Technical field of electric appliances, the magnetictrip that a kind of pcb board is mounted directly.
[background technology]
The switching device of protected class have an electrical apparatus release, the quality of electrical apparatus release directly influences protection class switch
Reliability and stability.The device for switching such as existing earth leakage circuit-breaker, movable earth leakage protection socket, leakage protecting plug
Electrical apparatus release, due to reasons such as the heaviest, volume is relatively big, structure complexity, is all separately installed, then, is connected by two lead-in wires
On the pcb board of control unit.The most thus easily cause the phenomenons such as lead-in wire disconnection, make the acting characteristic of device for switching be subject to
The potential safety hazards such as impact, not even action；Have a strong impact on product quality.
[utility model content]
The electromagnetic trip that the purpose of this utility model seeks to solve above-mentioned deficiency and provides a kind of pcb board to be mounted directly
Device.Its volume is little, efficiency is high, the reliability of action when can be effectively improved stability, reliability and the low-voltage of protection switch.
Design the magnetictrip that a kind of pcb board is mounted directly for achieving the above object, including pcb board 1, fixed core 3, move
Iron core 6, spring 8, coil rack 7 and the tripping coil 5 being wound on coil rack, the bottom of described coil rack 7 is built-in with U-shaped
Policy 4, described pcb board 1 is provided with policy hole 11 with the U-shaped corresponding position of policy 4, and described U-shaped policy 4 passes policy hole 11,
And it being welded to connect pcb board 1, the bottom center position of described coil rack 7 is provided with dovetail groove 9 and central through hole 10, described trapezoidal
Being provided with fixed core 3 in groove 9, described fixed core 3 front end is positioned at central through hole 10, and is cased with spring 8, described spring 8 other end
Be connected dynamic iron core 6.
Described fixed core 3 is the T-type structure that big front end, rear end is little.
The bottom of described coil rack 7 is provided with protruding 2, and described pcb board 1 is provided with hole, location with protruding 2 corresponding positions
12, described protruding 2 are positioned at hole 12, location.
This utility model is compared with the existing technology, compact conformation, simple, reasonable in design, can be effectively improved earth leakage protective and open
Close stability and reliability, more can be effectively improved the earth leakage circuit-breaker acting characteristic when low-voltage, be worthy of popularization.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model；
Fig. 2 is axonometric chart of the present utility model.
In figure: 1 is pcb board, 2 is protruding, and 3 is fixed core, and 4 is U-shaped policy, and 5 is tripping coil, and 6 is dynamic iron core, and 7 are
Coil rack, 8 is spring, and 9 is dovetail groove, through hole centered by 10, and 11 is policy hole, and 12 is hole, location.
[detailed description of the invention]
Below in conjunction with the accompanying drawings this utility model is made further explained below:
As shown in drawings, this utility model includes: pcb board 1, fixed core 3, dynamic unshakable in one's determination 6, spring 8, coil rack 7 and around
Tripping coil 5 on coil rack, the bottom of described coil rack 7 is built-in with U-shaped policy 4, with U-shaped side on described pcb board 1
The corresponding position of pin 4 is provided with policy hole 11, and described U-shaped policy 4 is through policy hole 11, and is welded to connect pcb board 1.Described U-shaped side
Pin 4 is formed by two, and is embedded in respectively in coil rack 7, and the most U-shaped policy 4 is the most highly stable and firm.Described
The bottom center position of coil rack 7 is provided with dovetail groove 9 and central through hole 10, is provided with fixed core 3 in described dovetail groove 9, described
Fixed core 3 front end is positioned at central through hole 10, and is cased with spring 8, and described spring 8 other end is connected and moves unshakable in one's determination 6.
Further, described fixed core 3 is the T-type structure that big front end, rear end is little.Described fixed core is positioned at coil rack
Bottom, and be fixed in dovetail groove 9, between the little head part of fixed core and dynamic unshakable in one's determination 6, leave one section of space, be used for placing
Spring.On the one hand this structure can make the position of spring stablize, and on the other hand can reduce the distance between dynamic and static iron core,
Effectively improve the electromagnetic property within coil rack.The loosening spring that affects preventing fixed core normally works and uses the longevity
Life.
Further, the bottom of described coil rack 7 is provided with two circular projections 2, with protruding 2 phases on described pcb board 1
The position answered is provided with hole 12, location, and described protruding 2 are positioned at hole 12, location.The two projection can play coil rack 7 at PCB
Positioning action on plate, convenient in product installation.
This utility model is not limited by above-mentioned embodiment, other any real without departing from spirit of the present utility model
The change made under matter and principle, modify, substitute, combine, simplify, all should be the substitute mode of equivalence, be included in this practicality
