Description
Technical Field
The utility model relates to a cable pencil field, more specifically relate to a pencil connection structure who is particularly useful for in boats and ships.
Background
In vehicles such as automobiles, ships, and airplanes, a large number of wire harnesses are connected between a power supply and various electric devices to transmit electric power. Since each electric device is provided at a plurality of different positions, a plurality of branches need to be led out from the main power supply line and connected to the different electric devices, respectively.
Referring to fig. 1, there is shown a schematic diagram of a wire harness connection structure currently used in a ship, the ship wire harness connection structure including a main wire 1 ', a plurality of branch wires 4', a connector 2 ', and a plurality of power receiving devices (such as electric devices or other connectors connected to the electric devices) 3'. The main line 1 'may be a power line or a ground line, that is, a first end of the main line 1' is directly or indirectly electrically connected to a power source (not shown) or grounded, and a second end of the main line 1 'is connected to a power supply terminal or a ground terminal of the connector 2'. The power supply terminals or the ground terminals of the other power receiving devices 3 ' are connected to the main line 1 ' through branch lines 4 ', respectively.
The branch line 4 ' has a first end electrically connected to the connection terminal of the corresponding power receiving device 3 ', and a second end electrically connected to the main line 1 '. When electrically connecting the second end of each branch line 4 'to the main line 1', it is necessary to first cut the outer insulation sheath of the main line 1 'at the electrical connection portion 10' (located at the middle position of the main line 1 'rather than the end position) of the two to expose the metal core material thereof, then join the metal core material of the end portion of the branch line 4' and the metal core material of the main line 1 ', and then wrap the connection portion 10' of the two with an insulating material again. Because the working environment of the ship is severe, the wire body of the wire harness may need to pass through the poor working environment, and in order to enable the connection part 10 'of the main wire 1' and the branch wire 4 'in the severe environment to meet the strict requirements of water resistance, oil resistance, corrosion resistance and the like, a multilayer protection measure is usually additionally arranged at the connection part 10' of the main wire 1 'and the branch wire 4'. For example, after the connection portion 10 ' of the main wire 1 ' and the branch wire 4 ' is wrapped with an insulating material, a partial length of the branch wire 4 ' is bundled with the main wire 1 ', a plastic tape is wound around the portion where the branch wire 4 ' is bundled with the main wire 1 ', a sheath is sleeved outside the plastic tape, and finally the sheath is fastened with a binding tape.
In this wire harness connection structure, the main wire 1 'needs to be cut open many times to enable the plurality of branch wires 4' to be electrically connected with the main wire 1 ', and in addition, the connection portion 10' of each branch wire 4 'and the main wire 1' needs to use a plurality of layers of protective materials and to perform a plurality of times of protective operations, which results in that the wire harness connection operation is extremely time-consuming and labor-consuming, and the cost of the wire harness connection structure is high. Furthermore, even if the connection portion 10 'of the branch line 4' and the main line 1 'is protected by a multi-layer protection measure, the water-proof, oil-proof and corrosion-proof effects of the connection portion 10' are still not desirable.
The present invention is directed to solving one or more of the problems set forth above in the prior art.

Detailed Description
Referring to fig. 2, a wire harness connection structure according to an embodiment of the present invention is shown. As shown in the drawing, the wire harness connection structure includes: a first connecting line 1, a first connector 2 and a plurality of second connecting lines 4. The first end of the first connection line 1 is adapted to be directly or indirectly electrically connected to a power source (not shown) or grounded, and the second end 211 of the first connection line 1 is electrically connected to the first connector 2, for example, connectable to a connection terminal (a power terminal or a ground terminal corresponding to the purpose of the first connection line 1) of the first connector 2. As can be seen, the first connection wire 1 corresponds to the main wire 1' in the conventional wire harness connection structure shown in fig. 1, and is a wire for directly or indirectly transmitting power from a power source to the first connector 2 or directly or indirectly leading from the first connector 2 to a ground point.
A first end of each second connection line 4 is electrically connected to a corresponding one of the powered devices. The powered device may be, for example, the illustrated powered device 3 or the second connector 6. The second end of each second connection line 4 is electrically connected to the first connection line 1 near the second end 211 of the first connection line 1 to form a corresponding first electrical connection portion. Specifically, the metal core material (which is relatively easily exposed after peeling off the outer insulating cover) at the second end of each second connection line 4 and the metal core material (which is originally exposed because of the electrical connection with the connection terminal of the first connector 2) at the position near the second end of the first connection line 1 are joined to each other by crimping, welding, winding connection, or the like, thereby forming corresponding first electrical connection portions. It will be readily understood that the first electrical connections may be separate from one another (in the case shown in figure 2) or coincident, but they are both located close to the first connector 2.
It should be noted that, in the present invention, the "second end of the first connecting wire 1 is electrically connected to the first connector 2" should be broadly understood from the point of electrical connection, i.e. it includes not only the case where the first connection line 1 itself extends physically all the way to the connection terminals of the first connector 2 and is directly connected with the connection terminals of the first connector 2 through the second end 211 of the first connection line 1 itself (i.e. the case shown in figure 2), but also "the second end 211 of the first connection line 1 itself does not physically extend to the connection terminal of the first connector 2, but by first being connected to another physical wire and then connected to the connection terminal of the first connector 2 via the other physical wire, in this case, the other physical wire should be regarded as a part of the first connection wire 1 from the viewpoint of electrical connection. The other physical line may be a separate line other than the first connection line 1 and the second connection line 4, or may even be a segment of the second connection line 4 directly connected to the connection terminal of the first connector 2 (in this case, physically, the second end of the second connection line 4 is directly connected to the connection terminal of the first connector 2, and the second end of the first connection line 1 is connected to the second connection line 4 near the second end of the second connection line 4).
Referring now to fig. 3 and 4, an example of the first connector 2 is shown, the first connector 2 including a first connector body 21 and a first protection cap 22. The first side surface 210 of the first connector main body 21 is provided with a first mating portion (not shown) that can be mated with a not-shown electrical device, and the first protective cover 22 is attached to the second side surface of the first connector main body 21, that is, the side of the first connector 2 electrically connected to the first connection line 1. In this embodiment, the second side is the opposite side to the first side (i.e., parallel), and in other embodiments, the second side is, for example, a side that is at an angle or even perpendicular to the first side. For example, the first protector 22 is substantially tapered, and has a flared end fitted to the first connector body 21 and a hole opened at the flared end for passing each wire, the diameter of the hole being variable depending on the number and thickness of the wires passing therethrough.
Since the first electrical connection portions formed between the first connection lines 1 and the respective second connection lines 4 are located close to the first connector 2, the first electrical connection portions can be disposed inside the first protection cap 22. Specifically, the first protective cover 22 may enclose a first chamber with the first connector body 21. The metal core material near the second end of the first connection line 1 and the metal core material at the second end of each second connection line 4 are electrically connected in the first cavity, and the first protection cap 22 protects the first electrical connection portion therebetween.
Preferably, the first electrical connection is surrounded by a first protective layer 5 within a first protective cover 22 to provide a more direct primary protection to the exposed metal core. The first protective layer 5 may be formed, for example, by a multilayer wound insulating tape.
In the illustrated embodiment, the total number of the second connection lines 4 electrically connected to the same first connection line 1 is two, but is not limited thereto. Obviously, the number may be one or more than two.
It should be noted that, for convenience of description of the technical solution of the present invention, the embodiment shown in fig. 3 and 4 only shows a schematic view of the first connection line 1 and the second connection line 4 electrically connected to the first connector 2. It is understood that the wires connected with the first connector 2 are not limited to the first and second connection lines 1 and 4 for transmitting power or grounding, but may also include a plurality of other wires for data or signal transmission, for example. Accordingly, the first connector 2 may also include a connection terminal for connecting a data line or a signal line. The specific manner of electrically connecting the respective ends of the other wires with the corresponding terminals of the first connector 2 can be referred to in the prior art, and is not described herein.
The first end of the second connection line 4 may be directly connected to the electric equipment 3 as the power receiving device. Alternatively, the first end of the at least one second connection line 4 may also be connected to the second connector 6 as a power receiving device, as necessary. In this case, the wire harness connection structure in the illustrated embodiment further includes the second connector 6 and one third connection wire 8. Similarly to the second connection line 4 led out from the first connector 2, the first end of the third connection line 8 is also electrically connected to a corresponding powered device (e.g., the electrical equipment 3 in fig. 2), and the second end of the third connection line 8 is electrically connected to the second connection line 4 of the second connector 6 near the first end of the second connection line 4 to form a second electrical connection portion. That is, the metal core material (which is relatively easily exposed after peeling the outer insulating cover) at the second end of the third connection wire 8 and the metal core material (which is originally exposed because of the electrical connection with the terminal of the second connector 6) at the position near the first end of the second connection wire 4 are joined to each other by crimping, welding, winding connection, or the like, thereby forming the second electrical connection portion. It will be readily appreciated that the second electrical connection will be located close to the second connector 6.
As an example, the structure of the second connector 6 is substantially the same as that of the first connector 2 described above. Specifically, the second connector 6 may include a second connector body and a second boot. The first side of the second connector body is provided with a second plug-in part which can be plugged into an electrical consumer, and the second protective cover is mounted on the second side of the second connector body, i.e. on the side of the second connector 6 which is electrically connected to the corresponding second connecting wire 4. The second protective cover may have the same configuration as the first protective cover 22 described above.
Since the second electrical connection portion formed between the third connection line 8 and the second connection line 4 is located close to the second connector 6, the second electrical connection portion can be provided inside the second protective cover. In particular, the second boot may enclose a second chamber with the second connector body. The metal core material near the first end of the second connection line 4 and the metal core material at the second end of the third connection line 8 are electrically connected in the second cavity, and the second protective cover shields the second electrical connection portion therebetween.
Incidentally, the connection relationship between the second connector 6 and its associated second connection line 4 and third connection line 8 is practically identical to the connection relationship between the first connector 2 and its associated first connection line 1 and second connection line 4, i.e. the definition of the connection relationship between the first connector 2 and its associated first connection line 1 and second connection line 4 in the present invention is also satisfied.
Also preferably, the second electrical connection may be surrounded by a second protective layer within a second protective covering to provide a more direct primary protection to the exposed metal core. The second protective layer can likewise be formed, for example, from a multilayer wound insulating tape.
In the embodiment shown in fig. 2, the total number of the third connection lines 8 electrically connected to the same second connection line 4 is one, but is not limited thereto. Obviously, the number may be two or more.
In addition, the wire connected to the second connector 6 is also not limited to the second connection line 4 and the third connection line 8 for transmitting power or grounding, but may also include a plurality of other wires for data or signal transmission, for example. Correspondingly, the second connector 6 may also comprise connection terminals for connecting data lines or signal lines.
In the illustrated embodiment, the first connection line 1 is one and the first connector 2 is one, but in other embodiments, the number of the first connection lines 1 electrically connected to the same first connector 2 may be two or more, and the number of the first connectors 2 may be two or more. In addition, in some embodiments, the number of second connectors 6 and third connection lines 8 may also be greater than in the illustrated embodiment. Furthermore, the first end of the third connecting line 8 in fig. 2 may not be connected to the consumer 3 but may be connected to another connector identical to the first and second connectors, and one or more fourth connecting lines may be branched from the vicinity of the first end of the third connecting line 8 and further similarly branched one by one, and finally a harness connecting structure having a plurality of levels of connectors and corresponding connecting lines may be obtained.
It is to be understood that the harness connection structure connected to the power supply may be the harness connection structure of the above-described embodiment, and the harness connection structure connected to the ground may also be the harness connection structure of the above-described embodiment.
In the present invention, the terms such as "first", "second", "third" and "fourth" are only used to distinguish the relevant connecting lines or connectors, and do not limit the number or order of the connecting lines or connectors.
