Summary of the invention
The purpose of this utility model is just to provide a kind of wear-resisting Socket casing of connector, and to solve existing connector body housing link, because of the wearing and tearing of clamping position, reliably clamping is spacing, causes connector to connect problem loosening and that lost efficacy.
The utility model is achieved in that a kind of wear-resisting Socket casing of connector, on the outer round surface of the Socket casing link of connector, have around to and the equal corresponding consistent some helicla flutes of spiral angle, described spiral fluted one end is the openend of opening on Socket casing link edge, the described spiral fluted other end is that bail is implemented to blind mouthful of spacing positioning end of clamping, in the notch that connects blind mouthful of positioning end of described helicla flute, the end of camber line one side is fixed with wear-resisting pin, the nail bar periphery of described wear-resisting pin is slightly advanced by leaps and bounds in described spiral fluted notch, to form clamping position, spacing to the bail enforcement clamping screwing in described helicla flute.
Described wear-resisting pin is and the identical stainless steel pin of material for bail.
On the described Socket casing link on blind mouthful of positioning end top of described spiral fluted, be provided with the circular groove in order to determine that connector clamping puts in place.
The utility model, by wear-resisting pin is set on the helicla flute at Socket casing link, greatly improves the anti-wear performance of helicla flute clamping position, has improved thus the resistance to wear of Socket casing, and then has improved useful life and the connection reliability of connector.The utility model can still can keep good clamping to coordinate after connector plugs together repeatedly, and the vibration resistance of the connector of bayonet connection type, shock resistance are also greatly improved, and the connection reliability of connector improves thereupon.
The utility model is easy to processing and fabricating, and the mechanical endurance that can make connector at least improve 100 times, connection reliability at least improves 20 times, efficiently solves the hard nut to crack that bayonet coupling connector long-term unsolvedly wears no resistance, the life-span is low and connection reliability is poor.

Embodiment
Connector comprises two parts of plug and socket.As depicted in figs. 1 and 2, on the link outer round surface of Socket casing 1, have 2, three helicla flutes 2 of three helicla flutes around to consistent, spiral angle is consistent, and be uniformly distributed on the link outer round surface of Socket casing 1.One end of every helicla flute 2 is the openend of opening on Socket casing 1 link edge, and the other end is that bail 7 is implemented to blind mouthful of spacing positioning end of clamping, and helicla flute 2 can process with CNC milling machine.
As shown in Figure 3, on the inner headed face of plug connecting ring 6, on the contour at 120 °, interval, be evenly equipped with three bails 7, at the convex shoulder place of plug connecting ring 6 inner sides, plug casing, be connected with ripple spring 8.When plug and socket are connected, the link of Socket casing 1 inserts the inner side of plug connecting ring 6, and withstands ripple spring 8, now, promote forward and rotary connector connecting ring 6, three bails 7 of its inner side are screwed in respectively in three helicla flutes 2 on plug casing connecting ring 6.When bail 7 rotates to blind mouthful of positioning end 5 place of helicla flute 2 ends, can be blocked by the stainless steel formed clamping of wear-resisting pin 3 position, to realize locking, make connector plug connecting ring 6 realize and being reliablely and stablely connected with the link of Socket casing 1.
The top of blind mouthful of positioning end 5 of the helicla flute 2 on Socket casing link is provided with circular groove 4, when the end that rotates to helicla flute 2 when bail 7 is blind mouthful of positioning end 5 place, can be from visual observation to bail 7 corresponding at vertical position with circular groove 4, illustrate that clamping puts in place, thereby reduce repeatedly twisting of spiral groove end, try position, reduce the frictional dissipation between bail 7 and wear-resisting pin 3.
In the locking process of connector, the wear-resisting pin of stainless steel 3 present positions that are fixed on camber line one side in 2 blind mouthfuls of positioning ends of helicla flute, 5 notches are the peak of the curvilinear path of camber line one side in whole helicla flute notch, therefore this clamping position is in connector connection procedure, to bear the place of frictional force maximum, concrete force analysis situation as shown in Figure 4, when bail 7 rotates to the position A in groove, in 7 pairs of helicla flutes of bail, the normal pressure of the generation of camber line one side is N1, now
N1?=?Fcosθ
When bail 7 rotates to clamping position (being position B), the normal pressure that in 7 pairs of helicla flutes of bail, camber line one side produces is N2, now, and angle theta=0 ° of component, and cos0=1, so:
N2?=?Fcos0?=?F
Visible, N2 > N1.
Because force of sliding friction is directly proportional to normal pressure, therefore, when bail 7 moves to position B, force of sliding friction when its frictional force is greater than bail 7 and moves to position A.This namely very easily causes the main cause of connector Joint failure in the clamping position in helicla flute because of wearing and tearing.
The utility model arranges the wear-resisting pin 3 of stainless steel in clamping position, just make the hardness of the clamping position in the helicla flute 2 on Socket casing link strengthen, surface smoothness improves, improved thus the anti-wear performance of helicla flute clamping position, and suitably having reduced the frictional resistance between helicla flute clamping position and bail 7, useful life and the connection reliability of connector are all greatly improved.
Experimental result shows, after adopting wear-resisting measure of the present utility model, has effectively improved the resistance to wear of clamping position, can make at least improve 100 times the mechanical endurance of connector, and connection reliability at least improves 20 times.
