A positive electrode terminal insertion space 113 is formed between the positive electrode terminal insertion partition wall 111 and the first outer wall 112 to receive the positive electrode terminal 123 therein.

On the plate surface of the positive electrode terminal insertion partition wall 111, an electrode exposing hole 115 is formed through a certain length. The electrode exposing hole 115 exposes the contact protrusion 123b of the positive electrode terminal 123 to the outside of the positive electrode terminal inserting partition wall 111 as shown in FIG. Whereby the contact protrusion 123b comes into contact with the anode (a) of the battery (A). The negative electrode terminal insertion partition wall 117 contacts and supports the negative electrode terminal 133.

A battery A is accommodated in a space between the positive electrode terminal insertion partition wall 111 and the negative electrode terminal insertion partition wall 117.

A wire connecting rib 121a extending upward in a predetermined length is provided at an upper portion of the anode wire connecting plate 121. The wire connecting rib 121a is formed to protrude from the upper portion of the battery box 100 when the anode wire connecting plate 121 is inserted into the anode terminal inserting space 113. [ Thus, the user can easily connect the positive electrode wire 160 to the externally projected wire connecting rib 121a. A plurality of wire connecting holes 121b and 121c are formed on the surface of the wire connecting rib 121a.

3B is an exemplary view illustrating a process of connecting the positive electrode wire 160 to the positive electrode wire connecting plate 121. FIG. As shown in the figure, the user inserts the front end portion 161, from which the coating of the anode cable 160 is removed, into the lower electric wire connecting hole 121b and discharges it to the upper electric wire connecting hole 121c, 160 and the anode wire connecting plate 121 can be completed.

The positive electrode terminal 123 is inserted into the positive electrode terminal insertion space 113 so as to be in electrical contact with the positive electrode wire connection plate 121. The anode terminal 123 is formed of a plate-like material of a conductive metal. A contact protrusion 123b protruding toward the anode (a) is formed on the surface of the anode terminal 123. The upper end of the positive electrode terminal 123 is provided with a latching protrusion 123a which is vertically bent and is fixed to the positive electrode terminal insertion partition wall 111. [ On both sides of the positive electrode terminal 123, a support vane 123c cut toward the positive electrode terminal insertion partition wall 111 is provided. The support vane 123c is elastically supported on the positive electrode terminal insertion partition wall 111 and supports the position when the positive electrode terminal 123 contacts the positive electrode a.

[ The negative electrode connection part 130 includes a negative electrode wire connecting plate 131 connected to the negative electrode wire 170 and a negative electrode terminal 133 contacting the negative electrode b of the battery A. [

The negative electrode wire connecting plate 131 has the same configuration as the positive electrode wire connecting plate 121.

The negative electrode terminal 133 is disposed so as to surround the negative electrode terminal inserting partition wall 117. The negative electrode terminal 133 includes a vertical plate 133a inserted into the negative terminal insertion space 118, a connecting plate 133b disposed on the upper portion of the vertical plate 133a, b) of the elastic plate 133c.

The vertical plate 133a is inserted into the negative terminal insertion barrier wall 117 and is in contact with the negative electrode wire connecting plate 131. The connection plate 133b is mounted on the upper surface of the negative terminal insertion barrier wall 117. The elastic plate 133c extends from the connecting plate 133b and is in contact with the cathode (b). The elastic plate 133c is elastically moved with respect to the connecting plate 133b and contacts the cathode b when the battery A is inserted.

The serial connection unit 140 allows the position of the plurality of battery boxes 100 to be physically fixed when they are connected in series. The serial connection units 140 are implemented by being fitted to each other in a concavo-convex manner. The serial connection unit 140 includes a serial connection protrusion 141 protruded from the first outer wall 112 and a serial protrusion insertion groove 143 formed through the second outer wall 119.

The series coupling protrusions 141 are formed to have a predetermined length along the height direction of the first outer wall 112. Here, the series coupling protrusions 141 are formed in such a shape that the sectional shape gradually becomes wider toward the outer side like an inverted triangle or a trapezoid.

And the serpentine insertion groove 143 is formed in the second outer wall 119 in an incision. The series-protrusion insertion groove 143 is formed to correspond to the cross-sectional shape of the series-coupling projection 141. Since the cross-sectional shape of the series coupling protrusion 141 is formed so as to be wider as it goes outward, when the series coupling protrusion 141 is inserted into the series convex insertion groove 143, no force is applied in the vertical direction, When the force is applied in the horizontal direction, the series coupling projections 141 are not separated from the series projection insertion grooves 143. [

Therefore, structural stability can be assured when a plurality of battery boxes 100 are coupled in series.

The parallel connection part 150 is provided on both side walls of the box body 110 so that the position of the parallel connection part 150 is physically constrained when the plurality of the battery boxes 100 are connected in parallel. The parallel connection part 150 includes a side coupling protrusion 151 provided on one side wall and a side projection insertion groove 153 provided on the other side wall corresponding to the position of the side coupling protrusion 151.

The side surface coupling protrusions 151 and the side surface projection insertion grooves 153 are provided on the side wall of the box body 110 in a direction facing each other.

The shape of the side coupling protrusions 151 is the same as that of the series coupling protrusions 141. The side projection insertion grooves 153 are provided between the groove support pillars 155 spaced apart from each other.
