[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, an example of a conventional example such as Utility Model Publication No. 58-54752 is shown in FIGS. 24 and 25. That is, a wheel metal fitting 151, a handle 153 with a handle metal fitting 152, and a coil spring 15 are attached to the shaft 150.
4 are fitted and supported by the collar 155, a support fitting 156 is fixed to the end of the mandrel 150, one end of the coil spring 154 is supported by the support fitting 156, and the handle 153 is urged back, and the handle 153, Step car metal fitting 1 via handle metal fitting 152
51 toward the collar 153 side. The fixed contact 1 is tapered on the surface of the base 157 by fitting the lower end of the mandrel 150 into the caulking hole 158 of the base 157.
60 and the corrugated wheel metal fittings 151 are brought into elastic contact with them. handle 15
By pulling the pull member 159 connected to 3 in a direction perpendicular to the mandrel 150, the handle 153 is rotated and the gear wheel fitting 151 is slid onto the fixed contact 160. When the pull member 159 is released, the handle 153 is returned to its original position by the coil spring 154, but the wheel metal fitting 151 is not rotated because it is locked to the taper of the fixed contact 160.

However, since the pull switch is normally operated in a vertical direction, the shaft 150 is in a horizontal position and the fixed contact 160 is in a vertical position. Therefore, for example, in lighting equipment, pull switches and
When applied to a composite socket that integrates a glow lamp socket and a small bulb socket, the circuit board that integrally forms the fixed contact 160 of the composite socket and the contact piece of the socket needs to be in a vertical position, and usually This has the disadvantage that it does not match with the socket group which is in a vertical position, and the configuration of the circuit board becomes complicated.

[Purpose of invention]

The purpose of this invention is to provide a pull switch that can be easily applied to the above-mentioned composite socket.

[Disclosure of invention]

This device consists of a switch body in which a contact point is actuated by rotating a handle that is pivoted on a shaft and biased to return by a predetermined angle, one side piece, an intermediate part, and the other side piece, and the one side piece and an intermediate part are substantially U-shaped in a continuous arc shape, and the arm end at the tip of the one side piece is pivoted to the switch body, and the tip of the other side piece is provided with a drawstring connecting part. a conversion member, the one side piece extends parallel to the return direction of the handle from the end of the arm pivoted to the switch body when the handle is in the return state, and the intermediate portion slides on the handle in the return state. The operation direction changing member is disposed so as to be movably engaged and the other side piece extends in the rotational direction of the handle, and the arm end pivoted on the switch body is used as a fulcrum, The handle can be rotated by a predetermined angle by pulling the drawstring connecting part in the same direction as the mandrel and rotating the operation direction changing member so that the handle slides from the intermediate part to the one side piece. It is characterized by the following.

Since the operating direction of the pull switch and the shaft are in the same direction, when applied to the above-mentioned composite socket, it becomes easy to form a contact piece such as a socket on the circuit board. Moreover, since the switch body is the same as the conventional switch by simply adding an operation direction changing member, it is possible to share parts and reduce costs. Further, since the operation direction changing member operates by lever action, the operation becomes smooth.

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 upper center of the instrument body 2, and the lower end of the cord 1 is inserted into the cord cover 2b through the cord adjuster 11, and is loosened appropriately to attach to the support provided on the instrument body 2. 12, and a connector 1a is provided at the tip. The composite socket 3 (for example, FIGS. 5 and 6) has a strip-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.

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 by a screw 16 and a cut-out 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 27a and 27b 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,
It is connected to the connector 1a of the cord 1 by a connector pin 34a 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.

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, press the circuit board 34 onto the base 36, and insert the lower end of the shaft 21h of the switch block 21g into the shaft hole 21f of the switch block 21e on the circuit board 34.
Fix by caulking. Attach the cover 37 to the circuit board 3
4.Put these on top and press them. In addition, the circuit board 3
Center contacts 51a, 22 of sockets 19, 22 of No. 4
Since the portion forming a is vertically bent at the stage of installation on the base 36, it is 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 connecting terminal 52 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 fuse 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. A cap 63 that closes the opening 62 of the fuse holder 23 has a fuse support portion 6 on the lower surface.
4 is provided protrudingly to form a fuse end positioning piece 64a, and fuse holding hooks 65 are attached from both sides.
hangs down, and the hook 65 holds the glass portion of the fuse 58 in a detachable manner. When the cap 63 holds the fuse 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 66 of the circuit board 34, and the opening 62 closes. That's right. In addition, 6
Reference numeral 7 is a holding protrusion which also serves as a stopper for the fuse cap 63 at the upper end and prevents the connecting terminal 59 of the circuit board 34 from floating at the 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, force is applied to the composite socket 3, so a mounting piece 70 is provided protruding from the side of the fuse holder 23 to also serve as a mounting point for the composite socket 3, and a hole 71 is formed at the tip of the mounting piece 70 so that the instrument body 2 can be cut and raised. Insert the claw 17 into the hole 71 and twist the tip to open the hole 7.
It is fixed by being locked to the lower surface of 1. Also, the connection terminal 5 of the fuse 58 on the circuit board 34
The pattern wire 72 is arranged so as to cross the fuse 58 between the wires 9 and 9. This is to avoid crossing the pattern wires on the circuit board 34, and also to increase the size of the composite socket 3 and insulate it by routing the pattern wires. This is to avoid complicating the structure due to means. That is, as is clear from FIG. 7, the fuse 58 is connected to the connector pin 73 connected to the connector 1a of the cord 1, the pull switch 21, and the step-up ballast 5 on the power supply, that is, the circuit board 34.
It is connected in series with the primary side of
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 is more effective when the wiring that crosses the fuse 58 is more effective than other wiring methods. 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 pieces 18a, 18b of the lamp socket 18 are connected to each other.
Since 18b is located at the end 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 lines to form a swan type glow. The wiring is arranged so as to surround the contact piece 50 of the lamp socket 20 to avoid three-dimensional intersections, thereby simplifying the structure for insulation, etc., and also preventing the composite socket 3 from increasing in size.

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 installing the composite socket 3, the screw 16 is inserted into the nut 21c.
The nut 21c is provided near the pull switch 3 to prevent the composite socket 3 from being deformed by the load applied when the switch is operated. Note that the switch stand 21e has a support part 90 for the connector pin 73,
The base portion of the connector pin 73 is held in an upright position by the support portion 90. This pull switch 2
In No. 1, a plurality of fixed contacts 91 are formed on the circuit board 34, and a tapered support portion 93 that supports the fixed contacts 91 and prevents the movable contact plate 92, which is a gear wheel metal fitting, from reversing, is integrated into the switch base 21e. formed to ensure wear resistance. Further, the switch case 21e 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. Switch block 21g has shaft 8
A spring receiver 94, which is a supporting metal fitting, is fixed to the upper end of the shaft 88, and a movable contact plate 92 and a rotary plate 95, which is a handle, are rotatably provided in the middle of the shaft 88.
A claw plate 9 which is a handle metal fitting is attached to the movable contact side 92 of 5.
6 is attached, and a torsion coil spring 96, which is a return spring, is interposed between the rotary plate 95 and the spring receiver 94, and both ends of the torsion coil spring 96 are locked to the spring receiver 94 and the rotary plate 95, so that the rotary plate 95 is oriented in one direction. The movable contact plate 92 is biased by biasing the rotating plate 95 in the axial direction.
is elastically attached to the fixed contact 91. Rotating arm 85
has a U-shape consisting of one side piece, an intermediate part 97, and the other side piece, and an arm end 86 serving as a pivot is formed at the tip of one side piece, and a drawstring connecting part 83a is formed at the tip of the other side piece. is curved, and the one side piece and the middle part 97 are continuous in an arc shape, the arm end 86 engages with the fulcrum hole 87, and the middle part 97 slides into the hook recess 98 of the rotary plate 95 which becomes a handle. The drawstring connecting portion 83a is freely engaged and connected to the upper end loop of the vertical arm 83, and the drawstring is suspended from the lower end of the vertical arm 83. In this case, the rotating arm 85 is connected to the rotating plate 9
5, one side piece extends parallel to the return direction of the rotary plate 95 from the arm end 86 which is pivoted to the fulcrum hole 87 in the returned state, and the intermediate portion 97 can freely slide into the hook recess 98 of the rotary plate 95 in the returned state. The drawstring connecting portion 83a of the other side piece is disposed so as to be engaged with and extend in the rotational direction of the rotary plate 95. When this rotating arm 85 pulls the vertical arm 83 in the vertical direction, that is, pulls the drawstring connecting portion 83a to move in the same direction as the mandrel 88, the rotating arm 85 moves to the second position with the arm end 86 as a fulcrum.
As shown by the imaginary line in Figure 0, the rotary plate 95 rotates from a horizontal U-shaped posture to a vertical U-shaped posture, and as a result, the rotary plate 95 slides from the intermediate portion 97 to one side through the arc-shaped portion and rotates. The plate 95 rotates to perform a switch operation. And when the rotary plate 95 rotates, the switch base 21
The guide body 21f formed at e serves as a guide to prevent the rotating plate 95 from wobbling, and can prevent the rotating plate 95 from twisting.

FIG. 23 shows the operating state of the pull switch. That is, a ₁ , a ₂ are in the return state, b ₁ , b ₂ and
c ₁ and c ₂ are states in the middle of operation, and d ₁ and d ₂ are states in which the arm end 86 is locked in the fulcrum hole 87 in the operating state.
By making the pulling direction of the pull switch 21 perpendicular to the rotating direction of the rotary plate 95 in this way, a plurality of fixed contacts 91 can be integrally formed on the circuit board 34, and the structure can be made simple by just press processing. be able to. 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 the contact area with the rotating plate 95 is small, and the fulcrum of the rotating arm 85 is set to the thermoplastic switch base 21e. Because of this structure, the movement is smooth and there is less 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 fulcrum hole 87.
Since there is no need to construct a stopper section, 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.

Connection holes 27a, 27b of lamp socket 18
is provided at the end of the composite socket 3 opposite to the fuse holder 23, and in particular, by providing it at the end of the composite socket 3 in the longitudinal direction, the dimensions of the holder 23 of the lamp socket to be attached to the annular lamp are shortened and miniaturized. We aim to Also, a pair of connection holes 27a, 27
b are connection holes 27a arranged in the longitudinal direction on the high W side;
are placed on the outside, and the bases of the annular lamps 31 and 32 to be connected are placed on the same side with respect to the device body 2, and moreover, the direction in which they are lined up is precisely at a certain angle with respect to the longitudinal direction of the composite socket 3. 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. In addition, a bridge 102 is provided between the pair of connection holes 27a and 27b 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 holder 23 constructed as shown in FIG. 5, has connector parts 26a and 26b attached to connection holes 27a and 27b at the upper end, and a terminal 105 on the side thereof through a guide-cum-insulating rib 104.
A protrusion 107 that engages with the engagement hole 106 of the instrument body 2 is formed at the upper end, and connector portions 26a and 26b are formed.
Temporary fixing hooks 108 are formed on both sides of the connector portion 26a in the alignment direction, and the hooks 108 are engaged with the upper surfaces of the connection holes 27a and 27b, and the protrusions 107 are engaged with the engagement holes 106 to firmly maintain the posture of the connector portion 26a. ,2
