Abstract

(57) [Summary] [Purpose] To reduce the number of parts and improve workability by interposing a holder between the batteries in an assembled battery. [Structure] Safety parts are indispensable for assembled batteries, and as they were conventionally attached to the side of the battery, the safety parts had a convex shape, which caused problems with workability and when inserting the battery case. In the present invention, a holder containing a safety component is interposed between the batteries, and the terminals of the safety component are used to weld the batteries, so that the convex portion can be eliminated. By using this holder, the number of parts can be reduced and the workability can be improved.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is an assembled battery used as a power source for electronic equipment such as OA equipment, measuring instruments, and communication equipment. It is related to.

0002

[Conventional technology]

Conventionally, assembled batteries made by combining multiple batteries are equipped with thermostats and breakers. Protective elements, which are safety components, are essential. A battery pack that connects batteries in series In Japanese Utility Model Application Publication No. 55-141471, the safety section is We have proposed a battery device in which a heat-sensitive element as a product is pressed and fixed to a battery outer can.

0003 However, in this structure, as shown in Figure 4, there is a safety barrier on the external side of the assembled battery. All parts 1 themselves protrude and the outer shape of the assembled battery becomes convex, and the assembled battery is inserted into the main case. Problems occur when doing so.

0004 In addition, since the safety component 1 itself has edges, the assembled battery may be damaged by falling or vibration. There are also structural flaws such as damage and short circuits.

[0005] Further, FIG. 5 shows an exploded perspective view of a conventional assembled battery. Insert the insulating plate 3 between the batteries. Then, the lead plates 6 are welded to the battery terminals of adjacent batteries to connect the batteries in series. So Connect one terminal 2 of the safety component 1 to the terminal part of the outer battery, and connect the other end. 2' to the contact plate 4, and an insulating plate 3 between the terminals 2 and 2' of these safety components 1. ' to intervene.

[0006] A heat-shrinkable tube 8 was attached to the outer peripheral wall of the assembled battery to make a completed product. is shown in FIG. As you can see from this configuration, conventionally a large number of parts were added. It had a poorly constructed structure.

[0007]

[Problem that the idea aims to solve]

This invention solves the problems mentioned above, reduces the number of parts, and improves workability. By doing so, the aim is to simplify the processing of assembled batteries.

[0008]

[Means to solve the problem]

This invention is the same as the battery outer can for assembled batteries made by connecting multiple batteries in series. A holder having an outer diameter and having a safety component inside is provided between the batteries. It is a sign.

[0009]

[Effect]

A holder with the same outer diameter as the battery case when connecting multiple batteries in series. A protective element, which is a safety component, is stored inside the battery, and the holder is inserted between the batteries. By connecting the terminal part of the safety component to the battery terminal and insulating it with a holder, Since there is no convex part on the outside of the assembled battery, it is easier to insert the assembled battery into the main case. It becomes easy. Also, since the safety parts are inside the holder, the edges of the safety parts themselves etc. This prevents the battery from being damaged or shorted out.

0010 Furthermore, in the above configuration, the holder 5 containing the safety component 1 is interposed between the batteries, Since the batteries are electrically connected in series using terminals 2 and 2' of this safety component 1, In the past, insulating plate 3' and contact plate 4 were required to connect batteries in series using safety component 1. However, since these are no longer necessary, the number of parts can be reduced. therefore , processability is improved and costs can be reduced.

[0011]

【Example】

An embodiment of the present invention will be described based on the drawings.

0012 FIG. 1 shows an exploded perspective view of the assembled battery of the present invention. It is a protective element as safety component 1. A holder 5 containing a breaker that detects and cuts off excessive current during charging and discharging is placed between the batteries 7 and 7. It is inserted between. The structure of this holder 5 is shown in FIG. This holder 5 is It is composed of an upper surface 9 and a peripheral wall 11, and the lower surface 10 is open. this The holder 5 has a pair of recesses 12 and 13 with holes in the upper surface 9 and lower surface 10 of each other. formed side by side. That is, when the holder 5 is viewed from the side, it has a substantially S-shape with one side The bottom part 14 of the recess 12, the partition wall 16 between both recesses 12 and 13, and the bottom part 14 of the recess 12 of the other recess 13 The bottom surface 15 is integrally formed.

[0013] Further, a breaker 1 is disposed inside 17 of the holder 5, and this breaker 1 The terminals 2, 2' are provided to protrude from the pair of recesses 12, 13, respectively. There is. The protruding terminals 2, 2' are inserted into the holder through the bottom surfaces 14, 15 of the respective recesses. It is bent toward the inside of the door 5. Therefore, these terminals 2 and 2' are mutually connected. It is bent over the upper and lower surfaces of the holder 5. Connect these terminals 2 and 2' to the battery terminals. Weld to the child. In this way, the holder 5 is inserted between the batteries.

[0014] At this time, since the outer diameter of holder 5 and the outer diameter of battery 7 are the same, holder 5 should be placed between the batteries. When the batteries are inserted in the holder and connected in series, there will be no unevenness on the outside between the batteries and the holder.

[0015] Next, when connecting the battery, connect the battery terminal part with the lead plate 6, and An insulating plate 3 is interposed between the parts. Then, attach the heat-shrinkable tube 8 to the outer peripheral wall of the battery. Then, the assembled battery of the present invention is obtained.

[0016] FIG. 2 shows the external appearance of the assembled battery of the present invention made in this way. As can be seen from Figure 2 In addition, the assembled battery according to the present invention has no irregularities in appearance, so it can be inserted smoothly into the main body case. can do.

[0017] In addition, since the safety component 1 is inside the holder 5, the edge part of the safety component itself This prevents the battery from being damaged or short-circuited.

[0018] Furthermore, in the conventional configuration shown in FIG. 5, the insulating plate 3' Since there are extra parts such as the contact plate 4, the number of parts increases and the processing process becomes complicated. Become.

[0019]

[Effect of the idea]

The assembled battery of this invention has the same outer diameter as the battery outer can and has a safety device inside. Insert the provided holder between the batteries and connect the terminal part of the safety component to the battery terminal. If the assembled battery is insulated with a holder, there will be no convex parts on the outside of the assembled battery. It is also easy to insert the pond into the main body case.

[0020] Also, since the safety part is inside the holder, the safety part itself may damage the battery. This eliminates the possibility of short circuits.

[0021] Furthermore, a holder containing a safety component is interposed between the batteries, and the edge of this safety component is Since the batteries are electrically connected in series using the connector, the number of parts can be reduced. did Therefore, processability is improved and costs can be reduced, and its industrial value is extremely large.
