Abstract
The utility model relates to a mechanical self-locking disposable electric plug provided with a switch. The plug includes a fixing pin, a movable pin, a conductor spring, an extension spring, a rotating shaft and a housing. The movable pin is provided with a limiting groove and a self-locking groove. The movable pin is fixed in guiding grooves in the housing via a limiting column in the limiting groove. A non-conductor linkage rotating rod is fixed in the housing via the rotating shaft. The conductor spring is fixed on one end of the non-conductor linkage rotating rod, and the end is connected with the extension spring in the housing. The other end of the non-conductor linkage rotating rod contacts with a side face of the movable pin and tightly clings to the side face of the movable pin under the pulling force of the extension spring. The conductor spring on one end of the non-conductor linkage rotating rod is separated from the upper end of the conductor spring via a clip type groove on a toggle switch. The mechanical self-locking disposable electric plug provided with the switch has the characteristics of high reliability, simple technology, and high cost performance.
Description
Technical field
The utility model relates to a kind of disposable plug of mechanical self-latching type that can effectively guarantee the disposable belt switch of plug.
Background technology
Disposable electric plug connector is widely used in all kinds of electric interfaces to disposable requirement.But in the existing disposable power plug configuration, have certain defective: it is unreliable to contact, and easily produces misoperation, and the moving width of cloth of moving pin is large, and moving pin easily comes off, rotates when extracting, and excessive etc. to the external form change of plug.
Summary of the invention
The purpose of this utility model has just provided a kind of disposable plug of mechanical self-latching type of simple in structure, with low cost, belt switch that reliability is high.
The disposable plug of the mechanical self-latching type of belt switch of the present utility model, comprise fixed piece on earpiece, moving pin, the conductor shell fragment, extension spring, rotating shaft, shell, have the spacing-type groove on the moving pin, the self-locking groove, moving pin is by in the fixing gathering sill in the enclosure of the limited post in the spacing-type groove, non-conductor interlock bull stick is fixing in the enclosure by rotating shaft, the conductor shell fragment is fixed on an end of non-conductor interlock bull stick, extension spring in this end and the shell is connected, the other end and the moving pin contacts side surfaces of non-conductor interlock bull stick, be close on the moving pin side at this end under the pulling of extension spring, the pincers type groove by toggle switch between the conductor shell fragment of non-conductor interlock bull stick end and the moving pin upper end separates.
The disposable plug operation principle of the mechanical self-latching type of belt switch of the present utility model is, before the use, the conductor shell fragment is separated by pincers type groove with moving pin and do not contact, and circuit is in off-state, and the pincers type groove on this moment toggle switch blocks moving pin fixes it.During use, plug inserts socket, and the limited post on the shell blocks the anti-stop pin of moving pin at the upper/lower positions that moves pin spacing-type groove and is absorbed in the plug, toggle switch is opened, pincers type groove on the toggle switch breaks away from moving pin, and the conductor shell fragment contacts circuit communication with moving pin.After plug work is finished, when plug is extracted from socket, moving pin moves along the gathering sill on the shell, non-conductor interlock bull stick and conductor shell fragment fixed thereon rotate around the axis under the pulling of spring, non-conductor interlock bull stick snaps in the self-locking groove of moving pin, simultaneously the upper position that moves to moving pin spacing-type groove of the limited post on the shell is blocked the anti-stop pin of moving pin and is come off, the conductor shell fragment breaks away from moving pin, circuit disconnects, and can't return to conducting state, thereby reach disposable effect.
The disposable plug of the mechanical self-latching type of belt switch of the present utility model has the reliability height, and technique is simple, the characteristics that cost performance is high.
