DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Each of the drawings shows an embodiment of the present invention. A relay connector of this embodiment is a first insulation integrally formed of an insulating material having a certain elasticity such as polyacetal resin. A housing 1 and a second insulating housing 2,
It is composed of eight contacts 3 which are inserted and fixed in the first insulating housing 1, and eight relay plug contacts 4 which are contacts which are inserted and fixed in the second insulating housing 2.

The first insulating housing 1 has eight openings 1A in the vertical direction corresponding to each contact 3 in FIG. The contact 3 is integrally formed of a conductive material having a spring property, and is mainly provided at an upper end portion thereof with a pressure contact connecting portion 3A for performing pressure contact connection with the covered electric wire 5, and an intermediate portion provided with the contact 3 for the first insulation. A locking fixing portion 3B for fixing to the housing 1 and a male contactor 3C which is provided at a lower end portion and engages with a female relay plug contact 4 of a second insulating housing 2 described later are provided.

The structure of the contact 3 will be described in detail. The pressure connection portion 3A extends upward from the front surface and the rear surface, respectively, when the left side of the locking and fixing portion 3B in FIG. 1 is the front surface. 3A is provided corresponding to the thickness of the core wire formed of the conductive material of the covered electric wire 5, and is provided with a groove 3D for making electrical contact between the core wire and the contact 3. The locking fixing portion 3B is the opening 1 of the first insulating housing 1.
A step for positioning by engaging with a step 1B provided in A and an opening 3E for engaging with a projection 1C provided in the opening 1A and biased inward of the opening 1A are provided. . The male contactor 3C is below the opening 1A, and projects to the joint portion 1D where the opening 1A is widely provided in order to connect with the second insulating housing 2.

The connection between the first insulating housing and the contact 3 is made by engaging the projecting portion 1C with the opening portion 3E, so that the contact 3 is removed by releasing the engagement of the projecting portion 1C. Therefore, the contact crimped with the covered electric wire 5 can also be attached to the first insulating housing. A stopper projection 1E is provided on the upper portion of the first insulating housing 1 to prevent the covered electric wire 5 received in the press-connecting connection portion 3A from coming off upward. Therefore, just by pushing the covered electric wire 5 into the groove 3D of the pressure connection section 3A of the contact 3, the covering of the covered electric wire 5 is broken in the groove 3A and the core wire is supported, so that the contact 3 and the core wire of the covered electric wire 5 are electrically connected. And the projecting portion 1E prevents the covered electric wire 5 from coming off upward. Further, an engaging portion 1F that engages with a locking piece 2D described later is provided on the outer side of the lower portion of the first insulating housing 1.

The second insulating housing 2 has the joint portion 1D.
The first insulating housing 1 and the second insulating housing 2 are coupled by providing a plurality of convex portions 2A corresponding to the above and inserting the convex portions 2A into the joint portion 1D. Further, the engaging portion 1
Locking piece 2 for preventing the first insulating housing 1 and the second insulating housing 2 from coming off by being inserted into F and locked.
D is arranged from the lower part of the outside toward the upper side.

The convex portion 2A of the second insulating housing 2 is provided with an opening 2B in the vertical direction in FIG. 1 corresponding to the male contact 3C, and the relay plug contact 4 is arranged in the opening 2B. It is set up. The relay plug contact 4 is provided in the opening 2B, into which the male contactor 3C can be inserted, and the male contactor 3C is pressed by the urging portion 4A to electrically contact the relay plug contact 4. In addition, the relay plug contact 4 is provided with an opening 4B that engages with the projection 2C that is biased inward of the opening 2B, and the projection 2C is inserted into the opening 4B, whereby the second insulating housing 2 is inserted.
And the covered electric wire 5 is connected to the lower end by crimping.

Explaining the wiring using the above-mentioned connector for relay connection, first, the covered wire 5 is positioned above the protruding portion 1E of the first insulating housing 1 for preventing the wire from being pulled out, and the covered electric wire 5 is pushed in. Above the protruding portion 1E. Since it is inclined, it can be inserted smoothly, but the lower part has a reverse taper shape, which prevents the covered electric wire 5 from coming off. Then, in the covered electric wire 5 pushed below the protruding portion 1E, the covering is pressure-bonded connection portion 3
The core wire is broken by A and the core wire comes into contact with the press-connecting connection portion 3A, so that the core wire and the press-connecting connection portion 3A are electrically contacted.

Since the electrical contact between the core wire and the press-connecting connection portion 3A can be performed only by sandwiching the covered electric wire 5 in the first insulating housing 1, it can be easily performed by a machine. Next, by connecting the relay plug contact 4 to which the covered electric wire 5 is crimped and connected to the second insulating housing 2, and inserting the convex portion 2A of the second insulating housing 2 into the joint portion 1D of the first insulating housing 1, The male contactor 3C existing inside the joint portion 1D is inserted into the relay plug contact 4 in the second insulating housing 2. The male contactor 3C inserted in the relay plug contact 4 is urged by the urging portion 4A to come into contact with the relay plug contact 4.

The first insulating housing 1 and the second insulating housing 2 are locked by inserting a locking piece 2D provided on the second insulating housing 2 into an engaging portion 1F provided on the first insulating housing 1. It is fixed by. First insulating housing 1
The second insulating housing 2 can be easily separated from the second insulating housing 2 by pushing down the locking piece 2D to release the locking with the engaging portion 1F and then pulling it out.

[0015]

As described above, according to the present invention, the connection with the covered electric wire which is through-connected can be easily attached and detached. Therefore, when the branched electric wire is removed, the first insulating housing and the second insulating housing can be separated from each other to facilitate the operation. It can be removed.
