Embodiment Construction

[0046] In the figure, symbol 10 represents clip, such as figure 1 and Figure 8 As shown, the clip 10 holds the temperature sensor 20 and is attached to an attachment hole 31 penetrating inside and outside a case 30 housing a storage battery (not shown).

[0047] Although not shown, the storage battery is used in an electric vehicle or a hybrid vehicle, and is configured as a module in which single cells are stacked. Although not shown, the battery is mounted on the vehicle in a state of being accommodated in the case 30 . The storage battery generates heat through the electrochemical reaction inside, and its temperature rises. If the temperature reaches a high temperature, the power generation efficiency of the battery decreases, so the battery is accommodated in the case 30 with high thermal conductivity, and cooling air is sent from the outside for cooling. In order to control the supply of cooling air, the temperature inside the casing 30 is measured by the temperature ...

Abstract

Provided is a clip which comprises: a contact part for making contact with the outer surface of a case; an insertion hole which can have a sensor main body inserted therein; a holding tube which can have the sensor main body pass therethrough, and can hold a protruding part therein; a leg tube which can be inserted in an attachment hole; and an elastic hook for holding the case between the contact part and the elastic hook. At least a pair of ribs is provided positioned at both ends of the contact part in a radial direction thereof and protruding toward the outer surface of the case. When the case is held between a pair of the elastic hooks and the ribs, a force is applied to the holding tube in a direction in which the contact part is bent and an open end surface is contracted.

Description

technical field [0001] The present invention relates to a clip for mounting a temperature sensor for a storage battery, which can improve and maintain mounting accuracy by preventing the temperature sensor from falling off, moving, or shaking. Background technique [0002] Conventionally, the battery structure of an electric vehicle equipped with a temperature sensor unit is well known (for example, refer to paragraph number 0034 of Patent Document 1, figure 1 , Figure 6 ~ Figure 8 ). [0003] The temperature sensor unit includes: a cylindrical unit main body having a threaded portion screwed into a sensor mounting hole on the upper wall of the battery case; a synthetic resin temperature detection portion slidably disposed inside; A temperature sensor at the front end of the temperature detection unit; and a spring elastically installed in the unit body and biasing the temperature detection unit in a direction in which the temperature detection unit protrudes from the uni...
