Connector is a kind of electronic devices and components comparatively common in the middle of the electronic engineering technology, and its Main Function is to connect and realize circuit output and being electrically connected in input process by connector, thereby makes complete machine bring into play predetermined function.Connector is indispensable parts in electronic equipment, is also extremely important electronic devices and components.In recent years, China high-end field gathers and analyzes by a large amount of complete machine failure phenomenons, reach a conclusion as " three or three rule ": 30% complete machine failure phenomenon is the electronic devices and components fault, and 30% electronic devices and components fault is the connector fault, particularly the information age, connector is very important in message transmitting procedure.
The connected mode of connector mainly contains direct insertion connection, bayonet coupling and is threaded three kinds.Wherein bayonet coupling is a kind of common reliably and rapidly connecting and separate mode; there are mechanical labour-saving characteristics: the plug connecting ring by rotation with bail; bail is slided along the helicla flute track of Socket casing link; by rotating band spiral fluted Socket casing; make it to cross the bail on the plug connecting ring, and cross the protruding point of helicla flute one end, enter blind mouthful of positioning end of spiral fluted; carry out clamping spacing, thereby realize the locking of connector plug and socket.
And, with regard to connector, at the aspects such as combination property of considering weight, machining, cost and product, the structural support multiselects such as socket link and plug connecting ring are shaped with coat with aluminum alloy materials and surface, bail multiselect stainless steel material.When the stainless steel bail slides along the helicla flute on Socket casing, due to the effect of ripple spring in the plug connecting ring, force of sliding friction is very large, and while particularly crossing the coat of helicla flute clamping position (being corner), force of sliding friction is larger.Because this frictional force becomes suddenly large, cause jack screw groove clamping position very easily to be worn and torn, go down for a long time, spiral fluted clamping position can be smooth-out, cause the bail of connector can skid off from the bail end slot under vibration condition, cause the improper disconnection that comes off of connector, thereby shorten the useful life of connector or connector was lost efficacy, and then affect the normal operation of complete machine.If the shell of Socket casing is selected wear-resisting stainless steel, the weight increase of product is larger on the one hand, and machine work difficulty on the other hand increases, and then causes the significantly increase of cost of material and processing cost etc.
Summary of the invention
Purpose of the present invention just is 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 present invention 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 the clamping position, spacing to the bail enforcement clamping screwed in described helicla flute.
Described wear-resisting pin is the stainless steel pin identical with material with bail.
Be provided with the circular groove in order to determine that the connector clamping puts in place on the described Socket casing link on blind mouthful of positioning end top of described spiral fluted.
The present invention, by wear-resisting pin is set on the helicla flute at the 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 present invention can still can keep good clamping to coordinate after connector plugs together repeatedly, makes the vibration resistance of the connector of bayonet connection type, shock resistance also greatly improve, and the connection reliability of connector improves thereupon.
The present invention is easy to processing and fabricating, and can make at least improve 100 times the mechanical endurance of connector, and 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 inboards, plug casing, be connected with ripple spring 8.When plug and socket are connected, the link of Socket casing 1 inserts the inboard of plug connecting ring 6, and withstands ripple spring 8, now, promote forward and rotary connector connecting ring 6, three bails 7 of its inboard 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 reliablely and stablely being connected with the link of Socket casing 1.
The top of blind mouthful of positioning end 5 of the helicla flute 2 on the 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 the visual observation to the bail 7 corresponding at vertical position with circular groove 4, illustrate that clamping puts in place, try position thereby reduce repeatedly twisting of spiral groove end, reduce the frictional dissipation between bail 7 and wear-resisting pin 3.
In the locking process of connector, the peak that 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 curvilinear path of camber line one side in whole helicla flute notch, therefore this clamping position is to bear the place of frictional force maximum in the connector connection procedure, 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 the angle theta of component=0 °, 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 interior clamping position of helicla flute because of wearing and tearing.
The present invention arranges the wear-resisting pin 3 of stainless steel in the clamping position, just make the hardness of the clamping position in the helicla flute 2 on the 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 all are greatly improved.
Experimental result shows, after adopting wear-resisting measure of the present invention, 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.
