Description
Technical field
The utility model relates to a kind of connector screening structures, and in particular to a kind of for no-welding in push-pull connector
Shielding construction.
Background technique
It is widely used in the equipment in the fields such as medical machinery, telephone, intercom, Miniature Terminal, satellite telephony
Push-pull connector because it has many advantages, such as that small in size, easy to operate, electromagnetism interference, environmental resistance are good, but much makes
With, to electromagnetic shielding requirements height, the shielding construction of conventional push pull connector is usually all to pass through connector tail using conducting wire in environment
The tail nut in portion is connected with connector, then by the metallic shield stratum reticulare on conducting wire be directly welded on tail nut tail end realize with
The conducting of connector reaches shield effectiveness, not only complicated for operation, but also poor using the stability of welding manner shielding.
Utility model content
Technical problem to be solved in the utility model is the tail nut and connector that tail portion of connector is passed through using conducting wire
It is connected, then the metallic shield stratum reticulare on conducting wire is directly welded on tail nut tail end, it is not only complicated for operation, but also using weldering
The stability difference that the mode of connecing shields is, and it is an object of the present invention to provide a kind of no-welding shielding construction in push-pull connector, can incite somebody to action
Metallic shield stratum reticulare on conducting wire is pressed on the conical surface between shading ring and crimping set, is screwed in place by tail nut, compression
Crimping set realizes shielded layer processing in the case where no-welding, reaches shielding requirements.
The utility model is achieved through the following technical solutions:
A kind of no-welding shielding construction in push-pull connector, including it is threadedly attached in push-pull connector tail end
Tail nut, tail nut center is equipped with the through-hole passed through for conducting wire, is arranged with horizontally disposed crimping set, crimping in tail nut
It covers central coaxial and is equipped with cable-through hole, crimping puts on one end outer wall close to tail nut tail portion in cone structure, and crimping covers conical surface end
Outer diameter successively decreases along tail nut caudal directions, is arranged with shading ring between crimping set conical surface end and the inner wall of tail nut, shields
Covering ring inner wall also is the conical surface to match with crimping set conical surface end outer wall shape, and the conical surface end of crimping set is being shielded ring level
When extruding force on direction, crimping set conical surface end side wall can be shunk towards radial direction.
Metallic shield stratum reticulare on conducting wire can be pressed on shading ring and pressure by the connector screening structure of the utility model
On the conical surface between line set, is screwed in place by tail nut, compress crimping set, realized at shielded layer in the case where no-welding
Reason, reaches shielding requirements.The shielding construction of the utility model, wherein crimping set and shading ring respectively independence and are not connected with, first
It needs the wire termination connected to penetrate from the tail end of tail nut push-pull connector, is then then passed through the inner wall of shading ring, wherein
One layer of metallic shield stratum reticulare is enclosed with outside conducting wire, after conducting wire passes through the inner wall of shading ring together with metallic shield stratum reticulare together,
By the outer wall of metallic shield stratum reticulare removing conducting wire, then conducting wire is passed through to the cable-through hole of crimping set, so that metallic shield stratum reticulare stays

Between conducting, to reach the effect of shielding, in this way without the mode of welding by metallic shield stratum reticulare and tail portion of connector
It is connected, structure is simple, low in cost, practical function, the time needed for greatly saving welding, and compares welding side
The case where shield effectiveness is more stable for formula, and there is no the shielding of stress moment is failed at pad.
Crimping is covered circumferentially offers multiple open slots with cable-through hole perforation on the side wall at conical surface end, opens
Mouthful slot is parallel with crimping set axis and the end of open slot is through the conical surface end that crimping covers, and the conical surface end that crimping covers is being shielded
When extruding force in ring horizontal direction, open slot, which is squeezed, crimping to cover conical surface end side wall to receive towards radial direction
The side wall at crimping set conical surface end has been divided into muti-piece metal arc plate by contracting, i.e. open slot, and the inner wall of shading ring covers the conical surface to crimping
Active force in the radial direction is applied on the outer wall at end, so that the side wall stress at crimping set conical surface end, i.e. muti-piece metal arc plate
By radial compressing force, so that adjacent two blocks of metal arc plates press open slot while moving towards axis direction
Contracting, opening groove width be progressively smaller until be in close contact all metal arc plates on the inner wall of metal arc plate and the outer wall of conducting wire can not
Until inwardly shrinking again, clamping of the crimping set inner wall to conducting wire outer wall is just realized in this way；Itself special construction is covered by crimping
The setting of open slot can quickly be realized pair while ensure that conducting wire can be normally through the cable-through hole that crimping covers
The clamping of conducting wire outer wall.
Crimping covers screw thread on one end outer wall far from conical surface end and is socketed with fixing card block, and fixed fixture block is for being fastened on push-and-pull
In the inner wall of connector tail end, connects and also be provided with the central through hole passed through for conducting wire at fixture block center, it first will fixed fixture block
It is fastened in the inner wall of push-pull connector tail end, then crimping set is threadedly attached in fixed fixture block central through hole inner wall again
On, so that crimping set be fixed, it is avoided to rotate in the screwing operations of tail nut.
The end of shading ring is fixedly connected with tail nut, and the inner wall of shading ring is equipped with internal screw thread, and crimping covers outside conical surface end
Wall is equipped with the external screw thread that matches, and shading ring and tail nut is fixed as a whole, tail nut during screwing,
