About two contact elements 22,32 of the first and second umbilical connector 12,14, Fig. 9 to 11 may further reference,
Its contact element 22,32 for only showing umbilical connector 12,14.
The contact element 32 of socket 18 further includes two electrical contact surfaces 34,36, the two electrical contact surfaces 34,36 are in electricity
It interacts under the inserting state of pluggable connecting device 10 with the electrical contact surface 28 of plug 16 and is electrically connected with providing.This will be
It is detailed below.
The contact element 32 of socket 18 further includes sacrifice contact 38, and cross section is substantially formed in a U-shape shape.It is connect via formation
The spring arm 40 of the part of element 32 is touched, sacrifice contact 38 is electrically connected with electrical contact surface 34,36, so that sacrifice contacts
Part 38 and two electrical contact surfaces 34,36 are in identical current potential.
Further, since spring arm 40, sacrifice contact 38 is separated with two electrical contact surfaces 34,36.
Sacrifice contact 38 is arranged in front of the contact element 32 of the socket 18 of direction of insertion observation.
It is same flat that spring arm 40 is also shaped so that sacrifice contact 38 and electrical contact surface 34,36 are located substantially on
Face.Spring arm 40 is arranged essentially parallel to the middle part that direction of insertion extends and generates height tolerance including being perpendicularly to the insertion direction
(referring specifically to Fig. 2).
In an illustrated embodiment, middle part is configured to the transition part for the upward gradient for having constant, so that spring arm
40 height slowly changes.Alternatively, middle part may be step-like.
Correspondingly, be arranged in the sacrifice contact 38 of 40 end of spring arm with spring arm 40 along electrical contact surface 34,
36 extend, and the spring arm 40 in region especially extended under electrical contact surface 34,36 has different height.
The shape of spring arm 40 and particularly middle part ensures one side spring arm 40 apart from 34,36 foot of electrical contact surface
Enough remote, another aspect sacrifice contact 38 has enough gaps can flexibly transport relative to electrical contact surface 34,36
It is dynamic.
Particularly by Fig. 9 to 11 as it can be seen that two contact surfaces 34,36 are arranged in the region of narrow portion 42, two of them are connect
Touching surface 34,36 is formed in the opposite sides of the narrow portion 42 (referring to special Figure 10).
The electrical contact surface 28,34,36 of umbilical connector 12,14 is preferably formed by noble metal, such as silver or gold, is made
Obtaining them has low resistance.
According to the one side of pluggable connecting device 10, exactly two is provided in each umbilical connector 12,14 and is connect
Contact element.To carry out data transmission via two conductors (" twisted pair ").
Referring to figs. 1 to 5, will now be explained how to establish hot-line insertion and extraction formula attachment device 10, that is, hot-line insertion and extraction formula connector 12,
How 14 be plugged in one another to provide electrical connection.
In insertion operation position shown in Fig. 1, because of shell 20,29 Mechanical Contacts, two hot-line insertion and extraction formula connectors 12,
14 have been pushed into one another.However, contact element 22,32 is not in contact with each other also.
In the position, switching arc S may have been formd between the sacrifice contact 26,38 faced, as shown
Shown in meaning property.Correspondingly, electrical connection may be had existed between the contact element 22,32 of umbilical connector 12,14.It opens
Powered-down arc S is formed between sacrifice contact 26,38, because they are respectively arranged in each plug-in company along direction of insertion observation
It connects before device 12,14.
Switching arc S can, for example, passing through especially grafting under a load, that is, at two during so-called " hot grafting "
Big potential difference between contact element 22,32 generates.
During insertion operation, two umbilical connectors 12,14 are pushed further into one another, and are thus reached and schemed
Position shown in 2, two of them contact element 22,32, and the sacrifice contact 26,38 being especially arranged on, directly
Connect Mechanical Contact.
Sacrifice contact 38 is arranged so that it can flexibly move and can thus move relative to contact surface 34,36
It is dynamic, as that can see from the comparison of Fig. 1 and Fig. 2.It is pressed against the sacrifice of socket 18 in the top 24 of the contact element 22 of insertion
The ramped shaped leading edge of contact 38 is to be pressed downward sacrifice contact 38.This is because sacrificial on the spring arm 40 that can flexibly move
The arrangement of domestic animal property contact 38 and be possibly realized.
From free end, up-front thickness is reduced along direction of insertion.Correspondingly, up-front ramp-like shape is designed so that
It is increased along direction of insertion observation slope.
Another switching arc can be generated in the position, this can especially be drawn by the capacitive character phenomenon occurred during " hot grafting "
It rises.
Two umbilical connectors 12,14 are further moved relative to each other, so that the top 24 of contact element 22 slips over
The sacrifice contact 38 of contact element 32.
In an illustrated embodiment, sacrifice contact 38 is constructed to so that it can be contacted relative to setting in sacrifice
Adjacent spring arm 40 between part 38 and electrical contact surface 34,36 tilts.Therefore the leading edge portion of sacrifice contact 38
It is folded down, so that when the contact element 22 of plug 16 is slided along the sacrifice contact 38 of socket 18 during being inserted into plug 16
When sacrifice contact 38 leading edge do not touch the electrical contact surface 28 of plug 16.
Specifically configured become of sacrifice contact 38 enables it to reversibly tilt relative to spring arm 40, so that sacrificing
Property contact 38 will automatically return to its initial position.
Now, plug 16 can be pushed further into socket 18, more specifically in socket contact 30, so that plug 16
Sacrifice contact 26 is pushed through the sacrifice contact 38 of socket 18 by the electrical contact surface 34,36 towards socket 18.
In position shown in Fig. 4, the sacrifice contact 26 of plug 16 is located at the electrical contact surface 34,36 of socket 18
In region.
However, the top 24 for being provided with the contact element 22 of sacrifice contact 26 does not contact electrical contact surface 34,36, make
The sacrifice contact 26 that obtaining them will not be corroded is made dirty.Among other things, this is because the geometry of contact element 22,
It is constructed to the contact plug with tapered tip 24.Correspondingly, recline socket 18 electrical contact surface 34,36 only portion
It point is the peripheral surface of contact element 22, however, this is not the part of the sacrifice contact 26 of corrosion.
In addition, the contact surface 34,36 of socket 18 is arranged in after ramped shaped side surface 44,46, and therefore contact surface
34,36 are located in the region of narrow portion 42.During insertion plug 16, ramped shaped side surface is pressed against on the top 24 of contact element 22
44,46, so that narrow portion 42 can widen.
Correspondingly, position shown in Fig. 4 does not indicate the inserting state of hot-line insertion and extraction formula attachment device 10.Until plug 16 by
Push-in socket 18 far enough to make two electrical contact surfaces 34,36 of socket 18 recline plug 16 electrical contact surface 28 with formed
Before electrical connection, not up to inserting state.The inserting state is in fig. 5 it is shown which illustrates the cross sections for being different from Fig. 1 to 4
Plane.
As seen from the figure, in the plugged state, the sacrifice contact 26 of plug 16 do not recline electrical contact surface 34,36 or insert
Any other part of the contact element 32 of seat 18.Correspondingly, in the plugged state the top of contact element 22 24 with contact
Gap is formed between element 32.
The sacrifice contact 38 of socket 18 does not contact the contact element 22 of plug 16 yet, because plug 16 is with corresponding
Recess portion 48, the sacrifice contact 38 of U-shaped cross-section are located in recess portion 48 with leaving 22 a distance of contact element.Therefore it is inserting
The sacrifice contact 38 for connecing socket 18 under state is contactless.
10008 additionally or alternatively, the leading edge of sacrifice contact 38 is provided with ramp-like surface, which makes
Banking motion can be carried out by obtaining sacrifice contact 38.This is for example when sacrifice contact 38 is reclined in the plugged state with phase
Occur when the element on surface inclined for direction of insertion, as shown in the examples like that (referring to Fig. 5).
The contactless positioning of sacrifice contact 38 in the plugged state also passes through sacrifice contact 38 can be relative to bullet
Spring arm 40 tilts and/or can ensure via the fact that spring arm 40 flexibly moves.
The contactless positioning of sacrifice contact 26,38 will typically ensure that the sacrifice contact corroded over time
Part 26,38 will not affect that the electrical connection quality under the inserting state of hot-line insertion and extraction formula attachment device 10, because they are not formed
A part of electrical connection.
The contactless positioning of sacrifice contact 26,38 in the plugged state can only pass through the geometry of contact element 22,32
Shape is realized.It can 10008 additionally or alternatively be ensured by the elasticity installation of sacrifice contact 26,38.
Sacrifice contact 38 is thus via two articulated linkages (link) and associated electrical contact surface 34,36 couplings
It closes.The articulated linkage is set as 40 form of spring arm, and sacrifice contact 38 and sacrifice are provided on spring arm 40
Additional tilt function of the contact 38 relative to spring arm 40.
The tilt function of usual sacrifice contact 38 can be implemented by the corresponding material portion of spring arm 40.The material
Material portion be then constructed to so that its reversibly, that is, be resiliently bent.
Plug 16 can also have main part, and corresponding contact surface 28 extends along direction of insertion from main part.
Main part can similarly include ramp-like shape, cooperate socket 18, especially socket 18 in the plugged state
Sacrifice contact 38.The ramped shaped region of main part extends along the direction opposite with direction of insertion, so that the slope is along insertion
Direction reduces and becomes contact surface 28.
During insertion, sacrifice contact 38 is slided along contact surface 28 as already explained first, is then arrived
Up to shortly before inserting state, due to main part ramp-like shape and shift, be more specifically pressed downward, this is because sacrificial
Domestic animal property contact 38 deviates (referring specifically to Figure 10 and 11) along ramped shaped region.
More specifically, the ramped shaped region of the main part of plug 16 and the ramped shaped protrusion of sacrifice contact 38 are met,
To because ramped shaped region and ramped shaped protrusion are correspondingly configured to and correspondingly enhance reversible displacement effect.
This usually also ensures that sacrifice contact 38 is contactless in the plugged state and does not therefore recline and is constructed to use
In the contact surface 28 of the plug 16 of transmission.
For this purpose, main part can be formed correspondingly by different materials, especially non-conducting material, or at least it is coated by it.
The main part is such as hat shape main body.
Referring to Fig. 6 to 8, it will now be explained how disconnecting the connection of hot-line insertion and extraction formula attachment device 10, that is, how by plug 16
It is extracted from socket 18.
Firstly, being moved relative to each other two hot-line insertion and extraction formula connectors 12,14, so that the contact element 22 of plug 16 is along electricity
Contact surface 34,36 is slided.The electrical contact surface 34,36 of socket 18 does not contact the sacrifice contact of plug 16 during the process
Part 26.This is because the geometry of contact element 22,32, especially ramped shaped side surface 44, and it is not electrical contact surface
34,36 a part.
Meanwhile the sacrifice contact 38 of socket 18 reclines the electrical contact surface 28 of the contact element 22 of plug 16, this is logical
Crossing spring arm 40 allows sacrifice contact 38, rear area especially low in the leading edge extent of corrosion than sacrifice contact 38
Domain moves along the profile of contact element 22 and becomes possible.
Position shown in Fig. 7, two contact elements 22,32 are only electric via their sacrifice contact 26,38 each other
And mechanically couple, this is why the reason of switching arc has not yet been formed in the point.
In the position, electrical contact surface 28,34,36 have been positioned on the outside of contact area and thus be protected.
Position shown in Fig. 8, two hot-line insertion and extraction formula connectors 12,14, that is, their contact element 22,32, it is no longer mechanical
Connection allows spring arm 40 and the sacrifice contact 38 that is disposed thereon to spring back to their initial position.This is special
It can not become apparent from the comparison of Fig. 7 and 8.
In so-called " hot drawing goes out " (that is, separating umbilical connector while electric current is still transmitted by contact element 22,32
12,14) in the case where, capacitive character phenomenon can be between two contact elements 22,32, especially in two sacrifice contacts
26, switching arc S is generated between 38.This schematically shows in fig. 8.However, switching arc S occurs over just two sacrifices again
Between property contact 26,38, so that they are the unique parts corroded, and electrical contact surface 28,34,36 is not worn.This
It is due to the fact that, relative to each umbilical connector 12,14, sacrifice contact 26,38 is arranged in along direction of insertion
Front and along extract direction behind.This means that sacrifice contact 26,38 faces each other first during insertion
Component, and backmost to mutual component during extraction.
