Abstract
The utility model discloses a cable connector module, including a plug and a cable section connected with the plug. The space between the metal outer wall of the plug and the shielding layer of the cable section on the same end covers a metal foil. The space between the metal outer wall of the plug and the metal foil is sealed by circumferential weld. The space between the shielding layer of the cable section on the same end with the plug and the metal foil is sealed by circumferential weld. The metal foil is covered by a plastic cement shell, and the cable section close to the plug is sheathed with a magnetic loop. Adopting the cable connector module of the utility model can largely increase the radio frequency electromagnetic field radiation immunity of the cable, largely lower the radiation emission performance of the cable and largely promote the electromagnetic shielding performance of the cable and the equipment environment.
Description
Technical field
The utility model relates to connector, is specifically related to a kind of cable connector assembly.
Background technology
In numerous E1 signal transmssion lines, 8 core miniature diameter coaxial cables are used very extensive.The connector of 8 present core miniature diameter coaxial cables uses the SCI pin connector, be inserted in the SCI plug carrier, SCI plug carrier is inserted in the flat cable socket again, generally adopts 34 core flat cable sockets or 64 core flat cable sockets, and 34 core SCI plug carriers and 64 core SCI plug carriers.One 34 core flat cable socket can be used for 28 core miniature diameter coaxial cables, transmits 16 E1 signals (17,18 cores of flat cable are vacant), and one 64 core flat cable socket can be used for 48 core miniature diameter coaxial cables, transmits 32 E1 signals.Above this method be traditional method of attachment of generally adopting now, because flat cable socket and SCI plug carrier all are plastic shells, can't carry out electromagnetic shielding, therefore in reliability test, the cable that machine uses all is very big for the influence of many aspects, especially bigger for influences such as radio frequency electromagnetic field radiation immunity experiment, radiofrequency field conduction immunity experiment, conduction transmitting test, radiated emission tests, secondly to a certain degree influence is also arranged for esd immunity test, electrical fast transient (eft) immunity experiment etc.
Therefore, adopt this traditional method of attachment recited above, can't make product pass through present EMC (Electromagnetic Compatibility, electromagnetic compatibility) test at all.
The utility model content
The technical problems to be solved in the utility model provides a kind of cable connector assembly, and the cable connector that overcomes prior art can not carry out the defective of electromagnetic shielding in the junction of plug and cable.
For solveing the technical problem, the utility model adopts following technical scheme:
A kind of cable connector assembly comprises plug and the cable segments that is connected with described plug, the metal outer wall of described plug and and the screen of the described cable segments of its same end between the coated metal paper tinsel.
The further optimization of technique scheme is boxing sealing between the metal outer wall of described plug and the described metal forming, and boxing seals between the screen of the described cable segments of the same end of described plug and the described metal forming.
The further optimization of technique scheme is the outer injection moulding parcel of described metal forming plastic shell.
The further optimization of technique scheme is that described cable segments is being with magnet ring near described plug place.
Described plug can be made as the DB9 plug, and described cable segments is made as 8 core miniature diameter coaxial cables simultaneously.
Adopt cable connector assembly described in the utility model, greatly improved the radio frequency electromagnetic field radiation immunity of cable, greatly reduced the radiated emission performance of cable, greatly improved the capability of electromagnetic shielding of cable and facility environment.
Description of drawings
Fig. 1 is a cable connector assembly schematic diagram of the present utility model;
Fig. 2 is the schematic diagram behind the plastic shell of removing of a kind of cable connector assembly of the present utility model.
Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing the technical solution of the utility model.
8 core E1 full-shield cable connector assemblies as shown in Figure 1, having used at its A end has the DB9 of metal shell cable plug 111, the metal shell of DB9 plug 111 can be tightly fixing with the metal fixed leg of cable plug with the metal decking of many E1 plate, metal shell and metal decking closely are adjacent to, reliable overlap joint.Simultaneously between the metal shell of the screen of 8 miniature diameter coaxial cables of 8 core E1 full-shield connector cable assemblies and DB9 cable plug 111, wrap up fully with Copper Foil, and, as shown in Figure 2, all adopt 112 closed shields of soldering ring with the place of screen and DB9 cable plug 111 housing contacts.Also plastic shell is installed in injection moulding additional in the outside of Copper Foil and soldering ring 112, for further improving the Electro Magnetic Compatibility of cable connector assembly, also adding cover magnet ring 113 near A end place,, decide generally with other kind plug of BNC connector or CC4 connector or field engineering needs at B end shown in Figure 1 on opposite equip..Use this cable connector assembly, improved the capability of electromagnetic shielding of cable, veneer greatly.The radiated emission performance that has greatly improved the radio frequency electromagnetic field radiation immunity of 8 core miniature diameter coaxial cables and greatly reduced by 8 core miniature diameter coaxial cables is for having good effect by the EMC test.
Claims (8)
