Abstract
The utility model discloses a coaxial attenuator, belonging to an element applied in the microwave radio frequency field. The coaxial attenuator comprises a heat dissipating sheath, a main body provided with a hollow cavity, an attenuating plate, a signal input connector and a signal output connector. The main body is installed in the heat dissipating sheath and two fixing grooves face to face with each other are arranged on the inner wall of the main body. The attenuating plate is respectively matched with the fixing grooves through two elastic plates to be suspended in the hollow cavity of the main body. The signal input connector is matched and connected with the heat dissipating sheath at one end through screw threads, and an inner core in the signal input connector contacts with one end of the attenuating plate through an input thimble. The signal output connector is matched and connected with the heat dissipating sheath at the other end through screw threads, and an inner core in the signal output connector contacts with the other end of the attenuating plate through an output thimble. The structure of the coaxial attenuator is better for heat dissipation and the coaxial attenuator can be arranged to have big power.
Description
Technical field
The utility model relates to the components and parts that are used for deamplification that use in a kind of microwave radio field.
Background technology
Coaxial attenuator is widely used in the microwave radio field, as radiofrequency signal is decayed, in case stop signal distortion etc. and since coaxial attenuator to the requirement of heat radiation than higher, the structure of therefore existing coaxial attenuator is unsuitable for being made into more powerful coaxial attenuator.
The utility model content
The structure that the purpose of this utility model is to solve existing coaxial attenuator is difficult for the shortcoming of heat radiation, and a kind of simple in structure, coaxial attenuator of being easy to dispel the heat is provided.
The technical scheme that the utility model adopted is: a kind of coaxial attenuator comprises a heat radiation cover; Main body with cavity is installed in the described heat radiation cover, and the inwall of described main body is provided with two holddown grooves respect to one another; An attenuator cooperates in the cavity that is suspended at main body respectively by two shell fragments with holddown groove; A signal input connector is enclosed within threaded one end with described heat radiation and is connected, and the inner core in the signal input connector touches by an end of an input thimble and described attenuator; A signal output connector is enclosed within other end threaded engagement with described heat radiation and is connected, and the inner core in the signal output connector touches by the other end of an output thimble and described attenuator.
The beneficial effects of the utility model are: attenuator was suspended in the main body by shell fragment and cooperating of holddown groove, made attenuator be in contactless state fully, therefore was more conducive to dispel the heat by the heat radiation cover.
Description of drawings
Fig. 1 is the blast structural representation of coaxial attenuator described in the utility model.
Embodiment
Now in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
A kind of coaxial attenuator comprises a heat radiation cover 1; Main body 2 with cavity, the inwall of main body 2 are provided with two holddown grooves 21 respect to one another, and described main body is installed in the described heat radiation cover 1; An attenuator 4, attenuator 4 cooperates in the cavity that is suspended at main body 2 with holddown groove 21 respectively by two shell fragments 3; One signal input connector 6, with described heat radiation cover 1 at one end threaded engagement is connected, the inner core in the signal input connector 6 is imported thimble 5 by one and is touched mutually with an end of described attenuator 4, and external signal is transferred on the attenuator 4; One signal output connector 8, be connected in other end threaded engagement with described heat radiation cover 1, inner core in the signal output connector 8 touches with the other end of described attenuator 4 mutually by an output thimble 7, will export by signal output connector 8 through the signal of attenuator 4 decay.
Being the utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
