Specifically, constituting the anti-watertight of the first sealant layer 3 to allow the first sealant layer 3 to play good leakproofness
Conducting wire 12 in sealing and the first protective layer 11 and cable main body 1 should all have good adhesive property, to allow first close
Adhesive layer 3 and the first protective layer 11 and conducting wire 12 be respectively formed it is good contact, avoid because of the first sealant layer 3 and cable main body 1
Other parts adhesive properties it is insufficient and have an impact gap and the hole of 1 air-tightness of cable main body and waterproofness.
At this time, it may be necessary to illustrate, certain insulation and waterproof performance can have between each conducting wire 12 in connecting line,
Even if thus extraneous Trace Water Vapor is penetrated into inside connecting line, shadow will not be caused to electric signal transmission normal in connecting line
It rings.
Specifically, in cable main body 1, the conducting wire 12 being wrapped in the first protective layer 11, either being directly used in biography
The core of power transmission signal is also possible to the external individual core for being enclosed with isolation protective material.It is specific individually below to carry out in detail
Explanation.
In a kind of optional mode, each conducting wire 12 being wrapped in the first protective layer 11 can be directly used for transmission
The core of electric signal., can also be by more material winds at harness shape at this point, core can be one, and each core can be with
Independence is wound in the harness being relatively large in diameter, to complete different signal transfer functions.
Fig. 4 is the structural schematic diagram of another cable main body in the connecting line of the offer of the utility model embodiment one.Fig. 5 is
The schematic cross-section of cable main body in Fig. 4.As shown in Figure 4 and Figure 5, in another optional mode, in cable main body 1
Conducting wire 12 can specifically include core 121 and be wrapped in second protective layer 122 in 121 outside of core, the second protective layer 122 and core
The second sealant layer 4 is filled in gap between body 121.
Specifically, each wire 12 in cable main body 1 all can be independent core 121, thus when in cable main body 1
Included multiple conducting wires 12 may be respectively used for transmitting different signals, to complete more complicated signal transfer functions.For
It avoids interfering with each other between the signal on different conductor 12,121 outside of core of each wire 12 is enclosed with second
Protective layer 122 is similar with the first protective layer 11, and the second protective layer 122 is also made of insulating materials, and can completely cut off outside water
Vapour, thus insulation protection can be played between core 121 and the external world, core 121 and extraneous conducting are avoided, and believe
Phenomena such as number interference is even short-circuit.Each wire 12 can be used to transmission and the different electric signal of other conducting wires 12 in this way.Tool
Body, the first protective layer 11 and the second protective layer 122 can by polyvinyl chloride (Polyvinyl chloride, PVC) or its
The materials such as its common ambroin are made.
Since each wire 12 includes core 121 and the second protective layer 122 for being wrapped in the outside of core 121, thus
It is similar with the first protective layer 11, can also have certain gap between the second protective layer 122 and core 121, and these gaps
Also will form can hold the channel that steam passes through.If extraneous steam enters cable main body 1 from the connector 2 of connecting line, may
Advance always along the gap between the second protective layer 122 and core 121, and is entered in device by the inscribed end of cable main body 1
Portion.
Thus, in order to avoid steam impacts the element manipulation inside device, in the second protective layer 122 and core
The second sealant layer 4 can be equipped between 121, the second sealant layer 4 is filled between the second protective layer 122 and core 121
In gap, thus the gap can be filled up, and the gap is closed.At this point, if there is steam enters the second protective layer 122
In gap between core 121, and when the location of second sealant layer of arrival 4, it can be hindered by the second sealant layer 4
It keeps off and can not move on, such steam also cannot propagate into the inside of device, play the role of waterproof sealing.
In this way when conducting wire 12 is to include the separate conductors 12 of core 121 and the second protective layer 122, by core
121 and the second gap between protective layer 122 in fill the second sealant layer 4, the gap inside conducting wire 12 can be closed, into one
Step improves connecting line for the exclusion seal effect of extraneous steam.
Wherein similar with the first sealant layer 3, the second sealant layer 4 also can be set at the inscribed end of cable main body 1,
So that the inscribed end of cable main body 1 forms closed end, the entrance of steam is hindered.In this way by the first sealant layer 3 and the second sealing
Glue-line 4 is arranged at the end position of cable main body 1, can convenient for the filling of the first sealant layer 3 and the second sealant layer 4
To reduce the manufacture difficulty of connecting line, and be conducive to improve the sealed waterproof effect of sealant layer.
Likewise, similar with the first sealant layer 3, the second sealant layer 4 can also be using bonding agents such as waterproof gasket cements
It is made.It can will be specifically poured between core 121 and the second protective layer 122 in the waterproof gasket cement before condensation in flowable state,
And using the mobility of waterproof gasket cement, it is made to fill these full gaps, after bonding agent condensation, so that it may by 121 He of core
Gap between second protective layer 122, which is closed, completes.
In order to guarantee the transmission quality of signal, as a kind of optional structure, in the cable main body 1 of connecting line, every
It may include more cores 121 in conducting wire 12.More cores 121 can be with common transport signal, to lower connecting line in this way
Impedance, improves the transmission quality and signal strength of signal, and avoids single core 121 from being broken and the feelings that cause signal that can not transmit
Condition occurs.
Specifically, each core 121 in each wire 12 all can be single wire rod.In general, core 121 can be
Metal wire rod is constituted, such as can be the core 121 that conducting wire 12 is constituted using copper wire, at this point, core 121 in conducting wire 12 can be with
For copper stranded conductor.
It, equally can there are one between different cores 121 however, when in each wire 12 including more cores 121
Fixed gap.When intaking in this way at the connector of connecting line 2, extraneous steam may enter each core in solid conductor 12
In gap between 121, and channel is formed by across whole connecting line along these gaps, eventually enter into inside device.For
It avoids the extraneous steam from entering inside device via the gap between core 121 each in solid conductor 12, needs to solid conductor
It is sealed processing between 12 each core 121, to eliminate the gap between each core 121.
Fig. 6 is the structural schematic diagram of the third cable main body in the connecting line of the offer of the utility model embodiment one.Such as Fig. 1
With shown in Fig. 6, as an alternative embodiment, by that can lead between the more cores 121 that can be allowed in each wire 12
The fusant sealing of electricity.At this point, fusant can protrude into the gap between each core 121 in the molten state, and with 121 table of core
Face forms good contact, and the gap between core 121 each in this way can be melted object and be filled up, to allow fusant and core
Body 121 links together jointly, and constitutes the closed end that can seal waterproof.
Wherein, fusant is that conductive material is formed, thus fusant itself does not interfere with normally leading for core 121
Electrical property, to can guarantee the good transmission of signal.In general, fusant can be lower melting-point metal, can lead in this way
Cross and allow metal in flowable state into heating, metal flows into the gap between each core 121 of conducting wire 12, and fill up these gaps it
Afterwards, then metal cooled and solidified is allowed, metal can link together each core 121, to allow in conducting wire 12 each core 121 in gold
The position for belonging to melting constitutes unified entirety, so that the position for avoiding extraneous steam from condensing from metal melting passes through.
Specifically, plating can be passed through between more cores 121 in each wire 12 as one of optional mode
Tin sealing.Wherein, tin has lower fusing point and good electric conductivity, thus allow between each core 121 by it is tin plating even
It connects and is sealed, can preferably fill and eliminate the gap between each core 121, complete close inside conducting wire 12
Envelope.
Further, as long as due to allowing the end of conducting wire 12 to be sealed, it can allow conducting wire 12 that there is good air-tightness
And sealing performance, thus when each core 121 carries out tin plating in conducting wire 12, the tin plating position of core 121 can be core
The end of body 121.At this point, being coated with one layer of tin layers 123 in each wire 12 on the end of each core 121 jointly.In this way in core
The end of body 121 carries out tin plating operation, allows the end of each core 121 in conducting wire 12 to plate tin layers 123, the end of core 121 is just
Sealing can be completed under tin plating effect.
At this point, in order to allow the tin of molten state to fill the gap between core 121, it can be by the of conducting wire 12 each in connecting line
Two protective layers, 122 end peels off, and the end portion of core 121 is exposed outside, at this point, outside eliminates the second protective layer
122 121 end of core can conveniently complete tin plating operation.It is convenient for operating when tin plating in this way, can reduce
The manufacture difficulty of connecting line reduces production cost.
Wherein, when sealing in completing conducting wire 12 in the way of tin plating between more cores 121, in order to guarantee to seal
Performance, optionally, the tin plating length of 121 end of core can be 4-6mm, and generally in 5mm or so.At this point, on core 121
Tin plating length is relatively mild, on the one hand can guarantee in the tin plating gap that can be filled between each core 121, good to realize
Sealing performance；On the other hand, tin plating length convenient for completing the operation of tin plating process, and is reduced tin plating between 4-6mm
Amount, effectively reduces the production cost of connecting line.
And likewise, when completing the waterproof sealing of connecting line using the first sealant layer 3 and the second sealant layer 4,
