Abstract: A shield wire assembly comprises a shield wire, a conductive ferrule, a wire seal and a stopper. The shield wire includes a central conductor and a braided shielding wire. The ferrule is conductively connected to, and adapted to ground, the braided shielding wire. The stopper is arranged between the ferrule and the wire seal, and includes a first stopper portion suppressing displacement of the ferrule in an inward radial direction and a second stopper portion suppressing displacement of the ferrule in a direction toward the wire seal.

Abstract: A connector configured to be fitted with a mating connector includes a main housing, a sub-housing supported on the main housing to be slidable in a fitting direction with respect to the main housing in which the connector is fitted with the mating connector, and an operating member pivotably and slidably supported on the main housing. The main housing moves closer to the mating connector when the operating member is pivoted from a first posture to a second posture. The sub-housing moves in the fitting direction when the operating member slides from the second posture in a direction different from the fitting direction. The sub-housing has an erroneous fitting prevention part abutting against the mating connector in a state of incomplete fitting of the connector with the mating connector.

Abstract: A VR training system includes: training terminals that generates simulation images for simulation training in common VR space and provides the simulation images to trainees individually associated with the training terminals; and a tracking sensor that detects motion of the trainees in real space. Each of the training terminals calculates a position and a posture of a self avatar in VR space based on a detection result of the tracking sensor, acquires position information on a position and a posture of another avatar in the VR space from another training terminal, and generates the another avatar in the VR space based on the acquired position information.

Abstract: A simulator includes a control stick including a first rotatable control shaft and a second rotatable control shaft; a first reaction force generator including a spring that generates a reaction force to an operation of the first control shaft; a second reaction force generator including a spring that generates a reaction force to an operation of the second control shaft; a motor that displaces the spring to change a neutral position of the first control shaft; and a motor that displaces the spring to change a neutral position of the second control shaft. An output shaft of the motor is located below the first reaction force generator, and an output shaft of the motor is located above the second reaction force generator.

Abstract: A VR training system includes: a training terminal that generates a simulation image for simulation training in VR space and includes an avatar of a trainee linked to action of the trainee in real space and a controller with which the trainee performs an omission action. When an omission action is performed with the controller in a series of actions in the simulation training, the training terminal omits a predetermined action of the avatar and updates the simulation image from a state before the predetermined action to a state after the predetermined action.

Abstract: An aircraft VR training system includes: training terminals that generates simulation images for performing simulation training in common VR space and provides the simulation images to trainees individually associated with the training terminals; and a setting terminal including setting information necessary for generating the simulation images. The setting terminal transmits the setting information to the training terminals. The training terminals set the setting information received from the setting terminal, and transmit setting completion notification of the setting information to the setting terminal. After the setting terminal receives the completion notification from all the training terminals, the setting terminal causes the training terminals to start simulation training.

Abstract: A contact 2 shaped like a plate forming a first socket 201 and a second socket 202 for use in mating includes a first mating portion 21 that constitutes the first socket 201 and that is positioned toward a first side Si with respect to a reference position A, a second mating portion 22 that constitutes the second socket 202 and that is positioned toward a second side S2 with respect to the reference position A, and a connecting portion 23 that is positioned at the reference position A and that connects the first mating portion 21 and the second mating portion 22 to each other. The contact 2 is allowed to be displaced with respect to an engaging pin 111 in both a direction of rotation D1 on a first axis line L1 set along a plate thickness direction (z direction) of the contact 2 at the reference position A and a direction D2 parallel with a second axis line L2 diving the first side Si and the second side S2 from each other at the reference position A.

Abstract: An electrical connector comprises a first housing, a second housing, a lever adapted to couple the first housing and the second housing with each other, a first interlock member, a second interlock member, a first cam mechanism adapted to mate the first housing and the second housing with each other with movement of the lever in a first direction, and a second cam mechanism. The second interlock member is configured to be mated with the first interlock member to energize an electric circuit. The first cam mechanism limits a moving direction of the lever to a second direction after moving in the first direction. The second cam mechanism is adapted to convert the movement of the lever in the second direction into movement in a mating direction of the first housing and the second housing to mate the first interlock member with the second interlock member.

The sub-housing has an erroneous fitting prevention part abutting against the mating connector in a state of incomplete fitting of the connector with the mating connector.

Abstract: A fuse clip comprising a pair of first springs configured to support a fuse having a cylindrical body part from a radially outer side and a pair of second springs disposed side by side with the first springs in an axial direction of the fuse and configured to elastically support the fuse from the radially outer side. The first springs are configured to elastically support the cylindrical body part at a point of intersection between a horizontal line segment passing through a center of the cylindrical body part and an outer circumferential surface of the cylindrical body part or at a position higher than the point of intersection. The second springs are configured to elastically support the cylindrical body part at a higher position with respect to the point of intersection than the first springs elastically support the cylindrical body part.

Abstract: An electrical connector comprises a first housing, a mating terminal retained in the first housing, a second housing mated with the first housing, a contact member disposed in the second housing, and an insertion/extraction assist protrusion. The contact member is electrically connected with the mating terminal by pinching the mating terminal with a plurality of spring pieces facing each other. The spring pieces each have a contact portion protruding inward. The insertion/extraction assist protrusion is adapted to expand a gap between the spring pieces when the first housing and the second housing move relative to one another in a mating direction. The insertion/extraction assist protrusion is arranged offset from the contact portions in a plane crossing the mating direction and is arranged nearer to a start point of the mating than the contact portions during the mating in the mating direction.

Abstract: A plug connector is detachably matable with a cap connector. The plug connector includes a lever performing mating with and unmating from the cap connector. The lever includes a cam groove for receiving a first boss of the cap connector, a boss rotation hole for receiving a second boss of an outer housing of the plug connector, and a catching protrusion sliding hole for receiving a catching protrusion of an inner housing of the plug connector. A first turning operation of the lever during unmating from a fully mated state extracts an interlock busbar of the plug connector from the cap connector to remove a short circuit of first conducting wires of the cap connector. A second turning operation of the lever during unmating moves a releasing protrusion into a clip spring of the plug connector to open the clip spring.
