Embodiment
Execution mode below in conjunction with accompanying drawing is explained in detail the preferred embodiments of the present invention:
As shown in Figure 2, the present invention is a kind of signal Surge Protector, and it is by being made of the circuit board 1 with discharge circuit, shell 2, circuit board installing rack 3 and pin 4.The circuit board 1 that wherein has discharge circuit is installed on the circuit board installing rack 3, described shell 2 is enclosed within outside the described circuit board installing rack 3, have an observation panel 21 at the top of shell 2, before this signal Surge Protector is threaded off, can observe the color of mobile indicator board 53 from this observation panel; After dropout, can observe the color of mobile indicator board installing rack 51 from observation panel.Shell 2 and circuit board installing rack are all made with high-temperature flame-retardant plastic, pin 4 is welded on the circuit board 1 with discharge circuit, be welded with divider resistance R1, R2, gas discharge tube G, Transient Suppression Diode T, switching diode D1, D2, D3, D4 and some leads at the circuit board 1 with discharge circuit, they constitute a signal surge discharge circuit together, and the electrical schematic diagram of this signal surge discharge circuit as shown in Figure 1.Wherein, Transient Suppression Diode T is as parts of heat dropout indicating mechanism 5, an one pin T1 directly is welded on the circuit board 1 with discharge circuit, and another pin T2 is connected on the circuit board 1 with discharge circuit by the miscellaneous part of heat dropout indicating mechanism 5.Described hot dropout indicating mechanism 5 is made up of Transient Suppression Diode T, mobile indicator board installing rack 51, metal-coating 52, mobile indicator board 53, extension spring 54 and flexible conductor 55, wherein, mobile indicator board installing rack 51 usefulness high-temperature flame-retardant plastics are made, it is installed on the circuit board installing rack 3, is positioned at the top of the circuit board 1 with discharge circuit, and is provided with twice groove 511 at the upper surface of mobile indicator board installing rack 51.Metal-coating 52 is wrapped in the outer surface of described Transient Suppression Diode T, and inserts in the mobile indicator board installing rack 51 after another pin T2 welding of Transient Suppression Diode T, at metal-coating 52 projection 521 is arranged.Mobile indicator board 53 usefulness pcb boards are made, and it is movably arranged in the groove 511 on the upper surface of mobile indicator board installing rack 51, and can slide at the effect hypopharynx groove 511 of extension spring 54.Have the hole 531 of a thin-and-long in the central authorities of mobile indicator board 53 along long side direction, be provided with metal level 532 on the surface of mobile indicator board 53 1 ends; In the described protruding 521 thin-and-long holes of stretching on the mobile indicator board 53 531, and connect with metal level 532 usefulness eutectic welding solderings on the mobile indicator board 53; Extension spring 54 is fixed between mobile indicator board 53 and the mobile indicator board installing rack 51 with being in extended state, and the one end is fixed on the mobile indicator board 53, and the other end is fixed on the mobile indicator board installing rack 51.Flexible conductor 55 1 ends are welded on the metal level 532 of mobile indicator board 53, and the other end is welded on the circuit board 1 with discharge circuit; The color of mobile indicator board installing rack 51 and mobile indicator board 53 is inequality, and wherein, mobile indicator board installing rack 51 is red, and mobile indicator board 53 is green.
The principle of hot dropout of the present invention indicating mechanism is: as shown in Figure 2; when signal Surge Protector operate as normal is; metal level 532 on a pin T1, the Transient Suppression Diode T of bottom electronic circuit by Transient Suppression Diode 7, metal-coating 52, the mobile indicator board 53 and flexible conductor 55 constitute a loop and carry out operate as normal; at this moment, the observation panel 21 from the product casing 2 is seen is green mobile indicator board 53.
After the signal Surge Protector is aging; the surface temperature of Transient Suppression Diode T will raise; because the heat transfer effect of metal-coating 52; the low temperature scolding tin temperature of the metal level 532 of the projection 521 of weld metal overcoat 52 and mobile indicator board 53 is also raise; after reaching uniform temperature; to cause the low temperature melts soldering tin; under the pulling force effect of extension spring 54; mobile indicator board 53 is pulled; be the projection 521 and mobile indicator board 53 disengagings on the metal-coating 52; thereby cut off aging circuit, made the signal Surge Protector be in the pass-through state of not working, guaranteed the work of original signal line.Because mobile indicator board 53 is different with the color of mobile indicator board installing rack 51; and mobile indicator board installing rack 51 does not block owing to having had mobile indicator board 53 after threading off; so; the color for mobile indicator board installing rack 51 that observation panel 21 on shell 2 is seen is namely red; this signal Surge Protector of surface aging dropout thus, thus reach aging indicative function.
