Abstract
The utility model relates to a surge protector with single window state indication. Two independent energy accumulation type bouncing mechanisms are provided in a casing. Each bouncing mechanism includes an ejector rod, an energy storage spring which is sheathed at the bottom of the ejector rod and a U-shape metal plate which is inserted in the cavity of the middle part of the ejector rod. Pins of the two protective set are respectively welded with the two U-shape metal plates. An indication device is arranged at the head of the two ejector rods. The indication device is provided with a hollow cavity which is used to contain the head of the ejector rod and matched with the flange of the outer side of the ejector rod by a lug boss on the two side walls. No matter any one of the protective elements of the utility model is broken or two protective elements are broken, the indicating can be seen from the indication device with single window state indication. The utility model has the advantages of clear and single state indication and simple and skillful structure.
Description
Technical field
The utility model relates to low-voltage electrical apparatus, specifically a kind of surge protector with single Window state indication, and finger contains the surge protector of two surge protection elements in parallel and two groups of energy storage bouncing mechanisms when 18 moduluses especially.
Background technology
The existing surge protector that adopts the carrier state indication of two protection component parallel connections, the state of two protection component is by bouncing mechanism directly outwards output and indication respectively.It makes the client produce query easily: for where when a protection component and two protection component deteriorations, promptly single indication is ejected and two indication while At time of ejects all need be changed the protectors of whole modulus.
Summary of the invention
To be solved in the utility model is the prior art above shortcomings; the surge protector of the single Window state indication of a kind of follow-on band is provided; purpose is when the surge protector protection component is destroyed, by the single timely repair and replacement of indicating reminders user.The technical scheme that addresses the above problem employing is: with the surge protector of single Window state indication, be provided with two independently energy storage type bouncing mechanisms in the shell, described each bouncing mechanism comprises that a push rod, one are sleeved on the energy-stored spring of described push rod bottom and one and are inlaid in the U type sheet metal in the cavities in the described push rod; The pin of described two protected locations is welded on respectively on described two U type sheet metals; Head at described two push rods is provided with an indicating device.Described indicating device is provided with the cavity of ccontaining described push rod head, and matches by the flange of the boss on the two side with the described push rod outside.Described indicating device top is provided with column indication raised line, offers porose with described indication raised line corresponding position on the described shell.
Of the present utility model under following two kinds of situations indicating device all can realize indicating:
One: when having only one of them protection component destroyed; the pad fusing of its pin and U type sheet metal; both connections are disconnected; energy-stored spring releases energy; the push rod of this side moves upward, and drives the resistance that the flange on the push rod that indicating device overcomes its elastic wall boss and opposite side produces and move upward.
Its two: when two protection components are simultaneously destroyed, the pin of this two protection component simultaneously and corresponding U type sheet metal disconnect, two push rods drive indicating device simultaneously and move upward.
This shows, surge protector of the present utility model, whichsoever protection component is destroyed; or two protection components are when all destroyed; all indicate on single window by same indicating device, state is indicated clear and definite single, and simple in structure, ingenious.Because indicating device of the present utility model adopts column indication raised line, when faulty indication, this column bar can pass protector outer casing, also is being easy to observe than distant location.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of indicating device.
Embodiment
With reference to Fig. 1, surge protector with single Window state indication, be provided with two independently energy storage type bouncing mechanisms 8 in the shell 1, described each bouncing mechanism 8 comprises that a push rod 5, one are sleeved on the energy-stored spring 6 of described push rod 5 bottoms and one and are inlaid in the U type sheet metal 3 in the cavities in the described push rod; The pin 4 of described two protected locations is welded on respectively on described two U type sheet metals 3; Head at described two push rods 5 is provided with an indicating device 7.
With reference to Fig. 2, described indicating device 7 is provided with the cavity 10 of ccontaining described push rod head, and matches by the flange 2 of the boss on the two side 12 11 with the described push rod outside, utilizes the elasticity of two side 12 self that both are tightened.Described indicating device 7 tops are provided with column indication raised line 9, offer porose (this place does not cut open among Fig. 1, so fail to show) with described indication raised line 9 corresponding positions on the described shell 1.
When arbitrary protection component is destroyed; its pin 4 was disconnected with connecting of U type sheet metal 3; energy-stored spring 6 push rod 5 that promotes this side that releases energy moves upward; and drive the resistance that indicating device 7 overcomes its elastic wall convex platform 11 and move upward; column indication raised line 9 passes shell 1, shows malfunction.
The utility model is not limited to above-mentioned execution mode; no matter be the surge protector of which kind of type; no matter also do any variation on its shape or the structure, everyly contain two surge protection elements in parallel and two groups of energy storage bouncing mechanisms and one and can realize that the surge protector that two protection component states is carried out the indicating device of single output all drops within the utility model protection range.
