Technical Field

The utility model relates to an electric wire.

Background

It is known that, in the lighting (especially outdoor lighting) project, a plurality of wall washing lamps or line lamps are installed one by one to connect them into the decorative effect of the light to be shaped. Currently, in order to connect these wall washing lamps or line lamps for power supply, the following two methods are mainly adopted:

one is to cut a gap on the long main electric wire at intervals to connect a lamp group formed by connecting a plurality of wall washing lamps or line lamps in parallel, and then to wrap the gap with an insulating adhesive tape, the working efficiency of the wiring mode is low, and the waterproof effect of the adhesive tape at the gap is weakened after the long main electric wire is used for a period of time;

the other is that a plurality of three-way main wires are connected in series one by one, and then a lamp group formed by connecting a plurality of wall washing lamps or line lamp strings is sleeved on the bypass joint of each main wire.

In addition, in many cases, a plurality of loads need to be connected in parallel on a long main power line in a segmented mode, so that simultaneous or segmented operation of the loads is achieved.

Therefore, the applicant develops a main electric wire which is convenient to connect and lower in use cost.

Disclosure of Invention

An object of the utility model is to overcome prior art's not enough, provide a rational in infrastructure, connect convenient and use cost lower take the main electric wire of a plurality of joints, its waterproof performance is high.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the main wire 1 comprises fire and zero

lines

11, 12 and a main wire sheath 13 which covers the fire and zero

lines

11, 12 in an insulating way;

the connector 2 may be a male or female connector (generally, a male connector, as shown in this embodiment), and includes a connector main body composed of a socket portion 21 and a connection portion 22 at the tail end of the socket portion 21, and a pair of connection terminals 23 provided in the connector main body; the tail ends of a pair of the connecting terminals 23 are piercing heads 231 which are exposed out of the connecting part, and the piercing heads (namely the piercing heads of the pair of the connecting terminals) are respectively inserted vertically from the surface of the main wire sheath 13 and then are respectively connected with the corresponding fire wire and the zero

wire

11 and 12;

the connector fixing seat 3 is an injection molding part which coats and fixes the connecting part 22 of the connector 2 and the corresponding section of the main wire sheath 13.

The utility model discloses when using, use here to use to the brightening engineering as the example: each connector 2 is sleeved with a load connector (the connector and the connector 2 on the main electric wire are a male connector and a female connector) 4 of the wall washing lamp or the line lamp, as shown in fig. 8; when the connection is finished, the live wire and the zero

wire

11 and 12 of the main wire are electrified, and the wall washing lamp or the line lamp can be lightened, so that the effect of lightening a plurality of wall washing lamps or line lamps is achieved. Of course, the utility model can also be used for connecting loads such as other lamps.

In this embodiment, there are 3 connections on the main line, as shown in fig. 1 and 3. In practical application, dozens, hundreds or even more joints can be arranged at certain intervals when the main line is produced according to different use occasions.

From the above, the utility model is characterized in that the piercing head 231 of the exposed end (i.e. the tail end) of the pair of connecting terminals 23 of each connector 2 is vertically inserted from the main wire sheath 13 and connected with the fire and zero

lines

11, 12 in the main wire, and then the connecting part 22 of the tail end of the connector 2 and the corresponding section of the main wire sheath 13 are coated and molded by the injection-molded connector fixing base 3, so as to fix the connector 2 and the main wire 1 together by injection molding and simultaneously realize the electric connection between the connecting terminal 23 in the connector 2 and the fire and zero lines in the main wire sheath 13, in conclusion, the connecting terminal of the connector 3 pierces the sheath of the main wire and then forms the connector fixing base by injection molding, so as to connect the connector and the main wire together and realize the structure of electric wire communication, thus, not only the production efficiency is high, but also a lot of connectors are not needed like a plurality of three-way main wires which are connected one by one in series at the present stage, therefore, the utility model has reasonable structure, convenient connection and lower use cost; additionally, the utility model discloses when connecting many loads (like being used for outdoor brightening engineering wash pinup or line lamp), because the volume of cup jointing of used public, female joint very reduces to help open air waterproof, consequently the utility model discloses a waterproof performance is high.

In this embodiment, as shown in fig. 2 and 4, the connector 2 of the main line is a male connector, and in this case, the load connector 4 of the wall washer lamp or the line lamp is a female connector, as shown in fig. 8, which is more convenient for production. Of course, the connector of the main wire can be a female connector, and the connector of the wall washer lamp or the line lamp can be a male connector.

Preferably, the main wire 1 is a square wire (i.e. the longitudinal section of the main wire is square) to better position the connector and facilitate the smooth connection of the terminal with the fire wire and the neutral wire in the sheath after passing through the sheath of the main wire, which is a flat wire in this embodiment.

In this embodiment, the main wire 1 is provided with two guide grooves 14 corresponding to the fire and

neutral wires

11 and 12 on the surface contacting with the connector 2, so that the piercing head 231 of the terminal 23 can be easily inserted into the sheath of the main wire, and the piercing head can be inserted in alignment with the fire and neutral wires in the main wire, thereby ensuring the electrical connection of each connector during production and use. In this embodiment, a marking wire 15 for distinguishing a fire or a neutral wire is provided in one of the guide grooves 14, which is different in color from the main wire sheath 13, and is formed in the guide groove on the surface of the sheath (e.g., red, yellow) by the way, at the time of production, usually at the time of forming the main wire sheath. Here, the marking line 15 is provided in the guide groove corresponding to the zero line 12, as shown in fig. 2.

Of course, it is also possible to provide the two guide grooves 14 with marking wires of different colors and different colors from the main wire sheath 13. In addition, the color of the marking line can adopt the color of the fire or zero line of the power line which is usually seen by people.

In the present embodiment, the fire and zero

wires

11, 12 are copper wires with different color sheaths (e.g. similar to a single red and blue wire commonly available in the market), as shown in fig. 2 and 5; of course, it may be a pure copper wire (i.e., a copper wire without its own sheath). In addition, the reference numerals of the fire and zero

lines

11, 12 are relative, when one of the lines is selected as the live line to be labeled, the other line is labeled as the zero line, therefore, the reference numerals of the fire and zero

lines

11, 12 can not be used for limiting the utility model discloses.

When the connector is produced, the connecting terminal is placed in a mould to be injection-molded to form a connector main body consisting of the sleeve-joint part 21 and the connecting part 22; alternatively, the connector main body including the socket portion 21 and the connecting portion 22 may be injection molded, and then the terminal may be inserted into the connector main body, as shown in fig. 7 of the present embodiment, in this case, the connector main body is usually provided with a notch 24 to position the terminal.
