Outer casing inner wall is equipped with an embedding hole to match with capacitance, and capacitive head is all located in embedding hole；Above the embedding hole covered with positioned at
The explosive portion of outer surface of outer cover；Explosive portion's thickness is less than outer casing thickness；The explosive portion upper surface center is equipped with one
Explosive slot, explosive slot are externally provided with several extension slots being circularly and evenly distributed, and extension slot connects with explosive slot.
The outer surface of outer cover is equipped with a protection step, and explosive portion is arranged in protection step；The protection step wall surface will
Explosive portion surrounds.
The outer casing inner wall is equipped with a protection block；The protection block thickness is more than outer casing thickness, and embedding hole is arranged in protection block.
The beneficial effects of the utility model are：
Compared with prior art, when being brought into operation using the new converter of the utility model structure, transformer generates magnetic
The line of force, at this time shielded coil formed annular wire winding, the magnetic line of force can be lockked, the magnetic line of force is made to lock in transformer, will not
There is the situation of magnetic line of force sinuous flow, effectively prevent cutting magnetic line movement, enable electronic component normal operation, ensure conversion
Device normal operation, so that interior electrical installation normal operation, prevents electrical installation failure, effectively avoid accidents, make
The personal safety of driving personnel is protected.
Compared with prior art, the cutting on capacitive head can be passed through using the new converter of the utility model structure
The explosive force that explosive slot on slot and explosive portion can occur capacitance with extension slot is concentrated to explosive portion position, in explosive force
When obtaining leading off by explosive portion, it can ensure that explosive force will not be acted on to entire shell, therefore shell is not in be fried
Winged situation, so as to ensure will not to be damaged to driving personnel in explosion time shell.
Description of the drawings
Fig. 1 is the structure diagram of an angle of the new converter of the utility model；
Fig. 2 is the structure diagram of another angle of the new converter of the utility model.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments：
It please refers to Fig.1, Fig. 2, the utility model provides a kind of new converter, including shell 1, the electricity in shell 1
Road plate 2 and the transformer 3 on circuit board 2, the transformer 3 are wound with shielded coil 4 outside；It is set on the circuit board 2
There is the capacitance 5 of several adjacent distributions；5 top of the capacitance is equipped with several cutting grooves 6, in 5 top center of capacitance between cutting groove 6
Position crosses one another；1 inner wall of shell is equipped with an embedding hole 7 to match with capacitance 5, and 5 top of capacitance is all located in embedding hole 7；
7 top of embedding hole is covered with positioned at the explosive portion 8 of 1 outer surface of shell；8 thickness of explosive portion is less than 1 thickness of shell；It is described
Explosive 8 upper surface center of portion is equipped with an explosive slot 9, and explosive slot 9 is externally provided with several extension slots 10 being circularly and evenly distributed,
Extension slot 10 connects with explosive slot 9.
1 outer surface of shell is equipped with a protection step 11, and explosive portion 8 is arranged in protection step 11；The protection step
11 wall surfaces surround explosive portion 8.
1 inner wall of shell is equipped with a protection block 12；12 thickness of the protection block is more than 1 thickness of shell, and embedding hole 7, which is arranged on, to be protected
In protecting block 12.
The application method of the utility model is as follows：
When converter brings into operation, transformer 3 generates the magnetic line of force, and shielded coil 4 forms the wire winding of annular at this time,
The magnetic line of force can be lockked, the magnetic line of force is made to lock in transformer 3, is not in the situation of magnetic line of force sinuous flow, effectively prevents cutting
The magnetic line of force moves, and enables electronic component normal operation, ensures converter normal operation, so that interior headlight, steering indicating light, brake
The electrical installations normal operation such as car light, loudspeaker prevents converter failure, effectively avoids accidents, make the people of driving personnel
Safety is guaranteed for body.
When capacitance 5 because explosion time occur in some reasons, since the top of capacitance 5 is equipped with several cutting grooves 6, cutting groove 6 it
Between cross one another in 5 top center of capacitance, therefore 5 top skin intensity of capacitance is more weak, 5 top center of capacitance
Intensity it is then the weakest, when 5 inside of capacitance starts explosion time, explosive force then can actively be led off towards weak spot, last capacitance 5
Interior explosion can then be concentrated towards capacitive head direction, and when explosion occurs from 5 top of capacitance, explosive force can then be locked in embedding hole
It in 7, and continues towards 1 outside of shell along the direction that capacitance 5 explodes and occurs, and be covered in 8 thickness of explosive portion of embedding 7 top of hole
Far smaller than 1 thickness of shell, therefore 8 position of explosive portion is point most weak on shell 1, once exploding, explosion site is only
Explosive 8 position of portion can be concentrated on, in the case of having explosive slot 9 on explosive 8 surface of portion, the intensity in explosive portion 8 is cut again
It is weak, and extension slot 10 can then expand weakening scope, it can be ensured that explosion betides explosive 8 position of portion, equally but ensures explosive portion 8
The release of explosive force is completed with enough scopes, in a manner that explosive force is led in explosive portion 8 off explosive force is made not act on
Onto entire shell 1, therefore shell 1 is not in situation about being blown up, so as to which ensure will not be to driving people in explosion time shell
Member damages.
1 outer surface of shell is equipped with protection step 11, and explosive portion 8 is arranged in protection step 11, and 11 wall surface of protection step will be easy
Quick-fried portion 8 surrounds, protection step 11 presence can make explosion be happened at shell 1 it is outer when, explosive range then can be by protection step 11
Wall surface limitation, even if explosion is happened at outside shell 1, also the same control is in explosive 8 peripheral extent of portion, so as to confining blast model
It encloses, ensures that explosion will not damage driving personnel to the full extent.
1 inner wall of shell is equipped with protection block 12, and 12 thickness of protection block is more than 1 thickness of shell, and embedding hole 7 is arranged in protection block 12,
The presence of protection block 12 can form apparent thickness difference with explosive portion 8, can enhance the intensity of shell 1, ensure that shell 1 will not be by
Explosive force influence is chipping, can also be further ensured that explosion occurs towards explosive 8 position of portion.
