Abstract
The utility model relates to a connection device for electric wires and lamp bulbs of a decorative lamp string, which comprises electric wires (1), a lamp base (2), a lamp bulb (3) and a sleeve pipe (4), wherein, the tail part of the lamp base (2) is provided with a hollow pipe; the middle part of the lamp base (2) is provided with a cylinder of which the both sides are provided with wire travelling grooves; the upper part of the lamp base (2) is provided with a clamping opening which can be loaded with a lamp bulb; the clamping opening is composed of two circular blades; the electric wires (1) are penetrated into from the tail part of the lamp base (2) to connect the lamp bulb on the clamping opening through the travelling grooves; the wire travelling grooves and the clamping opening are sheathed by the sleeve pipe (4) to function as fixing and insulation. The utility model with the improved structure has the advantages of large tensile strength and superior insulation performance.
Description
The utility model relates to the jockey of electric wire and bulb in a kind of decorative chain.
The lamp string is to adopt decorative lamp (seeing GB GB7000,9-1998 for details) in parallel or that be composed in series by several bulbs.The jockey of electric wire and bulb is its core texture in the manufacturing of lamp string, also is the core of design of lamp string and production technology.
The lamp series bulb of prior art is connected the most frequently used dual mode that has with electric wire, division is as follows:
First kind: electric wire and bulb lamp base are welded to connect, be inserted in a sleeve pipe at bulb tail, solder joint and electric wire near a fragment position of solder joint, end from electric wire injects glue in sleeve pipe, play preliminary insulation and waterproof effect, be inserted in heat-shrinkable T bush after the primary solidification again, play the effect of fixing and reinforced insulation after the contraction.This mode is because employing glue insulate, sleeve pipe reinforced insulation and fixing, thereby cost is lower, but its insulating properties is relatively poor, and mechanical strength is relatively poor.Often have bulb two lamp bases and bump the problem that together is short-circuited, the situation of casing collapse took place when electric wire was subjected to pulling force.National standard and American-European standard all the connection electric wire of regulation lamp base should be able to be born certain pulling force, and the situation of casing collapse often will take place under this pulling force this structure, thereby are a kind of products that is not easy to meet country or international safety standard.
The second way is first lamp socket of system, electric wire be fixed in the lamp socket after terminal is connected, cooperate lamp socket to make a lamp holder again, lamp holder is provided with the depression that supplies to adorn bulb, bulb is inserted in the lamp socket after being installed on the lamp holder again.The advantage of this device is to bear big pulling force, but bulb comes off easily, particularly taken off by child is free-hand easily, thereby do not meet 4,11 requirements of European IEC-598 standard, and cost is higher, and productivity effect is low.
The purpose of this utility model has been to provide the jockey of electric wire and bulb in a kind of lamp string, makes it to have stronger mechanical connection intensity, good electrical insulation properties and make characteristic of simple.
The purpose of this utility model is achieved in that
The jockey of electric wire and bulb in a kind of decorative chain, comprise electric wire, lamp socket, bulb, sleeve pipe, wherein electric wire penetrates walking in the line groove of lamp socket by the hollow tube of lamp socket lower end respectively, be connected with the lamp base of bulb again, bulb is stuck in the lamp socket bayonet socket, the lamp base of bulb is opened by the plastics entity separation between two troughs, is inserted in heat-shrinkable T bush in lamp socket middle-end and bayonet socket section, seals lamp socket middle part, bayonet part and bulb tail after heat-shrinkable T bush shrinks.
The jockey of electric wire and bulb in aforesaid a kind of decorative chain, it is characterized in that the lamp socket lower end is a hollow tube, middle-end is the cylinder that both sides have away line groove, walking line groove is connected with the lower end hollow tube, top is the bayonet socket of being made up of two circular arc limbs, and bayonet socket is walked line groove with two and is connected.
The utility model is simple in structure, and is easy to connect, has stronger mechanical connection intensity, good electrical insulation properties and security.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is one of lamp socket stereogram of the present utility model
Fig. 3 is two of a lamp socket stereogram of the present utility model
The utility model comprises electric wire 1, lamp socket 2, bulb 3, sleeve pipe 4.Wherein lamp socket 2 lower ends are hollow tube 5, and middle-end is the cylinder that both sides have away line groove 6, and both sides are walked line groove 6 and are connected with lower end hollow tube 5, and top is the bayonet socket of being made up of two circular arc limbs 7, and bayonet socket 7 is walked line groove 6 with two and is connected.Electric wire 1 hollow tube 5 by lamp socket 2 lower ends respectively penetrates lamp socket 2 and walks in the line groove 6, and electric wire 1 is connected with the lamp base of bulb 3 through walking line groove 6.As the welding etc.Connect the back bulb 3 that finishes and be stuck in lamp socket 2 bayonet sockets 7, lamp base is separated by the plastics entity 8 between two troughs.Be inserted in heat-shrinkable T bush 4 for 7 sections in lamp socket 2 middle-ends and bayonet socket, seal lamp socket 2 middle parts, bayonet part and bulb 3 some areas after heat-shrinkable T bush 4 shrinks.
Advantage of the present utility model is, after sleeve pipe shrinks, tightly seals electric wire 1 and lamp socket 2, bulb 3.Lamp socket 2 walk line groove 6 and 1 very big frictional force of generation of electric wire, electric wire 1 is not easy to be pulled, and the afterbody of lamp socket 2 is plastics of hard, when two wires pulling separately, active force is applied to the lamp socket afterbody, is not to act directly on the sleeve pipe 4.Thereby do not have the problem of pulling open sleeve pipe 4, and because sleeve pipe 4 has encased bulb 3 somes, bulb 3 is not easy to be drawn out of, two lamp bases owing to bulb 3 are separated by the entity 8 between 2 liang of grooves of lamp socket again, thereby can not produce short circuit.
Claims (2)
1, the jockey of electric wire and bulb in a kind of decorative chain, comprise electric wire (1), lamp socket (2), bulb (3), sleeve pipe (4), wherein electric wire (1) penetrates walking in the line groove (6) of lamp socket (2) by the hollow tube (5) of lamp socket (2) lower end respectively, lamp base with bulb (3) is connected again, bulb (3) is stuck in lamp socket (2) bayonet socket (7), the lamp base of bulb (3) is separated by the plastics entity (8) between two troughs, be inserted in heat-shrinkable T bush (4) in lamp socket (2) middle-end and bayonet socket (7) section, seal lamp socket (2) middle part after heat-shrinkable T bush (4) shrinks, bayonet part and bulb (3) afterbody.
