Abstract
Provided is a clamp for a four-core wire branch line. The clamp for the four-core wire branch line comprises a shell body which is provided with a main line perforating cavity. Four groups of two-way puncture blades are respectively arranged at positions of four space corners of the main line perforating cavity. Press blocks are respectively arranged at the upper end and the lower end of the shell body. An opening of the clamp for the four-core wire branch line is formed by gaps between the press blocks and the corresponding end portions of the two-way puncture blades. A long bolt penetrates through the shell body and the press blocks at two ends of the shell body. A moment nut is connected with the tail end of the long bolt to form a moment type single bolt fastening puncture structure. The clamp for the four-core wire branch line is reasonable in structure, only the long bolt needs to be tightly screwed in installation operation, and the press blocks are pressed inwards. Each two-way puncture blade penetrates through both a main line and a branch line in a conductive mode, no manpower is needed to strip off an insulating layer, convenience is provided, and installation efficiency is greatly improved. Due to control of the moment nut, fastening force is appropriate, and stress of a wire is even.
Description
Technical field: the present invention relates to the branch cable clamp that continuing and branch's gold utensil of a kind of electrical lead, particularly four-core insulated conductor are used.
Background technology: the branch cable clamp that present four-core insulated conductor is used all adopts two bolt fastening structures, and fitting operation is time-consuming, and the fastening pressure that wire is subject to is inhomogeneous.And existing branch cable clamp not have design to the puncture function of branch line, and branch line is fixing conducting main line just after the stripping of insulatin layer manually, and operating process is pretty troublesome, greatly reduces operating efficiency.
Summary of the invention: for the deficiencies in the prior art, the invention provides a kind of fitting operation quad branch cable clamp easily.
The present invention includes the housing that is provided with the main line cavity, be provided with respectively four groups of two-way puncture blades at corner location place, the space of main line cavity, the upper and lower end of housing is provided with briquetting, space between the respective end of briquetting and each two-way puncture blade consists of the branch line jaws, stay bolt runs through the briquetting at housing and two ends, and the end of stay bolt is connected with torque nut, forms torque type list bolted puncture structure.
Of the present invention rational in infrastructure, only need during fitting operation stay bolt is tightened, can will press in briquetting, each two-way puncture blade need not artificial stripping of insulatin layer with the conducting of all puncturing of main line and branch line, and is very convenient, installation effectiveness improves greatly, and by the control of torque nut, fastening strength is appropriate, and wire is stressed evenly.
Further illustrate the present invention below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the perspective view of parallels.
Fig. 4 is the wiring state schematic diagram of Fig. 1.
Fig. 5 is the wiring state schematic perspective view of embodiment.
Embodiment: as shown in Figure 1 to Figure 3, housing 1 is provided with main line cavity 2, be provided with respectively four groups of two-way puncture blades 3 at corner location place, the space of main line cavity 2, the upper and lower end of housing 1 is provided with briquetting 4, and the space between the respective end of briquetting 4 and each two-way puncture blade 3 consists of branch line jaws 5.Stay bolt 6 runs through the briquetting 4 at housing 1 and two ends, and the end of stay bolt 6 is connected with torque nut 7, formation torque type list bolted puncture structure.The present embodiment also is furnished with two movable partitions 8 in main line cavity 2, consist of each heart yearn separating device of main line 10.Also be connected with parallels 9 on each briquetting 4, can prevent briquetting 4 by pressure break, and make the pressure of briquetting 4 more even.In fact, the both sides of parallels 9 also can be provided with two button pin 13, and the respective side walls of button pin 13 and housing 1 moves fastening, and like this in tightening piercing process, housing 1 both sides prevent the stress deformation projection also by 13 fastenings of button pin.
When wiring was installed, as shown in Figure 4 and Figure 5, main line 10 was also that quad passes 2, two movable partitions 8 of main line cavity and each heart yearn of quad can be separated, and make puncture more accurate, and movable partition 8 can adapt to the quad of various cross sectional shapes.When if the specification of main line 10 is thinner, the root of movable partition 8 also movable being connected with compresses adjustment sheet 12, and each heart yearn of quad is correctly separated.Each heart yearn of branch line 11 also needs to be respectively put in corresponding branch line jaws 5, then tighten stay bolt 6, the briquetting 4 at housing 1 two ends is inwardly pressed, and the two ends of each two-way puncture blade 3 can be with the main line 10 of corresponding position and branch line 11 puncture conductings, easy to operate fast.And torque nut 7 can be controlled fastening force, avoids tension excessively loose.
