[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact for electrically connecting electric wires, and more particularly to a contact capable of slidingly connecting contacts of the same shape. Furthermore, the present invention relates to a connector device provided with such a contact.

[0002]

2. Description of the Related Art Electrical contacts of the type which can connect contacts of the same shape without distinction between male and female types can be obtained by simplifying the manufacturing process by unifying molds and reducing the number of component types in connection work. Since it has advantages such as easy management and handling, it has been conventionally developed and used in various fields.

[0003] An example of such a conventional hermaphroditic contact is disclosed in Japanese Utility Model Laid-Open Publication No. 61-19975.
The contact is formed from a sheet metal material through a punching and bending process, and has a first conductive contact portion at one end for sliding contact with a mating contact, and a second conductive contact for connecting an electric wire to the other end on the opposite side. It has a contact part. In the first conductive contact portion,
Through a pair of cuts extending in the longitudinal direction of the contact, a central contact piece arranged on one plane, and both sides arranged on a plane parallel to the central contact piece and on a different plane from the central contact piece A contact piece is formed. The second conductive contact portion is connected to the first conductive contact portion such that its plate surface is substantially perpendicular to the plate surface of each contact piece of the first conductive contact portion.

[0004] The second conductive contact portion has an open slit extending linearly in the longitudinal direction of the contact and opened at the outer peripheral edge of the second conductive contact portion. The open slit extends in a direction substantially perpendicular to the plate surface of each contact piece of the first conductive contact portion. The second conductive contact portion is configured such that an insulated wire, that is, a cable is press-fitted into the open slit, so that the inner peripheral edge portion of the second conductive contact portion that defines the slit pierces the sheath and the insulator of the cable and contacts the conductive wire. Having. Such a press-fit connection method is generally referred to as “press-contact”. On the other hand, a method of caulking the conductive contact portion of the contact to the conductor exposed by removing the sheath and the insulator at the end of the cable in advance is generally called "crimping".

When a pair of contacts of the same shape having the above structure are connected to each other, each of the first conductive contact portions is moved from its free end with one of the contacts being inverted with respect to the other contact. Mating plug-in each other. At this time,
The central contact pieces and the two-side contact pieces of the first conductive contact portion of both contacts are arranged so as to overlap with each other, and the central contact pieces make conductive contact with each other on their plate surfaces. The center contact piece of the other contact is pinched and conductively contacted at their edges. When the coupling is complete, the second conductive contact of one contact is located on the opposite side of the second conductive contact of the other contact with respect to the interconnected first conductive contact.

The partial correction structure of the contact is disclosed in
-19976. This contact is
It has a first conductive contact and a second conductive contact similar to the contact, but the relative arrangement of the conductive contact is different from the contact. In other words, in this contact, the plate surface of the second conductive contact portion is substantially perpendicular to the plate surface of each contact piece of the first conductive contact portion, and the open slit of the second conductive contact portion is formed by the first conductive contact portion. The two conductive contact portions are connected to each other so as to extend substantially parallel to the plate surface of each contact piece and to the side of the first conductive contact portion. When a pair of contacts having such a structure are connected to each other in the same manner as the above-mentioned contacts, the second conductive contact portion of one contact is related to the mutually coupled first conductive contact portion, and the second conductive contact portion of the other contact is It is arranged on the same side as the second conductive contact portion to face.

[0007]

In the above-mentioned conventional contact, the structure of the first conductive contact portion is relatively complicated, and high molding is required to maintain a stable connection state with the counter contact. There is a problem that requires accuracy.

Opposite to each other with respect to the coupled first conductive contacts. Therefore, when a pair of connectors incorporating such contacts are fitted to each other in a state where the cables are connected to each other, the cables connected to each connector are displaced in parallel with each other. As a result, the installation space of the mated connector device is unnecessarily expanded, and the handling of the cable wiring is affected, and depending on the connector installation location, the connection becomes difficult or the wiring must be reassembled. There is.

On the other hand, in the conventional contact disclosed in Japanese Utility Model Laid-Open No. 61-19776, when a pair of contacts having the same shape are connected, the second contact of the two contacts is connected as described above.
Since the conductive contacts are arranged on the same side of each other with respect to the interconnected first conductive contacts, the problem with cabling is substantially solved. However, this contact has a form in which the open slit of the second conductive contact portion is extended substantially parallel to the plate surface of each contact piece of the first conductive contact portion and to the side of the first conductive contact portion. The dimensions of a single connector incorporating this contact become particularly large in the height direction, that is, in the direction orthogonal to the connected cable. As a result, there arises a problem that the installation space of the mutually fitted connector devices is unnecessarily enlarged.

An object of the present invention is to provide a contact capable of slidably connecting contacts having the same shape, which is easy to manufacture, and the wires connected to each contact are arranged substantially coaxially after the sliding connection. An object of the present invention is to provide a contact that can be made and that does not hinder miniaturization of a connector having the contact. Another object of the present invention is to provide a connector device which is composed of a pair of connectors having the external shape of a hermaphroditic body incorporating such a contact, and which can prevent the installation space from being unnecessarily expanded in a mutually fitted state. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings. 1 to 3 show a contact 10 for connecting an electric wire according to an embodiment of the present invention. The contact 10 has a shape extending long in one direction as a whole, and has a first conductive contact portion 12 at one end for sliding contact with a mating contact, and connects an electric wire to the other end on the opposite side. A second conductive contact portion; The contact 10 is integrally formed from a sheet metal material through a punching and bending process.

The first conductive contact portion 12 of the contact 10 is a substantially flat plate-like element, and a first slit 16 is provided along a center line extending in the longitudinal direction of the contact 10. First
The slit 16 is formed as an open slit which is opened at one longitudinal end of the contact 10 to the outer peripheral edge of the first conductive contact portion 12, and a contact for slidingly inserting a mating contact at the open end. A child insertion port 18 is defined. Inner peripheral edge portion 1 of first conductive contact portion 12 defining first slit 16
2a extends in a curved manner from the contact insertion port 18 in an arc shape, forms a sliding contact area 20 facing the contact insertion opening 18 via a minimum slit width, and further expands into a U-shape. Extends to define a bottom region 22 of maximum slit width. The minimum slit width in the sliding contact area 20 is substantially equal to, or preferably slightly smaller than, the plate thickness of the first conductive contact portion 12 of the contact 10.

The second conductive contact portion 14 of the contact 10 is a substantially flat plate-like element, and a second slit 24 is provided along a center line extending in the longitudinal direction of the contact 10.
The second slit 24 is formed as an open slit which is opened to the outer peripheral edge of the second conductive contact portion 14 at the other end in the longitudinal direction of the contact 10, and a wire pressure inlet 26 for press-fitting a cable into the open end. Is defined. The inner peripheral edge portion 14 a of the second conductive contact portion 14 that defines the second slit 24 extends linearly from the wire pressure inlet 26 to the U-shaped bottom region 28, and extends over substantially the entire length of the slit 24. Thus, the slit width is equal to or preferably slightly smaller than the diameter of the corresponding electric wire or cable core.
Thus, the second slit 24 functions as a slit for cable pressure welding.

As shown in FIG. 2, the first conductive contact portion 12 and the second conductive contact portion 14 are integrally connected via a connecting portion 30, which is an L-shaped plate element. The connecting portion 30 includes an upright portion 32 that is connected to the first conductive contact portion 12 substantially orthogonally.
And a substrate portion 34 that is connected to both the upright portion 32 and the second conductive contact portion 14 at substantially right angles. Therefore, the first conductive contact portion 12 and the second conductive contact portion 14 are disposed orthogonal to each other, and the second conductive contact portion 14 and the upright portion 32 are disposed substantially parallel to each other.

The first conductive contact portion 12 is disposed on the same side as the second conductive contact portion 14 with respect to the substrate portion 34 of the connecting portion 30 and substantially extends in the direction in which the first slit 16 of the first conductive contact portion 12 extends. The second conductive contact portion 14

As shown in FIG. 4, the contact pair 36 is composed of two contacts 10 of the same shape and the same size coupled to each other at the respective first conductive contact portions 12. In the contact pair 36 in which the connection has been completed, the plate surfaces 12a of the first conductive contact portions 12 of both contacts 10 are arranged at an angle of approximately 90 °, and the slit of one of the first conductive contact portions 12 is formed. 16

As a result, both first conductive contact portions 12 are arranged such that their plate surfaces 12a form an angle of approximately 90 °.

In this position, the contact insertion openings 18 of the first conductive contact portions 12 of both the contacts 10 abut each other, and the first conductive contact portions 12 are inserted into the respective slits 16 while sliding each other. At this time, due to the plate thickness and rigidity of the contact 10, both first conductive contact portions 12 are separated from their plate surfaces 12.
a is maintained in a posture forming an angle of about 90 °. Next, the contact insertion slot 1 of the slit 16 of one contact 10
When 8 passes through the bottom region 22 of the slit 16 of the other contact 10, the pair of sliding contact regions 20 of both slits 16 begin to make sliding contact with the front and back plate surfaces 12 a of the first conductive contact portion 12 of the other party. Then, at a predetermined position (for example, the first conductive contact portion 1)
