DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connector.

[0002]

2. Description of the Related Art In recent years, in offices and the like, it has been widely practiced to have a double floor structure and arrange electrical connectors and the like on the lower floor.

[0003] As shown in FIG. 4, a plug terminal connection portion 71 for inserting and connecting a power plug of an OA device or the like is provided on the front surface as an electric connector disposed on the lower floor, and a VVF cable of VVF cable is provided on both side surfaces of a base end. An electric connector 70 provided with cable conductor connection portions 72, 72 for inserting and connecting conductors,

[0004] As shown in FIG. 7, a plug terminal connection portion 8 for inserting and connecting a power plug of an OA device or the like to the front and rear surfaces.
1 and an electric connector 80 in which a cable conductor connecting portion 83 for inserting and connecting a conductor of a VVF cable is juxtaposed in the width direction.

As shown in FIG. 8, a plurality of outlets 92 for inserting and connecting a power plug of an OA device or the like,
An electric connector in which the power supply line drawn into the case 91 is connected to the outlet 92 and the same polarity of the outlet 92 and the adjacent outlet 92 ′ are connected to each other by a feed line. 90 are known.

[0006]

However, a plug terminal connecting portion 71 for inserting and connecting a power plug of an OA device or the like is provided on the front surface, and a cable conductor connecting portion 72 for inserting and connecting a conductor of the VVF cable on both side surfaces of the base end. , 72 are provided on both sides of the base end of the electric connector 70 because the cable conductor connecting portions 72, 72 for inserting and connecting the conductors of the VVF cable are provided.
As shown in FIG. 5, when the electric connector 70 is installed in the straight portion of the wiring groove formed in the lower floor constituting the double floor, the conductor of the VVF cable drawn into the wiring groove cannot be connected. For this reason, the installation location is not limited to the position where the wiring groove crosses the cross as shown in FIG. 6, and since the electric connector 70 closes the wiring groove crossing the cross, it is necessary to bypass the other feed wiring. There was a problem that it had to be done.

A plug terminal connection portion 81 for inserting and connecting a power plug of an OA device or the like to the front and rear surfaces, and a VVF
In an electric connector 80 in which cable conductor connecting portions 83 for inserting and connecting cable conductors are arranged in the width direction, as shown in FIG. Since the blades 82 and 82 are provided in parallel in the width direction, the blade terminals are provided at predetermined intervals in the circumferential direction.
A dedicated plug 85 is used as shown in the figure to prevent the power plug of the A device or the like from being directly inserted and connected.
There were problems such as the need for an intermediate connector such as an intermediate adapter and a line connector.

Further, in an electrical connector 90 in which a plurality of outlets 92, 92 'for inserting and connecting a power plug of an OA device or the like are housed in a case 91, a plurality of outlets 92, 92' are housed. Not only is the cost increased because of the need for the case 91, but also the power supply line drawn into the case 91 is connected to the outlet 92, and the outlet 9 adjacent to the outlet 92 is connected.
Since the same poles of 2 'must be connected to each other by a feed line, there is a problem that assembly is troublesome and productivity is extremely low.

The present invention has been made in view of the above problems, and has as its object to provide an electrical connector excellent in workability and economy.

According to the present invention, there is provided a base 1 in which cable conductor connection terminal storage chambers 2 are arranged in a row and a blade receiving terminal storage chamber 7 is provided in parallel with the cable conductor connection terminal storage chamber 2.

A predetermined interval (JIS)
(Spaces according to the standard). This blade receiving terminal 18
A power plug (such as a standard flat-blade two-pole grounding plug according to JIS standard) such as an OA device or an OA tap is directly inserted and connected to the terminal. Therefore, since the power plugs such as the OA equipment and the OA tap are directly inserted into and connected to the blade receiving terminal 18, no intermediate connector such as an intermediate adapter or a line connector is required.

The plurality of cable conductor connection terminals 16 and the blade receiving terminals 18 constituting the composite terminal 15 are placed in the cable conductor connection terminal storage chambers 2 and the blade reception terminal storage chambers 7 arranged in a row on the base 1. Since it is stored in parallel, when installing the electrical connector of the present invention in the wiring groove carved on the lower floor of the double floor structure,
Since it can be installed at any position in the wiring groove and does not block the wiring groove crossing the cross, there is no need to detour other distribution lines. Further, even if it is necessary to install the wiring groove at a position where the wiring groove crosses, there is no problem in the installation.

Further, as described in claim 2, the composite terminal 1 housed in the blade receiving terminal housing chamber 7 provided in the base 1 is provided.
Blade receiving portion 1 formed by bending the blade receiving terminal 18 constituting 5
9 is provided with a dustproof cover 49 that can be opened and closed continuously and integrally with one side surface of a blade receiving cover 45 that is formed at predetermined intervals in the circumferential direction. An electrical accident such as a short circuit accident caused by dust that has been lost and has entered inside through the blade terminal insertion port 46 can be prevented very effectively.
