Description

The ground connection electric connector

Technical field:

The utility model relates to a kind of connector, refers to a kind of electric connector with ground connection effect especially.

Background technology:

In the utilization of signal transmission, for the coaxial cable of conducted signal, normally with the distance that connects intersite, signal frequency, required maximum deflection radius and in specific transmission and/or receiving system permissible space decide the standard of selecting for use.Generally speaking, the coaxial cable of use is long more, and frequency is high more, just needs big more external diameter, to prevent too much spillover.Tradition is applied to such as cable TV, the coaxial cable of aspects such as wide-band-message and microwave signal transmission, and its transmission range is in the scope of 50-1000 Foot, when external diameter is 0.25-1.

Coaxial cable connector is many knowledge of being known.Be linked to interface connector on the coaxial cable connector typical case and make coaxial cable and various electronic device becomes one on electric.

Known coaxial cable has some shortcomings with connector.The main effect of connector is the transmission that the good combination between assurance conductive earthing stratum reticulare and connector body is done electric signal.The known technology problem of connector involves body assembly may produce imperfect earth, and causes the disconnected news of signal, and the connector of F series as shown in Figure 1a can be as a representative example of known connector.F type connector comprises a connector body 10, comprises an outer tube 11, one minor axis pipes 12 and is configured in coaxially in the outer tube 11, and an inner sleeve 13 movably is disposed in the minor axis pipe 12, but a swivel nut 14 be disposed at minor axis pipe 12 around.

Shown in Fig. 1 b, the free end of one cable 15 is inserted in the connector body 10, make the center conductor 16 of cable 15 be positioned at inner sleeve 13 with insulator 17, conductive earthing stratum reticulare 18 and crust 19 then are disposed at outer tube 11 and 13 of inner sleeves and connector body 10 combinations.When cable 15 is inserted in connector body 10 fully, can on cable 15, apply enough pulling force, but force inner sleeve 13 to be moved to inner sleeve and the minor axis pipe place that leans from the front end of swivel nuts 14, make inner sleeve 13 and minor axis pipe 12 become effective ground connection and contact, and the inward flange 111 of outer tube 11 is combined closely with the crust 19 of cable 15.

If the pulling force that puts on the cable 15 is inadequate, can make short 12 of inner sleeve 13 and minor axis have a gap S, and causing 12 of inner sleeve 13 and minor axis pipes to produce loose contact, this loose contact will reduce its electrical characteristic, causes the loose contact therebetween must be to overcome.

So, needing a kind of connector at present, it can effectively and guarantee connector body and coaxial cable are combined, and can guarantee for a long time that connector body forms the ground connection contact, to obtain excellent electric characteristics.

The utility model content:

Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of ground connection electric connector is provided, this connector provides a conductive earthing assembly on inner sleeve, make connector can obtain the contact of firm ground connection, and guarantee signal information transfer quality, and excellent electric characteristics.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of ground connection electric connector, in order to machinery and the electric stube cable of going up in electronic device with connecting interface, this cable comprises a center conductor, one insulator is coated on the center conductor, at least one deck conductive earthing stratum reticulare is arranged at around the insulator, and a crust is coated on the conductive earthing stratum reticulare, this connector comprises together in the shaft hollow, outer sleeve, this inner sleeve is admitted center conductor and insulator, this outer sleeve is admitted conductive earthing stratum reticulare and crust, be characterized in: described connector also comprises a conductive earthing assembly, be configured in the inner sleeve surrounding edge, when cable inserts in the connector fully, apply pulling force on this cable, can promote this inner sleeve to intrinsic displacement, force inner sleeve, conductive earthing assembly and coupling assembling are done contacting on electric.

So, this connector is provided with a conductive earthing assembly on inner sleeve, makes connector can obtain the contact of firm ground connection, and guarantees signal information transfer quality, and excellent electric characteristics.

Embodiment:

Please refer to Fig. 2 and Fig. 3, ground connection electric connector 20 comprises an outer sleeve 22, one coupling assemblings 30, one inner sleeves 40, one conductive earthing assemblies 50.

As shown in Figure 4, this outer sleeve 22 has an outer sleeve body 23, and a hole 24 is defined in its inside, the part length of its diameter dimension receivability coupling assembling 30, and the front end in close hole 24 is formed with a tapered portion 25, and the tip of tapered portion 25 is backward.The end of outer sleeve body 23 has an interior annular rim 26 and defines a hole 27, and diameter dimension makes its free end that can admit coaxial cable 60 (shown in Fig. 8 a).

As shown in Figure 5,30 front ends of coupling assembling at connector 20, this coupling assembling 30 can be used to connecting interfaces such as F type, BNC type, RCA type, IEC type, is that example is done explanation with F type coupling assembling in the present embodiment, and coupling assembling 30 comprises a hexagonal body 31, an and annular end 32.The inside of hexagonal body 31 comprises a screwed hole 33 and an annular rim 34, and screwed hole 33 can have the electronic device of connecting interface in order to admittance, make its mechanically with electric on become one.Annular rim 34 defines a hole 35, and this hole 35 can be passed through for conductive earthing assembly 50.

The inside of annular end 32 has a hole 36, the conductive earthing stratum reticulare 63 of diameter dimension receivability coaxial cable 60 and crust 64, and an annular groove 37 is formed on the outer wall of annular end 32; When the annular end 32 of coupling assembling 30 was inserted in the hole 24 of outer sleeve 22, tapered portion 25 was configurable in annular groove 37, and coupling assembling 30 can be rotated freely in outer sleeve 22.

As shown in Figure 6, inner sleeve 40 has a hole 41, and diameter dimension makes its center conductor that can admit coaxial cable 60 61 and insulator 62.Be surrounded with a sawtooth 42 on the wall in hole 41, the tip of this sawtooth 42 can prevent that coaxial cable and connector are loosening forward.Inner sleeve 40 has a flange end 43, an interface portion 44, reaches a tubular lobes end 45.The size of interface portion 44 is inserted in conductive earthing assembly 50 it, and in the coaxial hexagonal body 31 that is configured in coupling assembling 30.In the hole 36 of the annular end that is configured in coupling assembling 30 32 that tubular lobes end 45 is coaxial, tubular lobes end 45 forms concentric rings around relation with annular end 32, and the centre then is that ring-type hollow 46 is as Fig. 3.Tubular lobes end 45 comprises one first slope 47 and one

second slope

48, and 48 on this second slope is at tubular lobes end 45 ends.

As shown in Figure 7, conductive earthing assembly 50 comprises interface portion 44 surrounding edges that a tubular body 51 is disposed at inner sleeve 40 becomes hesive combination.Tubular body 51 more comprises the front end shell fragment 52 of several slabbings and reaches rear end shell fragment 53, and those front and back ends shell fragments and tubular body 51 are integrally formed.Present embodiment shows four front end shell fragments 52 and four rear end shell fragments 53 with on the tube wall that uniformly-spaced is formed at tubular body 51.
