Abstract
The utility model discloses a lamp head for a lamp string, belonging to the field of decorative lamps. The lamp head comprises a light source and a wire electrically connected with the light source, wherein, the wire is respectively directly fixed on two pins of the light source; an isolation column is arranged between the two pins for electrically isolating the two pins; and a protection housing is arranged at the lower end of the light source for covering the pins and a portion of the wire and for integrating the light source, the pins and the wire as a whole. Since the wire is directly fixed on the pins, the utility model has reliable electrical connection; since the protection housing is arranged at the lower end of the light source for covering the pins and a portion of the wire and for packaging the light source, the pins and the wire as a whole, the utility model has better sealing property and superior waterproof performance compared with the lamp head formed by assembling a split-type bulb and a lamp holder together in the prior art.
Description
Technical field
The utility model relates to a kind of lamp string, the decorative chain that particularly a kind of bulb and lamp socket are structure as a whole.
Background technology
Decorative chain is a kind ofly to connect the ornament lamp that bunchiness is used for decoration occasions by the mode of many bulbs by serial or parallel connection, install with outdoor because decorative chain is general, so the reliability of its water proofing property and electrical connection is very important, generally guarantees the water proofing property of lamp string and the reliability of electrical connection by following connected mode in the prior art.With reference to figure 1, a kind of lamp holder that is used for the lamp holder of lamp string, it generally comprises bulb 01 and 03 liang of big parts of lamp socket, lamp socket 03 squadron one-tenth is equipped with two shell fragments, 04, two shell fragment 04 and is electrically connected with electric wire 05 respectively; Bulb 01 bottom generally also is equipped with a soft core 02, the lamp base of bulb 01 stretches out from soft core 02 bottom, the end that bulb 01 is equipped with soft core 02 inserts in the lamp socket 03, its two lamp base respectively with lamp socket 03 in two shell fragments 04 electrically contact, described soft core 02 upper end operated by rotary motion has anti-limit 021 reaching the waterproof purpose on the port that covers lamp socket 03, and the general and lamp socket 03 of its outer wall closely cooperates to reach and tightens up and secondary waterproof purpose.But, described anti-limit 021 can not stop rainwater fully, again owing to the reason of making, described soft core 02 also can not be very close to each other fully with closely cooperating of lamp socket 03, so still having rainwater in actual use sometimes infiltrates in the lamp socket, cause the short circuit of bulb, after particularly the long-term use of lamp string caused soft core 02 and lamp socket 03 to wear out, this waterproof sealing mode was just more unreliable.Moreover, adopt this this structure the lamp string its be electrically connected also reliably not to the utmost because the elasticity compressing by shell fragment of the lamp base of its bulb 01 electrically contacts, both are non-to tighten up connection, is easy to get loose in the wind and rain of the Nature flickers.In addition, the lamp holder of this structure is made maintenance cost all than higher because parts are various.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of waterproof is provided and is electrically connected reliably the simple integrative-structure lamp string lamp holder of manufacturing maintenance.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of lamp holder that is used for the lamp string, the lead that comprises light source and electrical connection light source, described lead directly is fixed tightly in respectively on two lamp bases of light source, one insulated column that two lamp bases electricity is isolated is set between two lamp bases, described light source lower end form one coat lamp base and part lead and with the into a single integrated structure protective case of described light source, lamp base and lead.
The beneficial effects of the utility model are: owing to lead directly is fixed tightly on the lamp base, so it is electrically connected reliably; Since the light source lower end form one coat lamp base and part lead and with the into a single integrated structure protective case of light source, lamp base and lead, and compare with the lamp holder that lamp socket assembles by the bulb of split in the prior art, its good airproof performance, water resistance is more superior; One insulated column with the isolation of two lamp bases electricity is set between described two lamp bases, like this, in manufacture process, more can prevents from carefully to cause short circuit because of the operation step between the lamp base.
In addition, the utility model can also be further improved by the following technical programs:
One transparent cell-shell is set on the described protective case shrouds described light source, can play the effect of protection light source like this.
Described protective case is provided with an annular groove around described light source, and described cell-shell inserts in this annular groove.
Described lead tightens up by welding and two lamp bases.
Described lead is wrapped in respectively on two lamp bases.

Below in conjunction with drawings and Examples the utility model is described further,
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is one of structural representation of the present utility model;
Fig. 3 is two of a structural representation of the present utility model;
Fig. 4 is three of a structural representation of the present utility model;
Fig. 5 is four of a structural representation of the present utility model;

The specific embodiment
With reference to figure 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of lamp holder that is used for the lamp string, the lead 3 that comprises light source 1 and electrical connection light source 1, described lead 3 directly is fixed tightly in respectively on two lamp bases 11 of light source 1,11 of described two lamp bases are provided with the insulated columns 4 that two lamp bases 11 electricity is isolated, described light source 1 lower end form one coat lamp base 11 and part lead 3 and with the into a single integrated structure protective case 2 of light source 1, lamp base 11 and lead 3.Described light source is power-actuated light-emitting device, can be tengsten lamp, fluorescent lamp or LED lamp, and the light source that the lamp string is used is generally many, and each light source can connect by the mode of serial or parallel connection, and the light source lower end is extended with two lamp bases 11 that connect power positive cathode; Lead 3 is the plain conductor of tape insulation skin commonly used, its can by or the mode of twining directly be fixed tightly on the lamp base 11 double action that the lead 3 in the utility model serves as conduction simultaneously and holds bulb holder; With reference to figure 5 and Fig. 6, described insulated column 4 is " worker " type, comprise backplate 41 be connected two backplates 41 win 42 in succession, insulated column 4 is positioned over 11 of two lamp bases, 41 one-tenth arcuations of two backplates are isolated two lamp bases, 11 electricity, like this, can prevent in manufacture process because machine or workman's maloperation causes 11 short circuits of two lamp bases; After lead 3 tightens up with lamp base 11, can be by casting, injection moulding, the mode that penetrates or extrude form in light source 1 lower end one coat lamp base 11 and lead 3 exposed part and with the into a single integrated structure protective case 2 of light source 1, lamp base 11 and lead 3, the effect of protective case 2 is mainly used in and tightens up being connected of lead 3 and lamp base 11, lamp base 11 when preventing that the lamp string from using out of doors is or/and lead 3 is subjected to the effect of wet short circuit, so its material need have insulating properties and thermoplasticity, and for example plastics, rubber or resin.
As further improvement in the technical proposal; with reference to figure 4; also can on described protective case, an annular groove 21 be set around described light source 1; cell-shell 5 inserts this annular groove 21, like this, just can protect bulb or the not impaired ring of LED lamp as light source 1; certainly; also can a boss 22 be set, again cell-shell 5 be inserted in boss 22 and fix, as shown in Figure 3 around described light source 1.
