The utility model content

The utility model has overcome deficiency of the prior art, and a kind of simple in structure, stable and reliable operation Plugs and Sockets for Industry is provided.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of Plugs and Sockets for Industry comprises clamping nut, cable line ball cover, plugs and sockets body, sealing ring, pressing plate, sleeve, latch, positioning head, set bolt, folding lid, socket guiding tongue, plug guiding tongue, the outer round recessed of body; Four hold-down nuts all distribute on the interior garden of described plugs and sockets body, four connecting bolts pass positioning head successively and are fastened on four nuts with installing the pressing plate of sleeve, latch, make plug, the latch accurate positioning of electric energy transmitting, install firmly that more stable work is reliable.

As preferably, the connecting thread inner face of described plugs and sockets body is arranged to taper, and the crimping face of cable line ball cover also is taper.

As preferably, described jack body is provided with the installation leg, is provided with installing hole installing on the leg, socket is fixed on the power-supply device with two bolts by installing hole, and it is little to take up room.

As preferably, described positioning head is provided with positioning key or location notch, the lead positioning key on tongue, socket guiding tongue and the plug, the location notch on the socket of plug aimed at, plug could insert socket, it is more reliable and more stable that plug, socket will be connected, and avoided different types of plug, the mutual misconnection of socket simultaneously.

A kind of Plugs and Sockets for Industry beneficial effect described in the utility model mainly shows: 1, the connection cable of plugs and sockets is penetrated by the clamping nut end; through cable line ball cover; directly enter the wiring chamber of plugs and sockets body; this structure has been saved the traditional protection sheath in wiring chamber, reduces the volume of plugs and sockets.2, behind plug insertion socket, folding on socket lid is shown in an open position, after plug was extracted, the folding of socket was covered under the spring action at its hinge place closed voluntarily, has prevented entering of dust, foreign matter.3, positioning head is provided with positioning key or location notch, and it is more reliable and more stable that plugs and sockets is connected, and avoided the mutual misconnection of different types of plugs and sockets simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a socket parts decomposing schematic representation of the present utility model;

Fig. 3 is a plug parts decomposing schematic representation of the present utility model.

At Fig. 1, Fig. 2, among Fig. 3: 1 is the plugs and sockets clamping nut, 2 is plugs and sockets cable line ball cover, and 21 are line ball cover horn mouth, and 3 is the plugs and sockets body, 30 are socket guiding tongue, 31 are plug guiding tongue, and 32 is socket mounting hole, and 33 is plug, the socket horn opening, 34 for installing leg, 35 is the outer round recessed of body, and 36 is four nuts, and 4 is the plug sealing ring, 5 is the plugs and sockets pressing plate, 60 is socket and bush, and 61 is the plug latch, and 7 is plug, the socket positioning head, 70 is the location notch of socket positioning head, 71 is the positioning key of plug positioning head, and 8 is set bolt, and 9 are the folding lid.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

Four hold-down nuts 36 all distribute on the interior garden of plugs and sockets body 3, during assembling, the sleeve 60 of the latch 61 of plug and socket is contained in respectively on separately the pressing plate 5, to fix latch, the pressing plate 5 of sleeve is located on the interior garden of body of plugs and sockets, then positioning head 7 is inserted in latch separately, on the sleeve, pass positioning head 7 and pressing plate 5 successively with four construction bolts 8 again, by four nuts 36 on the plugs and sockets body with positioning head 7 with latch is housed, the pressing plate 5 of sleeve is fixed on the body of plugs and sockets, this structure makes the plug 61 and latch 60 accurate positionings of electric energy transmitting, install firmly, more stable work is reliable.

Be provided with two on jack body leg 34 is installed, installing hole 32 is arranged on the leg, socket is fixed on the power-supply device with bolt by installing hole, four bolt sockets of usefulness that this structure is more traditional take up room little.

With outer round recessed 35 places of body of sealing ring 4 embedding plugs, when plug insertion socket, the composition surface of socket compresses sealing ring 4, has played good sealing function.

Inserted terminal at plug is provided with guiding tongue 31, inserted terminal at socket is provided with guiding tongue 30, on the positioning head 7 of plugs and sockets, be provided with simultaneously trapezoidal positioning key 71, with trapezoidal location notch 70, have only the guiding tongue 30 of the guiding tongue 31 of plug, socket and the positioning key 71 on the plug, location notch 70 on the socket are aimed at mutually, plug could insert socket, will make the connection of plugs and sockets more reliable and more stable like this, has avoided different types of plug, the mutual misplug of socket simultaneously.

The connection cable of plugs and sockets is entered by clamping nut 1 end, passes cable line ball cover 2, directly enters the wiring chamber of plugs and sockets body, and this structure has been saved traditional wiring chamber protection sheath, has reduced the volume of plugs and sockets.After plugs and sockets carefully connects the wire, screw on the connecting thread of plugs and sockets body 3 by clamping nut 1, because Inner Front End 33 flues of plugs and sockets body connecting thread are dehisced, cable line ball cover 2 is made by rubber, and with also flue of plugs and sockets body screw thread contact position 21, so cable line ball cover 2 travels forward under the effect of clamping nut 1, its bore progressively dwindles vertically and connection cable is clamped sealing.

Behind plug insertion socket, folding on socket lid 9 is in opens the position, after plug was extracted, the folding of socket was covered under the effect of its hinge place spring closed voluntarily, has prevented entering of dust, foreign matter.

The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.To help to understand the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
