Description

[Detailed description of the invention] [Industrial field of application] This invention is a battery connection device that is used by connecting to a battery installed inside the engine compartment of an automobile. The present invention relates to a battery connecting device that can increase the capacity of a battery by connecting another battery to the battery when the battery is low.

[Conventional technology]

Battery capacity decreases under low temperature conditions due to factors such as an increase in internal resistance and a delay in ion replenishment, and the amount of decrease is particularly significant at temperatures below 0°C. For this reason, for example, in the case of batteries used in automobiles, etc., if the automobile is left in a cold region for a long period of time, the capacity of the battery will decrease, and the starter will not operate due to so-called battery build-up, causing the engine to start running. may not be able to start.

Therefore, a cable a as shown in FIG. 3 has been developed so that the battery capacity can be increased by charging the battery using, for example, the battery of another vehicle. That is, this cable a has alligator-shaped connecting means b attached to both ends, and a pair of such cables a is used to connect the respective terminals of both batteries c and d, as shown in Fig. 4. It's becoming like that.

[Problem to be solved]

However, in the case of such cables, each terminal of the battery does not protrude very long, so when using the terminals to make an electrical connection, the connecting means easily comes off from the terminals, which poses a problem. .

Further, unless such a cable is always kept in the car, it cannot be used in an emergency such as when battery trouble occurs at a travel destination.

Furthermore, if, for example, the engine stalls again after being charged using this cable, the amount of charge will be insufficient and the same operation will have to be repeated again. It's a hassle.

Therefore, in view of the above-mentioned drawbacks of the conventional battery, this invention allows you to connect another battery easily and reliably whenever necessary, and also allows you to drive by installing an additional battery in advance. However, it is an object of the present invention to provide a battery connecting device that can also be charged using the battery.

[Means for solving problems]

In the battery connection device of this invention, after removing the main terminal of the main cord for connecting the main battery and the engine side from the terminal of the main battery that is pre-equipped in the car, connect the terminal to another separately prepared one. A battery connection device that connects an additional battery to charge the main battery and connects the main terminal to the terminal side, and is provided with a cord and at both ends of the cord, and connects the main battery and the additional battery. An approximately ring-shaped conductive additional terminal that tightens and fixes the terminals of the same polarity as the battery, and the main terminal of the main cord that has the same shape as the terminal of the main battery and that has been removed from the terminal is attached. Further, a pair of connecting bodies each having a conductive additional terminal provided on one of the additional terminals is provided.

[Effect]

The battery connection device of this invention first removes the terminal at the end of the cord that was connected to the battery to supply power to the engine, etc. Attach the roughly ring-shaped additional terminal on one end of the cord of the connection body to the terminal, securely fixing it, and then attach the first cord removed to the additional terminal provided on the attached additional terminal. Securely attach this terminal so that it does not come off at all times. If you do this, power can normally be supplied from the main battery to the main battery terminal -> additional terminal of the connection body -> additional terminal of the connection body -> main terminal -> main cord -> engine, etc. In addition, when the capacity of the main battery decreases, you can prepare an additional battery and connect the approximately ring-shaped additional terminal on the other end of the cord of this connection body to the terminal of the additional battery. It is now possible to easily connect both batteries at any time.In other words, as long as you have another charged battery available, you can easily connect the batteries to each other at any time for charging in an emergency. It is something that can be done.

〔Example〕

An embodiment of this invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a battery connection device according to this invention, and this battery connection device has a configuration including a pair of connection bodies 4 having a cord 1, an additional terminal 2, and an additional terminal 3. There is.

The cord 1 is used to connect in parallel with another additional battery 5 to energize the additional battery 5 and the original main battery 6 installed in the car when necessary. It uses large steel wire, etc., and is coated with insulating rubber on the outside.

The additional terminal 2 is for connecting the terminals of the same polarity of the main battery 6 and the additional battery 5, and is approximately U-shaped (ring-shaped) with a tightening bolt 2a on the tip side. Attached to both ends of cord 1. The additional terminal 2 on one side is always fixed to each terminal 6a on the main battery 6 side so as not to be removed.
Further, the additional terminal 2 on the other end side is, for example, a second
As shown in the figure, except when connecting to each terminal 5a of the additional battery 5 in an emergency such as when battery trouble occurs, each terminal is covered with an insulating rubber body (not shown), and each terminal is left in this state. Connection body 4
It has come to be kept stored in the engine room of a car at all times.

As shown in FIG. 2, the additional terminal 3 is provided integrally with the additional terminal 2 on one side in order to electrically connect the main battery 6 to the engine 7 side of the automobile. That is, this additional terminal 3 is always connected to the main terminal 9 attached to the end of the main cord 8 installed in advance in the engine room, and this main terminal 9 can be easily and easily connected. The terminal 6a of the battery 6 has a cylindrical shape so that it can be reliably fitted or tightened.
It has a cylindrical shape with the same diameter.

Therefore, according to the battery connection device according to this embodiment, when the capacity of the main battery 6 decreases due to a drop in temperature, for example, and the engine does not start, an additional battery is connected to each terminal 5a of the additional battery 5 prepared elsewhere. By simply setting the terminal 2 and tightening the screw 2a, the batteries 6 can be reliably connected and the battery 6 can be charged.

Note that this battery connection device is designed not only to be connected to the additional battery 5 for charging as explained earlier, but also to be connected to the main battery 6 on a regular basis. Although it is necessary to connect the battery connecting device and the main battery 6 in advance, this can be done in the following procedure.

First, the main terminal 9 at one end of the main cord 8 connected to each terminal 6a of the main battery 6 is removed from the terminal 6a.

Next, the additional terminals 2 of the connecting body 4 are securely attached and fixed to each terminal 6a of the main battery 6 from which the main terminal 9 has been removed.

Next, the removed main terminal 9 is securely attached and fixed to the additional terminal 3 provided on the additional terminal 2 side fixed to each terminal 6a side of the main battery 6.

As described above, the connection body 4 may be kept connected to the main battery 6 at all times.
