Clip for attaching battery temperature sensor
A clip includes an abutting portion abutting against an outer surface of a case; an insertion hole to which a sensor main body can be inserted; a holding tube through which the sensor main body can pass, and can internally hold an overhanging portion; a leg tube which can be inserted into an attachment hole; and elastic claws sandwiching the case between the abutting portion and the elastic claws. In the abutting portion, at least a pair of ribs is provided, which is positioned respectively in both end portions in a diametrical direction of the abutting portion; protrudes toward the outer surface of the case; and applies a force to the holding tube in a direction bending the abutting portion and narrowing an open end surface when the case is sandwiched between the pair of elastic claws and the ribs.
1. A clip for attaching a battery temperature sensor, which holds a temperature sensor including a sensor main body and an overhanging portion overhanging from a circumference of a base end portion of the sensor main body; is attached to an attachment hole penetrating in and out through a case housing a battery; and allows an end portion of the sensor main body to protrude into the case, comprising:
an abutting portion having a diameter larger than that of the attachment hole, and abutting against an outer surface of the case;
an insertion hole passing through the abutting portion, and having a diameter smaller than that of the overhanging portion so as to insert the sensor main body;
a holding tube communicated with the insertion hole, extending in a tube shape toward an outside of the case from the abutting portion, and opening at an end surface so as to insert the sensor main body to pass through the insertion hole from an open end surface, and to internally hold the overhanging portion;
a leg tube communicating with the insertion hole, extending in a tube shape toward an inside of the case from the abutting portion, and opening at an end so as to insert the sensor main body to pass through an end opening from the insertion hole, and to be able to insert into the attachment hole; and
at least a pair of elastic claws elastically protruding from an outside surface of the leg tube, bending toward a tube inner portion of the leg tube when the elastic claws pass through the attachment hole, and restoring to its original state after passing through the attachment hole so as to sandwich the case between the abutting portion and the elastic claws,
wherein the abutting portion includes at least a pair of ribs respectively positioned in two end portions in a diametrical direction of the abutting portion, protruding toward an outer surface of the case, and applying a force to the holding tube in a direction bending the abutting portion and narrowing the open end surface when the case is sandwiched between the pair of elastic claws and the ribs.
2. A clip for attaching a battery temperature sensor according to claim 1 , wherein the holding tube includes at least a pair of slits opening in a direction orthogonal to an opposed direction of the pair of ribs, and extending up to a middle toward the holding tube from the open end surface.
3. A clip for attaching a battery temperature sensor according to claim 1 , wherein an inner circumferential surface of the holding tube includes internal projections protruding toward a tube inner portion of the holding tube, and extending along an insertion direction of the temperature sensor.
4. A clip for attaching a battery temperature sensor according to claim 1 , wherein an inner circumferential surface of the holding tube includes locking portions positioned in a middle in the insertion direction of the temperature sensor, protruding toward the tube inner portion of the holding tube, abutting against an outside surface of the overhanging portion, elastically bending in a direction expanding a diameter of the holding tube upon pressing by the outside surface, and restoring to its original state after the outside surface has passed through so as to sandwich the overhanging portion between the abutting portion positioned at a bottom of the holding tube and the locking portions.
