Description

The rack that communication equipment is used

The utility model relates to communication equipment field, relates in particular to the shielding rack that a kind of communication apparatus is used.

The version of existing communication equipment enclosure is based on sheet metal component substantially, waits and constitutes by welding assembly, screw binding.The interface that this kind rack structure links between parts mutually adopts welding manner to connect usually, because positioning accuracy is hanged down and reached the influence that there is internal stress in postwelding during welding, make the critical component of rack be difficult to guarantee as the dimensional accuracy and the form and position tolerance of enclosing frame, column etc.; Particularly, for will realizing pinpoint location structure, owing to, be difficult to guarantee the size and the form and position tolerance of location structure through the multiple welding assembling.And generally need manual grinding after the welding, be difficult to realize for meticulous surface structure moulding, and be unfavorable for mass production.Shortcomings such as there is low precision in existing rack, manufacturing process is various, the electromagnetic shielding grade is low, appearance difference and production cost height.

The purpose of this utility model is: the rack that provides a kind of communication equipment to use, the basic framework of this rack (as enclosing frame and column) all adopts mold integral die casting to form, and it has, and precision height, appearance are good, electromagnetic shielding grade height, be suitable for batch process, cost low cost and other advantages.

The purpose of this utility model is achieved by the following technical solution: the rack that a kind of communication equipment is used comprises upper enclosure frame, lower enclosure frame, column, side plate, Qianmen, back door and top cover; It is characterized in that the place, four angles of lower enclosure frame is provided with positioning boss respectively on described; Suitable position at column is provided with the groove that is complementary with the positioning boss that encloses frame, also is provided with some mounting grooves simultaneously; Described side plate, Qianmen and back door are connected by the installation nut strip screw that inserts in described mounting groove; Described upward lower enclosure frame utilizes described positioning boss to insert described groove with column and directly closely is connected; Described top cover utilizes screw to be installed on the upper enclosure frame.

Aforesaid the utility model rack is based on section bar and die casting is its basic framework, by adopting dormant bolt that the Upper/Lower Enclosure Frame and the section bar column of integral die-cast are connected to an integral body, constitute the basic framework of rack, this frame mode has the advantage that conveniently succinct and accurate positioning are installed; Because it is few to constitute the amount of parts of skeleton, and they need not by manual operation operations such as welding, polishings, so have the advantage that production process is simple, cost is low.Good, the standard degree height of each parts interchangeability can be realized respective procurement when assembling simultaneously, reduces and manufactures and cost of transportation.Enclose frame and adopt mold integral die casting to form, have the outward appearance high conformity, structural rigidity is strong and pinpoint advantage.Column adopts the aluminium section bar moulding, simple in structure, size and accuracy of form and position height.The last lower enclosure frame, column that constitute the rack basic framework be by die cast, and the following process amount is few and be easy to realization.In conjunction with the processing technology scheme of careful appearance and modeling scheme, succinct structural design and structure mounting means, optimization, unique process of surface treatment scheme and perfect electromagnetic shielding interface etc., make this rack reach high-quality, high grade requirements.

Below in conjunction with drawings and Examples the utility model and prior art are compared, and the utility model is further elaborated.
