition, it suppresses mechanical shocks between the segments 78L, 78D and the segments 140L, MOT. 〇 In the case of fast rolling of the ball, the period between two impacts can be less than 2ms, and the risk of false rebound is thus reduced. In addition, the self-cleaning effect between the contact points is achieved by the accompanying elastic deformation. Movable and fixed contact frames can be made of stainless steel or metal wires previously plated with gold or silver plated 25 ^ 00414060 steel alloy. Electric contact no longer depends on the movable contact frame 胤, 70 τ degrees, nor does it depend on the split quality of its free ends 78L, 78T. Changxin ’s fixed contact volume is specifically solved by the current technology. This has significantly increased the total number of coils per spring, and = the number of loops, 68T embedded in the pinion, and in the field during the operation. cut back. T Kosi ratio of diameter without correction between friction 42T and ball 30 surface

In view of this, it is possible to reduce the force of the mother-rollers 42l, 42T and to reduce the possible risk of sliding on each of the elastic rollers 42L. According to the current technology, for example, the diameter of each roller is reduced by 1/3. This reduction makes it possible to increase the value of each rolling pulse of the ball by a ratio of 3/2. Say

This makes it possible to reduce the deviation of the ball from the center of the upper surface of the device. The total height of the theta shell is reduced without changing the total height of the device, that is, the height between the low surface of the outer stage bottom 24 and the top of the trackball 30. Therefore, it is possible to increase the height of the portion of the ball exposed outside the upper surface i 4 4 of the housing 2 2, so that it is possible to mount the device on a larger housing surface. According to a variant (not shown), by providing two intermediate contact frames with slightly different heights, 'place one on top of the other in the same slot, it abuts on a separate and separate conductive frame, multiplying by objective. It is also possible to identify the number of fixed contacts of the spring. 4 kinds of solutions make the output of the synchronous signal device can be independently doubled. Finally, the reduction of the ball deviation makes the internal components of the device better.-Chiyo Batu light-emitting diodes 150L ·, 150T, can be better placed near each other, when two adjacent diodes Start synchronously to get the first color day $ for better color mixing. The embodiment presented in FIGS. 21 and 22 includes a housing bottom 24 that surrounds the base

㈤ & mouth 疋 is molded around the contact point, which is extended by the connecting piece or output, which is a coplanar sheet protruding laterally and evenly distributed on the two opposite sides of the shell from the outer ridge. The terminal of the leather wire 28 is coupled to the fixed contact point pi, and is arranged on the bottom 72, 74 by the wire Fi embedded in the bottom insulating molding material. The 4L and P4T power connection "grid" curved bracket, which replaces the skin as disclosed and presented in WO-A-〇2 / 〇75641, contact springs and brackets, 5GT_7GL, surgery can be used-completely symmetrical A single element is implemented 'and it can be used as an axial or lateral 5ql, t58l, T_68L, T-70L, T. Depending on the size of the shell, the general length of the 5 single rack elements is somewhat important. When the ratio of the length and diameter of the wire is greater than 75%, it is possible to replace the torsion coil springs 50L and 50T by a torsion bar spring. For example, a torsion spring fixed by a wire and its outer diameter is equal to the diameter of the wire . The elastic power and torque caused by the interaction between the loops 68L and 68T and the related pinion gears and operations are sufficiently lower than the driving power or torque of the track ball on the rollers 42l and C. 27 200414060 The accommodating part of the spring and the corresponding bottom is greatly simplified, and its overall length is reduced, as shown in Figures 23 to 29. In this case, a complementary concave surface that is tempered to the housing is the corresponding section of the second shaft end of the torsion bar spring. According to other solutions, such a wire or rod spring may be a torsion or testament spring (for example, in the French patent application No. · · · · · · 39706970, it is assigned to the name of the applicant on June 11, 2003) , Especially when the guide length of the rods is very short and close to the swing or tilt loops 68L, 68T.
