Description
Technical field
The utility model relates to a kind of electric connector.
Background technology
Rainproof moisture-proof is one of important indicator of electric connector three-proof design, and the quality of Rainproof moisture-proof performance directly determines the quality of the dielectric voltage withstand performance of electric connector, and this just requires that electric connector accomplishes that all-directional rain-proof designs, and eliminates the interface channel that all exist.At present, though existing connector also carries out waterproof design, complex environment demand cannot be adapted to, still there is leakage hidden trouble., there is many places leak paths, as shown in Figure 1 in existing electric connector.
Utility model content
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of structure simple rain proof type electric connector, complied with the requirement of complex environment to electric connector Rainproof moisture-proof performance, solve connector because of rainproof not good cause leak water problem.
A kind of rain proof type electric connector, cable hood, handwheel, thick washer, thin packing ring, sealing ring, clamping screw, briquetting, cable sealing ring, packing ring, cable cover cap, O RunddichtringO, screw, casing, dust cover sealing ring and dust cover; Clamping screw inserts the apical pore of cable hood, clamping screw overlaps sealing ring successively, thin packing ring, thick washer, handwheel, by the effect also tightly reaching crush seal circle of handwheel; Briquetting is put into bottom the line outlet of cable hood, then puts into cable sealing ring, packing ring, carrys out compression cable sealing ring by being screwed into cable cover cap; The line outlet of cable hood is circular line outlet; Casing is formed seal groove and tapped blind hole, O RunddichtringO is enclosed within the seal groove of casing, load onto cable hood and compress O RunddichtringO, screw is passed the through hole on cable hood and is screwed in the tapped blind hole of casing with attached cable cover and casing; In the seal groove of dust cover, load dust cover sealing ring, by the connection of clamping screw and dust cover, make casing compress dust cover sealing ring.
The utility model compared with prior art beneficial effect is: the utility model by sealing ring compression seal principle, protects the leak paths of all existence: 1. by increasing sealing ring after simple change, can add sealing ring protection; 2. be similar to the structure of tapped through hole, changing through hole is blind hole; 3. square line outlet not easily protects, and changing its structure is that mouth appears in circle; Thus effectively can solve the rainproof problem of connector, improve product Practical Performance, improve reliability.
Accompanying drawing explanation
Leak paths two-dimensional structure model is there is in Fig. 1 before improving;
Fig. 2 is the two-dimensional structure model schematic after the utility model improves.
Embodiment
As shown in Figure 2, rain proof type electric connector of the present utility model, comprises cable hood 1, handwheel 2, thick washer 3, thin packing ring 4, sealing ring 5, clamping screw 6, briquetting 7, cable sealing ring 8, packing ring 9, cable cover cap 10, O RunddichtringO 11, screw 12, casing 13, dust cover sealing ring 14 and dust cover 15; Clamping screw 6 inserts the apical pore of cable hood 1, clamping screw 6 overlaps sealing ring 5 successively, thin packing ring 4, thick washer 3, handwheel 2, by the effect also tightly reaching crush seal circle 5 of handwheel 2; Briquetting 7 is put into bottom the line outlet of cable hood 1, then puts into cable sealing ring 8, packing ring 9, carrys out compression cable sealing ring 8 by being screwed into cable cover cap 10; The line outlet of cable hood 1 is circular line outlet; Casing 13 is formed seal groove and tapped blind hole, O RunddichtringO 11 is enclosed within the seal groove of casing 13, load onto cable hood 1 and compress O RunddichtringO 11, screw 12 is passed the through hole on cable hood 1 and is screwed in the tapped blind hole of casing 13 with attached cable cover 1 and casing 13; In the seal groove of dust cover 15, load dust cover sealing ring 14, by the connection of clamping screw 6 with dust cover 15, make casing 13 compress dust cover sealing ring 14.
Leak paths 1 is eliminated: passage 1 is present in the cooperation place of cable hood 1 and clamping screw 6, and eliminate this passage only need increase sealing ring 5 at clamping screw 6 and the junction of cable hood 1.Sealing ring 5 on clamping screw 6 overlaps successively, thin packing ring 4, thick washer 3, handwheel 2, by the effect also tightly reaching crush seal circle 5 of handwheel 2, can eliminate leak paths 1.
Leak paths 2 is eliminated: leak paths 2 is due to the generation of line outlet inserts cooperation leakiness, and this passage not easily passs through increases sealing gasket elimination.For this reason, need change square line outlet is circular line outlet: briquetting 7 is put into bottom the line outlet of cable hood 1, then loads cable sealing ring 8, packing ring 9 successively, by being screwed into cable cover cap 10 and also tightly carrying out compression cable sealing ring 8, reaches the effect eliminating leak paths.
Leak paths 3 is eliminated: leak paths 3 is caused by tapped through hole, and eliminating the best mode of passage 3 is that to change tapped through hole be tapped blind hole.
Leak paths 4 is eliminated: leak paths 4 is prevalent in all kinds of connector, is owing to only simply plugging together between cable hood and casing, does not take any seal approach to cause.In order to eliminate this passage, casing 13 increasing seal groove, loading O RunddichtringO 11, when plugging together cable hood 1, realizing sealing effectiveness by the extruding plugging together cable hood 1 pair of O RunddichtringO 11.
Leak paths 5 is eliminated: this passage plugs together or uses at headstock during dust cover and produces.Eliminate passage 5 to have come plugging together end face increase sealing gasket.
The utility model is compressed sealing ring or sealing gasket by two parts, utilizes decrement to eliminate fit clearance between two objects, makes it to reach sealed waterproof effect; The communicating passage that connector is inner and outside can be eliminated everywhere.
The content be not described in detail in the utility model specification belongs to the known technology of those skilled in the art.
