Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some changes and improvements can also be made.These all belong to protection scope of the present invention.
The present invention relates to the ground switching test of spacecraft, disclose a kind of ground switching test system schema.Comprise: private section transit cable 1, general section of transit cable 2, switching test box 3.The invention solves that spacecraft ground switching test system weight is excessive, cost is higher, carry the problem such as inconvenience, difficult management.The present invention significantly can alleviate the overall weight of the spacecraft ground switching test systems such as satellite, reduces development cost, improves Mobile portable.Application of the present invention can obtain obviously alleviate spacecraft ground test adapting system weight, reduce development cost, improve the beneficial effects such as Mobile portable.
Fig. 1 is the composition schematic diagram of light earth surface switching test System Preferred embodiments of the present invention.Wherein electric connector kind quantity to be measured is 100, and namely the quantity of private section transit cable 1 is 100 bundles, and cable number is ZW001 ~ ZW100, and private section transit cable 1 length is 150mm.The length of general section of transit cable 2 is 2000mm, can simultaneously to the requirement that 4 kinds of difference electric connectors to be measured are tested for meeting ground switching test system, then the quantity of general section of transit cable 2 is 4.
If the average weight of electric connector is pressed 0.04kg and calculated, the average weight of bundle conductor every meter is pressed 0.25kg and is calculated, then in this preferred embodiment, the weight sum of private section transit cable and general section of transit cable is 14.07kg.If designed according to the scheme before the present invention's application, then need 100 bundle transit cables, built-up circuit length is 2000mm, then the general assembly (TW) of transit cable is 58kg.As can be seen here, the cable section designed according to this invention in light earth surface switching test system is than traditional design weight saving 76%, and cost reduces by more than 50%.
From the above mentioned, the present invention carries out step-by-step design by function on traditional transit cable basis, the transit cable in current traditional design is replaced with private section transit cable and general section of transit cable, significantly reduce the weight of spacecraft ground test adapting system, reduce development cost, improve portability.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make a variety of changes within the scope of the claims or revise, and this does not affect flesh and blood of the present invention.
