Description

A kind of adapter thin-walled is press-fitted anti-cracking structure

Technical field

This utility model is related to a kind of adapter thin-walled and is press-fitted anti-cracking structure, belongs to microwave device technical field, should Structure connector is adaptation microwave device industry product integrated form, the development trend of miniaturization is developed.

Background technology

With whole set equipment miniaturization, loss of weight amount, save space, the development trend easily assembled, being press-fitted using interference fit Structure becomes nearly all universal architecture being related to assembling product such as microwave device, radio frequency connector, is not having spatial design Frequently adopt in the case of the assembling modes such as screw thread, soldering, embedding.When traditional press-fit structure designs, its Press fitting with holes Wall thickness, in more than 0.8mm, is the magnitude of interference typically by the Press fitting dimensional tolerance of tape spool and Press fitting dimensional tolerance design with holes 0.01-0.06mm, is press-fitted using hand punch and puts in place.Traditional press-fit structure is only applicable to adopt screw thread, soldering, embedding Etc. structure, but there is the situation that enough size design are press-fitted；Limited by installation dimension or high-density installation occasion, be press-fitted knot It is even more little that Press fitting wall thickness with holes in structure can be solely 0.2-0.6mm, easily bulge when being press-fitted, is press-fitted mechanism and takes off Fall or because thin-walled lead to Press fitting ftracture, easily cause assembling yield rate low, environmental resistance is poor, use during product The problems such as link structure lost efficacy.

Utility model content

Set forth above for solving the problems, such as, the utility model proposes one kind is press-fitted anti-cracking structure, by general using change The mode of logical rear cover structure, decreases and is press-fitted stress, improves and is press-fitted reliability, improves product reliability.

The technical solution of the utility model is such solution：

Shell and bonnet are press-fitted connection using interference, and shell is the flat thin-wall construction of milling or overall thin-wall construction, and bonnet is Side is V-groove or matrix slot structure.

Milling flat thin-wall construction wall thickness 0.1-0.2mm.

Overall thin-wall construction wall thickness 0.2mm.

Shell and bonnet adopt the press-fit structure that the magnitude of interference is 0.01-0.06mm.

The V-groove of the thin-walled size of this utility model shell and bonnet or concave groove release stress, solve thin well Wall pressure timing shell splits problem, and improves and be commonly press-fitted the bonnet easily occurring and come off problem.

Bonnet Design and Machining is side V-groove or matrix slot structure, when being press-fitted, radial direction has certain elastic force, after being press-fitted It is not result in shell milling flat thin-walled position or the shell pressure break of overall thin-walled, meanwhile, because eliminating solid bonnet pressure after being press-fitted The stress joined, it is press-fitted reliability increases.

This utility model solves shell when thin-walled is press-fitted well and splits problem, and improves and be commonly press-fitted easily to go out Existing bonnet comes off problem.It is applied to product miniature size requirement or the less occasion needing shell milling flat of installing space, its Easy and simple to handle, Stability Analysis of Structures is reliable.

Specific embodiment

Below in conjunction with the accompanying drawings content of the present utility model is further described：

As shown in Figure 1 and Figure 2, a kind of adapter thin-walled is press-fitted anti-cracking structure and is mainly made up of shell 1, bonnet 2, wherein, after Lid 2 has two kinds of structures, and one is V-groove structure 3, and two is female groove structures 4.

Described thin-walled its be mainly shell 1 size-constrained in the case of milling flat wall thickness 0.1-0.2mm (as shown in Figure 3) or whole Body wall thickness 0.2mm about (as shown in Figure 4)；The described anti-cracking structure that is press-fitted is mainly shell 1 and bonnet 2 for interference press-fit structure, Bonnet 2 Design and Machining is V-groove 3 or matrix slot structure 4, when being press-fitted, radial direction has certain elastic force can discharge stress.

Its specific embodiment is as follows：Shell 1 Design and Machining is milling flat (single flat or double flat), milling flat wall thickness 0.1- 0.2mm, i.e. the flat thin-wall construction of shell milling 5, or shell 1 Design and Machining is overall wall thickness 0.2mm, i.e. shell entirety thin-walled Structure 6, bonnet 2 Design and Machining is V-groove structure 3, or bonnet 2 Design and Machining is matrix slot structure 4, and bonnet 2 is press-fitted Enter shell 1.

The above, be only the embodiment of this utility model method, not this utility model imposed any restrictions, every Any simple modification above example made according to technical solutions of the utility model, the change of structure replace all still falling within this In the protection domain of utility model technological system.
