Abstract

The utility model relates to a coaxial cable connector with an improved structure, which comprises a connecting head and a sleeve barrel, wherein the sleeve barrel is composed of a tubular axle and an elastic ring of which the one end is provided with a concave ditch and a hook part, and one end of the connecting head is provided with a stopping and blocking edge; the inner wall surface of the connecting head is provided with screw threads and a flange. Thereby, after the utility model is combined with a coaxial cable, the connecting head is utilized to screw to the end and to be further tightened when combined with other devices, and the hook part of the elastic ring is tightly combined with the connected surface of the stopping and blocking edge of the connecting head to achieve complete seal without the need of additionally installing any isolating members.

Description

Structure improved coaxial cable connector

Technical field

The utility model relates to a kind ofly need not use any insulating element, can reach the structure improved coaxial cable connector of sealing state, is suitable for connecting the line body of tool signal transmission especially, as coaxial cable line or similar structures.

Background technology

Coaxial cable connector is the main flow of using at present, with F type coaxial cable connector is example, be to be screwed together in subsidy interface connector and make coaxial cable and various electronic device on its typical case, for example TV, CB and FM broadcast receiver and ham radio system etc. become one on electric.The main effect of coaxial connector is the good combination between coaxial baffle and connector body, does the transmission of electric signal.

The existing coaxial cable connector, as shown in Figure 3, F coaxial cable connector 10 comprises a connector body 11, wherein comprises a clamp 12, a columnar member 13 coaxial being disposed in the clamp 12, and O shape ring 15, one nut 14 is disposed at around the columnar member 13.And the free end of coaxial cable is inserted the terminal 16 of connector body 11, and make insulator 17 and center conductor 111 be positioned at columnar member 13, marshalling baffle 18 and crust 19 then are disposed between the outside and clamp 12 of columnar member 13, utilize a hexagon press tool to apply a pressure, seal combination for 19 one-tenth with the crust of coaxial cable to force it in clamp 12.

Above-mentioned connector is when making up with coaxial cable, need to use as insulating elements such as O shape ring or packing rings, again, connector shown in Figure 3 is not to use O shape ring can reach sealing, but fail to apply uniform pressure outside clamp when using the hex crimp instrument, stay unpressed zone on the contrary, those zones promptly become the pipeline that moisture immerses.The moisture of invading may touch the marshalling baffle, thereby reduces the signal transmission performance of connector, or can cause corrosion because of entering of aqueous vapor, and makes the signal transmission influenced.Present O shape ring set on the structure again, after packing, because of the space is filled up in distortion, thus can reach the effect of waterproof, but cause cost to promote because of increasing the member event.

In view of this, the design people's phase can provide a kind of insulating element that do not need additionally to use, and can reach the structure improved coaxial cable connector that blocks moisture, airtight effect, and consumption is popular to be used to provide.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, provides a kind of when being used in combination, and need not use extra spacing body such as O shape ring or the pad of cutting off, and can reach the structure improved coaxial cable connector of sealing effect.

For reaching above-mentioned purpose, this use is novel to provide a kind of structure improved coaxial cable connector, and it comprises:

One connector, inner wall surface thereof is provided with screw thread, and an end also is provided with a stop edge; And

One sleeve is unified elastic ring by the pipe sleeve of a tool guide hole and is formed, and this elastic ring one end is provided with a chase and a hook part;

Fasten stop edge by the hook part of sleeve, to finish the assembling of coaxial cable connector in connector; After coaxial cable was incorporated into sleeve, when utilizing connector and miscellaneous equipment female seat to be screwed to the end, further locking connector abutted against in the female seat end face tubular axis face, makes hook part and the mutual packing of stop edge binding face, form one airtightly completely cut off, the connector of antiseep.

Because the designed structure improved coaxial cable connector of the utility model is made up of a connector and a sleeve; Wherein this sleeve is made up of a tubular axis and an elastic ring, and this elastic ring one end is provided with a chase and a hook part, and the first end of this connection is provided with stop edge, and inner wall surface thereof is provided with a screw thread and a flange; Thus, when the utility model with after coaxial cable combines, when this connector combines with miscellaneous equipment, utilize connector to be screwed to further packing at the end, make the stop edge of the hook part of this elastic ring and connector connect face and form and combine closely, can not reach sealing fully and do not need to add again any insulating element.

Other characteristics of the present utility model and specific embodiment can further be understood in the detailed description of following conjunction with figs..

Embodiment

Please join Fig. 1, the utility model mainly is made of a connector 40 and a sleeve 20, wherein this connector 40 is made as-F type connector, its outer rim one end is set as a hexagon 45, the end of this hexagon 45 inwardly is provided with a stop edge 42, and these connector 40 internal faces are provided with a spiral shell mosquito 44 and a circle flange 41, form a groove 43 between this flange 41 and the stop edge 42.

This sleeve 20 mainly is made up of an elastic ring 21 and a tubular axis 24, wherein these tubular axis 24 1 ends are provided with edge clipping 25 and portion of a plurality of class, and this tubular axis 24 is sheathed in the elastic ring 21, these elastic ring 21 front ends are made as a folding part, the outer rim of this folding part end then is provided with a circle chase 23 and a hook part 22, and the chase 23 of these elastic ring 21 front ends and hook part 22 adhere in the portion of class of tubular axis 24.

During combination, the edge clipping 25 of this tubular axis 24 fastens mutually with the flange 41 of connector 40 inwalls, and the hook part 22 of elastic ring 21 front ends places groove 43 and be subjected to stop edge 42 backstops, at this moment, has a space A between hook part 22 and the stop edge 42, and after coaxial cable inserted sleeve 20 (not shown), internal thread 44 by connector 40 is connected with miscellaneous equipment female seat 50, this connector 40 gives a urgent power again when being locked into the end, make tubular axis 24 faces abut against in female seat 50 end faces, make stop edge 42 urgent mutually thus with the face that connects of hook part 22, the space A that order originally was present between the two disappears, as shown in Figure 2, so aqueous vapor, things such as dust can't enter, so can reach the waterproof effect.

As from the foregoing, structure provided by the utility model has following practical advantage:

1,, make its combination the time not need again can to reach effect airtight, waterproof through the installing of insulating element by simplifying the collocation of member.

2, do not need additionally to refill and establish insulating element, thus make the combination of this coaxial cable connector convenient, and escapable cost.

The above only is preferred embodiment of the present utility model, and when can not be in order to limit the enforceable scope of the utility model, all those skilled in the art obviously can do to change and modification, all should be considered as not departing from flesh and blood of the present utility model.

In sum, the utility model really can reach the intended purposes of design, and a kind of structure improved coaxial cable connector that is provided has practical value undoubtedly.
