Abstract

PURPOSE:To make it possible to increase the number of conductive strips according to the selection of dividing angle so as to divide a cylinder into parts with a proper number corresponding to the use conditions and make proper contact by forming a cylindrical socket which is a divided and movable one prepared by dividing a cylindrical body into an optional number by conductive strips. CONSTITUTION:A cylindrical material which is prepared by cutting a long pipe into a constant length is divided equally in the axial line direction in its diameter line and a plurality of arc-shape conductive strips 1 are obtained. Each arc-shape conductive strip 1 is cut in the periphery part 4 along with a dotted line 3, finishing-processed to form a plane surface 2, and after predetermined angle treatment and end plane treatment, each of the resultant arc-shape conductive strip 1 are closely arranged to recompose a completely cylindrical body and a socket body 5 having a plug insertion hole 6 opened in both ends composed with the conductive strips 1 is formed. As a result, the outer circumference of the completely cylindrical socket body 5 becomes completely circular and the inner circumference for plug insertion hole 6 becomes surface treated polyhedron shape. The number of the conductive strips can be increased freely according to the dividing angle and proper contact can be retained by dividing into proper numbers based on supplied electric power.

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. 5927048
The number, etc. will be listed. In this invention, six conductive strips having a regular hexagonal cross section are tied together with a spring band to form a hollow body to form a socket, and a plug insertion hole defined by each hexagonal conductive strip is provided with a power source. When the plugs on the side and equipment side are press-inserted, the conductive strip group resists the binding force of the spring hunt and expands in diameter to allow the plug to be press-fitted, while the band's binding force (tension force) The structure is such that contact pressure between the conductive strip and the plug is obtained, and when the plug is removed, the diameter of each of the 48 strips is reduced by the tightening force of the spring band.

The problem to be solved by the invention is that since the above-mentioned socket is made of regular hexagonal conductive strips that are tied together to form a hollow body, the socket is necessarily limited to a six-part shape, and the number of parts is increased. The structure becomes difficult to increase the number of contact lines with the plug.

Also, for the same reason, the outer shape of the socket has to be shaped like a gear, with valleys and peaks formed alternately.The existence of valleys causes deviations in the conductive strips, making it difficult to expand and contract appropriately. In addition, since the above-mentioned shapes and ridges are formed alternately, Spring Hunt is unstable in that it wraps around the intermittent grooves formed in the ridges and supports the conductive strips in the centripetal direction. Not only is it impossible to tightly wrap the spring hands around the entire circumference of the socket to provide a uniform binding force, but also each of the above serves as an escape groove for the conductive strips to prevent deflection of the conductive strips. Identifies problems that are likely to occur.

Furthermore, in the above-mentioned connector, the conductive strips are formed by cutting a hexagonal irregular-shaped bar into a fixed size, but irregular-shaped bars are expensive and, for example, in order to increase the number of socket divisions, it is necessary to Since it is necessary to obtain specially processed irregular-shaped bars that are square or larger,
This is difficult to implement economically, and as a result, it is difficult 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 means to achieve the above object, forms a socket body by reorganizing arc-shaped conductive strips formed by equally dividing a regular cylindrical body in the axial direction into a regular cylindrical shape. A spring band is wound around a plurality of annular grooves formed along the circumferential surface of the cylindrical socket body to expand and contract the conductive strips of the cylindrical socket body. be.

Furthermore, depending on the implementation, an annular engagement groove is formed on the inner circumferential surface of the cylindrical socket body, a mounting bracket is fitted into this, and the end of the fixed plug is press-fitted into the mounting bracket from one end of the plug insertion hole. The socket is fixed with screws, and the fixing plug is removably fixed to the socket body.

According to the present invention, the desired split movable cylindrical socket can be obtained by reorganizing the conductive strips obtained by dividing the cylindrical body into an arbitrary number of pieces and performing appropriate processing. The number of conductive strips can be freely increased by selecting . Therefore, proper contact can be ensured by dividing the power into a number corresponding to the amount of power to be supplied.

In addition, since each conductive strip is closely attached to each other and reproduced as a regular cylindrical body, it is possible to form an uninterrupted groove on the circumferential surface and wrap the band around it, giving equal cohesive force to each conductive strip.
Each conductive strip can be expanded and contracted stably. In addition, since the cylindrical body can be divided and formed as a material, cost reduction can be achieved.
