Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connector suitable for supplying large amounts of power, for example, for connecting a power source and equipment.

As a prior example of the subject technology, Japanese Patent Publication No. 59-2704
No. 8 etc. are listed. In this invention, a socket is formed by bundling six conductive strips each having a regular hexagonal cross section to form a hollow body using a spring bundt, and a plug insertion hole defined by each fourth hexagonal conductive strip is inserted into the socket. When the plugs on the power supply side and the equipment side are press-inserted, the diameter expands against the binding force of the conductive strip group or spring hand, allowing the plug to be press-fitted, and the binding force (tightening force) of the band The contact pressure between each conductive strip and the plug is obtained, and when the plug is removed, the diameter of each conductive strip is reduced by the tightening force of the spring band.

The problem to be solved by the invention is that the above-mentioned socket is made up of regular hexagonal conductive strips that are tied together to form a hollow body, and the socket is limited to a six-segmented form, and the number of segments can be increased to create a plug. The structure becomes difficult to increase the number of contacts.

Also, for the same reason, the outer shape of the socket must be shaped like a gear with alternating valleys and peaks; the presence of deep valleys may cause the conductive strips to become deflected, making it difficult to expand and contract properly. In addition, because of the form in which the above-mentioned peaks and peaks are formed alternately, the spring band is able to wrap around the intermittent grooves formed in the peaks, creating an unstable condition that intermittently applies a tightening force to each conductive strip. This provides a solution to the problem that each of the above-mentioned conductive strips becomes an escape mechanism and tends to cause deflection of each of the conductive strips.

Further, the present invention has a structure in which an inner circumferential regulating plate is fitted into an annular groove formed on the inner circumferential surface of the cylindrical socket body, and the inner circumferential surface of the arc-shaped conductive strip group is regulated by the inner circumferential regulating plate. It provides a connector.

Further, the present invention is configured such that an inner circumferential regulating plate is fitted to the inner circumferential surface of the cylindrical socket body to regulate the inner circumferential surface of the arc-shaped conductive strip group, and a plug insertion hole is formed in the inner circumferential regulating plate. The present invention provides a connector configured to screw the end of a fixed plug press-fitted from one end.

According to the present invention, a cylindrical body is divided into an arbitrary number of units to prepare unit arc-shaped conductive strips, and a large number of unit arc-shaped conductive strips A are arranged in a ring to achieve the purpose. A split movable cylindrical socket is obtained.

The number of arc-shaped conductive strips can be increased arbitrarily to form a cylindrical socket corresponding to the amount of power to be supplied.

Furthermore, the above-mentioned conductive strips are formed by cutting hexagonal irregular-shaped bars to a fixed size, but irregular-shaped bars are extremely expensive, and in order to increase the number of divisions of a socket, for example, special processing of hexagonal or larger shapes is required. Since it is necessary to obtain irregularly shaped bars, it is not profitable, and as a result, it is not possible to expect an increase in the number of divisions in the conventional product.

The present invention aims to provide a connector that effectively solves the above problems.

Means for Solving the Problems The present invention, as a distant relative of the above object, divides a regular cylindrical body into multiple parts in the axial direction to form unit arc-shaped conductive strips, and divides an arbitrary number of arc-shaped conductive strips. are arranged in a ring to form a cylindrical socket body, and a spring band is wrapped around a plurality of annular grooves formed along the outer peripheral surface of the cylindrical socket body to expand and contract the conductive strip group of the cylindrical socket body. The present invention provides a connector configured to be easily bundled.

Further, in the present invention, the cylindrical socket main body is made up of a group of unit solid conductive strips, the number of which is greater than the number of divisions, or a group of arcuate conductive strips are arranged in an annular shape, and an annular groove is formed on the circumferential surface of the connection to form a spring. By wrapping the band around the band, it is possible to apply uniform cohesive force to the group of arc-shaped conductive strips, and the arc-shaped conductive strips can be expanded and contracted stably.

Furthermore, since a cylindrical body can be used as a raw material and can be divided into equal parts, a significant cost reduction can be achieved.
