Embodiment
Below in conjunction with the accompanying drawing example plug of electric connector with mixed of the present invention is described in further detail:
As shown in Figure 1, plug of electric connector with mixed of the present invention comprises high-frequency contact 1, low frequency contact 2, shell 3, pedestal 4, low frequency contact 2 is by pedestal 4 location, and be fixed in the shell 3 with casting glue 5 embeddings, high-frequency contact 1 is also fixing by casting glue 5, and high-frequency contact 1 is comprised of unsteady housing 1a, dielectric 1b, inner wire 1c, spring 1d, inner wire 1e, guide vane end stop 1f, dielectric 1g, insulating washer 1h, stationary housing 1i, high frequency cable 1j, heat-shrink tube 1k.Wherein unsteady housing 1a, dielectric 1b, inner wire 1c form floating end, fix by interference fit between the three; Inner wire 1e; guide vane end stop 1f; dielectric 1g; insulating washer 1h; stationary housing 1i; high frequency cable 1j and heat-shrink tube 1k form stiff end; stationary housing 1i and dielectric 1g fix by interference fit; behind the high frequency cable 1j wire stripping; its metal inside welds with inner wire 1e one end after passing insulating washer 1h; it is stuck to push in the dielectric 1g endoporus interference fit again; the shield sheath of high frequency cable 1j is then fixed with the soldering of stationary housing 1i tail end; the welding position is protected with heat-shrink tube 1k; be provided with guide vane end stop 1f in the described stationary housing, the guide vane end stop that is fixed with pressure in stationary housing cooperates realization with unsteady housing.Described guide vane end stop 1f one side pressure is joined and is fixed in the stationary housing, and top, the other end outside is processed with barb, realizes spacing with the barb combination of described unsteady housing bottom.
The present invention is divided into two parts with inner wire, mode with interference fit is fixed in stationary housing and the unsteady housing respectively, adopt the mode that plugs together of rigid needle and springhole between two inner wires, plug together the degree of depth and surpass the unsteady length that the housing that floats allows, when floating floating shell, corresponding dielectric and inner wire also and then float, and the Elastic Contact of inner conductor pin hole guarantees that contact is reliable.
Realize axial float by spring 1d between floating end and the stiff end, float and realize conducting by Elastic Contact between housing 1a and the stationary housing 1i, also realize conducting by Elastic Contact between inner wire 1c and the inner wire 1e.
When hybrid-assembling electric connector plug of the present invention docked with respective socket, the normal pressure that the housing 1a that floats is subject to docking generation moved down, and simultaneously with spring 1d compression, spring 1d produces reaction force upwards and high-frequency contact 1 docked with its butt end put in place; Continue down docking, the housing 1a that floats also continues down to float, at this moment, because the compressed reaction force that has of spring 1d guarantees all the time that high-frequency contact 1 and its butt end plug together and puts in place; Unsteady housing 1a and guide vane end stop 1f cooperation place are designed with barb, both are press-fitted to put in place first, and barb plays spacing effect, and the housing 1a that prevents from floating comes off from stationary housing 1i.When described hybrid-assembling electric connector plug separates, the downward normal pressure of housing 1a of floating is removed, the tension force of spring 1d so that the housing 1a that floats move upward, and finally limit with the guide vane end stop 1f that press fit among the stationary housing 1i by barb, the housing 1a that guarantees to float is unlikely to deviate from, the amount of floating that guide vane end stop 1f can provide is less than effective contact length of inner wire 1c and inner wire 1e, and this guarantees that also inner wire 1c effectively contacts all the time with inner wire 1e in the location free procedure.
