Abstract

The utility model provides a coaxial cable connector, comprising a core pipe, a hexagon head, a waterproof ring, a shell and a plug sheath. The utility model is characterized in that the plug sheath made of elastic material is inserted into the shell and interference fits to the shell. The end part inserted into the shell of the plug sheath is a cylinder-cone-table shape convexity, and a cylinder-cone-table shape groove is arranged in the opening of the shell. The convexity of the plug sheath and the groove in the opening of the shell are interference fitted and connected. When the utility model is used, the plug sheath is inserted into the opening of the shell. The plug sheath is made of elastic material. Because the coaxial cable is fixed by the extrusion action of the shell, the utility model has the advantages of simple structure, convenient use and firm combination with the cable.

Description

Coaxial cable connector

Technical field

The utility model belongs to connector used in the CATV field, relates in particular to a kind of coaxial cable connector.

Background technology

In the CATV system, a large amount of coaxial cables that use, because coaxial cable has an outer quilt outward, in braid is arranged, insulating barrier and center conductor, therefore when connecting, need connector to be connected, as shown in Figure 1, present existing connector is by turret head (1), water proof ring (2), core pipe (3) and shell (4) are formed, core pipe (3) passes turret head (1) and water proof ring (2), is pressed into shell (4) and promptly forms connector, when connecting coaxial cable, cable is penetrated in the shell, clamp shell with specific purpose tool then, make it to become, thereby reach the purpose of fixedly connected cable for hexangle type touch coaxial wire tightly.This connector fixed form is not firm, but also needs specific purpose tool, is not suitable for ordinary consumer and uses, and because of there not being specific purpose tool can't connect firmly, has influenced quality of signals when particularly ordinary consumer connects cable TV.

Patent No. ZL 99241096.7, as shown in Figure 2, be described in the patent of novel coaxial shielding cable connector, novel coaxial shielding cable connector comprises turret head (1), water proof ring (2), core pipe (3), shell (4), it is characterized in that also comprising snap ring (5) and stopper (6), the core pipe passes turret head (1), pack into of shell (4) of water proof ring (2), snap ring (5) is put into stopper (6), and be enclosed in the other end of shell (4), snap ring (5) is ring shape, inside and outside tooth and interlaced is arranged, become the obtuse angle between internal tooth and the external tooth, when connecting coaxial cable, coaxial cable is inserted connector from stopper (6), external tooth effect by snap ring (5), coaxial cable can only be along equidirectional the passing of snap ring (5) bending, and snap ring can be backed down and pass by cable, after being inserted into the position, catch the coaxial cable outer surface as snap ring (5) internal tooth such as the barb and be not drawn out, thereby reach the purpose of fixedly connected cable.Though this connected mode is more firm, manufacturer because will produce a snap ring more, thus the increase production cost, and increased the difficulty of assembling.

Summary of the invention

The purpose of this utility model is: in order to address the above problem, and provide a kind of simple in structure, and easy to install not by instrument, and combine firm coaxial cable connector with cable.

The utility model is achieved in that a kind of coaxial cable connector, comprises core pipe, turret head, water proof ring, shell, plug sleeve, and its special character is: the plug sleeve that elastomeric material is made inserts in the shell, with the shell interference fit.

The end that plug sleeve inserts shell is cylinder taper type projection, and a cylinder taper type groove is arranged in the shell aperture, and the interior groove interference fit of the projection of plug sleeve and shell aperture connects.

The utility model coaxial cable connector, because the interior groove interference fit of the projection of plug sleeve and shell aperture connects, compare with inside and outside tooth cooperation connection on a snap ring and the snap ring with plug sleeve in the prior art, during use, only need insert plug sleeve in the shell aperture and get final product, and plug sleeve is made by elastomeric material, because the shell squeezing action is fixed coaxial cable, event is simple in structure, easy to use, and combines firmly with cable.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Among Fig. 3, Fig. 4, Fig. 5: 1, turret head, the 2, water proof ring, the 3rd, core pipe, 4, shell, 7, plug sleeve, 8, cylinder taper type projection, 9, cylinder taper type groove, 10, coaxial cable.

As shown in Figure 3, Figure 4, a kind of coaxial cable connector comprises turret head 1, water proof ring 2, core pipe 3, shell 4 and plug sleeve 7; Plug sleeve 7 is made by the plastic cement elastomeric material, core pipe 3 passes turret head 1, pack into of shell 4 of water proof ring 2, pack into the other end of shell 4 of plug sleeve 7, the front end of plug sleeve 7 has cylinder taper type projection 8, and the external diameter of cylinder taper type projection 8 is greater than the internal diameter of shell 4, and the external diameter of plug sleeve 7 mid portions is also greater than the internal diameter of shell 7, and between shell 4 and core pipe 3 certain clearance is arranged, shell 4 has cylinder taper type groove 9 in the opening of an end of the plug sleeve 7 of packing into.Cylinder taper type projection 8 cooperates connection with cylinder taper type groove 9, and not together with shaft cable 10 time, plug sleeve 7 and shell 4 closely link together and be not drawn out.

As shown in Figure 5, when connecting coaxial cable 10, only need coaxial cable 10 is inserted connector from plug sleeve 7, because the external diameter of plug sleeve 7 is bigger than the internal diameter of shell 4, add that plug sleeve 7 has certain elasticity, under the effect of external force, plug sleeve 7 is pressed in the gap between shell 4 and the core pipe (3), after plug sleeve 7 was shifted the position onto simultaneously with coaxial cable 10, when drawing coaxial cable 10 again, plug sleeve 7 was tightly pushed down coaxial cable 10 and is not drawn out, so promptly finished the assembling of coaxial cable, saved the loaded down with trivial details of other accessory, simple, and the production cost that reduces.

Claims

1, a kind of coaxial cable connector comprises core pipe, turret head, water proof ring, shell, plug sleeve, it is characterized in that: the plug sleeve that elastomeric material is made inserts in the shell, with the shell interference fit.

2, connector as claimed in claim 1 is characterized in that: the end that plug sleeve inserts shell is cylinder taper type projection, and a cylinder taper type groove is arranged in the shell aperture, and the interior groove interference fit of the projection of plug sleeve and shell aperture connects.
