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 1.56M Gy，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 wiring construction of the present invention，As shown in Figures 1 to 5，Mineral insulated cable is provided with mineral insulated cable adaptor connector，Mineral insulated cable adaptor connector includes contact、Insulator 10 and sleeve 30，Contact includes the first contact 20，First contact 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 connect by weldering cup 22 cable core and the first contact 20, mineral insulated cable adaptor connector in the present embodiment is provided with one first contact 20 and the second contact 6, wherein the second contact 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 first contacts 20 are set.
Insulator 10 is to be shaped to cylinder according to adaptation electrical connection, insulator 10 is provided with single key slot 11, when switching insulator loads mineral insulated cable adaptor connector, single key slot 11 is used for positioning and guiding, insulator 10 is provided with the contact cavity for installing contact, mineral insulated cable adaptor connector in the present embodiment has a contact and common contact part, therefore insulator 10 is provided with contact cavity 13 and common contact part installing hole 12, certainly, quantity and the shape of contact cavity connects shape according to the quantity of the contact 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 the first contact 20 and the second contact 6, along plugging together direction, rollback occurs，The electrical connection between contact and mating electrical connector is the most very likely made to lose efficacy，For avoiding the problems referred to above，Cable core arranges mineral insulated cable wiring construction，With the first contact 20, the mineral insulated cable wiring construction of the present invention is illustrated below，Mineral insulated cable wiring construction includes the stop part being enclosed within core，Stop part is sleeve 30 in the present embodiment，Stop part can also is that the block post of square block post or other shapes being provided with core installing hole in other embodiments，Sleeve 30 includes the endoporus 31 passed for core，Sleeve 30 is at the first contact 20 rear formed Stop structure，Sleeve 30 other end forms Stop structure with the outlet parts of cable 5，Occur that parts are used to be arranged on the leading-out terminal of cable 5，Simultaneously constitute the sealed end of cable 5，Cable core passes from outlet parts，Connect with corresponding contact，Outlet parts are end-blockings 4 in the present embodiment，So sleeve 30 is it is prevented that the first contact 20 is moved rearwards by，Ensure the reliability of electrical connection，The length of sleeve 30 is arranged according to the actual size of the first contact 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 contact and cable termination 4，Make to have during welding contact enough working places，End-blocking 4 is used for constituting the outlet parts 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.
The specific embodiment of the mineral insulated cable mode of connection of the present invention, first put stop part, stop part is sleeve 30 in this embodiment, stop part can also is that the block post of square block post or other shapes being provided with core installing hole in other embodiments, then by silver brazing, contact is welded on cable core, so that sleeve 30 is between the outlet parts of contact and mineral insulated cable, and described sleeve 30 two ends form Stop structure respectively at the outlet parts of described contact and mineral insulated cable, so sleeve 30 is it is prevented that the first contact 20 is moved rearwards by, ensure the reliability of electrical connection, contact in the present embodiment is identical with the contact piece structure in the embodiment of above-mentioned mineral insulated cable wiring construction with outlet parts.
