Description

[Detailed description of the invention] <Industrial application field> This invention relates to a battery with a lead body, and more specifically, in a battery with a lead body for mounting on a so-called board, in which a lead body for taking out current is attached to a battery terminal. It relates to devices designed to improve workability during installation.

<Conventional technology> With the recent spread of electronic devices,
Batteries with lead bodies as described above have come to be widely used as power supplies for IC memory backups and the like. This type of leaded battery is coin-shaped,
It is constructed by electrically connecting and fixing one end of a linear or plate-shaped metal lead to the terminal surface of a cylindrical battery, etc. by spot welding, etc., to ensure stable operation over a long period of time. Therefore, the other end of the lead body is often inserted into a hole in a printed circuit board, etc., and then directly attached by soldering.

<Problems to be solved by the invention> By the way, when soldering a battery with leads to a board, so-called flow soldering, which is generally used for automatic soldering of capacitors, resistors, etc., is a process in which the battery is shot externally. It is unusable because it breaks, and is usually done by hand. In this case, the operator holds the battery with the lead body in one hand, with the other end of the lead body passed through the board hole, and uses the soldering iron held in the other hand to solder the lead body end protruding to the back side of the board on the back side. Methods such as doing this are taken. However, the board hole is slightly larger in size than the lead body in order to improve the workability of inserting the lead body and to accommodate pitch variations between the lead bodies, and there is some clearance between the board hole and the lead body. This clearance makes it difficult to position the lead body within the substrate hole. In addition, it becomes difficult to solder in the correct position, leading to many installation defects such as tilting of the lead body and uneven battery installation height, which requires resoldering many times to correct them. There is. For this reason, there is a problem that the board mounting work takes time and workability is poor. In order to eliminate this problem, a lead body may be inserted into the hole in the board until the outer surface of the battery and the surface of the board come into contact with each other and then soldered. It cannot be applied to cases where thermal effects are to be minimized.

<Means for solving the problem> The battery with a lead body of this invention is a battery with a lead body having a battery 1 and lead bodies 2, 3, 5, 6, 7, 8 for taking out current, One end of the lead body is electrically connected to the terminals 1a, 1b of the battery, and stoppers 2a, 3a, 5a, 6a, 7 are provided at a predetermined distance from the battery.
a, 8a are provided, and the stopper portion is connected to the substrate 4 around the substrate holes 4a, 4b into which the lead body is inserted.
The gist of this is that it can be locked in place.

The stoppers can be provided by forming folded parts or protrusions at appropriate locations if the lead body is a plate-shaped body, or by crushing the appropriate areas to form plate-shaped parts if the lead body is a linear body. Use.

<Function> By providing the stopper part as described above, when the lead body is inserted into the board hole, the stopper part contacts and locks the board around the board hole, and the battery is removed from the board surface. The distance to the lead body is kept constant, allowing easy and always correct positioning of the lead body.

<Example> In the example shown in FIG. 1, one end of the lead plates 2 and 3 are spot-welded to the positive terminal 1a and negative terminal 1b of the coin-shaped battery 1, respectively, at the "x" part in the figure. installed. Lead plate 2,
At a position equidistant from the battery 1 in No. 3 (more specifically, at an equidistant position from the battery center line perpendicular to the extending direction of the lead plates 2 and 3), the cross section is V-shaped and one side is convex. The folded portions 2a and 3a are each formed by press molding or the like. In this case, by making the convex side of the folded parts 2a, 3a opposite to the surface facing the lead plate as shown in FIG. The contact that causes shoots can be made as small as possible, and the present invention can also be applied to a format using an ultra-thin coin-type battery.
Figure 2 shows lead plates 2 and 3 of this battery with lead bodies.
This figure shows the state in which the other end is inserted into the board holes 4a, 4b of the board 4, and the folded parts 2a, 3a, which are stopper parts, are locked by the board holes 4a, 4b.
In this way, the positioning of the lead-equipped battery can be easily and correctly performed.

As a stopper part provided at the other end of the lead plate for positioning the lead plate on the board, for example, the stopper part provided on the lead plates 5 and 6 shown in FIG. The protrusions 5a and 6a may be formed by pressing only the hemispherical portions. In this case, as in the case of the embodiment shown in FIG. 1, it is preferable to set the surface on which the protrusions 5a and 6a are formed on the side opposite to the surface facing the lead plate in order to prevent battery external shoots.

In addition, if the lead body is a wire material, the third
As shown in FIG. B, plate-like portions 7a and 8a may be formed by press molding or the like at predetermined positions on the other ends of the lead wires 7 and 8, one end of which is spot welded to the battery terminal, respectively. Such plate-like portions 7a, 8a may be formed in advance on the lead wires 7, 8 before spot welding, or may be formed by press-molding the lead wires 7, 8 together after spot welding. . still,
It goes without saying that the lead wire may be one in which one end to be spot-welded to the battery terminal is previously formed on a plate by press molding or the like.

<Effect of the invention> The battery with lead bodies such as the lead bodies 2, 3, 5, 6 and the lead wires 7, 8 of this invention has the above-mentioned folded parts 2a, 3a, protrusions 5a, 6a,
This device is provided with stopper parts such as plate-shaped parts 7a and 8a, and when inserting the lead body into the board, the stopper part is securely locked by the board hole, eliminating variations in the position and tilt of the battery, and ensuring that the board shape does not change. Since the lead body can be easily and always correctly positioned, there is no need for time-consuming positioning or correction work as in the past, and it has the effect of improving the workability of mounting a battery with a lead body on a board. It has industrial utility value in that it is effective for types that use small batteries that are difficult to use.
