Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model and beneficial effect thereof are described in more detail, but embodiment of the present utility model is not limited to this.
Refer to Fig. 1 to Fig. 6, the electrode protection structure of a kind of battery pack that the present embodiment provides, comprises electrode 2 and electrode sheath 1, electrode 2 comprise insertion section 21, extension 22 and be connected in insertion section 21 and extension 22 between connecting portion 23; Wherein, extension 22 is installed in battery pack, and for being electrically connected to the negative or positive electrode on battery, insertion section 21 is in electrode insertion sheath 1, and 23 of connecting portions are in order to realize the connection between insertion section 21 and extension 22; Electrode 2 is for realizing the output of battery pack current.
Electrode sheath 1 comprises sheath body 11 and is arranged at the interior jack 12 for accommodating insertion section 21 of sheath body 11; Electrode sheath 1 adopts Shooting Technique to produce, and cost low weight is light.
The both sides of the close connecting portion 23 of insertion section 21 are provided with back taper projection 24, and the wider bottom surface of back taper projection 24 arranges near connecting portion 23.That is to say, from insertion section, 21 insertion end looks over to its link (i.e. one end of close connecting portion 23), and the projection of back taper projection 24 on its insertion end place end face increases gradually.The setting of back taper projection 24 is in order to realize the secure fit of electrode 2 and electrode sheath 1, prevents that electrode 2 from use shaking and the problem on fire that causes, improves the security performance of battery pack.
The thickness of the height of jack 12 and insertion section 21 matches, thereby has solved the installation orientation problem of electrode 2 in electrode sheath 1, avoids the problem of the difficult contraposition of external high pressure joint that electrode 2 deflections cause, and is conducive to the assembling of external high pressure joint.
Wherein, as shown in Figure 6, the shape of back taper projection 24 is set to Mitsubishi's cylindricality, and this Mitsubishi's cylindricality is not positive Mitsubishi cylindricality, on the triangle end face of Gai Mitsubishi cylindricality, is less than the length of side on other two limits near the length of side on that limit of connecting portion 23.
The both sides of the close connecting portion 23 of concrete insertion section 21 are provided with two back taper projections 24, and be arranged in two back taper projections 24 of the same side of insertion section 21, the width of the bottom surface of the back taper projection 24 of more close connecting portion 23 is greater than the width of the bottom surface of another back taper projection 24.Because when insertion section 21 is inserted in jack 12, the position of the back taper projection 24 of more close connecting portion 23 is for the position of another back taper projection 24, the end of more close jack 12, therefore, this structure can little by little be securely fixed in electrode 2 in jack 12, guarantees that electrode 1 in use firmly coordinates with electrode sheath 2.
The both sides of the join domain of connecting portion 23 and insertion section 21 are provided with block 25, and block 25 inserts the degree of depth of jack 12 for limiting the insertion section 21 of electrode 2, and after having assembled, this block 25 is arranged at outside jack 12.
The bight of one end away from connecting portion 23 of insertion section 21 is set to circular arc, and rounding processing has been carried out in one end away from connecting portion 23 of insertion section 21, to realize electrode 2, coordinates with the guiding of the jack 12 of electrode sheath 1, and convenient production assembled.
The both sides of connecting portion 23 are provided with notch 26, and the notch 26 of both sides is all set to two, general, the width of extension 22 is greater than the width of insertion section 21, therefore, arranging of notch 26 can be guaranteed the control to flash in bending technique, makes electrode 2 in assembling process, avoid assembly problem and the impact on spare part outside measurement being caused by flash.
Sheath body 11 comprises integrated electrode connecting portion 111 and external high pressure joint connecting portion 112, and jack 12 is arranged in electrode connecting portion 111.
The both sides of electrode connecting portion 111 are provided with the first buckle 113 and positioning bar 114, and one end of electrode connecting portion 111 is also provided with reinforcement 115, and reinforcement 115 is positioned at the top of jack 12.The positioning bar 114 of electrode sheath 1 is for realizing the guide-localization of electrode sheath 1 on other part, the adjustment of the mutual alignment of two positioning bars 114 and two the first buckles 113 simultaneously can realize foolproof function, for for connecting the electrode protection structure of positive pole and the negative pole of battery, only need to be by position and the size of two positioning bars 114 and two the first buckles 113 be simply set, just can realize the fool proof of both positive and negative polarity: for connecting the anodal electrode protection structure of battery, can only be connected with the positive pole of battery, and can not be connected with the negative pole of battery; Vice versa.Reinforcement 115 can be guaranteed the structural strength of jack 12 in the process coordinating with electrode 2.
One side of external high pressure joint connecting portion 112 is provided with the second buckle 116 and square groove 117, and one end of external high pressure joint connecting portion 112 is also extended with mounting panel 13, and the protrude end of mounting panel 13 is provided with the 3rd buckle 131.The first buckle 113 and the second buckle 116 can be realized the fixing of electrode sheath 1.The 3rd buckle 131 the problem that electrode sheath 2 upwarps at installation process middle front part that solved is set.
The inside of external high pressure joint connecting portion 112 is provided with limiting plate 118, between limiting plate 118 and the base plate of external high pressure joint connecting portion 112, is provided with support bar 119.Limiting plate 118, for the protection of the external high pressure joint realizing electrode 2 and be electrically connected to this electrode 2, prevents that electrode 2 and external high pressure joint are outside exposed, reaches the object of high voltage protection, prevents that user from getting an electric shock, and its degree of protection can reach IPXXB level.If support without 119 pairs of limiting plates 118 of support bar, limiting plate 118 easily deforms, and is unfavorable for the realization of high voltage protection object.Meanwhile, limiting plate 118 also can be realized electrode 2 and coordinate with the guiding of external high pressure joint, to realize the conducting of electric current.The square groove 117 of electrode sheath 1 can be realized the snap-fitted of this electrode protection structure and external high pressure joint.
In a word, the utility model is simple and compact for structure, is easy to assembling, easily realizes mass production, can effectively realize the protection of electrode 2 with fixing.
The announcement of book and elaboration according to the above description, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should be in the protection range of claim of the present utility model to equivalent modifications more of the present utility model and change.In addition,, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
