Abstract

The utility model relates to the electric connector technical field, in particular to a connector striking flake assembly structure. The striking flake comprises a reverse hook which is used to assist the connector to insert and to prevent moving backwards, the reverse hook is arranged on an elastic arm which connects the fixing portion of the striking flake, a pin is arranged on the front end of the fixing portion of the striking flake, the pin is axially inserted in a jack on a rubber core end portion, the pin is provided with a back-preventing convex prick which is clamped in the jack, a supporting pin is arranged on the lower side of the fixing portion, and is perpendicularly inserted in a slot which is preset in the casing. The structure can well limit the front, back, left, right, and top and bottom directions of the fixing portion, thereby avoiding the phenomenon of dislocation when in pressing, and ensuring the normal projected insertion of the reverse hook, having convenient assembly and long service life, and increasing the usage property of the connector.

Description

Connector shell fragment package assembly

Technical field:

The utility model relates to technical field of electric connectors, refers in particular to a kind of connector shell fragment package assembly.

Background technology:

Known, be used for the connector of signal of telecommunication transmission, because easy to use, have that promptly to pull out be plugging function, thereby be widely used in electronic product.

Glue core grafting screens for subconnector generally is provided with on connector and can pushes shrapnel, but this shell fragment has the overhead kick of subconnector grafting and anti-back, and overhead kick is arranged on the elastic arm, and elastic arm connects the fixed part of shell fragment.And in the prior art, because installing and fixing of shell fragment is not very desirable, after repeatedly pushing, shell fragment very easily misplaces, and makes overhead kick lose due effect, and useful life is short.

Summary of the invention:

The purpose of this utility model is to provide a kind of mounting structure stable, and the connector shell fragment package assembly of ease of assembly.

For achieving the above object, the utility model adopts following technical scheme:

Connector shell fragment package assembly, a subconnector is pegged graft and the overhead kick of anti-back but this shell fragment has, overhead kick is arranged on the elastic arm, elastic arm connects the fixed part of shell fragment, end has a pin before the fixed part of shell fragment, this pin axially inserts the jack on the glue core end, and pin is provided with the protruding thorn of anti-back and is connected in the jack; The downside of fixed part is provided with feet, and feet vertically inserts in the default slot of enclosure.

Shell fragment is a bluff body, and elastic arm and fixed part be arranged in parallel up and down, and the rear end links together, and is the U-shaped that level is put.

At interval two feets before and after the downside of fixed part has, and the enclosure correspondence be provided with before and after two slots, wherein the back slot is one to have the semi-closed structure of rear retaining surfac, and preceding slot structure is on a transverse rod strip, for vertically dissecing gained; The trailing flank of transverse rod strip is the inclined plane under retreading one day.

The utility model is provided with pin at the fixed part front end of shell fragment, and the fixed part downside is provided with feet, and axially insert jack on the glue core end by pin, and pin is provided with the protruding thorn of anti-back and is connected in the jack, and feet vertically inserts in the default slot of enclosure; What this structure limited fixed part well reaches above-below direction all around, so that guarantees to push Shi Buhui and the phenomenon that dislocation takes place fixed part occurs, just guarantees that also screens is normally protruded in the overhead kick on the elastic arm; Easy to assembly, long service life, the serviceability of raising connector.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

See shown in the accompanying drawing 1～8 that connector shell fragment package assembly described in the utility model includes glue core 10, shell fragment 20 and shell 30, glue core 10 back edges are formed with card platform 11, and draw-in groove 31 interior the formation axially that are connected in shell 30 front end inboards by card platform 11 are connected; But shell fragment 20 has the overhead kick 21 of subconnector grafting and anti-back, and overhead kick 21 is arranged on the elastic arm 22, and elastic arm 22 connects the fixed part 23 of shell fragments.Elastic arm 22 by after stretch out forward, have one axial sudden strain of a muscle position groove 12 ammunition feed arm 22 to stretch out setting on the glue core 10 just, overhead kick 21 is positioned on the front end of glue core, overhead kick 21 elastic bumps and be used for subconnector peg graft location and anti-back; Also be provided with press section 24 on the elastic arm 22, conveniently push and control overhead kick 21, thereby realizing triping extracts connector.

Shown in Figure 2, shell fragment 20 is a bluff body, and elastic arm 22 and fixed part 23 be arranged in parallel up and down, and the rear end links together, and is the U-shaped that level is put.End has a pin 25 before the fixed part 23 of shell fragment, and the downside of fixed part 23 is provided with feet 26; Shown in Fig. 3,4,5,6, during installation, pin 25 axially inserts the jacks 13 on glue cores 10 ends, and pin 25 is provided with the protruding thorn 251 of anti-back and is connected in the jack 13, restriction fixed part 23 retreats, make shell fragment 20 relative motionless with glue core 10 in the axial direction, simultaneously, cooperate with jack 13 by pin 25, but the fixed part front end of relative fixed shell fragment 20 also, occur the fixed part front end when preventing to push shrapnel and lean forward, and the situation that the rear end upwarps has good stability.

In the slot 32 of feet 26 vertical insertion shell 30 internal preset of fixed part 23 downsides, thereby further limit about fixed part and upper-lower position.Shown in Fig. 7,8, in the present embodiment, two feets 26 at interval before and after fixed part 23 downsides have, and shell 30 inner correspondences are provided with front and back two slots 32, the thickness coupling of the width of slot 32 and feet 26 has good assembling effect.In two slots, back slot 32 is one to have the semi-closed structure of rear retaining surfac, rear retaining surfac restriction feet 26 retreats, and preceding slot 32 is configured on the transverse rod strip 33, for vertically dissecing gained, transverse rod strip 33 is the rear wall of draw-in groove 31 just, the trailing flank of transverse rod strip 33 is the inclined plane under retreading one day, relatively lengthening and feet 26 mating surface, the inclined plane has the trend that leans forward simultaneously, better the card platform 11 of twelve Earthly Branches top glue core 10 is structural good.

Shown in Fig. 4,8, in the present embodiment, with pin 25 preceding feet 26 in succession, some protrudes slot 32 forward when assembling, and what jack 13 downsides that insert glue core 10 extended dissects in the hole, increase being connected between shell fragment fixed part and the glue core, the structural strength of connection is good, is difficult for beat and misplaces.

The utility model optimized Structure Design is strengthened the fixed part 23 of shell fragment and the assembled relation between glue core 10 and the shell 30, and is stable better, and difficult the dislocation guarantees that screens is normally protruded in the overhead kick 21 on the elastic arm 22, improves the serviceability of connector.
