Description

[Detailed explanation of the idea] The present invention relates to an opening tool for electric wire connectors.

By the way, in the distribution line construction, for example, the first
As shown in the figure, when connecting branch line B from main line A, a branch connector C is used, and this connector is compressed with a hydraulic compression tool to connect main line A and branch line B. Naturally, when moving the main line, relining the main line, increasing the size of the branch line, etc., it is necessary to remove the compressed branch connector. The current situation is to cut the branch line, or forcefully pull it out by prying it with a ready-to-use tool, which would put strain on the main line.In short, the connector is left on the wire. It is not desirable for the beautification of the city to keep it there.

Therefore, in view of the above problems, this invention proposes a special tool that can easily remove the connector.

First, details of the embodiment will be described with reference to the drawings.

In FIG. 2, reference numeral 1 denotes a tool body, and a press rod 2 having a stopper part 2' at the tip is inserted into the main body 1, and a threaded part 3 is formed in this press rod 2. is screwed into the thread groove 4 of the main body 1, and a fast-forward handle 5 and a ratchet spanner 6 are attached to the push rod 2, and by turning the fast-forward handle 5, the push rod 2 can be screwed in a fast-forward manner. By advancing the lever and turning the wrench 6, a screwing operation for applying pressure, which will be described later, is performed.

On the advancing side of the press rod 2, two acute-angled biting claws 8 are aligned with the central axis of the press rod 2 and are opposed to each other via the insertion space 7 of the connector bar.

The working claws 8 are integrally formed at the sliding ends of a pair of levers 10 whose bases are pivoted to the main body 1 by a shaft 9 so as to be openable and closable.
1, they are biased to close each other.

12 is a grip.

Therefore, in the state shown in Fig. 2, insert the connector with the wire compressed into the insertion space 7, align the joint 2 with the working claw 8, and in this state turn the handle 5 to advance the push rod in rapid forward motion. Press the seam 2 of the connector C against the working claw 8 to temporarily secure it.

Next, rotate the ratchet spanner 6 to tighten the push rod 2.
When moved forward, the joint 2 bites into the working claw 8.
When the wrench 6 is continued to be operated in this biting state to advance the push rod 2, the pushing force is applied to the lever 10 via the connector, and the lever 10 is
As shown in FIG. 3, the connector is opened vertically, thereby forcing the connector to open from the seam.

Therefore, it becomes possible to take out the branch line.

FIG. 4 shows a modified example in which the biting claw 8 is slightly offset from the central axis of the push rod 2, and the pin 12 is inserted into and removed from the pair of levers 10. In this example, the connectors do not overlap easily. If the working claw 8 cannot be inserted into this joint, insert the working claw into the upper and lower parts of the connector that sandwich the joint with the pin 12 set, and then remove the pin 12 and insert it as before. The push rod 2 is advanced to open the connector.

Further, in the previous example, the push rod was moved forward and backward manually, but it is of course possible to provide the tool body with a hydraulic mechanism 13 and move the push rod forward and backward using hydraulic pressure, as shown in FIG. .

As described above, according to the present invention, a connector compressed by an electric wire can be opened with a simple structure and operation, and it has excellent practical effects as a special tool for opening connectors.

Claims (1)

[Scope of utility model registration request] The tool body has a push rod that can be moved forward and backward, and two biting claws that are opposed to each other across the connector insertion space on the advancing side of the push rod. When the push rod advances, it is bitten into the insertion connector between the push rod and the working claw, and is forcibly opened by the pressing force of the connector against the action claw as the push rod continues to advance. A connector opening tool, characterized in that the connector opening tool is provided at each sliding end of a pair of levers whose bases are pivoted to the tool body so as to be openable and closable.
