Description
Technical field
The utility model belongs to the surge protector with indicating structure, specifically a kind of surge protector with indicating structure.
Background technology
Surge protector is also known as lightning arrester or Surge Protector, be called for short (SPD) to be applicable to exchange 50/60HZ, in rated voltage to the electric power system or communication system of 380V, under normal circumstances, it is in high impedance status, and once circuit because surge appears in thunderbolt or other reason, its meeting conducting within the extremely short time, lightning current or overvoltage are introduced the earth by earth connection, carrys out the equipment on protection circuit with this; Existing surge protector comprises housing, be positioned at the rotor plate of housing, one side surface of housing offers through hole, a part for rotatable lamella can be seen from through hole, the surface of the corresponding through hole of rotor plate scribbles different colors, the change of color can be observed when rotor plate moves plate from through hole, thus judge whether to change surge protector; Existing this structure is assembled after being made by the rotor plate of oiling color in manufacturing process again, if but staff forgotten to tint and directly entered rotor plate assembling just cannot play the effect of instruction; And due to rotor plate adopt be plastic material, and the piezo-resistance in surge protector be can generate heat may cause the damage of rotor plate and cause rotor plate cannot play the effect of instruction.
Summary of the invention
The utility model have employed following technical scheme: a kind of surge protector with indicating structure, comprises housing; Wherein, described housing offers sliding tray, the first chamber, the second chamber; Sliding tray is positioned at the top of the first chamber and one end and the second chamber; The two side of described sliding tray offers through hole and groove respectively, and described through hole is corresponding with the position of groove; Be provided with fixing indicating piece in groove, be provided with movable indicating piece in sliding tray, under conventional sense, fixing indicating piece covers by movable indicating piece; Movable indicating piece one end is stretched in the second chamber, and described second chamber interior is provided with the pulling mechanism that one end is connected with movable indicating piece; Housing is provided with piezo-resistance, safety plate and trip gear, safety plate is that soldering is connected with a pin of piezo-resistance, and trip gear is connected with one end of safety plate; Movable indicating piece has a projection and safety plate offsets; During soldering fusing, trip gear pulls safety plate to move down, and movable indicating piece pulls by pulling mechanism thus fixing indicating piece spills from through hole.
Adopt said structure, when fusing occurs in soldering, utilize a pulling mechanism direct pull movable indicating piece that fixing indicating piece is exposed from through hole and be convenient to staff's observation; With of the prior art directly a side surface of rotor plate is coated different colours to be rotated by rotor plate realize color switching compared with there is Stability Analysis of Structures indicating structure can not be caused because temperature is too high to lose efficacy.
Wherein, described pulling mechanism comprises and is arranged on boss in the second chamber and spring, and boss is positioned at the below of safety plate, and the two ends of spring are connected on boss and movable indicating piece, and spring is in extended state.
Adopt spring as pulling structure, when soldering is melted, the spring state that affranchises then pulls movable indicating piece to move.
Wherein, described boss is cylinder, and the two ends of spring are round, and one end is connected with movable indicating piece, and another side is set on boss.
Wherein, described safety plate has bending part, the projection of movable indicating piece and the inner side of bending part offset.The setting of bending part improves the stability between movable indicating piece and safety plate.
Wherein, described movable indicating piece and fixing indicating piece are epoxy sheet.Epoxy resin heat resistance is comparatively strong, only need by movable indicating piece from fixing indicating piece is coated different color relations and can play indicative function.
Accompanying drawing explanation
Fig. 1 is the vertical view of the internal structure of the utility model specific embodiment.
Fig. 2 is the close-up schematic view in A portion in Fig. 1.
Fig. 3 is the close-up schematic view in B portion in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
As Figure 1-3, a kind of surge protector with indicating structure, this front surface comprising housing is provided with the first chamber 33, second chamber 34, sliding tray 35, and sliding tray 35 is positioned at the top of the first chamber 33 and is communicated with the second chamber 34; The two side of sliding tray 35 offers respectively through hole 341 and groove 342, through hole 341 is corresponding with the position of groove 342; Fixing indicating piece 44 is provided with in groove 342; Movable indicating piece 43 arranges in being slidably arranged in sliding tray 35, and fixing indicating piece 44 is different from the color of movable indicating piece 43; One end of movable indicating piece 43 extend into the second chamber 34 inside; It is that soldering is connected that piezo-resistance 36 is arranged on that the inner and pin of piezo-resistance 36 of the first chamber 33 to extend in the second chamber 34 with a surface of safety plate 37, and safety plate 37 is connected with trip gear, and when soldering is melted, trip gear pulls open safety plate 37; Safety plate 37 have for bending part 371, movable indicating piece 43 has a projection 431 and offsets with the inner side of bending part 371, the front surface of housing is also provided with the cylindrical boss 46 be positioned at immediately below bending part 371, the two ends of spring 41 are circle portion, one of them circle portion is set on boss 46, movable indicating piece 43 is passed in another circle portion, and spring 41 is in extended state; When soldering between safety plate 37 and the pin of piezo-resistance 36 is melted, safety plate 37 is pulled open by trip gear; Movable indicating piece 43 is pulled by spring 41, thus operating personnel can see fixing indicating piece 44 from through hole 341; Kind and the set-up mode of each parts and all identical of the forward and backward surface texture of housing on the forward and backward surface of housing.
