Description
Technical field:
The utility model relates to a kind of coaxial connector, particularly a kind of coaxial connector with terminate load function.
Background technology:
In cable television system relevant television systems such as (CATV), must signal be transmitted with coaxial cable; The free end of this coaxial cable links an end fitting, the coaxial fitting of this end fitting and TV through coaxial connector make its become mechanically with electric on binding so that signal be output/import.At this moment, when not being set up as if electronic devices such as TVs, coaxial connector just can not link with coaxial fitting, and becomes idle joint.At this moment, it is dangerous and the situation that signal leaks takes place that the noise arround the coaxial connector that is considered to idle joint may allow enters.This shows that this idle joint has produced that impedance does not match and noise such as enters at problem, and allows the video signal quality be interfered, this mainly is because there is no due to the terminate load assembly with impedance matching in the coaxial connector, and this problem must be remedied.
The utility model content:
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, provide a kind of coaxial connector with terminate load, an end of this coaxial connector is not connected when using, and can have the function of terminate load.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of coaxial connector with terminate load, comprise a tubular body, insulation assembly combination and a circuit board, and this tubular body has one first terminal and one second end; This insulation assembly combination coaxial is arranged in this tubular body, is characterized in: also comprise latch combination; This insulation assembly combination has first end of first insulation assembly near this tubular body, and second insulation assembly is near second end of this tubular body; It is interior and adjacent with second insulation assembly that this circuit board is arranged at this body, and this circuit board is provided with an inside and outside conductive layer, is provided with the resistance with impedance matching between this inside and outside conductive layer; This latch combination coaxial is arranged in this first insulation assembly, second insulation assembly and the circuit board, this latch combination has a steady pin, a removable pin, reaches an outward flange, this steady pin is configured in first insulation assembly, this removable pin is configured in second insulation assembly and the circuit board, can inwardly shrink back or advance along axis direction, this outward flange can contact with inner conducting layer or separate; When contacting with inner conducting layer, outward flange forms an impedance matching.
The beneficial effects of the utility model are that when second tube of tubular body did not use with interface connector, the outward flange of removable pin closely contacted with the inner conducting layer of circuit board and forms one 75 Ω impedance matchings, and has the function of terminate load; And removable pin mobile can affect outward flange inwardly to shrink back and separate with the inner conducting layer of circuit board and contactless simultaneously, makes tubular body become the function of general joint, can solve that impedance that prior art brings does not match and noise such as enters at problem.
Be further to understand feature of the present utility model and technology contents, please consult in detail following about detailed description of the present utility model and accompanying drawing, yet appended graphic only for reference with usefulness is described, and be not to be used for the utility model is done any restriction.

Embodiment:
See also Figure 1 and Figure 2, coaxial connector 10 with terminate load of the present utility model comprises a tubular body 11, one insulation assembly combination 20 is arranged in the tubular body 11, and a circuit board 30 is arranged in the tubular body 11, and latch combination 40 is arranged in the tubular body 11.
As shown in Figure 3, latch combination 40 has a steady pin 41 and is configured in first insulation assembly 21; One removable pin 42 is configured in second insulation assembly 22 and the circuit board 30; And an outward flange 43 is arranged on the removable pin 42.Steady pin 41 has first accommodating chamber 412 and second accommodating chamber, 44, the first accommodating chambers 412 and is provided with a latch 45 and can becomes with the center conductor of end fitting and be electrically connected, and second accommodating chamber 44 is provided with a spring 46.Removable pin 42 has a tubulated ends 47 and a club 49, and this club 49 is arranged on second accommodating chamber 44 of steady pin 41.The internal configurations of tubulated ends 47 has a latch 48.When tubulated ends 47 is subjected to " X " during the strength of direction (as shown in Figure 2), removable pin 42 can inwardly be shunk back, and it is contactless to force the inner conducting layer 32 of outer bead 43 and circuit board 30 to separate, as shown in Figure 4.
See also Fig. 1 and shown in Figure 5, with screw thread 112 be combined intos of an end fitting 50 and first tube 18 of tubular body 11 for mechanically with electric on be connected, and second tube 19 of tubular body 11 does not use with interface connector, at this moment, the outward flange 43 of removable pin 42 closely contacts with the inner conducting layer of circuit board 30 32 and forms one 75 Ω impedance matchings, so when second tube 19 of tubular body 11 did not use with interface connector, tubular body 11 had the function of terminate load.
See also Fig. 1, Figure 6 and Figure 7, when if first tube 18 of tubular body 11 and second tube 19 combine with end fitting 50,51, the inside flat 53 of the fastener 52 of end fitting 51 will promote insulation headgear 411 and move inward, force removable pin 42 inwardly to be shunk back, till inside flat 53 props up inward flange 15, during sealed, removable pin 42 mobile can affect outward flange 43 inwardly to shrink back and separate with the inner conducting layer 32 of circuit board 30 and contactless simultaneously, makes tubular body 11 become the function of general joint.
Generally speaking, the coaxial connector 10 that the utlity model has terminate load has the function of terminate load and general joint simultaneously, can solve like this that impedance that prior art brings does not match and noise such as enters at problem.
