Clamping sleeve 3 and compression ring are the annular structural part being arranged in inside locknut 1, and in locknut 1 and master
When body 6 is in non-impaction state, compression ring is located at one end of clamping sleeve 3.With reference to Fig. 7, the inner sidewall of clamping sleeve 3 is provided with guiding
The conical surface, and it is maximum to be oriented to internal diameter of the conical surface close to the end face of compression ring；When locknut 1 and main body 6 fixed using helicitic texture,
And make cable fixing head length reduce when, locknut 1 and main body 6 are in impaction state, at this time compression ring in guide cone
It under the action of face, is slid into clamping sleeve 3 from the end of clamping sleeve 3, and the lateral wall of the inner sidewall of clamping sleeve 3 and compression ring pastes
It closes.
In use, locknut 1, main body 6, compression ring and clamping sleeve 3 are equal for cable fixed head provided by the present application
It is set in the periphery of cable, when locknut 1 and main body 6 are along axial compression, compression ring is embedded in the inside of clamping sleeve 3.With
Compression ring enter the increasing of 3 depth of clamping sleeve, the internal diameter for being oriented to the conical surface is gradually reduced, therefore the internal diameter of compression ring reduces, pressure
Tight ring increases the chucking power of cable, to improve the fixed effect of cable.
Optionally, in order to optimize the using effect of cable fixing head, in the present embodiment, compression ring includes being located at clamping sleeve 3
The upper compression ring 2 at both ends and lower compression ring 4, the internal diameter of clamping sleeve 3 are gradually reduced from both ends to middle part.Specifically, clamping sleeve 3
Both ends are provided with compression ring, wherein the upper end of clamping sleeve 3 is arranged in upper compression ring 2, clamping sleeve 3 is arranged in lower compression ring 4
Lower end；Correspondingly, the inner sidewall tool of clamping sleeve 3 is there are two the conical surface is oriented to, the internal diameter of two guiding conical surfaces is from the end of clamping sleeve 3
Tapered towards middle part, the inner sidewall of clamping sleeve 3 is in hourglass shape.When locknut 1 and main body 6 compress, upper compression ring 2 and pushing
Tight ring 4 is embedded along the guiding conical surface to the inside of clamping sleeve 3.
Further, in order to simplify installation process, on the basis of any one above-mentioned embodiment, upper compression ring 2 is set to
The one end of clamping sleeve 3 far from main body 6, the inner sidewall of locknut 1 is equipped with the seal face inside contracted, so as to the end with upper compression ring 2
Face paste is closed.Specifically, the inner sidewall of the upper end of locknut 1 inside contracts to form seal face to the direction close to central axis, seal face
It is bonded with the upper surface of upper compression ring 2.In assembling process, cable fixing head, can be directly sharp without additionally utilizing pressing jig
The end face of upper compression ring 2 is squeezed with seal face, the axial limiting of compression ring 2 in realization.
Optionally, in order to enhance seal face to the limit effect of upper compression ring 2, with reference to Fig. 6, upper compression ring 2 is far from compression
One end of set 3 is equipped with the convex platform of radially evagination, and end face and the seal face of convex platform are fitted and connected.After the completion of compression, on
In the lower end of compression ring 2 in clamping sleeve 3, and convex platform is then erected at the upper end of clamping sleeve 3.
Further, in order to promote the waterproof effect of cable fixing head, on the basis of any one above-mentioned embodiment, under
Compression ring 4 is set to clamping sleeve 3 and is equipped with water proof ring 5 between one end of main body 6, main body 6 and lower compression ring 4, water proof ring 5 it is outer
Side wall is tapered surface, and the internal diameter of the end of main body 6 is along the direction flaring for leaning on proximal end face by center, to be bonded with tapered surface.
Specifically, water proof ring 5 is made of rubber elastomeric material, and the lateral wall of water proof ring 5 is tapered with reference to Fig. 8, and
The outer diameter of water proof ring 5 is gradually increased from the bottom to top；Correspondingly, loudspeaker of the inner sidewall of the upper end of main body 6 in flaring from the bottom to top
Shape.When main body 6 and locknut 1 compress, water proof ring 5 is extruded and is embedded in inside main body 6, the lateral wall of water proof ring 5 and master
The inner sidewall of body 6 is bonded, and water proof ring 5 generates deformation under the extruding of main body 6, itself internal diameter reduces, and is bonded more with cable
Closely, to promote the leakproofness of cable fixing head.
It should be noted that in actual use, water proof ring 5 may be pressed into the inside of main body 6 completely, this is at present
The lower end surface of compression ring 4 can be directly fitted and connected with main body 6, and the two is hard contact, more preferable to the compression effect of compression ring.
Optionally, compression ring 4 enters in clamping sleeve 3 under pushing for convenience when compressing, and lower compression ring 4 is close to water proof ring
5 one end is equipped with the lower convex platform of radially evagination, and the end face of lower convex platform and the end face of water proof ring 5 are fitted and connected.Specifically, pushing
Lower convex platform is arranged in the lower end of tight ring 4, and lower convex platform increases the area of the lower end surface of lower compression ring 4；In compaction process, water proof ring
5 upper end and the end face of lower convex platform directly fit, and lower compression ring 4 is pushed to enter in clamping sleeve 3 upwards.
Further, in order to avoid compression ring rebound or compression ring fall off naturally with clamping sleeve 3, cause compression ring can not
Reach scheduled internal diameter, on the basis of any one above-mentioned embodiment, the hardness of compression ring is less than the hardness of clamping sleeve 3.Example
Such as, upper compression ring 2 and lower compression ring 4 can be used brass material and be made, and clamping sleeve 3 then uses the higher material system of hardness
At.Compression ring hardness is lower to be more prone to produce deformation, that is, is easier to be pressed into clamping sleeve 3；And 3 hardness of clamping sleeve is higher can
Compression ring is preferably squeezed, so that it is unrelaxing to ensure that compression ring clamps cable.
Further, in order to reduce the difficulty in compression ring push-in clamping sleeve 3, with reference to Fig. 6, in any one above-mentioned implementation
On the basis of example, the lateral wall of compression ring is the conical surface.Specifically, for upper compression ring 2, the outer diameter of the conical surface is from top to bottom gradually
Reduce；And for lower compression ring 4, the outer diameter of the conical surface is from top to bottom gradually increased.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
Cable fixed head provided by the utility model is described in detail above.Specific case used herein
The principles of the present invention and embodiment are expounded, the above embodiments are only used to help understand, and this is practical
Novel method and its core concept.It should be pointed out that for those skilled in the art, not departing from this reality
Under the premise of with new principle, several improvements and modifications can be made to this utility model, these improvement and modification are also fallen into
In the protection scope of the utility model claims.
