Description

Coaxial cable connector

Technical field

The utility model is mainly concerned with a kind of coaxial cable connector.

Background technology

At present typical coaxial cable connector is to be screwed together in the satellite interface connector and coaxial cable and various electronic device (for example TV, CB and FM broadcast receiver and ham radio system etc.) are become one on electric as F type coaxial cable connector.

Known coaxial cable connector has some shortcomings.The main effect of connector is to guarantee that the good combination between coaxial braiding conductive layer and connector body carries out the transmission of electric signal.The problem of connector known technology is the intrusion of moisture in the connector body, i.e. moist intrusion between connector body and coaxial cable.The connector of F series as shown in Figure 1, F type connector 10 comprises a connector body 11, it comprises a blowout patche 12, one columnar members 13 and is disposed at blowout patche inside coaxially, a nut 14 be disposed at columnar member 13 around.

As shown in Figure 2, connector 10 inserts its free ends in the terminal 15 of connector body 11, makes the insulator of coaxial cable 16 be positioned at columnar member 13 with center conductor and makes up with coaxial cable 16.The braiding conductive layer of coaxial cable and crust then are disposed between columnar member 13 and the blowout patche 12.An available hexagon crimping tool apply a compression stress in the terminal of blowout patche 12 to combine with cable sheath.

The combination of coaxial cable and FJS series connector utilizes the hex crimp instrument to finish, but this hex crimp instrument fails to apply the outer surface of even compression stress in blowout patche 12, makes the hex crimp instrument stay the zone that some do not compress or part is compressed at the crust and 12 of the blowout patches of coaxial cable 16 on the contrary.These zones become may locating of moisture intrusion, illustrate as arrow 17, then between coaxial cable 16 crusts and blowout patche 12 inner surfaces.The moisture of invading may touch the braiding conductive layer, thereby reduces the signal transmission performance of connector.

The utility model content

Main purpose of the present utility model just is: a kind of coaxial cable connector is provided, and it can closely combine connector body and coaxial cable, thereby can prevent the influence of moisture intrusion and the erosion of rainwater, the mechanical connection between the protection part.

In order to achieve the above object, the solution that the utility model proposes is: a kind of coaxial cable connector, and it is one circular wherein using the coaxial cable of object as it, has a center conductor, an insulator, has a braiding conductive layer and a crust at least; Partly center conductor then is exposed to coaxial cable end, and connector includes a connector body with a blowout patche, a columnar member and this blowout patche formation concentric ring around, the centre then is that ring-type is hollow; One is pressed into compression sleeve around the outer wall in this blowout patche end with a preset distance, it also comprises the lip ring of being located between this blowout patche and this compression sleeve, it has an annular rib, and when coaxial cable is inserted in the connector fully, the outer surface of this flank and crust is connected.

Embodiment

As shown in Figure 7, one conventional coaxial cable 50 is made of center conductor 51, insulator 52, braiding conductive layer 53 and crust 54, for coaxial cable is connected with terminating machine with receiver effectively, outside the terminal partly length of center conductor 51 and insulator 52 must be cut and is exposed to, braiding conductive layer 53 is outside strip off one segment length from insulator 52 places, and covers on the crust 54.

As shown in Figure 3 and Figure 4, connector 20 includes an a connector body 21 and a lip ring 40.Connector body 21 has an annular blowout patche 22, one columnar member 23 forms concentric ring around relation with blowout patche 22, the centre then is a ring-type hollow 24, one can be disposed at the preceding auspicious of connector 20 by rotating circular nut 25, the end of nut 25 is one to the flange 26 that is embedded in, this flange 26 is clipped between the outward flange 27 and blowout patche 22 of columnar member 23, and can rotate freely at

columnar member

23 and 22 of blowout patches, and an annular compression sleeve 30 is pressed into terminal region 28 in blowout patche 22 with a preset distance.

As shown in Figure 5, sleeve 30 has a tubulated ends 31 and an inward flange end 32.Auspicious 31 of tubulose defines a boring 33, and the size of its diameter makes its receivability blowout patche 22.Boring 33 ends at a slope 34 in inside.Inward flange end 32 defines a boring 35, and the size of its diameter makes the free end of its receivability coaxial cable.

As shown in Figure 6, seal 40 is formed as Ni Aopulin (neoprene) by synthetic plastic or synthetic rubber or elastic material, and it has a leading section 41, auspicious 42 and one annular rib that inwardly concaves 43 in a back.Boring 33 surrounding edges that the outer surface of

end

41,42, front and back is disposed at tubulated ends 31 become the combination that power is being arranged, and rearward end 42 is adjacent on the slope 34 of sleeve 30.The end was 41,42 before and after annular rib 43 was positioned at, and became concentric ring around relation with the terminal of columnar member 23, and the centre then is a ring-type hollow 44.

Connector as shown in Figure 7 and Figure 8 is incorporated into the step of coaxial cable.First step is the free end that compression sleeve 30 terminals of connector 20 is inserted in coaxial cable 50, and the center conductor 51 of coaxial cable and insulator 52 are extended in the columnar member 23, and braiding conductive layer 53 and 54 of crusts extend to 22 of columnar member 23 and blowout patches, so, coaxial cable 50 is inserted in the connector fully, and the outer surface of annular rib 43 and crust 54 is connected.Second step applies an insertion force on sleeve 30, so that sleeve 30 is pushed in outside the blowout patche 22 of connector body 21.Can utilize a compression tool to finish when applying insertion force.
