Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the bent plug of posture three in a kind of U.S. rule one.
The utility model solves the technical scheme that its technical problem adopts:
The bent plug of posture three in a kind of U.S. rule one, comprise shell, be positioned at the internal mold of shell and be arranged on the Inner frame of internal mold front end, the front end of described internal frame is provided with terminal, described terminal includes zero line inserted sheet, live wire inserted sheet and ground wire intubate, the lower end of described internal mold is connected with power line, the rear side of described shell is provided with radian face, and the rear end of described terminal is connected with sheet in turn and narrows position and riveting pipe, is carved with screw thread inside described riveting pipe.
As a preference, position between zero line inserted sheet, live wire inserted sheet, rear end of described internal frame is provided with vertically extending trapezoidal reinforcement.
As a preference, position between zero line inserted sheet, live wire inserted sheet, front end of described internal frame has the groove group of horizontal-extending.
As a preference, position, the hole place that the rear end of described internal frame is installed for ground wire intubate is provided with the back-off that can block ground wire intubate.
As a preference, be integrated injection mo(u)lding between described internal mold and Inner frame, described internal mold and Inner frame adopt polyvinyl chloride manufacture.
As a preference, on rear side of described internal mold, upper end has centre hole.
As a preference, on rear side of described internal mold, lower end has briquetting hole.
As a preference, the material of described shell is polybutylene terephthalate (PBT).
The beneficial effects of the utility model are: this plug is by rational structural improvement, the terminal structure of position is particularly narrowed by band sheet, coordinate the integral structure of Inner frame, inner membrance, the riveting of terminal is made to require correspondingly to reduce, save original riveted terminal operation and be about half the time, and the problem that the length sheet solving inserted sheet differs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model;
Fig. 2 is the stereogram of internal model structure in the utility model;
Fig. 3, Fig. 4 are the stereograms of Inner shelf structure in the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the bent plug of posture three in a kind of U.S. rule one, comprise shell 1, be positioned at the internal mold 2 of shell 1 and be arranged on the Inner frame 3 of internal mold 2 front end, be integrated injection mo(u)lding between wherein said internal mold 2 and Inner frame 3, described internal mold 2 and Inner frame 3 adopt polyvinyl chloride manufacture.The material of described shell 1 is polybutylene terephthalate (PBT).After concrete Inner frame 3 carries out disposable riveting wiring, and then be injection molded into internal frame internal mold 2, then injection molded is shell 1, is namely injection molded into a complete plug, makes the structure of plug compacter and firm.The front end of described Inner frame 3 is provided with terminal 4, described terminal 4 includes zero line inserted sheet 41, live wire inserted sheet 42 and ground wire intubate 43, the lower end of described internal mold 2 is connected with power line 5, the rear side of described shell 1 is provided with radian face 11, the rear end of described terminal 4 is connected with sheet in turn and narrows position 44 and riveting pipe 45, is carved with screw thread inside described riveting pipe 45.Sheet narrows position 44 can play positioning action to terminal 4, and especially for one-time formed plug construction, more can ensure that terminal 4 can not loosen, especially for more easily there is the curved plug that terminal is different in size, the meaning of this improvement is larger.
Position between zero line inserted sheet 41, live wire inserted sheet 42, rear end of Inner frame 3 described in Fig. 3, Fig. 4 is provided with vertically extending trapezoidal reinforcement 31, plays and strengthen Inner frame 3 steadiness, more can ensure that terminal 4 can not loosen.Position between zero line inserted sheet 41, live wire inserted sheet 42, front end of described Inner frame 3 has the groove group 32 of horizontal-extending, just forms the structure of similar reinforcement, can strengthen Inner frame 3 steadiness equally, more can ensure that terminal 4 can not loosen between groove group 32.
Owing to finding in practice, the most easily there is the inappropriate situation of terminal mounting location in ground wire intubate 43, namely ground wire intubate 43 extension elongation is defective, therefore, position, the hole place that the rear end of described Inner frame 3 is installed for ground wire intubate 43 is provided with the back-off 33 that can block ground wire intubate 43, positions ground wire intubate 43.
With reference to Fig. 2, on rear side of described internal mold 2, upper end has centre hole 21, can avoid occurring when injection moulding internal mold 2 and internal frame 3 glue phenomenon of overflowing.In addition, on rear side of described internal mold 2, lower end has briquetting hole 22, can push down the wire rod of power line 5 by mating mold briquetting, avoid terminal 4 askew by wire rod band in injection moulding process.
When actual production, its step is as follows:
1) power line 5 is through peeling opening (according to manufacturing technique requirent);
2) cutting die and the blade of terminal machine is regulated, according to different distributions debugging pulling tension requirements;
3) power line 5 carries out riveting with Inner frame 3 respectively: the riveting pipe 45 li of Inner frame 3 put into by the stripping mouth copper wire of power line 5;
4) internal mold mould is contained in above injection molding machine, regulates the temperature of injection molding machine, pressure, time and cooling water, the various process parameters such as firing rate;
5), above mould bar Inner frame 3 good for own riveting being inserted into mould, injection mo(u)lding is carried out;
6) again through the cooling of mould, be solidified into stable internal mold 2, from die cavity, take out shaping internal mold 2, so far complete first time injection molded;
7) external mold mould is contained in above injection molding machine, regulates the temperature of injection molding machine, pressure, time and cooling water, the various process parameters such as firing rate;
8), above the mould bar internal mold of own injection formed being inserted into external mold mould, injection mo(u)lding is carried out;
9) again through the cooling of mould, be solidified into stable shell 1, from die cavity, take out shaping plug, so far complete second time injection molded.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.
