Description of the invention (2) Degrees, heat resistance, insulation and other characteristics The main constituent materials are mostly thermosetting resins. For example, for a 30 amp circuit breaker, the crossbar is made of 52% by weight of phenol, 15% by weight of glass fiber, 15% by weight of inorganic filler, 15% by weight of wood flour, 8% by weight of pigment, and other materials. The base is formed by 50% by weight of phenol, 30% by weight of wood flour, 15% by weight of inorganic filler, 5% by weight of pigment, and other materials. Traditional circuit breakers, due to the base that occupies most of the volume of plastic parts, are mostly thermosetting resins such as resins or unsaturated polyacetal resins, which is not conducive to thinning, miniaturizing and lightening parts. In particular, because articles made of thermosetting resin have limitations in forming, each part constituting the interior of the base must have a certain wall thickness regardless of the size of the base. Difficult to make the base smaller. For example, for small circuit breakers below 225 amps, the distance between the poles is below 35mm, the contact pressure between the crimp spring contacts is below 20N, and ribs with a height of 2mm or more must have a wall thickness of 2mm due to restrictions on their forming. Therefore, the parts constituting the interior of the base will exceed a certain wall thickness. Therefore, the wall thickness of the 2mm rib referred to here is a value with adjustment space reserved for determination in accordance with the minimum wall thickness standard of a thermosetting resin which is generally known ^ 3 to 3mm. The base of the conventional circuit breaker is mostly thermosetting resin, so it deforms during molding, and it must be burned or buried when it is ejected when the nozzle or flow channel is generated during molding. In addition, 'requiring extremely high precision for detailed molding, we need to re-examine the molded products containing thermoplastic resins as the main component, especially the molding standards of the base, and the appropriate financial standards [21Q x 297 public [] 312408 (Please (Please read the notes on the back before filling in this page) Decoration nnn -1 ° J · n I n ϋ n ϋ. 494421 Employees of the Intellectual Property Bureau of the Ministry of Economic Affairs and the Twilight Temple of the Opening and Closing Agency Department printed by the agency The standard is applicable to the Chinese National Standard (CNS) A4 specification (21 × 297 mm) 3 A7 B7 V. Description of the invention (3) The thermoplastic resin cannot meet the characteristics required by the base. For example, in JP 08-171847 The molded product containing a thermoplastic resin and an inorganic compound and a reinforcing material that undergo a dehydration reaction at a temperature of 200 ° C or more is shown to be very suitable for circuit breakers because it has good flame resistance and good insulation after the electrodes are opened and closed. Compared with lids, handles, etc., it is a base that is used under high temperature and high pressure, especially when it is more than 100% when it is energized and subjected to strong stress by the crossbar. The over-reduction of creep, deformation, caused by various conditions between the base and the crossbar is greatly reduced, resulting in insufficient phenomena. The inventor, after repeated trial and error, found that a countermeasure can reduce the In order to solve the above-mentioned problem, the purpose of the present invention is to reduce the reduction of the over-travel and reduce the thickness of the base. It is wall-mounted and provides a circuit breaker that is harmless to the environment. [Disclosure of the invention] The present invention relates to a circuit breaker, which is provided with a fixed contact device having a fixed contact, and a sliding contact separated from the fixed contact. The sliding contact device, and the crimp spring that imparts the crimping force between the two contacts when the two contacts are in contact with each other, and an insulating resin as the main material are integrated into $, while maintaining the transmission of the "movable contact device" , The link part connected to the toggle link mechanism is driven by the crossbar around the shaft with the transmission of the toggle link mechanism, and the lever spring is used to take the spring of the toggle link mechanism At the same time, the opening and closing mechanism of the movable contact device is accelerated or decelerated at the same time by the spring, and the fixed support n cover + the cover is formed 312408 ------------- installation -------- order --------- Line (Please read the precautions on the back before filling out this page) 494421 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V.

The thermoplastic resin is at least one of polybutylene terephthalate, polydiphenylsulfite, and a mixture of these materials. Therefore, the dimensional change during moisture absorption is small, and for long-term opening and closing The stability of the generated heat energy is also high. The base contains 55 to 70% by weight of polybutylene terephthalate to which a flame retardant is added and 30 to 45% by weight of a reinforcing material, so that cracks are unlikely to occur when the terminals are tightly tightened. The base contains 40 to 70% by weight of a polyethylene terephthalate to which a flame retardant is added and 30 to 60% by weight of a reinforcing material, and therefore has excellent heat resistance and creep resistance. The base contains 56 to 60% by weight of polyamide containing flame retardant and elastomer, and 40 to 44% by weight of a reinforcing material, so it has good impact resistance and insulation performance after a disconnection.丨 The main component of pine cup is benzene resin, so it not only has good flame resistance but also helps to improve overtravel characteristics. The circuit breaker is multi-pole and has a slit 'on the wall edge orthogonal to the bottom wall of the base, so it can reduce the dimensional change after forming and help reduce the overtravel. The slits divide the orthogonal wall surfaces evenly with an equal thickness, so it can predict the dimensional change after forming and help reduce the overtravel ^ The slits are installed in an intersecting manner from the inside and outside of the base, so it can reduce Dimensional deformation after forming and help reduce overtravel.

Because the wall surface is orthogonal, the contact storage section with the storage movable contact and the fixed contact is the wall surface between the opening and closing mechanism storage section of the opening and closing mechanism section, so the thermal conductivity from the contact side to the switch mechanism side can be reduced. The time delay delays the deterioration of the bone moisturizing agent used in the opening and closing mechanism section and the like because the slits are formed in a cracking manner on the inside and outside of the base, so it can efficiently release heat. Compared with the thickness of the bottom wall of the base, the thickness of the wall surface between the slit and the inside of the base is reduced, which helps to transfer heat energy from the inside of the base to the slit. … The base contains 56 to 60% by weight of polyamines with flame retardants and elastomers and 40 to 44% by weight of reinforcing materials, so it helps to reduce overtravel and achieve thinner and lighter bases Quantification can avoid pollution to the environment.

Description of the Invention (13) 20 is a movable conductor that connects the movable contact device 4 to the overcurrent detection method. Sucked with current: 5 currents. 22 is a conductor to which the overcurrent detection section 21 poles are connected. The terminal board 23 is tightened on the base 1B == fixed ', and the external electric wire magic 25 is tightened with a spring. In addition, the current-carrying circuit in the circuit breaker is composed of fixed contact device 2 contact 3, movable contact 5, movable contact current detection device 21, and conductor = terminal two movable conductors 2. The path through the terminal board 23 is shown. The opening and closing mechanism portion 9 ′ is composed of a toggle link mechanism composed of a lower link n, a link pin 12, an upper link u lever pin u, a control lever 15, a main spring 16, a structure body 17, a handle 19 and the like. . In addition, by operating the handle, the action line 16 of the main spring surpasses the dead point of the toggle link mechanism, and the operation at 0n = the lower toggle link mechanism is rapidly extended, and the converse link mechanism is operated under the ⑽ operation. The movable contact device 4 can be opened and closed freely regardless of the operating speed of the handle 19 because of rapid reduction. In addition, when the overcurrent is disconnected, the latch is released by the disconnection action from the overcurrent detection unit 21, so that the control cup 15 restricted by the latch is no longer restricted by it, and the link pin i5a exceeds the main spring. The action line of 16 and the elbow link device are sharply bent to make the movable contact 5 jump away. -The circuit breaker of the present invention, such as the circuit breaker specified in IEC60947-2, has the functions of quick-on (qUick_make) and quick-off (qUick-break), and at the same time prevents the contacts from melting or opening at the same time.

Explanation of the point of the invention (14) The dotted line shows the closed circuit state, and the solid line shows the The state of the fixed contact device in the closed state and the state of removing the fixed contact device. In the figure, the fixed contact device 2 and the fixed contact device 3 and the movable contact device 4 are removed from the closed circuit state not shown by the dotted line. The spring pin 8 is used to rotate the pivot pin 6 as the center of rotation to the cross bar 7 Zhitie 7a. At this time, the amount of movement of the movable contact is called overtravel. Generally, the overtravel is usually about 1 to 2 times the thickness of the fixed contact 3, which is shown in Fig. 4 as τ. In order to ensure the stability of contact < overtravel ', this overtravel uses repeated opening and closing operations or an arc that is accompanied by opening and closing when energized. Contacts 3 and 5 are worn or worn due to electrical or mechanical reasons or due to both reasons. And in order to reduce the contact bases 1B and the cross bar 7 of the contacts 3 and 5 to deform (especially creep deformation) to ensure the stability of their contact. In addition, a circuit breaker using a conventional base whose main component is a thermosetting resin has a relatively small impact on the overtravel because of the deformation of the latter and the wear of the contact of the former, and the deformation of the latter does not have an effect. Fig. 5 is an explanatory diagram showing an embodiment of the present invention, showing the state of connection between the base of the circuit breaker and the opening and closing mechanism. The opening / closing mechanism 9 is fixed to the base 1B by a spring 18 in the... Structure 17. In addition, the upper link 13 is tied to the // shaft 15a integrally formed in the control lever 15 and the control lever 15 is sufficient to set the integrally formed lever pin 14 as the center of rotation in the structure 17 of the opening and closing mechanism portion 9. The upper link 13 and the lower link n are connected by a link pin 12, and the link pin 12 receives the weight of the main spring 16. In the closed circuit state, the contact pressure is applied by the pressure contact spring 8 between the fixed contact 3 and the movable contact 5. Since the fixed contact device with the fixed contact 3 fixed to the base 1B, a reaction force is generated.

Description of the Invention (I5) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 and the crimping spring 8 'often exerts a load on the crossbar in the direction of arrow A. In addition, the component force of the load A pushes the elbow link mechanism composed of the upper link 13 and the lower link 11 upward by the connecting rod 10, and as a result, 2 15 and the structural body 17 are pushed upward. Therefore, in the closed circuit state, the load E acts upward on the base 1B with the spring insertion portion as the center. Fig. 6 is an explanatory diagram of a contact between a cross bar and a contact as seen from the contact side in the embodiment of the present invention. In the closed circuit state, the load B1 always acts on the center pole of the cross bar 7 due to the action of the pressure contact spring 8. The left and right poles of the cross bar 7 each have a load 32 acting in the upward direction. In addition, the loads from the lower shafts C (shown in Fig. 5) of the rotary shafts 7al, 7a2 of the cross bar 7 often act as the bases lal, la2. In addition, the fixed contact 2 has a downward load D (shown in FIG. 5), and a load E in the upward direction of the structure 17 and the spring 18 acts on the base 1B. In addition, the larger the ampere frame of the circuit breaker, the load of the main spring 16, the load of the fixed crimping spring 8 in the A direction of the crossbar 7, and the direction above the center in the base 1B where the spring 18 is inserted The load e, the loads Bl, B2 of the cross bar 7, the greater the load in the downward direction C from the rotation axes 7al, 7a2 of the cross bar 7. As described above, the pedestal 1B and the cross bar 7 exert a functional load and moment during closed circuit and opening and closing operations. In addition, the dimensional change is caused by the residual stress according to the use temperature of the pedestal 1B or the cross bar 7, The dimensional change caused by moisture absorption, the creep deformation due to temperature, humidity, time, and various composition conditions, but the creep deformation equipment must be inferred due to the different composition conditions -------- order-- ------- Line (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 15 312408 A7 ------- -5. Description of the invention (16) The amount of shape is quite difficult. The creep deformation mainly exerts its effect in the direction of easing stress, that is, in the direction of reducing overtravel. The base 1B with thermoplastic resin as the main component is compared with the base with thermosetting resin as the main component, and a significant reduction in overtravel can be found in the base 1B and the crossbar 7 with the same cultural training range. . For example, Ji Weng Yu, Te Gu Ping No. 08_171847, the reduction of the overtravel of a circuit breaker using a thermoplastic resin as the main component is very significant. When the inventor used a molded product of a base made of a thermoplastic resin, the inventor found that the base 1B and the cross bar 7 having good overtravel characteristics were appropriate and δ. Furthermore, the inventor also found that The relationship between the bending elasticity of 1B and the cross bar 7 under normal temperature and humidity, and the shape of the base 1B are examined. Here, the so-called strange temperature means a temperature between 21 ° C and 25 ° C, and the strange humidity means a humidity between 60% and 70%. The flexural modulus of elasticity under constant temperature and humidity is the measured value (average value) under the environment of humidity between 60% and 70% between 21 ° C and 25 ° C. [Bending elastic modulus of base and cross bar] Base The main component of base 1B is a molded product of the bending elastic modulus of thermoplastic resin under constant temperature and humidity. Examples of the thermoplastic resin include polybutylene terephthalate (PBT), polyethylene terephthalate (pet), polyamide (PA), aliphatic polyketone, and polyphenylene sulfide. Ether (pps) and fusion materials of these. Polyamide, in the chemical structure, has a amine group GCO-NH-), including nylon 6, nylon 66, nylon MXD6, nylon 46, (please read the precautions on the back before filling this page) Binding: Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economics This paper is printed in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 16 312408 A7 A7 Explanation (Π) Nylon 6T and its alloy materials. In addition, polybutylene terephthalate (ρΒΤ), polyethylene terephthalate (PET), polyamide (PA), aliphatic polyketones, polyphenylene sulfide (pps), and others The blended material is crystalline resin. Compared with non-crystalline resins such as polycarbonate (pc), it has the advantages of good chemical resistance and environmental resistance. Therefore, the circuit breaker can be used for a long time in various environments such as oil mist (smoke) environment, ammonia gas environment, and sulfur gas. Polyamide in thermoplastic resin has good impact resistance, and the insulation of the surface of the material is not easily reduced due to the exposure of the arc when the circuit is broken. In addition, in the continuous opening / closing test of repeated energization and interruption of the current, it is more appropriate to choose nylon 66, nylon MXD6, nylon 46, and nylon 6T in terms of shape retention (heat resistance). Consider the angle at which the bending elasticity is not easy to decrease when moisture is absorbed and the size becomes smaller due to moisture absorption. 1Select polybutylene terephthalate (ρΒΤ), polyethylene terephthalate (PET), fat Group polyketones, polyphenylene sulfide (pps) and fusion materials of these are more suitable. In addition, in the above-mentioned permanent opening and closing test, it is appropriate to select polyethylene terephthalate (PET), polyphenylene sulfide (pps), and fusion materials from the perspective of shape retention. -In addition to thermoplastic resins, reinforced materials such as glass fibers and inorganic fillers can be cited, as well as other additives. Crossbar The crossbar is a molded product with a bending elastic modulus Ec under constant temperature and humidity. The main component of this molded product is an insulating resin. At the same time, the same K paper size as the base 1β is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297). 312408 · I ------ ^ --------- (Please read the notes on the back before filling this page) 494421 A7 V. Description of the invention (is) Substances, such as adding unsaturated polyester, phenol resin, etc. (Please read the notes on the back before filling in this page.) Compared with thermoplastic resin or unsaturated polyester, phenol resin not only has good high-temperature spiral deformation characteristics, but also is suitable for injection molding or compression molding. advantage. In addition, phenol-based phenolic resins or soluble phenol-based phenolic resins can also be used, but powder aldehyde-based phenolic resins for lacquers are preferred from the standpoint of dimensional stability of molded products. In addition, the main knife tree & of the cross bar 7 contains wood powder of an organic filler, pulverized cloth, polyamide, polyester, and polypropylene. That is, in this specification, the filler of the cross bar 7 means an inorganic filler, and the organic filler means a filler containing an insulating resin. Inorganic fillers are mainly used to strengthen the strength of molded products and increase the bending elasticity of finished products. In contrast, compared with organic fillers and inorganic fillers, their role is not to improve the bending elasticity of molded products but to improve the molding of molded products. And impact resistance. Examples of components other than the insulating resin include a reinforcing agent such as glass fiber, an inorganic filler, and other additives. The above-mentioned base 1B, the glass fiber of the cross bar 7, the inorganic filler 'and other additives are the following. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The so-called glass fiber means glassy fibrous substances, which are not subject to the total content of metal compounds in Group 1A of the Periodic Table. Examples of the glass material include E glass, S glass, D glass, T glass, and quartz glass. It is generally known that the diameter of the glass fiber is 6 to 13 / xm, and it is preferable to consider the aspect ratio of 10 or more from the viewpoint of improving the impact strength. Inorganic filling materials can include, for example, alumina, calcium carbonate, mica, and the paper size applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) 18 312408 494421 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 5.

Flexural modulus of elasticity The flexural modulus of elasticity Eb of the above-mentioned base and 1B under constant temperature and humidity and the flexural modulus of elasticity Ec of the crossbar 7 under constant temperature and humidity meet the following relationship. In addition, the flexural modulus of elasticity generally decreases as the temperature and humidity increase.

In addition, the cross bar 7 'can be supplied by injection molding or compression molding, but from the viewpoint of high productivity, injection molding is a more ideal choice. When the cross bar 7 is injection-molded, if the bending elasticity 豇 exceeds 17000Mpa, there will be less breakage of the glass fiber in the material mixing process. The length of the particles of the material is too long, and the particles of the material are not easy to fall from the hopper and enter the cylinder. As a result, the material quality of the injection tube is not good, so 17000Mpa is more ideal. As described above, since the main component of the base 1B is a thermoplastic resin, compared with a thermosetting resin, it is less likely to change during molding, and it is also less likely to cause incineration or landfilling such as nozzles or runners during injection molding. Problems such as industrial waste do not cause pollution to the environment. Since the main component of the base 1B is a thermoplastic resin, it is advantageous for resource recovery. In addition, because the main component of the base 1B is a thermoplastic resin, compared with the main component of the base 1B, this resin has good resistance to leakage traces and shortens the insulation distance.

Description of the invention (21) Generate ammonia. In addition, as compared with the base 1B whose unsaturated polyester resin is the main component, the problem of unreacted styrene during use does not occur. Since the main component of the base 1B is a thermoplastic resin, for example, a thin wall design with a wall thickness of 2 mm or less can be formed even with ribs having a height of 2 mm or more. If the thickness can be reduced, the number of ribs or grooves in the same space can be increased, and the insulation distance of the path on the surface of the insulator can be increased. Moreover, the same insulation distance can be ensured in a smaller space, and at the same time, Miniaturization of the product becomes possible. The base 1B whose main component is a thermosetting resin, due to the molding conditions or the physical properties of the material, the insufficient strength of the thin-walled tip due to insufficient filling of the material or insufficient filling of the reinforcing agent such as glass fiber, etc. Because the main component of the base 1B is a thermoplastic resin, the thin-walled tip of the molded product can be solved by filling the material. In addition, since the base 1B is made of a thermoplastic resin as its main component, the weight of the circuit breaker can be reduced. > (Shape of the base) FIG. 7 is a partial cut-away front view of the base of the circuit breaker according to an embodiment of the present invention, FIG. 8 is a rear view, and FIGS. 9 to 11 are The figure is a sectional view taken along the line IX-IX, χ-χ, and χΐ-χι.

Description of the invention (24) Contacts 3, 5 and The wall of the opening and closing mechanism section 9 can prevent the gas from flowing into the opening and closing mechanism section 9 side due to the increase in pressure when the contacts 3 and 5 are disconnected and the fox is turned off. In addition, an opening 42f is provided in the base portion 32h serving as a wall for separating the contacts 3, 5 and the opening and closing mechanism portion 9, because the thermal conductivity of the space (ie, the air layer) of this opening 42f is higher than that of the base portion 42. When it is filled with resin, it is even lower. Therefore, the thermal conductivity of the base 18 from the contacts 3 and 5 to the opening and closing mechanism 9 is relatively low. Therefore, the heat generated at the contacts 3 and 5 is difficult to be transmitted to the opening and closing mechanism portion 9 when the power is turned on, and the deterioration of the lubricant such as oil or butter used in the opening and closing mechanism portion 9 can be delayed. In addition, since the main surface of the back of the base 1B is away from the installation surface of the switchboard by the support protrusion 32, and a slit is installed on the back of the base i B, the heat radiation area becomes larger than when filled with resin. As a result, the heat is more easily dissipated to the outside of the base 1B, so that the deterioration of the lubricating material can be delayed more. In addition, the thickness tO 7 of the wall between the slit 42f and the inside of the base 1B (for example, the slit wall 42 g) is thinner than the thickness t〇6 of the bottom wall 4 2p of the base. Effectively dissipates heat. The partition wall portion 44 is equally divided into the first phase side (the central phase in FIG. 7) and the first phase side (the central phase in FIG. 7) by slits 44a, 44d (especially 44d2) and 44b provided in the extending direction of the partition wall 4i alternately. Phase 2 side (right phase in Figure 7). The slit 44d is composed of spaces 44dl, 44d2, 44d3, and the like. The thickness t10 of the wall 44g between the slit 44d and the space on the side of the trip side 33, and the thicknesses tll, t12, t13 of the walls 44h, 44i, 44j, 44k between the slit 44d and the slits 44a, 44b And t14 are about the same as the thickness t01; the paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 public love) 312408 Ⅲ IIIIII «— III — — — · 11111111 (Please read the precautions on the back before filling (This page) ^ 4421 A7 " ----- ~ __ 5. The thickness of the description of the invention (25). 44x and 44y are convex portions for determining the position, and 44z are convex portions of the spot cover 1A that cooperate with each other. Due to the slits 4 乜 and 44d (especially 44d2), the 44b father is placed on the surface and the back of the base 1B each other. This can make the size of the base 1B more stable after molding, and reduce overtravel. In addition, the thicknesses of the walls 44g, 44h, 44i, 44j, and 44k, t10, tii, t12, t13, and t14, are generally equal, making the dimensions more stable and helping to reduce overtravel. 49A is a slit provided on the surface side of the base 1B and the side wall 30, and 49B and 49C are slits provided on the surface side of the base 1B and the side wall. As described above, the walls 30a, 30d, 36a, 36d, 42b, 42d, 44a, 44b, 44d, 49A, 49B, and 49C are equally divided into predetermined ones by the slits 30a, 30d, 36a, 36d, 49A, 49B, and 49C. Thickness, so that the main component of the thermoplastic resin base β can reduce the number of Zhao Qu or shrinkage depression after molding, and further improve the accuracy of the southern dimension, which helps reduce the number of bases and crossbars 7 and so on. Overtravel caused by warping. Particularly, when a slit is provided in the partition wall 41, the overtravel can be significantly reduced. In addition, the slits on the surface and back of the base 1B in an interactive manner also have a significant effect on reducing the problem of overtravel. In addition, because the walls 36g, 36h, 36i, 36j, 42p, 42q, 44g, 44h, 44i, 44j, etc. forming the slits are generally of uniform thickness, they can be sunken due to warping or shrinkage after forming.

(High-temperature, high-humidity overtravel test) The structure of the circuit breaker shown in Fig. 2 is such that the stress applied to the crossbar 7 in the closed circuit state reduces the effect of the overtravel. The circuit breaker is used for 10 to 15 years. During this period, under high temperature and high humidity conditions in Southeast Asia or inside the road, if the closed circuit state is continuously maintained, when the crossbar 7 or the base 1B with poor overtravel performance is used, the contact pressure between the two contacts It almost disappears and damages the reliability of the power supply. In other words, the creep deformation amount, which is the main factor of overtravel, will not be saturated as long as the stress is added, so the final molded product will be completely destroyed by the creep. Then, the judgment of the overtravel reduction between the base 1B and the cross bar 7 is performed under the following conditions. Using the samples (Π) to (41) of the base and cross bar 7 formed as described above, they were assembled into a circuit breaker (100 amp range) and subjected to a high temperature and high humidity overtravel test. The test is to keep the assembled circuit breaker in a constant temperature and humidity tank at 85 degrees Celsius and 85% relative humidity for one week in the open circuit state. 'The circuit breaker is 40 degrees Celsius and relative humidity at 85 0 / 〇 in the closed circuit state. After being left for 3000 hours in a constant temperature strange wet bath, the over-travel reduction of the movable contact 5 of each pole was measured. From such a measurement result, that is, a measurement result of the overtravel characteristic, an overtravel reduction amount after 15 years is estimated, and based on the thickness of the contact, the reduction amount is a reference value (in the case of the first embodiment, it is determined as follows) (Experimental results) t For this paper butylene glycol dicarboxylate (PBT), polyethylene terephthalate This paper is sized to the Chinese National Standard (CNS) A4 (21 × 297 mm) 312408 (Please (Please read the precautions on the back before filling this page) Γ- 装 &*; * 丁 an in 1§ n ammt mMet i ϋ nn · I 1 29 494421 A7 ------------- B7_ V.

If polyamine (from), 〇, flame retardant accounts for 50 to 70, elastomers account for the proportion. Weight from I to 30. In addition to sample example (33), in addition to the overtravel of the base of the circuit breaker, 1β also has good insulation characteristics after being cut off by electric shock and arcing between contacts. In addition, an elastomer was added to the polyamide of the base 1B of the sample example (33), and the impact resistance was worse than that of the sample example, but the overtravel characteristics were good. In addition, 'polyamine (PA) changes its flexural modulus of elasticity significantly due to humidity.' At room temperature and humidity, the flexural modulus of elasticity Eb tends to be slightly larger than that of other thermoplastic I resins. σ I ------ (Please read the precautions on the back before filling this page).

Description of invention (35) As mentioned above, sample examples (11), (12), (15), (21), (22), (25), (26), (2 8), (29), (3 3), (41 ), That is to say 45 + £ (^ 170001 ^ 0 ^ and 8000MPa $ Eb and 9000MPaSEc, the result of the high temperature and high humidity overtravel test is acceptable. In addition, sample examples (15), (21), (25) When (28), (29), (41), that is, Eb + Ecg 20500MPa and 9000MPaS Eb and 9000MPa SEc, the characteristics of high temperature and high humidity overtravel are better. Moreover, in sample examples (21), (29), and (41), that is, Eb + Ec2 25000MPa and 9000MPaS Eb ′ 22000MPa and 9000MPaS Ec g 17000Mpa, the characteristics of high temperature and high humidity overtravel are very good. In addition, it can be seen from Table 3 that when the main component of the molded product shown is polyamine (PA), warpage and shrinkage of the molded product and dimensional changes due to moisture absorption also promote creep. Deformation reduces the effect of overtravel. Therefore, as the main component of the molded product, in terms of overtravel characteristics, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), Polyphenylene sulfide (PPS) is better. In addition, in order to comply with the base 1B of the circuit breaker, in addition to achieving miniaturization, weight reduction, and no waste during molding, it must have good heat resistance, mechanical strength, impact strength, appearance, flame resistance, and arc disconnection. After the requirements of insulation resistance, leakage traces, and low cost, materials such as polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) are ideal.
