According to the insertion connection line lamp holder disclosed by the invention, a power line is connected, produced and installed conveniently and rapidly; the connected power line is difficultly disconnected; the use process is safer; and the installation working efficiency is high.

Description

The patch lamp holder that has rotating switch

Technical field

The present invention relates to a kind of lamp holder, particularly relate to a kind of patch lamp holder that has rotating switch.

Background technology

The power lead of traditional lamp holder switch input generally adopts the screw lead, connect trouble, installment work efficient is low, internal core print seat is not set, inadequately safety, complex structure, work is stable inadequately, the long easy loose contact of lamp holder contact time, and traditional lamp holder loam cake, lower cover and bulb socket often are connected and fixed by screw, short circuit easily, packaging efficiency is low.

Summary of the invention

Purpose of the present invention just provides a kind of patch lamp holder that has rotating switch, and is convenient and fast connection, and installment work efficient height uses safelyr, and rotating construction of switch is simple, working stability.

For achieving the above object, the present invention adopts following technical scheme:

A kind of patch lamp holder that has rotating switch, comprise: bulb socket, the lamp contact, loam cake, lower cover, inner core, in-core is provided with rotating switch in the described lamp holder, the corresponding both sides of the switch swing handle axle of rotating switch are provided with the projection of drawing, projection is provided with the rectangle contact block, the lower end of rectangle contact block is provided with the V-arrangement shell fragment, the V-arrangement shell fragment connects the lamp contact chip and is fixed on the bulb socket, the upper end of rectangle contact block is provided with the switch contact, switch contact and plug wire contact are connected as a single entity, another plug wire contact is connected with another lamp contact riveted, bulb socket and inner core and protecting cover are connected as a single entity, and lower cover is threaded with loam cake by the bulb socket boss of bulb socket, and interior in-core is provided with two plug wire contacts, its plug wire contact is a shell fragment, is separately positioned in two plug wire hole inboard aperture of inner core upper side.

Described bulb socket and inner core, protecting cover are connected as a single entity by rivet.

The elastomer portions of plug wire contact of in-core setting is divided into right angle that shell fragment is converted into or the shell fragment that approaches the right angle in described, elastomeric upper side is connected with the contact of plug wire hole inboard aperture wall or near the inboard aperture wall, the plug wire contact jaw of elastomeric upper side is provided with the surface groove at band angle.

Described inner core upper side is provided with two wire-hanging hooks, and its hook is " C " frame, and the inside upper part face of " C " frame is respectively arranged with arc surface, and the height of the medial surface of the opening of the inboard of " C " frame and " C " frame is less than the height in the middle of " C " frame.

Beneficial effect of the present invention:, make switch activated more stable, and easy for installation because the projection on the corresponding both sides of the switch swing handle axle of rotating switch is provided with the rectangle contact block; Owing to be provided with the V-arrangement shell fragment in the lower end of rectangle contact block, not only guaranteed enough contact elastic force, the lower end is connected with the direct riveted of contact chip simultaneously, is difficult for displacement, makes service behaviour more stable, and a step is installed two parts, and installation effectiveness improves; Owing to be provided with the grafting contact, the connection power line directly inserts wire guide with the metal part of lead and gets final product, convenient and fast connection, difficult drop-off, plug wire contact jaw are provided with the surface groove at band angle, and lead inserts easily, be difficult for slippage, use safelyr, installment work efficient height is after the metal wire head end of power line inserts, the elastomer displacement of plug wire contact is less than an angle of 90 degrees, owing to be shell fragment, give thrust of electric wire all the time, because the angle of plug wire contact diminishes, the stressed direction of the direction that makes the electric wire slippage and shell fragment is opposite, even the outside slippage of electric wire can only be drawn tighter and tighter, thereby this structure is more safe and reliable; Because loam cake, lower cover and bulb socket are connected as a single entity and are not screwed, circumscripted power line is difficult for electric wire displacement when installing, and is difficult for the lead-in wire short circuit that causes damage, and is easy to assembly quick; Draw tighter and tighter because the height of the medial surface of the opening of " C " frame and frame less than the height of centre, makes the power line of introducing snap in, the difficult drop-off displacement.
