Description

A kind of shell component of electric connector

Technical field

The utility model relates to technical field of electric connectors, especially a kind of shell component of electric connector.

Background technology

When the connector of prior art docks, adopt usually to be threaded or buckle ways of connecting enforcement fixed connection, the problem of existence is; The mode connection speed that is threaded is slow; The anti-vibration ability is used to be prone to take place to become flexible under vibration environment, causes product to connect and loses efficacy; The buckle ways of connecting is only managed the slow problem of connection speed that solved; But with the same mode of being rigidly connected that is that is threaded; Connector does not have the function of elastic compensating in the course of the work, has the anti-vibration ability equally, under vibration environment, uses to be prone to take place virtual connection; Cause the discontinuous phenomenon of electrical property to take place, influence the result of use of product.

The utility model content

The purpose of the utility model is the shell component of a kind of electric connector of providing to the deficiency of prior art.The utility model is provided with helicla flute and elastic washer between swivel nut and shell, make the connector state that is flexible connection, and effectively antivibration is locking, have simple in structure, connect the advantage reliable, that shielding properties is high, result of use is good.

The concrete technical scheme that realizes the utility model purpose is:

A kind of shell component of electric connector; Its characteristics comprise shell, swivel nut, elastic washer, plain washer and spring collar; Said shell is hollow multidiameter, and its external diameter is provided with step surface, and swivel nut is hollow multidiameter; Be provided with helicla flute, cascaded surface and annular groove on its internal diameter successively, the sidewall of swivel nut is provided with the gap that connects with annular groove; Said elastic washer is two; Be set with in the both sides of shell step surface; Swivel nut is inserted in by an end of shell; And cascaded surface and an elastic washer touch, and plain washer and spring collar are inserted in by the other end of shell, and spring collar places in the annular groove of swivel nut, plain washer is between another elastic washer and spring collar; The end of described swivel nut inner spiral groove is provided with groove.

The utility model is provided with helicla flute and elastic washer between swivel nut and shell, make the connector state that is flexible connection, and effectively antivibration is locking, have simple in structure, connect the advantage reliable, that shielding properties is high, result of use is good.

Embodiment

Consult Fig. 1, Fig. 2, Fig. 3; The utility model comprises shell 1, swivel nut 2, elastic washer 3, plain washer 4 and spring collar 5; Said shell 1 is hollow multidiameter, and its external diameter is provided with step surface 11, and swivel nut 2 is hollow multidiameter; Be provided with helicla flute 21, cascaded surface 22 and annular groove 23 on its internal diameter successively, the sidewall of swivel nut 2 is provided with the gap 24 that connects with annular groove 23; Said elastic washer 3 is two; Be set with in the both sides of shell 1 step surface 11; Swivel nut 2 is inserted in by an end of shell 1; And cascaded surface 22 and an elastic washer 3 touch, and plain washer 4 and spring collar 5 are inserted in by the other end of shell 1, and spring collar 5 places in the annular groove 23 of swivel nut 2, plain washer 4 is between another elastic washer 3 and spring collar 5;

Consult Fig. 1, Fig. 2, the end of described swivel nut 2 inner spiral grooves 21 is provided with groove 25.

The utility model is to use like this:

Consult Fig. 1, Fig. 2, Fig. 4, Fig. 5, the socket of connector is located in the shell 1, and the plug of connector is located in the connector 6; Connector 6 cylindricals are provided with pinning 61; When the plug of connector and socket are pegged graft, make helicla flute 21 engagements of pinning 61 and swivel nut 2 on the connector 6, rotation swivel nut 2; Drive connector 6 and on shell 1, move axially, the realization connector plug is connected with socket.

The course of work to the utility model further specifies as follows:

The locking of connector plug and socket:

Along with the rotation of swivel nut 2, helicla flute 21 drives pinning 61 and moves axially on shell 1 together with connector 6, at this moment; The end face of connector 6 touches and compels elastic washer 3, continues rotation swivel nut 2, when pinning 61 arrives the groove 25 of helicla flute 21 ends; The elastic force of compressed elastic washer 3 discharges; The end face that elastic force acts on connector 6 drives pinning 61 and gets in the terminal groove 25 of helicla flutes 21, and pinning 61 is by locked, the completion that is connected of connector plug and socket.

The elasticity connection status of connector plug and socket:

When connector plug and socket are under the normal connection status, at this moment, be located at connector plug in the connector 6 through groove 25 relative fixed of pinning 61 with swivel nut 2; Because the socket of connector is located in the shell 1; The both sides of shell 1 step surface 11 are respectively equipped with elastic washer 3, and wherein, the elastic washer 3 of a side is limited by the end face of connector 6; The elastic washer 3 of opposite side is limited by in the annular groove 23 of swivel nut 2 through plain washer 4 and spring collar 5; This shows that the axial motion of shell 1 restricts between two elastic washers 3, when receiving external impacts; The elastic force that shell 1 can overcome elastic washer 3 can produce between connector 6 and swivel nut 2 and move axially, and realizes that connector plug and the socket in the course of work is in the elasticity connection status.

Opening of connector plug and socket:

When needs are opened connector plug and the socket under the normal connection status; As long as apply an axial force to connector 6, connector 6 drives pinning 61 and in the groove 25 of helicla flute 21 ends, breaks away from, at this moment; Only need reverse rotation swivel nut 2, the plug of connector and socket can be opened;

The dismounting of shell and swivel nut:

Consult Fig. 1, Fig. 2, Fig. 3; Use instrument, through the gap on the sidewall of swivel nut 2 24, the spring collar 5 in the annular groove 23 is located in compression; Spring collar 5 is taken out in the annular groove 23 of swivel nut 2; Take out plain washer 4 and elastic washer 3 more successively, shell 1 and swivel nut 2 are realized separating, and realize the dismantlement work of shell and swivel nut.
