Abstract
The utility model relates to an electric connector with the function of preventing radial rotation and axial float. The electric connector comprises an inner conductor, wherein a medium is arranged between the inner conductor and an outer conductor; straight knurlings are arranged on the circumference of the inner wall of the outer conductor radially matched with the medium; when the outer conductor and the medium are matched on the circumference, the medium is fully embedded in clearances among the straight knurlings to realize the radial torque requirement; and the straight knurlings have discontinuity, thereby being capable of realizing the axial retentivity requirement of the outer conductor and the medium. The utility mode has the advantages of simple structure, high reliability, convenient processing and high productivity effect.
Description
Technical field
The utility model belongs to the connector technique field, and particularly a kind of have an electric connector that prevents from radially to rotate with the axial endplay function.
Background technology
The application of electric connector is very extensive, reliability requirement to electric connector is also more and more higher thereupon, particularly the mechanical performance except that electrical property also requires higher, using traditional structure far can not satisfy than the axial confining force between connector outer conductor and medium and radially torque demand greatly, at present, prevent that the electric connector that radially rotates with axial endplay from mainly containing following several:
First kind, on the inwall circumference of electric connector outer conductor hangnail is set, increase the frictional force between medium and outer conductor.This structure can only satisfy the axial confining force requirement between outer conductor and medium, can not satisfy the radially torque demand of big electric connector, and this structure generally only is applied in the electric connector of small size or medium volume the not exclusively suitable bigger electric connector of volume.
Second kind, electric connector outer conductor and medium interference fit on circumference increases the two frictional force, reaches certain axial confining force and torque demand radially.But this structure is higher to the machining tolerance required precision of outer conductor internal diameter and medium external diameter, is difficult for during batch process guaranteeing; And under high low temperature, medium is prone to medium and leads break-off outward, so there is hidden danger in poor reliability because physical characteristic is expanded with heat and contract with cold, and physical dimension changes.
The third, adopt some riveter skill on the electric connector outer conductor, increase the frictional force between outer conductor and medium, reach certain axial confining force and torque demand radially, but this structure is fit to small size, the thin electric connector of wall, can not satisfy the electric connector of medium volume and larger volume.
The 4th kind, the medium of electric connector is clipped between two outer conductors, increases the frictional force between the three, this infrastructure cost height, complex structure must be finished the processing of two outer conductors, and two outer conductors must be combined closely and just can be finished this structure, and production efficiency is low.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provide a kind of easy to process, production efficiency is higher, simple in structure, and outer conductor in the electric connector is cooperated have more reliably the electric connector that prevents from radially to rotate with the axial endplay function with medium.
To achieve these goals, the technical solution adopted in the utility model is: a kind of have an electric connector that prevents from radially to rotate with the axial endplay function, include inner wire, be provided with medium between inner wire and the outer conductor, it is characterized in that, be provided with straight knurling with the outer conductor inwall circumference of medium radial fit section.
Straight knurling on the said outer conductor is arranged at the part circumferential inner wall, and straight knurling has discontinuity.
Because the utility model is provided with straight knurling with the outer conductor inwall circumference of medium radial fit section, when outer conductor cooperates on circumference with medium, because the rigidity of outer conductor and the plasticity of medium, medium then can fully embed in the gap between the straight knurling, realizes radially torque demand; Because straight knurling is arranged on the part inwall circumference of outer conductor, straight knurling has discontinuity, thus can realize the axial confining force requirement between outer conductor and medium, have simple in structure, reliability height, characteristics easy to process, that production efficiency is high.

Fig. 3 is a radial cross-section of the present utility model; Wherein, Fig. 3 (a) is main cutaway view; Fig. 3 (b) is an A broken section enlarged drawing.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1,3, a kind of have an electric connector that prevents from radially to rotate with the axial endplay function, includes inner wire 4, is provided with medium 1 between inner wire 4 and the outer conductor 2, is provided with straight knurling 3 with the outer conductor 2 inwall circumference of medium 1 radial fit section.When cooperating on outer conductor 2 and the inwall circumference of medium 1 at outer conductor 2, because the rigidity of outer conductor 2 and the plasticity of medium 1, medium 1 then can fully embed in the gap of straight knurling 3 on radial circumference, realizes radially torque demand.
Referring to Fig. 2, straight knurling 3 is arranged on the part circumferential inner wall of outer conductor 2, increases the frictional force between outer conductor 2 and the medium 1, and straight knurling 3 has discontinuity, so can realize the axial confining force requirement of 1 in outer conductor 2 and medium.
Operation principle of the present utility model is:
When outer conductor 2 cooperates on its circumference with medium 1, because the rigidity of outer conductor 2 and the plasticity of medium 1 in 1 gap that can fully embed between the straight knurling 3 of medium, realize radially torque demand; Because straight knurling 3 is arranged on the part inwall circumference of outer conductor 2, straight knurling 3 has discontinuity, so can realize the axial confining force requirement between outer conductor 2 and the medium 1.
