Description
Technical field
The utility model belongs to electronics field, cable clamping device fixing after especially a kind of cable is connected with electric connector.
Background technology
Along with widely using of round electric connector, the attaching of cable needs reliably, fast to complete., the annex overwhelming majority of current round electric connector is screw-type structure, namely needs the connection being realized annex and electric connector by screw thread rotation, inefficiency; Secondly, electric connector institute distribution cable core number is a lot, and screw thread rotation can make cable be distorted, be wound around, easily occur that the fracture of cable conductor weld or weld have stress, when electric connector bears certain environmental test, there will be wire fracture, have a strong impact on the reliability of the transmission of electric connector.
Summary of the invention
The purpose of this utility model is, provides one fast, reliably can connect round electric connector annex, and can also improve the device of electric connector environmental resistance.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of Pushpulll locking of the utility model locking clamping type shield tail annex, comprise housing, ball, adapter sleeve, cable clip and clamp, described ball is three, in the housing evenly distributed by the interval of 120 degree at circumferencial direction, described adapter sleeve is installed on the housing, and described cable clip is provided with clamp.
Further, described housing is designed with bail, and bail is two.
Further, described housing is provided with red colour circle, described cable clip is provided with alignment mark.
Further, two shading rings are also comprised.
The utility model has a little following:
1, this annex adopts the mode that ball and adapter sleeve combine, the quick connection that can realize annex and electric connector be separated;
2, this annex is direct insertion structure, does not need to rotate, and effectively can prevent cable breakage;
3, this annex is provided with red locations mark, can the change of effective reminding user part position;
4, this annex can realize the electro-magnetic screen function of 360 degree.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Quick connection
Three balls 6 are evenly arranged in housing 4 in circumference by the interval of 120 degree by this annex, rely on the moving axially of adapter sleeve 8 (namely by the pushing of adapter sleeve 8, pull out two actions) to adjust the radial displacement of ball 6, thus the locking realizing annex and electric connector be separated.This locking mechanism, compared with screw connected structure, has and connects and be separated quick, easy, efficient feature.
Prevent cable distortion
Owing to attachment housings 4 being designed with double card nail 5, cable clip 15 is designed with convex key 22, when annex to be connected with electric connector or to be separated, the housing 4 of annex can not rotate relative to electric connector with cable clip 15, thus effectively prevent the distortion of cable 21 at solder joint place, winding, even rupture, and the distortion of cable shield 12, fracture.
Effective identification annex gets loose, it is not in place to install
This attachment housings 4 is provided with red colour circle 11, and when annex gets loose or be not installed to tram, red colour circle 11 can not be connected cover 8 and hide completely; Cable clip 15 is provided with red alignment mark 17, the convex key 22 not being connected to tram or cable clip 15 when swivel nut 14 does not coincide with keyway 23, red alignment mark 17 will follow closely 5 with annex main card, electric connector major key not on same straight line, play the effect of reminding user.
Realize shielding
This annex is shading ring 10 and shading ring 13 in housing 4 indoor design, and after cable 20 penetrates in cable clip 15, cable shield 12 is held between shading ring 10 and shading ring 13, realizes the electromagnetic shielding of cable 20 and whole connector 360 degree.
This annex possesses 4 functions, is the annex that in electric connector accessory, function is the most complete.
The connection of annex and electric connector 1 adopts double card to follow closely 5 contrapositions, three balls 6 lock after pushing ball grooves 3, then is realized by the mode that the adapter sleeve 8 of annex is spacing.Wherein double card is followed closely 5 structures and had both been achieved accurate contraposition when annex is connected with electric connector 1, and also prevent the rotation of whole accessory structure, it is more reliable, convenient to connect simultaneously.
Axis (direction of arrow) play is there is after preventing adapter sleeve 8 fixing, so, the housing 4 of adapter sleeve 8 tail end arranges a ring-shaped rubber sealing ring 9 and is tightly placed on housing 4, prevent the axial endplay of adapter sleeve 8.
After sealing ring 9 assembles, swivel nut 14 carries out screwing being connected with housing 4, and while screwing connection, the cable clamp be made up of swivel nut 14, cable clip 15, snap ring 16, clamp 18, screw 19 achieves connection.For prompting user in use annex to get loose produced impact, cable clip 15 is provided with red contraposition mark 17.
While swivel nut 14 screws, it drives cable clip 15 to extrude shading ring 13 and is tightly held between shading ring 10 and shading ring 13 by cable shield 12, ensure that the electromagnetism continuity of electric connector 1, annex 4 ~ 19,22,23 cable 20.
Connect and separating step (see Fig. 2):
1) cable 20 of group good cable 21, cable shield 12 is passed in the direction of arrows successively from cable clip 15, swivel nut 14, shading ring 13;
2) cable 21 is passed shading ring 10, housing 4 successively, then, be welded in the corresponding contact part weldering cup of electric connector 1;
3) mobile shell 4, bail 5, ball 6, sealing gasket 7, adapter sleeve 8, sealing ring 9, shading ring 10 in the direction of the arrow, after bail 5 and ball 6 enter keyway 2, ball grooves 3 respectively completely, promote adapter sleeve 8 in the direction of the arrow until it covers in the red colour circle 11 on housing 4 completely;
4) smooth for cable shield 12 is placed on shading ring 10, then puts shading ring 13 on cable shield 12;
5) screw swivel nut 14 in the direction of the arrow, screw in process, ensure the major key of alignment mark 17, bail 5, electric connector 1 on the same line;
6) last, cover clamp 18, and tighten screw 19 and make clamp 18 clamping cables 20, namely cable 20 is clamped fixing.
By above step, the connection of electric connector accessory can be completed.Reverse operating, can complete the separation of electric connector accessory.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
