Description

A kind of fast slotting adapter of floating

Technical field

The present invention relates to a kind of adapters, specifically disclose a kind of fast slotting adapter of floating.

Background technique

Conventional adapter device and part thread connecting mode to be measured assembly are cumbersome, especially for the multiport for needing repeatedly to load and unload Network system, lay day will account for a large portion of test total time, reduce production efficiency, increase workload.

Summary of the invention

It is an object of the invention to: one kind can float fast slotting to solve the above problem, easy for installation time saving, can be real Existing multiport grafting simultaneously, reduces the lay day, and adapter is inserted in the floating for improving production efficiency fastly.

The technical scheme adopted by the invention is that such:

A kind of floating slotting adapter, including center conductor, insulator fastly, the center conductor is by contact pin, inner conductor, jack Composition, three are threadedly coupled, and the insulator is circumferentially positioned on the center conductor, further include first shell, second shell, Third shell, spring, the first nut, the second nut, third nut, the second shell and third shell are connected by threaded coaxial It connects, it is whole to run through the first shell；The first shell extends exit in the second shell and fin is arranged, and makes described the One shell radially coincide here with second shell；The first shell is internal, surround the second shell and the third shell Body junction is provided with spring, and the spring one end is abutted with fin in the first shell, the other end and the third shell It abuts；External screw thread is arranged in the second shell front end, and spiral is provided with the first nut；Second nut is in step-like, both ends It is provided with internal screw thread, is nested on the third shell, and is threadedly coupled with the third shell；Second nut portions Divide and extends in the first shell；The third nut and the second nut nested encryptions are arranged.

Further, the second shell and third shell can move freely back and forth with respect to first shell length direction.

Further, radial spacing is 0.5-1.5mm between the first shell and second nut.

Further, the spring contacts with the first shell and is additionally provided with gasket.

Further, the spring is initially in compressive state, by the spring and the first nut by the first shell It is fixed between the second shell.

Further, it is reinforced between second nut and the third nut by screw rod, in the screw rod and described the Retainer ring is provided at three shell abuttings.

Further, third nut one end, test block insertion end are in the shape of a trumpet.

In conclusion due to the adoption of the above technical scheme, the beneficial effects of the present invention are:

Power required for adapter is engaged with part to be measured is provided by spring.Using Hooke's law, become by the elasticity of spring Shape generates axial thrust, guarantees that connection is reliable.Furthermore axis, diameter two-way floating may be implemented in the adapter.It is applicable to multiport Test network, primary assembly realize that multiport engages simultaneously.Radial maximum float amount ± 1mm eliminates machining, assembly is made At error.Axial floating amount is adjustable, it is ensured that electrical reference face comes into full contact with.

Specific embodiment

The present invention is described in further detail below in conjunction with the accompanying drawings.

As shown in Figs. 1-2, a kind of floating slotting adapter, including center conductor, insulator 4 fastly, the center conductor is by inserting Needle 1, inner conductor 2, jack composition, three are threadedly coupled, point screw thread adhesive curing at screw thread；The insulator 4 is circumferentially positioned at institute It states on center conductor, the connection of the two Hough；

It further include first shell 5, second shell 6, third shell 7, spring 8, the first nut 9, the second nut 10, third spiral shell Mother 11, the second shell 6 is connected with third shell 7 by threaded coaxial, whole to run through the first shell 5；Described first It is in flange panel shape that shell 5, which extends exit in the second shell 6, is disposed radially inwardly fin, make the first shell 5 with Second shell 6 is radial here to coincide；There is mounting hole to can mount to special tooling on flange panel, realizes the same fashionable dress of multiport Match；

The first shell 5 is internal, the second shell 6 and 7 junction of third shell are provided with spring 8, It floats and the enough power of axially retaining for providing；Described 8 one end of spring is supported with fin in the first shell 5 by gasket 12 It connects, for cooperating 6 axial floating of the first shell 5 and second shell, the other end supports the gasket 12 with the third shell 7 It connects；

External screw thread is arranged in 6 front end of second shell, and spiral is provided with the first nut 9, adjustable by adjusting the first nut 9 Save 8 pretightning force of spring；For second nut 10 in step-like, both ends are provided with internal screw thread, are nested in the third shell 7 On, and be threadedly coupled with the third shell 7；Second nut 10 extends partially into the first shell 5；The third Nut 11 and 10 nested encryptions of the second nut are arranged.

The second shell 6 and third shell 7 can move freely back and forth with respect to 5 length direction of first shell.

Radial spacing is 1mm (as shown in Figure 2) between the first shell 5 and second nut 10, for adapter diameter To floating correcting.

The spring 8 is initially in compressive state, by the spring 8 and the first nut 9 by the first shell 5 and described It is fixed between second shell 6.

It is reinforced between second nut 10 and third nut 11 by screw rod 13, in the screw rod 13 and the third shell It is provided with retainer ring 14 at 7 abuttings, is interference fitted with 7 outer wall of third shell, guarantees when the second nut 10 is engaged with part to be measured without de- It falls.

Described 11 one end of third nut, test block insertion end are in the shape of a trumpet, guarantee that part to be measured smoothly imports；It uses simultaneously POM plastic does raw material and prevents from scratching test block.

The course of work is as follows:

Calibration:

The end adapter NF is attached by p-wire and Network Analyzer, and the end NM is calibration terminal.

Note: calibration phase, screw rod 13 and third nut 11 are temporarily unassembled, and the second nut 10 does not screw in third shell 7 temporarily On, it can be rotated freely on third shell 7.The second nut 10 is screwed on third shell 7 after the completion of calibration, puts on third Nut 11 is simultaneously fastened with screw rod 13.

1, part to be measured and third nut 11 carry out first contacts, and first shell 5 and the first nut 9 still fit closely not at this time Generate floating.

2, as adapter moves right as shown in Figure 3, F force value is gradually increased, and spring 8 is compressed, first shell 5 with First nut 9 is detached from, and diameter axially generates floating simultaneously.Adapter floats from correcting, and test block is imported in the first nut 9.

3, as adapter continues to move to the right as shown in Figure 3, F force value continues to increase, and spring 8 further compresses, until Adapter comes into full contact with part datum level to be measured, and generates flexible deformation, and spring 8 compresses and in elastic limit at this time, from And part to be measured is sufficiently provided and contacts required power with adapter.

4, after testing, product is separated with test block, is restored to original state.To test next time.

In the above-mentioned course of work, spring 8 provides adapter and floats and keep the power come into full contact with test block.Third spiral shell The radial floating three effect simultaneously of female 11 bell-mouth structure of air, test block from adopting guiding structure, adapter can be achieved floating when docking Dynamic correcting, so that (radial direction ± 1mm) eliminates test block and switching caused by machining and rigging error in certain limit Out-of-alignment phenomenon between device.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
