As the guide rail assembly of the utility model has less parts and simple assembly, the guide rail plate and the nut bar adopt tooling production with low cost and high production efficiency; the guide rail plate is made of metal materials and has good radiation performance, and can reduce the noise of fan, static is uneasy to produce between the guide rail plate and the printed board, even if static occurs, the static is uneasy to be discharged by the guide rail plate, no additional static discharge spring plate is needed so as to save the cost and simplify the working procedure, thereby enhancing the machining precision.
Description
Technical field
The utility model relates to responsibility system circuit board manufacturing technology, more particularly, relates to a kind of guide plate assembly.
Background technology
The standard based on the high-performance industrial bus of PCI standard that CPCI is that industrial computer manufacturer organizes to set up, the CPCI standard is a large amount of accepted standards of a kind of quilt in the communications industry.
Fig. 9 and Figure 10 shows that typical C PCI standard edge receptacle, comprise parts such as printed circuit board 14, Insertion panel 15, plug-in and pull-out device handle 10, in the CPCI standard, to each parts of edge receptacle: the version of printed circuit board, plug-in and pull-out device handle etc. and size have strict restriction.
Be to cooperate CPCI standard edge receptacle, the size of each parts of CPCI subrack is also had strict regulation.As Fig. 7, shown in Figure 8, the schematic diagram that combines with the CPCI subrack 16 of prior art for CPCI standard edge receptacle 17.The critical piece of CPCI subrack is plastic cement guide rail, aluminium section bar crossbeam, plastic cement guide rail cost height, and aluminium section bar crossbeam rigidity is relatively poor.And, 84 slots are arranged on the front end boss of aluminium section bar according to the IEEE1101.11 standard, all be the force part here during the printed circuit board plug, be very easy to distortion, and distortion is arranged slightly, the effect that the plug-in and pull-out device handle just can't be correct causes printed board to plug normally thereon.And the plastic cement guide rail need assemble the electrostatic leakage shell fragment, and static bleed off shell fragment need be assembled on the plastic cement guide rail, and the plastic cement guide rail needs again to be installed on the aluminium section bar crossbeam, the assembly relation complexity.Cause operation many, man-hour is long, also is not easy to guarantee precision.Anti-wrong plug key also is being installed on the end block being connected of plastic cement guide rail and edge receptacle, but in the practical application of product in the industry cycle, 20 have special anti-wrong plug key on 2 millimeters connectors of printed circuit board, its effect is more reliable.Therefore the plastic cement guide rail does not all use with anti-wrong plug keyed jointing mouth on being connected end block, causes waste.
The utility model content
This practicality provides a kind of guide plate assembly, to solve the low problem of complex structure, production and packaging efficiency that exists in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of guide plate assembly, guide plate assembly is made of guide rail plate and nut strip, and wherein, the guide rail plate comprises rail portion and crossbeam portion, and crossbeam portion and rail portion connect and compose the guide rail plate by securing member.
The utility model has the advantages that: the guide plate assembly part is few, makes assembling simple; Guide rail plate, shaped steel nut strip adopt mold production, and be with low cost, production efficiency height, machining accuracy height; Adopt steel material, rigidity is good, and is not yielding; The guide rail plate is a metal material, and perfect heat-dissipating can reduce fan noise, and be not easy to produce static between the printed board,, need do not installing the electrostatic leakage shell fragment in addition additional even there is static also to be easy to release by the guide rail plate, save cost, simplified operation, thereby also improved machining accuracy.
The utility model is described in further detail below in conjunction with drawings and Examples.
