Abstract

The utility model provides a coaxial cable joint which comprise an outer sleeve barrel and a tubular axle seat. The tubular axle seat is sheathed on a cable sheath, the outer sleeve barrel is pressed at the outermost part of the cable sheath by a machine tool, the front end of a cable enters the inner part of the outer sleeve barrel, the inner part of the outer sleeve barrel is a converging conical surface and a plurality of diagonal chamfers, and the back surface of the outer sleeve barrel is provided with a buckling groove which is dented. The front end of the column shaft of the axle seat is provided with a plurality of claws, and front end of the outside of each claw is provided with a concave ring groove, and the inner side of each claw is a tooth shape. When the outer sleeve barrel and the tubular axle seat are pressed with each other, the claw part of the axle seat is converged and deformed at the conical surface of the front end of the inner side of the outer sleeve barrel; so the claw part of the axle seat can be positioned in an interstice of the outer sleeve barrel; thus, the outer sleeve barrel and the axle seat can be tightly matched with each other and can tightly clamp the cable; thereby, the odd parts are not needed, and the easy joint assembly is realized.

Description

A kind of coaxial fitting

The utility model relates to a kind of coaxial fitting.

As shown in Figure 5, existing joint has three assemblies, is respectively outer sleeve 40, axle bed 50 and the tail collar 60, establish the less inner core of a diameter 41 again in outer sleeve 40 tubular inside, and outer sleeve 40 runs through whole body by inner core 41; Axle bed 50 is one the plastic tube of proper wall thickness, length to be arranged, and can directly be enclosed within the outside of coaxial cable 70, and the ora terminalis of axle bed 50 aligns with the axle center root of coaxial cable 70, establishes a bulge loop rib 51 near the tail end of axle bed 50.

When outer sleeve 40 puts

coaxial cable

70,71 of the internal coated layer 72 of inner core 41 insertion coaxial cables 70 and crusts, after internal coated layer 72 stretched into inner core 41, its core stretched out the other end, crust 71 and inboard cover wire then to be stuck in the shell and 41 of the inner cores of outer sleeve 40 fixing outward.

Above-mentioned coaxial fitting has following shortcoming:

1, no special buckle structure between outer sleeve and axle bed will compress the two, need to use facility and could screw in the brute force rotation, because the two does not have special clamping anchor point, the difficult assembling when engaging.

2, inner core is inserted the crust inboard of coaxial cable, easily coaxial cable is damaged.

3, the tail collar at the axle bed tail end is that a becket is a location part, and it increases number of spare parts.

The purpose of this utility model is to provide a kind of coaxial fitting, and itself and coaxial cable are easy to assembly, and fastening force is strong; Its parts are few, save cost and built-up time; Easily manufactured; When assembling, do not damage cable.

The purpose of this utility model is achieved in that a kind of coaxial electrical light fitting, includes an outer sleeve and a plastic tube-shape axle bed; Axle bed is enclosed within on the cable sheath, with facility outer sleeve is pressed in most external and it is assembled in cable end, and outer sleeve forms the narrower conical surface of bringing together in interior forward end, establishes a recessed catching groove at the rear portion apart from the suitable distance of opening; Axle bed has many elongated slots at the front end of shaft, and makes this end form a plurality of pawl structures, and one determining deviation place establishes a concave ring groove at the outside of each pawl front end, and makes the end of each pawl be formed with the fin edge, and the medial surface at each pawl has toothing in addition; The tail end of outer sleeve is enclosed within the front end of axle bed temporarily, and the fin edge snap-on of each pawl of axle bed is in the catching groove of outer sleeve; The open rearward end of outer sleeve inside, catching groove front side and conical surface end have oblique chamfering respectively.

Because outer sleeve meat portion has the conical surface and oblique chamfering to cooperate with the claw-like axle bed, make the axle bed sleeve inner passing of taking advantage of a situation outside, so the power of assembling needn't be too big, assemble more conveniently, and fastening force is strong; Because the application of force needn't be excessive, omitted the tail collar of existing joint tail end, can save cost and built-up time; Because outer sleeve is not the concentric bitubular, makes more convenient; Owing to need not penetrate coaxial cable, can not damage cable.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a STRUCTURE DECOMPOSITION schematic diagram of the present utility model.

Fig. 2 is the structure cutaway view of the utility model outer sleeve.

Fig. 3 has just inserted the enforcement illustration of axle bed for outer sleeve of the present utility model.

Fig. 4 is an assembled sectional view of the present utility model.

Fig. 5 is the assembled sectional view of existing coaxial fitting.

As shown in Figure 1 and Figure 2, the utility model is two assemblies, and one is an outer sleeve 10, and another is an axle bed 20; These outer sleeve 10 inside connect, this pipe interior front end is the narrower conical surface of bringing together 11, and establish a recessed catching groove 12 at the rear portion apart from the suitable distance of opening, and open rearward end, catching groove 12 front sides and the conical surface 11 ends in outer sleeve 10 inside form

oblique chamfering

15,14,13 respectively.

Shown in Fig. 1,3, plastic axle bed 20 is a tubular body, it has the gilled rings 22 of protrusion at tail end, front end at shaft 21 has many elongated slots 23, and form a plurality of pawls 24 at this end, in the outside of each pawl 24, one determining deviation place establishes a concave ring groove 25 apart from front end, and the end that makes each pawl 24 is formed with the less fin edge 26 of internal diameter, and the medial surface at each pawl 24 has tooth 241 in addition.

Shown in Fig. 1,3,4, the utility model is peeled off the crust 30 of coaxial wire link earlier when assembling, and outer wire 31, internal coated layer 32 and the axle core 33 of covering wherein exposed; Again with axle bed 20 be enclosed within the crust 30 of coaxial cable on, and make fin edge 26 inboards of its shaft 21 ends be against the end of crust 30 thereafter; The tail end of outer sleeve 11 is enclosed within temporarily the front end of axle bed 20, because axle bed 20 each pawl 24 are as bullet moon shape, its end is stretched into wherein, and with fin edge 26 snap-ons in the catching groove 12 of outer sleeve 10, with facility outer sleeve 10 covers are pressed in axle bed 20 outer rims, because outer sleeve 10 inner edges have

oblique chamfering

13,14,15, the shaft 21 of axle bed 20 can be taken advantage of a situation to be passed forward, and at 11 places, surface of outer sleeve 10 inboard front ends receipts card, even distortion, when each pawl 24 distortion of axle bed 20, just can insert elongated slot 23 spaces, axle bed 20 is closed with outer sleeve 10 cooperates, and can be easily and firmly will cover this section of wire outward and be fixed on therebetween, exert oneself but needn't be too big.
