Abstract
The utility model relates to a three-phase four-pole plug used for AC moving power station, which comprises a shell body; one end of the shell body is screwed with an wire outlet base, and a press piece can be arranged on the wire outlet base to fix a cable; the other end of the shell body is screwed with a plug body, and the plug body is screwed with a thread cover to assemble a connecting sleeve connected to a plug cover to the plug body, and four plug pins are fixed in an isolator and placed in the middle of the plug body. The jacks of the three-phase four-pole socket matching the three-phase four-pole plug is fixed in the isolator and placed in the plug body altogether, and a socket cover is locked to one end of a socket body. The utility model greatly modifies the present plug and socket, and is characterized by more reliable working, more convenient using, safety, good shock resistance, rain-snow leakage resistance, etc., and can be reliably used in poor indoor and outdoor working environments. The utility model is suitable for electric connection of AC (alternative current) power frequency and cable load of medium frequency power station, and the cable connection can not only be welded but also be press welded.
Description
Technical field
The utility model belongs to a kind of electric component, and a kind of specifically mobile power station cable that exchanges connects used three-phase and quadrupole plug and socket.
Background technology
Existing its housing of three-phase and quadrupole plug is an integral type, and contact pin directly is fixed in the housing, can only adopt the method for perfusion scolding tin during stube cable, and is time-consuming cumbersome.
Summary of the invention
The utility model purpose provides a kind of three-phase and quadrupole plug and socket that can weld and can crimping.Specifically, a kind of used three-phase and quadrupole plug of mobile power station that exchanges, has housing (3), housing (3) one ends are connected with outlet seat (4), the compressing tablet (18) that is used for fixing cable is housed on the outlet seat (4), it is characterized in that being connected with plug body (1) at housing (3) other end, be installed with thread bush (8) on the plug body (1), the adapter sleeve (6) of being convenient to be connected with bayonet cap (2) is loaded on the plug body (1), and four contact pins (14) are fixed in the insulator (17) and place together in the middle of the plug body (1).
Be shaped on the hangnail (20) that prevents its slippage displacement on the contact pin (14).When contact pin inserted pin holes in the collets, relying on hangnail on it that it is clamped in the collets can not withdraw from or be shifted, and fixing-stable is reliable.
As a whole of the insulator of fixing plug pin, two dock insulator good stabilities of comparing general, contact point is better.
In the outlet of outlet seat (4), has only sealing ring (5).In the endoporus that housing end of incoming cables and outlet seated connection touch, be equipped with rubber blanket (11) and packing ring (12).Be equipped with sealing ring (10) and rubber blanket (13) respectively at plug body (1) two ends and housing (3) and bayonet cap (2) contact position.The increase of aforementioned these block rubbers and sealing gasket has improved the waterproof and the antifouling property of plug, is more suitable for the use of wild environment.
With the matching used a kind of used three-phase and quadrupole socket of mobile power station that exchanges of aforementioned plug, its jack (22) is fixed in the insulator (21) and places together in the socket (24), and socket cover (27) is connected to an end of socket.
Be shaped on the hangnail (210) that prevents its slippage displacement on the jack of socket (22).
Be shaped on spring collar (23) in the socket openend of socket, the position that the other end contacts with socket cover (27) is equipped with rubber bullet circle (26).
Also as a whole of insulator in the socket.
The utility model modified model three-phase and quadrupole plug, socket series of products are on the basis that keeps the traditional product installation dimension, structure has been done bigger improvement, the work that makes it is reliable more, it is convenient to use, safely, have characteristics shockproof preferably, the rain and snow seepage.Can be for operational environments such as indoor, field reliably working under the harsh conditions comparatively.Be suitable between AC power frequency, the cable load of intermediate frequency mobile power station and do the usefulness that is electrically connected.Cable connects have been realized and can weld, target that again can crimping.
