Abstract

The utility model relates to a floatable radio frequency coaxial adapter. One end of the coaxial adapter is floatable freely and can completely mesh with a butting connector. The floatable radio frequency coaxial adapter comprises an adapter body, the adapter body consists of a first shell, a BMA (blind-mating) positive plug is arranged at the left end of the adapter body, the BMA positive plug is connected with a first panel through a flange, an SMP (symmetrical multiprocessing) negative plug is arranged at the right end of the adapter body and placed into a mounting opening of a second panel, one side of the first shell is provided with a first inner conductor and a second inner conductor, the first inner conductor is inserted into the second inner conductor, and the other side of the first shell is provided with a contactor and a spring.

Description

The RF coaxial adapters of can floating

One, technical field:

The utility model relates to a kind of adapter, especially relates to a kind of RF coaxial adapters of floating.

Two, background technology:

In the background technology, existing RF coaxial adapters all is rigidly connected, and two end connectors cannot float relatively.If be uncertain (certain limit is arranged) to joint (the cloudy head of the SMP) position of inserting with it, then can cause slotting not in place, perhaps can't can't realize functions peculiar to inserting.In order to adapt to this demand, must design a kind of novel RF coaxial adapters of floating, one end is fixed on panel, but other end free floating, to the joint location of inserting when uncertain, can be to be slightly larger than inserting the length when not in place when with it with the adapter Design of length, will give axial compressive force of adapter when inserting like this, plug together fully and mechanism stable firm, anti-seismic performance is better.

Three, utility model content:

The utility model provides a kind of RF coaxial adapters of floating in order to solve the weak point in the above-mentioned background technology, and the one end can free floating, can realize with the engagement fully to connection-peg.

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

A kind of RF coaxial adapters of floating, it is characterized in that: comprise the adapter body, the adapter body comprises shell one, adapter body left end is a BMA sun head, and BMA sun head is connected with panel one by flange, and adapter body right-hand member is the cloudy head of SMP, be shelved in the installation perforate of panel two, shell side one by one is provided with inner wire one and inner wire two, and inner wire one inserts inner wire two, and shell side one by one is provided with contact head and spring.

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 that an end of this connector can free floating, thus realize with and its joint of inserting is meshed fully, to satisfy the specification requirement of certain airborne engineering project.In addition, because of the BMA of adapter end is to be installed together with panel, the SMP end can free floating, so but with the other end free adjustment of its engagement, adaptability is stronger.

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 adapter scheme of installation.

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-SMP, 12-SMP sun head.

Five, embodiment:

As shown in Figure 1, the left end of this adapter is positive 10 of BMA, realizes being connected with panel 1 by flange; Right-hand member is positive 12 of SMP, is shelved in the installation perforate of panel, but free floating.

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 1 that this adapter has a contact head 1 and cooperates with it, between can move mutually.Contact head is split four grooves, and the mouth that rises, and guarantees strong effect between contact head 1 and the shell 1 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, when the cloudy position of SMP apart from adapter farthest the time, to inserting back adapter length setting is L, the adapter physical length is designed to be slightly larger than L(such as L+0.5mm), during installation, earlier the BMA end is fixed on the panel 8 by flange, recompression SMP sun head end, shell 25 can opposite shell 36 move, and exerts pressure by 25 pairs of springs 7 of shell, between inner wire 1 and inner wire 23, between contact head 1 and the shell 1, can move mutually between shell 25 and the shell 36, so by compression spring 7, the position of adapter SMP sun head end just can be regulated, when SMP is adjusted to suitable position, just can with SMP the moon head end fully to slotting.Because the reaction force of spring makes that contact is more reliable, performance is more stable.
