Abstract
The present invention discloses a manufacturing method of feedback transformer. It comprises a shell body, and the high-voltage capacitor, coils and other rectifying element, etc. received in the shell body. It is characterized by that when the high-voltage capacitor is placed into the shell body, it is not fixed yet into a cylindrical form, and after said all components are placed in the shell body, it is fixed by injecting resin. Said invention only needs once packaging process with resin to make the high-voltage capacitor into the cylindrical form to improve the quality and safety of said product, and shorten its production time and reduce its product cost.
Description
The present invention relates to a kind of manufacture method of reciprocating transformer.
Please refer to shown in Figure 1, in the manufacture method of traditional reciprocating transformer, this reciprocating transformer 1 is to comprise a housing 11, be provided with an accommodation space 12 in this housing 11, make a support body 40 and on high-voltage capacitance 43, coil 41 and other rectifier cell 42 etc. installed just can be placed in this housing 11, in addition, these housing 11 lateral margin appropriate positions also are provided with groove 13, this groove 13 just can make one to adjust button 20 embeddings wherein, after treating that these elements are assembled in the accommodation space 12 of this housing 11, give the sealing location again.
Above-mentioned high-voltage capacitance 43 is to be reeled by several layers of thin dielectric film to be tubular, giving sealing for the first time earlier fixes, and with coil 41, rectifier cell 42 grades together are installed in the housing 11, remake secondary sealing, only, this high-voltage capacitance 43 is after the sealing first time, outside epoxy resin solidifies, its molecule is linked into stable state mutually, when second time sealing, the resins in the former high-voltage capacitance 43 are difficult for being integral the unfixed combination of this kind with the resin-bonded of sealing for the second time, when the atmosphere temperature variation testing, easily cause the interface slit, and the high pressure sneak-out current (creepage current) that produces can make the slit surfaces carbonization, especially the employed resin of twice sealing is not simultaneously, cause carbonization easilier, and the carbonization meeting produces following point:
1, when carbonized path is finished both positive and negative polarity in high-voltage capacitance 43, high-voltage capacitance 43 promptly lost efficacy, when making the mean time to failure, MTTF of speeding to return transformation electricity 1 by no additional high-pressure electric capacity 43 0.5 hundred ten thousand hours are reduced to 0.08 hundred ten thousand hour, quality becomes by conforming with the regulations and does not conform with the regulations, return goods once the client when measuring this shortcoming, can cause by the gross, so the kind problem is to be classified as fatal shortcoming class on the QC project, event must be returned goods by the gross, and causes loss economically.
2, if the high-voltage capacitance that order was lost efficacy 43 continues to use, then high-voltage capacitance 43 can be generated heat because of two interpolars continue discharge along carbonized path, or on fire or blast genetic system etc., and produces safety problem.
In view of this, for improving the shortcoming of above-mentioned traditional reciprocating transformer manufacture method, the inventor is through the permanent research and experiment of making great efforts, and development and Design goes out the manufacture method of reciprocating transformer of the present invention finally.
A purpose of the present invention is the scarce fraud brought at above-mentioned traditional reciprocating transformer manufacture method, and provide a kind of manufacture method of reciprocating transformer, it only must be by sealing step once, can make the high-voltage capacitance sealing become a tubular, and be fixed in the housing with other elements, make and significantly improve quality and the safety problem that traditional reciprocating transformer is produced because of the sealing step of making secondary, and can shorten the time and the cost of its manufacturing.
Another object of the present invention, a kind of manufacture method of reciprocating transformer is being provided, wherein, the employed resin of this sealing is mixed by pure epoxy resin and inorganic matter powder shape inserts, and this inorganic matter powder inserts can be made of compositions such as aluminium oxide or antimony oxide or silica.
For this reason, technical scheme of the present invention is: a kind of manufacture method of reciprocating transformer, be meant that mainly this reciprocating transformer is to include a housing, be provided with an accommodation space in the housing, make a support body and on the high-voltage capacitance installed, coil and other rectifier cell etc. just are placed in the housing, and this high-voltage capacitance is reeled by several layers of thin dielectric film to form, it is characterized in that being: this high-voltage capacitance is in being installed in housing the time, be not give sealing as yet to be fixed into a tubular, and work as high-voltage capacitance, when coil and other rectifier cell are placed in housing, promptly injecting resin gives sealing and fixes, because, the present invention need only be once sealing, can make the high-voltage capacitance sealing become a tubular, and be fixed in the housing with other elements, can significantly improve quality and safety problem that traditional reciprocating transformer is produced because of the sealing step of making secondary, and can shorten the time and the cost of its manufacturing.
This resin is mixed by pure epoxy resin and inorganic matter powder shape inserts.
This inorganic matter powder shape inserts can be made of aluminium oxide.
This inorganic matter powder shape inserts can be made of antimony oxide.
This inorganic matter powder shape inserts can be made of silica.
Because, the present invention need only be once sealing, can make the high-voltage capacitance sealing become a tubular, and be fixed in the housing with other elements, so make and significantly improve quality and the safety problem that traditional reciprocating transformer is produced because of the sealing step of making secondary, and can shorten the time and the cost of its manufacturing.
For enabling to purpose of the present invention, shape constructing apparatus feature and effect thereof, make further understanding and understanding, for the embodiment conjunction with figs., be described in detail as follows now:
The simple declaration of accompanying drawing:
Fig. 1: the part schematic diagram that is reciprocating transformer.
The main element numbering:
1 ... reciprocating transformer 11 ... housing
43 ... high-voltage capacitance 41 ... coil
42 ... rectifier cell 30,31 ... the U sections heart
See also shown in Figure 1, the present invention is a kind of " manufacture method of reciprocating transformer ", this reciprocating transformer 1 is to comprise a housing 11, be provided with an accommodation space 12 in the housing 11, make a support body 40 and on the high-voltage capacitance 43 installed, coil 41 and other rectifier cell 42 etc. just can be placed in this housing 11, in addition, housing 11 lateral margin appropriate positions also are provided with groove 13, this groove 13 just can make an adjustment button 20 be embedded in wherein, outside set terminals 44 then are exposed on this support body 40, these terminals 44 of mat are connected with other interlock circuit, in addition, this reciprocating transformer 1 is provided with one group of U sections heart 30,31, it is to be set in the through hole 45 of this housing 11, and mat one fastener 32 is fixed, make these iron cores 30,31 just run through the central authorities of this coil 41, form a normal path, magnetic field, and the high voltage that coil 41 is produced, then export in the anode button of cathode ray tube of video display by set cable in the high pressure delivery outlet 14 of these housing 11 bottoms.
