Abstract

Provided is a connector capable of simplifying the operation of assembling a rear holder to a housing. The connector (1) is provided with a rod-shaped terminal (10A), a terminal holder (20) for holding the terminal (10A), and a housing (30) to which the terminal holder (20) is attached. The terminal holder (20) has a plurality of locking parts (241, 242, 243) arranged in the circumferential direction of the terminal (10A), and the plurality of locking parts can elastically displace in the radial direction of the terminal (10A) and engage with the terminal (10A) to limit the movement of the terminal (10A) in the radial and axial directions. The locking portion (241) has a through hole (28) and support walls (29, 29) protruding radially outward from the peripheral edge of the through hole (28). The temperature sensor (50) is disposed adjacent to the terminal (10A) and passes through the through hole (28) and along the support walls (29, 29).

Description

Connector with a plurality of connectors Technical Field The present invention relates to a connector. Background Conventionally, a connector for supplying power (charging) from the outside of a vehicle to a battery mounted in a vehicle such as an electric vehicle or a plug-in hybrid vehicle has been proposed. The power supply connector is connected to a power source or the like outside the vehicle, and is connected to be inserted into a charging socket provided in the vehicle (for example, refer to patent document 1). Further, such a connector is also referred to as a charging connector. Prior art literature Patent literature Patent document 1 Japanese patent application No. 6475669 Disclosure of Invention Technical problem to be solved by the invention In the conventional charging connector described above, after a plurality of rod-shaped terminals are sequentially inserted into the terminal accommodating chambers of the housing and temporarily fixed (so-called temporary locking), the rear holder is assembled to the housing, so that the plurality of terminals are finally fixed (so-called main locking) to the housing. In addition, in a conventional charging connector, a temperature sensor is often provided via a metal sheet in contact with the peripheral surface of a terminal in order to measure the temperature of the terminal. In this case, at the time of the temporary fixation, a metal piece is assembled to the peripheral surface of the terminal, and then the temperature sensor is assembled to the metal piece. Thereby, the temperature sensor is arranged between the housing and the rear holder. However, in the conventional charging connector, when the rear holder is assembled to the housing, it is necessary to assemble the metal sheet and the temperature sensor in a temporarily fixed state, leaving room for improvement. The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector capable of simplifying the operation of assembling a rear holder to a housing. Technical means for solving the technical problems In order to achieve the above object, the connector of the present invention is characterized as follows. A connector comprising a rod-shaped terminal, a terminal holder for holding the terminal, and a temperature sensor capable of measuring the temperature of the terminal, The terminal holder has a plurality of locking parts arranged in the circumferential direction of the terminal, the plurality of locking parts can elastically displace in the radial direction of the terminal and engage with the terminal to limit the movement of the terminal in the radial direction and the axial direction, One of the plurality of locking parts is provided with a through hole penetrating the locking part and a supporting wall protruding radially outwards from the periphery of the through hole, The temperature sensor is disposed adjacent to the terminal and along the support wall through the through hole. Effects of the invention According to the connector of the present embodiment, the operation of assembling the rear holder to the housing can be simplified. The present invention is briefly described above. Further, the details of the present invention will be further clarified by reading a mode for carrying out the invention described below (hereinafter, referred to as "embodiment") with reference to the drawings.

Detailed Description < Embodiment > Hereinafter, a connector 1 according to an embodiment of the present invention will be described with reference to the drawings. The connector 1 is provided in a vehicle such as an electric vehicle or a plug-in hybrid vehicle, and is a connector connected to an electric wire 2 extending from a battery, a device, or the like mounted in the vehicle. The connector 1 is also referred to as a charging jack. When the mating connector (so-called charging gun) is fitted into the fitting opening 37 (see fig. 1) of the connector 1, electric power is supplied from a power source or the like outside the vehicle to the battery, and the battery is charged.
