specific Embodiment approach 1

[0020] Specific implementation mode one, such as Figure 1-3 As shown, the cloth 2 is sewn by the flanging method through the thread 1 to form a concave long cloth strip, the width of the concave part is equal to the housing installation groove 6, and the short side of the concave long cloth strip is parallel to the surface of the instrument part 5 Winding, and then put it into the installation groove 6 of the instrument case 3; install the instrument sub-housing 4, fix it through the sealing installation groove slider 8 on the back of the instrument sub-housing 4, and then install the sealing cover 7 to complete the gap. filling. The filling of fabric 2 should ensure that the sewn flanging part is placed on the outside of the gap and the thickness is greater than the width of the gap.

[0021] combine Figure 4 with Figure 5 As shown, the method described in this embodiment mode can also be used for filling plane gaps, and can be used superimposedly.

Abstract

The invention relates to a cloth filling anti-stripping method, and belongs to the field of optical systems and electronics precision mechanical structures. In order to solve the problem that an existing sealing method uses a self-adhesive tape for sealing, and is poor in reliability, particularly to applications to aerospace engineering, a conductive adhesive tape has a precipitation phenomenon of a gum after high and low temperature bonding. The cloth filling anti-stripping method comprises the following steps that 1, long strip-shaped cloth is selected, and flanging sewing on two long sidesof the cloth is conducted by using a line to form a concave long cloth strip; and 2, a gap is filled with the long cloth strip formed in the step 1, and during filling, after the gap is filled, a non-concave part of the concave long cloth strip needs to keep outside the gap with the thickness larger than the width of the gap. The cloth used for sewing is made of conductive fabric, cotton cloth and the like. The sealing method does not use adhesives, and relies on a physical structure of the cloth to fill the gap. The gap may be an irregular geometry. If special requirements exist, the cloth may adopt the conductive fabric.

Description

technical field [0001] The invention belongs to the fields of optical systems and electronic precision mechanical structures, and relates to a cloth filling anti-loosening method, in particular for physical anti-loosening and electromagnetic shielding of the wall-penetrating structure of the CCD focal plane electric box heat pipe of an aerospace camera. Background technique [0002] The existing fabric filling and anti-falling method is a sealing method derived from the inevitable gaps that need to be filled due to special reasons during the structural design of the instrument. The previous sealing method is to use self-adhesive tape for sealing, its reliability is poor, especially when used in aerospace engineering, there are very strict requirements on the condensable volatile matter of the adhesive material, the back adhesive of the conductive tape after high and low temperature bonding has Precipitation phenomenon. Contents of the invention [0003] In order to solve ...
