Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art's all other embodiments obtained belong to what the present invention protected
Scope.
As shown in figures 1 to 6, a kind of EMC metal sheathed cables connector according to embodiments of the present invention, connects including metallic cable
Head body 1, metallic cable joint body 1 include first end of thread 2 and second end of thread 3, and first end of thread 2 is connected with nut,
Second end of thread 3 is connected with locknut 7, and first end of thread, 2 inside is equipped with annular groove, is equipped in annular groove into annular
The close spring 4 that side protrudes, the end face of first end of thread 2 are equipped with spacing ring 5, and first end of thread, 2 inside is equipped with bonding ring
6,6 outer wall of bonding ring is 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 prominent promptly block.
In order to facilitate understand the present invention above-mentioned technical proposal, below by way of in specifically used mode to the present invention it is above-mentioned
Technical solution is described in detail.
When specifically used, a kind of EMC metal sheathed cables connector according to the present invention, according to the outer diameter of shielded cable,
The corresponding bonding ring 6 of model of selection and metallic cable joint body 1, the insulating layer for peeling off shielded cable expose shielded layer,
Shielded cable is successively sequentially passed through into locknut 7 and sealing ring, shielded layer fold is returned to the outer surface of shielded cable, then
By bonding ring 6 through cable, while shielded layer is filled in into bonding ring 6, be until filling in the bottom of bonding ring 6
Only, corresponding crimping position is subjected to extruding fixation using hydraulic tongs, the bonding ring 6 with cable is then installed to gold
Belonging to inside cable connector body 1 so that the top of bonding ring 6 is in contact with the spacing ring 5 of metallic cable joint body 1,
The outer wall of bonding ring 6 is in contact with close spring 4, and the sealing ring propulsion above cable is installed to metallic cable connector sheet
1 the inside of body, then installs locknut 7, then tightens locknut 7, after metallic cable joint body 1 is passed through cabinet, so
It tightens and is fixed using hex nut afterwards.Wherein, one end of bonding ring 6 is equipped with inside necking 8, during installation, from setting
The one end for having interior necking 8 is promoted into metallic cable joint body 1, is easily installed.
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
Annular face contacts 360 ° existing.6 length of bonding ring is 42mm, after cable shield passes through bonding ring 6, uses hydraulic pressure
Pincers crimp, so as to fulfill larger contact area.The material of bonding ring 6 is preferably brass or red copper, surface treatment
Mode is nickel plating, has higher electric conductivity.Relatively low impedance ground is realized with upper type, so that electromagnetic interference can obtain
To preferably releasing.Because of 6 sets of bonding ring on the shielding layer, while using hydraulic tongs copper sheathing is clamped so that bonding ring 6
It is firmly connected with shielded layer, while cable has stronger elastic force in itself, so that shielded layer is clipped in cable outer layer and shielding
Between ground loop 6, so solve the problems, such as to contact between cable shield and bonding ring illusive.
Annular groove is equipped in first end of thread, 2 inside, the close spring prominent to annular inboard is equipped in annular groove
4, and spacing ring 5 is equipped in the end face of first end of thread 2, realize 6 contact with metallic cable joint body 1 of bonding ring
And connection, so ensure sufficiently large ring shaped contact area.By tightening the locknut 7 of metallic cable joint body 1, can make
Sealed ring deformation, while sealing ring pushes bonding ring 6 so that bonding, 6 with metallic cable joint body 1
Contact it is more firm and stablize.Then second end of thread 3 of metallic cable joint body 1 is installed on cabinet panel, led to
It crosses metallic cable joint body 1 to contact with cabinet panel, be contacted so as to fulfill cable shield with 360 ° of annular surfaces of cabinet, so
After reuse hex nut and be connected with second end of thread 3, tighten and fix.Not only realize the company of cable shield and cabinet
It connects, while realizes shielded layer and contacted with the face of cabinet, contact area is increased, above shielded cable of preferably releasing
EMC is disturbed.And the very high degree of protection that cable passes through cabinet is also achieved, IP degree of protection reaches IP68, also solves
The problem of cable stress release.In addition, cable has also obtained larger cable grasp and enhances the stability of cable
And fastness.
According to the cable of various outer diameter, the metallic cable joint body 1 of different size is produced, further according to the gold of different size
Belong to the bonding ring 6 that cable connector body 1 produces different size, can also by changing the thickness of bonding ring 6, for
The cable of various outer diameter uses same metallic cable joint body 1.
Wherein, metallic cable joint body 1, locknut 7, bonding ring 6, nut are by Nickel Plating Treatment, plating
It is required that anti-corrosion grade accomplishes C4 grades, 720 it is small when.
To sum up, by means of the above-mentioned technical proposal of the present invention, in a manner that shielded cable and bonding ring ring are connect,
Realize 360 ° of annular face contacts, so as to fulfill larger contact area, relatively low impedance ground, so that electromagnetic interference can obtain
To preferably releasing, while solve the problems, such as that illusive between cable shield and ground terminal and high-voltage power cable passes through
The problem of cable circulation during metal gland head, installation is quick, simply, at low cost, cost-effective.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modifications, equivalent replacements and improvements are made should all be included in the protection scope of the present invention.
