Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a connector used for connecting a multi-core cable.

[Conventional technology]

FIG. 5 shows a conventional structure of a connector used for connecting a multi-core cable.

The connector 1 is composed of a body 2 and a cover 3 which are detachably connected to each other. The body 2 and the cover 3 have a rod 3a provided on the cover 3 side inserted into an insertion hole 2a on the body 2 side. By doing so, they are joined together.

The body 2 is composed of a lower member 2b and an upper member 2c that covers the lower member 2b. The lower member 2b
Are provided with a large number of contacts 4, and the contacts 4 are arranged in two rows in a staggered manner. Further, these contacts 4 are formed of a conductor such as a metal, and in a state where the upper and lower members 2b and 2c are integrated with each other, the contacts 4 penetrate the upper member 2c and are projected from the upper portion thereof. A slit 4a is formed in the contact 4, and a core wire of the cable (not shown in FIG. 5) is inserted into the slit 4a, and a pressing member (not shown) provided on the lower surface of the cover 3 is inserted. The core wire is electrically connected to the electrode 5 integrated with the contact 4 by pressing the core wire into the slit 4a of the contact 4 by using.

By the way, in the conventional connector, in order to surely guide the core wire to the slit 4a of the contact 4, the following consideration is given to the body.

That is, as shown in FIG. 6, inclined portions 6 toward the contact 4 are formed in the bodies 2 on both sides of the contact 4,
Alternatively, as shown in FIG. 7, bent portions 7 are formed, and the core wires 9 are set so as to be in contact with the inclined portions 6 or the bent portions 7, whereby the pressing member on the lower surface of the cover 3 is pressed. When the cord 8 presses the cord 7, the cord 9 is guided along the inclined portion 5 or the bent portion 6 to the contact 4 while sliding.

[Problems to be solved by the invention]

However, since the core wire 9 of the multi-core cable is generally formed into a cable in a twisted state, so-called "twisting" is attached, and the core wire 9 is once placed at a predetermined position (a position near the inclined portion 5 of the body 2). Even if it is set, it may be disengaged from the inclined portion 6 or the bent portion 7 due to this twisting. In such a case, the core wire 9 may not be set at a predetermined position even if the cover 3 is attached.

In addition, there is a problem in that the work efficiency becomes extremely poor if it is attempted to set it at a predetermined position while removing the twisting behavior of a large number of core wires 9.

The present invention has been proposed in view of the above circumstances, and an object thereof is to provide a connector capable of reliably and efficiently attaching a core wire to a contact.

[Means for solving problems]

In order to solve the above-mentioned object, the present invention provides a connector base in which a plurality of contacts each having a slit at one end are planted at a constant pitch with respect to the surface of the body, and pressing the surface of the connector base. With a fixed cover,
In this cover, a pressing member having a sloping surface extending from the bottom surface is integrally formed, ridges and valleys are alternately formed by the sloping surface, and the pitch of the valleys corresponds to the pitch of the contacts. When the cover is pressed and fixed to the surface of the connector base, the cores of the cable, which are arranged in advance in the vicinity of the slit of the contact, are gathered in the valleys, and the valleys remain as they are. A multi-core cable connector configured to press each core wire and insert each core wire into a slit of each contact.

[Action]

After arranging the cable cores near the slits of the contacts that are planted over the surface of the body, press and fix the cover on the surface of the connector base. The wires are gathered in the valleys of the pressing member, and the valleys press the core wires as they are, and the core wires are inserted into the slits of the contacts.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. In the figure, the same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

1 to 4 show an example of the present invention. In the connector of the present invention, a plurality of contacts 4 each having a slit 4a at one end are planted on the surface of the body 2 at a constant pitch. And a cover 3 that is pressed and fixed to the surface of the connector base.

On the bottom surface of the cover 3, a pressing member 10 is integrally formed by extending a part of the bottom surface. Further, as shown in FIG. 1, the pressing member 10 is provided with a notch in which a ridge portion 10b and a valley portion 10c are alternately formed in a serrated shape by an inclined surface 10a to receive each core wire of the cable. The pitch of the valleys 10c is provided to be substantially equal to the pitch of the contact slits 4a. What is important here is that the inclination angle of the inclined surface 10a changes drastically at the peaks 10b and the valleys 10c, and both the peaks and the valleys form one ridge line, which is used for connector connection. That is, there is no plane portion orthogonal to the pressing direction.

In the connector configured as described above, the core wire 9 between the body 2 and the cover 3 is arranged as shown in FIG. 1, and in this state, the cover 3 is attached to the body 3 as shown in FIG. The core wire 9 is guided so as to always come into contact with one of the inclined surfaces 10a when it is pressed against 2, and then slides along the inclination of the inclined surface 10a to be positioned in the slit 4a of the contact 4. To be done. Then, by pushing the cover 3 further downward from the state shown in FIG.
Is inserted into the slit 4a by the valley 10c, the contact 4 breaks the coating 9a and comes into direct contact with the conductor 9b, and the cover 3 is joined to the body 2.

[Effect of device]

According to this invention, a connector base is formed by arranging a large number of contacts having slits at one end on the surface of the body at a constant pitch, and a cover pressed and fixed to the surface of the connector base. This cover is provided with a pressing member that extends from the bottom surface of the cover and has an inclined surface and is integrally formed with the inclined surface so that peaks and valleys are alternately and continuously formed, and the pitch of the valleys is small. When the cover is pressed and fixed on the surface of the connector base, each core wire of the cable, which is arranged in advance in the vicinity of the slit of the contact, is always an inclined surface. Guides to collect in the troughs, and the troughs are configured to press each core wire as it is and insert each core wire into the slit of each contact. (I) Connect the cover The cable core that is arranged near the slit and bent can be inserted into the slit at once by simply attaching it to the base. (Ii) The pressing member and cover can be integrally molded by plastic molding. (Iii) Since the valley portion itself does not receive the core wire, there is an effect that the pressing amount of the cover is constant and a small amount is required.
