Abstract

PURPOSE: To provide a split-clamp joint terminal which can connect even a thin electric wire therewith firmly, without cutting off an end portion of the electric wire by forming two split-clamp connecting pieces thereon by means of providing a split-clamp connecting slit that extends from a center of a lateral fringe to a hole parallel to a vertical fringe. CONSTITUTION: A cut 15, which extends from a split-clamp connecting slit 19 in parallel to a lateral fringe 8, keeping a distance from the lateral fringe 8, is formed in split-clamp connecting pieces 11 and 12, and a split-clamp knife- shaped part 14 which extends form a cut 15 to a hole 10 is formed. Further, the split clamp connecting slit 19 having predetermined dimensions is formed between knife edge parts 18 of the split-clamp knife shaped part 14, by bending uniformly the split-clamp knife-shaped part 14 from a plate surface. therefore, the split-clamp joint terminal can connect an electric wire therewith by utilizing soft elasticity thereof. Thus even with a thin electric wire, it can be surely connected to the split-clamp joint terminal without cutting off an end portion thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is intended for use with thin electrical wires, such as enamelled wires, made from a flat plate material and provided with at least one wide contact portion for making an electrical connection. Split clamp connection terminal for split clamp connection, having two vertical edges and one horizontal edge that is the insertion side or free end, from the center of the horizontal edge to the hole parallel to the vertical edge. The invention relates to an elongated split-clamp connection slit, by means of which two split-clamp connection pieces are created.

[Prior Art] This type of split clamp connection terminal is disclosed in German Patent Publication No. 35.
It is known since 26707. In this split clamp connecting terminal, the split clamp connecting piece is too hard, and in the case of a very thin electric wire such as an enameled wire, for example 0.08 mm, this electric wire is inserted into the connecting slit between the connecting pieces of this known split clamp connecting terminal. It has the disadvantage that it cannot be used because it is cut off by a knife-like part inside. Moreover, it is also very difficult to produce very narrow slits with a certain spacing between the knives for such thin wires.

[Problems to be Solved by the Invention] An object of the present invention is to create a split clamp connection terminal having a predetermined slit width in a simple manner, thereby making it possible to connect a very thin electric wire without cutting it. be.

[Means for Solving the Problems] According to the present invention, the above problem is achieved by forming a notch in the split clamp connecting piece that extends parallel to the horizontal edge from the split clamp connecting slit at a distance from the horizontal edge. , thereby forming a split clamp knife-shaped part extending from this cut to the hole, and the split clamp knife-shaped part is uniformly bent from the plate surface, thereby forming the split clamp connecting slit with predetermined dimensions. This problem is solved by forming the split clamp knife-like part between the knife parts.

[Operation and Effects of the Invention] In other words, since the clamp knife-shaped portion is formed in a bent manner, electric wires can be connected with soft elasticity, thereby making it possible to cut off even thin electric wires. This allows you to connect reliably without any problems.

Other preferred embodiments of the invention are described in the dependent claims.

[Example] Next, the present invention will be explained in detail using the drawings.

The split clamp connection terminal l is produced by die-cutting from a plate material and is a component of an electrical connection means, which is provided with at least one contact part 4 for electrical connection in the vicinity of the split clamp connection terminal l. The connecting means 5 shown in FIGS. 1 to 6 comprises two similarly designed split clamp connections 2, 3 arranged at a distance from each other. Since the contact part 4 has no significant bearing on the function of the split clamp connection part 2, 3 according to the invention, its shape will not be described in detail in this specification.

The split clamp connection terminal l is made from a flat, substantially rectangular plate and has longitudinal edges 6, 7 and a transverse edge 8 on the insertion side. A contact portion 4 is integrally connected to a side of the plate material opposite to this side edge 8.

A cutting line extending parallel to the vertical edges 6 and 7 from the center 9 of the horizontal edge 8 is processed into the plate material, and this cutting line
The circular hole 10 is reached in the region . This cutting line allows two adjacent split clamp connection pieces 11.1
2 is formed.

In the present invention, the plate material is provided with a notch 13 extending parallel to the lateral edge 8 from the cutting line at a distance from the lateral edge 8 in the direction of the hole IO in the split clamp connection pieces 11 and 12. A split clamp knife-shaped portion 14 extending from 13 to hole IO is formed. This notch 1
3, that is, the width of the knife-shaped portion 14 is at least the length of the hole l.
4 of the width of O, where equal to the radius of the hole 10,
Preferably, the length is longer than this, for example equal to the total width of the hole 10, that is, the diameter of the hole IO.

The split clamp knife-shaped part 14 created by the cut 13 and the hole 10 is bent uniformly from the plate surface, preferably with two bending edges 15, 16, so that the knife part 18 of the split clamp knife-shaped part 14 A connecting slit 19 having a predetermined length is formed between them.

By cutting diagonally from the lateral edge 8, preferably to the notch 13, a diagonal edge 17 and, consequently, a tapered inlet 20 can be created by this diagonal edge 17.

The cut 13 makes it easy to bend the split clamp knife-shaped portion 14 from the plate surface, and it is possible to reliably give the split clamp connection slit 19 a predetermined dimension. Furthermore, the plurality of bending edges 15 and 16 soften the elasticity of the split clamp knife-like part 14 in accordance with the number of bending edges, so that the knife 18 of the knife-like part 14 does not cut the electric wire. In this way, split clamp connection terminals for thin electrical wires, in particular enamelled wires, can be produced in a simple manner.

In the present invention, it is also possible to provide the connecting means 5 with two split clamp terminals 2 and 3 extending in parallel (FIGS. 1 to 3). Furthermore, according to the invention, it is also possible to provide a wall member 21 between two opposing split clamp connection pieces 2.3, so that the split clamp part with a U-shaped cross section has high stability and its Even in this case, the elastic force of the split clamp knife-like portion 14 is not adversely affected.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
