Rainwater etc., which enters from the joint of conductive nut 3 and shell 7 inside battery pack, damages battery pack.
Therefore the utility model embodiment does not have to consideration battery pack installation using 7 battery pack of plastic casing of 48V
After, shell 7 charge the problem of.Tradition generally uses the form of high-voltage connector, but high pressure with the mode of external electrical connections
The form of connector is unsuitable for 7 battery pack of plastic casing of 48V, therefore, using the connecting terminal 100 of the utility model embodiment
Be more suitable for 7 battery pack of plastic casing of 48V, not only assembly is simple, and manufacturing cost is low, and can make the leakproofness of battery pack compared with
More preferably.
According to the connecting terminal 100 for battery pack of the utility model embodiment, which not only assembles letter
Single, manufacturing cost is low, and the leakproofness of battery pack can be made more preferable, and is more suitable for 7 battery pack of plastic casing of 48V.
As shown in figs 2-4, the head flange around bar portion 12 is provided on the side being connected with bar portion 12 on head 11
111.Specifically, head flange 111 and 11 concentric of head, and the cross-sectional area of head flange 111 is less than the transversal of head 11
Area.
Preferably, head 11 and head flange 111 be suitable for it is integrally formed together, the overall structure of screw rod can be made as a result,
It is more compact, intensity bigger.
Further, internal connection row 2 includes：It is socketed ring 21, socket ring 21 is set in head flange 111, and is socketed ring
21 are folded between conductive nut 3 and head 11.Socket ring 21 is fastenedly connected with head 11 and conductive nut 3, and then will
Screw rod and conductive nut 3 are passed in fax from battery modules, form electrical connection.
Further, with reference to Fig. 4, the endoporus of socket ring 21 is oblong hole 211, the shape of head flange 111 with it is oval
Shape hole 211 is adapted to hinder socket 21 opposing headers flange 111 of ring rotation, after in battery pack, installation is complete as a result, convenient for outer
Portion's connection row 8 is fastened in bar portion 12 and conductive nut 3, avoids when clamp nut 9 is tightened in installation, screw rod rotates
Hinder the installation of clamp nut 9.
As shown in Fig. 2, the thickness of socket ring 21 be more than the thickness of head flange 111 and be socketed ring 21 towards conductive nut
Head flange 111 is protruded in 3 side, to be formed between socket ring 21 and head flange 111 for installing the second sealing ring 5
Recess portion 6.
Further, the side of the direction socket ring 21 of conductive nut 3 is provided with lower deep gouge 31, lower deep gouge 31 and 6 edge of recess portion
A part for the axial face of bar portion 12, the second sealing ring 5 is located in lower deep gouge 31 and another part is located in recess portion 6, as a result,
The sealing effect that connecting terminal 100 can be greatly increased avoids rainwater etc. from entering battery from the joint of bar portion 12 and conductive nut 3
In packet, therefore, the second sealing ring 5 is arranged between lower deep gouge 31 and recess portion 6 can play good sealing function.
In conjunction with Fig. 2 and embodiment illustrated in fig. 4, conductive nut 3 is formed with deep gouge 32 on the side of socket ring 21,
Upper deep gouge 32 is for installing the first sealing ring 4.Deep gouge 32 can be such that the first sealing ring 4 is limited in deep gouge 32 in setting, be convenient for
The installation of first sealing ring 4 is fixed, and is avoided after in battery pack, installation is complete, the first sealing ring 4 is folded in shell 7 and conductive nut
When between 3, the first sealing ring 4 deviates conductive nut 3 due to pressing force, and sealing effect is made to be deteriorated.
As Figure 1-Figure 4, the inside of upper deep gouge 32 is the upper deep gouge internal perisporium 321 of annular and outside is the upper heavy of annular
Slot periphery wall 322, at least part of upper deep gouge internal perisporium 321 are pierced by shell 7 and are suitable for connecting external connection row 8, as a result, with
External connection row 8 is electrically connected, and then will be outside the power transmission to battery pack of battery pack.
Further, the thickness of upper deep gouge internal perisporium 321 is more than the thickness of upper deep gouge periphery wall 322.Upper deep gouge internal perisporium 321
The wall being threadedly coupled with bar portion 12, therefore, manufacture it is relatively thick, need deep gouge internal perisporium 321 to bear larger
Twisting resistance, avoids that there is a phenomenon where 3 bendings of conductive nut.
Further, the size of axial direction of the upper deep gouge internal perisporium 321 along bar portion 12 is more than upper 322 edge of deep gouge periphery wall
Axial size.Hereby it is achieved that after in battery pack, installation is complete, a part for the upper deep gouge internal perisporium 321 of conductive nut 3 is prominent
Go out shell 7 and is electrically connected with external connection row 8.
