The utility model is characterized in that the upper surface of the supporting guide rail is provided with insertion guide grooves, both sides are symmetrically provided with connecting insertion grooves, both ends of the supporting guide rail are connected with the end connecting heads and the end connecting heads are sheathed with the supporting guide rail through insertion seats on one side of each of the end connecting heads. When the utility model is used, the length of the supporting guide rail can be determined according to requirements and the depth of a machine disk and then both ends of the supporting guide rail are sheathed with the end connecting heads to form the guide rail in which a printed circuit board can be inserted. The utility model is characterized in that the whole guide tail has few components, the splicing is convenient, the rigidity of the guide rail is favorable, and after the supporting guide rail is inserted into the end connecting heads, the connection of both ends is firm; the service performance is flexible, the universality is strong, and the guide rail can be suitable for machine disks with various depths; the width of the supporting guide rail is small, and the supporting guide rail is made of aluminium alloy and has a circular arc face structure on the lower surface, which is helpful to heat conduction and heat radiation.

Description

A kind of printed circuit panel guide that is used to peg graft

Technical field

The utility model relates to a kind of guide rail that printed circuit board (PCB) is installed in the grafting of machine dish that is used for.

Background technology

Existing grafting printed circuit panel guide has integral type and spliced two types, and the integral type guide rail is the plastic compression structure, and installation dimension is fixed, and is only applicable to a kind of depth gear dish, because plastics rigidity is lower, and easy deformation when guide rail size is big.Spliced guide rail two ends are the plastic compression structure, and the centre mostly is section bar, and connecting method mainly contains two kinds at present, and a kind of is that two ends plastic compression structure is inserted in the hole of intermediate proximate matter, and this guide rail is relatively poor in the intensity of splicing place; Another kind is to insert the two ends plastic pressuring piece again behind the intermediate proximate matter overcoat draw-in groove element, forms guide rail, and this guide rail component is more, splice loose, the structure relative complex, intermediate proximate matter only plays booster action, rail length is limited by the section bar outer jacket parts, thereby uses installation convenient inadequately.

Summary of the invention

Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and provide that a kind of member is few, splicing is easy firmly, connect good rigidly, is suitable for the grafting printed circuit panel guide of various depth gear dishes.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: include two end connectors 1 and support rails 2, its difference be described support rails above offer grafting guide groove 3, bilateral symmetry is offered and is connected slot 5, the two ends of support rails are connected with end connector 1, and end connector socket-connects with support rails by the plug socket 13 of one side.

Press such scheme, described support rails 2 is a uiform section body guide rail, and the cross section of wherein said grafting guide groove 3 is a rectangle, and connection slot 5 cross sections of both sides are trapezoidal, and the following of support rails is arc surface 8; Described support rails can be made by aluminium alloy.Described end connector 1 is made of fittings body 10 and plug socket 13, plug socket is arranged on a side of fittings body, which is provided with side and following suitable inserting groove 14 with support rails, be provided with the guiding groove 9 that is connected mutually with support rails grafting guide groove above the fittings body; The end connector structure left-right symmetric at two ends, the left and right sides.

The utility model can intercept the length of support rails as required with the degree of depth of machine dish when using, two ends and the end connector with support rails socket-connects then, promptly forms the guide rail of the printed circuit board (PCB) of can pegging graft.

The beneficial effects of the utility model are: 1, whole guide rail component is few, splice easy, the good rigidly of guide rail, two ends are connected firmly behind the support rails insertion end joint; 2, serviceability is flexible, and highly versatile is applicable to the machine dish of the various degree of depth; 3, the width of support rails is little, and adopts aluminium alloy and following arc surface structure, helps heat conduction and heat radiation.
