Abstract
The invention discloses a terminal jacket of a power lead-acid battery terminal for electric vehicles, which consists of an inner jacket and an outer jacket, wherein the inner jacket is sheathed into the lower part of the terminal; a first shim is arranged between the inner jacket and a battery casing; the outer jacket sheaths the terminal and a copper ring inside, and is in fit connection with the inner jacket through threads arranged on the inner jacket and the outer jacket. The terminal jacket disclosed by the invention can not only effectively avoid potential safety hazard caused by short-circuit leakage when the electric vehicles travel in severe weather and environment with poor road conditions, such as miriness, seeper and the like, but also effectively avoid two-pole slight short-circuit of a monomer battery, casing burning and the like. For users of the integral vehicle, the invention can overcome the defect of high use cost caused by removing the battery.
Description
Technical field
The present invention relates to lead acid accumulator two gate terminal, the hermetically sealed insulated terminal sheath of especially a kind of electric vehicles power lead acid accumulator.
Background technology
The use of electric automobile power battery; The pure electric vehicle more than 90% of especially present occuping market; Electronic special vehicle etc.; Because the security and stability and the fancy price of lithium ion battery, cause most of car load producer in design with when producing motor vehicle, big close power-type lead-acid battery in all using.Can be fit to the power lead-acid battery that car load uses at present, what basically all adopt is copper core terminal, and the copper conductor that connects certain diameter through internal thread copper core terminal is connected on the motor and controller of car load.Because domestic pure electric vehicle still belongs to the starting stage; Most of car load producer to being connected between connecting line copper tip and the copper tip of drawing from internal, only uses general rubber sleeve mostly; Be enclosed within on connecting line copper nose and the terminal bolt, prevent to contact the conductor electric leakage.But this rubber sleeve can not carry out complete insulated enclosure to the part of exposing out on accumulator terminal and the connecting line copper nose, same electric leakage and the self-discharge phenomenon of taking place easily in the car load use.Only adopting of having carried out insulating protection to the fastening bolt cap on the terminal, and the leak electricity short-circuit accident takes place more easily.Especially vehicle is running into the muddy adverse circumstances of rainy day or road; Because in order to reduce the center of gravity of car load, improve security and stability, most of batteries all are placed on the chassis of car load; Again because the battery charging and discharging heat radiation can select to open the air port to the machine frame that carries battery.Rainwater just is penetrated into frock inside easily with muddy like this, in case muddy water has covered on accumulator terminal and the shell, just very easily causes gently then self discharge between storage battery two gate terminal, and is heavy then short circuit dischange is burnt battery cell case.Safety in utilization to storage battery and car load causes great threat.
In sum, reach most of rubber sleeves that car load producer uses in the market, can not satisfy increasingly mature pure electric vehicle, the safety and reliability requirement of especially high-level new-energy automobile.Need a kind of more safe and reliable protective sleeve, prevent the above-described problem from occurring.
Summary of the invention
The technical problem that the present invention will solve provides a kind of electric vehicles power lead-acid battery terminal jacket, overcomes the defective that prior art exists.
The present invention realizes through following technical scheme:
A kind of electric vehicles power lead-acid battery terminal jacket; Sheath is made up of interior cover and overcoat; Be placed in the terminal bottom in said; Between interior cover and battery container, be provided with first pad, said overcoat in it, and is connected with interior cover terminal and the copper ose bag that is connected in terminal through both set screw threads couplings.
The further improvement project of the present invention is on the mating surface of the said interior cover and first pad, to be provided with the connection groove and the convexity of mutual coupling.
The present invention further improvement project is, is provided with second pad between cover and the copper nose in said, and second pad is the annular gasket of metal material.
The present invention further improvement project is, said overcoat is made up of cover bucket and the sleeve pipe that is communicated in the cover bucket, cover bucket, sleeve pipe respectively with terminal, copper ose bag in it, it is contraction-like that cannula tip is, and the rat tail that is connected in the copper nose portion is lived.
The present invention compared with prior art has following obvious advantage:
The present invention is provided with certain thickness ring-shaped rubber pad on the bottom of interior cover and cell jar lid contact-making surface, avoided water or dirt from the battery case surface seepage on two gate terminal, form short circuit dischange, flashing burn shell.Simultaneously; Because overcoat of the present invention is made up of cover bucket and the sleeve pipe that is communicated in the cover bucket, cover bucket, sleeve pipe respectively with terminal, copper ose bag in it, cannula tip is the contraction-like rat tail that will be connected in the copper nose portion and lives; Therefore, it is isolated accumulator terminal and copper nose thereof and the external world to have been done sealing.
Terminal jacket of the present invention not only goes under the relatively poor environment like muddy, ponding of bad weather and road conditions to motor vehicle; The potential safety hazard that can effectively avoid electricity leakage due to short circuit and cause, but also can effectively avoid phenomenons such as the two poles of the earth micro short circuit of cell, the shell of burning to take place.Concerning the car load user, can avoid therefore changing battery, cause the high defective of use cost.
Description of drawings
Fig. 1 installs and uses the main TV structure sketch map (broken section) at storage battery one end for the present invention;
Fig. 2 is an overcoat enlarged diagram among Fig. 1;
Fig. 3 is the interior cover and the first pad enlarged diagram among Fig. 1.
Embodiment
As shown in Figure 1, sheath of the present invention is made up of with overcoat 2 interior cover 1.Like Fig. 1, shown in 3, said interior cover 1 is placed in terminal 3 bottoms, between interior cover 1 and battery container 4, is provided with first pad 5, on the mating surface of said interior cover 1 and first pad 5, is respectively equipped with the connection bump 11 and the groove 51 of the mutual coupling of a circle.Said first pad 5 is the ring-shaped rubber pad.Still as shown in Figure 1, between interior cover 1 and copper nose 6, be provided with second pad 7, said second pad 7 is the annular gasket of metal material.As shown in Figure 1, the interior cover 1 with second pad 7 and below thereof when bolt 8 is connected in terminal with copper nose 6 is fixed.
Like Fig. 1, shown in 2, overcoat 2 is the insulation material, and it is made up of cover bucket 21 and the sleeve pipe 22 that is communicated in the cover bucket, and cover bucket 21, sleeve pipe 22 are placed in terminal 3, copper nose 6 in it respectively, and sleeve pipe 22 ends are contraction-like, and the connecting line that is connected in copper nose 6 ends 9 bundles are lived.Said cover bucket 21 is connected with interior cover 1 coupling (overlap barrel be provided with internal thread, in be arranged with external screw thread).
