Penetrating cable clampTechnical field
The present invention relates to a kind of fastening means of power circuit, particularly a kind of insulation puncture line clamping.
Background technology
Insulated cable is the important component part of electric power system, and in order to realize the fast and safely connection of insulated cable, customary insulation penetrating cable clamp is as Quick connection part.The insulation puncture line clamping of prior art is primarily of insulation upper cover, insulation lower cover, arc seal gasket, piercing blade, cap sleeve and screw rod fastening assembly composition, wherein, screw rod fastening assembly comprises the screw rod running through insulation upper cover and insulation lower cover and the nut being socketed in screw rod one end, nut is provided with the torque nut ruptured afterwards in clamping, the upper cover that insulate during clamping forms two clamp grooves with insulation lower cover, piercing blade is arranged in clamp groove and is wrapped in arc seal gasket, simultaneously when insulating upper cover and the clamping of insulation lower cover, the cap sleeve Connection Block being used for clamping cap sleeve is formed in the both sides of clamp groove.During use, first main line is placed in one in a clamp groove, branch line is placed in another clamp groove, and one end of branch line is inserted in cap sleeve, then with instruments such as spanners, torque nut is tightened, when the piercing blade in clamp groove pierces through the insulating barrier of main line and branch line, torque nut Automatic-falling, now completes the electrical connection of main line and branch line.Owing to adopting insulation puncture line clamping not need the insulated hull peelling off electric wire, therefore the application of insulation puncture line clamping widely.The penetrating cable clamp of this structure once can only complete the electrical connection of two cables, when being electrically connected fast multi-cable simultaneously, then need to use multiple penetrating cable clamp, and the angle of clamp groove is single, cannot realize multi-angle, connect two cables flexibly, it is not very convenient to operate.
Summary of the invention
In view of this, the object of this invention is to provide a kind of penetrating cable clamp, many cables can not only be realized and connect fast, and different angles between cable can be realized, connect fast flexibly.
The present invention is solved the problem by following technological means: a kind of penetrating cable clamp, comprise spherical insulation shell and the vertical rod running through spherical insulation shell, the sleeve be socketed with vertical rod is provided with in described spherical insulation shell, described sleeve one end is fixedly connected with spherical insulation shell, sleeve is provided with the fixing piercing blade that polylith extends to spherical insulation shell, described vertical rod is provided with the activity piercing blade that polylith extends to spherical insulation shell, sleeve is provided with the notch be convenient to activity piercing blade and rotated, described activity piercing blade forms multipair piercing blade group through notch and fixing piercing blade, described spherical insulation shell is provided with multiple through hole be convenient to cable and penetrated, the position one_to_one corresponding of described lead to the hole site and piercing blade group, described vertical rod one end is provided with rotary spacing bar, described spherical insulation shell is provided with rotary spacing groove.
Further, described spherical insulation shell is divided into dismountable upper shell and lower house.
Further, described fixing piercing blade and sleeve removably connect, and described activity piercing blade and vertical rod removably connect.
Further, described through hole is provided with wire sleeve.
Beneficial effect of the present invention:
(1) penetrating cable clamp of this structure, can complete the electrical connection of multi-cable quickly and easily, and structure is simple, easy to process, cheap, connects reliable.
(2) penetrating cable clamp of this structure, can select as required most suitable through hole insert cable carry out puncture connection, achieve arbitrarily angled between cable, connect fast flexibly.
(3) penetrating cable clamp of this structure, can judge that piercing blade group has pierced through the insulating barrier of cable when rotary spacing bar just snaps in rotary spacing groove, without the need to destroying any structure, need than ever to judge more reasonable structure by twisting into two parts torque nut, more save material, decrease production cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the connection diagram of sleeve and vertical rod.
Embodiment
Below with reference to accompanying drawing, the present invention is described in detail, as shown in Figure 1 to Figure 2: this penetrating cable clamp, comprise spherical insulation shell and the vertical rod 2 running through spherical insulation shell, spherical insulation shell is divided into the upper shell 1a and lower house 1b that removably connect, in use procedure, upper shell 1a and lower house 1b links together, the sleeve 3 be socketed with vertical rod 2 is provided with in described spherical insulation shell, described sleeve 3 one end is fixedly connected with spherical insulation shell, sleeve is provided with the fixing piercing blade 4 that polylith extends to spherical insulation shell, described vertical rod 2 is provided with the activity piercing blade 5 that polylith extends to spherical insulation shell, the angle that fixing piercing blade and activity piercing blade extend to spherical insulation shell can be determined as the case may be, described fixing piercing blade 4 removably connects with sleeve 3, described activity piercing blade 5 removably connects with vertical rod 2, sleeve is provided with the notch 3a be convenient to activity piercing blade and rotated, described activity piercing blade 5 forms multipair piercing blade group through notch 3a and fixing piercing blade 4, described spherical insulation shell is provided with multiple through hole 1c be convenient to cable and penetrated, the position one_to_one corresponding of described through hole 1c position and piercing blade group, described vertical rod 2 one end is provided with rotary spacing bar 6, described spherical insulation shell is provided with rotary spacing groove 7.During use, the multi-cable of electrical connection is needed to penetrate from the through hole spherical insulation shell, each through hole penetrates a cable, cable is between fixing piercing blade and activity piercing blade, then vertical rod is rotated, when fixing piercing blade and activity piercing blade pierce through the insulating barrier of cable, rotary spacing bar just snaps in rotary spacing groove, now completes the electrical connection of multi-cable.The penetrating cable clamp of this kind of structure, can complete the electrical connection of multi-cable quickly and easily, and structure is simple, easy to process, cheap, connects reliable.
As the further improvement to technique scheme, described through hole is provided with wire sleeve 8, and wire sleeve can ensure that cable just penetrates through hole, ensures puncture effect.
What finally illustrate is, above embodiment is only in order to illustrate art scheme of the present invention and unrestricted, although with reference to preferred embodiment detailed description to the present invention, those of ordinary skill in the art is to be understood that, can modify to art scheme of the present invention or equivalent replacement, and not departing from aim and the scope of the present invention program, it all should be encompassed in the middle of the present invention's profit claimed range.
