Description

[Technical Field]

[0001] The present invention relates to a switching device, and more particularly to a switching device having graphene copper contact points and adapted for high current applications. [Background technology]

[0002] Conventional switching devices, such as electronic switches, semiconductor switches, high-voltage and high-current terminals, and relays, generate sparks at their contact points every time they are switched. Copper contact points can melt and fuse together after repeated switching over a long period of time. Summary of the Invention [Problem to be solved by the invention]

[0003] Although silver contacts have high heat resistance and a long product life, all-silver contacts are very expensive and have a clearly low cost-performance ratio. To save costs, most conventional contact structures use a base metal (such as copper) body coated with a precious metal layer, so that when the precious metal layer wears out and the switch device needs to be replaced, only the base metal needs to be discarded. However, due to the limitations of conventional materials, contacts coated with a precious metal layer are still unable to handle large currents and are difficult to improve.

[0004] Therefore, the present inventors believed that the above drawbacks could be improved, and after extensive research, they came up with the proposal of the switch device of the present invention, which effectively improves the above problems through a rational design.

[0005] The main purpose of the present invention is to provide a switch device with graphene copper alloy contact points to solve the above problems. [Means for solving the problem]

The second conductor is mounted on the trigger assembly and electrically connected to the second pin, the second conductor having a second contact portion. The second conductor can be moved by the trigger assembly so that the second contact portion contacts the first contact portion of the first conductor. The first and second contact portions are made of a graphene copper alloy, which includes at least graphene and copper.

[0013] In order to solve the above-mentioned problems, another aspect of the present invention provides a switch device comprising a device body, a trigger assembly, a pair of first conductors, and a second conductor.

[0027] The detailed description and technical contents of the present invention will be explained in conjunction with the drawings, but the attached drawings are used for explanation purposes only and are not intended to limit the present invention.

[0028] (First Example) FIG. 1 is a perspective view of a switch device according to a first embodiment of the present invention. FIG. 2 is a partially enlarged view of the switch device according to the first embodiment of the present invention. The switch device according to the first embodiment of the present invention includes a device body 100, a trigger assembly 200, and a plurality of conductors. In this embodiment, the plurality of conductors includes a first conductor 410 and a second conductor 420.

[0029] The device body 100 includes an insulating base 110 and a housing 120. The insulating base 110 has a pin side 111 and a component side 112. A first pin 310 and a second pin 320 are provided on the insulating base 110. Specifically, the first pin 310 and the second pin 320 are inserted into the insulating base 110 to engage with it, but the present invention is not limited thereto. For example, the first pin 310 and the second pin 320 may be fitted into the insulating base 110 by an overmolding method. In this embodiment, the first pin 310 and the second pin 320 are both elongated metal plates that pass through the insulating base 110 and protrude from the pin side 111 and the component side 112, respectively, for insertion into an applicable device.

[0030] The trigger assembly 200 is installed in the device body 100, and in this embodiment, the trigger assembly 200 is installed on the insulating base 110 of the device body 100. Specifically, the trigger assembly 200 includes a resilient arm 210 and an electromagnet 220, and at least a portion of the resilient arm 210 is made of a magnetically permeable material (e.g., iron). In this embodiment, the resilient arm is a combined member in which an iron member is riveted to a phosphor copper member, but the present invention is not limited thereto. The resilient arm 210 is disposed on the element side 112, and the electromagnet 220 is disposed on the element side 112 so as to correspond to the resilient arm 210 and is also disposed on the phosphor copper member. When the electromagnet 220 is driven to generate a magnetic force, the magnetic force of the electromagnet 220 moves (e.g., attracts) the iron member of the resilient arm 210, causing the resilient arm 210 to swing.

[0031] As shown in FIG. 2 , the first conductor 410 is installed in the device body 100 and electrically connected to the first pin 310, and the second conductor 420 is installed in the trigger assembly 200. In this embodiment, the first conductor 410 and the second conductor 420 may be the same component. FIG. 3 is a schematic diagram of a conductor of a switch device according to an embodiment of the present invention. As shown in FIG. 3 , in this embodiment, the first conductor 410 includes a first conductor 411 and a first contact portion 412 of the first conductor 411. Specifically, the first conductor 411 has a nail shape, and the first contact portion 412 is disposed at one end of the first conductor 411. In this embodiment, the first contact portion 412 covers the nail head of the first conductor 411. However, the present invention is not limited thereto. For example, the first contact portion 412 may be inserted into the first conductor 411. Also, for example, the first conductor 410 may be integrally formed with the first contact portion 412 using the same material, or may not have the first conductor 411. In this embodiment, the second conductor 420 has the second conductor 421 and the second contact portion 422. Specifically, the second conductor 421 is nail-shaped, the second contact portion 422 is disposed at one end of the second conductor 421, and the second contact portion 422 in this embodiment covers the nail head of the second conductor 421, but the present invention is not limited thereto. For example, the second contact portion 422 may be fitted into the second conductor 421. Also, for example, the second conductor 420 may be integrally formed with the second contact portion 422 using the same material, or may not have the second conductor 421.

[0032] 1 and 2, in this embodiment, the first conductor 411 is riveted to the first pin 310 and is disposed on the element side 112 of the insulating base 110 of the device body 100. The second conductor 420 is installed in the trigger assembly 200 and is electrically connected to the second pin 320. In this embodiment, the second conductor 421 is riveted to the elastic arm 210 of the trigger assembly 200 and is disposed on the element side 112 of the insulating base 110 of the device body 100. The second contact portion 422 of the second conductor 420 is disposed toward the first contact portion 412 of the first conductor 410. In a predetermined state, the first conductor 410 and the second conductor 420 are disposed separately.

[0033] When the resilient arm 210 of the trigger assembly 200 is moved to swing by the electromagnet 220, the second conductor 420 is moved by the swing of the resilient arm 210, and the second conductor 420 contacts the first contact portion 412 of the first conductor 410 via the second contact portion 422. In this manner, the first pin 310 is electrically connected to the second pin 320. Therefore, the switch device according to this embodiment can switch between opening and closing the circuit to which the first pin 310 and the second pin 320 are connected.

[0034] The first conductor 411 and the second conductor 421 are both made of copper, and the first contact portion 412 and the second contact portion 422 are both made of a graphene-copper alloy. The graphene-copper alloy contains at least graphene (less than 5% by weight) and copper. The graphene-copper alloy is manufactured based on the improved method for metal graphene disclosed in Taiwan Patent Application Publication No. TWI710522. The graphene-copper alloy is sintered at a processing temperature above 1000°C, which breaks the bonds of the graphene and bonds them to copper atoms. Therefore, the graphene-copper alloy has a melting point above 1000°C, can withstand high temperatures, and the graphene has good electrical conductivity. Taking the first conductor 411 as an example, the copper in the graphene-copper alloy of the first contact portion 412 is well bonded to the copper first conductor 411, thereby reducing the electrical resistance between the first conductor 411 and the first contact portion 412 and improving the electrical conductivity of the first conductor 410.

[0035] In this embodiment, the surfaces of the first contact portion 412 and the second contact portion 422 are both flat, and when the first contact portion 412 contacts the second contact portion 422, the surfaces of the first contact portion 412 and the second contact portion 422 are stuck to each other, but the present invention is not limited thereto.

[0036] 4 is a schematic diagram showing a conductor of a switch device according to another embodiment of the present invention. Specifically, the first contact portion 412 has a first convex surface 413, and the second contact portion 422 has a second convex surface 423. In this embodiment, the first convex surface 413 and the second convex surface 423 both have an arc-shaped surface. After several uses, the convex surfaces wear out and deform into a shape that is suitable for being attached to the surface of the second contact portion 422, thereby reducing the electrical resistance between them.

[0037] 5 is a schematic diagram of a conductor of a switch device according to yet another embodiment of the present invention. Specifically, the first contact portion 412 has a first convex surface 413, and the second contact portion 422 has a second convex surface 423. In this embodiment, the first convex surface 413 and the second convex surface 423 are both conical surfaces.

[0038] In this embodiment, the first conductor 410 and the second conductor 420 may be the same structural component. However, depending on different needs, the first conductor 410 and the second conductor 420 may be different structural components. For example, in the structures shown in Figures 3 to 5, the first conductor 410 and the second conductor 420 are installed to be compatible with each other.

[0039] (Second Example) Fig. 6 is an external perspective view of a switch device according to a second embodiment of the present invention. Fig. 7 is a partially enlarged view of the switch device according to the second embodiment of the present invention. The switch device according to the second embodiment of the present invention comprises a device body 100, a trigger assembly 200, and a plurality of conductors. In this embodiment, the plurality of conductors includes a pair of first conductors 410 / 410a and a second conductor 420.

[0040] The device main body 100 includes an insulating base 110 and a housing 120. The insulating base 110 has a pin side 111 and an element side 112. A pair of first pins 310 / 310a and second pins 320 are installed on the insulating base 110. In this embodiment, the first pins 310 / 310a and second pins 320 are both elongated metal plates, and the first pins 310 / 310a and second pins 320 penetrate the insulating base 110 and protrude from the pin side 111 and element side 112, respectively.

[0041] The trigger assembly 200 is installed in the device body 100, and in this embodiment, the trigger assembly 200 is installed on the insulating base 110 of the device body 100. Specifically, the trigger assembly 200 includes a resilient arm 210 and an electromagnet 220, and at least a portion of the resilient arm 210 is made of a magnetically permeable material (e.g., iron). In this embodiment, the resilient arm is a combined member in which an iron member is riveted to a phosphor copper member, but the present invention is not limited thereto. The resilient arm 210 is disposed on the element side 112, and the electromagnet 220 is disposed on the element side 112 so as to correspond to the resilient arm 210 and is also disposed on the phosphor copper member. When the electromagnet 220 is driven to generate a magnetic force, the magnetic force of the electromagnet 220 moves (e.g., attracts) the iron member of the resilient arm 210, causing the resilient arm 210 to swing.

[0042] 6 and 7, the pair of first conductors 410 / 410a are mounted on the device body 100 and electrically connected to the first pins 310 / 310a, respectively, and the second conductor 420 is mounted on the trigger assembly 200. In this embodiment, the pair of first conductors 410 may be the same member, as shown in FIG. 3, but the present invention is not limited thereto. In the structure shown in FIGS. 4 and 5, the first contact portion 412 has a first convex surface 413, and the second contact portion 422 has a second convex surface 423. In this embodiment, the first convex surface 413 and the second convex surface 423 may be arcuate surfaces as shown in FIG. 4 or conical surfaces as shown in FIG. 5.

[0043] According to different needs, the pair of first conductors 410 and second conductors 420 may be different in structure, for example, in the structure shown in Figures 3 to 5, the two are installed to be compatible with each other.

[0044] Each first conductor 410 / 410a shown in this embodiment includes a first conductor 411 / 411a and a first contact portion 412 / 412a. Specifically, the first conductor 411 / 411a is nail-shaped, and the first contact portion 412 / 412a is disposed at one end of the first conductor 411 / 411a. In this embodiment, the first contact portion 412 / 412a covers the nail head of the first conductor 411 / 411a, but the present invention is not limited thereto. For example, the first contact portion 412 / 412a may be inserted into the first conductor 411 / 411a. Furthermore, for example, the first conductor 410 / 410a may be integrally formed with the first contact portion 412 / 412a using the same material, and may not include the first conductor 411 / 411a.

[0045] FIG. 8 is a schematic diagram showing a second conductor 420 of a switch device according to a second embodiment of the present invention. As shown in FIG. 8, in this embodiment, the second conductor 420 includes a second conductor 421 and a pair of second contact portions 422 / 422a. Specifically, the second conductor 421 is nail-shaped, and the pair of second contact portions 422 / 422a are disposed at both ends of the second conductor 421. In this embodiment, the second contact portions 422 / 422a cover both ends of the second conductor 421, but the present invention is not limited thereto. For example, the second contact portions 422 / 422a may be inserted into the second conductor 421. Furthermore, for example, the second conductor 420 may be integral with the second contact portions 422 / 422a using the same material, and may not include the second conductor 421.

[0046] 6 and 7, each of the first conductors 411 / 411a is riveted to a corresponding one of the first pins 310 / 310a and is disposed on the element side 112 of the insulating base 110 of the device body 100, with the pair of first contact portions 412 / 412a of each of the pair of first conductors 410 / 410a being disposed opposite each other. The second conductor 420 is installed in the trigger assembly 200 and is electrically connected to the second pin 320. In this embodiment, the second conductor 421 is riveted to the elastic arm 210 of the trigger assembly 200 and is disposed on the element side 112 of the insulating base 110 of the device body 100. The second conductor 420 is arranged between the pair of first conductors 410 / 410a, the pair of second contact portions 422 / 422a of the second conductor 420 are arranged back-to-back to correspond to each first conductor 410 / 410a, and the second conductor 420 can be moved by the trigger assembly 200 so that one second contact portion 422 (422a) contacts the first contact portion 412 (412a) of the corresponding first conductor 410 (410a).

[0047] In a predetermined state, the second conductor 420 is preloaded onto one of the first conductors 410a by the trigger assembly 200, and the second conductor 420 contacts the first contact portion 412a of the preloaded first conductor 410a via one of the second contact portions 422a, thereby electrically connecting the first pin 310a connected to the first conductor 410a to the second pin 320. When the elastic arm 210 of the trigger assembly 200 is moved to swing by the electromagnet 220, the second conductor 420 is moved by the swing of the elastic arm 210, and the second conductor 420 contacts the first contact portion 412 of the other first conductor 410 via the other second contact portion 422, thereby electrically connecting the other first pin 310 to the second pin 320. In this way, the switch device according to this embodiment can switch between two circuits connected to each of the first pins 310.

[0048] 7 and 8, in this embodiment, the surfaces of the first contact portion 412 / 412a and the second contact portion 422 / 422a are both flat. When the first contact portion 412 (412a) contacts the second contact portion 422 (422a), the surfaces of the first contact portion 412 (412a) and the second contact portion 422 (422a) stick to each other, but the present invention is not limited to this. FIG. 9 is a schematic diagram showing a second conductor 420 of a switch device according to another embodiment of the present invention. As shown in FIG. 9, specifically, each second contact portion 422 / 422a has a second convex surface 423 / 423a, and in this embodiment, the second convex surfaces 423 / 423a both have an arcuate surface.

[0049] 10, the switch device of the present invention may include a conductor 400 entirely made of graphene copper alloy, with at least one contact portion 401 / 401a formed at an appropriate position on the conductor 400. The conductor 400 can be adapted to be the first conductor 410 / 410a or the second conductor 420 / 420a in the embodiments shown in the previous figures based on different positions, and any one of the contact portions 401 / 401a can be adapted to be the first contact portion 412 / 412a or the second contact portion 422 / 422a in the embodiments shown in the previous figures when arranged at a corresponding position.

[0050] The first contact portion 412 / 412a and the second contact portion 422 / 422a of the switch device of the present invention are made of graphene copper alloy, which has good electrical conductivity, a melting point of over 1000°C, heat resistance, and low wear.

As shown in Fig. 11 and 11C, following step b, in step c, the second mold 12 is closed on the first mold 11 to form a conductor 400, and the contact point portion 41 is formed by the second mold 12 to form a contact portion 401, and the first mold 11 is formed to form another contact portion 401a. In this embodiment, to manufacture a nail-shaped conductor, the inner contour of the first mold 11 is tubular and the inner contour of the second mold 12 is arc-shaped concave, but the present invention is not limited thereto. Specifically, the second mold 12 is closed onto the first mold 11, and the contact point portion 400 is molded by the first mold 11 and the second mold 12 to form the conductor 400, and the contours within the molds of the first mold 11 and the second mold 12 correspond to the predetermined outer shape of the contact portion 401 (401a), and either end of the contact point portion is molded by the first mold 11 and the second mold 12 to form the contact portion 401 (401a).

[0055] When the graphene copper alloy is annealed, its hardness ranges from 80HV to 150HV (HV, Vickers hardness), which is higher than that of copper, and this hardness range can tolerate deformation caused by repeated collisions of the contact portion 401 (401a). Therefore, the contact points can be dispersed so that wear of the contact portion 401 (401a) is not concentrated in a certain area.

[0056] 11 and 11D, following step c, in step d, the conductor 400 is subjected to a heat treatment (heating time is in the range of 60 to 90 minutes, holding temperature is in the range of 350 to 550°C, and holding time is in the range of 60 to 90 minutes, and after holding, the conductor 400 is left to stand and annealed). Following step d, in step e, the conductor 400 that has undergone the heat treatment is washed.

[0057] (Fourth Example) 12A to 12D are schematic diagrams illustrating steps in a method for manufacturing a conductor for a switch device according to a fourth embodiment of the present invention. Referring to FIGS. 12A to 12D, in this embodiment, a conductor 400 is manufactured and used as the first conductor 410 or the second conductor 420 in the embodiment shown in FIG. 3. The steps of this embodiment are described below.

[0058] 11 and 12A, first, in step a, a first mold 11, a second mold 12, and a contact point portion 41 are provided. In this embodiment, the contact point portion 41 is made of the graphene copper alloy. In this embodiment, a conductive portion 42 is further provided. In this embodiment, the conductive portion 42 is made of copper and is softer than the contact point portion 41 made of the graphene copper alloy.

[0059] 11 and 12B , following step a, in step b1, the conductive portion 42 is first inserted into the first mold 11 before the contact point portion 41. Following step b1, in step b, the contact point portion 41 is inserted into the first mold 11 and pressed to fit into one end of the conductive portion 42. Specifically, by abutting the contact point portion 41 against the one end of the conductive portion 42, the conductive portion 42 is pressed into the first mold 11, and the conductive portion 42 is pressed at the same time, so that the contact point portion 41 fits into the one end of the conductive portion 42. In this embodiment, the diameter of the contact point portion 41 is smaller than that of the conductive portion 42 and the hardness of the contact point portion 41 is higher than that of the conductive portion 42, making it easier for the contact point portion 41 to fit into the conductive portion 42.

[0060] 11 and 12C, following step b, in step c, the second mold 12 is closed onto the first mold 11 to form the conductor 400, and the contact point portion 41 is shaped by the second mold 12 to form the contact portion 401. When the second mold 12 is closed onto the first mold 11, the contact point portion 41 and the conductive portion 42 are compressed by the first mold 11 and the second mold 12. In this embodiment, to manufacture a nail-shaped conductor, the inner contour of the first mold 11 is tubular, and the inner contour of the second mold 12 is arc-shaped concave, but the present invention is not limited thereto. Specifically, the second mold 12 is closed to the first mold 11, and the conductive portion 42 is molded by the first mold 11 and the second mold 12 to form the conductor 402, and the contour inside the second mold 12 corresponds to the specified external shape of the contact portion 401, so that the contact point portion 41 can be molded by the second mold 12 to form the contact portion 401.

[0061] After annealing, the graphene copper alloy has a hardness range of 80HV to 150HV (HV, Vickers hardness), which is higher than that of copper, and this hardness range allows for deformation caused by repeated collisions of the contact portion 401. Therefore, the contact points can be dispersed so that wear of the contact portion 401 is not concentrated in a certain area.

[0062] 11 and 12D, following step c, in step d, the conductor 400 is subjected to heat treatment (heating time is in the range of 60 to 90 minutes, holding temperature is in the range of 350 to 550°C, and holding time is in the range of 60 to 90 minutes, and after holding, the conductor 400 is left to stand and annealed). Following step d, in step e, the conductor 400 that has undergone heat treatment is washed.

[0063] (Fifth Example) 13A to 13D are schematic diagrams illustrating steps in a method for manufacturing a conductor for a switch device according to a fifth embodiment of the present invention. Referring to FIGS. 13A to 13D, in this embodiment, a conductor 400 is manufactured and used as the second conductor 420 / 420a in the embodiment shown in FIG. 8. The steps of this embodiment are described below.

[0064] 11 and 13A, in step a, the present embodiment first provides a first mold 11 and a second mold 12. Similarly to the contact point portion 41 and the other contact point portion 41a made of the same material, in this embodiment, each contact point portion 41 and 41a is made of the graphene copper alloy. In this embodiment, the conductive portion 42 is made of copper and is softer than the contact point portions 41 and 41a made of the graphene copper alloy.

[0065] 11 and 13B, following step a, in step b2, first, the one contact point portion 41a is inserted into the first mold 11. Following step b2, in step b1, the conductive portion 42 is then inserted into the first mold 11. Following step b1, in step b, the other contact point portion 41a is inserted into the first mold 11. Specifically, the two contact point portions 41 and 41a are pressed in advance so as to fit onto both ends of the conductive portion 42, and then inserted into the first mold, and the first contact point portion 41 behind the conductive portion 42 and the contact point portion 41a in front of the conductive portion 42 are pressed into the first mold 11 and simultaneously pressed to fit together. In this embodiment, the diameter of each contact point portion 41 and 41a is smaller than that of the conductive portion 42, and the hardness of the contact point portions 41 and 41a is higher than that of the conductive portion 42, making it easier for the contact point portions 41 and 41a to fit into the conductive portion 42.

[0066] 11 and 13C, following step b, in step c, when the second mold 12 is closed onto the first mold 11, the contact points 41 and 41a are pressed against the conductive portion 42 to form the conductor 400. The contact points 41 form the contact portion 401, the conductive portion 42 forms the conductor 402, and the other contact points 41a form the other contact portion 401a. In this embodiment, to manufacture the nail-shaped conductor 401, the inner contour of the first mold 11 is tubular and the inner contour of the second mold 12 is arc-shaped concave, but the present invention is not limited thereto. Specifically, by closing the second mold 12 to the first mold 41, the conductive portion 42 is molded by the first mold 11 and the second mold 12 to form the conductor 402, and the contour inside the second mold 12 corresponds to the predetermined outer shape of the contact portion 401, so that the first mold 11 and the second mold 12 mold a pair of contact point portions 41 and 41a to form the contact portions 401 and 401a, respectively.

[0067] 11 and 13D, in step d following step c, the conductor 400 is subjected to a heat treatment (heating time is 90 minutes, the holding temperature is in the range of 350 to 550°C, and the holding time is 90 minutes, after which the conductor 400 is left to stand and annealed). In step e following step d, the conductor 400 that has undergone the heat treatment is washed.

[0068] After annealing the graphene copper alloy, its hardness ranges from 80HV to 150HV (HV, Vickers hardness), which is higher than that of copper, and this hardness range allows deformation caused by repeated collisions of the contact portion 401 (401a), so that the contact points can be dispersed to prevent wear of the contact portion 401 (401a) from concentrating in a certain area.

[0069] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
