technical field

The utility model relates to auxiliary equipment of a power distribution station, in particular to an automatic switch live debugging adapter.

Background technique

When testing the communication protocol configuration, standard point meter, etc. of the automatic switch, since the stock switches are all in the live running state, if the power failure debugging will greatly affect the reliability of the power supply. Therefore, the method of live debugging is generally used to test whether the functions of the automatic switch are normal.

At present, the existing automatic switch adjustment adapter needs to unscrew the screw to connect to the socket of the tester and then insert the wiring of the tester, which is inconvenient and time-consuming to operate. At the same time, in order to tighten the wiring, after inserting the tester wiring, in order to avoid loosening the wiring during the debugging process and protect the staff, it is necessary to tighten the screws. It is difficult to grasp the tightness of the tightening screws, and it is easy to cause damage to the terminal of the tester wiring. lead to deformation.

In order to solve the above-mentioned technical problems, the technical scheme adopted by the present utility model is: an automatic switch live debugging adapter, including a junction box, one side of the junction box is provided with a wiring hole for accessing the switch wire joint, and the wiring hole is provided. The opposite side is provided with a wire socket corresponding to the wiring hole, the wire socket is equipped with a wire gripper for fixing the wiring head, and the wire gripper includes a wire plug hole and an inlet installed in the wire plug hole. A movable pressure block that shields the inlet and a metal sheet installed in the wire insertion hole, the movable pressure block is installed on the wire clamp through a reset elastic member, and the metal sheet is connected to the wiring hole through a wire.

The wire connector of the automatic switch is connected to the wiring hole, and the movable pressure block is moved by external force to expose the plug-in hole. Insert the terminal of the tester into the plug-in hole, release the movable pressure block, and reset the elastic piece to reset the movable pressure block. The pressure block clamps and fixes the wiring head in the plug-in hole, and the wiring head of the tester forms a debugging circuit by contacting the metal sheet and the automatic switch.

Preferably, the reset elastic member is a torsion spring, which is installed on the front side of the inlet side of the wire gripper, and the movable pressing block is L-shaped. The user only needs to press one side of the movable pressure block, and the side of the movable pressure block blocking the entry port swings upward to expose the plug hole, which is easy to operate and can easily achieve the effect of long-time pressing to expose the plug port.

As another preferred solution, the restoring elastic member is a spring, which is installed on the top end of the inlet side of the wire gripper, and the movable pressing block is square. Pulling the movable pressure block up and exposing the inlet port requires a smaller volume, which makes the volume of the thread clamp smaller.

More preferably, a raised block is provided on the outer side of the movable pressing block. Lifting the movable pressing block by the raised block makes it easier to lift the movable pressing block and keep it for a longer lifting time.

Preferably, an inlet baffle is arranged at the foremost end of the inlet side of the wire gripper, and a through hole is arranged on the inlet baffle. The wiring head passes through the inlet baffle and enters the wiring hole through the through hole. In the non-working state, the inlet baffle can protect the movable pressure block and avoid damage to the movable pressure block by touching it.

Preferably, the diameter of the through hole is larger than the outer diameter of the terminal and smaller than the outer diameter of the cable of the terminal. The cable of the terminal head cannot pass through the through hole, so as to avoid the depth of the terminal head extending too deep, and the terminal head cannot touch the metal sheet.

Preferably, the metal sheet is installed on the wire gripper through a fastener, the metal sheet extends to the outside of the wire gripper and is provided with a connection hole at the end. The wire is connected with the metal sheet through the connection hole, which is more firm and firm. It is more convenient to replace damaged metal pieces by connecting with fasteners and wire clamps than using adhesives.

Preferably, the junction box is also provided with a number of empty connection clamps that are not connected to the wiring holes. When the tester is in use, there are redundant connectors. Due to the live debugging, the redundant connectors will also carry current, which is easy to cause damage to the operator, so insulation treatment is required. Inserting the redundant connector into the empty connection clamp will not form a loop with the automatic switch, will not affect the test, and will not cause damage to the operator. Compared with the use of tape insulation, the work efficiency is improved.

Preferably, the junction box is made of insulating material. The junction box made of insulating material is non-conductive, which can prevent the staff from being injured by the current when touching the junction box.

Compared with the prior art, the beneficial effects are: through the automatic reset and pressing function of the movable pressing block of the wire clamp, the wire head is quickly fixed in the wire insertion hole, which improves the work efficiency; avoids excessive tightening of screws. Damaged terminals; reduce staff working time on live sites and improve safety.
