Description
Technical field:
The utility model relates to power supply and technical field of signal transmission cables, particularly relates to a kind of structure of pre-fabricated electric cables with ground.
Background technology:
To there is field connection consumption consuming time in traditional cable artificial in controls transfer, the high defect of wiring error rate, also increases wire loop joint and there is the problems such as virtual connection line, and on-site cable wiring waste especially severe; The processing unit (plant) of common pre-fabricated electric cables usually adopts with electrical connector housing for the process of screen and connects, and is then connected with screen cabinet metallic support, draws without Special grounding wire.Shortcoming limits electric connector material, must be metal material; If nonmetal connector then cannot implement effective bonding, the general cost efficiency of present enterprise is had a negative impact; In addition for sheathed shielded cable, screen and armour effective grounding be accomplished, there is no effective producing device at present, can only adopt and destructiveness making is carried out to cable, repeatedly occur cable core insulation damages in actual use, signal transmission is unstable, the problems such as ground connection is unreliable.
Utility model content:
In order to solve this problem, the utility model discloses a kind of structure of pre-fabricated electric cables with ground, it can prevent signal transmission unstable effectively, cable core insulation damages, the appearance of the problems such as ground connection is unreliable.A kind of structure of pre-fabricated electric cables with ground, it comprises: connector dust cover (1), plug (2), jockey (3), the double wall heat draw (4), cable body (5), mark heat-shrink tube (6), the transparent heat draw (7), cable core (8), earth connection (9), connector (10), screen (11), armour (12), rubber cover (13) and PE pin (14), it is characterized in that: cable core (8) outside of described cable body (5) is provided with screen (11) successively, armour (12) and rubber cover (13), and screen (11) is connected by the PE pin (14) of connector (10) with the PE pin (14) of socket end and draws, be connected with earth connection (9) at the armour (12) of cable body (5) head, and by the fixing rear oppositely extraction of the jockey (3) of connector (10) afterbody, described plug (2) one end is connected with connector dust cover (1), its other end is connected with cable body (5), and cable body (5) is provided with the double wall heat draw (4) above successively, mark heat-shrink tube (6) and the transparent heat draw (7).
The beneficial effects of the utility model are:
The utility model has stable signal transmission, and ground connection is reliable, the features such as screen, armour, cable core, connector are mutually isolated.
Advantage of the present utility model and feature is described in detail in conjunction with following.
Accompanying drawing illustrates:
Fig. 1 is institutional framework schematic diagram of the present utility model;
Fig. 2 is the utility model connector and cable body connection diagram.
Embodiment:
Below embodiment of the present utility model is described in detail.
With reference to Fig. 1, shown in Fig. 2, the utility model discloses a kind of structure of pre-fabricated electric cables with ground, it comprises: connector dust cover (1), plug (2), jockey (3), the double wall heat draw (4), cable body (5), mark heat-shrink tube (6), the transparent heat draw (7), cable core (8), earth connection (9), connector (10), screen (11), armour (12), rubber cover (13) and PE pin (14), it is characterized in that: cable core (8) outside of described cable body (5) is provided with screen (11) successively, armour (12) and rubber cover (13), and screen (11) is connected by the PE pin (14) of connector (10) with the PE pin (14) of socket end and draws, be connected with earth connection (9) at the armour (12) of cable body (5) head, and by the fixing rear oppositely extraction of the jockey (3) of connector (10) afterbody, described plug (2) one end is connected with connector dust cover (1), its other end is connected with cable body (5), and cable body (5) is provided with the double wall heat draw (4) above successively, mark heat-shrink tube (6) and the transparent heat draw (7).
Preferably: without field connection when the utility model uses, it does not have destructive making to cable in whole precasting process, cable core can not exist and cut bad inside hidden danger (this hidden danger is indiscoverable in pre-fabricated electric cables finished product detection) and have electricity worst case ground connection, operating personnel can not damage personnel when contacting with electric connector simultaneously, are conducive to promoting the use of.
The beneficial effect of the present embodiment is:
The utility model has stable signal transmission, and ground connection is reliable, the features such as screen, armour, cable core, connector are mutually isolated.
