Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
nullIn the containment of nuclear power station or some be not easy to change equipment in require that electric connector has longer projected life，Also need to meet high temperature resistant (during major accident, environment peak temperature is up to 900 spend more) simultaneously、Resistance to irradiation (integral dose 1.56MGy，γ)、The environmental index such as resistance to water logging (water logging emergency conditions next year)，At this time must select mineral insulated cable，But the spacing that the manufacturing process of mineral insulated cable determines between the core of cable is less，Cannot directly and the pitch match of mating electrical connector contact，By core flexural deformation being made both pitch match，But the service life of cable can be had a strong impact on because of core flexural deformation the most again，Can also the interval of core on appropriate cable by changing the interval of contact on electric connector，But so need electric connector and matched relevant electric connector all make corresponding change，So cost is the highest，Simultaneously because the interval between core is less，When arranging the contact at same interval on electrical connectors, difficulty is the biggest，Therefore，The invention provides a kind of mineral insulated cable adaptor connector，The switching between cable core and electric connector can be realized.
nullThe specific embodiment of the mineral insulated cable adaptor connector of the present invention，As shown in Figures 1 to 5，Mineral insulated cable adaptor connector includes switching contact element 20、Switching insulator 10 and sleeve 30，Switching contact element 20 include head for along the connected structure of the first straight line and mating electrical connector contact grafting and afterbody for the wiring construction along the second straight line connecting cable core，The first described straight line and the second straight line parallel interval are arranged，Connected structure is contact pin 21 in the present embodiment，Wiring construction is weldering cup 22，Connected structure can also is that jack or chip-type contact in other embodiments，Wiring construction can be with pressure line type wiring construction，It is provided with changeover portion 20 between contact pin 21 and weldering cup 22，The changeover portion 20 cross section on vertical grafting direction is oval，Contact pin 21 and weldering cup 22 stagger setting along oval major axis，The cross section of changeover portion 20 is set to ellipse，It is to provide, to contact pin 21 and weldering cup 22, the space arranged of staggering，Avoid contact with part overall dimensions excessive simultaneously，Also save the material of contact.For meeting high temperature resistant requirement, silver brazing is used to be connected with switching contact element 20 by weldering cup 22 cable core, mineral insulated cable adaptor connector in the present embodiment is provided with a switching contact element 20 and common contact part 6, wherein common contact part 6 is identical with contact piece structure of the prior art, repeat no more, certainly, in other embodiments, it is also possible to according to the spaced relationship of the contact on mating electrical connector and cable core, two or more switching contact elements 20 are set.
Switching insulator 10 is to be shaped to cylinder according to adaptation electrical connection, switching insulator 10 is provided with single key slot 11, when switching insulator 10 loads in the housing of mineral insulation cable adaptor connector, single key slot 11 is used for positioning and guiding, switching insulator 10 is provided with the contact cavity for installing switching contact element, mineral insulated cable adaptor connector in the present embodiment has a switching contact element and common contact part, therefore switching insulator 10 is provided with switching contact element installing hole 13 and common contact part installing hole 12, certainly, quantity and the shape of contact cavity connects shape according to the quantity of the switching contact element on mineral insulated cable adaptor connector and arranges in other embodiments.
nullCable is frequent generation vibration protected from environmental and bending during using、Torsional deformation，Cable core can produce relative movement therewith，Thus drive switching contact element 20, along plugging together direction, rollback occurs，The electrical connection between switching contact element and mating electrical connector is the most very likely made to lose efficacy，For avoiding the problems referred to above，A sleeve 30 on overlapping on core，Sleeve 30 includes the endoporus 31 passed for core，Sleeve 30 is at switching contact element 20 rear formed Stop structure，Sleeve 30 other end forms Stop structure with the sealed end of cable 5，So sleeve 30 is it is prevented that switching contact element 20 is moved rearwards by，Ensure the reliability of electrical connection，The length of sleeve 30 is arranged according to the actual size of switching contact element 20 and cable core，Sleeve 30 uses stainless steel，So ensure its intensity and service life，Simultaneously，After using sleeve 30，Can ensure that the distance between switching contact element and cable termination 4，Make to have during welding switching contact element enough working places，End-blocking 4 is used for constituting the sealed end of cable，End-blocking 4 is provided with a ring flange 7，Installing hole is offered on ring flange 7，It is used for coordinating installation with mating electrical connector.
When the mineral insulated cable adaptor connector of the present invention uses, first overlap upper bush, cable core is made to stretch out from barrel forward end, then by silver brazing, switching contact element and common contact part are welded on cable core, after switching contact element is installed, switching contact element is packed on switching insulator, switching insulator is provided with for location and the single key slot of guiding, the jack making the contact pin of switching contact element and the contact of mating electrical connector aligns cooperation, the contact pin of switching contact element and weldering cup stagger and arrange formation dislocation exchanging structure, thus by switching, the interval between cable core is become big, make it can coordinate with the contact of mating electrical connector, realize electrical connection.
In other embodiments of the invention, the cross section of changeover portion can also is that kidney-shaped, and now contact pin and weldering cup stagger setting along the length direction of the kidney-shaped cross section of changeover portion.
The specific embodiment of the switching contact element of the present invention, described switching contact element is identical with the structure of the switching contact element in the enforcement of above-mentioned mineral insulated cable adaptor connector, repeats no more.
