Description

  The present invention relates to a battery pack in which a battery core of a rectangular battery is arranged inside a frame case in which plastic is molded into a frame shape to form a battery assembly, and an exterior label is attached to the battery assembly. The present invention relates to a battery pack divided into two and connected to each other.

  A battery pack has been developed in which the outer periphery of a battery core of a rectangular battery is covered with a frame case, and an exterior label is attached to the surface. (See Patent Document 1)

An exploded perspective view of the battery pack of Patent Document 1 is shown in FIG. This battery pack is assembled as follows.
(1) A circuit board 91 having an output terminal 85 is connected to the rectangular battery 81 to form a battery core 82.
(2) The battery core 82 is connected to a first frame case 83A in which plastic is molded in a U shape.
(3) The U-shaped second frame case 83B is connected to the first frame case 83A to form a battery assembly 92.
(4) The exterior label 84 is attached to the surface of the battery assembly 92.

  The battery pack assembled by the above method needs to connect the second frame case 83B to the first frame case 83A in a determined posture. This is because the second frame case 83B is formed with an asymmetric shape on the front and back. The asymmetric second frame case 83B on the front and back can be provided with a knob 90 for taking out the battery pack from the electric device on one side, and the shape of the battery core 82 can be asymmetric on the front and back. The second frame case 83B having an asymmetric shape on the front and back can be connected to the first frame case 83A in a posture determined by providing a reverse insertion prevention marking 93 on the surface of the connection frame 87. This is because the assembling operator can confirm the reverse insertion prevention marking 93 and connect the second frame case 83B to the first frame case 83A. The reverse insertion prevention marking 93 can be provided on the surface of the connection frame 87 in a concave / convex display as shown in FIG. 1 in the step of molding the plastic second frame case 83B. However, the reverse insertion prevention marking provided in the molding process is difficult to see and difficult to confirm accurately, and has the negative effect of erroneously connecting the second frame case in the reverse direction in the manufacturing process.

  This drawback can be eliminated by forming the connecting frames on both sides of the first and second frame cases into different lengths. However, it is not preferable that the connecting frames of the frame case have different lengths for the following reason. The first reason is to make the elongated connecting frame 87 thin with plastic in order to make the outer shape of the battery pack as compact as possible, and the second reason is that the rectangular battery 81 is attached to the first frame case 83A. The lead plate 94 is spot-welded and connected to the rectangular battery 81 in the inserted state, and the third reason is to form the tip of the connecting frame 87 thinly from the draft angle of the mold. That is, in order to connect the lead plate to the prismatic battery with the square battery inserted in the first frame case, the lead plate can be spot welded to the prismatic battery 1 with the prismatic battery inserted in the first frame case. There is a need to. For this reason, it is necessary to shorten the connection frame of the first frame case and lengthen the connection frame of the second frame case. Further, since the connecting frame is formed thin, it is necessary to lengthen one connecting frame in order to make the connecting frames at both ends different in length, and the tip of the long connecting frame becomes extremely thin, making it difficult to form. For this reason, the 2nd frame case which shape | molds the connection frame of both sides in the same length can mass-produce efficiently, without the front-end | tip of one connection frame becoming very thin.

In addition, as shown in FIG. 1, it is considered that the front ends of the first frame case and the second frame case can be prevented from being reversely connected as shown in FIG. Cannot prevent reverse connection of the frame case. This is because the tip of the connecting frame is extremely thin, so that it can be connected in the opposite direction in practice. Further, in the battery pack of FIG. 1, the connection frame 87 of the first frame case 83A and the second frame case 83B is ultrasonically welded to firmly connect the frame case 83. There was a drawback that it took time to connect.
