CROSS REFERENCE TO RELATED APPLICATIONS

This application is a national phase of PCT application No. PCT/JP2019/009868, filed on 12 Mar. 2019, which claims priority from Japanese patent application No. 2018-066980, filed on 30 Mar. 2018, all of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a connector to be mounted on a device having a cylindrical shape and a device with connector including this connector.

BACKGROUND

Conventionally, a device connector used by being mounted on a device disposed in an automatic transmission of a vehicle is described, for example, in patent literature 1.

In this technique, a connector housing projects on the outer peripheral surface of a tubular device. The connector housing includes a receptacle, and a terminal electrically connected to the device is disposed to project into the receptacle. The above device is, for example, a solenoid having a coil disposed inside.

The device connector is provided with a lock hole penetrating through an upper wall of the device connector at a position above the terminal and configured to lock a mating connector. A locking portion of the mating connector is resiliently fit into this lock hole, whereby the mating connector and the device connector are held in a connected state.

SUMMARY OF THE INVENTION

Problems to be Solved

However, since the lock hole is disposed above the terminal in this technique, there has been a problem that the device connector is enlarged upward.

The technique disclosed in this specification was completed on the basis of the above situation and aims to provide a technique related to height reduction of a connector.

Means to Solve the Problem

The technique disclosed in this specification is directed to a connector to be disposed on an outer peripheral surface of a device having a cylindrical shape, the connector including a leg portion projecting radially outward of the device, a receptacle formed along the outer peripheral surface of the device from a tip part of the leg portion and fittable to a mating connector, a plurality of terminals embedded in the leg portion and disposed along the outer peripheral surface of the device in the receptacle, and a locking portion disposed between the plurality of terminals and configured to lock the mating connector.

According to the above configuration, since the locking portion is disposed between the plurality of terminals, a height of the connector can be reduced as compared to the case where the locking portion is disposed above the plurality of terminals.

The following modes are preferable as embodiments of the technique disclosed in this specification.

The leg portion is provided at a center position of the receptacle in a direction along the outer peripheral surface of the device.

According to the above configuration, a force received from the mating connector by the receptacle can be received equally in the direction along the outer peripheral surface of the device by the leg portion when the mating connector is fit into the receptacle. In this way, the application of a force in a direction to twist the receptacle about the leg portion can be suppressed when the mating connector is fit.

The locking portion is provided at a center position of the receptacle in the direction along the outer peripheral surface of the device.

According to the above configuration, the height of the connector can be further reduced since a space between the plurality of terminals can be effectively utilized.

Further, the technique disclosed in this specification is directed to a device with connector including a device having a cylindrical shape extending along an axial direction, a connector to be disposed on an outer peripheral surface of the device, and a magnetic shield member made of metal, to be mounted outside the device and having a tubular shape open on one end part, the magnetic shield member including an avoidance recess formed into a concave shape from an opening end of the one end part to avoid interference with the leg portion.

According to the above configuration, a clearance is provided between the device and the receptacle by the leg portion projecting from the side wall of the device, and the magnetic shield member is inserted into this clearance. A part of the device not covered by the magnetic shield member is a region where the magnetic shield member is provided with the avoidance recess. In this way, the part of the device not covered by the magnetic shield member can be made smaller, wherefore the magnetic field efficiency of the device can be improved.

The device includes a front wall located on a front side and a rear wall located on a rear side with respect to the axial direction, the magnetic shield member includes a front shield portion extending along the front wall of the device and a side shield portion extending along a side wall of the device, and an end part of the side shield portion is formed into a bent portion bent along the rear wall and connected to the side shield portion.

According to the above configuration, the rear wall of the device is at least partially covered by the bent portion. In this way, the front shield portion, the side shield portion and the bent portion of the magnetic shield member are magnetically connected, wherefore the magnetic field efficiency of the device can be further improved.

Effect of the Invention

According to the technique disclosed in this specification, it is possible to reduce a height of a connector.
