Outside.Insulated cable sheath is connected by connecting tube with insulation booth, and insulated cable sheath is connected through a screw thread with connecting tube.
In the present embodiment, moves collet, clamp head, conductive check lock lever, is conductively connected block and cable connecting terminals by conduction
Material is made, for example, the conductive materials such as copper, aluminium.
The present embodiment uses the specifically used as follows of safe low pressure confluence clamp tool:
First, insulated cable sheath is removed；Then, cable connecting terminals are removed.
Second, the end of low-voltage cable 8 initially passes through insulated cable sheath, covers insulated cable sheath on low-voltage cable；
Then, the core of low-voltage cable end is inserted into cable connecting orifice, and by cable connecting terminals by way of crimping
It is connected as one with the core of cable end, cable connecting terminals are electrically connected with the core of cable end；
Followed by cable connecting terminals are connected through a screw thread by connecting screw with the external screw hole for being conductively connected block.
The connecting tube of third, insulated cable sheath and insulation booth is connected through a screw thread, thus by the line of low-voltage cable end
Core and cable connecting terminals are isolated from the outside, and on the one hand protect the core of low-voltage cable end and the connector of cable connecting terminals；
On the other hand, play the role of being dielectrically separated from, personnel is avoided to get an electric shock.
4th, mouth is crossed into the grafting that the busbar of user terminal passes through insulation booth and is protruded into insulation booth, and makes to protrude into insulation booth
Busbar between clamp head and dynamic collet；
Then, insulation cover plate is removed, is then cooperated using allen wrench and interior hexagonal groove, rotate conductive check lock lever, from
And busbar is clamped with dynamic collet by clamp head；
Followed by insulation cover plate is installed on insulation booth.
The charging member using safe low pressure confluence clamp tool of the present embodiment carries out (insulation booth by insulating part
And insulated cable sheath) isolation, thus its safety in utilization, can effectively avoid confluence clamp, there are people in using galvanization
The problem of security risk of member's electric shock.
Embodiment 2: remaining structure reference embodiment 1 of the present embodiment, the difference is that:
As shown in Figure 2, Figure 3, Figure 4, a kind of using safe low pressure confluence clamp tool, it further include that coordinated type conduction check lock lever stops
Dynamic device 9.
Coordinated type conduction check lock lever stop device includes the limiting slot that several circumferential directions are evenly arranged on conductive check lock lever lateral surface
9.1, the fixed plate 9.2 being arranged in insulation booth and float plate 9.3, setting guide through hole on a mounting board are slidably arranged in
The guide rod 9.5 being connected in guide through hole and with float plate, the limit scotch for being arranged in float plate and cooperating with limiting slot
9.4, it is arranged on insulation booth and the guide sleeve 9.7 parallel with guide rod and the linkage mandril 9.8 being slidably arranged in guide sleeve.
The second end of the close conductive check lock lever of limiting slot, the length direction of limiting slot are equal with the conductive axis of check lock lever
Row.
Fixed plate is parallel with float plate.Float plate is parallel with the conductive axis of check lock lever.Float plate is located at fixed plate
Between conductive check lock lever.Compressed spring 9.6 is arranged on guide rod and between fixed plate and float plate.
The material of linkage mandril is isolation material, such as plastics.The mandril that links is parallel with the axis of insulated cable sheath.
Linkage mandril and float plate are perpendicular.Linkage mandril and fixed plate are located at the opposite sides of float plate.The first end of linkage mandril
In insulation booth, the second end for the mandril that links is located at the outside of insulation booth.
The flange plate for being used to push linkage mandril extended outward is equipped with close to the port of the insulated cable sheath of insulation booth
7.1。
The lateral surface of linkage mandril is equipped with inner limited block 9.9 and outer limited block 9.10.Inner limited block and outer limited block position
In the opposite sides of guide sleeve, inner limited block is located in insulation booth, and outer limited block is located at the outside of insulation booth.
As shown in figure 4, the first end for the mandril that links is against in float plate when outer limited block is against on the end face of guide sleeve,
And separate limit scotch with limiting slot.
Inventor's discovery often occurs insulated cable sheath in the third step of embodiment 1 and is not locked to position, or even occurs
Insulated cable sheath is not mounted to the problem in the connecting tube of insulation booth, so that the core and cable connection end of low-voltage cable end
The connector of son is exposed outside, this is more easily damaged the core of low-voltage cable end and the connector of cable connecting terminals,
Importantly, the present embodiment is improved for this problem there are the security risk of personnel's electric shock, effectively solves this and ask
Topic.
The present embodiment uses the specifically used referring to embodiment 1, difference of safe low pressure confluence clamp tool
It is the third step of embodiment 1:
During insulated cable sheath is tightened in the connecting tube of insulation booth, flange plate will be against the second end of linkage mandril
On, linkage mandril to be pushed up inside, the first end for the mandril that links will be against in float plate, and make float plate close to fixed plate, thus
It is gradually disengaged limit scotch with limiting slot cooperation；When outer limited block is against on the end face of guide sleeve, insulated cable sheath peace
It is attached to position, and limits scotch and is separated with limiting slot.It is implemented in the four steps of example 1 and " utilizes allen wrench and interior six
Groove cooperation in angle rotates conductive check lock lever " this operation can just be gone on smoothly, and busbar is clamped in pincers by conductive chuck
In mouthful；
If insulated cable sheath occur is not locked to position, or even insulated cable sheath occurs and be not mounted in the connecting tube of insulation booth
The problem of when: then limit scotch and limiting slot be still in mated condition, be implemented in the four steps of example 1 " in utilization
Die nut and the conductive check lock lever of interior hexagonal groove cooperation rotation " this operation just will be unable to go on smoothly, i.e. allen wrench
Conductive check lock lever can not be rotated, at this point, operator's insulated cable sheath will be reminded not to be locked to position, it need to be by insulated cable sheath
It is installed in place, it is daily to guarantee being installed in place for insulated cable sheath, it avoids the occurrence of because insulated cable sheath is not locked to position,
Even there is the problem that insulated cable sheath is not mounted in the connecting tube of insulation booth, so that the core and electricity of low-voltage cable end
The connector of cable connection terminal is exposed outside, so that the connector of the core of low-voltage cable end and cable connecting terminals is easy to be broken
It is bad, and there are problems that the security risk of personnel's electric shock.
