Embodiment
To the present invention be described more fully with reference to the accompanying drawing that shows the preferred embodiment of the present invention now.But the present invention realizes and should not be interpreted into multiple different form and is restricted to figure as described herein and looks embodiment.On the contrary, it is thorough and complete that these embodiment are provided as this disclosure, and will fully scope of the present invention be conveyed to those of ordinary skill in the art.Identical numeral is referring to identical parts in full, and uses band apostrophe symbol and the two apostrophe symbolic representation similar components of band in alternative embodiment.
At first, described according to electric connector 20 of the present invention with reference to Fig. 1-6.Electric connector 20 be used for a plurality of cables and schematically comprise conductivity body 21 (Fig. 6), insulating cover 25 and observe a plurality of windows 24 (Fig. 2) that opening 23 (Fig. 6) is aimed at the cut cable of conductivity body.Conductivity body 21 schematically has the general rectangular shape and can be formed by for example aluminium or other electric conducting material.
Each cable is admitted passage 26 to have cable and is entered opening 27 and enter the relative cut cable observation opening 23 (Fig. 6) of opening with cable.Conductivity body 21 also schematically has with each cable admits a pair of corresponding fasteners that passage 26 intersects to admit passage 32 (Fig. 6).Corresponding fasteners 33 also is located at each securing member and admits in the passage 32 (Fig. 6).Each securing member 33 can be the hex head fastener that for example has circular contact jaw.In addition, those of ordinary skills it will be appreciated that for each cut cable 31 and can use only securing member.
Each electric insulation transparent windows 24 can be positioned to contiguous corresponding cut cable and observe opening 23.Thereby window 24 provides a cover and allows from determining that visually naked cut cable 31 correctly is arranged in a corresponding cable and admits the passage 26.About transparent, its meaning is that the appropriate location of cut cable 31 is visual.Therefore, though window 24 can be transparent fully, the transparent partially transparent that comprises the appropriate location that still can see cut cable or translucent that also means.
Insulating cover 25 on the conductivity body 21 also has and is positioned at corresponding window opening 35 (Fig. 6) wherein, that aim at transparent windows 24.Insulating cover 25 preferably includes TPE in certain embodiments, thus the Unitarily molded conjunction of the adjacent portions of formation and transparent windows 24, and this is understandable for those of ordinary skill in the art.In a further embodiment, cover 25 can comprise other plastics or rubber insulation material.Each transparency window 24 can comprise mounting flange 37 and from its outward extending lens 38.This structure of transparent windows 24 and through hole (with the blind hole contrast) allows cut cable 31 further to extend through securing member 33, thereby causes more reliable connection, and this is understandable for those skilled in the art.
See that as may be in the decomposition view of Fig. 3 the clearest base portion ring 61 schematically is received within the upper end of cable inlet 41 and is used for cable end seals 45 fixing in place in the mode against the interior shoulder 48 of cable inlet 41.This layout also helps the manufacturing and the assembling of connector 20, and is to understand as those of ordinary skill in the art.
The plug tether assemblies 60 also comprise via second flexibility with 74 securing members that are connected to base portion ring 61 enter the plug 80.First flexible strap 73 and second flexible strap 74 stretch out from the opposite side of base portion ring 61.Enter plug 80 and schematically comprise two cappings 83 and relevant grasping member 84.Certainly in other embodiments, can use only capping 83.Securing member enters plug 80 and provides the selectivity passage so that allow fixation fastener 33 and environmental seal is provided subsequently.
As what those of ordinary skill in the art can easily understand that, plug tether assemblies 60 can be integrally molded as single by suitable material (such as TPE material or elastomeric material).Plug tether assemblies 60 can also be by for example two-stage or multistage TPE, single-stage TPE or TPE and polypropylene manufacturing.Certainly, other suitable material also can use.Therefore even do not using plug or removing plug so that they still together when entering temporarily therefore, when tether assemblies 60 helped making, they also kept together the other parts of plug 70,80 and connector 20 at plug.
In addition with reference to figure 7-11, further describe each part of cable end seals 45 now.Seal 45 comprises annular tear stop 49 and the outside ring body 46 that centers on the annular tear stop outside.Annular tear stop 49 schematically comprises a series of concentric annular ribs 47.The material of expectation seal 45 is flexible electric wire and/or cables to adapt to different size, and this is understandable for those of ordinary skill in the art.According to the size of electric wire or cut cable, tearing stopper 49 can be torn to concentric ring or rib 47, and the tightening seal that rib 47 forms with respect to the adjacent cable end is to understand as those of ordinary skill in the art.
Joint 48 schematically is connected to the inside of tearing stopper 49.Joint 48 dangles to corresponding cable inlet 41, for example as shown in Figure 6 from annular tear stop 49.In the illustrative examples of Fig. 7-10, joint 48 comprises the central opening 50 that passes wherein.In the alternative embodiment of the shown seal 45 ' of Figure 11, but opening 50 ' can be at first by fracturing diaphragm 54 sealings, to understand as those of ordinary skills.Among Figure 11 shown those other elements by the symbolic representation of band apostrophe and be similar to above-described those.
Joint 48 leads therein ideally and guides relative small dimension electric wire or cable and formation environmental sealing.For bigger cut cable, joint 48 can be torn off, and perhaps partly torn off, and cut cable will be with respect to 47 sealing of corresponding annular rib.In other words, the rib 47 of suitable dimension will seal as tearing stopper and with respect to cut cable, and will be to understand as those of ordinary skill in the art.These characteristics allow annular concentric portion to help the electric wire or the cable dimension of certain limit, and do not have unsuitable stress.In addition, seal 45 and tearing stopper 49 can be integrally molded as single by the material (such as silicone material) that expectation elasticity or elastic force degree are provided.
With reference to Figure 12 and 13, cable end seals 45 is described now in addition " another embodiment.In this embodiment, do not have joint, but a tearing stopper 49 " concentric rib or encircle 47 " extend into middle section.Tearing stopper 49 " by outside ring body 46 " be loaded with.Look among the embodiment seal 45 at figure " have a central opening 50 ", but in other embodiments, but opening can be at first by the fracturing diaphragm sealing, just as one of ordinary skill in the art understand.
Method of the present invention aspect relates to the method that is used to make electric connector 20, comprises forming plug tether assemblies 60 and it being attached to each cable inlet 41, as mentioned above.Another method relates to be made as mentioned above cable seal 45 and/or it is positioned in the still aforesaid cable inlet 41.Certainly, based on connector described herein, the present invention also can imagine other method.
Further feature of the present invention can be with reference to common co-pending application (title: ELECTRICALCONNECTOR INCLUDING CABLE END SEAL ANDASSOCIATED METHODS (electric connector and the correlation technique thereof that comprise cable end seals), agent docket: No.64570, its full content is bonded to here by reference) and above-mentioned U.S. Patent No. 7,144,279 and 7,160,146 (its full content is bonded to here by reference) are appreciated that other characteristics of the present invention and advantage.In fact, those of ordinary skill in the art benefits from the instruction of front description and relevant drawings, will associate many changes of the present invention and other embodiment.Therefore, be to be understood that the present invention will be restricted to described specific embodiment, is intended to comprise other modification and embodiment within the scope of the invention.
