Description
Technical Field
The utility model relates to a protector is prevented puncturing by electron belongs to puncture protector technical field.
Background
The breakdown protector is a circuit protector for preventing breakdown short circuit from causing larger loss. In an electric power system, a breakdown fuse is mainly used for secondary side (low-voltage side) overvoltage protection of an indoor and outdoor voltage transformer to prevent high voltage from being connected in series into a secondary circuit, and the secondary circuit voltage rise caused by the circuit causes damage to secondary equipment and human bodies; or as overvoltage protection for other consumers. The breakdown fuse is grounded, so that the condition can be effectively prevented (the breakdown can be realized by hundreds of volts), and the breakdown fuse can ensure the insulation with the ground when the device works normally.
The terminal and the wire of the circuit board in the existing breakdown protector are connected by spot welding or are screwed by workers manually, so that the connected wire is very insecure, the wire is generally thin and can be broken frequently, the protector can not work normally, electric leakage and other conditions occur, and great accidents and great loss can be caused for a long time; the protector has short service life and is very dangerous, and the life safety of workers cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a breakdown protector is prevented to electron is provided.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides a protector is prevented puncturing by electron, it includes the casing, the inside circuit board that is equipped with of casing, be equipped with the terminal on the circuit board, the bottom is equipped with many pole settings in the casing, and it has a plurality of business turn over line mouths to open on the lateral wall of casing, is equipped with the thread tension device between pole setting and the business turn over line mouth in the casing, and the one end of thread tension device is passed through the spring and is opened on the casing and have the inside wall of business turn over line mouth fixed.
The wire clamping device is a semicircular body formed by two quarter round blocks, the lower ends of the two quarter round blocks are connected through a hinge, a curved groove is formed in the side face of one quarter round block, and a protruding strip corresponding to the groove is formed in the other quarter round block.
The groove is internally provided with a rubber layer, and the outer wall of the convex strip is provided with a rubber layer.
The lower end of a hinge at the lower end of the wire clamping device is fixedly connected with the sliding block, and a sliding groove corresponding to the sliding block is formed in the bottom in the shell.
The utility model has the advantages that: the utility model discloses an inside pole setting and the wire holder of being equipped with of casing, and the wire holder passes through the spring and links to each other with the inside wall of shell is fixed that it has the business turn over line mouth to open on the casing, and the pole setting can twine the wire, again with the wire extrusion press from both sides tightly between recess and the sand grip in the wire holder, makes the wire can not pulled apart, more safe and reliable in the use, increase the life of protector.
