The spiral type packing ring and using method and the purposes that are used for radio frequency (RF) coaxial connectorTechnical field
The present invention relates to the spiral type packing ring, connect spiral type packing ring and using method and the purposes of machine in particular for radio-frequency (RF) coaxial, belong to engineering goods and new purposes technical field thereof.
Background technology
Radio frequency (RF) coaxial connector belongs to electromechanical integrated product, usually be installed on cable or the instrument, element as transmission line electrical connection or separation, it can transmit electromagnetic wave signal and energy effectively, along with developing rapidly of communications industry, the widespread demand of cable TV industry particularly, radio frequency (RF) coaxial connector more and more is subject to the extensive approval in the industry, existing radio frequency (RF) coaxial connector Main Problems is, in use because the contact-making surface of nut and lining is the plane, in the push-and-pull process or during free state, can come in contact bad, it is unstable to cause like this signal of telecommunication to transmit, thereby affects user's use.
Summary of the invention
The object of the invention is to solve the problem that above-mentioned prior art exists, a kind of reasonable in design is provided, contacts well, can guarantee that signal transmits stable the undaform packing ring and using method and the purposes that are used for radio frequency (RF) coaxial connector.
The present invention is achieved by the following technical solutions:
Be used for the spiral type packing ring of radio frequency (RF) coaxial connector, its special character is to comprise packing ring body 3, and packing ring body 3 is spiral-shaped structure;
The cross sectional shape of described packing ring body 3 is circular;
In order to increase the contact area of packing ring body, the cross sectional shape of described packing ring body 3 is square;
The height of described packing ring body 3 is 0.9-1.2mm, and the height after 3 bendings of packing ring body is 1.05-1.35mm;
The height of described packing ring body 3 is 1.1mm, and the height after 3 bendings of packing ring body is 1.25mm;
Described packing ring body 3 adopts to be made through zinc-plated stainless steel;
The using method of described spiral type packing ring for radio frequency (RF) coaxial connector, its special character is may further comprise the steps:
A, prepare the needed nut of radio frequency (RF) coaxial connector, and install sealing ring for waterproof in the right groove of nut;
B, packing ring body 3 is inserted in the lining;
C, the lining of step b is inserted in the nut;
D, install sealing ring for waterproof in the left groove of nut;
E, shell body is enclosed within the lining periphery.
Described spiral type packing ring, the application on radio frequency (RF) coaxial connector.
The present invention is used for the spiral type packing ring of radio frequency (RF) coaxial connector, the spiral type packing ring has been set up on basis at existing radio frequency (RF) coaxial connector, even produce for some reason so loosening between nut and the lining, can not come in contact bad situation yet, because packing ring of the present invention is spiral type, become flexible even if produce, the contact both sides face of packing ring still is connected with lining with nut and is connected, and so just can guarantee the stability that the signal of telecommunication transmits.

Embodiment
Provide the specific embodiment of the present invention below with reference to accompanying drawing, be used for formation of the present invention is described in further detail.
Present embodiment is used for the spiral type packing ring of radio frequency (RF) coaxial connector, comprises packing ring body 3, and packing ring body 3 is spiral-shaped structure; In order to increase the contact area of packing ring body 3, the cross sectional shape of packing ring body 3 is square; The height of packing ring body 3 is 1.1mm, and the height after 3 bendings of packing ring body is 1.25mm; Packing ring body 3 adopts to be made through zinc-plated stainless steel;
Be used for the using method of the spiral type packing ring of radio frequency (RF) coaxial connector, may further comprise the steps:
A, prepare the needed nut of radio frequency (RF) coaxial connector, and install sealing ring for waterproof in the right groove of nut;
B, packing ring body 3 is inserted in the lining;
C, the lining of step b is inserted in the nut;
D, install sealing ring for waterproof in the left groove of nut;
E, shell body is enclosed within the lining periphery.
The spiral type packing ring, the application on radio frequency (RF) coaxial connector.
The application of spiral type packing ring of the present invention on radio frequency (RF) coaxial connector, it is a very large breakthrough, basis at existing radio frequency (RF) coaxial connector has increased spiral type packing ring of the present invention, just can be so that nut and lining be in tight connection status all the time, prevent loose contact, guaranteed the stability that the signal of telecommunication transmits.
The unspecified content of the present invention is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection scope of the present invention should be determined according to the protection range of claim.
