Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, the every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the range of the utility model protection.
As shown in figures 1 to 6, according to a kind of EMC metal sheathed cables connector of the utility model embodiment, including metal electricity
Cable joint ontology 1, metallic cable joint body 1 include first end of thread 2 and second end of thread 3, and first end of thread 2 connects with nut
It connects, second end of thread 3 is connect with locknut 7, and first end of thread, 2 inside is equipped with annular groove, and directed loop is set in annular groove
The end face of close spring 4 outstanding on the inside of shape, first end of thread 2 is equipped with spacing ring 5, and first end of thread, 2 inside is equipped with shielding and connects
Ground ring 6,6 outer wall of bonding ring are in contact with close spring 4.
One end of bonding ring 6 is equipped with inside necking 8.
Sealing ring is equipped between bonding ring 6 and locknut 7.
Bonding ring 6 uses brass or red copper.
Sealing ring uses silicon rubber.
Nut uses hex nut.
The outer ring of hex nut is equipped at intervals with promptly block outstanding.
In order to facilitate the above-mentioned technical proposal of the utility model is understood, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
When specifically used, a kind of EMC metal sheathed cables connector according to the present utility model, according to the outer of shielded cable
Diameter selects the bonding ring 6 and metallic cable joint body 1 of corresponding model, and the insulating layer for peeling off shielded cable exposes shielding
Shielded cable is successively sequentially passed through locknut 7 and sealing ring, shielded layer fold is returned to the outer surface of shielded cable by layer,
Then bonding ring 6 is passed through into cable, while shielded layer is filled in into bonding ring 6, until filling in the bottom to bonding ring 6
Until portion, corresponding crimping position is subjected to extruding fixation using hydraulic tongs, then the bonding ring 6 with cable is installed
To inside metallic cable joint body 1 so that the top of bonding ring 6 connects with the spacing ring 5 of metallic cable joint body 1
It touches, the outer wall of bonding ring 6 is in contact with close spring 4, and the sealing ring propulsion above cable, which is installed to metallic cable, to be connect
1 the inside of head ontology, then installs locknut 7, then tightens locknut 7, and metallic cable joint body 1 is passed through cabinet
Afterwards, it then tightens and is fixed using hex nut.Wherein, one end of bonding ring 6 is equipped with inside necking 8, when installation,
It promotes, is easily installed into metallic cable joint body 1 from one end equipped with interior necking 8.
A kind of EMC metal sheathed cables connector, after the insulating layer for peeling off shielded cable, exposed length is the shielding of 40mm
Layer then passes through the bonding ring 6 that length is 42mm and is connect with cable shield ring, and bonding ring 6 is real with cable shield
Existing 360 ° of annular face contacts.6 length of bonding ring is 42mm, after cable shield passes through bonding ring 6, uses hydraulic pressure
Pincers crimp, to realize larger contact area.The material of bonding ring 6 is preferably brass or red copper, surface treatment
