Description
Technical field
The utility model relates to plug field, particularly a kind of American cross two inserts.
Background technology
The 1-15R bis-specified according to national electrical manufacturers association inserts and is suitable for voltage 125V, electric current 15A, therefore the 10A that comparatively commonly uses of security requirement want high.But use in reality and find, easily there are breakage, wearing and tearing and bring very large potential safety hazard at swapping process in this plug, is therefore necessary the structural soundness improving this plug.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of American cross two to insert.
The utility model solves the technical scheme that its technical problem adopts:
A kind of American cross two insert, and comprise shell, the front end of described shell has zero line jack and firewire jack, and the upper and lower side of described case nose respectively has one and strengthens projection, and the rear end of wherein said reinforcement projection is provided with curve slope.
As a preference, described shell is built-in with the PBT internal frame for mounting terminal, wherein said PBT internal frame comprises upper cover and lower cover, described upper cover includes Mi shape part, the middle inside Mi shape part that is set forth in is provided with left and right clamping plate, and described lower cover comprises lower body, and described lower body is provided with left and right plate, the front end of described lower body is provided with terminal position plate, described terminal position plate has zero terminal location hole and fire line terminal location hole.
As a preference, outside, described left and right plate rear end is respectively arranged with inclined-plane.
As a preference, the upper end of described terminal position plate is provided with the folder position can blocking upper cover upper end, and the described lower surface of folder position flushes with the upper surface of upper cover.
The beneficial effects of the utility model are: this two slotting formula plug is by rational structural improvement, the design strengthening projection is particularly respectively set by upper and lower side, plug front is made to form a similar cross reinforced structure, coordinate built-in composite type PBT internal frame, greatly improve structural strength and the durability of plug, formula plug is inserted for powerful American 1-15R bis-significant.
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, Fig. 3 are the STRUCTURE DECOMPOSITION figure of PBT internal frame in the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of American cross two insert, and comprise shell 1, the front end of described shell 1 has zero line jack 11 and firewire jack 12, the upper and lower side of described shell 1 front end respectively has one and strengthens projection 2, and the rear end of wherein said reinforcement projection 2 is provided with curve slope 21.The rear end of shell 1 or lower end are connected with power line 3 and net tail 31.Strengthen projection 2 and a shell 1 front just formation similar cross structure, improve the intensity of plug for upper and lower two.And the curve slope 21 strengthening projection 2 not only improves the structural strength strengthening projection 2 itself, and be conducive to the demoulding strengthening projection 2 structure and even whole plug, be conducive to enhancing productivity.
Described shell 1 is built-in with the PBT internal frame 4 for mounting terminal, wherein said PBT internal frame 4 comprises upper cover 5 and lower cover 6, described upper cover 5 includes Mi shape part 51, the middle inside Mi shape part 51 that is set forth in is provided with left and right clamping plate 52,53, described lower cover 6 comprises lower body 61, described lower body 61 is provided with left and right plate 62,63, the front end of described lower body 61 is provided with terminal position plate 64, described terminal position plate 64 has zero terminal location hole 65 and fire line terminal location hole 66.Space place outside its middle left and right clamping plate 52,53 installs for terminal inserted sheet, and the space inside left and right clamping plate 52,53 is then inserted for left and right plate 62,63, has both facilitated the installation of two filling-in bit terminals, and has also facilitated the assembling of PBT internal frame itself.Described left and right plate 62,63 outside, rear end is respectively arranged with inclined-plane 67, and the installation of such upper cover 5 and lower cover 6 is just easier.
The upper end of described terminal position plate 64 is provided with the folder position 7 can blocking upper cover 5 upper end, and the lower surface of described folder position 7 flushes with the upper surface of upper cover 5, makes the installation of upper cover 5 and lower cover 6 more firm.
When actual production, its step is as follows:
Power line 3 through peeling opening, specifically according to manufacturing technique requirent;
Regulate cutting die and the blade of terminal machine, according to different distributions debugging pulling tension requirements;
Power line 3 carries out riveting with terminal inserted sheet respectively: the stripping mouth copper wire of power line 3 is put in the riveting district of terminal inserted sheet;
Again terminal inserted sheet is first assembled in the additional space district of upper cover 5; Then lower cover 6 and the own upper cover 5 assembled are assembled again;
Mould is contained in above injection molding machine, regulates the temperature of injection molding machine, pressure, time and the various process parameters such as cooling water, firing rate;
The PBT internal frame 4 that oneself has gone here and there is inserted into above the die cavity of mould, carries out injection mo(u)lding;
Again through the cooling of mould, be solidified into stable shell 1, from die cavity, take out shaping shell 1.
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.
