The embodiment of the invention provides an aluminum alloy flat cable for a light-weight new energy automobile and a connector thereof, and further comprises a wrapping layer 2, wherein the wrapping layer 2 wraps the outside of an aluminum row cell 1, and a shielding armor layer 3 wraps the outside of the wrapping layer 2.
The nominal section area of the aluminum row battery cell 1 is 20mm 2 ～630mm 2 The cross section of the material is rectangular or elliptical, and the ratio of the width to the thickness is 4.0-8.0.
Compared with the traditional aluminum cable, the material of the wrapping layer 2 is changed, so that the cable can be produced in a traditional mode, the degree of change is small, and the practicability of the cable is guaranteed.
Specifically, the wrapping layer 2 is made of polyvinyl chloride, polyethylene, nylon, TPE or polyurethane foam.
During operation, the polyurethane foam layer itself has the foam space when using, when the electric core calorific capacity is great, the polyurethane foam can take place to expand this moment, the space can increase this moment, the air heat directly can contact with shielding armor 3 through the space, thereby accelerate its radiating effect, when external temperature is lower, when needs keep warm this moment, the space can diminish, thereby reduce air exchange, make the radiating effect of cable variation, the contrary can keep warm promptly, thereby reduce the influence that the cable received the temperature, the change appears in the resistivity, influence its power transmission.
Specifically, the cable connector is characterized by comprising a cable connector; still include the parcel mechanism 4, the cable joint sets up the end at the electric core 1 is arranged to the aluminium, parcel mechanism 4 sets up between shielding armor 3 and cable joint, parcel mechanism 4 includes the elastic metal bending plate 46, the both ends of elastic metal bending plate 46 are connected with elastic ring 41, the elastic metal bending plate 46 divide into upper shed extrusion part 45 and lower shed extrusion part 47, be provided with stopper 44 in the upper shed extrusion part 45, insert extrusion rod 43 between stopper 44 and the upper shed extrusion part 45, extrusion rod 43 and elastic ring 41 connect.
During operation, change the mode that current through pyrocondensation pipe to wrap up cable joint and cable into adopting this parcel structural mechanism and wrap up between cable and the connector, when adopting this parcel mechanism 4 when wrapping up, owing to adopt spring steel material, and the shape is folding form, all can leave the clearance between every layer, when the cable outwards expands, can extrude each other between the spring steel, but owing to leave the clearance, make between spring steel layer and the layer can not appear the clearance, thereby make the cable skin carry out the thermal expansion and can not lead to the fact the influence to parcel mechanism 4, guarantee the parcel effect, simultaneously at the in-process of using, spring steel inwards extends the extrusion throughout, guarantee the confliction power between parcel mechanism 4 to the cable, thereby guarantee the effect of compressing tightly, when the shrinkage phenomenon appears, the spring steel is originally for extrudeing the form this moment, after the clearance appears between cable and the spring steel, spring steel resets and guarantees that spring steel can be contradicted all the cable skin, though the phenomenon can also appear, but the shrinkage ratio compression ratio is less than the compression ratio, guarantee the effect, and when carrying out the crimping to spring steel and cable, because inside is provided with the connecting rod, every adjacent connecting rod can extend, make the contact with each initial spring end of adjacent layer can all guarantee the contact with each other spring effect.
Specifically, the upper opening pressing portions 45 and the lower opening pressing portions 47 are disposed at intervals, and in the initial state, every two adjacent upper opening pressing portions 45 are disposed in a staggered manner.
In operation, the elastic metal bending plate 46 can be produced by a common bending mode in the mode of the structure, and the production requirement is low.
Specifically, a lower connection block 42 is connected between the bottoms of the two adjacent upper opening extrusion parts 45, and the lower connection block 42 is made of an elastic material.
During operation, when carrying out the crimping through crimping mechanism, can contradict each other between at first adjacent extrusion rod 43, but because extrusion rod 43 highly different for can carry out the displacement when high extrusion rod 43 receives the extrusion, thereby make adjacent extrusion rod 43 be in same height, guarantee the extrusion parcel nature to cable shielding armor 3.
Specifically, the upper opening pressing portion 45 and the lower opening pressing portion 47 are hollow.
During operation, owing to be provided with the space, this elastic metal bending plate 46 is by the extrusion state under the initial condition for inside space reduces, when the cable receives the air influence to contract with cold, appears the space between cable and the elastic metal plate this moment, and the elastic metal plate resets, thereby contradicts shielding armor 3 surface all the time, reduces the possibility that the clearance appears, when the thermal expansion appears, has the space in the elastic metal bending plate 46 this moment, makes elastic metal bending plate 46 still can extrude, thereby can not influence the cable and take place normal physical change.
The working principle is as follows; firstly, the cable is connected with a cable connector, then an elastic metal bending plate 46 is sleeved between the cable and the cable connector, then the spring metal bending plate is crimped through a crimping tool, when the heat productivity of a battery core is relatively large in use of the cable, polyurethane foam expands at the moment, gaps are enlarged, air heat directly contacts with a shielding armor layer 3 through the gaps, so that the heat dissipation effect is accelerated, when the external temperature is low, heat preservation is needed at the moment, the gaps are reduced, so that air exchange is reduced, the heat dissipation effect of the cable is poor, otherwise, the cable can be preserved, so that the influence of the temperature on the cable is reduced, the change of resistivity is caused, the power transmission of the cable is influenced, meanwhile, when the thermal shrinkage is carried out, when the wrapping mechanism 4 is used for wrapping, due to the adoption of a spring steel material, and the shape is folded, gaps are reserved between every two layers, when the cable expands outwards, the spring steels can extrude each other at the moment, but due to the gaps, gaps can not appear between the spring steel layers, so that thermal expansion of the outer layer of the cable can not influence the wrapping mechanism 4, the wrapping effect is ensured, meanwhile, in the using process, the spring steels always extend inwards to extrude, the abutting force of the wrapping mechanism 4 on the cable is ensured, the compacting effect is ensured, when the cold shrinkage phenomenon occurs, the spring steels are initially extruded, after the gaps appear between the cable and the spring steels, the spring steels reset to ensure that the spring steels always abut against the outer layer of the cable, the cold shrinkage phenomenon also occurs, but the cold shrinkage ratio is smaller than the compression ratio, the effect is ensured, and when the compression is performed between the spring steels and the cable, because the inside connecting rod that is provided with, every adjacent connecting rod can contradict each other to make the spring steel of adjacent layer have a tensile effect, guarantee that every spring steel's contact end can all be with the outer contact of cable, guarantee initial contact effect.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
