Description
Technical field
The present invention relates to a kind of electric connector, is that a kind of floating blind plugging is from short circuit rectangular electric connector specifically.
Background technology
Along with the progress in epoch, the development of society, modern electronic technology, towards intellectuality, modularization, automation and microminiaturized future development, is therefore had higher requirement to electric connector.Equipment component be prevent mistake energising bring needn't consequence, require, before not switching on and using, between circuit, to present short-circuit condition, realize the protection of circuit by connector from short circuit.If the patent No. is the electric connector of 201320020751.0 disclosed a kind of short-circuit protections, pin part is provided with insulation division, short-circuit spring leaf is arranged in plug panel, elastic component promotes plug panel makes short-circuit spring leaf be adjacent to contact pin part also by all contact pin part short circuits, socket promotes plug panel makes short-circuit spring leaf move to insulation division releasing short-circuit condition, although contact short circuit function when can realizing the front short circuit of plug grafting and pegging graft, but its short-circuit spring leaf is clamped on contact pin part or insulation division and is slidably connected back and forth, short-circuit spring leaf easily causes the frictionally damage to contact pin and insulation division, after long-term use, contact pin and insulation division are fragile, affect short-circuit capability and contact pin transmission performance.
Separately have, existing domestic electric connector cannot meet on machining accuracy and Product Precision simultaneously, the deficiency that must make up by increasing floating installation precision realizes plugging together smoothly of connector, and floating installation has increased manufacturing cost and installation difficulty, is not easy to peg graft and use fast.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of compact conformation, manufacture, easy to use, cost is low, the wearing and tearing that can effectively avoid long-term plug to cause, increase the service life, guarantee that the floating blind plugging of short-circuit capability and connector transmission performance is from short circuit rectangular electric connector.
The technical solution used in the present invention is: a kind of floating blind plugging is from short circuit rectangular electric connector, comprise casing, seat housing, contact pin, contact pin insulating part, jack, jack insulating part and short board, short board is connected to elasticity on contact pin and inside short board and pushes against contact pin insulating part, its technical characterstic is that on described contact pin, cross-under has length to be not more than the back stop of short board thickness, back stop and short board are at short board apart from the complete contact short circuit plate of contact pin insulating part maximum flexibility deployed position connection status, and pin diameter is less than the aperture in the hole of short board cross-under contact pin.
Further, the elastic shrinkage amount that described short board pushes against contact pin insulating part is greater than short board thickness.
Further, on the contact pin between described short board and contact pin insulating part, be socketed with insulator, insulator external diameter is not more than the aperture in the hole of short board cross-under contact pin.
Further, described short board inner side vertically arranges screw rod, contact pin insulating part is provided with pilot hole, screw rod grafting guiding corresponding to pilot hole, on screw rod, be connected with the spring one end arranging along screw axial, the spring other end pushes against in contact pin insulating part towards short board one side side or pilot hole bottom face.
Further, described jack insulator along seat housing shaft to and/or radial elastic spacing.
Again further, the inside and outside chamber opening part circular arc chamfering that described casing and seat housing plug together mutually, corner limit, the inside and outside chamber circular arc chamfering that casing and seat housing plug together mutually.
Compared with prior art, advantage of the present invention is:
1, when casing does not plug together housing, short board is in the maximum flexibility deployed position apart from contact pin insulator under screw rod and spring action, and the back stop cross-under on contact pin becomes connecting contact pin and short board state in short board, and casing is short-circuit condition, when casing plugs together housing, short board overcomes spring action by screw rod guiding and moves towards contact pin insulator, on contact pin, back stop is thrown off and the contacting of short board, the corresponding gap of contact pin is connected in short board simultaneously, casing is non-short-circuit condition, contact pin plugs together jack, short-circuit function plugs together with connector and removes, and plugging together recovery automatically after separation, thereby realize the short-circuit protection of electric connector, the short-circuit function of short board only realizes at back stop position, continue in the process through short board at contact pin, contact pin does not contact with short board, contact pin not damaged, short circuit and the serviceability of electric connector are guaranteed, be conducive to extend the useful life of electric connector, on contact pin, be socketed insulator, the short circuit in the time that electric connector plugs together contacts with short board effectively to avoid contact pin, further guarantees serviceability.
2, in the time that casing and a seat housing correspondence plug together, the round and smooth guiding of inside and outside chamber opening part circular arc chamfering energy that casing and seat housing plug together mutually, cooperating head housing and corner limit, the inside and outside chamber circular arc chamfering that mutually plugs together of seat housing, realize blindmate, the anti-misplug function of electric connector; Jack insulator along seat housing shaft to and/or radial elastic spacing; Adjust insulator by elastic spacing and realize free floating with the fit clearance of seat housing, guarantee plugging together smoothly of connector assembly, further improve blindmate convenience.
