Description

Technology Field

[0001] The present invention relates to a rotational torque measuring device for a relay terminal, and more specifically, to a rotational torque measuring device for a relay terminal capable of measuring rotational torque by fixing a relay to a main body and connecting the other end to a rotational torque measuring device for stable and accurate measurement. Background Technology

[0003] Generally, electric vehicles (EVs) are equipped with various relays. Relays are important electrical components used to control electrical circuits.

[0004] There are various types of relays for electric vehicles, and the main relay can connect or disconnect the high-voltage battery pack from the vehicle's electrical system (motor, inverter, etc.). The main relay must be capable of controlling high voltage and high current; it ensures safety by disconnecting the circuit when the EV is turned off, and operates to supply power to the system when the vehicle is started.

[0005] A pre-charge relay can prevent sparks or voltage surges by pre-charging the circuit's capacitor before the main relay operates. In high-voltage systems, it can mitigate current surges (inrush current) and extend the lifespan of the main relay. Generally, small relays capable of handling low currents are used.

[0006] The charge relay controls the current flow between the battery management system (BMS) and the charger during the charging process. It is characterized by preventing overcharging by operating the relay according to the charge state. It detects and activates the charger when it is connected from outside the vehicle.

[0007] In addition, there are auxiliary relays that control auxiliary systems such as air conditioning, heating, and lighting, and safety relays that quickly cut off the circuit in the event of an accident to prevent fire or electrical hazards.

[0008] In this context, considerations for relay design include safety, miniaturization, and efficiency, as well as durability requirements that enable long-term operation in the high-voltage, high-current environment of an EV.

[0009] EV relays are manufactured using advanced materials and technology to ensure electrical safety and efficiency. In particular, high-voltage relays are characterized by the need to meet higher requirements compared to relays in standard vehicles.

[0010] According to the prior art, with reference to FIG. 1, this is a configuration diagram of a rotational torque measuring jig for a conventional automotive relay HV (high voltage) terminal. Reference numeral 1 is a jig for fixing a relay, and a large number of taps are applied to prevent the relay from rotating together during rotational torque measurement, so as to measure the torque of multiple relays or to be compatible with various models of relays. After fixing the relay (2) to the jig (1) with an M5 bolt and temporarily tightening the bolt to the HV terminal, a rotational torque measuring device (3) combined with a socket is placed on the bolt to perform the measurement.

[0011] The method according to the prior art had a problem due to the following reasons, which made it difficult to measure rotational torque.

[0012] First, when measuring by placing the rotational torque measuring device (3) combined with the socket on the relay (2), there is no problem at low torque, but at high torque, the main body of the rotational torque measuring device (3) rotates or shakes together, making it difficult to obtain an accurate torque graph result.

[0013] Second, in the case of a horizontal type (side mounting) relay, since the relay fixing part is located on the side, the relay (2) cannot be fixed to the existing jig (1), making measurement impossible.

[0014] Third, accurate measurement is possible only if the horizontal alignment of the bolt temporarily fastened to the HV terminal of the relay (2) and the socket of the rotational torque measuring device (3) is aligned, but it is difficult to achieve this with the conventional method. In other words, accurate measurement is difficult when measuring rotational torque because it is affected by the fastening angle.

[0015] Fourth, the thickness of the busbar used for automotive relays varies depending on the vehicle model. That is, although the height of the relay HV terminal is the same, the position of the bolt to which it is fastened changes. Accordingly, the position of the rotational torque measuring device (3) must also change, but there is an inconvenience in the existing measurement method. The problem to be solved

[0017] The present invention aims to solve the aforementioned problems. The objective of the present invention is to provide a rotational torque measuring device for relay terminals capable of measuring rotational torque by stably fixing the relay and the rotational torque measuring device to obtain more accurate torque graph results, and by designing it to be compatible with side-mounting type relays.

[0026] At this time, the torque measuring device fixing part may include a support block on which the torque measuring device is fixed, with its lower surface in close contact with the lifting block and its upper surface.

[0027] At this time, the support block has a rotation axis formed on both sides so that its height and angle can be adjusted, and the rotation axis can be assembled by being inserted into a second slot formed in the side panels on both sides.

[0028] At this time, it may include a second adjustment screw that is screw-coupled by vertically penetrating the side panel and fixes the support block by pressing the rotation axis of the support block at its end.

[0029] At this time, the support block is provided with an extension panel extended in one direction, and a first level may be installed on the extension panel.

[0030] At this time, the support block may be formed with one end rounded around the rotation axis.

[0031] At this time, a plurality of spacers having different thicknesses may be included to adjust the height of the lifting block.

[0032] At this time, a second level installed on the upper surface of the base panel to adjust the overall level may be included. Effects of the invention

[0034] According to the above configuration, the rotational torque measuring device of a relay terminal according to one aspect of the present invention can derive accurate torque graph results because, when measuring by placing a rotational torque measuring device on the relay, there is no phenomenon where the measuring device body rotates or shakes together even at high torque.

[0035] According to another aspect of the present invention, the rotational torque measuring device of a relay terminal is designed to be compatible with a horizontal type (side-mounting) relay, thereby increasing the utility of the torque tester.
