The ground connection plate 27 is formed of a metal plate, The grounding clip 18 and the grounding connecting plate 27 are energized by fastening the long screw 28 to the grounding clip 18 by sandwiching the long screw 28 with the fixing table 24 and the outer cover 19.

The grounding terminal is thus divided into a grounding clip (hereinafter collectively referred to as a grounding pin) and a grounding plate because, in very particular cases, most of the recessed receptacles are provided with two or more sockets, The grounding pins are spaced apart from each other so as to be exposed, so that they can be connected to one current-carrying structure.

However, if the ground terminal is divided into the ground pin and the ground connection plate as in the prior art, the number of parts to be used is increased according to the number of the sockets, so that it is necessary to screw each ground pin and the ground connection plate Therefore, if the strength of the threaded connection is lowered, the power supply to the ground pin and the ground connection plate are cut off and the grounding is not performed, thereby causing a safety accident.

Accordingly, the present invention has been made to solve the above-mentioned problems,

Next, the wire connecting means 60 is embedded in the second mounting portion 51 (more strictly, the first mounting groove 51A) and the receiving portion 52, and is inserted into the second mounting portion 51 A spring terminal 61 and a separating member 62 that allow energization and separation of the power supply line and the ground line sandwiched in the accommodating portion 52 to the connecting portion 43 and the grounding portions 23A and 23B, .

The wire connecting means 60 incorporated in the accommodating portion 52 will be specifically described.

The spring terminal 61 is connected to the grounding line of the second grounding portion 23B of the grounding terminal 20 (the second body portion 41 in the case of the connection terminal 40) to be inserted into the fitting holes 51a and 52a The spring terminal 61 and the first ground portion 23A (the connection portion 43 in the case of the connection terminal 40) are forcibly brought into contact with each other by electrical connection via the conductive wire, A contact portion 61a elastically supported in the direction of the long first ground portion 23A (connection portion 43 in the case of the connection terminal 40) is provided so that the ground line (connection terminal 40), the conductive wire of the power supply line is electrically connected to the end of the contact portion 61a.

The spring terminal 61 is formed by bending a conductive metallic material into a zigzag shape that is inclined forward and backward to one side so that a contact portion 61a as a rear side end portion connected upwardly inward is inserted into the fitting hole 51a, And a support portion 61b which is connected to the front side end portion by being bent to one side while being in contact with the second ground portion 23B (the second body portion 41 in the case of the connection terminal 40) The support portion 61b is supported on the protruding portion 31a of the intermediate body 30 (the back surface of the connection portion 44 in the case of the connection terminal 40).

The support portion 61b prevents the spring terminal 61 from collapsing when the spring terminal 61 is housed in the receiving portion 52 and prevents the spring portion 61b of the support portion 61b Contacts the connecting portion 44 to further strengthen the energizing structure.

The separating member 62 is slidably coupled to the receiving portion 52 (the second mounting groove 51B in the case of the connection terminal 40) so as to be drawn out so as to have an inclination angle corresponding to the inclination of the contacting portion 61a And a pressing portion 62a formed on the contact portion 61a to contact the contact portion 61a so that the pressing portion 62a presses the contact portion 61a in a direction opposite to the tentering direction when the contact portion 61a is drawn, Unlock the wire.

The separating member 62 is engaged with the pressing holes 51b and 52b such that the separating member 62 is movable forward and backward from one side of the fitting holes 51a and 52a and is operatively connected to the pressing holes 51b and 52b, The projection 62b is slidably engaged with the guide groove 53a and the rear end is exposed by the pressing holes 51b and 52b,

The pressing portion 62a is provided on both left and right sides so that the pressing portion 62a is urged by the contact portion 61a to be pushed toward the rear side of the rear body 50. The separating member 62 is urged by a separate external force So that it is pushed out to the rear side.

The separation preventing member 62c protrudes from the upper and lower surfaces of the separating member 62 so that the separation preventing member 62c is caught by the stepped portion of the rear body 50, 61 to the rear side of the press-in holes 51b, 52b.

Therefore, when the conductive wire of the ground wire (or the power line) is inserted into each of the fitting holes 51a and 52a, the conductive wire contacts the space portion between the contact portion 61a and the first ground portion 23A H, the contact portion 61a, which is elastically supported in the direction of the fitting holes 51a, 52a, is bent in a direction opposite to the torsion spring. After the conductive wire is fastened, the contact portion 61a is retracted The end of the contact portion 61a is fixed to the outer circumferential surface of the conductive wire to fix the conductive wire,

This conductive wire is electrically connected to the ground terminal 20 (or the connection terminal 40) and the ground wire (or power source) as the physical contact with the first ground portion 23A (or the connection portion 43) (Energized) between the spring terminal 61 and the ground terminal (or line) and the spring terminal 61 are made to ground (or power supply).

When the grounding line (or the power line) needs to be separated from the recessed socket for replacement of the recessed socket, the separating member 62 is pulled forward using the pushing holes 51b and 52b The pushing portion 62a of the incoming separating member 62 pushes the contact portion 61a back inward in the direction opposite to the tentering so that the contact portion 61a is spaced apart from the outer circumferential surface of the conductive wire, The conductive wire is easily separated from the fitting holes 51a and 52a when the ground wire (power line) is removed.

On the other hand, an electric wire coated with a bundle-type electric wire strand may be used instead of a single-type conductive wire depending on the structure. In this case, the energization connection through the wire connection means 60 may not be securely maintained. When the wire connecting means 60 can not be used, the electric wire is directly connected to the fixing hole 21b or the bent portion 24 of the ground terminal 20 through the connection hole 36 or the exposed portion 35, Can be achieved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. And should be construed as falling within the scope of protection of the present invention.
