Abstract

The utility model relates to an instant assembling lamp holder, which comprises a lamp holder shell body and a conductive body, wherein, the conductive body is composed of the conducting strips and the conducting screws of electrodes; the end head of the conducting screw has a sharp edge; a movable spanner knob for clamping electric wires is installed on the shell body. So long as toggling the spanner knob, the electric wire of a power supply can be clamped between the shell body and the end face of the spanner knob. The sharp edge on the conducting screw positioned in the shell body pierces the insulating sheath of the electric wires, and is contacted with a core wire; thus, the installation of the lamp holder is finished and is unusually quickly. The lamp holder is especially suitable for the installation of decorating color lamp bulbs.

Description

Instant assembling lampholder

The utility model belongs to lamp head, is specially the Instant assembling lampholder that is used to assemble the decorating lamp bulb in red-letter day.

Existing lamp holder is made of housing, cap, electric conductor and union piece.Wherein electric conductor is the conducting strip that contacts with bulb the two poles of the earth.One conducting strip is the reed shape, is positioned at the top of housing inner chamber, contacts with the firewire electrode of bulb head, and another conducting strip is the screwed pipe shape, is positioned at internal chamber wall portion, contacts with the middle line electrode of bulb head.Above-mentioned conducting strip is screwed on shell of lamp base.When bulb is installed, open the cap of lamp holder, to draw in lamp holder with a bit of twinax cable, two conducting strips are connected with an end of segment twinax cable in the lamp holder, and the other end is connected with the external power electric wire respectively.When connecting above-mentioned lead, remove the insulation sheath of lead, the terminal place will seal with insulating tape.So when above-mentioned lamp holder was installed, very tired lock was installed time-consuming.

The purpose of this utility model is to design a kind of lamp holder of avoiding the energy Fast Installation of above-mentioned tired lock operation.

The utility model also comprises shell of lamp base, electric conductor.Wherein electric conductor is made of two electrodes conduct sheets and the contact screw that is fastenedly connected with it respectively, and there is sharp sword said contact screw termination, and the portable plate that the chucking electric wire is housed on the said shell of lamp base is turned round.This is pulled to turn round with brace, packing ring, reed and is assemblied on the shell of lamp base.Have pulling the projection of twisted commentaries on classics location in the termination of shell of lamp base.

When this lamp holder is installed, as long as two wires are placed the sharp blade of electric light contact screw respectively, pull and turn round, two electric wires can be clamped on shell of lamp base and pull and turn round between the lower surface, dress is fixed in the perverse insulating covering of wearing lead of the sharp sword of contact screw on the shell of lamp base, contact with heart yearn, lamp holder can install.

Fig. 1 is the utility model embodiment elevation cross-sectional view, and book extract accompanying drawing as an illustration;

Fig. 2 is the vertical view of embodiment 1, and A-A presentation graphs 1 analyses and observe direction among the figure;

Fig. 3 is the end view of embodiment 1;

Fig. 4 is the elevation cross-sectional view of the utility model embodiment 2;

Fig. 5 is the elevation cross-sectional view of the utility model embodiment 3.

Further specify below in conjunction with accompanying drawing.

See Fig. 1, Fig. 2,9 is housing, moulds system with bakelite, and molding has nut 6 in the housing, contact with bulb two electrodes electric conductor as follows: a route conducting strip 7, trip bolt 5 constitutes, and screw 5 is fastened on conducting strip 7 on the shell of lamp base 9; Another route screwed pipe shape conducting strip 8 and trip bolt 10 thereof constitute.There is sharp sword contact screw 5,10 ends.Conducting strip 7,8 contacts with bulb live wire, middle line electrode respectively.Screw 5,10 is separately fixed in the nut that is molded into housing.Pull and turn round 4, arc spring leaf 3, packing ring 2 pass brace 1 successively, will pull to turn round 4 and be loaded on the housing 9, pulls to turn round 4 and can rotate, and survive movingly between the housing 9, and bossing 11,12 is arranged in the upper surface of housing 9, turns round 4 rotational positioning to pulling.Bossing 11,12 one-tenth are L shaped, become symmetric position with central shaft, as shown in Figure 3.Pull to turn round between 4 lower surface and housing 9 upper surfaces certain interval is arranged.Brace 1 can become I-shaped or adopt the riveted joint mode.There are two grooves the upper end of housing 9, and contact screw point blade is loaded in the groove.Turn round 4 when pulling to vertical orientations when pulling, two grooves expose, and are put in two grooves as long as will connect the electric wire of external power, pull then and turn round 4 to horizontal level, as Fig. 1 position, lead 13,14 are clamped in the groove.The perverse wire insulation skin of wearing of sharp blade of contact screw 5,10 contacts with conductive core line at this moment, and lamp holder is installed and promptly finished.So install quick and convenient, saving of work and time.Turn round 4 lower surface and also can design two projectioies in order to make contact more reliable, to pull, lug boss just in time aligns with above-mentioned groove, as shown in fig. 1.

Embodiment 2: above-mentioned conducting strip 7,8 and fastening contact screw 5,10 thereof are designed to one respectively, and its upper end also has sharp sword, and the upper end is molded in the housing 9, and all the other structures are identical, as shown in Figure 3.

Embodiment 3: the utility model also is suitable for socket bulb.This moment is as long as make the form of live wire conductive 7 with embodiment 1 or center line conducting strip 8 and the conduction trip bolt 10 thereof implemented in 2, and increases the light bulb socket cutting ferrule and get final product, as shown in Figure 4.

Claims

1, Instant assembling lampholder comprises shell of lamp base, electric conductor, and wherein electric conductor is made of electrodes conduct sheet 7,8 and the contact screw 5,10 that is fastenedly connected with it respectively, it is characterized in that there is sharp sword said contact screw 5,10 terminations; On the said housing 9 Flexible spanner that clamps electric wire is housed and turns round 4.
