Abstract

The utility model discloses a three-phase three-wire multipurpose socket and plug. The socket is composed of a base, a socket cover, a fixing block, multiunit three-phase lock pins, a conductive plate, etc., and the plug is composed of a housing, a three-phase plug post base, a plug post, a hard wired block, etc. The multiunit three-phase lock pins of the socket and the three-phase plug post of the plug are arranged in-line, and the incoming line of the power supply is accessed by a connection bore at the side edge of the socket. The lock pins design adopting multiunit form, so multiple electric equipment can be used simultaneously. When reversing, the electric motor exchanges phrase sequence by the plug with rewiring, with simple and convenient operation, and has no effect on power utilization for neighbours. In addition, as copper do not be exposed, the utility model has high safety and reliability.

Description

Three-phase three-wire multipurpose socket and plug

The utility model relates to power connector, particularly phase three-wire three socket, plug.

The phase three-wire three socket of prior art, socket, following defective is arranged: 1. socket can only plug of adapted, i.e. power consumption equipment, and directivity is arranged, motor is as wanting commutation, must rewiring change phase sequence, not only troublesome poeration also will influence other user power utilization, particularly busy farming season, electricity consumption is concentrated, and causes the contradiction between the user easily; 2. power line is former exposes copper spare from socket base inlet wire, has the hidden danger of unsafe factor.

The purpose of this utility model is to overcome the defective of prior art and provides a kind of to society and can use a plurality of power consumption equipments and convenient, safe phase three-wire three multipurpose socket, the plug of commutation simultaneously.

Realize the purpose of this utility model, its scheme is as follows: on the socket of being made up of base, socket cover, lock pin, the many groups of design three-phase lock pin becomes in-line to be arranged in parallel, each organizes the public conductive plate that is provided with mutual series connection between the adjacent lock pin, formation can be used the socket of multiple devices simultaneously, and to change socket base inlet wire be the wiring hole inlet wire of side, improves fail safe, the convenience used.

Be made up of shell, three-phase inserting column seat, inserting column, link piece with the matching used plug of socket, the three-phase inserting column becomes in-line to arrange, and its spacing equates with the three-phase lock pin pitch match of socket.

This phase three-wire three multipurpose socket, plug are compared with known technology, it can use many power consumption equipments simultaneously, motor commutation must rewiring, as long as the plug tuning can reach transposing phase sequence purpose, and do not influence the electricity consumption between the neighboring user, avoid the entanglement that causes thus, because no copper spare exposes phenomenon, inlet wire is changed into side, has both improved fail safe, makes easy to operate again.Because it is little, in light weight that volume changes, and can save raw material 30-40%.

Do following describing in further detail by above-mentioned accompanying drawing embodiment.

The base (1) and the socket cover (2) of phase three-wire three multipurpose socket (seeing Fig. 1-4) are fixed as one by fixed block (12) and screw connector, many group three-phase lock pins (9) become in-line to be arranged in parallel and by screw on base (1), there is jack at the position of the corresponding lock pin of socket cover (2) (9), and each organizes the public conductive plate (8) that is provided with mutual series connection between the adjacent lock pin (9).The bottom outlet of base (1) is equipped with porcelain envelope (10), avoids copper spare to expose.The wiring hole of power line (11) is opened at socket cover (2) side.

Lock pin on the phase three-wire three multipurpose socket (9) is advisable with the 3-4 group, is applicable to 3-4 platform power consumption equipment.

The embedded then three-phase inserting column seat (6) of the shell (3) that becomes with the matching used plug of phase three-wire three multipurpose socket (seeing Fig. 5-6) two semi-involutions, the inserting column (7) that in-line is arranged is connected with link piece (4) by inserting column seat (6), between inserting column seat (6) and link piece (4) packing ring (5) is housed, the spacing between the three-phase inserting column (7) equates with three-phase lock pin (9) pitch match of socket.When needing the phase sequence conversion, as long as with the grafting of plug tuning, do not influence the neighboring user electricity consumption, needn't take rewiring apart, safety easy to use particularly is used in mobile occasion, and remarkable advantage is more arranged.

Claims

1, a kind of phase three-wire three multipurpose socket, base (1) and socket cover (2) are by fixed block (12) one that links to each other with connector, and three-phase lock pin (9) is fixed on the base (1), and there is jack at the position of the corresponding lock pin of socket cover (2) (9), it is characterized in that:

A. described three-phase lock pin (9) is arranged in parallel for many group in-lines;
