Specific embodiment

Refering to Fig. 3 and Fig. 4, one embodiment of invention relay includes 2, bobbin winder bracket lists of a coil unit Member 3 and a yoke unit 4, and be able to cooperate a switch unit (not shown) and carry out control switching, due to the fortune of relay Make mode content known to industry thus, this will not be repeated here.

The bobbin winder bracket unit 3 is isolation material, and the bobbin 31 of the coil unit 2 winding is supplied including one, and respectively Extended outwardly by 31 both ends of bobbin to limit the coil unit 2 first baffle 32 and a second baffle 33.

The yoke unit 4 includes a mandrel 41 for being arranged in the bobbin 31 and a yoke 42, which includes One extends for the substrate 421 of the second baffle 33 setting and an extending direction by 421 lateral margin of substrate along the mandrel 41 Side plate 422, the side plate 422 is adjacent to the lateral margin of the first baffle 32 and the lateral margin of the second baffle 33.

First resistance to indent 321 of the first baffle 32 formation one between the coil unit 2 and the side plate 422, and by It is recessed to form the first resistance to indent 321 towards the plate face of the second baffle 33, which extends to the first baffle 32 adjacent to the side plate 422 outer rim, and run through the first baffle 32 two plate faces.

Second resistance to indent 331 of the second baffle 33 formation one between the coil unit 2 and the side plate 422, and by It is recessed to form the second resistance to indent 331 towards the plate face of the first baffle 32, the depth which is recessed is less than should The thickness of second baffle 33, and the second baffle 33 is extended to adjacent to the outer rim of the side plate 422.

Via above explanation, the advantages of the present embodiment, can be summarized as follows:

One, by the way that the first resistance to indent 321 is arranged, make the coil unit 2 via the first baffle 32 to the yoke 42 Breakdown path, being increased by originally simple " creepage distance " a1+a2 is that " creepage distance " a1 adds " space length " a2, wherein Space length (clearance) refers between two conducting elements or measures between conducting element and object interface via air separation Shortest straight line distance, and creepage distance (creepage distance or creepage distance) refers to that measuring two along insulating surface leads The shortest distance between electric device or between conducting element and object interface, since tolerance level of the space length for voltage breakdown is remote It is substituted by space length a2 greater than creepage distance, therefore by creepage distance a2, can be significantly increased via 32 path of first baffle The withstand voltage value of breakdown, wherein the distance a2 hollowed out can be determined according to actual demand.

Two, by the way that the second resistance to indent 331 is arranged, can increase by the coil unit 2 via the second baffle 33 to this The breakdown path of yoke 42, being increased by creepage distance b is therefore creepage distance b+h can increase via 33 path of the second baffle The withstand voltage value of breakdown, wherein depth h can be determined according to actual demand.

Wherein, since electrically electric current can tend to walk the smallest path of impedance, on 32 path of first baffle And the withstand voltage value on 33 path of second baffle need to arrange in pairs or groups, the withstand voltage value to avoid a wherein side is too small and limits whole The proof voltage degree of body.

Fig. 5~12 are respectively the second~nine pattern of the present embodiment, wherein Fig. 5,7~11 illustrate the second baffle respectively 33 various change, other variations that Fig. 6,12 illustrate the first baffle 32, the difference point of the pattern and above-mentioned first pattern It states as follows:

Be refering to the difference of Fig. 5, second pattern and above-mentioned first pattern: the second resistance to indent 331, which forms to surround, to be somebody's turn to do The ring-type of coil unit 2.This pattern with the effect of above-mentioned first pattern and withstand voltage value is essentially identical.

Be refering to the difference of Fig. 6, the third pattern and above-mentioned first pattern: the first baffle 32 is square, but also It can be rectangle or other shapes.This pattern with the effect of above-mentioned first pattern and withstand voltage value is essentially identical.

Refering to Fig. 7, the difference of the 4th pattern and above-mentioned first pattern is: the second resistance to indent 331 through this second Two plate faces of baffle 33.

Wherein, which is b1+h via the creepage distance of the second baffle 33 to the yoke 42, due to this pattern In, reduce the creepage distance of distance b2, and increase the creepage distance of distance h, therefore be relatively suitble to using thicker (h) this Two baffles 33 promote withstand voltage value to maintain enough creepage distances.

Refering to Fig. 8, the difference of the 5th pattern and the 4th pattern is: the second baffle 33 further includes one by separate The plate face of the first baffle 32 is recessed the extension slot 332 to be formed, which is located between the coil unit 2 and the side plate 422 And it is connected to the second resistance to indent 331.

Wherein, which is b1+h1+b2+h2 via the creepage distance of the second baffle 33 to the yoke 42, by In this pattern, distance b1, b2 is smaller, therefore is relatively suitble to using the second baffle 33 of thicker (h1+h2) to remain enough Creepage distance and promote withstand voltage value.

Refering to Fig. 9, the difference of the 6th pattern and the 5th pattern is: the second resistance to indent 331 and 332 shape of extension slot At the ring-type for surrounding the coil unit 2.This pattern with the effect of five patterns and withstand voltage value is essentially identical.

Refering to fig. 10, the difference of the 7th pattern and the 5th pattern is: the extension slot 332 is extended inwardly to close to should Mandrel 41 increases distance b2 to increase creepage distance and promotes withstand voltage value.

Refering to fig. 11, the difference of the 8th pattern and above-mentioned first pattern is: the second resistance to indent 331 is not extend to this Outer rim of the second baffle 33 adjacent to the side plate 422.

Wherein, which is b1+h+b2+h+b3 via the creepage distance of the second baffle 33 to the yoke 42, is borrowed This, promotes withstand voltage value to increase creepage distance.

Refering to fig. 12, the difference of the 9th pattern and above-mentioned first pattern is: the depth that the first resistance to indent 321 is recessed Less than the thickness of the first baffle 32, and the first baffle 32 is extended to adjacent to the outer rim of the side plate 422.

Wherein, it is a+k which, which is increased via the creepage distance of the first baffle 32 to the yoke 42 by a, because This, can increase the withstand voltage value punctured via 32 path of the first baffle, wherein depth k can be determined according to actual demand.

In this way, the second~nine pattern can also reach purpose identical with above-mentioned first pattern and effect, and can be for making User selects different patterns according to different demands, so can increase using upper flexibility ratio, increases market sale potentiality.

In conclusion so the purpose of the present invention can be reached really.

As described above, only the embodiment of the present invention is when cannot be limited the scope of implementation of the present invention with this, i.e., all According to simple equivalent changes and modifications made by claims of the present invention and description, all still belong to the scope of the present invention.
