Abstract

The utility model relates to an adapter capable of floating. The length of the adapter can be adjusted, and the installation of two changing panels with the same space can be realized. The adapter comprises an adapter body, wherein the left end of the adapter body is an SMA negative head which is connected with the panels by a flange; the right end of the adapter body is a BMA positive head which is connected with the panels by a nut and an elastic washer; a shell I is in interference fit with a shell II; the shell I is provided with an inner conductor I and an inner conductor II, wherein the inner conductor I is inserted in the inner conductor II; one side of the shell II is provided with a shell III; one side of the shell III is provided with a contact; and a spring is arranged between the shell I and the shell III.

Description

Adapter can float

One, technical field:

The utility model relates to a kind of adapter, especially relates to a kind of adapter that floats.

Two, background technology:

In the background technology, existing panel is installed RF coaxial adapters and all is rigidly connected, and two end connectors cannot float relatively.If the joint at adapter two ends all is to be installed on the panel, and the distance between the two panels is variable, the excessive adapter that then can damage of panel distance so too smallly then can't be installed.In order to adapt to this demand, but must design a kind of novel floating panel RF coaxial adapters is installed, but relocation mechanism is set in adapter, with the Design of length of adapter for being slightly larger than two panels spacing maximum, compress adapter so when mounted, adapter is closely contacted fully, then locking adapter with panel, mechanism stable is and firm, and anti-seismic performance is better.

Three, utility model content:

The utility model provides a kind of adapter that floats in order to solve the weak point in the above-mentioned background technology, and its length can be regulated, and can realize the installation with the two panels of spacing variation.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of adapter that floats, it is characterized in that: comprise the adapter body, adapter body left end is the cloudy head of SMA, the cloudy head of SMA is connected with panel by flange, adapter body right-hand member is a BMA sun head, BMA sun head is connected with panel with elastic washer by nut, shell one is an interference fit with shell two, shell one is provided with inner wire one and inner wire two, inner wire one inserts inner wire two, shell 21 sides are provided with shell three, and shell 31 sides are provided with contact head, are provided with spring between shell one and the shell three.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

The utility model since in the adapter indoor design floating installation of band spring, make the length of this connector to regulate, thereby realize the installation of the two panels that changes with spacing, to satisfy the specification requirement of certain airborne engineering project.In addition, because of installing with panel at the adapter two ends, the SMA end is to utilize flange and panel to link together.BMA end is to utilize nut and elastic washer and panel to link together after through walls.These two kinds of mounting meanss have well guaranteed the mechanical stability of entire mechanism, have good anti-seismic performance.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing that cooperates between the two body inner wires;

Fig. 3 is the partial enlarged drawing that cooperates between the two external conductors;

Fig. 4 is the partial enlarged drawing of spring assembly;

Fig. 5 is the schematic diagram that adapter and panel are installed.

Among the figure, 1-contact head, 2-inner wire one, 3-inner wire two, 4-shell one, 5-shell two, 6-shell three, 7-spring, 8-panel one, 9-panel two, 10-BMA sun head, the cloudy head of 11-SMA.

Five, embodiment:

As shown in Figure 1, the left end of this adapter is cloudy 11 of SMA, realizes being connected with panel 1 by flange; Shell 1 is an interference fit with shell 25, and butt contact 1 plays pressuring action.The adapter right-hand member is positive 10 of BMA, realizes being connected with panel 29 with elastic washer by nut;

As shown in Figure 2, this adapter has an inner wire 23 that is similar to the inner wire 1 of contact pin and is similar to jack.Inner wire one 2 heads are dome shape, so good smooth transition can be arranged, and make it enter inner wire 23 smoothly, realize motion mutually.Split four grooves after the inner wire 23 head perforates, and close up, guarantee strong effect between inner wire 1 and the inner wire 23 like this, realize reliably contact;

As shown in Figure 3, the shell 36 that this adapter has a contact head 1 and cooperates with it, between can move mutually.Contact head 1 is split four grooves, and the mouth that rises, and guarantees strong effect between contact head 1 and the shell 6 like this, realizes reliably contact;

As shown in Figure 4, this adapter has a spring 7, by the compression of spring 7 and floating of elongation realization entire mechanism;

As shown in Figure 5, the length overall of this adapter is L1, and panel 8 and 9 spacing are L2～L3, and variable quantity is L3-L2.The length overall L1 of adapter is designed to be slightly larger than L3(such as 0.5mm), during installation, earlier the SMA end is fixed on the panel 1 by flange, recompression BMA end, exert pressure by 36 pairs of springs 7 of shell, because of between inner wire 1 and the inner wire 23, between contact head 1 and the shell 36, can move mutually between shell 25 and the shell 36, so by the compression spring, the length overall of adapter will reduce, when length overall is reduced to when identical with panel 29 spacings with panel 1, locking nut smoothly just, the BMA end just can be realized installation with panel 29.
