Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1, the main structure of the present embodiment has a three parts, jack lower body, connector sleeve and connection ring set, at three
In on same axis, wherein jack lower body is fixedly connected with ring set is connect, connection be set on jack lower body with connect ring set it
Between, and connection is set in connection ring set.
Jack lower body 3 in the present embodiment generallys use the preferable copper alloy of electric conductivity, between jack lower body 3 and conducting wire
Connection both can be used out crimping hole directly carry out cold pressing mode, threaded hole can also be used or stud is connect with copper tube terminals.
Connector sleeve 1 generallys use the preferable copper alloy of electric conductivity.Inside connector sleeve, outer circle, grooved faces, slot number
Depending on according to actual needs, for loading contact cup spring.1 oral area chamfering of connector sleeve, to play the role of guiding.1 table of connector sleeve
Face should carry out conductive protection processing (such as silver-plated).Connector sleeve has been the carrier function between connecting contact pin and jack lower body.
Connection ring set 4 mainly plays the entire jack of combination and plays a very good protection to jack, plays simultaneously
X Y tri- directions Z floating position-limiting effect.Material can be metalwork, be also possible to plastic part.
Being that for most critical realizes that entire connecting contact can float using elastomeric element in the present embodiment.It is first
First, the elastomeric element used in the present embodiment is spring structure, in order to adapt to different elastic demand and installation requirements, bullet
The spring coil shape of spring structure can be ellipse section contact spring, D font section contact spring, in isoceles triangle tee section contact spring
Any one.Joining end to end for spring structure constitutes the cup spring structure of a closed loop.
It is divided into three position setting cup spring structures in the present embodiment, the structure of cup spring is as shown in Figure 3:
Firstly, the inner groove of a closed loop is arranged on the inner wall of connector sleeve, inner groove is along the inner wall surface perpendicular to axis diameter
Cup spring that is to say that the second elastomeric element is arranged in inner groove to setting.It is big according to entire contact current-carrying capacity size and space
It is small, it can choose and multiple inner grooves are set in connector sleeve, while being also provided with multiple cup springs.
Secondly, the outer groove of two closed loops is arranged in the outside wall surface of connector sleeve, outer groove is along outside wall surface perpendicular to axis
Line, which is arranged radially, that is to say that the first elastomeric element is arranged in outer groove for cup spring, so that the first elastomeric element is covered in connector sleeve
On outer surface.
Finally, an annular groove is arranged on connector sleeve end face corresponding with jack lower body, set in annular groove
Setting cup spring that is to say third elastomeric element, and annular groove and third elastomeric element center symmetric setting are on end face.The company of being equivalent to
Third elastomeric element is provided between female connector and jack lower body.
In the present embodiment, the size structure of cup spring is inconsistent between each other at three, and the function played is also inconsistent:
Firstly, contact pin passes through the cup spring of the second elastomeric element, cup spring when contact pin structure as shown in Figure 2 is inserted into connector sleeve
Minimum diameter is less than the size of the passed through part of contact pin, so that the second elastomeric element generates flexible deformation, forms contact pin and second
It is closely reliably contacted between elastomeric element and between the second elastomeric element and connector sleeve.Because connector sleeve and contact pin are worn
Crossing between part has certain gap, so the second elastomeric element can provide circumferentially slight floating space to contact pin.
Secondly, the first elastomeric element is connector sleeve and the connector for connecting ring set, the work of support Yu the big floating of circumference is played
With good reset response can be played when withdrawing from external force；Therefore it is connect when in contact pin insertion connector sleeve with the second elastomeric element
When touching, the axis of contact pin and the axis of connector sleeve occur in parallel offset (X and any orientation Y), and deviation distance, which is greater than, to be inserted
When gap between needle and connector sleeve, connector sleeve drives the first elastomeric element to deviate together, connector sleeve outer ring and connection ring
The small side in inner wall gap is covered, the first elastomeric element deformation at position is just big, and other position stress deformations gradually decrease, when slotting
When needle is extracted from connector sleeve, external force disappears, and the rock deformation pressure on the first elastomeric element circumference carries out equilibrium, so that connector sleeve moves
To initial position (axis of the axis of connector sleeve and connection ring set is overlapped), thus realize X Y two to floating.
Finally, third elastomeric element is between connector sleeve and jack lower body, when connection ring set is by connector sleeve, first, the
After three elastomeric elements combine together with jack lower body, connector sleeve, can not only be movable in X, Y circumferencial direction in connection ring set inner cavity,
Can also be lower movable in z-direction, by third elastomeric element as the carrier for connecting and supporting connector sleeve and jack lower body, initial shape
State third elastomeric element has born certain decrement, when contact pin is inserted into connector sleeve and the second elastomeric element contacts, inserts
The axis of needle and the axis angle of arrival of connector sleeve deviate (non-parallel situation is most general state), and contact pin drives connector sleeve to carry out
Angular deflection, then connector sleeve tilts in connection ring set, the gap of originally reserved Z-direction be exactly be that connector sleeve can incline
The floating space of Z-direction is tiltedly generated, third elastomeric element is flexible cup spring, so during the connection process, third elasticity
On the one hand component provides good electrical connection, on the other hand play the elastic floating of Z-direction；
The present embodiment by the cup spring of the second elastomeric element, the cup spring of the first elastomeric element, end face third elastomeric element cup spring
Luggage is packed into connector sleeve, jack lower body, connection ring to match, form plugging hole component.Plugging hole component is matched with contact pin, forms contact pair
Element.After contact pin is inserted into plugging hole component, cup spring and the contact pin of the second elastomeric element are come into full contact with, and ensure that the stability of contact
With reliability；The cup spring of the third elastomeric element of end face deviates in the axis angle of arrival of axis and connector sleeve by contact pin
It when active force, is deformed, realizes the floating of Z-direction；The cup spring of first elastomeric element is by the axis of contact pin and the axis of connector sleeve
When parallel offset occurs in line, be deformed, realize X Y two to floating.When contact pin is extracted, and external force is cancelled, end face contact spring
It can be realized and automatically reset with outer contacting spring.It ensure that continuously transmitting for electric current and signal.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
