Abstract
The utility model discloses an indicating mechanism of a surge protector, which comprises a thermal detaching mechanism, a transparent window arranged on a cover casing and an indicating sheet disposed inside the transparent window. The front end of the indicating sheet is connected with a first spring, and a bayonet arranged at the rear end of the indicating sheet is connected with the thermal detaching mechanism. The thermal detaching mechanism includes a chip electrode and a connecting rod which are connected by soldering, the lower end of the connecting rod is connected with a second spring, and the upper end of the connecting rod is connected with the bayonet of the indicating sheet. The indicating mechanism of a surge protector has the advantages of simple structure, reliable action, and capabilities of promptly indicating failure state of the surge protector and preventing circuit equipment from being damaged due to no protection.
Description
Technical field
The utility model relates to Surge Protector, is specifically related to a kind of Surge Protector that can show and is in the effective status or the indicating mechanism of disarmed state.
Background technology
Surge Protector (SPD) is indispensable a kind of device in the electronic equipment lightning protection; it can be limited in the instantaneous overvoltage of scurrying into power line, signal transmssion line in the voltage range that equipment or system can bear; or powerful lightning current let out the inflow place, protection equipment or system can not be subjected to impact failure.
Surge Protector in use because frequent overvoltage, or service time is long and aging, causes leakage current to continue to increase, non-linear behaviour reduces, the product deterioration, this moment, Surge Protector will persistent fever.For fear of because of the danger of Surge Protector persistent fever initiation fire; it is very necessary that hot releasing mechanism is set in Surge Protector; hot releasing mechanism can in time move circuitry cuts when Surge Protector is overheated; hot releasing mechanism is after action; Surge Protector had also just lost efficacy, and needed in time to change.Because Surge Protector is connected in parallel in the protected circuit and uses; Surge Protector was difficult for being found after losing efficacy; therefore; it also is very necessary that a faulty indication mechanism is set; the product that it can in time point out the user to change damage after Surge Protector lost efficacy is avoided causing damage because of the protective effect inefficacy.
The utility model content
The technical problems to be solved in the utility model provides a kind of indicating mechanism of Surge Protector of simple in structure, reliable in action.
In order to solve the problems of the technologies described above; the utility model adopts following technical scheme: a kind of indicating mechanism of Surge Protector; comprise hot releasing mechanism, be arranged on the transparency window on the case and be positioned at transparency window with indicating piece; the front end of described indicating piece is connected with first spring, and the rear end of indicating piece is provided with a bayonet socket and is connected with described hot releasing mechanism.
Preferably, described hot releasing mechanism comprises chip electrode and connecting rod, is connected by soldering between chip electrode and the connecting rod, and the lower end of connecting rod is connected with second spring, and the upper end of connecting rod is connected with the bayonet socket of indicating piece.
Preferably, described indicating piece is circular arc.
Preferably, described first spring is a stage clip.
Preferably, described second spring is a stage clip.
The beneficial effects of the utility model are: when Surge Protector was working properly, the normal sign on the indicating piece faced transparency window; When the Surge Protector adstante febre, hot releasing mechanism action, the bayonet socket of indicating piece rear end and hot releasing mechanism are thrown off, and to front slide, the inefficacy sign on the indicating piece moves under the transparency window indicating piece under the promotion of first spring, and prompting needs to change Surge Protector.Simple in structure, the reliable in action of the utility model can in time be indicated the failure state of Surge Protector, avoids circuit arrangement to suffer damage because of can not get protection.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the indicating mechanism of the utility model Surge Protector.
Embodiment
As shown in Figure 1, the indicating mechanism of the utility model Surge Protector comprises a case 1, is provided with protection chip and hot releasing mechanism in the case 1.Hot releasing mechanism comprises chip electrode 8 and connecting rod 5, is connected by tin welding spot 6 between chip electrode 8 and the connecting rod 5.
The top of case 1 is provided with a transparency window 3, indicating piece 2 be positioned at case, transparency window 3 below, the front end of indicating piece 2 is provided with a baffle plate 21, be provided with a barricade 11 in the case 1, first spring 4 is compressed between baffle plate 21 and the barricade 11, indicating piece 2 is circular arc and certain elasticity is arranged, and its rear end is sagging along camber line.The rear end of indicating piece 2 is provided with a bayonet socket 22, and bayonet socket 22 is connected with the upper end of the connecting rod 5 of hot releasing mechanism, and the lower end of connecting rod 5 is connected with second spring 7, and second spring 7 also is a stage clip.
Scribble red, green two kinds of colors on the indicating piece 2, in normal operation, green color region faces transparency window.If the heating of protection chip, the temperature of chip electrode 8 is elevated to a certain degree, tin welding spot 6 melted by heat, and connecting rod 5 moves upward under the promotion of second spring 7, breaks away from chip electrode 8, and protection chip and circuit are disconnected, and Surge Protector lost efficacy; Connecting rod 5 promotes the upwards distortion of rear end of indicating piece 2 simultaneously; indicating piece 2 and connecting rod 5 are threaded off, and to front slide, the red color zone on the indicating piece 2 moves to the below of transparency window to indicating piece 2 under the promotion of first spring 4; show redness in transparency window, prompting needs to change Surge Protector.
