Referring to shown in Fig. 1,6,7, in this insulation puncture line clamping, opposite cable trough 3 is one group, one group with pressuring line groove 7
For clamping main cables 27, another group is then used to clamp branch cable 26, and typically, branch cable 26 to be connected is than main cables 27
Section is small, therefore two groups of cable troughs 3 can be prefabricated into corresponding size respectively with pressuring line groove 7 according to the model of existing common cable,
To may be selected to use when cable is installed；Since same group of cable trough 3 and pressuring line groove 7 are the same cables of clamping, thus it is aforementioned
Both opposite pressuring line groove 7 and cable troughs 3 in symmetrical structure, be not only symmetrical shape, but also consistent comprising size.
Referring to shown in Fig. 7, in this insulation puncture line clamping, its length, intensity and elastic telescopic portion when wire guide makes
Retractility with the requirement of specific technology, i.e., when main cables 27 and branch cable 26 clamp jail by two groups of pressuring line grooves 7 and cable trough 3
Though when, two puncture tips 10 of one side wire guide can respectively by the insulating layer 23 of main cables 27 and branch cable 26 pierce with
Metallic conductor 24 is steadily contacted, and another aspect elastic telescopic portion is in compression and incomplete compressive state；Making wire guide
When, by being controlled after experiment and calculating material and shape etc., the above-mentioned technology requirement of wire guide is reality of being not difficult
Existing.
Referring to shown in Fig. 3,6,7, the installation method and operation principle of this insulation puncture line clamping are：
When installing and using, the end to be connected of branch cable 26 is closed first with cable sealing cap 25 or insulating tape etc.
Processing, avoids metallic conductor 24 from being contacted with the external world；The single line cable being intended in the main cables 27 and branch cable 26 of connection is put into the right side
In housing 9, wire clamp core assembly from the left end of right shell body 9 is pushed into, is made on the right side of the pressuring line groove 7 of right shell body 9 and wire clamp core assembly
Cable trough 3 is located at the cable both sides；Another cable is positioned in the cable trough 3 on the left of wire clamp core assembly, by 1 clamping of left shell
Outside right shell body 9, and the pressuring line groove 7 of left shell 1 is made to be located at the both sides of the cable with the cable trough 3 on the left of wire clamp core assembly；It borrows
Pressing aid power clamping device drives right shell body 9 and left shell 1 laterally adjacent, due to wire clamp core assembly can online in clip shell component laterally
It is mobile, thus when right shell body 9 and left shell 1 it is close to a certain degree after, main cables 27 and branch cable 26 are respectively by two groups of pressuring line grooves 7
With the clamping of cable trough 3 firmly, balanced；Opposite pressuring line groove 7 and cable trough 3 close to while, every wire guide
Two puncture tips 10 pierce the insulating layer 23 of main cables 27 and branch cable 26 and are connect with the stabilization of metallic conductor 24 in cable respectively
It touches, so as to which main cables 27 and branch cable 26 are connected；Final left shell 1 and right shell body 9 by guiding back-stop mechanism between the two from
Dynamic locking, that is, complete installation.
Referring to shown in Fig. 6,7, when connecting main cables 27 and branch cable 26 using this insulation puncture line clamping, due to main cables 27
It is clamped with branch cable 26 by pressuring line groove 7 and cable trough 3, and pressuring line groove 7 is with being equipped with cushion rubber bumper 6 and fluid sealant in cable trough 3
Pad 2, the chucking power that main cables 27 are subject to branch cable 26 are in admirable proportion, the contact of puncture tip 10 and metallic conductor 24 and close
The leakproofness of potting pad 2 and insulating layer 23 is beneficial to ensure；Due to distribution of lengths of the point of puncture along cable, and it is not limited to line
The surrounding in the same section of cable, thus one, on the one hand, enough wire guides can be set to ensure to puncture in wire clamp core assembly
Tip 10 and the contact area of metallic conductor 24 in cable, to improve current-carrying capacity, on the other hand, in main cables 27 and branch cable 26
Metallic conductor 24 can't reduce effective cross-section because of repeatedly being punctured at same section, i.e. main cables 27 and branch line
The electric conductivity of cable 26 will not be destroyed, in addition, puncturing place along length due to the insulating layer 23 of main cables 27 and branch cable 26
Degree distribution, thus the whole tensile property of insulating layer 23 drop it is very few, and the place of puncturing easily remedied by seal gasket 2 and
Keep good leakproofness；Due to being provided with seal gasket 2 in two cable troughs 3, cushion rubber bumper 6 is provided in two pressuring line grooves 7, and
Wire clamp core assembly has a transverse elasticity telescopicing performance, and thus one, even if main cables 27 and branch cable 26 are sent out by temperature change
It is raw expand with heat and contract with cold deformation when, seal gasket 2 can be closely bonded with main cables 27 and the holding of the puncture side of branch cable 26, and maintenance is good
Good leakproofness, to reach good waterproof, oxidation-protective effect；Since puncture tip 10 and the rigidity of metallic conductor 24 are larger,
When the two is varied with temperature and deformed upon, wire guide can be punctured by the expansion performance that spiral expanding portion 20 has to buffer
Tip 10 and the active force of metallic conductor 24 are in close contact with ensureing that puncture tip 10 is stablized with metallic conductor 24, reduce contact
Resistance improves turn-on effect and anti-seismic performance；As it can be seen that this insulation puncture line clamping has taken into account puncture tip 10 and metallic object with good
There is good leakproofness between electrical contact effect well, seal gasket 2 and insulating layer 23, so as to make this insulating puncturing line
Folder can long-term stable operation, and conductive effect is good.
Furthermore, in this insulation puncture line clamping, outer surface of the wire guide in addition to puncture tip 10 is through exhausted
Edge encapsulation process, it is intended to wire guide be made to have waterproof, the performance of moisture-proof and appearance insulation, thus come the completion stablized by main line
The task that cable 27 is connected with branch cable 26；The insulated enclosure, which is handled, to be realized by adding insulating blanket outside wire guide,
It can be realized in wire guide outer cladding insulating film.
Furthermore, it as shown in Fig. 3,4,5, in this insulation puncture line clamping, is equipped between left pellet 4 and right pellet 5

Right 5 length direction of pellet is spaced apart；Every group of pilot hole 16 is separately positioned on left pellet 4 and right 5 phase of pellet with lead 22
To both ends of the surface on, and make left pellet 4 and right pellet 5 can laterally opposed movement；Thrust spring 21 is set to left pellet 4 and right core
Between block 5, it is intended to it is provided for left pellet 4 and right pellet 5 and both drives separate thrust, therefore thrust spring 21 and laterally steering machine
Structure A can be separately provided, but in order to which the structure of wire clamp core assembly is made to tend to be simplified, and spring can be used integrated with laterally steering mechanism A
Formula designs, i.e., there are two thrust spring 21 is set, is respectively placed in two pilot holes 16, and supported respectively with two leads 22；
Insulation puncture line clamping after installation is complete, thrust spring 21 is in compression and incomplete compressive state, left pellet 4 and right pellet 5
Between still remain buffer gap 8.
Furthermore, being equipped in this insulation puncture line clamping, between right shell body 9 and left shell 1 allows the two laterally adjacent
But the guiding back-stop mechanism that the two is prevented to be distanced laterally from, as its name suggests, being oriented to back-stop mechanism has guiding and the double function of check,
Therefore being oriented to back-stop mechanism can be made up of independently arranged guiding mechanism and back-stop mechanism, existing sliding slot can be used in guiding mechanism
The structure coordinated with slideway, and the pawl structure of two groups of mutual cooperations then can be used to realize in back-stop mechanism, but above-mentioned design
So that being oriented to, back-stop mechanism is whole not enough to be simplified, for this purpose, following design can be used in this guiding back-stop mechanism：
I.e. as shown in Figure 2,3, 4, it is oriented to back-stop mechanism and includes four guiding tooth sockets 15 for being mutually parallel and being laterally extended, it is right
The both side plate outer wall of housing 9 is respectively provided with two be spaced apart, is oriented in tooth socket 15 and is equipped with check tooth 13；And left shell 1 is each
The two groups of teeth tooth 14 being spaced apart is equipped on the inner wall of side plate；Left shell 1 is held in outside right shell body 9 and four groups of teeth 14 are fallen into
During four guiding tooth sockets 15, left shell 1 keeps opposite and parallel with the pressuring line groove 7 of right shell body 9, i.e., four groups of teeth 14 are led with four
Coordinate to tooth socket 15 and realize guiding；Four groups of teeth 14 and four cooperations of check tooth 13 being oriented in tooth socket 15 can prevent left shell 1
It is distanced laterally from right shell body 9, that is, realizes locking.
Furthermore, referring to shown in Fig. 2,3,4,5, in this insulation puncture line clamping, wire clamp core assembly is placed in left housing
In the cavity that body 1 and right shell body 9 are formed after assembling and can in the cavity transverse shifting, online sandwich component and right shell can be passed through
Laterally steering mechanism B is set to realize between body 9, i.e. the upper surface of wire clamp core assembly with lower face is each provided with two transverse directions and prolongs
Guide chute 12 stretching, being spaced apart, and the inner wall of 9 both side plate of right shell body is respectively provided with two and is slidably matched with guide chute 12
Guiding rib 11, four guiding ribs 11 and the cooperation of four guide chutes 12 make wire clamp core assembly can be in 9 groups of left shell 1 and right shell body
Transverse shifting in the cavity formed after dress；Thus one, it can be ensured that the central shaft of two cable troughs 3 and two pressuring line grooves 7 four is always
It is parallel and coplanar, and when left shell 1 and right shell body 9 close to when, wire clamp core assembly can by transverse shifting, ensure main cables 27 with
The chucking power that branch cable 26 is subject to is suitable.
Furthermore, in this insulation puncture line clamping, since buffer gap 8 passes through with cable trough 3 in wire clamp core assembly
Thread eye 18 connects, there is also gap between the straight line portion 19 of wire guide and thread eye 18, after installation is complete, although sealing
Rubber cushion 2 can will be isolated, but this isolating seal is difficult to maintenance steady in a long-term at the puncture of insulating layer 23 with thread eye 18,
Outside moisture, oxygen be easy to by gap between wire guide and thread eye 18 enter at puncture and to puncture tip 10 with
The contact site of metallic conductor 24 is aoxidized, is corroded, and influences turn-on effect, in order to avoid the generation of the above situation, the present invention
Also there is following improve：
I.e. as shown in figure 8, thread eye 18 is respectively being installed on a seal rubber sleeve 28 at the position of 17 both sides of filament guiding seat, gold
The straight line portion 19 for belonging to 20 both sides of seal wire spiral expanding portion is passed through from corresponding seal rubber sleeve 28, straight line portion 19 and seal rubber sleeve 28
Cooperation is slidingly sealed, so as to which seal rubber sleeve 28 will carry out secondary isolation at puncture with thread eye 18, to ensure the sealing at puncture
Property；Seal rubber sleeve can be fixed in thread eye 18 by adhesive, and can also be reserved in thread eye 18 can dispose seal rubber sleeve 28
Hole seat.
Furthermore, as shown in figure 5, in above-mentioned insulation puncture line clamping, exist between left pellet 4 and right pellet 5
Buffer gap 8, and wire guide certainly will need to be passed through from buffer gap 8, buffer gap 8 such as without encapsulation process and with the external world
Directly communicate, certainly will be there are larger security risk, therefore the present invention also has following improve：
I.e. as shown in figure 9, the both ends of the surface outer rim opposite with right pellet 5 of left pellet 4 is respectively provided with a socket step 29, a square tube
30 both ends of telescoping tube of shape are nested with respectively on two socket steps 29, thus by the buffer gap between left pellet 4 and right pellet 5
8 are closed, the outer wall of telescoping tube 30 cause not higher than the lateral wall of wire clamp core assembly telescoping tube 30 not with wire clamp shell component
Contact；Thus one, buffer gap 8 is isolated from the outside by telescoping tube 30, and moisture, air is avoided to enter inside wire clamp core assembly,
Improve the stability of insulation puncture line clamping.
Furthermore, referring to shown in Fig. 1,6,7, when this insulation puncture line clamping is installed, left shell 1 and right shell body need to be driven
9 is close, can make wire clamp shell component that main cables 27 be clamped and be connected with branch cable 26 with wire clamp core assembly, but left shell 1 with
On the one hand right shell body 9 is such as too close to can make wire clamp core assembly be fully compressed and lose pooling feature, on the other hand also have
The chucking power that main cables 27 are subject to the folder of branch cable 26 may be caused excessive and generate serious permanent deformation or damaged；Therefore left shell
1 is appropriate close to being clamped to main cables 27 after which kind of degree and branch cable 26 with right shell body 9, needs to slap with experience with observation
It holds, certain difficulty certainly will be increased to the installation operation of this insulation puncture line clamping, therefore the present invention also has following improve：
I.e. as shown in figure 11, be respectively provided on the both side plate outer wall of right shell body 9 it is one extending along its length, outwardly protrude
Positioning bar 32, when the both side plate end of left shell 1 is supported respectively with two positioning bars 32, wire clamp core assembly and wire clamp shell component will
Main cables 27 clamp just with branch cable 26；Position of the positioning bar 32 on the both side plate of right shell body 9 is computed early period making
And many experiments are not difficult to determine.
Furthermore, referring to shown in Fig. 7,8, in above-mentioned insulation puncture line clamping, wire guide is by puncture tip
10 main cables 27 and the metallic conductor 24 in branch cable 26 are connected, therefore puncture tip 10 and the contact area of metallic conductor 24 are straight
Connecing influences the current-carrying capacity of contact position, if puncture tip 10 uses traditional needle point formula structure, then puncture tip 10 and metallic conductor
24 be point contact, is unfavorable for ensureing puncture tip 10 and the current-carrying capacity of 24 contact position of metallic conductor, can only be by increasing puncture tip
10 quantity is held to overcome, on the one hand can increase the manufacture difficulty of insulation puncture line clamping, on the other hand then lead to insulating layer 23
Puncture place it is more, leakproofness is more difficult to ensure that；To overcome above-mentioned deficiency, the present invention also has following improve：
I.e. as shown in Figure 10, the top of puncture tip 10 is "-" type blade 31, and the blade tip of the "-" type blade 31 is in straight
Threadiness, and the straight line where blade tip and the centerline axis parallel of cable trough 3；Thus one, puncture tip 10 and metallic conductor 24
Non- point contact, but contacted in line, increase puncture tip 10 and the contact area of metallic conductor 24, improve the current-carrying of contact position
Amount.
Referring to shown in Fig. 1,8, in this insulation puncture line clamping, wire clamp core assembly is with wire clamp shell component respectively by two cables
3 and two pressuring line groove 7 of slot implements clamping to main cables 27 and branch cable 26, in order to ensure cable trough 3 and pressuring line groove 7 and to main cables
27 and the clamping effect of branch cable 26 more stablize, the section of the pressuring line groove 7 and cable trough 3 is in minor arc shape；While by
The both sides that focus primarily upon cable in the chucking power that pressuring line groove 7 and cable trough 3 provide main cables 27 and branch cable 26 opposite, therefore
Can main cables 27 and branch cable 26 be provided with pressure and the guarantee of stable equilibrium in order to ensure seal gasket 2 with cushion rubber bumper 6
Seal gasket 2 can be to playing good sealing effect at cable puncture, the seal gasket 2 and the section of cushion rubber bumper 6 are equal
