At this time, when the protective cover 30 is viewed from the top of the socket body 10 while being coupled by the fixing means 40 so as to cover the connection terminal portion 14 of the socket body 10, Since the auxiliary inner groove 38 of the cover 30 is aligned with the auxiliary hook groove 18G of the socket body 10 so as to be vertically aligned with the socket body 10 The auxiliary hook piece 28 at the lower end of the hook 20 is inserted into the auxiliary hook groove 18G of the socket body 10 through the auxiliary inner groove 38 of the protective cover 30 Can be inserted.

The hook 20 is lowered from the socket body 10 so that the lower end of the hook 20 and the auxiliary hook piece 28 are connected to the socket body 10 without having to lift the protective cover 30 from above the socket body 10. [ It is possible to engage the hook 20 for supporting the relay 2 with the socket body 10 more quickly and conveniently because the hook 20 can be coupled to the hook body groove 18 and the auxiliary hook groove 18G of the relay body 2 .

In the second embodiment of the present invention, the bottom surface of the second end cover portion 30B of the protective cover 30 is provided with a wire guide recess, which is spaced apart from each connection terminal portion 14 of the socket body 10, Respectively. The wire guide groove is formed by a wire guide projection (EP) formed so as to protrude next to the hole. See FIGS. 32 and 33.

The electric wire connected to the second terminal connecting terminal portion 14B of the socket body 10 is electrically connected to the electric wire formed by the electric wire guide protrusion EP on the bottom surface of the second end cover portion 30B of the protective cover 30, The electric wires connected to the second end connection terminal portion 14B of the socket body 10 are laterally offset without covering the first end connection terminal portion 14A so that the protective cover 30 The tool is caught by the upper wire, that is, the wire connected to the second-stage connection terminal portion 14B, or is caught by the wire, and the lower portion of the lower end The first end connecting terminal portion 14A is prevented from being invisible so that it is inserted under the tool through the hole of the first end cover portion 30A of the protective cover 30 so that the first end connecting terminal portion 14A The operation of tightening the wire connection bolt 14BT can be performed without interruption. In other words, since it is prevented that the upper electric wire connected to the socket body 10 is hidden from the lower connection terminal portion 14, it is possible to prevent the worker from being disturbed in the operation of connecting the electric wire to the lower first end connection terminal portion 14A There is no work. Furthermore, it is also possible to prevent a short circuit between the upper wire and the lower wire.

≪ Third Embodiment >

In the case of the third embodiment of the present invention, most of the constitutions are similar in comparison with the second embodiment. However, in the case of the third embodiment, the relay cover 12 of the socket body 10 is formed in a circular shape, and the second end cover portion 30B of the protective cover 30 is provided with a columnar line portion, And a circumferential line portion formed in the second end cover portion 30B of the protection cover 30 is fitted to the socket body 10 in such a manner as to fit into the outer circumferential surface of the relay engagement portion 12. [ The second stage cover portion 30B protects the entire upper surface of the socket body 10 except for the relay engaging portion 12 so that a tool such as a driver touches the connection terminal portion 14 to generate an electric shock or short- Can be more reliably prevented. The socket body 10 according to the third embodiment is provided with a hook groove 18 so that the lower end of the hook 20 is engaged with the hook groove 18 of the socket body 10 and the hook 20 The hooking locking piece of the socket body 10 is hooked on the hooking bridge piece 19 provided on the side of the hooking groove 20 of the socket body 10 so that the hooking hook 20 is prevented from being pulled up from the socket body 10 do.
