A grommet includes a ring-shaped water stop portion inserted into a through hole formed in an attachment panel and performing water stopping, a closing portion projecting toward radial inside of the water stop portion and closing a ring shape of the water stop portion, a tube portion extending in a direction crossing an axis direction of the water stop portion and provided to penetrate the closing portion and through which a wire material is inserted, and a handle portion provided in an arch shape with respect to the closing portion with a central axis of the water stop portion serving as a center.

An electrical device connector includes: a bus bar which includes a hollow portion extending in an axial direction and through holes extending in an axis-orthogonal direction, and which electrically connects a plurality of switchgears to each other; terminal members including bus bar support portions in which the bus bar is inserted, and including electrical device connection portions in which the insulation plugs are inserted and fixed; and stud bolts each having one end fixed to the corresponding switchgear, each extending in the axis-orthogonal direction through the corresponding through hole, and each fixing the corresponding insulation plug at the other end. Gaps are each formed between the corresponding stud bolt and the bus bar so as to allow communication between the hollow portion and an internal space of the corresponding terminal member.

A bushing comprises an insulating body having a first body end portion, a second body end portion, and a body center portion connecting the first body end portion and the second body end portion, and a bushing conductor coaxially extending within and mechanically coupled to the insulating body. The bushing conductor includes a first connecting portion having a first end face at the first body end portion, a second connecting portion having a second end face at the second body end portion, and a center portion electrically and mechanically connecting the first connecting portion and the second connecting portion. The first connecting portion is elastically deformable with respect to the first body end portion along a radial direction and/or the second connecting portion is elastically deformable with respect to the second body end portion along the radial direction.

The present invention belongs to the technical field of mobile transformer substation, and in particular relates to a vehicle-mounted mobile transformer with a position-adjustable lead-out bushing. In view of the shortage that, when the existing conventional transformer is applied to a vehicle-mounted mobile transformer substation, the transportation dimension exceeds the regulated width, height and limit, the present invention adopts the following technical solution: a vehicle-mounted mobile transformer with a position-adjustable lead-out bushing, comprising: a transformer body; and a high-voltage lead-out bushing, the high-voltage lead-out bushing comprising an oil-SF6 gas bushing, an SF6 gas-air bushing and a connecting device, the oil-SF6 gas bushing being mounted on a high-voltage bushing base, the connecting device being mounted on the oil-SF6 gas bushing, the SF6 gas-air bushing being mounted on the connecting device, and the SF6 gas-air bushing being rotatable relative to the connecting device such that the position of the SF6 gas-air bushing is adjustable. The present invention has the beneficial effects that the SF6 gas-air bushing is rotatable, the position is adjustable and thus the transportation requirement of high-voltage (such as 220 kV) equipment is met.

An anti-kink device for a cable is provided. The anti-kink device for a cable comprises: an anti-kink bush which can be secured on a cable, wherein the anti-kink bush has at least one first snap-in element, a first connecting element which has an opening for the passage of the anti-kink bush, wherein the first connecting element has at least one second snap-in element, a second connecting element which can be connected to the first connecting element, wherein the at least one first snap-in element and the at least one second snap-in element are in such a form that, in a first position of the anti-kink bush relative to the first connecting element, they allow the anti-kink bush to be guided through the opening of the first connecting element and, in a second position of the anti-kink bush relative to the first connecting element, they can be locked together.
