DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a current sensor mounting structure, and more particularly, to a current sensor mounting structure which is mounted on a battery together with a distributor.

[0002]

2. Description of the Related Art In recent years, gasoline vehicles and diesel vehicles have
Further improvement in fuel economy is required. And as one of the measures, when the battery is overcharged,
It has been considered that the alternator is disconnected from the engine and stopped to reduce the load on the engine and improve fuel efficiency. Therefore, in order to detect whether or not the battery has been overcharged, a current sensor that detects the charge / discharge state of the battery is used. This current sensor
Since the charge / discharge state of the battery is detected, it is preferable to be closer to the positive post of the battery.

[0003]

In the meantime, there is a distributor equipped with various electric devices and electronic devices mounted on a vehicle and having a built-in fuse for distributing and supplying power of a battery to these devices and devices. This distributor is generally mounted on the positive post of the battery via a battery terminal.

Therefore, when the current sensor and the distributor are mounted together with the distributor, both the current sensor and the distributor need to be mounted at a position closer to the positive post of the battery.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a current sensor capable of assembling a current sensor without taking up space for a battery on which a distributor is mounted. An object of the present invention is to provide a mounting structure.

[0006]

In order to solve the above-mentioned problems, the invention according to claim 1 is characterized in that a battery and a distributor for distributing power of a battery power source provided near the battery are provided. The point is to arrange a current sensor.

According to a second aspect of the present invention, the core of the current sensor is configured so that the battery connection terminal on the battery side of the distributor penetrates. According to a third aspect of the present invention, a distribution for distributing power of a battery power supply to a through hole formed in a sensor case main body having a core for detecting a charge / discharge current of a battery and formed to penetrate the core. A battery connection terminal for supplying a charging current to the battery extending from the container case main body is penetrated, and at least a part of the sensor case main body is overlapped with the distributor case in any one of a front view, a planar view, and a side view, and the penetration is performed. The gist is that the battery is fixed to the battery terminal of the battery with the battery connection terminal penetrating the hole.

According to a fourth aspect of the invention, in the current sensor mounting structure according to the third aspect, the battery connection terminal is connected and fixed to a bracket provided on the sensor case main body.

According to a fifth aspect of the present invention, there is provided a core for detecting a charging / discharging current of a battery in a fitting recess formed in a case body of a distributor for supplying a charging current to the battery and distributing power of a battery power supply. A battery connection terminal extending from the fitting recess is inserted into a through hole formed in the sensor case body so as to penetrate the core when fitting the sensor case body incorporating the sensor case into the fitting recess. The gist of the present invention is that the battery connection terminal is penetrated and the battery connection terminal penetrating the through hole is fixed to the battery terminal of the battery.

According to a sixth aspect of the present invention, there is provided the current sensor mounting structure according to any one of the third to fifth aspects, wherein the substrate built in the sensor case main body and the sensor case main body side wall are located outside. The gist of the invention is that the connector portion extending to the outside is arranged in a space outside the space between the connection portion formed by the battery terminal and the battery connection terminal and the distributor. (Operation) According to the first aspect of the invention, the charge / discharge current of the battery is measured by a current sensor provided between the battery and the distributor. Therefore, the current sensor can detect a current in which the charge / discharge current of the battery is not distributed by the distributor, so that the detection of the charge / discharge current of the battery can be concentrated and efficiently performed.

According to the second aspect of the invention, the charge / discharge current of the battery is measured at the battery connection terminal of the distributor that passes through the core of the current sensor. Therefore, the battery connection terminal of the distributor can also be used as the current detection terminal of the current sensor, which simplifies the structure, is advantageous in cost, and can easily detect the full charge / discharge current of the battery.

According to the third aspect of the present invention, the battery connection terminal of the distributor is made to pass through the through hole formed in the sensor case main body, and at least a part of the sensor case main body is viewed from the front, the plan, and the side. In any direction, it is overlapped with the distributor case body and connected and fixed to the positive post. Therefore, the space between the distributor case main body and the battery can be used as a space for installing the sensor case main body. Therefore, the mounting space for the sensor case main body is reduced, and the space in the engine room in which the battery is mounted can be effectively used. Furthermore, since the sensor case main body can detect the current in which the charging / discharging current of the battery is not distributed by the distributor from the battery connection terminal, the detection of the charging / discharging current of the battery can be performed efficiently with concentration. Also, since the sensor case body is connected and fixed to the distributor, it is indirectly fixed to the positive post of the battery.Therefore, the sensor case body can be mounted on the positive post without changing the shape of the positive post. The main body can be easily assembled to the battery.

According to the fourth aspect of the present invention, the battery connection terminal is fixed to the battery terminal while being connected and fixed to the bracket provided on the sensor case main body. Therefore, the distributor and the sensor case main body are firmly fixed.

According to the fifth aspect of the present invention, since the sensor case main body is fitted and fixed in the fitting recess formed in the distributor case main body, the distributor case main body becomes larger by the size of the sensor case main body. At this time, an empty space in the height direction around the battery, which is generated when the distributor case body is fixed to the positive post of the battery, can be used as a space for fitting and fixing the sensor case body. Therefore, it is possible to reduce the planar mounting space of the sensor case main body and effectively use the space in the engine room in which the battery is installed. Furthermore, since the charge / discharge current of the battery is detected by the sensor case main body at the battery connection terminal that is not distributed by the distributor, the detection of the total charge / discharge current of the battery can be efficiently performed at one location. Further, since the sensor case main body is fitted and fixed to the distributor case main body and is not fixed to the positive post of the battery, the sensor case main body can be easily assembled to the battery without changing the shape of the positive post.

According to the present invention, in a state where the battery connection terminal is passed through the through hole of the current sensor,
When the battery connection terminal is fixed to the battery terminal, the substrate and the connector of the current sensor are disposed outside the space between the connection between the battery terminal and the battery connection terminal and the distributor. Therefore, when the distributor and the sensor case main body are fixed to the positive post of the battery, the board and the connector do not become obstacles, and the distance between the distributor, the sensor case main body, and the battery can be reduced, and the current sensor mounting structure. The whole can be reduced in size. In other words, the board and the connector, which are portions thicker than the core portion of the current sensor, are not arranged between the battery terminal and the connection portion between the battery connection terminals. Therefore, the current sensor can be mounted between the battery and the distributor by increasing the space between the battery and the distributor by the thickness of the core portion of the current sensor.
