Description

Power outlet

The utility model relates to a power socket, in particular to a new power socket with a guiding bevel on the wiring hole of the terminal block, which can facilitate the wiring personnel to quickly insert the cable along the guiding oblique side and conveniently lock the cable.

Power outlets are usually mounted to the equipment or building structure and are slotted to provide a matching plug for connection to the power supply, and each country has standards for power plugs and outlets. Among them, for power sockets that provide more than 20 amps of power, based on factors such as wiring robustness and current transmission stability, the power leads and grounding conductors must be connected to the power outlet by means of locking screws to "lock the cable". safety regulations.

As shown in FIG. 5, a conventional high-power power socket 90 is generally used. The power socket 90 includes a socket body 91 and a socket cover 92 coupled to the front side of the socket body 91. The back side of the 91 is provided with three terminal blocks 93 for respectively connecting the power supply wires and the grounding wires (not shown in the drawings, hereinafter referred to as wires), and each of the terminal blocks 93 defines a wiring hole 931 for inserting the wires, and is provided. A locking screw 94 is pressed and locked to achieve the fixing effect of the locking wire. However, according to the experience of actual operation, since the power socket 90 is usually disposed at a corner of the building or close to the ground, the space for providing the installation operation is relatively narrow, and the connection hole 931 is limited to be parallel or perpendicular to the rear of the socket body 91. The surface of the board is only slightly larger than the wire diameter of the wire. It is inconvenient for the wiring personnel to insert the wire into the hole 931. It is often repeated several times to insert smoothly, which not only affects the efficiency of the installation operation, but also easily causes the wire. The problem of not being securely locked.

In addition, since the power socket 90 is usually disposed at a corner of the building or close to the ground, the existing general power socket 90 lacks a safety protection design at the power socket position, and not only children may be inserted with fingers or slender, sharp objects due to curiosity. The slot causes a dangerous problem such as a child's electric shock or a short-circuit of the electric wire, and foreign matter such as dust and water droplets easily intrude into the power socket 90 through the slot, thereby affecting the electrical conductivity, structural durability, and electrical safety of the power socket 90.

In order to solve the problem that the existing power socket has a power wire or a ground wire which is not easy to be inserted into the terminal hole, which easily affects the efficiency of the installation operation and whether the wire is securely locked, the main purpose of the present invention is to provide a guide hole for the terminal block. The beveled edge can facilitate the wiring personnel to quickly connect the oblique side and the new power socket for the cable lock. Further, in order to solve the problem that the power socket of the existing socket body lacks safety protection design, a further object of the present invention is to provide a new power socket with a safety gate behind the power socket of the socket cover.

The power socket provided by the present invention includes a socket body, and the rear side of the socket body is provided with three terminal blocks which are arranged in an inclined manner.

The power socket, wherein the wire lock assembly includes a pair of wire ferrules that are the wire holes, and a locking screw that is threadedly coupled to the wire ferrule and aligned with the operation hole.

The power socket further includes a socket cover coupled to the front cover of the socket body, and a plurality of safety gates disposed on the socket cover.

The power socket, wherein the socket cover is provided with more than one sliding slot on the rear side, and each of the safety gates includes a sliding shutter slidably disposed corresponding to the sliding slot, and One or more homing springs disposed on the sliding shutter corresponding to the sliding groove and elastically biased against the sliding shutter.

Compared with the prior art, the enhancements obtained by the technical means of the present invention include: 1. The terminal block of the present invention is protruded in a tilted manner on the rear plate surface of the socket body, and the connection holes and the locking screws are inclined. Provided, and at the open end of the wiring hole, there is a guiding oblique edge which is outwardly widened, so that the power wire and the grounding wire can easily penetrate the wiring hole along the guiding oblique edge, and conveniently lock the screw It is locked to greatly simplify the wiring work of the power socket and improve the efficiency of the installation operation. 2. This new type has a slidable safety gate in front of the power socket of the power socket, which can form a shielding protection when the power socket is not in use, which can make it difficult for children to put fingers or slender, sharp objects into the contact power slot. To avoid the risk of electric shock or wire short circuit damage, and to prevent foreign matter such as dust and water droplets from entering the power socket, effectively maintaining the electrical conductivity and power safety of the power socket.
