Abstract
The utility model provides a rectangular connector for electric cable shielding layer ground connection on a subway vehicle. The rectangular connector comprises shielding electric cables, a metal ground connection plate and a connector plug seat. The rectangular connector is characterized in that the metal ground connection plate is fixed on the connector plug seat, the front ends of the shielding electric cables are stripped in such a way that electric cable shielding layers and electric cable inner layer electric wires are exposed in a segmented manner, the electric cable inner layer electric wires are inserted in an insulator assembly on the connector plug seat, and the electric cable shielding layers are fixed on the metal ground connection plate through metal bundling bands. The rectangular connector is characterized in that effective ground connection of shielding wires is realized, the problem that a shielding net is wound together and operation cannot be realized due to an oversize wire harness when more than 60 shielding wires are grounded is solved. The shielding layers and the inner electric wires of the shielding electric cables are integrated, shielding layers and the inner electric wires are free from mutually pulling force, shielding layer breakage can be prevented, and shielding effect of the electric cables is guaranteed.
Description
Technical field
The utility model relates to a kind of for the electric equipment on railcar, is specifically related to a kind of rectangular connector for cable shielding layer earthing.
Background technology
The rectangular connector that railcar tradition is used, in the processing of shielding conductor ground connection, the shielding conductor 12 of every cable 11 to be drawn and insulating barrier is twisted into one to be fixed on shield clip 13, as shown in Figure 1, the method is applicable to the less situation of shielded type cable and uses, in Fig. 7 example, only have 6 shielding conductors to need ground connection, and rectangular connector specifications and models are 72 cores, can connect 72 cables, the shielding conductor that exceedes 60 if having needs shielding layer grounding processing, cable is too much, the size of connector screening support and perforate number are limited, too much screen cannot adopt conventional method to realize bonding, between cable shield net and internal wire, there is a pulling force of pullling mutually simultaneously, in the time that the subway train chief time is moved the dismounting repeatedly of vibrations and wiring change, may cause screen to be pulled off, cannot play the effect of shielding.
Utility model content
In order to solve the above problem existing in background technology, the utility model provides a kind of rectangular connector, for the cable shielding layer earthing of railcar, the shielding conductor grounding method that this connector is can be a kind of simple in structure, be convenient to operating personnel's execute-in-place and later maintenance.
For achieving the above object, the utility model adopts following technical scheme:
On a kind of railcar for the rectangular connector of cable shielding layer earthing, comprise shielded type cable, metal ground plate and connector body, it is characterized in that, metal ground plate is fixed on connector body, shielded type cable front end is shelled into segmentation and is exposed cable shield and cable internal layer electric wire, cable internal layer electric wire inserts the insulator assembly on connector body, and cable shield is fixed on metal ground plate by metal binding belt.
Described metal ground plate comprises connecting plate and fixed feet, on connecting plate, be provided with colligation hole, metal binding belt is fixed on the cable shield of shielded type cable on connecting plate through colligation hole, and fixed feet end is provided with fixing hole, and metal ground plate is fixed on connector body by fixing hole.
Between the cable shield that described segmentation is exposed and cable internal layer electric wire, be provided with transparent heat Heat-Shrinkable Tubings.
The beneficial effects of the utility model are:
The present invention is simple and efficient, convenient operation, both realized the effective grounding of shielding conductor, also solved while exceeding 60 shielding conductor ground connection gauze screen around the excessive problem that cannot operate of wire harness together, the screen of shielded type cable and internal wire are an entirety, the power of not pullling mutually before both, can not cause the fracture of screen, has ensured the shielding action of cable.Compared with tradition, save workman's operating time, safe and reliable.
