Embodiment
As depicted in figs. 1 and 2, in the preferred embodiment of explosion-proof connector of the present invention, explosion-proof connector comprises socket 100, and with the plug 200 of these socket 100 adaptive grafting.Described socket 100 comprises socket base 5 and dismountable tail-hood 2, offers a through hole 22 on the socket base 5, is provided with internal thread in the through hole 22, and through hole 22 middle parts are provided with a step 51, and through hole 22 is divided into two sections.Wherein, first section is used to connect tail-hood and is used for attachment plug 200 for 2, the second sections.
Tail-hood 2 is provided with boss, and outer wall of boss is provided with external screw thread, with adaptive being spirally connected of internal thread of 22 first sections of through holes.The edge of tail-hood 2 is provided with the breach of a plurality of circular arcs, after tail-hood 2 is screwed on the through hole 22, hold-down screw 1 passes breach and is screwed onto on the socket base 5, like this, even if in vibration environment, use, can not occur between tail-hood 2 and the socket base 5 becoming flexible yet, phenomenon such as disengagement, guaranteed the safety of using.
The conductive base pin 3 that plays electric action is arranged on the boss of tail-hood 2.With reference to Fig. 3, after tail-hood 2 was fixed in the socket base 5, the height of conductive base pin 3 was lower than the end face of socket base 5 near plug 200 1 ends.In the conductive base pin 3, zero line or earth pin 31 are higher than other conductive base pins 33.Refer again to Fig. 7, colored hurdle shell fragment 32 is housed on the conductive base pin 3, the conductive jack 23 of conductive base pin 3 and plug 200 closely contacts when guaranteeing to connect.
In order to improve the water resistance of this socket 100, in the preferred embodiment of the present invention, be provided with sealing ring 21 between tail-hood 2 and the through hole 22.Sealing circle 21 is nested with in the cover plate of tail-hood 2 and boss junction, is used to seal the slit between tail-hood 2 and the through hole 22.The benefit of detachable tail-hood 2 is that when damaging appearred in conductive base pin 3, it was just passable only to need to change tail-hood 2, has avoided the situation that in the past only caused whole socket to scrap because conductive base pin damages, and has reduced the expense of operation and maintenance.
As Fig. 1, Fig. 2 and shown in Figure 5, in the preferred embodiment of explosion-proof connector of the present invention, plug 200 comprises pilot hole seat 7, and plugging hole component and being provided with is received the Plug base 9 that connects hole 20.Wherein plugging hole component comprises jack pedestal 8 and is arranged on conductive jack 23 on this jack pedestal 8.Receiving and connecing hole 20 is through hole, along being disposed with three steps away from socket 100 directions: first step 91, second step 92, the 3rd step 93.
The conductive jack 23 of plugging hole component inserts in the pilot hole 71 that is arranged on the pilot hole seat 7, the radial clearance that keeps 0.5～1.5mm between the pilot hole 71 of conductive base pin 23 and pilot hole seat 7, preferred radial clearance is 1mm, the end play that keeps 2～5mm between jack pedestal 8 and the pilot hole seat 7, can guarantee that like this plugging hole component has certain movable space, thereby make that explosion-proof plug is easier to peg graft.
Step 51 in the through hole 22 on the socket 100 is provided with sealing ring 6 near one side of plug, closely cooperates with the end of plug pilot hole seat 7 near socket.
As Fig. 1 and shown in Figure 5, in the preferred embodiment of explosion-proof connector of the present invention, Plug base 9 one ends are provided with compressing member 19, compressing member 19 is a cylinder near Plug base one end, outer wall is provided with screw thread, connect adaptive being spirally connected of internal thread on 20 inwalls of hole with being arranged on to receive, between step 93 and compressing member 19, be provided with cushion block 25 and pad 26; The other end of compressing member 19 is six prisms, compressing member 19 axially is being provided with the through hole that is used to draw lead 16, six prisms are provided with breach away from plug one end, what cooperate with this breach is the casting die 18 of circular arc, the inwall of breach and casting die 18 is provided with the twice projection, match with the twice groove on being located at cable cover(ing) 15, casting die 18 is fixed on the breach of compressing member 19 by screw 17, cable cover(ing) 15 and lead 16 are pressed on together, the design that projection and groove match guarantees that phenomenon loosening and that come off in use can not appear in cable cover(ing) 15, simultaneously, cable cover(ing) 15 and lead 16 are pressed on together, prevent to avoid short circuit phenomenon to take place on the plugging hole component of rainwater in lead 16 infiltration Plug bases 9.
As Fig. 1, Fig. 2 and shown in Figure 5, in the preferred embodiment of explosion-proof connector of the present invention, plug 200 also comprises plug cover 11, and plug cover 11 is set on the outer wall of Plug base 9, and can rotate relatively.Plug base 9 front ends are provided with step 24, are used to the front end face of card tip cutting headgear 11, prevent that between the two mutually to wearing, plug cover 11 1 end outer walls are provided with external screw thread, with suitable being spirally connected of internal thread that is arranged on through hole 22 inwalls.In order to prevent that plug cover 11 from loosing from Plug base 9, a screw 12 is spirally connected in axial direction in Plug base 9 rear ends, the rear end face that is used to card tip cutting headgear 11, step 24 on the Plug base 9 is slightly larger than the length of plug cover 11 to the distance of screw 12, guarantee that plug cover 11 has certain move place, can rotation on Plug base 9 easily.
For the gap between sealing plug pedestal 9 and the plug cover 11, between Plug base 9 and plug cover 11, be provided with sealing ring 10, sealing ring 10 is set in the groove at middle part of Plug base 9 outer walls, be used to compensate the gap between jack sleeve 11 and the Plug base 9, to reduce the free gap between the two.
In the time of on socket 100 that plug 200 is pegged graft, conductive jack 23 on the initial plug-assembly is in released state with the conductive base pin 3 on the socket, earlier conductive base pin 3 is inserted in the pilot hole 71 of pilot hole seat 7, the rotary connector cover 11 then, when plug cover 11 screws in certain depth, ground wire in the conductive base pin 3 or zero line pin 31 contact with conductive jack 23 earlier, when continuing to screw plug cover 11, the live wire pin 33 of pin just begins to contact with conduction inserted sheet 23, finishes the conduction inserting state of whole socket and pin; When carrying out the hot drawing of plug, live wire pin 33 at first separates with conductive jack 23, is ground wire or zero line pin 31 again and the separating of conductive jack 23; This socket connector can effectively be avoided the generation of electric spark.
As Fig. 4 and shown in Figure 6, in the preferred embodiment of explosion-proof connector of the present invention, can insert on the socket accurately, fast in order to make plug, on tail-hood 2, be provided with a reference column 4, its height is a little more than conductive base pin 3; Simultaneously, be provided with pilot hole 14, peg graft with described reference column 4 adaptive location at the end face of pilot hole seat 7.
Because axial relief design by pilot hole seat and plugging hole component, and zero line or the ground wire conductive base pin structural design of slightly being longer than other conductive base pins, do not have electric spark when making between its socket and plug hot plug yet and produce, thus the inflammable and explosive substances of having stopped under inflammable and explosive environment, to ignite may; The conductive base pin of socket is arranged on dismountable tail-hood, and it is just passable only need to change conductive base pin when conductive base pin damages, and does not need socket integral body is scrapped, and has reduced the cost of operation and maintenance; Between the slit of each syndeton, be provided with sealing ring, can improve the water resistance of this syndeton greatly, and the use occasion of further having expanded this connector; In addition, adopt between plug and socket to be spirally connected, can prevent from use to occur virtual connection between the two or get loose, guarantee normal use.
