Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of quick connection snatch-disconnect connector of present embodiment.As shown in Figure 1, plug 1 mainly comprises insulating base 12 behind insulating base 7 before the plug body 2, sheath 3, bail 4, jack 5, waveform Clip Reed 6, plug, pad 8, collar 9, cutting ferrule 10, plug rubber blanket 11, the plug, plug swivel nut 13 and hood 14.As shown in Figure 3, socket 15 mainly comprises insulating base 23 behind insulating base 18 before the spiral channel 16, contact pin 17, socket, sealing ring 19, jack housing 20, socket rubber blanket 21, socket swivel nut 22 and the socket.
Such as Fig. 1, shown in Figure 3, be provided with the positioning key of anti-error connection at the plug body outer surface of plug, be provided with the keyway that matches with positioning key at the jack housing inner surface of socket.Be provided with spiral channel with straightway at the jack housing lateral surface of socket, spiral channel comprises oral area section, middle part and end segment, spiral channel oral area section and socket axially parallel, the spiral channel bottom stage is axially vertical with socket, and the spiral channel middle part is inclined to miter angle and is connected between spiral channel oral area section and the spiral channel bottom stage.
Such as Fig. 1, shown in Figure 3, the plug body outside is arranged with cutting ferrule by the waveform Clip Reed, and cutting ferrule is provided with two holes of uniform circle distribution, and riveted joint has bail in two holes, and bail matches with spiral channel on the respective socket shell.Cutting ferrule cooperates with step on the plug body by the waveform Clip Reed, and fix the waveform Clip Reed by the plug swivel nut, arc groove coupling contact on the crest of waveform Clip Reed and the plug body step is connected, and the claw stop on the waveform Clip Reed is complementary with locking groove on the cutting ferrule and is fixedly connected with.
Such as Fig. 1, shown in Figure 3, plug is provided with hood.Be provided with the plug rubber blanket between the insulating base behind insulating base and the plug before the plug in the plug; Be provided with the socket rubber blanket between the insulating base behind insulating base and the socket before the socket in the socket.Be provided with sealing ring between the insulating base before jack housing and the socket.Be provided with sheath in the jack in the plug.Cutting ferrule is provided with collar, is provided with pad in the collar.
Such as Fig. 1, shown in Figure 3, be designed with the positioning key of anti-error connector on the plug body 2 of plug 1, the keyway on this positioning key and the corresponding butt-joint socket shell 20 cooperatively interacts.Prevent on the one hand that when connecting mistake corresponding to the non-sequence number that jack 5 is connected with contact pin connects, and guarantees on the other hand can not relatively rotate between plug body 2 and the jack housing 20.
Such as Fig. 1, shown in Figure 3, the cutting ferrule 10 on the plug 1 has two holes of uniform circle distribution, and riveted joint has a circular bail 4 in two holes, and bail 4 matches with spiral channel 16 on the respective socket shell 20.Spiral channel 16 bottom stage of jack housing 20 are axially vertical with socket 15, spiral channel 16 oral area sections and socket 15 axially parallels of jack housing 20, spiral channel 16 middle parts of jack housing 20 are inclined to miter angle and are connected between spiral channel 16 oral area sections and spiral channel 16 bottom stage.Spiral channel 16 oral area sections, spiral channel 16 middle parts and spiral channel 16 bottom stage all are rectilinear draw-in grooves.When plug 1 needs to dock with socket 15, only cutting ferrule 10 need to be rotated clockwise 90 degree, bail 4 rotates to the bottom stage of spiral channel 16, and plug 1 was stubbornly refused and can be extracted for axial lock with socket 15 this moment, had realized that plug 1 is connected with the quick of socket 15.When plug 1 needs release to separate with socket 15, only need to be with cutting ferrule 10 along being rotated counterclockwise 90 degree, bail 4 rotates to the oral area section of spiral channel 16, just plug 1 can be extracted from socket 15, has realized separating fast of plug 1 and socket 15.
As shown in Figure 1 and Figure 2, cutting ferrule 10 cooperates with plug body 2 steps by waveform Clip Reed 6, and fixes waveform Clip Reed 6 by plug swivel nut 13, and waveform Clip Reed 6 can be rotated in 360 degree scopes.When plug 1 with after socket 15 docks, the plug dextrorotation turn 90 degrees, cutting ferrule 10 along socket 15 axial displacements certain length, and compression waveform Clip Reed 6, cutting ferrule 10 is in the elastic force that axially is subject to waveform Clip Reed 6, bail 4 is fixed on the spiral channel 16 firmly, and the product of assurance present embodiment in use bail 4 can not separate with spiral channel 16, and namely cutting ferrule 10 can not occur loosening counterclockwise.
As shown in Figure 1, arc groove coupling on the crest of waveform Clip Reed 6 and plug body 2 steps, make cutting ferrule 10 at circumferencial direction certain rotational resistance be arranged with respect to plug body 2, guarantee that cutting ferrule 10 can in use not circle round and release unexpectedly, guarantee the security reliability of using.Locking groove on claw stop on the waveform Clip Reed 6 and the cutting ferrule 10 is complementary, and guarantees can not relatively rotate between cutting ferrule 10 and the waveform Clip Reed 6.
Present embodiment is compared with prior art, and the spiral channel of prior art is provided in a side of on the endoporus of cutting ferrule, is not easy to processing, and cost is high, and particularly when diameter was smaller, the processing spiral channel was very difficult even irrealizable in the hole.The spiral channel of present embodiment is provided in a side of the outer surface of jack housing, is convenient to processing, also can not be subject to the restriction of cutting ferrule size.The spiral channel of prior art is without straightway, so plug and socket plug together when being connected, and in the process of engagement, because there is engaging force, need to overcome engaging force by the component that is rotated in axial generation of cutting ferrule, guarantees to plug together smoothly to carry out.Particularly pin count is many or jack is large, and the power that need to screw is very large, is difficult to be rotated connect plug together.Spiral channel in the present embodiment has one section axial straightway, i.e. revotating card notch section.Directly just can realize engagement process with axial thrust, need to be by the revolving force of cutting ferrule, therefore plug together and be easy to.The waveform Clip Reed structure of prior art can only be leaned on frictional force between cutting ferrule and the waveform Clip Reed to prevent loosening in the cutting ferrule use procedure and the phenomenon of release occurs, and reliability is not high, is not suitable for especially the many occasions of access times.Fix between waveform Clip Reed in the present embodiment and the cutting ferrule, the crest of waveform Clip Reed and the groove fit between the plug body, in engagement, groove plays and prevents that the waveform Clip Reed from rotating, in use cutting ferrule is loosening and the phenomenon of release occurs to prevent product, so reliability is higher.
The above has described execution mode of the present utility model by reference to the accompanying drawings, but not limited by above-described embodiment when realizing, those of ordinary skills can make a variety of changes or revise within the scope of the appended claims.
