Preferably, described body, described upper holder block, described lower lock block are metal material.
Preferably, the sidewall of described lower lock block has some boss, and the inwall of described body has the boss groove matched with described boss.By boss and with the boss groove that boss matches, realizing when wearing main line, lower lock block being fixed on the inwall of body, prevent lower lock block movable image from wearing cable.
Preferably, it also comprises and is at least onely arranged at the inside of described body, the fastener for described branch line and described upper holder block being fixed together.In order to prevent upper holder block arbitrarily movement cause branch line between upper holder block and lower lock block fixing loosely, can fastener be used, make upper holder block compress branch line.
Preferably, the inside of described upper holder block has a counterbore through hole, and the bottom of described fastener is fixed through described counterbore through hole and a screw.
Preferably, described fastener is bolt.By using the bolt that vertically can screw back-out in body, to adjust the Distance geometry tightness degree between upper holder block and branch line.
Preferably, described bolt is torque bolt, and described torque bolt comprises a kingbolt head, a moment of torsion control part, a secondary bolt head.When product is installed, twist kingbolt head, when moment of torsion control part ruptures, upper holder block compresses branch line; When needs dismounting upper holder block, twist secondary bolt head.
Preferably, the inwall of described cavity has the force-bearing piece matched with described bolt, and the inside of described force-bearing piece has the screwed hole matched with described bolt.
Preferably, the both sides of described force-bearing piece have a protuberance respectively, and the inwall of described body has the barb matched with described protuberance.Protuberance and barb cooperatively interact, and can not open because of stressed after making branch's connecting clamp insert branch line, main line, crimping is reliable.
Preferably, bottom described upper holder block, the inwall of described lower lock block top, described bottom groove all has some convex tendons.
Positive progressive effect of the present utility model is: by using the utility model, the electrical connection effect between main line, branch line can be made better, meanwhile, can not cause damage to main line, branch line.

Embodiment
Understood incorporated by reference to Fig. 1, Fig. 5, a kind of branch connecting clamp, it comprises body 2, upper holder block 3, lower lock block 4, is metal material.Wherein, upper holder block 3, lower lock block 4 are arranged at the inwall of body 2, and the bottom of body 2 has one for holding the bottom groove 22 of main line 8, mutually mates to clamp branch line 7 bottom the upper holder block of upper holder block 3 with the lower lock block top of lower lock block 4.In order to better be fixed in bottom groove 22 by main line 8, the bottom of lower lock block 4 has the lower lock block groove matched with main line 8.Bottom upper holder block, lower lock block top all has some convex tendons 31,44.The effect of convex tendon be to make upper holder block 3, lower lock block 4 can better and cable coordinate, increase conductivity, improve mechanical tensile forces characteristic.
Understood incorporated by reference to Fig. 1, Fig. 4, Fig. 6, in order to upper holder block 3, branch line 7, lower lock block 4, main line 8 are better fixed together, a torque bolt 5 for upper holder block 3, branch line 7, lower lock block 4, main line 8 being tightened together can be installed on upper holder block 3.Torque bolt 5 comprises kingbolt head 51, moment of torsion control part 56, secondary bolt head 52, and the bottom of torque bolt 5 has noses 54, and noses 54 inside has screw thread.Noses 54 are fixed together with screw 6 through the counterbore through hole 33 of upper holder block 3.When screw 6 is tightened, be pressed on the inside of noses 54 bottom it, and between upper holder block 3 and screw 6, be matched in clearance, upper holder block 3 can be rotated relative to screw 6, avoid torque bolt 5 and be directly pressed on branch line 7, decrease the damage to branch line 7.
Understood incorporated by reference to Fig. 1-6, the outer wall of torque bolt 5 has screw thread, and the screw thread on the inwall of this screw thread and force-bearing piece 1 matches, and can realize the spinning in and out that torque bolt 5 is vertically gone up in body 2.When product is installed, twist kingbolt head 51, after moment of torsion control part 56 ruptures, main line 8, branch line 7 are all compacted.When disassembly is desired, secondary bolt head 52 is twisted.Pad 9 is arranged between kingbolt head 51 and secondary bolt head 52, and its effect is when screw-down torque bolt 5, avoids kingbolt head 51 to be inserted in secondary bolt head 52.
Understood incorporated by reference to Fig. 1-5, the both sides of force-bearing piece 1 have a protuberance 11 respectively, and the inwall of body 2 has the barb 21 matched with protuberance 11, and the inwall of bottom groove 22 has some convex tendons 23.Barb 21 and protuberance 11 cooperatively interact, and ensure that branch's connecting clamp can not open because of stressed after installing main line, branch line, crimping is reliable.The sidewall of lower lock block 4 has some boss 41, and the inwall of body 2 has the boss groove 24 matched with boss 41.Boss 41 embeds the boss groove 24 of body 2 correspondence, and after the pressure being subject to branch line 7, boss 41 ruptures, and lower lock block 4 moves down and compresses main line 8.The effect of boss 41 is: during installation, because it makes lower lock block 4 position fix, can not teetertotter, and main line 8 is more easily inserted in bottom groove 22.Bottom groove 22 being arranged convex tendon 23 makes it better can coordinate with cable.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
