Precision adapter suitable for small-batch test

Technical Field

The utility model relates to a radio frequency coaxial connector technical field, concretely relates to be applicable to accurate adapter is used in test of small batch volume.

Background

The connector is a mechanism element with electrical connection characteristics, has the main functions of electrical connection and signal transmission between devices and assemblies, between assemblies and cabinets and between systems and subsystems, and is one of essential basic elements for forming electrical connection of a circuit system of a whole machine.

With the continuous development of military radio frequency connector products, the use of connectors is increasing day by day, and the use amount is increased sharply. In addition, the screw-type test adapters on the market are generally standard interfaces, and a nut screwing step is required. Therefore, it is necessary to develop a precise adapter suitable for small-lot testing.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the defects of the prior art are overcome, the precision adapter suitable for small-batch testing is provided, and the problems of long testing period and low testing efficiency of the existing product are solved.

The utility model provides a technical scheme that its technical problem adopted is:

a precise adapter suitable for small-batch test is provided, which comprises

An outer conductor;

and one end of the contact head is provided with an external thread connecting section which is in threaded connection with the outer conductor, and the other end of the contact head is provided with an inserting part which is suitable for being inserted into the threaded connecting hole of the outer conductor of the tested piece and is in conductive contact with the shell of the tested piece.

Further, the insertion part comprises

The end hole groove is formed in the end part of the contact head so that the inserting part forms an annular structure;

a plurality of splitting grooves are formed in the periphery of the inserting part, and each splitting groove is communicated with the end hole groove, so that the inserting part is suitable for radial elastic deformation.

Further, the outer part of the insertion part forms a guiding conical surface.

Furthermore, an inward convex snap ring is arranged in the end hole groove and is suitable for being clamped with the outer wall of the insulator in the tested piece.

Further, the contact is made of beryllium copper.

The utility model has the advantages that:

the utility model discloses an accurate adapter, it relies on contact plug grafting portion structure, removes the process of closing soon of nut meshing in the past from, reduces single product test cycle time, promotes product test efficiency.

The form of the inserting part of the contact head replaces screw thread screwing, and a guide device is designed between the outer conductor of the tested piece and the contact head so as to realize blind matching inserting between the contact head and the tested piece, reduce testing procedures and increase testing efficiency; meanwhile, because the measured voltage standing wave ratio and the insertion loss of the adapter are small, the influence on the electrical performance of the measured piece can be ignored.

Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

As shown in FIG. 1 and FIG. 2, a precision adapter for small lot testing includes

An outer conductor 1;

and one end of the contact head 2 is provided with an external thread connecting section which is in threaded connection with the outer conductor 1, the other end of the contact head is provided with an inserting part 21, and the inserting part 21 is suitable for being inserted into a threaded connecting hole of the outer conductor of the tested piece 6 and is in conductive contact with the shell of the tested piece 6.

In this embodiment, a left insulator 31 is disposed in the contact 2, a right insulator 32 is disposed in the outer conductor 1, an inner conductor 4 is disposed between the two insulators, two ends of the inner conductor 4 are respectively inserted into the insulators on two sides, and the other end of the outer conductor 1 is connected to a nut 5 through a snap ring.

Specifically, as an alternative embodiment in this embodiment, as shown in fig. 1 and fig. 2, the insertion part 21 includes

An end hole groove 22 opened at the end of the contact 2 so that the insertion part 21 forms a ring structure;

a plurality of split grooves 23 are formed in the periphery of the insertion part 21, and each split groove 23 is communicated with the end hole groove 22, so that the insertion part 21 is suitable for radial elastic deformation.

Specifically, as an alternative embodiment in this embodiment, as shown in fig. 1 and fig. 2, the outer portion of the insertion part 21 forms a guiding tapered surface 25.
