Background technology
In the prior art, usually use the identical printed circuit electric connectors of many covers in equipment, this requires electric connector to have guiding and anti-misplug function, realizes guiding and location by locating guide device when plugging together, and misplugs preventing.At present, the public locating guide device (guide finger) that is fixed on straight formula electric connector (mostly being socket) mainly is fixed in the insulator of straight formula electric connector by nut; The female locating guide device (fairlead) that is fixed on curved formula electric connector (mostly being plug) mainly contains two kinds of structures: the one, screwed hole is left on the fairlead top, and adopt screw to be fixed on the electric connector insulator from parallel printed circuit board direction; The 2nd, drill through the hole in the fairlead side of regular polygon (square, regular hexagon and octagon), be fixed on the electric connector insulator from vertical printed circuit board direction with screw, nut.These two kinds of structures respectively have deficiency, first kind of mode compact conformation, and connector overall dimension is less relatively, if curved formula electric connector has been welded in the printed board, the dismounting of fairlead, transposition be difficulty very, if be welded with other components and parts near the electric connector place, then first method is dismantled and replaced; Though the locating guide device of positive n limit shape has n
2Kind fixed bit combination because fairlead can not be dismantled and replace, has in fact only utilized a kind of location combination wherein, limited regular polygon the performance of locating guide device advantage, particularly increased the difficulty the when user overhauls equipment; The dismounting of the fairlead of the second way, transposition are conveniently, but need at the regular polygon flank hole, require the regular polygon size dimension enough big, cause the overall dimension of electric connector relatively large, to the electric connector of the locating guide device that uses regular hexagon and octagon, require printed board to have enough spaces that electric connector is installed especially.Along with science and technology development, electric connector develops to modularization, multicore number, high density direction, and is more and more tighter to the overall dimension requirement of electric connector, limited the use of the locating guide device of the second way.
Summary of the invention
The purpose of this utility model is intended to overcome deficiency of the prior art, by changing the fixed form of locating guide device in printed circuit electric connector insulator, thereby provide a kind of not only compact conformation of printed circuit electric connector that makes, and the dismounting of locating guide device, transposition are very convenient simple and direct, effectively improve the locating guide device of printed circuit electric connector of the serviceability of printed circuit electric connector.
Content of the present utility model is: a kind of locating guide device of printed circuit electric connector, to form by being installed in female locating guide device on the curved formula plug and the public locating guide device that is installed on the straight formula socket, and its feature part is:
Described female locating guide device is by the L type clamp (3) of the fairlead (2) in the dress people pin insulator, fixed guide cover (2), screw (4) and nut (6) and the spring washer (7) and packing ring (8) formation of fixed L type clamp (3);
Described fairlead (2) by an end have L type clamp (3) fixedly the outer peripheral face in the cylindrical sleeve (18) of the multidiameter of usefulness (17), the other end and the stage casing jacket casing (19) that is regular polygon constitute, on cylindrical sleeve (18) and the jacket casing (19) guiding straight trough (16) is arranged;
One end of described L type clamp (3) has U-lag (21), the other end on the multidiameter (17) that is stuck in fairlead (2) that the hole (20) that is socketed on the screw (4) is arranged.
In the utility model content: the regular polygon of described jacket casing (19) outer peripheral face can be square, regular pentagon, regular hexagon or octagon.
Compared with prior art, the utlity model has following characteristics:
(1) adopt L type clamp from curved formula plug side fixed guide cover, fairlead overall dimension is little, thereby the electric connector structure compactness, and overall dimension is less relatively; With screw L type clamp is fixed on the insulator, pulls down screw, arrive L type clamp down, can withdraw from fairlead, realize the quick and simple and direct dismounting and the transposition of fairlead, can make full use of the advantage of regular polygon positioning and guiding;
When (2) electric connector adopts orthohexagonal locating guide device, 36 kinds of location combinations are arranged promptly, the guide finger convex closure is consistent with the direction of fairlead guiding straight trough when plugging together, plug and socket just can plug together, earlier guiding, location when plugging together, after plug together, can effectively prevent to misplug;
(3) simple in structure, produce easily, easy to use, practical.
