Abstract

The utility model relates to an improved safety lighting lamp and a lamp socket. When in use, the utility model avoids short circuits of the circuit, broken circuit and electric shock from occurring. The improved lamp end is provided with an insulator with two antennas. The contacts of the circuit are fixed on the antennas. The inner wall of the jack of the lamp holder is provided with arranged open grooves and closed grooves, and the open grooves and closed grooves are communicated through a passage. The circuit is arranged in the closed grooves. A bottom disc is provided with a fixed spring which is arranged in the jack. When in use, the antennas of the lamp bulb are inserted into the lamp holder from the open grooves and are rotated into the closed grooves in a definite angle. The antennas of the lamp bulb are pressed in the bottom of the closed grooves through the elasticity of the spring. The circuit is connected by the contact.

Description

Safety lighting lamp and lamp socket

The utility model is improved incandescent lighting electric light and lamp socket, and no matter bulb is being pacified, when unloading, can not got an electric shock to use this lamp, also avoids lamp socket circuit breaker and short circuit simultaneously.

Existing incandescent lamp has two kinds of spiral and bayonet types, wherein bayonet type is that two contacts by two copper posts in the lamp socket and light bulb base are connected, and spiral be king bolt cover in the lamp socket, the curved shape copper sheet in bottom respectively with the contacting at bulb metalized lamp tail top, and one requires the copper post to be connected with the contact tightly, if any error, just open circuit.And copper sheet compressive deformation in the spiral lamp socket, can not contact bulb contact opens circuit, and opposite copper sheet contact helical casing is short-circuited again, and above-mentioned bulb tail adopts metal very easily to get an electric shock.

The purpose of this utility model is to adopt insulation lamp tail, in the straightway while of lamp socket electric current, electric conductor " hidden " in lamp tail and lamp socket, is avoided current interruption, short circuit and electric shock.

The utility model is finished in the following way: set up inboard wall of lamp holder separately two open channels and undercut, be equipped with spring in the center, chassis, conducting channel is positioned in the undercut, open channel and undercut are communicated with by the chassis with passage simultaneously.The lamp tail adopts insulator, and the haptic element of two symmetries is arranged, and two contacts of circuit are fixed on the haptic element.

When feeler dropped in the lamp socket undercut, circuit was described its structure and use by contacting in detail below in conjunction with accompanying drawing:

The utility model is simple in structure, and easy to use, reliable, safety almost do not increase product cost, and the economic benefit utmost point must be for considerable.

With reference to Fig. 2,3,4,5, insulating lamp holder jack inwall has two open channels (9) and the undercut (8) of symmetry.Undercut (8) length is less than open channel (9), and is communicated with at inwall by chassis (1) is stepped by passage (10) between the light and shade.Chassis breach (11) is aimed at undercut (8), is fixed on the shell internal orifice by hole (12).Spring (6) is fixed in the lamp socket on the chassis L type conductive copper sheet (2) by hole (13) and places undercut (8) to be drawn by breach (11) to connect outside line.With reference to Fig. 1, bulb is drawn the back casting by the insulation garden bucket of two haptic elements of sidepiece band (3) and foam under by haptic element (3) at lead-in wire (5) and is connect and form, and back lead riser is fixed on the haptic element (3) or hard contact (4), and Lingering Garden groove (7) is disclosed in the garden.

During use, lamp tail haptic element (3) is inserted at the end from lamp socket undercut (9), make spring (6) fall into light trough (7), rotation bulb 90 degree, haptic element (3) is gone into undercut (8) by passage (10), Song Li makes the elastic force of spring (6) that haptic element (3) is headed into undercut (8) bottom, and circuit (2) and circuit (5) are connected by contact (4) on the circuit at this moment.
