Description

A kind of electrical equipment screen bottom of cabinet portion cable plugging device

Technical field

The utility model relates to distribution technique field more particularly to a kind of electrical equipment screen bottom of cabinet portion cable plugging device.

Background technique

Electrical equipment screen cabinet is when accessing cable, especially in the place containing explosion hazard gas and steam, general meeting It is connected and sealed using connector is blocked, existing cable blocks the structure that connector generally uses spiral lock-on connection, this electricity Cable closure connector, which is deposited, to be easy to cause junction to loosen because cable is influenced by external force in the long-term use, to influence to seal Property, it should give improvement to this.

Utility model content

The purpose of this utility model is to provide a kind of electrical equipment screen bottom of cabinet portion cable plugging devices, to solve above-mentioned skill Art problem.

The utility model uses following technical scheme to achieve the above object:

A kind of electrical equipment screen bottom of cabinet portion cable plugging device, including clamping plate, annular groove, sealing ring, connector, feature Be: the upper surface of the clamping plate offers annular groove, and in a ring groove, the clamping plate is nested in connection for the sealing ring installation It on the lower union joint of head, and is connected and fixed by the rotary table of screw and connector, the connector further includes upper binding head, card Line plate, gum sleeve, pressure plate, housing screw are provided with card line plate on the upper binding head, and the gum sleeve is embedded in down On connector, end face and the lower end surface of rotary table are connected thereon, and lower end surface is provided with pressure plate, and the housing screw sequentially passes through Pressure plate and gum sleeve are threadedly engaged with rotary table.

On that basis of the above technical scheme, the thickness of the sealing ring is greater than the depth of annular groove.

On that basis of the above technical scheme, the card line plate is bolted with upper binding head.

On that basis of the above technical scheme, the pressure plate is that two semicircular rings being oppositely arranged are constituted, and outer circle is straight Diameter is less than the intracavity diameter of lower union joint.

On that basis of the above technical scheme, the housing screw has 6, is uniformly distributed on pressure plate.

Compared with prior art, the utility model has the advantage that the structure design of the utility model is reasonable, cost It is low；Card line plate is provided on connector, cable fixation is more firm；Sealing effect is more preferable, and long-time service is non-maintaining, safer Reliably.

Detailed description of the invention

Fig. 2 is the connector structural schematic diagram of the utility model.

Fig. 3 is the connector schematic diagram of internal structure of the utility model.

In figure: 1, clamping plate, 2, annular groove, 3, sealing ring, 4, connector, 5, upper binding head, 6, rotary table, 7, lower union joint, 8, card line plate, 9, gum sleeve, 10, pressure plate, 11, housing screw.

Specific embodiment

The utility model is further elaborated in the following with reference to the drawings and specific embodiments.

As shown in Fig. 1 ~ 3, a kind of electrical equipment screen bottom of cabinet portion cable plugging device, including clamping plate 1, annular groove 2, sealing ring 3, connector 4, it is characterised in that: the upper surface of the clamping plate 1 offers annular groove 2, and the sealing ring 3 is mounted on annular groove 2 Interior, the clamping plate 1 is nested on the lower union joint 7 of connector 4, and is connected and fixed by the rotary table 6 of screw and connector 4, The connector 4 further includes upper binding head 5, card line plate 8, gum sleeve 9, pressure plate 10, housing screw 11, the upper binding head Card line plate 8 is provided on 5, the gum sleeve 9 is embedded on lower union joint 7, and end face is connect with the lower end surface of rotary table 6 thereon, Its lower end surface is provided with pressure plate 10, and the housing screw 11 sequentially passes through pressure plate 10 and gum sleeve 9 and matches with 6 screw thread of rotary table It closes, the thickness of the sealing ring 3 is greater than the depth of annular groove 2, and the card line plate 8 is bolted with upper binding head 5, the compression Plate 10 is that two semicircular rings being oppositely arranged are constituted, and outside diameter is less than the intracavity diameter of lower union joint 7, the compression spiral shell Nail 11 has 6, is uniformly distributed on pressure plate 10.

Working principle of the utility model is: the utility model, when specifically used, the lower union joint 7 of connector 4 passes through electricity The cable in gas equipment screen bottom of cabinet portion pre-installs hole, then loads onto clamping plate 1 and sealing ring 3 and is connected by screw to fixation；By rubber sleeve Pipe 9 is nested in the incoming end of cable, and reserves wire length, and cable is penetrated connector 4 from 7 one end of lower union joint, makes rubber Gum cover pipe 9 withstands the lower end surface of rotary table 6, tightens the fixed cable of card line plate 8, pressure plate 10 is then mounted on gum sleeve 9 Bottom is loaded on housing screw 11, and tightening housing screw 11 makes pressure plate 10 move up extruding gum sleeve 9,9 inner ring of gum sleeve Diameter reduces, and is adjacent to cable lateral wall, forms sealing.

The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired Change, replacement and variant is still fallen within the protection scope of the utility model.
