Specific implementation mode
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the shielded cable locking head with filter function of the present invention, as shown in Figures 1 to 4, including
The fixed seat of the fixed seat of the hollow metal for being installed for cable, metal includes the internal locking section 3 being located in casing 1 and position
In the outer locking section 4 outside casing 1, internal locking section 3 is integrally formed with outer locking section 4.
Cable includes being located at the first cable segment 12 for being not provided with shielded layer inside casing 1 and setting outside casing 1
It is equipped with the second cable segment 13 of shielded layer 14, the first cable segment 12 is located inside casing 1, is not set on the outer surface of this part cable
Shielded layer is set, casing 1 can carry out it metallic shield, is provided in the inner cavity of internal locking section 3 and be located on the first cable segment 12
On magnet ring 5, the end set of internal locking section 3 has a magnet ring fixing piece 8, in the axial both sides of magnet ring 5 in the inner cavity of internal locking section 3
It is respectively arranged with the first beam 6 and the second beam 7, the diameter of each beam is all higher than the diameter of magnet ring 5 so that radial stretch
The beam extension 15 for going out magnet ring 5 is wrapped in crimp on magnet ring 5.Magnet ring fixing piece 8 is by beam by magnet ring 5
It is fixed in the inner cavity of internal locking section 3, it is that the beam far from outer locking section 4 limits that magnet ring fixing piece 8, which has with the second beam 7,
Position cooperation is to fix the confined planes of magnet ring 5.When installation, magnet ring fixing piece 8 generates the pressure on axial direction during screwing
Clamp force makes beam deform upon, which realizes to the package of magnet ring 5, prevents from causing touching for magnet ring 5 and fixed seat when vibrations
It hits.
For application scenario difference, magnet ring can be adjusted according to harness and connection type and interference signal type,
According to interference type, differential mode, common mode filtering to single core cable, multi-core cable are realized.Meanwhile it can be according to the frequency of interference signal
The magnet ring of rate selection different frequency performance is filtered corresponding interference signal.
Be provided in the inner cavity of outer locking section 4 shielding clamp spring 9, shielding clamp spring 9 can deformation in an axial direction, shield 9 ring set of clamp spring
In on the second cable segment 13, the end set of outer locking section 4 has a clamp spring fixing piece 11, in shield card in the inner cavity of outer locking section 4
The outside of spring 9 is provided with collision mat 10, and clamp spring fixing piece 11 is fixed on outer locking section 4 by collision mat 10 by clamp spring 9 is shielded
In inner cavity.The force section 2 that nut structure is also wholely set between outer locking section 4 and internal locking section 3 is used for and the tools such as spanner
Cooperation, the end face of the close internal locking section 3 of force section 2 form the binding face being bonded with casing 1.
The installation process of the shielded cable locking head with filter function of the present invention is：When installation, pass through force first
Fixed seat is tightened on casing 1 by portion 2, secondly will handle the second cable segment 13 well and sequentially pass through shielding clamp spring 9, collision mat
10 and clamp spring fixing piece 11, it screws clamp spring fixing piece 11 and is fixed clamp spring 9 is shielded, the First Line inside casing 1 will be entered again
Cable section 12 sequentially passes through the first beam 6, magnet ring 5 and the second beam 7, and magnet ring fixing piece 8 is finally torqued-up to internal locking section 3
On, so that magnet ring 5 is fixedly secured, completes installation.Shielded layer on second cable segment 13 realizes that 360 degree of shieldings connect with casing, together
When the first cable segment 12 also complete magnet ring 5 perception filtering.
The shielded cable locking head with filter function of the present invention sets magnet ring on the basis of ensureing 360 degree of shieldings
Meter is fixed on inside shielding locking head, realizes the filtering to cable interference signal, reduces the energy that interference signal is transmitted on cable
Amount reduces the pressure to cable shielding duty requirements.The shielding locking head design structure is simple, and magnet ring is fixed reliably, can be directed to
Internal structure is complicated, and space is limited, the component of large volume inductance can not be used to be filtered in connectivity port.Meanwhile Ke Yigen
Magnet ring built in locking head is selected according to interference signal type and frequency range, effectively improves the Electro Magnetic Compatibility of system.
In other embodiments of the invention, the diameter of beam can also be identical as the diameter of magnet ring；Beam rope
It can be equipped with for accommodating magnet ring end to wrap up the recess portion of magnet ring end；It is not influencing in use, beam can also only be set
One；Shielding clamp spring can not also be set in the inner cavity of outer locking section；Collision mat can not also be set in the inner cavity of outer locking section.
