Abstract
Toroidal magnetic loop cover includes following parts: cylinder connected to the cover in use for fixing insertion piece of left and right toroidal magnetic loop; four pieces of blind hole at bottom end of the cover in use for placing test pins and neutral pins for toroidal magnetic loop. Characters are that there are three pieces of through holes at bottom end of the cover in use for fixing pins of micro switch. Passing through holes, pins of micro switch can be welded on underside of circuit board. Conversion between reset control loop and test control loop is realized expediently through on/off of micro switch. Tight fit adopted between pin and through hole is capable for fixing pins. Features are: simple structure, clever conception.
Description
Technical field:
The present invention relates to a kind of magnetic loop cover that is used for ground-fault interrupter (GFCI), relate in particular to a kind of magnetic loop cover with fixing hole having pins of micro switch.
Background technology:
At present; it is to place neutral misconnection ground protection coil and magnetic test coil in magnetic loop cover that magnetic loop cover in the known ground-fault interrupter (GFCI) mainly acts on; by magnetic loop cover coil and other parts are insulated; open pin holes on the magnetic loop cover; be used to install contact pin, and utilize contact pin that magnetic loop cover is fixed on the printed substrate.The present invention is at magnetic loop cover pin holes one end, open 3 through holes respectively, three pins of sensitive switch are fixed on the printed substrate by through hole, closure by sensitive switch, realize connecting reset control loop and the conversion of testing control loop easily, owing to adopt tight fit between pin and the through hole, can also play fixedly pin effect, simple in structure.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly can effectively overcome above-mentioned defective, realize being connected of pin and printed substrate by fixing hole, and utilize tight fit between pin and the through hole, play the magnetic loop cover of the band fixing hole having pins of micro switch of fixedly pin effect.
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is, a kind of magnetic loop cover with fixing hole having pins of micro switch, mainly comprise: the cylinder and the magnetic loop cover that are used for fixing left and right sides magnet ring inserted sheet link into an integrated entity, the bottom of magnetic loop cover has 4 to be used to put the blind hole that detects magnet ring contact pin and neutral magnet ring contact pin, it is characterized in that: 3 fixing through holes that are used for the sensitive switch pin are arranged in the bottom of magnetic loop cover, the sensitive switch pin can pass through hole, is welded on the bottom surface of wiring board.Owing to adopt such scheme, be not difficult to draw the present invention and have following beneficial effect, the present invention is simple in structure, be skillfully constructed, three pins of sensitive switch be fixed on the printed substrate, by through hole by the closure of sensitive switch, realize connecting reset control loop and the conversion of testing control loop easily, owing to adopt tight fit between pin and the through hole, can also play fixedly pin effect, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is the upward view of the magnetic loop cover of band fixing hole having pins of micro switch of the present invention;
Fig. 2 is the stereogram of sensitive switch.
Embodiment:
Fig. 1 is the upward view of the magnetic loop cover of band fixing hole having pins of micro switch of the present invention.The cylinder 2 that fuses with magnetic loop cover, be used for fixing left and right sides magnet ring inserted sheet, 4 blind holes 3 are arranged in the bottom of magnetic loop cover, be used to put magnetic test coil contact pin and neutral coil contact pin, 3 through holes 4 are arranged in the bottom of magnetic loop cover, be used for the fixing of sensitive switch pin, the sensitive switch pin can pass through hole, is welded on the bottom surface of wiring board.
Fig. 2 is the stereogram of sensitive switch.As Fig. 2-a, the depression bar 1D on the sensitive switch is connected with testing button is flexible, and 3 pins are arranged under the sensitive switch, promptly public pin 1A, normally closed pin 1B, one often open pin C, its three pins become a shape side by side through special back, pass magnetic loop cover, weld in the circuit board, as Fig. 2-b.Special sensitive switch has two effects in control circuit, one is the occlusion detection loop, produces a simulated failure electric current; Turn-off the control loop that resets when also having an effect to be the occlusion detection loop.
Claims (2)
1, a kind of magnetic loop cover with fixing hole having pins of micro switch, mainly comprise: the cylinder (2) that is used for fixing left and right sides magnet ring inserted sheet links into an integrated entity with magnetic loop cover, the bottom of magnetic loop cover has 4 to be used to put the blind hole (3) that detects magnet ring contact pin and neutral magnet ring contact pin, it is characterized in that: 3 fixing through holes (4) that are used for the sensitive switch pin are arranged in the bottom of magnetic loop cover, the sensitive switch pin can pass through hole, is welded on the bottom surface of wiring board.
2, according to the magnetic loop cover of the described band sensitive switch of claim contact pin fixing hole, it is characterized in that: 3 pins of described sensitive switch (1) are respectively public pin C (1A), and normally closed pin NC (1B) often opens pin NO (1C).Wherein public pin and normally closed pin link to each other with the control loop that resets on the circuit, and public pin and Chang Kai pin then link to each other with test control loop on the circuit.
