Description
Technical field
The invention belongs to the technical field of transmission of electric signals, specifically, relate to a kind of network filter.
Background technology
Traditional network filter PIN needle and coil lead connected mode adopt kinking formula, PIN needle are provided with concavo-convex bayonet socket and draw-in groove, and coil lead kinking, on PIN needle tongue and groove, makes lead-in wire be connected conducting with PIN needle by being welded and fixed.But adopt this kind of operating type, complex process is loaded down with trivial details, operation easier is large, in the process of kinking, need to control well the kinking elasticity of coil lead, the tweezers that kinking uses need to polish smooth, make not destroy enamelled wire coat of paint in kinking process, otherwise high pressure can be caused bad, the too sharp meeting of tweezers causes coil lead to rupture.Tradition kinking technique makes PIN solder joint become large, and the consumption of tin material increases simultaneously, more easily causes product short circuit to connect weldering if the spacing between two PIN is narrow; The cost of labor of tradition kinking technique is high, need a large amount of work manpowers, and product fraction defective is high, easily occurs that electric property is not good, cost of idleness.
Summary of the invention
For deficiency above-mentioned in prior art, the invention provides a kind of network filter, solve the PIN needle of current network filter and coil lead adopt kinking connected mode easily to occur breaking, connect weld, the problem such as high pressure and processing cost height.
In order to achieve the above object, the solution that the present invention adopts is: a kind of network filter, comprise housing, PIN needle and inductance coil, housing is provided with groove, inductance coil is arranged in groove, the housing of groove both sides is provided with the cable clamping interface of communication groove, the coil lead of inductance coil is arranged in cable clamping interface; Cable clamping interface edge is provided with installation through hole, and PIN needle is fixedly connected on installs in through hole, and PIN needle runs through housing.The spacing of PIN needle edge and cable clamping interface inwall is less than the diameter of coil lead, and coil lead end is pressed fixing by PIN needle and cable clamping interface inwall, and PIN needle is connected with coil lead soldering.
Further, PIN needle quantity is identical with coil lead quantity.
Further, install through hole upper end and be provided with the flare openings being convenient to install PIN needle, flare openings is coaxial with installation through hole.
Further, the width of cable clamping interface is greater than the diameter of coil lead.
Further, cable clamping interface comprised line skewed slot and card line level trough, crossed line skewed slot and was communicated with groove, card line level trough with line skewed slot be communicated with, card line level trough and mistake line skewed slot wide.
Further, coil lead presses and is connected between PIN needle and card line level trough inwall.
Further, shell rim place is provided with the secant step cutting unnecessary coil lead.
Further, secant step flushes with card line level trough.
Further, secant step is vertical with card line level trough.
The invention has the beneficial effects as follows, in cable clamping interface, be provided with line skewed slot, shorten the length of card line level trough, when wicking is welded, save solder; Secant step flushes with card line level trough and vertical, is beneficial to the coil lead that disposable cutting is unnecessary; Adopt PIN needle and cable clamping interface horizontal interior walls that fixing connected mode is pressed in coil lead end, replace traditional coiling connected mode, technique becomes simple, save manpower and processing cost, avoid the original problem using tweezers easily to destroy coil lead coat of paint, pinch off coil lead, and improve electric property and conforming product rate.
