As described above, the high voltage connector 1 according to the embodiment includes a connector terminal 20, a housing 10, a bus bar 30, a sensor 70, and a control board 40. The connector terminal 20 is a terminal that can be connected to the mating terminal accommodated in the mating portion of the mating connector. The housing 10 accommodates the connector terminal 20 and has a fitting portion 12 that is fitted to the mating portion. The bus bar 30 has a conductive, plate-like shape, includes a main surface 32 having a relatively large area, and is connected to the side opposite to the mating connector terminal side of the connector terminal 20. The sensor 70 detects a physical quantity related to the bus bar 30. The control board 40 has a plate-like shape, includes a main surface 41 having a relatively large area, and mounts a sensor 70. The bus bar 30 and the control board 40 are assembled to each other with the main surface 32 of the bus bar 30 and the main surface 41 of the control board 40 facing each other.

With this configuration, when the high voltage connector 1 includes a voltage sensor 71, a current sensor 72, and a temperature sensor 73 as a plurality of sensors 70, the housing 10 has these sensors 71 to 73 integrated on the control board 40. It can be assembled to, and the assembling property of each sensor 71 to 73 can be improved. Further, since the high voltage connector 1 is assembled with the main surfaces of the bus bar 30 and the control board 40 facing each other, it is compared with the case where the main surfaces of the bus bar 30 and the control board 40 cannot be assembled with each other facing each other. Then, when making an electrical connection, the bus bar 30 and the control board 40 can secure a relatively wide area for each electrical connection, whereby the electrical connection can be properly performed. be able to. Further, when the high voltage connector 1 detects the temperature of the bus bar 30, the bus bar 30 and the control board 40 can secure a relatively wide area for heat conduction, so that the high voltage connector 1 can be controlled with the bus bar 30. It is possible to suppress a decrease in thermal conductivity between the substrate 40 and the substrate 40.

Further, in the high voltage connector 1, the temperature sensor 73 can be arranged in the vicinity of the connector terminal 20, and the temperature can be detected in the vicinity of the connector terminal 20, so that deterioration of the temperature detection accuracy can be suppressed. As a result, the high voltage connector 1 can properly assemble a plurality of sensors 70. By mounting a plurality of sensors 70, the high voltage connector 1 can detect a plurality of physical quantities (for example, voltage, current, temperature, etc.) related to the bus bar 30, and thus can be enhanced in functionality. Since the high-voltage connector 1 integrates a plurality of sensors 70 on the control board 40, the high-voltage connector 1 can be miniaturized.

The voltage sensor 71 detects the voltage applied to the connector terminal 20 via the bus bar 30 and the conductive member 50. With this configuration, the high voltage connector 1 can omit connecting the bus bar 30 and the voltage sensor 71 with an electric wire as in the conventional case. As a result, the high voltage connector 1 can suppress an increase in the number of parts and can simplify the configuration. Further, the high voltage connector 1 can facilitate the assembling work of the voltage sensor 71.

In the high voltage connector 1, the main surface 32 of the bus bar 30 includes a connection main surface 32a facing the side opposite to the fitting portion 12 of the housing 10.

In some cases, the conductive member 50 may not be provided.

Further, when the high voltage connector 1 is provided with only the temperature sensor 73 without the voltage sensor 71 and the current sensor 72, it is not necessary to electrically connect the bus bar 30 and the control board 40, but in this case, it is relative. It is preferable to physically connect the bus bar 30 and the control substrate 40 by a heat conductive member having a high heat conductivity.

The example in which the control board 40 and the bus bar 30 are electrically connected to the high voltage connector 1 via the conductive member 50 has been described, but the present invention is not limited thereto. The high-voltage connector 1 may electrically connect the control board 40 and the bus bar 30 without using the conductive member 50 by, for example, co-fastening the control board 40 and the bus bar 30 with bolts for co-tightening. Further, the high voltage connector 1 is configured to provide a protrusion (terminal or the like) for taking in voltage and temperature on the bus bar 30 so that the protrusion (terminal or the like) is connected to the wiring pattern on the control board 40 by solder or the like. You may.

Although the example in which the conductive member 50 is solder has been described, the conductive member 50 is not limited to this, and may be, for example, a member such as a heat conductive sheet having conductivity.

An example has been described in which the bus bar 30 and the control board 40 are assembled to each other with the connection main surface 32a of the bus bar 30 and the main surface 41 of the control board 40 facing each other, but the present invention is not limited thereto. For example, the bus bar 30 and the control board 40 may be assembled to each other with the main surface 32 at a position different from the connection main surface 32a of the bus bar 30 and the main surface 41 of the control board 40 facing each other.

The present invention has described an example of applying to a high voltage connector 1 constituting a power supply circuit when supplying electric power supplied from a high voltage battery to a load unit, but the present invention is not limited to this, and is applied to a low voltage connector. May be good.

Although the example in which the connector terminal 20 is a male terminal has been described, the connector terminal 20 is not limited to this and may be a female terminal.

Although the example of detecting the current by the Hall IC 72b has been described, the current sensor 72 is not limited to this, and may be, for example, a current sensor using a shunt resistor or the like.

The temperature sensor 73 has described an example of detecting the temperature by a PTC thermistor, but the temperature sensor 73 is not limited to this, and may be, for example, a semiconductor temperature sensor using a Si diode or the like.
