Abstract

The invention relates to a wire-connecting mechanism for soft and hard cables of a water pump, which comprises a soft wire cable and a hard wire cable, and is characterized in that the end of the soft wire cable is provided with a rubber socket, the rubber socket comprises a plug jack and a flexible conductor head, a conductive female connector is arranged in the plug jack, and the conductive female connector is contacted with the flexible conductor head; and the end of the hard wire cable is provided with a rubber plug, the plug comprises a jacket and a hard conductor head, the hard conductor head is contacted with a conductive male connector, the conductive male connector is plugged with the conductive female connector, and a fixing device is arranged outside the socket and the plug. In the proposal, the end of the soft wire cable is made into the socket, the end of the hard wire cable is made into the plug, and the conductive male connector of the plug is inserted in the conductive female connector of the socket during connecting and mounting so that the soft wire cable is communicated with the hard wire cable. Thus, the wire-connecting mechanism is convenient and labor-saving, has good insulation property without electric leakage, and is safe to use because the conductive male connector and the female connector are not exposed; besides, the fixing device is arranged outside the socket and the plug so that the wire-connecting mechanism has high connection strength and is firm to resist drawing.

Description

Soft, the hard cable connection of water pump mechanism

Technical field

The present invention relates to the interconnection technique of cable, can be used for various cables and connect, particularly relate to soft, the hard cable connection of water pump mechanism, be particularly useful for the water pump cable and connect.

Background technology

The water pump that does not have the machine port, distant the clarified water pump of irrigating usefulness, the immersible pump from power supply as flowing, so it is very long to connect the cable of power supply, usually there are 20～30 meters or longer, the long not only expense height of cable accounts for more than 30% of entire pump group investment, and very heavy, rollable comes after the take-up, so the suitable flexible cord (twisting into a strand by many little copper wires) that adopts.The cable that connects water pump is shorter, if but seep water easily, leak with the flexible cord cable, therefore, the cable that is connected on the pump motor can adopt rigid line (single thick copper lines).The flexible cord cable that connects power supply must be coupled together with the hard-line cable that is connected pump motor during use, just can switch on, prior art is soft, being connected to of hard cable fixed with the adhesive plaster wrapping after each the end of a thread directly connects, the shortcoming of its existence has: the one, and the immobilization with adhesive tape bonding strength is poor, the junction pulled easily when water pump moved, and connect pretty troublesome after pulling again; The 2nd, the adhesive plaster insulation property are poor, insulating properties only about 50%, and electric leakage is dangerous easily.

Summary of the invention

The objective of the invention is provides a kind of bonding strength good in order to overcome the shortcoming that prior art exists, firm, tension, good insulation preformance, soft, the hard cable connection of water pump safe in utilization mechanism.

The technical scheme of soft, the hard cable connection of water pump of the present invention mechanism is: comprise flexible cord cable and hard-line cable, the end that it is characterized in that the flexible cord cable is shaped on the rubber socket, the rubber socket comprises jack and flexible conductor head, and the conduction female joint is installed in the jack, and the conduction female joint contacts with the flexible conductor head; End in hard-line cable is shaped on rubber plug, and plug comprises sheath and hard wire head, and hard wire head contacts with the conduction male joint, and the conduction male joint plugs fixing device for installing outside socket and plug with the conduction female joint.

Soft, the hard cable connection of water pump of the present invention mechanism, socket is made in the end of flexible cord cable, plug (the position interchangeable of socket and plug in actual product is made in the end of hard-line cable, be that socket is in the rigid line end, plug can be in cord ends), during connection the conduction male joint of plug is inserted in the conduction female joint of socket, flexible cord cable and hard-line cable are connected, very convenient, laborsaving, good insulation preformance, leakproof, the conduction male joint is positioned at plug fully, the conduction female joint is positioned at socket fully, and promptly electric conductor does not expose, and is safe in utilization; Fixing device for installing outside socket and plug again, the bonding strength height, firm be not afraid of draw; With the back dismounting easily, need not be with annex materials such as adhesive plaster.

Soft, the hard cable connection of water pump of the present invention mechanism, the head inwall of its sheath is shaped on slot, and the head outer wall of socket is shaped on plug tenon, and plug tenon matches with slot.Because it is cable can adopt two-phase or three-phase,, therefore more time-consuming to slotting location the time so the quantity that male joint matches with female joint also is two groups or three groups, after slot and plug tenon have been arranged, be convenient to the location, in addition, also can increase the reliability of connection, prevent mutual rotation.The outer fixture of its described socket and plug is that double-screw bolt and nut are connected and fixed.Its described double-screw bolt and nut are that elastomeric material or plastics or metal material are made.The outer fixture of its described socket and plug is card post and card cap, is shaped on trip in the card post, blocks in the cap to be shaped on draw-in groove, and draw-in groove matches with trip.Its described card post is that rubber or plastics or metal material are made with the card cap.Its described rubber socket and flexible cord cable sheath are one, need not good airproof performance is installed.Its described rubber plug and hard-line cable crust are one, need not good airproof performance is installed.Between its described flexible conductor head and the conduction female joint weld layer first is arranged, between hard wire head and the conduction male joint weld layer second is arranged, make connection reliable, even also be not afraid of loosening at the deep water place.
