Description

Technical Field

[0001] This application relates to switching devices, and more particularly to a switching device with graphene copper contacts suitable for high current. Background Technology

[0002] Existing switching devices, such as electronic component switches, semiconductor component switches, high-voltage high-current terminals, and relays, generate sparks with each switching contact. Copper contacts are prone to melting and sticking together after repeated switching. While silver contacts are more heat-resistant and have a longer product lifespan, all-silver contacts are expensive, making their economic efficiency clearly poor. To save costs, current contact structures often consist of a base metal (such as copper) covered with a precious metal layer. When the precious metal layer is depleted, replacing the switching device only discards the base metal. However, limited by existing materials, contacts covered with a precious metal layer are still unsuitable for high-current applications and are difficult to improve.

[0003] In view of this, the applicant has devoted himself to studying the aforementioned prior art and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the target of the applicant's improvement. Utility Model Content

[0063] The detailed description and technical content of this application will be explained in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application.

[0064] Figure 1 This is a perspective view of the switching device according to the first embodiment of this application; Figure 2 This is a partial enlarged view of the switching device according to the first embodiment of this application. (See also...) Figure 1 and Figure 2 The first embodiment of this application provides a switching device, which includes a device body 100, a triggering component 200, and a plurality of conductors. In this embodiment, the plurality of conductors includes a first conductor 410 and a second conductor 420.

[0065] 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 fastened to the insulating base 110 by a snap-fit, but this application is not limited to this. For example, the first pin 310 and the second pin 320 can also be embedded in the insulating base 110 by encapsulation injection molding. In this embodiment, the first pin 310 and the second pin 320 are both elongated metal strips, and the first pin 310 and the second pin 320 respectively penetrate the insulating base 110 and protrude from the pin side 111 and the component side 112 for insertion into the device.

[0066] A trigger assembly 200 is disposed on the device body 100. In this embodiment, the trigger assembly 200 is disposed on the insulating base 110 of the device body 100. Specifically, the trigger assembly 200 includes a spring arm 210 and an electromagnet 220. At least a portion of the spring arm 210 is made of a magnetically conductive material (e.g., iron). In this embodiment, the spring arm is an assembly of a phosphor bronze component riveted to an iron component, but this application is not limited to this. The spring arm 210 is disposed on the assembly side 112, and the electromagnet 220 is disposed on the assembly side 112 corresponding to the spring arm 210 and disposed on the phosphor bronze component. When the electromagnet 220 is driven to generate a magnetic force, the electromagnet 220 can move (e.g., attract) the iron component of the spring arm 210 by its magnetic force, causing the spring arm 210 to deflect.

[0067] like Figure 2 As shown, the first conductor 410 is disposed on the device body 100 and electrically connected to the first pin 310, while the second conductor 420 is disposed on the trigger component 200. In this embodiment, the first conductor 410 and the second conductor 420 can be components with the same structure. Figure 3 This is a schematic diagram of the conductors of the switching device of this application. Figure 3 As shown, in this embodiment, the first conductor 410 has a first conductive body 411 and a first contact portion 412. Specifically, the first conductive body 411 is nail-shaped, and the first contact portion 412 is disposed at one end of the first conductive body 411. In this embodiment, the first contact portion 412 covers the nail head of the first conductive body 411, but this application is not limited to this example. For example, the first contact portion 412 can also be embedded in the first conductive body 411. Alternatively, the first conductor 410 can also be integrally formed with the first contact portion 412 of the same material without having a first conductive body 411. In this embodiment, the second conductor 420 has a second conductive body 421 and a second contact portion 422. Specifically, the second conductive body 421 is nail-shaped, and the second contact portion 422 is disposed at one end of the second conductive body 421. In this embodiment, the second contact portion 422 covers the nail head of the second conductive body 421, but this application is not limited to this example. For example, the second contact portion 422 can also be embedded in the second conductive body 421. For example, the second conductor 420 can also be integrally formed from the same material to form the second contact portion 422 without having a second conductive body 421.

[0068] See Figure 1 and Figure 2In this embodiment, the first conductive body 411 is riveted to the first pin 310 and disposed on the assembly side 112 of the insulating base 110 of the device body 100. The second conductor 420 is disposed in the trigger assembly 200 and electrically connected to the second pin 320. In this embodiment, the second conductive body 421 is riveted to the spring arm 210 of the trigger assembly 200 and disposed on the assembly side 112 of the insulating base 110 of the device body 100. The second contact portion 422 of the second conductor 420 is disposed facing the first contact portion 412 of the first conductor 410. In a preset state, the first conductor 410 and the second conductor 420 are disposed separately.

[0069] When the spring arm 210 of the trigger component 200 is deflected by its electromagnet 220, the second conductor 420 is moved due to the deflection of the spring arm 210, and the second conductor 420 contacts the first contact portion 412 of the first conductor 410 with its second contact portion 422, thereby electrically connecting the first pin 310 to the second pin 320. Therefore, the switching device of this embodiment can switch the circuit connected to the first pin 310 and the second pin 320 between open and closed circuits.

[0070] Both the first conductive body 411 and the second conductive body 421 are made of copper, and both the first contact portion 412 and the second contact portion 422 are made of graphene-copper alloy. The graphene-copper alloy contains at least graphene (less than 5% by weight) and copper, and can be prepared according to the graphene modification method for metals described in patent TWI710522. The graphene-copper alloy is sintered at an operating temperature above 1000°C, causing the graphene bonds to break and the copper atoms to connect. Therefore, the graphene-copper alloy has a melting point above 1000°C and can withstand high temperatures, and graphene has excellent electrical conductivity. Taking the first conductive body 411 as an example, the copper in the graphene-copper alloy of the first contact portion 412 can effectively bond with the copper-based first conductive body 411, thus reducing the resistance between the first conductive body 411 and the first contact portion 412 and improving the conductivity of the first conductor 410.

[0071] 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 attached to each other, but this application is not limited thereto.

[0072] Figure 4This is a schematic diagram of another embodiment of the conductor of the switching device according to the first embodiment of this application. 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, both the first convex surface 413 and the second convex surface 423 are arc surfaces. After several uses, the convex surface wears down and deforms, allowing its shape to fit against the surface of the mating second contact portion 422, thereby reducing the resistance between them.

[0073] Figure 5 This is a schematic diagram of another embodiment of the conductor of the switching device according to the first embodiment of this application. Specifically, the first contact portion 412 has a first convex surface 413, and the second contact portion 422 has a second convex surface 423. Moreover, in this embodiment, both the first convex surface 413 and the second convex surface 423 are conical surfaces.

[0074] In this embodiment, the first conductor 410 and the second conductor 420 are components with identical structures. However, depending on different usage requirements, the first conductor 410 and the second conductor 420 can also be components with different structures, for example... Figures 3 to 5 The two components of the structure shown are arranged in combination.

[0075] Figure 6 This is a perspective view of the switching device according to the second embodiment of this application; Figure 7 This is a partial enlarged view of the switching device according to the second embodiment of this application. (See also...) Figure 6 and Figure 7 The second embodiment of this application provides a switching device, which includes a device body 100, a triggering component 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.

[0076] 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, and a pair of first pins 310 / 310a and second pins 320 are provided on the insulating base 110. In this embodiment, the first pins 310 / 310a and the second pins 320 are both elongated metal strips, and the first pins 310 / 310a and the second pins 320 respectively penetrate the insulating base 110 and protrude from the pin side 111 and the component side 112 respectively.

[0077] A trigger assembly 200 is disposed on the device body 100. In this embodiment, the trigger assembly 200 is disposed on the insulating base 110 of the device body 100. Specifically, the trigger assembly 200 includes a spring arm 210 and an electromagnet 220. At least a portion of the spring arm 210 is made of a magnetically conductive material (e.g., iron). In this embodiment, the spring arm is an assembly of a phosphor bronze component riveted to an iron component, but this application is not limited to this. The spring arm 210 is disposed on the assembly side 112, and the electromagnet 220 is disposed on the assembly side 112 corresponding to the spring arm 210 and disposed on the phosphor bronze component. When the electromagnet 220 is driven to generate a magnetic force, the electromagnet 220 can move (e.g., attract) the iron component of the spring arm 210 by its magnetic force, causing the spring arm 210 to deflect.

[0078] like Figure 6 and Figure 7 As shown, the pair of first conductors 410 / 410a are disposed on the device body 100 and electrically connected to each of the first pins 310 / 310a, respectively, while the second conductor 420 is disposed on the trigger component 200. In this embodiment, the pair of first conductors can be components with identical structures, as shown in the diagram. Figure 3 As shown, but this application is not limited thereto, and may also be as shown Figures 4 to 5 The structure shown has a first convex surface 413 on its first contact portion 412 and a second convex surface 423 on its second contact portion 422. Furthermore, in this embodiment, the first convex surface 413 and the second convex surface 423 can be as follows: Figure 4 The curved surface shown or as Figure 5 The cone-shaped surface shown.

[0079] Depending on the specific application requirements, the pair of first body conductors (410, 410a) and the second body conductor 420 can also be components with different structures, for example... Figures 3 to 5 The two components of the structure shown are arranged in combination.

[0080] In each of the first conductors 410 / 410a shown in this embodiment, the first conductor 410 / 410a has a first conductive body 411 / 411a and a first contact portion 412 / 412a. Specifically, the first conductive body 411 / 411a is nail-shaped, and the first contact portion 412 / 412a is disposed at one end of the first conductive body 411 / 411a. In this embodiment, the first contact portion 412 / 412a covers the nail head of the first conductive body 411 / 411a, but this application is not limited thereto. For example, the first contact portion 412 / 412a may also be embedded in the first conductive body 411 / 411a. Alternatively, the first conductor 410 / 410a may also be integrally formed with the same material to form the first contact portion 412 / 412a without having a first conductive body 411 / 411a.

[0081] Figure 8This is a schematic diagram of the second conductor 420 of the switching device according to the second embodiment of this application. (See also...) Figure 8 In this embodiment, the second conductor 420 has a second conductive body 421 and a pair of second contacts 422 / 422a. Specifically, the second conductive body 421 is nail-shaped, and the pair of second contacts 422 / 422a are respectively disposed at both ends of the second conductive body 421. In this embodiment, the second contacts 422 / 422a cover both ends of the second conductive body 421, but this application is not limited thereto. For example, the second contacts 422 / 422a can also be embedded in the second conductive body 421. Alternatively, the second conductor 420 can also be integrally formed of the second contacts 422 / 422a from the same material without having a second conductive body 421.

[0082] See Figure 6 and Figure 7 Each first conductive body 411 / 411a is riveted to its corresponding first pin 310 / 310a and disposed on the assembly side 112 of the insulating base 110 of the device body 100. The pair of first contacts 412 / 412a of the pair of first conductors 410 / 410a are arranged facing each other. A second conductor 420 is disposed in the trigger assembly 200 and electrically connected to the second pin 320. In this embodiment, the second conductive body 421 is riveted to the spring arm 210 of the trigger assembly 200 and disposed on the assembly side 112 of the insulating base 110 of the device body 100. The second conductor 420 is disposed between the pair of first conductors 410 / 410a. The pair of second contacts 422 / 422a of the second conductor 420 are disposed opposite to each of the first conductors 410 / 410a. The second conductor 420 can be moved by the triggering component 200 so that one of the second contacts 422 (422a) contacts the first contact 412 (412a) of the corresponding first conductor 410 (410a).

[0083] In a preset state, the second conductor 420 is pre-pressed by the trigger component 200 onto one of the first conductors 410a. The second conductor 420 contacts the first contact 412a of the pre-pressed first conductor 410a with one of its second contact portions 422a, thereby electrically connecting the first pin 310a connected to the first conductor 410a to the second pin 320. When the spring arm 210 of the trigger component 200 is moved and deflected by its electromagnet 220, the second conductor 420 is moved by the deflection of the spring arm 210, and the second conductor 420 contacts the first contact 412 of the other first conductor 410 with its other second contact portion 422, thereby electrically connecting the other first pin 310 to the second pin 320. Therefore, the switching device of this embodiment can switch between two circuits respectively connected to each of the first pins 310 / 310a.

[0084] See Figure 7 and Figure 8 In this embodiment, the surfaces of the first contact portion 412 / 412a and the second contact portion 422 / 422a are both flat, and 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) adhere to each other, but this application is not limited thereto. Figure 9 This is a schematic diagram of another embodiment of the switching device according to the second embodiment of this application, specifically the second conductor 420. (See also...) Figure 9 Specifically, each of the second contact portions 422 / 422a has a second convex surface 423 / 423a, and in this embodiment, the second convex surface 423 / 423a is an arc surface.

[0085] See Figure 10 The switching device of this application also includes a conductor 400 made entirely of graphene copper alloy. At least one contact portion 401 / 401a is formed at an appropriate position on the conductor 400. This conductor 400 can be used as the first conductor 410 / 410a or the second conductor 420, / 420a in the embodiments shown in the foregoing figures, depending on the configuration position. When any of its contact portions 401 / 401a is configured in the corresponding position, it can also be used as the first contact portion 412 / 412a or the second contact portion 422 / 422a in the embodiments shown in the foregoing figures.

[0086] The switching device of this application has its first contact portion 412 / 412a and second contact portion 422 / 422a made of graphene copper alloy. Graphene copper alloy has good electrical conductivity and a melting point above 1000℃, enabling it to withstand high temperatures and has low loss. Moreover, the price of graphene copper alloy is relatively low compared to precious metals such as silver. Compared to existing silver contact switching devices, the switching device of this application has low resistance, excellent conductivity, high temperature resistance, and long service life. It is not only inexpensive but also performs better than existing technologies.

[0087] Figure 11 For a flowchart of the method for manufacturing the conductor of the switch assembly of this application, please refer to [link / reference]. Figure 11 The conductor manufacturing method of the switching device of this application includes at least the following steps: providing a first mold, a second mold, and a contact segment; inserting the contact segment into the first mold, closing the first mold with the second mold to form a conductor, and shaping the contact segment into a contact portion by the second mold; subjecting the conductor to heat treatment (heating time 60-90 minutes, holding temperature 350-550 degrees, holding time 60-90 minutes followed by static annealing); and cleaning the heat-treated conductor.

[0088] Figures 11A to 11D This is a schematic diagram illustrating the steps of a conductor manufacturing method for a switch assembly according to a third embodiment of this application. (See attached diagram.) Figures 11A to 11D In this embodiment, conductor 400 is manufactured as such Figure 10 The usage of the illustrated embodiment is as follows. The steps of this embodiment are as follows.

[0089] See Figure 11 and Figure 11A First, in step a, a first mold 11, a second mold 12, and a contact line segment 41 are provided.

[0090] See Figure 11 and Figure 11B Following step a, in step b, the contact line segment 41 is threaded into the first mold 11. (See attached text.) Figure 11 and Figure 11C Following step b, in step c, the first mold 11 is closed with the second mold 12 to form the conductor 400, and the contact segment 41 is formed into a contact portion 401 by the second mold 12 and another contact portion 401a by the first mold 11. In this embodiment, to make a nail-shaped conductor, the inner contour of the first mold 11 is tubular and the inner contour of the second mold 12 is concave, but this application is not limited to this. Specifically, the first mold 11 is closed with the second mold 12 so that the contact segment 41 is formed into the conductor 400 by the first mold 11 and the second mold 12, and the inner contours of the first mold 11 and the second mold 12 correspond to the predetermined shape of the contact portion 401 (401a) so that either end of the contact segment 41 can be formed into the contact portion 401 (401a) by the first mold 11 and the second mold 12.

[0091] After annealing, the graphene copper alloy has a hardness range of 80HV to 150HV (HV, Vickers hardness), which is better than that of copper. The hardness range allows the contact part 401 (401a) to undergo a permissible degree of deformation after repeated impacts, thus dispersing the contact points to avoid the wear of the contact part 401 (401a) being concentrated in a local area.

[0092] See Figure 11 and Figure 11D Following step c, in step d, the conductor 400 is subjected to heat treatment (heating time 60-90 minutes, holding temperature 350-550 degrees Celsius, holding time 60-90 minutes followed by static annealing). Following step d, in step e, the heat-treated conductor 400 is cleaned.

[0093] Figures 12A to 12D This is a schematic diagram illustrating the steps of a conductor manufacturing method for a switch assembly according to the fourth embodiment of this application. (See attached diagram.) Figures 12A to 12D In this embodiment, conductor 400 is manufactured as such Figure 3 The first conductor 410 or the second conductor 420 in the illustrated embodiment are used. The steps of this embodiment are as follows.

[0094] See Figure 11 and Figure 12A First, in step a, a first mold 11, a second mold 12, and a contact segment 41 are provided. In this embodiment, the contact segment 41 is a segment made of the aforementioned graphene-copper alloy. In this embodiment, a conductive segment 42 is further provided. The conductive segment 42 shown in this embodiment is a copper segment, which is softer than the contact segment 41 made of graphene-copper alloy.

[0095] See Figure 11 and Figure 12B Following step a, in step b1, the conductive segment 42 is inserted into the first mold 11 before the contact segment 41. Following step b1, in step b, the contact segment 41 is then inserted into the first mold 11, and the contact segment 41 is pressed and embedded into one end of the conductive segment 42. Specifically, the conductive segment 42 can be pushed into the first mold 11 by the contact segment 41 against the end of the conductive segment 42, and the conductive segment 42 can be pressed simultaneously to fit the contact segment 41 into the end of the conductive segment 42. In this embodiment, the wire diameter of the contact segment 41 is smaller than that of the conductive segment 42, and the hardness of the contact segment 41 is greater than that of the conductive segment 42, which facilitates the embedding of the contact segment 41 into the conductive segment 42.

[0096] See Figure 11 and Figure 12C Following step b, in step c, the first mold 11 is closed with the second mold 12 to form the conductor 400, and the contact segment 41 is formed into the contact portion 401 by the second mold 12. When the first mold 11 is closed with the second mold 12, the contact segment 41 and the conductive segment 42 are pressed together by the first mold 11 and the second mold 12. In this embodiment, in order to make a nail-shaped conductor, the inner contour of the first mold 11 is tubular and the inner contour of the second mold 12 is concave, but this application is not limited to this. Specifically, the first mold 11 is closed with the second mold 12 to form the conductive body 402 by the first mold 11 and the second mold 12, and the inner contour of the second mold 12 corresponds to the predetermined shape of the contact portion 401, so that the contact segment 41 can be formed into the contact portion 401 by the second mold 12.

[0097] After annealing, the graphene copper alloy has a hardness range of 80HV to 150HV (HV, Vickers hardness), which is better than that of copper. The hardness range allows the contact part 401 to undergo a permissible degree of deformation after repeated impacts, thus dispersing the contact points to avoid the wear of the contact part 401 being concentrated in a local area.

[0098] See Figure 11 and Figure 12DFollowing step c, in step d, the conductor 400 is subjected to heat treatment (heating time 60-90 minutes, holding temperature 350-550 degrees Celsius, holding time 60-90 minutes followed by static annealing). Following step d, in step e, the heat-treated conductor 400 is cleaned.

[0099] Figures 13A to 13D This is a schematic diagram illustrating the steps of a conductor manufacturing method for a switch assembly according to a fifth embodiment of this application. Referring to 13A to 13D, in this embodiment, conductor 400 is manufactured as such. Figure 8 The second conductor 420 / 420a in the illustrated embodiment is used. The steps of this embodiment are as follows.

[0100] See Figure 11 and Figure 13A In step a of this embodiment, a first mold 11, a second mold 12, a contact segment 41 as described above, and another contact segment 41a of the same material are provided. The contact segments 41 and 41a shown in this embodiment are made of the aforementioned graphene-copper alloy. The conductive segment 42 shown in this embodiment is made of copper, which is softer than the contact segments 41 and 41a made of graphene-copper alloy.

[0101] See Figure 11 and Figure 13B Following step a, in step b2, one of the aforementioned contact segments 41a is first inserted into the first mold 11. Following step b2, in step b1, the conductive segment 42 is then inserted into the first mold 11. Following step b1, in step b, the other contact segment 41a is then inserted into the first mold 11. Specifically, the two contact segments 41 and 41a can be pre-pressed and embedded into both ends of the conductive segment 42 before being inserted into the first mold, or the conductive segment 42 and the preceding contact segment 41a can be pushed into the first mold 11 by the subsequent contact segment 41 and simultaneously pressed and fitted together. In this embodiment, the wire diameter of each contact segment 41 and 41a is smaller than that of the conductive segment 42, and the hardness of the contact segments 41 and 41a is greater than that of the conductive segment 42, which facilitates the embedding of the contact segments 41 and 41a into the conductive segment 42.

[0102] See Figure 11 and Figure 13CFollowing step b, in step c, when the first mold 11 is closed with the second mold 12, each contact segment 41, 41a is pressed and connected to the conductive segment 42 to form a conductor 400. The contact segment 41 forms a contact portion 401, the conductive segment 42 forms a conductive body 402, and another contact segment 41a forms another contact portion 401a. In this embodiment, to produce the nail-shaped conductor 400, the inner contour of the first mold 11 is tubular and the inner contour of the second mold 12 is concave, but this application is not limited to this. Specifically, when the first mold 11 is closed with the second mold 12, the conductive segment 42 is shaped by the first mold 11 and the second mold 12 to form a conductive body 402. The inner contour of the second mold 12 corresponds to the predetermined shape of the contact portion 401, so that each contact segment 41, 41a can be shaped into contact portions 401, 401a by the first mold 11 and the second mold 12 respectively.

[0103] See Figure 11 and Figure 13D Following step c, in step d, the conductor 400 is subjected to heat treatment (heating time 90 minutes, holding temperature 350-550 degrees Celsius, holding time 90 minutes followed by static annealing). Following step d, in step e, the heat-treated conductor 400 is cleaned.

[0104] After annealing, the hardness of the graphene copper alloy ranges from 80HV to 150HV (HV, Vickers hardness), which is better than that of copper. The hardness range allows the contact part 401 (401a) to undergo a permissible degree of deformation after repeated impacts, thus dispersing the contact points to avoid the wear of the contact part 401 (401a) being concentrated in a local area.

[0105] The above description is merely a preferred embodiment of this application and is not intended to limit the patent scope of this application. Other equivalent variations that utilize the patent spirit of this application should all fall within the patent scope of this application.
