Description

  The present invention relates to a battery terminal with a current sensor in which a current sensor is assembled to a battery terminal, and more specifically, the battery terminal is connected to a battery post of a battery having a first side and a second side with different distances from the battery post. The present invention relates to a battery terminal with a current sensor.

  In recent years, the number of electrical components has increased as the functionality of automobiles has increased. It is known that an increase in electrical components will severely consume the on-board battery.

  Conventionally, a current sensor is provided at a battery terminal connected to a battery post of a battery or a terminal of a cable terminal connected to the battery terminal (see, for example, Patent Document 1 below).

  In connecting the battery terminal to the battery post, first, the battery terminal is moved downward, and the battery post insertion hole formed in the battery terminal is brought into contact with the peripheral side surface of the battery post. Next, the direction of the battery terminal is arranged in accordance with a predetermined direction. Next, tighten the bolts and nuts using a tool such as an impact wrench from the side of the battery terminal. As a result, the battery post insertion hole is contracted in the diameter reducing direction, and the battery post insertion hole is brought into pressure contact with the peripheral side surface of the battery post, thereby completing the attachment of the battery terminal.

  In the above prior art, when connecting to the battery post, the orientation of the battery terminal is aligned with a predetermined direction. After this, the battery terminal is centered on the battery post when tightening with a tool. Rotation and orientation (arrangement) may change (or the battery terminal may rotate when the terminal of the cable terminal is connected to the battery terminal, and the orientation may change). Therefore, since work for reorienting is required, there is a problem that workability is affected. Therefore, the inventor of the present application tried to prevent rotation of the battery terminal by providing a rotation stopper, but it was found that simply providing a rotation stopper could not cope with it.

  Specifically, the battery has side surfaces with different distances from the battery post, that is, a first side surface and a second side surface. If an attempt is made to connect a battery terminal to the battery post of such a battery, the battery terminal is temporarily connected. In the connection when the extending direction of the battery is directed to the first side, the rotation of the battery terminal can be prevented by a detent, but the connection is performed when the extending direction of the battery terminal is directed to the second side. In that case, it was found that there was too much space between the second side and it was not possible to respond.

  The inventor of the present application considers that there is room for examination because the extending direction of the battery terminal in the connection work to the battery post differs depending on the type of the battery, or differs depending on the vehicle type, grade, and the like.

The current sensor 5 is a bolt-integrated type in this embodiment. The current sensor 5 is the same as the first and second embodiments except for the rotation preventing means 61.

  12 to 16, the detent means 61 is provided in the current sensor 5. The detent means 61 is provided as a detent for the battery terminal 4 with the battery post 3 as the center. The anti-rotation means 61 can be brought into contact with the first side surface 8 in a state where the battery terminal 1 with current sensor extends to the first side surface 8 side, and the battery with current sensor on the second side surface 9 side. The terminal 1 is configured to be able to come into contact with the second side surface 9 in an extended state. Hereinafter, a specific description will be given.

  The anti-rotation means 61 in this embodiment is made of resin and has a mounting portion 62 provided on the sensor block 19 of the current sensor 5 and a selectable first anti-rotation device that is detachably mounted on the mounting portion 62. A mounting part 63 and a second anti-rotation mounting part 64 are included.

  The mounting portion 62 is arranged and formed according to the distance from the battery post 3 to the first side surface 8. The mounting portion 62 includes a side surface mounting portion 45 formed on each of the side surfaces 27 and 28 of the sensor block 19 and a hole-shaped mounting portion 46 formed in the sensor block 19 so as to penetrate in the vertical direction. (The configuration is an example.) The side surface mounting part 45 and the hole-shaped mounting part 46 are formed in the same manner as in the second embodiment.

  The first anti-rotation mounting component 63 is the same as the anti-rotation mounting component 44 (see FIG. 9) of the second embodiment, and includes an arm portion 49, a support column portion 50, and an anti-rotation portion 51. ing. The first anti-rotation mounting part 63 is provided so that the anti-rotation part 51 faces the first side surface 8 with a slight gap and when the rotation around the battery post 3 occurs. Is formed in contact with the first side surface 8.

  The second anti-rotation mounting component 64 is the same as the first anti-rotation mounting component 63 in which the anti-rotation portion 51 is changed, and is connected to the arm portion 49, the support column portion 50, and the anti-rotation portion 65. Part 66. A pair of anti-rotation portions 65 are provided at a predetermined interval, and are coupled to the arm portion 49 via a connecting portion 66. The anti-rotation portion 65 is formed in a substantially bar shape that extends by the difference between the distance from the battery post 3 to the first side surface 8 and the distance from the second side surface 9. The anti-rotation portion 65 has a substantially rod-shaped end surface facing the second side surface 9 with a slight gap, and when the rotation around the battery post 3 occurs. It is formed so as to contact the second side surface 9.

  Next, the connection of the battery terminal 1 with a current sensor to the battery post 3 will be described based on the above configuration and structure. FIG. 17 is a perspective view of connection when the extending direction of the battery terminal 1 with current sensor is the first side surface 8 side, and FIG. 18 is the perspective view of the extending direction of the battery terminal 1 with current sensor on the second side surface 9 side. FIG. Reference is also made to FIG. It is assumed that the battery terminal 1 with a current sensor is in a state in which the first detent mounting component 63 or the second detent mounting component 64 is mounted in advance.

  For connection to the battery post 3, first, the battery terminal 1 with a current sensor is moved downward to bring the battery post insertion hole 16 into contact with the peripheral side surface of the battery post 3. Next, the direction of the battery terminal 1 with a current sensor is arranged according to a predetermined direction. At this time, due to the presence of the rotation preventing means 61, the arrangement can be easily performed. Subsequently, the nut 15 is tightened from the lateral direction of the battery terminal 1 with the current sensor using a tool (not shown) such as an impact wrench. As a result, the battery post insertion hole 16 is contracted in the diameter reducing direction, and the battery post insertion hole 16 is in a pressure contact state with the peripheral side surface of the battery post 3. Thus, the connection of the battery terminal 1 with the current sensor is completed. In the battery terminal 1 with the current sensor, the battery post 3 is installed by attaching the first anti-rotation mounting component 63 or the second anti-rotation mounting component 64 to the mounting portion 62 due to the presence of the anti-rotation means 61. It will never rotate around.

  As described above, as described with reference to FIGS. 12 to 18, there is an effect that the battery terminal 1 with a current sensor having a versatile detent can be provided.

  In addition, the present invention can of course be modified in various ways within the scope not changing the gist of the present invention.
