Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
With reference to the accompanying drawings shown in 1 to accompanying drawing 5, a kind of wave filter with PIN protection of welded joints function, including filter main body 1
Be arranged on the PIN joint 2 of filter main body both sides, the periphery of described each PIN joint 2 is provided with preventer 3, this protection
Device 3 includes the first protection body 310 and the second protection body 320, and described first protection body 310 is fixed in filter main body 1, the
Two protection bodies 320 form tube-in-tube structure by telescoping mechanism and the first protection body 310, move along about the outer wall of the first protection body
Dynamic.
Retractor device includes the guide rail 311 being arranged on the first protection body 310 outer wall, is arranged on the second protection body 320 inwall
And the sliding tray 321 mated with guide rail 311, it is arranged in sliding tray 321, for driving the second protection body 320 left along guide rail 311
The sliding shoe 322 moved right；First protection body 310 and the second protection body 320 are cylindrical structure, and guide rail 311 is by some
It is peripheral that linear type guide rail is looped around the first protection body 310 with array way；Same, on the second protection body 320 inwall slip
Groove 321 mates with guide rail 311, is also loop configuration, and this kind of mode is able to ensure that the smooth degree that the second protection body moves left and right.
Second protection body 320 be provided above lid 330, in order to avoid the something lost of lid 330 falls and loses, lid 330
Being connected with the second protection body 320 by hinge 331, lid 330 can carry out 0 °～the folding of 180 ° by hinge 331；It addition,
Operation to lid 330 for convenience, is provided with projection piece 332 in the middle part of lid 330 upper surface.
The outer wall of the second protection body 320 is horizontally disposed stretching, extension part 323, and lid 330 is outwards beaten by hinge 331
After opening 180 °, just it is shelved on stretching, extension part 323, stretches to be additionally provided with on part 323 and mate with the projection piece 332 on lid 330
Groove 324, when lid 330 open 180 ° be shelved on stretching, extension part 323 on time, projection piece 332 is embedded in groove 323, it is ensured that
The stability of lid 330, the process that lid 330 moves left and right along the first protection body 310 outer wall together with the second protection body 320
In, lid 330 will not collide with the miscellaneous part in the second protection body 320 and filter main body 1.In order to the most really
Protecting the lid 330 stability in moving process, the length stretching part 323 is at least 1/2nd of lid 330 length, i.e. protects
Projection piece 332 on card lid 330 can be embedded in the groove 324 stretched on part 323.
In order to avoid signal disturbing, first protection body the 310, second protection body 320, lid 330 and stretching, extension part 324 are
Isolation material, preferred mass is light, the plastics of low cost or rubber.
The specifically used method of the present invention is as follows:
Under wave filter unused state, the second protection body 320 moves to extreme higher position along the outer wall of the first protection body 310,
The upper port of the second protection body 320 is higher than the port of PIN joint 2, and lid 330 is rotated by hinge 331 and is closed, will
PIN joint 2 surrounds completely, gives full play to dust-proof, waterproof, crashproof effect.
When needing to use wave filter, first, lid 330 is at least outwardly opened 90 °, in order to ensure stablizing of lid 330
Property, preferably outwardly open 180 °, in now the projection piece 332 on lid 330 embeds the groove 324 stretched on part 323, lid
330 are stably shelved on stretching, extension part 323；Then, the second protection body 320 is moved down along the outer wall of the first protection body 310,
PIN joint 2 reveals, for being connected with external equipment.Second protection body 320 can be moved down into extreme lower position, it is possible to
To move on to only expose the position of PIN joint 2, it is connected with PIN joint 2 as long as not affecting external equipment.It is simple to operation,
Second protection body 320 will not interfere with any electrical equipment within filter main body 1 and wire in the process of moving left and right,
There is not potential safety hazard, do not interfere with the service life of wave filter；And, first protection body the 310, second protection body 320, lid
330 and stretch part 324 be isolation material, after being connected with external equipment will not to signal produce disturb.
Above-described embodiment is only the preferred embodiments of the present invention, not limiting the scope of the invention, as long as using
The design principle of the present invention, and carry out non-creativeness work on this basis and the change made, all should belong to the present invention's
Within protection domain.
