Definitions

  • the present application relates to the technical field of electrical terminal, and in particular to a sealed terminal assembly.
  • an object of the present application is to provide a sealed terminal assembly, which can be applied to the situation of low voltage, and the volume may not increase significantly.
  • the sealed terminal assembly includes: a body having at least one conductive needle mounting hole penetrating the body; at least one conductive needle, each of the at least one conductive needle is mounted in the conductive needle mounting hole, and at least one insulating member, each of the at least one insulating member is located between the corresponding conductive needle and the body, and is used for connecting the conductive needle to the body in an insulating manner;
  • the conductive needle includes a copper core and a steel sleeve cladding the outer periphery of the copper core.
  • the copper core includes an extension portion extending along an axial direction of the conductive needle mounting hole and an expansion portion located at one end of the conductive needle, an outer dimension of the expansion portion is larger than an outer dimension of the extension portion.
  • the insulating member further includes a glass sintered piece, which is located between the body, the conductive needle and the ceramic ring and connects the body, the conductive needle and the ceramic ring in an insulating manner.
  • the conductive needle of the terminal assembly of the present application is composed of both the copper core and the steel sleeve, the copper core has a much lower electrical resistance than the steel sleeve, has good electrical conductivity when large currents pass, and therefore reduces heat generation. Meanwhile, the steel sleeve cladding the copper core retains good bonding ability with the glass sintered piece, and is suitable for the application of low voltage and high current without significantly increasing the volume.
  • the sealed terminal assembly of the present application has improved electrical conductivity and reduced heat generation, and is especially suitable for low voltage situations.
  • FIG. 1 is a perspective view of a sealed terminal assembly according to the present application
  • FIG. 2 is a cross-sectional view of the sealed terminal assembly according to the present application.
  • the sealed terminal assembly of the present application includes a body 1, at least one conductive needle 2 and at least one insulating member 3.
  • the body 1 is made of metal and has at least one conductive needle mounting hole 11 (see FIG. 4 ) passing through the body 1.
  • the number of conductive needles 2 corresponds to the number of conductive needle mounting holes 11. That is, each conductive needle 2 is mounted in the corresponding conductive needle mounting hole 11.
  • Each insulating member 3 is sleeved on the outside of the corresponding conductive needle and serves to insulate the conductive needle from the body 1. Further, the number of the conductive needles 2 also corresponds to the number of the insulating members 3.
  • the conductive needle in the present application includes a copper core 21 and a steel sleeve 22 cladding the outer periphery of the copper core 21.
  • the copper core 21 has a much smaller resistance than the steel sleeve, has good electrical conductivity when a large current passes under low voltage conditions, and thus reduces heat generation.
  • the steel sleeve 22 cladding the copper core 21 retains a good bonding ability with the insulating member 3.
  • the copper core 21 includes an extension portion 211 and an expansion portion 212.
  • the extension portion 211 extends along the axial direction of the conductive needle mounting hole 11, and the expansion portion 212 is located at one end of the extension portion.
  • An external dimension of the expansion portion is larger than an external dimension of the extension portion 211 to facilitate welding, so that the cross section of the copper core 21 is T-shaped.
  • the steel sleeve 22 clads the outer periphery of the extension portion 211 of the copper core 21.
  • the outer diameter of the expansion portion 212 of the copper core 21 is equal to the outer diameter of the steel sleeve 22 , so that the expansion portion 212 of the copper core 21 is flush with the steel sleeve 22 in the radial direction.
  • the conductive needles 2 are mounted in the conductive needle mounting holes 11 of the body 1 through the insulating member 3.
  • the insulating member 3 includes a ceramic ring 32 and a glass sintered piece 31.
  • the conductive needle 2 passes through the ceramic ring 32, and the ceramic ring 32 is placed in the conductive needle mounting hole 11. Then, a glass sintered piece 31 is formed and cured between the steel sleeve 22 of the conductive needle, the ceramic ring 32 and the body, thereby connecting them together in an insulating manner.
  • the opening 321 on one end of the ceramic ring 32 close to the body 1 is formed as a bell mouth for holding the glass sintered piece.
  • one end of the steel sleeve 22 far away from the body 1 is provided with a chamfer to facilitate installation.
  • the numbers of the conductive needles 2, the conductive needle mounting holes 11 and the insulating members 3 are respectively three. However, it is contemplated that there may be any number of conductive needles.
  • the body 1 may also have a mounting hole 12 for mounting the sealed terminal assembly.
  • the conductive needle of the terminal assembly of the present application is composed of both the copper core and the steel sleeve, the copper core has a much lower electrical resistance than the steel sleeve, has good electrical conductivity when large currents pass, and therefore reduces heat generation. Meanwhile, the steel sleeve cladding the copper core retains good bonding ability with the glass sintered piece, and is suitable for the application of low voltage and high current without significantly increasing the volume.
