Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] Figure 1 to Figure 18As shown, a large current surge protector includes a base 10 and a surge protection module 20. The base 10 is equipped with a first conductive connection terminal 30 and a second conductive connection terminal 40 electrically isolated from each other. The surge protection module 20 is connected to the base 10 in a plug-in manner. In this embodiment, the first conductive connection terminal 30 and the second conductive connection terminal 40 have the same structural size, and their positions can be interchanged.
[0042] The surge protection module 20 includes a bracket 1 and an overvoltage limiting element 2. The bracket 1 is made of plastic material to form an insulator. The bracket 1 can be generally designed in an L shape, and the bracket 1 is equipped with a first conductive contact. 3 and the second ...

The invention discloses a chase-flow surge protector which comprises a base and a surge protecting module inserted in the base. The surge protecting module comprises a support and an overvoltage limit element, a first and second conductive contacts are installed on the support, a first electrode arranged on the overvoltage limit element is fixedly connected with the first conductive contact and is electrically connected with the same, and two second electrodes are arranged on two opposite outer surfaces of the overvoltage limit element; two tripping rotation frames are respectively arranged at the positions close to the two second electrodes, the tripping rotation frames are pivotally connected on the support, an electric piece is installed between each tripping rotation frame and the support, and a conductive piece is fixedly connected to each tripping rotation frame; the second conductive contact is provide with two conduction extension portions; the conductive pieces are respectively adhered to one second electrode and one conductive extension portion through two sides faces and a hot-melt alloy layer; preferentially, the elastic pieces adopt springs. By the arrangement, the chase-flow surge protector can bear larger surge current, compact in structure, small in size and good in maintenance performance.
Description
technical field [0001] The invention relates to a surge protector, in particular to a large current surge protector. Background technique [0002] Surge protector is an overvoltage control device in electronic equipment, also known as "overvoltage protector" in the past. The function of the surge protector is to limit the instantaneous overvoltage that enters the power line and signal transmission line within the voltage range that the equipment or system can withstand, or to leak the powerful lightning current into the ground, so as to protect the protected equipment or system from being damaged. Damaged by impact. [0003] The structure of some existing surge protectors is divided into two parts, one part is the base, and the other part is the surge protection module. The surge protection module and the base realize plug-in connection. There are two electrical contacts on the surge protection module that are in contact with the two wire connection terminals on the base r...
