  2. Description of the Related Art Conventionally, a wire relay plug and a wire relay connector for connecting and energizing wires to each other are well known, and a wide variety of shapes have already been manufactured and used. As these electric wire relay plugs and connectors, there are known connectors used for energizing minute and fine electric wires, such as communication cables, from energizing cable connectors for household electric appliances.

  Further, a plug and a connector that can be electrically connected by fitting two connector plugs to each other with the left and right and the top and bottom being reversed are already known (Patent Document 1). , 2).

JP 2012-129125 A Japanese Utility Model Publication No. 3-127780

  In the former Patent Document 1 which published the prior art previously developed by the applicant of the present application, a joint connector of a pressure connection system that is connected to an electric wire by a U-shaped metal fitting having a pressure contact groove is shown. Consists of a plug molded with a single good conductor metal plate and an insulating resin housing that covers the plug. It is assumed that the middle part has a retaining protrusion that engages with the housing, and the contact plug part on the tip side. The U-shaped parallel wall and the lower half wall of the tip side part of the plug part are cut out. A structure is shown in which two projecting walls with only half walls are used, and when the connectors are energized, the two projecting walls and the parallel wall are in contact with each other and energized. A wire connection plug having a hermaphroditic structure in which an electrical connection is made by inserting the plugs in the housing in a state in which the two connectors are inserted in the opposite directions upside down and left and right is shown.

  Therefore, the connector having the structure described above has a structure in which the plug portion is not complicated and can be easily manufactured. However, since the connection with the electric wire is a press-contact connection structure, the target electric wire is a covered electric wire. Thus, the connection is limited to that of the pressure connection method, and there is a problem that it cannot be used other than a connector that uses a covered electric wire as a target.

The sliding blade that is moved back and forth by the operation of the slide button connected to the blade holding member is slidably held, and the lower blade receiving spring is a blade receiving member that is electrically connected when the other sliding blade is inserted. The upper sliding blade is a male terminal on the insertion side and the lower blade receiving spring is a female terminal for receiving the male terminal. These sliding blade and blade receiving spring are the sliding blades. In this structure, the holding member is electrically connected by a sliding operation. Further, this connector is provided with a lock and guide member separately from the above-mentioned connection member for electrical connection, and is engaged with a locking piece provided on the slide button to prevent the connectors from coming off. It has a structure that fulfills its function.

  Therefore, the connector having the structure described above has a problem that the entire connector has a large number of parts and the structure is complicated, and it takes time to manufacture and assemble each part, resulting in high costs. Yes.

When the two housings 8a and 8b are connected to each other in this way, the plugs 1 and 1 inserted into the respective housings have the posture shown in FIG. 9, and the two housings as shown in FIG. The opposing surfaces of the respective extension walls 46 and 46 are in contact with each other in 8a and 8b, and are connected in a state where energization is possible.

  Further, as shown in FIGS. 14 to 16, the left and right housings 8, 8 are engaged with each other by engagement between a gate-shaped engagement body 83 and a protrusion-type locking body 84 fitted therein. Once engaged, the engagement state is maintained unless the engagement is positively released.

  The size of the plug 1 shown in the present embodiment is of a property that can be formed in various sizes depending on the wire diameter of the covered electric wire to be connected and the required energization amount. The plug 1 shown can be implemented with a left-right length of 30 to 35 mm and a housing 8 shown in FIGS. 10 and 11 having a left-right length of about 75 to 80 mm.

A wall portion corresponding to the bent portion 45 is deformed into a V-shape, and an extended wall 46 portion extending from the V-shaped bent portion 45 toward the second wall 43 side is closer to the extended end side. It is inclined so as to approach the second wall 43 side.

  As shown in FIG. 19, the two plugs 10 and 10 having the extended wall 46 portion as the inclined wall structure are arranged by changing the direction as in the case of the first embodiment, and further shown in FIG. As described above, energization is performed by directly contacting the opposing surfaces of the inclined extension walls 46 and 46 of the two plugs 10 and 10.

  In the plug 10 shown in the embodiment, the inclined extension walls 46 and 46 that follow the bent portion 45 can be easily brought into direct contact with each other, and can be energized while the contact surface is in a pressure contact state. And it has the advantage that it can energize reliably.

  Although the embodiment considered to be representative of the present invention has been described above, the present invention fulfills the above-described configuration requirements, achieves the above-mentioned object, and implements it with appropriate modifications within the scope of the above-mentioned effects. It is something that can be done.

  Since the plug 1 according to the present invention and the pair of housings 8 and 8 which are insulated by embedding the plug 1 need only be pressed and connected, the connection between the wires can be completed very easily by almost one-touch operation. Can be used in the market.
