Description
Technical field
The utility model relates to connecting terminal technical field, specially a kind of connecting terminal for over-voltage protector.
Background technique
Overvoltage refers to that peak value is greater than any voltage for operating normally the corresponding peaks of lower maximum steady state voltage, in engineering,
It refers to that all may be to the hurtful dangerous voltage of equipment, therefore in engineering, although some equipment that are greater than operate normally electricity
Voltage crest value but be not enough to jeopardize equipment normal work overvoltage be left out.
The existing connecting terminal for over-voltage protector is inserted into hexagonal slot using die nut and rotates bolt,
Cable is compressed by bolt bottom end, so that cable closely compresses arc copper sheet, because of arc copper sheet bottom side welding over-voltage protector
Internal circuit realizes cable and over-voltage protector circuit connection, but bolt rubs with contact cable in dynamic in rotary course
It wipes, it is easy to by cable spinning to avris, bolt be caused only to push down the sub-fraction of cable, therefore cable lower surface can not be made
Arc copper sheet is steadily contacted.
Utility model content
The purpose of this utility model is to provide a kind of connecting terminals for over-voltage protector, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of wiring for over-voltage protector
Terminal, including arc copper sheet, side welding has wolfram steel arc panel in the inner wall front of the arc copper sheet, the wolfram steel arc panel
Lower surface welding has a copper arc panel, and welding has a transverse slat on the upside of the inner wall front of the arc copper sheet, inside the middle side of the transverse slat
Equipped with bolt hole, the internal helicoid of the bolt hole is equipped with bolt, and the upper end of the bolt is fixedly connected with plectane.
Preferably, the lower surface of the copper arc panel is uniformly provided with copper raised line.
Preferably, hexagonal slot is equipped with inside the upper end of the plectane.
Compared with prior art, the utility model has the beneficial effects that this is used for the connecting terminal of over-voltage protector, spiral shell
Bolt is rotated down in bolt hole, and bolt lower end constantly compresses side in the upper surface of wolfram steel arc panel, drives downside copper arc panel
Middle side and two sides, which are bent downwardly, compresses cable, contacts cable upper surface by copper raised line, so that cable upper surface and copper arc panel
Lower surface cooperates resistance to increase, and limitation cable horizontally slips, due to table on the arc-shaped compress cable of curved copper arc panel
Face, so that cable lower surface is stable and is closely adjacent to the interior lower end of arc copper sheet, it is relatively direct to compress cable with bolt
Method, more firm makes cable lower surface that arc copper sheet be steadily contacted.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on
Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to the utility model
Limitation.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of technical solution: a kind of wiring for over-voltage protector
Terminal, including arc copper sheet 1, side welding has wolfram steel arc panel 2 in the inner wall front of arc copper sheet 1, and wolfram steel has curved well
Bent recovery capability, it is not easy to break, wolfram steel arc panel 2 with a thickness of 0.8 millimeter, when middle part bolt 7 rotation compress wolfram steel arc panel 2
Upper middle side part, maximum can make wolfram steel arc panel 2 press to the place apart from 0.1 millimeter of 1 inner lower of arc copper sheet, wolfram steel arc
The lower surface welding of plate 2 has copper arc panel 3, and 3 area of copper arc panel is identical as wolfram steel arc panel 2, because the material of copper arc panel 3 is
Copper increases cable and arc when the lower end in contact cable of copper arc panel 3, it can be achieved that cable upper surface is electrically connected with arc tube plate 1
The inner wall front upside welding of 1 electrical conduction area of copper sheet, the decline of electrical conduction resistance, arc copper sheet 1 has transverse slat 5, the middle side of transverse slat 5
Inside is equipped with bolt hole 6, and the internal helicoid of bolt hole 6 is equipped with bolt 7, and the upper end of bolt 7 is fixedly connected with plectane 8.
Refering to fig. 1 and Fig. 3, the lower surface of copper arc panel 3 are uniformly provided with copper raised line 4, when copper raised line 4 is by the lower press-bending of bolt 7
It is bent and when contacting cable, cable upper surface is contacted by copper raised line 4, so that cable upper surface and 3 lower surface of copper arc panel cooperate
Resistance increases, and limitation cable horizontally slips.
It is equipped with hexagonal slot 9, can be inserted into die nut in hexagonal slot 9 with Fig. 2, the upper end inside of plectane 8 refering to fig. 1,
To rotate bolt 7.
When the utility model is specifically implemented: cable is inserted on the downside of 1 front side copper arc panel 3 of arc copper sheet, by hexagonal
It is rotated clockwise in spanner insertion hexagonal slot 9, so that bolt 7 is rotated down in bolt hole 6,7 lower end of bolt is constantly compressed
Side in the upper surface of wolfram steel arc panel 2 then drives side and two sides in downside copper arc panel 3 to be bent downwardly and compress cable, passes through
Copper raised line 4 contacts cable upper surface, so that cable upper surface and 3 lower surface of copper arc panel cooperation resistance increase, limitation cable is left
Right sliding, because the material of copper arc panel 3 is copper, when the lower end in contact cable of copper arc panel 3, it can be achieved that cable upper surface and arc
Cylinder plate 1 is electrically connected, and increases cable and 1 electrical conduction area of arc copper sheet, due to curved copper arc panel 3 arc-shaped compress electricity
Cable upper surface, so that cable lower surface is stable and is closely adjacent to the interior lower end of arc copper sheet 1, it is relatively direct to be supported with bolt 7
The method of voltage cable, more firm makes cable lower surface that arc copper sheet 1 be steadily contacted.
