Abstract
The invention discloses an anti-loose wire fastening assembly, which comprises a bolt and a nut, wherein the nut is matched with the bolt; an anti-loose cover sleeves a rod part of the bolt, and is in a conical form with a narrow upper part and a wide lower part; a plurality of limiting blocking strips vertically extend downwards at the bottom of the anti-loose cover; a plurality of limiting blocking grooves matched with the limiting blocking strips are formed in the upper end surface of the nut; and a wire blocking gap is formed in the bottom of the side wall of the anti-loose cover. The anti-loose wire fastening assembly has the beneficial effects of simple structure and reasonable design; the wire can be effectively prevented from swinging left and right to affect the bolt by the added anti-loose cover; loosening of the bolt is avoided; the safety is improved; the connected part of the wire can also be covered; and bolt corrosion and a short circuit caused by entering of rainwater are avoided.
Description
Technical field
The invention belongs to technical field of electric power, particularly a kind of locking off-type wire fastening assembly used on power circuit.
Background technology
At present, power circuit often adopt bolt fastened by wire, but there is a lot of power circuit to be out of doors, outdoor environment is comparatively complicated, often occur the situation of blowing and raining, the situation that power line lead can be bobbed and woven when blowing, the easy like this holding screw that causes gets loose, wire drops, and even causes electric power accident.
Summary of the invention
For solving above technical deficiency, the invention provides one and being less likely to occur to get loose, the locking off-type wire fastening assembly that fail safe is high.
The present invention is achieved by the following measures:
One of the present invention locking off-type wire fastening assembly, the nut comprising bolt and match with bolt, the bar portion cover of described bolt has anti-drop cover, described anti-drop cover is up-narrow and down-wide taper shape, and be extended with some spacing card articles bottom anti-drop cover straight down, the upper surface of described nut is provided with the spacing draw-in groove that some and spacing card article matches, and the sidewall bottom of anti-drop cover has card line breach.
The head bottom surface of above-mentioned bolt is provided with the groove of annular, and described anti-drop cover top is stretched in groove.
The interior side-wall surface of above-mentioned groove is the conical surface, and the tapering of this conical surface is less than the tapering of anti-drop cover sidewall.
Interior side-wall surface and the anti-drop cover top wall outer surface of above-mentioned groove are provided with anti-slip veins.
The invention has the beneficial effects as follows: structure is simple, reasonable in design, the anti-drop cover increased can effectively prevent wire from swinging on the impact of bolt, avoid bolt looseness, improve fail safe, but also the coupling part of wire can be covered, avoid because rainwater enters the bolt corrosion and short circuit caused.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is cross-sectional view of the present invention.
Wherein: 1 bolt, 2 nuts, 3 anti-drop covers, 4 spacing card articles, 5 card line breach, 6 spacing draw-in grooves, 7 grooves.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the present invention:
As shown in Figure 1, 2, one of the present invention locking off-type wire fastening assembly, the nut 2 comprising bolt 1 and match with bolt 1, adds anti-drop cover 3 in addition, what anti-drop cover 3 can stop wire swings on the impact of bolt 1, improves the fastness of bolt 1.
Anti-drop cover 3 is enclosed within the bar portion of bolt 1, anti-drop cover 3 is up-narrow and down-wide taper shape, and be extended with some spacing card articles 4 bottom anti-drop cover 3 straight down, the upper surface of nut 2 is provided with the spacing draw-in groove 6 that some and spacing card article 4 matches, and the sidewall bottom of anti-drop cover 3 has card line breach 5.The head bottom surface of bolt 1 is provided with the groove 7 of annular, and anti-drop cover 3 top is stretched in groove 7.The interior side-wall surface of groove 7 is the conical surface, and the tapering of this conical surface is less than the tapering of anti-drop cover 3 sidewall.Interior side-wall surface and the anti-drop cover 3 top wall outer surface of groove 7 are provided with anti-slip veins.
During use, first wire termination is peelled off insulated hull and be wrapped in bolt 1 bar portion below anti-drop cover 3, wire passes from card line breach 5.Then be screwed in nut by bolt 1 lower end, the spacing card article 4 of anti-drop cover 3 inserts in spacing draw-in groove 6, continues nut to tighten.After tightening, anti-drop cover 3 top is stretched in groove 7, and the interior side-wall surface due to groove 7 is the conical surface, and the tapering of this conical surface is less than the tapering of anti-drop cover 3 sidewall.
So anti-drop cover 3 can clamp by nut.Anti-slip veins on contact-making surface can make both not easily relative sliding occur.When wire swings, wire only can swing in card line breach 5, and its amplitude of fluctuation is restricted, and inserts in spacing draw-in groove 6 due to limited location card article 4, so anti-drop cover 3 can not rotate, therefore also just avoid the impact that bolt 1 is subject to wire swing.And terminal part covers by anti-drop cover 3, avoid and corrode and short circuit because rainwater enters the bolt 1 caused.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection range that also should be considered as this patent.
Claims (4)
1. a locking off-type wire fastening assembly, it is characterized in that: the nut comprising bolt and match with bolt, the bar portion cover of described bolt has anti-drop cover, described anti-drop cover is up-narrow and down-wide taper shape, and be extended with some spacing card articles bottom anti-drop cover straight down, the upper surface of described nut is provided with the spacing draw-in groove that some and spacing card article matches, and the sidewall bottom of anti-drop cover has card line breach.
2. locking off-type wire fastening assembly according to claim 1, is characterized in that: the head bottom surface of described bolt is provided with the groove of annular, and described anti-drop cover top is stretched in groove.
