The embodiment of the invention discloses a kind of socket conductors and jack system; Be inserted in the spring touch finger in the single line spring to realize improving in the socket conductors,, when plug plugs, evenly relax distortion with inclined to one side wire spring matching and fixing; Improve the contact performance of plug and socket, and reduce contact impedance.
Fig. 1 shows a kind of socket conductors, describes in conjunction with Fig. 2, Fig. 3 and Fig. 4:
Said socket conductors comprises: jack body 1, oblique oval bidirectional screw spring touch finger 6, single line spring 8 and partially wire spring 7 (like Fig. 3 a), wherein:
Said oblique oval bidirectional screw spring touch finger 6 is unit ring 61 (shown in Fig. 3 c) by spring wire along oblique elliptical orbit spiral surrounding; Said unit ring 61 is along axis 63 bidirectional screw coilings, first helical trajectory that said oblique elliptical orbit 61 is followed for said spring wire; Shown in Fig. 3 d, said helix 62 is the two-way track of oblique ellipse, is second helical trajectory that spring wire is followed, and axis 63 is the axis of helix 62.
Said oblique oval bidirectional screw spring touch finger 6 is enclosed within on the said single line spring 8, and adapts in the groove that embeds inclined to one side wire spring 7;
Enclose 15 in the said oblique oval bidirectional screw spring touch finger and constitute jack 10 (shown in Fig. 3 b); Said inclined to one side wire spring is installed in the said jack body hole, and said oblique oval bidirectional screw spring touch finger peripheral 9 contacts (as shown in Figure 2) with the inwall 11 of said jack body.
The oblique oval bidirectional screw spring touch finger 6 of device in said jack body 1 mesopore 2; Hole 3 is a pin head High-Voltage Insulation cap rest area; Hole 4 is the cable bonding pad; Sheath 5 is fixed in socket plastic cement insulation crust 18 (shown in Fig. 5);
Need to prove, shown in Fig. 3 b:
The unit ring outer around in point 66, the unit ring first around in point 67, the unit ring second around point 68; Wherein: around being on the unit ring 1 inner ring circle around point 68 in point 67 and the unit ring second, constitute and enclose 15 in the said oblique oval bidirectional screw spring touch finger in all unit rings first; All unit rings are outer to be on the circle of unit ring 61 outer rings around point 66, constitutes said oblique oval bidirectional screw spring touch finger peripheral 9.
Just: the spring wire on the said unit ring 61 on first helical trajectory by in the unit ring first around point 67 around to the unit ring around putting 66; At unit ring itself when spiral surrounding forms oblique oval form, with said axis 63 along said helix 62 spirals;
Wherein: said axis 63 is interior around point 67 formations second plane 69 with unit ring first, and axis 63 constitutes first plane 611 with the unit ring is outer around putting 66; Spring wire on the unit ring 61 again by the unit ring outer around point 66 around to unit ring second around point 68, simultaneously with axis 63 along helix 62 spirals, in axis 63 and the unit ring second around point 68 formations the 3rd plane 610;
First angle 64 is the angle on second plane 69 and first plane 611; Second angle 65 is the angle on second plane 69 and the 3rd plane 610, and first angle 64 guarantees that greater than second angle 65 spring wire spiral at each unit ring in the process of detouring is oblique in the unit ring.
The oval tangent plane of the diagonal of said unit ring 61 is parallel with said axis 63.Said unit ring 61 is oval 63 oval 23 the major axis of being of paralleling to the axis at the tangent plane that constitutes along the first helical trajectory spiral surrounding, and perpendicular to axis 63 be the minor axis of ellipse.
Fig. 4 shows protecting cover 13, and said protecting cover 12 is a loop configuration, and external diameter is provided with annular knurl 13, said annular knurl 13 structures and said jack body 1 internal diameter interference fit, and riveting is on said inclined to one side wire spring 7.
The protecting cover 12 of band annular knurl 13, the external diameter of band annular knurl 13 and inwall 11 interference fit of jack body 1 mesopore 2, riveting is preventing on the jack body 1 that oblique oval bidirectional screw spring touch finger 6 is shifted when plug plugs.
The strain of said oblique oval bidirectional screw spring touch finger 6 each ring is along with the insertion of plug conductors and extracts and take place gradually and produce stress deformation; The insertion of its spring touch finger is stressed to increase gradually, and extracting stressed is to reduce gradually, can improve the stressed mitigation degree of contact of plug and socket conductor inwall effectively, thereby has guaranteed the reliability of contact.Make electric current in transmittance process, reach the multiconductor contact, improve the durability in the contact use effectively, thereby reduce contact impedance.
But oblique oval bidirectional screw spring touch finger 6 one-shot formings, head and the tail do not have welding, and have the manufacturing cost that reduces owing to needing reliable soldering to bring, and have improved the economy of socket conductors.
In the said oblique oval bidirectional screw spring touch finger 6 of said single line spring 8 typings; And adapt with inclined to one side wire spring 7; Cooperate the protecting cover 12 that has annular knurl 13, not only the installation method of spring touch finger is ingenious, and can prevent effectively that spring touch finger 6 breaks away from socket conductors in plug plug process.
Parts in the said socket conductors can be by any elastic conducting material manufacturing, and smooth layer is realized in its electroplating surface (gold, silver, nickel) back.
Fig. 5 shows a kind of jack system, and is clear for what explain, is that example describes with single core socket, and Fig. 5 shows the blast structure of single core socket:
Standard cable clamp PG 17 and the insulation fixed cover 18 socket single-core cables 16 that have intermediate step; Stripping Xu's single-core cable 16 terminal crusts expose copper conductor and insert in the hole 4 of jack body 1 of said socket conductors 14 outer wall in riveting hole 4; Make single-core cable 16 be connected at 21 places with socket conductors 14; The jack body 1 of stube cable 16 is positioned in socket insulator 19 holes, and rotating insulated protective sleeve 18 makes on the insulation fixed cover 18 that screw thread 20 is connected on the screw thread 22 and socket insulator 19; Rotation standard cable clamp PG 17, make on the standard cable clamp PG 17 that screw thread 24 is connected on the screw thread 23 and the fixed cover 18 that insulate; Thereby the plug that adapts to said socket conductors 1 constitutes jack system.
Said jack system is single core form, and the energising interface that is used as single jack, and certain said single core form can be carried out the expansion of multicore aspect, realizes that many jacks energisings and many electrical equipment scene use, and is not limited to this list core form; Said jack system is particularly suitable for as the portable vehicles, uses like the socket conductors of the supply socket of electric automobile, and application scenarios is not limited thereto certainly.
In sum:
