Publication number: 20240112875Abstract: A lightweight industrial fuse has a housing and a conductive fuse. The housing has a first plastic half-housing and a second half-housing combined with each other. The conductive fuse is integrally formed and clamped between the first and second half-housing. The conductive fuse has a fusible body and two intermediary portions disposed within the housing, and two electrode portions exposed from two opposite ends of the housing. Thus, an enclosed accommodation cavity of the housing is defined through the combination of the first and second half-housing. A manufacturing process is simplified, and a manufacturing cost is decreased, and further a weight of the industrial fuse is effectively reduced.Type: ApplicationFiled: November 23, 2022Publication date: April 4, 2024Inventors: Hung-Chih CHIU, Po-Shuo CHIU

Publication number: 20230402243Abstract: The present invention relates to a protection element having a cover. The protection element has a base and a cover. The base has a low melting point alloy layer. The cover has a receiving recess and a guiding passage. The guiding passage corresponds to a melting area of the low melting point alloy layer. The flux is arranged on the accommodating groove of the cover body. When the flux is melted, the flux flows to the guiding passage so that the flux is kept on the melting area of the low melting point alloy layer. Therefore, it is only necessary to place the flux in the receiving recess during manufacture, which can effectively reduce the manufacturing steps and thus reduce the production cost.Type: ApplicationFiled: July 5, 2022Publication date: December 14, 2023Inventors: Hung-Chih CHIU, Po-Shuo CHIU

Patent number: 11721509Abstract: An easy-to-assemble fuse has a fusible body, a socket, and a cover. The fusible body is engaged with the socket. The cover is covered on the socket and the fusible body and is engaged with the socket. By the engagement between the fusible body and the socket and the engagement between the socket and the cover, the fuse achieves the purpose of fast alignment and positioning. The fuse can be quickly assembled during the manufacturing process, thereby simplifying the manufacturing process, and reducing the production cost.Type: GrantFiled: June 15, 2022Date of Patent: August 8, 2023Assignee: CONQUER ELECTRONICS CO., LTD.Inventors: Hung-Chih Chiu, Po-Shuo Chiu

Patent number: 11469069Abstract: An airtight surface mount fuse with a cavity has a housing, a conductive fuse, a cover and an encapsulant. The housing has an opening and an airtight inner space. The fusible element has a part disposed inside of the airtight inner space and another part exposed from the opening. The cover is configured to fit into the opening. The encapsulant encapsulates the housing, the cover and a segment of the exposing part of the fusible element. The other segment of the fusible element is exposed from the encapsulant. The inner space of the housing is encapsulated by the encapsulant and becomes airtight. The fusible element is disposed inside of the airtight inner space to prevent the hazard occurring from arc spark interacting with flammable gases when a fusible body of the fusible element is fused. It also ensures the fusible body is affected by the external environment.Type: GrantFiled: June 29, 2021Date of Patent: October 11, 2022Assignee: CONQUER ELECTRONICS CO., LTD.Inventors: Hung-Chih Chiu, Po-Shuo Chiu

Publication number: 20220293385Abstract: A surface mount fuse has a housing, a conductive fuse and a cover. The housing has an opening and a non-airtight interior space. The conductive fuse is disposed inside the non-airtight interior space. The cover covers the opening. Because the interior space of the housing is a non-airtight interior space and the conductive fuse is disposed inside the non-airtight interior space. The conductive fuse is not encapsulated by the materials with low thermal conductivity to avoid heat accumulation, so the conductive fuse may avoid the aging. Further, the internal atmospheric pressure and the external atmospheric pressure of the housing may be balanced. Therefore, the conductive fuse is not suffered from the pressure caused by the pressure difference between internal and external of the housing so that the reliability of the surface mount fuse is enhanced.Type: ApplicationFiled: June 1, 2021Publication date: September 15, 2022Inventors: Hung-Chih CHIU, Po-Shuo CHIU

Patent number: 11362505Abstract: A protective element has a body, an inner connection layer, an outer connection layer, a heating layer and a low-melting-point alloy layer. The body is made of a single insulation material. The inner and outer connection layers are formed on two upper and lower surfaces of the body. The low-melting-point alloy layer is formed on the upper surface of the body and is electrically connected to the inner connection layer. The heating layer is mounted inside the body and is electrically connected to the low-melting-point alloy layer by the inner connection layer. The outer connection layer is electrically connected to the low-melting-point alloy layer and the heating layer. The outer connection layer is soldered on a power circuit. When the power circuit encounters overcurrent, the heating layer is heated to fuse the low-melting-point alloy layer faster. Thus, power circuit is cut to protect the power circuit.Type: GrantFiled: January 15, 2021Date of Patent: June 14, 2022Assignee: CONQUER ELECTRONICS CO., LTD.Inventors: Hung-Chih Chiu, Po-Shuo Chiu

Publication number: 20210257174Abstract: A chip-type fuse has a substrate. Two pads are disposed over a first side of the substrate. At least one fusible element is disposed over the first side of the substrate and electrically connects to the pads. A protective layer covers the first side of the substrate and the fusible element. The fusible element has a cross-section that is substantially circular, so the time durations for heat conduction from the center to points on the radial edge at the cross-section of the fusible element are almost equal. Thus, the fusible element can be uniformly heated. Therefore, when the circuit is overheated, the blow of the fusible element is uniform, which may effectively interrupt the circuit and protect the circuit.Type: ApplicationFiled: March 6, 2020Publication date: August 19, 2021Inventors: Hung-Chih CHIU, Po-Shuo CHIU

Publication number: 20210210300Abstract: A surface-mount type micro fuse has a fusible element provided in a housing. The fusible element has a fusible body and two intermediary portions connected to both ends of the fusing portion. Two gaps are formed respectively between the fusible body and the intermediary portions. When the fusible element is blown out due to the transient abnormal current, the gaps between the intermediary portions cause a large distance instantaneously to prevent the arc. Then effectively ensure the safety of the use of the overall circuit.Type: ApplicationFiled: February 28, 2020Publication date: July 8, 2021Inventors: Hung-Chih CHIU, Po-Shuo CHIU
