Description
Technical field
The utility model is related to the companies that capacitor area more particularly to capacitor casing draw copper stranded conductor and core lead-out wire
Binding structure.
Background technology
Since the terminals of high-voltage power capacitor are all made of the mode of casing extraction, current many producers sleeve lead-out line
The mode using direct cold weld is connect with core lead, i.e. fuse draws and welds copper stranded conductor in connection sheet, uses Crimping Pliers
In the copper pipe of another long 40mm of side pressure the preceding paragraph of copper stranded conductor, the copper pipe other end crimps the copper stranded conductor of capacitor casing.
This often will appear following some problems in process of production：
1, casing copper stranded conductor is drawn the copper stranded conductor welded in connection sheet with fuse and is coupled by copper pipe transition, needs in copper pipe
Upper crimping 2 times.Artificial crimping loosely causes copper stranded conductor to loosen, even leaks the risk of pressure in the presence of crimping；
2, the copper pipe crimped cannot be bonded copper stranded conductor completely, and connection place resistance is larger.
3, work step is more, and successively passing through 2~3 people operation could complete.First casing copper stranded conductor is carried out between material preparation
The welding of connection sheet and copper stranded conductor is drawn with the crimping of copper pipe, fuse, and the copper pipe on casing copper stranded conductor is then completed between assembling
Copper stranded conductor in connection sheet is drawn with fuse to crimp.
Utility model content
The purpose of this utility model is in order to make up for the deficiencies of the prior art, to provide a kind of capacitor lead-out wire connection knot
Structure improves the reliability of connection, greatly reduces the contact resistance of junction.
To achieve the above object, the utility model uses following technical proposals：
A kind of capacitor outgoing line connection structure, including fuse draw connection sheet and copper stranded conductor, and the fuse draws connection
The end face of piece is equipped with fixing groove, and the copper stranded conductor is set in fixing groove.
Further, the depth of the fixing groove is 15-25mm.
Further, the aperture of the fixing groove is equal to the diameter of copper stranded conductor.
Further, the copper stranded conductor is set to by welding in fixing groove.
A kind of production method of capacitor outgoing line connection structure, includes the following steps：
Step 1: drawing connection sheet one end punching press fixing groove in fuse using mold；
Fixing groove is of moderate size rationally, needs and electric capacitor casing copper stranded conductor carries out dimensional fits, while there are surplus skies
Between make scolding tin penetrate into fixing groove, ensure connection fixing, which use the direct punching press of mold, it is once-forming, it is simple and convenient,
Consistency is good, avoids leading to mass deviation problem because of human factor.
It is drawn in the fixing groove of connection sheet one end Step 2: capacitor casing copper stranded conductor is put into fuse；
Step 3: tin bar is melted into Xi Shui using electric iron and is slowly penetrated into the gap of copper stranded conductor and fixing groove, instead
It is multiple to operate soldering three times until Xi Shui is fully filled with fixing groove, and covers three layers of tin layers on copper stranded conductor；
Step 4: residual tin is removed with high temperature electric iron.
Further, it is 10-20mm that the copper stranded conductor, which is put into the length in fixing groove,.
Further, the Xi Shui needs into obtuse angle after spreading solidification out.
A kind of capacitor outgoing line connection structure of the utility model, has the following advantages：
1, the influence of the factors such as artificial leakage pressure, virtual pressure is avoided completely.If using cold weld mode, due to by casing copper
Twisted wire is positioned in small circle ring and is crimped with core lead-out wire, and operator's leakage is pressed or dynamics used is too light either with or without occurring,
There is the case where virtual pressure, can not intuitively observe, it need to be by the way of artificially pullling inspection, such as each casing is all in accordance with this side
Formula is checked, than relatively time-consuming, and it is also a kind of damage to connection to pull itself；And use the connection structure of the utility model
Mode, either with or without connection, whether connection is firm finds out at a glance, can avoid artificial influence factor completely, is also easy to the process
Quality examination greatly reduces the Check-Out Time of the process；
2, the reliability of connection is improved.Since connection uses soldering mode, every layer all allows Xi Shui to penetrate into copper stranded conductor and recessed
In slot, three stackings successively add, and can avoid situations such as rosin joint occur substantially, fastness and reliability are also very high.
3, the contact resistance of junction is greatly reduced.The contact resistance that two ways is compared by measurement, using this practicality
The contact resistance of Novel connection type greatly reduces the connection than reducing 70.37% using the contact resistance of cold weld mode
The heating problem at place improves product reliability of operation.
4, the impulsive discharge of high intensity, high current can be born.The connection structure mode that the utility model uses, can bear
High intensity, the heavy current impact discharge test of 1000 times of rated current are multiple, are far above the ability to bear of cold weld mode.
5, simplify operating procedure, liberate operator.Using cold weld connection type, operating procedure is trifling, and operation is not also square
Just, using the utility model connection type, operating process is greatly simplified, working efficiency is improved, saves manpower.
