Description

Wire and cable connector

[technical field]

The utility model is about a kind of wire and cable connector, but refers to a kind of wire and cable connector of axial compression especially.

[background technology]

The United States Patent (USP) of announcing on October 4th, 1994 has disclosed the threaded wire and cable connector of a kind of employing for the 5th, 352, No. 134 provides coaxial cable to compress more uniformly.Need rotational motion during owing to be threaded, so this connected mode need consume the more time and assemble, and the spanner that threaded connector often needs the installer to carry different size is deacclimatized the wire and cable connector of different model, will cause installation process complicated like this.

June in 2002, disclosed China's Mainland on the 19th patent disclosed a kind of wire and cable connector that matches with the protuberance of sleeve by the groove of sleeve pipe for No. 01135494.1.This wire and cable connector comprises sealing nut, sleeve pipe, cylinder, lasso, annulus, sleeve and sealing ring.One of them annulus is located between sealing nut and the sleeve pipe and is used to provide environmental sealing, and another annulus is inserted in the groove of sleeve slidably.When sealing ring is used to provide environmental sealing during towards the pushing of the overcoat proximal end of coaxial cable.During this connector axial compression, sleeve proximal end can slide in conjunction with several dactylozoite lassos that separates, the common fixing braid of this lasso and cylinder conductor.Cylinder, lasso and sleeve pipe are housed in the sleeve pipe of connector, when axial compression, form environmental sealing between sleeve pipe and the sleeve, enter to prevent moisture.Can be slidingly connected though this connector can obtain preferable environmental sealing characteristic and sleeve and sleeve pipe, this wire and cable connector complex structure not only can increase manufacturing cost but also reduce production efficiency.

[utility model content]

The purpose of this utility model is to provide a kind of wire and cable connector simple, easy to assembly and that sealing effectiveness is good of making.

The purpose of this utility model is achieved through the following technical solutions: the utility model wire and cable connector is used for and a coaxial line cable fixing, and this wire and cable connector comprises nut, be the hollow form sleeve, be clamped in sealing ring between nut and the sleeve, sleeve pipe, the insertion section that engages mutually with sleeve and the support division that is coated on the outside, insertion section.Wherein coaxial cable comprises inner conductor, inner insulating layer, braid conductor and external insulation layer.Inner conductor and inner insulating layer are retained in the sleeve pipe, and braid conductor and external insulation layer are clamped between sleeve and the sleeve pipe.The insertion section outside is provided with outer rank ring, rank ring in the sleeve inboard is provided with, when the insertion section being pressed into sleeve inner by external force, outer rank ring can with interior rank ring quick-snap, and the degree of depth that the insertion section is pressed into sleeve can be done suitably adjustment according to actual needs.

Compared with prior art, the utility model wire and cable connector advantage is: this wire and cable connector is when axial compression, and the rank ring can encircle quick-snap with rank outside the insertion section in the sleeve, and sleeve, insertion section and coaxial cable cooperate the realization environmental sealing jointly.Not only can adjust the retain strength that the insertion section is pressed into the degree of depth of sleeve but also can increases coaxial cable and insertion section by such design, this wire and cable connector is simple in structure in addition, can reduce cost of manufacture, enhance productivity.

[embodiment]

See also Fig. 1 to shown in Figure 3, the utility model wire and cable connector 1 is used for being connected with a coaxial line cable 8, and this wire and cable connector 1 comprises nut 2, be hollow form sleeve 5, be clamped in sealing ring 4 between nut 2 and the sleeve 5, sleeve pipe 3, the insertion section 6 and the support divisions 7 that engage mutually with sleeve 5.Nut 2 inboards are provided with that screw thread 20 is used for and connecting bolt (not shown) are cooperated, and nut 2 two ends are provided with first opening 21 and second opening 22 in addition.Sleeve 5 one ends are provided with first holding section 50 and the relative other end is provided with ring shaped slot 52, rank ring 51 in 50 inboards, first holding section are provided with.Sealing ring 4 is housed in the ring shaped slot 52 of sleeve 5 and is used to provide environmental sealing.

Sleeve pipe 3 is an elongate body, comprises flange 30 and docking section 31.Docking section 31 is provided with bulge loop 32.Sleeve pipe 3 inserts from first opening 20 of nut 2.Flange 30 is held in second opening, 22 places of nut 2, and extend in sleeve 5 docking section 31, but does not stretch out sleeve 5.Insertion section 6 comprises that second holding section 60 and interface 62, the second holding sections 60 comprise and supports end 60a that rank ring 61 60 outsides, second holding section also are provided with outside, and outer rank in addition encircles 61 length and encircles 51 length greater than interior rank.Support division 7 is provided with the 3rd opening 71 and supporting surface 70.

See also shown in Figure 4ly, coaxial cable 8 comprises inner conductor 83, inner insulating layer 82, braid conductor 81 and external insulation layer 80.Elongated inner conductor 83 is used for conducting electrical signals and normally being formed by conducting metal.Around inner conductor 83 are inner insulating layers 82, and inner insulating layer 82 makes inner conductor 83 insulation, and makes loss of signal reduce to minimum degree.Braid conductor 81 stretches out the formation tubular structure usually, and this structure has the stiff wall with smooth outer surface.External insulation layer 80 is used for nearly step sealing coaxial cable 8 around braid conductor 81.Inner conductor 83 is to be housed in the terminal 9, electrically connects by terminal 9 and butt connector (not shown).

Coaxial cable 8 inserts from the 3rd opening 71 of support division 7.Inner conductor 83 and inner insulating layer 82 are housed in the docking section 31 of sleeve pipe 3, and braid conductor 81 and external insulation layer 80 are clamped between sleeve pipe 3 and the sleeve 5.The supporting surface 70 of support division 7 matches with the interface 62 of insertion section 6, by external force insertion section 6 is pressed into sleeve 5 inside, and this moment, the interior rank ring 51 of sleeve 5 engaged with the outer rank ring 61 of insertion section 6.When the inclined-plane (not label) that supports end 60a and sleeve 5 inboards of insertion section 6 when not contacting, support between the external insulation layer 80 of holding 60a and coaxial cable 8 and acutangulate.When supporting of insertion section 6 holds 60a to contact with the inclined-plane of sleeve 5 inboards, the length that is pressed into sleeve 5 along with insertion section 6 increases, the also corresponding increase of retain strength between coaxial cable 8 and the insertion section 6, when the length that is pressed into sleeve 5 when insertion section 6 reaches maximum, between the two so that the power of holding also reaches is maximum.
