Description of drawings
Fig. 1 is the structural representation of cable connector of the present invention.
Fig. 2 is the exploded view of cable connector public plug of the present invention.
Embodiment
As shown in Figure 1, the connector of present embodiment comprise the fixed cover 4 that has through wires hole with have a public plug be connected matrix 1, connecting matrix 1 be tubular, the one end seals, and high pressure list core seal head 5 is housed, and at the blind end lateral surface external screw thread is arranged.Fixed cover 4 is a tubular, and the one end is coniform through wires hole, and other end inboard has internal thread, is used for and is connected matrix 1 and has externally threaded blind end and be spirally connected.Be screwed a public plug 61 in the connection matrix 1, please be simultaneously with reference to Fig. 2.Public plug comprises tubular set casing 6, contact pin 7, last fixed cover 8, following fixed cover 9, ring-shaped rubber back-up ring 10 and has the lock ring 11 of opening.An alignment pin 13 is arranged on the set casing 6, corresponding alignment grooves is all arranged on the upper and lower fixed cover.The top of contact pin 7 and terminals insert respectively in the through hole of fixed cover 8 and following fixed cover 9, it is big that the diameter at contact pin 7 middle parts becomes in the past backward, formed first, the step surface of the second two annulars, diameter diminishes and forms the step surface of the 3rd annular then, last fixed cover 8 and following fixed cover 9 have through hole respectively, it is big that its diameter of the through hole of last fixed cover 8 becomes in the past backward, the corresponding annular table terrace of step surface of first and second annulars of formation and contact pin 7, make contact pin 7 tops insert when going up fixed cover 8, the first and second annular table terraces of contact pin are resisted against respectively on the first and second annular table terraces of fixed cover 8 through holes.The diameter of the diameter of following fixed cover 9 through holes and the tail wiring end of contact pin 7 is roughly the same, makes that the 3rd annular table terrace of contact pin 7 can be resisted against down on the end face of fixed cover 9 when contact pin 7 terminals inserted fixed cover 9.The diameter of through hole can make fixed cover 8 and following fixed cover 9 that contact pin 7 engagings are lived less than the diameter of the 3rd step surface like this on the following fixed cover, moves forward and backward to prevent contact pin 7.Last fixed cover 8 and following fixed cover 9 that contact pin 7 is lived in engaging are fixed together by screw 14.The be fixed annular protrusion of shell 6 front end inboards of last fixed cover 8 blocks, the rubber back-up ring 10 that following fixed cover 9 is assembled in set casing 6 outer annular groove blocks, and fixed cover 8 and following fixed cover 9 are fastened between set casing 6 interior annular projectioies and the rubber back-up ring 10.The opposite side of rubber back-up ring 10 is equipped with lock ring 11, and lock ring 11 adopts the mode of being spirally connected to be fixed in the set casing rear end.Lock ring 11 sides are not closed, leave an elongated breach with certain width, so that move into electric wire when installing.
Also be with one and rotatingly have an externally threaded quick attaching nut 3 connecting matrix 1 outside, be used to connect female, connect matrix 1 and sealing ring 2 is housed, be used for the seal of reinforced company's joint with the end outside that female is pegged graft.Also have the locking screw at fixed cover 4 with being connected the end that matrix 1 connects, by screwing in lock-screw 12, make fixed cover 4 and to be connected matrix 1 more fastening, bearing capacity is stronger.
During assembling, earlier contact pin 7 tops are inserted in the through hole of fixed cover 8, will descend the through hole of fixed cover 9 to be inserted in the terminals of contact pin 7 again, make fixed cover 8 and following fixed cover 9 engage firmly contact pin 7, with screw 14 upper and lower fixed cover is fixed together again.Then it is packed in the public plug set casing 6, fixed cover 8 is against on the annular protrusion in the set casing 6, the alignment pin 13 of set casing inboard is inserted in the alignment grooves corresponding on the upper and lower fixed cover.Again rubber back-up ring 10 is packed in the groove of set casing 6, make it block down fixed cover 9, the lock ring 11 of packing at last, then public plug assembles.
Cable passes the through wires hole of fixed cover 4, is electrically connected with the outside binding post of the high pressure list core seal head 5 that is connected matrix 1.The inboard binding post of high pressure list core seal head 5 then is electrically connected with contact pin 7 terminals on the public plug by lead.After connecting cable, public plug packed into connect in the matrix 1, and quick attaching nut 3 is enclosed within the groove in the connection matrix outside, it can be rotated freely in groove, but can not move up and down, to connect matrix 1 then and screw in the fixed cover 4, and in the locking screw, screw in lock-screw 12.During use,, make another connector that has female screw-in that is spirally connected gradually by rotating quick attaching nut.
From this embodiment as can be seen, because public plug is by connecting the high pressure list core seal head and the cable electric connection of matrix, and the top of contact pin and terminals keep apart by upper and lower fixed cover, when operation, can prevent that liquid from infiltrating, and makes connector of the present invention have good sealing property.In addition owing to adopt multiple fastening means, and the high pressure sealing head is housed in connector, thereby makes connector of the present invention have good resistance to pressure simultaneously.The structure of public plug of the present invention is easy to use simultaneously, is easy to dismounting.Public plug in the fast connector of present embodiment can be selected according to actual needs, for example 18 cores.
The foregoing description description of this invention is not that content of the present invention is done further to limit.One skilled in the art will understand that to be equal to replacement to what technical characterictic of the present invention was done, or corresponding the improvement, still belong within protection scope of the present invention.
