Abstract
An anti-misplugging structure used for an electric connector comprises a guide sleeve assembly and a guide pin. The guide sleeve assembly comprises a guide sleeve and a spacing screw, wherein the guide sleeve and a lower end of the spacing screw are fixed in an installation counter bore of the socket housing of the electric connector; a step of the head portion of the upper end of the spacing screw is connected on an upper end of the guide sleeve in a pressing manner; a tail end of the guide pin is connected with the socket housing of the electric connector; a periphery of an upper end of the guide sleeve is provided with a boss; and eight outer positioning surfaces are circumferentially and uniformly distributed on the boss. An annular boss is distributed in the middle portion of the guide pin, and eight guide pin positioning surfaces are circumferentially distributed on the annular boss uniformly. The anti-misplugging structure has multiple functions such as guiding, anti-misplugging and fixing connectors, can satisfy requirements of quick assembling or dismounting connectors, is convenient for a user to freely adjust an anti-misplugging position, and can satisfy requirements such as on-site quick adjustments.
Description
Technical field
The utility model relates to a kind of misplug-proof structure for electric connector, and the avoiding misinsertion that is used between a plurality of same specification electrical connector plugs and the socket connects.
Background technology
In the interconnection of electronic circuit, often there are a plurality of connectors of same specification to be installed in situation on same panel or the same pcb board, in order to prevent wrong plug between connector, usually require connector to have the avoiding misinsertion function, such as the employing of 38999 cylindrical connectors is at plug and socket 5 keys/groove to be set, difference by key/angle of the v-groove realizes its avoiding misinsertion (angle strict conformance that namely only has key/groove on plug, the jack housing, just can achieve a butt joint, otherwise owing to having interference between key, the groove and can not docking interconnection, to reach the purpose of avoiding misinsertion).Rectangular products arranges the avoiding misinsertion that special avoiding misinsertion pilot pin or positioning key are realized the same specification product usually, adopt 3 hexgonal structure positioning attachments such as J16 series (GJB177A series) rectangular connector, 2mm series printed board connector adopts special avoiding misinsertion positioning attachment to realize avoiding misinsertion, etc., the products such as ZD and VITA Bussing connector arrange guide finger/cover, and realize avoiding misinsertion by at pcb board plane of orientation being set.
But also there are some defectives in these positioning attachments, and are high such as complex structure, cost, function singleness, be inconvenient to dismantle and maintenance, operate not convenient, waste time and energy in adjustment avoiding misinsertion position, dumb etc.
The utility model content
The purpose of this utility model is for overcoming defects, a kind of multifunction electronic connector misplug-proof structure simple in structure, easy to use is provided, satisfying instructions for use.
The scheme that the utility model adopts is:
Described misplug-proof structure for electric connector, comprise guide pin bushing assembly and guide finger, described guide pin bushing assembly comprises guide pin bushing and stop screw, described guide pin bushing and stop screw lower end are individually fixed in the installation counterbore and screwed hole of electrical connector plug shell, and stop screw upper end head step is crimped on the upper surface of guide pin bushing; The guide finger tail end links to each other with the electric connector socket shell, and described guide pin bushing upper end outer rim is provided with boss, and this boss is uniform 8 outside fix faces circumferentially, are provided with the shell aperture locating surface corresponding with described outside fix plane in the installation counterbore of plug body; Described guide finger abutting end anchor ring is provided with preposition locating surface, the middle part is provided with annular boss, uniform 8 the guide finger locating surfaces in annular boss border, jack housing is provided with location counterbore and the installing hole corresponding with the annular boss of described guide finger and tail end, is provided with the interior locating surface that cooperates with the preposition locating surface of guide finger in the endoporus of guide pin bushing.
The utility model possesses the several functions such as guiding, avoiding misinsertion and fixed connector, even if can satisfy rapid-assembling or the dismounting connector has been installed on the equipment, also still makes things convenient for the user arbitrarily to adjust the position of avoiding misinsertion, satisfies the needs such as on-the-spot rapid adjustment.
