Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing：
As shown in Figures 1 to 4, the dress coupling device of a kind of conducting wire and printing part, including printing part 1, connecting wire 2 and crimping
Terminal 3, printing part 1, which is equipped with, is adapted the connecting hole being fixedly connected with 3 outer diameter of crimp type terminal, and connecting wire 2 is fixed on crimping
In the axis hole of terminal 3；
Crimp type terminal 3 is equipped with peep hole 4, convenient for observing the constant depth of connecting wire 2；
Wherein crimp type terminal 3, which runs through, is fixed on printing part 1；
Specifically, crimp type terminal 3 is welded and fixed with printing part 1；
Crimp type terminal 3 is mutability metalwork, and the compacting of connecting wire 2 is fixed in the axis hole of crimp type terminal 3；
A kind of assembling method of conducting wire and printing part, includes the following steps：
Connecting wire 2 is fixed in 3 axis hole of crimp type terminal by step 1)；Keep connecting wire 2 and crimp type terminal 3 conductive；
Crimp type terminal 3 is fixed in the connecting hole of printing part 1 by step 2).
Specifically, by connecting wire 2 by being fixedly welded in 3 axis hole of crimp type terminal, or make 3 generation machine of crimp type terminal
Tool compression and deformation, realize the fixation of connecting wire 2 and crimp type terminal 3；Crimp type terminal 3 is specifically set to generate symmetric deformation pressure
Trace guarantees connective stability；
Crimp type terminal 3 is run through in the connecting hole for being connected to printing part 1, printing 1 both ends of part, which are welded with crimp type terminal 3, to be connected
It connects.
It is attached being fixedly connected for conducting wire 2 and crimp type terminal 3 using hand crimp connecting tool or automatic crimping tool, makes
Crimp type terminal 3 generates mechanical compression and deformation along conducting wire surrounding, and operating method is easy, and test stone is clear, with crimping tool or
Automatic crimping tool carries out mechanical compaction to crimp type terminal 3 and generates connection.This method can make metal in defined limit internal pressure
It contracts and is displaced and connects the line on contact, make multicore cable and contact material symmetric deformation, crimping connection has gold
Belong to flowing of dissolving each other, good mechanical strength and electric continuity can be obtained.Due to conducting wire be it is twisted by the single round wires core of multiply and
At, therefore all there is certain gap between every core wire, do not allow for being greater than its circle when the circle being twisted deforms
When diameter, the twisted rule of round individual cord certainly will be destroyed and fill gap, when gap filling expires and continues deformation, make conducting wire
Every core wire between and generate plastic deformation between crimp barrel inner wall and form certain stiction, between them
Metallic molecule interpenetrates.After conducting wire is compacted, due to the rigidity of circle individual cord, conductor wire end would not scatter, and form loudspeaker
Shape.
The contact pin end of rigid crimp type terminal is soldered in the plated through-hole of printed board later, due to the size of crimp type terminal
It is suitable for ((thickness diameter is not more than 2mm, long to be no more than 15mm)), wherein pin diameter is 0.762 ± 0.013, and length is about
7mm, the size very can flexibly be placed in any region of printing part, and can be achieved between the contact pin and printed board of rigidity good
Welded connecting.
Since crimping is as a result, generate biggish contact area between contact and conducting wire, it has lesser connect
Electric shock resistance and biggish tensile strength.1, the problem of crimping is not required to solder flux, eliminates corrosion；2, crimping eliminates human factor pair
The influence of termination quality, crimp quality guarantee by tool；3, with No. 20 or smaller line gauge conducting wire, crimping point and conducting wire itself have
There is same intensity；4, crimping contact can be visually inspected；5, crimping tool is universal, improves the standardization of termination
Degree；6, it without carrying out special preparation, can be crimped in place of any need；7, conducting wire is dismountable, hereafter may be used also
It crimps again；8, coaxial cable can also crimp；9, surface cleanness is on connection effect without influence；10, crimping reduces installation dimension
Shield expense；11, crimping is achieved electric connector toward miniaturization；12, crimping does not need heat source, is suitable for various seasons
With various environment；13, no pollutant is crimped, working environment is improved；14, conducting wire wiring unification, specification, unnecessary occupancy are big
Area cabling space improves PCB space utilization rate.After first being crimped using conducting wire, then the method being welded to connect makes complete machine bundle conductor
Wiring technique is achieved toward miniaturization, improves reliability of electrical connection.
By crimp type terminal using characteristic it is found that the crimp type terminal of different size can carry out certainly with the conducting wire of different cross-sectional
By being adapted to, combining.By instance graph as it can be seen that passing through the unitized allocation plan in bonding wire region, product beauty journey not only can be improved
Degree, moreover it is possible to improve the operability (Fig. 4) in production process well.Importantly, after being crossed a pit pressure type crimping bonding wire, by
Much it is better than the bonding strength that conducting wire is directly welded in printed board with the bonding strength for crimping needle in the conducting wire using crimping connection,
By test data, such as：It the use of sectional area is 0.1mm2High temperature wire connected into the crimp type terminal of unification root model 22D
Pulling-out force is greater than 26N, tension number greater than 15 times after sub-assembly is welded to printed board；It and is 0.1mm by sectional area2High temperature lead
Pulling-out force is 20N or so after line is welded direct in printed board, tension number is only 4-5 times.It can be seen that after the optimization used
Bundle conductor connection reliability be significantly improved.Wiring aesthetic measure is become optimizing from original dispersion, in disorder state
Afterwards clean and tidy, uniformly.For PCB layout, standard design criteria, optimization design are played, pcb board space is greatly improved and makes
With the purpose of rate.
