Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a pull switch applied to lighting equipment and the like.

[Background technology]

For example, the conventional pull switch was developed in 1983.
As in No. 128326, a wheel metal fitting, a handle with a handle metal fitting and a coil spring are fitted to the mandrel, and the coil spring biases the handle to return, and the wheel metal fitting is attached to the mandrel through the handle and handle metal fitting. It comes into elastic contact with the fixed contact of the base that is fixed to the base. Pulling a pull member connected to the handle rotates the handle and slides the gear fitting over the fixed contact. When you release the pull member,
The handle returns to its original position due to the coil spring, but
The gear metal fittings do not rotate because they are locked to the taper of the fixed contact. The rotation range of the handle is determined by locking a stopper portion integrally formed on the handle with the switch case.

However, since the stopper part is formed on the handle, the switch case becomes larger, and since the stopper part requires strength, the thickness of the handle needs to be increased. Also, attach the stem with the handle etc. installed to the switch stand,
Assembly was complicated because it was necessary to attach the handle to the stopper of the switch base while applying a spring force to hook the handle to a support fitting provided on the mandrel.

[Effect of idea]

The purpose of this invention is to provide a pull switch that can easily regulate the operating range of the handle without increasing the size of the switch case or the thickness of the handle, and that is easy to assemble. be.

[Disclosure of invention]

In this invention, a wheel metal fitting, a handle with a handle metal fitting, and a coil spring are provided on the mandrel, and the coil spring presses the wheel metal fitting against a fixed contact, urges the handle to return, and rotates the handle. A switch body has a configuration in which the gear wheel metal fitting is rotated and slid with respect to the fixed contact via a handle metal fitting, a switch base that fixes the mandrel and has a fulcrum hole formed therein, and a wire rod folded into a substantially U-shape. The rotary arm is bent at a predetermined angle, and one end of the arm engages with the fulcrum hole, the middle part engages with the handle, and the other end serves as a pulling operation section. It is something.

According to the configuration of this invention, since the rotating arm is formed into a substantially U-shape, when one bent arm end of the rotating arm is locked to the fulcrum hole of the switch base,
The side having the arm end of the rotating arm can be locked to the surface of the switch base by the coil spring, and the substantially U-shaped shape of the rotating arm allows the switch base to function as a stopper for the handle. Therefore, the mandrel of the pull switch, in which the step wheel metal fittings, handle, coil spring, etc. are assembled, is attached to the switch base, and the middle part of the rotating arm is engaged with the handle, and the handle is rotated to release the coil spring. Assembly is facilitated because it can be assembled by locking the arm end in the fulcrum hole while being biased. Further, since there is no need to form a stopper portion on the handle, the structure is simplified, and the switch does not become large and there is no need to increase the thickness of the handle. Furthermore, since the rotating arm can be pulled in a direction perpendicular to the rotating direction of the handle, the fixed contact can be integrally formed on the extension of the electrical circuit board that forms the electrodes of the glow lamp socket, making it easy to manufacture lighting equipment. become.

Example A lighting fixture to which an example of this invention is applied is shown in the first example.
This will be explained based on FIGS. 23 to 23. In other words, this hanging ring-shaped two-light lighting fixture has two lights on, one light (on the high W side) lights, a miniature light, and an off operation, and its configuration can be roughly divided into two lights that are hung from the ceiling. It consists of a cord 1, a device main body 2, a composite socket 3, and stabilizers 4 and 5. The device main body 2 has a disk shape with a peripheral wall 2' hanging down, the lower side is closed with a lower cover 2a, and the upper surface has a cord cover 2b. The lower cover 2a and the device main body 2 are integrally connected by screws 8 which are butted together at the outer peripheral ribs 6 and 7, forming a space for storing parts such as a composite socket 3 inside, and a large number of heat radiation holes 2c (second, second, etc.). 3), and at the same time, a two-lamp integrated lamp support spring 10 is attached using screws 8. An umbrella-shaped cord cover 2b is attached to the top center of the device body 2, and the cord cover 2b is attached to the top center of the device body 2, and the cord cover 2b is attached to the top center of the device body 2, and the cord cover 2b is attached to the top center of the device body 2.
The lower end of the cord is inserted into the cord cover 2b, loosened appropriately, and passed through a support 12 provided on the instrument body 2, with a connector 1a provided at the tip. The composite socket 3 (for example, FIGS. 5 and 6) has a band-like outer shape and is attached to the approximate center of the lower surface of the device body 2, and stabilizers 4 and 5 are attached to both sides of the socket using screws 4' and 5'. However, 32W has a large wattage and is heavy.
Alternatively, the 40W boost type ballast 5 is placed on the center side of the device body 2, and the 30W single-wound ballast 4 is placed on the side away from the center to maintain the weight balance when the device body 2 is suspended by the cord 1. . The composite socket 3 has a pair of hooks 13 and 14 protruding from its upper surface, and the hooks 13 and 14 are hooked into a mounting hole 15 formed inside the cord cover 2b of the instrument body 2, and are secured with a screw 16 and a cutting claw 17. It can be securely attached to the instrument body 2. When viewed from above, this composite socket 3 includes a lamp socket 18, a screw-in type glow lamp socket 19, a swan type glow lamp socket 20, a pull switch 21, a small bulb socket 22, and a fuse from one end in the longitudinal direction as shown in FIG. The holders 23 are arranged substantially in a straight line.
The lamp socket 18 has lamp pin insertion holes 24, 2.
Connector portions 26a and 26b at the upper end of the lamp holder 26, which is provided with a numeral 5 at the lower end, are inserted into connection holes 100 and 101 of the composite socket 3. Further, glow lamps 28, 29 and miniature bulbs 30 are attached to the respective sockets 19, 20, 22, and annular lamps 31, 32 are attached to the lamp support spring 10 and the support pieces 26c, 26d of the lamp holder 26. The composite socket 3 has a circuit board 34 (a ninth
This electrical circuit board 34 is patterned to form the electrical wiring shown in FIG. , 5,
Further, it is connected to the connector 1a of the cord 1 by a connector pin 73 formed on the circuit board 34.

The composite socket 3 has a body 33 made of a thermoplastic resin, such as polypropylene, and a circuit board 34 patterned with a conductive plate made of copper, brass, etc.
The body 33 consists of a base 36 and a cover 37.
Base 36, glow lamps 28, 29 and miniature balls 30
mounting holes 28a, 29a, and 30a are formed, and the fuse holder 23 and the pull switch 21 are formed in the cover 37.
The mounting part 21a of the cord connector 1a, the storage part 1 of the cord connector 1a
It forms b. Further, a large number of mounting frames 38 are provided upright on the outer periphery of the base 36, and a guide taper 39 is formed inside the mounting frames 38. On the other hand, locking protrusions 40 are provided on the outer periphery of the cover 37 to protrude horizontally. By being guided and hooked on the guide taper 39 of the mounting frame 38, the two are connected and at the same time the electric circuit board 34 is held. In addition, in order to ensure the strength of the parts that receive the force applied when attaching and detaching the glow lamps 28, 29 and the small bulb lamp 30, each socket 1 of the base 36 is
A caulking protrusion 41 is provided protruding from the center of the lamp holders 19', 22' and the socket 20 at the center of the lamp holder 9, 22, a through hole 42 is formed in the cover 37, and the protrusion 41 protrudes from the upper surface of the cover 37 by connection. The upper end of the is caulked and fixed. On the other hand, the circuit board 34 is the circuit board 3
4 to the base 36, a large number of rectangular holes 43 are formed at predetermined positions, taking into account the parts that are particularly loaded.
A pin 44 is integrally formed on the base 36 in correspondence with the rectangular hole 43, and the circuit board 34 is pressed against the base 36, and the rectangular hole 43 is press-fitted into the pin 44 as shown in FIGS. 10 and 11. . During this assembly, the electric circuit board 34 and the base 36 are positioned by passing a jig through the guide holes 34a and 36a. Also, on the back side of the cover 37, there is a pressing protrusion 45 that presses down the circuit board 34, and a separation part 46 of the circuit board 34 (which is joined to prevent the pattern from separating during manufacturing). An insulating plate 47 is formed (FIG. 12) that insulates the parts (only a portion of which is shown in FIG. 9), which is separated by pressing when being attached to the device. The hooks 13 and 14 attached to the device main body 2 of the composite socket 3 are provided at intervals close to the maximum diameter of the cord cover 2b for stable locking, but the hooks 13 and 14 that are attached to the device main body 2 of the composite socket 3 are provided at intervals close to the maximum diameter of the cord cover 2b.
8 is the socket 1 that applies strength to the composite socket 3
8, 20, and 22.

Briefly explaining the assembly of the composite socket 3, a nut 21c for screwing the screw 16 is placed on the upper end of the boss 21b of the base 36, a switch stand 21e is placed on the base 36, and the nut 21c is held down. Next, the electric circuit board 34 is pressed onto the base 36, and the lower end of the shaft 88 of the switch block 21g is caulked and fixed to the shaft hole 89 of the switch base 21e via the electric circuit board 34. The cover 37 is placed over the electric circuit board 34 and held down. Incidentally, since the portions forming the central contact pieces 51a, 22a of the sockets 19, 22 of the circuit board 34 are bent vertically when installed on the base 36, they are bent into a horizontal position after being fixed with the cover 37.

To explain the composite socket 3 in more detail, the contact piece 50 that contacts the glow lamp pin (not shown) of the swan-type glow lamp socket 20 has a ninth contact piece 50.
As shown in the figure, it is formed integrally with the circuit board 34, but the longitudinal direction of the contact piece 50 is arranged in the same horizontal plane at right angles to the longitudinal direction of the composite socket 3 in which each socket 19 etc. are arranged in a straight line. . This is because the length of the contact piece 50 in the swan type is long in order to maintain elasticity, so the composite socket 3 is shortened in the longitudinal direction. Further, a connection terminal 53 for connecting the pin 52a of the noise prevention capacitor 52 is formed near the base contact piece 51 of the screw-in glow lamp socket 19 on the circuit board 34, and a pin insertion hole 54 is formed in the cover 37 correspondingly. and the cover 37
A guide plate 55 is suspended from the back side of the guide plate 55 (FIG. 13), and the connection terminal 53 is elastically contacted with the side surface of the guide plate 55 to apply initial pressure.
A groove 56 having a depth of about half the outer diameter of the pin 52a is formed on the side of the connecting terminal 53 to reduce elastic deformation of the connecting terminal 52 and eliminate plastic deformation when the pin 52a is inserted. This connection terminal 53 also serves as a connection terminal when an electronic starter 57 is used instead of the glow lamp 28, and when the electronic starter 57 is used, the noise prevention capacitor 53
2 is reliably prevented from being connected. The fuse holder 23 of the composite socket 3 is disposed at one end in the longitudinal direction of the composite socket 3 so as to be outside the cord cover 2b at the attachment position of the instrument main body 2, and the fuse holder 23 of the composite socket 3 is located at one end of the composite socket 3 in the longitudinal direction. The fuse holder 23 is arranged at right angles to the longitudinal direction of the composite socket 3 to shorten the length of the composite socket 3, and the height of the fuse holder 23 is the same as that of the stopper 48. A locking protrusion 60 is formed on the upper end surface of the fuse holder 23, and is set to ensure insulation between the electrical circuit board 34, which has a connecting terminal 59 serving as a fuse contact piece, and the appliance body 2. A locking protrusion 60 is fitted into a fuse hole 61 (FIG. 4) formed in 2. The cap 63 that closes the opening 62 of the fuse holder 23 has a fuse support part 64 protruding from its lower surface to form a fuse end positioning piece 64a, and has fuse holding hooks 65 hanging down from both sides. Holds the glass portion of the device in a removable manner. When the cap 63 holds the fuse holder 58 and inserts it into the holder 23 from the top side of the instrument body 2, the terminals 58a at both ends of the fuse 58 hold the connection terminals 59 of the circuit board 34, and the opening 62 closes. It has been accomplished. In addition,
Reference numeral 67 is a holding protrusion which also serves as a stopper for the fuse cap 63 at its upper end and prevents the connection terminal 59 of the circuit board 34 from floating at its lower end. Hold down the raising piece 68. Further, the fuse 58 can be easily replaced by removing the cap 63 from the top surface of the instrument body 2. At this time, since force is applied to the multiple sockets 3, a mounting piece 70 is provided protruding from the side of the fuse holder 23 to also serve as the mounting of the composite socket 3.
A hole 71 is formed at the tip thereof, and the cut and raised claw 17 of the instrument main body 2 is inserted into the hole 71, and the tip is fixed by twisting and engaging the lower surface of the hole 71.
Furthermore, pattern lines 72 are arranged between the connection terminals 59 of the fuses 58 on the circuit board 34 so as to cross the fuses 58, but this is done to avoid crossing the pattern lines on the circuit board 34 and to route the pattern lines. This is to avoid increasing the size of the composite socket 3 and complicating the structure due to its insulating means. That is, as is clear from FIG. 7, the fuse 58 is connected in series with the connector pin 73 connected to the connector 1a of the cord 1, the pull switch 21, and the primary side of the step-up ballast 5 on the power supply circuit board 34. However, as shown in FIG. 15, due to the arrangement of these and the miniature bulb socket 22, the pattern wire 72 connected to the connector pin 73 has a wire that intersects with the fuse 58, which has a longer wire length than other wiring methods. It becomes effective. Further, the wiring from the connector pin 73 of the circuit board 34 to the contact pieces 18a, 18b of the lamp socket 18 is such that the connector pin 73 is located in the center of the composite socket 3 and the contact piece 18 of the lamp socket 18
Since a and 18b are located at the ends of the composite socket 3 and the glow lamp sockets 19 and 20 are located between them, the pattern line 74, which is a common line to the contact pieces 18a and 18b, branches into two and forms a swan. The wiring is arranged so as to surround the contact piece 50 of the type glow lamp socket 20, and by avoiding three-dimensional intersections, the structure of insulation etc. is simplified, and the composite socket 3 is not made large.

The pull switch 21 of the composite socket 3 is operated by placing the nut 21c on the upper end of the boss 21b of the base 36 before the electric circuit board 34 is attached to the base 36, and then tightening the nut 21c on the boss 21b.
A projection 77 at the upper end of the nut 21c is used to stop the nut 21c from rotating, and a switch stand 21e made of a thermosetting resin such as urea resin is placed on the base 36. Note that the base 36 side is stepped down from other parts by the thickness of the switch stand 21e. At this time, base 3
The guide hole 80 fits into the positioning protrusion 79 of No. 6, and the boss 81 fits into the boss 21b to hold the nut 21c. Also, the shaft caulking portion of the switch stand 21e is fitted into the hole 21j of the base 36. In this state, the electrical circuit board 34 is placed between the base 36 and the guide ribs 36a, 21i on the switch stand 21e and fixed as described above. Further, the vertical arm 83 of the switch block 21g constituting the switch body is inserted into the arm hole 84, and the arm end 86 bent at right angle of the rotating arm 85 formed of wire and serving as the operating direction changing member is inserted into the fulcrum hole 87. , and the shaft 88 is connected to the circuit board 34 and the switch base 21e.
The shaft 8, which is the mandrel, is inserted through the shaft hole 89 of the shaft caulking part.
Caulk the bottom edge of 8. Now switch block 2
1g is supported in a cantilevered state, and by fixing the cover 37 to the base 36, the cover 37 holds the electric circuit board 34 and also the switch stand 21e. When the composite socket 3 is installed, the screw 16 is tightened to the nut 21c, which is the attachment part of the pull switch 21, and the pull switch 21 is fixed, and the nut 21a is provided near the connection 83a, which is the pull operation part of the pull switch 21. This prevents the pull switch 21 and the composite socket 3 from being deformed by the load applied when the switch is operated. The switch base 21e has a support portion 90 for the connector pin 73, and the base portion of the connector pin 73 is held in an upright position by the support portion 90. In this pull switch 21, a plurality of fixed contacts 91
is formed on the circuit board 34, but this fixed contact 91
A movable contact plate 9 that supports the
A tapered support portion 93 for preventing the reverse rotation of the switch 2 is integrally formed with the switch base 21e to ensure wear resistance. Further, the switch case 21a formed on the cover 37 has the same height as the stopper 48, etc., and remains open at the upper end, and when the composite socket 3 is attached to the instrument body 2, it is closed by the instrument body 2 and the instrument is closed. The main body 2 also serves as a lid. The switch block 21g has a spring receiver 94 fixed to the upper end of the shaft 88, and a movable contact plate 92 in the middle of the shaft 88.
A rotary plate 95 that is a handle is rotatably provided, a claw plate 95a that is a handle metal fitting is attached to the movable contact side 92 of the rotary plate 95, and a torsion plate that is a coil spring is installed between the rotary plate 95 and the spring receiver 94. Both ends of the coil spring 96 are engaged with the spring receiver 94 and the rotary plate 95 to bias the rotary plate 95 in one direction and also bias the rotary plate 95 in the axial direction to move the movable contact plate 92. The fixed contact 91 is elastic. The rotating arm 85 has a U-shape and is bent at a predetermined angle.One arm end 86 has a support hole 87.
At the same time, the intermediate part 97 is caught in the catch recess 98 of the rotary plate 95, and the connecting part 83a which becomes the operating part is bent at the tip and connected to the upper end ring part of the vertical arm 83. Can be hung from a drawstring at the bottom. When this vertical arm 83 is pulled in the vertical direction, the rotating arm 85 rotates around the arm end 86 (imaginary line in Figure 20), and the rotating arm 85 changes from a horizontal U-shaped posture to a vertical U-shaped posture, so it rotates. The plate 95 rotates to perform a switch operation. A guide body 21f is formed on the switch base 21e when the rotating plate 95 rotates.
serves as a guide to prevent the rotating plate 95 from shaking, and the rotating plate 9
5 can be prevented from twisting.

FIG. 23 shows the operating state of the pull switch. That is, a ₁ and a ₂ are at the arm end 86 in the returned state.
is locked in the fulcrum hole 87 on the upper surface side, b ₁ , b ₂ and c ₁ , c ₂ are in the middle of operation, d ₁ and d ₂ are in the operating state and the arm end 86 is in the fulcrum hole 87 on the lower surface side. It is in a locked state. By making the direction in which the pull switch 21 is pulled perpendicular to the rotating direction of the rotary plate 95, the plurality of fixed contacts 91 can be connected to the circuit board 34.
It can be formed integrally with the body, and can have a simple structure that requires only press processing. In addition, the pulling direction is changed by the lever action of the rotating arm 85, the rotating arm 85 is formed of a wire rod and has a small contact area with the rotating plate 95, and the fulcrum of the rotating arm 85 is connected to the thermoplastic switch base 21e. Because it is formed, the operation is smooth and there is little wear. Further, since the arm end 86 is bent at a right angle, the stopper that restricts the amount of rotation of the rotary plate 95 is achieved by locking the arm end 86 to the edge of the support hole 87. There is no need to construct a stopper portion, the structure is simplified, and the strength of the rotary plate 95 is not required. Furthermore, since the connecting portion 83a between the vertical arm 83 and the rotating arm 85 is located within the composite socket 3, the vertical arm 83 is in a state of protruding from the composite socket 3, but the connecting portion 83a can be opened by pulling the vertical arm 83. By locking the vertical arm 83 exposed from the composite socket 3 to a locking piece 99 (FIG. 8) formed on the lower surface of the base 36, it can be kept out of the way during packaging, and the arm 83 can be removed inadvertently. It prevents bending and allows for rough handling. It goes without saying that the vertical arm 83 is located at the hanging center of the fixture body 2 in order to prevent the lighting fixture from shaking when the switch is operated.

By tilting to this position, the center of gravity of the instrument main body 2 is located on the extension line, and the vertical arm 83 of the pull switch 21 is located on the extension line. Further, a bridge 102 is provided between the pair of connection holes 100 and 101 to ensure strength, and an electric path is formed inside the bridge 102 to be routed to the contact piece 50 of the swan type glow lamp socket 20. The pattern structure of the electric circuit board 34 is simplified by extending the pattern lines 103 of the board 34. The lamp socket 18 has a main body 23 as shown in FIG. 5, has connector parts 26a and 26b attached to the connection holes 100 and 101 at the upper end, and has a terminal 105 on the side thereof via a guide-cum-insulating rib 104.

[Effect of idea]

According to this invention, since the rotating arm is formed into a substantially U-shape, when the bent end of the rotating arm is locked in the fulcrum hole of the switch base, the arm of the rotating arm is moved by the coil spring. The side having the end can be locked onto the surface of the switch base, and the substantially U-shaped shape of the rotating arm allows the switch base to function as a stopper for the handle. Therefore, the mandrel of the pull switch, which has a gear wheel metal fitting, a handle, a coil spring, etc. incorporated in the mandrel, is attached to the switch base, and the middle part of the rotating arm is engaged with the handle, and the handle is rotated to attach the coil spring. Assembling can be done by locking the end of the arm in the fulcrum hole while pushing the arm, making it easy to assemble. Further, since there is no need to form a stopper part on the handle, the structure becomes simple, and the switch does not become large and there is no need to increase the thickness of the handle. Furthermore, since the rotating arm can be pulled in a direction perpendicular to the rotating direction of the handle, the fixed contact can be integrally formed on the extension of the electrical circuit board that forms the electrodes of the glow lamp socket, making it easy to manufacture lighting equipment. It has the effect of becoming
