Abstract

The utility model discloses a lamp socket which comprises a socket core, a socket tube and an inner core, wherein the socket core is sealed with the inner core and the socket tube by mechanical principles. Therefore, the leak current is smaller than 0.5mA, the electric potential is smaller than 21.1V, and the utility model prevents the phenomenon such as injuries and fire disasters caused by electric conduction when rain water enters the utility model, etc.; meanwhile, the utility model adapts to the new standard of No. 17 version of UL588 which is posed by the American UL safety test center to be executed in January 1, 1997.

Description

Lamp socket

The utility model relates to the lamp socket in a kind of UL lamp string.

In recent years, lamp string as decoration function mainly is to beautify environment confession in red-letter day people to view and admire, it is American States such as main that domestic UL lamp string is wherein sold in a large number with the U.S., but the anti-electric leakage of existing product waterproof ability is poor, product service life is short and easily cause electric leakage to hurt sb.'s feelings and burn, particularly propose to play the new standard that will carry out UL588 the 17 edition on January 1st, 97 at U.S. UL safety test center in 1996, original product just can not be suitable for new standard.

Main purpose of the present utility model is to improve the prior art shortcoming, provides a kind of leakage current less than 0.5mA, and electromotive force makes the lamp string can effectively prevent the safety lamp holder that rainwater enters when outdoor application less than 21.1V.

Art designs scheme of the present utility model is: it is made up of slotting stamen, interior stamen, intubate, insert stamen and be made of bulb and pin, slotting stamen, interior stamen, intubate are made into wedge type, and the upper end is big, the lower end is little, inserting stamen and interior stamen can only insert from the upper end of intubate, make the fit sealing that combines of inserting stamen and interior stamen and intubate, simultaneously, the first half of interior stamen is a circle, and a pair of slot is set, a pair of inside groove is set again in slot, and the Lower Half of interior stamen is a rectangle, and the semi-circular arc groove is made in wherein corresponding both sides.The intubate first half is circular, the wherein corresponding both sides of Lower Half are inwardly cut and are into become level and smooth, make it form a card knot at inwall, at both sides, about 2-3cm place formation semi-circular arc groove from the lower end, and constitute a tube chamber with the Lower Half arc groove of interior stamen, terminal line is passed through just and sealing tube chamber port, in the inside groove in the copper sheet on the terminal line just in time is inserted on the stamen.

In sum, lamp socket of the present utility model adopts technique scheme, make between slotting stamen, interior stamen, the intubate and to cooperate and utilize the theory of mechanics sealing, make the lamp string when outdoor application, can reach leakage current less than 0.5mA, electromotive force is less than 21.1V, thereby avoids increasing resistance and making on fire and charged the hurting sb.'s feelings of lamp socket heating because of rainwater drenches, and also prolongs product service life simultaneously.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

With reference to Fig. 1, lamp socket of the present utility model is made up of slotting stamen 2, interior stamen 7, intubate 8, insert stamen 2 and comprise bulb and pin 3 two parts, on the stamen 7 in the end slot 71, a cavity 4 is set in pin 3 in pin 3 just in time is inserted in, make the lamp base copper wire of bulb 1 pass cavity 4 and left-hand thread in pin 3 outsides, during stamen 7, copper wire just in time connects and rides on the copper sheet 5 in slotting stamen 2 inserts, and 8 of interior stamen 7 and intubate are at bottom formation tube chamber 9, terminal line 6 is passed through just, and tightly wale.

With reference to Fig. 2-shown in Figure 3, intubate 8 is designed to the cavity of wedge shape both ends open, middle in intubate 8 to end portion, corresponding tube wall is wherein inwardly cut into, form a card knot 82, stamen 7 upper end circular portions just in time block in making, at about 2-3cm place intubate 8 both sides inwalls formation semi-circular arc grooves 81 from the lower end.

With reference to Fig. 4-shown in Figure 6, interior stamen 7 upper ends are for circle and a pair of slot 71 is arranged, inside groove 72 is set in slot 71, the termination copper sheet 5 of terminal line 6 just in time is embedded in the inside groove 72, at interior stamen 7 lower semisections is rectangle, wherein both sides form semi-circular arc groove 73, and coincide into tube chamber 9 (as shown in Figure 3) with semi-circular arc groove 81 in the intubate 8.

Like this, lamp socket of the present utility model is when assembling, and terminal line stretches into from intubate 8 bottoms, inside groove 72 in copper sheet on the end points embeds in the stamen then catches terminal line firmly to be pulled outwardly, and stamen 7 tightens together with intubate 8 in making, then, slot 71 in the stamen 7 in slotting stamen 2 insertions is got final product.

Claims
