Abstract

The utility model relates to an electric blade lock core switch plug, comprising a blade lock core, a contact strip, the main seat of a switch lock and a wire holder. The blade lock core and a contact seat are made into an entity, and two sides of the contact seat are provided with elastic fins forming an inversed hook shape. The fins are clamped in a locating slot under a step bulge ring in a containing cylinder at the lower part of the main seat of the switch lock. The contact strip is sheathed with a small convex shaft under the contact seat. A contact at the lower part of the contact piece and the top contact of the wire holder are mutually contacted or separated with the rotation of the lock core, and thus the aim of switching the electrical plug via a key to switch on the plug or block electric current is obtained. The utility model has simple structure, good conductivity, firmness and durability, and the lock core rotates stably.

Description

Blade core-locking switch plug

The utility model relates to a kind of blade lock core formula switch plug.

The general now blade lock core formula switch plug 20 that uses, shown in Figure 10,11, be to be equipped with on the vane type lock core 22 under spring action, when the insertion key is made on-off action, do not produce the locating blades 221 of left and right displacement, all locating blades 221 all embed in the blade seat 220, with descend most on the sheet locating blades 221 corresponding switch lock seat of honour 21 pedestals 210 inwalls, do not have concave ring groove 211, the 211 interior vane type lock core is combined with the switch lock seat of honour 21 are fixed thereby locating blades 221 promptly embeds concave ring groove.This lockset open and close the action positioner be on the contact seat 230 of contact arrangement 23, be embedded one group of positioning ball 24 and spring 25, when opening and closing rotation in the key insertion vane type lock core 22, positioning ball 24 is under spring 25 effects, be that flush switch is locked containing on tube 212 inwalls of seat of honour pedestal 210, location in default vertical V-type groove 213 reaches and opens and closes the motionless purpose in location in the action.

This plug has following shortcoming:

1, seat of honour pedestal 210 inboard set concave ring grooves 211, because of must with lock core blade seat 220 descend sheet locating blades 221 corresponding most, so be deep into the stage casing of seat of honour pedestal 210, processing is difficulty relatively, the cost height, one is careless slightly, can seat of honour pedestal car is disconnected, or when installing and using, rupture easily.

2, the positioning ball in the positioner 24 during installation, must be pressed in the contact seat 230 of contact arrangement 23, could be with contact seat 230, and switch lock seat of honour pedestal 210 hypomeres of packing into contain in the tube 212, and one is careless slightly.Positioning ball 24 will eject and drop, so assembling inconvenience, work efficiency is low; Again when lock core drive contact strip 231 opens and closes rotational action, because of 230 of contact seats have spring 25 to support in a side, to lopsidedness, cause two contacts 232 on the contact strip 231 closely to contact easily, cause the conduction loose contact with two junction poles, 261 tops on the junction block 26.

The purpose of this utility model is that a kind of improved blade lock core switch plug will be provided, and it is simple in structure, and is easy to assembly, handling ease, and the break-make performance is good.

The purpose of this utility model is achieved in that this blade lock core formula switch plug, by the vane type lock core, contact strip, the switch lock seat of honour, junction block constitutes, vane type lock core and contact seat are integrally molded, the contact seat both sides are provided with overhead kick shape elastic fin, this fin is stuck in the switch seat of honour bottom of unblanking and contains in the tube in the location notch under the prominent ring of set stratum, contact strip is enclosed within on the little protruding axle under the contact seat, with contact under the rotation contact strip of lock core and the top contact on the junction block, be in contact with one another or break away from, thereby reach with the key switch plug, make plug connect or cut off the purpose of electric current.Its advantage is:

1, simple in structure; Processing easily, assembling is easy: because of the vane type lock core combines with overhead kick shape elastic fin with seat of honour pedestal, so assembling is easily; It is integrally molded that the blade seat of vane type lock core and contact seat add man-hour, so simplify the structure; In addition, in seat of honour pedestal, concave ring groove must be set, handling ease can more not improve robustness because of car system concave ring groove ruptures.

2, good conductivity; Combine with a pair of overhead kick shape elastic fin because of between lock core and seat of honour pedestal, and fin is embedded in the V-shaped groove locate, so but balance and stability ground drives the contact strip rotation, the realization switch motion, and make the contact close proximity.

Describe in detail below in conjunction with accompanying drawing,

With reference to Fig. 1-9, this blade lock core formula switch plug 10 is made of vane type lock core 12, contact strip 13, the switch lock seat of honour 11, junction block 15.

The blade seat 120 of vane type lock core 12, make by tough plastic materials, its lower end and contact seat 121 are directly integrally molded, contact seat 121 lower end central authorities are provided with little prominent axle 122, on the little prominent axle 122, be with spring 14 and contact strip 13, contact seat 121 both sides are provided with the elastic fin 213 of a pair of overhead kick shape;

Contact strip 13 both sides are provided with the fin 132 of projection, and this fin 132 embeds both sides, contact seat 121 lower end and reserves in the pit 125, and contact strip 13 other both sides are provided with the contact 131 to lower convexity;
