Next, as shown in FIG. 2, the sensor unit 5 is integrally formed and the clip holder 24 is provided on the upper surface of the sensor unit 5.
The operation will be described based on an example (second example of a device for mounting a current sensor).

First, the penetrating portion 4 of the sensor portion 5 (magnetic core)
The current wire 2 to be measured such as a wire harness (battery cable) is inserted into and the sensor part 5 is moved to a desired mounting position of the current wire 2 to be measured. After the movement, the engagement frame portion 26 of the clip holder 24 and the protrusion 23 of the sensor portion 5 are engaged with each other,

Band portion 14 is inserted, and the tip of the band portion 14 that penetrates the clip insertion hole 30 is folded back in the direction opposite to the insertion direction above the sensor portion 5 and inserted into the band insertion hole 12 to form the band stop portion 16. Lock it. Then, the band engaging portion 17 of the band clip 11 is press-fitted into the mounting hole 13 of the band clip holding portion 12 of the battery 10, for example. As a result, the band clip 11 is held by the band clip holding portion 12.

In the case shown in FIG. 4, after the sensor body 3 is moved to the desired mounting position of the current line 2 to be measured, the mounting portion 42 is mounted.
The engaging member 41 is attached to. Then, the engaging portion 40 of the engaging member 41 is press-fitted into the engaging portion 44 of the battery tray 43, for example. As a result, the engaging member 41 is moved to the battery tray

According to the third aspect of the present invention, the sensor main body can be attached by binding and holding an arbitrary portion of the current line to be measured with a band clip, so that the vehicle and the components mounted on the vehicle are not affected. The current sensor can be easily attached.

According to the fourth aspect of the invention, the current sensor is held by the vehicle and the vehicle-mounted object fixed to the vehicle via the band clip, so that the current sensor can be stably attached without swinging. be able to.

According to the fifth aspect of the present invention, the current sensor is held by the band clips provided at the upper ends of both wall surfaces forming the penetrating portion of the sensor body.
The current sensor can be mounted stably and reliably.

According to the sixth aspect of the present invention, since the current wires to be measured coming out from both sides of the penetrating portion are bound by the two band clips of the clip holder, the current sensor can be attached stably and securely. You can do it.

According to the invention described in claim 7, the current sensor is held by the vehicle and the vehicle-mounted object fixed to the vehicle via the band clip, so that the current sensor is stably attached without swinging. be able to.

According to the invention described in claim 8, since the mounting member comprises the clip insertion hole of the sensor body and the band clip having the band engaging portion, the current sensor can be stably mounted with a simple structure. You can

According to the invention described in claim 9, since the mounting member is provided on the sensor body and includes the band engaging member having the band engaging portion, the current sensor can be stably mounted with a simple structure. You can
