Description

Coaxial connector with terminate load

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.

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.

Tubular body 11 has first terminal 12 and second end 13, and this first terminal 12 and second end 13 is to being embedded in inward flange 14,15.The inside of tubular body 11 is provided with one a section long alcove 16 of scalariform and a short alcove 17.Tubular body 11 make have first tube 18, second tube 19, an and hexagonal body 111.The outer wall surface of first tube 18 and second tube 19 has screw thread 112,113 and can link with the end fitting of coaxial cable connector.

Insulation assembly combination 20 includes one section cylindric first insulation assembly 21 in rank and is arranged in the long alcove 16, and a tubulose second insulation assembly 22 is arranged at short alcove 17.This first insulation assembly 21 and the second exhausted assembly 22 define a hole 23,24 respectively can be in order to admit latch combination 40.

Circuit board 30 is arranged on the inside terminals of the short alcove 17 of tubular body 11, and adjacent with second insulation assembly 22.Circuit board 30 has a through hole 31, and the diameter dimension of this through hole 31 can be admitted latch combination 40.The inside and outside edge of circuit board 30 is provided with an inside and outside conductive layer 32,33, is provided with one 75 Ω resistance 34 in 32,33 of inside and outside conductive layers.
