Description

Lamp lead structure and lamp

Technical Field

The utility model relates to the technical field of lamps, in particular to a lamp lead structure and a lamp.

Background

Some light fixtures, such as vehicle light fixtures, require leads to be connected to terminals for powering or controlling the light fixtures, etc. The lamp comprises a lamp shell, a lamp body is arranged in the lamp shell, one end of a lead wire enters the lamp shell to be connected with the lamp body, and the other end of the lead wire is connected with a wiring terminal. Some lamps have higher sealing requirements on the lamp housing, and the problem that the lighting effect is affected because water vapor and other gases enter the lamp housing and can be condensed into small water drops in the lamp housing is avoided. However, in the prior art, good sealing is performed at various locations of the lamp envelope, such as at the seam, and at the locations where the leads extend into the lamp envelope. During use, water vapor still enters the lamp housing and condenses into droplets. The problem of entering water vapor in the lamp housing cannot be effectively solved. The inventors have observed over a long period of time that the ingress of water vapor into the lamp envelope is due to the structure of the existing lead wires.

Therefore, how to manufacture a lamp lead structure to avoid the above problems is a technical problem that needs to be solved by those skilled in the art.

It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, based on the examples herein, which are within the scope of the utility model as defined by the claims, will be within the scope of the utility model as defined by the claims.

Hereinafter, embodiments will be described with reference to the drawings. Furthermore, the embodiments shown below do not limit the summary of the utility model described in the claims. The whole contents of the constitution shown in the following examples are not limited to the solution of the utility model described in the claims.

Referring to fig. 1-5, the utility model discloses a lamp lead structure 2, which comprises a plurality of leads 21, wherein the number of the leads can be one, two or more than two. Referring to fig. 2, fig. 2 shows a case of two leads 21. Referring to fig. 3-5, the lead 21 includes a lead sheath 211, and at least two lead bodies 212 are enclosed in the lead sheath 211, four lead bodies 212 being shown. The lead body 212 may be copper wire or the like. Referring to fig. 1 and 2, the lead 21 has at least one length of the lead in a length direction thereof, which is called a first section 22, and a filler 214 is provided in a gap 213 between a lead cover 211 of the first section 22 and a lead body 212.

In some use scenarios, for example, a forklift is used in a more humid environment, and a lamp on the forklift comprises a lamp housing 1, wherein a lamp body is arranged in the lamp housing 1, the lamp body is connected with a lead 21, and the lead penetrates out of the lamp housing 1 and is used for being connected with a power line and the like. The terminals of the lead wires 21 are usually provided with plug connectors 3, and the terminals of the power lines are also provided with plug connectors, so that the connection can be completed through plugging. The inventor discovers after long-term observation that after the two are mutually spliced through the plug connector, gaps exist, and external air (containing water vapor) can enter the plug connector from the gaps. Referring to fig. 3, in the conventional lead wire 21, a gap 213 is generally formed between the lead wire cover 211 and the lead wire body 212, and water vapor enters the inside of the lamp housing 1 along the length direction of the lead wire 21 along the gap 213.

While the present utility model improves upon existing leads by providing at least one segment of the lead to form the first segment 22. Referring to fig. 5, a filler 214 is disposed in the gap between the lead skin 211 and the lead body 212 of the first section 22, and when water vapor flows from the gap to the gap, the water vapor is blocked by the filler 214 and cannot continue to advance into the lamp housing 1.

It should be noted that: the lead 21 may also include a first section 22, may include multiple sections of the first section 22, or may be the first section 22 throughout the entire wire.

Alternatively, referring to fig. 4, the material of the lead skin 211 of the first section 22 may be the same material as that of the filler 214. Of course, referring to fig. 5, the material of the lead skin 211 of the first segment 22 may be a material different from that of the filler 214.

Optionally, the lead sheath 211 and the filler 214 of the first section 22 are formed by wrapping the lead body after heat shrinking by a heat shrink tube.

For example, the original lead skin of the lead can be removed to expose the lead body, and then a heat shrink tube is sleeved on the lead body to perform heat shrink. The heat shrinkage tube is a special polyolefin heat shrinkage sleeve. The outer layer is formed by compounding and processing high-quality soft cross-linked polyolefin materials and inner layer hot melt adhesives, the outer layer material has the characteristics of insulation, corrosion resistance, wear resistance and the like, and the inner layer has the advantages of low melting point, waterproof sealing, high adhesiveness and the like. After the heat shrinkage tube is heat shrunk, the gaps are filled with the hot melt adhesive of the inner layer, and the outer layer is coated on the lead body, so that the structure of the first section 22 is formed.

Optionally, the outer circumference of the plurality of leads 21 is also covered with a protective layer 23.

The protective layer 23 can protect the lead 21 from scratches and the like on the lead cover 211 of the lead 21.

Optionally, one end of the plurality of leads is connected with a plug connector 3.

When the wire is disassembled, the plug can be plugged through the plug connector 3, so that the wire is convenient and simple and is convenient to disassemble.

Optionally, the utility model further provides a lamp, comprising any one of the lamp lead structures 2 described above, wherein one end of the lamp lead structure 2 extends into the lamp housing 1 and is connected with the lamp body.
