Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a flat couple connector.

[Background technology]

Traditionally, flat cables have been used as part of office automation to allow electricity to be brought in from anywhere on the carpet. The following requirements are required for a connector that connects these flat cables together under a car vent: ■The overall thickness after joining must be thin. ■Good workability. In other words, the merging should not take too long. ■The connection must be mechanically stable. Examples include.

As a conventional flat cable connector,
Publication No. 5-161382 and Japanese Unexamined Patent Publication No. 55-22514 have been published. All of these are formed by providing electrical connection protrusions and mechanical connection protrusions on the inner surface of a metal plate piece folded in two. However, there was a problem in that the prevention of opening of the metal plate piece due to the bending of the tip of the mechanical connection protrusion was insufficient. Additionally, there was a problem in that the metal plate pieces opened and the electrical connection became unstable.

In the former case, the electrical connection protrusion is annular, and the annular protrusion must break through the insulation of the flat cable and bite into the flat conductor.
Pushing the button down required a considerable amount of force, and the workability was poor. The latter is easier to connect than the former because the electrical connection protrusions are sharp teeth, but the connection is unstable due to the mechanical connection protrusions, so the electrical connection protrusions are flat couplers. It was necessary to break through the entire area, which was also difficult to work with.

[Purpose of the invention]

A first object of the invention is to provide a flat cable connector that provides reliable mechanical connection and, as a result, stable electrical connection.

In addition to the above objects, the second and third inventions also aim to improve connection workability.

[Disclosure of the invention]

The first invention includes a mechanical connection protrusion made of a cut-and-raised piece that can be divided into two divided protrusions by a cut for one mechanical connection;
Introducing and bending the surface-divided protrusions in mutually opposite directions 2
and a connection hole consisting of two reversely inclined inclined portions.

The second invention is a mechanical connection I'i which is the same as the first invention, and the electrical connection has a sharp tip shape and has a protrusion that penetrates the insulator of the flat cable and slightly breaks the conductor. A connection protrusion made of a cut-and-raised piece with a certain height is provided.

In the third invention, the mechanical connection is the same as the first invention, and for the electrical connection, an electrical connection protrusion cut and raised radially is provided.

Embodiment An embodiment of the present invention is shown in FIGS. 1 to 10.
. In the figure, reference numeral 1 denotes a connector, which is made of a single metal plate and has a pair of V-shaped holding parts 2 connected by a connecting piece 3. Two mechanical connection protrusions 5 are provided at the tips of one opposing piece portion 4 of both grips 2, and three electrical connection protrusions 6 are provided in the middle. The other opposing piece portion 7 is provided with two connection holes 8 into which the mechanical connection projections 5 fit, and three electrical connection projections 6' facing the electrical connection projections 6.

The mechanical connection protrusion 5 is made of a cut and raised piece, and is divided into two divided protrusions 5a by a notch in the center. Each divided protrusion 5a has a triangular tip. The connection hole 8 has two inclined portions 8a that are inclined in opposite directions,
8b, each inclined portion 8a, 8b has a divided projecting piece 5a.
can be bent in opposite directions, that is, like a split pin. The connection hole 8 is formed by punching. The electrical connection protrusion 6 consists of an annular protrusion that protrudes around the hole as shown in FIG.

The connection of the flat couple using this connector will be explained. A flat couple 10id is obtained by sandwiching and covering a plurality of band-shaped flat conductors 11 between two insulators 12. There is also one in which both assembly members 12 are integrally molded.

Connector insertion holes 13 are provided in the insulator 12 at a constant pitch between each conductor 11 and on both side edges. To connect two flat cables 10, each is connected using three connectors 1 as shown in FIG.

To explain the connection work, the opposing piece 4 of the connector 1 is inserted into the connector insertion hole 13 of the flat cable 1, the flat cable 1 is held between the opposing pieces 4 and 7, and bent in parallel using a crimping tool. As a result, each divided protrusion 5a of the mechanical connection protrusion 5 pierces through the entire flat cable 1 and connects the connection hole 8.
enters each inclined major portion 8a, 8b, and is guided by its inner surface and bent in mutually opposite directions. That is, it bends like a split pin. Therefore, the mechanical connecting protrusion 5 can prevent the opposing pieces 4 and 7 from opening. It's the neck, the electrical connection protrusions 6, 6
' is a flat cable that pierces through the insulator 12 of 10 and bites into the conductor 111C therein, thereby establishing electrical continuity between the conductor 11 and the connector l. Note that electrical continuity can also be obtained by the mechanical connection protrusion 5, but it only makes contact at the part where it breaks through the conductor 11, and if the thickness of the conductor body 11 becomes thinner, the electrical conductivity obtained here increases. sex is very small.

Although they are connected in this way, since the protrusions 5a on both sides of the mechanical connection protrusion 5 are bent in the opening direction, a strong bonding force is obtained, and both opposing pieces 4 and 7 can be easily opened. There is no.

Therefore, the electrical conductivity between the electrical connection protrusion 6, 6' and the flat cable 10 is also stable.

Figures 11 to M14 show the second embodiment.

In this example, the opposing piece portion 4 is provided with an electrical connection protrusion 14 made of a cut protrusion. The tip of the electrical connection protrusion 14 has a triangular shape. The protrusion height of the electrical connection protrusion 14 is such that when the mechanical connection protrusion 5 connects both opposing pieces 4 and 7, the tip of the electrical connection protrusion 14 reaches the insulation of the flat cable 10 as shown in FIG. body 12 =
It is formed in such a crystalline manner that it breaks Y and slightly pierces the conductor 11.

In this way, since the electrical connection protrusion 14 is a protrusion piece with a sharp tip, it is difficult to break through compared to the one using the annular electrical connection protrusions 6, 6 as in the first embodiment. Less force is required, improving workability. In addition, although the electrical connection protrusion 14 has a height of 42 degrees that slightly penetrates the conductive Ta body 11, sufficient conductivity is maintained because the mechanical connection by the mechanical connection protrusion 5 is reliable. be done. "In contact with the conductor 11": The surface VT is wide and the conductivity is good.

The rest is the same as the first embodiment.

Figures 15 to 18 show the third embodiment.

In this example, the electrical connection protrusions 15 provided on the opposing piece portion 4 are cut and raised in a radial manner. In this way, as in the second embodiment, the breaking force is small and workability is improved.-
Furthermore, since several electrical connection protrusions 15 are provided radially, the electrical connection is more reliable than in the second embodiment.

〔Effect of the invention〕

The flat cable connector of the present invention has the advantage that mechanical connection is reliable and, as a result, electrical connection is also inexpensive.

The second and third inventions also have the effect of making the connection work easier.

19 to 21 show a connector 1' as a proposed example of a flat cable connector. In this example, a mechanical connection protrusion 16 and an electrical connection protrusion J7 are each made of a cut and raised piece.
It has been established that 18 in FIG. 21 is a hole.

In the process of pressing this 'i''L using the crimping tool X-,
The corner of the electrical connection protrusion 17 cuts open the surface of the insulator 12 covering the conductor 11 of the flat cable 10,
It is peeled off with pressure, and then the connection is completed with the tip of the mechanical connection protrusion 16 caulked. As a result, due to the springiness of the electrical connection protrusion 17, current is always applied to the conductor 11 even if there is a slight positional deviation.
