Description

[Detailed Description of the Invention] This invention relates to a live line connector that connects a branch line to a live main line.

In this type of connector, a bolt is inserted through a hole in the hollow part of the fixed side main body, and the movable main body with the lower part of the bolt screwed and passed through is moved up and down within the hollow part, and when the bolt is tightened, the fixed side main body and opposing electric wire gripping grooves provided on one side of the movable main body approach each other, gripping the main line and the branch line, and tightening and connecting the main line and the branch line. However, since these connections are made while the wires are live, the work must be done using a hot stay.
When performing the above work using a hotstake,
During the above bolt tightening work, the branch wire must be held in the wire gripping groove of either the fixed body or the movable body, and this is extremely complicated work and requires skill. .

This idea was devised in consideration of these points, and by attaching a spacer clamp to the connector that temporarily holds the branch line to be connected, it is possible to connect the branch line extremely easily in the above-mentioned hot stay operation. The purpose is to provide wire connectors.

An embodiment of this invention will be described below with reference to the drawings. First, the connector used in this invention shown in Figs. 1 and 2 will be explained. 1 is a stationary side main body which has a wire gripping groove 1a with an arcuate cross section on the lower surface of a projecting arm provided on one side, and 2 is a main body for this fixed side. This cavity 2 is a hollow portion of the side body 1, and the side and bottom surfaces of the stationary side body 1 facing the wire gripping groove 1a are cut out. Reference numeral 3 denotes a movable main body that is slidably inserted into the cavity 2, and the movable main body 3 has a wire gripping member having an arcuate cross section on the upper surface of a protruding arm provided on one side, facing the wire gripping groove 1a. It has a groove 3a. 4 is a hole that reaches from the upper surface of the fixed side main body 1 into the cavity 2; 5 is a screw that loosely passes through the hole 4 and inserts its lower part into the cavity 2, and passes through the upper and lower sides of the movable side main body 3; The bolt 5 is screwed into the hole 6, and the head 5a of the bolt 5 is located on the upper surface of the fixed main body 1. Reference numeral 7 denotes a bolt retaining ring fitted in the screw groove of the bolt 5 in the hollow portion 2, 8 a locking groove bored in the front and rear surfaces of the fixed body 1, and 9 a wire gripping groove 1 of the fixed body 1.
This is a locking groove provided on the upper outer surface of a. Then the third
To explain the spacer clamp 10 shown in FIG. 4, 11 is a plate made of a conductor with a curved longitudinal section, 12 projects obliquely upward from the center of the upper edge of this plate 11, and has a key piece at the upper end. Claw stick, 1
Reference numeral 3 denotes locking rods projecting downward from both sides of the lower end edge of the plate body 11, and locking pieces 13a facing each other project from the lower end side of each of these locking rods 13. Reference numeral 14 designates two protruding rods that protrude from both side edges of the plate 11 in diagonally rearward and vertical directions of the plate 11, and 15 designates holes drilled in the plate 11. Next, FIGS. 5 to 7 show the state in which the spacer clamp 10 is attached to the connector, and the branch wires 16 to be connected are inserted between the two protrusions 14 on each side of the spacer clamp 10, and the two protrusions 14 are connected to each other. Hold the branch line 16 with the rod 14,
Insert and lock the locking piece 13a of the locking rod 13 into the locking groove 8 bored in the front and rear surfaces of the fixed side main body 1 of the connector, and insert the branch wire 16 into the wire gripping groove 1a to remove the plate. 11 is placed in the wire gripping groove 1a, and the tip end key piece of the claw rod 12 is locked in the locking groove 9 of the stationary side main body 1.

This idea has the above configuration, and it is connected to the main line 17.
To connect the main wire 17 to the main wire 17, the sheath 18 is peeled off to expose the core wire 19, and the core wire 19 is inserted between the wire grip grooves 1a and 3a of the connector which temporarily grips the branch wire 16 as described above. Hook the connector onto the core wire 19 and tighten the bolt 5. Then, the wire gripping groove 3a comes close to the wire gripping groove 1a, and the core wire 19 and the spacer clamp 1 are
0 and the branch line 16 are clamped, and the connection is completed.

As described above, in this invention, since the branch wire 16 is temporarily held in the connector in advance, the connection work is simply hooking the connector onto the core wire 19 and tightening the bolt 5, which makes the work extremely easy.
Therefore, even work using hot stakes can be done without any skill required. Moreover, in this invention, a spacer clamp 10 is used to temporarily hold the branch wire 16 in advance in the connector, but this spacer clamp 10 has an extremely simple structure and can be attached to the conventionally used bicon-type connector extremely easily. It can be locked. That is, the branch wire 16 is inserted between the two protruding rods 14 on both sides of the spacer clamp 10, the protruding rods 14 are bent, and the branch wire 16 is clamped.
The locking piece 13a of the locking rod 13 of No. 0 may be inserted into the locking groove 8 of the connector, and the tip key piece of the claw rod 12 may be inserted into the locking groove 9, respectively. Further, when this spacer clamp 10 grips the core wire 19 of the main wire 17 and clamps it between the wire grip grooves 1a and 3a of the connector, it deforms and conforms to the core wire 19 and the branch wire 16.
The electrical connection between the core wire 19 of the trunk line 17 and the branch line 16 is ensured.

Note that the spacer clamp 1 in the above embodiment
Instead of the pawl rod 12 and the locking rod 13 of 0, a locking rod may be provided protruding from an appropriate outer edge of the plate 11 of the spacer clamp 10, and the tips of these locking rods can be locked. Even if the locking grooves 8 and 9 are provided at appropriate locations on the fixed body 1 of the connector, the same effect as in the above embodiment can be obtained.

As described above, this invention provides a locking groove in the conventional connector, and the spacer clamp that temporarily holds the branch line is pulled into the locking groove to lock the connector, and the connector is removed before connecting to the main line. It is a device that temporarily holds branch wires at the terminal, can use conventional connectors, and is extremely simple by simply preparing a spacer clamp with a simple structure, so it can be manufactured at low cost. This has the effect of facilitating connection work in hotstacking work.
