Description
Technical field
The utility model relates to a kind of shielding sheet material testing window structure, belongs to the technical field of electromagnetic shielding material performance test.
Background technology
At present, the method for test electromagnetic shielding material performance mainly contains: full-page proof fenestration, coaxial insertion mensuration and arch mensuration.The necessary condition of full-page proof fenestration is to set up a screened room by designing requirement, and at barrier shield of the centre position of screened room design and installation, four limits of this wall will contact well with the wall of screened room, and are seamless, constitute electric integrated structure.Have the test dedicated window of certain size at the central part of barrier shield.For preventing being reflected and the refraction interference measurement results of electric wave signal, the surface of all walls in screened room is glued and is applied plate absorbing material, and testing window is of a size of 600mm * 600mm.The measuring principle of full-page proof fenestration is a side (in the screened room) that signal source and emitting antenna is placed barrier shield; And receiver and receiving antenna placed the corresponding other side of barrier shield; Emitting antenna and receiving antenna are over against the center range of test window; Each is apart from barrier shield 1m, so claim the 1m mensuration again.Or each is apart from shielding window 0.3m.Shielding material being fixed on the test window, measuring the field intensity ratio of material front and back, is exactly the shielding properties value.And under prior art, test window clamping shielding material is more loaded down with trivial details, inconvenience.
Summary of the invention
The purpose of the utility model provides a kind of shielding sheet material testing window structure that can clamp shielding sheet material fast.
The technical scheme that realizes the utility model purpose is: a kind of shielding sheet material testing window structure; It comprises the plate frame of hollow and the base of hollow, is fixed with some guideposts on the base, and plate frame is sleeved on the guidepost; The periphery of base is fixed with some locking devices; Be provided with a circle microwave absorbing material around the base cavity pocket, the electromagnetic screen reflection horizon also is installed on the base, this electromagnetic screen reflection horizon is between microwave absorbing material and guidepost.
Further, be provided with the rubber strip of hollow between described plate frame and the microwave absorbing material.
Further, described locking device comprises quick locker and the seat that is locked, and the seat that is locked is fixedly connected on the periphery of base, has handle on the locker fast, and an end of locker is hinged on the seat that is locked fast, and the other end is connected with the scalable depression bar.
Further, described electromagnetic screen reflection horizon is the spring conducting strip, and this spring conducting strip is fixed on the base through support.
After having adopted technique scheme, in order to prevent the interference measurement results that is reflected of electric wave signal, be provided with microwave absorbing material and spring conducting strip at the periphery of test window with refraction.The utility model is installed on the screened room; Shielding sheet material pushes between rubber strip and the microwave absorbing material from the side of the utility model, rotates quick locker, the clamping platen frame; Shielding sheet material is pressed on the microwave absorbing material equably, thereby has realized compressing fast the purpose of shielding sheet material.
