Abstract

The utility model relates to an anti-pull-off cable, an anti-pull-off socket and an anti-pull-off plug thereof. The socket is mainly composed of a conducting spring strip, the outer sleeve of the socket and the front cover of the socket. The back end of the front cover of the socket is provided with a fixing seat. The conducting spring strip is cast into integration with the fixing seat. The plug is mainly composed of the outer sleeve of the plug, a conducting strip and the front cover of the plug, and a conducting strip with a clamping head is fixed on the front cover of the plug. The utility model has the advantages that the conducting strip has large contacting area with the conducting spring strip; the conducting strip and the conducting spring strip can conduct large electric current; the conducting strip on the plug has a clamping head, so that the plug can lock the socket without disengagement; each of the rear ends of the plug and the socket has a power line locking device, which prevents the power line separating from the connecting terminal caused by suffering external force.

Description

Anti-pull-off socket and plug for electric wire and cable

The utility model belongs to a kind of jockey, particularly a kind of slip-off preventing electric wire, cable socket and plug thereof.

At present, China still belongs to blank, the mode that especially jumbo electric wire, cable all adopt wire rod directly to be connected usually aspect the removably connecting of electric wire, cable, its connection was both loaded down with trivial details, effort again, particularly for frequent dismounting establish line temporarily, very inconvenient in the construction; And the capacity of existing socket, plug is less, and the reliability that socket and plug connects is lower, comes off easily.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of slip-off preventing electric wire easy to connect, safe and reliable, capacious, cable socket and plug thereof are provided, to satisfy the on-the-spot needs of establishing line temporarily.

The utility model slip-off preventing electric wire, cable socket mainly are made up of conductive reed, socket overcoat and the socket front shroud that is installed in socket overcoat front end, rear end at the socket front shroud is equipped with holder, conductive reed and holder cast solid, conductive reed is made up of arc section conductive plate and square-section conductive plate, in the rear end of socket overcoat the power line tightening cover is installed also.

The utility model also have one with above-mentioned slip-off preventing electric wire, the matching used plug of cable socket, it mainly is made up of plug overcoat, conducting strip and the plug front shroud that is installed in plug overcoat front end, on the plug front shroud, also be fixed with the conducting strip of a band dop, in the rear end of plug front shroud the cover plate that band is isolated gusset is installed, the locknut of splitting of locking power line also is installed in the rear end of plug overcoat.

The utility model compared with prior art has following advantage:

1. conducting strip on the plug and the conductive reed contact area on the socket are big, connect reliably, therefore, can pass through bigger electric current.

2. the conducting strip on the plug has dop, and plug and socket are locked mutually, is difficult for throwing off.

3. the rear end of plug and socket all has the power line locking device, has prevented the phenomenon of power line because of come off from terminals by external force.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Figure 11 is the utility model user mode schematic diagram.

To shown in Figure 5, the utility model slip-off preventing electric wire, cable socket have a socket overcoat 3 as Fig. 1, and the socket front shroud 10 of band jack is installed by screw 11 at the front end of socket overcoat 3; Rear end at socket front shroud 10 is equipped with holder 6 by screw 9, has the isolation gusset 6a that conductive reed 8 is separated on the holder 6, is in contact with one another between the power line preventing, causes short circuit; Holder 6 and conductive reed 8 mutual cast solids, conductive reed 8 cuts conductive plate 8b by arc section conductive plate 8a and rectangle and forms, and one of them arc section conductive plate 8a is processed into semicircle, so that be connected with conducting strip on the plug, fixing between conductive plate 8a and the conductive plate 8b with rivet 7, jack on the front end alignment socket front shroud 10 of conductive reed 8 is equipped with the screw 4 and the pad 5 of fastening power line on the wiring point of conductive reed 8 rear ends; Rear end at socket overcoat 3 also is equipped with tightening cover 1, and tightening cover 1 usefulness screw 2 is fixed on the socket overcoat 3, so that power line is locked.

Extremely shown in Figure 10 as Fig. 6, with slip-off preventing electric wire, the matching used plug of cable socket a plug overcoat 19 is arranged, front end at plug overcoat 19 is equipped with plug front shroud 14 by screw 21, plug front shroud 14 and conducting strip 12 and conducting strip 13 mutual cast solids, the cross section of conducting strip 12 and conducting strip 13 is a circular arc, the screw 17 and the pad 18 of fixed power source line are installed on the wiring point of conducting strip 12 and conducting strip 13 rear ends, on conducting strip 12, also have a dop, so that plug and socket are locked mutually; Rear end at plug front shroud 14 is equipped with cover plate 16 by screw 15, is processed with on the cover plate 16 to isolate gusset 16a, is in contact with one another between the power line preventing, causes short circuit; What the locking power line also was installed in the rear end of plug overcoat 19 splits locknut 22, and it is fastening to split locknut 22 usefulness screws 20.

As shown in figure 11, during use, can be earlier power line be connected with the wiring point of the conducting

strip

12,13 of the conductive reed 8 of socket and plug respectively, and with tightening cover 1 with to split locknut 22 fixing respectively, then the conducting strip on the

plug

12,13 is inserted in the socket, and plug and socket rotated mutually, the dop on the conducting strip 12 can be locked socket and plug mutually; When needs are thrown off, only need plug and socket is rotated in the opposite direction, plug just can be pulled up from socket.
