Embodiment
To combine accompanying drawing below, so that the utility model embodiment is done further detailed description.
Please consult Fig. 1, Fig. 2 and Fig. 3 together, the utility model embodiment provides a kind of arrangement on watt-hour meter for avoiding fraudulent use 100, and this arrangement on watt-hour meter for avoiding fraudulent use 100 can be used for preventing that watt-hour meter (Fig. 1, Fig. 2 illustrate side, the front view of this Watt hour meter shell 200 respectively) is by stealing.This Watt hour meter shell 200 comprises base 11 and the anti-electricity-theft device 100 that engages with this base 11; Usually has a circuit board (not shown) that is positioned on its madial wall on the base 11; The microswitch 80 that electrically connects with this circuit board is set on this circuit board; Particularly, this circuit board can be set to a flexible circuit board (pcb board) usually, and this microswitch 80 has a pressure handle 88.
See also Fig. 3, this arrangement on watt-hour meter for avoiding fraudulent use 100 comprises a loam cake 10, end cap 30, flexible member 50, a trigger unit 70 and a button 90.This base 11 engages with loam cake 10 through securing member.
These loam cake 10 relative both sides have one first side 10A (for example lateral surface) and one second side 10B (for example medial surface); In the present embodiment; This loam cake 10 has first receiving space 12 that is opened on the 10A of this first side; In addition, an end of these loam cake 10 contiguous these end caps 30 is offered an accepting groove 14, and this accepting groove 14 has a central shaft M.
These end cap 30 relative both sides have an end face 30A and one the 3rd side 30B, and in the present embodiment, this end cap 30 has second receiving space 32 that is opened on the 3rd side 30B.In addition, has a bottom surface 302 that deviates from this end face 30A in second receiving space 32 of this end cap 30.
In the present embodiment, this end cap 30 also has a junction surface 38 that engages with this loam cake 10, and this end cap 30 is through these loam cake 10 settings relatively slidably of this junction surface 38.This end cap 30 can combine or separate with this loam cake 10.
This flexible member 50 is arranged in this accepting groove 14, and in the present embodiment, this flexible member 50 can be a spring.
Please further consult Fig. 4 to Fig. 8, this trigger unit 70 comprises a sleeve part 72 and a trigger part 74.This trigger part 74 is extended out by the lateral surface of this sleeve part 72; In the present embodiment; As shown in Figure 5; This trigger part 74 can be
shape; In other change embodiment; This trigger part 74 can be
shape, or is in-line.Be not limited to specific embodiment.
This button 90 is connected to this sleeve part 72; In the present embodiment, as shown in Figure 5, this button 90 comprises a head 92 and a coupling shaft 94 that is extended out by this head 92; This head 92 is positioned at this accepting groove 14, and this coupling shaft 94 is extended in this sleeve part 72 by this accepting groove 14.Particularly, this head 92 and these coupling shaft 94 coaxial settings, and the central shaft M of this button 90 is roughly parallel to the composition surface 380 at this junction surface 38, and in addition, the central shaft M of this button 90 overlaps with the central shaft N of this accepting groove 14.In the present embodiment, these flexible member 50 sheathed these coupling shafts 94 are positioned at the part of this accepting groove 14, and these sleeve part 72 sheathed these coupling shafts 94 extend the remainder of this accepting groove 14.
Thereby this sleeve part 72 is connected with this coupling shaft 94 through being set on this coupling shaft 94 mutually.In the present embodiment, as shown in Figure 8, have grab 720 in this sleeve part 72, offer draw-in groove 940 on the lateral surface of this coupling shaft 94, this sleeve part 72 is connected with this coupling shaft 94 with the cooperation of this draw-in groove 940 through this grab 720.
In the present embodiment, said flexible member 50, trigger unit 70 and button 90 mutually combine and form by the extend out structure of similar semi-girder of this end cap 30.
In addition; Like Fig. 7 and shown in Figure 8, in the present embodiment, offer a shoulder hole 740 in the end of these sleeve part 72 contiguous these buttons 90; At this shoulder hole 740 O-ring seal 86 is set; Sealing circle 86 is set on this coupling shaft 94 and seals, and for example can play waterproof action, prevents promptly that water droplet from leaking to cause the circuit board short circuit on the circuit board.
This head 92 is resisted against between the bottom surface 302 of this flexible member 50 and this end cap 30; In the present embodiment; Can offer an in-line draw-in groove (not shown) on the end face of this head 92; Can further extend on the bottom surface 302 of this end cap 30 one with the suitable muscle 39 (seeing also Fig. 3) of this draw-in groove, this muscle 39 can be fastened in this draw-in groove, so that this button 90 interconnects with this end cap 30.It is understandable that head 92 and this muscle 39 of this button 90 can be interfered the formation interference fit each other, to guarantee to have when pushing stroke.In other change embodiment, this muscle 39 and this in-line draw-in groove also can be set, directly the head 92 with button 90 is resisted against on this bottom surface 302.One side of these end cap 30 relative these bottom surfaces 302 has a press surface that is used to push (for example in the zone of outside surface over against head 92).In addition, it is tabular that this muscle 39 can be not limited to the rectangle shown in the figure, for example can be other shapes such as column.
Please consult Fig. 2 again; During installation; This arrangement on watt-hour meter for avoiding fraudulent use 100 can be installed in the sidewall of this Watt hour meter shell 200, makes contiguous this circuit board of the second side 10B of loam cake 10, and this moment, these trigger part 74 contiguous these circuit boards were provided with (trigger part 74 is isolated with the microswitch 80 on the circuit board).
When electricity filching person did not carry out stealing, this end cap 30 combined with this loam cake 10, receives the elastic force effect of this flexible member 50, and trigger part 74 contacts with microswitch 80 on the circuit board.When electricity filching person carries out stealing; It must open this end cap 30 along direction S with finger; At this moment; The head 92 of this button 90 receives this flexible member 50 of tension pulling of this muscle 39 (being the bottom surface 302 of end cap 30 when muscle is not set), and drives the side shifting of the coupling shaft 94 of this button 90 to contiguous this end face 30A.It is understandable that because grab 720 matches with this draw-in groove 940, this coupling shaft 94 will drive this trigger unit 70 and move away from this microswitch 80.When this trigger part 74 when microswitch 80 on this circuit board breaks off mutually, the supervising device that is connected with this microswitch 80 is opened like camera, can monitor the electricity filching behavior of electricity filching person through supervising device, in addition, this moment, pressure handle 88 was in not contact condition.
Because the microswitch 80 and the button 90 of the described arrangement on watt-hour meter for avoiding fraudulent use 100 of the utility model are separately positioned on first receiving space 12 and 14 li of accepting grooves; The central shaft N that this microswitch 80 departs from this accepting groove 14 (also is the central shaft M of button 90; Central shaft M overlaps with central shaft N); First receiving space 12 and accepting groove 14 that mutual isolation can be provided thus are to accommodate microswitch 80 and button 90 respectively; Make button 90 and microswitch 80 disalignments can prevent that thus pressure is applied directly to microswitch 80 and causes microswitch 80 because of the excessive damage that causes of exerting pressure, make these arrangement on watt-hour meter for avoiding fraudulent use 100 durables.
In addition, those skilled in the art also can do other variation in the utility model spirit, and certainly, these all should be included within the utility model scope required for protection according to the variation that the utility model spirit is done.
