Description of the invention (\) Field of invention (please read the precautions on the back before filling out this page) This invention is about a thermal circuit protector device, and its function is also an ON / OFF switch, especially with more Simple and less expensive construction. The thermoelectric color change charge / LiLiLiBook can also prevent continuous or repetitive overload when trying to manually control. First, "*", "'' First, <: '* ·' · ·" Description of the prior art Switch is known as a thermal protector circuit breaker or switch. The fast-acting bimetal element has been used as an example of a similar thermal protector, which uses a palm-shaped insulating material to protrude between the switch contacts. When the bimetal element senses ... Λ ...-. , * &Quot; ,, .....- When it is overloaded. See U.S. Patent Nos. 5,089,799 and 5,264,817 using such flag-shaped thermal protector switches. Other thermal circuit protector devices used as switching functions are operated through push button switches. When the device cuts off the circuit to restore the circuit protector, the push button switches must be pulled out manually. Butler's US Patent No. 3,311,72 5 shows this general type circuit breaker / switch. Another type of temperature switch (thermostatic switch) has a fast-acting disc, which can be reset by a push button switch. For example, U.S. Patent Nos. 4,79 1,397 and 4,628,295 are disk-type devices. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Although there are many conventional ways to make more complicated and therefore expensive thermal circuit breaker devices. For example, those described in U.S. Patent Nos. 4,931,762 and 4,258,349. Another thermal circuit breaker device proposed by the same inventor here uses a bimetal element as a contact arm. See U.S. Patent No. 5,847,638. This paper size is in accordance with Chinese National Standard (CNS) A4 (210 × 297 mm) 4T3757 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Β7. When the description of the invention (Η "), the trip actuator has additional surfaces and sockets Lap. The protruding pins of the horizontal feet are accommodated in the vertical channel of the housing, and the upright feet contact the contact actuator via the two contact actuators and the trip actuator interface. When the bimetal reacts to an overcurrent, it moves to contact the horizontal foot of the trip actuator, pivots the trip actuator, and disengages the upright foot of the trip actuator from the contact actuator. The inherent pressure of the arm can open the contact in the event of overcurrent / overheating in the bimetal element. The bimetal element is of the 'IΓ' type having two arms. One end of the other arm is fixedly connected to the first terminal, and one end of the opposing arm is preferably fixedly connected to the contact arm via a conductive lapping piece. The bimetal element electrically connects the first terminal to the movable contact arm and its movable contact. The bimetallic element shows a change in thermo-thermal response in shape or curvature, so that the unrestricted free end base of the 'U' will react to a predetermined current to the bimetallic element. A temperature rise will occur, and it will bend upward toward the trip actuator Level feet. A pressure device in the form of a single compression spring is installed on the bottom side of the rocker and the upper end of the upright leg of the trip actuator. Therefore, a single spring can simultaneously pressurize the rocker to move it to the 'of Γ position, and move the trip actuator to its neutral position to contact the contact actuator when there is no overload condition. Even when the rocker is held in its 'on' position, the extension under the rocker cannot move the contact actuator into the contact-closed state, because one end of the contact actuator will not be in contact with the trip actuator. While being restricted. When the rocker is not held in the 'on' position when overloaded, spring pressure forces the rocker toward the 'off' position. Once the bimetal element has been cooled enough, it will not be overlapped. (Please read the precautions on the back before filling out this page.) This paper size applies to China National Standard (CNS) A4 (210X297 mm) 473757 A7 B7 5. In the description of the invention (5 *), the spring returns the trip actuator to the 'restoration' position so that its upright foot can touch the actuator.

Now refer to the diagram in more detail. Figure 1 shows a generally shaped hollow chamber housing 20 with a generally rectangular upward opening to accommodate the following parts. Pivotable The installed rocker 22 or other manipulator has a laterally extending shaft-forming protrusion 22a received in the shaft opening 20a of the side wall 20b of the housing. The side wall 20b of the housing is formed with a formed vertical rail 20c slidably received at the contact On actuator 24 The track guide protrusions 24a, I and the shock-forming sockets 201 are shaken to accommodate the shaft-forming protrusions 261 on 26. Therefore, the 'L'-shaped tripping actuator 26 is pivotably mounted in the housing 20. The sockets 20d contains the surface 201 overlapping with the stop surface 20f, thereby restricting the rotation of the tripping actuator 26. The integrally formed insulating sleeve 20e in the housing insulates the terminal element 34, and the terminal 34 has a fixed contact 28 installed on the terminal element One end of 34. A load and live wire terminal (32, 34 each) extends through a slot in the bottom wall 20 i of the housing. The load terminal 32 contains a threaded opening 32a to accommodate an adjustment or scale bolt 36. The load terminal 32 faces upward It extends upward along the housing end wall 20g and is connected to the bimetal element 38. This element 38 is shown in Fig. 1 and has two arms 38a and 38b parallel to each other in a "U" shape. Bimetallic elements This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) 473757 Printed by A7 B7, Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention 38) Oriented approximately parallel to the bottom wall of the housing In the plane of 20i, there is a thermal response characteristic, such as bending the bimetal element toward the tripping actuator 26 when the temperature rises during an overcurrent condition. The end of the scale bolt 36 contacts the lower surface of the bimetal element 38 to form a neutral appearance of the bimetal element 38, thereby forming the degree of deformation required for the tripping actuator 26 to escape. The "U" -shaped bimetal element 38-the end of the support arm 38a is connected to the fixed end of the movable contact arm 40 via a conductive bonding piece 52. The bimetal member 38-the support arm 38a can be arbitrarily directly connected to the fixed end of the movable contact arm 40. The other arm 38b of the bimetal element 38 is connected to the special application portion 32b of the load terminal 32 so that a current can flow through the bimetal element 38. The movable contact arm 40 contains a spring metal material, and a free end is pressurized upward away from the fixed contact element 28. The free end includes a contact element 30. The fixed contact element 28 is mounted on the live wire terminal 34. When the movable contact arm 40 is pressed downward by the contact actuator, the movable contact element 30 closes the circuit with the fixed contact element 28. The rocker or manipulator 22 is pivotably mounted in the shaft opening 20a, and is pressurized and moved by the coil spring 42 to the open or 'of' position. The integrally formed extension 22b or the drooping post is integrally installed in the rocker, and when the rocker 22 is in the 'on' position, it is approximately vertically oriented (see FIG. 8). The rocker extension surface 22c constitutes the first The engaging device is movably engaged with the upper surface 24d of the contact actuator at least when the rocker 22 is in the 'on' position. Another actuator hook 22i is formed in the rocker extension 22b as a second engagement device. At least when the rocker 22 is in the 'of Γ position, the actuator hook 22i is movably engaged with the contact actuator post 24. i convergence. -9- This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the notes on the back before filling this page) 473757 A7 B7___ 5. Description of the invention (S) (Please read the notes on the back first Please fill in this page again.) The contact actuator 24 is installed between the pressurized movable contact arm 40 and the rocker 22. The contact stop 24b overlaps with the contact stop 22g on the lower surface of the rocker. At least when the rocker 22 is in the 'off' position, the upward movement of the right end can be restricted (as shown in Fig. 5). This upward movement is affected by the upward bias of the contact arm 40 against the contact actuator surface 24h. The rocker 22 is pressed toward the 'of Γ position by the reed spring 42 and is overlapped with the inner wall 20 j of the vertical rail of the housing by the rocker position stop 22h to stop at the appropriate' of f 'position. In the 'on' position, the top surface of the contact actuator 24 is a stopper 24e on the top surface of the actuator, which is biased upward by the contact arm 40 to provide sufficient pressure to overcome the minimum spring pressure of the rocker toward the 'off' position.

The side wall 20k overlaps and stops there, as shown in FIG. The left end of the contact actuator 24 has a recess 24f (as shown in the figure), which is used to arbitrarily contact the groove-shaped stopper portion 26d of the trip actuator, the purpose of which will be described later. The consumer actuator of the Intellectual Property Bureau of the Ministry of Economic Affairs has printed an unlocking actuator 26 which is an "L" shape, with horizontal and vertical feet (26 b and 26 each, and the horizontal foot 26 b is located on the trackable contact arm. Between 40 and bimetal element 38. A shaft forming protrusion 26a on the trip actuator 26 pivotally supports the trip actuator 26 in a molded socket 20d formed by the housing. The shaft forms an extension of the protrusion The stop surface 26 f is formed. The socket 20 d includes the surface 201 and the stop surface 26 f of the trip actuator in the rest position, as shown in FIG. 5, thus restricting the rotation of the actuator in that direction. The vertical leg portion 26 c rises above the surface 26 d. Usually, it contacts the recess 24f of the contact actuator to prevent the concave end of the contact actuator from going downwards. -10- This paper applies Chinese National Standard (CpS) A4 Specifications (210 X 297 mm) 473757 A7 __ B7____ 5. Description of the invention (1) (Please read the precautions on the back before filling this page) Move. The lower surface 22c of the joystick is at least moved to the 'on' position 24d on the surface of the contact actuator when the contact is activated The actuator 24 pivots where it overlaps with the surface 26d of the trip actuator. This pivoting action moves the right end of the contact actuator 24 (as shown in the figure) under the meat, and drives the surface 24 h downward to resist the movement. Contact arm 40 to close the contact elements (28 and 30). When the trip actuator 26 is pivoted or 'unbuttoned' by the upward movement of the overheated bimetal element 38, the surface 26d of the trip actuator 26 is from the edge point The recessed part 24f of the actuator is moved out. This releases the pivoting of the recessed end, so the contact actuator 24 will not drive the movable contact arm 40 downward, regardless of whether the rocker 22 is moved or not. Between the vertical foot 26 c of the trip actuator and the underside of the rocker 22, press the rocker toward the 'οίΓ position. The orientation of the spring 42 causes the spring force vector to slightly pass through the pivot of the trip actuator forever. The axis of the shaft (usually shown at 26g), forever forces the joystick toward the 'of Γ position, and forces the trip actuator to the neutral or restoring position. Printed in Figure 5 of the Consumer Cooperative of the Intellectual Property Bureau, Ministry of Economic Affairs, shows The lever 22 is in the "off" position of the spring pressing, and the trip is activated. 26 In the 'recovery' position, and the concave end of the contact actuator overlaps with the release stop 26d of the actuator. The actuator hook 22i is surely engaged with the engagement post 24i to ensure that the contact actuator 24 Proper positioning. The upward bias of the movable contact arm 40 pushes the contact actuator 24 up until the contact actuator 24 overlaps the rocker on the surfaces 22g and 22c. Figure 6 shows the present invention and its rocker in the The 'on' position shifts, and pressure is applied to the left part of the joystick (as shown). The rotation of the joystick moves the lower surface 22c through the contact actuator surface 24d, pressing the contact actuator down- 11-This paper size is in accordance with Chinese National Standard (CNS) A4 (210X297 mm) 473757 A7 B7 V. Description of the invention (I. ) (Please read the precautions on the back before filling out this page). Move it when it pivots on the concave end held in place by the trip stop 26d. The contact actuator 24 thus transfers downward pressure to the contact arm 40 at 24h, closing the contact elements 28 and 30. Figure 7 shows the device in a closed position without overload. The rocker 22 is completely pressed to the 'on' position, in which the lower surface 22c of the rocker extension rests on the stop portion 24e of the 'on' position, and the contact point actuator makes the movable contact arm 40 resist its biasing force, so The connecting elements (28 and 30) can be connected, and the rocker is overlapped with the vertical rail side wall 20k by its position stop 22f, and is restricted to the on 'position. The bias of the compression spring 42 is insufficient to overcome the resistance of the lower surface 22c of the rocker extension to the stopper 24e of the contact actuator 'on' position. Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 8 shows the device in the open position under an overload condition, irrespective of whether the joystick 22 is manually held in the 'on' position. Under an overload condition, the device is subjected to an electrical load greater than its rating, causing the bimetallic element 38 to be heated and bent upward and contacting the trip actuator horizontal leg 26b. The bias of this contact and element 38 overcomes the bias of the compression spring 42 and causes the tripping actuator to pivot about the pivot protrusion 26a against the molded housing socket 20d. As a result, the tripping actuator vertical leg 26c is turned outward (counterclockwise as shown in the figure) toward the housing end wall 20g. This rotation moves the trip stop 26d out of contact with the corresponding concave end 24f of the contact actuator 24. The concave end then drops down until it contacts the movable contact arm 40. The contact actuator overlaps the movable contact arm 40 at the concave end 24 and the lower surface 22o. The movable contact arm 40 drives the contact actuator toward the rocker until the lower surface 22c is limited by the contact. As shown in the figure, the fire and the surface 22g. If the shape of the contact actuator and the rocker changes from _Figure-12- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 473757 A7 B7_ V. Description of the invention (M) (Please read the precautions on the back before filling this page) to show those changes. This movement displaces the plane of the contact actuator and disengages the contact actuator 'on' position stop portion 24e from the rocker surface 22c. Fig. 8 shows the operation of "free tripping", in which the contact remains "open" under an overcurrent, regardless of whether the joystick is pressed and held in the "on" position. Figure 9 shows the invention and its joystick 22 transition after an overload condition. The compression coil spring 42 drives the rocker to the 'of Γ position, and slides from the stopper 24e to the surface 24d of the contact actuator on the rocker surface 22c, because the contact actuator 24 is displaced in a plane as described above. The rocker actuator hook 22i is engaged with the engagement post 24 ί, so that the concave end of the contact actuator 24 is raised to ensure the proper orientation of the contact actuator 24 with respect to the release and detent portion 26d of the release actuator. When the bimetal element 38 cools and returns to its undeflected shape, the trip actuator 26 rotates (clockwise as shown) to the position shown in Figure 2 due to the compression of the compression coil spring 42 and the surface 2 6d moves below the surface 24f of the pinch actuator. The device then returns to the position shown in Figure 5. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, another embodiment is shown in FIG. 10, in which the housing 20 is modified to include a housing stop 20f to perform the functions of the rocker stop surfaces 22g and 22h of the first embodiment. . Housing The housing stop 20f is used to restrict the upward movement of the right end (as shown) of the actuator 24, and is also used as the 'off' position stop of the rocker 20. The modified joystick used in the first alternative embodiment is shown separately in FIG. A second alternative embodiment is shown in FIG. 12, wherein the rocker extension 22b includes a protruding portion 22d facing inward as a first engagement device, which contacts the connection at least when the rocker is moved to the 'on' position The lower surface of the point actuator is opposite to the actuator hook of the first embodiment. This can ensure that the recess 24f of the contact actuator is relatively -13- This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) — 473757 A7 B7 V. Description of the invention (A) (Please read the precautions on the back first (Fill in this page again) Set the 26 slot 26d of the trip actuator correctly. The contact actuator 24 does not include the rocker engagement post in this second alternative embodiment, but instead contains a restoring surface 24g, which is specifically used to contact the auxiliary surface of the trip actuator. 13 and 14 each show a modification for a second alternative embodiment. The characteristics of the above embodiments, as well as those disclosed in the pending patent applications cited above, can be combined in whole or in part to obtain many changes in different applications. Many of these characteristics are described below, and will become clearer with reference to this article and the references. Any of the above embodiments may be modified to include a remote sensing device. This modification has a bimetal element 38 completely separated from the switch circuit between the terminals 32 and 34, and each arm 38a and 38b has an independent terminal. The bi-metal element 38 is thus connected to the zero circuit so that the switching circuit is overloaded by a long-distance source and is overloaded by H (ο p e η). Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the second long-distance sensing structure contains a solid-state sensor to detect when a special voltage limit is reached in the circuit, or after the switching circuit is closed, the specified predetermined programming When the time limit is reached. When the solid-state predetermined programming time limit is reached, the sensing circuit activates the solid-state switching circuit to divert an appropriate current to ground via a bimetal element. The current shunted to ground via the bimetal element is sufficient to cause the bimetal element to overheat, so the bimetal element can actuate the trip actuator and open the contacts 28 and 30 of the switching circuit. Therefore, the bimetal element not only provides the protection characteristic of general current, but also can be used as the driving mechanism of the shunt current when it is guided by the sensor, which is used to affect the opening of the switch contact. Although many situations can be monitored, depending on the solid state sensing -14- This paper size applies Chinese National Standard (CNS) A4 specification (210 × 297 mm) 473757 A7 B7 V. Description of the invention (6) (Please read the precautions on the back before Fill in this page) according to the program of the device. 'The bimetal shunt-to-ground configuration of the solid-state switch is a very important feature. Because this still makes the double metal cymbals perform the general overcurrent protection function. Many choices or combinations of conditions can be monitored by sensors, such as time, ground fault, low or undulating voltage, etc. It is also within the scope of the present invention to replace the bimetallic element with another biasing device, such as a solenoid, in which the armature of the solenoid is configured to generate a force against the tripping actuator 26, making the circuit open. The solenoid replaces the bimetal in this modification and is used as another means to actuate the trip actuator 26. This embodiment eliminates the need for the scale bolt 36 and its threaded opening 32a. The solenoid can also be controlled using a remote trip circuit connected to the neutral terminal. Combinations of the above variations are also within the scope of the invention. For example, bimetal components can use solid-state switches but no solid-state sensor circuits. The solid-state switch of this design is controlled by a remote sensor circuit. It applies a signal to the terminal to actuate the solid-state switch, causing it to shunt a control current through the bimetallic element to ground, or to a neutral point, thereby tripping the mechanism And turned on the mechanism switch. Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Another example is the use of solenoids instead of bimetals in conjunction with solid-state switches. The solid state switch is controlled by a remote sensor circuit. It applies a signal to the terminal to actuate the solid state switch, causing it to apply current to the screw f, thereby tripping the mechanism and turning on the mechanism switch.
