Description
Technical field
The utility model relates to the components and parts that play the signal attenuation effect that use in a kind of microwave radio field.
Background technology
Coaxial attenuator is widely used in the microwave radio field, signal is decayed, avoid occurring phenomenons such as distorted signals, there is not easy-to-assemble problem in the structure of existing coaxial attenuator in manufacturing process, if and a certain assembly damage of coaxial attenuator, also be not easy to maintenance.
The utility model content
The purpose of this utility model is to solve the problems referred to above that existing coaxial attenuator exists, and a kind of coaxial attenuator that is easy to assemble is provided.
The technical scheme that the utility model adopted is: a kind of coaxial attenuator comprises the main body of dispelling the heat and overlapping and being mated installation; Described main body comprises that one is positioned at the outside cover body part of the cover that dispels the heat and a main part that is positioned at heat radiation cover inside; Described main part is provided with first notch district that transmission board is installed and the second notch district that attenuator is installed in turn at each interval from the transmission direction of signal, described main part is initial with the first notch district, and stops with the first notch district; Described transmission board and attenuator are installed in the second and first notch district by screw respectively, described attenuator is a double lead flange resistance, its by self lead-in wire respectively with the both sides transmission board on the conductor conducting, described main part be provided with dispel the heat the cover cooperate the installation external screw thread; One signal input connector is connected the conductor conducting on its inner core and the section start transmission board with the cover body part threaded engagement of described main body; One signal output connector is connected the conductor conducting on its inner core and the termination transmission board with the end thread of the main part of described main body.
The beneficial effects of the utility model are: transmission board and attenuator all are to be installed on the corresponding position by screw, are installed in by screw on the relevant position of main part as the flange arrangement (promptly having screwed hole) of attenuator by self, and be very convenient.
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.As shown in Figure 1, coaxial attenuator comprises heat radiation cover 2 and the main body 3 that is mated installation.Described main body 3 comprises that one is positioned at the outside cover body part 32 of heat radiation cover and a main part 31 that is positioned at heat radiation cover 2 inside.Described main part 31 is provided with first notch district 312 that transmission board 8 is installed and the second notch district 311 that attenuator 7 is installed in turn at each interval from the transmission direction of signal, main part 31 is initial with the first notch district 311, and with 311 terminations of the first notch district, transmission board 8 is installed in the first notch district 312 by screw 5, attenuator 7 is a double lead flange attenuator, it is by the flange of self, utilize screw 6 to be installed in the second notch district 311, its the lead-in wire respectively with both sides transmission board 8 on conductor (as microstrip line) conducting, as by the welding mode connect.Main part 31 is provided with the cover 2 that dispels the heat and cooperates the external screw thread of installing.One signal output connector 1 is connected the conductor conducting on its inner core and the section start transmission board 8 with cover body part 31 threaded engagement of described main body 3; One signal input connector 4, be connected with the end thread of described main part 31, conductor conducting on its inner core and the termination transmission board 8, promptly radiofrequency signal inputs to the inside of coaxial attenuator by signal input connector 4, through after the decay of attenuator 7 by signal output connector 1 output.
Be provided with three transmission boards 8 and two attenuators 7 in the present embodiment, therefore, have a notch district longitudinally on the described main part 31, and be divided into three parts by two horizontal passages, form three first notch districts 312, and the interconnection place promptly forms two second notch districts 311.
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.
