Embodiment
With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 5, a kind of photovoltaic connector structure described in the present embodiment, include the male joint 2 and female joint 1 that coordinate grafting, described male joint, female joint internal fixtion are connected with cable 4, cable is positioned at male joint, female joint end-position is socketed with plug 9, inside be socketed with the plastics gaily decorated basket 10 beyond the Great Wall, the afterbody of male joint, female joint is threaded connector 14, threaded connector is connected with nut 3, while nut is connected with threaded connector, the plastics gaily decorated basket and interior plug is pressed on cable; Position adjacent with threaded connector in described male joint, female joint outside wall surface forms an annular step, the one-body molded 3-6 of having the trapezoidal dop 15 be equally spaced on annular step, the face that dop is relative with clockwise direction is inclined-plane, and another side relative with inclined-plane on dop is vertical with annular step; The end of described nut forms the end to end draw-in groove 31 coordinated with described dop near the position of inner circumferential.
The one end side one symmetrical molding of described female joint and male joint grafting has two plug sockets 11, form the spliced eye 13 of rectangle along female joint length direction in plug socket, the position of female joint side next-door neighbour's plug socket forms two recesses, and the position of the corresponding recess of female joint is one-body molded tamper baffle plate 12, tamper baffle plate coordinates the through hole of a formation rectangle with the wall of recess; Described male joint has two connection-pegs 21 coordinating grafting with described spliced eye with one end of female joint grafting is one-body molded, under the state of not stressing, form the angle of 8-15 degree between two connection-pegs, the end of connection-peg is one-body molded a trapezoidal Access Division; Side outwardly, Access Division comprises a planar portions 211 and an inclined plane part 212, and inclined plane part is positioned at the end position of Access Division, and planar portions is parallel with male joint length direction under the state of connection-peg, spliced eye cooperation grafting.The state of opening is under described connection-peg nature, when being connected with female joint, needs are suitably oppressed connection-peg in opposite directions and are made it slight curvature and could insert in spliced eye, ensure that connection-peg connection is firmly stuck in the end position away from male joint on plug socket in Access Division afterwards.
The end of cable is electrically connected with metal connector 7, and metal connector and cable junction are socketed with metal basket 8.One end of described male joint and female joint grafting and the position between two connection-pegs is one-body molded plug body, plug body is socketed with sealing ring 5, and internal face sealing ring and female joint being positioned at plug socket one end is sealed and matched.Metal connector in described female joint is tubular structure, and the inwall of this metal connector is fixedly connected with an Intranet circle 6, in the metal connector that the metal connector in described male joint is inserted in female joint and with Intranet circle interference fit.
During connecting cable, first nut, interior plug, the plastics gaily decorated basket are set on cable, subsequently metal connector are clamped on the core of cable end, put metal basket, then cable is inserted in male joint or female joint, nut is screwed on threaded connector; When using photovoltaic connector, insert after being aimed at spliced eye in female joint by the connection-peg in male joint, after being inserted into position, namely the end position of the Access Division of connection-peg end away from male joint on plug socket complete connection.Then need during dismounting can dismantle by specific purpose tool, this specific purpose tool has two parallel cuttings, and cutting inserts compressing Access Division from the through hole of female joint and plug socket end departs from, thus connection-peg is deviate from from spliced eye.
