Description
Technical field
The present invention relates to a kind of grafting cable and probe.More particularly it relates to an can plug flexibly
Grafting cable and probe and the manufacture method of grafting cable, the manufacture method of probe.
Background technology
Probe is a kind of device gathering signal for instrument (such as oscillograph), and collection signal is input to by it
In instrument, instrument.Under normal circumstances, it is designed to removable structure between probe and instrument, in order to
Instrument, the carrying of instrument, arrange and use.
Modal probe includes traditional B NC male 1, BNC female 2 and cable 11, as it is shown in figure 1,
Traditional B NC male 1 one end connects existing cable 11, and the other end is connected with BNC female 2.Such as Fig. 2
Shown in, traditional B NC male 1 has a rotatable lock ring 4, its face of cylinder has two symmetrical
Locked groove 3.As it is shown on figure 3, BNC female 2 is welded on the circuit board of instrument and meter, BNC female 2
The face of cylinder on have two symmetrical projections 5, protruding 5 are symmetrically dispersed on the face of cylinder, play lock
The effect of button.
As it is shown in figure 1, use the probe of said structure, need first traditional B NC male 1 to be inserted into BNC
Female 2, then traditional B NC male 1 is rotated to an angle, make the projection 5 in BNC female fall into biography
In locked groove 3 in system BNC male 1, could by traditional B NC male 1 with BNC female 2 closely
Link together.When dismounting probe, it is also desirable to after first traditional B NC male 1 being rotated to an angle,
Traditional B NC male 1 could be extracted from BNC female 2.This structure makes operating process complicated.
As shown in Figure 4, the existing cable 11 being connected with traditional B NC male by crust 6, screen layer 9,
Insulating barrier 7, core 8 are constituted, and core 8 is the medium for transmitting signal.As it is shown in figure 5, traditional B NC
Male 1 is internal is cavity, and has the male through hole 101 that existing cable 11 can be made to insert in one end of cavity
Thus realize existing cable 11 and the connection of traditional B NC male, for coordinating above-mentioned male through hole 101, existing
Having cable 11 also to include tradition contact pin 110, one end of this tradition contact pin 110 is for being used for inserting traditional B NC
The needle-like interface 112 of male through hole 101, the other end is traditional welding hole 113 of welding core 8.It is fixing
Existing cable 11 and the connection of traditional B NC male, existing cable 11 also includes hold-down ring 115.Existing cable
Line 11 with the bus connection method of traditional B NC male is: be enclosed within existing cable 11 by hold-down ring 115；Will
The crust 6 of existing cable, screen layer 9 and insulating barrier 7 are successively pushed aside, and cut out one section of insulating barrier 7 thus
Expose one section of core 8；The core 8 exposed is welded in traditional welding hole 113 of tradition contact pin 110, then will
The needle-like interface 112 of tradition contact pin 110 inserts in traditional B NC male through hole 101；By attached for screen layer 9
In the outside of male through hole 101, then by hold-down ring 115 push-tight, allow hold-down ring that screen layer is uniformly pressed on
On the outer wall of male through hole 101；Use crimper that hold-down ring 115 is pressed into hexagon so that it is can be firm
Fixing existing cable 11 and the annexation of traditional B NC male.
Thered is provided by 200710187286.9 " connecting apparatus for probe of a kind of direct-push " by patent of invention number
In sonde configuration, disclose a kind of new BNC male (hereinafter referred to as customization BNC male), with tradition
The difference of BNC male except the 42nd paragragh and document accompanying drawing 5 in the description of this patent documentation,
11, this customization BNC male disclosed by 12 and 13 does not has lock ring, a locked groove, and have groove 29,
36, upper snap close 14, lower snap close 15 (hereinafter upper snap close, lower snap close being referred to as retaining mechanism) peace
Outside platform 40, with the difference of traditional B NC male 1, customization BNC male 10 also includes that male is connected cable
One end be lock pin 107 rather than male through hole 101, see this specification accompanying drawing 6, lock pin 107 is for passing
The medium of defeated signal, and, platform 40 has screw and the arc-shaped concave matched with the cable face of cylinder.
This structure result in existing cable 11 cannot realize original inserting mode with customization BNC male, it is impossible to
The needle-like interface 112 of tradition contact pin 110 and lock pin 107 are fixedly connected and realize effective biography of signal
Defeated.
